Pipe/pile cage rolling welder machine

Pipe/pile rolling welder machine-Precast concrete Cage Welding Machine

As the key equipment for the production of pipe piles and electric poles, the roll welder for electric poles has undergone many years of modernization and has reached maturity and can basically meet the production requirements. However, there is still more room for improvement in terms of details, such as high energy consumption, large amount of consumables (copper plate), welding speed is not fast enough, long auxiliary time, high labor intensity of operators, as well as the short service life of individual mechanisms, welding quality needs to be improved. In this regard, for the above shortcomings, our company has achieved better results after a lot of practical research. In this paper, we explain how to reduce the energy consumption, improve the production efficiency and welding quality, and extend the durability of the equipment of the pole pile rolling welder.

Our company has made improvements in the following three aspects: improving welding speed, reducing auxiliary time and reducing manual operation.

Improving welding speed
One of the most effective ways to improve productivity is to increase welding speed, which is predicated on increasing the input density of welding current. The use of DC power source when the current is not zero point and not limited by the AC frequency, no alternating magnetic field generated, and can improve the density of input current, so the use of DC power source to further improve the welding speed. In addition, without increasing the power of the welding power supply, increase the welding circuit conductive area and cooling strength to prevent overheating of the circuit is also an effective way to improve the welding speed.

Adding automatic locking and unlocking device for steel rod ends on the tractor
The current production of electric pole pipe pile roll welder has realized the function of automatic locking and unlocking of steel skeleton end, with automatic unloading of steel skeleton and automatic return function of tractor car, only one person can operate to make steel skeleton, thus improving the production efficiency.

Application of automatic height-adjusting bracket cage
In the early stage, the height of the cage holder of the pipe pile roller welder was adjusted manually according to the current specifications of the steel skeleton, which required manual adjustment of the height of the cage holder every time the specifications were changed, which affected the production efficiency to a certain extent. The new cage carrier can adjust the height automatically, and the cage carrier can be adjusted automatically according to the bottom height of the steel skeleton when changing specifications, which saves the auxiliary time and further improves the production efficiency.

Automatic cage unloading device
After the Concrete Pipe Welding Machine is finished, the cage unloading flap automatically rises and the cage carrier then falls down to drop the welded steel skeleton onto the cage unloading flap, and the steel skeleton rolls down by its own gravity without human operation, which improves the production efficiency and reduces the labor intensity of the operator. skeleton.

Fast automatic return of the tractor
In the early days, the tractor of the Pole Cage Welding Machine for electric pole and pipe pile was mostly pushed back by human power, with low production efficiency and high labor intensity, while the rolling welder of the present production is mostly fast and automatic return, and there are also many enterprises to add automatic return device for the tractor of the early rolling welder itself, which improves the production efficiency.

Use the new type of bar piercing pipe
The roll welder for electric pole pile sets up the front and back of the two bar-wearing discs, and sets up the bar-wearing tube on the bar-wearing disc, which needs to be aligned twice to wear the steel bar to the predetermined position, taking up long time and low production efficiency, but now it is improved to the whole bar-wearing tube, which can wear the steel bar to the predetermined position only once, saving half of the time and further improving the production efficiency.

Large roll welder uses pneumatic positioning device on the top of the winding disc
Due to the large diameter of the winding disc of the large roll welder, when replacing the winding disc, the operator needs to climb up to the equipment to operate the positioning device of the winding disc, which is not only troublesome but also dangerous, but now it is improved to pneumatic positioning device, the operator only needs to press the pneumatic button to easily operate the positioning device of the winding disc on top of the equipment.
