Cushion cylinder device

Abstract

The invention relates to a novel cushion cylinder device, in particular to a technical field of cushion cylinder, which is vertically arranged and connects the bearing element and the striking element, comprising a cylinder, a piston and a piston rod, wherein a discharge valve is arranged on the top of the cylinder, the bottom end-face faces the bearing element, the piston is provided with a central hole, the piston rod traverses the central hole and can axially move in the piston, top of the piston rod passes the cylinder end-face and is connected with the cylinder, bottom of the piston rod is connected with the striking element. The invention makes the piston rod traverse the piston and be connected with the cylinder, to make the cylinder move respectively to the piston, when the piston touches the bearing element, the striking element drives the cylinder to move downward and the compressed air in the cylinder can be discharged via a noise-reduction baffler to slow down the velocity of the relative movement to realize the cushion, the design combined with the noise-reduction cavity can make the noise during the cushion of cylinder lower. The invention is applicable to cushion generated during the heavy-load impact element strikes the bearing element at high speed, in particular to the cold area.

Description

technical field

[0001] The invention relates to a cylinder, in particular to the technical field of a buffer cylinder. Background technique

[0002] Objects moving at high speed will collide with the joint surface when they reach the target stroke. In the past, people installed elastic materials on the contact surface of two objects, such as rubber, sponge, etc., to protect the object and prevent the object from being damaged by impact. The advantage of this is low cost, but the disadvantage is short life and poor reliability. On some large-mass, high-speed moving objects, such a buffering method is obviously not applicable; therefore, people use hydraulic and pneumatic buffering devices to achieve buffering, and a device with a buffering function is used to achieve buffering at a position close to the target. This device can When approaching the target position, decelerate until it stops smoothly, but the maintenance period of the hydraulic device is short, and the cost of...
