Key groove machining equipment for pseudo-classic architecture

The key groove machining equipment for the pseudo-classic architecture comprises a working box, a working table is arranged at the top of the working box, a supporting frame is arranged on the working table, lead screws are connected to the two sides of the supporting frame in a threaded mode, and a pressing plate is rotationally arranged at one end of each lead screw and located in the supporting frame; a hydraulic cylinder is arranged at the top of the working box, and an ejector rod of the hydraulic cylinder penetrates through the supporting frame and is connected with a pressing plate. An ejector rod of the hydraulic cylinder extends out by adjusting the reversing valve, the key mold is driven to move downwards until the bottom of the key mold is slightly pressed into a batten, gravure is obtained, if the battens of different sizes need to be embossed, the action is repeatedly executed, and when the gravure at the same position is embossed on the same batten, the batten is pulled out forwards, and the key
