The problem that when a handle square hole is stamped by an existing handle square hole stamping device, a male die is prone to breaking is solved. The handle square hole stamping device comprises an upper die plate and a lower die plate, a male die is arranged on the upper die plate, a fixing frame is fixed to the lower die plate, a female die backing plate is arranged between the lower die plate and the fixing frame, a female die fixing plate used for placing a handle to be machined is arranged on the female die backing plate, the fixing frame is arranged outside the female die fixing plate in a sleeving mode and in clearance fit with the female die fixing plate, a fixed female die and a clamping device for clamping the handle to be machined in cooperation with the fixed female die are arranged on the female die fixing plate, and the female die backing plate is in slide fit with the lower die plate through a universal sliding block. The handle square hole stamping device has the advantages of being simple in structure, convenient to operate, low in production cost and long in service life, and the male die is not prone to breaking.
Description
technical field [0001] The invention relates to a handle square hole punching device. Background technique [0002] With the advancement of power equipment manufacturing technology, the power supply device of power equipment is becoming more and more stable. In order to further improve the automation of the power industry, various units in the power supply industry have comprehensively launched unattended transformation of substations. [0003] In the existing center-mounted insulated switchgear, in order to enable the center-mounted vacuum circuit breaker to conveniently realize the function of pushing from the experimental position to the working position and locking and withdrawing from the working position to exit the experimental position and locking, a chassis car is generally used To carry the vacuum circuit breaker, the traveling wheels on the chassis move forward or backward on the track in the switch cabinet. Existing chassis vehicles include a vehicle frame, a fi...
