Abstract

The invention discloses a punching die for a lower connecting plate of a cross beam of an electric automobile and relates to the technical field of manufacturing of punching dies. The punching die comprises an upper die base and a lower die base. An upper clamping plate and a stripper plate are sequentially arranged at the lower end of the upper die base. The stripper plate is hung on the upper die base through stripper screws. The stripper screws are sleeved with stripper springs. The upper die base is fixedly connected with a plurality of first punches which penetrate through the upper clamping plate and the stripper plate. A female die block is arranged at the upper end of the lower die base. A plurality of workpiece positioning blocks are arranged at the upper end of the female die block. A sliding block with an oblique plane on the outer side is arranged on one side of the female die block. A punching block with the upper end being fixedly connected with the upper die base is connected to the oblique plane of the sliding block in a pressed mode. A second punch stretching out towards the female die block is arranged on the sliding block. The female die block is provided with punching die holes corresponding to the first punches and the second punch. Compared with the prior art, the punching die has the advantages that connecting holes and installation holes of the lower connecting plate of the cross beam of the electric automobile are punched at the same time, in this way, position deviation of the connecting holes and the installation holes is avoided, and the positions of the connecting holes and the installation holes are accurate.

In above-mentioned electric automobile crossbeam lower connecting plate punching die technical scheme, technical scheme can also be more specifically: support plate is equipped with in the outside of nearly described slide block, described support plate is coated with the bolt be connected with described slide block, the described bolt place be positioned at outside described support plate is set with back-moving spring.
Further, in the both sides of described slide block, slide rail is housed.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, upper bolster of the present invention is connected with multiple first drifts through train wheel bridge and stripper, die block is equipped with in the upper end of die shoe, tool bevelled slide block in outside is housed in the side of die block, the inclined-plane of slide block is crimped with upper end and the affixed pressing block of upper bolster, slide block is equipped with the second drift stretched out to die block; Carry out punching processing to the connecting hole of electric automobile crossbeam lower connecting plate and installing hole, avoid the position of connecting hole and installing hole to occur skew, the position of connecting hole and installing hole is accurate simultaneously.
2, support plate is equipped with in the outside of nearly slide block, and support plate is coated with the bolt be connected with slide block, the bolt place be positioned at outside support plate is set with back-moving spring; Punching completes rear slider self-return under the effect of back-moving spring.
