Problems solved by technology

[0005]1. The yarn feeder handle is steel sheet, the front part is a grooved structure, the yarn feeder head is also a grooved structure, the yarn feeder handle and the yarn feeder head are directly snapped together, because The locking part of the yarn feeder head and the groove of the yarn feeder handle has poor anti-falling ability, and it is easy to fall off when it is under a large force during use, resulting in failures such as scrapping and damage to the machine;
[0006]2. Both the yarn feeder handle and the yarn feeder head are steel castings, connected by springs and pins. This method is reliable in structure, but the material selection of the yarn feeder head is subject to precision The casting process is limited, only alloy steel can be used, the hardness is limited, which affects the wear resistance and the service life is low;
[0007]3. The yarn feeder handle is made of steel sheet, and the yarn feeder head is a precision casting. The connection between the yarn feeder handle and the yarn feeder head is welded by laser. This structure is reliable, but The yarn feeder head also has the problem of low service life. At the same time, the connection method is processed by laser welding, which is costly

Embodiment 1

[0032] Example 1: Making the yarn feeder handle: using an alloy steel sheet with a thickness of 0.7mm, cutting, bending into a yarn feeder handle blank, and then heat-treated to provide strength and elasticity;

[0033] Make the yarn feeder head:

[0034] (1) Mixing: Mix 94% of cemented carbide powder (YG8) and 6% of organic binder evenly to obtain uniform feeding; the proportion of organic binder is 60% of paraffin, 35% of polyethylene, stearin Acid 5%.

[0035] (2) Injection molding: feed the material into the hopper of the injection machine, and mold it at 130-160°C to obtain a blank similar to the shape of the product;

[0036] (3) The blank is pre-sintered while removing the organic binder in the degreasing furnace to obtain a pre-sintered part;

[0037] (4) The pre-sintered parts are sintered in a sintering furnace at 1400°C to obtain yarn feeder products.

[0038] Assembly: Push the yarn feeder head 2 into the yarn feeder handle 1 along the direction of the installa...

Embodiment 2

[0040] Example 2: Making the yarn feeder handle: using an alloy steel sheet with a thickness of 0.8mm, after cutting, bending into a yarn feeder handle blank, and then heat treatment to provide strength and elasticity;

[0041] Make the yarn feeder head:

[0042] (1) Mixing: Mix 85% of ceramic powder (zirconia) and 15% of organic binder to obtain uniform feeding; the proportion of organic binder is 55% of paraffin, 40% of polyethylene, stearic acid 5%.

[0043] (2) Injection molding: feed the material into the hopper of the injection machine, and mold it at 150°C to obtain a blank similar to the shape of the product;

[0044] (3) The blank is pre-sintered while removing the organic binder in the degreasing furnace to obtain a pre-sintered part;

[0045] (4) The pre-sintered part is sintered in a sintering furnace at 1550°C to obtain a yarn feeder product.

[0046] Assembly: Push the yarn feeder head 2 into the yarn feeder handle 1 along the direction of the installation gr...

Abstract

The invention discloses a processing method of a flat knitting machine used yarn feeder and a flat knitting machine used yarn feeder head. The processing method comprises a yarn feeder head and a yarn feeder handle and is characterized in that the yarn feeder handle is form by stamping and bending an alloy steel sheet. The yarn feeder handle is provided with an installing groove which corresponds to the yarn feeder head. The width of the installing groove is slightly smaller the width of the yarn feeder head. The yarn feeder is compulsively pushed into the yarn feeder handle through external force, and the connection of the yarn feeder and the yarn feeder handle is achieved. The yarn feeder head is formed by injection molding of cemented carbide or ceramic material metal. The yarn feeder utilizes hard cemented carbides (ceramics), is high in hardness and good in abrasion resistance. Generally, service life of the yarn feeder is 3 to 4years. The connection structure of the yarn feeder handle and the yarn feeder is reliable, simple and convenient.

Description

technical field [0001] The invention belongs to the field of computerized flat knitting machine components, and in particular relates to a yarn feeder for a flat knitting machine and a processing method for a yarn feeder head. Background technique [0002] The yarn feeder for flat knitting machine is composed of a yarn feeder head and a yarn feeder handle. The function of the yarn feeder head is to provide a channel for the yarn. During the working process, various yarns pass through the holes of the yarn feeder head. The yarn and the yarn feeder head are constantly rubbed against each other. In the end, if the yarn feeder head is ground into grooves by the yarn, the yarn will easily break and the yarn feeder head will be scrapped. Therefore, the yarn feeder head needs higher hardness and is generally made of alloy steel. On the one hand, the yarn feeder handle provides a link for the yarn feeder On the one hand, it is assembled on the seat of Us and moves together to realiz...
