Abstract
The utility model relates to a T-head multilayer bolt. The T-head multilayer bolt comprises a T-head multilayer bolt body, a screw rod arranged on the T-head multilayer bolt body, a stepped rod arranged on the T-head multilayer bolt body and a bolt head arranged on the T-head multilayer bolt body. A protruding edge structure is arranged below the bolt head, the stepped rod is connected with the bolt head, the screw rod is connected with the stepped rod, a concave face is arranged in the position of connection between the bolt head and the stepped rod, and the T-head multilayer bolt body is formed in a cold heading mode at a time on a cold header through a strong beam mold. Accumulation shape pressing, upsetting and station diameter shrinking are performed on the T-head multilayer bolt without stop through the strong beam mold to perform cold heading through the cold header, and the production technology is high in precision and efficiency and low in consumption. The T-head multilayer bolt is simple in structure, convenient to use and install, easy to operate, low in cost, long in service life, wide in application range, safe and reliable.
Description
Technical field
The utility model relates to a kind of T multilayer bolt.
Background technique
At present, along with industrial develop rapidly, in the connection of component of machine, all to use bolt, but existing bolt is all individual layer bolt, and its preparation process is poor, waste material, the precision of bolt with and working life and effect all can not meet people's needs, this all can bring loss to user.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, use, easy for installation, simple to operate, and cost is low, and long service life is applied widely, has T multilayer bolt of safe and reliable effect.
For addressing the above problem, the utility model adopts following technological scheme: a kind of T multilayer bolt, comprise T multilayer bolt body, and be arranged on T the screw rod on multilayer bolt body, and be arranged on T the step bars on multilayer bolt body, and be arranged on T the bolt head on multilayer bolt body, described bolt head below is provided with flanged structure, described step bars is connected with bolt head, and described screw rod is connected with step bars, and described bolt head and step bars joint are provided with a concave surface.
As preferably, described T multilayer bolt body adopts intense beam mould cold-heading molding once on cold header.
The utility model utilizes intense beam mould to make product be able to complete by once on cold header to build up swaging, jumping-up and undergauge station carries out cold-heading molding, is the production technology of a kind of highi degree of accuracy, efficient, low consumption.It is simple in structure, use, easy for installation, simple to operate, and cost is low, and long service life is applied widely, has safe and reliable effect.
