What is the function of the main structural part of the wire spring machine?

Straightening structure: The position of the straightening mechanism is between the feed frame and the feed roller. It consists of two sets of straightening rollers. The purpose of the straightening system is to eliminate the original bending deformation of the steel wire. The spring wire can be straightened after straightening. Into the forming machinery, which is conducive to the wire spring machine to improve the accuracy of the coil spring.

Feeding structure: This is a device for conveying spring wire propelled by a wire-turning spring machine. It is a pair of or two pairs of feeding wheels to press the steel wire. It is completed by a fan-shaped incomplete gear driving the gear on the feeding wheel shaft to be driven by the rotation of the feeding wheel The wire goes straight, the feed length is the circumference of the feed wheel, and the length of the spring can be determined by the number of rotations of the feed wheel.

Reducing structure: It is the control mechanism of the outer diameter of the spring when winding the spring. The device is composed of two ejector rods and a reducing cam that drives the ejector rod. When the rotary spring machine produces the reducing spring, such as convex, truncated cone The two bolts on the front and back of the spring and the upper jack are loosened to allow the jack to telescope back and forth in the tool holder to change the outer diameter of the spring. The jack is driven by the reducing cam to achieve the purpose of producing various reducing springs.

Pitch change structure: It is a mechanism to control the spring pitch. Usually, there are two kinds of structure of the wire-turning spring machine. One is composed of a pitch knife and a variable-angle cam. The variable cam is to control the effective number of turns of the spring, and the bolt under the pitch knife adjusts the height of the spring; the second is to drive the connecting rod by the cam, so that the pitch knife is pushed out of the machine, and the spring with a large pitch is better estimated.

Cutting structure: After winding and forming, cutting the steel wire is the last processing action of the spring falling. When the spring is cut, it is completed by the knife and the core. This is the processing structure of the final forming of the spring processing.
