Problems solved by technology

However, in actual processing, it is found that in order to allow the bayonet of the beam 2 to be placed in the groove 11, the design width of the bayonet is generally smaller than the width of the groove 11, and the reduction of the opening width of the groove 11 after riveting is relatively limited. As a result, the crossbeam 2 is still easy to fall out of the opening, and it is time-consuming and laborious to perform detection and manual adjustment

Embodiment Construction

[0025] The present invention will be further described in conjunction with the specific embodiments.

[0026] like image 3 with Figure 4 As shown, a U-shaped beam riveting process of the present invention includes:

[0027] 1 tape strip strip: For the metal tape, the contour is diced without completely cut, and two recess 11 used to assemble the beam 2;

[0028] 2 Material U-bending: U-shaped bent is performed as a reference feed surface as a reference surface, forming two facing surface 12 of each other;

[0029] 3U-shaped parts falling: cutting the main body of the U-shaped parts 1 from the material tape;

[0030] 4 Beam assembly: the bayonet card on both ends of the beam 2 into the groove 11;

[0031] 5 riveting: The U-shaped member 1 groove 11 containing the beam 2 is placed upward in the riveting machine, and the inlet edge of the groove 11 is pressed and deformed, and the beam 2 is stuck;

[0032] The shape of the tape strip section increases the projection portion 13 on bot...

Abstract

The invention belongs to the technical field of metal parts manufacturing, and relates to a riveting process for U-shaped beams. In the punching step, protrusions are added to the edges of both sides of the opening of the groove to which the beam will be assembled, and in the riveting step, a riveting punch is used to flatten the protrusions and deform to the inside of the groove. In the punching step of the process, a raised portion is designed on the edge of the opening of the groove that needs to be riveted, so that in the riveting step, there is material to form an effective barrier to the beam, and the assembly quality is improved.

Description

Technical field [0001] The present invention relates to the field of metal stamping processing, and more particularly to a U-shaped beam riveting process. Background technique [0002] With the continuous development of my country's stamping technology, the pressure on the automotive market is constantly increasing, and many foreign imports will be domesticated. [0003] figure 1 It is a U-shaped member 1 for a car seat belt winding device, and its body is a U-shaped member that is bent by a stamped bent, and a groove 11 is provided on the two reliabers 12, In the groove 11, the beam 2 is assembled at both ends, which can make the entire structural strength. like figure 2 As shown, in order to combine the two, the general practice is to extrude the blade of the groove 11 by the riveting punch 3, so that the inner side is deformable, so that the beam 2 is removed from the opening of the recess 11 to disengage. However, in the actual processing, in order to allow the bayonet 2 of ...
