Abstract

The utility model discloses an oil quenching device. The oil quenching device comprises a sealed barrel and a cooling tank containing cooling water, wherein an upper port of the sealed barrel is communicated with a quenching and heating furnace, the lower end of the sealed barrel extends into the cooling tank, a lower port of the sealed barrel is communicated and lower than the liquid level of the cooling water in the cooling tank, quenching oil floating on the cooling water is filled in the sealed barrel, and a slope glider arranged in the quenching oil is arranged on the inner wall of the sealed barrel. According to the oil quenching device and a quenching process thereof, provided by the utility model, the depth of an effective hardened layer of oil quenching is improved, the quenching time and cost are saved, the quenching quality is improved, and the follow-up treatment is facilitated.

Description

A kind of oil quenching device

Technical field

The utility model relates to a kind of quenching device, is that a kind of tempering oil amount is few specifically, and sufficient oil quenching device quenches.

Background technology

Quenching is a kind ofly metal works is heated to a certain proper temperature and keeps for some time, immerse the metal heat treatmet technology of cooling off fast in the quenching media immediately, quenching can improve hardness and the wear resistance of metal works, thereby is widely used in various workers, mould, measurer and requires the part of surface abrasion resistance.Quenching media commonly used has salt solution, water, mineral oil, air etc., wherein the air dielectric cooling power a little less than, only be applicable to that the very low metal works of critical cooling velocity quenches to use that internal stress significantly is lower than other quenchings; The shrend cooling power is stronger, and cooling is fast, but internal stress is big, and yielding, cracking causes workpiece to scrap; And oil quenching has stable cooling, workpiece quenching after strain amount is small, but the oil quenching diameter is little, usually adopt the prolongation oil quenching time to improve the effective depth of hardening of workpiece, prolong the cool time, the quenching cost improves, and the sticking oil in the long-time oil quenching of workpiece surface, when sending into follow-up tempering, the quenching oil loss is bigger, the volatile generation environmental pollution of quenching oil in the tempering; Traditional water quenching workpiece easily forms cracking or deflection is excessive can not satisfy the mechanical technology requirement, reelects the oil quenching mode, and there is sticking oil in the oil quenching product, and oil volatilization, volatilization are not are not checked up and return and will be dried oil, otherwise can bring difficulty to surface treatment during tempering.

Summary of the invention

At the deficiency of oil quenching in the prior art, the utility model provides a kind of can improve the oil quenching effective depth of hardening, saves cool time and cost, improves the quenching quality, is convenient to subsequent disposal, and oil consumption is low, free of contamination oil quenching device and quenching technology thereof.

The technical solution adopted in the utility model is: a kind of oil quenching device, it is characterized in that: comprise envelope bucket and the cooling pool that water coolant is housed, envelope bucket upper port is communicated with the quenching process furnace, envelope bucket lower end is stretched in the cooling pool, seal the connection of bucket lower port and be lower than cooling pool internal cooling water liquid level, be provided with the quenching oil that floats on the water coolant in the envelope bucket, envelope bucket inwall is provided with the gradient glider that places in the quenching oil.

Further, described gradient glider comprises the polylith guide plate, the polylith guide plate is downward-sloping being connected on the envelope bucket inwall successively from top to bottom, the projection of guide plate on envelope bucket radial section is less than envelope bucket radial section, and the side that neighbouring guide plate connects envelope bucket inwall is not in envelope bucket inwall the same side.

Further, described neighbouring guide plate connects the side that the side that seals the bucket inwall is in envelope bucket inwall symmetry respectively.

Further, described cooling pool medium dip arranges a lift, the lower end of lift corresponding envelope bucket lower port, and cooling pool water coolant liquid level is stretched out in the upper end of lift.

Again further, be provided with the guipure of transmission heated parts in the described quenching process furnace, the setting of the terminal corresponding envelope bucket upper port of guipure.

Adopt above technical scheme, the beneficial effect that the utility model reaches is: the workpiece of the heating of quenching directly by the mesh-belt conveying in the quenching process furnace to the envelope bucket, directly enter the oil quenching operation, be convenient to increase work efficiency and guarantee the oil quenching performance; Heated parts falls in the interior quenching oil of envelope bucket, a plurality of guide plates by gradient glider carry out oil quenching, a plurality of guide plate upper and lower settings and connection side symmetry, workpiece drops on the guide plate and is slided by the downward guiding of last guide plate, fallen into down on the guide plate by last guide plate and envelope bucket gap, slided by the downward guiding of following guide plate, workpiece tilts to interlock through a plurality of guide plates successively and leads, prolong the stroke of workpiece in quenching oil, oil quenching is abundant, guarantees that effective depth of hardening reaches the workpiece depth of hardenability, reduces internal stress, the control deflection improves the quality of products; Workpiece falls into the cooling pool water coolant from the quenching oil of gradient glider, and be lifted out the water coolant liquid level by lift from the water coolant lower end, can directly be delivered to follow-up tempering process, further increase work efficiency, be beneficial to crucial follow-up tempering processing, do not have the oil volatilization and pollute, and the quenching oil under cleaning floats in the envelope bucket, recyclable recycling is saved the quenching oil consumption, reduces use cost.

This invention is applicable to soft steel, carbonitriding, and batch workpiece is big, and work efficiency requires high, and deflection requires little or avoids the workpiece quenching of hardening break to use.
