Abstract
The present invention relates to a generating machine for the cross section of a circular pipe, which comprises a rotating cylinder and a rotating disk arranged on the rotating cylinder, wherein the radial end of the rotating disk is hinged with a connecting rod hinged with a hob frame movably arranged on the rotating cylinder. A friction decelerating device is arranged on the rotating disk at the end matched with the rotating cylinder, and one end of the rotating cylinder is directly connected with an electric machine belt wheel. The present invention has the advantage of simple structure, cutter feeding and cutter retracting can be controlled by changing an included angle between the connecting rod and the hob frame, and the generating machine is suitable for generating pipes with different specifications.
Description
Technical field
The present invention relates to a kind of tubing and cut off equipment, specifically relate to a kind of circular tube slitting mill that is used for cutting disc scroll-diced chipless.
Background technology
At present, the circular cross-section tubing slitting mill of using on the tubulation production line, the radially feed of its hobboing cutter all is to adopt hydraulic way, needs configuration hydraulic system and movement transferring.Have complicated integral structure, production cost height, and feed synchronized movement difference breaks down easily.Cause mechanism's complicated problems in order to solve the hydraulic radial feed mode, in disclosed bibliographical information, invent two rotary bodies of a kind of employing gear mechanism control and can produce speed discrepancy, utilization relative rotation speed high turn on cam bit is set, radial end face by cam bit cooperates the feed force that entad forms with the rolling cut cutter, finish radially rolling cut, no matter this slitting mill all is better than hydraulic way from the design of mechanism or on using.But unique problem is to adopt multilevel gear drive mechanism, and need the speed discrepancy by Clutch Control rotating cylinder, inner barrel; Because the interruption cam bit that adopts cooperates with tourelle, promptly can only admission, like this after a cut-out job is finished, to be recycled next when working, wherein related withdrawing mode need be reversed and be finished withdrawing.Therefore, not only cause the impact of mechanism in the use of this mechanism, also influenced operating efficiency, and whole mechanism complexity can be brought operational inconvenience.So fail to reach desirable effect in actual applications, must be improved and improve.
Summary of the invention
The objective of the invention is for addressing the above problem, and a kind of circular pipe section roll-cutting machine of the cutter of can advancing and retreat continuously is provided.
The present inventor by the abutting end to two relative rotary body, is provided with a deceleration device through further investigation and practice, the advance and retreat cutter of a rolling and cutting mechanism of control; With utilize rotary body on directly be connected driving mechanism.Finished the present invention on this basis.
Realize that technical solution of the present invention is: a kind of circular pipe section roll-cutting machine comprises rotating cylinder and goes up the rotating disk of installing that wherein the other end at described rotating cylinder is equipped with the movable carriage that an end has hobboing cutter by uniform radial groove; The other end of described movable carriage and connecting rod are hinged correspondingly; The other end of every described connecting rod all is articulated in the rotating shaft of the radial outer end that is installed in the rotating disk end face; The contact site of described rotating disk and rotating cylinder is provided with Friction speed-reducing device; Described rotating cylinder one end directly is connected with electrical machine belt pulley.
When Friction speed-reducing device acts on the rotating disk, make the counter motion of rotating disk generation with respect to rotating cylinder, produce the centripetal force feed by connecting rod and knife rest, in order to cut off tubing; After Friction speed-reducing device loosened, knife rest is withdrawing under action of centrifugal force.
In the present invention, the angle between described connecting rod and hinged described movable carriage is 100 °-180 °.Along with the variation of angle realizes control advance and retreat cutter.
In the present invention, more than one connecting rod being set on the described rotating disk connects with the corresponding knife rest that has hobboing cutter.
Circular pipe section roll-cutting machine of the present invention is formed connecting rod advance and retreat cutter mechanism because of having adopted on the rotating disk by hinged connecting rod and knife rest; And with rotating disk that rotating cylinder matches on a Friction speed-reducing device is installed, the effect by this device has realized that rotating disk produces the backward rotation with respect to rotating cylinder, cuts or non-cutting movement in order to control link advance and retreat cutter mechanism.Thereby this connecting rod is to implement key of the present invention with cutter frame mechanism that has hobboing cutter and set Friction speed-reducing device.Solved the cam mechanism control hobboing cutter that existing slitting mill adopts, and the whole mechanism complicated problems brought of multi-gear assembly transmission mechanism.
Description of drawings
Fig. 1 is the structural representation of invention.
Fig. 2 is that the A of Fig. 1 is to schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
Circular pipe section roll-cutting machine by shown in Figure 1 comprises a frame 3, by the bearing that is provided with on it one rotating cylinder 2 that can rotate relative to frame 3 is installed.Described rotating cylinder 2 one ends are connected with motor drive pulley 1, can directly control the rotation of rotating cylinder 2 like this.Installing one on the opposite side of this rotating cylinder 2 can be with the rotating disk 5 of rotating cylinder 2 rotations.On the contact site of this rotating disk 5 and rotating cylinder 2 Friction speed-reducing device 4 is set.When friction deceleration device 4 acts on rotating cylinder 2, produce the backward rotation that a frictional force produces with respect to rotating cylinder 2 rotating disk 5; And Friction speed-reducing device 4 is when throwing off, and this rotating disk 5 can be with rotating cylinder 2 with changeing.The other end at described rotating cylinder 2 is equipped with the movable carriage 8 that an end has hobboing cutter 9 by uniform radial groove, the hinged connecting rod 7 of the other end of its knife rest 8; The other end of this connecting rod 7 is hinged with the rotating shaft 6 of the radial outer end that is installed in rotating disk 5 end faces.Therefore, in the design of rolling and cutting mechanism, form 100 °-180 ° angle between this connecting rod 7 and the knife rest 8.Control the advance and retreat cutter of hobboing cutter 9 by changing its angle.
In the present invention, the length of related connecting rod 7 should could form angle like this greater than itself and knife rest 8 hinges to the radial distance between the rotating shaft 6, and entad centripetal force is provided.
In the present invention, reducing of described connecting rod 7 and 8 angles of knife rest is by centrifugal action, makes rotating disk 5 and rotating cylinder 2 produce relative motion and produces the withdrawing motion.
Involved Friction speed-reducing device 4 in above-mentioned is finished products of selecting market sale for use.
Fig. 2 has provided the A of Fig. 1 to the position.Comprise rotating cylinder 2 and on rotating disk 5.When rotating cylinder 2 rotates by the up time direction, by the rotation that makes rotating disk 5 produce an inverse time direction after the friction catch, the connecting rod 7 of hinged end is swung like this, and act on knife rest 8 and entad move, angle theta between its connecting rod 7 and the knife rest 8 is changed from small to big promptly 100 ° of-180 ° of scope feeding feeds, until hobboing cutter 8 cut-out pipes.After the rolling cut feeding is finished, after the disengaging friction braking, make the connecting rod 7 on the rotating disk 5 finish the withdrawing motion with rotating cylinder 2 generation relative motions.Thereby guaranteeing under the continuous motion situation, realizing the advance and retreat cutter.
