Description

Technical Field

[0001] The utility model relates to the technical field of plastic-aluminum steady-state pipe installation, in particular to a plastic-aluminum steady-state pipe rolling machine. Background Art

[0002] Random copolymer polypropylene (PPR) plastic-aluminum stable pipe has a five-layer structure, as shown in the figure below. Before the plastic-aluminum stable pipe is connected and installed with pipe fittings, the outer coating layer, outer rubber layer, aluminum layer and inner rubber layer of the composite pipe need to be rolled and cut to meet certain outer diameter requirements before hot-melt socket connection with pipe fittings of the same specifications can be performed.

[0003] Chinese patent "A tool for electric rolling of aluminum strips at the ends of aluminum-plastic composite pipes" (ZL201822150188.4) discloses a rolling tool for aluminum-plastic composite pipes, which has the above two disadvantages: 1. There is no mechanism for clamping the aluminum-plastic composite pipe, resulting in the need for people to hold the aluminum-plastic composite pipe and insert it into the working circular hole of the tool for rolling when rolling the aluminum-plastic composite pipe, which is manpower-consuming; 2. When rolling the rolling tool, it is necessary to hold an electric drill and press the two cutter heads against the end face of the aluminum-plastic composite pipe to be rolled at the same time, which is not only manpower-consuming and labor-intensive, but also difficult to control the degree of rolling, which is likely to result in unqualified rolling and require secondary rolling, and the rolling efficiency is low.
