Wire feeding wheel cover plate device for suspension spring production

Abstract

The wire feeding wheel cover plate device for suspension spring production comprises a spring steel wire, a plurality of wire feeding wheels and spring equipment, the spring steel wire is fixedly installed in wire grooves of the wire feeding wheels, the wire feeding wheels are installed on the spring equipment, the spring equipment is provided with a guide assembly, the wire feeding wheels are provided with pressing and fixing assemblies, and the pressing and fixing assemblies are fixedly connected with the spring steel wire. The spring equipment is provided with a machining forming assembly, the spring equipment is provided with a buffering assembly, and the pressing and fixing assembly comprises a cover plate, a first bolt, a first bolt hole, a third bolt, a third bolt hole and a wire feeding shaft. Loosening of the control bolt causes loosening of the wire feeding wheel; severe abrasion of a wire feeding wheel and a wire feeding shaft is avoided; the geometric dimension of the spring is stabilized; the repair and maintenance time is shortened, and the production efficiency is improved; the service lives of the bolt, the wire feeding wheel and the wire feeding shaft are prolonged, the production cost is reduced, and the labor efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of spring production, in particular to a wire feeding wheel cover device for suspension spring production. Background technique [0002] The production of cold rolled spring is to install the spring steel wire on the spring coiling machine, provide the driving force through the feeding system, position the wire feeding wheel and the middle guide plate to guide the conveying direction of the steel wire, and finally control the outer diameter of the spring through the stopper wheel and control the pitch knife The pitch of each coil of the spring, after forming the spring shape, the cutting knife cuts off the material with the cooperation of the mandrel knife to form the spring. The whole process is completed through the compiled program. [0003] The production process of the coil spring is relatively mature. In the actual operation process, since the principle of feeding the steel wire by the wire feeding whe...

AI Technical Summary

Problems solved by technology

The wire feeding wheel is installed on the wire feeding shaft. The inner hole of the wire feeding wheel and the outer diameter of the wire feeding shaft are in clearance fit. The two wire feeding wheels are under reverse force during the rotation process. The force is all transferred to the six wire feeding wheels to fix the wire feeding wheel. It is connected to the bolt on the wire feeding shaft. At the same time, during the production process of the spring coiling machine, especially when cutting and blanking, the vibration is relatively large. Long-term equipment operation will cause the wire feeding wheel fastening bolt to become loose.

After the fastening bolts of the wire feeding wheel are loosened, the frequency of fastening the bolts of the coil spring workers will be increased. The loosening of the bolts will double the axial shear force on the bolts, resulting in an increase in the frequency of bolt breakage, damage to the screw holes of the wire feeding shaft, and loosening of the bolts. It will also lead to the loosening of the wire feeding wheel. Continued production after the wire feeding wheel is loose will accelerate the wear of the wire feeding wheel and the wire feeding shaft, and the unsteady feeding of the spring coiler will cause fluctuations in the geometric dimensions of the spring. In severe cases, it will cause equipment damage and frequent adjustment of the fastening bolts. And replacement, not only seriously affects the production efficiency, but also the continuous stability of the product is poor, which greatly increases the production cost, so we design a wire feeding wheel cover device for suspension spring production
