In the proposal, the pipe is composed of the inner layer and the outer layer which are interconnected via the ribs to form a pipe, in particularly, the inner wall of the inner layer of the pipe is provided with helical ribs which are evenly distributed in an oblique-straight way, and under the guide of the helical ribs, water streams flow downwards along the inner wall of the inner layer of the pipe according to the oblique-straight trend of the helical ribs during drainage in order to avoid the water streams causing strong impact to the inner wall of the inner layer of the pipe, thereby achieving the purpose of lowering noise.
Description
Technical field
The present invention relates to a kind of oblique-straight helical water guide rib tubing, and the processing method of oblique-straight helical water guide rib tubing, building material field belonged to.
Background technique
The drainage pipe of installing in the existing house mostly is mono-layer tube or composite pipe greatly, when water in process of flowing down, current can impact the bigger noise of tube wall generation, and noise almost to the sky transmitted out entirely, cause the noise pollution of surrounding environment.Though existing composite pipe can intercept the part noise, but because the inwall of pipe is smooth inwall, current can not paste tube wall and flow, pipe itself can not reach the effect of noise reduction, just rely on the tube wall of hollow to absorb the noise that the inwall current produce, can only play the obstruct function of noise, and such composite pipe exists consume material many, the cost height, problem such as price is expensive.
Summary of the invention
The objective of the invention is provides a kind of tube wall to have sound insulation and noise reduction in order to overcome the shortcoming of prior art, and it is mobile to make current paste tube wall simultaneously again, thereby reaches the oblique-straight helical water guide rib tubing of noise reduction purpose.
Another object of the present invention provides a kind of processing method of producing oblique-straight helical water guide rib tubing.
The technological scheme of oblique-straight helical water guide rib tubing of the present invention is: tubing is made of internal layer and outer institute, connect by rib between described internal layer and the skin, it is characterized in that being shaped on spiral bar on the inwall of tubing internal layer, described spiral bar is linearly oblique uniform, and the angle β of spiral bar center line B and tubing center line A is 12 °-20 °.
The present invention relates to a kind of oblique-straight helical water guide rib tubing, tubing is made of internal layer and outer institute, and connect into a pipe by rib between internal layer and the skin, particularly on the inwall of tubing internal layer, be shaped on linearly oblique uniform spiral bar, during draining, current are under the water conservancy diversion of spiral bar, and the oblique straight line of pressing spiral bar is past dirty along the inwall of tubing internal layer, avoid current that its inwall is produced stronger impact, therefore reach the purpose that reduces noise; The inside and outside connection by rib between two-layer of described tubing forms the sound insulation hole, and the less noise that water produces the tube wall internal layer is again by the weakening effect in sound insulation hole, and the draining sound that passes to the external world is littler, can not disturb the people normally to have a rest basically; Especially the angle β of spiral bar center line B and tubing center line A is 12 °-20 °, can reach the effect of noise reduction, helps draining again.Because angle β is too small, a little less than the diversion guide functions, erasure effect is poor, does not reach desirable purpose.Overcome prior art simultaneously because of spiral angle too big (curved shape), and made the current undulate break through spiral bar, " fly stream and jump the dam " phenomenon occurred, caused and repeatedly impact tube wall, caused the defective of erasure effect difference equally.Angle β is 12 °-20 °, and the diversion guide functions is the most desirable, and erasure effect is very remarkable.
The processing method of oblique-straight helical water guide rib tubing of the present invention, the extrusion die that comprises tubing, its described extrusion die comprises the connecting base that is installed on the cross-head, connecting base connects handpiece body, handpiece body outer wall mount inlet mould, mandrel and the hollow bar of loosing core is installed in mouthful mould, be provided with the shunting vertebra in described connecting base and the handpiece body, the shunting vertebra connects the afflux vertebra through flow distribution plate, form the shunting chamber between shunting vertebra and the connecting base, form manifold between afflux vertebra and the handpiece body, it is characterized in that in the described afflux vertebra rotatingshaft being installed, rotatingshaft is driven by power, rotatingshaft connects mandrel, at the mandrel outer wall helix core rod is installed, is shaped on the spiral bar groove on the helix core rod, the folder degree α of described spiral bar groove center line and helix core rod center line is 15 °.
The processing method of oblique-straight helical water guide rib tubing of the present invention has been installed the hollow bar of loosing core in the mouth mould, the material of inflow entrance mould forms axial hole through the hollow bar of loosing core, make the tube wall of tubing form hollow, reach the purpose that intercepts noise, and the hollow tube wall can save material again, cost is low; Particularly helix core rod is installed at the mandrel outer wall, be shaped on the spiral bar groove on the helix core rod, the folder degree α of described spiral bar groove center line and helix core rod center line is 15 °, when extruding, drives the rotatingshaft rotation by power, rotatingshaft drives mandrel, mandrel drives the helix core rod rotation, just because of the helix core rod of rotation has been arranged outside mandrel, is shaped on the spiral bar groove on the helix core rod, just reach the tubing of producing the spiral bar inwall, obtain satisfied effect.But in actual production, relevant with the rotating speed of helix core rod because of the spiral bar gradient that the spiral bar groove is produced, the rotating speed of helix core rod is fast, and gradient is just big, but can not surpass 20 °, and the rotating speed of helix core rod is slow, and gradient is just little, and general minimal slope is 12 °.The tubing internal layer inwall that this programme is extruded forms spiral bar, and current reduce the bump of current to tube wall along spiral helicine rib toward current downflow, reduces the noise that sends because of current bump tube wall, reaches the purpose of noise reduction, has very outstanding advantage.Therefore, this processing method adopts helix core rod and be shaped on the spiral bar groove on helix core rod, is skillfully constructed, and is rational in infrastructure, extrudes desirable tubing under the drive of power.
The processing method of oblique-straight helical water guide rib tubing of the present invention, the depth H of described spiral bar groove are 1.5-2.7mm, and for meeting the related standards of country, the spiral bar height that the spiral bar groove is produced is generally greater than described tubing internal layer wall thickness 0.5mm.Described handpiece body outer wall installs and fixes connecting plate, the mouth mould is installed on the fixed connecting plate, be shaped on bayonet socket at mouth mould inwall with the fixed connecting plate joint, described hollow is loosed core and is shaped on fixture block on the bar, fixture block matches with bayonet socket, the loose core fixture block of bar of hollow is crushed between mouthful mould and the fixed connecting plate, and is easy for installation reliable again.Described fixedly connected and a mouthful mould are equipped with a mouthful molded sheets outward, and mouthful molded sheets is through coupling screwing machine head body, and it is firm to install.Be shaped on the chain cylindrical void in the described flow distribution plate, rotatingshaft connects motor through chain, drives rotatingshaft by motor through chain and rotates reliable.Described rotatingshaft and mandrel are made one, need not connect, and be easy for installation, be made into integration not fragile, long service life.
