Side skin stretching machine

Side skin tensioning equipment, as an important part of the bus welding process, plays a decisive role in the appearance quality of the bus body in the entire bus welding process. It is divided into bus side skin electric heating stretching equipment and bus split (integrated type) side wall skin cold stretching equipment. Both types of devices have their own independent characteristics.

Electric heating tension equipment

Features: Good stretching effect, simple equipment installation requirements.

Description: The electric heating stretching equipment for the side skin of the bus uses electric heating to soften the skin, and then tightens the skin with a pneumatic chuck, so as to achieve the effect of stretching the skin. This process has a relatively high elongation rate , After tightening, the effect of rising and pulling is good. The electric heating stretching equipment for the side skin of the bus is installed in the steel structure of the gantry, which is less dependent on the foundation.

Cold stretching equipment

Features: strong compatibility, energy saving

Description: The split-type side wall skin cold stretching equipment for bus uses the tension force of the oil cylinder to cause slight plastic deformation of the skin so as to achieve the effect of skin stretching. Compared with the electric heating stretching equipment for the side skin of the bus, the cold stretching equipment for the split side skin of the bus does not need to be energized and heated, and the split type cold stretching equipment for the side skin of the bus can perform the stretching work of the aluminum skin, and It does not need electric heating, which is relatively more energy-saving.
