Riveting machine according to the different power mode can be divided into pneumatic riveting machine and hydraulic riveting machine. This is a new type of riveting equipment, which is made according to the principle of cold rolling, and its main purpose is to use rivets to rivet items together. The riveting machine is mainly assembled by rotation and pressure, and is mainly used in areas that require riveting. It has the characteristics of stable performance, compact structure, convenient and safe operation.

Pneumatic riveting machine is a kind of riveting machine, refers to the mechanical equipment that can rivets the items, and the riveting machine mainly relies on rotation and pressure to complete the assembly work. Pneumatic riveting machine is the most advanced riveting tool in China. Suitable for automobile, train, ship, aviation and other sheet metal fastening structure industry; Computer cases, electrical cases, kitchen cabinets, etc. must be drawn and fastened; Aluminum doors and Windows, upholstery, etc. are tight.

The structure of hydraulic riveting machine and pneumatic riveting machine is basically the same, spindle, piston, spindle bearing, riveting head assembly, closed height adjustment device, spindle barrel, control box and workbench, etc. The main difference between them is that the pneumatic riveting machine is a cylinder, and the hydraulic riveting machine is a hydraulic cylinder. The pneumatic riveting machine is equipped with a solenoid valve and an air source processing element, while the hydraulic riveting machine is a hydraulic system including an overflow valve, a hydraulic pump, a throttle valve and an oil circuit block. Because the hydraulic riveting machine uses a low pressure system, the hydraulic pump equipped with the hydraulic riveting machine is a gear pump, and the M-type three-four-way electromagnetic reversing valve can make the riveting head of the riveting machine hover at any position within the stroke.
