Description
Technical field
The present invention relates to a kind of inductor block, be specifically related to the inductor block reading arm in the electronic multi-arm opening device of high speed loom, belong to the heat processing technique technical field of component in textile manufacturing machine.
Background technology
Since China is a textile industry big country, particularly 21 century, the Field of Textile Machinery Industry development of China is comparatively rapid, no matter is that the scale of textile industry or the output of textiles all occupy first place in the world.Along with China's textile manufacturing machine is towards the development of high speed in recent years, also more and more higher to the requirement of the mechanical property of part, the work-ing life of reading arm in the electronic multi-arm opening device of especially high speed loom requires higher.Reading arm part is typical drive mechanism part in frame electronic multi-arm opening device, and thickness is 3mm, belongs to sheet-type part.As shown in Figure 1, wherein dash area is the work area of reading arm part, and also known as quenched zone, the eccentric wheel being GCr15 with material matches, and hardness requirement is 59 ~ 61HRC; White space is matrix, without technical requirements.Past conventional heat treating method is generally conventional quenching and isothermal quenching to meet its mechanical property requirements.And for this thin-wall part of reading arm (thickness is only 3mm), require in use procedure strictly to control Decarburized layer (being no more than 0.1mm), mechanical property requirements high (maximum, force Fmax >=7.6KN).But the phenomenon that the deflection brought after conventional quenching is large, toughness is not enough, decarburization is serious is difficult to the requirement meeting high speed loom.The reading heat treated technological difficulties quenched zone of arm and matrix region difference in hardness are comparatively large, and without obvious zone of transition between two regions, the stress produced under operating loading cannot discharge, and this can affect to the work-ing life of reading arm.Therefore, need to seek while a kind of new thermal treatment unit meets and read arm part machinery performance, to increase the service life.
Summary of the invention
The object of this invention is to provide the inductor block reading arm in a kind of electronic multi-arm opening device of high speed loom, the present invention is adopted to carry out hard surfacing process to reading arm work area, the Hardness Distribution distribution gradient of reading arm can not only be made, and certain zone of transition can also be ensured in quenched zone with between matrix.
The object of the invention is to be achieved through the following technical solutions, read the inductor block of arm in the electronic multi-arm opening device of high speed loom, comprise conducting plates, collecting pipe and induction coil; Collecting pipe surface is provided with bakelite, and collecting pipe one end is fixedly connected with described conducting plates by bolt, and the collecting pipe the other end arranges described induction coil; Described induction coil is provided with nozzle.
Described induction coil is the pure copper tube of arc-shaped.
The effective width of described induction coil, height and length are respectively 8mm, 6mm, 70mm.
The number of described nozzle is 6, and 6 nozzles are evenly arranged on induction coil.
The present invention takes work area high-frequency induction hardening to reading arm part, meets in frame electronic multi-arm opening device and reads the mechanical property of arm part under working condition, meet its working condition requirement, extend fatigue lifetime.During use, arm quenched zone contour direction is read on induction coil edge, Liquid injection cooling 3s after heating, after making to read the surperficial cooling completely of arm, more than core, temperature takes the mode of air cooling.Due to heat conducting effect, the speed of cooling of core is obviously far away faster than normal cooling rate.Such type of cooling ensure that reading arm quenched zone obtains different speed of cooling on surface to core, finally to ensure that good hardness gradient distribution induction heating mode can not only make the Hardness Distribution distribution gradient of reading arm, and certain zone of transition can also be ensured in quenched zone with matrix.Read arm work area from stiffness region to matrix, hardness be obvious Gradient distribution, and tough ratio is about 4:6, good obdurability proportioning thus ensure the life-span that reading arm part is longer.

Fig. 2 is the side-view of inductor block of the present invention;
Fig. 3 is the vertical view of inductor block of the present invention;
In figure: 1 conducting plates, 2 collecting pipes, 3 induction coils, 4 nozzles.
Embodiment
As shown in Figure 1 and Figure 2, in the electronic multi-arm opening device of high speed loom, read the inductor block of arm, comprise conducting plates 1, collecting pipe 2 and induction coil 3.Collecting pipe 2 surface is provided with bakelite, and collecting pipe 2 one end is fixedly connected with conducting plates 1 by bolt, and collecting pipe 2 the other end arranges induction coil 3.Induction coil 3 is provided with nozzle 4.
Induction coil 3 is the pure copper tube of arc-shaped.
In order to make hydrojet even, symmetrical 6 nozzles 4 of decile on induction coil 3.
Design the size of induction coil, the size design of induction coil must consider the following aspects:
(1) material, size, shape and structure feature etc. of quench part;
(2) parameter index such as frequency, power of high-frequency motor generator;
(3) parts quenching method and quenching device situation.
Reading arm selection is 60Si2mnA, and dimensional thickness is 3mm, and work area shape is arc-shaped, and diameter is 61mm; Induction quenching frequency is 150KHZ, electric current is 0.1KA; Quenching method takes the heating of 860 ~ 890 DEG C, work area, Liquid injection cooling after heating.According to above working condition, the principal dimension of induction coil consists predominantly of the length of effect loop diameter, height and inductor block.
1. the width of inductor block coil
Take as hard surfacing because read arm, and reading arm thickness is 3mm, according to formula:
B＝b＋﹙4~10﹚mm
B in formula-inductor block thickness, mm;
B-part thickness, mm.
According to reading arm thickness 3mm, get D=3+5=8mm.
2. inductor block coil height
Read the technical requirements of arm according to Fig. 1, determine that quenched zone size is no more than and read 40% of arm height overall.Reading arm circular arc place height overall is about 10mm, and namely quenched zone size is no more than 4mm, according to formula:

The height of H in formula-induction coil coil, mm;
The height at h-parts quenching position, mm.
In order to obtain good tough proportioning, therefore get H=4+2=6mm.
3. the length of inductor block coil
The length of inductor block coil, to read arm quenched zone length for reference, is finally defined as 70mm.
