Abstract
The utility model relates to a feeding mechanism of a cold pilger mill, which comprises a lead screw supporting seat, two lead screws, lead screw nuts, bevel gears, a motor and a feeding trolley, wherein the two lead screws are both fixedly mounted on the lead screw supporting seat; the feeding trolley is sleeved on the two lead screw; the motor is mounted on the feeding trolley and connected with a pair of bevel gears; a hollow shaft is arranged on the bevel gears; a pinion wheel is arranged on the hollow shaft; a pair of lead screw nuts with gears is arranged on the two lead screws; and the pinion wheel is meshed with the pair of lead screw nuts. The feeding mechanism adopting the technical scheme has the favorable effects of simple structure, lead screw fixation, convenience in mounting adjustment and long service life.
Description
Technical field
The utility model relates to field of machining, is specifically related to a kind of feed mechanism of cold pilger mill.
Background technology
The feed mechanism of cold pilger mill in the past, no matter it still is the motor single driving based on mechanical system, all is to drive the function that the feeding dolly is realized the feeding of raw material tubing through the leading screw rotation; Because the body of pipe mill is longer; The required instantaneous acceleration of transmission is bigger, therefore must adopt thicker long leading screw, and the diameter of general leading screw reaches 100mm; Length reaches 10000mm even longer, and the type that has also needs the leading screw more than two.Owing to the time that feeding is required is very short; Require the acceleration of moment very big to leading screw; In 0.1s, will turn round 1 circle and stopping in order to let before the feeding dolly and then the power that consumes on leading screw is very huge, accumulates over a long period to produce very large waste; Because whole inertia causes greatly starting and braking moment is bigger, be difficult to realize that accurately control and service life are short in addition.
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, leading screw is fixed, it is easy to adjust to install and the feed mechanism of the cold pilger mill of long service life.
For realizing above-mentioned purpose, the utility model provides following technical scheme: a kind of feed mechanism of cold pilger mill comprises leading screw supporting seat, leading screw, feed screw nut, bevel gear, motor and feeding dolly; Said leading screw has two, and said two rhizoid thick sticks all are fixedly mounted on the leading screw supporting seat, and said feeding dolly is sleeved on the two rhizoid thick sticks; On the said feeding dolly motor is installed; Said motor connects bevel-gear sett, and said bevel gear is provided with hollow shaft, and said hollow shaft is provided with pinion; The feed screw nut of a pair of band gear is installed, said pinion and the engagement of a pair of feed screw nut on the said two rhizoid thick sticks.
Through adopting technique scheme; When sending dolly work to, leading screw does not rotate, and rotates but drive hollow shaft by motor through the bevel-gear sett transmission; Pinion drives the feed screw nut rotation of a pair of band gear on the hollow shaft, thereby realizes that sending dolly work to sends to and fast forwarding and fast rewinding.
The utility model further is set to: described motor can also be installed in leading screw supporting seat one end, is provided with reducing gear and links to each other with motor, and said reducing gear is provided with polished rod, and said polished rod is provided with the polished rod gear, said polished rod gear and feed screw nut engagement.This setting, leading screw are fixed equally, are exactly that motor position is provided with difference.
The utility model has the advantages that: leading screw is fixed, and is convenient to install adjustment, and the suffered moment of torsion of leading screw reduces, reduces stressed, raising service life; Mechanism structure is simplified, and practices thrift cost, and rotary inertia reduces, and cuts down the consumption of energy.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the structure chart of the utility model embodiment 1;
Fig. 2 is the structure chart of the utility model embodiment 2.
The specific embodiment
Referring to accompanying drawing 1, the feed mechanism of the disclosed cold pilger mill of the utility model comprises leading screw supporting seat 1, leading screw 2, feed screw nut 5, bevel gear 6, motor 7 and feeding dolly 8; Said leading screw 2 has two, and said two rhizoid thick sticks 2 all are fixedly mounted on the leading screw supporting seat 1, and said feeding dolly 8 is sleeved on the two rhizoid thick sticks 2; Motor 7 is installed on the said feeding dolly 8; Said motor 7 connects bevel-gear sett 6, and said bevel gear 6 is provided with hollow shaft 3, and said hollow shaft 3 is provided with pinion 4; The feed screw nut 5 of a pair of band gear is installed, said pinion 4 and a pair of feed screw nut 5 engagements on the said two rhizoid thick sticks 2.
During present embodiment work, leading screw 2 does not rotate, and rotates but drive hollow shaft 3 by motor 7 through bevel-gear sett 6 transmissions, and pinion 4 drive feed screw nuts 5 rotate on the hollow shaft 3, sends to and fast forwarding and fast rewinding thereby realize sending to dolly 8 work.
Referring to accompanying drawing 2; Embodiment 2 is exactly on the basis of embodiment 1, and the position of motor 7 has been changed, and concrete technical scheme is following: described motor 7 can also be installed in leading screw supporting seat 1 one ends; Being provided with reducing gear 9 links to each other with motor 7; Said reducing gear 9 is provided with polished rod 10, and said polished rod 10 is provided with polished rod gear 11, said polished rod gear 11 and feed screw nut 5 engagements.
During embodiment 2 work; Leading screw 2 does not rotate, and drives polished rods 10 by the motor of leading screw supporting seat 1 one ends 7 through reducing gear 9 and rotates, and the polished rod gear 11 on the polished rod 10 also rotates thereupon; And drive feed screw nut 5 rotations, send to and fast forwarding and fast rewinding thereby realize sending to dolly 8 work.
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.
