Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a high-precision stamping mold for bearing cover plates. Background Technology
[0002] In modern industrial production, bearings are indispensable key components in various mechanical equipment, and their performance directly affects the overall operational stability and reliability of the equipment. Bearing cover plates, as an important part of bearings, not only protect the internal structure of the bearing from external impurities, but also play a crucial role in maintaining the internal lubrication environment and operational precision of the bearing.
[0003] A search revealed Chinese Patent Publication No. CN221983696U, which discloses a high-precision continuous stamping die for gaskets. The die includes an upper die base and a lower die base, both equipped with a die for gasket forming and several positioning modules. A guiding mechanism is provided between the upper and lower die bases. The upper die base has symmetrically arranged buffer structures, and the lower die base has lubrication mechanisms on both sides. A heat dissipation mechanism is located below the die on the lower die base, and the lower die base also has a feeding mechanism and a discharging mechanism for continuous conveying. The heat dissipation mechanism significantly reduces the temperature of the workpiece and the die, ensuring the accuracy of the stamping process and the yield rate. The condenser tubes inside the heat dissipation box are kept at a low temperature by injecting coolant, and a cooling fan at the bottom blows cool air into the die cavity. Simultaneously, the positioning modules located on the upper and lower die bases significantly improve the accuracy of the stamped workpiece during the stamping process of the punch and die.
[0004] The aforementioned patent specification mentions that "heat dissipation increases the precision of impact." While the patent increases precision through heat dissipation, the opening and closing speed of the die is limited, and the automation level in feeding and unloading is low, requiring frequent manual intervention. This not only increases labor costs but also limits the improvement of production speed. Therefore, a high-precision stamping die for bearing cover plates is proposed to solve the above problems.

[0025] Example 1
[0026] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a high-precision stamping die for a bearing cover, comprising a base 1, a connecting plate 2 fixedly connected to the bottom of the base 1, the connecting plate 2 serving as a connection and transition, organically combining the base 1 with components such as a pneumatic cylinder 3, the top of the connecting plate 2 fixedly connected to a pneumatic cylinder 3 serving as a power source, and a sliding plate 20 fixedly connected to its drive end, the pneumatic cylinder 3, after starting, can drive the sliding plate 20 to slide on the inner wall of the connecting plate 2, providing power support for subsequent stamping actions, the inner wall of the connecting plate 2 is provided with multiple sliding grooves 4, these sliding grooves 4 provide tracks for the sliding of rollers 6, ensuring the stability and accuracy of the die movement, and multiple linkage plates 5 are rotatably connected to both sides of the sliding plate 20;
[0027] The linkage plate 5 can rotate as the slide plate 20 slides, thereby driving the roller 6 to move. Rollers 6 are slidably connected to both sides of the linkage plate 5. The design of the rollers 6 can reduce friction and make the movement of the mold smoother. The outside of one roller 6 is slidably connected to the slide plate 7. When the roller 6 slides in the slide groove 4, it will push up the slide plate 7 to realize the ejection action after stamping. The top of the slide plate 7 is fixedly connected to the support column 3 22. The support column 3 22 plays the role of connection and support. The other end of it is fixedly connected to the top plate 21. The movement of the slide plate 7 drives the top plate 21 to be ejected through the support column 3 22, which can better show the material after stamping. The top of the base 1 is fixedly connected to multiple auxiliary columns 11. The auxiliary columns 11 provide support and sliding track for the lubrication component. The lubrication component is slidably connected to its outside.
[0028] The top of the skateboard 20 is fixedly connected to a support column 18, which serves to connect and transmit force. The other end of the support column 18 is fixedly connected to a top plate 19. When the skateboard 20 slides, the support column 18 drives the top plate 19 to push out, further pushing out the stamped material.
[0029] Four support columns 10 are fixedly connected to the top of the connecting plate 2. The support columns 10 serve as auxiliary and guides. The inside of the slide plate 20 is slidably connected to the outside of the multiple support columns 10. The inside of the slide plate 7 is also slidably connected to the outside of the support columns 10. In this way, during the sliding process of the slide plate 7 and the slide plate 20, the support columns 10 can help them not deviate and ensure the accuracy of the mold stamping action. The bottom of the base 1 is fixedly connected to the top of the support columns 10, which further enhances the stability of the mold structure.
[0030] Example 2
[0031] like Figure 1 , Figure 3 and Figure 4 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to by the same reference numerals as those in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that the lubrication assembly includes an auxiliary block 13. The inner wall of the auxiliary block 13 is slidably connected to the outside of the auxiliary column 11, allowing the auxiliary block 13 to slide smoothly on the auxiliary column 11. Multiple balls 12 are slidably connected to the inner wall of the auxiliary block 13. The design of the balls 12 can further reduce the friction between the auxiliary block 13 and the auxiliary column 11. An oil storage groove 15 is provided on the inner wall of the auxiliary block 13. The outside of the balls 12 is slidably connected to the inner wall of the oil storage groove 15. Each time the fixed plate 14 descends, it will drive the balls 12 to rotate, causing the lubricating oil in the oil storage groove 15 to flow out. This can better lubricate the auxiliary column 11 and the auxiliary block 13, thereby increasing the service time and life of the mold, and improving the stamping accuracy.
[0032] The ball 12 is externally rotatably connected to the outside of the auxiliary column 11. This rotatable design allows the ball 12 to better drive the lubricating oil out. The auxiliary block 13 is externally fixedly connected to a fixing plate 14, which plays the role of fixing and connecting. The bottom of the plate is fixedly connected to a template 19. The template 19 and the template 18 work together to complete the stamping and forming of the bearing cover plate.
[0033] An oil injection pipe 16 is fixedly connected to the top of the auxiliary block 13. The oil injection pipe 16 facilitates the injection of lubricating oil into the oil reservoir 15 to ensure lubrication. A protective cover 17 is slidably connected to the inner wall of the oil injection pipe 16. The protective cover 17 prevents dust and other impurities from entering the oil injection pipe 16 and the oil reservoir 15, ensuring the cleanliness of the lubricating oil, thereby further improving the performance and lifespan of the mold.
[0034] Example 3
[0035] Reference Figures 1 to 3 Another roller 6 is externally slidably connected to the inner wall of the slide 4. This design allows the roller 6 to slide stably in the slide 4, providing reliable support for the lifting action of the first slide plate 7. The second slide plate 20 is externally slidably connected to the inner wall of the connecting plate 2, ensuring that the second slide plate 20 can slide smoothly under the drive of the pneumatic cylinder 3, and ensuring the continuity of the mold action.
[0036] The top of the base 1 is fixedly connected to the template 18, which is one of the key components of stamping. The outer side of the top plate 9 is slidably connected to the inner wall of the template 18, and the outer side of the top plate 21 is slidably connected to the inner wall of the top plate 9. During the stamping process, the ejection action of the top plate 9 and the top plate 21 can smoothly push the stamped material out of the template 18, ensuring the smooth progress of stamping.
[0037] Work steps
[0038] Step 1: Install the mold on the machine. After each impact, the pneumatic cylinder 3 will open, causing the slide plate 20 to slide on the inner wall of the connecting plate 2. Since the two sides of the slide plate 20 are connected to the linkage plate 5, the rollers 6 on both sides of the linkage plate 5 will slide in the groove 4 as the slide plate 20 slides. One of the rollers 6 will lift the slide plate 7. The sliding of the slide plate 20 will drive the top plate 9 to be pushed out through the support column 18. The movement of the slide plate 7 will drive the top plate 21 to be pushed out through the support column 322. This can better show the material after stamping. At the same time, the support column 210 will help the slide plate 7 and the slide plate 20 to not deviate during the sliding process, ensuring the accuracy of the stamping action.
[0039] Step 2: Each time the fixed plate 14 descends, it will drive the auxiliary block 13 to slide down along the auxiliary column 11. The ball bearings 12 on the inner wall of the auxiliary block 13 will rotate. Since the outer surface of the ball bearings 12 is slidably connected to the inner wall of the oil reservoir 15, the rotation of the ball bearings 12 will cause the lubricating oil in the oil reservoir 15 to flow out, better lubricating the contact surface between the auxiliary column 11 and the auxiliary block 13, thereby increasing the service time and life of the mold and improving the stamping accuracy.
[0040] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
