4results about How to "Meet roughness requirements" patented technology

The application relates to the technical field of insulator manufacturing, and discloses a roughing device for an electric porcelain insulator blank, which comprises a rack, a mold is rotationally connected to the upper surface of the rack, and a lifting frame is slidably connected to the outer surface of the rack; an adjusting shaft is rotationally connected to the outer surface of the lifting frame, a first roughing cutter and a second roughing cutter are fixedly connected to one end of the adjusting shaft, and a first adjusting assembly is arranged at the other end of the adjusting shaft and used for controlling the rotating angle of the adjusting shaft. The roughing device for the electric porcelain insulator blank can effectively solve the problem that, when the cutting amount of the blank is large, the cutting resistance of the roughing cutter is large, the roughing cutter vibrates, scratches, unevenness, burrs and other defects appear on the surface of the blank, the surface flatness is reduced, the size precision of the electric insulator blank is reduced, and the electrical performance and appearance of the insulator are affected.

This utility model relates to a high-precision stainless steel stretching forming mold, belonging to the field of stretching mold technology. The initial stretching mold realizes the blanking and stretching, and then the cleaning component cleans the initial part. After cleaning, the heat treatment component performs heat treatment to reduce the hardness of the initial part and eliminate internal stress. Then, the initial part is stretched and thinned a second time through the secondary stretching mold to form the intermediate part. Then, the 45-degree flanging mold and the 90-degree flanging mold are used to shape the angle of the intermediate part. Finally, the edge trimming mold removes the excess edges and corners of the intermediate part to form the finished part. This production process can reduce the cold work hardening of stainless steel and prevent surface scratches and cracks. After stretching and forming, the product can meet the requirements for surface roughness and flatness of the parts.

This invention discloses a method for machining deep and narrow grooves on an aluminum-magnesium casing. First, a pre-drilling process is performed within the waist-shaped groove using a drill bit of the same width as the groove. This removes most of the excess material, significantly reducing the subsequent milling allowance, improving machining efficiency, and facilitating chip removal during milling. This avoids chip breakage due to poor chip removal and dimensional deviations caused by tool sticking. Then, a variable-speed, half-circle, stepped layer milling method is used to machine to the designed dimensions. High feed rates are used on straight sections to greatly improve machining efficiency, while low feed rates are used on smooth transition sections to prevent tool breakage. The subsequent milling operation incorporates a small portion of the allowance from the previous milling of the sidewall, effectively finishing the first layer of sidewalls while significantly reducing the number of layer milling marks. Compared to existing layer milling methods, this method ensures the groove width, meets the groove wall roughness requirements, and greatly improves machining efficiency.

The utility model relates to foundry goods processing field, concretely discloses a kind of upper cover foundry goods processing device, comprising: rotary disc;Adjusting seat, number is two, be set on rotary disc, two adjusting seats are set to each other close or far away;Two polishing mechanisms, respectively set on two adjusting seats, the polishing mechanism includes two first polishing head, symmetrically installed on the adjusting seat.In the utility model, by rotating the rotating wheel and driving the first screw rod to rotate, the two adjusting seats can be moved synchronously in the adjusting groove, achieving the quick positioning of the upper cover foundry goods of different diameter filters;At the same time, rotating knob drives the second screw rod, the spacing of the two first polishing heads can be finely adjusted, the width change of the sealing groove is adapted, and the versatility and production efficiency of the equipment are improved.
