Embodiment

[0052] figure 1 A schematic structural view of the first state of the elbow split mold 100 provided by the embodiment of the present application is shown, figure 2 It shows a schematic structural view of the second state of the elbow split mold 100 provided by the embodiment of the present application, image 3 It shows a structural schematic diagram of another angle of view of the second state of the elbow split mold 100 provided by the embodiment of the present application, please refer to Figure 1-Figure 3 , this embodiment provides a bent pipe split mold 100, which is mainly used for pressing straight pipes into bent pipes. Elbows can be used to make elbows.

[0053] The parting surface of the elbow split mold 100 is a curved surface. The "curved surface" refers to a surface that is different from a plane. The shape of the curved surface can be set according to the shape of the target elbow. This application does not limit the specific shape of the curved surface .

Abstract

The invention relates to the field of bend pipe processing, and in particular to a bend pipe split mold and a bend pipe manufacturing method. The parting surface of the bend pipe split mold is a curved surface, and the bend pipe split mold is provided with a mold cavity extending in a first direction, and the bend pipe split mold comprises a base body, an upper mold and a lower mold assembly; thelower mold assembly comprises a fixed lower mold and a first sliding lower mold; the first sliding lower mold is provided with a first guiding part; the upper mole is provided with a second guiding part matching with the first guiding part, and when the upper mold is descending, the first guiding part can abut against the second guiding part and move oppositely so that the first sliding lower moldis close to the fixed lower mold and closes the mold. When the upper mold presses a straight pipe, the first sliding lower mold and the fixed lower mold are close to each other, and during the process of closing to each other, the bending stress of the straight pipe is released. The bend pipe split mold and the bend pipe manufacturing method can eliminate stress concentration, improve the uneventhickness of the bend pipe and improve the quality of the bend pipe.

Description

technical field [0001] The present application relates to the field of pipe bending processing, in particular, to a pipe bending split mold and a pipe bending manufacturing method. Background technique [0002] In the prior art, most of the bent pipes are formed by pressing straight pipes, but during the pressing process, the stresses at different positions along the length direction of the pipe body are different, and the pressing is difficult to control. Large differences in wall thickness and other issues. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a split pipe bend mold and a method for manufacturing the bend pipe, which aims to improve the problem of poor quality of the bend pipe pressed by the existing pipe bend mold. [0004] The first aspect of the present application provides an elbow split mold. The parting surface of the elbow split mold is a curved surface, and the elbow split mold is provided wit...
