Abstract
the invention discloses a forming process for processing stainless steel round wire materials into special-shaped wire materials, which comprises the steps of firstly processing one or more circles of forming grooves on the surface of a cylindrical roller, and then clamping the processed cylindrical roller on a three-jaw chuck of a lathe; at this moment, install the tool bit that the band pulley rolled on the blade holder of lathe to make the round roller hug closely cylindrical roller surface after aiming at the shaping groove, then go into the shaping inslot with the circular silk material card of stainless steel, the rethread lathe slowly drives cylindrical roller and rotates, like this alright roll the circular silk material of whole circle stainless steel in with the shaping inslot in succession the dysmorphism silk material of different cross sectional shapes through the gyro wheel. The invention can process the stainless steel round wire into materials with different section sizes and shapes by adopting the existing lathe, replaces the processing mode of the existing cold punching die, and has the advantages of convenient operation, low manufacturing cost and high working efficiency.
Description
Technical Field
The invention relates to a forming process for processing stainless steel round wires into special-shaped wires, belonging to the technical field of cold processing.
Background
the shape of the clip on the replaceable double-lug supporting plate self-locking nut is complex, the clip not only requires certain hardness but also requires certain elasticity due to the requirement of replaceability, and the raw material of the clip is 0Cr18Ni9 stainless steel round wire which is a non-heat-treatable reinforced material, and the strength and hardness of the material are improved only through cold deformation. The shape of the clip is as shown in fig. 2 and fig. 3, the cross section of the clip is rectangular, according to the conventional stamping processing mode, the round wire needs to be cut into small sections, and then the round wire is stamped into the material with the rectangular cross section by the forming die, however, the efficiency of forming the material by the die is very low, each set of die can only form the material with one cross section, when the materials with different sizes and different cross sections are needed, more dies need to be added, and the production cost is increased.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides the forming process for processing the stainless steel round wire into the special-shaped wire, which has the advantages of simple processing, good forming quality and cost saving, and overcomes the defects in the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme: a shaping process for processing stainless steel round wire into special-shaped wire comprises the steps of firstly processing one or more circles of shaping grooves on the surface of a cylindrical roller, and then clamping the processed cylindrical roller on a three-grip chuck of a lathe; at this moment, install the tool bit that the band pulley rolled on the blade holder of lathe to make the round roller hug closely cylindrical roller surface after aiming at the shaping groove, then go into the shaping inslot with the circular silk material card of stainless steel, the rethread lathe slowly drives cylindrical roller and rotates, like this alright roll the circular silk material of whole circle stainless steel in with the shaping inslot in succession the dysmorphism silk material of different cross sectional shapes through the gyro wheel.
Further, the sectional area of the stainless steel round wire is 8-10% larger than that of the special-shaped wire.
Furthermore, the cross section of the forming groove is square, rectangular, trapezoidal, convex or V-shaped.
Further, the stainless steel round wire is subjected to solution treatment before rolling, and is subjected to tempering treatment after rolling forming, wherein the tempering temperature is 350 ℃, and the heat preservation time is 1 h.
Due to the adoption of the technical scheme, the invention has the following advantages: the invention can process the stainless steel round wire into materials with different section sizes and shapes by adopting the existing lathe, replaces the processing mode of the existing cold punching die, and has the advantages of convenient operation, low manufacturing cost and high working efficiency. Meanwhile, the stainless steel round wire is subjected to solution treatment before rolling, so that the plasticity and ductility of the stainless steel round wire are improved, the rolling forming is facilitated, and the stainless steel round wire is subjected to tempering treatment after the rolling forming, so that the material stress is eliminated, and the service performance of the product is improved.
