Molded sheet metal part quenching and clamping device

Abstract

The invention discloses a molded sheet metal part quenching and clamping device which mainly comprises a bracket, a lower die, an upper die, a hoisting clamp, a positioning device, clamp springs, sleeves and guide rods. The bracket is fixedly mounted on a quenching liquid tank or a fixing device near the quenching liquid tank through the middle positioning device. The four sleeves are fixed to four corners of the upper end of the bracket. The lower end of the hoisting clamp is fixed on the upper surface of the upper die. The lower ends of the guide rods penetrate through support lugs of the upper die and the lower die and are fixedly connected with nuts. Lug bosses at the upper ends of the guide rods are arranged in the sleeves to be spaced. The clamp springs sleeve the guide rods, are arranged between the support lug of the upper die and the lug bosses of the guide rods, and are in the compression state. A pressure quenching process is completed by conventional devices, such as a heating furnace, a quenching water tank and a quenching high car in a heat treatment field, and the quenching and clamping device is suitable for small-batch anti-deformation quenching production of small bending deformation molded parts, small flat workpieces and small swedged plate. The quenching and clamping device is simple in structure, low in cost, and good in pressure quenching effect.

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...
