The utility model relates to the field of mechanical engineering and can be used for dressing flat parts made of worm.

A device for editing discs containing the upper and lower traverses, made in the form of crossing strips, the ends of which are paired with columns. One pair of columns is rigidly connected to the bed, and on the traverses, concentric supports are mounted alternately, forming the plane of the disk clamp. With the mutual movement of the concentric bearings of the hydraulic cylinder W, a shear deformation is created in the machined disk, which enhances the quality of the dressing.

The disadvantage of this device is that it can only be used to edit parts in the form of disks having a small thickness (a.s., 1779431, publ. 07L2.92 bul. 45).

A known method of editing long workpieces with flat surfaces. When using this method in bending machines, machine tools and presses, dressing is carried out in two stages. The initial bending of the workpiece is carried out to convert the straightened surface into a cylindrical surface of variable curvature of one direction. Subsequent bending is carried out from the middle to the edges of the workpiece. At the same time, it eliminates its boxiness and supposedly torsion of the workpiece. In fact, it is practically impossible to fix the torsion of the workpiece in this way, especially if the workpiece is made of a sheet of large thickness (A.S. 17949430, publ. 07D2.92 bull. 45).

The proposed utility model solves the problem of eliminating the torsion of flat parts made of sheet.

To reach: the indicated result in a device for straightening sheet flat parts containing two racks mounted on a press plate, a bracket is mounted with a possibility of rotation on one of the racks, pryzhsh / gy are mounted on the other racket and bracket, one of the pry ya is equipped with a pusher, through which the force is transmitted from the press to the bracket, which, turning in the rack, untwists the part, thereby eliminating the defect.

The proposed utility model is illustrated in the drawing / w shown in Figs. 1 and 2 in FIG.

In Fig. L is a general view of the device.

Figure 2 is a view A of figure 1.

The device consists of a rack I and a rack 2, mounted on a prepress plate or on any other rigid base 3. A bracket 4 is mounted in the rack 2, can be rotated, clips 5 and b are mounted on the rack I and bracket 4 to fix the part 7, subject to editing. Depending on the direction of editing, a pusher 8 is installed on the clamp 6, which transfers the force P from the press. To match the axis of rotation of the bracket 4 and the axis of the installed part, depending on its thickness, there are pads 9 on the bracket 4 and on the rack I, and to combine the middle of the width of the part 7 with the axis of rotation of the bracket 4, the risk is applied at the last 10 of width I mi and a depth of I mm.

The device operates as follows. On the rack I and the bracket 4, the part to be edited is installed and fixed by clamps 5 and 6.

Depending on the direction of torsion of the part, the bracket 4 occupies a position in which one of the pinches 6 will be higher than the other. On it and set the pusher: Eh, 8,

Turning on the press, the arm 4 is transmitted through the pusher 8 to a force P directed so that the arm 4, turning in the rack 2, untwists the part, thereby eliminating the defect. After checking the quality of the part, it is removed from the device or unwinding operation: continue until the defect is eliminated. Chief; k - -. ,. .- .. -L /, :: -; - N:.
