Problems solved by technology
However, the large amount of deformation, insufficient toughness, and serious decarburization caused by conventional quenching are difficult to meet the requirements of high-speed looms.
The technical difficulty of the heat treatment of the reading arm The hardness difference between the hardened area and the base area is large, there is no obvious transition area between the two areas, and the stress generated under the working load cannot be released, which will have a certain impact on the service life of the reading arm

Embodiment Construction
[0013] Such as figure 1 , figure 2 As shown, the sensor of the reading arm in the electronic dobby shedding device of the high-speed loom includes a conductive plate 1 , a bus 2 and an induction coil 3 . The surface of the confluence pipe 2 is provided with insulating bakelite, one end of the confluence pipe 2 is fixedly connected with the conductive plate 1 through bolts, and the other end of the confluence pipe 2 is provided with an induction coil 3 . The induction coil 3 is provided with a nozzle 4 .
[0014] The induction coil 3 is an arc-shaped pure copper tube.
[0015] In order to make the liquid spray uniform, six nozzles 4 are equally divided and symmetrically distributed on the induction coil 3 .
[0016] To design the size of the induction coil, the size design of the induction coil must consider the following aspects:
[0017] (1) The material, size, shape and structural characteristics of the quenched parts;
[0018] (2) Parameter indicators such as frequenc...

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 [0001] The invention relates to an inductor, in particular to an inductor for a reading arm in an electronic multi-arm shedding device of a high-speed loom, and belongs to the technical field of thermal processing of components in textile machinery. Background technique [0002] China is a big country in the textile industry. Especially since the 21st century, China's textile machinery industry has developed relatively rapidly. Both the scale of the textile industry and the output of textiles rank first in the world. With the high-speed development of my country's textile machinery in recent years, the requirements for the mechanical properties of parts are getting higher and higher, especially the service life of the reading arm in the electronic dobby shedding device of high-speed looms is higher. The reading arm part is a typical transmission structure in the electronic multi-arm shedding device for textile machinery, with a thickness of 3mm and belongs to...
