Description

Technical Field

[0001] The utility model relates to the technical field of forming dies, in particular to a springback forming die for a dovetail slider side shaping part. Background Art

[0002] In the design of general high-strength parts, the side wall surface of the product itself has a large springback, the size of the bending surface is large, and the side wall surface is a lapped surface, with very high precision requirements and a small tolerance drawing surface. If the angle difference between the springback of the side wall surface and the product is within 0.5 - 1 degree, there will be a large error in the surface gap, and the parts produced in this way do not meet the drawing requirements at all and cannot be used. If the part is bent at 90 degrees, it is completely infeasible to directly shape the part. At this time, it is considered that the negative angle of the product just becomes 90 degrees after springback. At this time, a side shaping die is often designed to adjust the springback.

[0003] The conventional side shaping die structure uses a standard inclined wedge. A pressure pad is used to press the top surface of the product in the middle. Two side shaping sliders are designed on both sides of the side wall. A fixed punch structure is designed on the lower die. This conventional side shaping die inclined wedge structure has a side shift problem, resulting in unstable part forming quality. Moreover, this standard inclined wedge requires a large die space and high cost. It is impossible to stably position the part before side shaping, and it is also inconvenient to demold after shaping, and it cannot be applied to continuous production. Summary of the Utility Model

[0036] Please refer to Figures 1-5 , the present utility model provides a technical solution: a springback forming die for side shaping parts of a dovetail slider, comprising:

[0037] Die base 1;

[0038] Lower die base 2, which is positioned on the die base 1, and a part 10 to be shaped is positioned on its top;

[0039] Upper die base 3;

[0040] Positioning clamping plate 4, which is elastically and slidably arranged at the bottom of the upper die base 3;

[0041] Slider guide base 5, which is positioned on the lower die base 2, and a dovetail-shaped guide groove 50 is inclinedly arranged on its inner side;

[0042] Sliding seat 6, the dovetail slider 60 on its outer side is inclinedly slidably arranged on the dovetail-shaped guide groove 50, and a downward pressing notch 61 is arranged at the inner bottom edge;

[0043] Ejector block 7, whose end is positioned on the upper die base 3 and slidably penetrates through the positioning clamping plate 4, and corresponds to the sliding seat 6;

[0044] Support base 8, which is arranged below the sliding seat 6 and elastically provided with a knockout pin 81.

[0045] An inner guide post 32 is arranged on the upper die base 3, the inner guide post 32 is inserted into the slot of the positioning clamping plate 4, and the upper die base 3 and the positioning clamping plate 4 are elastically connected by a plurality of elastic members 31.

[0046] A clamping plate 40 is arranged at the bottom of the positioning clamping plate 4, a second positioning portion 41 is arranged on the surface of the clamping plate 40, a clamping groove 42 is arranged on its outer side, a first positioning portion 22 is arranged on the lower die base 2, the second positioning portion 41 and the first positioning portion 22 are convex or concave structures, the edge of the part 10 to be shaped is sleeved or inserted on the lower die base 2, the clamping plate 40 and the clamping groove 42, and the surface of the part 10 to be shaped is joined on the second positioning portion 41 and the first positioning portion 22.

[0047] Arc-shaped grooves 52 are symmetrically arranged at the edges of the dovetail-shaped guide groove 50, and the arc-shaped grooves 52 are slidably connected to the arc-shaped flanges 63 of the dovetail slider 60.

[0048] A docking groove 51 is arranged in the center of the dovetail-shaped guide groove 50, and the docking groove 51 is slidably connected to the limiting block 62 of the dovetail slider 60.

[0049] A thimble 21 is elastically arranged in the groove of the lower die base 2.

[0050] The working principle of a dovetail slider side shaping part springback forming die in this embodiment includes: during use, the part 10 to be shaped is fed to the lower die base 2 through a progressive die. The upper die base 3 is driven to move downward and close the die. The positioning clamping plate 4 first elastically abuts against the part 10 to be shaped and presses it on the lower die base 2. The part 10 to be shaped is positioned through the cooperation of the clamping plate 40, the clamping groove 42, the first positioning portion 22 and the second positioning portion 41. The positioning clamping plate 4 is pressed and moves upward toward the upper die base 3 guided by the inner guide post 32. As the upper die base 3 continues to move downward, the top block 7 is exposed from the bottom surface of the positioning clamping plate 4 and presses on the top surface of the slide block 6. The slide block 6 is pressed and moves downward along the slider guide 5. Through the dovetail sliding structure, the function of preventing the wedge-shaped slider from side shifting is realized, ensuring stable downward inclined and inward sliding. During this period, the downward pressing notch 61 performs multi-point docking and pressing on the edge of the part 10 to be shaped, causing it to fold. Finally, the slider guide 5 moves to the bottom, its bottom surface abuts against the support base 8, and its inner side laterally abuts against the surface of the folded end of the part 10 to be shaped, realizing multi-faceted positioning and ensuring the quality of the part side shaping. After processing is completed, the upper die base 3 moves upward to reset. The slide block 6 is jacked up by the ejector pin 81 and resets upward and outward along the slider guide 5. The clamping plate 40 is delayed from demolding under the elastic force of the elastic member 31. When the upper die base 3 moves to a certain position, the positioning clamping plate 4 rises and demolds, and stable demolding of the bottom of the part is realized through the thimble 21. This die can be applied to continuous shaping processing by a progressive die, and the processing and forming quality is stable.

[0051] In summary, due to the adoption of the above technical solutions, a dovetail slider side shaping part springback forming die in this embodiment has the following beneficial effects compared with the prior art:

[0052] The die of the present utility model realizes simultaneous die closing and part positioning through the elastic sliding design of the upper die base and the positioning clamping plate. The dovetail-shaped wedge is slidably arranged to avoid side deviation of the wedge structure during sliding, ensuring the stability of guiding transmission and forming, and cooperating with the thimble to realize segmented demolding synchronous with the die, avoiding damage to the part and affecting its forming quality. This die is applicable to continuous production, the die structure is convenient for replacement, the die structure is simplified, the size is small, and the cost is low.
