Description
Technical field
The present invention relates to Bending Mould technical field, specially a kind of refrigerator door fillet bend forming die.
Background technology
The material that refrigerator door uses at present is VCM plates, stainless steel and PCM plate.Each size of surface quality of refrigerator door
The requirement of precision is all higher, and surface must not have macroscopic collide with to scratch trace.
There are two types of the processes of conventional refrigerator door folding fillet, and one is by the way of punching press, allow refrigerator door direct
Bending, bending part formed fillet, but in fact, bending part formed be right angle, the phenomenon that bending part wrinkles, fillet
Smaller, wrinkling is more apparent, influences the surface quality of refrigerator door.Another kind is using first folding fillet again by the way of flange,
This mode in such a way that 45 degree push away, but the phenomenon that be susceptible to scratch, not only influences refrigerator door when flange
Surface quality, and abrasion gets rusty easily.
Both the above mode cannot all meet the bending demand of refrigerator door, the especially bending of small round corner, lead to refrigerator
The surface quality of door shell cannot be met the requirements.
It is found in retrieval, application No. is 201520095310.6 patent, discloses a kind of metal plate and turn over roll-type bender
Structure under the action of cylindricality push type broach and roller and power, realizes the bending of sheet metal component using the molding mode of rolling-type, but
It is the bending that this art solutions is suitable for Rouno Cormer Pregrinding Wheel, does not have applicability to the bending of small round corner.
