Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal bending, in particular to a sheet metal bending device with controllable angle. Background Art

[0002] Sheet metal is generally made by manually or by die stamping some thin metal plates to produce plastic deformation to form the desired shape and size, and can be further formed into more complex parts through welding or a small amount of mechanical processing. For example, chimneys, iron stoves, and car shells commonly used in households are all sheet metal parts. In order to facilitate the bending of sheet metal into different angles, a sheet metal bending device with controllable angle is needed.

[0003] Existing sheet metal bending devices generally include a workbench, a V-shaped groove arranged on the upper end surface of the workbench, and a bending knife located above the V-shaped groove. When in use, the sheet metal to be bent is placed on the upper end of the V-shaped groove, and then the bending knife moves downward and forces the sheet metal into the interior of the V-shaped groove to complete the bending of the sheet metal.

[0004] The shortcomings of the existing sheet metal bending device are: since the V-groove is a fixed integrated structure, it is not convenient to adjust the bending angle between the two sides of the inner wall of the V-groove according to actual production requirements, and the practicality is low. Therefore, it is necessary to propose an angle-controllable sheet metal bending device to solve the above-mentioned problems. Utility Model Content

[0008] In order to improve the stability of the movement of the sliding frame, as a preferred angle-controllable sheet metal bending device of the utility model, the sliding frame is slidably connected to the left and right sides of the inner wall of the fixed platform through sliding rails.

[0009] In order to facilitate the rotation of the threaded sleeve, as a preferred angle-controllable sheet metal bending device of the utility model, the lower end of the threaded sleeve is fixedly connected with a knob extending to the bottom of the fixed platform.

[0010] In order to achieve an anti-slip effect when turning the knob, as a preferred angle-controllable sheet metal bending device of the utility model, the outer wall of the knob is provided with anti-slip grooves.

[0011] In order to facilitate the fitting of the outer wall of the bearing to improve the fixing effect of the bearing, as a preferred angle-controllable sheet metal bending device of the utility model, the interior of the mounting frame is an annular structure.

[0012] In order to facilitate supporting the device, as a preferred angle-controllable sheet metal bending device of the utility model, legs are fixedly connected to the four corners of the lower end surface of the fixed platform.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
