Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal riveting, and relates to a combined precision sheet metal stamping riveting die. Background Art

[0002] The main purpose of stamping and riveting sheet metal parts is to separate the sheet metal parts from the sheet material to maintain the quality requirements of the separated section when processing the sheet metal shell. In addition, the stamping process can achieve efficient and large-scale production by stamping hot-rolled or cold-rolled steel plates into the shape of the parts required for manufacturing. Moreover, compared with traditional cutting or welding processes, stamping and riveting has higher precision and stability, and can better guarantee the size and shape accuracy of the parts. However, during the stamping and riveting process of sheet metal parts, if the rivet joint cannot be slowly released, it may cause a series of problems.

[0003] First, the release problem of the rivet joint may cause damage to the surface of the sheet metal. During the stamping riveting process, if the rivet joint cannot be released smoothly, it may cause cracks, indentations or deformation on the surface of the sheet metal. These problems not only affect the quality of the sheet metal, but may also cause greater problems during subsequent processing or use.

[0004] Secondly, rivet joints that cannot be released may also affect the strength and stability of sheet metal parts. Since rivet joints play a key role in the connection of sheet metal parts, if they cannot be released smoothly, it may lead to a loose connection or even failure in some cases. This may have a negative impact on the overall strength and stability of sheet metal parts, reducing the quality and reliability of the product.

[0005] Furthermore, the inability to release the rivet head slowly may affect production efficiency. During the stamping riveting process, if the rivet head cannot be released smoothly, manual intervention may be required, which not only increases the operation time but also may lead to a decrease in production efficiency. In addition, if the release problem occurs frequently, the equipment may need to be repaired or replaced, which will further increase production costs.

[0006] Finally, the inability to release the rivet head slowly may also pose a threat to the safety of the operator. During the punch riveting process, if the rivet head cannot be released smoothly, it may cause equipment failure or operating error, which in turn poses a threat to the safety of the operator. Therefore, ensuring the safety of the operator is also one of the important factors that need to be considered.

[0007] In summary, the inability to slowly release the rivet joints during the stamping and riveting process of sheet metal parts will cause many problems, including damaging the surface of the sheet metal parts, affecting the strength and stability, affecting the production efficiency, and posing a safety threat to the operators. Therefore, there is an urgent need for a combined precision sheet metal stamping and riveting die to solve the above problems. Utility Model Content

The pressure of the top seat 100 can be relieved by using the buffer columns 150.

[0030] The positioning column 110 is connected to an external hydraulic mechanism device. The external hydraulic mechanism is a hydraulic punching machine. The punching head of the external hydraulic mechanism is fixed to the fixed pressure head 120 by bolt connection. The external hydraulic mechanism can provide punching power to the fixed pressure head 120.

[0031] The constant pressure head 120 passes through the middle position of the fixing seat 130 and is connected and fixed to the middle position of the connecting seat 140. The connecting seat 140 and the upper ends of the two groups of pressure-bearing heads 240 are mutually embedded and connected.

[0036] See also Figure 1-Figure 3 As the second embodiment of the present utility model: based on the description in the above embodiment, further, when the riveting mechanism performs stamping and riveting operations on the sheet metal parts, since the connecting seat 140 and the upper ends of the two groups of pressure-bearing heads 240 are mutually embedded and connected, the connecting seat 140 squeezes the two groups of pressure-bearing heads 240 after being compressed, and the pressure-bearing heads 240 are forced to squeeze the sleeve 210 to move downward, and squeeze the spring damping column 220 to compress, and at the same time, the rivet head 230 is subjected to the pressure of the spring damping column 220 to perform stamping and riveting on the sheet metal parts downward, after the riveting operation is completed, the spring damping column 220 releases the reverse force to push the rivet head 230 out, and prepares for the next stamping and riveting operation, and at the same time, since the insert head and the limiting groove 250 are mutually embedded, the compression stroke length of the spring damping column 220 is consistent with the cross-sectional length of the limiting groove 250, and the limiting groove 250 and the insert head can limit the pressure of the spring damping column 220 and release the pressure, thereby ensuring the stable use of the riveting mechanism.
