Description
Technical Field
The patent of the utility model belongs to the technical field of the mould of bending, concretely relates to sheet metal panel beating mould of bending.
Background
The metal plate bending is a processing process of changing a planar plate into a three-dimensional product by passing a metal plate through a pressure device and a die. With the development of times, the shapes of sheet metal products are more various, and new requirements are provided for sheet metal equipment and dies. The existing arc mould can only fold a half arc, and the arc and the plane of the plate have no fillet transition, so that the boundary of the arc and the plane is easy to have crack defects.
SUMMERY OF THE UTILITY MODEL
The utility model provides a to foretell problem, a sheet metal panel beating mould of bending is provided.
In order to achieve the above object, the utility model discloses a technical scheme be: the stamping die comprises an upper die and a lower die, wherein an arc-shaped stamping head is arranged at the lower end of the upper die, and a material pressing plate is fixedly connected above the stamping head; the lower die comprises a base, an arc groove is formed in the upper surface of the base and can be matched with the punching head, and the central angle corresponding to the arc groove is smaller than 180 degrees.
Preferably, the upper part of the pressure plate is fixedly connected with a fixing plate, and the fixing plate is provided with a fixing hole.
Preferably, transition fillets are arranged at the junctions of the two ends of the arc groove and the upper surface of the base.
Preferably, transition arcs matched with the transition fillets are arranged at junctions of two ends of the stamping head and the lower surface of the pressure plate.
Compared with the prior art, the sheet metal bending die (1) can process an arc with the circle center angle smaller than 180 degrees; (2) the circular arc and the plane part of the plate are provided with transition fillets, so that stress concentration in the processing and using processes is avoided.
