Abstract
Description
Technical Field
[0001] This utility model relates to a stamping blanking die, specifically to a continuous blanking die for left and right parts that reduces the proportion of scrap. Background Technology
[0002] When sheet metal is continuously fed, due to the staggered arrangement of the left and right parts, the first sheet and the scrap material near it are cut first. This causes the scrap material strip in the middle to collide with the scrap cutter on the lower die during the feeding process after the second sheet is cut, due to insufficient support. This makes the sheet metal prone to deformation and may even cause jamming. To avoid this, the connection between parts must be made wider. This not only wastes material but also still results in deformed workpieces after cutting. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a continuous blanking die for left and right parts that reduces the proportion of waste, makes punching smooth and less prone to jamming.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a continuous blanking die for left and right parts with reduced waste ratio, including an upper die base and a lower die base, wherein a pair of feeding guide blocks are provided on the lower die base at the feeding end;
[0005] The lower die base has a first punching die and a second punching die at the first station for punching two sets of through holes on the workpiece; the upper die base has a matching first punch and a matching second punch at the first station; the lower die base has a left blanking cutter block at the second station for blanking the left part of the workpiece; the upper die base has a matching left blanking upper cutter block at the second station; the lower die base has a right blanking cutter block at the fourth station for blanking the right part of the workpiece; the upper die base has a matching right blanking upper cutter block at the fourth station; the lower die base has a cutting die at the fourth station. The upper die base is equipped with a first lower cutter that cuts off the middle section of the scrap material on the outer side of the left workpiece, a second lower cutter that cuts off the connecting part between the right workpiece and the adjacent workpiece, and a third lower cutter that cuts off the scrap material on the outer side of the right workpiece. The upper die base is equipped with a first upper cutter, a second upper cutter, and a third upper cutter that cooperate with each other. The lower die base is equipped with a floating feeding mechanism on the workpiece at the fourth station near the second lower cutter. The floating feeding mechanism includes a floating block that is movably embedded in the right lower cutting block. The lower die base is equipped with a nitrogen spring that pushes against the floating block. The end of the floating block is near the second lower cutter.
[0006] As a preferred embodiment, the lower die base is provided with several guide blocks arranged along the feeding direction.
[0007] As a preferred embodiment, the lower mold base is provided with a plurality of material support rollers arranged along the feeding direction.
[0008] As a preferred embodiment, the lower mold base is provided with two material support blocks at the feeding end, and the feeding side of the material support block is provided with a receiving part with a downwardly inclined surface.
[0009] As a preferred embodiment, the first punching die button and the second punching die button are detachably mounted on the material support block.
[0010] As a preferred embodiment, the lower die holder is provided with a guide roller array below the left and right blanking cutter blocks to discharge the workpiece.
[0011] The beneficial effects of this utility model are:
[0012] This mold has an empty station in the middle, with the right part unloading at the last station. A floating feeding mechanism is located on the lower mold base near the second lower cutter on the fourth workpiece. This mechanism includes a floating block movably embedded in the right unloading lower cutter block. A nitrogen spring in the lower mold base pushes against the floating block. The end of the floating block is near the second lower cutter, thus reducing feeding difficulty. The floating feeding mechanism can better feed the scrap portion after the left part is unloaded, avoiding interference and collision between the scrap and the second lower cutter block, allowing for a smaller scrap width and improved material utilization.
[0013] Because the lower die base is equipped with a guide block that is positioned along the feeding direction, it facilitates the conveying of the material strip.
[0014] The lower die base is equipped with several rows of material-supporting rollers arranged along the feeding direction, which further facilitates the conveying operation of the material strip.
[0015] The lower die base has two material support blocks at the feeding end, and the feeding side of the material support block has a receiving part with a downward inclined surface, which facilitates the feeding operation.
[0016] Because the lower die holder has guide rollers below the left and right blanking blocks to discharge the workpiece, the waste material can be discharged more smoothly. Attached Figure Description
