Description
Art
The present invention relates to a kind of quenching unit, the detection of a kind of band and the die press quenching machine tool of age of a draught animal stopping means.
Background technology
For the high-volume course of processing needs to carry out the cover parts of Quenching Treatment, quenching heat treatment is to determine product quality, one of the critical process in serviceability and life-span, quenching heat treatment operation belongs to hot-working, unpredictable factor is a lot, if the Internal and external cycle of railway bearing is during processing and manufacturing, qualified product is processed before operation, in quenching process, through long-time at elevated temperature, cooling rapidly during quenching, inevitably produce physical dimension and the change of shape, when deflection is excessive, substantial amounts of defective work will be produced, rework rate and percent defective are the highest.
At present for the heat treatment general die quenching special purpose machine tool of high-volume cover parts, it is quenched in press in the cooling procedure of part, the quenching mould being suitable for is used can effectively to stop part to shrink, Reducing distortion, it is ensured that the thermal treatment quality of workpiece and dimensionally stable.
All railway bearing die quenching presses of current domestic online use, mainly control overcoat workpiece deflection of raceway in quenching process, the age of a draught animal refers to the ring part that railway bearing overcoat end walls is relatively thin, a kind of reasonably mechanism of the deformation of the age of a draught animal effectively controls, start to shrink at after workpiece quickly cools down in quenching process and hold mould tightly, due to thinner thickness at the age of a draught animal, first shrink and put in place, workpiece raceway and middle part is thicker does not seals, may proceed to contract, in the contraction process of this part, the age of a draught animal outer bulging deformation in various degree can be caused, the deflection causing age of a draught animal part is uncontrollable.
Being raceway due to the manufacturing procedure after traditional quenching i.e. grinding and the age of a draught animal is operation break-down processing, can make up the age of a draught animal deforms the deficiency brought more greatly, but owing to needs are installed for twice and process, working (machining) efficiency is low.Universal and the raising of automaticity manufactured along with enterprise intelligentization, each railway bearing manufacturer uses raceway and the intelligent grinding machine of grinding of the age of a draught animal to overcoat workpiece, if the deflection of the age of a draught animal is excessive, and and the concentricity of raceway can not matched, bring the biggest problem will to disposable grinding, problems with can be produced: 1, the age of a draught animal or ball race grinding are not in place；2, relatively big due to age of a draught animal deformation, excessive in the change of the grinding process medium plain emery wheel depth of cut, make reduce rapidly or damage the service life of emery wheel；3, stock removal is uneven, and percent defective increases, and has a strong impact on production efficiency and the economic benefit of enterprise, and there is certain potential safety hazard.
And railway bearing die quenching press actually used during, overcoat workpiece sometimes has the situation of de-not die sinking after having quenched and occurs, i.e. workpiece and mould the most thoroughly separates.According to equipment die structural analysis, the situation of de-not die sinking has three kinds: one and is workpiece and upper/lower die is all not separated by, and now master cylinder rises and is obstructed, if if dynamic crossbeam is not subjected to displacement after 3-5 second, control system can send displacement delayed alarm；Two is workpiece and lower mold adhesion, and in this case, during discharging, input and output material mechanical hand can send crawl delayed alarm, if mechanical hand does not rise after i.e. 3-5 second, illustrates that workpiece and lower mold do not disengage；Three is workpiece and mold adhesion, this situation there is presently no preventive means and warning function, owing to whole quenching process is to carry out in the environment closed, therefore, this phenomenon is not easy to be found by operator, if workpiece adheres to the most not be found, after the red heat workpiece of next one circulation puts in place, dynamic crossbeam still can decline automatically, causes the badly damaged of workpiece or even equipment, directly influences production efficiency and the economic benefit of enterprise.

This device work process is as follows:
1, in the sleeve workpiece mold by feed mechanism amplifier to workbench, after workbench runs the quenching position supreme, lower mold is coaxial；
2, master cylinder is received programmed instruction and is driven dynamic crossbeam, quenching oil cover, mold etc. to decline together, after making the quenching position of the inner hole of workpiece that mold inserts red heat；Quenching position is that upper and lower quenching mould contacts with the inner headed face being quenched workpiece, and it is concentric with the inner circle being quenched workpiece to make upper and lower mould, to reduce the radial deformation during workpiece quenching.
3, in quenching oil cover, quenching coolant is filled, start to shrink at after workpiece quickly cools down and hold mould tightly, due to thinner thickness at the age of a draught animal, first shrink and put in place, now lower mold oil cylinder and mold oil cylinder move the most up and down, ring-type inner cone is driven to move the most up and down, limited block radial contraction is promoted by taper seat thereon, the age of a draught animal external diameter in the cambered surface workpiece on limited block is made to hold tightly, limit its deformation in quenching, it is ensured that concordance that the age of a draught animal and raceway deform in quenching process and controllability；
4, after quenching terminates, lower mold oil cylinder and mold oil cylinder drive respectively ring-type inner cone separately down with on to movement, limited block pilot hole footpath along upper and lower limited block guide holder under the elastic force effect of spring is displaced outwardly, workpiece is unclamped, moving beam is upwards simultaneously, drive the quenching oil cover being arranged on moving beam and mold to rise to upper, treat that subsequent cycle quenches；
5, there will be following four situation after having quenched:
1) if workpiece and upper and lower mould thoroughly separate, equipment runs the most automatically；
2) if workpiece and upper and lower mould are all not separated by, equipment master cylinder system has delayed alarm function；
3) if workpiece and lower mold are not separated by, in equipment go merely arm-and-hand system without material desirable, arm-and-hand system delayed alarm；
4) if workpiece and mold are not separated by, detection air cylinder driven piston rod and detecting head are moved to the left and detect through the hole on quenching oil cover, if mold does not has workpiece, have after the hole that piston rod in cylinder passes moves into place on detection cylinder quenching oil cover with mold correspondence position, magnetic switch is connected, illustrate that the location of workpiece is normal, detecting head return.If mold and workpiece adhesion; detection cylinder location switch is obstructed; illustrate that the location of workpiece is abnormal; workpiece detecting head time delay return; system sends workpiece dystopy alarm signal, and equipment carries out the secondary demoulding automatically simultaneously, if the secondary demoulding is the most unsuccessful; system sends sound and light alarm signal autostop again, reminds such accident of operator's artificial treatment.
