Embodiment Construction

[0012] The present invention is a hanger PE pipe cladding process, the specific steps are as follows:

[0013] a. The steel strip is released from the uncoiler 1, and the steel strip is straightened by the steel strip straightener 2, and the speed of the steel strip is set at 3.5m / min.

[0014] b. Pre-heat the corrected steel strip with a high-frequency heating machine. The frequency of the high-frequency heating machine is set to 700Hz, and the temperature is 100°C. Then it passes through the extrusion die 3. Extruder 4 simultaneously extrudes resin and wraps it around the steel strip to form a strip, and at the same time, extrusion die 3 performs initial shaping of the strip. The speed of extruder 4 is set at 38.8 rpm, and the outlet temperature is 200°C.

[0015] c. After the strip is initially shaped, the ribs of the strip are shaped again through the shaping die 5, and at the same time, the shaping table 6 is cooled by cooling water. The re-setting is a total of 4 times ...

Abstract

The invention relates to a clothes hanger PE pipe compositing process. The clothes hanger PE pipe compositing process comprises the steps that 1, a steel belt is discharged out of an unreeling machine and corrected through a steel belt correcting device; 2, the corrected steel belt passes through an extrusion die, at the moment, resin is extruded through an extruder located at the same side as the extrusion die at the same time, and the resin is arranged outside the steel belt in a wrapping manner, so that belt materials are formed; 3, reinforcing ribs of the belt materials obtained after preliminary shaping are subjected to secondary shaping through a shaping die, and meanwhile, cooling is conducted through cooling water of a shaping table; 4, the cooled belt materials are blown to be dry through blowers, and then the belt materials are pulled to a winding machine through a traction machine; 5, a sizing material is extruded through an extruder located at the upper end of the winding machine and bonded to one side of each belt material output through the winding machine, and then a clothes hanger PE pipe is formed through a formation cage; and 6, the formed clothes hanger PE pipe output through the formation cage is cut through a cutting machine. The clothes hanger PE pipe compositing process has the beneficial effects that bonding strength among the belt materials in the clothes hanger PE pipe is high; and the steel material and the resin are composited well.

Description

technical field [0001] The invention relates to a composite process of PE pipes for clothes hangers. Background technique [0002] Hanger PE pipe has the advantages of corrosion resistance, light weight, easy installation, large flow rate, long life (50 years), etc. It can replace pipes made of high energy consumption materials (cement, cast iron, ceramics, etc.), and is an environmentally friendly green product. [0003] At present, there are still various problems in the PE pipes for clothes hangers produced by the existing process of producing PE pipes for clothes hangers, such as insufficient bonding strength between strips and insufficient lamination between steel strips and resins. OK wait. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a cladding process for hanger PE pipes with good bonding strength between strips and good lamination between steel strips and resin. [0005] In order to solve the above-...
