The bending pipe welding machine is suitable for the welding application of the inner and outer arc of the stamping attachment of the land circular air pipe. The welding control unit and other aspects of the man-machine interface of the equipment are independently developed and designed, including the important welding elements such as welding current and speed,and the digital display of the man-machine interface is fully realized.And for the welding characteristics of galvanized sheet steel, in the welding control of the design of a unique welding curve, so that it can be more reliable to complete the professional needs of galvanized sheet welding.

The uncoiling and leveling production line is used for various roll bending processes. After uncoiling, leveling, and cutting, flat sheets of the required width and length can be obtained. The production line consists of a feeding rack, uncoiler, leveler, conveyor, guide device, length fixing device, plastic cover plate device, shearer, and conveyor table.

Angle iron flange punching and cutting including total 5 parts: Feeding device, major part, cutting device, hydraulic and electric system. PLC control system can improve accuracy , more effective and lower cost.

  Product features: copper crankshaft structure, rigid key clutch,two hands protection starting device, automatic oiler, automatic cylindercontrol switch.Different molds choose diferent punch presses,semi-automatic molds. full automaticmolds (including feeding rack, leveling machine, servo feeding) 40 Ton TDF automatic corner punching machine video： 63 TON TDC automatic corner punching machine video： 名称 Description 技术参数 Specification 型号 Type JG23-40D JC23-63D J23-80D 公称力 Nominal force kN 400 630 800 滑块行程 Slide stroke mm 20-120 20-120 10-130 行程次数 SPM min⁻¹ 55 55 50 最大装模高度 Max die height mm 210 220 270 装模高度调节量 Die height adjustment mm 70 80 80 工作台板尺寸（前后×左右） Bolster(F·B×L·R) mm 400×660 450×700 480×780 工作台板落料孔尺寸（上孔直径×深度×下孔直径） Bolster opening(up dia × depth × low dia) mm Φ220×25×Φ180 Φ200×45×Φ180 Φ200×45×Φ180 工作台板厚度 Bolster thickness mm 80 90 100 机身工作台孔尺寸（直径×前后×左右） Bed opening(Dia×F·B×L·R) mm Φ200×150×300 Φ250×200×340 Φ250×200×340 模柄孔尺寸（直径×深度） Shank hole (Dia×Depth) mm Φ50×70 Φ50×80 Φ60×75 立柱间的距离 Bettween columns mm 250 280 320 主电机功率 Main motor power kW 3 4 5.5 外形尺寸（前后×左右×高） Outline dimension(F·B×L·R×H) mm 1200×1100×2300 1500×1300×2500 1800×1600×2650 重量 Weight(KG) 2500 3200 4200

Theconducive electrode of the welding machine adopts South Korea's high conduetivitycopper eleclrode malerial, which makes the welding current uüilization ratio noreefficient. The important welding elements sucl as welding piessure realize the digialdisplay of man-machine interface, and acaiding to the welling characterisics of galvanizec sheet steel. a unique welding curve is designed in welding control so as to more reliably complete the professional needs of gelkanized shee welding.
