DETAILED DESCRIPTION

[0025] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a stamping machine with an anti-misalignment function, comprising a base 1 and a stamping workpiece 5, the top surface of the base 1 is fixedly connected with a stamping machine 3, the inner side of the stamping machine 3 is provided with a connecting piece 4, the top surface of the base 1 is provided with a stamping part 2, and the stamping part 2 includes: a stamping cylinder 21, a connecting block 22, a positioning shaft 23, a toggle rod 24, a reset spring 25, a support rod 26, a stamping head 27, a lifting block 28, an L-shaped plate 29, a clamping spring 210, a stamping table 211, a short rod 212, a clamping plate 213, a telescopic spring 214, a resistance block 215, a guide table 216, a spring piece 217, a trapezoidal block 218, a torsion spring 219, a vertical plate 220, and a guide roller 221.

[0026] The top surface of the punching cylinder 21 is fixedly connected to the bottom surface of the connecting piece 4. When the punching workpiece 5 needs to be punched, the punching workpiece 5 is placed on the guide roller 221, and the punching workpiece 5 is gradually pushed to be inserted between the punching table 211 and the clamping plate 213. The punching cylinder 21 is started to move downward to punch the first hole at the front end of the punching workpiece 5. The output shaft of the punching cylinder 21 is fixedly connected to the punching head 27. The side of the punching cylinder 21 is fixedly connected to the connecting block 22. The connecting block 22 is penetrated and fixedly connected by the positioning shaft 23. The positioning shaft 2 3 penetrates and is rotatably connected with a toggle rod 24, and the trapezoidal block 218 is engaged with the punched hole. At this time, there is no need to push the punched workpiece 5, and the punching cylinder 21 is continued to be started. When the punching cylinder 21 moves downward, it will drive the connecting block 22 to move downward, so that the positioning shaft 23 drives the toggle rod 24 to move downward, and further makes the semicircular arc at the bottom of the toggle rod 24 conflict with the inclined surface of the abutment block 215, so that the toggle rod 24 rotates with the positioning shaft 23 as the axis. The toggle rod 24 is fixedly connected to the surface of one side of the connecting block 22 with a return spring 25. One end of the return spring 25 away from the toggle rod 24 is fixedly connected to the inner side of the connecting block 22, and the side of the lifting block 28 close to the stamping cylinder 21 is fixedly connected to the side of the stamping cylinder 21. The bottom surface of the lifting block 28 is fixedly connected with a support rod 26, and the support rod 26 penetrates and is slidably connected with an L-shaped plate 29. A clamping spring 210 is fixedly connected between the L-shaped plate 29 and the lifting block 28. When the stamping cylinder 21 moves downward, it will drive the lifting block 28 to move downward, and the lifting block 28 will drive the support rod 26 to move downward, and the lifting block 28 will be clamped by the clamping spring 21 0 drives the L-shaped plate 29 to press the clamping plate 213, so that the clamping plate 213 fixes the stamping workpiece 5, so that the punching head 27 is more stable when stamping the stamping workpiece 5, and prevents the position of the stamping workpiece 5 from shifting. The stamping table 211 is fixedly connected to the surface of the base 1 by bolts, and the stamping table 211 is penetrated and slidably connected by the short rod 212. The top surface of the short rod 212 is fixedly connected with the clamping plate 213, and a telescopic spring 214 is fixedly connected between the clamping plate 213 and the stamping table 211. The left surface of the stamping table 211 is fixedly connected with a resistance block 215. The top surface of the base 1 is fixedly connected with a guide platform 216 by bolts. A spring piece 217 is hinged on the side surface of the guide platform 216 close to the punching platform 211. The top surface of the spring piece 217 is fixedly connected with a trapezoidal block 218. The punching workpiece 5 is continuously pushed. After punching a plurality of holes continuously, the punching workpiece 5 is pressed against the inclined surface of the trapezoidal block 218, so that the trapezoidal block 218 drives the spring piece 217 to rotate downward. When the punched hole of the punching workpiece 5 coincides with the position of the trapezoidal block 218, the torsion spring 219 will bounce the spring piece 217 and make the trapezoidal block 218 fit with the punched hole. The torsion spring 219 is fixedly connected between the spring piece 217 and the guide platform 216. The top surface of the base 1 is fixedly connected with a vertical plate 220. There are two groups of vertical plates 220, and the two groups of vertical plates 220 are fixedly connected with the top surface of the base 1 respectively.The vertical plates 220 are penetrated and rotatably connected by guide rollers 221. The cross section of the abutment block 215 is trapezoidal, and the inclined surface faces the toggle rod 24. The bottom surface of the toggle rod 24 is semicircular.

[0027] The inclined portion of the trapezoidal block 218 faces the stamping table 211, and when the toggle rod 24 moves downward, it will be inserted into the hole opened in front of the stamping workpiece 5. Therefore, when the toggle rod 24 rotates, it will toggle the stamping workpiece 5, so that the stamping workpiece 5 is automatically loaded in the direction of the guide table 216, and the punched hole will contact the trapezoidal block 218. The left side of the trapezoidal block 218 is a vertical surface. Therefore, when the stamping cylinder 21 is raised, the return spring 25 pulls the toggle rod 24 to reset. Since the vertical surface of the trapezoidal block 218 contacts the inner side of the punched hole, the toggle rod 24 is prevented from pushing the stamped workpiece 5 back.

[0028] Based on the above embodiment, when the stamping workpiece 5 needs to be stamped, the stamping workpiece 5 is placed on the guide roller 221, and the stamping workpiece 5 is gradually pushed to be inserted between the stamping table 211 and the clamping plate 213, and the stamping cylinder 21 is started, so that the stamping cylinder 21 moves downward to punch the first hole at the front end of the stamping workpiece 5. At this time, the stamping workpiece 5 continues to be pushed. After continuously punching multiple holes, the stamping workpiece 5 is pressed against the inclined surface of the trapezoidal block 218, so that the trapezoidal block 218 drives the spring piece 217 to rotate downward. When the hole punched by the stamping workpiece 5 coincides with the position of the trapezoidal block 218, the torsion spring 219 will bounce the spring piece 217 up, and make the trapezoidal block 218 fit with the punched hole. At this time, there is no need to push the stamping workpiece 5, and the stamping cylinder 21 is continued to be started. When the stamping cylinder 21 moves downward, it will drive the connecting block 22 to move downward, so that the positioning shaft 23 drives the toggle rod 24 to move downward, further making the toggle rod 24 move downward. The semicircular arc at the bottom of the moving rod 24 conflicts with the inclined surface of the conflicting block 215, so that the toggle rod 24 rotates with the positioning shaft 23 as the axis, and when the toggle rod 24 moves downward, it will be inserted into the hole opened in front of the punching workpiece 5. Therefore, when the toggle rod 24 rotates, the punching workpiece 5 will be moved, so that the punching workpiece 5 will automatically be loaded in the direction of the guide table 216, and the punched hole will conflict with the trapezoidal block 218, and the left side of the trapezoidal block 218 It is a vertical surface, so when the stamping cylinder 21 is raised, the reset spring 25 pulls the toggle rod 24 to reset. Since the vertical surface of the trapezoidal block 218 contacts the inner side of the punched hole, the toggle rod 24 is prevented from pushing the stamped workpiece 5 back. By repeatedly starting the stamping cylinder 21, automatic loading can be achieved, and the distance between the punched holes is equal. In addition, the stamped workpiece 5 is limited in one direction by the trapezoidal block 218 to prevent the stamping head 27 from causing dislocation when punching the workpiece 5.

[0029] At the same time, when the stamping cylinder 21 moves downward, it will drive the lifting block 28 to move downward, and the lifting block 28 will drive the support rod 26 to move downward, and the lifting block 28 will drive the L-shaped plate 29 to press the clamping plate 213 through the clamping spring 210, so that the clamping plate 213 fixes the stamping workpiece 5, making the stamping head 27 more stable when stamping the stamping workpiece 5, preventing the position of the stamping workpiece 5 from shifting.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
