Continuous near-net-type rolling equipment of linear Slide rail material

Abstract

The present invention discloses a continuous rolling apparatus near-net type linear slide material, including a wire feeding mechanism, a tension control mechanism, at least one group for rolling extension mechanism, an electromagnetic induction heating system and a four-roll type near Net type rolling mechanism. The wire feed mechanism is used to transport a timber embryos; the tension control mechanism is used to control a germ material to maintain proper speed of transport and transport tension; the mechanism for rolling extension that contains the electromagnetic induction heating system and the four-roll style near-net-type rolling mechanism, in which the electromagnetic induction heating system comprises a temperature feedback control device and the frequency with a power control system, the temperature feedback control means for detecting germ material surface temperature and the frequency and power control systems heating embryo timber and timber control embryos maintained at a temperature suitable for rolling; the four-roll type rolling near-net mechanism is used for the embryo rolling plastic processing material, and includes four planetary arrangement of rolls, which are for simultaneously rolling section of the embryo surrounding material delay. Rolling apparatus of the present invention may be continuous mass production, and dramatically reduce the manufacturing time and reduce manufacturing costs.

Description

technical field [0001] The invention relates to a continuous near-net rolling equipment for linear slide material, in particular to a continuous near net rolling equipment for four-roll rolling plastic processed linear slide material. Background technique [0002] At present, the drawing and drawing manufacturing process of common linear slide rail materials is as follows: figure 1 As shown, the steel wire or bar is first subjected to spheroidizing heat treatment such as figure 2 The spherical structure (spheroidite) is used to avoid microcracks inside the slide rail due to work hardening during the drawing of the eye mold or the drawing of the roll. image 3 It is the time-temperature-transformation diagram of carbon steel, the spheroidizing temperature is about 700°C, and image 3 Knowing that it takes about 18 to 24 hours for the metamorphosis to complete. After the steel wire or bar is spheroidized, straightening, cleaning and derusting, wire drawing or drawing proce...

AI Technical Summary

Problems solved by technology

[0003] The processing of the above-mentioned linear slide rail materials is complicated, and each ballizing time takes about 18-24 hours, resulting in very long working hours and high processing costs

In addition, the spheroidization time is very long, which is easy to cause decarburization on the surface, resulting in poor quality of slide rail materials
