Description

The invention relates to the woodworking industry and can be used in lines for bending fibreboards.

The purpose of the invention is to increase productivity and simplify the design of the device.

FIG. 1 - a general view of the device; in fig. 2 - plan view of the device; in fig. 3 is a view A of FIG. one.

 The device for bending wood materials includes a frame 1, on which a vertical carousel table 4 is mounted on a vertical hollow axis 2 in bearing supports 3 and connected to a drive 5. Several punches 6 are mounted on the table and the number of dies is corresponding to it. In this case, the dies are made in the form of double walls 7, between which two closed rubberized sleeves 8 with a diameter of 100-150 mm pass. Sleeves, closed in Bt-de rings, are laid along the generatrix of the carousel table 4, and the pipe 9 through the cavity of the axis 2 and the nozzle 10 are connected to a source of compressed air,

Punches 6 by means of levers 11 are hinged on racks 12 and equipped with rollers 13. In this case, levers 11 are spring-loaded with respect to the table by springs 14.

Table device with punches and matri. It is placed in a drying chamber 15 with heaters 16. The drying chamber is closed by a lid 17, in which a loading and unloading window 18 is made with inclined side edges 19 and 20. The lid and side edges interact with the rollers 13.

A ruler 21 and an emphasis 22 are fixed to each punch on the table. The stops can interact with the limit switch 23 mounted on the frame in the workpiece loading area.

The device works as follows.

Before working in the Haka4HBaiOT sleeves 8, the compressed air and with the help of control equipment maintain the air pressure constant.

A blank 24 made of a 3 mm thick fibreboard and pre-steamed is placed on the walls 7, based on the leading edge along the ruler 21. The drive 5 is turned on, the table starts to turn, and the roller 13 rolls down the cover 17 along the inclined edge 19, bends the workpiece, pressing it between the inflated sleeves. Sleeves bend the workpiece, tightly pressing it to the face of the punch. In this state, the workpiece passes a full circle in the drying chamber.

When the next stop 22 approaches the limit switch 23, the table 4 will stop again, and the punch roller 13 will roll out along the inclined edge 20 from the drying chamber, and the spring 14 will raise the punch.

The finished bent part is removed from the table and a new billet is placed on the walls 7. Then the process is repeated,
