JPS6034046Y2 - Channel part of open-end spinning machine - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a channel part of a channel of an open-end spinning machine in which fibers opened by an opening roller are transported to a spinning rotor.

Figure 1 shows spinning unit 1 of an open-end spinning machine.
, and the channel part 2 is removably fitted.

Since the conventional channel part 2 has a complicated shape, it is made of an aluminum alloy with good castability, and its surface is hard alumite treated.

However, Channel Edge 3 of Channel Part 2 is
There was a drawback that abrasion marks 4 were created by the sliding contact of the fibers flying out from the opening roller, and the fibers were caught in the abrasion marks, clogging the channel, and causing flying fibers.

The present invention solves the above-mentioned drawbacks of the conventional channel parts, and creates channels by inserting or removably fitting a wear-resistant metal channel member into a material with a low melting point that is relatively easy to cast. An embodiment of the channel part of an open-end spinning machine according to the present invention will be described below with reference to the drawings.

Embodiment 1 FIGS. 2 and 3 show an embodiment of the channel part of the present invention.

Made of wear-resistant metals such as nitriding steel, tool steel, and high carbon steel.
A groove member 5 having a substantially U-shaped cross section is disposed in the channel part of the channel part as shown in FIG. Channel part 2 of this invention is made by injection molding with synthetic resin such as
Configure.

In addition, the groove member 5 can also be made into a cylindrical shape.

The channel part of this invention has the above-mentioned structure and has high wear resistance, so it lasts for about 3 months to 3 months compared to conventional channel parts.
It can more than double the lifespan of 6 months.

Embodiment 2 Other embodiments of the channel part of the present invention are shown in FIGS. 4 and 5.
As shown in the figure.

The channel part main body 6 is formed by precision casting such as light alloy die casting or lost wax, or by injection molding of synthetic resin. The channel part of the present invention is constructed by removably fitting a cylindrical channel member 7 made of a wear-resistant metal such as carbon steel into the channel part main body 6.

The channel part of the present invention has a long service life because the parts that are subject to significant wear are made of highly wear-resistant metal, and can be replaced when the channel members wear out, making it possible to replace conventional channel parts. This idea has great practical effects, such as being able to reduce costs compared to the alternative.
