TH5972B - A machine for producing spiral pipes - Google Patents

Abstract

One of the methods used in the manufacture of helical pipes Method consists of Spraying of thermoplastic synthetic resin material in the melt state. in the form of a pipe to obtain the diameter and wall thickness of Tubular fuselage as specified and the winding of the ridged material in the condition molten which is hollow or solid in the sprayed part The end of the spray tube that revolves around the outside of the body that is discussed and Forged to be related to the speed of the spray to make the body shape. The pipes that are sprayed and molded form a composite that are hollow thread or solid thread A set of machines used in production pipe with a spiral ridge The machine consists of a rotatable fuselage arranged. Place it on the frame with the bearing around the outside of the source end. Spray, which provides a channel at the end of the tube, which has a hollow inside and outside. Formed together to spray thermoplastic synthetic resins. Go in a tubular form and a cylindrical swivel socket provides a channel. The end of the tube for spraying the ridge assembly with the hollow, cylindrical swivel socket, is positioned at the end of the The fuselage can be rotated around the outer surface of the fuselage shaped pipe that is sprayed forged mask. Suddenly after being sprayed by the crucible (extrusion die) is opposite the tube end of the socket.

Claims (3)

1. A ready-made machine for producing plastic pipes. With a curled ridge Is an outer spiral consisting of A flue socket formed from an inner tube-shaped assembly and an outer tube-shaped assembly forming a flow channel. The first pipe is formed during it for synthetic resin materials. Thermoplastic And a nozzle for spraying a nozzle for spraying One head for forming plastic pipes A pipe-shaped frame located around the outer pipe-shaped socket assembly. To form a shaped flow channel The second tube for thermoplastic synthetic resin material. While called Pipe-shaped frame and that is higher than the outer tube-shaped socket assembly It has a common axis called a channel. 1st pipe flow A rotatable body that is positioned around the aforementioned tubular frame. The bearing device is placed between the so-called rotatable body and the so-called tubular frame to allow the body to rotate. Can be rotated around the frame, and the pipe-shaped socket assembly connected to the rotating body as Said to spray thermoplastic synthetic resin material out of place. This is called the second pipe-shaped flow channel onto the outer surface of the pipe. Plastic that has been sprayed from the so-called Nozzle for spraying And causing the ridge to form a spiral up by the rotation of the body. Spin it 2. The machine completes claim No. 1 here, called That the part of the pipe socket consists of a channel at the end of the pipe that is shaped The body that forms a hollow ridge on the so-called The outside surface of Tee called plastic pipe. 3. The machine is completed in accordance with Claim No. 1 here called That the inner tube-shaped socket assembly of the so-called spout consists of a protrusion Which will extend out of the so-called The outer casing assembly here is called the spray nozzle and is called the pipe socket element. Will spray resin material Synthetic thermoplastic onto the outer surface of the plastic tube. Onto the outer surface of the plastic pipe as it passes over the section Protruding
