Description

Quenching inducer for brake platen cone nest

Technical field

The utility model belongs to induction heat treatment technical field, is related to a kind of quenching sensing for brake platen cone nest Device and adapted method for determining size.

Background technology

It is well known that the braking ability of tractor is the important factor in order for determining production operation safety, with agriculture machine The fast development of tool, domestic and international tractor maximization, intelligentized trend increasingly highlight, and large and middle tractor F-Zero has surpassed 30 kilometers/hour are crossed, is particularly important thus it is guaranteed that tractor braking performance is in safe practice state.

Frictional force between brake platen and friction plate when the factor for directly determining tractor braking performance quality is braking Size, and the coefficient of friction and the pressure born of rubbing surface that the size of frictional force is depended between two rubbing surfaces.Rubbing surface is held The source pressure received is extruded brake platen cone nest in steel ball, if brake platen cone nest intensity is too low, is squeezed with steel ball Worn during pressure friction, then pressure necessarily reduces, so that the frictional force between brake platen and friction plate reduces, cuts Weak braking effect.Therefore, brake platen is the vital part of brake, and its quality directly decides that tractor is using During security.

Fig. 1 is a kind of brake platen schematic diagram of tractor of the prior art.

6 cone nests are uniform-distribution with each brake platen, cone nest bottom is deep, and afterbody is shallow.Braking principle is：Two systems Dynamic device platen is bored and a steel ball is pressed from both sides at nest with respect to thirty years of age, and steel ball bores nest bottoms in two brake platens during tractor normally travel. Now, pressure is not produced between two brake platen back sides and friction plate, also with regard to zerofriction force；It is wrong by external force during braking Brake platen is moved, now steel ball is pushed to shallower cone nest afterbody by deeper cone nest bottom, and two brake platen spacing become Greatly, the back side produces friction with friction plate, so as to reach the effect of braking.

To improve the wearability that platen bores nest, currently used method is as follows：

1st, surface hardening by flame heating.

Surface hardening by flame heating is that one kind is quickly heated workpiece surface with acetylene-oxygen flame, subsequent Liquid injection cooling A kind of method for quenching surface.Its major advantage：Equipment is simple, small investment, cost are low；Do not limited by site environment and workpiece size System, applicability are wide, easy to operate；It is adapted to small lot production.

Although the method be main stream approach at present, the weak point of this method is, the flame heat time, heat away from From, translational speed and with a distance from operator experience manual operations, heating-up temperature, firing rate, heating exact position are difficult to control System, it is impossible to ensure to bore the stability of the quenching quality such as the quenching hardness on nest surface, depth of hardening zone, quenching uniformity, operation is not When even causing cone nest surface part scorification, scrapping for brake platen is caused；It is difficult to mechanization Production line；After quenching Part deformation amount is big, is unfavorable for post-production, assembling.

2nd, laser surface hardening

To solve the problems, such as that surface hardening by flame heating deformation is big, domestic scholars intend the method pair using laser surface hardening Brake platen cone nest carries out surface peening, to obtain required quenching hardness and depth of hardening zone.

Laser surface hardening is that material surface is heated to more than transformation temperature using laser, difficult to understand as material itself cools down Family name's body is changed into martensite, so that the quenching technology of material surface hardened.This technology has that power density is high, cooling rate is fast, no Need the cooling mediums such as water or oil；Case hardness is high；The advantages that workpiece deformation is small.

But the weak point of this method is that depth of hardening zone is shallower, and uneven, ball-and-socket midline is up to 1.2 mm, side Edge position only has 0.2~0.6 mm, does not reach technical requirements；In addition, laser surface hardening equipment is expensive, cost is higher, unfavorable In popularization and application.

3rd, QPQ Quench-Polish-Quench technologies

QPQ Quench-Polish-Quench technologies are based on the technique handled in nitriding salt bath and oxidation salt bath, can be realized simultaneously Nitriding and the Combined Processing of oxidation, diffusion layer organization is the compound nitride and oxide for having high intensity and high corrosion-resistant.

The wearability and corrosion stability of piece surface can be greatly improved using this technology, can solve that there is complexity well The problem of constitutional detail is difficult to strengthen, while this technology also has the advantages that workpiece distortion is small, saves.

But its diffusion layer organization depth is extremely shallow, and the compound layer to play a crucial role, its depth only has 0.03 mm, in big load Easily damaged under percussion.

4th, surface induction hardening

Surface induction hardening is to produce vortex in workpiece using electromagnetic induction and heated workpiece, then carries out table The technology of face quenching, i.e. workpiece is placed on the induction coil of enough power outputs, i.e., in inductor, in high-frequency alternating magnetic field Under effect, workpiece surface forms powerful induced-current, is brought rapidly up workpiece surface, then carries out surface hardening.This skill Art is considered solve above-mentioned insufficient ideal side because the rate of heat addition is fast, it is small to be deformed after heat by numerous scholars and technological staff Method, due to problems be present, though so that but fail to solve to be occurred well so far through repeatedly research trial at present Quenching quality problems.Existing problem is as follows：

1）Inductor profiling is poor.Because brake platen cone nest shape is small and irregular, the making to inductor is brought Very big difficulty, current inductor are mostly yi word pattern, and steamed bread of corn side applies and is covered with magnetic conduction powder, and this inductor profiling is poor, heating Efficiency is low, and micro-structure distribution is uneven.

2）Sensing spacing is difficult to control.Inductor is placed in cone nest during due to heating, viewed from above to be difficult to see that sensing Device bottom from nest bottom with a distance from, if distance the too near easily local scorification in nest bottom, or even occur sparking burn out inductor；If distance Too remote, heating effect is with regard to undesirable, and not only depth of hardening zone is partially shallow, and influences the uniformity of its quenching.
