Problems solved by technology

From the perspective of weight reduction, rigidity improvement and fatigue resistance, the material of the heald frame has been developed from wood to iron, and then to the commonly used aluminum alloy and composite material with better performance: CN104024500A and CN103510235B proposed to provide a heald frame A reinforced structural shaft, but the current high-speed and wide-width looms have progressed to the point that products with a width of more than 4000mm in the length direction must be produced. With the increase in load brought about by the widening, only 1 / 2 more CFRP shafts have been unable to meet higher strength and stiffness requirements. Continuously adding CFRP shafts not only increases the actual cost, but also makes the structure more complex; CN102864551A proposes a method for preparing magnesium alloy heald frames for air-jet looms, which has specific strength, specific The characteristics of high rigidity can avoid the transmission resonance between the heald frame and the loom, but the cost of the magnesium alloy material is too high, and only a small amount of equipment can be used; CN101235569A discloses a heald frame rod with an I-shaped section, which includes two side belts , and the connection between the belt and the heald frame will depend too much on the performance of the structural adhesive

Abstract

The invention discloses a carbon-aluminum composite material harness frame. The carbon-aluminum composite material harness frame comprises harness wires and a rectangular frame composed of two transverse elements and two lateral supporting parts, two mounting rails in parallel with the transverse elements are arranged in the inner cavity of the rectangular frame, the harness wires are mounted between the two mounting rails, and the harness wires are perpendicular to the mounting rails; a reinforcing layer component is arranged on the outer surface of the transverse elements, the reinforcing layer component is composed of 4-10 layers of carbon fiber prepreg layers arranged on the outer surface of the transverse elements in a laminated mode in sequence, and the carbon fiber prepreg layers are formed by winding of carbon fiber prepreg. The carbon-aluminum composite material harness frame has high specific stiffness and good fatigue resistance.

Description

technical field [0001] The invention relates to a heald frame structure used for looms, in particular to a novel structural heald frame integrated with carbon fiber composite material and aluminum alloy material and a method for manufacturing a transverse element. Background technique [0002] As the speed of the loom continues to increase, the width of the loom increases, and the heald frame is subject to increased stress. The heald frame often breaks and falls apart, and needs to be replaced frequently, which reduces work efficiency and increases production costs. Therefore, it is necessary to continuously improve the heald frame. box performance. From the perspective of weight reduction, rigidity improvement and fatigue resistance, the material of the heald frame has been developed from wood to iron, and then to the commonly used aluminum alloy and composite material with better performance: CN104024500A and CN103510235B proposed to provide a heald frame A reinforced str...
