Description

Automatic pipe fitting machining system and automatic pipe fitting machining method

Technical Field

The invention relates to pipe fitting processing equipment, in particular to an automatic pipe fitting processing system and an automatic pipe fitting processing method.

Background

In the prior art, the pipe fitting can meet the requirements of high strength and light weight at the same time, so that the pipe fitting has wide application.

In the manufacture of the pipe fitting, the main process comprises the following steps: manufacturing pipes, sawing, bending pipes, opening grooves, welding, shaping, performing heat treatment and the like.

For the manufacture of pipes, it is usually done by a smelter, first smelting the ore into liquid metal, then cooling the liquid metal, then extruding the pipe in a corresponding die, during the extrusion process, continuously extruding or rolling to make the inside diameter, outside diameter and thickness of the pipe meet the requirements, the length of the extruded pipe can reach tens of meters.

Specially, in some processing enterprises, the strip can be purchased, then the strip is cut to enable the width of the strip to be matched with the circumference of the pipe, then two sides of the width direction of the strip are rolled, and finally the two sides of the width direction of the strip are welded to form the pipe. The length of the pipe can be set according to the length specification of the pipe.

For sawing, mainly sawing machines are used. The sawing machine can be used independently, and also can be directly arranged at the tail end of a pipe production line to realize line production, and the purpose is to cut off the pipe and facilitate subsequent processing.

In particular, at the end of the tube manufacturing process, a saw cut is added in order to remove the excess so that the end dimensions and shape of the tube conform to the drawing requirements.

For bending pipes, pipe bending machines are mainly used. The object to be processed by the pipe bender is a straight pipe produced by sawing, and the pipe bender bends the straight pipe into a specific shape, such as an L-shape, a C-shape, or an S-shape.

The number of times of pipe bending can be more than one, and the number and the type of the used pipe bending machines can be selected according to requirements.

For open-hole slots, the contents include drilling, grooving and threading to facilitate the connection and assembly of the pipe with other products. The equipment used is also very diverse, being able to be drilling machines, threading machines, punching machines, cutting machines and even machining centers.

For welding, it is often provided according to the customer's needs in order to increase the fixing points or to provide a product in which a plurality of pipes are welded together.

Thus, welding is not an essential step.

For the plastic, the main purpose is to make the shape and the size of the pipe fitting meet the requirements of a drawing, facilitate subsequent processing and ensure that the pipe fitting is qualified.

The shaping mode is also very various, but the shaping mode is usually applied by matching with a gauge. And when the detection is qualified, stopping shaping.

By heat treatment is meant the internal stress and strength of the pipe in a heated manner.

In order to improve the production efficiency, processing enterprises can optimize the part of the open hole groove, and generally, a robot or a manipulator is used, and the robot automatically carries out charging and discharging operations instead of manual charging and discharging.

However, in the existing application mode, the robot only saves the labor cost, and is difficult to consider both the equipment cost and the productivity.
