Abstract
Bolts for a small baffle of a fixing rolling-mill housing comprise a threaded rod with nuts arranged thereon, and are characterized in that one section of the threaded rod is thinner, and the other section is thicker, the thicker section is provided with nuts, a through groove is formed on the thinner section, and a baffle is fixed on the through groove. The thinner end extends into and penetrates a wire carrying hole of the rolling-mill housing, and is exposed out of a key slot, a key plate is inserted into the key slot and fixed together with bolts, and the thicker end compresses the small baffle through the clamp nuts. Compared with the conventional bolts, the service life of the small baffle bolt is prolonged by two times, and the looseness and fracture during 6 month test are avoided, thereby greatly relieving the work intensity for maintenance staffs.
Description
Technical field:
The utility model is specifically related to the fixedly bolt of rolling-mill housing small front apron.
Background technique
The clamping bolt of rolling-mill housing small front apron is arranged on rolling-mill housing and carries in the hole, and the other end compresses small front apron by nut, and small front apron is fixed roll device then.In production practices, frame is carried a hole serious wear, and the small front apron screw often gets loose or phenomenon of rupture in rolling process, cause small front apron loosening, it is moving that string appears in roll, quality of product caused have a strong impact on, and the safe operation of equipment is also formed very big hidden danger.
Summary of the invention
The utility model aims to provide to be avoided getting loose or the bolt of the fixedly rolling-mill housing small front apron of phenomenon of rupture.
The utility model comprises threaded stem, and threaded stem is provided with nut, it is characterized in that a section of threaded stem is thinner, and another section is thicker, and thicker one section is provided with nut, and thinner one section is provided with keyway, is fixed with the key plate on the keyway.
A thinner end of the present utility model is extend into rolling-mill housing carry a hole and pass and carry a silk hole and expose keyway, insert the key plate in the keyway, and with key plate and bolt together, a thicker end compresses small front apron by tightening nut.
Adopt fixedly rolling-mill housing small front apron of the utility model,, test and loosening and phenomenon of rupture did not take place in 6 months, alleviated attendant's labor intensity greatly than improving 2 times working life with existing bolt.
