It includes a tool clamp plate and a punching and shearing plate, wherein the punching and shearing plate is arranged between the tool clamp plates, and there are two tool clamp plates, and the outer surface of the tool clamp plates is provided with a workpiece jaw, and a retaining screw hole is provided above the workpiece jaw. In order to solve the problem that the tool used in the existing punching and shearing machine can only exert unidirectional pressure on the workpiece during the punching and shearing process, which will cause obvious biased burrs in the fracture area, a set of guide connecting rods are installed on both sides of the punching and shearing plate. With the help of the guide connecting rods, the offset between the punching and shearing plate and the tool clamp plate during the activity can be avoided, resulting in a change in the direction of the fracture burr, affecting the subsequent trimming operation.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In order to solve the problem that when the punching shears are installed on the punching shears in the prior art, when the punching shears cut the material with low rigidity, the cut part of the material may stick to the blade of the punching shears, so that when the punching shears perform the next cutting work, the part of the material stuck on the punching shears and the material to be cut may overlap and be cut, and the excessively thick material may damage the blade groove of the punching shears, refer to Figure 1-3 , this embodiment provides the following technical solutions:

[0020] A protection and limiting structure for a slot of an alloy punching shears comprises a ground contact base 1, a connecting rod 11 is arranged on the ground contact base 1, a connecting base 12 is arranged on one end of the connecting rod 11 away from the ground contact base 1, a conveyor belt 13 is arranged on one side of the connecting base 12, and a rotating motor 14 is arranged on the other side of the connecting base 12 away from the conveyor belt 13, an output end of the rotating motor 14 is connected to a rotating shaft of the conveyor belt 13, and a driven shaft 15 is arranged on the end of the conveyor belt 13 away from the rotating motor 14, a fixing block 2 is arranged on the ground contact base 1, a supporting column 8 is arranged on the fixing block 2, an elastic telescopic rod 9 is arranged on the end of the supporting column 8 away from the fixing block 2, a limiting support plate 10 is arranged on the fixing block 2, and a reserved bolt hole 3 is opened on the ground contact base 1, and the reserved bolt hole 3 is arranged integrally with the ground contact base 1;

[0023] Working principle: When the user needs to perform knife groove protection work on the punching scissors, first place the ground contact base 1 at the lower end of the side where the punching scissors are installed on the punching and shearing machine, so that the conveyor belt 13 is at the lower end of the side of the punching scissors. When the staff places the material at the lower end of the punching scissors, the punching and shearing machine drives the punching scissors to fall and cut the material. Then the cut material falls onto the conveyor belt 13, and the rotating motor 14 drives the material to be transported forward away from the bottom of the punching scissors. Because the punching scissors on the punching and shearing machine are generally composed of two sets of punching scissors, when the punching and shearing machine fails, it may cause the upper punching scissors to fall abnormally and directly hit the punching scissors below. At this time, the punching scissors The fixed structure will contact with the elastic telescopic rod 9, and the elastic telescopic rod 9 will be pressed down by the fixed structure of the punching and shearing machine, and then the fixed structure will contact with the limiting support plate 10, and the limiting support plate 10 will support the falling fixed structure of the punching and shearing machine to stop the punching and shearing machine from falling. When the staff turns off the punching and shearing machine, the elastic telescopic rod 9 will pop up the fixed structure of the punching and shearing machine to reset it.
