High-precision stamping die assembly with safety protection function

Abstract

The invention discloses a high-precision stamping die assembly with a safety protection function. The high-precision stamping die assembly has reliable hydraulic power and has the reliable safety protection function, and meanwhile a male die can be replaced. The high-precision stamping die assembly comprises a rack, an upper die assembly and a lower die assembly, wherein the upper die assembly and the lower die assembly are arranged on the rack and opposite to each other, and the upper die assembly is located above the lower die assembly. The upper die assembly is driven through a hydraulic oil cylinder assembly to ascend and descend. The upper die assembly and the lower die assembly are provided with the male die and a female die which are matched with each other respectively. The upper die assembly further comprises a male die assembly fixed to the bottom face of a lifting board. The male die assembly comprises a fixing board fixedly connected to the bottom face of the lifting board. The fixing board is provided with a male die fixing base connection hole. A male die fixing base is connected into the male die fixing base connection hole. An axial connection hole is formed in the male die fixing base. A male die mechanism is connected into the axial connection hole in a matched manner. The side wall of the female die of the lower die assembly is provided with an infrared transmitting head and an infrared receiving head.

Description

technical field [0001] The invention relates to a stamping die, in particular to a high-precision stamping die. Background technique [0002] When stamping flat materials, we found that the existing stamping dies have potential safety hazards. When the punch in the upper die assembly moves towards the die in the lower die assembly, it cannot sense whether there is an object other than the workpiece. , so it is very easy to cause damage to human body parts that have entered by mistake or have not completely left from the vicinity of the workpiece; to avoid this situation, the current design idea is to prevent the start switch from being touched by mistake or set two buttons to be pressed at the same time to start Structure; this structure brings the complexity of the operation, and because it is not directly determined whether there is a foreign body in the stamping area, there is still a safety hazard; [0003] In the stamping die assembly we currently use, the movement of ...
