Description

Technical Field

[0001] The utility model relates to the structure of a bearing seat flanging die, and belongs to the technical field of bearing seat flanging dies. Background Art

[0002] The bearing seat flanging die is a common die in stamping processing. It is mainly used to perform flanging processing on the bearing seat. The flanging process is a link in the stamping process. It can allow the plate or other materials to be folded along a certain curve to form a vertical edge. Such a vertical edge helps to improve the connection strength of the parts and the aesthetic appearance.

[0003] A Chinese patent application (publication number: CN 204018546 U) discloses an S-shaped wheel flange bearing seat flanging die, comprising a die handle, an upper die seat, a lower die seat, and a ball guide connecting the upper and lower die seats. A punch fixing plate, a punch, and a positioning punch are sequentially connected from the upper die seat toward the lower die seat, with a stripper plate provided on the side of the positioning punch. The lower die seat is connected to a contour push rod and a die push plate, the side of which is connected to a die fixing plate, which is provided with a die. To prevent material from slipping outward during the flanging process, the utility model adopts a positive structure, combined with a press air cushion, to facilitate adjustment of the preload pressure, ensuring concentricity of the inner and outer diameters of the product after flanging.

[0004] A flanging die usually includes an upper die and a lower die, which work together to complete the flanging of parts. However, the upper die will gradually wear out the cutting edge material due to long-term stamping, and the cutting edge will become blunt, affecting the precision and quality of the stamped parts. In addition, the lower die will wear out during the stamping process, which will increase the friction between the plate and the die, further accelerating the wear rate. Wear will cause the gap between the lower die and the upper die to change, affecting the size and shape of the stamped parts. The upper die of the above patent is not easy to disassemble and replace, and the inconvenient replacement of the upper die will lead to interruption of the production process, prolong the die replacement time, and thus reduce production efficiency.

[0005] Therefore, a structure of a bearing seat flanging die is proposed. Utility Model Content

The other end of the connecting rod 209 is movably connected to the outer side of the fixed block 210 through a bearing.

[0030] By setting up the disassembly and assembly mechanism 2, the upper mold 1 can be quickly disassembled and assembled, reducing the time for disassembly of the upper mold 1, achieving the effect of facilitating disassembly and assembly, making it convenient for the staff to replace the new upper mold 1 according to stamping needs, reducing the staff's workload, and making it convenient for the staff to inspect and perform daily maintenance on the upper mold 1, bringing great convenience to the staff.

[0031] Example 2

[0032] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5As shown, in one embodiment, the middle end of the top of the support seat 5 is fixedly connected to the cylinder 6, the connecting seat 201 is fixedly connected to the output end of the cylinder 6, and slots 213 are provided on both sides of the connecting seat 201. The inner side of the limit block 212 passes through the inner cavity of the slot 213 and is inserted into the inner cavity of the limit slot 203. The bottom of the lower mold 4 is connected to the top of the support plate 3 through threaded connection with positioning bolts 7. The lower mold 4 is threadedly connected to the top of the support plate 3 through the positioning bolts 7. The outer side of the sliding sleeve 207 is fixedly connected to the pull rod 8. A pull groove 9 is provided on the outer side of the device box 205.

[0034] When the utility model is working: the bearing seat is placed on the top of the lower mold 4, and the connecting seat 201 is driven to descend by the output end of the cylinder 6, thereby driving the upper mold 1 to descend for stamping work, and the flanging work is completed by the cooperation of the upper mold 1 and the lower mold 4. When it is necessary to disassemble the upper mold 1, the pull rod 8 is pulled outward, so that the pull rod 8 drives the sliding sleeve 207 to slide outward on the surface of the sliding rod 206, so that the sliding sleeve 207 squeezes the return spring 208, causing the return spring 208 to deform and drive 219 to move outward. The cooperation between 219 and the fixed block 210 drives the fixed plate 211 to move outward, so that the fixed plate 211 drives the limiting block 212 to disengage from the inner cavity of the limiting groove 203, and then the upper mold 1 is pulled downward, so that the upper mold 1 drives the clamping block 202 to disengage from the inner cavity of the clamping groove 204, and the disassembly is completed;

[0035] When the upper mold 1 needs to be installed, the pull rod 8 is pulled outward, so that the pull rod 8 drives the sliding sleeve 207 to slide outward on the surface of the sliding rod 206, so that the sliding sleeve 207 squeezes the return spring 208, causing the return spring 208 to deform and drive 219 to move outward. Through the cooperation of 219 and the fixed block 210, the fixed plate 211 is driven to move outward, so that the fixed plate 211 drives the limit block 212 to move outward, and the upper mold 1 is clamped to the inner cavity of the slot 204 through the clamping block 202. The pull rod 8 is released, and the return spring 208 is deformed again due to the loss of force, so that the fixed plate 211 moves inward and drives the limit block 212 to be inserted into the inner cavity of the limit slot 203 through the inner cavity of the notch 213, completing the fixed installation of the upper mold 1, reducing the time for disassembly of the upper mold 1, and achieving the effect of easy disassembly and assembly.
