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...

Problems solved by technology

[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, hydraulic system and grinding device, resulting in The liquid cooling system and the hydraulic system need more connecting pipes and spring grinders to connect the cooling equipment and hydraulic equipment, which increases the space occupation of the production site and also increases the investment cost, because the liquid cooling system, hydraulic system and grinding device are all If it is exposed on the production site, without taking protective measures, it is vulnerable to dust and other substances, resulting in unstable operation of the equipment

[0004] In the process of grinding the spring, the temperature of the grinding surface of the spring will continue to rise, which will cause the grinding surface of the spring to be burned and the spring to soften. In order to reduce the temperature of the spring during the grinding process, liquid is used in the prior art The method of circulating cooling is used to reduce the temperature, but the abrasive debris generated by the spring during the grinding process will also flow into the coolant storage tank with the coolant, causing the abrasive debris to accumulate in the coolant storage tank. Since the coolant storage tank is sealed, It is very difficult to remove the grinding debris, and at the same time, the circulating cooling device will also inhale a large amount of grinding debris during operation, causing blockage of the circulating cooling device and damage to parts

[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
