Description
Technical Field
The invention relates to the technical field of automobile part manufacturing dies, in particular to a novel blanking die waste material cutting knife structure.
Background
In the manufacturing process of the automobile parts, a plurality of moulds are required, and a blanking mould is one of the moulds. The blanking die is a die for cutting and separating a plate along a closed contour line by utilizing the stamping of an upper die and a lower die, taking the material within the contour line as a blanking part, and in the blanking process, the material outside the contour line belongs to an invalid plate, i.e., scrap, which needs to be removed from the mold, and with the increasing size of automobile parts and the demand for production efficiency, scrap cutting knives are generally required to divide the scrap into two or more pieces and the mold is required to be completed in one step, or the mold length is increased, further increasing the mold cost and machine size requirements, but when completed in one step, there is usually secondary shearing at the intersection of the cutting of the blanking member and the scrap, thereby generating scrap iron, the scrap iron is brought into the die to cause crush damage to the working surface of the die and also cause surface protrusion defects of the stamping part, so that the workpiece needs to be repaired, the production efficiency is influenced and the production cost is increased.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a novel blanking die waste cutting knife structure which can avoid scrap iron, reduce die repairing frequency, improve production efficiency and improve the product quality of blanking pieces.
The technical scheme adopted by the invention is as follows: the novel blanking die waste cutting knife structure comprises a waste upper die knife block, a waste lower die knife block and a blanking knife block, wherein the waste upper die knife block is arranged above the waste lower die knife block, a length-direction knife edge and a width-direction knife edge are arranged on the waste upper die knife block, and the length-direction knife edge is matched with the knife edge of the waste lower die knife block; the side of blanking sword piece under the waste material is located to the blanking sword piece, the width direction cutting edge on the cutting edge of blanking sword piece and the waste material mould cutting edge matches, the length direction cutting edge of cutting edge and the crossing of width direction cutting edge on the waste material mould cutting edge are provided with the downward bellied sharp toper cutting edge, are equipped with the descending space of sharp toper cutting edge under the waste material between cutting edge and the blanking sword piece.
The hardness of the sharp conical blade is greater than 55 HRC.
After the structure is adopted, the sharp-cone-shaped cutting edge is arranged on the waste material die block, so that the waste material at the intersection is broken by the sharp-cone-shaped cutting edge during punching, secondary cutting is avoided, scrap iron is effectively prevented from being generated, and the product quality and the working efficiency are improved.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
FIG. 2 is a schematic view of a scrap cope diecutter block of the present invention.
In the figure, 1, a waste upper die cutter block, 2, a waste lower die cutter block, 3, a blanking cutter block, 4 and a pointed conical cutting edge.
Detailed Description
The invention is described in detail below with reference to the figures and examples.
As shown in fig. 1 and 2, the novel blanking die waste cutting knife structure of the invention comprises a waste upper die knife block 1, a waste lower die knife block 2 and a blanking knife block 3, wherein the waste upper die knife block 1 is arranged above the waste lower die knife block 2, the waste upper die knife block 1 is provided with a length-direction knife edge and a width-direction knife edge, and the length-direction knife edge is matched with the knife edge of the waste lower die knife block 2; the side of waste material lower mould sword piece 2 is located to blanking sword piece 3, and the width direction cutting edge on blanking sword piece 3 and the waste material mould sword piece 1 matches, and the length direction cutting edge of mould sword piece 1 on the waste material is provided with downwards bellied sharp toper cutting edge 4 with the intersection of width direction cutting edge, is equipped with the descending space of sharp toper cutting edge 4 between waste material lower mould sword piece 2 and the blanking sword piece 3.
When the waste material blanking device is implemented specifically, the waste material upper die cutter block 1 is fixed on an upper die, the waste material lower die cutter block 2 and the blanking cutter block 3 are fixed on a lower die, the length-direction cutting edge on the waste material upper die cutter block 1 and the cutting edge of the waste material lower die cutter block 2 are staggered at a certain interval, the waste material is cut off by forming shearing force through up-and-down movement, the waste material upper die cutter block 1 and the waste material lower die cutter block 2 are transversely arranged, the blanking cutter block 3 is longitudinally arranged, and the interval is formed between the waste material lower die cutter block 1 and the blanking cutter block 3, so that the pointed conical cutting edge 4 does not touch the waste material.
When the method is specifically implemented, the pointed conical cutting edge 4 is subjected to surfacing welding by using a welding rod, the welding rod is made of Japanese east China sea TM-11Cr, the current is 75-90mA, and the hardness after surfacing welding is more than 55 HRC. The sections of the sharp conical blade in the length direction and the width direction of the scrap upper die cutter block 1 are triangular.
The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should be covered by the present patent.
