1.host equipment parameters and development instructions：

1.1 Machine characteristics：

KLTHG-ZF-**** A Longitudinal seam welding machine consists of base, cantilever bracket, pneumatic lock keychain, support mandrel, beam support, walking drive, wire feeder, cable assembly, air pipe, pipe, CNC welding Controller and other major mechanical parts. It is equipped with a special welding torch holder (3D manual adjustment) suitable for: (CO2 / MAG / MIG / TIG / plasma);

   It also has dedicated up / down / front and rear electric slide tables to realize torch swing welding, TIG / plasma arc length tracking device.

1.2 Structural features:

1.2.1 Machine base

   Base for the steel structure, with sufficient rigidity and strength, to meet the requirements of the whole machine, the foot can be fixed with anchor bolts on the foundation.

1.2.2 Key holder

The key holder is symmetrical two sets, which can exert pressure on both sides of the longitudinal seam respectively. The fixture is installed on the base, the clamping device of the key-type fixture is the compressed air leading to the airbag, the airbag is inflated and pressed to the lever mechanism, so that the maximum pressure at the pressure finger end is 30Kgf / cm (0.6Mpa) Adjustments are usually made at 7-30 Kgf / cm (unilateral). Pressure finger width of 75mm, made of copper alloy, can be positive and negative use on both sides to extend the service life. The fixture is mainly used for welding the outer seam of the cylinder, and can also be used for the inner seam welding of the large-diameter cylinder.

The operation of the clamping device is to control the clamping or release of the left and right pressure fingers respectively through the buttons on the wire-control button box.

Pressure finger width adjustment. If the workpiece plate thickness difference is small, generally do not need to adjust the width of the pressure finger, if the need for operation, adjust the rear plate support plate adjustment screw can change the width of the pressure finger to meet the different thickness of the welding process on the pressure finger Wide demand.

1.2.3, Mandrel

The mandrel is a hollow square body or a circle, with a copper pad (pad) on it, which is clamped and fixed together with the piano type pressure finger. Gasket on the back of the molding groove, the hole through the small holes to protect the gas. For special materials, molding tank can be installed brass, copper liner for ease of cooling. Adjustable vertical distance between the liner and the pressure finger on the mandrel, the size of which can be adjusted according to the thickness of the weldment, the adjustable range is 30mm.

1.2.4, Bracket

Bracket mounted on the end of the clamp body is a device that connects the key holder and the spindle. The structure of the frame shape, through the lower end of the mandrel bolt adjustment, the mandrel and the pressure finger spacing in the horizontal axis parallel. In welding, the bracket turned upside down, the weldment was loaded, the bracket turned down and locked. Only lock the mandrel under the bracket.

1.2.5, Beams, trolley

On the main body of the left-hand fixture to fix the beam, on the side of the beam, there is a linear guide rail, and a rack is installed on the top. The trolley is run by a DC stepper motor , and then linear motion is achieved by the gear and rack. The motor adopts digital pulse stepless speed regulation, and the trolley speed is 100 ~ 1000mm / min. When you need to move the car fast, you can move the car's front handle plate-type, release the gears and racks, and you can push the car to move fast (manually). The maximum travel limit is controlled by a travel switch. Mechanical stops are installed at both ends of the rail to ensure that the trolley does not slide out of the rail.

1.2.6, Gas system

Compressed air system installed in the base cavity, by the filter (2 groups, respectively), pressure relief valve. Pressure gauge and solenoid valve and other components. In normal use, the pressure regulator valve adjusted to 0.3 ~ 0.6Mpa, when using a small mandrel welding, the lower pressure should be used.

1.2.6 PLC controller

It is equipped with 3.5 inch color screen, RS 485 communication, Chinese/ English Switch, and USB connection. It is highly reliable, highly accurate, low noise and easy to use.
