Self-pressurizing bidirectional balancing buffer device for press machine

Abstract

The invention provides a self-pressurizing bidirectional balancing buffer device for a press machine and relates to a self-pressurizing balancing buffer device for balancing motion inertia of a sliding block on a large-size quick press machine. The self-pressurizing bidirectional balancing buffer device comprises a balancing cylinder and an air storage cylinder, wherein a free end of a piston rod of the balancing cylinder is connected with the sliding block of the corresponding press machine; air holes are respectively arranged on end covers at two ends of the balancing cylinder; an air outlet of the air storage cylinder is respectively communicated with the air holes at the two ends of the balancing cylinder through air pipes; and solenoid valves are respectively arranged on the air pipes communicated with a rod cavity and a rod-less cavity of the balancing cylinder. The self-pressurizing bidirectional balancing buffer device for the press machine has the advantages that the motion impact and the inertia impact of the sliding block of the press machine are reduced; the vibration is relieved and the noise is reduced; the manual operation environment is improved; the service life of the press machine and mould is effectively prolonged; and a self-pressurizing device is used for controlling and adjusting the pressure air, so that the normal running of a bidirectional balancing device is ensured.

Description

technical field [0001] The invention relates to a self-pressurized balance buffer device for balancing the motion inertia of the slider on a large-scale fast press, and can realize two-way balance and buffer at the same time, so as to adapt to the rapid working process of the press due to the increase or decrease of the slider acceleration. The resulting inertial impact belongs to the field of forging equipment and manufacturing technology with a high degree of automation. Background technique [0002] With the rapid development of the modern machinery industry, the press as a forging equipment is also constantly moving towards the direction of automation, precision, intelligence, high speed and high efficiency. While realizing automation and reducing the labor intensity of workers, it is more necessary to avoid the harm caused by strong vibration, impact and noise pollution during equipment operation. The function of the traditional press balance device is only to prevent ...

Problems solved by technology

The function of the traditional press balance device is only to prevent the weight of the slider from accelerating the moving part when the slider moves downward, causing "leading" and causing the transmission part to hit. This balance method has little effect on inertial impact and balance, so it is generally It is only suitable for the motion balance of small and medium-sized low-speed presses, but it is obviously not suitable for large-scale fast presses

During the operation of a large fast press, the kinematic characteristics of the crank-link mechanism cause periodic changes in the acceleration of the slider movement, and the inertial force caused by the acceleration also changes periodically. For large fast presses , the inertial force caused by this acceleration can no longer be ignored, especially on multi-link presses with snap-back characteristics, the peak value of acceleration increases more significantly, resulting in greater noise and vibration during the operation of the equipment.
