Abstract
The invention relates to the seamless steel tube piercing push rod, comprising a push rod cart, rotary mechanism and the locking device, featuring in the hollow shaft installed on the push rod cart, front of the hollow shaft connected to the push rod and the rear installed with passive gears. The rotary structure comprises the sliding base and the motor and motor belt driving the rotation of the motor, active gear teething with the passive one, and the slide base controlled by the hydraulic cylinder and sliding up and down along the fixed slide track. It is simple in structure, reliable in drive, and improved in productivity.
Description
Technical field:
The invention belongs to metallurgy industry seamless steel pipe production technical field, be specifically related to a kind of punching machine post rod device of seamless steel pipe.
Background technology:
In the process of producing seamless steel pipe, the steel billet that heats is sent in the punch pass by blank pushing machine, pipe is under the roll effect, advance while rotating along the roll line direction, realized once nipping, when pipe with after the top contacts, pipe still will drive top and push rod to be continued rotation together and advances, and realizes that secondary nips, in the case, for less top and push rod, still can realize above-mentioned action, but for bigger top and push rod, because weight has strengthened, realize relatively difficulty of above-mentioned action, tend to roll the card accident, influence steel rolling production.At this problem, at present, in tube rolling is produced, also taked some measures, drive the push rod rotation as useful friction pulley, its shortcoming is to tend to because of the frictional force deficiency, and can not drive the push rod rotation; Also there is employing that one cover is installed on ejector rob trolley provided and can drives the device of push rod rotation, but so ejector rob trolley provided weight is increased the weight of; Also having some is to adopt wobble gear mechanism, and its shortcoming is often in order to make gears engaged relatively good, need add the gear wheel width.
Summary of the invention:
The object of the invention provides a kind of new pin-lift arrangement, can more effectively overcome the shortcoming that prior art exists.
It is ejector rob trolley provided that the present invention is achieved in that it comprises, rotating mechanism and blocking device, it is characterized in that the hollow shaft that links together with push rod is installed on the ejector rob trolley provided vehicle frame that can walk in orbit by bearing, the hollow shaft front end is connected with push rod, the rear end is equipped with driven gear, rotating mechanism comprises on the sliding seat and motor mounted thereto and the driving gear that can be meshed with driven gear by the motor driven rotary, freewheel clutch is installed in driving gear, sliding seat can be slided up and down on ground way by hydraulic cylinder control, under the promotion of the piston rod of hydraulic cylinder, driving gear is meshed with driven gear.The blocking device of ejector rob trolley provided locking is installed on the firm banking, when ejector rob trolley provided drive hollow shaft and push rod, when preceding operating position is walked in the top, blocking device is just automatically with ejector rob trolley provided locking, driving gear moves down on the automatic promotion of the hydraulic cylinder meeting this moment sliding seat band, and driving gear and driven gear are meshing with each other.Motor can be opened automatically and drive driving gear and driven gear rotation, and rotate together driven gear drive hollow shaft and push rod, top, realizes the needs that secondary is nipped.
Advantage of the present invention and good effect:
The present invention does not add rotating mechanism compared with prior art on ejector rob trolley provided, do not increase ejector rob trolley provided load; Do not adopt shuttle-type gears engaged, needn't increase the gear width; Do not adopt the friction pulley transmission, can not produce skidding.In a word, mechanism of the present invention is simpler, reliable transmission, and accident rate reduces, and can enhance productivity.
Description of drawings
Fig. 1 is a structure diagram of the present invention
1----push rod 2----vehicle frame 3----wheel 4----track 5----hollow shaft among the figure
6---driven gear 7----slideway 8----sliding seat 9----motor 10----hydraulic cylinder
11----driving gear 12----blocking device 13----firm banking 14---bearing
Specific implementation method:
Shown in figure (1), the hollow shaft 5 that front end and push rod 1 link together is installed in by bearing can be on the vehicle frame 2 of the dolly of walking on the track 4 by wheel 3, and the rear end of hollow shaft 5 is equipped with driven gear 6.Described rotating mechanism is meant hydraulic motor 9 that is installed on the sliding seat 8 and the driving gear 11 that freewheel clutch is installed on it, sliding seat 8 can be moved up and down on ground way 7 by hydraulic cylinder 10 controls, under the piston rod of hydraulic cylinder 10 promotes, driving gear 11 and driven gear 6 are meshed, and the blocking device 12 of ejector rob trolley provided locking is installed on the firm banking 13.When being with hollow shaft 5 and push rod 1 to walk preceding operating position, blocking device 12 is with ejector rob trolley provided locking when ejector rob trolley provided, and at this moment, hydraulic cylinder 10 promotes sliding seats 8 automatically and moves down on ground way 7, and driving gear 11 and driven gear 6 are meshed.Hydraulic motor 9 starts, and drives driving gear 11 and driven gear 6 rotations, drives hollow shaft 5 and push rod 1 and top rotation again, and the pipe secondary is nipped in realizing producing.After secondary was nipped, the top rotated under the effect of pipe, at this moment, was contained in the power source that freewheel clutch in the driving gear 11 cuts off rotating mechanism automatically, and hydraulic motor 9 quits work.After waiting to roll end, hydraulic cylinder 10 moves upward, and driving gear 11 is thrown off with driven gear 6, and a working cycles is finished in the ejector rob trolley provided operating position, back that turns back to.
