The task is to eliminate the torsion of parts made of sheet and having any length. This object is achieved in that the device for editing parts from a sheet contains two racks 1 and 2, mounted on a rigid base 3, while one of the racks is made to rotate the bracket, and the second rack and bracket are equipped with clamps 6 located on the side from straightened parts 7. 1 s.p. f-ly, 6 ill.

Description

The utility model relates to the field of engineering and can be used to edit twisted relative to the longitudinal axis of parts of any length made of sheet.

A device for editing long workpieces with surfaces is known. When using this device 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 in one direction. Subsequent bending is carried out from the middle to the edges of the workpiece. This eliminates the boxiness and supposedly torsion of the workpiece (propeller), 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 30 ... 40 mm (USSR author's certificate No. 1779430 publ. 07.12.92 bul. .45).

A device for dressing parts made of a sheet, consisting of two racks mounted on a press plate or other rigid base. In one rack is fixed, with the possibility of rotation of the bracket. On the second rack and bracket there are clamps for fixing the part to be edited (see the description of the utility model certificate No. 22079 V21D 1/06, 2002). The disadvantage of this device is the imperfection of the design, which allows you to edit parts of only a certain length, which are placed between the racks.

The task is to eliminate the torsion of parts made of sheet and having any length.

The problem is achieved in that in the device for editing parts from a sheet containing two racks mounted on a rigid base, while one of the racks is mounted, with the possibility of rotation, the bracket, and

the second rack and bracket are equipped with clamps located on the side of the straightened parts.

The essence of the claimed is illustrated by drawings, where:

figure 1 - General view of the device;

figure 2 is a view a of figure 1;

figure 3 is a view B of figure 1;

figure 4 is a view In figure 1;

figure 5 - element D of figure 4;

Fig.6 is a view D of Fig.5.

The device contains racks 1 and 2, mounted on a rigid base 3.

In the rack 2 on the rollers 4 mounted bracket 5, made with the possibility of rotation. On the rack 1 and the bracket 5 there are clamps 6 for fixing parts 7 to be edited. Depending on the direction of editing, one of the clamps 6 mounted on the bracket 5 is equipped with a pusher 8 that transmits the force P from the press (not shown in the drawing) and is fixed with a screw 9.

To combine the middle of the width H of the part 7 with the axis of rotation of the bracket 5, there are stops 10 on it and on the rack 1, which are mounted and fixed at a distance N / 2 from the risks with a width of 1 mm and a depth of 1 mm applied to the bracket 5 and rack 1 and matching with the axis of rotation of the bracket 5. The rollers 4, on which the bracket 5 is rotated, are fixed in the rack 2 on the axes 11, and the clamps 6 clamp the installed part using wedges 12.

To match the axis of rotation O along the radius R of the bracket 5 and the axis of the installed part 7, depending on its thickness 6, pads 13 are installed on the bracket 5 and the rack 1.

The device operates as follows. On the bracket 5 and the rack 1 fix the stops 10, depending on the actual width of the part to be edited. After that, the bracket 5 and the rack 1 is installed

part 7 to be edited, and clamped with clamps 6 using wedges 12.

Depending on the direction of torsion of the part, the bracket 5 occupies a position in which one of the clamps 6 will be higher than the other. A pusher 8 is mounted on it and secured with a screw 9. After turning on the press, the force 5 is transmitted to the bracket 5 through the pusher 8 so that the bracket 5, turning on the rollers 4, untwists the part, thereby eliminating the torsion defect.

After checking the quality of the part, it is removed from the device or the unwinding operation is repeated until the defect is completely eliminated.
