A nozzle flaring and shrinking integrated machine

Abstract

The invention provides an integrated machine for flaring and shrinking a nozzle, comprising a body shell, a first motor is installed in the body shell, and a working cavity which is symmetrical about the left and right positions of the first motor and penetrates through the surface of the body shell is arranged in the body shell, The end face of the first motor is installed with a first transmission shaft extending into the working cavity, the end of the first transmission shaft is fixed with a first rotating block rotatably connected to the working cavity, and the first rotating block is provided with an opening facing away from the first motor. processing cavity; the first slider provided in the present invention can drive the shrinking splint to move under the driving of the second motor, so that the shrinking splint is pressed and contacted with the outer surface of the pipe fitting, and the pipe fitting is heated by the heat generated by friction, so that the pipe fitting is heated and softened, and then The necking splints continue to be close to each other to extrude the pipe fittings until the required necking diameter is obtained, which is to first use frictional heat to heat and soften the pipe fittings and then extrude the pipe fittings to obtain the required necking diameter.

Description

technical field [0001] The invention relates to the technical field of nozzle processing, in particular to an integrated machine for expanding and shrinking nozzles. Background technique [0002] Pipe fittings are used a lot in daily life. Pipe fittings can transport fluid substances such as liquids and gases, making life more convenient. During the process of connection and use of pipe fittings, due to the different diameters of pipe fittings, it is often necessary to expand and shrink the pipe fittings in order to Do docking. [0003] When the equipment in the prior art expands the pipe body, it can only expand the pipe opening to a certain size, and cannot adjust the enlarged diameter in real time. Flaring or shrinking, but it cannot be used for different pipe fittings, and different molds need to be replaced to process pipes of different diameters, which reduces the practicability. Some brittle pipes are prone to catastrophic damage, which reduces the quality of the pi...

Problems solved by technology

[0003] When the equipment in the prior art expands the pipe body, it can only expand the nozzle to a certain size, and cannot adjust the enlarged diameter in real time. For example, the reaming equipment in the patent CN202020201663. Expanding or shrinking, but it cannot be used for different pipe fittings. It is necessary to replace different molds to process pipes with different diameters, which reduces the practicability, and the pipe is cold expanded and contracted during reaming. For Some brittle pipes are prone to destructive damage, reducing the quality of the pipe, and the pipe fittings cannot be flaring and shrinking at the same time
