Functions

By learning the advanced technology from foreign countries, we developed HGK model rotators according to the ZBJ3303-90 stardard of mechanism industry of Peoples Republic of China. They are widely used in automatic welding of round or ring metal, and  they are also an ideal equipment in pressure vessel manufacturing field. They have reliable quality, advanced functions and are easily operated. 

Structure and principle

HGK models are adjustable welding rotators.Every model consists of two parts:initiative part and passive part. The two speed reducers,which make the initiative rollers rotate,work together at the same time to achieve the stepless speed controlling through the frequency converters. The working piece rotates stably.The speed of rotating of working piece is 6-60m/h.It can meet the requirement of all kinds of welding.

Installation instruction

The part with motor and the part without motor shoud be installed on the same level. The rollers should be in a horizontal line,and the centers should be in one line.The bottom should fully touch the gound.

Operating instruction

1. Before starting,please put oil to the speed reducer. The primary speed reducer can be added thin oil and the secondary speed reducer can be added grease(thick oil).

2. After starting the machine, if there is sound or vibration, please eliminate the fault by doing as follows: put the working piece on the rotator to check if the position of working piece is proper, if the working piece keeps close to the rollers, if there are things in the way of rotating. After everything goes well, the machine can be operated.

3. When starting the motor, please turn off the switches on the controller, and turn the bottom of speed to the min. in order to reduce the electric current.

4. If manual welding needs to be done, please take out the controlling switch according to the electrical drawing. It can be held in hands or fixed on the helmet when welding. Please make sure the “clockwise” orcounter-clockwise shut up.

Maintenance

Please check and remove the obstacle on the machine before using. Please make sure there are people specialised in maintenanceRubber rollers can not touch oil or be put in high temperature condition.


Note: Regarding to screw mandrel adjusting rotators, dowel pin needs to be taken out before adjusting the central distance. The dowel pin can be taked back after the central distance is finished adjusting. Otherwise,the screw mandrel will be destroyed.
