Description
Technical field
The invention belongs to auto parts machinery manufacture field, and in particular to a kind of braking automobile adjustment arm arm body rod portion heat treatment is anti-
Distortion correction technique.
Background technology
Braking adjusting-arm plays an important role during braking automobile, and good braking automobile adjustment arm is able to ensure that wheel has
There is constant braking gap, braking safe is reliable, and braking is rapid reliable；Reduce material consumption, service life length, maintenance frequency
It is few, during production braking automobile adjustment arm, using 45 steel, because braking automobile adjustment arm arm body rod portion thickness is small, forge
Press forging out, after Overheating Treatment, its bar portion occurs warping phenomenon, and size is not up to standard, it is difficult to meets machining life
Production requires that, because the intensity and hardness in quenching rear braking adjustment arm arm body rod portion significantly improve, the difficulty of timing greatly promotes
And it is time consuming, percent defective is high, low production efficiency.
The content of the invention
To solve the above problems, the invention discloses a kind of heat treatment deformation correction of braking automobile adjustment arm arm body rod portion
Technique, method simple practical, it is substantially reduced the distortion inaccuracy that workpiece is brought by heat treatment.
To reach above-mentioned purpose, technical scheme is as follows：
A kind of braking automobile adjustment arm arm body rod portion heat treatment deformation correction process, comprises the following steps：
（1）Braking automobile adjustment arm arm body rod portion to be corrected is heated to 580-620 DEG C,
（2）By step（1）Workpiece after heating is put into the 3-4 seconds in ice bucket, takes out and is placed in middle hanging mould, starts 200
The hydraulic means of ton, the opposite direction that the deformation of arm arm body rod portion is adjusted to braking automobile press, and deflection is less than 3mm, hydraulic pressure
Device disposably presses the distance of workpiece to exceed the deflection of horizontal plane 1/3, and deflection presses by several times more than 3mm, hydraulic means, finally
Once the distance of workpiece is pressed to exceed the deflection of horizontal plane 1/3, the speed that pushes of hydraulic means is 6-8cm/min；
（3）By step（2）Workpiece afterwards is immediately placed in two pieces of flat boards, starts 100 tons of hydraulic means, flat board is pressed,
After natural cooling.
As a modification of the present invention, step（1）The firing rate is 50-60 DEG C/h.
As a modification of the present invention, step（3）The flat board is that thickness is 50-80mm.
As a modification of the present invention, step（2）、（3）The hydraulic means is one kind in hydraulic pump and jack.
As a modification of the present invention, the hydraulic means is provided with pressure gauge.
As a modification of the present invention, step（2）The hydraulic means connects with braking automobile adjustment arm arm body rod portion
Pad is with aluminium skin or copper sheet on contact.
A kind of braking automobile adjustment arm arm body rod portion heat treatment deformation correction process of the present invention, method are simply real
With for the workpiece heat after 45 steel forging fabricate-heat are handled to 580-620 DEG C, workpiece is changed into plasticity and toughness by elasticity, warm herein
The lower opposite direction of degree presses timing to workpiece, time saving and energy saving, and corrects stress and be preferably minimized, and the deformation of generation is also most
It is small, correction is become simple and easy；Workpiece is put into the 3-4 seconds in ice bucket before correction, and braking adjusting-arm is ensure that while correction
Intensity and impact resistance；Workpiece is placed in two pieces of flat boards after correction and pressed, can further improve calibration of workpieces deflection
Effect, the distortion inaccuracy for making workpiece be brought by heat treatment is in controllable state, and workpiece Slow cooling under residuals temperatures,
The overheating defects such as Wei Shi bodies, coarse grains can be improved, crystal grain thinning, uniform formation, eliminate internal stress, school of the present invention
Positive technique will not reduce the mechanical performance of workpiece, and deflection is reduced to 2mm/m.
A kind of braking automobile adjustment arm, total length 30cm or so of the present invention, arm body rod minister degree is in 17-18cm, thickness
1cm is spent, deflection is usually no more than 3mm after being heat-treated, if deflection disposably presses workpiece less than 3mm, hydraulic means
Distance must be exceeded horizontal plane, and opposite direction presses 1/3 deflection again；That is, if deflection is 3mm, hydraulic means from
It is 4mm that opposite direction, which disposably presses the distance of workpiece, if deflection reaches 5mm, hydraulic means presses by several times, presses 3mm for the first time,
Press 3mm again for the second time, this data is to grope obtained data according to practice for many years, and being sized to make of the distance that presses is produced
Raw residual deformation, the flexibility of workpiece can be eliminated after pressure load removing.
The beneficial effects of the invention are as follows：
A kind of braking automobile adjustment arm arm body rod portion heat treatment deformation correction process of the present invention, without being adjusted using high temperature
The method of matter, it is simple and practical, the distortion inaccuracy that workpiece is brought by heat treatment can be substantially reduced, and the machine of workpiece will not be reduced
Tool performance, ensure that calibration result.
