Description

Bending device with inlaid sliding block

Technical Field

The utility model relates to a device of bending of slider is inlayed in area.

Background

The structure of the finished bent part is shown in fig. 1, and comprises a bottom plate 39 and a bending plate 40, wherein the bending plate 40 and the bottom plate 39 are integrally formed and are arranged at a fixed included angle with the bottom plate 39. The finished bent part is formed by bending the semi-finished part as shown in fig. 2, and the bottom plate 39 of the semi-finished bent part is disposed at an obtuse angle with the bending plate 40, so that the bending plate 40 needs to be bent at an angle relative to the bottom plate 39 so as to form an included angle between the bending plate 40 and the bottom plate 39. The existing bending method is to put the bottom plate 39 of the semi-finished bending part on the workbench 42, press the bottom plate 39 between the press block 41 and the workbench 42 by the press block 41, make the forming block 16 of the press block 41 extend into the area formed by the bottom plate 39 and the bending plate 40 of the semi-finished bending part as shown in fig. 3, then push the bending plate 40 leftwards, the pushing direction is as shown by the arrow in fig. 3, the bending plate 40 moves towards the forming block 16 direction relative to the bottom plate 39, when the bending plate 40 is attached on the inclined plane of the forming block 16 as shown in fig. 4, the required finished bending part can be obtained, finally, the finished bending part is separated from the forming block 16 of the press block 41, so as to take away the finished bending part. However, although this bending method can process the finished bent part, the following drawbacks still exist: 1. when the bending plate 40 is pushed, the bottom plate 39 is pressed between the workbench 42 and the pressing block 41, so that the bottom plate 39 and the pressing block 41 are rubbed, and the top surface of the bottom plate 39 has friction traces after bending, thereby reducing the surface quality of the finished bent part. 2. After bending, the bending plate 40 is tightly attached to the inclined plane of the forming block 16, so that a worker is difficult to separate the bending plate 40 from the forming block 16, the time consumption is long, and the bending efficiency is reduced. 3. The need to manually knock or push the bent plate 40 is undoubtedly an increase in the labor intensity of the worker. Therefore, a bending device which can improve bending quality, improve bending efficiency and facilitate maintenance of the sliding block is needed.
