Description
Technical Field
[0001] This utility model relates to the field of shoemaking equipment technology, specifically a punching machine. Background Technology
[0002] A search revealed the prior art with announcement number CN211211677U. The working principle of the punching and punching pin is as follows: each adjusting plate has punches, and several punches are correspondingly arranged to each punch. When adjusting the hole spacing of the punching machine, the hole spacing of the adjusting plates can be adjusted equidistantly in the X-axis direction, and each adjusting plate can also be adjusted separately in the Y-axis direction. After adjustment, the punches are driven by a third drive mechanism to punch holes. Therefore, the punching support is located on the adjusting plate. After prolonged use, the punches will wear down. Firstly, the wear and tear on the punches can cause waste material to adhere to the shoe upper, affecting the punching speed and quality. Secondly, when the punches wear down, the entire adjusting plate needs to be replaced, leading to high maintenance and upkeep costs. In particular, since the punches are directly on the adjusting plate, the waste material generated during punching is difficult to remove in a timely manner, thus affecting the efficiency of the punching operation.

[0024] Please see Figure 1-9This utility model provides an embodiment of a punching machine, including a frame 1, with a punching assembly 3 inside the frame 1; the punching assembly 3 includes a fixing plate 32, a first adjusting assembly 36 on one side of the fixing plate 32, and a second adjusting assembly 37 on the other side of the fixing plate 32; the first adjusting assembly 36 and the second adjusting assembly 37 each include a first adjusting plate 33, a second adjusting plate 34, and a third adjusting plate 35; punches 313 are provided on the first adjusting plate 33, the second adjusting plate 34, and the third adjusting plate 35, and needle holders 311 are movably mounted on the first adjusting plate 33, the second adjusting plate 34, and the third adjusting plate 35; the needle holder 311 is also provided with a mounting hole 322; wherein, the mounting hole 322 is connected to a guide hole 319 provided on the needle holder 311, and the other end of the guide hole 319 completely penetrates the side of the needle holder 311, and waste material is led out through the guide hole 319.
[0025] In summary, since the needle holder 311 is movably mounted on each adjustment plate, it can be freely replaced when worn, effectively preventing the problem of punching quality being affected by enlarged punch holes. At the same time, the simple and convenient replacement of the needle holder 311 can reduce the maintenance cost of the equipment. In particular, the needle holder 311 is also provided with a guide hole 319 below it, so the punched waste material can flow out directly through the guide hole 319, which can improve the punching efficiency of the shoe upper.
[0026] In addition, since the end of the guide hole 319 away from the mounting hole 322 extends through the entire side of the needle seat 311, the waste material can be quickly discharged outward through the guide hole 319, thereby reducing the accumulation of waste material in the mounting hole 322.
[0027] Furthermore, since a support pad 321 is provided inside the mounting hole 322, the support pad 321 can directly contact the punch 313. Therefore, without replacing the needle holder 311, the maintenance cost of the equipment can be reduced by replacing the support pad 321 while ensuring normal punching. In addition, by replacing the support pad 321, the needle holder 311 can be adapted to punches 313 of different diameters. Based on this, the setting of the support pad 321 can further reduce the maintenance cost of the equipment.
[0028] To ensure that the support pad 321 is stably and reliably positioned within the mounting hole 322, a connecting hole 323 is provided radially in the mounting hole 322. A clamping rod 320 moves within the connecting hole 323 to fix the support pad 321 within the mounting hole 322. Preferably, the clamping rod 320 and the connecting hole 323 are threaded together. Therefore, tightening the clamping rod 320 prevents the support pad 321 from separating from the needle seat 311 when the punch 313 moves upward.
[0029] Based on the above scheme, the opening assembly 3 further includes a first drive shaft 30 and a second drive shaft 31; one end of the first drive shaft 30 passes through the frame 1 and is connected to the provided drive gear 2, and the other end of the first drive shaft 30 passes through the frame 1 and is exposed outside the frame 1; one end of the second drive shaft 31 passes through the frame 1 and is connected to the provided driven gear 4, and the driven gear 4 meshes with the drive gear 2. Therefore, by rotating one end of the first drive shaft 30, the drive gear 2 drives the driven gear 4 to rotate, thereby using the rotation of the two shafts to drive the movement of each adjusting plate; wherein, the transmission ratio between the drive gear 2 and the driven gear 4 is 2:1.
[0030] Specifically, the first adjusting plate 33, the second adjusting plate 34, and the third adjusting plate 35 are all equipped with linkage components 38. The second adjusting plate 34 is linked to the second drive shaft 31 via the linkage component 38, and the first adjusting plate 33 and the third adjusting plate 35 are also linked to the first drive shaft 30 via their own linkage components 38. Therefore, the two drive shafts cause each adjusting plate to move. The linkage component 38 includes a sliding block 318, and the sliding block 318 is equipped with a lead screw seat 314, which is fixed within the sliding block 318 by a set screw 316. The lead screw seat 314 and the corresponding drive shaft are connected by a lead screw drive.
[0031] Specifically, the first drive shaft 30 has a first threaded portion 324 and a second threaded portion 325 on one side, and a third threaded portion 326 and a fourth threaded portion 327 on the other side. The first threaded portion 324 and the fourth threaded portion 327, as well as the second threaded portion 325 and the third threaded portion 326, have the same structure except that the thread helix direction is opposite. The first threaded portion 324 is connected to the lead screw seat 314 on the third adjusting plate 35, and the second threaded portion 325 is connected to the lead screw seat 314 on the first adjusting plate 33.
[0032] The second drive shaft 31 has a fifth threaded section 328 on both sides. The two fifth threaded sections 328 are identical in structure except that the thread helix direction is opposite. The fifth threaded section 328 is connected to the lead screw seat 314 on the second adjusting plate 34.
[0033] Furthermore, since one end of the set screw 316 is connected to the groove 315 on the outer wall of the lead screw seat 314, and the other end of the set screw 316 is connected to the nut 317, the insertion of the set screw 316 into the groove 315 can effectively prevent the lead screw seat 314 from rotating within the corresponding adjustment plate, thus preventing power transmission failure. In addition, after the set screw 316 is tightened, the nut 317 is used to further lock the set screw 316 onto the sliding block 318.
[0034] Furthermore, to facilitate the smooth installation of each adjusting plate on the first drive shaft 30 or the second drive shaft 31, the sliding block 318 is slidably installed in the mounting groove 312 provided on the third adjusting plate 35. The third adjusting plate 35 is also provided with a fixing block 39 and a screw 310. After the fixing block 39 is fixed to the third adjusting plate 35, one end of the screw 310 passes through the fixing block 39 and abuts against the sliding block 318. Specifically, after the linkage 38 is installed into the mounting groove 312, the fixing block 39 is installed outside the mounting groove 312 to block the opening of the mounting groove 312. Then, the screw 310 is threaded into the screw hole in the middle of the fixing block 39. By rotating the screw 310, one end of the screw 310 is pressed against the sliding block 318 in the mounting groove 312.
[0035] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
