Description

Technical Field

[0001] The present invention relates to the technical field related to steel pipe processing, and particularly relates to a multi-angle steel pipe beveling line-taking die. Background Art

[0002] A steel pipe bevel refers to a slope formed by processing and grinding the interface when pipes are welded. There are bevels of 45 degrees and 30 degrees. Before steel pipe welding, beveling treatment is usually required, that is, a bevel is processed on its end face. After processing the bevel on the end face, the welding performance can be well guaranteed.

[0003] When one end of a steel pipe needs to be connected to the surface of another building, in order to make the pipe orifice fit tightly with the surface of the building, a line-taking die is needed to draw the same shape as the building on the steel pipe orifice and then cut and connect it. For this reason, we propose a multi-angle steel pipe beveling line-taking die. Summary of the Invention

At the upper end of each support frame, a positioning cylinder is installed. A slide rail is movably installed inside the two movable frames. A die is arranged between the positioning cylinders, and a workpiece is arranged inside the die.

[0008] Further, a through groove is formed inside the movable frame, the slide rail is inserted into the through groove, and the slide rail forms a movable connection with the movable frame.

[0009] Further, the side wall at the upper end of the movable frame is rounded.

[0010] Further, a through slot is formed inside the slide rail.

[0011] Further, the inner diameter of the positioning cylinder is adapted to the outer diameter of the die, and the die is inserted into the positioning cylinder.

[0012] Further, a plurality of inclined grooves are uniformly formed on the circumferential outer wall of the die along the axial direction.

[0013] Further, a fastening bolt is provided on the outer side of each positioning cylinder and the movable frame, and a rotating handle is installed on the front of each fastening bolt.

[0016] Further, the movable frame, the support frame, the positioning cylinder and the mold are all made of stainless steel.
