Problems solved by technology
This method can effectively reduce internal stress and prevent deformation and cracking. At present, due to its special quenching process, most enterprises still use manual and experienced masters to operate, especially the time limit of the workpiece in salt bath and alkali bath. It is often difficult to grasp and cannot achieve mass production

The invention discloses an automatic graded quenching device. The automatic graded quenching device comprises a base (1) fixed to the hardened ground and a quenching heating box (18), wherein a gradedquenching device body is arranged at the bottom of the base (1); a material distributing device is arranged at the top of the graded quenching device body; the graded quenching device body comprisesa graded quenching box (2); a driving bin (3) is arranged at the bottom of the graded quenching box (2); a screening plate (4) capable of sliding up and down by being attached to the inner wall of thegraded quenching box (2) is arranged in the graded quenching box (2); and a first guide sliding block (5) and a second guide sliding block (6) are fixedly mounted at the two ends of the lower bottomface of the screening plate (4) correspondingly. The automatic graded quenching device is simple in structure and convenient to operate, the purpose of automatic graded quenching can be effectively achieved, and large-batch graded quenching operation is facilitated.
Description
technical field [0001] The present invention relates to the technical field related to quenching, in particular to a step quenching device. Background technique [0002] Since austenite has a higher density than martensite, austenite has a face-centered cubic structure, while martensite has a supersaturated body-centered tetragonal structure, so thermal stress and Phase transformation stress The internal stress generated by the volume change from austenite to martensite is the phase transformation stress, which leads to cracks and cracks in the workpiece, which is especially serious for workpieces with complex shapes. It is well known that the step quenching method can effectively reduce the transformation cracks in the process. The specific processing technology of the graded quenching method is to put the heated workpiece into the salt bath and alkali bath whose temperature is slightly higher than the martensitic transformation temperature point, and keep it warm for 2-5 ...
