The integrated roll forming device for the lithium cobalt oxide positive plate not only can ensure that the pole plate is compactly rolled, but also can reduce the internal roll stress of the pole plate.

The utility model discloses a veneer reeling machine material supporting device which comprises a veneer reeling machine and a material supporting assembly, the material supporting assembly is connected to the veneer reeling machine in a rotating mode, the veneer reeling machine abuts against a plate in a sliding mode through a rolling wheel, the end, stretching out of the veneer reeling machine, of the plate abuts against the material supporting assembly, and a supporting arm frame is connected to the material supporting assembly. The end, away from the material supporting assembly, of the supporting arm frame is perpendicularly connected with a supporting roller assembly, the end, away from the material supporting assembly, of the plate abuts against the supporting roller assembly, the material supporting assembly drives the supporting roller assembly to rotate so that the plate can be rolled into an arc plate, a supporting rod assembly is hinged to the supporting arm frame, and the supporting rod assembly and the supporting roller assembly are symmetrically arranged. The end, away from the supporting arm frame, of the supporting rod assembly abuts against the ground. According to the material supporting device of the plate rolling machine, the material supporting length is increased, supporting adjustment is easy, convenient and rapid, the material supporting device is suitable for rolling of long-specification plate arc plates with various radians, the phenomenon that the arc plates are bent due to the fact that the suspended plate end of the discharging side falls down is avoided, and the rolling quality of the arc plates is guaranteed.

The utility model relates to the technical field of lithium battery processing, and particularly discloses lithium battery processing pole piece rolling equipment which comprises a mounting seat, a roller I, a roller II and a variable component, the distance between the first roller and the second roller is adjusted according to the thickness of the lithium battery, and when the distance is adjusted, the variable assembly is arranged to control the rotating speed of the first roller and the rotating speed of the second roller in real time according to the thickness of the lithium battery. The variable assembly adjusts the rotating speed of the first roller and the second roller in real time according to the thickness of the lithium battery pole piece, and it can be ensured that the pressure borne by the pole piece is more uniform in the rolling process; when a thicker pole piece is rolled, the rotating speed of the roller is reduced, so that non-uniform stress of the pole piece caused by too high rotating speed is avoided; when a thin pole piece is rolled, the rotating speed of the roller is increased, and the production efficiency is improved while the rolling quality is ensured; according to the dynamic adjusting mode, the rolling uniformity of the pole piece is remarkably improved, the defects of thickness deviation, cracks and the like of the pole piece caused by uneven pressure are reduced, and the universality and adaptability of equipment are improved.

The present invention provides a roller assembly and a rolling mill for rolling double-toothed track steel, the roller assembly for rolling double-toothed track steel comprises: an upper roller, a lower roller, a left roller and a right roller, the left roller has a left forming surface, the right roller has a right forming surface, the upper roller has an upper forming surface, the lower roller has a lower forming surface, the left forming surface, the right forming surface and the upper forming surface and the lower forming surface together form a rolling channel; the upper roller and the lower roller can move in the up and down directions respectively; the left roller and the right roller can move in the left and right directions respectively. It can be applied to double-toothed track steels with similar shapes but different sizes, and when the cavity wall of the rolling channel is worn, it can be compensated online without stopping production and disassembling the rollers, thereby ensuring production efficiency and saving the purchase cost of the rollers.

This invention discloses a tooling and manufacturing method for manually producing square steel torsion springs, including a dense coil rolling mold, a hook forming mold, and a starting pitch mold. The dense coil rolling mold includes a rolling mandrel, a limiting plate, and a rolling handle. The hook forming mold includes a forming handle, a rotating shaft, and a forming vertical rod. The starting pitch mold includes a fixing block. This application utilizes the cooperation between the dense coil rolling mold, the hook forming mold, and the starting pitch mold, along with existing lathes and stamping machines, to sequentially complete the three steps of dense coil rolling, hook forming, and starting pitch production. This enables manual production of torsion springs to meet production needs, thereby eliminating the need to purchase a torsion spring machine and reducing enterprise expenses.
