It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0023] Reference Figure 1-4 A punching device includes a chassis 1, a stand 2 is connected to the top of the chassis 1, a punching assembly 3 is installed on the top of the stand 2, the punching assembly 3 includes a hydraulic cylinder 31 connected and fixed to the top of the stand 2, the output end of the hydraulic cylinder 31 passes through the stand 2 and is connected to an upper connecting plate 32, and the bottom end of the upper connecting plate 32 is docked with a lower connecting plate 33 by bolts, and the center position of the bottom end of the lower connecting plate 33 is docked and fixed with a punching head 35 by a docking component 34, a clamp ring 37 is sleeved on the outer side of the docking component 34, and a support spring 36 is connected to the top of the clamp ring 37, and the top of the support spring 36 is connected and fixed to the lower connecting plate 33.
[0024] Two guide assemblies 5 are symmetrically arranged on the top side of the chassis 1. The guide assembly 5 includes a guide block 51. A track plate 52 is connected to the left side of the guide block 51. A threaded shaft 53 is rotatably connected to the outer side of the guide block 51, and the threaded shaft 53 passes through the outer side of the chassis 1 through a threaded hole.
[0025] The guide block 51 has an L-shaped structure through a vertical section, and the guide block 51 is embedded in the surface of the chassis 1 through a guide groove.
[0026] The docking component 34 includes a docking tube 341, the top of which is connected and fixed to the lower connecting plate 33, the bottom of which is embedded with an insertion shaft 343 through a polygonal slot, and the bottom of the insertion shaft 343 is connected to a connecting plate 344, and the bottom of the connecting plate 344 is connected to a punching head 35.
[0027] Two clamping blocks 342 are rotatably mounted on the outer side of the docking tube 341 , and the clamping blocks 342 are inserted into the sides of the docking plate 344 through the clamping grooves.
[0028] The left and right sides of the bottom end of the lower connecting plate 33 are symmetrically connected with the pressing assembly 4 , and the pressing assembly 4 includes an auxiliary support spring 42 , and the bottom end of the auxiliary support spring 42 is connected with a square frame 44 .
[0029] The top of the auxiliary support spring 42 passes through the bottom of the frame 41 through the through hole and is connected to the guide column 43 . The top of the guide column 43 is connected and fixed to the inner wall of the frame 41 . The top of the frame 41 is connected and fixed to the bottom of the lower connecting plate 33 .
[0030] By rotating and moving the threaded shaft 53, the guide block 51 can be pushed, and the guide block 51 can be pushed by force to move the track plate 52, and then the distance between the two track plates 52 can be adjusted and changed. The metal product can be limited by the two track plates 52, and the guide block 51 can be guided and limited by the guide groove at the top of the chassis 1 to prevent the guide block 51 from being offset by the rotation of the threaded shaft 53 during movement. The insertion shaft 343 and the docking tube 341 are plugged in and docked with each other, so that the convenience of disassembly and assembly of the punching head 35 is improved. At the same time, the polygonal structure design of the insertion shaft 343 can prevent the insertion shaft 343 from being offset and rotating after being inserted into the polygonal slot of the docking tube 341, which affects the punching state of the punching head 35. After the docking with the docking tube 341 is completed, the clamping block 342 can be rotated so that the clamping block 342 is buckled in the clamping groove outside the connecting plate 344 after being rotated, so as to ensure the stability of the docking between the plug shaft 343 and the docking tube 341. The square frame 44 can move along with the movement of the punching head 35. When the punching head 35 is punching, the square frame 44 can press down and restrain the metal product to ensure the stability of the metal product when punching. When the square frame 44 contacts the surface of the metal product, the frame 41 can move down along with the square frame 44 on the surface of the auxiliary support spring 42. At the same time, the guide column 43 can support the auxiliary support spring 42, so that the square frame 44 has a buffering effect, so as to avoid damage to the finished product when the square frame 44 presses down on the metal product.
[0031] Working principle: According to the attached Figure 3 As shown, when installing the punch hole head 35, the insertion shaft 343 is inserted into the slot of the docking tube 341, so that the connecting plate 344 is fitted with the bottom end of the docking tube 341, and at the same time, the clamping block 342 is rotated to make the clamping block 342 buckle and insert it into the clamping groove on the side of the connecting plate 344. At this time, the rebound force of the support spring 36 can push the clamp ring 37, and the clamp ring 37 is sleeved on the outside of the docking tube 341 and the connecting plate 344 after being stressed, and then the clamping block 342 can be limited and engaged, and then the installation of the punch hole head 35 can be completed;
[0032] Secondly, according to the attached Figure 2 With attached Figure 4 As shown, the staff can rotate the threaded shaft 53 to move the axial end of the threaded shaft 53 to push the guide block 51 to move. The guide block 51 can change the position of the track plate 52 during movement, and then the distance between the two track plates 52 can adapt to the outer diameter of the metal product. At this time, the output end of the hydraulic cylinder 31 starts to push the upper connecting plate 32, and the upper connecting plate 32 and the lower connecting plate 33 cooperate to push the docking tube 341 to move. The docking tube 341 moves and pushes the punching head 35 to move, and then punches the metal product. At this time, the square frame 44 moves down synchronously with the punching head 35. When the punching head 35 punches, the square frame 44 can move the metal product downward to ensure the stability of the metal product when punching.
