Hydraulic energy-storing device used for light steel keel machining

Abstract

The invention discloses a hydraulic energy-storing device used for light steel keel machining. The problems that in the prior art, a hydraulic system energy-storing device is poor in energy-storing effect and airtightness, and a hydraulic pump is low in working efficiency and prone to be broken down due to the fact that pressure change of the energy-storing device is frequent are solved. According to the spring-type energy-storing device, a spring is obliquely arranged and slides in a slide groove to achieve contraction and extension, and the buffer effect and the energy supplement function are achieved. A wave-shaped flow guide plate improves the energy-storing effect, and a plurality of movable seal rings improve the sealing property. A low-pressure energy-storing device unit and a high-pressure energy-storing device unit are arranged correspondingly, through the low-pressure energy-storing device unit, the auxiliary power function and the middle buffer effect are achieved, and through the high-pressure energy-storing device unit and a second piezometer, pressure supplement treatment of the hydraulic pump is controlled, and the condition that the hydraulic pump frequently conducts pressure supplement treatment and pressure supplement stopping treatment on a hydraulic system is avoided, so that working efficiency of the hydraulic system is improved, and the occurring possibility of device failures is reduced. The hydraulic energy-storing device used for light steel keel machining is simple in structure and scientific in design.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a hydraulic energy storage device used for processing light steel keels. Background technique [0002] The hydraulic system occupies an important position in the light steel keel processing equipment. The punching, marking and cutting of the keel are all done by the hydraulic system in the light steel keel processing equipment. Since there are many types of keels, the thickness of the steel strips used for different types of keels is also different, which causes the load of the hydraulic cylinder in the hydraulic system to vary with the product; in addition, for different types of keels, the forming speed, fixed The length of the ruler and the number of punching holes for each keel are all changed, so the flow rate and movement interval of the hydraulic cylinder are also changed. [0003] In the prior art, the hydraulic system used in the light steel keel proces...

AI Technical Summary

Problems solved by technology

The traditional spring-type accumulator is a vertical spring, which has poor energy storage effect and insufficient energy release; a single-layer sealing ring is used, and its sealing performance is not high

Moreover, when the pressure in the accumulator changes frequently, the hydraulic pump frequently performs pressure supplementation and stops pressure supplementation of the hydraulic system, resulting in low work efficiency and easy equipment failure

[0004] Therefore, a hydraulic energy storage device for light steel keel processing is provided, which solves the problem of poor energy storage effect of the hydraulic system accumulator, insufficient energy release, poor sealing performance, and frequent pressure changes of the accumulator in the prior art. The problem of low work efficiency and prone to equipment failure has become an urgent problem to be solved by those skilled in the art
