Description

Technical Field

[0001] This utility model belongs to the field of bushing processing technology, and specifically relates to a bushing flanging device. Background Technology

[0002] A bushing is a cylindrical mechanical part that fits onto a rotating shaft and is a component of a sliding bearing. Generally, the bushing has an interference fit with the bearing housing and a clearance fit with the shaft. Depending on its shape and application, bushings can be classified into various types, such as cylindrical bushings, conical bushings, and spherical bushings. Bushings are made from a variety of materials, commonly including metals, polymers, and non-metallic materials. Different materials produce bushings with different performance characteristics, making them suitable for different working environments and conditions. A bushing flanging device is a specialized piece of equipment used for flanging bushings.

[0003] Announcement No. "CN220387577U" discloses a bushing flanging device, relating to the field of bushing processing technology. The device includes a housing, with a first cylinder mounted on the upper surface of the housing. The shaft of the first cylinder faces vertically towards the upper surface of the housing and is fixed with a bushing flanging punch. A positioning cylinder is positioned directly below the bushing flanging punch on the upper surface of the housing. The top of the positioning cylinder has equidistant mounting grooves around its perimeter. A support rod is rotatably mounted within these grooves. One end of the support rod extends to the outside of the positioning cylinder and abuts against the inside of the bushing to be processed. The other end of the support rod extends into the positioning cylinder. A second cylinder is located inside the housing, with a telescopic shaft fixed to its shaft extending into the positioning cylinder. The top of the telescopic shaft is movably connected to the ends of four support rods. This invention allows for the fixing of bushings of different specifications via the positioning cylinder and the extended support rods. The overall structure is simple, requires only one cylinder for control, is low-cost, and facilitates later maintenance.

[0004] Although the aforementioned utility model can fix bushings of different specifications through the positioning cylinder and the unfolded support rod, and the overall structure is simple, requires only one cylinder for control, is low in cost, and is easy to maintain, different bushings require punches and positioning cylinders of different sizes or shapes for flanging operations. Since the bushing flanging punch and the positioning cylinder are fixedly connected, the device can only be used for bushings of specific sizes and shapes, which greatly reduces the versatility and flexibility of the device. Moreover, for manufacturers that need to process a variety of different bushings, it means that a special flanging device needs to be equipped for each type of bushing, which will undoubtedly increase production costs and equipment investment. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a bushing flanging device to solve the problem that different bushings require bushing flanging punches and positioning cylinders of different sizes or shapes for flanging operations. Since the bushing flanging punch and positioning cylinder are both fixedly connected, the device can only be applied to bushings of specific sizes and shapes, which greatly reduces the versatility and flexibility of the device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A bushing flanging device includes a worktable, a fixed frame fixedly connected to one end of the worktable, a first cylinder mounted on the upper end of the fixed frame, a mounting seat fixedly connected to the telescopic end of the first cylinder, a flanging punch movably connected to the bottom end of the mounting seat, a fixed seat fixedly connected to the upper end of the worktable, an assembly seat movably connected to the upper end of the fixed seat, a limit cylinder fixedly connected to the upper end of the assembly seat, a demolding component installed inside the worktable, and assembly blocks symmetrically fixedly connected to the bottom end of the assembly seats, with a fixed component installed inside the assembly blocks.

[0008] The fixing assembly includes a cavity, a return spring, a moving plate, and a locking block. The cavity is located inside the assembly block, with a return spring symmetrically fixed to one end. A moving plate is fixedly fixed to the other end of the return spring, and the moving plate is slidably connected to the cavity. A locking block is fixedly connected to the end of the moving plate away from the return spring, and the locking block extends beyond the side of the assembly block. The bottom of the locking block is beveled. The upper end of the fixing base has symmetrically formed assembly grooves, and the assembly block and assembly groove are inserted into each other. A locking groove is formed at one end of the assembly groove, and the locking block and locking groove are snapped together. An unlocking block is slidably connected inside the locking groove, with one end extending beyond the side of the fixing base. Limit blocks are symmetrically fixed to both ends of the unlocking block. Limit grooves are symmetrically formed at both ends of the locking groove, and the limit blocks and limit grooves are slidably connected. This design allows the bushing flanging device to adapt to bushings of different specifications, achieving multi-purpose functionality, improving the flexibility and utilization of the equipment, and facilitating the replacement of new components without replacing the entire device, thereby reducing maintenance costs and downtime.

[0009] As a preferred technical solution, a threaded post is fixedly connected to the bottom of the mounting base, and a threaded hole is opened at the upper end of the flanging punch. The threaded post and the threaded hole are connected by threads, which can complete the replacement of the flanging punch without complicated tools or skills, making it easier for operators to complete the replacement work, reducing the difficulty of operation and training costs.

[0010] As a preferred technical solution, a guide rod is fixedly connected to the outer wall of the mounting base, a movable seat is fixedly connected to the other end of the guide rod, and a guide block is symmetrically fixedly connected to the other end of the movable seat. A guide groove is symmetrically opened on one end of the fixed frame, and the guide block and the guide groove are slidably connected. The sliding of the guide block in the guide groove ensures the accurate path of the flanging punch during the descent process, reduces the offset and shaking of the punch during descent, and thus improves the positioning accuracy of the flanging operation.

[0011] As a preferred technical solution, the demolding assembly includes a receiving cavity, a second cylinder, a connector, and an ejector plate. The receiving cavity is located inside the worktable, and the second cylinder is installed at the bottom of the receiving cavity. The telescopic end of the second cylinder extends into the limiting cylinder and is fixedly connected to the connector. The ejector plate is symmetrically connected to the outer wall of the connector via a circular array. The upper end of the limiting cylinder has symmetrically formed sliding grooves via a circular array. The sliding grooves pass through the limiting cylinder and the mounting base. The sliding grooves and the ejector plate are slidably connected, which can ensure that the bushing can be quickly and smoothly removed after molding, thereby shortening the production cycle, improving the overall production efficiency, and reducing the damage and deformation of the bushing during the demolding process, ensuring that the dimensional accuracy and surface finish of the product meet the design requirements.

[0012] In summary, the present invention has the following main advantages:

[0013] First, in this utility model, the limiting cylinder together with the mounting base is placed on the upper end of the fixed base, so that the mounting block is inserted into the mounting groove. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block, so that the locking block drives the moving plate to press against the return spring. The locking block retracts into the cavity. When the locking block moves to the locking groove, the return spring resets, and the locking block pops out and engages with the locking groove, thus completing the installation of the limiting cylinder. This allows the bushing flange device to adapt to bushings of different specifications, realizes multiple uses of one machine, improves the flexibility and utilization rate of the equipment, and makes it easy to replace new parts without replacing the entire equipment, thereby reducing maintenance costs and downtime.

[0014] Secondly, in this utility model, the limiting cylinder together with the mounting base is placed on the upper end of the fixed base, so that the ejector plate slides into the sliding groove. At the same time, the connector is located inside the limiting cylinder. Then, after the bushing is flanged, the second cylinder is activated to control the connector to drive the ejector plate to rise. The ejector plate slides inside the sliding groove and ejects the bushing outside the limiting cylinder, completing the demolding of the bushing. This ensures that the bushing can be quickly and smoothly removed after molding, thereby shortening the production cycle, improving the overall production efficiency, and reducing the damage and deformation of the bushing during the demolding process, ensuring that the dimensional accuracy and surface finish of the product meet the design requirements.

[0021] Example

[0022] refer to Figures 1 to 5 The bushing flanging device described in this embodiment includes a worktable 1, a fixed frame 2 fixedly connected to one end of the worktable 1, a first cylinder 3 installed on the upper end of the fixed frame 2, a mounting base 4 fixedly connected to the telescopic end of the first cylinder 3, a flanging punch 5 movably connected to the bottom end of the mounting base 4, a fixed seat 12 fixedly connected to the upper end of the worktable 1, an assembly seat 13 movably connected to the upper end of the fixed seat 12, a limit cylinder 14 fixedly connected to the upper end of the assembly seat 13, a demolding component 15 installed inside the worktable 1, and assembly blocks 16 symmetrically fixedly connected to the bottom end of the assembly seat 13, with a fixing component 18 installed inside the assembly block 16.

[0023] The fixing assembly 18 includes a cavity 181, a return spring 182, a moving plate 183, and a locking block 184. The assembly block 16 has a cavity 181 inside. A return spring 182 is symmetrically fixedly connected to one end of the cavity 181, and a moving plate 183 is fixedly connected to the other end of the return spring 182. The moving plate 183 is slidably connected to the cavity 181. A locking block 184 is fixedly connected to the end of the moving plate 183 away from the return spring 182. The end of the locking block 184 away from the moving plate 183 extends out of the side of the assembly block 16. The bottom end of the locking block 184 is sloped. The fixing base 12 has symmetrically formed assembly grooves 17 on its upper end. The assembly block 16 is inserted into the assembly slot 17. A locking groove 19 is provided at one end of the assembly slot 17. The locking block 184 is snapped into the locking groove 19. The limiting cylinder 14 and the assembly base 13 are placed on the upper end of the fixed base 12, so that the assembly block 16 is inserted into the assembly slot 17. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 184, so that the locking block 184 drives the moving plate 183 to press against the return spring 182. The locking block 184 retracts into the cavity 181. When the locking block 184 moves to the locking groove 19, the return spring 182 returns to its original position, and the locking block 184 pops out and snaps into the locking groove 19, thus completing the installation of the limiting cylinder 14.

[0024] refer to Figure 5 An unlocking block 23 is slidably connected inside the locking groove 19. One end of the unlocking block 23 extends out of the side end of the fixing seat 12. Limiting blocks 20 are symmetrically fixedly connected at both ends of the unlocking block 23. Limiting grooves 21 are symmetrically opened at both ends inside the locking groove 19. The limiting blocks 20 and the limiting grooves 21 are slidably connected. Pushing the unlocking block 23 causes it to slide inside the locking groove 19. The unlocking block 23 drives the limiting blocks 20 to slide inside the limiting grooves 21. The unlocking block 23 pushes the locking block 184, causing the locking block 184 to drive the moving plate 183 to press against the return spring 182. The locking block 184 retracts into the cavity 181, and the locking block 184 and the locking groove 19 are no longer engaged. Pulling the limiting cylinder 14 upward causes the assembly block 16 and the assembly groove 17 to be no longer inserted, thus completing the disassembly of the limiting cylinder 14.

[0025] refer to Figure 3 The mounting base 4 has a threaded post 10 fixedly connected to its bottom end, and the flange punch 5 has a threaded hole 11 at its upper end. The threaded post 10 and the threaded hole 11 are threadedly connected. Rotating the flange punch 5 will disconnect the threaded post 10 from the threaded hole 11, thus completing the disassembly of the flange punch 5.

[0026] refer to Figures 1 to 2A guide rod 6 is fixedly connected to the outer wall of the mounting base 4. A movable seat 7 is fixedly connected to the other end of the guide rod 6. A guide block 9 is symmetrically fixedly connected to the other end of the movable seat 7. A guide groove 8 is symmetrically opened at one end of the fixing frame 2. The guide block 9 and the guide groove 8 are slidably connected. When the first cylinder 3 is started and the flanging punch 5 is controlled to descend, the mounting base 4 drives the guide rod 6 to descend. At the same time, the guide rod 6 drives the guide block 9 at one end of the movable seat 7 to slide inside the guide groove 8.

[0027] refer to Figure 4 The demolding assembly 15 includes a receiving cavity 151, a second cylinder 152, a connector 153, and an ejector plate 154. The receiving cavity 151 is located inside the worktable 1. The second cylinder 152 is installed at the bottom of the receiving cavity 151. The telescopic end of the second cylinder 152 extends into the limiting cylinder 14 and is fixedly connected to the connector 153. The outer wall of the connector 153 is symmetrically connected to the ejector plate 154 via a circular array. A sliding groove 22 is symmetrically formed at the upper end of the limiting cylinder 14 via a circular array, and the sliding groove 22 penetrates the limiting cylinder 151. 4. The mounting base 13 and the sliding groove 22 are slidably connected to the ejector plate 154. The limiting cylinder 14 together with the mounting base 13 is placed on the upper end of the fixed base 12, so that the ejector plate 154 slides into the sliding groove 22. At the same time, the connector 153 is located inside the limiting cylinder 14. Then, after the bushing is finished, the second cylinder 152 is started to control the connector 153 to drive the ejector plate 154 to rise. The ejector plate 154 slides inside the sliding groove 22 and ejects the bushing outside the limiting cylinder 14, thus completing the demolding of the bushing.

[0028] Operating principle and advantages: First, based on the required flanged bushing size, place the matching limiting sleeve 14 along with the mounting base 13 onto the upper end of the fixed base 12, allowing the mounting block 16 to be inserted into the mounting groove 17. During insertion, the pressing force applies pressure to the inclined surface of the locking block 184, causing the locking block 184 to drive the moving plate 183 to press against the return spring 182. The locking block 184 retracts into the cavity 181. When the locking block 184 moves to the locking groove 19, the return spring 182 returns to its original position. The locking block 184 pops out and engages with the locking groove 19, completing the installation of the limiting cylinder 14. The bushing is placed outside the limiting cylinder 14. The first cylinder 3 is started to control the flanging punch 5 to descend and flanging the bushing. After the bushing is flanging, the second cylinder 152 is started to control the connector 153 to drive the ejector plate 154 to rise. The ejector plate 154 slides inside the sliding groove 22 and ejects the bushing outside the limiting cylinder 14, completing the demolding of the bushing.

[0029] This invention enables the bushing flanging device to adapt to bushings of different specifications, achieving multiple uses in one machine, improving the flexibility and utilization of the equipment, and allowing for easy replacement of new parts without replacing the entire equipment, thereby reducing maintenance costs and downtime.
