Abstract
The invention discloses an oil-way bolt of a numerically controlled lathe and a thermal treatment process thereof. The oil-way bolt comprises a main body and a thermal treatment process, wherein a toothed cylinder structure is arranged at the upper end of the main body; the middle of the main body is of a cuboid structure; an internal threaded hole is formed in the middle of the cuboid structure; the downside of the main body is of a cylindrical structure; an annular groove is formed in the bottom of the main body; the middle of the main body is of a hollow cylindrical structure. The thermal treatment process is characterized in that after the oil-way bolt is heated to austenitizing temperature, the oil-way bolt is immersed in a proper quenching medium to be cooled at a relatively high speed. The oil-way bolt is high enough in tensile strength, so that extension, breaking, sliding and wearing are resisted; the oil-way bolt is relatively high in fatigue resistance and impact toughness, so that fatigue and impact breaking can be resisted, and the oil-way bolt can be well applied to the numerically controlled lathe.
Description
Technical field
The present invention relates to a kind of engineering goods, specifically a kind of oil circuit bolt of numerically controlled lathe and heat treatment process thereof.
Background technique
The oil circuit bolt of some numerically controlled lathes 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 oil circuit bolt and heat treatment process thereof of numerically controlled lathe.
The object of the invention is the oil circuit bolt solving more existing numerically controlled lathes, 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 oil circuit bolt of numerically controlled lathe and heat treatment process thereof, comprise body and heat treated process, its upper end of described body is set to the cylindrical structure of profile of tooth, cuboid shape structure is set in the middle of it, the centre of described cuboid shape structure is provided with an interior threaded hole, cylindrical structure is set to below described body, an annular groove is provided with bottom it, tubular hollow-core construction is set in the middle of described body, 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:
As shown in the figure, the present invention includes body and heat treated process, its upper end of described body is set to the cylindrical structure 2 of profile of tooth, cuboid shape structure 3 is set in the middle of it, the centre of described cuboid shape structure 3 is provided with an interior threaded hole 6, cylindrical structure 4 is set to below described body, an annular groove 5 is provided with bottom it, be set to tubular hollow-core construction 1 in the middle of described body, 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.
