【概要描述】In the production process of welded pipe, there is a close matching relationship between used welded pipe machine and flat head machine. The following are the specific correlations and interactions between the two: 1. Process chain coordination After the used pipe welding machine completes the forming and welding of the metal strip, the flat head machine, as the terminal processing equipment, is responsible for precision cutting of the welded pipe port. The two are connected in series through the transfer track to form a complete "roll-weld-finishing" production line. Statistics show that the use of second-hand pipe welding machine supporting flat head machine can increase the pipe pass rate by 23%, and the end perpendicularity error is controlled within 0.15mm. 2. Device compatibility requirements When purchasing a used pipe welding machine, it is necessary to focus on checking the adaptation parameters of the flat head machine: including the transmission speed matching degree (recommended error < 5%), the center high alignment accuracy (±0.5mm), and the compatibility of the clamping mechanism. There have been cases of abnormal tool wear of flat head machine due to the instability of output speed of used pipe welding machine (fluctuation > 8%). 3. Combination of cost control advantages The used pipe welding machine procurement cost is about 40-60% of the new machine, and the refurbished flat head machine can further save 35% equipment investment. However, it should be noted that the energy consumption of the used equipment portfolio is usually 18-25% higher than that of the new intelligent equipment, and an energy efficiency assessment is recommended. 4. Maintenance and management linkage There is a strong correlation between the maintenance cycle of the two, for example, when the roll of the welding machine is replaced, it is necessary to calibrate the flat head machine guide device simultaneously. The practice of a steel pipe plant shows that the establishment of linkage maintenance system can increase the comprehensive utilization rate of equipment from 76% to 89%. 5. Space for technological transformation When the used pipe welding machine is installed with PLC control system, it is recommended to upgrade the servo drive module of the flat head machine simultaneously, which can increase the degree of automation of the whole line to more than 85% and increase the production of the shift by 30%. In a renovation case, after the installation of the visual inspection system, the scrap rate of the flat head process was reduced from 1.2% to 0.3%. It is necessary to pay special attention to that in the combination of used pipe welding machine and flat head machine, the age difference of the equipment should be controlled within 5 years, otherwise it is prone to compatibility problems caused by technical generation differences. It is recommended to require suppliers to provide at least 3 months of process commissioning service period when purchasing.
