Description
Technical field
The utility model relates to a kind of tubing and cuts off equipment, specifically relates to a kind of cutting, the circular tube slitting mill of 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 whole mechanism complexity, the production cost height, and feed synchronized movement difference easily breaks down.For solving the hydraulic radial feed mode, cause mechanism's complicated problems, in disclosed bibliographical information, invent two rotary bodies of a kind of employing gear mechanism control and can produce speed discrepancy, utilize 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, because the interruption cam bit that adopts cooperates with the rolling cut device, and promptly can only admission.Like this after a cut-out job is finished, during next work to be recycled, wherein related withdrawing mode need be reversed and be finished withdrawing.Therefore, this mechanism not only causes the impact of mechanism in using, but also has influenced operating efficiency, also brings operational inconvenience simultaneously.So can not reach desirable effect in actual applications, must be improved and improve.
The utility model content
The purpose of this utility model is for addressing the above problem, and the circular tube slitting mill that provides a kind of advance and retreat of cutting knife to carry out continuously.
Inventor of the present utility model, cooperates with pairing rolling and cutting mechanism by a rotary body end face in two relative rotary body being changed over the forward and back cutter control curve that head and the tail connect through the further investigation practice.Finished the utility model on this basis.
Realize that this novel concrete technical solution is: have the edge cam ring that the control advance and retreat cutter that rotates to it is installed on rotating cylinder; At the described rotating disk that is connected with rotating cylinder one gear being installed meshes with tooth bar knife rest, tooth bar vertical and that level is arranged in a crossed manner respectively; This is nibbled bar knife rest one end hobboing cutter is housed, and tooth bar one end is equipped with the rolling and cutting mechanism that roller is formed, and cooperates with the edge cam loop contacts by roller.
In this is novel, have a cylindrical void on the described tooth bar knife rest, be used for tooth bar and intersect and to pass cylindrical void on this tooth bar knife rest, make tooth bar knife rest and tooth bar carry out horizontal or vertical displacement mutually by this cylindrical void, realize the cutter of advancing and retreat with this.
In this was novel, the cam contour of described edge cam ring was complete one all curves that head and the tail alternately are connected to form more than at least two.
Circular tube slitting mill of the present utility model because of the advance and retreat cutter curve that has adopted the edge cam ring to form, is mated the rolling and cutting mechanism of installation, can finish tubing cutting forward and back cutter continuously.Therefore, has high efficiency, the simple and convenience operation of whole mechanism.In addition, this slitting mill structural design uniqueness has rack drives one gear of roller by edge cam ring contour curve control, drive the tooth bar knife rest and on hobboing cutter finish the action of advance and retreat cutter.Therefore, this edge cam ring, rolling and cutting mechanism are to implement key of the present utility model.
Description of drawings
Fig. 1 is this novel structural representation.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, to this novel being described in further detail.
By Fig. 1, shown in Figure 2 circular tube slitting mill, comprise that a rotating cylinder 7 that has gear 8 is installed on the frame 6.Installation one has the edge cam ring 10 of gear 9 on these rotating cylinder 7 front cylinder, and this edge cam ring 10 can rotate synchronously with respect to rotating cylinder 7.The cam ring profile of described edge cam ring 10 is complete one all curves that plural at least head and the tail alternately are connected to form.Gear 9 which is provided with and gear 8 respectively with driving shaft 2 on the gear 5 and gear 3 engagements that are provided with, described driving shaft 2 one ends are installed on the belt wheel 1 of a drive unit.In order to realize that edge cam ring 10 can produce a speed discrepancy with respect to rotating cylinder 7, having adopted gear 9 on the edge cam ring 10 with gear 8 on the rotating cylinder 7 number of teeth difference to be arranged respectively is Z
9＜Z
8And a clutch 4 is set on the driving shaft 2 between this gear 5 and the gear 3, this gear 5 is installed on the clutch.Like this when clutch 4 separates, edge cam ring 10 be rotated tube 7 have with between rotate synchronously; When clutch 4 is in engagement state, because the speed ratio between gear 5 gears 9 is less than the speed ratio between gear 3 and the gear 8, so the rotating speed of this edge cam ring 10 produces leading rotation greater than the rotating speed of rotating cylinder 7.And utilize this characteristics, the rolling and cutting mechanism that is cooperated with it to cooperate and carry out work.Fixedly install a rotating disk 13 in the end of this rotating cylinder 7, a tooth bar knife rest 15 that hobboing cutter 16 is housed is set in 13 radial grooves that have by changeing.One cylindrical void 17 is arranged on this tooth bar knife rest 15.In this cylindrical void 17, intersect and pass a horizontally disposed tooth bar 12.One end of this tooth bar 12 is provided with roller 11, the other end and gear 14 engagements; This gear 14 meshes with vertically disposed tooth bar knife rest 15 again.Like this when the cam curve of roller 11 on edge cam ring 10 moves to the peak of cam, the tooth bar 12 that is applied to it in the time of these roller 11 rotations produces an axial displacement, and with gear 14 engagement, gear 14 clockwise rotates and entad produces with 15 engagements of tooth bar knife rest that feed force makes hobboing cutter 16 incisions by circle of contact pipe simultaneously again; When the cam curve of roller 11 on edge cam ring 10 moved to the minimum point of cam, 12 reverse 14 inverse times of displacement drive gear of tooth bar rotated, and drive tooth bar knife rest 15 simultaneously and drive hobboing cutter 16 withdrawings to top offset, wait for next working cycles.
Gear 14 in above-mentioned is installed on the rotating disk 12 by support body.
The concrete operation principle of this device is: when clutch 4 is released state, belt wheel 1 by motor drives driving shaft 2 rotations, by 8 engagements of the gear on gear on it 3 and the rotating cylinder 7, rotating cylinder 7 is rotated, driving the edge cam ring 10 that is installed on it simultaneously rotates with speed with it, roller 11 on this rolling and cutting mechanism is in the minimum point of edge cam ring 10 cam curves, and be off working state this moment.When clutch 4 is engagement state, by 9 engagements of the gear on gear 5 and the edge cam ring 10, make the rotating speed of edge cam ring 10 produce leading rotation greater than the rotating speed of rotating cylinder 7, and drive tooth bars 12 roll displacements along cam profile curve effect roller 11, act on gear 14 simultaneously and forward rotate to produce and entad move and cut pipe with tooth bar knife rest 15 engagements that have hobboing cutter.After pipe cuts off, when roller 11 is crossed the cam surface peak, clutch 4 is separated, under action of centrifugal force, by tooth bar knife rest 15 centrifugal motion driven gears 14 backwards rotation, make roller 11 be in edge cam ring 10 cam surface minimum points to finish withdrawing, wait for next working cycles.
