Below the operation report after both-end pressure touch welding machine butt welding wire rod:
One, service time
In January, 2013-so far for L1, L2 wire drawing machine
Two, on-the-spot employee's service condition investigation
Wire-drawing operation work generally reflects that both-end pressure touch welding machine is simple to operate, one-shot forming and also drawing continuous.And original machine of meeting and discussing is clean to the head dummy of wire rod butt-joint, end face, whether two ends wire rod etc. requires higher point-blank, operative employee will spend many energy on meeting and discussing, generally speaking, both-end pressure touch welding machine compares welcomes by wire drawing operative employee, and cutting payroll to improve efficiency to company's wire drawing in addition also provides support.
Three, Data Comparison
1, drawing process
It is do plumb joint tension test that the most direct method of first welding quality is coiled in measurement, judge according to hot strength and fracture apperance, the ratio being greater than 90% dish unit intensity by the plumb joint tension test intensity that the common machine of meeting and discussing did in the past is about 60%, fracture apperance is without constriction, and easily produce weld defect, such as welding edge burning.90% is surpassed by two forging and stamping ratio that machine plumb joint tension test intensity is greater than 90% dish unit of meeting and discussing, and fracture apperance all slightly constriction, one-shot forming.
Because allowed the first butt joint of dish exist and do not need to remove in steel strand wires national standard, if plumb joint has broken in twisting process, stop except process except causing, the length that also can have influence on whole group of steel strand wires is reached, and causes the heavy steel strand wires (being less than 1.5 tons) of shallow bid.Between the importance of welding quality to twisting process, the welding quality that we judge in a period of time with the number of times (breaks/output * 100) of each hundred tons of plumb joint fracture is good and bad:
Wherein: L1, L2 wire drawing machine has obvious reduction at the fracture of wire number of times of rear road twisting operation, 1-4 month L1 in 2013 on average every hundred tons of broken end number of times reduces to 19.5% of the same period last year, L2 reduces to 16.4%, L1, L2 1-4 in this year month fracture of wire 17 times altogether, less 59 times compared with the same period of last year, within 30 minutes, calculate by each average treatment of twisting fracture of wire, can directly reduce because these two wire drawing machinees break end the down time that causes 1770 minutes, average monthly 590 minutes, directly affect monthly output 74 tons.Pull off scrap wire 120 meters calculating by each fracture of wire, on average monthly reduce by about 3 tons of waste silks (60%), the whole year in 2012, because fracture of wire causes disconnected cambered plate 83, adds up to 60408 yuan, and within 2013, so far only with cambered plate 6, estimating only breaks can save 50,000 yuan in 1 year of bow.
Four, conclusion
1, both-end pressure touch welding machine compares and welcomes by execute-in-place work, and it is simple to operate, success rate is high, and to minimizing down time, improving production efficiency plays an important role.
2, after employing both-end pressure touch welding machine, rear road fracture of wire probability reduces by more than 80%, and twisting scrap wire waste silk reduces 60%, and the equipment fault caused of breaking end reduces about 75%, and the maintenance cost that broken end causes reduces the disconnected bow of about 86%(and is reduced to about 1 piece/month from 7 pieces/month).
