[0031] In order to solve the above technical problems, the present application provides a stamping mechanism. Specifically, Figures 1 to 6As shown, the stamping mechanism includes a clamping assembly 1 and a stamping assembly 2. The clamping assembly 1 includes a first clamping part 11, a second clamping part 12 and a support part 13. The first clamping part 11 and the second clamping part 12 are symmetrically arranged on both sides of the support part 13. The first clamping part 11 and the second clamping part 12 move relative to or away from each other, so that the clamping assembly 1 can clamp the first target part 7 when the first clamping part 11 and the second clamping part 12 move relative to each other, and release the second target part when the first clamping part 11 and the second clamping part 12 move away from each other. The support part 13 is used to support the first target part 7 or the second target part; the stamping assembly 2 is arranged above the clamping assembly 1, and the stamping assembly 2 is used to stamp the target part to be stamped. Among them, the second target part is obtained through the first target part 7, and specifically, the second target part is the first target part 7 after stamping.

[0032] It can be understood that the technical solution can realize the stamping of the first target part 7 after clamping and positioning by the stamping mechanism by controlling the relative movement between the symmetrically arranged first clamping member 11 and the second clamping member 12, reduce the shaking amplitude of the first target part 7 during the stamping process, improve the stamping accuracy, control the opposite movement between the first clamping member 11 and the second clamping member 12, and realize the release of the first target part 7, i.e., the second target part, after the stamping is completed by the stamping mechanism, provide sufficient demoulding space for the second target part, and provide sufficient installation space for the next target part, thereby increasing the demoulding speed of the second target part and the installation speed of the next target part, thereby improving the stamping efficiency.

[0033] In one example, the relative movement of the first clamp 11 and the second clamp 12 includes relative rotation, and the back-to-back movement of the first clamp 11 and the second clamp 12 includes back-to-back rotation. The stamping assembly 2 includes a stamping part 21 and a pressing part 22, and the stamping part 21 includes a mounting portion 211 and a stamping portion 212. The stamping part 21 is mounted in the pressing part 22 through the mounting portion 211, and the stamping portion 212 protrudes from the mounting plane at the mounting position of the pressing part 22. Among them, the shape of the stamping portion 212 needs to match the shape of the second target part obtained after the first target part 7 is stamped, so as to obtain a second target part with a target shape requirement, and therefore, the shape of the stamping portion 212 is determined based on the second target part. The pressing member 22 provides a pressing force for the clamping assembly 1. The pressing member 22 includes a first pressing portion 221 and a second pressing portion 222. The first pressing portion 221 provides a first pressing force for the first clamping member 11. The second pressing portion 222 provides a second pressing force for the second clamping member 12 when the first pressing portion 221 provides the first pressing force for the first clamping member 11. The second pressing force is opposite to the first pressing force. Figure 2 and Figure 3The clamping assembly 1 includes a first clamping base 14, a second clamping base 15, a first rotating shaft 16 and a second rotating shaft 17. The first clamping base 14 and the second clamping base 15 are symmetrically arranged on both sides of the support member 13. The first clamping member 11 is arranged in the first clamping base 14. The first rotating shaft 16 passes through the first clamping base 14 and the first clamping member 11. The first clamping member 11 rotates around the first rotating shaft 16. The second clamping member 12 is arranged in the second clamping base 15. The second rotating shaft 17 passes through the second clamping base 15 and the second clamping member 12. The second clamping member 12 rotates around the second rotating shaft 17. When the pressing member 22 acts on the clamping assembly 1, the first clamping member 11 rotates in the first rotation direction around the first rotating shaft 16 under the action of the first pressing force of the first pressing portion 221, and the second clamping member 12 rotates in the second rotation direction around the second rotating shaft 17 under the action of the second pressing force of the second pressing portion 222. The first rotation direction and the second rotation direction are opposite. At this time, the first clamping member 11 and the second clamping member 12 realize relative rotation to clamp the first target member 7. Further, after the clamping assembly 1 completes the clamping of the first target member 7, the stamping assembly 2 stamps the first target member 7 to obtain the second target member, and the pressing assembly is reset at this time. In another preferred embodiment of this example, the stamping assembly 2 is integrally formed.

[0034] In this example, the clamping stability of the first target part 7 is improved by balancing the first abutting force and the second abutting force.

[0035] In another example, see Figure 4 and Figure 5 The clamping assembly 1 includes a first supporting spring 18 and a second supporting spring 19. The first supporting spring 18 is used to support the first clamping member 11, and the second supporting spring 19 is used to support the second clamping member 12. The first clamping member 11 rotates around the supporting point of the first supporting spring 18 under the action of the first pressing force, and the second clamping member 12 rotates around the supporting point of the second supporting spring 19 under the action of the second pressing force. It can be understood that the supporting point mentioned in this example can refer to the point where the spring bends. In this example, the elastic properties of the spring can be used to adjust the relative positions of the first clamping member 11 and the second clamping member 12 based on the bending of the spring to achieve the clamping of the first target member 7. The structure is simple and cost-saving.

[0036] In another example, the relative movement of the first clamping member 11 and the second clamping member 12 includes relative movement, and the back-to-back movement of the first clamping member 11 and the second clamping member 12 includes back-to-back movement. In this example, the first pressing portion 221 provides a first thrust or a first pulling force to the first clamping member 11, and the second pressing portion 222 provides a second thrust to the second clamping member 12 when the first pressing portion 221 provides a first thrust to the first clamping member 11, and the second pressing portion 222 provides a second pulling force to the second clamping member 12 when the first pressing portion 221 provides a first pulling force to the first clamping member 11, so that the second clamping member 12 provides a second thrust or a second pulling force, so that the clamping assembly 1 clamps the first target member 7 under the action of the first thrust and the second thrust, and the clamping assembly 1 releases the second target member under the action of the first pulling force and the second pulling force.

[0037] In one example, the stamping assembly 2 can be formed in one piece.

[0038] Furthermore, the stamping mechanism further comprises a mandrel 3, and the first target part 7 or the second target part is sleeved on the mandrel 3. By arranging the mandrel 3 to support the first target part 7, the stamping pressure can be buffered when the first target part 7 is stamped, thereby reducing the stamping deformation of the first target part 7.

[0039] For further information, see Figure 6 The punching mechanism further includes an ejection assembly, which includes an ejector pin 4, which is used to provide an ejection force when the second target part is demolded. By providing the ejector pin 4, the demolding of the second target part obtained after punching can be assisted, thereby improving the demolding efficiency.

[0040] Furthermore, the stamping mechanism further includes a limit assembly and a motion guide column, one end of the motion guide column is connected to the stamping assembly 2, and the other end of the motion guide column passes through the limit assembly. The motion guide column is used to guide the stamping direction of the stamping assembly 2, reduce the deviation of the stamping angle of the stamping assembly 2, and improve the stamping accuracy. The limit assembly is used to limit the stamping distance of the stamping assembly 2, reduce the probability of over-stamping, and improve the stamping accuracy.

[0041] For further information, see Figure 1 The punching mechanism further includes a clamping auxiliary component 5, which is arranged on the other side of the clamping component 1 relative to the core rod 3, and is used to assist in clamping the first target part 7 or the second target part. Specifically, by setting the auxiliary clamping component 1, the first target part 7 can be auxiliary clamped to reduce the downward slope of the end away from the clamping component 1 due to the long spacing during the feeding conveying mechanism to transport the first target part 7, thereby improving the feeding accuracy.

[0042] Furthermore, the stamping mechanism further comprises a limiter 6, and the clamping auxiliary assembly 5 is arranged between the limiter assembly and the clamping assembly 1. Specifically, the limiter assembly is used to limit the reverse sliding of the first target member 7 relative to the transport direction, thereby improving the stamping accuracy.

[0043] As an exemplary illustration, the stamping mechanism of the present application can be used to stamp the chair leg tubes of office chairs to meet the needs of chair legs of different shapes.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
