Press air cushion water cooling device

Abstract

The invention discloses a press air-cushion water-cooling device. A circulating cooling water jacket is mounted outside an air cushion adjustment cavity or an air cushion locking lag oil cylinder, a pipe of a water inlet and a pipe of a water return opening are connected with the circulating cooling water jacket, a water inlet stop valve and a two-position two-way solenoid valve are mounted on the pipe of the water inlet, and a water return opening stop valve is mounted on the pipe of the water return opening. The circulating cooling water jacket is added outside the air cushion adjustment cavity, and heat in the air cushion adjustment cavity is brought away by means of circulating flow of cooling water and characteristic of large specific heat capacity of water, so that effect of air cushion cooling is achieved, and the air cushion can be operated efficiently and stably even in high-temperature regions and under the condition of high-speed production. A plurality of cooling fins are further added into the cooling water jacket of the air cushion adjustment cylinder for increasing cooling area, and a temperature sensor is added to the bottom of a cylinder body and is capable of monitoring oil temperature in real time and controlling start and stop of the device.

Description

technical field [0001] The invention relates to a cooling device in the field of mechanical engineering, in particular to an air cushion water cooling device for a press. Background technique [0002] During the use of mechanical presses, pure air cushions will generate heat and temperature rise due to the repeated flow of hydraulic oil in the adjustment cylinder in the upper and lower cylinders, especially in high-speed production lines. The traditional way to solve this problem is to increase the adjustment Increase the volume of hydraulic oil as much as possible, or add an air cooling device near the air cushion adjustment or lagging cylinder. The method of increasing the height or diameter of the adjustment cylinder or the lagging cylinder is not feasible in places where there is not enough space for installation and use, and the cooling effect is not good; the method of increasing the air cooling device near the air cushion adjustment or lagging cylinder is of great imp...
