Description

Technical Field

[0001] This invention relates to the field of mold technology, and specifically to a mold with an anti-flanging and shaping composite structure and its method of use. Background Technology

[0002] In recent years, through years of technological updates and continuous accumulation, various mold companies have established a complete mold CAD / CAM / CAPP development system. On this basis, they have developed and applied "refined 3D solid design" technology, and new structures and functions have been successfully applied to the structural design and manufacturing of molds for various car body panels. These technologies can effectively ensure the stamping quality of parts and reduce the material cost of parts.

[0003] The stamping of parts typically involves processes such as drawing, trimming and punching, and flanging and shaping, requiring 3 to 5 processes and corresponding dies. Therefore, the most direct way to reduce stamping costs is to reduce the number of processes and the number of dies developed. This requires integrating the processes performed by different dies into a single die, but this method increases the complexity of the die's processes and its structure. Die structures often integrate different processes such as trimming and shaping into a single process, but processes with different flanging and shaping directions need to be implemented in different processes. Existing conventional structures cannot handle this if processes with different flanging and shaping directions are placed in the same process. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by providing a mold with an anisotropic flanging and shaping composite structure and its usage method. This integrates the flanging and shaping process, which previously required two separate steps, into a single step, thereby reducing the number of mold steps and lowering mold development costs.

[0005] To achieve the above objectives, the present invention relates to a mold with an anisotropic flanging and shaping composite structure, comprising an upper mold and a lower mold. The lower mold has a fixed punch for placing parts and a horizontally movable punch. When the movable punch is moved to its rightmost position, its end extends beyond the rightmost side of the fixed punch. The upper mold contains a pressure plate for pressing the parts. A movable flanging device is mounted in the upper mold via a slide rail. The flanging device has a fixed first wedge flanging slider. The lower mold has a first driving block that contacts the bottom of the flanging device. When the upper die is pressed down, the flanging device drives the first wedge flanging slider to move towards the fixed punch under the pressure of the first driving block. At least one guide rod is fixedly provided below the first wedge flanging slider, and the guide rod is movably connected to the second wedge flanging slider. The lower die is provided with a second driving block that contacts the bottom of the second wedge flanging slider. When the flanging device moves towards the fixed punch, after the bottom of the second wedge flanging slider contacts the second driving block, the second driving block presses the second wedge flanging slider to move upward.

[0006] Preferably, the upper mold is provided with a movable punch driving module, the movable punch is provided with a vertical driven module, and the contact surface between the movable punch driving module and the driven module is wedge-shaped.

[0007] Preferably, the upper mold has a vertically downward-facing guide end, and the lower mold has a guide groove that matches the guide end.

[0008] Preferably, a clamping block is provided below the movable punch.

[0009] A method for using a mold with an anisotropic flanging and shaping composite structure includes the following steps:

[0010] A) The part is placed on the fixed punch, the upper die moves downward, the movable punch begins to move horizontally, and the first wedge flange slider contacts the first drive block and begins to move horizontally.

[0011] B) The upper mold continues to descend, the movable punch moves into position, the pressure plate begins to press the material, and the first wedge-shaped flanging slider begins to flanging.

[0012] C) The upper mold continues to descend, the first wedge flanging slider continues to flanging, and at this time the second wedge flanging slider begins to move along the guide rod under the drive of the second drive block, and presses the shape protrusion laterally onto the part flanging edge;

[0013] D) The upper die continues to descend to the bottom, the first wedge flanging slider completes the flanging, and the second wedge flanging slider completes the lateral stamping convex shape.

[0014] E) After the part is stamped, the upper die moves upward, and at this time the movable punch retracts into place. The movable punch disengages from the part, and the punch-shaped part can be grasped and removed by the robot.

[0015] Preferably, the upper mold is provided with a movable punch driving module, and the movable punch is provided with a vertical driven module. The contact surface between the movable punch driving module and the driven module is wedge-shaped. In step A), when the upper mold moves downward, the movable punch is driven to move by the movable punch driving module.

[0016] Preferably, the upper mold has a vertically downward guide end, and the lower mold has a guide groove that matches the guide end. When the upper mold moves downward, the guide end and the guide groove ensure the accuracy of the movement direction of the upper mold.

[0017] Preferably, a clamping block is provided below the movable punch, and in step B), the first wedge-shaped flanging slider cooperates with the clamping block to flanging the part.

[0018] Compared with the prior art, the present invention has the following advantages: by adding a set of wedge structures to the traditional wedge forming structure, and through the design of guiding, limiting, pressure matching and driving structures, the process contents of two different flanging forming directions are integrated into one process. Furthermore, the design of the movable punch cleverly solves the problem of conveying and picking up parts, reduces the number of mold processes and lowers the mold development cost.
