Description

Technical Field

[0001] This utility model belongs to the field of hot coil spring processing technology, and in particular relates to a hot coil spring shaping and processing equipment. Background Technology

[0002] In the spring manufacturing process, after hot-rolled springs are formed, their ends typically require grinding and shaping to meet the requirements of subsequent assembly and use. Traditional spring end grinding and shaping is mostly done manually, which is not only labor-intensive but also makes it difficult to guarantee processing accuracy, resulting in low production efficiency. Although some existing automated grinding equipment can improve processing efficiency to some extent, these devices are generally designed for single-station operation. When changing spring parts, the equipment is idle, resulting in a significant waste of time and preventing further improvement in overall processing efficiency, thus failing to meet the needs of large-scale production. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a hot-rolled spring shaping and processing equipment to solve the problem of low overall processing efficiency.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A hot-rolled spring forming and processing equipment includes: a base plate, vertical plates, a grinding mechanism, and an adjusting mechanism. Two vertical plates are fixedly disposed on the upper surface of the base plate and are arranged opposite to each other along the length direction of the base plate. A grinding mechanism is installed on the inner side of the upper end of each of the two vertical plates. A U-shaped plate is slidably disposed above the base plate and between the two vertical plates. A fixing block is fixedly disposed on the upper end of the U-shaped plate. Spring placement cylinders are fixedly disposed on both sides of the fixing block. A transmission mechanism for driving the U-shaped plate to move is provided on the base plate. A fixing rod is fixedly disposed inside the spring placement cylinder. An adjusting plate is slidably sleeved on the wall of the fixing rod. An adjusting mechanism for driving the adjusting plate to move is provided on the spring placement cylinder.

[0006] Furthermore, the grinding mechanism includes a rotating rod and a grinding disc. The rotating rod is rotatably mounted on the inner side of the upper end of the vertical plate. The grinding disc is fixedly sleeved on the end of the rotating rod away from the vertical plate. The first motor is fixedly mounted on the outer wall of the vertical plate, and the output end of the first motor is fixedly connected to one end of the rotating rod.

[0007] Furthermore, the transmission mechanism includes a turntable and a round pin. A fixed plate is fixedly installed on the upper surface of the base plate, and a transmission rod is rotatably installed on the fixed plate. The turntable is fixedly sleeved on the rod wall of the transmission rod. The round pin is eccentrically installed on the side of the turntable near the U-shaped plate. One end of the round pin passes through the U-shaped plate. A second motor is fixedly installed on the end face of the fixed plate opposite to the turntable. The output end of the second motor is fixedly connected to one end of the transmission rod.

[0008] Furthermore, the adjustment mechanism includes a slider and a threaded rod. The upper surface of the spring placement cylinder has a strip-shaped opening. The slider is slidably disposed inside the strip-shaped opening. Side plates are fixedly disposed on both ends of the upper surface of the spring placement cylinder along the length direction of the strip-shaped opening. The threaded rod is rotatably disposed between the two side plates. The slider and the threaded rod are threadedly connected, and the slider is fixedly connected to the adjustment plate.

[0009] Furthermore, a dust collection hood is provided on the outer side of the grinding disc, one side of which is fixedly connected to the corresponding vertical plate, and a dust collection device is fixedly installed on the upper surface of the base plate. The air inlet of the dust collection device is connected to the dust collection hood through a connecting pipe.

[0010] Furthermore, a square hole is provided on the vertical plate, and a square rod is slidably sleeved in the square hole, with one end of the square rod fixedly connected to the U-shaped plate.

[0011] Furthermore, an anti-detachment ring is provided at the end of the circular pin that is away from the turntable.

[0012] Furthermore, a knob is fixedly sleeved at one end of the threaded rod.

[0013] Through the above technical solution, the combination of dual-station collaboration and adjustment mechanism significantly improves production efficiency and processing accuracy. Specifically, the base plate and the oppositely arranged vertical plates form a rigid support frame, ensuring that the two grinding mechanisms maintain stable alignment in space. The U-shaped plate slides between the two vertical plates through the transmission mechanism, driving the spring placement cylinders on both sides to alternately enter the processing station. That is, while one station is grinding, the other station can load and unload materials simultaneously, improving the utilization rate of the equipment's continuous operating time and significantly increasing the overall processing efficiency. At the same time, the fixed rod provides axial installation positioning for the springs, while the adjustment plate driven by the adjustment mechanism can slide along the fixed rod, which can not only adapt to the clamping requirements of springs of different lengths, but also ensure the precise alignment of the spring ends with the grinding mechanism through fine adjustment.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] In the specific embodiments provided in this disclosure, a hot-rolled spring forming and processing equipment is provided, with reference to... Figures 1 to 4 As shown, the hot-rolled spring shaping and processing equipment includes: a base plate 1, vertical plates 2, a grinding mechanism, and an adjustment mechanism. Two vertical plates 2 are fixedly mounted on the upper surface of the base plate 1 and are arranged opposite each other along the length of the base plate 1. Grinding mechanisms are installed on the inner sides of the upper ends of both vertical plates 2. A U-shaped plate 9 is slidably mounted above the base plate 1 and between the two vertical plates 2. A fixing block 11 is fixedly mounted on the upper end of the U-shaped plate 9. Spring placement cylinders 12 are fixedly mounted on both sides of the fixing block 11. A transmission mechanism for driving the U-shaped plate 9 is provided on the base plate 1. A fixing rod is fixedly mounted inside the spring placement cylinder 12. This fixing rod is used to mount the spring to be ground. Simultaneously, an adjustment plate 18 is slidably mounted on the wall of the fixing rod. An adjustment mechanism for moving the adjustment plate 18 is provided on the spring placement cylinder 12. Personnel can adjust the position of the adjustment plate 18 according to the length of the spring using the adjustment mechanism.

[0026] This hot-rolled spring shaping and processing equipment adopts a symmetrical layout. Two vertical plates 2 are fixed to the base plate 1 to form a stable frame, ensuring that the processing reference surfaces of the grinding mechanisms on both sides remain parallel. At the same time, the U-shaped plate 9 slides between the two vertical plates 2 through a transmission mechanism, driving the fixed block 11 and the spring placement cylinders 12 on both sides to alternately enter the processing position. When one station is grinding the spring end, the other station can simultaneously complete the unloading and loading operations, completely eliminating equipment idle time and improving grinding efficiency.

[0027] In some embodiments, the fixed rod inside the spring placement cylinder 12 serves as the axial positioning reference for the spring. The diameter of the fixed rod can be precisely matched with the inner diameter of the spring to ensure that there is no radial wobble after the spring is fitted. Furthermore, the wall of the fixed rod is slidably fitted with an adjusting plate 18. The spring placement cylinder 12 is provided with an adjusting mechanism that drives the adjusting plate 18 to move. The operator can precisely adjust the position of the adjusting plate 18 according to the specific length of the spring through the adjusting mechanism, so that the spring to be ground can be firmly clamped between the fixed rod and the adjusting plate 18, ensuring that the end of the spring and the grinding mechanism always maintain the optimal processing distance, thereby adapting to the processing requirements of springs of different specifications.

[0028] For example, an elastic pad is provided on the end face of the adjusting plate 18, which can prevent damage to the spring surface.

[0029] For example, the adjustment mechanism may be a pneumatic push rod, the extension rod of which drives the adjustment plate 18 to move.

[0030] In some implementations, reference Figures 1 to 4 As shown, the grinding mechanism includes a rotating rod 3 and a grinding disc 4. The rotating rod 3 is rotatably mounted on the inner side of the upper end of the vertical plate 2. The grinding disc 4 is fixedly sleeved on the end of the rotating rod 3 away from the vertical plate 2. A first motor 5 is fixedly mounted on the outer wall of the vertical plate 2. The output end of the first motor 5 is fixedly connected to one end of the rotating rod 3. The rotational motion of the rotating rod 3 is effectively transmitted to the end of the spring through the grinding disc 4, so that the grinding process can accurately cover every angle of the spring end face, ensuring uniform grinding of the entire end and avoiding uneven local wear. Furthermore, the grinding disc 4 is made of diamond or hard alloy, which can maintain good wear resistance under high load and ensure stable operation of the equipment for a long time.

[0031] For example, by precisely controlling the rotation speed and direction of the first motor 5, the rotational speed of the grinding disc 4 can be flexibly adjusted according to different spring materials and sizes, thus optimizing the adaptability of the processing technology.

[0032] In some implementations, reference Figures 1 to 4As shown, the transmission mechanism includes a turntable 13 and a pin 15. A fixing plate 17 is fixedly installed on the upper surface of the base plate 1. The fixing plate 17 is used to provide a mounting support base for the transmission mechanism. A transmission rod 14 is rotatably installed on the fixing plate 17. The turntable 13 is fixedly sleeved on the rod wall of the transmission rod 14. The pin 15 is eccentrically installed on the side of the turntable 13 near the U-shaped plate 9. One end of the pin 15 passes through the U-shaped plate 9. A second motor 16 is fixedly installed on the end face of the fixing plate 17 away from the turntable 13. The output end of the second motor 16 is fixedly connected to one end of the transmission rod 14. When the second motor 16 is started, it drives the transmission rod 14 to rotate, which in turn drives the turntable 13 to rotate, causing the eccentric pin 15 to form a periodic trajectory motion, thereby converting the rotational motion into linear reciprocating motion, driving the U-shaped plate 9 to move back and forth.

[0033] In this design, by eccentrically setting a round pin 15 on the turntable 13 and inserting a U-shaped plate 9 through one end of the round pin 15, the rotational motion can be smoothly and continuously converted into the reciprocating linear motion of the spring placement cylinder 12.

[0034] In some implementations, reference Figures 1 to 4 As shown, the end of the round pin 15 facing away from the turntable 13 is provided with an anti-detachment ring. The anti-detachment ring can prevent the round pin 15 from detaching from the U-shaped plate 9. Furthermore, when the round pin 15 passes through the U-shaped plate 9, the anti-detachment ring maintains an axial gap of 0.1-0.3mm with the outer surface of the U-shaped plate 9. This gap can ensure that the round pin 15 can rotate freely.

[0035] In some implementations, reference Figures 1 to 4 As shown, a square hole is provided on the vertical plate 2, and a square rod 10 is slidably sleeved in the square hole. One end of the square rod 10 is fixedly connected to the U-shaped plate 9. The square hole provided on the vertical plate 2 is a regular quadrilateral through hole, and its inner wall is precision machined to form a high-precision guide track. The square rod 10 is slidably sleeved in the square hole, and its cross-sectional dimensions maintain a fitting gap of 0.02-0.05mm with the square hole. The cooperative cooperation between the square hole and the square rod 10 can effectively suppress the deflection tendency of the U-shaped plate 9 during the movement.

[0036] In some implementations, reference Figures 1 to 4 As shown, the adjustment mechanism includes a slider 19 and a threaded rod 20. The upper surface of the spring placement cylinder 12 has a strip-shaped opening. The slider 19 is slidably disposed inside the strip-shaped opening. Side plates 21 are fixedly disposed on both ends of the upper surface of the spring placement cylinder 12 along the length direction of the strip-shaped opening. The threaded rod 20 is rotatably disposed between the two side plates 21. The slider 19 and the threaded rod 20 are threadedly connected, and the slider 19 is fixedly connected to the adjustment plate 18.

[0037] In some implementations, reference Figures 1 to 4As shown, a knob is fixedly sleeved at one end of the threaded rod 20. The operator can easily rotate the threaded rod 20 through the knob, thereby achieving quick and precise adjustment of the adjusting plate 18.

[0038] For example, since the slider 19 is rigidly connected to the adjusting plate 18 and its range of movement is limited by the guide of the strip, the rotation of the threaded rod 20 can drive the adjusting plate 18 to achieve high-precision linear movement within the limited path, thereby accurately adjusting the position of the adjusting plate 18 according to the specific length of the spring, so as to better polish the spring.

[0039] In some implementations, reference Figures 1 to 4 As shown, a dust collection hood 6 is provided on the outer side of the grinding disc 4. One side of the dust collection hood 6 is fixedly connected to the corresponding vertical plate 2. A dust collection device 7 is fixedly installed on the upper surface of the base plate 1. The air inlet of the dust collection device 7 is connected to the dust collection hood 6 through a connecting pipe 8. The dust collection hood 6 on the outer side of the grinding disc 4, combined with the dust collection device 7, achieves effective dust control. The dust collection hood 6 plays the role of collecting the dust generated during the grinding process, ensuring that the dust will not fall randomly during the grinding process, but can be directly concentrated in the dust collection device 7 for treatment, avoiding environmental pollution and secondary pollution of dust on the spring surface.

[0040] When using it, first rotate the threaded rod 20 on the spring placement cylinder 12 according to the length of the hot coil spring to be processed, and drive the slider 19 to slide along the length direction of the strip opening, thereby pushing the adjusting plate 18 to move along the fixed rod, and adjusting the position of the adjusting plate 18 in the spring placement cylinder 12 until it matches the length of the spring to be polished.

[0041] Next, place the two springs to be polished into the spring placement cylinders 12 on both sides respectively, with one end of the spring abutting against the adjusting plate 18. Start the first motor 5 and the second motor 16. The first motor 5 drives the rotating rod 3 and the polishing disc 4 to rotate, and the second motor 16 drives the transmission rod 14 and the turntable 13 to rotate. The eccentrically set round pin 15 slides in the U-shaped plate 9, pushing the U-shaped plate 9 to move along the length direction of the square rod 10.

[0042] When one side of the spring placement cylinder 12 moves to below the grinding disc 4, the end of the spring contacts the grinding disc 4 to perform end face grinding and shaping. At the same time, the spring to be processed can be replaced in the idle spring placement cylinder 12 on the other side, realizing the dual-station alternating operation of grinding on one side and changing materials on the other side.

[0043] The waste generated during the grinding process is collected by the dust hood 6 and sucked into the dust collection device 7 through the connecting pipe 8 to prevent the waste from scattering and polluting the environment. After the grinding is completed, the second motor 16 continues to drive the U-shaped plate 9 to move, so that the ground spring leaves the grinding disc 4 with the spring placement cylinder 12. The spring that has been loaded on the other side moves to the processing position. The above process is repeated to continuously and efficiently complete the spring shaping process.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
