A rectangular tube corner cutting punching and shearing die 200 is installed between the gantry frame 103 and the base frame 102, so that the rectangular tube workpiece 101 can be punched and sheared. The rectangular tube corner cutting punching and shearing die 200 comprises a support plate fixedly connected to the base frame 102, a lower ear seat 201 is fixedly connected to the upper end of the support plate, an upper ear seat 202 is arranged above the lower ear seat 201, and brackets 203 are installed on the sides of the upper ear seat 202 opposite to the lower ear seat 201, a knife seat assembly is arranged between the brackets 203, and connecting rod assemblies are arranged on both sides of the upper ear seat 202, and the connecting rod assemblies play a role of force enhancement and beveling.

[0026] Among them Figure 2-Figure 4 As shown, the tool holder assembly includes an outer tool holder 204 and an inner tool holder 205, the outer tool holder 204 is symmetrically arranged on both sides of the inner tool holder 205, and an opening 206 for punching and shearing is formed between the outer tool holder 204 and the inner tool holder 205, so that the rectangular tube workpiece 101 can be placed between the tool holder assemblies, which is convenient for punching and shearing operations;

[0027] Among them Figure 2-Figure 5 As shown, the connecting rod assembly includes a pressing head 207, which is set to be V-shaped, and both ends of the pressing head 207 are rotatably connected to the connecting rod 208. A rotating shaft is set between the corresponding connecting rods 208, and both ends of the rotating shaft are connected to the rotating rod 209. The connecting rod 208 is connected to the upper ear seat 202 through the rotating rod 209, and the rotating rod 209 is rotatably connected to the upper ear seat 202. The rotation amplitude between the connecting rod 208 and the rotating rod 209 is controlled to facilitate the formation of a complete structure between the connecting rod 208, the rotating shaft and the rotating rod 209. A movable blade 210 is also installed on the outer side of the rotating shaft. The lower end of the movable blade 210 is movably connected to the lower ear seat 201. The pressing head 207 moves up and down, thereby driving the tilting movement, so as to contact the rectangular tube workpiece 101 to complete the beveling operation;
