specific Embodiment 1

[0059] The metal base is 6061 aluminum alloy, the reinforcing fiber is steel wire, the diameter of the steel wire is φ1.5mm~φ2.5mm, the product wall thickness is 5mm~10mm, and the outer diameter is 80mm~150mm. The melting points of aluminum alloy and steel are quite different, and a metallurgical bond will be formed during the rolling process, which is more closely bonded, has good process performance, and has higher specific stiffness and specific strength. Figure 6 It is a cross-sectional schematic diagram of the product. The reinforcing fiber 101 is steel wire, and the metal base 102 is 6061 aluminum alloy. Since the diameter of the selected steel wire is small, the strength of the pipe can be greatly strengthened by using three fibers, and the pipe can be strengthened as much as possible in a limited space.

[0060] S1. Pickling the steel wire before rolling to remove impurities such as surface oxides, select three constraining blocks 13 with holes slightly larger than the...

[0067] The metal base is copper, the reinforcing fiber is graphite fiber, the graphite fiber diameter is φ1mm~φ3mm, the product wall thickness is 5mm~10mm, and the outer diameter is 80mm~160mm. Graphite fiber has the characteristics of high melting point, good conductivity and high toughness. It is spirally wound in the seamless copper tube, which reduces the weight of the copper tube and maintains the conductivity of the copper tube. It is used in some applications that require light weight and good conductivity. occasion. Such as Figure 7 As shown, it is a cross-sectional view of the product, the reinforcing fiber 101 is graphite fiber, and the metal matrix 102 is copper.

[0068] S1. Before rolling, the graphite fiber is degummed at a temperature of 560°C for 30 minutes at a high temperature, and the constraining block 13 with a single hole and a hole diameter slightly larger than the graphite fiber is selected and the constraining block 13 is installed, and then a graphi...

specific Embodiment 3

[0075]The metal base 102 is made of 6061 aluminum alloy, the reinforcing fiber 101 is made of silicon carbide fiber, the diameter of the silicon carbide fiber is φ2mm-5mm, the wall thickness of the product is 6mm-15mm, and the outer diameter is 80mm-150mm. Silicon carbide fiber has high axial tensile strength, and due to helical winding, it can greatly enhance the torsional strength of the pipe. Such as Figure 8 As shown, the reinforcing fiber 101 is silicon carbide fiber, and the metal base 102 is 6061 aluminum alloy. The helix angle in the production process is minimized, and the axial direction of the fiber coincides with the circumferential direction of the pipe as much as possible. At this time, the force F1 on the fiber is along the fiber axis, and the component force F1y in the direction of the F1y axis cancels out the torsional force. Because its helix angle is very small, F1x is very small, and F1y is almost the same size as F1, which makes better use of its axis. T...

Abstract

The invention provides a flexible forming device for producing a seamless fiber-reinforced metal-based composite tube. The flexible forming device comprises a wire feeding rack, an arc-shaped guide plate, a tensioning wheel, a roller, a conveying roller, a steel ladle, a tundish, a flow diverter, a flow distributor and a constraint block. The invention further provides a flexible forming method for producing the seamless fiber-reinforced metal-based composite tube. The flexible forming method comprises the steps that a reinforcing fiber coil is mounted on the roller, one ends of reinforcing fibers pass through the arc-shaped guide plate along the conveying roller, penetrate through the tundish, and then penetrate through the flow distributor on the low part to extend to a metal rolling area, and the fiber-reinforced composite tube is formed along with rolling of a casting rolling mill. According to the flexible forming device and method, the characteristic that the casting rolling millcan produce tube materials with different hole diameters and wall thicknesses is exerted, meanwhile, the flexible forming device and method have the advantage that the sizes, types and numbers of thereinforcing fibers are conveniently replaced, the production process is simplified, the production efficiency is improved, the metal utilizing rate is increased, and product diversity is increased.

Description

technical field [0001] The invention relates to the field of composite material processing, in particular to a flexible forming device and method for producing seamless fiber-reinforced metal matrix composite pipes. Background technique [0002] Composite materials are new materials formed by people using two or more materials with different properties to optimize the combination. Fiber reinforcement is a new type of material with high strength performance that uses a certain material as the base material and adds reinforcing materials to it. [0003] Now there is a kind of reinforced pipe in the market, which is to enhance the performance of the pipe by adding other dielectric materials to the pipe wall of raw rubber and PVC pipes. The pipe reinforced with spiral wire not only maintains a relatively light weight, but also absorbs the advantages of high metal strength, and has better performance. There is also a fiber-reinforced metal sheet, in which network-shaped reinfor...
