Description
Technical Field
The invention relates to a double-buffering safety protection device for a press slide block, which can be widely applied to the forging process of a screw press.
Background
The existing screw press sliding block has the advantages that in the process of reciprocating linear motion of the sliding block up and down, the sliding block is fast in return stroke when rising, when the sliding block reaches the upper limit position of the sliding block, although the sliding block is prevented from impacting a machine body through a brake, the sliding block often can be strongly impacted on the machine body due to the motion inertia of the sliding block, so that the machine body can be directly damaged and cracks appear after long-term use, and the service life of the machine body is short. Especially when the brake fails or due to inertia impact, the slide block can rigidly collide with the upper beam of the machine body when moving to the upper limit position, which can seriously damage the screw press parts and even break, endangering the equipment and personal safety.

The invention aims to provide a double-buffer safety protection device for the press slide to bump against, which has double buffer protection, ensures the safe and reliable operation of the slide, protects the machine body from being damaged, and has long service life and low vibration and noise.
In order to achieve the purpose, the double-buffering safety protection device for the upper collision of the press machine sliding block comprises a machine body, a sliding block which is arranged on the machine body and can move up and down along a guide rail of the machine body, a base plate which is fixedly arranged on the periphery of the top surface of the sliding block, a double-ring-shaped rubber buffer block, a throttle valve and a machine body cross beam assembly, wherein the upper part of the double-ring-shaped rubber buffer block is in a large ring-shaped hollow shape, the lower part of the double-ring-shaped rubber buffer block is in a small ring-shaped hollow shape and is arranged on the top surface of the base plate, the throttle valve is arranged on the periphery of the top surface of the sliding block, and the machine body cross beam assembly is arranged in a cross beam hole of the machine body.
The invention relates to a double-buffering safety protection device for a press slide block, wherein a throttle valve comprises a throttle valve seat which is arranged on the periphery of the top surface of the slide block and plays the role of a spring seat, a throttle rod which is provided with a stop head inserted into the throttle valve seat and is in convex-concave embedded connection with the throttle valve seat, a throttle spring which is sleeved in the throttle rod and is arranged on the throttle valve seat, and a throttle buffering pad which is arranged at the upper part of the throttle rod, is in convex-concave embedded connection with the throttle rod, is connected with the throttle spring and is used for pressing the throttle spring.
The double-ring rubber buffer block is made of polyurethane.
The invention relates to a double-buffer safety protection device for the upper collision of a press machine sliding block, which has the working principle that: when the sliding block moves linearly up and down, the die on the sliding block is contacted with the workpiece to complete one-time striking; when the sliding block is upwards moved to return to the initial point after being struck, the high-speed return stroke and the huge inertia impact force of the sliding block can generate strong impact on the machine body, the throttle valve plays a role in load resistance and pressure buffering to reduce the load impact force, but part of the movement inertia impact force can enable the sliding block to impact the cross beam assembly of the machine body to impact the machine body, at the moment, the double-annular rubber buffer block can play a role in separation and buffer protection before the cross beam assembly of the machine body and the sliding block, double buffer protection is achieved, the sliding block is ensured to be safe and reliable in operation, the machine body is protected from being damaged, and the service life is long.
The double-ring rubber buffer block has the advantages of high elasticity, high wear resistance, high impact resistance, oil resistance, compression resistance, acid and alkali resistance, ozone resistance, aging resistance, low temperature resistance, tear resistance, strong vibration absorption force, static resistance, low noise and light weight, and is stably buffered.
The double-ring rubber buffer block is mainly used for axial vibration reduction, large bearing capacity and energy absorption and buffering. The elasticity, shock absorption, vibration reduction, buffering property and compressibility of the double-ring rubber buffer block are utilized to absorb impact force. After the external force is removed, the original shape is recovered, and the device can be repeatedly used.
According to the double-buffering safety protection device for the press sliding block, the upper part of the double-annular rubber buffer block is in a large annular hollow shape, the lower part of the double-annular rubber buffer block is in a small annular hollow shape, and in the process of pressing the double-annular rubber buffer block, the compression space is increased, and the buffering capacity is high.
According to the double-buffering safety protection device for the press machine sliding block, the double-annular rubber buffer block absorbs energy through the collision of the double-annular rubber buffer block by utilizing the shock absorption, vibration reduction and buffering characteristics of rubber materials, so that the sliding block is prevented from being in rigid impact with the upper cross beam of the machine body, the buffering protection effect is achieved, the accidental damage to equipment due to the overlarge impact force of the sliding block is avoided, and the service life of the equipment is prolonged. Meanwhile, the vibration and the noise are small.
In conclusion, the double-buffering safety protection device for the press slide block disclosed by the invention has the advantages of double buffering protection, safety and reliability in operation of the slide block, damage prevention of the machine body, long service life and low vibration and noise.
