Abstract
The present invention discloses a steel wire needle back indentation milling-free processing method for straight-bar machines. The back indentation is formed on a bending leg device by punching with a punching head to flatten a needle rod when a front leg of a steel wire is bent. Then the bulged position on the needle rod is milled off when the front indentation is milled, and the processing method is finished. The present invention has the advantages of simple structure processing, easy operation, fluent back indentation shape, high surface smoothness, good consistency of the back indentation position, and low processing cost.
Description
Technical field:
The present invention relates to a kind of processing method of steel wire straight-bar machines pin.
Background technology:
In the knitting needle production process, the back lacks processing and fabricating, and general producer all adopts traditional diamond-making technique, with steel wire clubfoot, flattening, mill out the back with the alloy milling cutter then and lack earlier, quality is restive, especially the back lacks that to be easy to generate burr, wave seal, circular arc asymmetric etc., and the processing charges height.
Summary of the invention:
The object of the present invention is to provide a kind of processing simple, easy to operate, the back lacks shape smoothness, the steel wire needle back lack milling-free processing method for straight-bar machines that surface smoothness is high.
Technical solution of the present invention is:
A kind of steel wire needle back lack milling-free processing method for straight-bar machines is characterized in that: when the curved forward foot in a step of steel wire, use drift on clubfoot equipment, lack after once going out arc, shank is flattened, before milling when scarce, the boss on the mill off shank gets final product then.
Structure processing of the present invention is simple, easy to operate, the back lacks the shape smoothness, the surface smoothness height, and high conformity is put in back omission, and processing cost is low, when knitting needle used in braiding, yarn can reduce at lopping, knocking over resistance, has prolonged the service life of knitting needle, reduce the fault of assembling-disassembling simultaneously, improved the flatness of assembling-disassembling greatly.
Description of drawings:
Accompanying drawing 1 is the configuration diagram of the knitting needle that processes of the present invention.
The invention will be further described below in conjunction with drawings and Examples.
The specific embodiment:
A kind of steel wire needle back lack milling-free processing method for straight-bar machines when the curved forward foot in a step 1 of steel wire, use drift on clubfoot equipment, lack 2 after once going out arc, and shank is flattened, and before milling scarce 3 o'clock then, the boss that produces on the shank in the mill off flattening process got final product.
