Abstract

The invention relates to a roller support reciprocated driving device for a high-speed cold pilger mill, and belongs to the technical field of steel tube rolling machines. The roller support reciprocated driving device comprises a rack, a pair of large gears, a large gear driving mechanism and a pair of connecting rod mechanisms; the pair of large gears are supported to the right end of the rack through large gear axle shafts in the mutually-corresponding manner; the large gear driving mechanism is arranged at the position, corresponding to the right sides of the pair of large gears, on the rack and is in transmission fit with the pair of large gears; and the pair of connecting rod mechanisms are connected with the large gear axle shafts of the pair of large gears and are connected with a roller support movably arranged at the upper portion of the left end of the rack. The roller support reciprocated driving device is characterized in that each of the pair of connecting rod mechanism comprises a connecting rod and a balance hammer, each balance hammer and the corresponding large gear axle shaft are fixed, the left end of each connecting rod is connected with the roller support, and the right end of each connecting rod is connected with the corresponding balance hammer. The motion speed of the pair of connecting rods can be increased, and the steel tube rolling capacity within unit time can be better improved remarkably.

Description

technical field

[0001] The invention belongs to the technical field of steel pipe rolling machinery, and in particular relates to a reciprocating driving device of a roll stand of a high-speed cold-rolling pipe mill. Background technique

[0002] Cold rolling mill is a special equipment for cold rolling by using perforated tubes (also known as capillary tubes or blank tubes), because of its excellent blanking performance and the ability to roll non-ferrous metal seamless tubes with good viscosity, The high material utilization rate and the surface roughness are significantly better than those of cold drawn pipes, so they are widely used in the steel pipe manufacturing industry.

[0003] As known in the industry, a complete set of pipe rolling mills usually includes a conveying device, a feeding device (such as patents CN102059261B, CN10343300B), a steel pipe rotating device (such as CN103433305B, CN104107835A), a rolling device and an output device. The rolling device mainl...
