This utility model discloses a double-bladed stamping die in the field of stamping die technology, comprising: an upper die assembly and a lower die assembly arranged vertically. Both the lower part of the upper die assembly and the upper part of the lower die assembly are detachably equipped with cutting strips. Two cutting strips are designated as an upper cutter and a lower cutter, each with a left-right extending blade. The upper and lower cutters are positioned front-to-back in the vertical direction, with their blades aligned vertically. In this double-bladed stamping die, the upper and lower cutters interlock, shearing and punching the material between the upper and lower die assemblies using their blades. This double-bladed shearing and punching method reduces the punching force requirement, prevents excessive blade wear, and improves the cross-sectional quality of the sheared material. Both the upper and lower cutters are detachable, allowing for timely removal and replacement after blade damage, facilitating maintenance and reducing maintenance costs.

This invention discloses a control method for an eight-cavity precision stamping die system for sub-beam gaskets. The system includes an upper die assembly for transmitting blank holder force during product strip processing, and a lower die assembly below the upper die assembly for transmitting counter-pressure during product strip processing. A cavity for inputting the product strip to be processed is provided between the upper and lower die assemblies. The upper die assembly includes a punch assembly for transmitting blank holder force to the product strip, and the lower die assembly includes a punch assembly for transmitting counter-pressure to the product strip. The upper die assembly also includes a waste discharge assembly for discharging waste generated during product strip processing. This invention overcomes the problem of low production quality in gasket-type products produced by traditional die processing equipment in the prior art. This invention has the advantage of producing high-quality gaskets.

This invention relates to the field of metal processing, and more particularly to an automated metal cutting device for power engineering. It includes a frame, a base plate, a support shell, a self-clamping positioning mechanism, and a cutting mechanism. Both the self-clamping positioning mechanism and the cutting mechanism are housed within the support shell. The self-clamping positioning mechanism includes a self-positioning component for positioning and fixing the metal workpiece. The self-positioning component includes evenly distributed positioning flaps and several elastic positioning blocks. The lower support positioning mechanism includes a support component for supporting and positioning the lower side of the metal workpiece. The support component includes a support frame and a support motor. This invention, through the cooperation of the self-clamping positioning mechanism and the lower support positioning mechanism, achieves simultaneous completion of workpiece positioning and clamping actions. Combined with the positioning flaps and elastic positioning blocks, it significantly improves workpiece clamping efficiency and positioning stability, ensuring that the workpiece does not shift or shake during cutting, effectively improving cutting perpendicularity and cross-sectional quality.

The invention discloses an integrated precise blanking die with a burr removing function and a blanking method, and belongs to the field of metal plate stamping machining. An upper die assembly of the die is provided with a finishing female die and an ejection device, and a lower die assembly is provided with a main male die. A first cutting edge, a conical transition face, a second cutting edge and a step structure are integrated in a cavity of the finishing female die. During blanking, the finishing female die moves downwards to finish blanking through the first cutting edge and the main male die, and burrs are preformed synchronously through the conical transition face; and when the finishing female die returns, the material ejecting device pushes the blanking piece to move downwards, burrs are cut and removed through the second cutting edge, and chippings are collected by the step structure. Blanking and deburring are integrally completed in one punching stroke, the efficiency and the product quality are remarkably improved, and the cost is reduced.
