coil Membrane Panel Production Line , System Tube Bending Machine

mainly used in the superheater, reheater, economizer serpentuator processing of large-capacity power plant boiler. This uses means of opening the upper die and lifting lower die. Angle control, pulse encoder; imported proportional valve controls the bending speed, boosting pressure; parameters can be controlled through the touch screen.

parameters:

technical requirements:

l Feeding tube means (choice)

l Tube is separable from the lower die and the upper die during transporting tube.

l Bending moment:Meeting the tube of length 60m, weight 1000kg bending requirement.

l Bending force:Meeting minimum bending radius requirement

l Blank holder device need be installed when processing thin-wall serpentuator.

l Blank holder device should be reasonable in structure and equipped with automatic lubrication device.

l The position of boosting clamp should be adjustable; the chuck position had better close the starting of bending.

l Bending tube program should store 15 sets

l The main components adopt imported brands (proportional valve, servos, PLC, input interface), which are available at home.

l Equipped with Oil temperature control system, which could regulate the oil temperature to ensure that keep 25℃～50℃through electric heating system and water cooling system.

l Bending process could be automatic, but it could also stop if needed at any time; manual control is fit to single action.

Acceptance criteria:

l Ovality : ≤10%

Ovality =2×(Dmax-Dmin)/(Dmax+Dmin)×100%

l Thinning volume

(t-t0)/t≤1/(4×R/D+2)

Where: t=tube thickness

t0=min thickness of outside elbow

R=elbow radius

D=tube diameter

l Other parameters of elbow should meet the JB/T1611 and UG0156 requirements

l Oval elbow, the thinning should not be less than the following requirements:
