Method and machines for machining wire rods

Abstract

The invention discloses a method and machines for machining wire rods. The centers of two machines are respectively provided with a center through hole, three punched holes distributed in an equiangular mode are formed in the periphery of each center through hole, and each punched hole inclines by a certain degree. In addition, a supporting piece is arranged in each punched hole of the machines, and three rolling rods are arranged in a staggered mode after the two ends of each of three rolling rods are arranged in the supporting pieces in the two machines respectively. Three bevel gears are arranged in one machine side by side, and therefore the three rolling rods can rotate under the effect that powered bevel gears drive each bevel gear. When the wire rods enter the machines, the wire rods are rolled and squeezed because the wire rods make contact with the three rolling rods, and therefore middle sections of the wire rods can be in machined states and with diameters smaller than front sections and back sections of the wire rods. In this way, the purposes of improving stress strength, saving materials of the wire rods and being lightened under the condition that internal textures of machined wire rods are changed are achieved.

Description

technical field [0001] The present invention relates to a wire rod processing method and machine tools. Three rolling rods arranged in an oblique and staggered manner are placed in the two machines, so that when the wire enters between the two machines, it is subjected to three rolling rods in rotation. The rods are in contact with each other to perform rolling and extrusion action, and gradually move to make the middle section of the wire rod have a thinner diameter than the front and rear sections; it is to improve the force by changing the internal structure of the processed wire rod Strength, and save wire materials and light weight purposes. Background technique [0002] By the way, generally there are many ways to process the wire rods to be tapered, but all of them will leave a lot of traces after processing on the surface of the wire rod itself, and also cause the processed wire rods to have a bad appearance, so in the details After additional research, it is believ...

[0002] By the way, generally there are many ways to process the wire rods to be tapered, but all of them will leave a lot of traces after processing on the surface of the wire rod itself, and also cause the processed wire rods to have a bad appearance, so in the details After further research, it is believed that the processing method of wire rod should be completely changed to solve the problem.
