Background

The channel (Hafengro) is an embedded part for buildings, and is riveted and matched with a rivet to play a role in connection and fixation, and the riveting of the channel and the rivet needs a riveting machine. Because the hydraulic system can provide continuous and stable high pressure, the pressing mechanism and the riveting mechanism of the existing riveting machine are both hydraulic oil cylinders. However, the adoption of the structure needs to configure a complete set of hydraulic power system, which is expensive, and the production cost of enterprises is undoubtedly increased; moreover, since the riveting frequency is high and needs to reach about 30 times per minute, the oil tank is required to be large in size (about 500 widths x500 heights x1500 lengths), and a hydraulic oil cooler needs to be added, so that the whole equipment is large in size (about 1500 widths x4000 lengths x1200 heights), and a large installation space is occupied. If the hydraulic oil cylinder is replaced by the air cylinder, the problems are effectively solved, but the air compressibility is good, the rivet is poor in pressing effect, and the problem of resilience of the upper die is easy to occur during riveting; moreover, the impact force required during riveting can not meet the requirement, so that the riveting effect is influenced, and the quality of the product is reduced.
