Abstract

The invention provides a carbon fiber upper pin assembly adopting pressure bars with a combined structure and a manufacturing method thereof, which relate to the field of textile mechanical components. The carbon fiber upper pin assembly comprises an upper pin frame body, a left tension supporting plate, a right tension supporting plate, a left telescopic spring, a right telescopic spring, spacing blocks, a left pressure bar and a right pressure bar in a front area and one or two pressure bars in a rear area. The left pressure bar and the right pressure bar in the front area adopt a combined structure of elongated metal bars and hollow cylindrical non-metal bars. The pressure bars in the rear area adopt a combined structure of small tubular metal bars and hollow cylindrical non-metal bars. The hollow cylindrical non-metal bars are respectively and tightly sleeved onto the outsides of the elongated metal bars and the small tubular metal bars. A left jaw and a right jaw at the front end of the upper pin frame body are provided with a left ferrule and a right ferrule. Arched cambered surfaces are formed at the front side and the back side of the working surface of the left tension supporting plate and the right tension supporting plate. The left side and the right side of the working surface are also arched. Since non-metal bars are evenly arranged on the surfaces of the front and rear pressure bars, the electrostatic generation can be avoided. Meanwhile, dust cannot be adsorbed. The surfaces of the pressure bars do not need to be finely machined and electroplated, thereby simplifying the machining process and reducing the production cost.

Description

technical field [0001] The invention relates to a carbon fiber upper pin assembly, in particular to a carbon fiber upper pin assembly using a combined structure pressure bar, which is a drafting device for a spinning machine and relates to the field of textile machinery components. Background technique [0002] In the spinning production process, the drafting system of the spinning machine plays a decisive role in the yarn quality. The drafting system of the spinning machine is mainly composed of cradles, rollers, rubber rollers, upper aprons, lower aprons, upper pins, lower pins and other components. The friction formed by the above components during work controls the fiber and The movement between the fibers causes the relative displacement between the fibers in the sliver, and a certain amount of fibers are distributed on a longer segment to achieve the purpose of drafting. The upper and lower pins and the upper and lower aprons form a soft and firm The rubber ring in th...
