7results about How to "Reduction procedure" patented technology

The utility model relates to the technical field of workbenches, in particular to a fixed welding workbench with a magnetic adsorption fixing function, which comprises a table top, an electromagnetic plate and a fixing block, the electromagnetic plate is fixedly connected below the table top, a first fixing plate is fixedly connected on one side of the electromagnetic plate far away from the table top, and a second fixing plate is fixedly connected on the other side of the table top. The connecting plate is fixed to the supporting plate through the fixing bolts, a workpiece can be placed on the first fixing plate and the second fixing plate, the fixing blocks are embedded into the corresponding fixing grooves according to the corners of the workpiece, the magnetic blocks in the fixing grooves can tightly attract the fixing blocks, and the four fixing blocks are sequentially placed into the corresponding fixing grooves. By means of the mode that the large-size workpiece is positioned through the multiple fixing blocks, the procedure of fixing the workpiece through an external clamp is reduced, and the machining efficiency of workers is improved.

A battery housing (10) includes an integrally formed plate body (110), the plate body is in a preset shape in an unfolded state, and is provided with multiple preset folding portions, and the plate body is separated to form a cover plate and multiple side plates along the multiple folding portions. The multiple side plates are configured to be folded along the corresponding folding portions and connected to form a middle housing (1101) with closed peripheral sides and open ends, and the cover plate is configured to be folded along the preset folding portion and close the corresponding open end (1102) of the middle housing to form an accommodating space for accommodating an electrochemical unit (20) inside the middle housing.

The utility model relates to the technical field of vehicle parts, in particular to a wire harness fixing device and a vehicle. The wire harness fixing device comprises a clamp body and a flexible compensation structure, and further comprises a [-shaped main body part and mounting lug plates connected with the two ends of the main body part, and each mounting lug plate is provided with an assembly through hole; and the flexible compensation structure has elasticity and is fixedly connected to the inner side of the main body part. The wire harness fixed by the wire harness fixing device can be stably restrained. Through the clamp body, it can be ensured that the flexible compensation structure compresses and fixes the wire harness, the flexible compensation structure keeps gapless with the wire harness, stable constraint is formed, the installation efficiency is high, the wire harnesses of various section specifications can be adaptively arranged in the installation space in a penetrating mode, the universality is high, the occupied space is small, and the attractiveness is high.

The present disclosure provides a lithium iron phosphate, a preparation method thereof, and an application thereof. The preparation method includes: dispersing a lithium source by using an emulsifier, then adding a first initiator, and carrying out a first polymerization reaction to obtain an intermediate product A; adding a mixed solution of methyl methacrylate, a crosslinking agent and a second initiator to the intermediate product A, and carrying out a second polymerization reaction to obtain an intermediate product B; mixing the intermediate product B, an oxidant, an iron source and a phosphorus source, and carrying out a third reaction to obtain an intermediate product C; and dispersing the intermediate product C by using a glucose solution, and carrying out drying and calcining to obtain the lithium iron phosphate. The present disclosure also provides the lithium iron phosphate obtained by the preparation method. The present disclosure further provides a positive electrode material, including the lithium iron phosphate. According to the preparation method, a nano-scale lithium iron phosphate can be directly obtained, and procedures, such as pulverization, and energy consumption in the manufacturing process can be reduced. The lithium iron phosphate has evenly distributed elements, and has good charge and discharge properties when being used as a positive electrode material.
