Abstract
The invention provides a valve spring and a processing technology thereof. The valve spring comprises a spring body, wherein the spring body is in an integral structure, and is an elongated metal strip; a crease is formed in the middle of the metal strip; the cross section of the spring body is V-shaped; a plurality of notches which are arranged in order are formed in two sides of the spring body; the spring body is in an S-shaped structure after being provided with the notches, and is made of an alloy steel material; the length of the spring body is 13-15cm; the width of the spring body is 1-1.3cm; the thickness of the spring between two notches is 0.1-0.2cm. Compared with an existing valve spring, the valve spring has the beneficial effects of being relatively durable, relatively long in service life, relatively firm, relatively convenient to use, and very convenient to produce.
Description
Technical field
The present invention relates to a kind of spring, particularly a kind of novel valve spring be applicable on valve.
Background technique
Now valve spring commercially, working life is all very short, and service time is long to be just easily corroded, so need often to change, but also insecure, so need a kind of valve spring and processing technology thereof just can address these problems.
Summary of the invention
For existing technical deficiency, the invention provides a kind of valve spring and processing technology thereof.
To achieve these goals, the technical solution used in the present invention is: a kind of valve spring, comprise spring body, described spring body is integral type structure, described spring body is the metal bar of a long strip, and the centre of metal bar is provided with folding line, and the cross section of spring body is V-shaped shape, the both sides of spring body are equipped with some tactic otch, are provided with the S-shaped structure of the spring body after otch.
Described spring body is that alloy steel material is made.
The length of described spring body is 13cm ~ 15cm, and width is 1cm ~ 1.3cm, and between two otch, the thickness of spring is 0.1cm ~ 0.2cm.
A processing technology for valve spring, the processing technology of this spring is:
(1) adopt 50CrVA spring steel, extruded the shape of spring by Presser Dashing.
(2) untreated spring is carried out following process:
1) normalizing: heating-up temperature 850 ~ 870 DEG C, holding time 1h, cools naturally.
2) quench: adopt primary quenching technique, quenching temperature is 860 DEG C, holding time 0.5 ~ 1h.
3) medium-temperature tempering: tempering heating-up temperature is 350 DEG C, holding time is 1.5 ~ 2h.
4) destressing tempering: tempering temperature is 160-180 DEG C, holding time 1-2h, cools or water-cooled in air naturally.
Beneficial effect of the present invention: this product is more durable than existing valve spring, longer service life, more firmly, uses more convenient, produces also very convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of valve spring and processing technology thereof, comprise spring body 1, described spring body 1 is integral type structure, described spring body 1 is the metal bar of a long strip, and the centre of metal bar is provided with folding line, and the cross section of spring body 1 is V-shaped shape, the both sides of spring body 1 are equipped with some tactic otch, are provided with the S-shaped structure of the spring body after otch 1.
Described spring body 1 is made for alloy steel material, and the spring that alloy steel material is made is more firm, longer service life.
The length of described spring body 1 is 13cm ~ 15cm, and width is 1cm ~ 1.3cm, and between two otch, the thickness of spring is 0.1cm ~ 0.2cm, selects the spring sizes of different model according to the valve of different model.
Valve spring and a work technique, the processing technology of this spring is:
(1) adopt 50CrVA spring steel, extruded the shape of spring by Presser Dashing.
(2) → enhancement process (Shot peening) is completed by untreated spring → heat treatment in advance (normalizing) → enhancement process (quenching medium-temperature tempering) → alignment → stabilizing treatment (destressing tempering) → heat treatment.
1) normalizing: heating-up temperature 850 ~ 870 DEG C, holding time 1h, cools naturally.
2) quench: adopt primary quenching technique, quenching temperature is 860 DEG C, holding time 0.5 ~ 1h.
3) medium-temperature tempering: tempering heating-up temperature is 350 DEG C, holding time is 1.5 ~ 2h.
4) destressing tempering: tempering temperature is 160-180 DEG C, holding time 1-2h, cools or water-cooled in air naturally.
This product is by being shaped by punch ram by the material chosen, and processes very convenient, and elasticity is also fine, is not easy burn into and damages, long service life.
