The front end of the spring 43 is hooked on the surface of the lower end of the connecting bolt 41. By setting the spring 43, under the action of its pulling force rebound, the main cutting cam 1 and the auxiliary ejector cam 2 rotate to drive the hard guide rail 5 and the double-slider linear guide rail 6 to move and then be able to return to their positions, thereby realizing a reciprocating cyclic movement, and thus realizing a reciprocating cutting movement and an ejector pin limiting action. The rear end of the spring 43 is hooked on the surface of the front end of the lower hook bolt 42.

[0019] Please refer to Figure 1 and Figure 2 , a fixed mold base 9 is installed on the surface of the front end of the machine base 14, and a movable mold base 10 is installed on the surface of the front end of the hard guide rail 5.

[0021] Please refer to Figure 2 and Figure 3, a driving disc 13 is fixedly sleeved on the left end surface of the main shaft 11 through bolts. By setting the driving disc 13, it is convenient to drive its rotation through a synchronous belt, and then drive the main shaft 11 to rotate, so that the main cutting cam 1 and the auxiliary ejector cam 2 rotate. A fastening nut is threadedly sleeved on the right end surface of the main shaft 11. By setting the fastening nut, the main shaft 11 has threads, and then it is used to tighten the cam to the main shaft 11.

[0022] Embodiment 1:

[0023] A cutting structure of a new type of wire cutting machine, including a machine base 14 and a main shaft 11.

The rear ends of the two hook bolts 42 are threadedly inlaid on the rear end surface of the machine base 14. By setting the hook bolt 42, an indirect connection is made between the spring 43 and the machine base 14, and at the same time, the length inserted into the machine base 14 can be controlled, so as to control the pulling force of the initial deformation of the spring 43. The front end of the spring 43 is hooked on the lower end surface of the connecting bolt 41. By setting the spring 43, under the action of its pulling force rebound, after the main cutting cam 1 and the auxiliary ejector cam 2 rotate to drive the hard guide rail 5 and the double-slider linear guide rail 6 to move, they can be reset, and then a reciprocating cyclic movement is realized, so as to realize a reciprocating cutting movement and an ejector pin limiting action.
