Custom machine requirements

1. Workpiece data

Product Material：Carbon steel, stainless steel, aluminum, etc.

2. Welding robot workstation workflow

(1) First, the product to be welded is fixed on the platform, and then fixed with a special fixing fixture (the specific fixture is designed and manufactured by the customer). This ensures repeatable product installation.

(2) Obtain the required processing program in the control of the automatic vertical circular seam welding machine, and adjust the machine to the automatic mode.

(3) Press the start button on the machine, and then the machine automatically performs the position welding required for the workpiece.

(4) After the weldment is welded, the operator manually removes the product from the platform. Repeat the installation again.

(5) Repeat the above steps

3. Workpiece precision requirement：

（1）The surface of the work shall not affect the quality of welding oil, rust, moisture；

（2）Must not affect the positioning of burrs, etc.；

（3）The clearance shall be no more than 1mm；

（4）The consistency error of the same weld group is less than 0.5m。

1,Vertical ring seam automatic welding machine

KLTHG-LHF-900B is a product designed, manufactured and developed by our company. Used for circumferential seam welding or 3D arc welding of water tank flange nuts, cylinder inlet and outlet pipes, oil tank inlet and outlet, and hydraulic cylinder oil port.

The machine rotates the welding gun 360 °, and the workpiece is at a standstill. Welding of circular seams (including intersection lines) where the entrance and exit and water tanks, hydraulic cylinders and other vertical intersections are realized.

Model：KLTHG-LHF900B

KLTHG:Our company name(Kelite Weld)

LHF: Vertical ring seam automatic welding machine

900: The maximum diameter of the product is 900mm

B: This model is defined according to the structure

2,Introduction to Vertical ring seam automatic welding machine

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

2 .It is mainly driven by a stepper motor. The control system uses cnc controller and relay control

as auxiliary to realize automatic control of welding. The welding current and voltage can be set

directly on the operation panel. The machine has reliable quality, beautiful appearance and high

degree of automation.

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 Welding Drive Mechanism:

5.2.1 Automatic pneumatic lifting mechanism of the welding torch: It is composed of a bottom plate, a guide rail and a lifting cylinder. It can be used for up and down movement of the welding torch and resetting of the welding torch; the gun speed can be adjusted by raising and lowering the cylinder adjusting valve; the rotating speed of the welding torch can be set by the speed adjusting knob; the torch moves up and down, and the length of the welding torch is adjusted by the manual screw positioning.

5.2.2 Turning gun mechanism: It consists of a rotating gun shaft and a gear drive mechanism. DC Stepper motor drive, this machine uses the workpiece does not move, welding torch rotation welding.

5.2.3 up and down the gun fine-tuning mechanism (imitation mechanism): from the spring, the roller track up and down gun movement, with the gun movement to complete the welding torch's intersecting line track welding.

5.3 Pneumatic system: The device has an organic head cylinder. Supporting pneumatic components and solenoid valves are installed behind the equipment. When the equipment is working, make sure the air pressure is above 0.5Mpa.

5.4 The electronic control system is subdivided as follows:

5.4.1 Power Supply Part: Control Power Supply: Single Phase AC220V 50HZ; Welder Power Supply:AC 3×380V

5.4.2 Control Box:

The upper part of the control box is a button panel. All operations are performed on this panel. Electrical installation board: The electrical installation board is mainly composed of electrical components such as cnc welding controller , intermediate relay, and DC stepper motor driver. It connects and communicateswith the control buttons on the control panel through cables and wires to realize the control function of the machine.

5.5 Welding Power Supply: Configured according to customer requirements. For details, please refer to the manual of the welding power source.
