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

Example Embodiment

[0030] Example one

[0031] An automatic tee shaping device of the present invention is used for tee 21, which is used to shrink the diameter of the branch pipe end of tee 21 to x while expanding the diameter of its main pipe port to y.

[0032] Such as Figure 1-4 Shown. The automatic three-way shaping equipment includes a secondary shaping part fixing plate 1 coaxially arranged on the bottom plate 13, a secondary shaping part, a main shaping part and a hydraulic cylinder 12, wherein the main shaping part is arranged between the auxiliary shaping part and the hydraulic cylinder 12. The bottom plate is provided with a flat slide rail 14 on which the movable part of the main shaping part slides back and forth.

[0033] The necking die fixing plate 3 of the secondary shaping part is fixed on the bottom plate 13 and the necking die 8 is provided. There are two through holes of the ejector pin for the ejector pin 4 to slide back and forth in the fixed plate 3 of the shrinking die, and...

Example Embodiment

[0040] Example two

[0041] On the basis of the first embodiment, the movement structure of the withdrawal needle in the secondary shaping part is changed. The auxiliary shaping part is composed of the mandrel fixing plate and its driving cylinder, instead of the fixing plate 1, the auxiliary spring, and the mandrel in the first embodiment. The driving cylinder is arranged on one side of the shrinking die, and the end surface of the fixed plate is fixed with a withdrawal needle. The process and return of the withdrawal needle are controlled by the driving cylinder, which is a hydraulic cylinder or an air cylinder. The rest of the structure is the same as the first embodiment, and the description is not repeated here.

Example Embodiment

[0042] Example three

[0043] See Figure 5 , On the basis of the first embodiment, the movement structure of the withdrawal needle in the secondary shaping part is changed. The auxiliary shaping part includes a top rod fixing plate 5, a push plate 18, and a cross rod 19, instead of the fixing plate 1, the auxiliary spring 2 and the top rod 7 in the first embodiment. The end surface of the ejector rod fixing plate is fixed with a withdrawal needle and a push plate 18, and the push plate is provided with a material withdrawal avoidance slot, and a cross bar 19 fixed on the support plate is inserted in the withdrawal avoidance slot. In the initial state, the ejector pin fixing plate 5 is attached to the shrinking die fixing plate 3, and the ejection needle is inserted into the shrinking die cavity. When the pallet moves to the left, the cross bar 19 is in the ejecting and avoiding empty grooves. It can be moved to the left until it reaches the left end of the withdrawal avoidance ...

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 ...
