Description
Technical field
The present invention relates to torsion spring processing technique field, more particularly to a kind of extraordinary duplex torsion spring manufacture method and mould.
Background technology
At present, the processing method for producing duplex torsion spring with engine lathe is first to process left-handed torsion spring bullet with coiling plug respectively
Spring and dextrorotation torsionspring, are then connected as a duplex torsion spring by way of welding by left and right torsion spring again.
The problem of current this processing method has following：(1) waste of raw materials is more, and welding difficulty is big.Due to being point
Open that coiling is left-handed and dextrorotation, many clouts can be stayed in manufacturing process, while as the spring steel more than alloying element content in weldering
Be easily formed in termination process be mingled with, the defect such as crackle.(2) spring performance is reduced.The tensile strength of part material is less than after welding
The tensile strength of mother metal, reduces the mechanical performance of spring.(3) processing efficiency is low.The manufacturing procedure of spring is more, the process-cycle
It is long.(4) machining accuracy is low.Because left-handed spring and dextrorotation spring are independent coilings, therefore its external diameter and stress have differences,
Cause the coaxiality error between the left-right rotary of same spring big.Welding often leads to two to Assurance of Size ability simultaneously
Spacing tolerance between angle can not ensure drawing requirement.
The content of the invention
The technical problem of the invention mainly solved in the presence of prior art, so as to provide a kind of saving raw material, add
Work process is few, the cycle is short and the stable extraordinary duplex torsion spring manufacture method of crudy and mould.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
The extraordinary duplex torsion spring manufacture method that the present invention is provided, it comprises the following steps：
S1, by coiling plug be arranged on lathe on, around the sidespin end for making duplex torsion spring；
S2, the coiling plug is arranged on bending die, to the progress profiling coiling of middle the journal stirrup of the duplex torsion spring；
S3, the coiling for carrying out another sidespin end of duplex torsion spring.
Further, step is also included after the step S3：
S4, to the duplex torsion spring carry out stress relaxation；
S5, the making to the number of active coils and journal stirrup of the duplex torsion spring, while repairing each shelves chi of the duplex torsion spring
It is very little；
S6, the duplex torsion spring trimmed is identified.
Further, step is also included after the step S2：
S21, another sidespin end of the duplex torsion spring carry out the fixation of the journal stirrup side with limited block.
The present invention also announces a kind of extraordinary duplex torsion spring manufacture mould, including bending die and coiling plug, the bending die
Including bending mould body and journal stirrup type block, the journal stirrup type block is fixed on the middle position of the bending mould body, described curved
Bent mould body bottom is provided with a groove, and the coiling plug is arranged in the groove.
Further, the coiling plug and the bending mould body detachable connection.
Further, limited block is additionally provided with the bending mould body, the limited block is located at the one of the journal stirrup type block
Side.
The beneficial effects of the present invention are：The molding mode of duplex torsion spring is one-shot forming, eliminates welding sequence, simultaneously
Cost has been saved, the service life of duplex torsion spring is improved, also, contoured design is introduced in the design of mould, has not only been carried
The production efficiency of high duplex torsion spring, and improve the machining accuracy of duplex torsion spring.
