Abstract
The invention relates to a quick turning processing method for a suspension torsion bar spring. The quick turning processing method comprises the following steps of: taking a raw material; using a centerless car to perform centerless car grinding to the raw material; sawing off the raw material after the centerless car grinding is performed; forging the two ends of the sawed raw material so that the two ends of the sawed raw material form heads; and performing fine turning to the heads of the two ends of the raw material; and grinding the heads. With the adoption of the quick turning processing method for the suspension torsion bar spring, the processing time is saved, and the cost is reduced; and the turning processing time of the single suspension torsion bar spring in the original process flow is 50 seconds, and the turning processing time of single suspension torsion bar spring in the process flow of the quick turning processing method is 40seconds, so that the time is saved by 20%.
Description
Technical field
The present invention relates to hang the torsion-bar spring manufacture technology field, particularly relate to a kind of suspension torsion-bar spring fast turning processing method.
Background technology
The suspension torsion-bar spring is the important flexible member in the suspension, general draw ratio 31:1 to 42:1, and material is the high duty alloy spring steel, and supporting quantity is 16 every, and the process-cycle is long, difficulty is large, belong to typical slender axles part.The mechanical performance of material is as follows: tensile strength (σ b) is 1470Mpa, yield point (σ s) for 1330Mpa, elongation after fracture (δ) are 7%, the contraction percentage of area (Ψ) is 35%, impact absorbing energy (Aku2) is 269kgf/mm for 31J, Brinell hardness (HB)
2, elastic properties of materials is large, and intensity is high, and hardness is high, belongs to hard-cutting material, and follow-up flaw detection, shot blasting on surface etc. all are to the reinforcement of front operation or remedy that turning processing is the major control point of its processing.Existing turning process may further comprise the steps: saw expect, is forged, alignment, milling head, centering, rough turn, finish turning, alignment, mill bar section, bistrique section, grind R, adopt above-mentioned technological process to finish a turning processing of hanging torsion-bar spring and need 50 seconds, and overall process is manual operation, and operating personnel's working strength is very large.
Summary of the invention
Technical problem to be solved by this invention provides a kind of suspension torsion-bar spring fast turning processing method, can save process time and reduce labour intensity.
The technical solution adopted for the present invention to solve the technical problems is: a kind of suspension torsion-bar spring fast turning processing method is provided, may further comprise the steps:
(1) gets raw material;
(2) utilization is not in the mood for car raw material is not in the mood for the car mill;
(3) cut the raw material that carried out not being in the mood for the car mill;
(4) forge the raw material two ends of cutting, make the raw material two ends of cutting present head;
(5) head at raw material two ends carried out finish turning;
(6) bistrique section.
Adopt automatic loading and unloading device and charging/discharging device that raw material are not in the mood for the car mill in the described step (2).
Beneficial effect
Owing to adopted above-mentioned technical scheme, the present invention compared with prior art has following advantage and good effect:
The present invention can save process time, has reduced cost, and the single turning of former technological process process time is 50 seconds, and the single turning of technological process of the present invention process time is 40 seconds, has saved 20%.Adopt among the present invention and be not in the mood for the automatically control of car mill, surface quality is comparatively stable.And only process with peripheral milling behind the head employing finish turning after forging, connect all smoothly feeds of cutter place, the defective that does not exist stress to concentrate, guaranteed product quality, utilization is not in the mood for car, is all adopted automatic loading and unloading device and charging/discharging device without the smart aligning of being careless or thoughtless by nature, centreless grinding loading and unloading, original technological process is manual operation entirely, greatly reduces labour intensity.
Though original processes is through repeatedly alignment, but linearity and all be difficult to assurance in more among a small circle concavo-convex defective in the longer scope, and all be manually alignment, uncontrollable factor is too many, often only after mill processing, check out, and this moment, product itself was scrapped.And the present invention just has the function of automatic straightening linearity without the smart alignment itself of being careless or thoughtless by nature, and not being in the mood for the car employing is that workpiece is motionless, the four blade tool is center circumferential and rotates cutting, makes product all have preferably linearity before grinding, may have the possibility of scrapping because linearity is defective hardly.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiments of the present invention relate to a kind of suspension torsion-bar spring fast turning processing method, may further comprise the steps:
(1) get raw material, raw-material shape, as shown in Figure 1;
(2) utilization is not in the mood for car raw material is not in the mood for the car mill, and the shape behind the car mill as shown in Figure 2; Wherein, adopt automatic loading and unloading device and charging/discharging device that raw material are not in the mood for the car mill.
(3) cut the raw material formation shape as shown in Figure 3 of carrying out not being in the mood for the car mill;
(4) forge the raw material two ends of cutting, make the raw material two ends of cutting present head, see Fig. 4;
(5) finish turning formation shape is as shown in Figure 5 carried out in the head at raw material two ends;
(6) bistrique section forms shape as shown in Figure 6.
Be not difficult to find that the present invention can save process time, has reduced cost, the single turning of former technological process process time is 50 seconds, and the single turning of technological process of the present invention process time is 40 seconds, has saved 20%.Adopt among the present invention and be not in the mood for the automatically control of car mill, surface quality is comparatively stable.And only process with peripheral milling behind the head employing finish turning after forging, connect all smoothly feeds of cutter place, the defective that does not exist stress to concentrate, guaranteed product quality, utilization is not in the mood for car, is all adopted automatic loading and unloading device and charging/discharging device without the smart aligning of being careless or thoughtless by nature, centreless grinding loading and unloading, original technological process is manual operation entirely, greatly reduces labour intensity.Though original processes is through repeatedly alignment, but linearity and all be difficult to assurance in more among a small circle concavo-convex defective in the longer scope, and all be manually alignment, uncontrollable factor is too many, often only after mill processing, check out, and this moment, product itself was scrapped.And the present invention just has the function of automatic straightening linearity without the smart alignment itself of being careless or thoughtless by nature, and not being in the mood for the car employing is that workpiece is motionless, the four blade tool is center circumferential and rotates cutting, makes product all have preferably linearity before grinding, may have the possibility of scrapping because linearity is defective hardly.
