Description

Technical Field

[0001] The present application relates to the technical field of spring production, and in particular to a variable diameter assembly for producing variable diameter springs. Background Art

[0002] A variable diameter spring is a special type of spring characterized by different diameters in different parts of the spring. The manufacturing process of a variable diameter spring is relatively complex, and a spring machine is a type of machine equipment that has gradually developed with the emergence of various springs and is used to produce and manufacture springs.

[0003] A Chinese patent discloses an automated spring machine for producing variable diameter springs, with authorization publication number CN212419431U. The patent involves a support, a steel wire, a wire feeding mechanism mounted on the support, a forming unit, and a cutter. The forming unit and cutter are driven by a drive mechanism. The forming unit includes a limit block, a positioning block, a push block, and a fixed block. The steel wire is fed horizontally from the wire feeding mechanism, guided by the limit block, and then bent by the positioning block to form an arc around the outer periphery of the fixed block. The limit block and the positioning block form an obtuse angle between them. The push block is located on the inner side of the steel wire. The automated spring machine for producing variable diameter springs, while modifying the forming unit to coordinate the limit block, positioning block, push block, and fixed block, completes the winding of the steel wire under the stable push of the driving member. Furthermore, the diameter of each coil of the spring can be flexibly changed as needed during the forming of the steel wire. This improves the processing efficiency of the formed springs, thereby making the device more applicable. However, the arcuate grooves of the limit blocks and positioning blocks provided in the above-mentioned spring machine have a fixed width. When the spring machine processes spring wires of different diameters, the fixed-width arcuate grooves may not work well with spring wires of different diameters, which may lead to instability during the spring wire processing or cause the spring wire to fall out of the arcuate grooves during coiling, resulting in unstable use. Therefore, those skilled in the art have provided a reducing assembly for producing reducing springs to address the problems raised in the above-mentioned background art. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a variable diameter assembly for producing variable diameter springs, which solves the problems mentioned in the above background technology.

[0006] (2) Technical solution

[0007] To achieve the above objectives, the present application is implemented through the following technical solutions: a reducing assembly for producing reducing springs, comprising a mounting plate, a movable plate being slidably connected to the interior of the mounting plate, a C-shaped support frame being fixedly connected to one end of the movable plate located outside the mounting plate, a reducing assembly connected to the movable plate being provided inside the mounting plate, the reducing assembly being used to adjust the position of the support frame, and a positioning assembly being provided inside the support frame;

The rotating worm can better drive the worm wheel to rotate to realize the rotation operation of the turntable. The horizontal movement operation of the movable plate can be realized through the action of the rotating turntable and the connecting rod set at the eccentric position of the turntable.
