Description

Multi-step riveting and forming equipment

technical field

The utility model relates to a multi-step riveting forming equipment, in particular to a multi-point riveting product processing equipment with relatively high material hardness.

Background technique

At present, the non-detachable multi-point connection method in China is welding, which is easy to cause large residual deformation and welding internal stress. There are a certain number of defects in welded joints, such as cracks, pores, slag inclusions, incomplete penetration, incomplete fusion, etc. The existence of defects will reduce the strength, cause stress concentration, and damage the compactness of the weld, which is one of the main reasons for the damage of the welded structure. Welded joints have large performance inhomogeneities. Because the composition and metallographic structure of the weld are different from the base metal, the thermal cycles experienced by each part of the joint are different, which makes the performance of the joint in different areas different. During the welding process, high temperature, strong light and some harmful gases harmful to human body are produced.

Contents of the invention

The utility model mainly solves the deficiencies in the prior art, and provides a forming equipment that adopts multiple riveting in the processing process.

The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions:

A multi-step riveting forming equipment, including a connecting piece, on which at least 3 sets or more of pressing wheel mechanisms are attached, and a cover plate is crimped between the connecting piece and the pressing wheel mechanism, and the pressing wheel mechanism includes a final pressing plate, and a final pressing plate The end of the pressure wheel is provided with two laterally arranged pressure wheels, and the pressure wheel is provided with an outwardly protruding pressure block, and the end of the pressure block is provided with a cutting edge. The blade of the first pressure wheel in the pressure wheel mechanism The mouth is cone-shaped, and the cutting edges of the remaining pressure rollers are conical planes that increase in turn. The multi-step riveting and forming equipment described here is to attach at least 3 sets of pressure roller mechanisms on the connecting piece. The pressure roller mechanism is driven by a machine. According to the needs of the product, the cutting edge of the first pressure roller is conical, and a small groove needs to be opened on the cover plate. , the back pressure wheel gradually rivets the protruding point into the required shape through different cutting edges, multiple times of riveting, so that the shear force that the product can withstand is enhanced, and the product will not produce residual deformation and welding internal stress , can avoid cracks due to stress concentration.

As a preference, the pressure roller in the pressure roller mechanism is inserted into the pressure shaft piece, the pressure roller is cylindrical, the pressure block is arranged at the center of the outer wall of the pressure roller, and the two ends of the outer wall of the pressure roller are respectively A briquetting block is provided, the briquetting block is opposite to each other, and the briquetting block is integrated with the pressure wheel. There are two cutting edges on the two side walls of the pressure roller. When there is a problem with one cutting edge, it can be replaced and turned in the other direction to use a new cutting edge for riveting.

Preferably, both ends of the end portion of the pinch piece are provided with inner chamfers, and the pressure roller mechanisms are matched and corresponded to each other.

Therefore, the utility model provides a multi-step riveting forming equipment, which has high product stability, strong shearing force, protects the health of employees, and consumes less energy.
