Quick workpiece cooling device for hardware processing

Abstract

The invention discloses a quick workpiece cooling device for hardware processing and belongs to the technical field of hardware processing. For workpieces of different shapes, comprehensive multi-point setting on the workpiece is carried out first by means of a magnetic driven telescopic structure, and meanwhile, liquid state water after hydraulic change is cooled to be frozen, so that on the onehand, the telescopic structure is locked and positioned, and a local deformation phenomenon of the workpiece in the cooling process is avoided, and on the other hand, an air flow for cooling is cooled, the cooled air flow is diffused at a contact end of the telescopic structure to blow the surface of the workpiece, cooling dead angles are not prone to happen, multi-point distributed cooling is formed, and the workpiece can be quickly cooled comprehensively and uniformly by matching with a quick heat conducting property of the contact end. The processing property is improved, internal stress ofa material is removed, the dimension of the workpiece is stabilized to prevent deformation and cracking, and the forming quality and the dimensional precision of the workpiece are improved obviously.

Problems solved by technology

[0003] In the metal processing process, due to the high temperature generated during drilling, polishing, grinding and other processes, the workpiece needs to be cooled, which not only facilitates the continuation of the subsequent process, but also facilitates the shaping of the workpiece to force the internal structure to stabilize, improve processing performance, and remove The internal stress of the material stabilizes the size of the workpiece, prevents deformation and cracking, and is conducive to improving the molding quality of the workpiece. At present, the most common cooling methods in the hardware processing process are water cooling and air cooling. Water cooling has a good cooling effect and high cooling efficiency, but The equipment installation is more expensive and cumbersome, and the water cooling method is more severe, but it is easy to cause a series of quality problems such as internal cracking, hardness reduction, and obvious deformation of the workpiece due to rapid temperature changes. Although the cooling effect of air cooling is worse than water cooling, the equipment The installation cost is low, and the cooling effect is relatively mild, which is conducive to the gradient cooling of the workpiece and the improvement of the forming quality of the workpiece, so the latter is widely used in the cooling of the workpiece

[0004] However, most of the existing air-cooled workpiece cooling devices use a blower to convectively blow to the workpiece, and there is generally a phenomenon of uneven cooling. The cooling on both sides is faster, while the central area and dead corner areas are difficult to blow to, resulting in slower cooling. The overall quality of the workpiece The difference in cooling has a great influence on the strength and size of the workpiece. Due to the effect of thermal expansion and contraction, local deformation of the workpiece often occurs, especially for workpieces with irregular shapes and high precision requirements. It is difficult for the existing cooling device to achieve high efficiency. While cooling, the molding quality and high-precision dimensional requirements of the workpiece are guaranteed
