Multifunctional perforating machine set

Abstract

The invention belongs to a seamless steel pipe hot rolling apparatus and solves the technical problems of the prior seamless steel pipe production that the punching process, the secondary punching process and the reeling process need respective production apparatus so that the investment is large. The seamless steel pipe hot rolling apparatus comprises a front stage, a main frame, a first section of a back stage and a second section of the back stage, wherein main transmission is connected with a roller in the main frame through a universal coupling, a big end wedged cushion block is movably arranged between the outer side end of a big end rolling shaft block of the roller and an L-shaped roll-box so as to realize the adjustment of the rolling angle of the roller, a worm speed reducer, a commutator and a driving motor connected in sequence are arranged at the left side of the main frame stander of the main frame, the driving motor pushes the roll-box to move through the worm speed reducer and a guide screw to realize the slight adjustment of the rolling angle a, and a big end lower wedged cushion block and a small end lower wedged cushion block are arranged between the lower ends of the big end roller shaft block and the small end roller shaft block of the roller and the L-shaped roll-box to realize the adjustment of a feeding angle of the roller. The seamless steel pipe hot rolling apparatus realizes that one apparatus is multifunctional.

Description

technical field

[0001] The invention belongs to seamless steel pipe production equipment, is suitable for the field of hot-rolled seamless steel pipes, and is mainly used in seamless steel pipes for high-pressure boilers and power stations, high-pressure seamless steel pipes for fertilizer equipment, seamless steel pipes for gas cylinders and accumulators, and line pipes , the production of seamless steel pipes for mechanical structures, oil casing pipes and coal seam pipes, etc. Background technique

[0002] At present, when rolling seamless steel pipes, the solid steel pipes are pierced by a piercer to obtain hollow capillary tubes, and the hollow capillary pipes need to be perforated twice on a secondary piercer to obtain hollow tubes, and the hollow tubes need to be homogenized on a leveling machine. . Seamless steel pipe production enterprises need to be equipped with piercing machines, secondary piercing units and leveling units to complete the above processes. For en...
