Description
Technical field
The invention belongs to the feeding device of a kind of feeding device of tubing, particularly a kind of cold-rolling pilger mill or perhaps the servo turning feeding in continuous material feeding arrangement system of cold pilger mill.
Background technology
Cold-rolling pilger mill needs to finish the revolution of pipe off and on and send action near the extreme position of the front and back of frame stroke, and this is a minimum time range.Therefore the material-uploading style of cold-rolling pilger mill and the revolution feed mechanism of milling train have great related because traditional cold pilger mill mostly adopts the mechanical type revolution to send machine mechanism, complex structure, so mostly adopt the shutdown material-uploading style, operating efficiency is very low.
Summary of the invention
The objective of the invention is to design a kind of transmission mechanism simple, under the prerequisite of guaranteeing accurately to send to, significantly improve mill speed, have the servo turning feeding in continuous material feeding arrangement apparatus of the cold pilger mill of not shutting down feeding in continuous material.
Technical scheme of the present invention is, designs a kind of servo turning feeding in continuous material feeding arrangement system of cold pilger mill, it is characterized in that: the two cover feed mechanisms that can independently control are arranged before and after pipe moves forward direction; Wherein, feed mechanism comprise reduction box, send motor to, feeding lathe bed, feeding trolley, worm couple, leading screw and turning motor; Send motor to by being connected with worm couple in the reduction box, again by worm couple by leading screw with place two transmission screw sockets of sending cart stationary in two lathe beds, motor is sent in starting to, sends motor to and will drive feeding trolley clamping pipe and move forward feeding; The single-revolution motor is by being connected with worm couple in the reduction box, and worm couple is connected with feed rod, and feed rod is connected with gear drive in the feeding trolley, and feed rod rotates and drives the interior gear drive of feeding trolley, advances while pipe is rotated; The front and back feed mechanism is alternately finished a pipe forward and is moved forward.
The feed rod that described turning motor drives can be one, and the interior gear drive of an end of a feed rod and preceding feeding trolley is connected; The other end of a feed rod is connected with the gear drive of back in the feeding trolley.
The feed rod that described turning motor drives can be two, and two feed rods are connected by worm couple with a turning motor respectively; Two feed rod other ends are connected with gear drive in the feeding trolley of front and back.
Reduction box in the described feed mechanism can be shared one of a front and back feed mechanism, also can be that the front and back feed mechanism respectively has one.
Leading screw in the described feeding lathe bed can be two, two rhizoid thick sticks respectively with feeding trolley on the socket of transmission screw; Between the two rhizoid thick sticks is feed rod, and two rhizoid thick sticks are sent motor to and are connected with one by a worm couple respectively.
Advantage of the present invention is: use many servomotors by leading screw and feed rod in former and later two lathe beds of worm gear difference transmission; drive two tube billet chuck alternations in former and later two lathe beds; thereby the realization milling train is not shut down feeding in continuous material, the working system of sending to continuously.Operating rate and output have significantly been improved.Pipe both can carry out twice revolution, once sent to, also can carry out twice revolution, send to for twice in a stroke, roll-force is evenly distributed, axial force significantly reduces, can shut out the less high-quality precision tube of external diameter and wall thickness deviation, the lumber recovery height, simultaneously very flexible on milling train adjustment and processing arrangement.
