Description

Technical Field

[0001] The present invention relates to the field of metal stamping, and more particularly to a slotted bushing integrated processing device with a self-adaptive adjustment function. Background Art

[0002] A slotted bushing is a special mechanical fastener or positioning element, which is usually a hollow cylinder with a slot running through its entire length. The presence of this slot makes the bushing elastic and can be compressed or expanded in the radial direction (diameter direction).

[0003] Currently, the processing of slotted bushings mostly uses stamping equipment. For example, the Chinese invention patent application with publication number CN119897395A discloses a slotted bushing processing equipment. Through the mutual cooperation between multiple punches on the stamping equipment, the material is rolled into a round shape to form a slotted bushing. However, this processing equipment can only produce products with smaller diameters and thinner thicknesses. For products with larger diameters and requiring a certain thickness, traditional stamping dies are still required for production. The processing method of the stamping die is to bend the metal sheet through the upper die so that the two ends of the metal sheet are bent downward, and then the lower die is controlled to lift and perform a secondary shaping on the bent metal sheet to form a hollow cylinder. In this process, when the two ends of the metal sheet that have been bent once come into contact with the inner wall of the die cavity of the lower die, the two ends of the metal sheet rub against the inner wall of the die cavity of the lower die under high pressure (especially the gap forming area). As the number of stamping times increases, scratches and cracks are easily generated on the relative sliding surface of the lower die cavity, resulting in scratches or deformation on the surface of the die cavity, shortening the life of the die and requiring frequent replacement or repair. Summary of the Invention

The other ends of the plurality of connecting rods are fixedly connected to one side of the insert, and a avoidance groove for accommodating the cylinder three is provided inside the base.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) This solution is provided with a lubricating and anti-friction part, through which lubricating oil can be sprayed onto the inner mold cavity of the lower die head. The lubricating oil forms a fluid dynamic pressure oil film on the inner wall of the mold cavity, converting the direct solid contact between the metal sheet and the mold into oil film shearing, avoiding scratches and reducing the tearing and peeling of the mold surface material. At the same time, it can also prevent local stress from exceeding the mold fatigue limit, extend the service life of the mold, and reduce production costs.

[0019] (2) This solution is provided with a pressing die head and a pressing arc surface. Before the upper die head bends the metal sheet, the two ends of the metal sheet are first slightly bent by the cooperation of the pressing die head and the pressing arc surface. In this way, when the upper die head bends the metal sheet, the ends of the metal sheet bent by the upper die head and facing the two ends of the lower die head are arc-shaped with a certain inward angle, and will not appear vertical. When contacting the lower die, it is converted into a gradual sliding, which reduces the stress peak and avoids the stress of the corners of the mold cavity exceeding the limit. At the same time, it can also avoid the damage to the mold cavity in the lower die head caused by the two ends of the metal sheet being in a vertical state.

[0020] (3) This scheme is provided with an inward-retracting anti-wear component. When the two ends of the metal plate are subjected to a small-amplitude bending process by the cooperation of the edge pressing die head and the edge pressing arc surface, the inward-retracting die head is driven to move by the work of the second cylinder, so that the inward-retracting die head moves toward the end of the metal plate and presses the end of the metal plate into the inward-retracting groove. On the basis of the small-amplitude bending process of the metal plate, the end of the metal plate is subjected to an inward-retracting process. When the metal plate subjected to the inward-retracting process is bent by the upper die head, the end sections of the metal plate will not contact the inner mold cavity of the lower die head. Instead, the bent outer arc surfaces of the two ends of the metal plate contact the inner mold cavity of the lower die head. The friction area is expanded from "point / line" to only the side of the plate in contact with the mold cavity curved surface, which greatly reduces the wear area and makes the local bending of the end head smooth. In the subsequent large bending, the stress is distributed on a larger curved surface, avoiding micro cracks or hardening on the edge of the section, reducing scratches and micro-chip defects, and greatly reducing the frequency of mold repair and polishing, thereby ensuring production continuity and capacity.

The mold core 3 is fixedly connected to one side of the protrusion 9.

[0037] The pushing assembly 44 includes a pushing seat 441 slidingly connected to the upper end of the material receiving seat 43, a connecting plate 443 slidingly connected in the through groove 431 and with the upper end fixedly connected to the lower end of the pushing seat 441, a movable seat 442 slidingly connected inside the material receiving seat 43 and fixedly connected to the lower end of the connecting plate 443, and a pushing rod 444 fixedly connected to one side of the connecting plate 443 and movably inserted into the rod groove 46. A cylinder 45 is fixedly connected to one side of the material receiving seat 43, and the telescopic end of the cylinder 45 passes through the interior of the material receiving seat 43 and is fixedly connected to the movable seat 442.

[0038] The core 3, the edge pressing die 8, the upper die 16 and the lower die 19 are all provided with flow channels inside. The two sides of the edge pressing die 8, the upper die 16 and the lower die 19 are respectively provided with a liquid inlet 6 connected to the flow channel and a liquid outlet 7 connected to the flow channel. One side of the core 3 is provided with a liquid inlet 31 connected to the flow channel, and one side of the protrusion 9 is provided with a liquid outlet 32 ​​connected to the flow channel in the core 3. The core 3, the edge pressing die 8, the upper die 16 and the lower die 19 are all embedded with temperature sensors.

[0039] By adopting the above technical solution, before the metal sheet is press-bent, the control motor 1 23 is controlled to drive the screw rod 24 to rotate, and the rotation of the screw rod 24 drives the slide 22 to move in the slide groove 21, and the movement of the slide 22 drives the seat body 25 to move toward the direction of the feed component 4, and the hollow rod 27 can enter between the lower die head 19 and the mold core 3. The input end of the rotary joint 26 is externally connected to the liquid supply pipe. The lubricating liquid in the liquid supply pipe can enter the interior of the hollow rod 27 from the rotary joint 26 and be sprayed out from the nozzle 271. The lubricating liquid is sprayed on the inner wall of the cavity of the lower die head 19, and the motor 2 251 is driven to rotate the gear 2 29. The rotation of the gear 2 29 drives the gear 1 28, the inner tube of the rotary joint 26, and the hollow rod 27 to rotate, so that the nozzle 271 rotates towards the lower die head 19. The inner wall of the die head 19 cavity is lubricated in multiple areas, and the lubricating liquid forms a fluid dynamic pressure oil film on the inner wall of the cavity, which converts the direct contact between the metal sheet and the solid of the mold into oil film shearing, avoids scratches, reduces the tearing and peeling of the mold surface material, and at the same time avoids local stress exceeding the fatigue limit of the mold, prolongs the service life of the mold, and reduces production costs. The metal sheet reaches the material receiving seat 43 from the feed trough 42, and the cylinder 45 extends and drives the movable seat 442 to move. The movable seat 442 moves through the connecting plate 443 to drive the pusher seat 441 to move. The pusher seat 441 moves to push the metal sheet on the material receiving seat 43 to move. After the metal sheet is pushed to the top of the protrusion 9, the cylinder 45 contracts and drives the pusher seat 4 41 moves and resets, and the next metal sheet passes through the feed chute 42 and reaches the material receiving seat 43, then the cylinder 1 45 pushes the metal sheet to the top of the protrusion 9 and this metal sheet will push the previous metal sheet to move, so that the metal sheet previously located above the protrusion 9 moves to the top of the die core 3, and the hydraulic cylinder 1 15 works to drive the upper pressure seat 14 to descend, and the descent of the upper pressure seat 14 drives the upper die head 16 to descend, and the upper die head 16 descends to perform a press bending process on the metal sheet on the die core 3, so that the two ends of the metal sheet are bent downward, and after one bending is completed, the hydraulic cylinder 15 resets, and the hydraulic cylinder 2 17 works to drive the lower pressure seat 18 and the lower die head 19 to rise, and the metal sheet bent downward is subjected to a secondary press bending process by the lower die head 19, The two ends of the material bent downward are bent and fit into the mold core 3, thereby forming a hollow cylinder (slit bushing), and there is a gap running through the entire length of the cylinder (the gap is the joint at both ends of the metal plate). After the secondary bending process is completed, the hydraulic cylinder 2 17 is reset, and at this time the cylinder 1 45 works and extends to drive the pushing seat 441 to push the next metal plate to the top of the protrusion 9, and the ejecting rod 444 on one side of the movable seat 1 442 extends from the rod groove 46, and the product formed and circled on the outside of the mold core 3 is ejected by the ejecting rod 444 to realize unloading. In actual production, a unloading guide tray can be set below the mold core 3 and above the seat body 25, so that the product ejected from the mold core 3 can fall into the storage frame along the unloading guide tray;Liquid inlet 1 31, liquid inlet 2 6, liquid outlet 1 32, and liquid outlet 2 7 are all connected to external water pipes. Temperature sensors can detect the temperature of the mold core 3, the edge holder die 8, the upper die 16, and the lower die 19, monitoring the thermal expansion effect caused by high-speed molding or high-frequency operation in real time. When the temperature is too high, cooling water from liquid inlet 1 31 and liquid inlet 2 6 enters the flow channel to cool the mold core 3, the edge holder die 8, the upper die 16, and the lower die 19. The water in the flow channel is discharged through liquid outlet 1 32 and liquid outlet 2 7 to prevent mold gap distortion caused by thermal expansion. Temperature monitoring and dynamic thermal management counteract thermal expansion effects and achieve adaptive adjustment function during the stamping process.

[0040] like Figure 4 As shown, it also includes two material limiting parts 5 connected to one side of the material receiving seat 43, and the material limiting part 5 includes a limiting plate 51 located on one side of the material receiving seat 43, a positioning bolt 52 passing through the limiting plate 51 and screwed into the inside of the material receiving seat 43, a screw 53 fixed to one side of the limiting plate 51, a limiting disk 54 sleeved on the outside of the screw 53, and a positioning nut 55 screwed onto the outside of the screw 53 and limiting the limiting disk 54.

[0041] The protruding portion 9 is provided with a pressing arc surface 91 on both sides, and a pressing die head 8 is fixedly connected to the lower end of the upper pressing seat 14 .

[0042] By adopting the above technical solution, the metal sheet on the protrusion 9 can be limited by the limiting plate 51 to prevent part of the metal sheet from moving above the mold core 3 when the pusher seat 441 pushes the metal sheet. The metal sheet on the mold core 3 can be limited by the limiting plate 54 to prevent part of the metal sheet from moving out of the mold core 3. When the hydraulic cylinder 15 works to drive the upper die head 16 to descend and perform a bending process on the metal sheet above the mold core 3, the edge pressing die head 8 at the bottom of the upper pressure seat 14 can perform a small bending process on the two ends of the metal sheet located on the protrusion 9. After the small bending process, the metal sheet is bent by the upper die head 16 and the ends facing the two ends of the lower die head 19 are arcs with a certain inward angle, and will not present a vertical state. When it contacts the lower die head 19, it is converted into a gradual sliding in, reducing the stress peak and avoiding the stress of the mold cavity corners exceeding the limit. At the same time, it can also avoid the damage caused by the two ends of the metal sheet being in a vertical state to the inner mold cavity of the lower die head 19.

[0043] like Figure 6As shown, two inward-retracting grooves 92 are symmetrically provided on both sides of the protrusion 9, and two inward-retracting anti-wear components 10 are symmetrically connected to one side of the material receiving seat 43, and the inward-retracting anti-wear component 10 includes a cylinder 2 101 fixedly connected to the inside of the material receiving seat 43, a side plate 102 fixedly connected to one side of the material receiving seat 43, two movable grooves 103 respectively provided on one side of the side plate 102 and one side of the material receiving seat 43, two guide rods 104 respectively fixed in the two movable grooves 103, an inward-retracting die head 105 slidably connected in the two movable grooves 103 and movably sleeved on the outside of the two guide rods 104, and the telescopic end of the cylinder 2 101 is fixedly connected to one side of the inward-retracting die head 105.

[0044] By adopting the above technical solution, when the edge pressing die head 8 descends and performs a small bending process on the two ends of the metal plate, the control cylinder 2 101 is extended to drive the inward die head 105 to move toward the inward groove 92, and the two ends of the metal plate are pressed into the inward groove 92 by the inward die head 105. On the basis of the small bending process of the metal plate, the end of the metal plate is inwardly bent. When the metal plate that has been inwardly bent is bent once by the upper die head 16 and is about to be bent for the second time by the lower die head 19, the metal plate The two end sections of the metal plate will not contact the inner mold cavity of the lower die head 19. Instead, the bent outer arc surfaces at both ends of the metal plate will contact the inner mold cavity of the lower die head 19. The friction area is expanded from "point / line" to only the side of the plate in contact with the curved surface of the mold cavity, which greatly reduces the wear area and makes the local bending of the end smooth. During subsequent large bending, the stress is distributed on a larger curved surface, avoiding micro cracks or hardening on the edge of the section, reducing scratches and micro chipping defects, and greatly reducing the frequency of mold rework and polishing, thereby ensuring production continuity and capacity.

[0045] like Figure 6-Figure 8 As shown, a groove is provided on the inner wall of the lower die head 19, and an insert 204 is inserted in the groove. Two closing components 20 are also symmetrically connected inside the lower die head 19, and the closing component 20 includes a cylinder three 201 fixedly connected to the inside of the lower pressure seat 18, a movable seat two 202 slidingly connected to the inside of the lower die head 19, and a plurality of connecting rods 203 fixedly connected to one side of the movable seat two 202. The other ends of the plurality of connecting rods 203 are fixedly connected to one side of the insert 204, and a avoidance groove 205 for accommodating the cylinder three 201 is provided inside the base 11.

[0046] By adopting the above technical solution, when the lower die head 19 rises to perform secondary bending on the two ends of the metal sheet, the two ends of the metal sheet gradually slide into the cavity of the lower die head 19. When the two ends of the metal sheet slide to the position of the insert 204, the hydraulic cylinder 2 17 stops working, and the cylinder 3 201 extends to drive the movable seat 202 to move. The movable seat 202 moves and drives the insert 204 to move through the connecting rod 203. The insert 204 is ejected from the cavity of the lower die head 19 and pushes the two ends of the metal sheet toward the mold core 3 to bend, actively pushing the folded end to form a wrapped arc that is closer to the mold core 3. Then, the cylinder 3 201 drives the insert 204 to reset and then the lower die head 19 completes the final secondary shaping as a whole. The insert 204 is ejected in stages and guides the bending. The contact direction changes from sliding to pure extrusion / flanging, thereby avoiding wear caused by sliding between the end and the mold cavity.

[0047] Working principle: Before the metal sheet is press-bent, the motor 1 23 is controlled to drive the hollow rod 27 to move. The hollow rod 27 enters between the lower die 19 and the die core 3. The nozzle 271 sprays lubricating liquid on the inner wall of the cavity of the lower die 19. The motor 251 drives the inner tube of the rotary joint 26 and the hollow rod 27 to rotate, so that the nozzle 271 performs multi-area lubrication on the inner wall of the cavity of the lower die 19. After the lubrication is completed, the motor 1 23 drives the hollow rod 27 to move and reset, and the metal sheet is bent. When the feeding chute 42 reaches the receiving seat 43, the cylinder 1 45 extends out and drives the movable seat 1 442 to move. The movable seat 1 442 moves through the connecting plate 443 to drive the pushing seat 441 to move. The pushing seat 441 moves and pushes the metal sheet on the receiving seat 43 to move. After the metal sheet is pushed to the top of the protrusion 9, the cylinder 1 45 contracts and drives the pushing seat 441 to move and reset. The next metal sheet passes through the feeding chute 42 and reaches the receiving seat 43.
