Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, and in particular to a sheet metal punching device and punching method. Background Technology

[0002] In the sheet metal processing, punching and grinding are key processes that directly affect the product's precision and surface quality.

[0003] Traditional processing equipment often employs a separate design for punching and grinding, requiring sheet metal parts to be transferred between different machines. This not only increases transportation and time costs but also easily leads to positioning deviations due to secondary clamping, affecting processing accuracy. Furthermore, traditional grinding equipment lacks flexibility in adjusting grinding force and precision, often operating with fixed parameters, making it difficult to adapt to the diverse grinding needs of sheet metal parts of different thicknesses and materials. This can easily result in over-grinding or incomplete grinding. In addition, traditional equipment generates a large amount of metal shavings during grinding, lacking an efficient synchronous collection mechanism. Scattered shavings not only pollute the working environment but may also affect the normal operation of the equipment, increasing the manpower required for subsequent cleaning. Although some equipment is equipped with simple dust removal devices, the collection efficiency is low, making it impossible to achieve centralized recycling of shavings. Summary of the Invention

Sheet metal parts are conveyed by a conveyor belt, and after being limited by double and single rollers, they are polished by the grinding assembly. The distance between the upper and lower rollers is adjusted by a hydraulic cylinder to achieve the appropriate grinding precision. During the polishing process, the scraper intercepts surface debris, and the fan blows the debris toward the filter screen. After being blocked by the outer frame, the debris falls into the collection box, achieving unified collection of debris.

[0006] The present invention has the following beneficial effects: 1. In this invention, the punching mechanism, base, adjustable grinding mechanism and conveyor belt work together to alleviate the problems of traditional processing equipment which often adopts a separate design for punching and grinding, requiring sheet metal parts to be transferred between different equipment. This not only increases transportation and time costs, but also easily leads to positioning deviations due to secondary clamping, affecting processing accuracy. At the same time, traditional grinding equipment lacks flexibility in adjusting grinding force and precision, and mostly operates with fixed parameters, making it difficult to adapt to the diverse grinding needs of sheet metal parts of different thicknesses and materials, and easily causing problems of over-grinding or incomplete grinding.

[0007] 2. In this invention, by coordinating the driving cleaning mechanism, cover frame, air filter plate, outer frame, filter screen and collection box, the problem of traditional equipment generating a large amount of metal shavings during the grinding process and lacking an efficient synchronous collection mechanism is alleviated. The shavings not only pollute the working environment, but may also affect the normal operation of the equipment and increase the manpower consumption for subsequent cleaning. Although some equipment is equipped with simple dust removal devices, the collection efficiency is low and the problem of centralized recycling of shavings cannot be achieved.

When the sheet metal parts to be ground are driven on the conveyor belt 10, they are pressed by the double rollers 26 and the single rollers 27, which facilitates grinding. The double rollers 26 and the single rollers 27 will not affect the transmission of the sheet metal parts to be ground. The punching mechanism 9 includes two connecting plates 91 fixedly connected to the middle left side of the front and rear ends of the main frame 21, and a bearing frame 94 fixedly connected to the lower sides of the two connecting plates 91 at the ends away from the main frame 21.

[0012] The clamping mechanism 95 includes two loading boxes 951, a main motor 952, and two bidirectional threaded rods 953. The two loading boxes 951 are respectively fixed to the inner walls of the left and right ends of the lower part of the support frame 94. One of the bidirectional threaded rods 953 is fixed to the right output end of the main motor 952. Threaded sleeves 955 are threaded to the outer circumference of both ends of the bidirectional threaded rod 953.

At the same time, the left output end is linked to another bidirectional threaded rod 953 through pulley 958, synchronous belt 9510 and pulley 959 to rotate synchronously. The threaded sleeves 955 on the two bidirectional threaded rods 953 drive the clamping plate 957 to move relative to each other, and smoothly clamp the sheet metal part to ensure no displacement deviation during punching. Then, the position of the punch head is adjusted and the punching operation is performed. The auxiliary motor 96 is started to drive... The first moving screw 97 rotates, driving the main slide plate 98 to move horizontally and adjusting the lateral position of the punch head 914; the motor 910 is started, driving the second screw 911 to rotate, driving the auxiliary slide plate 912 to move horizontally and adjusting the longitudinal position of the punch head 914. After the punching position is accurately positioned by adjusting in both directions, the telescopic rod 913 extends, driving the punch head 914 to move downward to complete the punching. Then, it is automatically conveyed and flipped. After the punching is completed, the clamping plate 957 moves in the opposite direction to release the sheet metal part. The sheet metal part falls into the transmission belt 92 and is conveyed to the flipping guide plate 93 by the transmission belt 92.

A support positioning wheel 2534 is rotatably connected to the end of the rotating rod 2532 near the connecting plate 2531. A fixing plate 2538 is fixedly connected to the lower end of the side of the connecting plate 2531 away from the lower roller 2533. A slot 25 is provided in the middle of the front end of the fixing plate 2538. 39. A support rod 2536 is provided in the middle of the slot 2539. The lower end of the support rod 2536 is fixedly connected to the middle of the front side of the main frame 21.

The end of the connecting rod 2535 away from the support positioning wheel 2534 is rotatably connected to the connecting plate 2531. Before grinding, on the side of the upper section away from the support frame 2521, adjust according to the plane inclination of the sheet metal part to be ground. Rotate the rotating block 2537 outward so that the lifting end of the rotating block 2537 disengages from the support positioning wheel 2534, so that the outer wall of the lower roller 2533 fits against the surface of the sheet metal part to be ground. Tighten the threaded lock on the support rod 2536 to adjust the height of the support rod 2536. After reaching the appropriate height, rotate the rotating block 2537 back to its original position so that the rotating block 2537 is once again engaged with the support positioning wheel 2534. On the lower side, the lower roller 2533 rotates more stably. The connecting rod 2535 pushes the support positioning wheel 2534, making the support positioning wheel 2534 and the rotating block 2537 engage more tightly, making the subsequent equipment operation more stable. At the same time, the upper roller 2547 is adjusted according to the level of the lower roller 2533. The threaded lock on the slot 2545 is turned to adjust the height of the two rotating blocks 2546, so that the upper roller 2547 and the lower roller 2533 remain parallel, which facilitates the operation of the subsequent equipment.

[0015] Two grinding components 25 are positioned between two double-roller rollers 26, and two single-roller rollers 27 are positioned between two grinding components 25. Two electromagnetic actuators 2522 are respectively positioned on the upper left and right sides of the support frame 2521. The anti-folding roller 2523 and the lower roller 2533 are both positioned below the support frame 2521. The outer side of the lower roller 2533 is connected to the outer side of the upper roller 2547 via an elastic abrasive cloth 251. The hydraulic cylinder 2541 is activated to adjust the distance between the upper roller 2547 and the lower roller 2533 according to the required grinding precision. This allows for fine adjustment of the tension of the elastic abrasive cloth 251, thereby adjusting the grinding speed and force. This allows the equipment to be adjusted according to different grinding precision requirements. During the grinding process, the two edges of the elastic abrasive cloth 251 are positioned in the middle of the anti-folding roller 2523, which prevents the elastic abrasive cloth 251 from loosening and folding, thus affecting the grinding effect.

[0016] The upper grinding component 254 includes a hydraulic cylinder 2541 fixedly connected to the upper side of the middle of the support frame 2521, a support plate 2542 fixedly connected to the end of the hydraulic cylinder 2541 away from the support frame 2521, and two fixing plates 2544 respectively fixedly connected to the upper sides of the front and rear ends of the support plate 2542. The lower ends of the two fixing plates 2544 on the opposite sides are fixedly connected to rotating blocks 2546. An upper roller 2547 is rotatably connected between the top ends of the two rotating blocks 2546. The upper middle section of each of the two fixed plates 2544 is provided with a slot 2545. The tops of the two rotating blocks 2546 are respectively located in the middle of the two slots 2545. The upper roller 2547 is located between the two fixed plates 2544. A fixed rod 2543 is fixedly connected to the lower side of the support plate 2542. The position of the fixed rod 2543 corresponds to the position of the electric clamp 2526. The end of the fixed rod 2543 away from the support plate 2542 is located in the middle of the electric clamp 2526.

[0017] The chip scraper assembly 22 includes a top plate 221 fixedly connected to the upper inner wall of the main frame 21, two chip scrapers 223 both disposed on the lower side of the top plate 221, and two connecting strips 226 fixedly connected to the middle right side of the two chip scrapers 223 respectively. Connecting strips 225 are fixedly connected to the middle front and rear sides of the two chip scrapers 223. The lower side of the top plate 221 is connected to the two connecting strips 226 respectively via two connecting strips 222, and the lower side of the top plate 221 is connected to the connecting strips 225 respectively via multiple connecting strips 224. The two chip scrapers 223 are respectively disposed on the lower side of the main frame 21. On the right side of the grinding assembly 25, the scraper 223, the double roller 26, and the single roller 27 are all located on the upper side of the conveyor belt 10. Rotate the folding bar 2528 so that it is parallel to the upper roller 2547 and the lower roller 2533, so that the surfaces of the two rollers 2529 are in contact with the inner wall of the elastic abrasive cloth 251, so that the elastic abrasive cloth 251 remains unfolded during operation, further reducing the probability of the elastic abrasive cloth 251 curling up. The height of the scraper 223 is adjusted by adjusting the connection point between the connecting bar 1 222 and the connecting bar 4 226 and the connection point between the connecting bar 224 and the connecting bar 3 225.

The end of each connecting cylinder 327 away from the grinding assembly 25 is rotatably connected to a second wheel 324.

[0019] The section of the rotating rod 2532 away from the connecting plate 2531 is located in the middle of the connecting cylinder 327.

A filter screen 7 is fixedly connected to the inner wall of the front side of the outer frame 6. A collection box 8 is provided on the lower side of the outer frame 6.

[0020] Through the coordinated operation of various mechanisms, the grinding, punching and debris collection of sheet metal parts can be integrated to meet the processing needs of different precision. After the equipment is started, the sheet metal parts to be punched are placed into the punching mechanism 9. The main motor 952 drives the bidirectional threaded rod 953 to drive the clamping plate 957 to clamp the sheet metal parts. The auxiliary motor 96 and the motor 910 work together to adjust the position of the punching head 914. The telescopic rod 913 drives the punching head 914 to complete the punching. After that, the clamping plate 957 releases the sheet metal parts. The sheet metal parts are transmitted through the transmission belt 92, flipped over by the flipping guide plate 93, and then smoothly guided onto the conveyor belt 10. The motor 321 serves as the core power source, driving the grinding component 25 to operate and driving the fan 326 to blow air, forming a power transmission system that synchronizes grinding and debris collection, ensuring that each functional module responds synchronously. Sheet metal parts are conveyed by conveyor belt 10, and after being limited by double rotating roller 26 and single rotating roller 27, they are polished by grinding assembly 25. The distance between upper roller 2547 and lower roller 2533 is adjusted by hydraulic cylinder 2541 to achieve grinding accuracy matching. During the grinding process, the scraper 223 intercepts surface debris, and the fan 326 blows the debris toward the filter screen 7. After being blocked by the outer frame 6, the debris falls into the collection box 8, achieving unified collection of debris. The bottom of the scraper 223 matches the sheet metal part to be ground, which facilitates the interception and scraping of the debris generated during subsequent transmission grinding. Then, the two motors 321 are started to drive the first rotating wheel 322 to rotate. As the first synchronous belt 325 and the second rotating wheel 324 drive the rotating rod 2532 and the fan 326 to rotate, it can not only drive the grinding assembly 25 to work, but also make the fan 326 blow air onto the grinding assembly 25 and the conveyor belt 10. This causes the debris generated during transmission grinding intercepted by the scraper 223 to be blown onto the outer frame 6 by the air, and then fall into the collection box 8 under the obstruction of the outer frame 6 for unified collection. This allows the equipment to be better adjusted according to different grinding precision requirements when grinding sheet metal parts.

[0021] Working Principle: This device integrates punching, conveying, grinding, and chip collection to achieve high-precision processing and efficient cleaning of sheet metal parts. The core processes revolve around precise punching, flexible grinding, and synchronous chip collection. The equipment features precise punching and automatic conveying. First, the sheet metal part is clamped and fixed in place. The sheet metal part to be processed is placed into the bearing frame 94 of the punching mechanism 9. The main motor 952 is started, and its right output end drives a bidirectional threaded rod 953 to rotate. Simultaneously, the left output end, through pulley 958, synchronous belt 9510, and pulley 959, links another bidirectional threaded rod 953 to rotate synchronously. The threaded sleeves 955 on the two bidirectional threaded rods 953 drive the clamping plates 957 to move relative to each other, smoothly clamping the sheet metal part and ensuring... There is no displacement deviation during the punching process. Afterwards, the punch head position is adjusted and the punching operation is performed. The auxiliary motor 96 is started, driving the lead screw 97 to rotate, which moves the main slide plate 98 horizontally to adjust the lateral position of the punch head 914. The motor 910 is started, driving the lead screw 911 to rotate, which moves the auxiliary slide plate 912 horizontally to adjust the longitudinal position of the punch head 914. After precise positioning of the punching position in both directions, the telescopic rod 913 extends, driving the punch head 914 downward to complete the punching. Then, automatic conveying and flipping are performed. After punching, the clamping plate 957 moves in the opposite direction to release the sheet metal part, which falls into the transmission belt 92 and is conveyed to the flipping guide plate 93. After flipping by the flipping guide plate 93, it is smoothly guided onto the conveyor belt. 10. Proceed to the subsequent grinding process to achieve a seamless connection between punching and grinding. The sheet metal part to be ground is then transported from the upper left side of conveyor belt 10 to the upper right side. While being transported on conveyor belt 10, the sheet metal part is pressed down by the double rotating roller 26 and the single rotating roller 27, facilitating grinding. The double rotating roller 26 and the single rotating roller 27 do not interfere with the transmission of the sheet metal part. Before grinding, the inclination of the sheet metal part is adjusted according to its planar tilt. The rotating support block 2537 is rotated outwards, causing its lifting end to disengage from the support positioning wheel 2534, so that the outer wall of the lower roller 2533 fits against the surface of the sheet metal part to be ground. The threaded lock on the support rod 2536 is turned to adjust the height of the support rod 2536. After reaching the appropriate height, the rotating support block 2537 is rotated back to its original position, allowing it to once again engage with the underside of the support positioning wheel 2534. This ensures more stable rotation of the lower roller 2533. The connecting rod 2535 pushes against the support positioning wheel 2534, further tightening the engagement between the support positioning wheel 2534 and the rotating support block 2537, resulting in more stable operation of the equipment. Simultaneously, the upper roller 2547 is adjusted based on the levelness of the lower roller 2533. The threaded locks on the slot 2545 are tightened to adjust the height of the two rotating blocks 2546, ensuring the upper roller 2547 is parallel to the lower roller 2533 for easier operation. Finally, the hydraulic cylinder 2541 is activated for further adjustment based on the required grinding precision.This allows the distance between the upper roller 2547 and the lower roller 2533 to be shortened or increased, thereby enabling fine-tuning of the tension of the elastic abrasive cloth 251, and consequently adjusting the grinding speed and force. This allows the equipment to be adjusted according to different grinding precision requirements. During grinding, the two edges of the elastic abrasive cloth 251 are positioned in the middle of the anti-folding roller 2523, preventing the elastic abrasive cloth 251 from loosening and curling, which would affect the grinding effect. Simultaneously, rotating the folding strip 2528 parallels the upper roller 2547 and the lower roller 2533, causing the surfaces of the two rollers 2529 to adhere to the inner wall of the elastic abrasive cloth 251, keeping the elastic abrasive cloth 251 unfolded during operation, further reducing the probability of curling. By adjusting the connection points of connecting strip 1 222 and connecting strip 4 226, and connecting strip 2 224 and connecting strip 3 225, the height of the scraper plate 223 is adjusted, ensuring the bottom of the scraper plate 223 is within the correct range. Matched to the sheet metal parts to be ground, this facilitates the interception and scraping of grinding debris during the subsequent grinding process. Two motors 321 are then activated, driving the first rotating wheel 322 to rotate. This, in turn, drives the rotating rod 2532 and fan 326 via the first synchronous belt 325 and the second rotating wheel 324. This not only drives the grinding assembly 25 but also allows the fan 326 to blow air onto the grinding assembly 25 and the conveyor belt 10. The debris intercepted by the scraper 223 during the grinding process is then blown onto the outer frame 6 and falls into the collection box 8 for unified collection. This allows the equipment to be better adjusted according to different grinding precision requirements when grinding sheet metal parts, reducing limitations in grinding precision and resulting in more ideal grinding accuracy. Furthermore, the collection of grinding debris during grinding facilitates subsequent unified processing, making cleaning more convenient and reducing manual labor costs.
