The specific embodiment
Below in conjunction with Fig. 1 to Fig. 7 the present invention is described in further detail:
Pipe no-chip cutting machine of the present invention comprises frame 1, also comprise tubing length measuring device 2 and PLC control device (not shown), length measuring device will be counted long signal and be sent to described PLC control device when carrying tubing 5, the PLC control device is controlled cutter sweep 3 along machine frame movement according to the long signal of this meter, and makes cutter sweep carry out fixed length to tubing to cut.In implementation process, frame 1 is provided with line slide rail 11, and described PLC control device control cutter sweep moves along this slide rail.Be provided with the heater 4 that tubing is heated between cutter sweep and length measuring device, the heating-up temperature of this heater is controlled by the RKC temperature controller, thereby with cutting after the tubing preheating deliquescing, not only can improve cutting effect, and improves cutting efficiency.
In the present invention, described sleeve 321 is outer to be positioned at cutter and bracing or strutting arrangement both sides and to be arranged with left and right sides supporting plate 33,34 with sleeve rotating, one end of described knife rest motion guide piece and support movements guide pad is affixed with left socle plate 33 respectively, and its other end is all opened from the bar shaped gathering sill 35 of close tubing one side direction away from the tubing lopsidedness; Described knife rest and bracing frame right side all are connected with a slide block 36, radially be provided with on the described right support plate 34 two line slideways, 341, two slide blocks respectively correspondence be installed on two line slideways, can guarantee the stable and cutting accuracy of cutting machine; The described other end of knife rest and bracing frame all be equipped with guide wheel 37, two guide wheels respectively correspondence be installed in two gathering sills.In motion process, described PLC control device control left socle plate is along the sleeve axially-movable, usually but PLC control device control cylinder promotes or the axially-movable of pulling left socle plate, the described end of knife rest motion guide piece and support movements guide pad is done axially-movable with it under the effect of left socle plate, thereby whole knife rest motion guide piece and support movements guide pad are moved axially, because described gathering sill tilts, the height difference that the same radial position before and after motion of the gathering sill of axially-movable is corresponding, therefore, under guide wheel can not the condition of axially-movable, guide wheel moves to the post exercise height and position along gathering sill from the front height and position that moves, and realizes radial motion.Among the present invention, the knife rest that guide wheel connects and bracing frame have limited guide wheel by slide block and line slideway axially-movable, guide wheel is done radial motion with this understanding, thereby be with respectively movable knife rack and bracing frame to do radial motion, the radial motion band cutting blade of knife rest and bracing frame and support crop rotation radial motion; When blade and the left radial motion of support wheel, two slide blocks affixed with knife rest and bracing frame move along line slideway.This cutting machine is in when work, and the radial motion of blade and support wheel is in opposite directions or dorsad, and both centers are remained unchanged.The present invention realizes the radial motion of blade and support wheel by PLC control device control knife rest motion guide piece and the axially-movable of support movements guide pad, thereby changes the radial distance between blade and the support wheel, reaches the purpose of blade cuts tubing.
Heater 4 of the present invention comprises that inside is formed with the cartridge heater 41 of tubing heating space, and several heating rods 42 are installed in this cartridge heater, and the heating-up temperature of heating rod is subjected to the control of described RKC temperature controller, and the RKC temperature controller is existing equipment, is not repeated herein.In implementation process, can according to the material of tubing, select the temperature of RKC temperature controller control heating rod; For the softer tubing of material, can also not use heater, it can be by the work of the control of the heating selector switch on device control panel heater stop.The present invention has also adopted length measuring device 2, it comprises the length metering wheel 21 that contacts with tube surfaces, thereby the rectilinear motion of tubing is rotated by frictional force drive length metering wheel, length metering wheel will be counted long signal and be passed to described PLC control device, the PLC control device starts cutter sweep according to the long signal of meter, thereby makes cutter sweep carry out fixed length cutting.
Clamp mechanism of the present invention adopts HALF formula clamping mode, and the PLC control device is prior art, and it can realize control by programming.When work, tubing is drawn by hauling machine, when tubing places heater, heating rod heats tubing at heating space, length measuring device is measured the pipe length that need cut, after reaching preseting length, length metering wheel sends signal to the PLC control device, PLC control device control clamp mechanism clamps tubing rear drive cutter sweep and moves, simultaneously by driven by motor sleeve High Rotation Speed, cutting assembly and bracing or strutting arrangement are set on the sleeve along with rotation, thereby blade and support wheel are also rotated around tubing thereupon together, then make blade and support wheel radial motion by cylinder promotion knife rest motion guide piece and the axially-movable of support movements guide pad, thereby make both gradually near tubing, and then incising pipes, until the tubing cutting is complete.After the tubing cutting was finished, PLC control device control blade movement guide pad and support wheel motion guide piece moved in the other direction, and it is resetted, and then control sleeve and stop the rotation, and last clamp mechanism is unclamped tubing and resetted.
The present invention cuts tubing around the tubing High Rotation Speed by blade, produce the phenomenon of sawdust when having avoided prior art to adopt the saw blade cutting, realized the chipless cutting, raw material have not only been saved, can not cause contamination, and cut surface is smooth smooth, the noise when having reduced the equipment cutting; This cutting machine simple in structure, compact, volume is little, complete machine adopts programmable control, automaticity is high, can carry out fixed length and cut, cutting accuracy is higher, and is simple to operation, reduces the employee work amount; In addition, by can cutting the more tubing of high rigidity to the tubing preheating, good cutting effect, cutting efficiency is high.
Above-mentioned embodiment is only for explanation the present invention's, and be not to be limitation of the present invention, the those of ordinary skill in relevant technologies field, without departing from the spirit and scope of the present invention, can also make various variations and modification, so all technical schemes that are equal to also should belong to category of the present invention.
