Description

Technical Field

[0001] This invention relates to the field of snap ring processing technology, specifically a high-precision snap ring continuous forming processing equipment. Background Technology

[0002] Snap rings, also known as retaining rings or retaining rings, are a type of fastener widely used in machinery, electronic equipment, and automotive parts. They are installed in the grooves or holes of shafts or holes in machines or equipment to prevent axial movement of parts on the shaft or in the hole. Snap rings are usually formed by stamping with a stamping die, and their machining accuracy directly affects the assembly quality and performance of the product.

[0003] In existing snap ring manufacturing processes, snap ring forming often requires multiple sets of molds to complete different processes, and the material needs to be transferred between different machines. This not only occupies a large amount of equipment and space but also leads to long production cycles and low efficiency. Furthermore, during continuous stamping, the material is prone to deviation or misalignment during transport between stations, resulting in inaccurate stamping positions and affecting the forming accuracy of the snap ring. Additionally, dust, debris, and other impurities easily adhere to the surface of the material during transport and stamping; if not removed, this will affect stamping quality and mold life. Finally, when using traditional stamping equipment for snap ring stamping, the workpiece is prone to getting stuck in the mold slot after stamping, requiring manual removal or the use of an additional ejector device, which is inconvenient.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figure 2 , Figure 4 , Figure 5 As shown, the high-precision continuous forming processing equipment for snap rings of the present invention includes a conveyor table 1, a stamping structure 2 in the middle of the conveyor table 1, a guide structure 5 on one side of the stamping structure 2, a feeding structure 3 at the end of the conveyor table 1, and a cleaning structure 4 connected to the feeding structure 3.

[0023] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, the stamping structure 2 includes a mounting frame 201. The mounting frame 201 is fixedly connected to the top side of the conveyor table 1. A stamping plate 203 is slidably connected between the mounting frame 201 and the conveyor table 1. A template 202 is fixedly connected to the conveyor table 1 corresponding to the stamping plate 203. A mold groove 204 is opened in the middle of the template 202. A bearing block 205 is slidably connected to the inner side of the template 202 through the mold groove 204. A first spring 206 is fixedly connected between the side of the bearing block 205 and the template 202. Multiple templates 202 are arranged in a straight line on the conveyor table 1. Multiple stamping plates 203 are slidably connected between the mounting frame 201 and the conveyor table 1. The stamping plates 203 are arranged one-to-one with the mold grooves 204 opened on the bottom template 202.

[0024] Multiple hydraulic cylinders are installed on the top side of the mounting bracket 201 to independently drive the stamping plate 203. Driven by the hydraulic cylinders, the stamping plate 203 moves downwards and cooperates with the template 202 to stamp the strip material located between them. The inner cavity shape of the mold groove 204 matches the required shape of the retaining spring. Under the impact of the stamping plate 203, the strip material is stamped and formed within the mold groove 204. After stamping, the stamping plate 203 rises and resets. The bearing block 205 slides upwards along the mold groove 204 under the elastic force of the first spring 206, automatically ejecting the formed retaining spring from the mold groove 204, achieving automatic demolding and avoiding the problem of the workpiece being stuck in the mold groove and requiring manual removal. Multiple templates 202 are sequentially arranged on the conveyor table 1 to achieve continuous stamping of the retaining spring. The strip material passes through each station sequentially on the conveyor table 1, gradually completing multiple stamping processes.

[0025] Specifically, such as Figure 4 As shown, the guide structure 5 includes a lifting frame 502. Multiple lifting frames 502 are slidably connected on the conveyor table 1. The multiple lifting frames 502 are sequentially arranged between two adjacent templates 202. The lifting frame 502 has a "U" shaped structure. The two ends of the lifting frame 502 are respectively fixedly connected to the conveyor table 1 with a second spring 503. The middle part of the lifting frame 502 is rotatably connected to a squeezing roller 501. The side of the squeezing roller 501 abuts against the surface of the conveyor table 1.

[0026] As the strip passes over the surface of the conveyor table 1, the extrusion roller 501 presses against the upper surface of the strip under the elastic force of the second spring 503, applying downward pressure. Since the bearing block 205 pushes the stamped and sheared parts back to the stamping position of the strip, as the strip moves, both the strip and the stamped and sheared parts are tightly adhered to the surface of the conveyor table 1 under the action of the extrusion roller 501. During the forward conveying of the strip, the extrusion roller 501 rotates with the movement of the strip, serving as a guide without obstructing normal conveying. The lifting frame 502 automatically floats up and down under the action of the second spring 503 according to the change in strip thickness, ensuring that the extrusion roller 501 always maintains good contact with the strip. Multiple guide structures 5 are sequentially arranged between each station to ensure that the strip remains straight and accurately positioned during conveying between adjacent stations, preventing stamping position deviations caused by strip offset.

[0027] Specifically, such as Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the end of the conveyor table 1 is provided with a feeding structure 3, which includes a limiting groove 302. A limiting groove 302 is provided on each side of the end of the conveyor table 1. A sliding block 305 is slidably connected to each of the two limiting grooves 302 on both sides of the conveyor table 1. The two sliding blocks 305 are symmetrically arranged. A drive wheel 303 is provided on the top side of each sliding block 305. An auxiliary wheel 304 is provided on each side of the drive wheel 303. The auxiliary wheels 304 are rotatably connected to the sliding blocks 305. The sides of both auxiliary wheels 304 and the drive wheel 303 are tangent to the edge of the sliding block 305. Both the drive wheel 303 and the auxiliary wheels 304 are made of elastic rubber. An adjusting screw 301 is rotatably connected to the middle of the conveyor table 1. The threads at both ends of the adjusting screw 301 are in opposite directions. A threaded hole 309 is provided on the bottom side of the sliding block 305. The two sliding blocks 305 are respectively threaded to the two ends of the adjusting screw 301 through the threaded holes 309. A drive shaft 306 is provided parallel to the side of the adjusting screw 301. The end of the drive shaft 306 is rotatably connected to the conveyor table 1. The middle part of the drive shaft 306 has a hexagonal structure. A first bevel gear 307 is rotatably connected to the top side of the sliding block 305. The drive wheel 303 is rotatably connected to the first bevel gear 307. A second bevel gear 308 meshes with the side of the first bevel gear 307. The second bevel gear 308 is rotatably connected to the side of the sliding block 305. The drive shaft 306 passes through the middle of the second bevel gear 308 and slides with it.

[0028] The conveyor belt is fed in from the end of the conveyor table 1 and positioned between two sliding blocks 305. When the adjusting screw 301 is rotated, because the threads at both ends of the adjusting screw 301 are in opposite directions, the two sliding blocks 305 move synchronously in opposite directions under the constraint of the limiting groove 302, thereby adjusting the distance between the two sliding blocks 305 to accommodate conveyor belts of different widths. The drive shaft 306 is driven to rotate by a motor mounted on the side of the conveyor table 1. The hexagonal structure in the middle of the drive shaft 306 passes through the middle of the second bevel gear 308 and slides with it, so that the second bevel gear 308 can rotate synchronously with the drive shaft 306 and slide freely along the axial direction of the drive shaft 306 when the sliding blocks 305 move. The rotation of the second bevel gear 308 drives the drive wheel 303 to rotate through the first bevel gear 307. The drive wheel 303 and the auxiliary wheels 304 on both sides together clamp the edge of the conveyor belt. When the drive wheel 303 rotates, it drives the conveyor belt forward through friction. The auxiliary wheels 304 rotate with it to provide support and guidance. The drive wheel 303 and auxiliary wheel 304, made of elastic rubber, provide sufficient friction to ensure stable feeding while avoiding scratches on the surface of the material.

[0029] Specifically, such as Figure 1 , Figure 5 , Figure 8As shown, the feeding structure 3 is connected to a cleaning structure 4. The cleaning structure 4 includes a side shaft 404. A side shaft 404 is fixedly connected to each side of the conveyor table 1. A connecting plate 403 is rotatably connected to each side of the conveyor table 1 via the side shaft 404. A swing shaft 402 is rotatably connected between the ends of the two connecting plates 403. A cleaning roller 401, which is a felt structure, is fixedly connected to the middle of the swing shaft 402. A torsion spring 410 is fixedly connected between the connecting plate 403 and the side of the conveyor table 1. A first gear 405 is fixedly connected to one end of the swing shaft 402. A second gear 406 is rotatably connected to the side shaft 404 on the same side as the first gear 405. The first gear 405 and the second gear 406 mesh with each other. One end of the drive shaft 306 is fixedly connected to a second pulley 409, and the end of the side shaft 404 is fixedly connected to a first pulley 407. A transmission belt 408 is sleeved between the first pulley 407 and the second pulley 409. The first pulley 407 and the second gear 406 are both located on the same side shaft 404.

[0030] When the drive shaft 306 rotates, it drives the second pulley 409 to rotate synchronously. The second pulley 409 drives the first pulley 407 to rotate via the transmission belt 408. The first pulley 407 and the second gear 406 are both fixed on the same side shaft 404, so the second gear 406 rotates synchronously with the first pulley 407. The second gear 406 meshes with the first gear 405, driving the first gear 405 and the swing shaft 402 to rotate. The swing shaft 402 drives the cleaning roller 401 to rotate. The cleaning roller 401 has a felt structure and continuously cleans dust, debris, and other impurities adhering to the surface of the conveyor belt during rotation. Under the elastic force of the torsion spring 410, the connecting plate 403 keeps the cleaning roller 401 pressed firmly against the surface of the conveyor belt, ensuring the cleaning effect. The driving force of the cleaning structure 4 comes from the drive shaft 306 of the feeding structure 3, realizing the linkage between the cleaning action and the feeding action. No additional power source is required, resulting in a compact, energy-efficient, and high-performance structure.

[0031] In use, this invention first rotates the adjusting screw 301 according to the width of the strip to be processed, causing the two sliding blocks 305 to move synchronously to a suitable distance, so that the edge of the strip is exactly between the drive wheel 303 and the auxiliary wheel 304. The strip is fed from the end of the conveyor table 1, and the motor is started to drive the drive shaft 306 to rotate. The drive wheel 303 continuously conveys the strip forward under the action of friction. The strip passes through the cleaning roller 401 of the cleaning structure 4 in sequence, and surface impurities are cleaned. Then it enters each stamping station in sequence, and each stamping plate 203 is pressed down synchronously under the drive of the hydraulic cylinder, completing each stamping process in the corresponding mold groove 204. After each stamping process is completed, the bearing block 205 automatically ejects the formed part under the action of the first spring 206, realizing automatic demolding. As the strip moves between the templates 202, it enters the guide structure 5. The extrusion roller 501 presses the strip onto the surface of the conveyor table 1 to ensure that the strip is straight and in an accurate position. The strip is continuously conveyed between each station by the feeding structure 3 to achieve continuous automated processing.
