The feeding trolley also comprises an oil cylinder, a shifting fork, a pair of gears and a transmission shaft, wherein the oil cylinder is fixed on the trolley box body through a bolt; the shifting fork is connected with a piston rod of the oil cylinder through a pin shaft; the transmission shaft is arranged on the trolley box body; the pair of gears is respectively arranged on the transmission shaft and the hollow shaft and is meshed with each other; the chuck is connected with the middle part of the shifting fork; a bearing is arranged on the chuck; and the middle part of the shifting fork is pushed against the bearing. Through the technical scheme, the feeding trolley has the favorable effects of being simple in structure, rapid and reliable in action and correct in feeding and capable of clamping the chuck at any position of tube blanks.
Description
Technical field
The utility model relates to the cold pilger mill technical field, is specifically related to the dolly of sending on a kind of cold pilger mill.
Background technology
The dolly of sending on the conventional cold rolling pipe machine mainly contains little box body, nylon nut, slide plate; Hollow shaft, compositions such as panel turnover mechanism, aborning; For guaranteeing in the operation of rolling must existing sending to, make pipe by certain angle rotation again, sending dolly to is exactly the task of sending to of taking on pipe.During work, pipe is by after sending dolly to and being pushed into foremost, and the cold pilger mill main frame stops, and new pipe material loading is sent little vehicle tail end to sending on the lathe bed, delivering to.Send the dolly rewind down to, turnover panel backs down under the effect of pipe, and after sending dolly to and retreating to pipe, turnover panel is closed under spring action.Through adjustment, the cold pilger mill host-initiated is sent dolly to and is begun the worker and advance.There is following shortcoming in the dolly of sending to of this structure, and in sending dolly rewind down process to, pipe is often dragged by turnover panel and retreats, and needs workman's aid in treatment.After rewind down was accomplished, because core bar is crooked or biasing, turnover panel can't auto-closing under spring action, need artificial aid in treatment.In the whole process, all need the workman to supervise, at any time aid in treatment.In addition, the passive revolution of hollow shaft increases the pipe steering resistance, makes revolution can not guarantee to put in place, influences production tube inwall quality.
Summary of the invention
To the deficiency that prior art exists, the purpose of the utility model be to provide a kind of simple in structure, be swift in motion reliable, send to accurately and chuck can be clipped in the dolly of sending on the cold pilger mill of pipe optional position.
For realizing above-mentioned purpose, the utility model provides following technical scheme: the pipe on a kind of cold pilger mill is sent dolly to, comprises little box body, hollow shaft, chuck and claw; Said hollow shaft is installed on the little box body, and said catch jacket is in chuck, and said chuck is socketed on the hollow shaft; Also comprise oil cylinder, shift fork, gear, power transmission shaft; Said oil cylinder is through being bolted on the little box body, and shift fork is connected with the piston rod of oil cylinder through bearing pin, and power transmission shaft is installed on the little box body; A pair of gear is contained on power transmission shaft and the hollow shaft respectively and is meshing with each other; Said chuck is connected with the shift fork middle part, and said chuck is provided with bearing, and said shift fork middle part compresses bearing.
Through adopting technique scheme, oil cylinder control chuck is sent to and is difficult for dragging pipe in the dolly rewind down process and retreats.Because the closed claw of chuck acts on the pipe, therefore send dolly to and can retreat to the optional position and stop, can restarting the worker and advance; After need not to retreat to pipe, send the dolly stroke like this to and not limited by pipe, can greatly shorten and send lathe bed length to; Make that the complete machine requisite space obtains practicing thrift, make its structure simpler, chuck is closed under the oil cylinder effect; It is reliable to be swift in motion, and it is auxiliary to need not the workman.Send in the dolly, power transmission shaft drives the hollow shaft revolution, and claw and pipe turn round synchronously, send to accurately, have guaranteed production tube inwall quality.
The utility model further is set to: on the said little box body and shift fork below is provided with back shaft, and said back shaft two ends are connected to the shift fork bottom, and chuck is withstood at said back shaft middle part.This setting, shift fork rotates around back shaft, can drive the chuck thruster of turning left, and makes things convenient for chuck work.
The utility model has the advantages that: the chuck of the utility model has replaced traditional panel turnover mechanism; And because the closed claw of chuck acts on the pipe; Therefore send dolly to and can retreat to the optional position and stop, can restarting the worker and advance, after need not to retreat to pipe; Send the dolly stroke like this to and not limited by pipe, and simple in structure, be swift in motion reliable and send to accurately.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the left view of the utility model embodiment;
Fig. 3 is the vertical view of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, send dolly on the disclosed a kind of cold pilger mill of the utility model, comprise dolly casing 1, hollow shaft 3, chuck 7 and claw 8; Said hollow shaft 3 is installed on the dolly casing 1, and said claw 8 is enclosed within the chuck 7, and said chuck 7 is socketed on the hollow shaft 3; Also comprise oil cylinder 4, shift fork 5, gear 10, power transmission shaft 2; Said oil cylinder 4 is through being bolted on the dolly casing 1, and shift fork 5 is connected with the piston rod 41 of oil cylinder 4 through bearing pin, and power transmission shaft 2 is installed on the dolly casing 1; A pair of gear 10 is contained on power transmission shaft 2 and the hollow shaft 3 respectively and is meshing with each other; Said chuck 7 is connected with shift fork 5 bottoms, and said chuck 7 is provided with bearing 6, and said shift fork 5 middle parts compress bearing 6.
On the said dolly casing 1 and shift fork 5 belows are provided with back shaft 9, and said back shaft 9 two ends are connected to shift fork 5 bottoms, and chuck 7 is withstood at said back shaft 9 middle parts.
The operation principle of the utility model: during work, pipe is by after sending dolly to and being pushed into foremost, and the cold pilger mill main frame stops, and new pipe material loading is sent little vehicle tail end to sending on the lathe bed, delivering to.Send the dolly rewind down to, retreat certain stroke after, need not pipe after, can clamp chuck 7, claw 8 acts on the pipe that (clamping process: oil cylinder 4 promotes shift fork 5 left, and chuck 7 makes claw 8 move to the axle center through taper seat, thereby clamps pipe; Unclamping of pipe is the reverse of above-mentioned action, and promptly oil cylinder 4 promotes shift fork 5 to the right, and chuck 7 makes claw 8 move to the outer ring through taper seat, unclamps pipe); Through adjustment, cold pilger mill host-initiated, pipe are sent dolly to and are begun the worker and advance.
The rotation of pipe: power transmission shaft 2 and a pair of gear 10 drive hollow shafts 3 and rotate together with chuck 7, and when pipe was tightened by claw 8, claw 8 had been with the intermittent together rotation of pipe.
The foregoing description is to the specific descriptions of the utility model; Only be used for the utility model is further specified; Can not be interpreted as the qualification to the utility model protection domain, the technician of this area according to the content of above-mentioned utility model the utility model is made some nonessential improvement and adjustment all falls within the protection domain of the utility model.
