Embodiment
[0038] A kind of progressive die used for forming the reinforced iron of the lower beam, refer to figure 2 , which includes an upper template 2 and a lower template 5; the lower surface of the upper template 2 is provided with a punching punch 21, and the lower template 5 is provided with a waste die 51; Insert, stamp out screw hole 12 at rough blank 8, the waste material of punching out falls through waste material die 51.
[0039] refer to figure 2 with image 3 , the upper surface of the lower template 5 is provided with a sliding groove 52, and the sliding groove 52 is located on one side of the scrap die 51 along the length direction of the lower template 5; ; When the dent punch 6 moves upwards, it is against the lower surface of the blank 8 to emboss the bending dent 11 on the lower surface of the blank 8 .
[0040] refer to figure 2 with image 3 , the lower template 5 is provided with a mounting hole 53, the mounting hole 53 communicates with the sliding groov...

The invention discloses a concatenation mold used for molding an underbeam reinforcing part. According to the technical scheme, the concatenation mold is characterized in that when blank materials are fed on the upper surface of a lower template, initially screw holes are punched in punching concave dies by punching bulge dies; then the blank materials are pushed, so that the punched parts of the blank materials are located in a dent bulge die; in the process that the lower template moves downward, a pressing rod abuts on a fixing plate, so that an abutting part rotates in the direction of the dent bulge die, the abutting part abuts on the lower side wall of the dent bulge die, the dent bulge die abuts on the lower surface of the blank materials, thus a bent dent is stamped out at a premolding underbeam reinforcing part, as it is unnecessary to take out the punched blank materials and turnover the blank materials, the time of molding the underbeam reinforcing part is greatly shortened, and the efficiency of underbeam reinforcing part production is improved.
Description
technical field [0001] The present invention relates to a cold stamping die, more specifically, it relates to a progressive die for molding lower beam reinforcing iron. Background technique [0002] The reinforcing iron of the lower beam is generally a sheet metal part at a 90-degree angle; it is used to fix adjacent objects and play the role of connection and fixation. It is widely used because of its ability to quickly connect adjacent objects. [0003] In the prior art, the state before the bending of the reinforcing iron of the lower beam is as follows figure 1 As shown, the middle part of the lower beam reinforcing iron 1 is processed with a bending dent 11 by stamping, so that the lower beam reinforcing iron 1 can be bent more smoothly; the lower beam reinforcing iron 1 is located on both sides of the bending dent 11. Screw holes 12 are punched out for the screws to pass through. When punching the screw holes 12, the burrs 13 will be generated in the direction of th...
