Embodiment 1

[0019] The processing method of I-type integral oil ring wire used in the piston ring industry:

[0020] The first step of rolling: the raw material wire rod is linearly routed through the rolling equipment, and rolled on the four sections of the upper, lower, left, and right sides at the same time to obtain the required I-shaped section shape;

[0021] The second step of annealing: the rolled wire rod is linearly routed through the annealing furnace for annealing, and then rolling and annealing are performed after annealing, and this is repeated 3-8 times to obtain a type I integral oil ring wire rod without quenching and tempering;

[0022] The third step: Quenching and tempering heat treatment: the steel wire is linearly and continuously routed and quenched, and then tempered in an inert protective gas atmosphere. After quenching and tempering, there is a linear continuous water-cooled rapid cooling treatment, and the quenching temperature is 860 ° C ~ 1150°C, quenching coo...

Embodiment 2

[0025] The processing method of the I-type integral oil ring wire with holes for the piston ring industry:

[0026] The first step of rolling: the raw material wire rod is linearly routed through the rolling equipment, and rolled on the four sections of the upper, lower, left, and right sides at the same time to obtain the required I-shaped section shape;

[0027] The second step of annealing: the rolled wire rod is linearly routed through the annealing furnace for annealing, and then rolling and annealing are performed after annealing, and this is repeated 3-8 times to obtain a type I integral oil ring wire rod without quenching and tempering;

[0028] The third step of punching: punching the wire rod on the punching machine to obtain a non-tempered I-type integral oil ring wire rod with holes;

[0029] The fourth step: quenching and tempering heat treatment: the steel wire is linearly and continuously routed and quenched, and then tempered in an inert protective gas atmosphe...

Abstract

The present invention relates to a wire material production method, in the concrete, it relates to a production method of I-type integral oil ring wire material in piston ring industry. It is characterized by that said production method includes the following steps: rolling: making raw material by passed through rolling equipment, at the same time rolling upper, lower. Left and right four sections so as to obtain the required section form; making the rolled wire material be passed through annealing furnace and making annealing, then further rolling annealed wire material and annealing, repeating the above-mentioned steps for 3-8 times so as to obtain the invented wire material.

Description

Technical field: [0001] The invention relates to a wire rod processing method, in particular to a wire rod processing method in the piston ring industry, and also provides its equipment. Background technique: [0002] The wire used for I-type integral oil rings for motor vehicle piston rings has complex cross-sectional shapes and requires high dimensional accuracy. At present, only a few foreign manufacturers can produce such products, and their production investment is huge, and the product prices are expensive. Neither the shape nor the quality can meet the requirements, and this type of product cannot be produced, so it is difficult to make a breakthrough in technology. Invention content: [0003] The purpose of the present invention is to overcome the above-mentioned disadvantages and provide a processing method for the I-type integral oil ring wire used in the piston ring industry. The method is simple in production, low in cost, and has excellent product shape and qu...
