The spring machine can process spring wires into various spring products. The key is to use the straightening mechanism, feeding mechanism, reducing mechanism, pitch control mechanism, and disconnecting mechanism, which are the essential structural parts. Different mechanisms serve as separate functional parts. : Straightening mechanism: The position of the straightening mechanism is between the material rack and the feeding roller. It consists of 2 sets of straightening rollers. The purpose of the straightening system software is to remove the original bending deformation of the stainless steel wire. The spring cable is calibrated After straightening, it can be stretched straight into the forming mechanical equipment, which will help the spring machine to develop the precision of the coil spring.

Feeding mechanism: It is an installation driven by the spring cable of the spring machine. It relies on two or two pairs of feeding wheels to clamp the stainless steel wire, and the transmission gear on the feeding shaft tenon of the fan-shaped worm gear is selected to feed the material. The rotation of the wheel pushes the stainless steel wire to travel in parallel. The length of the feed is the diameter of the feed wheel. The length of the spring can be determined by the number of turns of the feed wheel.
Diameter reducing mechanism: It is the operating mechanism of the spring diameter when winding the spring. The installation is composed of 2 ejector rods and the reducing cam of the driver ejector rod. When the spring machine produces variable diameter springs, such as convex and truncated cone springs, The two anchor bolts on the front, rear, left, and right of the upper jack bar are loosened, allowing the ejector rod to telescopically move back and forth in the tool table to modify the outer warp of the spring. After the ejector rod of the reducing cam driver, it reaches the destination of producing various reducing springs.

Spring machine pitch diameter changing mechanism: It is a mechanism for manipulating the spring pitch diameter. Generally, spring machine has two kinds of mechanisms. One is composed of a pitch knife and a variable cam. The variable cam is a reasonable number of operating springs, and the height-width ratio of the spring is maintained by the anchor bolts under the pitch cutter; second, the cam drive system crankshaft enables the pitch cutter to be released from the inside of the equipment, and it is stronger to estimate the large pitch spring.
Disconnecting mechanism: After winding and forming, disconnecting the stainless steel wire is a production and processing posture when the spring falls. The spring is disconnected through a knife and a core. It is a processing structure for spring processing and forming.
