Abstract

The invention discloses a pressing rivet method used for pressing rivet of a material part. The material part comprises a first pipe and a second pipe which can be in abut joint, and the pressing rivet method comprises the following steps that the first pipe is located over the second pipe, and the first pipe is sleeved with a limiting mechanism; the first pipe is released, the first pipe falls off through gravity of the first pipe and is in abut joint with the second pipe, and the first pipe is sleeved with the limiting mechanism; vertical downward acting force is provided for the first pipein abut joint with the second pipe, the first pipe in abut joint with the second pipe is in abut joint to the second pipe to form an abut-joint part; and the abut-joint part of the abut-joint part isextruded, and riveting is achieved. The method at least comprises the following advantages that when two workpieces are in abut joint, abut-joint precision of two workpieces can be well ensured, and pressing rivet precision is improved.

Description

technical field [0001] The invention relates to the technical field of riveting, in particular to a riveting device and method for riveting materials. Background technique [0002] The statements in this section only provide background information related to the present disclosure and may not constitute prior art. [0003] Riveting is a method of using axial force to press at least two workpieces so that the two are connected and fixed. From the perspective of riveting, it can be divided into spin riveting and pressure riveting. At present, most of the riveting methods of the transmission adopt the method of pressure riveting. In the process of pressure riveting, two workpieces are usually clamped separately and then butt-jointed and squeezed. During the above-mentioned operation process, the precision requirements for the butt joint of the two workpieces are very high, and deviations usually occur, resulting in unqualified riveting and high production costs. [0004] It s...
