As shown in fig. 1, steel strip 1000 is a great wall chain structure, one side of steel strip 1000 is adjacent to side plate 1016, and the other side of steel strip 1000 is provided with a positioning assembly. The positioning assembly includes a positioning pin 1043 capable of being laterally inserted into a slot of the great wall chain of the steel belt 1000 to fix the steel belt 1000 and a positioning plate 1023 pressing against the side of the steel belt to fix the steel belt 1000 in a horizontal direction. A base 1040 is fixedly provided on the lowermost side of the apparatus, two parallel guide rails 1050 are provided on the base 1040, a slider 1051 horizontally movable along the guide rails 1050 is provided on the guide rails 1050, a bottom plate 1026 is fixedly provided on the upper side of the slider 1051, and a support block 1025 is fixedly provided on the bottom plate 1026. Guide plates 1024 are provided on the support block 1025, the guide plates 1024 being located at the output port of the steel strip 1000 and extending outward in the conveying direction of the steel strip. Since guide plates 1024 are capable of supporting steel strip 1000, guide plates 1024, which extend steel strip 1000 outward from the output end of the device, prevent steel strip 1000 from being excessively bent and damaged. A fixing frame 1041 is further fixedly arranged on the base 1040, a first power source 1042 is arranged on the fixing frame 1041, and the first power source 1042 can push the positioning bolt 1043 to move in the horizontal direction and be inserted into a groove body of the steel belt 1000 great wall chain, so that the steel belt 1000 is accurately positioned. A pressing plate 1044 is fixedly arranged at the position of the positioning bolt 1043 close to the end. The pressing plate 1044 can move along with the positioning bolt 1043 in the horizontal direction, one end of the positioning plate 1023 is located between the pressing plate 1044 and the steel strip 1000, when the pressing plate 1044 approaches the steel strip 1000, the pressing plate 1044 can extrude the positioning plate 1023, so that the positioning plate 1023 moves in the steel strip direction, further presses the side surface of the steel strip 1000 and fixes the steel strip 1000 in the horizontal direction.

Fig. 2 shows a left side view of the device. A motor fixing seat 1060 is fixedly arranged on the base 1040, a motor 1061 is arranged on the motor fixing seat 1060, and the motor 1061 can push the component on the guide rail to move along the guide rail 1050.

The punch 1030 is easily bent and deformed when performing a steel strip punching operation without the protection of the moving block 1020, which affects the accuracy of the operation. When the movement output end 1013 of the driving source 1011 moves downward, the punch 1030 also moves downward to punch the steel strip 1000. The end of the positioning bolt 1043 is of a truncated cone-shaped structure with gradually decreasing outer diameter, the maximum outer diameter of the positioning bolt is larger than the width of the groove body inside the steel belt 1000, and the minimum radius of the positioning bolt is smaller than the width of the groove body inside the steel belt 1000. The positioning pin 1043 is slowly inserted into the groove of the steel band 1000, and can fix the steel band 1000. Since the steel strip 1000 has a great wall chain structure, a plurality of slots are present. A lower die 1031 is arranged in a groove body adjacent to the groove body where the positioning bolt 1043 is arranged, and a lower die hole matched with the punch 1030 is formed in the lower die 1031. As shown in fig. 1, the positioning pin 1043 and the pressing plate 1044 can move towards the steel belt under the action of the first power source 1042.

The lower die 1031 is movable horizontally with respect to the steel strip 1000. When the steel strip 1000 needs to be punched, the positioning pin 1043 and the lower die 1031 are gradually brought close to the steel strip and inserted into two adjacent slots of the steel strip 1000, respectively, and then the punch 1030 is moved downward under the control of the driving source 1011 to punch the steel strip 1000, thereby realizing the steel strip punching operation. After that, the positioning bolt 1043 and the lower die 1031 are removed from the slot of the steel belt, and the steel belt 1000 can be continuously transported backwards. And then, when the punching operation is needed, the positioning bolt 1043 and the lower die 1031 are inserted into the groove body of the steel belt 1000, and the steel belt punching operation is performed again, and the steps are repeated. The lower fixing part 1022 is provided with a fixing block 1033 at the lower side, the fixing block 1033 is internally provided with a vertically downward chip removal hole 1032, the chip removal hole 1032 is positioned at the lower side of the lower die hole of the lower die 1031, and the diameter of the hole is larger than that of the lower die hole, so that the metal chips can be discharged conveniently.

Fig. 4 is a front view of the present invention, M is a steel strip impact motion limiting module of the present device, and fig. 5 is an enlarged schematic view of the area M in fig. 4. In the process of carrying out steel belt punching operation by the device, the steel belt punching motion limiting module carries out position limitation on the vertical motion of the motion block 1020 of the device. The steel belt breaking motion limiting module comprises a downward motion limiting assembly and an upward motion limiting assembly. The downward movement limiting assembly comprises a fixed small block I1071, an upper shading plate 1072 and a position sensor I1073. The upward motion limiting assembly comprises a second fixed small block 1074, a lower light shielding plate 1075 and a second position sensor 1076. A moving reference plate 1070 is fixedly installed on the fixed base 1012, and a first position sensor 1073 and a second position sensor 1076, which can transmit an electric signal to the driving module, are fixedly installed at the same height of the moving reference plate 1070. An upper movable plate 1015 is fixedly arranged on the moving block 1020, a first fixed small block 1071 is arranged on the upper movable plate 1015, an upper light shielding plate 1072 is arranged on the first fixed small block 1071, and the upper light shielding plate 1072 can be finely adjusted in the vertical direction relative to the first fixed small block 1071 and then is fixed on the first fixed small block 1071 by screws. In the process of moving the moving block 1020 in the vertical direction, the upper light shielding plate 1072 also moves in the vertical direction together with the moving block, the upper light shielding plate 1072 slowly approaches the first position sensor 1073 in the process of moving downwards, and when the upper light shielding plate 1072 and the first position sensor 1073 are at the same horizontal position, the first position sensor 1073 transmits a signal to the driving module, and the movement stops. A second fixed small block 1074 is provided on the upper movable plate 1015, a lower light shielding plate 1075 is provided on the second fixed small block 1074, and the lower light shielding plate 1075 can be finely adjusted in the vertical direction with respect to the second fixed small block 1074 and then fixed to the second fixed small block 1074 by screws. The lower light-shielding plate 1075 is below the upper light-shielding plate 1072. In the process of moving the moving block 1020 in the vertical direction, the lower light shielding plate 1075 also moves in the vertical direction together with the moving block, the lower light shielding plate 1075 slowly approaches the second position sensor 1076 in the process of moving upwards, and when the lower light shielding plate 1075 and the second position sensor 1076 are at the same horizontal position, the second position sensor 1076 transmits a signal to the driving module, and the movement stops. Therefore, the movement of the movement block 1020 in the vertical direction can be limited at the highest position and the lowest position by the combined action of the downward movement limiting assembly and the upward movement limiting assembly, so that the impact-breaking operation can be accurately and rapidly realized. In addition, since the upper light shielding plate 1072 and the lower light shielding plate 1075 can be finely adjusted with respect to the upper moving plate 1015 and then fixed to the upper moving plate 1015 by screws, the highest position and the lowest position of the corresponding upper moving plate 1015 moving in the vertical direction can also be finely adjusted according to requirements.
