Spherical surface cantilever type bi-directional punching die

Abstract

The invention provides a spherical surface cantilever type bi-directional punching die and belongs to the field of punching dies. The punching die comprises a lower die base and an upper die base. The lower die base is provided with a cantilever part. One end of the cantilever part is connected with the lower die base through a female die fixing base. The other end of the cantilever part serves as a working end. The working end is provided with a spherical surface. The spherical surface is provided with an upper female die body and a lower female die body in a vertically opposite mode. The upper die base is provided with an upper male die body. The lower die base is provided with a lower male die body. The upper male die body corresponds to the upper female die body. The lower male die body corresponds to the lower female die body. Clamping blocks are arranged at the positions, close to the left side and the right side of the working end, of the lower die base respectively. The clamping blocks are detachably connected with the lower die base. The spherical surface cantilever type bi-directional punching die can punch spherical surface work-pieces synchronously in two directions, the work-pieces do not need to be punched one by one, machining efficiency is improved, punching precision is greatly improved, deformation of the spherical surface work-pieces in the punching process is reduced, and the machining quality of the manufactured work-pieces is ensured.

Description

technical field [0001] The invention relates to the field of punching dies, in particular to a spherical cantilever type bidirectional punching die. Background technique [0002] The punching die is a punching die that separates the waste material along the closed contour on the blank or plate to obtain a perforated part. When punching a workpiece with opposite holes on the spherical surface, since the spherical surface is a curved surface, it is very easy to deform the workpiece during punching, and it is difficult to guarantee the processing quality of the final workpiece. The existing technology generally uses a one-way punching die to punch holes one by one. Although this method can better ensure that the workpiece does not deform during punching, the processing efficiency is low, and it needs to be clamped twice. Punching operation, and the coaxiality of the two punched holes is difficult to guarantee, and the quality of the workpiece is still not ideal. Contents of ...
