[ detailed description ] embodiments
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses a mould bolt binding suitable for large-scale screw press, as shown in fig. 1, fig. 2, be applicable to 4000T screw press fastening bolt's fastening, current 4000T screw press attaches present instrument is the long handle box spanner of internal diameter 85mm, and fastening bolt's size also is 85mm and the spanner is supporting. The installation space can only accommodate one arm for operation, the space is small, the bolt is large, and the weight of the die is large (270 kg to 430 kg), and the arm is difficult to tighten the fastening bolt.
The utility model discloses the internal diameter of bolt cover 2 of binding also is 85mm, however, because of extension rod 3's effect, operating personnel can externally operate, and operating space is big promptly, can exert oneself jointly by two arms, so can easily tighten fastening bolt.
Specifically, the utility model discloses a bolt cover 2 for chucking fastening bolt, bolt cover 2 are used for the card in fastening bolt's outside. Bolt sleeve 2 includes integrated into one piece's pipe and cyclic annular inside lining 5, the cross section of cyclic annular inside lining 5 is the plum blossom form, chucking fastening bolt that can be convenient, its internal diameter size with be 85mm, highly establish to 20mm, can save material, its thickness is established to 6mm, its outer wall laminating is fixed on the inner wall of pipe, so, the outward appearance of bolt sleeve 2 becomes the pipe form, this pipe external diameter is 100mm, cooperate with cyclic annular inside lining, length is 100mm, and is more pleasing to the eye, and, also, can play the guard action to cyclic annular inside lining 5 through the pipe of outside.
