[0003] Existing punch presses for buffer sleeve processing lack components that allow for flexible and rapid die replacement to meet processing needs, and lack auxiliary unloading components after stamping, which affects the overall processing efficiency of buffer sleeves. Therefore, this paper proposes a punch press for buffer sleeve processing to provide buffer sleeve processing personnel with a press press mechanism that allows for rapid die replacement. This mechanism is simple to use, facilitates die replacement, has good applicability and high practicality, and can improve processing efficiency. Summary of the Invention

It is simple to use, the die base is easy to replace, it has good applicability and high practicality, and can improve processing efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is a punch press for processing buffer sleeves, including a worktable, a cylinder, a die, and a quick-change die holder. A machine frame is fixedly installed on the top of the worktable, the cylinder is fixed on the machine frame, the die is installed on the output end of the cylinder by bolts, L-shaped retaining strips are fixed at both ends of the top of the worktable, and the quick-change die holder is arranged between the L-shaped retaining strips and is located below the die.

[0006] By adopting the above technical solution, a press-fitting mechanism with a quick-change die base is provided for buffer sleeve processing personnel through the components consisting of a worktable, cylinder, die, and quick-change die base. It is simple to use, the die base is easy to replace, and it can be flexibly replaced for different buffer sleeve bushings, thus improving the scope of application, with good applicability and high practicality.

[0007] Specifically, the quick-change mold base includes a base plate, a mold sleeve, a top outlet, and an upper pin hole, with the base plate inserted between the L-shaped retaining strips.

[0008] By adopting the above technical solution, the quick-change mold base is guided and secured by an L-shaped locking strip.

[0009] Specifically, the mold sleeve is fixed to the base plate, and the top outlet is opened through the bottom of the mold sleeve.

[0010] Specifically, the worktable has a lower pin hole corresponding to the upper pin hole, and the upper pin hole and the lower pin hole are fixed together by a spring pin.

[0011] By adopting the above technical solution, the quick-change mold base auxiliary pin is fixed to the worktable by a spring pin.

[0012] Specifically, an electric cylinder is fixedly installed at the bottom of the workbench, and a top block is fixed to the output end of the electric cylinder.

[0013] Specifically, a storage slot corresponding to the top block is provided on the worktable between the L-shaped card strips, and the storage slot is perpendicular to the top outlet.

[0014] By adopting the above technical solution, the top block can be used in conjunction with the electric cylinder to eject the press-fitted buffer sleeve after the stamping operation, assisting the worker in unloading the material and further improving processing efficiency.

[0015] The beneficial effects of this utility model are as follows: The assembly, consisting of a worktable, cylinder, die, and quick-change die holder, provides a press-fitting mechanism for buffer sleeve processing personnel with a quick-change die holder. It is simple to use, the die holder is easy to replace, and it can be flexibly changed for different buffer sleeve bushings, increasing its application range, applicability, and practicality. Furthermore, it is equipped with a top block structure that can eject the press-fitted buffer sleeve after the stamping operation, assisting workers in unloading and further improving processing efficiency. This solves the problems of existing buffer sleeve bushing press-fitting punches being unable to flexibly and quickly change the die holder according to processing needs, and the lack of auxiliary unloading components after stamping, which affects the overall buffer sleeve processing efficiency.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] To increase the processing range, such as Figure 1-5 As shown, the punch press for processing buffer sleeves according to this utility model includes a worktable 1, a cylinder 3, a die 4, and a quick-change die holder 5. A machine frame 2 is fixedly installed on the top of the worktable 1, the cylinder 3 is fixed on the machine frame 2, the die 4 is installed on the output end of the cylinder 3 by bolts, L-shaped retaining strips 6 are fixed at both ends of the top of the worktable 1, and the quick-change die holder 5 is disposed between the L-shaped retaining strips 6 and is located below the die 4.

[0025] In use, the workbench 1, cylinder 3, pressure mold 4 and quick-change mold base 5 provide the buffer sleeve processing personnel with a press-fitting mechanism with quick mold base replacement. It is simple to use, the mold base is easy to replace, and it can be flexibly replaced for different buffer sleeve bushings, thus improving the scope of use.

[0026] For example, such as Figure 4 As shown, the present invention also includes a quick-change mold base 5 comprising a base plate 501, a mold sleeve 502, a top outlet 503 and an upper pin hole 504, wherein the base plate 501 is inserted between the L-shaped clips 6.

[0027] The mold sleeve 502 is fixed on the base plate 501, and the top outlet 503 is opened through the bottom of the mold sleeve 502.

[0028] When using, select the required mold sleeve 502 specification quick change mold base part 5 and assemble it on the L-shaped retaining strip 6, and use the L-shaped retaining strip 6 to guide and lock the quick change mold base part 5 in the assembly direction.

[0029] For example, such as Figure 2 , 3 As shown in Figure 4, the present invention also includes a lower pin hole 7 on the workbench 1 that corresponds to the upper pin hole 504, and the upper pin hole 504 and the lower pin hole 7 are fixed together by a spring pin 8.

[0030] During use, the upper pin hole 504 and the lower pin hole 7 are fixed by the spring pin 8, so that the use position of the quick change mold base part 5 is fixed.

[0031] For example, such as Figure 2 , 5 As shown, the present invention also includes an electric cylinder 10 fixedly installed at the bottom of the workbench 1, and a top block 11 fixed at the output end of the electric cylinder 10.
