A processing method for welding a plastic pipe body with holes and a device for realizing the same

Abstract

The invention discloses a processing method for welding a plastic part with a hole in a plastic pipe body, which comprises the following steps: S1, fixing the plastic part and the pipe body in an upper die and a lower die respectively; The body is relatively arranged, and the extruded part moves down to extrude the end of the pipe body to form a flanging; a device for welding plastic parts with holes in a plastic pipe body, including a pipe body, a plastic part and a base, and the upper side wall at one end of the base is fixed There is a telescopic rod 1, the driving end of the telescopic rod 1 is fixed vertically upward with a connecting plate, the end of the connecting plate far away from the telescopic rod 1 is fixed with a motor 1, and the driving end of the motor 1 is vertically fixed downward with a turntable , the turntable is provided with an opening, and the expansion rod 2 is fixed in the opening. The invention uses ultrasonic energy to generate high-temperature heat energy at the connection between the plastic part and the pipe body, and quickly connects the contact surface through extrusion without melting and collapse, and strengthens the strength of the weld through the inward folding connection of the flanging to ensure the welded joint. Stablize.

Description

technical field [0001] The invention relates to the technical field of plastic pipe body processing, in particular to a processing method for welding a plastic pipe body with holes and a device for realizing the same. Background technique [0002] The plastic pipe body is generally made of synthetic resin, that is, polyester, with the addition of stabilizers, lubricants, plasticizers, etc., and is extruded in a pipe-making machine by a "plastic" method. 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] Traditionally, thermal welding is used to directly connect the plastic pipe body and the plastic parts, and the thermal welding generally adopts the method of thermally melting the joint between the pipe body and the plastic part with a thermal welding pliers, and the molten plastic is squeezed and flows to the ou...

AI Technical Summary

Problems solved by technology

Infrared heating is used for the plastic parts with holes, and the plastic pipe body is welded and connected by hot plate heating. However, during the welding process, there is still the problem of plastic melting and collapsing to the outside, which leads to poor welding sealing.
