Description

Technical Field

[0001] This utility model patent relates to the field of automotive processing technology, and in particular to a drawing die for automotive chassis parts. Background Technology

[0002] Current drawing dies have structural design limitations, often causing workpiece positioning deviations during stamping. This misalignment makes it difficult for the formed part to effectively fit the die cavity assembly, resulting in insufficient forming accuracy of the triangular arm edge contour. More importantly, unintended displacement can also cause mechanical interference between the die and the workpiece, significantly affecting the stability of the formed part's geometry and leading to process defects such as sticking and jamming during demolding, ultimately drastically reducing production cycle efficiency.

[0003] Existing patent CN221952146U mentions a drawing die for automotive chassis control arms. While this solves some of the problems, manual intervention is still required during the demolding stage. This manual intervention affects stability and reduces work efficiency. Therefore, there is a need for a drawing die that can achieve full automation and improve production efficiency. Summary of the Invention

Detailed Implementation

[0021] The present invention provides a further description of a drawing die for automotive chassis components, in conjunction with the accompanying drawings.

[0022] As shown in the attached figure, this is a drawing die for automotive chassis parts, including a support frame 7 and a base 17. An upper push cylinder 2 is fixedly installed on the base 17. A lower template 4 is fixedly installed at the output end of the upper push cylinder 2. A lower punch 16 is provided on the lower template 4. A pressure ring 13 is provided at a corresponding position directly above the lower template 4. An upper template 12 is provided at a corresponding position directly above the pressure ring 13. An upper die is provided on the upper template 12. A cutter groove 15 is provided on the upper template 12. The output end of a lower press cylinder 14 is fixedly installed on the top surface of the upper template 12. A cutter plate 6 is provided at a corresponding position directly above the upper template 12. A cutting blade 10 is provided below the cutter plate 6.

[0023] Furthermore, the output end of the propulsion cylinder 9 is fixedly installed above the cutter plate 6.

[0024] Furthermore, the fixed ends of both the propulsion cylinder 9 and the downward cylinder 14 are fixedly mounted on the top of the support frame 7.

[0025] Furthermore, a guide rod 11 is fixedly installed at the base 17, and the upper template 12, the pressure ring 13, and the lower template 4 all pass through the guide rod 11 to achieve positioning and guidance.

[0026] Furthermore, a stop block 5 is fixedly installed on the inner side wall of the support frame 7. The stop block 5 is located between the lower template 4 and the pressure ring 13. A spring 8 is installed between the stop block 5 and the pressure ring 13, and a spring 8 is installed between the stop block 5 and the lower template 4.

[0027] Furthermore, the base 17 has grooves 1 on the left and right sides, and sealing strips 3 are fixedly installed on both sides of the grooves 1.

[0028] The working principle of this utility model is as follows: In the initial state, the upper template 12, the pressure ring 13, and the lower template 4 all pass through the guide rod 11 for positioning and guidance. The pressure ring 13 is lifted upward by the spring force of the spring 8, placing the iron plate to be drawn above the pressure ring 13. As the upper template 12 moves downward, the upper die contacts the pressure ring 13, the iron plate to be drawn is pressed, the spring 8 is further compressed, driving the pressure ring 13 to begin moving downward, the sheet gradually contacts the lower punch 16, and the upper push cylinder 2 of the lower template 4 pushes upward, starting the drawing process; after the upper template 12 moves, it contacts the stop block 5, ending the movement. Then, the cutter plate 6 moves downward under the action of the push cylinder 9, and the cutter 10 cuts the drawn iron plate, realizing the integrated operation from drawing to cutting. After the cutting is completed, the lower press cylinder 14 of the upper template 12 retracts, the upper template 12 rises, the spring 8 springs up, pushing the pressure ring 13 and the drawn iron plate for easy removal and collection.
