Description

Technical Field

[0001] This utility model relates to the field of bushing production technology, and in particular to a flanging device for automotive bushings. Background Technology

[0002] A bushing is a component used on the outside of mechanical parts to achieve functions such as sealing and wear protection; it refers to a ring that acts as a gasket. In valve applications, bushings are placed inside the valve cover and are generally made of corrosion-resistant materials such as polytetrafluoroethylene (PTFE) or graphite for sealing. Flanging refers to a forming method where a die is used to create a straight wall or flange at a certain angle along a closed or open curved edge on the flat or curved portion of a blank. Flanging is a type of stamping process. There are many types of flanging, and the classification methods vary. Based on the nature of deformation, they can be divided into elongation flanging and compression flanging.

[0003] A document with publication number CN221018163U discloses a flanging device for automotive bushings, relating to the field of automotive bushing flanging technology. The device includes a worktable and a flanging die. The worktable has a top frame on its top surface, with hydraulic rods fixed to both sides of the top surface of the top frame. A mounting base is fixed to the bottom end of each hydraulic rod. Insert blocks are provided on both sides of the top surface of the flanging die, and these insert blocks are internally inserted into the mounting base. Bolts are installed in the shaft holes on the front side of the mounting base. A base frame is provided on both sides of the bottom surface of the worktable. An adjustment unit is provided on the top surface of the worktable. This automotive bushing flanging device allows for quick disassembly and replacement of the bushing post and flanging die using bolts and screws, depending on the specifications of the automotive bushing. This facilitates flanging processing of automotive bushings of different specifications. Simultaneously, an air pump can be activated to clean material residue from the surface of the automotive bushing, preventing the adhering residue from affecting the subsequent flanging effect.

[0004] However, when using this flanging equipment, the flanging operation can only begin after the currently flanged automotive bushing has been removed and a new bushing has been installed. This results in a long idle waiting time for the equipment and low production efficiency.

[0005] Therefore, it is necessary to provide a flanging device for automotive bushings to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0028] Example 1:

[0029] like Figure 1-5As shown, the flanging device for automotive bushings provided by this utility model includes: a housing 1, on which a flanging mechanism is provided, the flanging mechanism including four guide posts 2 and a pressure plate 3, the two ends of the guide posts 2 being connected to the housing 1, the guide posts 2 penetrating the pressure plate 3, allowing the pressure plate 3 to move laterally along the guide posts 2, and four hydraulic cylinders 9 being installed on both sides of the pressure plate 3, two on each side of the pressure plate 3, one end of each hydraulic cylinder 9 being connected to the housing 1, and controlled by hydraulic pressure. Cylinder 9 drives the pressure plate 3 to move laterally. A flanging mold 4 is installed on each of the left and right sides of the pressure plate 3. A bushing fixing assembly is installed on the side opposite to the flanging mold 4. The bushing fixing assembly includes a track frame 5 installed inside the housing 1. The track frame 5 is fixedly connected to the inner wall of the housing 1 via four support rods 6. A support plate 7 is longitudinally slidably installed on the track frame 5. A bushing column 8 is installed on the side of the support plate 7 opposite to the flanging mold 4. An electric push rod 10 is installed on the (tail) side of the support plate 7. The push rod 10 is fixedly connected to the housing 1. In use, the electric push rod 10 on the left is activated, which pushes the support plate 7 to move longitudinally. This causes the bushing column 8 to extend forward to the vicinity of the operator. The operator places the car bushing to be flanged onto the bushing column 8. Then, the electric push rod 10 is activated again, causing the support plate 7 to return to its initial position, i.e., the bushing column 8 is aligned with the flanging mold 4 on that side. The hydraulic cylinder 9 is activated, pushing the pressure plate 3 to move to the left, causing the flanging mold 4 on the left to press onto the car bushing and flanging it. Then, the pressure plate 3 retracts to the middle, causing the flanging mold 4 to leave the flanged car bushing. During this period, the car bushing to be flanged can be installed on the bushing column 8 on the right side of the pressure plate 3. Therefore, after the pressure plate 3 returns to the middle, it can immediately continue to move to the right to flanging the car bushing on the right side, thus achieving continuous flanging operation. The left and right sides are alternately used for flanging operations, which greatly reduces the idle waiting time of the equipment and can greatly improve the operating efficiency of the equipment.

[0030] By setting up the housing 1 and the flanging mechanism, and setting the flanging mold 4 and bushing column 8 on both the left and right sides of the pressure plate 3, the pressure plate 3 can continuously perform flanging operations when it moves back and forth, which greatly reduces the idle waiting time of the equipment and helps to improve production efficiency.

[0031] Example 2:

[0032] like Figure 4 As shown, four sleeves 11 are installed on the pressure plate 3. Wear-resistant sleeves are installed inside the sleeves 11. The wear-resistant sleeves are provided with lubrication holes or lubrication grooves. The guide post 2 passes through the sleeves 11. By injecting grease into the wear-resistant sleeves, the friction between the sleeves 11 and the guide post 2 is reduced, thereby reducing wear and noise.

[0033] By installing four sleeves 11 on the pressure plate 3, the connection between the pressure plate 3 and the guide column 2 can be facilitated.

[0034] Example 3:

[0035] like Figure 1 As shown, a worktable 12 is installed inside the housing 1. The height of the worktable 12 is lower than the height of the lowest point of the bushing after it is installed on the bushing column 8 (the height difference is 10-15cm). Therefore, after the bushing column 8 moves forward longitudinally, the bushing will not touch the worktable 12 and will maintain a certain distance from the worktable, facilitating the loading and unloading of the bushing. A chip removal slot 13 is provided on the worktable 12, and two fans 14 are installed above the chip removal slot 13. The fans 14 are aligned with the loading and unloading stop points of the bushing. During operation, the support plate 7 moves forward longitudinally. The bushing with the flange already turned on on the bushing column 8 is sent to the area below the blower 14. The blower 14 blows air onto the bushing to cool it down and prevent it from being burned due to excessive heat generated during the flange turning. The bushing is then removed and a new bushing to be flanged is installed. The blower 14 blows off any material residue or other debris adhering to the surface of the bushing. The material residue falls from the chip removal seam 13 to the area below the workbench 12, preventing the material residue on the surface of the bushing from being compressed during the flange turning process, which would cause pits on the surface of the bushing. This helps to improve the quality of the bushing and, in turn, improves the quality of the product.

[0036] By setting up a workbench 12 and opening a chip removal slit 13 on the workbench, and using a fan 14 to blow air onto the bushing, it is beneficial to cool down the bushing and improve its quality.

[0037] Example 4:

[0038] like Figure 1 As shown, a waste box 16 is installed below the workbench 12. The waste box 16 is located below the chip removal seam 13. When in use, the debris falling from the chip removal seam 13 falls into the waste box 16. The waste box 16 collects the falling debris in a unified manner, which is convenient for subsequent processing.

[0039] By installing a waste collection box 16 under the workbench 12, fallen debris can be easily collected for subsequent unified processing.

[0040] Example 5:

[0041] like Figure 1 As shown, a controller 15 is installed on one side of the housing 1. The controller 15 is connected to the hydraulic cylinder 9 and the electric push rod 10. Through the corresponding programming program, the controller 15 controls the start and stop, stroke and other parameters of the hydraulic cylinder 9 and the electric push rod 10. The operator can input the corresponding parameters through the control panel on the controller 15 so as to better suit the current bushing production and obtain better product quality and efficiency.

[0042] By installing a controller 15 on one side of the housing 1, the production parameters of the equipment can be easily adjusted.

[0043] Example 6:

[0044] like Figure 1-2 As shown, control buttons 17 are installed on both the left and right sides of the workbench 1. The control buttons 17 are connected to the controller 15. The control buttons 17 include a start button, a stop button, and an emergency stop button. Operators can use either side of the control button 17 to press the control button 17 when the left hand is convenient and the right hand is convenient when the right hand is convenient. Both hands can conveniently control the current equipment.

[0045] By installing control buttons 17 on both the left and right sides of the workbench 1, the production of the equipment can be easily controlled.

[0046] Working principle: In use, the electric push rod 10 on the left is activated, which pushes the support plate 7 to move longitudinally. This causes the bushing column 8 to extend forward to the vicinity of the operator. The operator places the car bushing to be flanged onto the bushing column 8. Then, the electric push rod 10 is activated again, causing the support plate 7 to return to its initial position, i.e., the bushing column 8 is aligned with the flanging mold 4 on that side. The hydraulic cylinder 9 is activated, pushing the pressure plate 3 to move to the left, causing the flanging mold 4 on the left side to press onto the car bushing, flanging the car bushing. Then, the pressure plate 3 retracts to the middle, causing the flanging mold 4 to leave the flanged car bushing. During this period, the car bushing to be flanged can be installed on the bushing column 8 on the right side of the pressure plate 3. Therefore, after the pressure plate 3 returns to the middle, it can immediately continue to move to the right to flanging the car bushing on the right side, thus achieving continuous flanging operation. The flanging operation is carried out alternately on the left and right sides, which greatly reduces the idle waiting time of the equipment and can greatly improve the working efficiency of the equipment.
