Abstract
The invention discloses a sensor for a read arm in an electronic multi-arm opening device of a high speed loom. The sensor comprises a conductive plate, a collecting pipe and an induction coil, wherein a bakelite is arranged on the surface of the collecting pipe; one end of the collecting pipe is fixedly connected with the conductive plate through a bolt and the induction coil is arranged at the other end of the collecting pipe; and a nozzle is arranged on the induction coil. The induction coil is a circular-arc-shaped pure copper pipe. The sensor for the read arm in the electronic multi-arm opening device of the high speed loom is simple in structure; high-frequency induction quenching is performed on the working region of the read arm part so that the mechanical properties of the read arm part in the electronic multi-arm opening device of the high speed loom under the working condition can be satisfied; as a result, the working condition requirements of the read arm part are met and the fatigue life of the read arm part is prolonged.
Description
Technical field
The present invention relates to a kind of inductor block, be specifically related to read in the electronic multi-arm opening device of high speed loom the inductor block of arm, belong to the heat processing technique technical field of component in textile manufacturing machine.
Background technology
Since China was a textile industry big country, particularly 21 century, the Field of Textile Machinery Industry development of China was comparatively rapid, was no matter the scale of textile industry or the output of textiles all occupies first place in the world.Towards the development of high speed, also more and more higher to the requirement of the mechanical property of part, require higher the work-ing life of especially reading arm in the electronic multi-arm opening device of high speed loom along with China's textile manufacturing machine in recent years.Reading the arm part is frame typical drive mechanism spare in electronic multi-arm opening device, and thickness is 3mm, belongs to the sheet-type part.As shown in Figure 1, wherein dash area for reading the work area of arm part, claims again the quenched zone, and the eccentric wheel that is GCr15 with material matches, and hardness requirement is 59 ~ 61HRC; White space is matrix, without technical requirements.The heat treating method that used is used is generally conventional quenching and its mechanical property requirement is satisfied in isothermal quenching.And for reading this thin-wall part of arm (thickness be only 3mm), strict control Decarburized layer (being no more than 0.1mm) in use procedure, high (the maximum, force Fmax 〉=7.6KN) of mechanical property requirement.The phenomenon that yet the deflection that brings after conventional quenching is large, toughness is not enough, decarburization is serious is difficult to satisfy the requirement of high speed loom.Read arm heat treated technological difficulties quenched zone and matrix region difference in hardness larger, between two zones, without obvious zone of transition, the stress that produces under operating loading can't discharge, and this can affect to the work-ing life of reading arm.Therefore, need to seek a kind of new thermal treatment unit and satisfy when reading arm part machinery performance, increase the service life.
Summary of the invention
The purpose of this invention is to provide the inductor block of reading arm in a kind of electronic multi-arm opening device of high speed loom, adopt the present invention to carry out hard surfacing and process reading the arm work area, the Hardness Distribution distribution gradient of reading arm can not only be made, and certain zone of transition can also be guaranteed in the quenched zone with between matrix.
The objective 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; The 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 circular-arc pure copper tube.
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 evenly are arranged on induction coil.
The present invention takes the work area high-frequency induction hardening to reading the arm part, satisfies frame with reading the mechanical property of arm part under working condition in electronic multi-arm opening device, satisfies its working condition requirement, extends fatigue lifetime.During use with induction coil along reading arm quenched zone contour direction, Liquid injection cooling 3s after heating, make read the arm surface fully the remaining temperature of cooling rear core take 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 guaranteed to read the arm quenched zone from the surface to the different speed of cooling of core acquisition, the Hardness Distribution distribution gradient of reading arm can not only be made with the good hardness gradient distribution induction heating mode of final assurance, and certain zone of transition can also be guaranteed in the quenched zone with matrix.Reading arm work area is from the stiffness region to the matrix, and hardness is obvious Gradient distribution, and tough ratio is about 4:6, thereby good obdurability proportioning guarantees to read the long life-span of arm part.

In figure: 1 conducting plates, 2 collecting pipes, 3 induction coils, 4 nozzles.
Embodiment
As shown in Figure 1 and Figure 2, read the inductor block of arm in the electronic multi-arm opening device of high speed loom, comprise conducting plates 1, collecting pipe 2 and induction coil 3.Collecting pipe 2 surfaces are provided with bakelite, and collecting pipe 2 one ends are fixedly connected with conducting plates 1 by bolt, and collecting pipe 2 the other ends arrange induction coil 3.Induction coil 3 is provided with nozzle 4.
In order to make hydrojet even, symmetrical 6 nozzles 4 of decile on induction coil 3.
Size to induction coil designs, and the size design of induction coil must be considered the following aspects:
(1) material of quench part, size, shape and structure characteristics etc.;
(2) parameter indexs such as the frequency of high-frequency motor generator, power;
(3) parts quenching method and quenching device situation.
Reading the arm selection is 60Si2mnA, and dimensional thickness is 3mm, and the work area is shaped as circular-arc, and diameter is 61mm; The induction quenching frequency is that 150KHZ, electric current are 0.1KA; Quenching method is taked the heating of 860 ~ 890 ℃ of work areas, 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 to be hard surfacing because read arm, and to read arm thickness be 3mm, according to formula:
