Abstract

The invention provides fastener quenching treatment equipment which comprises a rack, a heating room, a first blanking device, a quenching tank, a cooling spraying device, a conveying device and an air blast drying device, wherein the heating room, the first blanking device, the quenching tank and a first waste liquid recycling tank are sequentially arranged in the rack from top to bottom; the quenching tank comprises an outer cylinder and an inner cylinder; a distributing mechanism is arranged above the inner cylinder; an accommodating cavity is formed between the outer cylinder and the innercylinder; a second blanking device is mounted at the bottom of the accommodating cavity; a baffle frame used for blocking the bottom of the accommodating cavity is mounted on the second blanking device; the cooling spraying device comprises a plurality of spraying brackets which are circumferentially distributed on the periphery of the quenching tank; the input end of the conveying device is positioned right below the quenching tank; the air-blast drying device is arranged above the output end of the conveying device; and a plurality of air-blast nozzles are uniformly mounted on the air-blastdrying device. The fastener quenching treatment equipment is convenient to operate, good in cooling effect and high in quenching efficiency.

Description

【Technical field】 [0001] The invention relates to the technical field of fastener production equipment, in particular to fastener quenching treatment equipment. 【Background technique】 [0002] The essence of quenching treatment is to adjust and control the flow rate and temperature of quenching medium through moderate cooling to adjust and control the temperature field, tissue field, stress field and strain field of the quenched workpiece, so that the workpiece can obtain the required structure, performance and small residual stress and residual strain. During the quenching and cooling process, due to the uneven temperature distribution inside the part and the uneven transformation process of the structure, thermal stress and phase transformation stress are formed. The existence of these stresses will directly affect the structure performance and service life of the part. If the heat treatment is not proper, the structure and performance of the parts will not meet the prede...
