Riveting machine (also known as rivet machine, rotary riveting machine, riveting machine, rolling riveting machine, etc.) is a new riveting equipment developed based on cold rolling principle. The equipment has the advantages of compact structure, stable performance, convenient operation and safety. Compared with the traditional backward riveting process, it has the following obvious advantages.

Main advantages:

The rivet forming force is small, only 1/10 of the punch riveting, and the workpiece has no bad deformation after riveting.

The riveting surface of automobile parts riveting machine is clean and beautiful.

No vibration, low noise, low energy consumption, easy and safe operation.

High efficiency, low cost.

Easy to automate.

Riveting machine is widely used in automobile manufacturing, textile equipment, electrical switch, hardware tools, instruments and meters, steel furniture, daily equipment and other required riveting process occasions. At present, there are two series of rotary roll (BM), radial (JM), vertical, desktop, horizontal three forms of more than ten specifications of the series of products. All shapes can be riveted as long as the right riveting head is made.

How to control the quality of the riveting process

1, pressure riveting process processing content: pressure riveting nuts, screws, studs and custom hardware pressure riveting parts (guide pins, positioning support columns, etc.), electrostatic hand bowl, pressure riveting wrench, etc.

2. For the riveting parts close to the edge of the product or the periphery of the hole, the edge of the product or the periphery of the hole will be obviously deformed after the riveting, according to the deformation of the material to take corresponding measures (such as shape correction/or grinding) to meet the requirements of the size and appearance of the drawings.

3. After riveting, there shall be no distortion or deviation. It is necessary to ensure that the thread is concentric with its corresponding hole.

4, pressure riveting parts of the material, specifications and models must be consistent with the drawings, not wrong specifications;

5, after the pressure riveting pressure riveting parts around shall not be raised or depression obvious deformation, shall not have obvious surface treatment can not cover the imprint or mold.

6, after the pressure riveting shall not tilt the pressure riveting parts shall not loose, fall off, must test its firmness; The value of push, pull and torsion must meet the requirements specified in PEM of the riveting parts.

7. Before pressing riveting, we must timely confirm whether the external identification of pressing riveting parts used by the production line and the physical object (material, specification and model) in the packaging bag meet the requirements of the drawings, and whether there is a mixing phenomenon in the packaging bag.

8, for in the bending edge or die forming edge of the close pressure riveting parts to pay attention to, especially thread, appearance (deformation) to focus on detection.
