22.12.2016

Furniture is divided into frame and without frame. The metal frame for furniture can be made on pipe bending machines. 3-axis pipe benders allow you to produce furniture frames with a minimum number of welds.

Metal frames are used in the following types of furniture:

household (home) furniture
office furniture
medical furniture
industrial furniture
country furniture
tourist furniture
bar furniture, etc.

Pipe bender for furniture frames made of profile pipes

A pipe bender for the manufacture of furniture frames from square and rectangular pipes must necessarily be mandrel and have at least 2 coordinates, that is, they must be able to control the bend angle and extend the pipe to the starting point of the next bend. This is necessary to obtain absolutely identical parts in overall dimensions, otherwise no final product will be obtained in furniture production.

When bending square, rectangular, oval and flat-oval pipes, which fit into a circle with a diameter of 30 mm, the 2-axis manual pipe bender and semi-automatic pipe bender CE-30/2 PARTNER have proven themselves well, which provide good bending quality, high productivity and almost absolute repeatability of manufactured parts.

Pipe bender for furniture frames made of round pipes

In furniture production, in the manufacture of chair frames, beds, medical carts, strollers, wheelchairs and other medical furniture, round pipes are very often used.

In this case, 3-coordinate machines are needed, which, in addition to the bend angle, linear extension to the bend start point, are also programmed according to the pipe rotation angle in space.

Pipe benders for furniture pipes, manufactured by BMK:

Mandrel, 3-axis programmable manual pipe bender;
Semi-automatic mandrel 3-axis programmable pipe benders and;
Mandrel, 3-axis pipe bending machines and;

The presence of a mandrel ensures excellent bending quality. In addition, the mandrel allows the use of thin-walled pipes, the rigidity of which is sufficient for long-term use of furniture, and the price of pipes is much lower. Considering that pipes are sold in kilograms, there will naturally be more thin-walled pipes in meters, and therefore more furniture frames, chairs and other furniture can be produced.

For steel pipes manufactured in accordance with GOST8734-75 and GOST8732-78

A=0.02466148*S*(Dн-S), gram

For stainless pipes manufactured in accordance with GOST9941-81 and GOST9940-81

А=1.08*S / (0.08+S/D), gram

where A is the weight of one linear meter of the pipe, grams
Dn - outer diameter of the pipe, mm
S - pipe wall thickness, mm
0.02466148 / 1.08 / 0.08 - conversion factors

Accordingly, knowing the length of the blanks, you can easily calculate the required number of pipes and compare their weight and cost, and then choose the pipes of the optimal size.

Pipe bending machines of the Partner series and the Master series work perfectly with thin-walled pipes made of steel, aluminum, copper, as well as titanium.

Features of the manufacture of round seats of chairs on pipe benders.

Often the seats of chairs, bar counters are made of rings, which are easiest to make from a straight pipe, curled into a spiral with a coil to coil. Then the spiral is cut into rings. which are welded by any type of welding.
This method of manufacturing rings has become widespread when using pipe benders (profile benders) of 3-roller (roller) bending models,. These machines will allow you to get a ring, or a sector of any radius on any pipe within the technical characteristics of pipe bending machines.

So, on pipe bending machines and the minimum bending radius is 150 mm, and on pipe benders and - 300 mm. Note that on roller machines with three leading rollers, repeatability and productivity are much greater. However, only on pipe benders and with large bend radii, the need for clamping the pipe and profile can be excluded from the work cycle by synchronizing the speed of rotation of the bending rollers. This operation is performed only once at the beginning of the work shift, due to the fact that on all 3 bending rollers the angular speeds of rotation of the rollers and the linear feed rates of the bent pipe (profile) are coordinated.

Having mandrel and roller pipe benders manufactured by the Baltic Machine-Building Company (LLC BMK) in your furniture production, you will be able to realize any plans for the manufacture of frame furniture.

Stool production. Making furniture starts small.

Today, furniture manufacturers produce a wide variety of upholstered furniture designed for sitting, such as chairs, armchairs, sofas, ottomans ... The abundance of models and colors can drive a person brought up during the Soviet period crazy. But a small chair without a back with a square or round seat is still in stable demand - stool which got its name from the French language.

The “great-grandfather” of the stool is considered to be a wooden ordinary block on which people sat in primitive times. And today, it is best to start your own furniture production with the simplest, most inexpensive and necessary item, which is rightfully a stool.

The stool is compact and small in size, often used in rooms with a small area, especially in the kitchen, so it is sometimes sold as a set with a kitchen table. Stools are made of wood, plastic and metal, have 3-4 legs, sometimes with crossbars between the legs. Not so long ago, almost all stools were completed only with a hard seat, today the most widespread are upholstered stools from leather or fabric.

The availability of materials and the steady demand for stools make it possible to earn quite well on their production. Many large furniture enterprises began their history with small workshops for the manufacture of such small furniture.

For the production of simple stools it is enough to have a saw, a planer, a file, sandpaper, a board, nails, paints. Four legs and a seat are cut out of the board, then the workpieces are processed with a planer, file and sandpaper. Then the legs are nailed to the seat with nails. The surface of the finished stool is painted with paint. Everything is easy! Sizes don't really matter. Usually the seat is 33x33 cm, the leg is 45 cm long and the section is 4x4 cm.

Of course, with the help of a simple hand tool it is impossible to open a full-fledged mass furniture production. For the industrial production of furniture, you will need appropriate equipment in the form of an electric saw, turning, drilling and emery machines, an electric planer and other necessary devices.

You can make a small batch of stools at home or in the garage, but for organizing a more or less serious furniture production, including stools, you need a suitable room where furniture production will be located, as well as warehouses for materials and finished products.

In addition to the simplest designs, you can make other models of stools from various materials, using plastic, metal, precious woods, decorating them with carvings, paintings, leather upholstery of a soft seat. And yet, the main requirements for the product are reliability, strength, convenience and aesthetics of the design.

Drawings of various models stools, descriptions, dimensions, color illustrations and manufacturing techniques can be easily found on the Internet, so you will not have any problems with this. From a business point of view, when choosing a stool model, one should take into account the cost of the material, the complexity of manufacturing, the time spent on production and the possible price of its implementation.

It is necessary to calculate and provide for the wholesale purchase of materials: boards, slats, glue, etc. Some of them can be bought from furniture companies as production waste. Finished products can be given for sale to furniture stores.

Start simple - making stools. Having gained invaluable experience and skills, you will be able to try to make upholstered furniture in the future. By the way, for those who want to learn how to make upholstered furniture on their own, I recommend a very sensible training course from Roman Zhuravlev " Photo Video Instruction on the production of upholstered furniture at home”, a description of which you can see on our website.

There is a fairly large number of different types of furniture, but the absolute leaders among them are tables and chairs. They are in almost every residential and non-residential premises. Without them, it is impossible to imagine the activities of any organization, so organizing a small production of tables and chairs is a very profitable business.

Business idea: Production of tables and chairs

Best of all, small firms develop in the furniture production market, the number of employees of which is from 4 to 15 people, they make good money on small orders and are not competitors to large manufacturers.

If you want to organize production, then first you need to find a room. The workshop should be large (150m2).

Then you need to register a legal entity. The next step is to buy equipment. To make tables and chairs from wood, you will need a woodworking machine and tools. If it is the production of tables with a metal base, then the following is required: a drilling (organize small production) machine, a compressor, pneumatic equipment, a saw for metal, drills 2 pcs., "Bulgarians" 2 pcs., a welding machine, pistols. In the future, machines can be used in production, five pieces will be enough. The minimum number of employees in such an enterprise is five people.

By the way, it will not be superfluous if you can invest part of the money in other assets. After all, in case of an unforeseen situation, diversification will only be to your advantage!

If you decide to make furniture with your own hands, then a small room and a set of the following tools will be enough for you: a saw, drills, screwdrivers, pliers, a hacksaw, a planer, a regular and tape-shaped ruler, a drill.

It is advisable that you have a power saw and an electric drill. Having a spacious stable table with a vise will make it easier for you to make individual small parts. You can buy a tree, or get it yourself in the nearest suburban planting.

The production process is not complicated. The dimensions of a table or chair can be taken from a similar object and the design repeated. After the material for the base and legs is selected, it must be processed, cut to the desired size, fastened with screws, special glue and painted.

Finished products can be immediately sold to stores, or advertised in the media. A good master is always busy with work, which means that the business he is engaged in will be profitable.

How are chairs produced and is there any sense in such an enterprise, if we consider it as a private business? The result is tangible. After all, wood can “wear out” over the years, fashionable accents change, and with them the demand for chairs in different stylistic directions grows. What is the technology for making a chair out of wood and what is required for this?

DIY chair making steps

Cut edged boards into blanks for chairs

The first step is the mandatory cutting of the board into individual elements (blanks) that will be required in the future. For this, special multifunctional machines or saws are used, it all depends on the technology for manufacturing chairs in a particular place (house, production workshop).

Cutting into curves, additional blanks

A minimum will be required, since the usual one is inappropriate in this case. After all, the parts have curved shapes, and the workpiece should be brought closer to the ideal.

Cutting wood to length

Next comes the manufacture of blanks for legs, tsarg and prolegs for a certain length. The technology for manufacturing a chair in production in this case involves the use of.

Cleaning blanks for finishing, full-fledged production of legs, drawers, prolegs, etc. Simultaneous grinding of parts ready for assembly is also carried out. In production and in mass production, you can use a special machine for chairs, which is multifunctional and makes it possible to simultaneously carry out several actions.

In order for the subsequent connection of the grooves to the tenon to be successful, cleaning of the parts, in particular the grooves themselves, is required. A great assistant is a multi-spindle machine, and hand tools are quite useful for private craftsmen.

Spike rounding

The milling machine will help to process the spikes, which are located at the ends and have a rounded shape. This is necessary for all elements of the future chair of any shape, so that the connection is of optimal quality.

Preparing a place for dowels

A mandatory action, which is taken into account in the technology of manufacturing chairs, is the transverse, most accurate trimming of individual parts at the right angle. It is carried out with the simultaneous processing of absolutely blind holes, which are required for connection to dowels. Suitable cutting machine.

Sanding simple and complex chair elements

Fine grinding of all elements of the chair is the last stage in the processing of workpieces. This will give a smooth surface suitable for applying the paint material. Grinding machines - the choice of enterprises and private workshops. For self-cleaning of products in the manufacture of a single chair, you can use a hand tool - a grinder, planer or sandpaper.

Assembling a chair from individual elements

At the end of the work, the chair is assembled, by connecting all the parts into a dowel

A business plan is an analysis of the main aspects of a future enterprise. In this paper, we consider the production of tables and chairs.

So, let's begin:
1. Service - production of tables and chairs, you can add other wood products, shelves, frames, boards and much more to the load, working on orders.
2. Material, that is, you can buy a tree, if you have a car, you can get it yourself in the nearest suburban planting.
3. Registration of a legal entity, you will need an entrepreneurial license, that is, register yourself as a private entrepreneur.
4. Room you can rent, or use your own garage or some other room, if available.
5. Equipment first you need a minimum: a woodworking machine and tools.
6. Workers will be needed when large orders appear, but in the beginning it is quite possible to cope on your own.
7. Competitors there is always, but high-quality products at affordable prices for the population, this is a weapon in the fight against them.
8. Capital, you can get a loan, which I don’t really advise you to do, analyze the necessary costs for material, equipment and rent to start, it’s enough, huge investments are not required.
9. Prospects for this business plan- is to open your own store or factory, organize a network.
10. Clientele will appear, since there is always a need for tables, chairs, because people don’t like standing very much.

When creating a project for the production of tables and chairs, you first need to find a suitable room, at least two. For the administration of the office, the workshop, respectively, for the masters.

The best option is when the office and production area are nearby. If you organize a store selling ready-made tables and chairs indoors, it will be very convenient.
Further, according to the business plan - the acquisition of equipment and additional calculation programs for production and accounting.

Today, for the production of tables and chairs, there are a large number of machines, programs for modeling and furniture manufacturing. To start production, you need to find a minimum of tools and machines.

Recruitment: a consultant who takes orders, a designer with experience in working with production programs, a consultant and a designer can be one person, this is both profitable and convenient. To work in production, specialists are needed who are able to work with machines in the processing of materials. The store needs a salesperson.

This business plan considers the sale of finished products: selling tables and chairs in your own store, fulfilling orders on order, selling through furniture stores.
Estimated expenses: rent of premises (500,000 rubles per year); equipment (from 200,000 - 1 million rubles); materials (300,000 rubles per year); salary (from 1.2 million rubles per year). Total: 2.3 million - 3.6 million rubles in year.

Income: sales of products (400,000 rubles per month). Total: 4.8 million rubles in year.
These calculations show that the estimated payback period is about six months. You should not lose sight of the fact that the real numbers will be visible from how well organized production is.
