Abstract
The utility model discloses a plum blossom pipe. The inner wall of the plum blossom pipe is provided with a plurality of arc-shaped protrusions which form reinforcing ribs, and the outer wall of the plum blossom pipe is provided with a plurality of arc-shaped grooves. The plurality of arc-shaped protrusions and the plurality of arc-shaped grooves are evenly located on the walls of the plum blossom pipe in a circumferential array, and the positions of the arc-shaped protrusions correspond to the positions of the arc-shaped grooves. According to the plum blossom pipe, few raw materials are used, the weight of the plum blossom pipe is light, transporting cost can be lowered correspondingly, and adverse impact on the quality of the whole plum blossom pipe cannot happen.
Description
Technical field
A kind of plum tube of the utility model.
Background technique
Existing FRP(Fiber Reinforced Plastics is fiber-reinforced plastic, referring generally to strengthen unsaturated polyester, epoxy resin and phenolic resin as matrix resin with glass fibre, be commonly called as glass fibre reinforced plastics) pipe mainly contains two kinds: a kind of is to be all inside and outside the shape of common circle; Another outer surface is plum blossom shape, and internal surface is the shape of common circle.
Its shortcoming is: if the first wall thickness attenuation: 2 ~ 4mm, cost of material reduces, its intensity also can and then reduce, and after 9 meters long pipes erect, can obviously feel under nature and rock.If more than wall thickness is thickeied 4mm, cost of material can significantly increase, and the price of product can be higher.The second outer surface plum blossom: more more than 8, the ditch of plum blossom is darker, and intensity can increase, but mould to add trade union more difficult, the cost of mould is just more expensive.
The length of glass fibre reinforced plastics pultrusion die of the prior art is the 900mm left and right, and the surface finishment of moulding and straightness accuracy are all very good, and taking wire cutting machine tool to process plum blossom shape is very difficult on the height of lathe.The ditch of plum tube is darker, and the back-off on mould is just larger, and processing is just more difficult, has limited the degree of depth of plum blossom pipe trench, thereby has limited the intensity of existing plum tube.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of plum tube, on the basis of existing pipe and plum tube, at the inwall of pipe, a plurality of arc convex is set, and consists of the stiffening rib of plum blossom-shaped; Outer wall at pipe arranges a plurality of arc grooves, consists of plum blossom-shaped.The raw material that this plum tube uses reduce, and product weight alleviates, and landed cost also can correspondingly reduce, and can be to the mass formation adverse effect of whole pipe.
The technological scheme that the utility model adopts is: a kind of plum tube, and the inwall of described plum tube is provided with a plurality of arc convex, and described arc convex consists of stiffening rib, and the outer wall of described plum tube is provided with a plurality of arc grooves.
Described a plurality of arc convex, arc groove are on the tube wall that circumference array evenly is positioned at plum tube, and arc convex is corresponding with the arc groove position.
Described arc convex, arc groove are respectively eight, and any two adjacent a pair of arc convex, the angles between arc groove are 45 °.
A kind of plum tube of the utility model, because the plum tube inwall arranges the stiffening rib that arc convex consists of, the intensity of plum tube is high, and the cost of material is low.Outer wall at pipe arranges a plurality of arc grooves, and the material of use can reduce, and product weight will alleviate, and landed cost also can reduce.Arc groove can increase the frictional force of contact surface, prevents from skidding.
Description of drawings
Fig. 1 is a kind of plum tube cross-sectional structure of the utility model schematic diagram.
Embodiment
A kind of plum tube, the inwall of described plum tube 1 are provided with a plurality of arc convex 2, and described arc convex 2 consists of stiffening rib, and the outer wall of described plum tube 1 is provided with a plurality of arc grooves 3.Described arc convex 2, arc groove 3 are respectively eight, consist of plum blossom-shaped.Be circumference array and evenly be positioned on plum tube 1 tube wall, arc convex 2 is corresponding with arc groove 3 positions.Any two adjacent a pair of arc convex 2, the angle α between arc groove 3 are 45 °.
As required, described arc convex 2, arc groove 3 can be designed as a plurality of, as: as described in arc convex 2, arc groove 3 be: 10,12,16 pairs.
With the also easily processing of plug on the supporting mould of the utility model plum tube, can take the processing of machining center and dividing head, the cost of mould also can correspondingly reduce.
