Embodiment Construction

[0017] Such as figure 1 , 2 As shown in , 3, a highly integrated riveting machine hydraulic device includes a fuel tank 1, an oil pump motor device 2, an electrical control device 5 and a boost control device, and the electrical control device 5 is fixed on the side of the fuel tank 1. The oil pump motor device 2 includes an oil pump 10 and a motor 9. The motor 9 is installed vertically on the upper cover of the fuel tank. It can reduce noise and reduce heat; the booster device 4 and the oil pressure integrated control device 3 are installed together through a high-precision oil pressure integrated block to form a booster control device, and the booster control device is installed on the upper cover of the fuel tank.

[0018] Such as Figure 4 , 5 As shown, the overflow valve 13, the main reversing valve 14, the pressure boosting reversing valve 16, and the rivet switching valve 22 are integrated on the upper surface of the high-precision oil pressure manifold 25; the press...

Abstract

The invention relates to a highly integrated hydraulic device for a riveting machine, which comprises an oil tank, an oil pump motor device, an electrical control device and a pressurization control device. The oil pump motor device comprises an oil pump and a motor; the motor is vertically arranged on an oil tank upper cover; the oil pump is arranged in hydraulic oil of the oil tank; a pressurization device and an oil pressure integrated control device are arranged together by a high accuracy oil pressure integration block to form the pressurization control device; and the pressurization control device is arranged on the oil tank upper cover. Compared with the prior art, not only is the problem of oil leakage of joints, which is caused by the adoption of a plurality of integration blocks in an original plate valve, avoided, but also the defect of difficulty in processing and manufacturing a valve block of a cartridge valve is avoided. By comparison, the oil pressure integration block adopted in the invention is easier to manufacture, a hydraulic pipeline is shortened, the oil leakage is reduced, heat emission is reduced, the working efficiency is greatly improved, and noise and the like which are generated in the working process can be inhibited.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a hydraulic device for a riveting machine. Background technique [0002] At present, there are two types of riveting machines produced in China according to the power source, namely hydraulic riveting machines and pneumatic riveting machines. Due to the limitation of low pneumatic pressure, the pneumatic riveting machine can only be used in occasions with low riveting pressure, while the hydraulic riveting machine is widely used in various industries due to its wide pressure range. There are mostly two types of hydraulic valves used in the hydraulic device (ie hydraulic station) of the hydraulic riveting machine, namely plate valves and cartridge valves. Since there are many hydraulic valves in the hydraulic system of the riveting machine, the structure of the plate valve adopts multiple integrated blocks superimposed together, and the hydraulic valves are ...
