PW6 PTA Machine – Screw

Description

This equipment is mainly used for the equidistant, variable pitch, and surfacing of tapered screw cone parts. The specifications for its overlay welding are as follows:

• Screw length: max 5000mm
• Screw diameter: 30~400mm
• Screw segment: 15 segments, i.e. 15 segments of different pitch or diameter pitch welding on the same screw.

Main Functions

• Equal pitch welding
• Variable pitch welding
• Equal diameter welding
• Variable diameter welding

Main Components

• Arc ignition power supply: SanRex ID200 150A/60%        116A/100%
• Arcing power supply: Panasonic YC400 400A/60%        309A/100%
• Turntable (A-axis): Load-bearing 800 kg, CNC motor
• Oscillator: CNC motor, oscillating speed 360~2400 mm/min. The oscillating width is ±30 mm. The oscillating center adjustment range is 100 mm. Stay on both sides for 0.10~2.00 seconds. Oscillating parameter adjustment accuracy 0.25 mm
• Powder feeder: use transparent materials, the barrel can be loaded with 18 kg powder, DC servo motor control powder. The powder feeding range is 1~45 g/min. The powder feeding accuracy is 0.1 g.
• Control cabinet: The control cabinet is independent of the host and can be moved. It is convenient for users to make position adjustment according to the needs of the workplace.
• Remote control box: All the man-machine interfaces are collected on the mobile remote control box. The input and display of parameters are through a 10-inch touch screen display. The display has a large display window, clear font and long service life. With water flow display and setting function.
• PLC: Through the PLC to coordinate the work between the various components of the equipment, all welding parameters are stored inside the PLC. The large-capacity one-piece PLC can accommodate 90 sets of welding parameters.
• Three-dimensional beam: The movement range of the X-axis (left-right direction) is 5000mm, the speed range of the numerical control motor is 100~1000 mm/min, and the movement range of the Y-axis (front and rear) is 60 mm, which is manually adjusted. The movement range of the Z axis (up and down) is 400 mm, and the speed range of the CNC motor is 100~1000 mm/min.
• Welding torch: The maximum working current of the 600 type welding torch is 250A, 100%.
• Cooling water tank: Freon refrigeration, power 6000 calories/hour. The temperature control range is 5~30 degrees, stainless steel pump, 45 liter water tank.
• Protection system: The waterway protection system uses a wheeled flow sensor. When there is water flowing in the water pipe, the sensor senses the signal sent to the PLC and displays the water flow on the screen. When the water flow reaches the requirement, the welder can jobs. This is also a major feature of this equipment. The air pressure switch is equipped with a pneumatic switch in the air circuit. When the air pressure is insufficient, the welding machine stops working and the corresponding fault information is displayed on the display.

Installation Requirements

Following items should be prepared before installing:

• Power supply: 380VAC ± 10%, 65A air switch
• Gas supply: Pure argon in the bottled industry with a purity of 99.995%. An oxygen pressure reducing valve (low pressure range 0-4Kg/cm2) is also available.
• Provide 45 kg of deionized water.
• Solder powder: standard W grade (100/320 mesh)
