Automatic tee shaping equipment and shaping method thereof

Abstract

The invention discloses automatic tee shaping equipment and a shaping method thereof. The equipment comprises a tee, a bottom plate, and a branch pipe machining die, a tee clamping cavity and a flaring cavity which are coaxially arranged, wherein the tee clamping cavity is formed on an end part of a retainer plate; a branch pipe side of the tee clamping cavity is next to the branch pipe machiningdie; a core rod is arranged in the flaring cavity; one end of the core rod is fixed on a core rod plate and the other end of the core rod is inserted into the flaring cavity; the core rod plate is connected with a piston rod of a hydraulic cylinder; a needle rod capable of reciprocating is arranged in a die cavity of the branch pipe machining die; the needle rod is driven by a secondary shaping part; the branch pipe machining die is fixed above the bottom plate; the retainer plate can reciprocate along the bottom plate; a main spring is arranged between the retainer plate and the core rod plate; and the branch pipe machining die is a necking die or a flaring die or a shaping die for correcting a center distance between two branch pipes of the tee. By the invention, the tee can be subjected to flaring, necking, shaping and other machining processes simultaneously in the same equipment, the degree of automation is high, the conventional machining process is greatly simplified, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mold processing, and more specifically relates to an automatic three-way shaping device and a shaping method thereof. Background technique [0002] Tee is a widely used pipe connector, mainly used in pipe branches, with a wide range of applications. There are many ways to form the tee, including die drawing method and hydraulic bulging method. The die drawing method is to open a hole at the part of the stretched branch pipe, put the tube blank into the forming die after heating, and put the drawing tube into the tube blank The punching die of the extension pipe applies pressure to the tube blank, the tube blank is radially compressed and the metal flows in the direction of the branch pipe and forms the branch pipe under the stretching of the die. The hydraulic bulging method injects liquid into the pipe fitting, and the hydraulic cylinder increases the pressure of the liquid in the pipe fitting, and the ...

Problems solved by technology

[0003] Most of the existing three-way pipe expansion (or pipe shrinkage) processes rely on semi-automatic or even manual methods to go through multiple steps of processing procedures. Workers need to use various tools many times, which is inefficient, time-consuming, and the yield rate is unstable.

At the same time, since the shaping of the main pipe port and the branch pipe port of the tee is performed separately, the verticality and concentricity of the main pipe port and the branch pipe port cannot be guaranteed after shaping, thereby reducing the yield
