Description

【Technical field】 [0001] The invention relates to the technical field of spring grinding machines, in particular to the technical field of spring grinding machines. 【Background technique】 [0002] Generally, due to the shape of the spring, the two ends of the spring will be slightly raised and there will be more uneven material. However, some spring applications require the two ends of the spring to be relatively flat, so that the two ends of the spring and The contact area between the placement surfaces increases, thereby promoting the stability of the positioning, that is, the so-called straight angle of the end face needs to be relatively flat, so a spring grinder must be used to grind and smooth both ends of the spring. [0003] In the prior art, the supporting liquid cooling system, hydraulic system and grinding device on the spring grinding machine are all separately placed on the production site, which creates a certain distance between the liquid cooling system, hydr...

AI Technical Summary

Problems solved by technology

[0005] In order to reduce the temperature of the spring during the grinding process, liquid circulation is generally used for cooling. Due to the spring grinding process in the prior art, one is that the spring fixing seat remains in the original position, and the grinding machine moves forward for grinding. The spring fixed seat moves forward, and the grinding machine keeps the original position for grinding. In these two methods, the end face and the grinding wheel of the spring grinding are kept in the grinding state during the whole grinding process from the spring grinding to the predetermined grinding length of the spring. There is no cooling time, especially for springs made of spring steel with a larger diameter, it takes longer in the grinding process, and the temperature of the grinding surface will be higher, so that the temperature of the spring will continue to rise during the grinding process, a single The use of liquid circulation cooling can not achieve a good cooling effect
