Abstract

The invention discloses a torsional spring cut-off bevelment method and device. Two cutters are arranged on a fixed end plate of a torsional spring winding machine and fixed on two movable racks correspondingly, each movable rack is connected with a fixed guiding rack in a sliding manner, the movable racks perform regular movement back and forth through cranks and model blocks, and after winding forming of a torsional spring, the two cutters form bevelment under the state of completely breaking away from a mandrel to cut off the formed torsional spring; or a cutter and a cushion block are arranged on the fixed end plate of the torsional spring winding machine and fixed on the two movable racks correspondingly, each movable rack is connected with one of the fixed guiding racks in a sliding manner, the movable racks perform regular movement back and forth through the cranks and the model blocks, and after winding forming of the torsional spring, the cutter and the cushion block form bevelment under the state of completely breaking away from the mandrel to cut off the formed torsional spring. Impact on the mandrel is prevented, deburring is convenient and quick, and the probability of production deformation is low.

Description

[0001] Technical field: [0002] The invention relates to a torsion spring production equipment, in particular to a method and device for cutting and halving a torsion spring. [0003] Background technique: [0004] At present, the production of torsion springs is completed by winding, shaping, and cutting by torsion spring winding machines. Align the torsion spring with the bottom, cut off the end of the torsion spring on the mandrel, and then form the finished torsion spring. Due to continuous operation, the cutting knife continuously impacts the mandrel, causing damage to the mandrel, which not only affects the cutting effect, but also causes the mandrel to be scrapped, and the mandrel is frequently replaced, which increases the production cost. [0005] Invention content: [0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a torsion spring cutting and halving method and device with reasonable d...
