Abstract
The utility model discloses a rolling mill blank-pulling mechanism, which solves the problem that the blank-pulling stroke of a push head driven by a hydraulic cylinder is limited by the stroke of the hydraulic cylinder and the inlet bench type in the prior art. The rolling mill blank-pulling mechanism comprises a sliding rack (6) arranged on a foreground base (1).One end of the sliding rack (6) is fixedly connected with a push head (7) and the side surface of the other end thereof is horizontally equipped with a front pin (17) and a rear pin (18) at intervals. A front sprocket wheel (2) is arranged on a front bearing seat device (3) and a rear sprocket wheel (20) is arranged on a rear bearing seat device (21). A chain (5) is arranged between the front sprocket wheel (2) and the rear sprocket wheel (20). The front end of the chain (5) is fixedly connected with the front pin (17) and the rear end of the chain (5) is fixedly connected with the rear pin (18) so as to form a closed chain transmission loop. The rolling mill blank-pulling mechanism is simple in structure and convenient in operation, which can meet the requirements of steel pipes of different specifications.
Description
Technical field
The invention belongs to the seamless steel pipe production technical field, be specifically related to a kind of milling train blank pushing machine structure of seamless steel pipe production.
Background technology
At present, more the blank pushing machine structure of producing slitless tube mill both at home and abroad adopts the hydraulic cylinder drive to cut somebody's hair and realizes pushing away solid billet or hollow ingot, this mechanism pushes away the restriction that the base stroke is subjected to hydraulic cylinder travel, portable station pattern, particularly the milling train portable station uses under the situation of plug, needs a large amount of tool and moulds in actual production.And if in design process charge length change too greatly, vary in diameter greatly, also to consider to push away the interference problem of base hydraulic cylinder and graphite lubrication case, restraint device, and may cause the length increase of milling train foreground, the use cost of increase plug.The on-the-spot position difficulty of cutting somebody's hair of adjusting under the situation that particularly big unit production specification is many, batch is few, has strengthened labour intensity especially, and productivity ratio is also very low.
Summary of the invention
The blank pushing machine structure that the invention provides a kind of milling train has solved prior art and has adopted hydraulic cylinder to drive to cut somebody's hair and realize pushing away base and exist and push away the base stroke and be subjected to the restriction of hydraulic cylinder travel, portable station pattern and the use cost height that milling train foreground length increases and core is given, and improves the technical problem of unit productivity ratio.
The present invention overcomes the above problems by following scheme:
A kind of blank pushing machine structure of milling train, comprise the foreground base, the travelling carriage that on the base of foreground, is provided with, one end of travelling carriage is fixed together with cutting somebody's hair, bearing pin and rear pin shaft before on the side of the other end of travelling carriage, being provided with to the horizontal interval, side at the foreground base is respectively arranged with front-end bearing pedestal device and rear bearing block device, the front-end bearing pedestal device is provided with preceding sprocket wheel, the rear bearing block device is provided with the back sprocket wheel, the axle of preceding sprocket wheel is successively by first shaft coupling, reductor, brake, second shaft coupling is mechanically coupled together with the output shaft that is arranged on the motor on the motor bearing, before described, be provided with chain between sprocket wheel and the back sprocket wheel, and the head end of this chain and preceding bearing pin are fixed together, the end and the rear pin shaft of this chain are fixed together, form the chain transmission loop of a sealing, travelling carriage is provided with a row travelling carriage bolting hole of above-below direction, on the caudal peduncle of cutting somebody's hair, also be provided with one of above-below direction and be listed as the bolting hole of cutting somebody's hair, the different travelling carriage bolting holes and the combination back, bolting hole of cutting somebody's hair are fixed with set bolt, thus the adjustment up and down that realization is cut somebody's hair.
Described reductor is provided with the encoder that the position of cutting somebody's hair is detected.
The present invention has simple in structure, easy operating can satisfy the requirement of different size steel pipe, the equipment investment of having saved early stage, and the plug use cost of saving the later stage.The portable station that can satisfy different types uses.
