However, since the mold can only heat the inner wall of the plastic pipe, for some plastic pipes with thicker pipe walls, the inner and outer walls of the plastic pipe are heated unevenly when the mold is flanging, resulting in the outer wall not softening when flanging. Giving molds may easily lead to nozzle breakage, flanging failure and even plastic pipe scrapping

Embodiment Construction
[0019] The present invention will be described in further detail below by means of specific embodiments:
[0020] The reference signs in the drawings of the specification include: mounting seat 1, axial slideway 11, radial slideway 12, stopper 2, clamping hoop 21, heating slide 3, heating probe 31, flanging slide 4 , mold 41, rotating shaft 5, turntable 51, handle 52, gear 53, plastic tube 6.
[0021] The concrete technological process of the present embodiment is:
[0022] 1. Clamp the plastic pipe: Take two arc-shaped clamping hoops and hinge relative to each other, form a round through hole between the clamping hoops, and use screws to connect the two clamping hoops; loosen the screws, and put The plastic tube is placed between the two clamping hoops, and the two clamping hoops are fastened and fixed and locked with screws. Both ends of the plastic tube are locked by clamping hoops; a slidable The stopper is fixed with locking screws to limit the axial displacement of the...

Abstract
The invention relates to the technical field of pipe machining, and discloses a plastic pipe port flanging process. The plastic pipe port flanging process comprises the technological flows of: (S1) clamping of a plastic pipe; (S2) arrangement of the heating device; (S3) arrangement of the flanging device; (S4) heating of a pipe port; (S5) flanging molding; and (S6) cooling and surface treatment. Compared with the prior art, the plastic pipe port flanging process changes a heating mode to heating from internal of plastic, so that the heating becomes more uniform, the uniform heating of the inner wall and the outer wall of the pipe port is realized, the softening effect is better, and the breakage of the pipe port in reflanging is prevented.
Description
technical field [0001] The invention relates to the technical field of pipeline processing. Background technique [0002] The pipe is the main component of the pipeline. According to the material, there are several types of pipes, such as steel pipes, cast iron pipes, reinforced concrete pipes, and non-metallic pipes. Plastic pipes are generally made of synthetic resin, that is, polyester, added with stabilizers, lubricants, plasticizers, etc., and extruded in a pipe making machine by a "plastic" method. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing and convenient construction, it has been widely used in many fields. It is mainly used for water supply system piping, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation in housing construction. [0003] In order to adapt to the use in different work fields, plastic pipes are often cut...
