Abstract

The utility model relates to a machining tool, which is a round pipe arc port punching die. The die includes an upper die and a lower die. The die is characterized in that the upper die comprises a steel cylinder; an arc-shaped cutting edge is formed in the front end of the cylinder; a radial positioning hole is provided in the side wall of the cylinder at a position near the back; the lower die comprises a steel cuboid provided with a horizontally arranged central through hole; bolt holes are arranged on two sides of the central through hole; arc-shaped grooves are arranged in side walls of the cuboid on two ends of the central through hole; and the arc-shaped grooves vertically pass through the cuboid. The die is used to machine ends of round pipes subjected to butt welding. The die is good in product quality, high in size precision and production efficiency, convenient for butt welding, beautiful in look, and especially suitable for machining structural members of steel pipes.

Description

Pipe arc port blanking die
Technical field
The utility model relates to machining mould, especially a kind of pipe arc port blanking die.
Background technology
In the processing of steel member, often run into and have the structure of a steel pipe vertical welding on another steel pipe, attractive in appearance in order to weld, conventionally arc groove need to be made in the end of vertical tube.Traditional method is to adopt artificial oxygen welding cutting, and this method cut quality is poor, and not attractive in appearance, scale error is large, be unfavorable for follow-up welding, and production efficiency is low.
Summary of the invention
The purpose of this utility model will solve exactly and adopt artificial pipe cutting termination of poor quality, and scale error is large, is unfavorable for follow-up welding, and the problem that production efficiency is low provides a kind of pipe arc port blanking die.
Concrete scheme of the present utility model is: pipe arc port blanking die, include upper die and lower die, and it is characterized in that: described patrix has steel cylinder, be shaped with the circular arc edge of a knife at cylindrical front end, have radial location hole in cylindrical sidewall by rear portion; Described counterdie has steel cuboid, has horizontally disposed central through hole on cuboid, is positioned at central through hole both sides and also has bolt hole, is positioned on the two ends sidewall of central through hole has circular groove at cuboid, and circular groove vertically runs through cuboid.
Its arc radius of the circular arc edge of a knife of patrix described in the utility model equals workpiece pipe external diameter R.
The central through hole of counterdie described in the utility model equals workpiece pipe external diameter R+ (1~2) mm, and the circular groove radius in counterdie equals workpiece pipe external diameter R+0.5mm, and the degree of depth equals workpiece pipe external diameter R's.
The utility model is loaded on punch press while use, steel pipe is installed in counterdie central through hole, and makes steel tube end part concordant with counterdie lateral wall, starts upper die of punching press descending cutting, and getting final product punching, to go out quality good, the circular arc recess that dimensional accuracy is high.
Application the utility model processing butt-welded tube end, production efficiency is high, good product quality, dimensional accuracy is high, and good looking appearance facilitates follow-up welding, and weld size is unified, and precision is high, saves scolder.
