Description

Technical Field

[0001] The present invention belongs to the technical field of punching devices, and more specifically, relates to a punching device for processing stainless steel strips. Background Art

[0002] Stainless steel strip is a metal strip material with high strength, corrosion resistance and aesthetics. It is widely used in machinery manufacturing, electronics, construction, medical equipment, aerospace and other fields.

[0003] Use hydraulic or pneumatic clamps to clamp the steel strip to prevent the material from sliding or vibrating during punching. During the processing, coolant must be continuously injected to reduce the tool temperature and flush the iron chips to prevent tool annealing and overheating deformation of the steel strip. First, drill a small positioning hole, then expand the hole to the designed size to reduce the deviation of large-diameter one-time forming. During the punching process, there are the following deficiencies;

[0004] 1. Stainless steel is prone to work hardening during the cutting process, producing finer chips or strip-shaped chips. The attached chips may be stuck between the hole wall and the drill bit, causing the drill bit to deviate or vibrate during the drilling process, resulting in an out-of-tolerance hole size.

[0005] 2. Through the reciprocating motion of the punching assembly, holes are continuously punched on the surface of the stainless steel belt. The movement frequency of the stainless steel belt and the punching assembly must match. During the punching process, if the initial position is punched incorrectly, it will cause subsequent position synchronization deviations, resulting in material waste. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a punching device for stainless steel strip processing to solve the above problems.

[0007] A punching device for processing stainless steel strips, comprising a base and two guide frames, wherein a punching frame is fixedly mounted on the top of the base, and further comprising:

[0008] Two punching modules, each of which is slidably mounted on the inner wall of the punching frame, each of which includes a drive box, a punching rod, a first sleeve, a second sleeve, and an air outlet, each of which is fixed to the bottom end of the drive box, and each of which is connected to the punching rod;

[0009] A telescopic air duct is fixedly installed at the bottom end of each sleeve 1, a sliding valve is fixedly installed inside each telescopic air duct, and both ends of each telescopic air duct are in a sleeve-type structure.

[0010] Preferably, an integrated board is fixedly installed inside the stamping frame, and an interface is fixedly installed on the top of the integrated board;

[0011] A connecting pipe is fixedly installed on the outer side of each of the first sleeves, each of the connecting pipes is connected to the integrated board, and both ends of each of the connecting pipes are in a retractable structure;

[0012] Two camera modules are rotatably mounted on the bottom end of the integrated board, and both ends of the camera modules are connected to the integrated board through a hollow rotating shaft.

[0013] Preferably, a frame is fixedly installed at the bottom end of the integrated board, a driving rod 1 is rotatably installed inside the frame, and the top end of the driving rod 1 is connected to the motor;

[0014] A sliding plate is rotatably mounted on the surface of the driving rod 1, and the side end of the sliding plate is slidably docked with the frame, and both side ends of the sliding plate are rotatably mounted with a pull rod connected to the camera module;

[0015] Two driving rods 2 are rotatably mounted inside the punching frame, and each of the driving rods 2 is threadedly passed through the side end of the driving box.

[0016] Preferably, a linkage rod is fixedly mounted on the side end portion of each driving box, and the linkage rod passes through the interior of the stamping frame;

[0017] Two punching pads are slidably mounted on the top of the base, and each punching pad is aligned with the punching rod;

[0018] Two guide rollers are arranged inside each guide frame, and a threaded rod is arranged inside each guide frame.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the present invention, when punching, the external pump guides the high-pressure air into the sleeve one, the telescopic air duct and the sleeve two through the integrated board and the connecting pipe, and splashes from the air outlet, which can not only clean the surface of the punching rod and prevent debris from adhering to and affecting subsequent punching, but also clean the debris generated by punching on the stainless steel belt, thereby ensuring a clean processing environment and improving product quality; and when the punching rod moves up and down, the sliding valve can automatically control the on and off of the high-pressure air.

[0021] In the present invention, the motor drives the driving rod to rotate, which drives the sliding plate to rise and fall and slide. The pull rod is used to make the two camera modules deflect synchronously. The angle of the camera module can be flexibly adjusted to meet the monitoring needs of different punching positions and angles. The camera module can monitor the punching position in real time and can promptly detect problems such as punching position deviation, which is convenient for the operator to make timely adjustments to ensure the quality of punching.

[0022] In the present invention, the motor drives the second driving rod to rotate, and the characteristic that the lead angle of the driving rod and the driving box thread is smaller than the friction angle is utilized to push the driving box to slide in the punching frame, thereby adjusting the distance between the two driving boxes. The punching position can be accurately adjusted according to stainless steel belts of different sizes, thereby improving the versatility and applicability of the device.

[0023] In the present invention, by cooperating with the threads of the driving rod 1 and the sliding plate, the characteristic of the thread rise angle being smaller than the friction angle and being able to self-lock is utilized to achieve precise lifting and sliding of the sliding plate, and then the angle of the camera module is accurately adjusted by the pull rod with high adjustment accuracy. The frame provides a stable installation foundation for the driving rod 1, the sliding plate and other components, ensuring the stability of the entire angle adjustment mechanism.

DETAILED DESCRIPTION

[0032] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0033] See also Figure 1 - Figure 7The present invention provides a punching device for processing stainless steel strips, comprising a base 11 and two guide frames 12. A punching frame 13 is fixedly mounted on the top of the base 11. The stainless steel strip passes through the guide frames 12. The two guide frames 12 guide and transmit the stainless steel strip. At the same time, the stainless steel strip is laid flat on the top of the base 11 under the guidance of the two guide frames 12.

[0034] Two punching modules, each punching module is slidably mounted on the inner wall of the punching frame 13, each punching module includes a drive box 14, a punching rod 15, a sleeve 16, a sleeve 21 and an air outlet 22, each sleeve 16 is fixed to the bottom end of the drive box 14, and each sleeve 21 is connected to the punching rod 15. By starting the drive box 14, the drive box 14 generates a thrust on the punching rod 15, and the drive box 14 drives the punching rod 15 to impact downward rapidly. The end of the punching rod 15 slides inside the drive box 14. The end of the punching rod 15 is a tapered structure, which quickly punches holes on the surface of the stainless steel strip;

[0035] At the same time, the telescopic air duct 18 connects the sleeve 16 and the second sleeve 21 in series. The telescopic air duct 18 is hollow in design, and high-pressure air is introduced into the interior of the connecting pipe 17 of the telescopic air duct 18, enters the interior of the sleeve 16, and then is transported to the interior of the second sleeve 21 through the telescopic air duct 18. A plurality of equidistant air outlets 22 are provided at the bottom end of the second sleeve 21. The air outlets 22 spray high-pressure air downward, and the airflow cleans the surface of the punching rod 15. At the same time, the high-pressure airflow blows onto the surface of the stainless steel belt to clean the debris generated by the punching.

[0036] A telescopic air duct 18 is fixedly installed at the bottom end of each sleeve 16, and a slide valve 19 is fixedly installed inside each telescopic air duct 18. The two ends of each telescopic air duct 18 are sleeve-type structures. The punching rod 15 moves at the end of the drive box 14. When the punching rod 15 moves upward, the punching rod 15 drives the sleeve 21 to move upward. At the same time, the sleeve 21 squeezes the end of the telescopic air duct 18 upward. The telescopic air duct 18 is gradually compressed, and the interior of the telescopic air duct 18 is closed through the slide valve 19, and the output of high-pressure air is suspended. When the punching rod 15 impacts the surface of the stainless steel belt downward, the punching rod 15 drives the sleeve 21 to move downward, and the telescopic air duct 18 is stretched and retracted. At this time, the slide valve 19 slides inside the telescopic air duct 18, opens the interior of the telescopic air duct 18, and air splashes downward through the air outlet 22;

[0037] An integrated board 23 is fixedly mounted inside the punching frame 13. An interface 33 is fixedly mounted on the top of the integrated board 23. The end of the interface 33 is connected to an external pump to introduce high-pressure air into the integrated board 23 and transport it to the inside of the sleeve 16 through the connecting pipe 17.

[0038] A connecting tube 17 is fixedly mounted on the outside of each sleeve 16. Each connecting tube 17 is connected to the integrated board 23. Both ends of each connecting tube 17 are retractable. When the two drive boxes 14 slide inside the punching frame 13, the drive boxes 14 drive the sleeve 16 to move. The connecting tube 17 retracts and contracts between the integrated board 23 and the sleeve 16, ensuring the movement of the drive boxes 14 while allowing air to be transported inside the connecting tube 17.

[0039] Two camera modules 24 are rotatably mounted on the bottom of the integrated board 23. The two ends of the camera modules 24 are connected to the integrated board 23 via hollow shafts. The ends of the camera modules 24 are equipped with lenses and a control panel. The positions of the holes are monitored through the lenses at the ends of the camera modules 24.

[0040] A frame 25 is fixedly mounted on the bottom end of the integrated board 23. A driving rod 26 is rotatably mounted inside the frame 25. The top end of the driving rod 26 is connected to a motor. The motor drives the driving rod 26 to rotate, and the driving rod 26 can rotate at a constant speed inside the frame 25.

[0041] The surface of the driving rod 26 is rotatably mounted with a sliding plate 27, and the side ends of the sliding plate 27 are slidably docked with the frame 25. The two side ends of the sliding plate 27 are rotatably mounted with pull rods 28 connected to the camera module 24. The surface of the rotating driving rod 26 is sleeved with the sliding plate 27. The thread of the driving rod 26 passes through the interior of the sliding plate 27. The thread rise angle of the driving rod 26 and the sliding plate 27 is less than the friction angle. The rotating driving rod 26 pushes the sliding plate 27 to slide up and down along the interior of the frame 25. The pull rod 28 generates a pulling force on the camera module 24, so that the two camera modules 24 are synchronously deflected at the end of the integrated board 23 to adjust the angle of the camera module 24. At the same time, the driving rod 26 stops rotating, the driving rod 26 and the sliding plate 27 can be locked by themselves, and the moving sliding plate 27 drives the pull rod 28 to swing;

[0042] Two driving rods 29 are rotatably installed inside the punching frame 13. Each driving rod 29 is threaded through the side end of the driving box 14. The thread lead angle of the driving rod 29 and the driving box 14 is less than the friction angle. The driving rod 29 is driven to rotate by the motor. The driving rod 29 generates a thrust on the driving box 14. The driving box 14 slides along the inside of the punching frame 13. The distance between the two driving boxes 14 is adjusted. The punching position can be adjusted according to stainless steel strips of different sizes. At the same time, the rotating driving rod 29 can be automatically locked with the side end of the driving box 14 to increase stability.

[0043] A linkage rod 31 is fixedly mounted on the side end of each driving box 14. The linkage rod 31 passes through the interior of the punching frame 13. When the driving box 14 moves, a thrust is generated on the linkage rod 31. The linkage rod 31 is a U-shaped structure. The moving linkage rod 31 generates a pulling force on the punching pad 32, allowing the punching pad 32 to move synchronously with the punching rod 15.

[0044] Two punching pads 32 are slidably mounted on the top of the base 11 , and each punching pad 32 is aligned with the punching rod 15 ;

[0045] Two guide rollers are provided inside each guide frame 12. A threaded rod is provided inside each guide frame 12. A sleeve is provided at the end of the guide roller. The top end of the threaded rod is inserted into the sleeve. The threaded rod is rotated to support and adjust the guide roller.

[0046] Working principle:

[0047] In the first step, the stainless steel strip is passed through the guide frame 12. The guide roller in the guide frame 12 adjusts the support position through the threaded rod, which guides and transmits the stainless steel strip so that it is laid flat on the top of the base 11 under the guidance of the two guide frames 12. The drive rod 29 is driven to rotate by the motor. Since the thread lead angle of the drive rod 29 and the drive box 14 is smaller than the friction angle, the drive rod 29 pushes the drive box 14 to slide inside the punching frame 13, and the distance between the two drive boxes 14 is adjusted to adapt to the punching position requirements of stainless steel strips of different sizes. At the same time, the drive rod 29 and the drive box 14 can be locked by themselves.

[0048] In the second step, the drive box 14 is started. The drive box 14 generates a thrust on the punching rod 15, driving the punching rod 15 to quickly impact downward. The end of the punching rod 15 slides inside the drive box 14, and its tapered end quickly punches holes on the surface of the stainless steel belt. The external pump introduces high-pressure air into the integrated board 23 through the interface 33, and then transports it to the sleeve 16 through the connecting pipe 17. When the punching rod 15 impacts downward, it drives the sleeve 21 to move downward, the telescopic air duct 18 stretches, the slide valve 19 opens, and the high-pressure air enters the sleeve 21 through the telescopic air duct 18, splashing downward from the air outlet 22, cleaning the surface of the punching rod 15 and cleaning the debris generated by punching the stainless steel belt; when the punching rod 15 moves upward, it drives the sleeve 2 21 to squeeze the telescopic air duct 18 upward, compressing it, and the slide valve 19 closes, suspending the output of high-pressure air.

[0049] When the drive box 14 moves, the linkage rod 31 is pushed, and a pulling force is generated on the punching pad 32, so that the punching pad 32 moves synchronously with the punching rod 15, ensuring that the punching pad 32 is aligned with the punching rod 15 during punching. The end lens of the camera module 24 monitors the punching position, and the motor drives the drive rod 126 in the frame 25 to rotate. The thread of the drive rod 126 passes through the sliding plate 27. Because the thread lead angle of the drive rod 126 and the sliding plate 27 is smaller than the friction angle, the rotating drive rod 126 pushes the sliding plate 27 to slide up and down along the frame 25. The pull rod 28 is driven by the sliding plate 27 to generate a pulling force on the camera module 24, so that the two camera modules 24 are synchronously deflected at the end of the integrated board 23 to adjust their angles, and when the drive rod 126 stops rotating, it locks itself with the sliding plate 27.
