Problems solved by technology
[0005] In order to make up for the deficiencies of the prior art, and to solve the problems that in the existing sheet metal bending abrasive tools, debris is generated when the sheet metal is bent, errors are caused to the sheet metal parts after bending, and the bending of the sheet metal parts by a single mold is relatively simple, the present invention A sheet metal bending die is proposed

specific Embodiment approach
[0038] As a specific embodiment of the present invention, the clamping block 252 is an arc-shaped block, and the clamping block 252 and the second rotating column 22 have the same circle center;
[0039] When in use, when the shape of the block 252 is an arc block, when the forward and reverse motor rotates, the No. 1 rotating column 21 rotates with the No. 2 rotating column 22, and when the sheet metal parts rotate around the No. 2 rotating column 22 When bending, the block 252 pops out from the slot 25 to limit the position of the sheet metal. When the block 252 is arc-shaped, on the one hand, when the sheet metal is bent, the contact between the block 252 and the sheet metal The area becomes larger, the block 252 further limits the sheet metal, and the contact area between the block 252 and the sheet metal increases, so that the elastic deformation of the sheet metal is avoided after bending, and the error generated when the sheet metal is bent is reduced. On the other hand...

The invention relates to the technical field of sheet metal machining and production, in particular to a sheet metal bending die. By arranging an annular block, a forward and reverse rotation motor and a rotating unit, when the forward and reverse rotation motor rotates, a first rotating column rotates, and a first clamping column and a second rotating column rotate along with the first rotating column, so that a sheet metal part is bent around the second rotating column, and arc bending of the sheet metal part is achieved; when the sheet metal part rotates and bends, the sheet metal part no longer extrudes the clamping block, the clamping block pops up, when the clamping block pops up completely, bending of the sheet metal part is finished, a pressing column at one end of an electric telescopic air cylinder extrudes downwards, and the use efficiency of the sheet metal part bending device is improved; when the arc-shaped sliding block slides in the first annular groove, the arc-shaped sliding block extrudes the stacked air bag, air in the stacked air bag is sprayed out through a through hole, the air cleans scraps on the inner surface of the sheet metal part, the error is small when the sheet metal part is tightly attached to the second rotating column, and the bending accuracy of the sheet metal part is improved.
Description
technical field [0001] The invention relates to the technical field of sheet metal processing and production, in particular to a sheet metal bending die. Background technique [0002] In the process of sheet metal processing, processes such as punching, bending and flattening are indispensable, and sheet metal processing includes traditional methods and process parameters such as cutting and blanking, punching, bending and pressing, and includes Various cold stamping die structures and process parameters, various equipment working principles and operating methods, as well as new stamping technologies and new processes. At present, the plates formed by the existing sheet metal grooving punching need to be bent. To achieve bending, the operation of the bending mold reduces the difficulty of work and saves time and effort. However, the previous bending molds tend to cause the raw material sheet metal to break during the bending process, and the bent bracket is also easy to spri...
