Abstract

The invention discloses an oil pipe joint of a numerical control lathe and a thermal treatment process thereof. The oil pipe joint of the numerical control lathe and the thermal treatment process thereof comprise a body and a thermal treatment process, wherein the upper end of the body is provided with a cylindrical structure, the middle part of the body is provided with an outside hexagonal structure, and the lower part of the body is provided with a toothed cylinder structure; the upper part in the body is provided with a cylindrical through hole structure which is arranged to be a first through hole structure, and the lower part of the body is similarly provided with a cylindrical through hole structure which is arranged to be a second through hole structure; the external diameter of the first through hole structure is greater than that of the second through hole structure; the thermal treatment process of the oil pipe joint is characterized in that the oil pipe joint is immersed into a proper quenching medium to cool at a higher speed after being heated to be austenitized. The oil pipe joint has high enough tensile strength to resist stretch, snap, slipping and wear, has higher fatigue resistance and impact toughness, can resist fatigue and impact fracture and can be excellently applied to the numerical control lathe.

A kind of numerically controlled lathe oil connection and heat treatment process thereof
Technical field
The present invention relates to a kind of engineering goods, specifically a kind of numerically controlled lathe oil connection and heat treatment process thereof.
Background technique
Some numerically controlled lathe oil connections 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 connection and heat treatment process thereof.
The object of the invention is to solve more existing numerically controlled lathe oil connections, there is no sufficiently high tensile strength, elongation cannot be resisted, break, slide fastener and wearing and tearing, and fatigue resistance and impact toughness also not high enough, cannot resisting fatigue and impact fracture, well can not 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 connection and heat treatment process thereof, comprise body and heat treated process, its upper end of described body is set to cylindrical structure, outer-hexagonal shape structure is set in the middle of it, tooth shape cylinder body structure is set to below it, described body middle upper portion is set to tubular through-hole structure, be set to the first through-hole structure, its underpart is set to tubular through-hole structure equally, be set to the second through-hole structure, the external diameter of its first through-hole structure is greater than the second through-hole structure, its heat treatment process feature immerses after being heated to austenitizing in suitable quenching medium with speed cooling faster.
Described heat treatment process, when selective quenching medium, first should ensure enough cooling capacities, namely 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, slide fastener and wearing and tearing, and has higher fatigue resistance and impact toughness, can resisting fatigue and impact fracture, can well apply in numerically controlled lathe.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is plan view of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
