Embodiment Construction
[0041] The present invention will be further described in detail below in combination with specific embodiments.
[0042] Such as Figure 1 to Figure 17 As shown, a forming tool with a hole plate sinking for weaving three-dimensional fabrics, including a lower bottom plate 1, an upper bottom plate 2, a blind hole plate 3, a pressure plate 4, a pressure plate reinforcement ring 5, a second hole plate 6 and a first hole The plate 7 and the lower base plate 1 are positioned with the rotary table by the pins of the third mold, and fixedly connected with the disc of the rotary table by bolts, so that the tooling as a whole can rise and fall with the table, move in translation and rotate around its own axis. The upper bottom plate 2 and the lower bottom plate 1 are connected through the linear bearing 10, the linear bearing sleeve 14 and the center sleeve 16 to form a tooling bottom plate; the blind hole plate 3 is positioned with the upper bottom plate 2 through the first mold pin ...

The invention discloses a molding tool with an orifice plate sinking function for knitting a three-dimensional fabric. The molding tool comprises an upper baseplate,a lower baseplate, a pressing plate, a pressing plate reinforcing ring, a cover plate combination and an orifice plate combination; the lower baseplate is installed on a rotating worktable; the upper baseplate is connected with the lower baseplate through linear bearings, linear bearing sleeves and a central sleeve; a blind hole plate is positioned on the upper baseplate through pins and fastened by bolts; the pressing plate reinforcing ring and the pressing plate are fixedly connected and then clamped onto a movable sliding table above the blind hole plate; a second orifice plate is positioned on the pressing plate through pins and fastened by bolts; the second orifice plate is separated from the pressing plate by a sleeve body; a first cover plate and a second cover plate are placed above a carbon rod, and a first orificeplate is connected with the cover plates through orifice plate fixing members; countersinks for installing the linear bearings are machined in the orifice plates, the pressing plate and the cover plates and used for installing the linear bearings, and the plates above are positioned by optical axes to ensure the coaxiality. The molding tool can provide a weft insertion channel for a weft insertion sword of an automatic knitting machine, has an integrated yarn pressing function, improves the production efficiency, reduces the labor intensity and shortens the production cycle.
Description
technical field [0001] The invention relates to the technical field of weaving forming tooling equipment, in particular to a forming tooling with orifice plate sinking for weaving three-dimensional fabrics, which is used in conjunction with an automatic weaving machine. Background technique [0002] Carbon fiber three-dimensional fabric is a new type of composite material that has been born in the past two decades. It is a newcomer in composite materials. It uses three-dimensional overall fabric as a reinforcement. It fundamentally overcomes the shortcomings of low interlayer shear strength and easy delamination of traditional laminates, and has been widely used in aviation, aerospace, military, automotive, medical and advanced sports servers and other fields. However, for a long time, three-dimensional fabrics have been weaved by hand, which makes the forming efficiency of three-dimensional fabrics low, the labor intensity is high, and the product consistency is poor. With...
