Problems solved by technology

[0012] First, the socket and socket are directly processed by winding, which cannot ensure accuracy and is prone to leakage;
[0013] The second is that the cutting of the socket fit and flash at both ends requires manual cutting, the labor intensity of the workers is high, and the noise generated by cutting is large;
[0014] The third is that the production efficiency is low, and it is not the final product after demoulding, and heating resistance wires and cutting are required, which results in high labor costs;
[0015] Fourth, in addition to dispatching additional professional and technical personnel for on-site construction, conditions such as sunny weather, no water, and power supply are also required.

Embodiment Construction

[0039] The present invention will be further described below with specific embodiment:

[0040] A production process for pipes, comprising the steps of:

[0041] (1) Making a joint with a socket and a joint with a socket: making a joint with a socket and a joint with a socket by plasticizing and forming;

[0042] (2) Set the joint with the socket and the joint with the socket on the mold;

[0043] (3) The mold rotates along its axis, and the joints with sockets and sockets are heated to 120°C-150°C by a physical heating device; the heating temperature can be arbitrarily selected within the above range, and generally controlled at 135°C± 5°C. The rotation of the mold is driven by the rotating device. The structure of the rotating device is as follows: the two ends of the mold are respectively arranged between two rollers, and the two rollers are respectively driven by motors to rotate, and then drive the mold located on them to rotate around the axis.

Abstract

The invention belongs to the technical field of pipes, and particularly relates to a production technology of pipes. The production technology of the pipes comprises the following steps: (1) manufacturing a joint in a plastification forming manner; (2) sleeving a mold by using the joint; (3) rotating the mold along the axis thereof, heating the joint to the temperature of 120-150 DEG C by a physical heating device, and meanwhile moving a mold heating device in the axial direction of the mold to heat the mold to the temperature of 120-150 DEG C; (4) heating raw materials in extrusion equipment to the temperature of 180-190 DEG C; (5) extruding the molten raw materials by the extrusion equipment, moving the extrusion equipment in the axial direction of the mold, winding the raw materials on the surface of the mold to form a pipe body, and directly fusing two ends of the pipe body to the joint at high temperature; (6) cooling and demolding. The joint is subjected to precision injection molding by a material which is the same as the material of the pipes, the precision is high, interchangeability is good, and troubles of matching and correcting in a construction site are avoided.

Description

Technical field: [0001] The invention belongs to the technical field of pipes, in particular to a production process of pipes. Background technique: [0002] The existing processing methods of PE and PP pipes are directly extruded on the mold or extruded and wound, and wound at both ends to form a socket and a socket, and finally fixed on the inner wall of the socket for two adjacent sections The heating resistance wire or rubber ring that is melted and connected between the socket and the socket of the water supply and drainage pipe. [0003] For example, the invention patent with the authorized announcement number CN 103264508B discloses a large-caliber glass fiber reinforced water supply pipe winding production process, including the following steps: [0004] 1) making a winding mold, and the outer diameter of the winding mold is equal to the inner diameter of the water supply pipe; [0005] 2) Use the axis of the winding mold as the rotating shaft to drive the winding ...
