Quality Shandong hydraulic flanging machine, hydraulic four-poster flanging machine car muffler processing 
 Flanging machines 
 A. The use of the machine 
 This machine is used after processing by the volume barrel spot car muffler round shell, to be pressed after both ends of the oval flange stereotypes in this machine. Also be used for the above sectional shape of the muffler shell and other thin metal parts, non-pressure type, both ends flanged. 
 Two. The characteristics of the machine: 
 This machine automatically feeding and back feeding device, with manual loading and unloading shells, parts and accessories suitable for multi-species processing muffler. 
 This machine is to be adjusted manually and automatically cycle the two processes work. Automatic circulating simply the workpiece placed on stepping up the mold, pressing the automatic cycle button or foot pedal switch, can achieve automatic processing program. In addition to the upper and lower shell outside the artificial, the other automatically processed into the desired pressure-shaped flange parts. 
 This machine is used in the hydraulic aspects of advanced Modular Valves, can change the pressure of the hydraulic system to reach the workpiece need the pressure 
 This machine is in the electrical, pc programming control, various processing procedures can be arbitrarily changed. 
 The machine according to the different size and shape of the workpiece can be replaced to step up and flange mold

 Flanging quality of the final process is the flanging process, which is the most important one of the processes. At present, the domestic steel drums of the cooperage industry manufacturing production line, the flanging process roughly two processes: a rolling flange; a mold flange. Despite the difference in the two flange method, but the result is basically the same. Belong to the flange parts of the material, thinning of the tensile deformation, other reasons to remove the above analysis, the main impact on the quality of the flanging process technology. From the actual production point of view to analyze the flange cracking and flanging, angle, arc degree, flanging speed.
