Digital display high and low pressure pump riveting machine hydraulic station and riveting process

Abstract

The invention discloses a digital display type high-low pressure pump riveting machine hydraulic pressure station and a riveting process, and belongs to the field of machining. The digital display type high-low pressure pump riveting machine hydraulic pressure station comprises an oil tank, a low pressure oil pump set loop, a high pressure oil pump set loop, a cooling device and an electrical control gear. The low pressure oil pump set loop comprises a first motor, a low pressure oil pump and a low pressure overflow valve assembly; a low pressure oil way at the output end of the low pressure oil pump is divided into two ways; and one way is connected to an oil return tank through the low pressure overflow valve assembly, and the other way is connected with a rivet pincer oil cylinder through a first one-way valve and an electro-hydraulic directional control valve. The high pressure oil pump set loop comprises a second motor, a high pressure oil pump and a high pressure overflow valve assembly; a high pressure oil way at the output end of the high pressure oil pump is divided into two ways; and one way is connected to the oil return tank through a second one-way valve and the high pressure overflow valve assembly, and the other way is gathered with the lower pressure oil way through the second one-way valve to be connected with the rivet pincer oil cylinder through the electro-hydraulic directional control valve. By means of the digital display type high-low pressure pump riveting machine hydraulic pressure station and the riveting process, through ingenious combination of the low pressure oil pump and the high pressure oil pump, the aim of riveting of rivets is achieved; the structure is more simplified and advanced; and in addition, the riveting speed is high, generated heat is less, and noise is low.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a digital display high and low pressure pump riveting machine hydraulic station and a riveting process. 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. The most widely used riveting machine on the market is a pressurized riveting machine, and its hydraulic station is composed of quantitative pump + cartridge valve + booster cylinder. The most important feature of the so-called supercharged riveting machine is that it can boost the lower pressure output by the quantitative pu...
