Cooling device of hydraulic red punching equipment and cooling method thereof

Abstract

The invention relates to a cooling device of hydraulic red punching equipment. The cooling device comprises a spray liquid storage barrel, a first nozzle and a second nozzle, wherein the first nozzleis connected with the spray liquid storage barrel, the second nozzle is connected with the spray liquid storage barrel, and the first nozzle and the second nozzle are sequentially arranged on the leftside and the right side of a fixed long shaft; the first nozzle is corresponding to a punching head of the hydraulic red punching equipment, and is used for cooling the punching head through spray; and the second nozzle is corresponding to a die cylinder, and is used for cooling a workpiece formed by punching through the spray. According to the cooling device, a control device is arranged to reasonably adjust the compressed air pressure and the cooling water flow of each of the atomizing nozzles, and therefore the optimal atomization effect can be achieved, and the workpiece can be uniformlycooled; and the relative position of the first nozzle and the second nozzle are adjusted, the distance between the atomizing nozzles is reasonably selected, and therefore the water amount of a coolingsurface of the workpiece can be uniform, and the water is atomized and sprayed under the action of the compressed air jet flow so as to cool the workpiece.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a cooling device and a cooling method for hydraulic red punching equipment. Background technique [0002] With the advancement of society and the development of science and technology, the machinery industry has put forward new requirements for the mechanical strength of mechanical parts. To improve the mechanical strength of mechanical parts, two methods are generally used. One is to change the material of the parts, and the other is to change them. processing method. The red punching process used in the red punching furnace is one of the effective methods to improve the mechanical properties of parts by changing the processing method. It is actually a hot extrusion process, which has a good development prospect and has been widely used. [0003] The specific processing method of the red punching process is to heat the brass rod or iron rod until it is ...

AI Technical Summary

Problems solved by technology

In the cooling device of the above-mentioned oil cooling method, the cooling efficiency is excellent, but there is a problem that it is almost impossible to perform fine cooling control, and the heat-treated product is easily deformed.

On the other hand, in the cooling device of the gas cooling method, the cooling control is easy by means of the flow control of the gas, etc., and the performance is excellent in the deformation of the heat-treated product, but there is a problem of low cooling efficiency.
