[0016] In summary, compared with the prior art, the punching device for chain processing and production provided by the present invention has the following beneficial effects: 1. In the present invention, the lubricating oil is pressed into the oil filling box through the conduit, then sprayed out through the oil filling hole, and then flows down after being blocked by the baffle. The baffle prevents the lubricating oil from spraying on all sides, reducing the use rate of the lubricating oil. Finally, it flows evenly on the surface of the punch head through the oil overflow port. The lubricating oil can significantly reduce the friction resistance during the punching process, protect the machinery and the processed parts, thereby reducing wear and extending the life of the equipment. At the same time, the lubricating oil has good cooling properties, can effectively discharge the heat generated during the punching process, maintain temperature stability, and ensure the accuracy of the processing size; 2. In the present invention, when the punching head is punching, the punching head contacts the steel strip, so that the punching head first moves upward for a distance, and then limits the position for punching. At this time, the punching head drives the support plate to move upward, drives the push rod to move upward, and thus drives the piston to squeeze the lubricating oil in the oil storage tank. At this time, the second solenoid valve is closed, and the first solenoid valve is opened to discharge the lubricating oil into the guide tube. After the punching is completed, the punching head is reset and the piston is pulled back. At this time, the first solenoid valve is closed, and the second solenoid valve is opened to inject new lubricating oil into the oil storage tank. There is no need for continuous oil injection, which reduces the cost of use; 3. In the present invention, the second cylinder drives the fixed block to press down, thereby driving the punch head to punch holes in the steel strip. When punching holes, the use of the damping block and the spring can buffer and reduce shock on the punch head, reduce noise generation, thereby improving the comfort of the working environment, and at the same time ensuring that the punch head operates in a stable environment, improving the punching accuracy, and extending the service life of the punching equipment; 4. In the present invention, the stamping waste falls into the bottom of the cleaning box through the stamping hole and is submerged by the cleaning liquid. At this time, the vibration motor works to make the cleaning box vibrate, so that the lubricating oil on the surface of the waste can be cleaned and removed, eliminating the trouble of subsequent treatment. The vibration of the cleaning box improves the cleaning effect; 5. In the present invention, after the waste is cleaned, the third cylinder lifts up the cleaning box, and the nozzle flushes into the cleaning box to remove the oil stains adhering to the waste, further improving the cleaning effect and facilitating the subsequent recycling work.

[0018] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] Embodiment 1: refer to Figure 1 A punching device for chain processing and production includes a base 1, two groups of symmetrical brackets 2 are fixedly installed on both sides of the upper surface of the base 1, a rotating shaft 3 is rotatably installed on the top of the bracket 2, and a steel belt 4 for chain processing is rolled up on the surface of the rotating shaft 3.

[0020] refer to Figure 1 and Figure 3 A support seat 5 is fixedly installed on the upper surface of the base 1 and located between the two brackets 2. A plurality of groups of L-shaped plates 8 are symmetrically fixedly installed on the upper surface of the support seat 5 and located on both sides of the steel belt 4. A rotating column 9 is rotatably installed between the top of the L-shaped plate 8 and the support seat 5. A roller 10 is fixedly installed in the middle of the rotating column 9. The roller 10 is located on both sides of the steel belt 4, and the surface of the roller 10 is in contact with the side of the steel belt 4.

[0021] refer to Figure 1 , Figure 3 and Figure 4 A mounting plate 11 is fixedly installed on the back side of the base 1, and two symmetrical first cylinders 12 are fixedly installed on the upper surface of the mounting plate 11. The output end of the first cylinder 12 passes through the mounting plate 11 and is slidably fitted, and a fixing plate 13 is fixedly installed at the end. The fixing plate 13 is U-shaped, and a conveying roller 14 is rotatably installed inside the fixing plate 13. A conveying motor 15 for driving the conveying roller 14 is fixedly installed on one side of the fixing plate 13.

[0022] Furthermore, when in use, the first cylinder 12 drives the fixed plate 13 to move downward, so that the lower surface of the conveying roller 14 contacts the upper surface of the steel belt 4, and then controls the conveying motor 15 to work, driving the conveying roller 14 to rotate, so that the conveying roller 14 conveys the steel belt 4. When the steel belt 4 is conveyed, the rollers 10 on both sides guide it to prevent the steel belt 4 from deviating during transportation and affecting the stamping work.

[0023] Embodiment 2: refer to Figure 1 and Figure 2 A pad 6 is fixedly installed on the upper surface of the support seat 5, which is used to support the steel strip 4 during stamping to improve the stamping effect. A penetrating stamping hole 7 is opened on the upper surface of the pad 6 to discharge waste when the steel strip 4 is stamped.

[0024] refer to Figure 1 , Figure 5 and Figure 6 A second cylinder 16 is fixedly installed in the middle of the mounting plate 11, and the output end of the second cylinder 16 passes through the mounting plate 11 and is slidably fitted, and a fixed block 17 is fixedly installed at the end, and a damping block 18 is fixedly installed inside the fixed block 17. The damping block 18 is a prior art and is an elastic material mainly used to reduce noise and vibration. A punch head 19 is arranged inside the damping block 18, and the punch head 19 slides inside the fixed block 17. A support plate 20 is fixedly installed in the middle of the punch head 19, and a spring 21 penetrated by the punch head 19 is fixedly installed on the upper surface of the support plate 20 and the lower surface of the fixed block 17.

[0025] Furthermore, when in use, the second cylinder 16 drives the fixed block 17 to press down, thereby driving the punch head 19 to punch the steel strip 4. When punching, the use of the damping block 18 and the spring 21 can buffer and reduce shock to the punch head 19, reduce noise generation, thereby improving the comfort of the working environment, and at the same time ensure that the punch head 19 operates in a stable environment, improve stamping accuracy, and extend the service life of the stamping equipment.

[0026] refer to Figure 6 and Figure 7An oil storage tank 22 is fixedly installed inside the fixed block 17 and on one side of the damping block 18. The top of the oil storage tank 22 is connected to a conduit 25. The connection between the conduit 25 and the oil storage tank 22 is connected to a first solenoid valve 26. One side of the oil storage tank 22 is connected to an oil inlet pipe 27 that passes through the fixed block 17. The oil inlet pipe 27 is externally connected to an oil inlet device, which is a prior art and does not need to be drawn and described in detail here. The oil inlet pipe 27 is connected to a second solenoid valve 28. A piston 24 is slidably installed on the back of the oil storage tank 22. A push rod 23 that passes through the lower surface of the fixed block 17 is fixedly installed on the lower surface of the piston 24. The bottom end of the push rod 23 is fixed to the upper surface of the support plate 20.

[0027] Furthermore, during use, when the punch head 19 is punching, the punch head 19 contacts the steel strip 4, so that the punch head 19 first moves upward for a distance, and then limits the position for punching. At this time, the punch head 19 drives the support plate 20 to move upward, drives the push rod 23 to move upward, and thus drives the piston 24 to squeeze the lubricating oil in the oil storage tank 22. At this time, the second solenoid valve 28 is closed, and the first solenoid valve 26 is opened to discharge the lubricating oil into the conduit 25. After the punching is completed, the punch head 19 is reset and the piston 24 is pulled back. At this time, the first solenoid valve 26 is closed, and the second solenoid valve 28 is opened to inject new lubricating oil into the oil storage tank 22. There is no need for continuous oiling, which reduces the small consumption of lubricating oil and thus reduces costs.

[0028] refer to Figure 6 and Figure 7 An oil filling groove 29 is provided inside the punch head 19, and an oil filling box 30 is fixedly installed inside the oil filling groove 29. The upper surface of the oil filling box 30 is connected to the conduit 25, and a plurality of oil filling holes 31 are evenly provided on the outside of the oil filling box 30. A baffle 32 is fixedly connected to the outside of the oil filling groove 29, and an oil overflow port 33 is provided between the bottom end of the baffle 32 and the oil filling groove 29. The outer end surface of the oil overflow port 33 is rounded to facilitate the flow of the lubricating oil, which is different from the spraying oiling method. The spraying method requires additional equipment to achieve uniform spraying, and will also cause waste of lubricating oil and increase the cost of use.

[0029] Furthermore, during use, the lubricating oil is pressed into the oil filling box 30 from the conduit 25, and then sprayed out through the oil filling hole 31, and then flows down after being blocked by the baffle 32. The baffle 32 prevents the lubricating oil from spraying on all sides, thereby reducing the utilization rate of the lubricating oil, and finally flows evenly on the surface of the punch head 19 through the oil overflow port 33. The lubricating oil can significantly reduce the friction resistance during the stamping process, protect the machinery and processed parts, thereby reducing wear and extending the life of the equipment. At the same time, the lubricating oil can effectively absorb and take away the heat generated by friction, prevent mechanical parts from overheating and being damaged, and ensure the accuracy of the processed dimensions.

[0030] Embodiment three: refer to Figure 1An installation cavity 34 is provided inside the support seat 5, a first slide groove 35 is provided on the lower surface of the installation cavity 34, a collection box 36 for recycling stamping waste of the steel strip 4 is slidably installed inside the first slide groove 35, a handle 37 is fixedly installed on the front surface of the collection box 36, and the top of the collection box 36 is opened.

[0031] Furthermore, when in use, the collection box 36 is pushed into the installation cavity 34 through the first slide groove 35, so that the collection box 36 is located directly below the cushion block 6. After the work is completed, the collection box 36 can be pulled out by the handle 37, and the collected waste can be taken out for recycling, thereby reducing the cost.

[0032] refer to Figure 8 and Fig. 9 A mounting block 38 is fixedly installed inside the collection box 36, and a second slide groove 39 is opened on the opposite side of the mounting block 38. A cleaning box 40 is slidably installed inside the second slide groove 39. Slide blocks 41 are fixedly installed on both sides of the cleaning box 40, and the cleaning box 40 is slidably installed inside the second slide groove 39 through the slide blocks 41. A limit block 42 is fixedly installed on the top of the slide block 41.

[0033] refer to Fig. 9 The top of the cleaning box 40 is open, and a detachable horizontal plate 43 is installed on the top of the cleaning box 40. A vibration motor 44 is fixedly installed on the upper surface of the horizontal plate 43. A drainage hole 47 is connected to the back side of the collecting box 36, and a bottom plate 45 is fixedly installed in the inner cavity of the collecting box 36. The upper surface of the bottom plate 45 is filled with cleaning liquid, and the cleaning liquid covers half of the cleaning box 40.

[0034] Furthermore, when the steel strip 4 is stamped, the stamping waste falls into the bottom of the cleaning box 40 through the stamping hole 7 and is submerged in the cleaning liquid. At this time, the vibration motor 44 works to vibrate the cleaning box 40, thereby cleaning and removing the lubricating oil on the surface of the waste, eliminating the trouble of subsequent processing. The vibration of the cleaning box 40 improves the cleaning effect.

[0035] refer to Figure 8 A third cylinder 46 is fixedly installed in the inner cavity of the collecting box 36 and below the bottom plate 45. The output end of the third cylinder 46 passes through the bottom plate 45 and is slidably fitted and sealed with the bottom plate 45. Nozzles 48 are fixedly installed on both sides of the top of the collecting box 36. The nozzles 48 are matched with the cleaning box 40, and the nozzles 48 are external water supply equipment. The water supply equipment is a prior art and does not need to be drawn and described in detail here.

[0036] Furthermore, after the waste is cleaned, the third cylinder 46 lifts up the cleaning box 40, and the nozzle 48 flushes into the cleaning box 40 to remove the oil stains adhering to the waste, further improving the cleaning effect and facilitating the subsequent recycling work.
