The invention belongs to the technical field of
quenching equipment, and particularly relates to
metal quenching equipment for
metal heat treatment. The
metal quenching equipment comprises a quenching
machine seat, wherein a plurality of quenching cooling seats which are symmetrical along the
central line of the quenching
machine seat are arranged on the quenching
machine seat; metal induction quenching pieces are arranged in the quenching cooling seats; a middle mounting plate is further arranged on the quenching machine seat; and a plurality of metal clamping portions which are symmetrical along the
central line of the middle mounting plate are arranged on the middle mounting plate. According to the metal quenching equipment, an elastic limiting clamping
assembly is arranged, so that in a heat treatment process, the elastic limiting clamping
assembly can clamp and fix an un-clamped end of a
steel tube, synchronously rotates with the
steel tube along with heat treatment, and does not interfere with a quenching process, so that stability of the
steel tube during quenching is kept, angle deviation of the steel tube in the quenching process is avoided, and quenching uniformity and effect are improved; and moreover, the elastic limiting clamping
assembly can be suitable for steel tubes with different diameters, is relatively good in positioning and clamping effect, and is relatively high in practicability.
