The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring to fig. 1, the existing carbon fiber jacquard guide bar is formed by pultrusion in one piece, and has fibers in the transverse direction and only resin in the longitudinal direction, so that the strength in the longitudinal direction is insufficient.
The utility model discloses a first refer to and refer to fig. 2-3, a carbon fiber merchant card sley bar, including sley bar main part 1, go up pintle 2, lower pintle 3, sley bar main part 1 is carbon fiber material, goes up pintle 2 and lower pintle 3 and is alloy material, and what use in this embodiment is aluminum alloy material, and aluminum pin axle promptly also can use magnesium alloy material. The upper pin shaft 2 is embedded into the upper part of the guide bar main body 1, the lower part of the upper pin shaft 2 is in the shape of a downward barb, and an upper dovetail groove 4 is formed at the barb; the lower pin shaft 3 is embedded into the lower part of the guide bar main body 1, the shape of the lower pin shaft 3 is an upward barb, and a lower dovetail groove 5 is formed at the barb; the guide bar main body 1, the upper dovetail groove 4 and the lower dovetail groove 5 form a C-shaped structure and can be clamped and installed with a jacquard needle block 6.
The guide bar main body 1 is formed into a strip shape extending along the horizontal direction, and a plurality of upper pin shafts 2 and lower pin shafts 3 are respectively arranged at suitable positions along the length direction of the guide bar main body, so that the upper dovetail groove 4 and the lower dovetail groove 5 can be accurately clamped with the jacquard needle block 6. The number of the upper pins 2 and the lower pins 3 is set in relation to the horizontal direction length of the bar body 1. In this embodiment, the number of the upper pin shafts 2 and the number of the lower pin shafts 3 are four, and the upper pin shafts 2 and the lower pin shafts 3 are arranged in a one-to-one correspondence manner.
The manufacturing method of the first embodiment comprises the following steps: before the carbon fiber jacquard guide bar is not processed, an aluminum pin shaft is embedded in a specific position for forming a dovetail groove, then the whole body is processed to form a structure shown in figure 2, and a dovetail groove shape is processed on the aluminum pin shaft.
When the jacquard needle block 6 is installed, an upper pin shaft 2 and a lower pin shaft 3 which are vertically corresponding are set as a pair of aluminum pin shafts, one jacquard needle block 6 is clamped on the four pairs of aluminum pin shafts, and when the locking device 7 is started, a stress point is transferred to the four pairs of aluminum pin shafts from an original dovetail groove structure.
