Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of automobile part processing, in particular to a door handle and outer panel hole flanging tool. BACKGROUND
[0002] With the rapid development of the automobile industry, the automobile manufacturing process level is continuously improved, and consumers have higher and higher requirements for the appearance and performance of automobiles. In order to meet market demand, new automobile technologies are emerging in an endless stream, and the hidden door handle is the most typical example.
[0003] The hidden door handle can not only reduce wind resistance compared with the traditional door handle, but also enhance the overall technological sense of the automobile, and the modeling is also more beautiful, so the hidden door handle is favored by more and more consumers. However, the manufacturing difficulty of the hidden door handle outer panel is greatly increased compared with the traditional door handle outer panel, because the positioning between processes is particularly important during the stamping process of the outer panel, and inaccurate positioning can cause a series of appearance defects such as the A surface of the outer panel being crushed and the characteristic edge line being discontinuous. The hidden door handle outer panel stamping process faces the problem of difficult positioning.
[0004] As shown in Figures 5 to 7 , the stamping die of the traditional door handle outer panel 01 usually designs positioning pins at the through hole 012 of the water cutting part 011 and the door handle mounting hole 013 for inter-process positioning, and both are indispensable. However, as shown in Figures 8 to 10 , the door handle area of the hidden door handle is a hole flanging structure 04. The hole flanging structure 04 of the hidden door handle needs to be pre-punched before being hole flanged, so the positioning of the hidden door handle outer panel 8 during the stamping process can only choose the pre-punching hole 81 on the hidden door handle outer panel 8 for positioning. However, the depth of the pre-punching hole 81 is very shallow, so the positioning pins designed on the existing stamping die in the door handle mounting hole 013 cannot be applied to the stamping process positioning of the hidden door handle outer panel 8, and directly removing the positioning pins on the stamping die will cause the problem of being unable to realize positioning, resulting in low precision of the hole flanging structure of the hidden door handle.

[0052] The driving module 7 and the positioning pin 9 are arranged side by side on the sliding component 6. In order to avoid the influence of the driving module 7 on the positioning precision of the positioning pin 9, a certain gap is provided between the driving module 7 and the positioning pin 9.
[0053] In order to ensure the balance of the supporting force received by the sliding component 6 and avoid deviation of the sliding component 6 during the upward and downward sliding process, two positioning pins 10 are arranged side by side and oppositely on the fixed mounting plate 4, and an elastic component 5 is sleeved on each positioning pin 10.
[0054] In order to ensure the stability of the connection, a connecting piece 13 is used to fix the driving module 7 and the positioning pin 9 on the sliding component 6.
[0055] In the embodiment, the elastic component 5 is a spring, and the connecting piece 13 is a bolt.
