Automatic Manipulator Welding Machine with Double Column for Pressure Vessel Production Line

Welding manipulator is a special equipment for automatic welding of internal and external ring joints, fillet welds and internal and external longitudinal joints of components combined with welding roller frame and welding positioner. It has a variety of structural forms such as fixed type, rotary type and all-position. According to the needs of users to choose the structure and supporting a variety of welding machines and increase tracking, swing, monitoring, flux recovery and transportation and other auxiliary functions.

Our company all types of welding mamipulator are using double-sided rectangular guide rail, stable and reliable guide. According to the requirements of welding process, SAW/TIG/MIG welding machine can be configured to form a welding center with welding rotator/positioner to realize automatic welding of circular seam and longitudinal seam of cylinder.

Major Component

1, Column: column is the main parts of the welding manipulator, usually using rectangular square pipe or bending welding structural parts, rigidity is very good.

2. Column slewing mechanism: column slewing adopts high-precision slewing bearing to ensure that the lower deflection of the transverse arm telescopic head is low. Column, slide seat, beam and other components can be rotated as a whole ±180°. Column rotation, split and electric two, can be manually or pneumatic lock, to ensure its safety and reliability.

3. Transverse arm: The transverse arm works smoothly and does not produce vibration and horizontal shaking that affect the welding quality. Transverse arm telescopic, column electric rotation, AC frequency converter speed regulation, the speed is stepless adjustable, digital display, preset parameters. Frequency converter has over current, over voltage, over moment protection.

4, Walking trolley: walking trolley adopts standard steel rail as walking track. The trolley is divided into manual and electric two kinds, the operation system is provided with a brake device, between the trolley and the track is provided with a clamp rail.

5. Skateboard components: skateboard components include skateboard body, regulating wheel assembly, anti-fall device, and crossarm drive component. The skateboard body is connected to the column assembly through the regulating wheel assembly, and the chain is connected with the anti-fall device to drive the skateboard assembly to lift.

6. Electric control cabinet: The electric control cabinet of the welding manipulator is equipped with control devices for lifting, lowering, extending and shrinking the beam. Its main function is thermal protection, over current protection, lack of phase protection, movement part of the limit protection function. The front door of the electric control cabinet is equipped with an operating switch.

Product Advantages

1, Adequate strength and stiffness. When the machine is put into use in production, it should withstand a variety of forces, so the machine should have enough strength and stiffness.

2, Reliability of welding. Welding cannot destroy the positioning position of the workpiece and ensure that the shape and size of the product meet the requirements of the drawing.

3, Flexibility of welding operation. The use of fixture production should ensure enough welding space, so that operators have a good vision and operating environment, so that the whole process of welding production in a stable working state.

4, With mechanical devices instead of manual assembly parts of the location, clamping and workpiece turnover and other heavy work, improve the working conditions of workers.

Product Features

1, According to the size and shape of the workpiece design.

2, Double rectangular guide rail, stable and reliable guide.

3, The main electrical components adopt the French Schneider brand.

4, With wireless control box.

5, There are lifting lugs on the base for easy lifting.

6, Post-welding heat treatment of main welding parts; Before painting, sand blasting and rust removal.

7, This product has reasonable design, stable operation and simple operation.

Technical Parameter

According to the bearing capacity of the transverse arm end, it can be divided into light type(LHQ), medium type(LH), heavy type(LHM) and Super heavy(LHW).

Each type of manipulator can be designed and manufactured according to customer requirements. Including manual movement manual slewing; Electric movement electric slewing; Manual walking or electric walking types.
