Description
Technical Field
The utility model relates to a double-walled bellows extrusion tooling especially relates to a double-walled bellows extrusion tooling suitable for high-speed production line.
Background
Double-walled corrugated pipe is a new type of pipe with an outer wall of annular structure and a smooth inner wall. It has been widely used as a buried drain pipe, an underground cable pipe, etc. in a considerable range to replace conventional cast iron pipes, cement pipes, general plastic pipes, and wound corrugated pipes. At present, the main varieties of the double-wall corrugated pipe are polyvinyl chloride (PVC), high-density polyethylene (HDPE) and polypropylene (PP).
The double-wall corrugated pipe production process is characterized in that materials are extruded to an extrusion die from an extruder in a molten state, the extrusion die changes the rod-shaped materials into circular rings and extrudes the circular rings to a forming module, the materials are formed under the constraints of the forming module (the outer wall is tightly attached to the outer wall of the forming module for forming through vacuumizing) and a water jacket (the inner wall of a cooling tank for forming), the formed double-wall corrugated pipe is continuously conveyed forwards, the corrugated pipe passes through the cooling water tank and is conveyed to a cutting machine, and the cutting machine cuts out the corrugated pipe meeting the technical requirements according to.
The existing extrusion die is complex in structure, the extrusion speed is not suitable for a high-speed production line, and a double-wall corrugated pipe extrusion die suitable for the high-speed production line is urgently needed.
Disclosure of Invention
The utility model provides a to prior art not enough, the utility model provides a simple structure is applicable to the double-walled bellows extrusion tooling of high-speed production line.
The double-wall corrugated pipe extrusion die suitable for high-speed production comprises an inner spiral body, an outer spiral body and a flow channel barrel, wherein the outer spiral body and the flow channel barrel are connected with a material distribution disc connected with an extruder, two feed inlets are arranged on the material distribution disc, an outer sleeve and the outer spiral body form an outer wall flow channel, the outer spiral body and the inner spiral body form an inner wall flow channel, the inner spiral body is fixed with a central shaft, each feed inlet is respectively connected with the inner wall flow channel and the outer wall flow channel, an outer wall inner die lip and an outer wall outer die lip are arranged at an outlet of the outer wall flow channel, and an inner wall inner.
The outer sleeve is provided with an outer wall gap adjusting device, the outer wall outer mold lip is provided with an outer wall mouth mold inclined wall adjusting device, and the joint of the inner spiral body and the central shaft is provided with an inner wall mouth mold inclined wall adjusting device.
The utility model has the advantages that: the parts are few, and the installation is convenient; feeding is carried out on two sides, so that the resistance is small and the feeding is uniform; the clearance of each runner is adjustable, can form the bellows of different wall thicknesses, and application scope is wider.
