The application provides a cable core coating forming device for cable processing and relates to the technical field of cable core coating. The device comprises a main body, size adjusting assemblies are symmetrically arranged in the mold, a resisting plate is fixed at one end of the size adjusting assembly, a plurality of delivery wheels are symmetrically arranged in the mold, an arc adjusting assembly is arranged in the delivery wheel, a cleaning assembly is arranged in the fixing seat, and a plurality of cleaning wires are fixed at equal angles on one side of the cleaning assembly. The meshing transmission of the bevel gear and the bevel gear ring can realize the synchronous rotation of the two-side lead screws, and then drive the synchronous displacement of the moving column, the fixing frame, the delivery wheel and the resisting plate, so that the reliable straightening of the cable core can be realized, the central clamping of the cable core can be realized, the cable core can always move linearly along the center of the mold, and the technical defects of the eccentric coating layer, the uneven thickness and the like caused by the bending, the deflection and the shaking of the wire core are solved.

The utility model relates to a kind of assembled conductive copper bar structure, specifically a kind of assembled high load flow distribution's conductive copper bar structure, including assembling seat, two sides on the assembling seat are provided with slot, the side of the assembling seat is provided with fixed seat and the holding plate of the side of the fixed seat, copper bar body is provided between the assembling seat and fixed seat, adjusting mechanism and the limiting fastening mechanism for being used to the assembling of copper bar body are provided in the assembling seat, the adjusting mechanism is cooperated with the transmission mechanism of the side of the fixed seat, the utility model is inserted into the cooperation between the assembling seat and fixed seat, realize the way of inserting into to the superposition fixed of multilayer copper bar, need not be on copper bar hole for bolt fixed, effectively simplify installation and dismounting process, avoid the copper bar structure strength weakening and stress concentration problem possibly caused by hole simultaneously, guarantee the structural integrity and mechanical properties of copper bar.

The utility model discloses a kind of efficient brushless hollow cup DC motor stator, including the stator core made of high saturation soft magnetic material, the middle part of the stator core is equipped with core inner hole, the inside of the core inner hole is equipped with cup type winding, and the inside of the core inner hole is attached with insulating film, the cup type winding is by several sheet hexagonal winding column and is rolled by coiling machine, the cup type winding is fixed on the inner wall of core inner hole by high temperature epoxy adhesive layer;The utility model not only guarantees the electrical insulation between stator core and winding cup, but also reduces the inconvenience caused by artificial paste insulating film, improves the quality reliability of stator, shortens manufacturing cycle, improves work efficiency;Relative to filling process, manufacturing cycle is shortened by 2 / 3.

This invention discloses an insulating film for battery top covers, its preparation method, and a battery, relating to the field of battery manufacturing technology. The insulating film for battery top covers comprises an insulating protective layer, a foamed flame-retardant layer, and an insulating adhesive layer stacked sequentially. The foamed flame-retardant layer includes a matrix resin and functional fillers dispersed in the matrix resin, with a mass ratio of matrix resin to functional fillers of 1:(1~1.5). The functional fillers, by weight, include: 45%~70% expandable graphite, 10%~20% ammonium polyphosphate, 5%~10% melamine, 5%~10% pentaerythritol, 1%~10% titanate coupling agent, and 2%~10% fumed silica. This invention addresses the problem in existing technologies where the insulating film's insulation performance deteriorates under high-temperature conditions and it cannot effectively cope with thermal runaway.
