Description
Technical field
The invention belongs to automobile parts manufacture fields, and in particular to a kind of braking automobile adjustment arm arm body rod portion heat treatment is anti-
Distortion correction technique.
Background technique
Braking adjusting-arm plays an important role during braking automobile, and good braking automobile adjustment arm can ensure that wheel has
There is constant braking gap, braking safe is reliable, and braking is reliable rapidly；Reduce material consumption, long service life, maintenance frequency
It is few, during producing braking automobile adjustment arm, forged using 45 steel since braking automobile adjustment arm arm body rod portion thickness is small
Press forging out, after Overheating Treatment, bar portion will appear warping phenomenon, and size is not up to standard, it is difficult to meet machining life
It produces and requires, since the intensity and hardness in quenching rear braking adjustment arm arm body rod portion significantly improve, the difficulty of timing is greatly promoted
And time-consuming, high rejection rate, production efficiency are low.
Summary of the invention
To solve the above problems, the invention discloses a kind of adjustment arm arm body rod portion's heat treatment deformation corrections of braking automobile
Technique, method simple practical are substantially reduced workpiece because being heat-treated bring distortion inaccuracy.
In order to achieve the above objectives, technical scheme is as follows:
A kind of braking automobile adjustment arm arm body rod portion heat treatment deformation correction process, comprising the following steps:
(1) braking automobile adjustment arm arm body rod portion to be corrected is heated to 580-620 DEG C,
(2) workpiece after step (1) heating is put into ice bucket 3-4 seconds, takes out and is placed in intermediate hanging mold, starting
200 tons of hydraulic device presses to the opposite direction of braking automobile adjustment arm arm body rod portion deformation, and deflection is less than 3mm, liquid
It is more than 1/3 deflection of horizontal plane that pressure device, which disposably presses the distance of workpiece, and deflection is more than 3mm, and hydraulic device presses by several times, most
Once the distance of pressure workpiece is more than 1/3 deflection of horizontal plane afterwards, and the pushing speed of hydraulic device is 6-8cm/min；
(3) workpiece after step (2) is immediately placed in two pieces of plates, starts 100 tons of hydraulic devices, pressure is imposed to plate
Power, after natural cooling.
As an improvement of the present invention, step (1) heating speed is 50-60 DEG C/h.
As an improvement of the present invention, step (3) plate is with a thickness of 50-80mm.
As an improvement of the present invention, step (2), (3) described hydraulic device are one of hydraulic pump and jack.
As an improvement of the present invention, the hydraulic device is equipped with pressure gauge.
As an improvement of the present invention, step (2) hydraulic device adjusts connecing for arm arm body rod portion with braking automobile
Pad is on contact with aluminium skin or copper sheet.
A kind of braking automobile of the present invention adjusts arm arm body rod portion heat treatment deformation correction process, and method is simply real
With by 45 steel forging fabricate-heat, treated that workpiece is heated to 580-620 DEG C, and workpiece is changed into plasticity and toughness by elasticity, warm herein
It spends lower opposite direction to press timing to workpiece, time saving and energy saving, and correct stress and be preferably minimized, the deformation of generation is also most
It is small, so that correction is become simple and easy；Workpiece is put into ice bucket 3-4 seconds before correcting, and ensure that braking adjusting-arm while correction
Intensity and impact resistance；Workpiece is placed in two pieces of plates after correction and is pressed, can further improve calibration of workpieces deflection
Effect, make workpiece because heat treatment bring distortion inaccuracy be in controllable state, and workpiece Slow cooling under residuals temperatures,
The overheating defects such as Wei Shi body, coarse grains can be improved, refinement crystal grain, eliminates internal stress, school of the present invention at uniform formation
Positive technique will not reduce the mechanical performance of workpiece, and deflection is reduced to 2mm/m.
A kind of braking automobile of the present invention adjusts arm, and overall length 30cm or so, 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, less than 3mm, hydraulic device disposably presses workpiece
Distance must be exceeded horizontal plane, and opposite direction presses 1/3 deflection again；That is, if deflection be 3mm, hydraulic device from
It is 4mm that opposite direction, which disposably presses the distance of workpiece, if deflection reaches 5mm, hydraulic device presses by several times, presses 3mm for the first time,
Press 3mm again for the second time, this data is the data groped according to the practice of many years, and the size for the distance that presses can make to be produced
Raw residual deformation can eliminate the curvature of workpiece after pressure load removing.
The beneficial effects of the present invention are:
A kind of braking automobile of the present invention adjusts arm arm body rod portion heat treatment deformation correction process, without height
The quenched method of temperature, it is simple and practical, workpiece can be substantially reduced because being heat-treated bring distortion inaccuracy, and workpiece will not be reduced
Mechanical performance, ensure that calibration result.
