[0030] The utility model proposes an upper and lower flanging die for a shock absorber limiting cover plate, which is used in a flanging forming process. The structure of the flanging forming punch, the center flanging forming groove, the arc surface flanging forming groove, and the flanging placing punch platform in the utility model is particularly suitable for the processing of a shock absorber limiting cover plate that requires flanging processing in the center and on one side and has different flanging directions.

[0031] In general, the upper and lower flanging molds of the shock absorber limit cover plate proposed in the utility model mainly include an upper mold plate 1, a movable mold positioning plate 13, a movable mold plate 2, a fixed mold plate 3, and a fixed mold positioning plate 43. Figure 1 , which shows the arrangement relationship of the upper mold plate 1, the movable mold positioning plate 13, the movable mold plate 2, the fixed mold plate 3, and the fixed mold positioning plate 43.

[0032] When the upper and lower flanging mold of the shock absorber limit cover plate proposed in the utility model is used, the mold is installed as a whole on the punching machine, the positioning hole on one side of the material plate is inserted into the positioning hole limit guide boss 35, and the center of the material plate is placed on the flanging placement punch 33. Figure 4 During the stamping as shown, the movable platen 2 is driven by the punching machine to press downward into the fixed platen 3 to complete the mold closing. During the pressing process of the movable platen 2, the movable platen 2 drives the material plate to press downward so that the position of the material plate changes from the top of the flanging placement punch 33 to the top of the fixed platen 3, completing the flanging of the center joint of the material plate toward the top. At the same time, the top of the limiting boss 34 and the truncated cone-shaped top of the positioning hole limiting guide boss 35 play a guiding and limiting role. The rear flanging forming punch 21 presses one side of the material plate into the arc surface flanging forming groove 31 to complete the arc-shaped downward flanging of one side of the material plate. The final product is as shown in FIG. Figure 5 As shown, after the mold closing process is completed, the punching machine is driven to separate the movable mold plate 2 and the fixed mold plate 3 to directly remove the formed shock absorber limit cover plate material and install a new material plate on the fixed mold plate 3 for batch processing.

[0033] A movable mold positioning plate 13 is provided in the middle of the bottom of the upper mold plate 1 through a screw connection, and an upper mold stop column 11 is provided on the left and right sides of the movable mold positioning plate 13 in the middle of the bottom end of the upper mold plate 1, and a guide sleeve 12 is provided on the left and right sides of the bottom end of the upper mold plate 1 close to the diagonal direction. The guide sleeve 12 and the guide column 42 on the fixed mold plate 3 play a role in the initial positioning of the upper and lower molds when the molds are closed to prevent the movable mold plate 2 and the fixed mold plate 3 from being damaged due to incorrect positioning. The upper mold stop column 11 and its corresponding lower mold stop column 41 prevent overshoot when the mold is closed.

[0034] The fixed template 3 is arranged directly below the convex template, and a circular arc flanging forming groove 31 is provided on one side of the top of the fixed template 3, which is used to shape the downward circular arc flanging surface on one side of the shock absorber limit cover plate and leave a stamping processing space. A mold positioning groove 32 is provided on the side of the top of the fixed template 3 away from the circular arc flanging forming groove 31, which plays a positioning role when the movable template 2 and the fixed template 3 are molded together. A flanging placement punch platform 33 is provided between the circular arc flanging forming groove 31 and the mold positioning groove 32. The flanging placement punch platform 33 plays a role in positioning, supporting and placing the material plate before mold closing. After mold closing, it plays a role similar to that of a punch in ejecting and guiding the joint required for flanging processing in the middle of the material plate. A guide forming fillet 36 is provided at the top of the arc surface flanging forming groove 31 near the flanging placement punch 33. The top of the fixed mold positioning plate 43 is located on the outside of the flanging placement punch 33 and is surrounded by limiting bosses 34 arranged in a triangle. A positioning hole limiting guide boss 35 is provided between the flanging placement punch 33 and the mold positioning groove 32 at the top of the fixed mold positioning plate 43. The top of the limiting boss 34 and the positioning hole limiting guide boss 35 are round cone-shaped, and the top outer diameter of the limiting boss 34 and the positioning hole limiting guide boss 35 is smaller than the top outer diameter, so as to prevent the left and right position coordinates of the material plate from shifting when the stamping position coordinates change downward, and guide and limit it to the required stamping coordinates.

[0035] The above-mentioned movable template 2 is connected to the bottom end of the movable mold positioning plate 13 through a screw rod, the bottom end of the upper template 1 is located on one side of the movable template 2 and is penetrated by a flanging forming punch 21, and a central flanging forming groove 23 is opened in the middle of the bottom end of the movable template 2, close to the flanging forming punch 21, and the central flanging forming groove 23 is located directly above the flanging placement punch 33. The inner diameter of the central flanging forming groove 23 is larger than the outer diameter of the flanging placement punch 33, which is convenient for mold closing and plays a limiting and guiding role for the joints required for flanging processing of the material plate to be processed. The bottom end of the movable template 2 is located on the side of the central flanging forming groove 23 away from the flanging forming punch 21 and is penetrated by a mold positioning block 22, and the mold positioning block 22 is located directly above the mold positioning groove 32, and the bottom end of the movable template 2 is located on the outer side of the central flanging forming groove 23 and is surrounded by a number of guide holes 24.

[0036] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
