C Tube Bending Membrane Panel Production Line Heat Resistant

C Tube Bending Membrane Panel Production Line Heat Resistant

(Ⅰ)Characteristics

The device is provided by the way of opened the up mold and up/down of the under mold. Which is very convenient for Small system of R elbow bend demoulding. Point of control, the use of pulse encoder, speed bends, booster pressure with import proportional valve . Parameters set by the touch screen.

(Ⅱ)purpose

A The device is mainly used in the superheater, reheater, economizer sperpetuator processing of large-capacity power plant boiler .

B Pipe materials are carbon steel (20G, SA210A, SA178C, etc.), heat-resistant alloy steel (15CrMo, 12Cr1MoV, SA213-T12, T22, T23, T91, T92, T122, etc.), stainless steel (SA213-TP304H, TP321H, TP347H , thin fine-grained TP347HFG) and so on.

C Pipe specifications: Outside diameter: Φ32 ~ Φ76

Thickness: 3.5 ~ 14mm

D The machine is equipped with serpentuator production line

Ⅲthe technical requirements and the main technical specifications:

(Ⅰ)the main parameters of CNC hydraulic boosting bender :

A Pipe outside diameter: Φ32 ~ Φ76

B Thickness: 3.5 ~ 14.0mm

C Bend radius: 32 ~ R250

D Bend radius: When t / D ≥ 0.1 , R / D = 1.2

E Bending angle: Product bending angle: 180 °

F Machine available bend angle: 195 °

G Machine bending angle precision: ± 0.1 °

H Bending speed: 1 ~ 4rpm, return 4rpm

I Pipe material: carbon steel, low alloy steel, heat-resistant alloy steel, stainless steel

J Length of jointed straight pipe : 30m ~ 90m

K Feeding: Feeding CNC, which give directions by means of CNC system of bending machine, loading from bender racks to the feeding apparatus. Feeding length of a time: the greatest ≥ 20 m (using the wheel feed)

a Feeding speed: 40m/min ~ 0.5m/min adjustable

b Feed accuracy: ± 1mm/10m, NC feed length of a time> 19 meters (the length of open-feed)

L Minimum straight section between two adjacent elbows: 100mm

M Bending Moment: 8t.m. the largest bending capacity of pipe should take tube row length of 19m and total length of 90m .etc factors into consideration .

N Bending method: cold boosting

a Heading force : 0 ~ 25t, Be adjustable at different bending angle and pre-selected to meet with different angles of a pipe

b Boosting stroke: 700mm

c booster clamp can be block-level regulation. Bending mode can be divided into two halves for the whole ceremony, the net clearance should not be less than 80mm after the separation.Machine lathe bed structure can satisfy serpentuator process with more than 180 ° or flush a number of different angles. The distance between CNC feeding device and the center of bending pipe: ≤ 2.5 meters.

O Control System: CNC

P Bending direction: turn left or right turn without artificial external force to finish a one-time bending .

Q the control of bend mechanism:

a. the multi-casing pipe row of all the drawing information could be input: such as the bending angle, straight length.

b. all action involved bending production can be controlled, including kicking-off, feeding, clamping, mode, bending, boosting and so on.. which could connect smoothly.

(Ⅱ)Elbow evaluation criteria:

A roundness≤ 10%

Dmax-Dmin

Roundness = 2x ------------------------------ x100%

Dmax + Dmin

Where: Dmax ----- the largest diameter of bend , mm;

Dmin ----- the smallest diameter on the Dmax transverse plane ;mm;

B any point of minimum diameter Dmin of bend calculated by the following formula:

Dmin ≥ 0.895Dw +0.233 t (t- minimum wall thickness of straight tube , Dw- outside diameter nominally of straight pipe );

C R = 1.2D bend allow the wall thinning Department:

Lateral to allow thinning : Sa ≥ S × (1-10%)

Where: Sa-elbow lateral wall thickness;

S- straight tube actually radius

D The system has a comprehensive fault self-diagnosis function, which could display the fault code and the status of monitoring the I / 0 of PLC.

E all kind of workpiece on the device platform have Chinese logo or graphic logo:

F The equipment should be operated in two operation ways converted between each other.

a semi-automatic: this mode of operation can achieve step-by-step operation automatically.

b manually: Every action must be based on the corresponding button.

G The procedure should take the necessary interlocking and joint function into consideration to ensure operator and equipment safety.

H pneumatic circuit designed by 4Kg/cm2 pressure

I R = 40 ~ 250 serpentuator tube bended automatically.

J oval elbow, the thinning should not be less than the following requirements:
