Bidirectional and synchronous riveting method of U-type section part

Abstract

The invention provides a bidirectional and synchronous riveting method of a U-type section part. The method comprises the specific steps that (1), accurate positioning is carried out between a left workpiece to be riveted and the U-type section part and between a right workpiece to be riveted and the U-type section part; (2), rivets are manually installed outwards from an inner cavity of the U-type section part; (3), a middle pneumatic compression resistance cushion block extends into the inner cavity of the U-type section part, the two side faces of the middle pneumatic compression resistance cushion block just make contact with the outer ends of the head portions of the rivets on the two sides; (4), synchronous riveting is carried out on the two rivets corresponding to each riveting position in sequence through a bidirectional hydraulic synchronous rivet clamp, the middle pneumatic compression resistance cushion block bears the symmetrical riveting force at the same time to achieve the bidirectional and synchronous riveting, the middle pneumatic compression resistance cushion block is retracted, positioning is released, and then the bidirectional and synchronous riveting of the U-type section part is finished. According to the bidirectional and synchronous riveting method of the U-type section part, the bidirectional hydraulic synchronous rivet clamp is combined with the middle pneumatic compression resistance cushion block, the bidirectional riveting function of the U-type section part is achieved ingeniously, and the efficiency is high.

Description

technical field [0001] The invention relates to a two-way synchronous riveting method for U-shaped cross-section parts, and is especially suitable for occasions where small or narrow U-shaped cross-section parts cannot be riveted by traditional one-way riveting technology. Background technique [0002] At present, the riveting process of domestic auto parts adopts the traditional one-way riveting method, such as horizontal one-way riveting pliers, vertical one-way riveting pliers; when small or narrow U-shaped cross-section parts need to be riveted, Since the external dimension of the static riveting seat of the traditional one-way riveting pliers is much larger than the U-shaped cross-section size of the part, it cannot enter the cavity of the U-shaped cross-section part for riveting. Therefore, the traditional one-way riveting method is not only applicable to There are greater limitations, and its riveting efficiency is also low. Contents of the invention [0003] In or...
