Multi-strand coil spring continuous coil spring device

Abstract

A multi-strand spiral spring continuous spring coiling device comprises a machine frame; a spring coiling device which is used for manufacturing a steel cable roll into a plurality of strands of spiral springs and a traction push device which is used for pushing steel cables to the spring coiling device are arranged on the machine frame; the spring coiling device comprises a spring coiling supporting base which is fixedly installed on the machine frame; the spring coiling supporting base is provided with a spring winding shaft which is matched with the spring coiling supporting base in a rotary mode and a spring coiling driving mechanism which is used for driving the spring wind shaft to rotate; the periphery of the spring winding shaft is provided with a plurality of spring winding rollers which are used for limiting the steel cable and winding the cable on the spring winding shaft in a spiral mode; the spring coiling supporting base is provided with a spring winding roller radial position adjusting mechanism which is used for adjusting radial position of the spring winding shaft and a spring winding roller axial position adjusting mechanism which is used for adjusting the axial spring winding roller position of the spring winding shaft. The multi-strand spiral spring continuous spring coiling device has the advantages of satisfying the rolling machining requirement of multi-strand spiral springs and being high in production efficiency, high in machining accuracy and high in automatic degree.

Description

technical field [0001] The invention belongs to the technical field of multi-strand coil spring processing equipment, and in particular relates to a multi-strand coil spring continuous spring coiling device. Background technique [0002] Multi-strand coil spring (referred to as multi-strand coil spring) is a coil spring made of several strands of steel wire wound into a steel cable. High strength, at the same time, when the multi-strand coil spring is deformed, the mutual friction caused by the contact pressure between the strands of steel wire can absorb energy, and also has a buffering effect, and the stiffness of each strand of the multi-strand coil spring is higher than that of a single strand with the same function The coil spring is small, and its life is greatly improved under the action of dynamic load. Its service life is 3-5 times that of the traditional single-strand coil spring of the same specification. Therefore, multi-strand coil springs are widely used in v...

Problems solved by technology

One of the main disadvantages of this processing machine tool is: each section of spring processing has to go through several steps such as machine tool main body forward, steel cable clamping, spring winding, parking, machine tool main body retracting, steel cable cutting, spindle dismantling, spring dismantling, spindle clamping, etc. Steps, automatic continuous processing cannot be realized, the labor intensity is increased, the work efficiency is reduced, and the mass production of multi-strand coil springs is limited.
