Be provided with infrared indicator 16 in the infrared location of said thin plate apparatus for real time tracking 61 and the infrared location of the cut deal apparatus for real time tracking 71.
Principle of the present invention is explained as follows:
Thin plate cutting: because cutting thin plate easy deformation; Adopt water cover 683 water spray coolings to prevent distortion at present; Keep a segment distance between water cover 683 and the thin plate torch head 682; Be thin plate location distance 686,, play the positioning action that cutting torch and steel plate spacing require so that keep respective between thin plate torch head 682 and the cutting plate.The up-down of thin plate cutting torch 68 is realized through Z axis rail 64 by Z axle cylinder 65; Promptly driving the Y axle slide plate 8 that is provided with on it by Y shaft transmission 4 earlier slides; Drive Z axis rail 64,65 slips of Z axle cylinder successively by Y axle slide plate 8 again; Simultaneously, the cylinder arm of Z axle cylinder 65 through spring 66 drive thin plate cutting torch fixture block 67 successively, thin plate cutting torch 68 moves up and down, and can the water cover mouth 685 of water cover 683 bottoms be overlayed on steel plate to be cut.When changing the cutting torch unit, only need pulled down Z axis rail 64 and thin plate cutting torch cover 63 and get final product.
Cut deal cutting: because the temperature in the cut deal cutting is very high; Water cover can not adapt to; So the mode that the cutting cut deal need adopt arc voltage to heighten automatically makes torch head and the dynamically requirement of the preset respective of maintenance of surface of steel plate in the course of work; Preset respective is generally 2 – 6m; Because the distance between torch head and steel plate has only several millimeters, heightens crashproof anchor clamps 76 so designed arc voltage, cut deal cutting torch 72 is contained in arc voltage and heightens in the crashproof anchor clamps 76; And heighten at arc voltage and two steel plates of can the out-of-flatness of invar plate with the torch head that guarantees cut deal cutting torch 72 near switch 762 near switch 761 and an anticollision or cutting off to be housed on the crashproof anchor clamps 76 to arrange not concordant and hit, thereby cut deal cutting torch 72 is effectively protected.Arc voltage is heightened crashproof anchor clamps 76 and is installed in automatic arc voltage and heightens on the cut deal supporting plate 74 that the loop bar axle 751 of controller 752 lower ends connected, and arc voltage is heightened two ends that controller 752 inner automatic arc voltages heighten controller 752 and is connected with microcomputer with loop bar axle 751 and reductor 753, direct current generator 755 respectively automatically.In the use, realize the heightening automatically of torch head of cut deal cutting torch 72 through the monitoring that in the plasma cutting process arc voltage is changed,, satisfy the requirement that presets to guarantee the constant distance between torch head and steel plate in cutting process.Only need the screw that automatic arc voltage is heightened Z axle executing agency 75, cut deal cutting torch cover 73 come loose to pull down during replacing gets final product, and then cut deal cutting torch 72 is inserted arc voltages and heightens in the anchor clamps hole of crashproof anchor clamps 76 and get final product.
In concrete use; Above-mentioned two kinds of cutting torch unit; Be thin plate cutting torch unit 6 with cut deal cutting torch unit 7 change convenient, can be through mutual alternative, make and be used for satisfying the different instructions for use of user in turn, and need not prepare the sheet cutting machine and the cut deal cutting machine of two platform independent.
Tubing cutting: for satisfying the needs of tubing cutting, with the X axle of the CUT X axle as the rotation incising pipes, other designs the Y axle of tubing rotating mechanism 9 as the tubing cutting.
Tubing rotating mechanism 9 is arranged in parallel with base 1; Y axle crossbeam 43 upper edge horizontal line folk prescriptions to extending a cutting torch arm 10 so that tubing cutting torch unit 11 be in tubing 12 center line above, combine simultaneously just can on tubing 12, cut out various straight lines and curvilinear figure by the lengthwise movement that rotatablely moves with X shaft transmission 3 of the micro-processor controlled tubing rotating mechanism 9 of servo-drive system.
The method that tubing rotating mechanism 9 adopts powerful bearing block servomotor 14 directly to be transmitted in bearing block 94 avoided in the prior art since adopt that the intermediate reduction gear device brings driving error; Not only improved running accuracy; Its precision can be the rotating mechanism of employing intermediate reduction gear device more than 5 times; And reduced the noise and the vibration of complete machine, and improved the running smoothness, improved machining accuracy and quality.
Up-down opening and closing roller hunting gear 93 can move, lock along adjustment seat guide rail 92 directions, and therefore tubing cutting torch unit 11 can be well positioned to meet the cutting needs of different length tubing 12 with the lengthwise movement of X shaft transmission 3 along the lengthwise movement of tubing 12.The diameter range of incising pipes 12 of the present invention is generally: Φ 50mm – Φ 300mm, maximum length is 4000mm, also can provide according to customer requirements and can cut bigger pipe diameter, more the present invention of long tube material length to be to satisfy customer requirements.
The transmission effect of ball screw: the X shaft transmission 3 that adopts among the present invention, Y shaft transmission 4 are realized transmission by servomotor, ball screw, and the positioning accuracy of ball screw can reach ± 0.03mm, and repetitive positioning accuracy can reach ± 0.015mm; Its precision is higher than common tooth bar transmission more than 5 times; And the highest movement speed of ball screw transmission can reach 20M/min, and is higher 1.66 times than tooth bar transmission maximum speed 12M/min of the prior art; Not only help improving the cutting work efficiency; And can reduce noise and vibration, improve the running smoothness, thereby improve the cutting accuracy and the surface quality of workpiece.
The in good time following function in infrared location: in thin plate cutting torch unit 6 and cut deal cutting torch unit 7, be provided with the infrared location of thin plate apparatus for real time tracking 61 and the infrared location of cut deal apparatus for real time tracking 71 among the present invention respectively; This design not only can be carried out real-time tracking to cutting process through infrared location apparatus for real time tracking; And the direction that can rotate the infrared indicator 16 that is provided with in the spheroid centre bore of joint in the apparatus for real time tracking of infrared location is arbitrarily accurately aimed at cut point to guarantee ruddiness; Motion discharge to X, Y axle before can being convenient to cut designs, and promptly when not cutting, carries out the discharge setting through software; Then cutting head is moved at X, Y both direction; Ruddiness then shows on steel plate along with the cutting track that X, Y motion will design in advance, if find not reach the effect of meticulous discharge, then can reappear design till satisfaction; Thus, the present invention help rationally, the accurately realization of discharge.
The design effect of processing platform: the processing platform 2 that adopts among the present invention is the nail bed structure; This nail bed structure adopts cheese head screw 21 to press 100mm * 100mm pitch arrays; Sheet material to be cut is put on it; This design can make because of the cheese head screw 21 that influenced by cuts sheet material to damage to be convenient to buying more and to change, and can greatly make things convenient for the user to carry out plant maintenance, reduces use cost.
Therefore, the present invention not only comprehensive strong, be convenient to carry out meticulous discharge, can reduce production costs, cutting accuracy is higher, and noise is lower, vibration is less, smoothness is higher, cut quality is better.
