Closed trimming die is how to process it?

The closed trimming die comprises a upper mold base and a lower mold seat, characterized in that the lower mold base of the product is further provided with a slidable support base, and the support base of the product is in the working condition and the cavity Forming a closed cutting edge, and the product of the support seat is not working when the top of the plane is higher than the punch groove plane, the cutting surface is gradually lower than the punch groove plane, the product forging precision positioning in the lower mold support , The bearing and the gap sliding with the lower die edge, the forgings in the completion of trimming before the action, the first mold down to move until the compression of the forging and the lower mold support seat to form a closed cavity, then forgings in The closed cavity continues to move downward until the trimming is completed, thus forming the trimming of the forging is carried out in the enclosed space of the precise positioning, which completely avoids the occurrence of the forging deformation and the burr generation.

Closed trimming die, including the upper mold base and the lower mold base, the product on the mold base with a punch, the product of the punch with the shape of the workpiece to match the cavity, the product under the mold base set There is a die with a blade, the product of the die is also equipped with red mouth groove, the product edge is set in the edge of the punching slot, which is characterized by the product under the mold base also has a sliding support , The support of the product in the working condition and the punch inside the cavity to form a closed cutting edge cavity, and the product of the support seat is not working when the top of the plane is higher than the punch groove plane, the plane is gradually low In the punching groove plane, the utility model forgings are precisely positioned in the lower mold support seat, and the bearing seat is slid with the gap of 0.02-0.03 mm in the lower die edge, and the forging is completed before the cutting action Move until the pressing of the forging and the lower die support seat to form a closed cavity, then forging in the closed cavity to continue downward movement, until the trimming work is completed, so that the formation of the forging of the trimming is Precise positioning of the enclosed space carried out, completely avoid the deformation of the forging and burr generation.
