Description

Technical Field

[0001] The utility model belongs to the technical field of spring processing equipment, in particular to a fixing device for spring cutting processing. 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 force and return to their original shape after the external force is removed. They are generally made of spring steel. There are many types of springs. According to their shapes, there are mainly coil springs, scroll springs, leaf springs and special-shaped springs. During the production and processing of springs, the straight strips of spring steel materials need to be cut. At this time, a fixture for spring cutting is required.

[0003] After searching, the patent announcement number CN211491047U discloses a spring processing fixture, including a bottom plate, two support plates are fixedly installed on the top of the bottom plate, a carrier plate is fixedly installed between the two support plates, a drive motor is fixedly installed on the top of the carrier plate, the output shaft of the drive motor is fixedly connected with a threaded rod, the outer side of the threaded rod is threadedly connected with a threaded tube, a slide bar is fixedly installed on the left side of the threaded tube, a limit block is fixedly installed on the left end of the slide bar, the limit block is slidably connected inside the slide rail, and the left side of the slide rail is fixedly connected with a first fixed rod. In the spring processing fixture, the rubber pad can play a role of shock absorption and protection, preventing the clamping block and the fixing block from damaging the surface of the processed spring, reducing the error caused by machine vibration, reducing the appearance of defective products, reducing production costs, preventing the processed spring from compression and deformation, and facilitating workers to clean up.

[0004] In actual use, the existing spring cutting and processing fixing device generally only fixes and clamps the straight strip spring steel material in one direction. When the cutting structure cuts the straight strip spring steel material, the straight strip spring steel material will have a certain deviation, affecting the cutting accuracy of the straight strip spring steel material. For this reason, we propose a spring cutting and processing fixing device to solve the existing problem. Utility Model Content
