The utility model discloses an anchor bolt packaging accessory cold punching device for a wind turbine generator foundation, which comprises a punching machine, a punching upper punch is mounted on an upper slider and a lower slider of the punching machine, a special die is mounted on a workbench of the punching machine and positioned below the punching upper punch, and a vertical die through hole is formed in the center of the special die. The die through hole is matched with a punch of the punching upper punch, a groove-shaped notch is transversely formed in the side face of the special die, and raw material channel steel or raw material flat iron can smoothly pass through the groove-shaped notch. The special die is simple in structure and low in manufacturing cost, punching efficiency is more than five times higher than drilling efficiency, the special die is suitable for cold punching procedures of raw material channel steel and raw material flat iron forming anchor bolt packaging accessories for wind turbine generator foundations, machining quality and precision are guaranteed, production efficiency is improved by times, machining safety is guaranteed, and production cost is reduced. And the anchor bolt for the wind turbine generator foundation is convenient and firm to package.

The invention belongs to the field of motor protection, and discloses a stator core processing protection device with a winding, which comprises a protection main body embedded in an end cover, the protection main body is of a spliced structure, an accommodating cavity is formed in the center of the protection main body, and a sealing cover plate is mounted in the accommodating cavity; a sealing drainage structure is arranged at the bottom of the protection body and comprises an adapter and a drainage tube, one end of the adapter is connected with the bottom of the containing cavity, and the other end of the adapter is connected with the drainage tube; and the drainage pipe extends between the end cover and the bearing chamber at the lower end so as to guide the cooling liquid out of the product. Through the structural design of the protection body, the magnetic attraction installation accessory, the sealing drainage structure and the like, scrap iron, grinding dust and cooling liquid can be effectively prevented from entering the winding in the stator iron core machining process, and the machining quality and later operation safety are ensured. Meanwhile, the device has the advantages of being convenient to mount and dismount, and the tool utilization rate and the production efficiency can be remarkably improved.

The utility model relates to a kind of steel pipe packing flat iron derusting device, belong to steel pipe bundling flat iron rust removal technical field. Mainly including workbench, feed device, polishing device, the workbench is vertically provided with the through slot for limiting the transport of flat iron, corresponding workbench is installed in the both ends of through slot with the feed device of clamping flat iron, polishing frame mouth is set up in the both sides of upper and lower of through slot middle section, polishing device is installed in the both sides of upper and lower of workbench with the polishing of flat iron through polishing frame mouth;Flat iron is inserted into through slot by artificial, then flat iron is clamped by feed device, the both sides of flat iron are polished and rusted by polishing device in the both sides of upper and lower of workbench in turn, limit flat iron by through slot, guarantee the stability of flat iron in polishing process, avoid flat iron to pop out, guarantee processing safety;Uniform speed is fed by feed device, guarantee the uniformity of polishing, guarantee polishing, rust removal quality, can effectively reduce labor intensity, save artificial cost, improve work efficiency.
