Cooling medium in, and swing back and forth in cooling medium (being liquid level at A in Fig. 2, B places are axletree underwater penetration), simultaneously
Pressure medium injects cooling system 7 and water is sprayed into axletree inwall by the one end of axletree 1, and with cooling axle inwall, axletree is entered
Row quenching, after the cool time arrives, quenching platform 3 is shown the water surface by swing arm 8 together with clamped axletree 1 again, and is resetted, then
Three groups of clamping cylinders 23 unclamp axletree, and manipulator removes the axletree that quenching is finished from quenching platform 3, then again will be next
Root axletree to be quenched is put on quenching platform 3.It is clamped and is aligned to the process for completing to quench not from prestressing force straightener
More than 25 seconds.Also, in quenching process, the clamping force of clamping unit pair is changed over time so that axletree is quenched
Preferable leveling effect is reached in journey.The quenching tank of left and right two shares the workpiece conveyer frames of a centre, the work heated in Fig. 1
Part is sent between two quenching tanks by workpiece conveyer frames, and is placed into by manipulator in the vee-block 52 of both sides, is subtracted as far as possible
In the case of few frock configuration, the efficiency of axletree heat treatment is improved.
The beneficial effects of the utility model are as follows：
First, clamping unit is fixed using side, and opposite side clamping cylinder, which is promoted, to be clamped, it is ensured that workpiece is flat in aligning
Straight degree.
Secondly, before workpiece enters water quenching, clamping unit applies prestressing force and aligning is clamped to axletree, then quenches
When, during workpiece axial deformation, the first sliding block also follows workpiece axial movement, it is to avoid workpiece axial deformation is excessive and ruptures, and
Left gripping block and right gripping block are for the persistent pressure of workpiece, and clamping force constantly adjusts, and control workpiece radial deformation.
Again, in the application quenching apparatus, the Fixture Design such as clamping unit, push unit can control axletree to deform very well,
The performance requirement of axletree is met, process is manually aligned without rear road.
Exemplary explanation is simply carried out to utility model above, specific implementation of the present utility model is not limited to
In this.Any insubstantial modifications carried out using design of the present utility model and technical scheme, are protected of the present utility model
Within the scope of shield.
