Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof.

The prestressed wire-wound frame has problems in that: the use of steel wire as the wrap reinforcement results in an excessively heavy wrap frame that is difficult to move.

The carbon fiber is a new material with excellent mechanical property, the specific gravity of the carbon fiber is less than 1/4 of steel, and the tensile strength of the carbon fiber can reach 7-9 times of that of the steel. Carbon fibers have been widely used in the high-tech fields of aviation, aerospace, military and civil use, and are superior to steel wires in both performance and lightweight.

The utility model aims to provide a prestressed carbon fiber winding press frame by adopting carbon fibers as winding reinforcing materials. As shown in fig. 1 to 3, the prestressed carbon fiber winding press frame provided by the embodiment of the present invention includes an upper semicircular beam 1, a lower semicircular beam 2, a first column support plate 3, a second column support plate 4, and carbon fibers 5, wherein:

the first and second

column support plates

3 and 4 are connected side by side between the upper and lower

semicircular beams

1 and 2. The outer side surfaces of the upper semicircular beam 1, the lower semicircular beam 2, the first upright support plate 3 and the second upright support plate 4 surround to form a closed winding support surface.

The carbon fibers 5 are wound on the winding support surface to form a carbon fiber winding reinforcement layer having a predetermined thickness. And the specific thickness value of the carbon fiber winding reinforcing layer is selected and set according to actual needs.

The prestressed carbon fiber winding press frame provided by the utility model adopts carbon fibers as winding reinforcing materials, so that the weight of the press frame can be greatly reduced.

The carbon fiber 5 may be carbon fiber precursor, or carbon fiber unidirectional cloth or carbon fiber narrow-band cloth made of carbon fiber precursor.

Alternatively, a dense carbon fiber wound reinforcement layer is formed in close association with the winding support surface in order to solidify the carbon fibers 5 on the winding support surface. The curing agent is continuously coated on the carbon fibers 5 in the process of winding the carbon fibers 5 around the winding support surface. After the carbon fiber 5 is wound, a carbon fiber winding reinforcing layer tightly combined with the winding supporting surface is finally formed along with the curing of the curing agent.

Of course, in order to improve the curing effect, after the carbon fibers 5 are wound, the press frame may be placed in a vacuum furnace to perform curing, or a mold may be used to perform pressurized anaerobic curing, etc.

Optionally, the curing agent is a thermosetting resin curing agent.

With continued reference to fig. 1 to 3, optionally, the prestressed carbon fiber winding press frame in the embodiment of the present invention further includes two upper filament baffles 6 disposed on two sides of the upper semicircular beam 1, two lower filament baffles 7 disposed on two sides of the lower semicircular beam 2, two first vertical filament baffles 8 disposed on two sides of the first column supporting plate 3, and two second vertical filament baffles 9 disposed on two sides of the second column supporting plate 4.

Wherein, two upper filament baffles 6 all extend outside the outside surface of upper semicircular beam 1, so, twine the carbon fiber 5 on the outside surface of upper semicircular beam 1 and be limited in between two upper filament baffles 6. The two lower filament guard plates 7 extend outward beyond the outer side surface of the lower semicircular beam, so that the carbon fibers 5 wound on the outer side surface of the lower semicircular beam 2 are confined between the two lower filament guard plates 7. The two first upright wire blocking plates 8 both extend outwards beyond the outer side surface of the first column support plate 3, so that the carbon fibers 5 wound on the outer side surface of the first column support plate 3 are confined between the two first upright wire blocking plates 8. The two second upright wire blocking plates 9 each extend outward beyond the outer side surface of the second pillar support plate 4, and thus the carbon fibers 5 wound on the outer side surface of the second pillar support plate 4 are confined between the two second upright wire blocking plates 9.

Optionally, the upper wire baffle 6 is semicircular, and the lower wire baffle 7 is rectangular.
