Abstract

A pipe contracting device comprises a pipe contracting mechanism, the pipe contracting mechanism comprises a horizontally arranged conveyor belt, a plurality of to-be-processed workpieces, which extend transversely and are perpendicular to the conveyor belt, are placed on the conveyor belt, pressing blocks are arranged above the conveyor belt at intervals and can downwardly compress the to-be-processed workpieces on the conveyor belt, side blocks, which can move to be close to or far away from the two end parts of the to-be-processed workpieces, are arranged on two sides of the conveyor belt, first through holes facing to the end parts of the to-be-processed workpieces are formed in the side blocks, the internal diameters of the first through holes are gradually reduced from the outside in, and when the side blocks move towards the end parts of the to-be-processed workpieces, the end parts of the to-be-processed workpieces are inserted into the first through holes. The pipe contracting device can not only accurately and quickly stretch and contract the end parts of the to-be-processed workpieces to be of relatively small apertures and simultaneously and quickly process the workpieces, but also automatically process and convey the workpieces, and is high in degree of automation and production efficiency.

Description

technical field [0001] The invention relates to a tube reducing device for reducing the end of a tube. Background technique [0002] Such as figure 1 , 2 As shown, many fields today, such as mounting brackets, or pipe fittings, etc., require the use of such pipe fittings as shown in the figure. Narrower shape, the overall thickness of the pipe is the same, but the inner diameter and outer diameter of the end are smaller than the inner diameter and outer diameter of the middle position. And some pipe fittings are also provided with threads on the outer surface of the end to facilitate the connection of multiple pipe fittings. Generally, the processing of this kind of pipe fittings requires the end to be stretched and shaped, the processing speed is slow, and it cannot be mass-produced, and the production efficiency is low. Therefore, there is an urgent need for a device capable of rapidly and accurately processing such pipe fittings in batches. Contents of the invention...
