Problems solved by technology

In the existing technology, in order to improve the tempering efficiency, parts are often tempered in large quantities, and a large number of parts are accumulated in the tempering frame, which is easy to cause a large amount of heat to accumulate at the bottom of the tempering frame, making the parts at the bottom of the temperature higher , and the temperature of the parts located on the surface is relatively low, so parts of the same batch are prone to uneven tempering quality, and the qualified rate is low

Abstract

The invention discloses a tempering air ventilating cylinder. The tempering air ventilating cylinder comprises a cylinder body, wherein the cylinder body is used for containing a plurality of to-be-treated parts; a plurality of through holes are uniformly formed in the surface of the cylinder body in the circumferential direction. The tempering air ventilating cylinder has the advantage that whenthe multiple parts from the same batch are tempered, the parts can be paved on the surface of the cylinder body; because the through holes are uniformly formed in the surface of the cylinder body in the circumferential direction, when the tempering heat treatment is performed, the hot air flow can simultaneously flow into the cylinder body via the through holes in the surface of the cylinder body,and then can heat the parts in the cylinder body, so that the temperature uniformity of each position in the cylinder body is guaranteed, thereby improving the tempering uniformity of each part in the cylinder body, ensuring the sufficient tempering of each part, and improving the quality and qualified rate of each part.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a tempering ventilation cylinder. Background technique [0002] With the development of China's machinery industry, more and more machining processes have been widely used in various production lines. [0003] Mechanical processing mainly includes manual processing and numerical control processing. Manual processing refers to the method of processing various materials through the manual operation of mechanical equipment such as milling machines, lathes, drilling machines and sawing machines. Manual processing is suitable for small batches, Simple part production. CNC machining (CNC, Computer numerical control) refers to the use of numerical control equipment by mechanical workers for processing. These CNC equipment include machining centers, turning and milling centers, wire electric discharge equipment, thread cutting machines, etc. The vast majority of machining worksh...
