[0032] As described in the background technology, existing punching machines often lack a real-time detection mechanism for material thickness during processing. Since different batches of materials may have different thicknesses, if the punching machine cannot make adaptive adjustments based on the actual thickness of the material, it may cause the punching force to be too large or too small, thereby affecting the forming quality of the workpiece and the service life of the punching machine.
[0033] In order to solve this technical problem, the utility model provides a material thickness matching structure and a punching machine.
[0034] Specifically, please refer to Figure 1 , the material thickness matching structure specifically includes:

[0036] The material thickness matching structure and punching machine provided by the utility model can detect the thickness of the material through the set sensor 107, so that the punching machine can adjust the punching force according to the thickness of the material, thereby ensuring the forming quality of the workpiece and the service life of the punching machine.
[0037] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0038] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0040] Example 1, please refer to Figure 1 , a material thickness matching structure includes a protective box 1, both sides of the protective box 1 are provided with slide grooves 101, a threaded rod 102 is inserted and connected between the two slide grooves 101, the outer surface of the threaded rod 102 is fixedly sleeved with a support plate 103, a sensor 107 is installed on one side of the support plate 103, and nuts 104 are threadedly connected at both ends of the threaded rod 102. Through the set sensor 107, the thickness of the material can be detected, so that the stamping machine can adjust the stamping force according to the thickness of the material, thereby ensuring the forming quality of the workpiece and the service life of the stamping machine, and after loosening the nut 104, the through hole 106 can be pulled up and down to adjust the height of the sensor 107.
[0041] Further, such as Figure 1As shown, a through hole 106 is provided on the support plate 103, and a threaded hole is provided on the protective box 1, in which a long-rod bolt 105 is threadedly connected. When the protective box 1 is not installed on the support frame 201, the through hole 106 is pushed to allow the sensor 107 to enter the protective box 1, and then the long-rod bolt 105 is screwed between the through hole 106 and the screw hole on the slide groove 101. At this time, the sensor 107 can be protected by the support plate 103 and the protective box 1, thereby reducing the possibility of the sensor 107 being damaged by bumps during movement or storage.

The second hydraulic cylinder 306 can drive the rack 302 connected thereto to move through the connecting plate 307, and the two driving wheels 305 can be moved closer to or farther away from each other through the gear 308 to achieve contact or separation with the material and meet the needs of materials of different widths.
[0050] The material thickness matching structure and the use process of the punching machine provided by the utility model are as follows:
[0051] For ease of understanding, this application uses A to represent the material to be stamped and marks it in the accompanying drawings. The thickness of the material is detected by the sensor 107, and then the stamping force of the first hydraulic cylinder 202 is adjusted. The motor drives the driving wheel 305 to rotate to achieve the movement of the material. The first hydraulic cylinder 202 pushes the lifting plate 203 down through the lifting plate 203. When the lifting plate 203 descends, the pressing plate 206 first contacts the material, which can press and fix the material, and then the upper mold 204 continues to descend to stamp the material.
