Abstract

The invention relates to a punching device. The punching device comprises a punching assembly, a pushing assembly and a bottom plate, wherein the punching assembly comprises a first cylinder, a switching device assembly, a punching male die assemble, a female die insert, a first guide rail, a first guide rail block and a first support; the pushing assembly comprises a second cylinder, a cylinder fixing seat, a cylinder switching plate, a driving block, a second guide rail, a second guide rail block and a second support; the punching assembly is fixed on the bottom plate through the pushing assembly. By means of the punching device, holes can be punched in product parts on a clamp, corners of products can be punched, multiple angle holes can be punched in the product parts, and the die development cost and the vehicle body development cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of molds, in particular to a punching device. Background technique [0002] There are a large number of holes on the stamped parts of automobiles that need to be punched, which generally require molds to complete. At the same time, in order to reduce the development cost of the model, it is necessary to optimize the punching times of the mold and the product. For a complex product, When the punching of all holes and edges cannot be completed in the limited number of molds, it is necessary to increase the number of molds to complete the punching of holes. [0003] In the prior art, for punching or trimming that cannot be integrated in one process mold, an additional process mold is used to complete; if there are problems such as wall corners in the stamping direction, it is necessary to punch first and then shape. [0004] The punching dies added in the existing technology are casting materials plus standard...
