Adopt quench cooled system of the present invention to carry out the method for quench cooled, comprise the steps:
(1), quenching workpiece is placed on operator's console, and column is moved downward in the hardening liquid in quenching workpiece dip quench groove;
(2), motor drives walking dolly on support, to do a to-and-fro movement, make quenching workpiece in hardening liquid along walking moving of car direction move carry out cooling;
(3), hardening step device is whole along being arranged on ground slide rail, does a to-and-fro movement, makes quenching workpiece motion on perpendicular to walking dolly direction of motion carry out cooling;
(4), hydro-cylinder drives column in the vertical direction to do a to-and-fro movement, makes the motion of quenching workpiece in the vertical direction carry out cooling;
(5), repeat above-mentioned steps (2), step (3) and step (4) until quench and finish, then make more than column rising is promoted to hardening liquid liquid level by quenching workpiece.
Beneficial effect: quench cooled system of the present invention can make quenching workpiece movement in three directions carry out cooling by hardening step device, the translational speed of quenching workpiece in three directions can be controlled according to the cooling needs of quenching workpiece by hardening step device, the flow velocity of controlling hardening liquid is easier, be conducive to regulate the exchange rate between quenching workpiece and hardening liquid, make quenching workpiece cooling more even, and be convenient to control the speed of cooling of quenching workpiece.
Accompanying drawing explanation
