Embodiment Construction

[0024] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0025] A kind of T type large-diameter composite tee process, it specifically comprises the following steps:

[0026] Step 1: Use the composite tube blank as the material for the tee joint, and determine the size of the composite tube blank by the coefficient of the finished tee;

[0027] Step 2: If figure 1 As shown, when the tube blank 1 is placed horizontally, the upper half of the tube blank is completely wrapped inside and outside with a heat insulating material 8;

[0028] Step 3: According to different substrate tube materials, heat the lower half of the tube blank to 700°C-900°C;

[0029] Step 4: If figure 2 and 3 As shown, the heat insulating material 8 is removed, and the heated tube blank 1 is placed on the first set of molds. The first set of molds is composed of an upper mold 3 and a lower mold 2. A T is arranged in the middle of the f...

Abstract

The invention discloses a T-shaped large-diameter composite tee joint technology. According to the technology method, multiple sets of dies are adopted for pressing a composite tee joint step by step, so that the deformation of each pressing is reduced, the occurrence of defects such as bulge and collapse is greatly reduced, and the molding quality of the composite tee joint is guaranteed. According to the invention, the multiple sets of dies are adopted for pressing the composite tee joint step by step, so that the deformation of each pressing is reduced, the occurrence of defects such as bulge and collapse is greatly reduced, the flow direction of branch pipe metal is precisely controlled, and the conditions that the molding quality of the composite tee joint is high, the wall thickness of an R arc is not thinned, composite layers of a branch pipe and a main pipe are not layered, and the main pipe does not swell can be guaranteed. The pressing work procedure of the composite tee joint can be detailed by adopting the multiple sets of dies for pressing step by step, and the technical ability requirement of an operator can be reduced.

Description

technical field [0001] The invention relates to a T-shaped large-diameter composite tee process. Background technique [0002] It is difficult to press and form large-diameter composite tees with single weld seam, which has always restricted the production of large-diameter composite tees. It is produced by traditional technology, using a set of molds for pressing, and the amount of deformation is large during the pressing process, and the multi-layer is prone to defects such as bulges, collapses, and wrinkles. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a T-shaped large-diameter composite tee process, which uses multiple sets of molds to gradually compress the composite tee, thereby reducing the deformation of each pressing and greatly reducing the The occurrence of defects such as bulges and collapses is reduced, thereby ensuring the molding quality of the composite tee. [0004] In order to...
