Abstract
The present invention provides a kind of steel alloy or the auxiliary spring supports of spring steel material, which is characterized in that including fixed mounting plate, fixed mounting plate is surrounded by bolt mounting holes, and fixed mounting plate upper end is fixed with spring slot, and spring slot is perpendicular to fixed mounting plate；There are two the spring slot is set, two spring slots are set side by side, and compared with prior art, have the advantages that non-maintaining, impact resistance, driving torque are small.The invention uses high-grade alloy steel or spring steel material forging molding, and optimizes auxiliary spring support structure, compared with prior art, has many advantages, such as that wearability is good, yield rate.
Description
Technical field
The invention is related to steel alloy or spring steel auxiliary spring support.
Background technique
The auxiliary spring support now used has nodular iron casting and two kinds of low-alloy cast steel part, the auxiliary spring to form a complete production network in the market
Support product, mostly low-alloy cast steel part, the wearability of intensity, plasticity and product are superior to nodular iron casting, low-alloy casting
Though steel part has the characteristics that intensity is high, plasticity is good, exist as following drawbacks:
Its wearability is far below auxiliary spring, leads to its premature failure.
Low-alloy qualified casting is low, due to the presence of alloy material, casting crack easily occurs, yield rate is lower.
Cast article inevitably generates the defects of stomata, shrinkage cavity and porosity, seriously affects product service performance.
It is limited by casting material, integral quenching mode not can be used to guarantee the service performance of product, surface can only be used
Easily there is hardening flaw in quenching treatment, the casting of alloy material.
Summary of the invention
To solve the above problems, the invention provides a kind of steel alloy or spring steel auxiliary spring support, the invention
Using high-grade alloy steel or spring steel material, and auxiliary spring support structure is optimized, compared with prior art, good with wearability,
The advantages that yield rate.
In order to achieve the above objectives, the invention uses following technical scheme:
A kind of auxiliary spring support steel alloy or spring steel, use steel alloy or spring steel material forging molding.
A kind of steel alloy or spring steel auxiliary spring support, including fixed mounting plate, fixed mounting plate are surrounded by bolt peace
Hole is filled, fixed mounting plate upper end is fixed with auxiliary spring face, and auxiliary spring face is perpendicular to fixed mounting plate.
Preferably, the lower end of the fixed mounting plate is equipped with the lightening recesses of indent, the round and smooth setting in lightening recesses edge.
Preferably, the section in the auxiliary spring face is arc-shaped shape.
A kind of alloy auxiliary spring support heat treatment method,
A, it quenches: 840-870 degrees Celsius of hardening heat, oil quenching, cool time 30-90 minute；
B, it is tempered: 360-400 degrees Celsius of tempering temperature, tempering time 30-60 minutes, heat treatment hardness value HRC40-50.
Further, double tempering, 200-250 degrees Celsius of tempering temperature, tempering time 30-40 minutes.
The working principle and beneficial effect of the invention are shown:
The invention changes the manufacture of original auxiliary spring support, using steel alloy or spring steel forging molding energy
It enough realizes better mechanical property, specifically describes in embodiment below.
The invention uses arc auxiliary spring face, can preferably be cooperated with auxiliary spring plate.
Detailed description of the invention
Fig. 1 is the invention structural schematic diagram；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is the K direction view of Fig. 1.
Specific embodiment
The relevant technologies content that do not address below can be used or use for reference the prior art.
In order to make those skilled in the art better understand the technical solutions in the application, below in conjunction with the application reality
The attached drawing in example is applied, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described implementation
Example is merely a part but not all of the embodiments of the present application.Based on the embodiment in the application, this field is common
The application protection all should belong in technical staff's every other embodiment obtained without making creative work
Range.
It is a kind of using steel alloy or the auxiliary spring support of spring steel material forging molding.
The invention provides a kind of steel alloy or spring steel auxiliary spring support, including fixed mounting plate 1, fixed mounting plate
It is surrounded by bolt mounting holes 2；1 upper end of fixed mounting plate is fixed with auxiliary spring face 3, lower end and is equipped with the lightening recesses 4 of indent, loss of weight
The round and smooth setting in 4 edge of groove.
Auxiliary spring face 3 is perpendicular to fixed mounting plate 1.There are two the auxiliary spring face 3 is at least set side by side.
The section in the auxiliary spring face is arc-shaped shape, and circular arc is bent upwards.
Using the above steel alloy or spring steel material, product entirety modifier treatment HRC40-50, mechanical property is compared such as
Under:
To improve thermal effectiveness, in double tempering, 200-250 degrees Celsius of tempering temperature, tempering time 30-40 minutes.
Existing technical parameter is as follows:
It is compared from upper table, the material comprehensive mechanical performance of the invention will be much higher than existing ZGD650-830.
To sum up, due to the improvement of material, and in order to improve the fabrication yield of product, the compactness of product is improved, I am single
Position is manufactured using forging method, and forge piece is widely used in the field of stressed member, safety member.Due to being that forging class produces
Product, interior tissue is close, does not have the internal flaws such as stomata, sand holes, the shrinkage porosite that casting generates.
Existing auxiliary spring support is fabricated to material component identical with auxiliary spring, due to the auxiliary spring support material and auxiliary spring material
Unanimously, therefore individually auxiliary spring support will not be worn substantially.
Since the product hardness is lower than auxiliary spring plate hardness, therefore the bracket can only be worn in the case where wearing, it will not be to pair
Spring causes big abrasion, meets the requirement of replacement smallclothes.
The above is only the preferred embodiment of the application, is made skilled artisans appreciate that or realizing this Shen
Please.Various modifications to these embodiments will be apparent to one skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the application.Therefore, the application
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest scope of cause.
