Compressor air valve part capable of changing elasticity and increasing service life and used for aluminum alloy processing

Abstract

The invention relates to the technical field of aluminum alloy processing equipment, and discloses a compressor air valve part capable of changing elasticity and increasing the service life and used for aluminum alloy processing. The compressor air valve part comprises a valve seat, wherein the lower part of the valve seat is movably connected with a valve plate; the lower part of the valve plateis fixedly connected with a movable rod; the surface of the movable rod is movably connected with a position-limiting mechanism; the back of the movable rod is movably connected with a spring rod; theposition-limiting mechanism comprises a cam; the surface of the cam is movably connected with a gas rod; and the upper part of the cam is movably connected with a retaining rod. The gas rod can be higher than the surface of the cam, and meanwhile, the cam performs the same rotational motion to drive the gas rod to be in contact with the retaining rod, so that the retaining rod can be disconnectedfrom a clamping block and stop pressing the spring rod; the movement stroke of the spring rod becomes longer, and the reciprocating contraction of the spring rod slows down so as to reduce the impactforce of the valve plate on a supporting frame during latter half movement; and therefore, the effect of controlling the elasticity of the spring and reducing the impact thereof on the supporting frame is achieved.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing equipment, in particular to a compressor air valve component for aluminum alloy processing which changes elastic force and improves service life. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. [0003] In the process of aluminum alloy processing, various equipments are needed, among which the compressor is often used as one of the auxiliary equipments. [0004] The gas valve is a component installed on the compressor cylinder to control the gas in and out, and its performance directly a...

Problems solved by technology

[0006] However, the existing air valve controls its opening and closing by the pressure difference on both sides, so the control of the spring force is very important; the spring of the air valve is too soft or due to reasons such as sticking, the valve is delayed to close, and the impact force Very large, the air valve is easily damaged

In order to improve the service life, it is necessary to increase the spring force, but it is not suitable if the spring force is too large, because ...
