Description
Technical field
The utility model relates to a kind of torsional spring torque arm transition arc molding machines, for torsional spring torque arm transition arc position
Assistant formation belongs to torsional spring forming auxiliary device field.
Background technique
Because torsional spring is in working condition, the stress of torque arm transition arc position is maximum, therefore is easiest to cause here
Whether fracture, so to pay close attention to surface quality herein in process of production, is not allow for obvious impression, and have herein bright
Aobvious impression and molding machine have very direct relationship.
The transition arc of conventional torsional spring torque arm is to be process by top with the forming frock of evagination circular arc, is being processed
In the process, the evagination circular arc positioned at top is contacted with torsional spring material (steel wire), and by cooperating with the tooling of another pushing to torsion
Spring carries out bending, so that the torque arm bending part of torsional spring forms the arc transition of corresponding size, it follows that evagination circular arc is molding
Stress maximum, most easily worn position in tooling, and in order to avoid interference, the marginal position of evagination circular arc can only be used to form,
Meanwhile platform and bottom bracing structure of the forming frock used at present all by top with evagination circular arc form and entirety is adopted
It is made of integral forming process, i.e., the forming frock is disposable, therefore, can only be right after the edge of outer dome arc is impaired
Forming frock is replaced, and can not be reused, and otherwise be will cause the bending angle variation of torsional spring torque arm transition arc or is made
Occurs impression on torsional spring, to influence the quality of produced torsional spring.And in actual processing production process, the forming frock
Replacement frequency it is very high, maintenance of equipment maintenance cost is big.
