Technical Field

The invention relates to a tape spraying device. In particular to an intelligent simulation strip spraying device for ultrathin soft magnetic silicon steel sheets.

Background

The production of the ultrathin soft magnetic silicon steel sheet strip is characterized in that an alloy steel ingot with a certain element proportion is melted by a melting furnace such as a medium-frequency induction furnace and the like to prepare a molten alloy, the molten alloy is sprayed to the surface of a copper roller rotating at a high speed at a certain linear speed at a certain temperature under the protection of inert gas at a certain pressure from a nozzle, and the molten alloy is spun by the copper roller to obtain the ultrathin soft magnetic silicon steel sheet strip, and then the alloy thin strip with the thickness is continuously prepared by one-step molding. In the preparation process, the nozzle structure, the pressure, the speed, the clean, smooth and smooth flatness of the working wall surface of the copper roller, the cooling effect and the like have extremely important influence on the belt manufacturing quality. On one hand, the existing tape spraying equipment has certain unreasonable integral structure, so that the preparation operation is inconvenient; particularly, the matching structure and the operation mode of the copper roller and the nozzle are not reasonable.

The copper roller runs at the same position all the time or for a long time to receive the sprayed liquid of the nozzle for rotary throwing, so that on one hand, the copper roller runs locally overheated to be damaged and damage the copper roller, and on the other hand, the copper roller runs locally for too long time to influence the surface smoothness of the copper roller and further influence the quality of a sprayed belt. The surface of the copper roller is easy to damage and short in service life, and the quality of the sprayed belt is affected. The polishing device polishes the same part of the copper roller for a long time, so that traces, grooves and the like are polished on the surface of the copper roller, the surface roughness of the copper roller is deteriorated, and the belt manufacturing quality is seriously influenced.

And the cooling system of its copper roller constitutes complicacy, and the debugging is difficult, and operating stability is not enough, and at the operation in-process, its spring has been avoided not to receive its self unstability and equipment vibration influence and the unstable operating condition appears, and appears the end connection cooperation between its spring and the device that splines and appear stability and reliability scheduling problem equally easily, and the elasticity effort on its spring cross section is uneven moreover for static cover and the unbalance of hollow shaft end face sealing force under the spring force effect. This, on the one hand make the sound adapting unit wearing and tearing of rotary joint aggravate to make its life short, on the other hand, the unbalanced sealing plane frictional force leads to taking place easily and leaks, and again on the one hand to the adaptability of water supply pressure not enough, still on the one hand its elastic component fatigue factor etc. cause the unstability for the operation, and the debugging is difficult.

In yet another aspect, there is a need for further improvements and improvements in the structure and manner of operation of existing polishing apparatus. If there is certain irrationality in its structure of current burnishing device and corresponding operation mode, its cooling copper roller work wall receives influence such as adhesion stereoplasm granule and dirty scaling thing, bits easily, and polishing effect is poor on the one hand, and on the other hand needs frequently to carry out manual cleaning to cooling copper roller surface, causes the working face of copper roller can not satisfy the production technology requirement, seriously influences and spouts the area quality, influences and spouts the normal operating of area equipment, influences and spouts area production efficiency.

The intelligent simulation strip spraying equipment for the ultrathin soft magnetic silicon steel sheet comprises a rack 40, a copper roller 20 arranged on the rack 40, a copper roller polishing device, a copper roller cooling system, a medium-frequency induction heating furnace 27 fixed on the rack, a nozzle 27a of the medium-frequency induction heating furnace and the like. The frame 40 is connected to a cantilever 40a, on which the intermediate frequency induction heating furnace is disposed, through a column at one end thereof. An automatic opening/closing type support device is provided corresponding to the arm 40 a. The automatic separation and combination type supporting device comprises a transverse telescopic driver 29 arranged on a stand column at the other end of the machine frame, a guide sleeve 25 and a conical tip connecting and positioning shaft 25a connected between the telescopic driver and the conical connecting sleeve 24 at the free end of the cantilever through the guide sleeve. When the intermediate frequency induction heating furnace is in load operation, the telescopic driver 29 is controlled by the corresponding controller to enable the conical tip connecting and positioning shaft 25a to extend out to be matched and connected with the corresponding conical connecting sleeve 24 so as to position and strengthen the cantilever.
