Production technology of aluminum-magnesium alloy fuel tank, automatic hydraulic fuel tank processing equipment 


 Present invention relates to a vehicle fuel tank structure, including the tank body, the lower part of the tank body connection as described in the filling pipe, connected to the other end of said filling pipe and fuel filler through connectivity with the atmosphere, the upper part of said tank body has snorkel. Since the present invention the upper part of the tank body has a snorkel connected with the atmosphere, and preferably, snorkel mounted directly on the highest point of the upper tank, and there is no middle of the curved portion. Therefore, it can prevent the traditional snorkel down the curved part of the accumulation of fuel early to jump the gun and the tank can not breathe. At the same time, the utility model of the fuel limiting valve, whether open or closed state, can effectively prevent the leakage of liquid fuel. 

 Automotive muffler, fuel tank processing equipment - flanging machine 
 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
