Summary of the invention the object of the present invention is to provide the high-frequency quenching mechanism of the cold transverse feed of induction heating limit, a kind of limit speed.The present invention mainly includes induction coil, roller, compactor and thimble.Wherein induction coil has two side faces that are nested together to be provided with the cylinder of axially open, the opening two ends of this inner/outer tube link to each other with two connecting plates respectively, be the corresponding opening of inner/outer tube with linking to each other with a connecting plate, this two connecting plates extend outwards, respectively be located at lathe on tuner link to each other.Be provided with the annulus that opening is arranged that both folded gaps are sealed at the two ends of above-mentioned inner/outer tube.Above-mentioned urceolus is that bus is the straight tube of collinear, and inner core is that bus is the straight tube and truncated cone tube of broken line, and frusto-conical surface is provided with some through holes, i.e. fluid hole.Be provided with fluid inlet in addition on wall of the outer-rotor, it is preferably 1-4.Be provided with two pairs of slick rollers in the induction coil both sides of above-mentioned axis horizontal setting, their axis is all parallel with the axis of induction coil, minimum clearance is less than processed little shaft diameter between every pair roller, so that little axle is placed on the gap of two rollers, be positioned at little its axis of axle and induction coil inner core axis coaxle on two roller gaps simultaneously.Above-mentionedly drive homodromal roller by adjustable frequency motor and can order about little axle and rotate, above little axle, be provided with the compactor corresponding in addition with it, this compactor lower end establish can with the roller or the pressing plate that are coupling for a short time and touch, this roller or be provided with spring above the pressing plate, the upper end of this spring are located on the support above the lathe.The wheel shaft of above-mentioned two pair rollers is located on the bearing support, and this bearing support is located on the cross slide way of lathe, and roller can laterally be moved, and to adjust the spacing of two pair rollers, makes it the length less than workpiece.The above-mentioned roller that is equipped with little axle, its a pair of rear portion is provided with the thimble that promotes little axle axial advancement and pass induction coil, this thimble is located on the slide plate that has guide pin bushing, and this slide plate links to each other with ball-screw again, this ball-screw with link to each other by monolithic processor controlled servomotor.
Working process of the present invention is as follows substantially: little axle is placed between the pair roller (rear roller) of thimble one side and the compactor position.Little axle rotation under the drive of rear roller, it is moving that the thimble of simultaneously little axle back promotes little axial advancement again, be introduced into the straight drum part of induction coil inner core, sensed heating, move forward to inner core truncated cone tube part again, fluid hole on it then just has been heated part spray cooling fluid to little axle, and little axle is quenched herein.So little axle by after finish quenching when advancing forward.Little axle when quenching ceaselessly by the back to reach, the little shaft length that is positioned on the rear roller group is shortened gradually, and little axle front end is inserted between another pair roller (front wheel) and the compactor after passing induction coil, with little axle location.Little axle is located by the front wheel group fully when little axle breaks away from the rear roller group, thereby has guaranteed that little axis is coaxial with induction coil all the time.
The present invention compared with prior art has following advantage:
1, it is promptly fast cold that the present invention can make each heating back of workpiece, guaranteed that the initial temperature of quenching of workpiece each several part is identical, thereby guaranteed workpiece quenching quality.
2, workpiece is from the induction coil quenching of coming out promptly to finish, high efficiency.
3, the quenching workpiece does not need to be installed, and only by thimble workpiece is delivered to induction coil and gets final product, and is simple to operate, shortens process period.
Embodiment is in the synoptic diagram of the high-frequency quenching mechanism of transverse feed illustrated in figures 1 and 2, induction coil 1 has two side faces that are nested together to be provided with the cylinder 2,3 of axially open, the opening two ends of this inner/outer tube link to each other with two connecting plates 4 respectively, be that the corresponding opening of inner/outer tube is with linking to each other with a connecting plate, this two connecting plates extend outwards, respectively be located at lathe on tuner link to each other.Be provided with the annulus that opening is arranged 5 that both folded gaps are sealed at the two ends of above-mentioned inner/outer tube.Above-mentioned urceolus is that bus is the straight tube of collinear, and inner core is that bus is the straight tube and truncated cone tube of broken line, and frusto-conical surface is provided with some through holes 6, i.e. fluid hole.Be provided with fluid inlet 7 in addition on wall of the outer-rotor, it is two.Be provided with two pairs of slick rollers 8 in the induction coil both sides of above-mentioned axis horizontal setting, as shown in Figure 3, their axis is all parallel with the axis of induction coil, minimum clearance is positioned at little its axis of axle and induction coil inner core axis coaxle on two roller gaps simultaneously less than processed little axle 9 diameters between every pair roller.Above little axle, be provided with the compactor corresponding in addition with it, this compactor lower end establish can with the roller 10 that is coupling for a short time and touches, this is provided with spring 11 above roller, the upper end of this spring is located on the support 12 above the lathe, and this door type support lower end is located on the ball-screw in the two rollers outside.The wheel shaft of above-mentioned two pair rollers is located on the bearing support, and this bearing support is located on the cross slide way of lathe.The above-mentioned roller that is equipped with little axle, its a pair of rear portion is provided with thimble 13, this thimble is located on the slide plate that has guide pin bushing, this slide plate links to each other with ball-screw again, this ball-screw with link to each other by monolithic processor controlled servomotor.
