Generally, general plane numerical controlled cutting equipment, its cart is X to translation along cart track, and dolly does Y-direction translation, and the motion of X, Y-direction all can co-ordination under program, cut out arbitrary plane curve.If round steel pipe makees pure rolling, then roll one week, round steel pipe centrage is by one perimeter length of translation, and intersection will be launched into a plane curve, and therefore processing round steel pipe intersection with plane numerical controlled cutting equipment is feasible from principle.Rolling to movement progress steel pipe with the X of cart, dolly drives cutting torch to move along Y-direction, the distance of matching intersection difference to steel pipe end, it is possible to cut out by intersection.
Its solution is: by the cart track of universal plane numerical control cutting equipment and the cart that is flexibly connected with it, it is connected with cart rail mounted and with the dolly of cutting torch, the pushing mechanism arranged on cart, and it is arranged on the workpiece roller track on general plane numerical controlled cutting equipment workbench, constitute cutting circular steel pipe intersection processing tool.This cutting circular steel pipe intersection processing tool, copies to, under the G code nc program control that universal plane numerical control cutting equipment is formed, complete the cutting processing of round steel pipe intersection at the intersection processing G code generated by dedicated program.
Described pushing mechanism is made up of the scroll wheel of pushing frame and upper connection thereof.
Described generation intersection processing G code dedicated program is:
1) input chord member, web member specification, and chord member direction vector and chord member and web member intersecting point coordinate related data；
2) according to chord member and web member direction vector, angle between chord member and web member two bar is calculated；
3) web member inner circle girth is divided equally by about 1mm length, all marks are n, obtain and divide equally each point on intersection and arrived chord member, web member intersection point and distance Li (L1, L2, L3 ... Li ... Ln) with web member axis vertical plane, and take lowest distance value Lm4) obtain web member Center Length, deduct above-mentioned two ends lowest distance value Lm, obtain web member cutting length, and export web member cutting length numerical value；
5) web member outer circumference is divided into n section by number of dividing equally identical with inner periphery length, obtains G code X-coordinate, and each equal branch distance Li of web member deducts its corresponding lowest distance value Lm, obtains G code Y coordinate；
6) linear interpolation output processing G code file is pressed.
This utility model uses technique scheme, with the cart track of universal plane numerical control cutting equipment and the cart that is flexibly connected with it, it is connected with cart rail mounted and with the dolly of cutting torch, the pushing mechanism arranged on cart, and the workpiece roller track being arranged on universal plane numerical control cutting equipment workbench is cutting circular steel pipe intersection processing tool, the intersection processing G code that will be generated by dedicated program, copy to universal plane numerical control cutting equipment and form G code nc program, universal plane numerical control cutting equipment is under the control of G code nc program, the cutting processing of round steel pipe intersection can be completed.Due to the plane numerical controlled cutting equipment utilizing factory there is now, equipment investment can be efficiently reduced, reduce cost, and simple to operate.Meanwhile, the intersection smooth surface processed is smooth, and precision is high, can directly use, it is not necessary to carry out manual amendment polishing, can be effectively improved crudy and the efficiency of steel-tube intersection-line.Obvious economic benefit can be produced.
