Embodiment
Embodiment one, as shown in Figures 1 to 5, a kind of enhancement mode plastic-steel-wound tubing, comprise the spiral helicine tubing body through being wound by band, and use melt viscosity to connect in succession at faying surface place, the tubing forming should be continuous, has and axially bears preferably intensity and good hoop rigidity.
The needed band 1 of paper wrapped tube, as shown in Figure 3, the moulding of this band needs three key elements, and first will have steel band 2, and steel band forms a kind of stand-by steel band after uncoiling, flattening, oil removing, derusting process.
Reinforced layer 3, this reinforced layer 3 can be such as steel plate, galvanized sheet, aluminium strip or other sheet alloy, and on sheet metal, can punch to save material or with steel wire or iron net etc., also claim wire netting, the relatively good understanding of sheet metal is exactly a thin sheet metal.Wire netting, mesh can be rhombus.But as sheet metal or the wire netting of reinforced layer 3, need to roll, smooth sheet metal or wire netting are rolled into the effect with a Z-shaped flanging 31, thisly can easily realize by Rolling roller mould, the Z-shaped flanging 31 of this rolling can improve the intensity of lap-joint.In fact, in the process of traditional wrapped tube moulding, in lap-joint owing to there being flex point, here be the disconnected pipe of favorite, secondly sometimes also can break at non-overlapping place, or break in the place of stud (steel band), because steel band can not just in time be wrapped in plastics middle while production, the plastics that is to say steel band left and right are normally asymmetric, if left side or right side are excessively thin, and can be from the disconnected pipe of steel band and plastics point of intersection.Sheet metal or wire netting in this band, are added, sheet metal own or wire netting folding can not break for one time twice, this novel tube be the pipe that can not break, and in the band of lap-joint, be also provided with sheet metal or wire netting is strengthened, disconnected pipe is become impossible.Due to the existence of reinforced layer, extraneous sharp objects also can not punctured tubing, tensile strength strengthens greatly simultaneously simultaneously.
Steel band and reinforced layer have two kinds of position relationships, and one is that steel band 2 does not contact with reinforced layer 3 or has part contact, in compound by mould, is wrapped by band of formation simultaneously, as shown in Figure 3.The second is that stud is vertically welded on reinforced layer by spot welding, this,, carrying out before compound needing to increase a spot welding or laser welding equipment, connects both, is then being combined into band, because stud and reinforced layer are in inner shape all-in-one-piece structure, so this intensity is higher.
In composite dies 4, molten plastic is from the feed simultaneously of two imports up and down of mould, the plastics that sheet metal or wire netting are melted complete coated, and the width of sheet metal or wire netting is slightly less than the width of base plate plastics, and and stiffening rib steel band used orthogonal.So both utilized the high ring rigidity of plastic-steel spirally-wound pipe, improve again the intensity of body portion by increasing sheet metal or wire netting, and owing to being first to form band, again by being wound tubing, so, ensured the ring stiffness of tubing, strengthen again the tensile strength of tubing and the ability of resistance to external environment, increased substantially the cost performance of tubing.
The junction, side of described band body adopts the alternating expression bridging arrangement of Z-shaped flanging 31, greatly increase area of contact when two sides are bonding, more firm while making tubing bonding, greatly improve the joint strength of tubing, ensured that higher stretching is strong, tensile strength is original more than 3 times.
Embodiment two, as shown in Figures 6 to 9,
Band difference, first, the sheet metal or the wire netting that use as reinforced layer do not need rolling directly to use, secondly, with the mould difference of material forming, the both sides of the described band of the band after moulding in faying surface are respectively the first faying surface 61 caving in from inside to outside and the second faying surface 62 certainly caving in outside to inside, because reinforced layer is placed in the middle, so be very thin one deck at the sheet metal at two faying surface places or the polyethylene cover at wire netting place, and the lap length of two faying surfaces is across a stud, form an external reinforcing spiral in lap-joint like this, eliminate the thin link of weld, the hoop intensity of weld is significantly improved, the load performance of tubing is multiplied.
In the process of actual band compound molding, plastics are all the heated fluids having melted, certainly to each local the flowing in mould, so certainly have some plastics at the first faying surface and the second faying surface place.In the time making, the sheet metal of both sides or wire netting, can carry out bending slightly, forms stack, to strengthen the intensity of lap-joint in the process of overlap joint.
In actual production, single strips is generally designed to 3 to 4 studs, and the lap-joint of this tubing is across a stud, and the faying surface of lap-joint is longer, and has individual stud on faying surface, can bear so larger interior pressure at faying surface place.And original traditional entwining tube is opened by Nei Yashicong lap-joint easily by drum in lap-joint, this just there will not be, because lap-joint has a circle steel band protecting outside, prevents that it is swollen outward, and faying surface is longer.
The external ring stiffness that ensures tubing has requirement to the height of steel band here, comprise the material of steel band, be exactly the width of steel band in addition, and length is irrelevant, another is exactly that the centre distance of two studs is relevant, be exactly that stud is more intensive, ring stiffness is higher, and the centre distance of stud is less certainly, also can play certain promoting effect to the anti-interior pressure energy power of tubing, just as steel wire, the closeer anti-pressure ability of net is also larger.If steel plate anti-pressure ability is just larger, if do draining, net is just enough in fact, if do more high pressure feedwater, or with sheet metal, certain, sheet metal can carry out pierced process processing.
Outside technical characteristics described in specification, be the known technology of those skilled in the art.
