Description

Technical Field

[0001] The utility model relates to the technical field of spring manufacturing, in particular to a stamping and knurling integrated machine for spring manufacturing. Background Art

[0002] A spring is a mechanical component that utilizes elasticity to function. Parts made of elastic material deform under external forces and return to their original shape when the force is removed. They are typically made from spring steel. Existing processing procedures include stamping and knurling spring steel, a process that requires a stamping and knurling machine.

[0003] The National Patent Network discloses a stamping and knurling integrated machine for spring manufacturing, with the patent publication number "CN220462911U". It mainly arranges a driving gear driven by a first driving motor to rotate, and arranges a driven rack symmetrically distributed on the center to drive the embossing roller installed through the guide block to lift and lower, so as to facilitate the tight embossing treatment of the spring steel; a rotating shaft that can be raised and lowered synchronously is arranged through the embossing roller, and a transmission belt is connected between the embossing roller and the rotating shaft, and an air cylinder corresponding to the embossing roller is arranged by the rotating shaft to blow the dust on the embossing roller, and a dust collection box equipped with a suction pump is used to enhance the dust removal treatment.

[0004] However, during use, the two embossing rollers are driven up and down mainly by the meshing between the gear and the rack. During long-term use, the gear and the rack will wear out, resulting in poor meshing effect, which will cause gaps in the embossing rollers during the embossing process, affecting the knurling effect. Moreover, the tooth pitch between the gear and the rack can only be adjusted according to the tooth pitch, and the embossing effect on different springs is different and poor. Moreover, the wear of the gear during long-term use will cause the transmission rod effect to deteriorate, affecting the normal use of the embossing device. Based on the above problems, the utility model proposes a new stamping and knurling integrated machine for spring manufacturing. Utility Model Content
