The invention relates to the woodworking industry and can be used in lines for bending wood fiber boards, in the production of curved packaging elements, furniture.

FIG. 1 shows a diagram of a general view of a device for bending; FIG. 2 is a section along A-A in FIG.

A device for bending wood-based materials includes a frame 1 on which a rotary device is mounted in the ideal of matrix 2 and a punch 3 with a drive 4. A pusher 5, having a profile of a bent workpiece, is supported on the matrix. The pusher is connected to gtrivdo m 6. |

The drying device is arranged on the right side of the a6 device and is made in the form of a metal tubular guide 7 fixed to the frame, to which copiers 8 are attached to the bottom. The radius of the tubular guide 7 is equal to the radius of the convex surface of the punch 3, and the copiers have a concave the surface is identical to the surface of the die 2. The guide 7 is fixed on the frame with the help of gussets 9, on which the adjustable guides 10 are also mounted.

  Copiers are installed in vertical guides1 11, spring-wise relative to the frame 12 mounted on rods 13. At the same time between the frame and copiers, with the ability to interact with the latter, there is a pneumatic chamber actuator 14, made in the form of a sealed sleeve connected through a fitting and tap compressed air source.

The copiers are also made with oval holes 15, with which they are mounted on a pipe 16 fixedly attached to the frame. At the transfer end of the pipe 16, an emphasis 17 is made in the form of a shoulder to which the copiers are pressed.

Tubes 18 and 19 for supplying hot water or steam are connected to the tubular guide 7 and the pipe 16.

A device for bending wood materials works as follows.

The workpiece 20, cut from the plates and pre-steamed on the matrix 2 under the punch 3. Include the actuator 4 and the punch bends the workpiece, giving it the shape of a concave surface of the matrix. Then, with the drive 4, the punch is raised by 1-5 mm and the drive 6 is turned on. The pusher 5 enters the gap between the punch and the die, rests against the bent workpiece, pushes it out and feeds the drying device into the gap between the guide 7 and the copiers 8. At the same time

the preform tends to unbend, with the result that it can be relocated. To prevent rebasing, the side edges of the workpiece are inserted between the guide bars 10.

With the return of the pusher 5 to its original position include the actuator 14, giving him compressed air. The camera inflates and lifts all copiers. The copiers 8 press the workpiece against the guide 7, again it is bent, as in a rotary device. The side edges of the workpiece are pressed against the rulers 10. Guide 7 and copiers 8, heated by steam, dry the steamed part of the workpiece.

After the next workpiece is bent in the die and with the drive 6 turned on the pusher 5, the drive 14 is turned off, its camera is connected to the atmosphere by a crane. The springs 12 lower the copiers, creating a gap between the guide 7 and the workpiece. In the drying unit is fed a new billet, advancing the previous step. Again, the copiers press the blanks to the guide 7.

The process then repeats.

At the outlet of the drying device, the blanks are finally dried and left with a fixed, predetermined shape.

The use of the invention allows to divide the process of bending and the process of drying, to separate them from each other. As a result, the operation cycle of the device is shortened and equals the operation cycle of the rotary device. This allows you to increase the performance of the device as a whole,
