Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal bending, in particular to an auxiliary device for sheet metal bending. Background Art

[0002] Sheet metal parts are thin metal products manufactured through cold processing technology. Sheet metal processing is mainly aimed at thin metal plates with a thickness of usually less than 6mm, involving a variety of processing methods such as shearing, stamping, bending, welding, etc. In the process of bending sheet metal parts, auxiliary tools are often used to help the sheet metal parts to be positioned, making the bending of sheet metal parts more accurate.

[0003] According to the search, Chinese patent literature, announcement number: CN211564117U, discloses an auxiliary device for bending sheet metal parts. By designing a base plate and a slot on the base plate for inserting the sheet metal parts, the sheet metal parts to be bent are inserted into the slots on the base plate. According to the required bending angle, the angle between the rotating plate and the base plate is adjusted. After the position of the rotating plate is fixed, the turntable is rotated to make the push rod rotate in the threaded hole on the mounting block, thereby driving the end of the push rod to gradually approach the extruded sheet metal part. The end of the push rod contacts the surface of the protective cover on the outside of the sheet metal part. The end of the push rod presses the sheet metal part to bend, driving the sheet metal part to be pressed tightly against the top surface of the rotating plate, and successfully bending the sheet metal part to a predetermined angle.

[0004] However, in actual use of the above-mentioned sheet metal bending auxiliary device, the sheet metal needs to be inserted into the slot and then bent manually. Although the bending angle of the sheet metal can be limited to a certain extent, the position of the bending point of the sheet metal is not limited, so it cannot assist the sheet metal in bending well.
