Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically a punching device for stainless steel sheet metal processing. Background Technology

[0002] Most equipment lacks a simple structure for limiting the position of sheet metal parts. When processing parallel holes in different locations on sheet metal parts, repositioning is required for effective punching. This is not only cumbersome and time-consuming, but also results in poor adaptability of the equipment to multi-hole sheet metal processing, making it difficult to quickly switch processing requirements. Therefore, those skilled in the art have provided a punching device for stainless steel sheet metal processing to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this utility model is to provide a punching device for stainless steel sheet metal processing to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A punching device for stainless steel sheet metal processing includes a base plate, a pair of bearing side plates fixedly connected to the upper surface of the base plate, a cylinder fixing plate fixedly connected between the bearing side plates, a punching cylinder provided on the cylinder fixing plate, a limit plate and a punching fixing plate also provided between the bearing side plates, and a punching component for punching is provided on the limit plate and the punching fixing plate.

[0005] Furthermore, the stamping assembly includes a reciprocating plate, a positioning rod, and a return spring. A set of positioning rods is fixedly connected to the upper surface of the limiting plate, and the reciprocating plate is slidably connected to the positioning rods. At the same time, a return spring is sleeved on the positioning rods, and the two ends of the return spring abut against the reciprocating plate and the limiting plate, respectively.

[0006] Furthermore, the stamping assembly also includes a force guide, a stamping sleeve, and a stamping head. The force guide is fixedly connected to the reciprocating plate and slidably connected to the limiting plate. The lower end of the force guide passes through the limiting plate, and the lower end of the force guide is threadedly connected to the stamping head. A stamping sleeve for use with the stamping head is fixedly connected to the stamping fixing plate.

[0007] Furthermore, a detection assembly is provided on the bearing side plate. The detection assembly includes a reset detector, a light shield, and a termination detector. The reset detector and the termination detector are fixedly connected to the surface of the bearing side plate and are vertically arranged. A light shield is fixedly connected to the upper surface of the reciprocating plate and is placed inside the detection end of the reset detector.

[0008] Furthermore, the bearing side plate is also provided with a limiting component, which includes an adjusting head, a receiving plate, a threaded rod and a threaded sleeve. The receiving plate is fixedly connected to the surface of the bearing side plate, and the threaded rod is rotatably connected to the receiving plate. One end of the threaded rod is fixedly connected to the adjusting head, and the surface of the threaded rod is threadedly connected to the threaded sleeve.

[0009] Furthermore, the limiting assembly also includes a limiting rod and a connecting block. The connecting block is fixedly connected to the surface of the threaded sleeve, and the limiting rod is fixedly connected to the surface of the bearing side plate. The lower end of the connecting block is slidably connected to the limiting rod through a sliding sleeve.

[0010] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: 1. The reset detector and termination detector on the bearing side plate work together with the light shield on the positioning rod to detect the movement status of the reciprocating plate in real time. When the light shield moves with the reciprocating plate, it can trigger the reset detector to confirm whether the reciprocating plate has returned to its initial position, avoiding deviation in the next stamping due to incomplete reset. The termination detector can accurately identify the downward limit of the stamping head, preventing excessive stamping from damaging the sheet metal, stamping head, or stamping cylinder. This automatic detection function reduces the cost of manual monitoring, avoids equipment failure and processing errors, ensures the consistency of processing quality, and extends the service life of the device. 2. In the stamping assembly, the positioning rod forms a sliding guide for the reciprocating plate. Combined with the sliding connection between the force guide and the limiting plate, it strictly limits the movement trajectory of the reciprocating plate and the stamping head, preventing lateral deviation during stamping, ensuring accurate punching positions, and reducing sheet metal scrap. The return spring, by abutting against the reciprocating plate and the limiting plate at both ends, automatically drives the reciprocating plate and the stamping head to return to their original positions after stamping, eliminating the need for manual operation, shortening the single processing cycle, and improving batch processing efficiency. The stamping head and the force guide are connected by threads, allowing for quick disassembly and replacement of stamping heads of different specifications. Simultaneously, with the matching stamping sleeve on the stamping fixing plate, it can meet the punching requirements of stainless steel sheet metal with different hole diameters and thicknesses, enhancing the flexibility of the device. 3. The limiting component rotates the threaded rod by rotating the adjusting head, causing the threaded sleeve to move along the threaded rod. With the sliding guide of the connecting block on the limiting rod, the limiting position can be precisely adjusted, enabling stainless steel sheet metal parts of different sizes to be quickly positioned to the expected size position. This improves the device's adaptability to sheet metal of various specifications and reduces equipment investment costs. Attached Figure Description

Then, a cylinder fixing plate 2, a limiting plate 8, and a stamping fixing plate 9 are fixed between the two bearing side plates 6. The cylinder fixing plate 2 is located on top, the limiting plate 8 is placed in the middle, and the stamping fixing plate 9 is located on the bottom. The three are kept parallel to provide stable support for the subsequent component installation. The stamping cylinder 1 is installed on the cylinder fixing plate 2, so that the output end of the stamping cylinder 1 faces the limiting plate 8, and the axis of the output end is aligned with the center area of ​​the stamping fixing plate 9, so that the driving force can act perpendicularly on the subsequent stamping components.

[0014] In this embodiment, the stamping assembly includes a reciprocating plate 4, positioning rods 5, and a return spring 7.

The press head 18 uses a stamping sleeve 17; a set of positioning rods 5 are vertically fixed on the upper surface of the limiting plate 8; the reciprocating plate 4 is slidably sleeved on the positioning rods 5, so that the reciprocating plate 4 can move up and down along the positioning rods 5; a return spring 7 is sleeved on the positioning rods 5, ensuring that one end of the return spring 7 abuts against the lower end face of the reciprocating plate 4 and the other end abuts against the upper end face of the limiting plate 8; a force guide 3 is fixed on the reciprocating plate 4, the force guide 3 passes through the limiting plate 8 and can move synchronously with the reciprocating plate 4, and the lower end of the force guide 3 is connected to the press head 18 by a thread; the stamping sleeve 17 is fixed on the stamping fixing plate 9 at the position corresponding to the press head 18, so that the press head 18 can accurately extend into the stamping sleeve 17 when it moves down.

[0015] In this embodiment, a detection assembly is provided on the bearing side plate 6. The detection assembly includes a reset detector 19, a light shield 20, and a termination detector 21. The reset detector 19 and the termination detector 21 are fixedly connected to the surface of the bearing side plate 6 and are vertically arranged. The light shield 20 is fixedly connected to the upper surface of the reciprocating plate 4 and is placed inside the detection end of the reset detector 19. The reset detector 19 and the termination detector 21 are fixedly fixed on the surface of the bearing side plate 6 and are vertically arranged. The reset detector 19 is located above, corresponding to the initial position of the reciprocating plate 4. The termination detector 21 is located below, corresponding to the downward limit position of the stamping head 18. The light shield 20 is fixed on the upper surface of the positioning rod 5 so that the light shield 20 can initially extend into the detection end of the reset detector 19. When the light shield 20 moves synchronously with the reciprocating plate 4, it can trigger the reset detector 19 and the termination detector 21 respectively. The device can be externally connected to a controller to adapt to the reset detector 19 and the termination detector 21.

[0016] In this embodiment, a limiting assembly is also provided on the bearing side plate 6. The limiting assembly includes an adjusting head 11, a receiving plate 12, a threaded rod 13, and a threaded sleeve 16. The receiving plate 12 is fixedly connected to the surface of the bearing side plate 6, and the threaded rod 13 is rotatably connected to the receiving plate 12. One end of the threaded rod 13 is fixedly connected to the adjusting head 11, and the threaded sleeve 16 is threadedly connected to the surface of the threaded rod 13. The limiting assembly also includes a limiting rod 14 and a connecting block 15. The connecting block 15 is fixedly connected to the surface of the threaded sleeve 16, and the limiting rod 14 is fixedly connected to the surface of the bearing side plate 6. The lower end of the connecting block 15 is slidably connected to the limiting rod 14 via a sliding sleeve. The receiving plate 12 is fixed on the surface of the bearing side plate 6. A threaded rod 13 is rotatably connected to the receiving plate 12, and the axis of the threaded rod 13 is perpendicular to the feeding direction of the sheet metal part. An adjusting head 11 is fixed at one end of the threaded rod 13 for easy manual rotation. A threaded sleeve 16 is threadedly connected to the surface of the threaded rod 13, and a connecting block 15 is fixed to the surface of the threaded sleeve 16. A limiting rod 14 is fixed to the surface of the bearing side plate 6, and the limiting rod 14 is parallel to the threaded rod 13. The lower end of the connecting block 15 is slidably connected to the limiting rod 14 through a sliding sleeve, so that the threaded sleeve 16 can move along the direction of the limiting rod 14 as the threaded rod 13 rotates. When the sheet metal is supplied, it can be laterally displaced through the through groove on the bearing side plate 6. The connecting block 15 can effectively limit the depth of the sheet metal.

[0017] Rotating the adjusting head 11 of the limiting assembly causes the threaded rod 13 to rotate, and the threaded sleeve 16 moves along the threaded rod 13. The connecting block 15 slides synchronously with the threaded sleeve 16 under the guidance of the limiting rod 14 until the connecting block 15 is adjusted to a position that matches the size of the sheet metal part to be processed. The stainless steel sheet metal part is then moved laterally into the pre-reserved slot of the bearing side plate 6, and the connecting block 15 restricts its depth, thus completing the positioning of the sheet metal part. After starting the device, the output end of the stamping cylinder 1 extends towards the limiting plate 8, pushing the guide component 3 to drive the reciprocating plate 4 to slide downward along the positioning rod 5 on the limiting plate 8. Consequently, the stamping head 18 at the lower end of the guide component 3 aligns with the sheet metal part, and the stamping head 18 continues to descend to punch holes in the sheet metal part. The stamping sleeve 17 on the stamping fixing plate 9 is adapted to receive the stamping head 18. During this process, the light-shielding plate 20 on the reciprocating plate 4 moves downward synchronously. When the punching head 18 reaches the downward limit position, the light-shielding plate 20 triggers the termination detector 21 on the bearing side plate 6. After receiving the signal, the external controller controls the punching cylinder 1 to stop moving downward to prevent excessive punching from damaging the parts. After punching is completed, the output end of the punching cylinder 1 retracts, and the return spring 7 on the positioning rod 5 releases the elastic force accumulated under pressure, pushing the reciprocating plate 4 to return upward along the positioning rod 5. The guide member 3 and the punching head 18 then return to their initial positions. At this time, the light-shielding plate 20 moves upward with the reciprocating plate 4, re-extends into the detection end of the reset detector 19 and triggers the instrument. After the controller confirms that the reset is in place, the processed sheet metal parts can be taken out, and new sheet metal parts can be placed in to repeat the above process to achieve batch processing.

[0018] The reset detector 19 and termination detector 21 on the bearing side plate 6 cooperate with the light shield 20 on the positioning rod 5 to detect the movement status of the reciprocating plate 4 in real time. When the light shield 20 moves with the reciprocating plate 4, it can trigger the reset detector 19 to confirm whether the reciprocating plate 4 has returned to its initial position, avoiding deviation in the next stamping due to incomplete reset. The termination detector 21 can accurately identify the downward limit of the stamping head 18, preventing excessive stamping from damaging the sheet metal, stamping head 18, or stamping cylinder 1. This automatic detection function reduces the cost of manual monitoring, avoids equipment failure and processing errors, ensures the consistency of processing quality, and extends the service life of the device. In the stamping assembly, the positioning rod 5 forms a sliding guide for the reciprocating plate 4. With the sliding connection between the force guide 3 and the limit plate 8, the movement trajectory of the reciprocating plate 4 and the stamping head 18 can be strictly limited to avoid lateral deviation during the stamping process, ensuring... Precise punching position reduces sheet metal scrap; the return spring 7, by abutting the reciprocating plate 4 and the limiting plate 8 at both ends, can automatically drive the reciprocating plate 4 and the punching head 18 to return to their original positions after punching, eliminating the need for manual operation, shortening the single processing cycle, and improving batch processing efficiency; the punching head 18 and the force guide 3 are connected by threads, allowing for quick disassembly and replacement of punching heads 18 of different specifications. Combined with the matching punching sleeve 17 on the punching fixing plate 9, it can meet the punching needs of stainless steel sheet metal with different hole diameters and thicknesses, enhancing the flexibility of the device; the limiting component rotates the adjusting head 11 to drive the threaded rod 13 to rotate, causing the threaded sleeve 16 to move along the threaded rod 13. With the sliding guide of the connecting block 15 on the limiting rod 14, the limiting position can be precisely adjusted, enabling stainless steel sheet metal parts of different sizes to be quickly positioned to the expected size, improving the device's adaptability to multiple sheet metal specifications and reducing equipment investment costs.

[0019] This specification describes embodiments, but not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
