Description

Technical Field

[0001] The present invention belongs to the technical field of automobile seat production, and specifically relates to a precise punching device for ventilation holes in automobile seat leather. Background Art

[0002] During the manufacturing process of automobile seats, the air permeability of leather materials is an important performance index. To improve the comfort and aesthetics of the seats, a large number of ventilation holes usually need to be processed on the leather surface. Currently, the punching process for automobile seat leather mainly relies on automated or semi-automated punching devices.

[0003] For example, the utility model with the publication number CN218202885U discloses a punching device for automobile seat leather covers, which includes a support frame body. A transverse movement mechanism, a longitudinal movement mechanism, a punching mechanism, a backing plate, a locking nut, and a control mechanism are provided on the support frame body. The longitudinal movement mechanism is used to drive the transverse movement mechanism to move, the transverse movement mechanism is used to drive the punching mechanism to move. The backing plate is located below the punching mechanism and one end is fixedly connected to the support frame body. The other end of the backing plate is connected to a lead screw. A support rod is rotatably connected to the support frame body. The support rod, the locking nut, and the lead screw are used in cooperation. The lower part of the backing plate is hollow, and the control mechanism is used to control the transverse movement mechanism, the longitudinal movement mechanism, and the punching mechanism. Beneficial effects: There is no need to disassemble the seat leather cover, and the punching is non-destructive, with high punching efficiency.

[0004] However, in the actual production process, a large amount of leather debris will be generated during the punching operation. Conventional punching devices usually lack an efficient dust removal system, resulting in the accumulation of debris on the leather surface or around the equipment. It is easy to enter the moving parts of the equipment (such as guide rails, bearings, etc.), leading to increased equipment wear, reduced service life of the equipment, affecting punching accuracy and product quality. At the same time, the debris spreads in the air, posing a threat to the health of operators and increasing the workload of cleaning and maintenance.

[0005] Therefore, a precise punching device for ventilation holes in automobile seat leather is proposed to solve the problems raised in the background art. Summary of the Invention

It further includes:

[0009] A dust suction mechanism, which is located on the mounting base and is used to adsorb impurities generated by drilling;

[0010] Wherein, the dust suction mechanism includes a dust-proof cover, a corrugated pipe inserted at the top of the dust-proof cover, an air pump arranged at one end of the corrugated pipe away from the dust-proof cover, and a discharge pipe fixedly arranged at the bottom of the air pump;

[0017] Preferably, a connecting rod is fixedly arranged at the bottom of one side of the fixing plate away from the spring, a rotating block is fixedly connected to the bottom of the connecting rod, and the rotating block is rotatably connected to the top of the dust-proof cover and the side wall of the collection box.

[0018] Preferably, two groups of symmetric circular ring grooves are formed on the top of the dust-proof cover and the side wall of the collection box, circular ring blocks are rotatably clamped inside the circular ring grooves, and the circular ring blocks are fixedly connected to the rotating blocks.

[0019] Preferably, the drilling mechanism includes an electric cylinder fixedly installed at the bottom of the top plate, a drilling die arranged at the bottom of the electric cylinder, a drill bit fixedly arranged at the bottom of the drilling die, and a disassembly and assembly component arranged on the dust-proof cover for replacing the drilling die.

[0020] Preferably, the disassembly and assembly component includes clamping plates symmetrically arranged on two symmetrical sides of the punching die, two racks fixedly arranged on the tops of the clamping plates, trapezoidal sliders fixedly arranged on the tops of the racks and slidably connected with trapezoidal chutes, a gear rotatably arranged on the top of the dust cover and meshed with the rack, and a motor fixedly arranged on the top of the dust cover for driving the gear to rotate.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] Through the cooperation of structures such as the dust cover, bellows, and air pump, the present invention facilitates the rapid cleaning of the mechanical energy of leather debris generated by punching. Through the dust suction mechanism, the air pump drives the bellows to adsorb the debris in the dust cover, and the debris is transported to the collection box through the discharge pipe. The debris falls into the pull-out box under the action of gravity, and the pull-out box can be manually pulled out to clean the debris after use, solving the problem that the existing punching device is not convenient for quickly collecting debris, easily causing damage to the device, and affecting the punching efficiency.

[0023] Through the cooperation of structures such as the limiting circular plate, spring, and clamping block, the present invention facilitates the rapid replacement of the bellows. The replacement component is manually operated for replacement. The clamping block is moved upward to contract, driving the clamping block to disengage from the clamping groove. At this time, the spring is in a compressed state. Then, the fixing plate is rotated to make the circular ring block rotate, realizing the separation of the limiting circular plate from the dust cover and the collection box. After removing the old bellows, a new bellows is installed and both ends are inserted. The clamping block is rotated and the spring is used to achieve rapid fixation to complete the replacement.

[0024] Through the cooperation of structures such as the electric cylinder, punching die, and disassembly and assembly component, the present invention facilitates adapting to the punching requirements of different specifications of leather and realizing diversified punching. The punching mechanism is used for rapid punching. The punching die can be replaced by using the disassembly and assembly component according to requirements. The motor drives the gear to rotate, driving the rack to move, making the trapezoidal slider slide in the trapezoidal chute, so that the clamping plates are separated, facilitating the removal and replacement of the punching die. After replacement, the motor rotates in reverse to make the clamping plates clamp and fix again. Subsequently, the electric cylinder drives the dust suction mechanism and the punching die to descend, and rapid batch punching is achieved through the punching head.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figures 1 to 8 shown, the present invention provides a precise punching device for air holes in automotive seat leather, including a bottom plate 1, a mounting seat 11 fixedly installed on the top of the bottom plate 1, a top plate 12 fixedly arranged on the top of the mounting seat 11, and a punching mechanism 2 located at the bottom of the top plate 12. It further includes:

[0036] A working panel 3, the side of the bottom plate 1 is provided with placing grooves 13 linearly arranged in an array on both sides, and the working panel 3 is slidably inserted into the interior of the placing grooves 13;

[0037] The dust suction mechanism 4 is located on the mounting base 11 and is used to adsorb the impurities generated by punching; the dust suction mechanism 4 includes a dust-proof cover 41, a corrugated pipe 42 inserted into the top of the dust-proof cover 41, an air pump 43 arranged at one end of the corrugated pipe 42 away from the dust-proof cover 41, and a discharge pipe 431 fixedly arranged at the bottom of the air pump 43;

[0038] On one side of the mounting base 11 away from the punching mechanism 2, a collection box 44 is fixedly arranged. The air pump 43 is fixedly connected to the top of the collection box 44. A notch 441 is formed on one side of the collection box 44 away from the mounting base 11. A pull-out box 45 is slidably arranged inside the notch 441. A sealing gasket 411 is fixedly arranged at the bottom of the dust-proof cover 41. Trapezoidal sliding grooves 412 are formed on both sides of the top of the dust-proof cover 41 symmetrically. One end of the corrugated pipe 42 away from the dust-proof cover 41 penetrates through the side surface of the collection box 44 and is inserted into the interface of the air pump 43.

[0039] Adopting the above scheme: When using this device, first place the seat leather to be punched flat on the working panel 3 and fix it through the fixing device to ensure the accuracy and stability during the punching process. Then start the punching mechanism 2 to drive the punching die 22 to descend and perform a fast and efficient punching operation on the seat leather. During the punching process, due to the characteristics of the leather material, a large amount of debris will inevitably be generated. If these debris remain on the working panel 3, it will not only affect the accuracy of subsequent punching operations but also may cause wear to the mechanical equipment and reduce its service life. To solve this problem, the device is equipped with an efficient dust suction mechanism 4. This mechanism drives the corrugated pipe 42 to operate through the air pump 43, quickly adsorbing the leather debris and impurities generated inside the dust-proof cover 41. The adsorbed debris will be transported to the collection box 44 through the discharge pipe 431. Inside the collection box 44, the debris naturally settles under the action of gravity and finally falls into the pull-out box 45. This design not only realizes the rapid cleaning of debris but also ensures the cleanliness of the working environment and avoids the impact of debris on the equipment and operators. When the punching operation is completed, the operator can manually pull out the pull-out box 45 from the collection box 44 to uniformly clean and dump the accumulated debris inside.

[0040] As Figure 6 shown, replacement components 46 are arranged at the joints of the corrugated pipe 42 with the dust-proof cover 41 and the collection box 44. The replacement components 46 are used to replace the corrugated pipe 42;

[0041] The replacement component 46 includes a limiting circular plate 461 fixedly arranged on the outer walls of both ends of the corrugated pipe 42 near the dust cover 41 and the collection box 44, clamping grooves 462 opened on the symmetric two sides of the limiting circular plate 461, a clamping block 463 slidably inserted inside the clamping grooves 462, a spring 466 fixedly arranged on the top of the clamping block 463, and a fixing plate 465 fixedly installed on the top of the spring 466. At the bottom of the side of the fixing plate 465 away from the spring 466, a connecting rod 464 is fixedly arranged. The bottom of the connecting rod 464 is fixedly connected with a rotating block 467. The rotating block 467 is rotationally connected with the top of the dust cover 41 and the side wall of the collection box 44. On the top of the dust cover 41 and the side wall of the collection box 44, two groups of symmetric circular ring grooves 468 are opened. Inside the circular ring grooves 468, a circular ring block 469 is rotationally clamped. The circular ring block 469 is fixedly connected with the rotating block 467.

[0042] Adopting the above scheme: The quick disassembly and assembly of the corrugated pipe 42 are realized by using the replacement component 46. Since the corrugated pipe 42 is in a state of continuous stretching and contraction during punching after long-term use, it is easy to cause the pipe to break. The corrugated pipe 42 can be quickly replaced by using the replacement component 46. Specifically, by manually moving the clamping block 463 upward, the bottom clamping block 463 is driven to move out of the clamping groove 462, so that the spring 466 is in a compressed state. At this time, the fixing plate 465 is rotated to drive the bottom rotating block 467 to rotate synchronously, so that the circular ring block 469 rotates 180 degrees in the circular ring groove 468. At this time, the clamping block 463 can be made to be away from the clamping groove 462, thus realizing the quick separation of the limiting circular plate 461 from the dust cover 41 and the collection box 44, facilitating the removal of the corrugated pipe 42. After replacing the new corrugated pipe 42, its two ends are respectively inserted into the dust cover 41 and the collection box 44. By manually rotating the clamping block 463 to one side of the clamping block 463, quick fixed insertion is realized simultaneously under the reset action of the spring 466, thereby realizing the quick replacement of the corrugated pipe 42.

[0043] As Figures 7 to 8 shown, the punching mechanism 2 includes an electric cylinder 21 fixedly installed at the bottom of the top plate 12, a punching die 22 arranged at the bottom of the electric cylinder 21, a punching head 221 fixedly arranged at the bottom of the punching die 22, and a disassembly and assembly component 23 arranged on the dust cover 41 for replacing the punching die 22;

[0044] The disassembly and assembly component 23 includes clamping plates 231 symmetrically arranged on two symmetric sides of the punching die 22, two racks 232 fixedly arranged on the tops of the clamping plates 231, trapezoidal sliders 2321 fixedly arranged on the tops of the racks 232 and slidably connected with the trapezoidal chute 412, a gear 233 rotatably arranged on the top of the dust cover 41 and meshed with the rack 232, and a motor 234 fixedly arranged on the top of the dust cover 41 for driving the gear 233 to rotate. The outside of the motor 234 is covered with a connecting cover 235, and the bottom and the top of the connecting cover 235 are fixedly connected with the dust cover 41 and the electric cylinder 21 respectively.

[0045] Adopting the above solution: The punching mechanism 2 is used to achieve rapid punching. During the punching process, in order to adapt to different punching adjustments, the punching die 22 can be replaced by using the disassembly and assembly component 23 according to the required punching situation. The motor 234 is used to drive the gear 233 to rotate, thereby driving the two racks 232 on both sides to move away from each other, so that the trapezoidal slider 2321 moves in the trapezoidal chute 412, and then drives the two clamping plates 231 to move away from each other, facilitating the separation of the punching die 22 from the dust cover 41 and taking it out for replacement. After replacement, the motor 234 is reversed to drive the gear 233 to move closer to each other, so that the clamping plates 231 clamp and fix it. After fixing, the electric cylinder 21 is used to drive the entire dust suction mechanism 4 and the punching die 22 to descend, and rapid batch punching is achieved through the punching head 221.

[0046] Working principle and usage process of the present invention: When using this device for punching operations, first, according to specific punching requirements, the disassembly and assembly component 23 is used to quickly replace the punching die 22 to ensure that the punching size and shape meet the requirements. Subsequently, the electric cylinder 21 is started to drive the dust-proof cover 41 and the replaced punching die 22 to descend synchronously, and efficient and precise punching processing is carried out on the seat leather placed on the working panel 3. During the punching process, in order to prevent the punching head 221 from damaging the surface of the working panel 3 due to long-term use or improper operation, resulting in unevenness and affecting the subsequent punching quality, the operator can remove and replace the punching head 221 along the placement groove 13, thereby ensuring the stability of the punching process and the processing effect. To further improve the cleanliness of the punching environment, the sealing gasket 411 at the bottom of the dust-proof cover 41 will closely fit with the working panel 3 during operation to form a completely sealed punching space. This design not only effectively prevents the scattered debris generated during punching, avoids the pollution of the operation environment and engineering equipment by the debris, but also ensures the physical health and work safety of the operator. At the same time, by starting the air pump 43 through the control panel 14, the corrugated pipe 42 inside the dust-proof cover 41 will start to operate, and efficiently adsorb the debris generated during punching. The adsorbed debris will be transported through the discharge pipe 431 to the drawer box 45 in the collection box 44 to achieve the unified collection and centralized treatment of the debris, which is not only convenient for the subsequent cleaning and reuse of the debris, but also greatly improves the work efficiency. In addition, a replacement component 46 is also equipped for the regular replacement or maintenance of the corrugated pipe 42. Since the corrugated pipe 42 may be worn or damaged after long-term use, affecting its dust suction effect, the corrugated pipe 42 can be quickly replaced through the replacement component 46 to ensure the continuous and efficient operation of the dust suction system, thereby ensuring the cleanliness and stability of the entire punching process. This modular design not only improves the maintainability of the equipment, but also extends the service life of the device and reduces the maintenance cost.
