[0037] Specifically, the cylinder 201a-1 is fixedly mounted on the top of the mounting base 101, and the output shaft of the cylinder 201a-1 is fixedly mounted with a slider 201a-2. The slider 201a-2 is trapezoidal, with a large bottom area close to the cylinder 201a-1, and the hypotenuse side faces upward. A connecting column 201a-3 is fixedly mounted on the slider 201a-2. There are two connecting columns 201a-3, and bearings 201a-4 are fixedly mounted at both ends of the connecting column 201a-3.

[0042] Operation process: When in use, after the automobile plate is formed, the cylinder 201a-1 is started, and the cylinder 201a-1 drives the slider 201a-2 to move on the guide rail. When the slider 201a-2 pushes away from the cylinder 201a-1, the connecting column 201a-3 on the slider 201a-2 moves on the long hole 201b-3. Since the long hole 201b-3 is placed obliquely, the movement of the connecting column 201a-3 drives the push plate 201b-1 to move upward. At this time, the formed product is separated from the push plate 201b-1 under the action of the push plate 201b-1. Out of the mold groove 301c, when the product is out of the mold groove 301c, the cylinder 201a-1 is used to pull the slider 201a-2 to move toward the cylinder 201a-1, and the connecting column 201a-3 on the slider 201a-2 moves on the long hole 201b-3, driving the push plate 201b-1 to move downward, so that the push plate 201b-1 returns to its initial position. The whole operation can quickly and automatically push the formed product after the automobile panel is formed, which is convenient for the staff to take the material, improves the processing efficiency and reduces the manufacturing cost.
[0043] Example 2
[0044] Reference Figure 1-Figure 4 , which is the second embodiment of the utility model.

[0047] Specifically, the fixed column 203a is fixedly installed on the mounting base 101, the fixed column 203a of each group of supporting components 203 has different lengths, and each group of supporting components 203 has two fixed columns 203a, a sliding groove 203b is opened in the fixed column 203a, the diameter of the bottom of the sliding groove 203b is larger than the diameter of the top, a sliding column 203c is arranged in the sliding groove 203b, a baffle is arranged at the bottom of the sliding column 203c, the diameter of the baffle is the same as the diameter of the bottom of the sliding groove 203b, the diameter of the sliding column 203c is the same as the diameter of the top of the sliding groove 203b, the baffle can prevent the sliding column 203c from escaping from the sliding groove 203b when sliding in the sliding groove 203b, and a support plate 203d is fixedly installed on the top of the sliding column 203c, and the arc surface 102 on the top of the support plate 203d is the same as the arc surface 102 of the separation convex blade 301e.
[0048] The rest of the structure is the same as that of Example 1.
[0049] Operation process: During use, when the cylinder 201a-1 controls the slider 201a-2 to drive the push plate 201b-1 to move up and down, the vertical plates 201b-2 at both ends of the bottom of the push plate 201b-1 move synchronously, and the vertical plates 201b-2 drive the linkage rods 202b on both sides to move up and down. The linkage rods 202b drive the support plate 203d to move up and down, which can push the automobile panel at the edge of the mold groove 301c away from the ejection groove 301c. The support assembly 203 is used to assist the lifting assembly 201 to push the automobile panel out of the mold groove 301c.
[0050] Example 3
[0051] Reference Figure 1-Figure 7 , which is the third embodiment of the utility model. Different from the above embodiments, this embodiment provides a local stress release device, including the above-mentioned ejection mechanism during the drawing process, and also includes a mold component 300, including a lower mounting component 301 arranged on the mounting component 100, and an upper mounting component 302 arranged above the lower mounting component 301.
[0052] Furthermore, the lower mounting assembly 301 includes a lower mounting plate 301a disposed below the mounting component 100, a lower mold base 301b disposed on the lower mounting plate 301a, a mold groove 301c opened on the lower mold base 301b, and a push plate hole 301d opened on the mold groove 301c; wherein, a separation convex blade 301e and a material receiving convex blade 301f are provided at the top of the mold groove 301c.
[0053] Specifically, a lower die base 301b is fixedly installed above the lower mounting plate 301a, a die groove 301c is opened on the top of the lower die base 301b, and a push plate hole 301d is opened at the bottom of the die groove 301c. The push plate hole 301d facilitates the push plate 201b-1 and the support plate 203d to push the product away from the die groove 301c. A separation convex blade 301e and a material receiving convex blade 301f are arranged on the top of the die groove 301c. The separation convex blade 301e and the material receiving convex blade 301f are special surfaces. The main function of the separation convex blade 301e is to separate the sheet material and release stress. The material receiving convex blade 301f is arranged at the end of the separation convex blade 301e, and is used to deform the waste material after the stress is released, thereby eliminating the risk of scraping the waste material to produce iron filings.
[0054] Furthermore, the upper mounting assembly 302 includes an upper die base 302a disposed on the lower die base 301b, and an upper mounting plate 302b disposed on the upper die base 302a; wherein a material ejecting convex blade 302c is disposed on the upper die base 302a.
[0055] Specifically, the upper die base 302a is placed on the top of the lower die base 301b, and an upper mounting plate 302b is fixedly installed on the upper die base 302a, wherein a material collecting convex blade 301f is fixedly installed on the top of the upper die base 302a. The material collecting convex blade 301f is a convex blade added to the die surface with a cutting edge parallel to the stamping direction. The height is 5mm higher than the bottom height when the thinning rate reaches 20%. It is independently designed to be an irregular shape according to the distribution range of the thinning rate exceeding 20%. Its main function is to provide concentrated stress to the waste area where stress needs to be released during the drawing process.
[0056] The rest of the structure is the same as that of Example 2.
[0057] Operation process: When in use, when the press drives the upper die base 302a to move, the ejecting blade 302c pushes the taut sheet material onto the edge of the separating blade 301e. Under the action of stress concentration, the sheet material produces a fracture to achieve local stress release, and continues to drive the waste material downward to bend under the action of the collecting blade 301f, so that the waste material is away from the separating blade 301e. The device has no sharp blade, and the maintenance process reduces the risk of cuts during the process, with higher safety performance. The ejecting blade 302c eliminates the risk of scraping waste to produce iron filings, and has less efficiency loss. Compared with other stress release methods, the device has lower development costs and lower operating costs.
