The utility model discloses a double edge boring cutter, including boring cutter body and two boring cutters, the front of boring cutter body is equipped with the mounting groove, is used to accommodate two boring cutters, and two boring cutters reverse parallel arrangement, the two ends of boring cutter head part are equipped with the export respectively on the mounting groove, and the export width is equal to boring cutter's handle width, and the head of boring cutter is stretched out, makes boring cutter to be able to adjust the position along the mounting groove freely, the waist type hole is equipped with on boring cutter and is close to its head one end, and the mounting groove bottom is equipped with a plurality of with the waist type hole matched mounting screw hole, and boring cutter is fixedly arranged in the mounting groove through fixed bolt. The design optimized boring cutter and boring cutter body's fixed mode and the structure of mounting groove, and boring cutter and boring cutter body adopt the front bolt fixed, cooperate the mounting groove opening design to make boring cutter's stability stronger, can be used for more accurate equipment manufacturing.

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 provides an electrode cap shaping tool assembly, including a shaping gear, connecting bearings respectively fitted at both ends of the shaping gear, a roller assembly, a shaping tool, and a cover body respectively disposed at both ends of the shaping gear and open in the middle. A cutting groove and a triangular roller groove are formed in the middle of the shaping gear. The roller assembly is placed in the roller groove, with both ends of the roller assembly abutting against the cover body, allowing the roller assembly to rotate and compress the deformed electrode cap within the roller groove. The shaping tool is installed in the cutting groove, and when the shaping gear rotates, it drives the shaping tool to cut and shape the excess part of the deformed electrode cap. This invention uses a rolling compression method to first compress the electrode cap back to its original shape with a reduced tip diameter and surface finish, and then uses a double-edged shaping tool to remove the excess part, maximizing the restoration of the electrode cap to its original shape while minimizing over-cutting.

This invention discloses a double-edged tipping paper cutter and its application. The double-edged tipping paper cutter includes a cutter body (1); the two ends of the cutter body (1) are a cutting edge (11) and a back (12), respectively; the cutting edge (11) has a double-edged structure at the same end, including a cutting bevel (111) and two cutting edges (112), the two sides of the cutting bevel (111) are a first cutting edge (113) and a second cutting edge (114), and the angle between the cutting bevel (111) and the thickness direction of the cutter body (1) is 45°. By combining the adjustment of the cutting angle of the tipping paper cutter, this invention adopts a double-edged design on the working surface, reducing and minimizing stress concentration on the cutting edge of the tipping paper cutter without changing its material toughness and maintaining the rigidity of the raw material, thereby effectively extending its service life, ensuring the cutting quality of tipping paper sheets, and reducing the cost increase and waste caused by damage to this accessory.

The present application disclosed an electric knife sharpener for elastically grinding double edges comprises an electric motor, a rotating shaft, a guide cover and a grinding assembly, wherein the rotating shaft is mounted on the electric motor, a driving pin is convexly arranged on the rotating shaft, the grinding assembly comprises two grinding discs, the grinding discs is provided with a sliding shaft sleeve, the sliding shaft sleeve is sleeved on the rotating shaft, and the sliding shaft sleeve is provided with a sliding groove, the driving pin is slidably mounted in the sliding groove; the sliding shaft sleeve is also sleeved with a compression spring; the extending axis of the grinding groove is obliquely arranged with respect to the central axis of the rotating shaft, both cutting edges of the cutter can maintain effective contact with the grinding surface of the grinding disc, eliminating the grinding blind area.
