Automatic welding machine refers to the machine equipment that welds the annular gap. For example, the welds between the upper and lower covers of a household air-conditioning compressor and the housing are welded by a ring welder. Automatic welding machines are divided into vertical girth welding machines and horizontal welding machines. Generally, the welding machine used for the ring welding machine is gas shielded welding with automatic wire feeding. Next, by introducing the automatic welding machine provided by WINCOO, the application environment of the tank welding machine will be described in detail.

Research background of tank welding machine.
Metal pipe welding is an important part of aeroengine. Fuel, lubricating oil, air, oxygen and other working media in each system rely on metal pipes for transmission. Aviation engine pipeline parts have many types, large quantity, and high accuracy grade. Therefore, the requirements for manufacturing precision and quality are very high, and the requirements for manufacturing methods are getting higher and higher.
The main manufacturing method of metal conduit is tank welding machine welding. The welding of metal conduits of aero-engines mostly adopts manual argon arc welding, flame brazing, induction brazing, etc. The above-mentioned welding method is easy to operate, simple in equipment, low in cost, and low in requirement for a single welded pipe. Pipes, so it is widely used for pipe welding.
However, these welding methods are manual operations, which require very high skills for tank welders. Usually the weld formation is not ideal, and defects such as weld deviation, dents, weld leakage and incomplete welding will occur.
The application prospect of tank welding machine in the future.
In recent years, with the large-scale application of metal conduits, the welding quality requirements of metal conduits have become higher and higher, and the welding of automatic welding machines has become an ideal conduit welding method.
In the 1990s, there was an automatic girth welder for welding metal pipes. The diameter of the welded pipe could cover all the metal pipes on aero engines.Therefore, in recent years, automatic welding machines have been applied to the welding of metal conduits of aero-engines and have achieved success.
What are the application environments of tank welding machine?
In the operation of picking and exchanging electronic components, a tank welding machine welding process is required. Often in order to locate the problem of the circuit function, it is necessary to remove the components from the printed circuit board and perform the necessary measurements.
Generally, the reliable and successful operation of equipment related to space, defense, medical electronics, traffic control systems, communication systems, and supervision and control systems all rely on excellent tank welding machine welding.
1) Disassembly of extra components;
2) Inspection of components;
3) Exchange of defective components;
4) Check the circuit function.
The welding technology of the tank welding machine is an accompanying technology. With the development of the electronics industry, more useful packaging technologies and smaller components will certainly continue to appear, and tank welding machines will continue to be developed to meet the needs of the electronics industry and environmental issues. This is why for technology professors working in the electronics industry today, welding has become more and more professional!
I. Introduction
Plate rolling machine is a forging and pressing equipment.Plate rolling machine is mainly used in the field of cold machining of industrial containers and pressure tanks, etc.Required molding consistency, arcs are standard, good welding seam connection.Traditionally, industrial containers and tanks are formed by hand - by - hand, step - by - step, experience - operated roller.Due to the increasing demand for natural gas pipelines and oil tankers, traditional production has been unable to meet the requirements of the market.Fully automated machines are needed to realize large-scale industrial production.
II. Process analysis
Plate rolling process is a forming process that USES the plate rolling machine to make continuous 3-point bending of the plate. As shown in figure 1, the plate rolling process is composed of pre-bending -- centering -- coil circle --rounding
1. Pre-bending
Plate rolling, plate at both ends of a length, because the plate did not contact the roller, not bending, which is called the remaining straight side.In order to avoid the plate from the work roll out, the actual residual straight edge is often larger than the theoretical value.Because the remaining straight edge is difficult to eliminate in the straightening, and causes a large weld stress and equipment load, easy to produce quality and equipment accidents, so the sheet material must be pre-bending the plate edge before rolling, so that the remaining straight edge is close to the theoretical value.
2. Centering
The purpose of centering is to make the workpiece busbar parallel to the roll axis to prevent the occurrence of skew.
3. Coil circle
The method of rolling the circle is divided into one feeding and multiple feeding.
The rebound of cold coiling is remarkable, and a certain amount of over coiling is needed.
4. Rounding
Rounding is generally divided into three steps:
4.1.Loading.Adjust the roller to the required maximum corrected curvature according to experience or calculation;
4.2.Rounding.Roll the roller for 1-2 circles under straightening curvature (especially roll near the weld zone), so that the curvature of the whole circle is uniform;
4.3.Unloading.Gradually remove the load so that the workpiece rolls several times under gradually reduced corrective load.
III.Main structure and work principle
This machine is symmetrical rolling machine, down up roller and then let up and down roller do
opposite roll to bend steel plate.
B. This machine composed of two parts those are working part welded in whole chassis and moving part. Working part composed of left and right bearing base, one up roller, two bottom rollers (the material of the three rollers is 45#steel and do heat treatment), lifting screw and turbine and other accessory parts. Down rollers drive up roller to move, up roller can do up and down move by height way. Drive part composed of main motor, main speed reducer and other accessory parts.
C. Bottom rollers were drove by main motor through main speed reducer, output spindle of main speed reducer driven to two down rollers by one group gears, the revolve direction of rollers adjusted by main motor.
D. Upper roll lifted by accessory motor through vice speed reducer drive worm and worm wheel mechanism of right/left rolls bearing base. That to let the lifting pole do up and down move.
E. Unloading device is designed to remove the workpiece after drums bended into shape. Before unloading the upper rolls move to up limit position, the balance device on upper rolls ends hit upper rolls, draw out the spindle of the pin, then to remove the workpiece.
IV.Technical parameter
1.Universal upper roll rolling machine
2.Asymmetric plate rolling machine
3.Mechanical symmetrical plate rolling machine
4.Horizontal adjustable plate rolling machine
5.Four-rollers plate rolling machine
In today's international environment, oil is used more and more frequently, and its price is also rising. More and more producers, middlemen or users are building tanks to store oil.
