The invention discloses a process and equipment for biaxial orientation processing of a plastic pipe through an elastic cloth bag method. The process comprises the following steps that s1, a pipe blank workpiece is coaxially placed in a sizing cylinder; s2, an elastic cloth bag is coaxially arranged in the pipe blank workpiece; s3, the interior of the sizing cylinder is heated, the elastic cloth bag is blown, and the elastic cloth bag is inflated and expanded to enable the pipe blank workpiece to be expanded and attached to the inner wall of the sizing cylinder; and s4, the interior of the sizing cylinder is cooled, and the pipe blank workpiece is taken out. According to the production method, the hot pipe blank workpiece is evenly expanded to the inner wall of the sizing cylinder throughforce generated through the expansion of the elastic cloth bag and then taken out after being cooled, the efficiency is high, potential safety hazards are low, the expanded pipe blank is accurate in size, the orientation degree is artificially designed, the quality is controllable, and the product performance is stable.
Description
technical field [0001] The application relates to the field of pipe fittings, in particular to a production method for expanded pipe blanks. Background technique [0002] At present, in the production of expanded tube blanks, a punch is pressed into the blank to expand the end of the blank to mechanically form the metal tube blank, but the efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a production method for expanded tube blank, so as to overcome the deficiencies in the prior art. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] The embodiment of the present application discloses a process and equipment for biaxially oriented processing of plastic pipes by elastic cloth bag method, which is characterized in that it includes the following steps: s1: placing the tube blank workpiece coaxially in the sizing cylinder; s2: placing the tube blank workpiece i...
