Applications

1，Vertical ring seam automatic welding machine

KLTHG-LHF-400(A/B/C/D)It is a product that our company designs, manufactures and develops. It is used for the circumferential seam welding of oil tank inlet/outlet ports. The machine uses a 360° rotation of the welding torch and the workpiece is stationary. The weldingof the circular seams(including intersecting lines) at the vertical intersection of the inlet/outlet port and the cylinder/cylinder is realized.

                                              Model：KLTHG-LHF400(A/B/C/D)

1)   KLTHG: Our company name(Kelite Weld)

2)   LHF: Vertical ring seam automatic welding machine   

3) 400: Lower cylinder diameter up to 400mm

4)   A/B/C/D: Refers to the machine's structural type and welding process

Remarks: Due to the large number of models of our company, if there are new models in the later stages of our company, we will explain the new quotation.

2，Introduction to Vertical ring seam automatic welding machine

1. Weldable materials include: 45#, 27SiMn, 35#, 20#, stainless steel, etc.;

2, the equipment is mainly suitable for the welding of cylinders and round nuts. The device is mainly driven by a stepper motor. The control system is supplemented by CNC programmable controller and relay control to achieve automatic welding control. The welding current voltage can be set directly on the operation panel. The quality of the whole machine is reliable, the appearance is beautiful, and the degree of automation is high.

3.The equipment has the functions of automatic lifting, automatic reset, automatic arc striking,etc.   It has a high degree of automation, a key operation, and stable and reliable operation. V-type thimble positioning mechanism is used for clamping to facilitate loading and unloading of workpieces.

4.For the intersecting line welds, the equipment is equipped with a mechanical copying mechanism.When welding the inlet/outlet port on the cylinder body, it is necessary to follow the contour heightdifference between the surface of the

joint and the cylinder so as to weld the intersecting line curve. Welding cylinder interface, equipped with two lifting V-shaped frame for supporting the cylinder block, under the V-frame roller, can be manually moved to facilitate the transposition. Under the fixture is equipped with an adjustable lifting platform.

5. Machine features

The device body has the following parts;

5.1 base and bed: bearing body, to bear the weight of the whole machine.

5.2 Cylinder Bracket: Used to support one end of the cylinder.

5.3 Welding drive mechanism:
5.3.1 Automatic pneumatic lifting mechanism of welding torch: It consists of bottom plate, guide rail and lifting cylinder. It can be used for the up and down movement of the welding torch and the reset of the torch; the speed of the gun can be adjusted by the lift cylinder regulating valve; the speed of the welding torch can be set by the speed control knob; the torch moves up and down, and the length of the welding gun is adjusted by manual screw positioning.
5.3.2 Rotating mechanism: It consists of a rotating gun shaft and a gear transmission mechanism. Stepper motor drive, the machine uses the workpiece does not move, the welding torch is rotated and welded.

5.3.3 Fine adjustment mechanism of the upper and lower guns (imitation mechanism): Move the gun rod up and down from the spring and the roller track, and complete the cross-track welding of the welding gun with the gun movement.

5.4 Pneumatic system: The device has an organic head cylinder. Supporting pneumatic components and solenoid valves are mounted behind the unit. When the equipment is working, ensure that the air pressure is higher than 0.5Mpa.
5.5 The electronic control system is subdivided as follows:
5.5.1 Power supply part: Control power supply: single-phase AC220V 50HZ; welder power supply: AC 3×380V

5.5.2 Control box:
The upper part of the control box is the button panel. All operations are performed on this panel. Electrical installation board: The electrical installation board is mainly composed of numerical control CNC controller, intermediate relay, stepper motor driver and other electrical components. It connects to and communicates with the control buttons on the control panel via cables and wires for machine control.

5.5 Welding power supply: According to customer requirements. See the welding power supply manual for details.
