Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a spring steel cutting machine for a wave spring processing line. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external forces and return to their original shape after the external force is removed. There are many types of springs, which can be divided into disc springs, annular springs, wave springs, leaf springs, spiral springs, truncated cone scroll springs, torsion bar springs, etc. according to their shapes. According to the nature of the force, springs can be divided into tension springs, compression springs, torsion springs, and bending springs. Springs are generally made of spring steel. Before the spring steel is wound into springs, it needs to be cut into steel materials of the same length using a cutting device to facilitate the subsequent spring processing and winding work.

[0003] The patent with application number CN202122694685.2 discloses a cutting device for spring processing, which is provided with a bottom plate, a vertical plate, a top plate, a lower clamping plate, a lower clamping groove, an upper clamping groove, a second bevel gear, a forward and reverse motor, a limit slider, a limit slide groove, a chain saw and other structures. Multiple spring steels are clamped by two sets of upper and lower clamping plates, and the motor drives the lead screw to rotate and drive the chain saw to move, so that multiple spring steels can be cut at one time. Although the clamping and cutting structures are provided to achieve a single cutting of multiple spring steels, there is no structure for adjusting the position of the spring steel. After a cutting operation is completed, the position of the spring steel needs to be manually adjusted to achieve subsequent cutting operations. The operation is cumbersome and still has certain limitations. For this reason, we propose a spring steel cutting machine for a wave spring processing line to solve the above problems.
