grating welding machine

grating welding machine 1.power supply welding power: single phase AC 1000KVA/380V±5%/50HZ public power: three phases AC 50KVA/380V±5%/50HZ control power: single phase AC 50KVA/380V±5%/50HZ compress air supply supply pressure: ≥0.6MPa working pressure: ≥0.55MPa flow: ≥1m³/min air supply pipe dimension: ≥1/2 3. cooling water supply cooling water temperature: ≤30 flow: ≥500L/min pressure: ≥0.15Mpa supply pipe diameter: ≥4 drain pipe diameter: ≥6 function 2.1.1 There main press of this welder has one main hydraulic cylinder and four guide columns. The main pressure is adjusted and the max pressure is 100T. 2.1.2 The welding power is single phrase AC. 2.1.3 The cross rod is load one by one by manual and auto fed. 2.1.4 The flat bar is position in the starter by manual and auto cycle fed to the stop bar position. 2.1.5 There are two cross rods one weld time. We can make 4 type center dimension of cross rod. There are 38\50\66\100mm. 2.1.6 The straighten device is designed also. It is adjusted by manual first and auto working. 2.1.7 The operation console has two ways. Manual and auto operation method. 2.1.8 There are primary current and voltage display in power cabinet. 2.1.9 We adopt the PLC control. The parameter can be set in many steps. 2.1.10The panel out feed system is guided in line. 2.1.11 The guide comb is changed in one set. The change time is less then 30min. 2.2 technique parameter 2.2.1 flat bar suitable range item flat bar pitch3040flat bar(mm)height 20-6020-60thickness 2-52-5panel dimension(mm)Length 65006500width 992-995992-995cross rod(mm)cross section 4x4 5x5 6x6 4x4 5x5 6x6 length 1050 1050 pitch 33 50 66 100 Note: 1. the weld squire should be small than 1200mm2. 2. the min. close two flat bar center dimension is 25mm. 2.2.2 allowable material (flat bar) 2.2.2.1 Carbon steel and stainless steel 2.2.2.2 The dimension of the material should be fit for as follow. Otherwise it will cause the reduce the quality of grating. 2.2.2.2.1 flat bar Dimension(mm) allowable error thickness ±0.3 width±0.5(in the same panel should less than 0.5) 2.2.2.2.2 cross rod allowable error length: ≤±2mm line: ≤±1mm the diameter error of the cross rods in the same welding time: ≤0.2mm 2.2.3 grating panel dimension request 2.2.3.1 length ≤ 6000mm; the max. width :1010mm ; allowable error of panel width≤±5mm height range: 25-60mm 2.2.3.2 After weld the vertical error of the flat bar should be less then 10% of the flat bar width. 2.2.3.3 After weld the cross rod should be less then 1.0mm above the flat. 2.2.3.4 In 1500mm length of one panel, the distance error between the first cross rod with the last one should be less then ±5mm. 2.2.3.5 Other should be suit for the nation standard YB/T4001-98.
