Embodiment 1

[0037] As shown in the figure, the variable-diameter rotating body acupuncture forming equipment includes a frame, an acupuncture mechanism, a pressure feedback and adjustment device, a mold rotation mechanism, and a mold lifting mechanism;

[0038]The acupuncture mechanism includes a servo motor 1, a pulley set, a main shaft, a pair of outer two-way cams, a pair of inner two-way cams, two inner connecting rods, two outer connecting rods, a needle beam, a profiling needle plate and a profiling stripping board ; The servo motor 1 is fixed on the top of the frame, and the servo motor 1 drives the main shaft to rotate through the pulley set; a pair of outer two-way cams and a pair of inner two-way cams are installed on the main shaft and reciprocate up and down on the main shaft, wherein a pair of inner The two-way cam is located between a pair of outer two-way cams; one pair of inner two-way cams are respectively connected to the needle beam through two inner connecting rods, and...

Embodiment 2

[0044] It is basically the same as Embodiment 1, except that the bevel gear set includes large bevel gears, small bevel gears, small bevel gear connecting shafts and fixed seats; the large bevel gears and the small bevel teeth are meshed at 90°; The bevel tooth connecting shaft is connected with the fixed seat, the small bevel tooth connecting shaft is connected with the servo motor 2, and the fixed seat is fixed on the lifting platform.

Embodiment 3

[0046] It is basically the same as that of Embodiment 1, except that the variable-diameter rotating body acupuncture forming equipment also includes a control system, which includes a man-machine interface, a PLC programmable logic controller, a controller connected to the servo motor, and a The pressure sensor used to detect the pressure realizes the coordinated movement of the acupuncture mechanism, the mold rotation mechanism and the mold lifting mechanism, as well as the closed-loop control of the pressure feedback of the stripping plate.

[0047] Before the needle punching process of the above-mentioned equipment, the unit layer composed of the mesh tire and the base cloth needs to be evenly wrapped on the mold. After the needle punching is completed, the layered layer is wrapped, and the needle punching is continued until the product thickness is finally reached.

[0048] In the production process, the servo motor 1 in the acupuncture mechanism drives the main shaft to ro...

Abstract

The invention discloses variable diameter rotary body fabric needling molding equipment which comprises a rack, a needling mechanism, a pressure feedback and adjusting device, a mold rotation mechanism and a mold lifting mechanism, wherein the needling mechanism, the mold rotation mechanism and the mold lifting mechanism are arranged in sequence from top to bottom; the needling mechanism and the mold lifting mechanism are both arranged on the rack; the mold rotation mechanism is arranged on the mold lifting mechanism and lifted and descended under the driving of the mold lifting mechanism; the pressure feedback and adjusting device is arranged on the needling mechanism. By adopting the variable diameter rotary body fabric needling molding equipment disclosed by the invention, quasi-three dimensional prefabricated body production of a needled fiber multi-layer variable diameter rotary body is achieved, the problems that a conventional operation process is low in production efficiency, high in cost, poor in product quality stability and the like can be solved, on-line pressure monitoring and adjustment of a stripper plate are achieved through the pressure feedback and adjusting device, the density of a needled product is effectively controlled, and high-precision needling molding is achieved; the variable diameter rotary body fabric needling molding equipment is simple in structure, convenient to operate and applicable to industrial production.

Description

technical field [0001] The invention relates to a variable-diameter rotary fabric needle-punching forming device, which belongs to the field of fabric needle-punching forming. Background technique [0002] Acupuncture molding equipment is used to prepare high-performance three-dimensional preforms by laminating and needling multiple fiber layers. Three-dimensional preforms are mainly used in aerospace and other fields. The acupuncture process has the characteristics of fast, efficient and low cost in the preparation of three-dimensional preforms. , has been widely used. At present, acupuncture forming equipment has realized acupuncture forming of specific types of preforms such as flat plates and equal-diameter cylinders. [0003] The flat needle loom is different from the ordinary non-woven needle loom. Although there are great innovations and optimizations in the mechanical structure, it is only used for the needle punching of flat products and cannot realize the forming ...
