Abstract

The invention belongs to the field of metal wire forming equipment, and particularly relates to a screw pitch control mechanism of a spring machine. The screw pitch control mechanism of the spring machine comprises a machine frame. A drive part is arranged on the machine frame, first level push rods are arranged on a first level push plate, the first level push plate is connected with the drive part, the first level push rods are connected with a second level push plate, a second level push rod is arranged on the second level push plate, a third level push plate is connected with the second level push rod, and third level push rods are arranged on the third level push plate. The screw pitch control mechanism of the spring machine has the advantages that due to the guiding of guide posts and the even driving force of an oil cylinder, deviation is eliminated to a maximum limit, and the normal control over the screw pitch of the spring machine is guaranteed.

Description

technical field [0001] The invention belongs to the field of metal wire forming equipment, in particular to a pitch adjusting mechanism of a spring machine. Background technique [0002] The existing spring machine includes a wire feeding transmission device, a straightening device, a wire forming device and a cutting device. The device is used for bending and winding the processed metal wire, and the cutting mechanism is used for cutting the preliminarily formed spring into finished products. The thread forming device of the existing spring machine needs to push the thread pitch of the coiled wire. When pushing the thread pitch, a horizontal thrust should be given in the opposite direction along the axis of the spring, and the two front push rods arranged up and down are applied. The thrust must be moderate in size and precise in direction to meet the needs of actual production and processing. However, in the existing push pitch mechanism, when one of the front push rods ...
