Description

A kind of tank body expansion hemmer

Technical field

The utility model belongs to metal can manufacture technology field more particularly to a kind of tank body expansion hemmer.

Background technology

Traditional metal can, is generally process by aluminium or tinplate, the tank body of aluminum metal can generally by punching press gradually It stretches, punch forming technology is more demanding, and the tank body of tinplate metal can is crimped simultaneously by the tinplate blank of plate It is welded into a unshaped tubbiness tank body, is then shaped to tank body using bulging and flange, is welded again after setting, for Setting process, if carrying out by hand, efficiency and cost are higher, and in order to solve this problem, inventor devises a kind of tank processed and sets Flange body in standby, is not only simple in structure, is easy for installation, also can save energy, reducing cost, such as application No. is 200920156763.X Chinese patents, the flange body include a chassis, are equipped with outside flange internal model and flange on the chassis Mould, wherein：The flange internal model is formed by die combination in 4 sons, and it is centrally formed a truncated cone-shaped through-hole；The flange external mold It is formed by die combination outside 4 sons, and its periphery is in truncated cone-shaped, and drive disk, and the driving are equipped on the outside of the flange external mold Disk inner surface is in the truncated cone-shaped that matches with flange external mold periphery, drive part, and a kind of structure is that the flange internal model passes through Center cylinder drives, and the flange external mold is driven by four corners cylinder, and another structure is, outside the flange internal model and flange Mould is driven by same servo motor.Though the flange body can carry out blank flange, internal model is specified by module in 4 sons At flange external mold is specified to be made of 4 sub- external molds, and flange precision is relatively low, can only be tentatively fixed to requiring relatively low tank body to carry out Shape, drive disk inner surface are the truncated cone-shaped to match with flange external mold periphery, in Bulging Process, drive disk and flange external mold with Blank is contacted with line, and contact area is smaller, is easily damaged blank, output defective products, if internal model is driven by center cylinder, because The driving force of cylinder is limited, and flange internal model will be unable to the material slightly thick to material and carry out swollen flange, flange internal model and flange external mold When being driven by same servo motor, after the completion of flange action can not automatic pause, the time that causes to reload is shorter, and directly use is more Danger, while inner membrance can not separate operation with outer membrane, limitation is larger.

Therefore, inventor is dedicated to designing a kind of new tank body expansion hemmer to solve the above problems.
