Description

Technical Field

[0001] The utility model belongs to the technical field of bearing bush processing, and more specifically relates to a punching device used for bearing bush processing. Background Art

[0002] The bearing shell is the part where the sliding bearing and the shaft neck contact. It is in the shape of a semi-cylindrical shell. During the processing of the bearing shell, in order to facilitate the assembly of the bearing shell with the bearing and the shaft neck, positioning blocks are usually processed on the bearing shell to improve the stability of the bearing shell.

[0003] The existing stamping device for processing positioning blocks on the bearing has a stamping angle for stamping the bearing from the inside to the outside. However, since the bearing is made of a composite material, the internal material of the bearing after stamping at this angle will be damaged and cause material delamination, which reduces the fit between the inside of the bearing and the journal, resulting in poor heat dissipation at the delamination point of the bearing, affecting the use of the bearing. In severe cases, it may also cause damage to equipment such as engines equipped with the bearing.

[0004] Therefore, the processing of the bearing bush by the existing stamping device is not conducive to the use of the bearing bush and still needs further improvement. Utility Model Content

[0005] The utility model aims to solve the problem that the existing punching device easily causes delamination of the inner material of the bearing bush, resulting in poor heat dissipation effect at the delamination point of the bearing bush and affecting the use of the bearing bush.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a punching device for bearing processing, which is used to punch out a positioning block on the bearing;

[0007] The punching device comprises a material placing table, a material pressing mechanism and a material punching mechanism;

[0008] The material placement table is provided with a supporting block with an arc-shaped upper end, the bearing bush is sleeved on the supporting block, and a punching gap is provided on one side of the supporting block;

[0009] The material pressing mechanism is arranged at the upper end of the material placing table, and comprises a first driving assembly and a material pressing frame, and the material pressing frame can be pressed onto the bearing bush through the first driving assembly;

[0010] The punching mechanism is arranged at the lower end of the material placement table, and includes a second driving component and a punching rod with an upper end punch. The punch can punch one side of the bearing shell through the second driving component and the punching gap to form the positioning block.

[0011] Optionally, the stamping device also includes a feeding mechanism, which is arranged on one side of the loading platform and includes a third drive assembly, a pushing rack and a storage rack. The pushing rack is used to push the bearing on the storage rack onto the supporting block through the third drive assembly.

[0012] Optionally, the stamping device further includes a support frame, and the material placement table, the first drive assembly, the second drive assembly and the third drive assembly are all connected to the support frame.

[0013] Optionally, the first drive assembly, the second drive assembly and the third drive assembly all include a cylinder and a piston rod, and the piston rods on the three are respectively used to connect the press frame, the punch rod and the push frame.

[0014] Optionally, the support frame is provided with a first guide block and a second guide block for guiding the movement of the pressing frame and the pushing frame.

[0045] The material placing table 3 is provided with a supporting block 4 with an arc-shaped upper end, the bearing bush is sleeved on the supporting block 4, and a punching gap is provided on one side of the supporting block 4;

[0046] The material pressing mechanism is arranged at the upper end of the material placing table 3, and comprises a first driving assembly and a material pressing frame 5. The material pressing frame 5 can be pressed onto the bearing bush through the first driving assembly;

[0047] The punching mechanism is arranged at the lower end of the material placement table 3, which includes a second driving component and a punching rod 7 with an upper end punch 6. The punch 6 can punch one side of the bearing shell 1 through the second driving component and the punching gap to form a positioning block 2.

[0048] Specifically, the punch moves upward under the drive of the second driving assembly, the upper end of the punch passes through the punching gap, contacts the lower end of the bearing shell, and continuously squeezes the material at the lower end of the bearing shell, so that the material at the lower end of the bearing shell accumulates upward to form a positioning block.

[0049] In one embodiment, the stamping device also includes a feeding mechanism, which is arranged on one side of the loading platform 3, and includes a third driving component, a pushing rack 8 and a storage rack 9. The pushing rack 8 is used to push the bearing 1 on the storage rack 9 onto the supporting block 4 through the third driving component.

[0050] In one embodiment, a first groove 51 for pressing the bearing shell 1 is provided at the lower end of the pressing frame 5 .

[0051] In one embodiment, the storage rack 9 is mounted on the supporting block, and a second groove 91 for unloading and feeding the bearing shell 1 is provided at the lower end thereof.

[0052] Specifically, multiple bearings are stacked in a storage rack with their openings facing downward. The structure of the front end of the push rod is compatible with the structure of the bearing. After the third drive assembly drives the push rod, the push rod can push the bearing located at the bottom layer to the support rack at the pressing end to realize material feeding.

[0053] In a specific embodiment, the first groove 41 and the second groove 91 are both arc-shaped to fit with the exterior of the bearing shell.

[0054] In one embodiment, the stamping device further includes a support frame 10 , and the material placement table 3 , the first drive assembly, the second drive assembly and the third drive assembly are all connected to the support frame 10 .

[0057] When the punching device of the utility model is in use, the third driving component is first used to drive the pushing rack to move toward the storage rack, and the bearing shell in the storage rack is pushed onto the supporting rack through the second groove. The pressing rack is then driven downward by the first driving component to be pressed onto the bearing shell. Then, the punching rod is driven upward by the second driving component, and the upper end of the punch passes through the punching gap to contact the lower end of the bearing shell, thereby squeezing the lower end of the bearing shell to form a positioning block.

[0058] The utility model provides a stamping device for processing bearing shells. By arranging a supporting block with an arc-shaped upper end on a material placement table, the bearing shell can be clamped on the supporting block with its opening facing downward. By setting a pressing mechanism, the pressing frame can be used to press the bearing shell to prevent it from moving during stamping and affecting the stamping effect. Furthermore, by setting the punching mechanism, the punching rod can punch the lower end of the bearing shell through the punching gap to form a positioning block.

[0059] Furthermore, by providing the feeding mechanism, the storage rack and the pushing rack can facilitate the feeding of the bearing shells, thereby improving the efficiency of the bearing shell processing.

[0060] Compared with the existing stamping device, the stamping device of the utility model only stamps one end of the bearing shell and does not touch the inside of the bearing shell, thereby ensuring the integrity of the inside of the bearing shell, improving the fit between the bearing shell and the journal, and enabling the bearing shell to have a better heat dissipation effect when in use, which is beneficial to the use of the bearing shell.
