Lubrication structure for punch press slide guide

Abstract

This utility model discloses a lubrication structure for a punch press slide guide, relating to the field of punch presses. The key technical points are: it includes a machine body, within which a slide block and two guide rails are installed. Oil injection holes are opened on opposite sides of the two guide rails. Oil guide grooves and transverse grooves are also opened on the inner walls of the guide rails. A return oil groove is also opened between adjacent oil guide grooves. Oil guide ropes are installed in both the return oil groove and the transverse groove. After lubricating oil is injected into the oil injection hole, it flows downwards along the oil guide groove. When the lubricating oil reaches the transverse groove, it is absorbed by the oil guide rope within the transverse groove, preventing it from flowing beyond the transverse groove to the next oil injection hole. Furthermore, under the capillary action of the fibers, the lubricating oil in the guide rope flows along the return oil groove. This design ensures that the lubricating oil injected into each oil injection hole does not easily flow to other oil injection hole areas, guaranteeing uniform lubrication.

Description

Technical Field

[0001] This utility model relates to the field of punch presses, and more specifically, it relates to a lubrication structure for a punch press slide guide. Background Technology

[0002] A punch press is a mechanical device that uses pressure to stamp metal or non-metal materials. It is mainly used for processes such as punching, blanking, bending, stretching, and forming. The slide guide is a key component of the punch press, which directly drives the die to complete the stamping action. When the punch press is working, the slide reciprocates. The contact surface between the guide and the slide bears a large amount of pressure and friction. Lubricant can form an oil film on the metal surface, reducing direct contact and the coefficient of friction, thereby extending the service life of the guide and the slide.

[0003] To facilitate the addition of lubricating oil, oil injection holes are provided on the punch press. By injecting lubricating oil into these holes, the lubricating oil can enter between the slider and the guide rail, thus ensuring the smooth sliding of the slider. In order to ensure the uniform distribution of lubricating oil, there are multiple oil injection holes, and several of them are distributed along the length of the guide rail. However, the guide rail is generally vertically distributed. When lubricating oil is injected into the oil injection hole located at the top of the guide rail, the lubricating oil will flow downward under the action of gravity, resulting in a relatively small amount adhering to the corresponding friction surface. Furthermore, the lost lubricating oil will enter the area of ​​other oil injection holes, making the overall lubricating oil distribution of the guide rail still unsatisfactory.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lubrication structure for a punch press slide guide.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a lubrication structure for a punch press slide guide rail, comprising a machine body, wherein a slide block and two guide rails are provided in the machine body, the slide block is slidably connected between the two guide rails, and each of the two guide rails has a plurality of oil injection holes communicating with the outer wall of the machine body on one side facing each other. An oil guide groove communicating with the oil injection holes is provided on the inner wall of the guide rail, one end of the oil guide groove extends to the top of the next oil injection hole, and a transverse groove is also provided on the inner wall of the guide rail. The transverse groove is connected to the end of all the oil guide grooves facing away from the oil injection holes, and a return oil groove is also provided between two adjacent oil guide grooves. One end of the return oil groove is connected to the transverse groove, and an oil guide rope is provided in both the return oil groove and the transverse groove.

[0007] The present invention is further configured such that when the oil guide rope is in a dry state, the oil guide rope is located in the transverse groove and the return oil groove.

[0008] The present invention is further configured such that: the oil injection hole includes a mounting hole and an oil guide channel, the diameter of the mounting hole is larger than the diameter of the oil guide channel, and a sealing block is threadedly connected in the mounting hole.

[0009] The present invention is further configured such that the path of the oil guide channel is inclined upward.

[0010] The present invention is further configured such that the upward tilt angle of the oil guide channel is 30-40 degrees.

[0011] The present invention is further configured such that a butterfly-shaped piece is provided on one side of the closed block.

[0012] In summary, this utility model has the following beneficial effects:

[0013] After the lubricating oil is poured into the oil injection hole, it flows downward along the oil guide groove. When the lubricating oil reaches the horizontal groove, it is absorbed by the oil guide rope inside the horizontal groove, preventing it from flowing beyond the horizontal groove to the area of ​​the next oil injection hole. Furthermore, under the capillary action of the fibers, the lubricating oil in the oil guide rope flows along the return oil groove, which is located between two adjacent oil guide grooves. This ensures that the friction area around the return oil groove is also lubricated, thus guaranteeing the lubrication effect of the lubricating oil. Through this design, the lubricating oil injected into each oil injection hole is less likely to flow to other oil injection hole areas, ensuring the uniformity of lubrication.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Lubrication structure for punch press slide guide, such as Figure 1 and Figure 2As shown, the device includes a body 1, inside which is a slider 2 and two guide rails 3. The slider 2 is slidably connected between the two guide rails 3. Several oil injection holes communicating with the outer wall of the body 1 are provided on opposite sides of the two guide rails 3. The slider 2 moves up and down along the length of the guide rails 3, thereby driving the mold to complete the pressing action. When there is insufficient lubrication between the slider 2 and the guide rails 3, oil is injected into each oil injection hole to improve the smoothness of the slider 2's sliding. Oil guide grooves 4 communicating with the oil injection holes are provided on the inner wall of the guide rails 3. One end of the oil guide groove 4 extends above the next oil injection hole. A transverse groove 5 is also provided on the inner wall of the guide rails 3, communicating with the ends of all the oil guide grooves 4 facing away from the oil injection holes. A return oil groove 6 is also provided between two adjacent oil guide grooves 4, one end of which communicates with the transverse groove 5. Oil guide ropes 7 are provided in both the return oil groove 6 and the transverse groove 5. After being injected into the oil injection hole, the lubricating oil flows downward along the oil guide groove 4. When the lubricating oil flows to the position of the transverse groove 5, it is absorbed by the oil guide rope 7 in the transverse groove 5, so that the lubricating oil does not easily flow beyond the transverse groove 5 to the area of ​​the next oil injection hole. Under the capillary action of the fibers, the lubricating oil in the oil guide rope 7 flows along the return oil groove 6. The return oil groove 6 is located between two adjacent oil guide grooves 4, so that the friction area around the return oil groove 6 can also be lubricated, thus ensuring the lubrication effect of the lubricating oil. With this setting, the lubricating oil injected into each oil injection hole does not easily flow to other oil injection hole areas, ensuring the uniformity of lubrication. The core filament of the oil guide rope 7 is made of twisted cotton fiber, and the outer filament of the oil guide rope 7 is made of twisted polyester fiber. The outer filament is wrapped around the core filament. Polyester fiber is wear-resistant and temperature-resistant, with a long service life, while cotton fiber ensures the oil absorption capacity of the oil guide rope 7.

[0020] like Figure 2 and Figure 3As shown, when the oil guide rope 7 is dry, it is located in the transverse groove 5 and the return oil groove 6. Normally, the oil guide rope 7 is located within these grooves, thus not affecting the reciprocating motion of the slider 2. After oil is added, the oil guide rope 7 absorbs the lubricating oil, causing it to expand and protrude from the transverse groove 5 and the return oil groove 6. During the reciprocating motion of the slider 2, the oil guide rope 7 is squeezed, thus forcing out the lubricating oil and lubricating the area around the return oil groove 6. The oil filling hole includes a mounting hole 8 and an oil guide channel 9. The diameter of the mounting hole 8 is larger than the diameter of the oil guide channel 9. A sealing block 10 is threaded into the mounting hole 8. When oil is added, the sealing block 10 is threaded into the mounting hole 8, thereby... The opening of the oil injection hole is sealed to reduce the entry of debris. Two butterfly-shaped plates 11 are provided on one side of the sealing block 10. By applying force to the butterfly-shaped plates 11, the sealing block 10 can be rotated. The butterfly-shaped plates 11 make it easy to apply force to the sealing block 10. The path of the oil guide channel 9 is inclined upward, so that during the oil injection process, people can use gravitational potential energy to reduce the speed at which the lubricating oil is sprayed out of the oil injection hole, so that the lubricating oil can flow along the oil guide groove 4. The upward inclination angle of the oil guide channel 9 is 30 degrees to 40 degrees. In this embodiment, the upward inclination angle of the oil guide channel 9 is 30 degrees. This setting ensures that the inclination angle of the oil guide channel 9 is not too large, and the return speed of the lubricating oil after the oil injection is completed is not too fast, which makes it convenient for people to handle.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
