Description

Technical Field

[0001] The invention relates to the technical field of oil supply systems, in particular to a punching oil supply system for an automobile safety belt retractor. Background Art

[0002] In the field of automobile manufacturing, the manufacture of seat belt retractors plays a pivotal role, and the quality and performance of the final product are directly related to the safety of passengers. As the core component of the seat belt retractor, the retractor guide ring must be processed by extremely precise punching and flanging process to ensure that it has sufficient structural strength and long-term stability. However, the traditional punching and flanging processing technology has exposed many drawbacks in practical applications.

[0003] Specifically, traditional punching and flanging processes mostly rely on a single oil outlet to spray lubricating oil into the processing area. Although this method can reduce friction and lower the temperature during processing through lubricating oil to a certain extent, its limitations are also obvious. First, due to the single oil outlet, the spray range of the lubricating oil is limited, resulting in uneven distribution of the lubricating oil, making it difficult to accurately cover all key friction contact points, thereby affecting the overall lubrication effect. Secondly, considering the complex structural relationship between the stamping sleeve and the retractor guide ring, it is difficult for the lubricating oil to quickly and evenly cover the connection area between the two, which not only reduces the processing efficiency, but also has a certain impact on the quality of the final product. In response to the above problems, the present invention document proposes a punching and oiling system for a car seat belt retractor. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose a car seat belt retractor punching and oiling system that can evenly and comprehensively spray lubricating oil on the places to be punched and flanging inside the retractor guide ring, ensuring that the lubricating oil can be accurately sprayed to each key friction point, effectively reducing the friction resistance during the punching process, while ensuring the cooling effect, and improving the processing efficiency and the quality of the finished product.

[0018] Compared with the prior art, the present invention provides a punching and oiling system for a car seat belt retractor, which has the following beneficial effects:

[0019] 1. The punching and oiling system of the automobile seat belt retractor is provided with an adjustment structure and an oiling assembly. When the punching sleeve and the punching block cooperate with each other to perform punching and flanging processing on the retractor guide ring, the driving assembly first contacts with the retractor guide ring. Under the extrusion of the retractor guide ring, the driving assembly moves close to the mounting plate. When the driving assembly pushes the tooth plate to move, the driven gear drives the rotating base, the first oil outlet cylinder and the second oil outlet cylinder to rotate with the cooperation of the driving gear, so that the first oil outlet groove and the second oil outlet groove can evenly and comprehensively spray lubricating oil to the places to be punched and flanging inside the retractor guide ring, ensuring that the lubricating oil can be accurately sprayed to each key friction point, effectively reducing the friction resistance in the punching process, while ensuring the cooling effect, and improving the processing efficiency and the quality of the finished product.

[0020] 2. The punching oil supply system of the automobile seat belt retractor is provided with a first oil outlet groove and a second oil outlet groove. Since the diameter of the first oil outlet cylinder is the same as the diameter of the inner wall of the stamping sleeve, when the first oil outlet cylinder is retracted into the inside of the stamping sleeve, the first oil outlet cylinder is closely fitted with the inner wall of the stamping sleeve. The oil outlet direction of the first oil outlet groove is set downward, so that after the lubricating oil is sprayed out through the first oil outlet groove, under the cooperation of the spray force and gravity, the lubricating oil can quickly move downward on the inner wall of the stamping sleeve, so that the lubricating oil can quickly cover the connection between the stamping sleeve and the retractor guide ring. Since the diameter of the second oil outlet cylinder is smaller than the diameter of the punching block, the direction of the oil outlet of the second oil outlet groove is set upward. When the hydraulic rod is extended and the punching sleeve is pushed through the mounting plate to move close to the reel guide ring, the second oil outlet cylinder is first inserted into the through hole on the surface of the reel guide ring, and lubricating oil is sprayed on the upper part of the inner wall of the through hole. Under the action of gravity, the lubricating oil flows downward, thereby quickly and evenly filling the through hole on the surface of the reel guide ring, increasing the spraying area of ​​the lubricating oil, thereby further ensuring the processing efficiency and the quality of the finished product.

[0021] 3. The punching and oiling system of the automobile seat belt retractor is provided with a driving assembly and a roller. With the cooperation of the second telescopic rod, the pushing ring, the driving frame and the wedge block, when the punching sleeve and the punching block cooperate with each other to perform the punching and flanging process on the retractor guide ring, the pushing ring first contacts with the surface of the retractor guide ring. With the continuous punching and flanging, the wedge block can push the tooth plate to move away from the wedge block, so that the rotating base automatically drives the first oil outlet cylinder and the second oil outlet cylinder to rotate, and the linkage effect does not require the operator to perform additional operations, thereby improving the operator's convenience of use. Under the action of the roller, the friction force when the wedge block pushes the tooth plate to move is reduced, thereby ensuring the stability of the movement of the device.

The oil inlet of the oil pump body 501 is interconnected with the external oil supply tank through the oil inlet hose 503. When the oil pump body 501 is working, the lubricating oil in the external oil supply tank enters the first oil outlet cylinder 405 and the second oil outlet cylinder 406 through the oil inlet hose 503 and the three-way hose 502. The oil is discharged from the inside through the first oil outlet groove 407 and the second oil outlet cylinder 406. The diameter of the first oil outlet cylinder 405 is the same as the inner diameter of the stamping sleeve 302. The oil outlet of the first oil outlet groove 407 is directed downward, and the oil outlet of the second oil outlet groove 408 is directed upward. By setting the first oil outlet groove 407 and the second oil outlet groove 408, since the diameter of the first oil outlet cylinder 405 is the same as the inner diameter of the stamping sleeve 302, when the first oil outlet cylinder 405 is retracted into the stamping sleeve 302, the first oil outlet cylinder 405 and the stamping sleeve 302 are The inner wall is tightly fitted, and the direction of the oil outlet of the first oil outlet groove 407 is set downward, so that after the lubricating oil is sprayed out through the first oil outlet groove 407, under the cooperation of the spray force and gravity, the lubricating oil can quickly move downward on the inner wall of the punching sleeve 302, so that the lubricating oil can quickly cover the connection between the punching sleeve 302 and the retractor guide ring 9. Since the diameter of the second oil outlet cylinder 406 is smaller than the diameter of the punching block 104, the direction of the oil outlet of the second oil outlet groove 408 is set upward. When the hydraulic rod 201 is extended When the stamping sleeve 302 is pushed by the mounting plate 202 to move close to the reel guide ring 9, the second oil outlet cylinder 406 is first inserted into the through hole on the surface of the reel guide ring 9, and the lubricating oil is sprayed on the upper part of the inner wall of the through hole to increase the spraying area of ​​the lubricating oil. Under the action of gravity, the lubricating oil flows downward, thereby evenly filling the through hole on the surface of the reel guide ring 9, thereby further ensuring that when the punching block 104 punches and flanging the through hole, the lubricating oil can completely cool down and avoid burrs.

[0051] In the present invention, the driving assembly 8 includes at least one second telescopic rod 801 fixedly connected to the outer wall of the mounting sleeve 301, the bottom of the movable rod of the second telescopic rod 801 is fixedly connected to a pushing ring 802, the pushing ring 802 is fixedly connected to a driving frame 803, the top of the driving frame 803 is fixedly connected to a wedge block 804, the end of the toothed plate 603 close to the wedge block 804 is rotatably connected to a roller 7, the roller 7 is rollingly connected to the wedge surface of the wedge block 804, when the wedge block 804 moves close to the mounting plate 202, with the cooperation of the roller 7, the toothed plate 603 pushes the driving gear 601 to rotate, and by arranging the driving assembly 8 and the roller 7, the second telescopic rod 801, the pushing ring 802, With the cooperation of the driving frame 803 and the wedge block 804, when the stamping sleeve 302 and the punching block 104 cooperate with each other to perform punching and flanging processing on the reel guide ring 9, the push ring 802 first contacts the surface of the reel guide ring 9. As the punching and flanging continue, the wedge block 804 can push the tooth plate 603 to move away from the wedge block 804, so that the rotating base 401 automatically drives the first oil outlet cylinder 405 and the second oil outlet cylinder 406 to rotate. The linkage effect does not require additional operation by the operator, thereby improving the operator's convenience of use. Under the action of the roller 7, the friction force when the wedge block 804 pushes the tooth plate 603 to move is reduced, thereby ensuring the stability of the movement of the device.

[0052] Working principle: The operator places the reel guide ring 9 to be processed inside the placement base 101 so that it is located on the surface of the placement plate 102. The hydraulic rod 201 is extended so that the mounting plate 202 drives the punching sleeve 302 to move closer to the placement plate 102. At this time, the push ring 802 first contacts the top of the reel guide ring 9, and the second oil outlet cylinder 406 is inserted into the through hole on the surface of the reel guide ring 9 and fits with the top of the punching block 104. As the hydraulic rod 201 continues to extend, the punching sleeve 302 and the punching block 104 cooperate with each other to perform punching and flanging processing on the reel guide ring 9. At the same time, under the extrusion of the reel guide ring 9, the push ring 802 and the second oil outlet cylinder 406 both move closer to the mounting plate 202, and on the drive frame 803 With the cooperation of , the wedge block 804 pushes the tooth plate 603 to move away from the driving frame 803, and the tooth plate 603 drives the rotating base 401 to rotate through the driving gear 601 and the driven gear 602, so that the rotating base 401 drives the first oil outlet cylinder 405 and the second oil outlet cylinder 406 to rotate through the first mounting cylinder 402 and the second mounting cylinder 403, and the oil pump body 501 works, so that the lubricating oil inside the external oil supply tank enters the first oil outlet cylinder 405 and the second oil outlet cylinder 406 through the oil inlet hose 503 and the three-way hose 502, and then is discharged through the first oil outlet groove 407 and the second oil outlet cylinder 406, so as to evenly spray the lubricating oil on the contact point between the surface of the retractor guide ring 9 and the stamping sleeve 302, and the inside of the through hole of the retractor guide ring 9;

[0053] After the punching sleeve 302 and the punching block 104 punch and flanging the reel guide ring 9, the hydraulic rod 201 contracts to make the mounting plate 202 move away from the placement base 101. The extrusion force on the first oil outlet cylinder 405 is released. Under the elastic force of the second spring 410, the first oil outlet cylinder 405 automatically extends out of the punching sleeve 302, so that the punching sleeve 302 automatically pushes the reel guide ring 9, thereby releasing the connection with the punching sleeve 302 and completing the unloading of the reel guide ring 9. At the same time, under the action of the third spring 607, the tooth plate 603 automatically moves back to its original position, so that the second telescopic rod 801 automatically moves away from the mounting plate 202 until it returns to its original position.
