Technology of Riveting Pedal Arm with Riveting Die

Abstract

The invention relates to riveting processes of automobile equipment, in particular to a process for riveting a pedal arm through a riveting die. The process specifically comprises the following steps that a riveting pipe is arranged on a correction core of a lower die in a sleeved mode, a pedal piece is arranged on the riveting pipe in a sleeved mode, the pedal piece is placed flatly on a lower die discharge plate and is guided by a guide column, an upper die device moves downwards, an upper die discharge plate is driven to move downwards until the upper die discharge plate is in contact with the pedal piece, to be riveted, attached to the lower die discharge plate in a compressing mode, prepressing is formed, the upper die device continues to move downwards until an upper die core and a lower die core are fully matched, a riveting upper die device moves upwards, the die is opened, the upper die discharge plate moves downwards, the lower die discharge plate moves upwards, and the pedal piece is discharged. According to the process, an original insert is divided into two parts through the riveting die of the pedal arm, design is reasonable, replacement cost is lowered, and meanwhile due to the fact that the guide column is arranged between the upper die device and a lower die device, it can be firmly guaranteed that riveted plates do not shift after die assembling is carried out on the upper die device and the lower die device.

Description

technical field [0001] The invention relates to a riveting process of automobile equipment, in particular to a process of riveting a pedal arm by using a riveting die. Background technique [0002] The existing riveting process is to connect the riveting pipe and the pedal arm by riveting. In order to ensure that the riveted tube can be arranged in the pre-punched hole, the diameter of the pre-punched hole is 0.5mm larger than the diameter of the riveted tube. At present, the upper and lower mold inserts of the riveting mold in the process of riveting the pedal arm with the riveting mold are relatively large. Although it is more convenient to replace, the cost of each insert is relatively large. Considering the actual working surface, that is, the area that is easy to wear It's just a part of it, so it needs to be designed reasonably to reduce costs. Contents of the invention [0003] The technical problem to be solved by the present invention is: Based on the above prob...
