Embodiment Construction

[0049] The tapered milling cutter of the present invention changes the two faces of the milling cutter into two inner and outer faces with an included angle of 45 degrees on the basis of the flat milling cutter. The bearing is fixed, and the power of the motor is used to drive the gear to rotate the milling cutter to fix the two joints of the pipe or pipe fittings on the same axis, and cut out a female and a male socket with equal angles (Figure 1).

[0050] Among them, the conical milling cutter can be designed as an independent part, which can be manually picked up and placed in the frame for fixing pipes or pipe fittings. The advantage is that it is easy to carry in the field and saves costs. The disadvantage is that the operation is greatly affected by human beings.

[0051] In the specific implementation, it can be designed as a frame-connected body, which is convenient to operate and reduces labor intensity. It can realize automatic operation when equipped with a lifting ...

Abstract

The invention discloses a device and a method for sweating soldering plastic thin-walled tube cone mouth. It is characterized in that the device comprises a cone mouth milling cutter and a cone mouth heating plate, wherein the cone mouth milling cutter is provided with an inner conical cutter edge face and an outer conical cutter edge face forming an included angle of 30-60 degrees, and the cone mouth heating plate is provided with an inner heating face and an outer heating face forming an included angle of 30-60 degrees and both matched with the cone mouth milling cutter. The cone mouth fusion butting process can increase butting area of the thin-walled tube, improve fusion butting strength, realize large-scale application of the plastic thin-walled tube via popularization, correct butting face offset phenomenon caused by out-of-roundness of the plastic tube, and reduce quality accident caused by asymmetry of butting port.

Description

technical field [0001] The invention relates to the field of plastic pipes, in particular to a tapered hot-melt welding device and a hot-melt welding method for plastic thin-walled pipes. Background technique [0002] With the popularization of PE plastic pipelines, the connection process problems caused by the inherent characteristics of PE plastic pipes and metal pipes are becoming more and more prominent, especially with the further improvement of the performance of plastic raw materials and the improvement of compressive strength, the pipe wall can be made This contradiction becomes more pronounced when the thickness is thinner. [0003] From grade 63 of PE plastic raw material in the 1960s to grade 80 in the 1990s, the pipe wall used in the production and use is SDR11 (ratio of outer diameter to wall thickness). Since the current PE plastic raw material has been upgraded to grade 100, the wall thickness of the pipe can be To achieve SDR17 (the ratio of outer diameter t...
