Method for bending metal pipe as well as equipment for implementing method

Abstract

The invention discloses a method for bending a metal pipe. The method comprises the following steps: an upper mould is prepared and comprises a fixing board, a connecting piece and a mould head, and a first groove, which extends to the inner wall of the mould head and is used for performing the metal pipe bending operation, is formed in the lower surface of the mould head; a lower mould is prepared, a second groove is formed in the upper surface of each of a left articulation piece, a middle movement piece and a right articulation piece of the lower mould, and the three second grooves are linearly arranged and correspond to the first groove; and the lower mould is arranged below the upper mould, the metal pipe is arranged in the second grooves to be positioned, pressure output equipment is controlled to enable the upper mould to move downwards, and at the moment, the left end of the metal pipe is pressed upwards to be bent under the coordination of the left end of the first groove and the second groove on the left articulation piece, and the right end of the metal pipe is pressed upwards to be bent under the coordination of the right end of the first groove and the second groove on the right articulation piece. The invention further discloses a piece of equipment for implementing the method for bending the metal pipe.

Description

technical field [0001] The present invention relates to deep fryers and in particular to a method of bending metal tubes and a device for carrying out the method. Background technique [0002] In modern society, metal pipes are a very commonly used item, usually used to transport liquids, gases or components for building structures. When using metal pipes, it is usually necessary to bend the metal pipes and apply the bent metal pipes to corners. A conventional method for bending a metal pipe is to use a simple mold to fix one end of the metal pipe, fix the other end to a rotatable device, and rotate the transposition to achieve the purpose of bending the metal pipe. This method is simple and easy to operate, and it is currently a commonly used method for bending a small number of metal pipes. However, this method of bending metal is not accurate enough, and the bending angle of the metal pipe is difficult to control, and such bending metal pipe operation requires the perso...
