Abstract

The invention discloses a puncturing and compacting device for carbon fiber three-dimensional fabric forming. The puncturing and compacting device comprises an upper end drive device, a puncturing device and a movable workbench. The upper end drive device drives a small belt wheel through a three-phase asynchronous motor to drive a large belt wheel through a V belt. The large belt wheel is connected with one end of a clutch in a fastened mode. The clutch is in key connection with one end of a crankshaft. The crankshaft is fixed to an upper plate through four bearing seats. A crankshaft connecting rod is fixed to the middle of the crankshaft. The lower end of the crankshaft connecting rod is connected with an upper puncturing plate of the puncturing device through a connecting seat. A puncturing template is driven through rotation of the three-phase asynchronous motor to finish puncturing action. Four polished shafts are sleeved with a movable plate through linear bearings at the four corners, the movable plate is connected with a trapezoidal lead screw through a lead screw nut, and the movable workbench is fixed to the movable plate. The puncturing and compacting device is used for puncturing and compacting of laminated woven carbon cloth, automation of the puncturing, pressurizing and compacting functions of the laminated woven carbon cloth is achieved, working efficiency is improved, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to the technical field of laminated carbon cloth puncturing equipment, in particular to a puncturing and compacting device for forming a carbon fiber three-dimensional fabric. Background technique [0002] Three-dimensional fabric is the fiber reinforced structure with the best performance developed in the past 40 years, and it is mainly used in aviation, aerospace, automobile, medical and new technology fields. The overall puncture technology is a forming technology of three-dimensional fabrics. Its technology adopts the pre-manufactured woven arrangement on the top of the equidistant densely packed Z-direction steel needles. Under the relative movement between the puncture template and the square array of steel needles, the woven fabric is pierced by the steel needles and pushed to the lower end of the steel needles for compaction. After reaching a certain height, the Z-direction fibers will replace the Z-direction steel one by ...
