Abstract
The utility model discloses a novel structure inducer which can undertake high-frequency quenching to paper cutting blade or plowshare like products. The traditional high-frequency quenching processes make the cutting edge and cusp point burn out and crack easily and make it difficult to undertake cutting edge surface quenching to the products because of the induction heating cusp effect. The utility model adopts the auger-type structure with magnetic conductor, and this kind of structure avoids the cusp effect effectively and disperses the high-frequency faradic current over the areas the blade required uniformly. The degree of hardness amounts to HRC>63 and the depth of quenching hardening zone is 1.2 mm (knife blade)-2.5 mm (plowshare) measured after quenching. The utility model avoids the superfluous and complicated programs of the paper cutting blade adopting the clad steels (adhesive bonding mixed steels) and the partial salt-bath quenching to the plowshare.
Description
The present invention relates to a kind of improved high-frequency quenching inductor block, particularly a kind of can to like products such as cut paper blade, ploughshare sheet carry out high-frequency quenching the existing scudding knife of novel texture inductor block, tobacco cutter, cut the workpiece of band such as five-ply board cutter, agricultural machinery ploughshare sheet cutting edges, all adopt clad steel (bonding folder steel) or salt bath selective hardening, the cost height, life-span is short, and production efficiency is low.
Traditional quenching technology, be difficult for that the said products is carried out the edge surface quenching and maybe can not reach processing requirement, this mainly is because the sharp angle effect during induction heating, be that magnetic line of force concentrates on the cutting edge edge section, induced current concentrates in the small area, produce high temperature, in moment, make scorification of cutting edge edge or cracking, both made and adopted traditional technological measure, as reduce anode voltage limitedly, shorten heat-up time, increase the gap of inductor block and blade, the hardness of cutting edge also can only reach about the HRC45 degree, and hardness and quenched case are also inhomogeneous, and conventional planar inductor, because of the magnetic line of force of high frequency magnetic field is distributed in the inductor block both sides mostly, make middle portion produce cold zone, thereby influence depth of hardening.If installing magnetizer additional, inductor block can not improve middle cold zone fully.
Task of the present invention is that a kind of improved spiral tight band magnetizer high-frequency inductor will be provided, the scorification phenomenon that it can be avoided sharp angle effect effectively and is caused, eliminate the middle cold zone that is produced with conventional plane quenching inducer, high frequency induction current is evenly distributed on the required area of blade.
Adopt present technique, blade does not need to use steel alloy: 9CrSi, CWMn, GCr15 etc., complicated technology such as weld or bonding, use carbon tool steel T8, T10 to get final product, after tested work-ing life longer by about 45% than clad steel blade, cost descends about 40%, the ploughshare sheet no longer needs salt bath quenching, improve production efficiency, improved Working environment.
The back mensuration hardness of quenching reaches HRC 〉=63 degree.
Depth of hardening 1.2mm (blade)～2.5mm (ploughshare)
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is according to the cut paper blade that the utility model proposes, the front schematic view of ploughshare sheet high-frequency quenching inductor block.
Describe the details and the working condition of the concrete device of the present invention's proposition in detail below in conjunction with accompanying drawing.
The spiral type inductor body (2) that this inductor block is curved by the side's of drawing copper pipe, and comprise two water inlet pipes (1) (5), magnetizer (3), be drilled with many inclinations 45 degree at the edge of inductor block one end and form apart from the spout hole (4) of 1.5mm * 1mm.Inducedmagnetic field during work is by two groups of magnetic conduction district conduction that are installed in sensor wire circle (2) both sides respectively, and water coolant is sprayed from spout hole (4) through sensor wire circle (2) by water inlet pipe (1) (5).
According to above-described device, it is characterized in that sensor wire circle (2) is connected in induction hardening transformer by water inlet pipe (1) (5); Inducedmagnetic field during work collects in the required hardened face of workpiece by magnetizer (3).Continuous when mobile by this inductor block when workpiece, the translational speed of blade is 350 millimeters/minute, and the translational speed of ploughshare sheet is 300 millimeters/minute, through the cooling of spout hole (4) water spray, forms uniform quenched case.
