Description
Technical field
The present invention relates to automobile stabilizer bar and manufacture method thereof.
Background technology
The main material of present domestic solid stabilizing rod is must be through the material of quenching and temper.This class is mainly annealing and hot-finished material, as hot rolled steel, silicon-manganese steel, chrome vanadium steel, chrome silicon steel etc.Its process steps is as shown in Figure 1: materials procurement → blanking in blanker → carrying out end machining → clod wash in cold bending machine → heat, quench → tempering in drawing furnace → carry out cold sizing → adopt powder to carry out finish coat at last on the punch press in the heating in medium frequency stove in the cold sizing machine.
Must there be following shortcoming in use through the material of quenching and temper:
1. material surface is of low quality, has hindered the High Performance and the high dimensional accuracy of stabilizer rod product.
2. in order to obtain the High Performance of stabilizer rod product, have to raw MAT'L is reprocessed---peeling or polishing.Cost of product is increased greatly, and time-to-market is extended.
3. increased the road preface of stabilizer rod production and processing, the production cycle is prolonged.
4. increased the hidden danger of quality of stabilizer rod product, heating, quenching very easily make the product distortion.
Equally, use above-mentioned technology also to have following shortcoming:
1, employing is heated, is quenched in the heating in medium frequency stove, and the heating in medium frequency stove is most of by import at present, costs an arm and a leg;
2, also will add one tempering process after heating, the quenching process, the time of this tempering process is long, about 1 hour; And the temperature height of tempering needs about 400 ℃, has both wasted fund, wastes energy again.
Summary of the invention
The present invention is in order to overcome the above-mentioned shortcoming that prior art exists, and a kind of automobile stabilizer bar and the manufacture method thereof that provide adopt this method can reduce equipment investment, reduce production costs, and shorten the production cycle, thereby improves the quality of products and economic benefit.
The technical scheme that the present invention takes is: a kind of automobile stabilizer bar, be characterized in, and adopt the Q-tempering material to constitute.
Above-mentioned a kind of automobile stabilizer bar, wherein, described Q-tempering material comprises oil hardening steel and water-quench steel wire.
The manufacture method of automobile stabilizer bar is characterized in, may further comprise the steps:
A, selective quenching tempering material are as the raw MAT'L of producing stabilizer rod;
B, in blanker blanking;
C, on punch press, carry out end machining;
D, clod wash in cold bending machine;
E, in drawing furnace, carry out the destressing tempering;
F, in the cold sizing machine, carry out cold sizing;
G, adopt powder to carry out finish coat at last.
The manufacture method of above-mentioned automobile stabilizer bar, wherein, the temperature of the described drawing furnace of step c is 150 ℃～250 ℃.
The manufacture method of above-mentioned automobile stabilizer bar, wherein, the time of tempering is 20 minutes～40 minutes in the described drawing furnace of step c.
The manufacture method of above-mentioned automobile stabilizer bar, wherein, described Q-tempering material is made of oil hardening steel or water-quench steel wire.
Because the present invention has adopted above technical scheme, adopt Q-tempering material manufacture automobile stabilizer bar, therefore do not need heating after stabilizer rod is shaped, quench, only need stress relieving to get final product, equipment investment is reduced, and reduced productive costs, shortened the production cycle, improved the quality of products and economic benefit.
And because Q-tempering material fatigue life height, anti-relaxation property are good, therefore make the stabilizer rod processing characteristics stable, can obtain better surface quality.
Description of drawings
Concrete characteristic performance of the present invention is further described by following embodiment and accompanying drawing thereof.
Fig. 1 is the flow process chart of prior art automobile stabilizer bar.
Fig. 2 is the flow process chart of automobile stabilizer bar of the present invention.
The specific embodiment
Automobile stabilizer bar of the present invention adopts Q-tempering material for example water-quench steel wire or oil hardening steel formation.Its manufacture method may further comprise the steps:
A, selective quenching tempering material are as the raw MAT'L of producing stabilizer rod; This Q-tempering material has height fatigue life, advantage that anti-relaxation property is good, therefore makes the stabilizer rod processing characteristics stable, can obtain better surface quality.
B, in blanker by suitable requirement blanking;
C, on punch press, carry out end machining;
D, clod wash becomes design shape in cold bending machine;
E, in drawing furnace, carry out the destressing tempering; The temperature of this drawing furnace is controlled at about 150 ℃～250 ℃.The time of tempering was controlled at 20 minutes～40 minutes in drawing furnace.The time of this tempering and the temperature of drawing furnace are inversely proportional to, the temperature height in the drawing furnace, and then the time of tempering is short; Otherwise the temperature in the drawing furnace is low, and then the time of tempering is long.
F, in the cold sizing machine, carry out cold sizing then;
G, adopt powder to carry out finish coat at last.
Exemplify several concrete selection water-quench steel wires below and describe method of the present invention in detail (certainly as the raw-material embodiment that produces stabilizer rod, adopting oil hardening steel identical as the raw-material method of producing stabilizer rod with employing water-quench steel wire as the raw-material method step of producing stabilizer rod, only is the raw MAT'L difference):
