[0003] The punching machine in the prior art, especially after stamping and bending the parts, generally clamps the workpiece on the lower die assembly, and then uses the upper die assembly to press down to stamp and bend the workpiece. After the stamping is completed, the stamped products need to be collected. The current operation method is conducive to the receiving tray, and the receiving tray is generally fixed on the side of the lower die. The stamped workpiece has a certain falling distance from the upper die to the receiving tray. The workpiece often falls to the outside of the receiving tray, resulting in manual operation in the later stage. The work efficiency is relatively low and there are also safety hazards.

[0022] like Figure 6 As shown, in order to achieve up and down and left and right movement, the upper die assembly 2 includes an upper die support 201, a linear module 1 202 extending along the X-axis, a linear module 2 203 extending along the Y-axis direction, and a stamping upper die set 204. The back of the linear module 1 202 is provided with a rear slide 205 slidably connected to the upper die support 201, the sliding seat of the linear module 1 202 is connected to the linear module 2 203, the sliding seat of the linear module 2 203 is fixed with a stamping support 207, the stamping support 207 is fixed with a stamping cylinder 206, the piston rod of the stamping cylinder 206 is connected to the stamping upper die set 204 (the stamping upper die set 204 belongs to the prior art and is not described in detail here), and an upper cylinder 208 connected to the rear slide 205 and driving the rear slide 205 to move up and down is fixed above the frame 1.

[0023] Preferably, in order to improve the strength of the push plate, the push plate 144 is an L-shaped structure, and one or more triangular fixing plates 34 are provided at intervals on the back of the push plate 144. The triangular fixing plates 34 are provided to further improve the overall strength of the push plate 144 and avoid its deformation.

[0024] Preferably, in order to realize automatic movement, guide sliders 35 slidably connected to the corresponding slide rails 11 are symmetrically arranged on both sides of the mobile bracket 12, and a pushing cylinder 2 36 for driving the mobile bracket 12 to move forward and backward is arranged at the rear of the storage channel 10. The pushing cylinder 2 36 is fixed on the frame 1, and the piston rod of the pushing cylinder 2 36 is connected to the rear of the mobile bracket 12. When working, the pushing cylinder 2 36 is driven to work, so as to push the mobile bracket 12 out of the storage channel 10, and finally realize automatic movement without manual operation.

[0025] Preferably, to improve safety, an infrared sensor alarm 37 electrically connected to the control cabinet 6 is provided on the side of the rack 1. By providing the infrared sensor alarm 37, an alarm reminder can be issued when a person approaches the equipment while the equipment is working.

[0026] The working principle of this structure is as follows: When the whole equipment is not in use, the whole pushing mechanism is stored in the storage channel 10, and a hidden structure is adopted so that it does not take up space and the volume of the whole equipment remains unchanged. At the same time, when the stamped workpiece needs to be unloaded quickly, the pushing cylinder 2 36 is driven to work, and the movable bracket 12 is pushed to move along the slide rail 11 to the front of the frame 1, and then the lifting cylinder 38 is driven to work to ensure that the lifting platform 13 is slowly lifted and first exceeds the table top above the frame 1, and then the pushing cylinder 2 36 is driven to retreat to ensure that the pushing channel 143 is located on the table top above the frame 1, so that the table top above the frame 1 can be stuck in the notch 33, until the infrared receiving sensor 902 and the infrared transmitting sensor 901 are blocked along the side of the lifting part 32, and the infrared receiving sensor 902 cannot receive the signal, and then the pushing cylinder 2 36 is driven to work. At this time, the pushing channel 143 is flush with the lower mold assembly 3, and then the workpiece is placed in the clamping channel 301, and the upper mold assembly 2 is driven to move downward. The workpiece is stamped and bent. After the operation is completed, the upper mold assembly 2 is reset and moved upward. At this time, the push cylinder 3 27 is driven to work, driving the push bar 28 to move forward and insert it into the guide groove 26 to form a guide slideway, and then the push cylinder 142 is driven to work, driving the push plate 144 to move along the guide slideway and insert it into the push channel 143, and then the front push rod 145 is inserted into each clamping channel 301 in turn, and the workpiece processed in the clamping channel 301 is accurately pushed into the rear discharge tray 8. The discharge tray 8 can be tilted to directly transport the workpiece to the receiving box placed at the rear of the frame 1. Therefore, this structural setting can achieve rapid material collection without manual operation, further improving work efficiency, and it is not easy to have the problem of workpiece falling when receiving the material during the material collection process. At the same time, when the entire structure is not in use, the push mechanism can be hidden to save space, and the entire structure is relatively lower in cost than using robots to receive materials, and the operation is relatively convenient, so rapid material unloading can be achieved. Example 2

[0027] See also Figure 8-11The embodiment discloses a high-precision and strong steel frame punch press. As a preferred embodiment, in order to realize the punching operation of the steel pipe in the later stage, a steel pipe clamping mechanism is arranged on the right side of the frame 1, and the steel pipe clamping mechanism includes a blowing support 16. The front end center of the blowing support 16 is connected with a blowing pipe 17 connected with the blowing support 16. The blowing pipe 17 is covered with blowing holes 18. The front end of the blowing support 16 is also annularly provided with three pneumatic clamps 19. The rear of the blowing support 16 is connected with a transmission main shaft 20, and the transmission main shaft 20 is movably plugged into a positioning support 21. The positioning support 21 is fixed on the frame 1. A driven gear 22 is fixed outside the rear of the transmission main shaft 20, and a transmission motor 23 is fixed on the positioning support 21. The output shaft of the transmission motor 23 is connected with a main transmission gear 24 that is transmission-connected to the driven gear 22. A synchronous transmission mechanism symmetrically arranged with the steel pipe clamping mechanism is arranged on the left side of the frame 1, and the synchronous transmission mechanism includes an air suction support 40, a suction pipe 401 is passed through the center of the suction support 40, and a pneumatic clamp seat 402 is also arranged at the front end of the suction support 40, the suction pipe 401 passes through the pneumatic clamp seat 402, and the pneumatic clamp seat 402 is rotatably connected to the outside of the suction pipe 401, and three pneumatic clamps 403 are arranged in a ring at the front end of the pneumatic clamp seat 402 (the structure of pneumatic clamp 203 is consistent with the structure of pneumatic clamp 19), the rear of the suction pipe 401 is connected to a vacuum cleaner 404 fixed under the suction support 40, and a debris collection box 101 is also pulled out and connected to the frame 1, and the other end of the vacuum cleaner 404 is connected to the debris collection box 101, and a transmission chain is arranged between the main drive gear 24 and the driven gear 22.

[0028] Preferably, in order to facilitate the replacement of processing tools, a stamping connecting seat 209 is fixed on the piston rod of the stamping cylinder 206, and the stamping connecting seat 209 is fixed to the stamping upper die set 204 by screws. The entire stamping upper die set 204 can be removed from the stamping connecting seat 209 at a later stage, and then other tools, such as existing punching needles or tapping tools or tapping tools, can be installed, and the punching needles or tapping tools or tapping tools can be fixed to the stamping connecting seat 209 by screws.

[0029] Through the structural setting of this embodiment, this structure can perform surface punching on the tubular body. When working, the upper stamping die set 204 is removed, and a punching needle or a tapping tool or a tapping tool is installed. Then the tubular body is inserted between the two steel pipe clamping mechanisms, and the pneumatic clamps 19 on both sides are used to clamp the tubular body. Then, the upper linear module 202 and the linear module 2 203 are driven to move to the position where holes need to be punched, and then the upper cylinder 208 is driven to work. The lower punch performs punching or tapping operations on the corresponding position of the tubular body. If multiple holes need to be set circumferentially, the main drive gear 24 can be driven to rotate by driving the transmission motor 23, and the driven gear 22 can be driven to rotate under the action of the transmission chain, and the blowing pipe 17 is driven to rotate synchronously, and the synchronous belt The pneumatic clamp seat 402 on the left side is rotated, which eventually causes the tubular body to rotate. In addition, an air blowing pipe 17 is arranged inside the right side of the structure, and an air hole 18 is blown to the through hole completed by punching or tapping. A gas generator is used to generate high-pressure gas, and then the debris remaining on the inner wall of the tubular body after drilling is blown to the left, and the debris is sucked in by the vacuum cleaner 404 and sent into the debris collection box 101. When the debris collection box 101 is full, the handle at the front end of the debris collection box 101 is used to pull out the entire debris collection box 101 to dump the debris. Therefore, the present structure can avoid the problem of debris remaining in the tubular body and needing to be cleaned up later (and it should be noted that the air blowing method of the present structure only acts on the state when the wall of the tubular body needs to be pierced).

A sliding block 405 slidably connected to the slide 103 is arranged at the bottom of the pneumatic clamp seat 402. When the pneumatic clamp seat 402 moves, the distance between the steel pipe clamping mechanism and the synchronous transmission mechanism can be changed. When working, the pneumatic clamp seat 402 is driven to move along the slide 103 by driving the push cylinder four 102 to change the distance between the steel pipe clamping mechanism and the synchronous transmission mechanism, so that it can clamp pipes of different lengths, further improving the versatility. In order to ensure that the connectivity between the other end of the vacuum cleaner 404 and the debris collection box 101 is not affected when the pneumatic clamp seat 402 moves, the pipe connecting the vacuum cleaner 404 and the debris collection box 101 adopts a soft, foldable and stretchable hose.
