Place, carries out drawing side, chamfered to raw band, obtains with the woollen band for making setting cross-sectional shape structure；
Step 3 guides woollen band obtained in step 2 into material storage mechanism；
Woollen band in material storage mechanism is led to the heating mechanism of scroll spring molding equipment, is heated to by step 4
600-650 DEG C,
Step 5, cans: the woollen band after step 4 heats is passed through the coiled body of scroll spring molding equipment
Place, is crimped, and carries out bending forming, the cutoff process of scroll spring both ends end after curling simultaneously, obtains scroll spring
Semi-finished product；
Step 6, heat treatment: the merging of semi-finished product obtained in the step 5 of river Equipment for Heating Processing is heat-treated, and is answered in elimination
Power；
Step 7 carries out antirust treatment to through step 6 treated semi-finished product, obtains scroll spring finished product.
Further, the material storage mechanism in step 3 is material-storing box, and the width of material-storing box is consistent with woollen bandwidth, storing
One end of box is opening, the other end is outlet.
Further, the heating method of the heating mechanism in step 4 is high-frequency heating.
Further, the time of cans is 1.64-2s in step 5.
The beneficial effects of the present invention are: using the above scheme, the continuity for realizing scroll spring efficiently produces, woollen band
It is first to heat to preference temperature, the quick cans in the case where keeping temperature, gib head molding, cutting synchronously complete, and form
It is high-efficient, internal stress generate it is small, cans, gib head molding, cutting when, pressure, the web length of the mold of coiled body
The control of equal Parameters Integrated Survey Methods, and the instant playback of originating party formula is shown by number, the elasticity of molding precision and spring is improved, is made
The elastic force of the scroll spring obtained is stronger, has longer service life, and service performance is stablized.
Specific embodiment
A kind of embodiment 1: processing technology of scroll spring, which comprises the following steps:
Step 1 selects the band steel band of 60CrMnBA material as raw band, continuous band steel band is placed into scrollwork bullet
On the charging tray of spring molding equipment, convenient for the consecutive production of scroll spring；
Step 2 draws side, chamfer machining:
Raw band on charging tray is guided at the reshaping device of scroll spring molding equipment, to raw band carry out drawing side,
Chamfered, reshaping device include the grinding subassembly for drawing side component, upper and lower end face of the chamfer angle component of both side ends, both ends, are beaten
Dirt, the rusty stain for grinding off raw material belt surface carry out shaping to raw band, and the both ends for arriving raw material keep specific shape, obtain
With the woollen band for making setting cross-sectional shape structure；
Step 3 guides woollen band obtained in step 2 into material storage mechanism, and the effect of material storage mechanism is temporary woollen
Band, the treatment effeciency of the subsequent handling of woollen band are less than the treatment effeciency of the front process of woollen band, woollen band are carried out temporary
Storage, orderly produced convenient for the continuity of scroll spring, and in the case where a certain mechanism malfunction, other processes
Processing can still continue, and guarantee that the processing of globality is uninterrupted, guarantee production efficiency；
The woollen band drawn by material storage mechanism is led to the heating mechanism of scroll spring molding equipment to hair by step 4
Material strip is heated, and woollen band is heated to 600 DEG C, reduces the hardness of raw band, raw band hardness reduces 300HV, after being convenient for
Continuous to carry out cans to woollen band, hardness reduces, and improves the precision of cans, and greatly avoid the raw material in curling
Band band body generates internal stress；
Step 5, cans:
Woollen band after step 4 heats is passed through at the coiled body of scroll spring molding equipment in the case where heat preservation,
It is crimped after processing, in curling, band body hardness is reduced, and convenient for molding, improves the precision of cans, avoids answering in generation
Power, improves the Mass accuracy of scroll spring, after cans, by the mold at coiled body to the hook at the both ends of scroll spring
Head carries out bending forming, and bending forming while cuts off gib head and raw band junction, obtain scroll spring partly at
Product；
Step 6, heat treatment:
Semi-finished product obtained in step 5 are sent into tempering furnace and carry out average tempering processing, the control of average tempering temperature exists
400-435 DEG C, tempering time 30min, reduces, eliminates internal stress, improve elasticity；
Step 7, antirust treatment:
Surface black oxidation processes are carried out to the semi-finished product of scroll spring obtained in step 6, to the half of scroll spring at
Product surface carries out alkaline oxygenated method, oxidation film with a thickness of 0.5-1um, the temperature of solution is 130-145 DEG C in oxidation, oxidation
Time control then carries out surface and coats antirust oil processing, obtain scroll spring finished product in 40-120min；
Step 8 is examined:
Using rigidity, fatigue strength and the hot constant temperature test damage of the scroll spring finished product that conventional detection apparatus detects
It loses, is packed and stored scroll spring after detection is qualified.
Material storage mechanism in above-mentioned steps three is material-storing box, and the width of material-storing box is consistent with woollen bandwidth, material-storing box
One end is opening, the other end is outlet, after woollen band is entered by open end, can be bent storing in S type in material-storing box, due to
Material-storing box width is consistent with woollen bandwidth, the disorderly band situation for avoiding woollen band from occurring mutually winding in material-storing box, woollen band
The effect of being sent out by outlet, storing realized by simple structure.
The heating method of heating mechanism in above-mentioned steps four be high-frequency heating, high-efficient, the homogeneous heating of high-frequency heating,
It is easy to implement the high-efficiency and continuous production of scroll spring.
The time of cans is 1.64-2s in above-mentioned steps five, and shaping efficiency is fast, the case where woollen band keeps temperature
Under, rapid shaping promotes the formed precision for improving scroll spring, reduces the generation of internal stress, improves the use effect of scroll spring
Fruit.
Woollen band is first to heat to preference temperature, then keeps quick cans in the case where temperature, gib head molding, cutting
It synchronously completes, molding high-efficient, internal stress generation is small, when cans, gib head are formed, are cut off, the mold of coiled body
The control of the Parameters Integrated Survey Methods such as pressure, web length, and by number show the instant playback of originating party formula, improve molding precision and
The elastic force of the elasticity of spring, the scroll spring as made from above-mentioned technique is stronger, has longer service life, and service performance is steady
It is fixed.
