Abstract
A forming module for a double-wall corrugated pipeline comprises a module body with a semicircular cylinder inner wall, wherein a plurality of semicircular convex ribbed bars and grooves are arranged on the inner wall of the module body and are adjacently arranged at intervals; and module closing line semi-slots along surfaces of the convex ribbed bars and the grooves are respectively and axially formed in an upper edge and a lower edge on the inner wall of the module body. At least one axial groove along the surfaces of the convex ribbed bars and the grooves is axially formed in the inner wall of the module body. The semicircular die closing line semi-slots are respectively formed in the edges of two end surfaces on the inner wall of the module body. A semicircular radial groove is formed in the surface of each wave crest section of the inner wall of the module body. The forming module disclosed by the invention is reasonable in design and simple in structure and is obtained by improving a traditional forming module. The manufactured double-wall corrugated pipeline is greatly enhanced in ring stiffness and fully meets high demand of special projects on ring stiffness of a plastic corrugated pipeline.
Description
Technical field
The present invention relates to a kind of mould for process pipeline, relate in particular to a kind of double-wall corrugated pipeline forming module.
Background technology
At present, the general some groups of moulds of coaxial setting that adopt of plastic double-wall corrugated pipeline are pressed to outer wall, every group of mould includes two semicylindrical forming modules, wherein each forming module inwall is equipped with the semicircular fin bar in some roads and groove, adjacent and the interval of fin bar and groove arranges, the fin bar is used for the trough of corrugating outer wall, and groove is used for the crest of corrugating outer wall.
Plastic double-wall corrugated pipeline is made of level and smooth circle tube inner wall and the outer wall of bellows-shaped (ripple outer wall), is bonded as one by high temperature extrusion between the trough section of outer wall and the inwall.When ring stiffness is had relatively high expectations in special engineering, the plastic double-wall corrugated pipeline of this structure will be crushed, because the crest section is hollow structure, the position of easy the flattening deformation just axial module closed line place between crest section top, two relative modules and the radial dies closed line place between the two adjacent groups mould, this just can't engineering demands.
Summary of the invention
The present invention provides a kind of double-wall corrugated pipeline forming module that strengthens the plastic double-wall corrugated pipeline ring stiffness in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of double-wall corrugated pipeline forming module, comprise the module body with semicircular cylinder inwall, the module body inwall is provided with the semicircular fin bar in some roads and groove, adjacent and the interval of fin bar and groove arranges, and described module body inwall top edge and lower limb all are axially arranged with module closed line half groove along fin bar and groove surfaces.
Described module body inwall is axially arranged with at least one axial groove along fin bar and groove surfaces.
Described module closed line half groove is continuous structure or the intermittent configuration that is made of at least two joints.
Described axial groove is continuous structure or the intermittent configuration that is made of at least two joints.
Described module body inwall both ends of the surface edge is equipped with semicircular mould closed line half groove.
Each crest section surface of described module body inwall is equipped with together semicircular radial slot.
Described mould closed line half groove is continuous structure or the intermittent configuration that is made of at least two joints.
Described radial slot is continuous structure or the intermittent configuration that is made of at least two joints.
Adopt technique scheme, have following beneficial effect:
1, at module body inwall top edge and lower limb module closed line half groove along fin bar and groove surfaces is set axially all, form the closed wire casing of complete module after two module body combinations, when the corrugating outer wall, can increase the ripple outer wall at the thickness at module closed line place like this, namely strengthen the intensity at this place.
2, the module body inwall is axially arranged with at least one axial groove along fin bar and groove surfaces, can increase like this ripple outer wall surface integral body thickness in the axial direction when the corrugating outer wall, namely strengthens the intensity of ripple outer wall.
When 3, two groups of mould shafts are to connection, the mould closed line place of annular is weakness, module body inwall both ends of the surface edge all arranges semicircular mould closed line half groove, just form a closed wire casing of complete mould at two groups of die assemblies at one like this, when the corrugating outer wall, can increase the ripple outer wall at the thickness at mould closed line place like this, namely strengthen the intensity at this place.
4, each crest section surface of module body inwall is equipped with together semicircular radial slot, can increase like this thickness of crest section surface integral body on Zhou Jing when the corrugating outer wall, namely strengthens the intensity of crest section.
5, according to the different requirements of special engineering to the plastic double-wall corrugated pipeline ring stiffness, the intermittent configuration that per pass module closed line half groove, axial groove, mould closed line half groove and radial slot are set to continuous structure or are made of at least two joints like this can economical with materials and reduction cost.
The present invention is reasonable in design, simple in structure, improves getting final product on the basis of existing forming module, and the ring stiffness of the double-wall corrugated pipeline that produces strengthens greatly, fully satisfies special engineering to the demanding demand of plastic corrugated pipe road ring stiffness.
