Abstract
The utility model provides a horizontal coiler coil core collapsible mechanism which comprises a core shaft body, sector plates, pull bars, liner plates, and wearing layers; a rectangular pyramid core shaft is disposed in the middle of the core shaft body; slideways are disposed on the core shaft body; the lower part of each sector plate is disposed in the slideway and is engaged to the slideway; one end of each pull bar is connected with the core shaft body, and the other end is connected with the bottom surface of each sector plate; the mechanism is characterized in that the liner plates are fixed at two sides of the lower parts of the sector plates; the wearing layers are fixed on the surfaces of the liner plates; the liner plates are made of steel; the wearing layers are made of brass and has a thickness of 2 mm-5 mm. The utility model is simple in structure, and low in dismounting maintenance labor intensity, can effectively reduce the failure rate, and prolong the service life of the core shaft body slideway.
Description
Technical field
The utility model belongs to the rolling machinery technical field, relates in particular to a kind of volume core expansion mechanism.
Background technology
Horizontal reel is the key equipment of hot rolling medium-width strip production line, and this kind coiling machine small investment, floor space is little, technique is simple, is widely used equipment in present domestic hot-rolled steel manufacturing enterprise.Existing horizontal reel all has effect bent with coil of strip and that unload volume, and this effect generally realizes by the volume cored structure.The volume cored structure comprises volume core expansion mechanism, supporting mechanism and transmission mechanism, wherein roll up the core expansion mechanism and comprise fanning strip, liner plate and mandrel body, the fanning strip lower end is arranged in the slideway of mandrel body, liner plate is fixed on mandrel body slideway sidewall, the effect of mandrel body is to provide support framework and provide guide slide for the fanning strip opening and closing for the volume core, because the inboard slideway of mandrel body is narrow, be difficult to processing fixedly liner plate is installed, and in production process, in a single day cooling water enters slideway and can cause the fixedly screw corrosion of liner plate, makes troubles to actual production.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of horizontal reel volume core expansion mechanism, comprise mandrel body, fanning strip, pull bar, liner plate, wearing layer, is provided with the rectangular pyramid mandrel in the middle of described mandrel body, and offers slideway on the mandrel body, described fanning strip bottom is arranged in slideway, described pull bar one end is connected with the mandrel body, the other end is connected with the fanning strip bottom surface, it is characterized in that described liner plate is fixed on both sides, fanning strip bottom, and described wearing layer is fixed on the liner plate surface.
The material of described liner plate is steel.
The material of described wearing layer is brass, and its thickness is 2 ㎜-5 ㎜.
The beneficial effects of the utility model are: liner plate is welded on fanning strip by being arranged on to change on the mandrel body, avoided on the one hand the inconvenience at mandrel body installed inside liner plate, on the other hand when heap copper is repaired liner plate, directly machined again, reduced maintenance cost, and the user can repair does not voluntarily need to return manufacturing firm, therefore shortened maintenance time, improved operating efficiency, owing to having saved screw used when liner plate is installed, avoided causing the fixedly phenomenon of the screw generation corrosion of liner plate because cooling water enters slideway in the production process in addition.The utility model is simple in structure, and dismounting safeguards that labour intensity is low, effectively reduces fault rate, has extended simultaneously the service life of mandrel body slideway.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further explained explanation, in Fig. 1: 1-mandrel body, 2-slideway, 3-fanning strip, 4-rectangular pyramid mandrel, 5-liner plate, 6-wearing layer, 7-pull bar.
Be provided with rectangular pyramid mandrel 4 in the middle of mandrel body 1, and offer slideway 2 on mandrel body 1, fanning strip 3 bottoms are arranged in slideway 2 and match with slideway 2, pull bar 7 one ends are connected with mandrel body 1, and the other end is connected with fanning strip 3 bottom surfaces, and liner plate 5 is fixed on fanning strip 3 both sides, bottom, wearing layer 6 is fixed on liner plate 5 surfaces, the material of liner plate 5 is steel, and the material of wearing layer 6 is brass, and its thickness is 3 ㎜.
During strip coiling, drive pull bar 7 motions by the air compressor that arranges in coiling machine, pull bar 7 drives fanning strip 3 opening and closing that are attached thereto, strip coiling is on the core winding machine structure, when the band steel unloaded volume, air compressor drove pull bar 7 motions, makes fanning strip 3 closures, this moment, core winding machine structure diameter diminished, and can easily realize being with steel to unload volume.
Above the specific embodiment of the present utility model is had been described in detail, but described content is only better embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
