Single-centre die used for machining copper pipe

Abstract

The invention discloses a single-centre die used for machining a copper pipe. According to the structure, a first U-shaped groove and a second U-shaped groove are formed in a lower die body, and a third U-shaped groove and a fourth U-shaped groove are formed in an upper die body. The first U-shaped groove and the second U-shaped groove are symmetric. The third U-shaped groove and the fourth U-shaped groove are symmetric. The first U-shaped groove corresponds to the third U-shaped groove in position, and a first U-shaped pipe die body is formed. The second U-shaped groove corresponds to the fourth U-shaped groove in position, and a second U-shaped pipe die body is formed. A first ejector block and a second ejector block are arranged on the two sides of the lower die body, and a first ejector block and a second ejector block are arranged on the two sides of the upper die body. Each first ejector block is provided with a plurality of parallel first centres. The first centres correspond to the end portion of an opening section of the first U-shaped pipe die body. Each second ejector block is provided with a plurality of parallel second centres, and the second centres correspond to the end portion of an opening section of the second U-shaped pipe die body. The first centres and the second centres are the same in number, and the center bent position of each of the first U-shaped groove and the second U-shaped groove is provided with a cavity. The single-centre die has the beneficial effects that the structure is simple and effective, the machining efficiency is high, time is saved, and the produced special-shaped U-shaped copper pipe is stable in structure, not prone to deformation or damage and very suitable for production and popularization.

Description

technical field [0001] The invention relates to a single thimble mold for processing copper pipes, in particular to a single thimble mold for processing special-shaped U-shaped copper pipes. Background technique [0002] In the prior art, when processing special-shaped U-shaped copper tubes, the special-shaped structure and U-shaped copper tubes are generally connected together by welding to obtain special-shaped U-shaped copper tubes.
