Abstract
The invention discloses a bolt of an oil circuit of a numerical-control lathe and a process for thermally treating the bolt. The bolt comprises a body. The process includes a procedure for thermally treating the bolt. An externally threaded structure is arranged at the upper end of the body, an outer hexagonal structure is arranged at the lower end of the body, a cylindrical through hole structure is arranged in the middle of the body, a through hole is formed in the middle of each surface of the outer hexagonal structure, and the through holes in the middles of the surfaces of the outer hexagonal structure include a first through hole, a second through hole, a third through hole, a fourth through hole, a fifth through hole and a sixth through hole. The process for thermally treating the bolt is characterized in that the bolt is heated until the temperature of the bolt reaches an austenitizing temperature, and then is immersed in appropriate quenching media to be cooled at a high speed. The bolt and the process have the advantages that the bolt is sufficiently high in tensile strength, can resist stretching, snapping, thread slipping, abrasion, fatigue and impact fracture, is high in fatigue resistance and impact toughness and can be effectively applied to the numerical-control lathe.
Description
Technical field
The present invention relates to a kind of engineering goods, is a kind of numerically controlled lathe oil circuit bolt and heat treatment process thereof specifically.
Background technique
Some numerically controlled lathe oil circuit bolts on existing market, cannot resist elongation, break, slide fastener and wearing and tearing, and fatigue resistance and impact toughness also not high enough, cannot resisting fatigue and impact fracture, can not well apply in numerically controlled lathe.
Summary of the invention
The invention provides a kind of numerically controlled lathe oil circuit bolt and heat treatment process thereof.
The object of the invention is to solve more existing numerically controlled lathe oil circuit bolts, there is no sufficiently high tensile strength, cannot resist elongation, break, slide fastener and wearing and tearing, and fatigue resistance and impact toughness also not high enough, cannot resisting fatigue and impact fracture, can not well apply to the problem in numerically controlled lathe.
The technical solution adopted for the present invention to solve the technical problems is: a kind of numerically controlled lathe oil circuit bolt and heat treatment process thereof, comprise body and heat treated process, its upper end of described body is made as external thread structure, its lower end is made as outer-hexagonal shape structure, in the middle of described body, be made as columniform through-hole structure, the centre of each face of described outer-hexagonal structure is provided with a through hole, be respectively the first through hole, the second through hole, third through-hole, fourth hole, fifth hole and the 6th through hole, its heat treatment process feature is after being heated to austenitizing, to immerse in suitable quenching medium so that speed is cooling faster.
Described heat treatment process, when selective quenching medium, first should guarantee enough cooling capacities, selects the quenching medium that cooling capacity is high, also should prevent distortion and hardening break.
The present invention has sufficiently high tensile strength, to resist elongation, breaks, and slide fastener and wearing and tearing, and have higher fatigue resistance and impact toughness, can resisting fatigue and impact fracture, can well apply in numerically controlled lathe.
