A cooling system for punch presses

Abstract

The invention relates to a cooling system used for a punching machine. The cooling system comprises a machine frame, slide blocks, a hot oil recycling box, a hot oil cooling device and at least one slide block guide rod. Slide block oil inlets are formed in the upper surfaces of the slide blocks. Slide block oil outlets are formed in the side faces of the slide blocks. Slide block oil ways are arranged in the slide blocks. A slide block guide rod oil inlet and a slide block guide rod oil outlet are formed in the two ends of each slide block guide rod. A slide block guide rod oil way is arranged in each slide block guide rod. The slide block guide rod oil outlets communicate with the hot oil recycling box. The hot oil recycling box communicates with a hot oil inlet of the hot oil cooling device. A cold oil outlet of the hot oil cooling device communicates with the slide block oil inlets. The slide block oil outlets communicate with the slide block guide rod oil inlets. By means of the cooling system, the temperature of the slide blocks can be lowered in the continuous punching process, expanding or deforming of the slide blocks is avoided, the punching machine can keep good punching precision, the service life of the slide blocks is prolonged, the shutdown maintenance time is shortened, and the use cost of the punching machine is reduced.

Description

technical field [0001] The invention relates to the technical field of punch presses, in particular to a cooling system for punch presses. Background technique [0002] A punch press is a device used to stamp sheets. [0003] The existing punching machine is not provided with a slider cooling device or is not provided with a forced cooling system on the slider. In the process of continuous stamping, the mold generates a lot of heat energy due to friction and extrusion of the processed workpiece, which is transmitted to the slider, making the slider in a high temperature state for a long time during work, and the high temperature will cause the slider to expand. In severe cases It will even deform the slider, thereby reducing the movement gap of the slider and reducing the machining accuracy of the punching machine. In severe cases, the machine will be locked or the slide rail will be damaged, which will reduce the service life of the slider and increase the cost of downtime...

In the process of continuous stamping, the mold generates a lot of heat energy due to friction and extrusion of the processed workpiece, which is transmitted to the slider, making the slider in a high temperature state for a long time during work, and the high temperature will cause the slider to expand. In severe cases It will even deform the slider, thereby reducing the movement gap of the slider and reducing the machining accuracy of the punching machine. In severe cases, the machine will be locked or the slide rail will be damaged, which will reduce the service life of the slider and increase the cost of downtime maintenance.
