Quenching and clamping device for formed sheet metal parts

Abstract

The invention discloses a quenching thermal clamping device for formed sheet metal parts, which is mainly composed of a bracket, a lower mold, an upper mold, a hoisting fixture, a positioning device, a clamping spring, a sleeve and a guide rod; the bracket is fixed by the positioning device in the middle Installed on the quenching liquid tank or on the fixing device near the quenching liquid tank, the four sleeves are fixed on the four corners of the upper end of the bracket, the lower end of the lifting fixture is fixed on the upper surface of the upper die, and the lower end of the guide rod passes through the upper and lower dies The lug is fixedly connected with the nut, the boss on the upper end of the guide rod is set in the sleeve to limit the position, and the clamping spring is sleeved on the guide rod, and is arranged between the lug of the upper die and the boss of the guide rod and is in a compressed state. The present invention can use the existing heating furnace, quenching water tank, quenching high car and other equipment in the heat treatment site to complete the compacting and quenching process, and is suitable for anti-deformation quenching in the small batch production of small bending deformation forming parts, small flat parts and small ribbed parts Production. The structure is simple, the cost is low, and the press quenching effect is good.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a quenching thermal clamping device for formed sheet metal parts. Background technique [0002] The flat plate is formed by stamping to realize the structural shape of the workpiece, and its mechanical properties are improved by heat treatment, which is a common machining method for sheet metal in mechanical products. However, in the process of processing this type of plate shaped parts, quenching deformation is a key factor affecting the processing of this type of workpiece. [0003] Due to the joint action of internal thermal stress and tissue stress during quenching of sheet metal forming parts, large deformation of sheet metal forming parts occurs, and the high hardness and high toughness after quenching make it difficult for the formed parts to restore the original shape through correction. [0004] The press quenching production line is currently a commonly use...
