5results about How to "Stable life" patented technology

The application belongs to the technical field of mobile charging equipment and relates to a compact charging vehicle body. The vehicle body comprises a frame body integrally welded and formed, which is internally provided with first-layer, second-layer and third-layer battery placing frame structures stacked in sequence from top to bottom. The bottom center of the third-layer battery placing frame structure is provided with a water-cooled cabinet storage frame structure for installing a water-cooling module to realize efficient heat dissipation. The frame body is provided on one side with an integrated energy conversion module placing frame structure for installing functional units. The bottom of the frame body is provided on both sides with fixing frames, and the frame body is connected with a foot pedal structure through a Z-shaped foot pedal connecting frame. The application solves the problems of large size and inconvenient movement of the existing mobile charging vehicle through a multi-layer stacking layout, modular integration and integrated welding structure, has the advantages of compact structure, light self-weight, good heat dissipation performance, convenient operation and maintenance and the like, and significantly improves the space utilization and environmental adaptability.

The utility model discloses a cross axle frame preforming die, including corresponding preforming upper die and preforming lower die, and is equipped with preforming cavity between preforming upper die bottom surface and preforming lower die top surface, and is equipped with preforming convex column in preforming cavity in preforming lower die, and preforming convex column upper end surface is higher than preforming parting surface, and preforming convex column upper end surface is equipped with a preforming positioning groove, preforming cavity front side middle part and rear side middle part all are equipped with a preforming cylindrical groove. The utility model discloses an arc -shaped groove structure of positioning upsetting blank is designed, and special tongs are used to hold upsetting blank and place to preforming convex column simultaneously, make upsetting blank be positioned in front and back, left and right direction all and be positioned well, ensure that metal material can fill preforming cavity in preforming process, and preforming upper die and preforming lower die stress balance also, alleviate the forging amount of final forging process, and forging quality improves, and preforming die and final forging die are all life stable.

This invention discloses a cutting insert and a drilling tool for detachable mounting on a tool holder. The insert includes a first mounting plane and a second mounting plane, which form the seat surface of the insert; two V-shaped mating surfaces that fit and conform to the V-shaped positioning surface on the tool holder; at least one screw hole; four main cutting edges forming a polygonal outline on the V-shaped mating surfaces; a chip groove adjacent to the main cutting edges; a chisel edge connecting the main cutting edges; and a drill tip formed by the intersection of the theoretical extensions of the cutting edges of the main cutting edges. The insert as a whole has a symmetrical structure relative to the center line connecting the screw holes. The cutting insert can be mounted with either the first or second mounting plane facing the tool holder, allowing for drill tip interchangeability. This invention adopts a double-sided symmetrical design, overturning the traditional drill bit model that can only use one cutting tip, significantly improving the utilization rate of the insert material.

The utility model provides a kind of water-saving garden fountain, belong to fountain equipment technical field, including the circulating water tank that raw water tank outlet end is connected, the backwater cavity bottom of circulating water tank is connected with circulating pipeline, the water outlet end of circulating pipeline is provided with filter box, the side in filter box close to circulating pipeline is provided with hair collection subassembly, multiple filter plates are provided in filter box inner middle part, one filter assembly is provided between two filter plates, the utility model is isolated to the hair in the recycled water by hair collection subassembly and is collected, recycled water is filtered secondly by filter plate, recycled water is filtered thirdly by filter assembly between two filter plates, recycled water is pumped into raw water tank by backwater pump again, recycled water is supplied into water supply cavity by booster pump, recycled water is supplied into fountain again, to improve the filtering effect of recycled water, and then the life of pump group on backwater pipeline is stabilized, and the quality of recycled water outlet is improved, so that the overall life of equipment is improved.

The utility model provides a long -life high -performance screw tip tap has the coarse handle handle, thin neck and screw tip of coaxial connection as an organic whole, the chip flute made of screw tip is three groove structure, and the chip flute of three groove structure is three equal parts distribution relative to tap center axis, and the chip flute groove shape is two straight lines two circular arc form, and the smooth transition between circular arc, the screw tip still is made with straight flute, and the screw tip tap adopts the high -speed steel material of vacuum heat treatment, cryogenic treatment and passivation treatment to make. The utility model solves how to reach the technical problem of high -efficient tapping processing of high -performance screw tip tap product on numerical control equipment, improves tap life, processing high -efficient, quality is stable, long -lived, is fit for promotion.
