Description

Technical Field

[0001] This utility model relates to the field of oil seal skeleton processing, and in particular to a punching and drilling device used in oil seal skeleton processing. Background Technology

[0002] The skeleton oil seal is a typical example of an oil seal, and the term "oil seal" generally refers to the skeleton oil seal. The function of an oil seal is typically to isolate lubricated components in a transmission system from the external environment, preventing lubricant leakage. The skeleton acts like the reinforcing steel in a concrete structure, providing reinforcement and maintaining the seal's shape and tension. Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces of the desired shape and size.

[0003] During the processing of oil seal skeletons using stamping technology, there is often a need to replace the punches. However, the punch replacement operation in existing machines is very cumbersome, and it often takes workers a long time to complete the replacement, which affects production efficiency to some extent. At the same time, after each stamping operation, workers need to remove the stamped oil seal skeleton, but because it is located inside the mold, it is not convenient to remove it directly, which also affects production efficiency.

[0004] In response to this technical problem, this application proposes a punching and drilling device for processing oil seal skeletons. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology by proposing a punching and drilling device for processing oil seal skeletons. The punch can be easily replaced by the fixing component, and the processed oil seal skeleton can be easily removed by the lifting component.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A punching and drilling device for processing oil seal skeletons includes a base. Support columns are fixedly connected to the front and rear ends of the left and right sides of the top of the base. A top seat is fixedly connected to the top of the support columns. A hydraulic cylinder is installed on the upper end of the top seat. A lower die seat is fixedly connected to the middle of the top of the base. A mold is fixedly connected to the middle of the top of the lower die seat. An ejection mechanism is provided in the lower die seat. Slide rods are fixedly connected to the left and right ends of the top of the lower die seat. An upper die seat is slidably connected to the top of the slide rods. The top of the upper die seat is connected to the drive end of the hydraulic cylinder. A punch is connected to the middle of the bottom side of the upper die seat through a fixing component. A scrap groove is provided in the base. A baffle is rotatably connected to the scrap groove near the rear end of the base.

[0008] Furthermore, the ejection mechanism includes a main liquid tank located in the middle of the lower mold base, an auxiliary liquid tank evenly distributed around the upper end of the main liquid tank, an ejector rod slidably connected to the inner side of the auxiliary liquid tank, a limit rod fixedly connected to the top of the auxiliary liquid tank, and a pushing component provided on the side of the main liquid tank near the front end of the lower mold base.

[0009] Furthermore, the number of auxiliary liquid tanks is three.

[0010] Furthermore, a piston rod is slidably connected to the inner side of the main liquid tank of the pushing component, a limit ring is fixedly connected to the inner wall of the main liquid tank, a piston top is fixedly connected to one end of the piston rod, and a handle is fixedly connected to the other end of the piston rod.

[0011] Furthermore, a spring is sleeved on the outer wall of the slide rod, with one end of the spring connected to the upper mold base and the other end connected to the lower mold base.

[0012] Furthermore, the fixing component includes a locking disc, the top of which is fixedly connected to the upper mold base. Axial sliding grooves are formed on both sides of the inner wall of the locking disc, and circumferential sliding grooves are formed on both sides of the inner wall of the top of the locking disc. The circumferential sliding grooves communicate with the top of the axial sliding grooves. A locking hole is formed on the side wall of the locking disc. Protrusions are fixedly connected to both sides of the top of the punch. Alignment holes are formed on both sides of the punch near the protrusions. Locking pins are inserted into the locking hole and the alignment hole. A limiting groove is formed on the inner side of one end of the locking pin, and a spring and a pop-out pin are provided inside the limiting groove.

[0013] Furthermore, the axis of the locking hole is perpendicular to the horizontal plane where the circumferential groove is located.

[0014] Furthermore, the number of the axial groove, the circumferential groove, and the locking hole are all two.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the circumferential sliding groove and the axial sliding groove on the inner side of the lock disc make the disassembly and assembly of the punch easier, and the punch can be replaced quickly without tools. At the same time, the locking pin further fixes the punch, and the locking pin can also be quickly disassembled and assembled without tools. This reduces the difficulty of operation for workers and thus improves production efficiency.

[0017] 2. In this utility model, when the handle is pushed, pressure can be applied to the hydraulic oil in the liquid tank, thereby pushing the push rod. At the same time, the limiting rod will limit the height of the push rod. The already stamped oil seal skeleton will be pushed out of the mold groove to a suitable height, so that the workers can take out the skeleton more quickly and conveniently, thereby improving production efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] One embodiment of this utility model is provided:

[0031] Reference Figure 1 and Figure 8 A punching and drilling device for processing oil seal skeletons includes a base 1. Support columns 2 are fixedly connected to the front and rear ends of the left and right sides of the top of the base 1. A top seat 7 is fixedly connected to the top of the support columns 2. A hydraulic cylinder 8 is installed on the upper end of the top seat 7. A lower die seat 3 is fixedly connected to the middle of the top of the base 1. A mold 11 is fixedly connected to the middle of the top of the lower die seat 3. An ejection mechanism is provided in the lower die seat 3. Slide rods 4 are fixedly connected to the left and right ends of the top of the lower die seat 3. An upper die seat 6 is slidably connected to the top of the slide rods 4. The top end of the upper die seat 6 is connected to the drive end of the hydraulic cylinder 8. A punch 10 is connected to the lower end of the upper die seat 6 through a fixing component. A scrap groove 13 is provided in the base 1. A baffle 14 is rotatably connected to the scrap groove 13 near the rear end of the base 1.

[0032] Reference Figure 2 , Figure 3 ,and Figure 4 The main liquid tank 25 is located in the middle of the lower mold base 3. Auxiliary liquid tanks 27 are evenly distributed around its upper end. The inner side of the auxiliary liquid tanks 27 is slidably connected to the ejector rods 24. There are three auxiliary liquid tanks 27 and three ejector rods 24. The top of the auxiliary liquid tanks 27 is fixedly connected to the limit rods 26. The main liquid tank 25 has an interface for pushing on the side near the front end of the lower mold base 3. The inner side of the main liquid tank 25 is slidably connected to the piston rod 28. The inner wall of the main liquid tank 25 is fixedly connected to the limit ring 30. One end of the piston rod 28 is fixedly connected to the piston top 29, and the other end of the piston rod 28 is fixedly connected to the handle 12. When it is necessary to eject the stamped oil seal skeleton, by pushing the handle 12, the piston will compress the hydraulic oil in the main liquid tank 25 and transmit the pressure to each auxiliary liquid tank 27, pushing the ejector rods 24 to move upward synchronously, and smoothly pushing the oil seal skeleton away from the mold 11, effectively preventing the skeleton from deforming and making it easy for the staff to handle.

[0033] Reference Figure 1A spring 5 is fitted on the outer wall of the slide rod 4. One end of the spring 5 is connected to the upper die base 6, and the other end is connected to the lower die base 3. When the upper die base 6 drives the punch 10 to move downward for stamping, the spring 5 is compressed and stores energy. When the stamping is completed and the pressure of the hydraulic cylinder 8 is removed, the spring 5 releases the stored energy and pushes the upper die base 6 to quickly and smoothly return to its original position along the slide rod 4. This spring 5 effectively buffers the impact force during the stamping process, reduces equipment vibration and noise, improves the service life of the mold 11 and the equipment, and ensures the timeliness and reliability of the reset action.

[0034] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 The top of the locking disc 9 is fixedly connected to the upper mold base 6. Axial grooves 19 are provided on both sides of the inner wall of the locking disc 9. Circumferential grooves 17 are provided on both sides of the inner wall of the top of the locking disc 9, and the circumferential grooves 17 are connected to the top of the axial grooves 19. Locking holes 18 are provided on the side wall of the locking disc 9. The axis of the locking holes 18 is perpendicular to the horizontal plane where the circumferential grooves 17 are located. There are two axial grooves 19, two circumferential grooves 17, and two locking holes 18, which are arranged symmetrically. Protrusions 15 are fixedly connected to both sides of the top of the punch 10. Alignment holes 21 are provided on both sides of the punch 10 near the protrusions 15. The locking pin 16 can be inserted into the locking holes 18 and the alignment holes 21 to prevent rotation and loosening. A limit groove 23 is provided on the inner side of one end of the locking pin 16. A spring 22 and a pop-out pin 20 are provided on the inner side of the limit groove 23.

[0035] Specifically, when replacing the punch 10, first align the protrusion 15 at the top of the punch 10 with the axial groove 19 on the lock disc 9 and insert it until the protrusion 15 reaches the top of the axial groove 19. Then rotate the punch 10 at a certain angle so that the protrusion 15 slides along the circumferential groove 17 to the locking position. At this time, the alignment hole 21 on the punch 10 is aligned with the locking hole 18 on the lock disc 9. Insert the locking pin 16 into the locking hole 18 from one side of the lock disc 9 and pass through the alignment hole 21. The spring 22 inside the locking pin 16 will always push the ejector pin 20 outward so that it is stuck on the other side of the lock disc 9 to prevent the locking pin 16 from accidentally falling off during vibration and to ensure reliable locking. When disassembly is required, apply pressure to the ejector pin 20 to press it into the locking pin 16. At this time, the locking pin 16 can be pulled out, and the punch 10 can be rotated in the opposite direction to remove it along the axial groove 19.

[0036] Working principle: The blank is placed into the mold 11, and the hydraulic cylinder 8 is started. The hydraulic cylinder 8 applies downward pressure, causing the upper mold base 6 to move downward along the slide rod 4. The punch 10 simultaneously moves downward to complete the punching. At this time, the scrap material slides down the scrap groove 13 to the rear side of the platform 1 and falls into the collection container. Due to the presence of the baffle 14, the impact force of the scrap material can be reduced to prevent injury. At the same time, after the hydraulic cylinder 8 stops applying pressure, the spring 5 rebounds and pushes the upper mold base 6 to reset upward. When taking out the processed oil seal skeleton, the operator pushes the handle 12 to apply pressure to the main liquid tank 25. The pressure of the main liquid tank 25 is transmitted to the auxiliary liquid tank 27 to push the ejector rod 24 upward and push the oil seal skeleton away from the mold 11. At this time, the operator can quickly and easily take out the oil seal skeleton. When replacing the punch 10, the operator simultaneously presses the pop-out pins 20 on both sides of one end of the locking pin 16 with one hand, pressing it into the inside of the locking pin 16, and pulls it out from the other end of the locking pin 16 with the other hand. The punch 10 is rotated in the opposite direction until the protrusion 15 of the punch 10 is aligned with the axial groove 19 on the inner wall of the lock disc 9. Then, the punch 10 is removed downwards. The replacement punch 10 is then inserted into the lock disc 9 along the axial groove 19. The punch 10 is rotated until the locking hole 18 and the alignment hole 21 are aligned. The pop-out pin 20 at one end of the locking pin 16 is then pressed, and the locking pin 16 is inserted and passes through the locking hole 18 and the alignment hole 21. The pop-out pin 20 will automatically pop out and lock the locking pin 16. At this point, the replacement of the punch 10 is completed.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
