With its advantages of high efficiency, high precision, and low cost, stamping technology has become a core process in the production of slide rail components.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Please see the attached Figure 1 The embodiment of the present invention provides a spare parts stamping device for slide rail manufacturing, including a frame 1, a vibrating screen 2, and a feeding guide rail 3. A connecting member 6 is installed at one end of the frame 1, and a cylinder 7 is fixedly connected to the top of the connecting member 6. A pull block 8 is fixedly connected to the output end of the cylinder 7, and a stamping assembly is fixedly connected to one end of the pull block 8. A plurality of support frames 22 are fixedly connected to the top of the frame 1. Conveyor belts 23 are installed at both ends of the support frames 22 by installing conveyor rollers for transporting workpieces. A motor 12 is installed at one end of the support frame 22, and one of the conveyor rollers is installed at the output end of the motor 12. An air cooling assembly is provided at one end of the support frame 22. A large pallet 4 and a small pallet 5 are fixedly connected to one end of the frame 1, respectively, for supporting a cargo box 33 to realize material reception. A positioning mechanism is provided at one end of the support frame 22. The vibrating screen 2 is connected to one end of the feeding guide rail 3 and is installed on the top of the frame 1 for transporting workpieces.

[0034] Specifically, the entire device is supported by a frame 1. At the material feed end, a vibrating screen 2 is mounted on one end of the top of the frame 1. The mechanism operates on the principle of an existing electromagnetically driven spiral feed tray. The spiral track within the tray adjusts and arranges the randomly stacked rail components, preferably rail gaskets or end caps, through high-frequency vibration. The outlet of the vibrating screen 2 is directly connected to the inlet of the feed rail 3.

[0035] After the material leaves the feeding guide rail 3, it enters the conveyor belt 23, and the support frame 22 provides structural support for the conveyor belt 23. It also serves as a platform for carrying the positioning mechanism and air cooling components. Multiple support frames 22 are fixed on the top of the frame 1 and arranged along the direction of material movement.

[0036] The conveyor belt 23 is mounted on conveyor rollers mounted on both ends of the support frame 22, wherein the active conveyor roller is connected to the output shaft of the motor 12. The motor 12 can be a stepper motor or a servo motor, and its step frequency and start and stop timing are controlled by existing programs, so that each component can stay at the preset stamping processing station.

[0037] The cylinder 7 and the connector 6 are fixed on one side of the frame 1, and their position is opposite to the processing station on the conveyor belt 23. The cylinder 7 is fixed vertically on the top of the connector 6. The selection of the cylinder 7 is based on the tonnage required for the stamping process. Usually, a double-acting cylinder 7 is preferred to achieve powered downward pressure and forced return. The output end of the piston rod of the cylinder 7 is connected to the pull block 8, and the pull block 8 performs vertical reciprocating motion following the extension and contraction of the cylinder 7. One side of the pull block 8 is connected to the stamping assembly, which includes a punch head 10 that performs the final forming or punching. The reciprocating motion of the cylinder 7 is directly converted into the stamping stroke of the stamping assembly through the pull block 8.

[0038] One end of the frame 1 is fixedly connected to a large tray 4 and a small tray 5. The large tray 4 is on the top, providing support and sliding guidance for the cargo box 33, and the small tray 5 is on the bottom, used to receive small debris that may leak from the sieve holes of the cargo box 33 to achieve secondary separation.

[0039] Please see the attached Figure 2 -Attached Figure 4 The positioning mechanism includes an equipment box 13, which is fixedly connected to the bottom of the support frame 22. A plurality of cross bars 16 are fixedly connected to the interior of the equipment box 13. A card plate 17 is slidably connected to the outer wall of the cross bar 16. A plurality of compression springs 19 are installed inside the card plate 17. An extension block 39 is slidably connected to one end of the card plate 17. A positioning block 18 is fixedly connected to one end of the extension block 39. When the two positioning blocks 18 are in contact, a stamping groove is formed for fixing the workpiece.

[0040] A gear rod 11 is fixedly connected to the bottom of the pull block 8. A worm 14 is rotatably connected to one end of the inner wall of the equipment box 13. One end of the worm 14 is fixedly connected to the fourth gear 9. A worm wheel 15 is rotatably connected to the inner wall of the equipment box 13. The top of the worm wheel 15 is fixedly connected to a first rotating rod 20. Both ends of the first rotating rod 20 are rotatably connected to a second rotating rod 21. The second rotating rod 21 is rotatably connected to the top of the clamping plate 17. The worm 14 and the worm wheel 15 are meshed, and the gear rod 11 is meshed with the tooth end of the fourth gear 9.

[0041] Specifically, a plurality of cross bars 16 are fixedly provided inside the equipment box 13 along its length direction, and are used as guide rails for the card plate 17 .

[0042] Two clamping plates 17 are mounted on the outer wall of the crossbar 16 through internal through-holes. The two clamping plates 17 can only move linearly toward or away from each other. Each clamping plate 17 has an internal cavity containing multiple compression springs 19. The end of the clamping plate 17 facing the workpiece is connected to an extension block 39 through a sliding fit. One end of the compression spring 19 is connected to the clamping plate 17 body, and the other end is connected to the extension block 39.

[0043] The outer end of the extension block 39 is fixedly connected to a positioning block 18. The inner surfaces of the two positioning blocks 18 can be processed into corresponding groove shapes according to the circular shape of the preferred slide rail gasket or the special shape of the end cover. When the two positioning blocks 18 are driven to contact each other, their grooves together form a stamping groove that fits tightly with the shape of the workpiece. This elastic connection formed by the extension block 39 and the compression spring 19 allows the positioning block 18 to produce a slight concession when contacting a workpiece with a slightly deviated size, thereby achieving adaptive clamping, which not only ensures the clamping force but also avoids rigid impact on the workpiece. In addition, the conveyor belt 23 is directly below the positioning mechanism. In the fixed state, the two positioning blocks 18 are in a fitted state, and the bottom is the conveyor belt 23, so as to achieve bottom support for the bottom of the workpiece and avoid instability caused by suspension.

[0044] Specifically, when the cylinder 7 drives the pull block 8 downward, the gear rod 11 moves vertically downward. As the gear rod 11 descends, its teeth engage with those of the fourth gear 9, converting its linear motion into rotational motion, which in turn drives the worm 14 to rotate synchronously. As the worm 14 rotates, it engages with a worm wheel 15 rotatably connected to the equipment box 13. The rotation of the worm 14 drives the worm wheel 15, which in turn drives the first rotating rod 20 to rotate synchronously.

[0045] The two ends of the first rotating rod 20 are rotatably connected to the second rotating rod 21. The other end of each second rotating rod 21 is also rotatably connected to the top of the clamping plate 17 on the corresponding side through a pin shaft. The rotational motion of the first rotating rod 20 can be converted into synchronous and opposite linear motion of the two clamping plates 17, driving the positioning blocks 18 to move toward each other, thereby completing the clamping and fixation of the workpiece on the conveyor belt 23. The entire process is completely synchronized with the downward pressing action of the punch head 10, and the workpiece is locked at the moment before punching occurs, thereby reducing manual participation and improving the punching effect. While the two positioning blocks 18 clamp the workpiece, the punch head 10 continues to move downward for punching, and the compression spring 19 is compressed and further clamps the workpiece. Cooperating with the conveyor belt 23 under the positioning block 18, the clamping stability of the workpiece is improved, and the workpiece will not be displaced due to the punching pressure, thereby improving the processing accuracy. The current existing technology does not clamp the workpiece when punching, and punching will cause the workpiece to shift, affecting the processing accuracy. The present invention automatically clamps the workpiece while punching, realizes the integrated operation of clamping and punching, improves the processing accuracy, and thus improves the production efficiency.

[0046] Please see the attached Figure 1 The stamping assembly includes a stamping head 10, which is fixedly connected to one side of the pull block 8. A guide rail is provided at one end of the connecting member 6. The stamping head 10 is slidably connected to the inner wall of the guide rail for limiting the stamping head 10. The stamping head 10 is slidably connected to the inside of the stamping groove.

[0047] Specifically, in order to constrain the motion trajectory of the punch head 10 during the reciprocating process, a vertical guide rail is machined or installed at one end of the connector 6 of the fixed cylinder 7, and the base of the punch head 10 is provided with a matching slider structure, so that the punch head 10 can be tightly slidably connected to the inner wall of the guide rail. This design provides a vertical motion guide for the punch head 10, offsets the lateral force generated during the punching process, suppresses shaking or deflection, and thus limits the punch head 10 to a single direction of up and down linear motion, further improving processing accuracy.

[0048] When the cylinder 7 drives the pull block 8 downward, driving the punch 10 downward, the working end of the punch 10 precisely enters the punching groove formed by the closed two positioning blocks 18. The inner wall contour of the punching groove matches the shape of the workpiece, and the working end contour of the punch 10 forms a processing fit with the inner cavity of the punching groove. Because the workpiece has been pre-clamped and fixed in the punching groove by the positioning mechanism, the entry of the punch 10 applies pressure to a specific part of the workpiece, completing the predetermined stamping operation.

[0049] Please see the attached Figure 5 -Attached Figure 9The air-cooling assembly includes a protective cover 24, which is fixedly connected to one end of the support frame 22. A first gear 28, a second gear 29, and a third gear 30 are rotatably connected to the interior of the protective cover 24. The first gear 28, the second gear 29, and the third gear 30 are meshed with each other. One end of the third gear 30 is fixedly connected to a fan blade 31. An oscillation mechanism is provided at one end of the air-cooling assembly. An air inlet 32 ​​is installed at one end of the protective cover 24. An air duct 26 is fixedly connected to one end of the protective cover 24 for supplying air to a plurality of air supply blocks 25 mounted on the outer wall of the support frame 22. One end of the air supply block 25 has an air duct 27. The oscillation mechanism includes an eccentric disk 36, which is fixedly connected to one end of the fan blade 31 and rotatably connected to the outside of the protective cover 24. A steel cable 37 is rotatably connected to the outer wall of the eccentric disk 36, and one end of the steel cable 37 is connected to the cargo box 33. One end of the cargo box 33 is fixedly connected to multiple push rods 34, which extend through and slidably connect to one end of the large tray 4. One end of the push rods 34 is sleeved with a spring 35. The bottom of the large tray 4 is hollow and perpendicular to the top of the small tray 5. The bottom of the cargo box 33 is provided with multiple mesh holes. A rotating shaft 38 is mounted on the top of the frame 1, and a steel cable 37 is movably connected to one end of the outer wall of the rotating shaft 38.

[0050] Specifically, the air cooling assembly of the present device has its main body covered by a protective cover 24. The protective cover 24 is fixed to the support frame 22 by a flange or bolts. The first gear 28 inside the protective cover 24 is driven on the power output link of the motor 12.

[0051] The protective cover 24 is internally connected to a gear speed-increasing system, which is composed of a first gear 28, a second gear 29 and a third gear 30 that are meshed and connected in sequence. Among them, the first gear 28 is a large-diameter gear, and the third gear 30 is a small-diameter gear, with the second gear 29 serving as an intermediate transition. When the power input drives the first gear 28 to rotate, the rotation speed is amplified step by step, and eventually the third gear 30 obtains a rotation speed much higher than the input end, and drives the fan blades 31 to rotate, thereby generating a strong and continuous airflow inside the protective cover 24. An air inlet 32 ​​is provided at one end of the protective cover 24. The air inlet 32 ​​can adopt a shutter structure with an adjustable opening. By adjusting the opening and closing size, the air intake volume can be controlled, and then the intensity of the final blown airflow can be adjusted.

[0052] The other end of the protective cover 24 is connected to an air duct 26 . The pressurized air generated by the fan blades 31 is collected and directed to the air duct 26 . The air duct 26 is laid along the outer wall of the support frame 22 . The branches of the air duct 26 are connected to multiple air supply blocks 25 .

[0053] A plurality of air supply blocks 25 are installed around the stamping station, and air ducts 27 are provided inside the air supply blocks. The outlets of these air ducts 27 are preferably configured as flat nozzles, facing both sides of the conveyor belt 23. The support frame 22 forms a shield on both sides of the conveyor belt 23. When the air flows through, a high-speed, directional sheet-like air curtain is formed, which blows the metal debris generated during the stamping process into the cargo box 33 at the end of the device along the direction of material conveying. In this process, the debris can be effectively prevented from splashing everywhere and moved to one side, thereby improving the safety of operation in other directions. In order to prevent debris from splashing during use, the existing stamping device generally requires specially customized tempered glass of the right size to cover the entire device. However, this significantly increases the cost of use, and manual auxiliary cleaning is still required after covering. The long-term splashing of debris will cause the clarity of the tempered glass to decrease, so it needs to be replaced every once in a while, further increasing the cost. However, this solution reduces the use of additional devices through the cooperation of the support frame 22 and the air-cooling assembly during use, and is not assembled through existing technology, but is improved on the existing basis and extends the existing technology to achieve significant effects.

[0054] During operation of the air-cooling assembly, the fan blades 31 extend through the shaft 38 outside the protective cover 24. An eccentric disc 36 is fixedly connected to the end of the shaft. A steel cable 37 is connected to the eccentric point on the outer edge of the eccentric disc 36. The other end of the steel cable 37 passes upward around a freely rotatable shaft 38 mounted on the top of the frame 1. The shaft 38 acts as a pulley, changing the direction of the pulling force. The end of the steel cable 37 is then connected to one side of the cargo box 33. When the fan blades 31 drive the eccentric disc 36 to rotate, the steel cable 37 is periodically tightened and loosened. To prevent the steel cable 37 from breaking, multiple push rods 34 are fixedly connected to the bottom of the cargo box 33. These push rods 34 extend through guide holes set on the side walls of the large tray 4 and are covered with multiple compression springs 35.

[0055] When tightened, the steel cable 37 overcomes the elastic force of the spring 35 and pulls the cargo box 33 backward for a distance; when relaxed, the compressed spring 35 rebounds and pushes the cargo box 33 back to its original position. This process repeats itself, causing the cargo box 33 to vibrate back and forth at a high frequency on the large pallet 4.

[0056] After the mixture of finished parts and scraps falls into bin 33, the continuous vibration causes the material inside to tumble and stratify. Smaller, lighter scraps gradually sink during the vibration, passing through the sieve holes at the bottom and falling beneath large tray 4. The bottom of large tray 4 is designed as a hollow structure, with the top of small tray 5 directly below it. Therefore, the scraps that pass through the sieve holes further pass through the hollow area of ​​large tray 4 and are ultimately collected in small tray 5, while the larger finished parts remain in bin 33, achieving efficient separation of finished products and scraps.

[0057] Existing stamping devices typically follow the stamping process with a separation step, which requires manual sorting. However, the resulting debris and fragments often have sharp edges, making the operation time-consuming and labor-intensive, and also increasing the cost of sorting tools, such as steel gloves. However, during the startup of the original air-cooling component, this device can automatically sort and separate the cargo box 33 by increasing its rotational speed. The corresponding sieve holes can be adjusted according to the sorting accuracy, and are not limited to a single large tray 4 and a single small tray 5. Multiple layers of separation can be achieved through series connection. This effect is achieved without adding additional costs, improving the overall processing effect.

[0058] Working principle: When the staff uses this stamping device to manufacture the slide rail parts, they first pour the parts into the vibrating screen 2, and arrange the parts neatly on the feeding guide rail 3 through its vibration mechanism, and then continuously push them onto the conveyor belt 23 on the top of the support frame 22, and realize the pre-processing preparation process by synchronously setting the stepping frequency of the motor 12.

[0059] After completing the preparation process, the pulling frequency of the cylinder 7 is set according to the gap between the workpieces and the stepping frequency. After the setting is completed, after the workpiece enters the stamping range, the pull block 8 is pushed down to drive the extrusion punch head 10 to move downward. During the displacement process, in order to ensure the stability of the workpiece during the stamping process, when the pull block 8 moves down, it will drive the gear rod 11 to pass through the equipment box 13 and engage with the fourth gear 9 set inside it, thereby driving the worm 14 rotating inside the equipment box 13 to engage with the worm wheel 15, thereby through the connected first rotating rod 20, the card plates 17 connected to the second rotating rods 21 on both sides are pulled closer to each other by rotation, thereby prompting the positioning blocks 18 on both sides of the top of the card plate 17 to complete the fit and clamping with the workpiece, thereby improving the stability of the workpiece during the stamping process; during this operation, for workpieces of different sizes, adaptive adjustment can be achieved through the cooperation of the extension block 39 and the compression spring 19, and the workpiece is fully limited to the proximal ends of the positioning blocks 18 on both sides.

[0060] Since it is inevitable that debris will damage the workpiece, during the processing, the motor 12 drives the conveyor belt 23 to operate, and at the same time, it will simultaneously drive the first gear 28, the second gear 29 and the third gear 30 provided in the inner cavity of the protective cover 24 to engage and connect, and realize the effect of the speed-increasing fan blade 31 rotating in the inner cavity of the protective cover 24 through the gear ratio. Through such a design, during the operation of the conveyor belt 23, the blowing effect can be achieved with the help of the power of the motor 12 and the gear ratio speed increase; the corresponding air supply blocks 25 are arranged on both sides of the top of the support frame 22, and the air duct 27 is facing the direction of operation, so that the wind can blow along the direction of operation of the workpiece, helping to discharge the debris into the cargo box 33 while cooling the entire equipment.

[0061] When debris enters the cargo box 33, in order to reduce the time consumed by manual sorting, the fan blades 31 rotate in accordance with the stepping frequency cycle, and simultaneously drive the eccentric disk 36 to rotate, and then, through the cooperation of the steel cable 37 and the first gear 28, pull the cargo box 33 to slide in the opposite direction of the workpiece movement in the large tray 4. Since a push rod 34 and a spring 35 are provided at one end of the cargo box 33, when the steel cable 37 is located at the eccentric position of the eccentric disk 36, the restoring force of the spring 35 pushes the cargo box 33 back to its original position. This reciprocating motion can achieve a layered screening effect on the workpieces in the cargo box 33, and promote diversion through the setting of the sieve holes, thereby improving processing efficiency.

[0062] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
