Embodiment Construction

[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0013] Such as figure 1 As shown, the sizing sleeve of the vacuum sizing mold applied to the billet tube according to the present invention has a sizing sleeve with four sides forming a rectangular shape, and the inner sides of the four sides facing the center 100 of the sizing cavity protrude to form an arc surface Protrusions 200, the inner sides of two adjacent protrusions are recessed toward the opposite direction of the shaping cavity center 100 at four corners to form an arc groove 300, and the arc surface protrusions 200 of the inner sides reach the shaping cavity center 100 The distance is greater than or equal to the distance from the arcuate protrusion 200 to the outer edge 400 . In addition, the connection between the arcuate protrus...

Abstract

The invention discloses a sizing sleeve of a vacuum sizing die applied to a billet tube. The sizing sleeve of the vacuum sizing die applied to the billet tube is characterized in that the sizing sleeve is a sizing cavity of which four sides form a rectangle; an inner side, which faces the center of the sizing cavity, of the four sides protrudes to form an arc bulge; inner sides of two adjacent bulges are recessed to the opposite direction of the center of the sizing cavity to form an arc groove at four corners; the distance from the arc bulge part of the inner side to the center of the sizing cavity is larger than or equal to the distance from the arc bulge to an outer side. The wall thickness of the billet tube can be reduced under the same ring stiffness condition, and original auxiliary materials are saved. Meanwhile, the surface of a winding pipe is smooth, and the construction quality is reliable.

Description

Technical field: [0001] The invention relates to a square billet tube of a hollow-wall wound pipe, in particular to a vacuum shaping die sizing sleeve applied to the square billet pipe of a hollow-wall wound pipe. Background technique: [0002] Hollow wall winding pipes commonly used in municipal engineering are mainly used as discharge pipes for municipal rainwater and sewage. It is a winding tube finished product formed by axially winding and welding the billet tube extruded by the vacuum shaping die of the billet tube on the winding forming table. [0003] At present, the calibrating sleeve of the vacuum shaping mold of the billet tube adopted has a square shaping cavity. In the process of extrusion and shaping of the blank tube, when the blank tube comes out of the sizing sleeve, due to the effect of vacuum and the blank tube itself has a certain hardness after the sizing sleeve is cooled, it still has a large plasticity. , the four sides of the blank tube are stretche...
