Description
Technical field
This utility model device is a kind of device of quenching, particularly for the high-low pressure combination water spray of hollow drill rod quenching
Device.
Background technology
During drill steel high-volume is using mining at home, drill steel is consumable accessory product, and long-term operation medium is ore deposit
Stone, roadbed, concrete, ship, slag etc., therefore the tip of drill steel can wear and tear in the course of the work, in the ineffectiveness analysis of drill steel
On the basis of, under conditions of not changing drill steel profile, improving drill steel surface quality and be even more important, traditional quenching mode has oozes
Carbon, sensing heating, current sensing heating is widely used with its unique advantage, but cooling water is carried out after sensing heating and is entered
During row cooling, it is larger that stress easily occurs in surface, embrittlement phenomenon, and internal zone of heating poor quality occurs, therefore after quenching
Hollow drill rod surface quality effect on driving birds is not good, do not significantly improve.
The content of the invention
Not enough for more than, this utility model device provides a kind of high-low pressure combination water spray for hollow drill rod quenching
Device.
This utility model device mainly includes rotating lifting gear, low pressure and mass flow water spray box, high-pressure low-flow nozzle, circle
Type induction apparatuss, hollow drill rod is fixed on the rotating lifting gear of bottom, and hollow drill rod upper outer is provided with round induction apparatuss,
Round induction apparatuss lower section is arranged on high-pressure low-flow nozzle, and high-pressure low-flow nozzle lower section is dispersed with low pressure and mass flow water spray box,
Low pressure and mass flow water spray box inner side is uniform-distribution with spray orifice, and round induction apparatuss are internally provided with cooling water channel.
This includes following technical scheme using new device：Hollow drill rod is fixed on rotating lifting gear, will be cooled down
Water connects respectively low pressure and mass flow water spray box, high-pressure low-flow nozzle, round induction apparatuss, and round induction apparatuss are connected into power supply,
Rotating lifting gear drives hollow drill rod to move and Rotating with Uniform, and the round induction apparatuss of energization pass through electromagnetic induction principle pair
Hollow drill rod surface carries out quickly heating up to needs temperature, moves to after heating at high-pressure low-flow nozzle to the quick cooling in surface
To 500 DEG C or so, high pressure can destroy the steam blanket on test specimen top layer, and low discharge can prevent from affecting internal zone of heating, Ran Houyi
Move at low pressure and mass flow water spray box, sprayed cooling water by spray orifice, surface of test piece is uniformly cooled to 200 DEG C or so, greatly
Flow low pressure can reduce rate of cooling, reduce the stress on test specimen top layer, prevent embrittlement, improve quenching quality.
In the hollow drill rod quenching unit of above-mentioned offer：Round induction apparatuss are made up of hollow red copper square tube, by cooling
Water channel is passed through cooling water.
In the hollow drill rod quenching unit of above-mentioned offer：Round induction apparatuss lower section is sequentially distributed high-pressure low-flow nozzle
And low pressure and mass flow water spray box, round induction apparatuss, high-pressure low-flow nozzle and low pressure and mass flow water spray box be connected with high-low pressure water
Pump.
In the hollow drill rod quenching unit of above-mentioned offer：Hollow drill rod is with rotating lifting gear by being fixedly clamped.
Advantage and good effect that the technical scheme that this utility model device is provided is brought：
Hollow drill rod is quenched by high-low pressure combination water jet, improves internal thermal treatment zone structure property, improved
Quenching quality, while the drawbacks of preventing surface of test piece from embrittlement occurring.

Specific embodiment
In FIG, a kind of high-low pressure combination water jet for hollow drill rod (3) quenching mainly includes rotating lifting gear
(1), low pressure and mass flow water spray box (2), high-pressure low-flow nozzle (4), round induction apparatuss (5), hollow drill rod (3) is fixed on bottom
Rotating lifting gear (1) on, rotating lifting gear (1) drive hollow drill rod (3) Rotating with Uniform movement, on hollow drill rod (3)
Side outside is provided with round induction apparatuss (5), and being passed through power utilization electromagnetic induction principle carries out sensing heating, round sensing to drill steel
Device (5) lower section is arranged on high-pressure low-flow nozzle (4), destroys test specimen top layer steam blanket by high-pressure low-flow nozzle (4), quickly
Cool, high-pressure low-flow nozzle (4) lower section is dispersed with low pressure and mass flow water spray box (2), reduces drill steel skin stress, it is to avoid
Top layer embrittlement, low pressure and mass flow water spray box (2) inner side is uniform-distribution with spray orifice (7), and round induction apparatuss (5) are internally provided with cooling
Water channel (6), by cooling water channel (6) cooling water is passed through, and induction apparatuss are lowered the temperature, and prevents high temperature from affecting the work of induction apparatuss
Make performance.
In implementing shown in Fig. 1 and Fig. 2, hollow drill rod (3) is fixed on rotating lifting gear (1), moisture will be cooled down
Not Lian Jie low pressure and mass flow water spray box (2), high-pressure low-flow nozzle (4), round induction apparatuss (5), and by round induction apparatuss (5) even
Power supply is connect, rotating lifting gear (1) drives hollow drill rod (3) to move and Rotating with Uniform, and the round induction apparatuss (5) of energization lead to
Crossing electromagnetic induction principle and hollow drill rod (3) surface is carried out quickly heating up to needs temperature, and high-pressure low-flow is moved to after heating
Nozzle (4) place is quickly cooled to 500 DEG C or so to surface, and high pressure can destroy the steam blanket on test specimen top layer, low discharge can in case
Internal zone of heating is only affected, low pressure and mass flow water spray box (2) place is then moved to, its inner side is uniform-distribution with spray orifice (7), passes through
The spray orifice (7) that inner side is arranged uniformly sprays cooling water, and surface of test piece is cooled to into 200 DEG C or so, and big flow low pressure can drop
Low rate of cooling, reduces the stress on test specimen top layer, prevents embrittlement, this high-low pressure combination spreader to be avoided that troostite is produced,
And its hardness is improved, and effective depth of hardening is improved, and significantly improves quenching quality.
