Description
Technical field
The utility model relates to a kind of a kind of device of electromagnetic induction principle to workpiece induction heating, particularly a kind of load coil for Screw Parts applied.
Background technology
The ball screw that the utility model relates to is that a kind of major axis class is cold rolling or grind Screw Parts, as Fig. 1, is widely used in industrial robot tool equipment.In ball screw production process, induced surface hardening directly control that ball screw surface hardness, case depth, metallographic structure, pitch change and axially, radial deformation etc., be the critical process that affects ball screw grade and mechanical property.
Ball screw heat treatment machine is workpiece movable normally, the horizontal type machine tool that load coil is static, and workpiece rotates in feeding, the method that adopts laser heating to quench.
Load coil is as the terminating unit of induction hardening equipment, it is one of essential core component, ruhmkorff coil design whether rationally, manufacture whether superior, directly affect heats, quenching quality and the production efficiency of quenching workpiece, and induction hardened technical study, improvement and test are all carried out round load coil mostly.The calculating of load coil is very complicated, the coil designing by calculation result often with produce actual having a tremendous difference, so load coil be all design, manufacture, test, improve, test again, improved process again.Structure, shape and quenching position according to workpiece, load coil utilizes in design or overcomes electromagnetic induction, surface action, proximity effect, dough nut effect, sharp angle effect, magnetizer notch effect and thermal conduction, therefore not only suitability is wideless for existing ruhmkorff coil, and production efficiency is low.
Summary of the invention
The purpose of this utility model is, provides a kind of suitability wide, and the high load coil for Screw Parts of production efficiency.
The utility model solves the technical scheme that its technical problem adopts: a kind of load coil for Screw Parts, comprise coil, two omnibus bars, two water coolant boxes, insulating trip, two corresponding settings of omnibus bar, insulating trip is fixed between two omnibus bars, coil has two connecting pins, be connected with two omnibus bars respectively, two water coolant boxes are fixedly installed on respectively the outside of omnibus bar.
Of the present utility modelly further be set to: coil is three circle helical windings, coil hollow, cross section is square tube, the inner side wall thickness of square tube is greater than the thickness on other limits.
Said structure be less than three circle coils and compare, solved in coil intermediate frequency or high-frequency current skew, be heated that part is slow at high-temperature zone heat-up rate, induction heating power power is large and the problem such as rate of heating is slow, identical heating power, rate of heating is doubled, and improves heating efficiency; Be greater than three circle coils and compare, the problems such as hardened-depth is spent deeply, coil rigidity is low have been solved, consider and be heated the wearing and tearing of workpiece side surface to coil internal surface (being gap), coil adopts special-shaped square, that side (inner side) wall thickness that coil vicinity is heated workpiece is thicker, add the refrigerating function of water coolant box, not only suitability is wide but also production efficiency is also high.
Accompanying drawing explanation
Fig. 1 is the sensed heated components schematic diagram in the utility model background technology;
Fig. 2 is the structural representation of the present embodiment;
Fig. 3 is the sectional view of the coil of the present embodiment;
Fig. 4 is coil and the ball screw workpiece assembled sectional view of the present embodiment.
Embodiment
Known with reference to figure 2, Fig. 3, Fig. 4, a kind of load coil for Screw Parts of the utility model, comprise coil 1, two omnibus bars 2, two water coolant boxes 3, insulating trip 4, two corresponding settings of omnibus bar 2, insulating trip 4 is fixed between two omnibus bars 2, coil 1 has two connecting pins, be connected with two omnibus bars 2 respectively, two water coolant boxes 3 are fixedly installed on respectively the outside of omnibus bar 2, coil 1 is three circle helical windings, coil hollow, cross section is square tube, the inner side wall thickness of square tube is greater than the thickness on other limits.
The situations such as the point-like crackle that the utility model considers sparking between workpiece and coil electric discharge, produce while quenching, heating efficiency, the diameter of bore of coil is determined by diameter of work, the relation of the outer diameter D of workpiece and heater coil gap a is as table 1, with the relation of heater coil coil special-shaped square tube length of side c as table 2.
Table 1
Table 2
The front end of omnibus bar 2 connects with the secondary coil of induction hardening transformer, and the position of omnibus bar 2 open holess is determined by induction hardening transformer; A part for rear end and coil 1 is firmly connected together with the weldering of red copper welding rod; In the middle of omnibus bar 2, with teflon insulation plate (insulating trip), separates, make electric current formation loop, the size of insulcrete is a bit larger tham the size of omnibus bar 2, thickness be 2 millimeters the most suitable.
On water coolant box 3, weld warter connection 31, this is water coolant gangway, then the two is welded on omnibus bar 2 and forms water cavity, cooling omnibus bar 2, and omnibus bar 2 need to be used screw rod, insulation spacer, plain cushion, compression spring, fitting nut clamps; Screw rod, plain cushion, compression spring, fitting nut can adopt the non-magnetic materials such as brass, stainless steel, nylon to make; Insulation spacer adopts polytetrafluoroethylmaterial material to make, and the thickness of its boss should be slightly less than omnibus bar and add insulcrete thickness sum.
Obviously, above-described embodiment is only used to done giving an example is clearly described, and the not restriction to embodiment.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of being extended out thus or change are still in protection domain of the present utility model.
