Abstract

The present invention conventionally cuts pipes and welds separate pipes in a 45 ° direction at right angles to each other. Since it takes a lot of manpower and time, it is difficult to fit the cut material due to the error of cutting, and if the angle is not right and there is a gap (space), it is necessary to close the gap by welding and then grind. In order to solve this problem, which is not very precise and generates a lot of defects, there are a lot of raw material loss and work efficiency is deteriorated, the vertical drive body moving up and down is installed in the horizontal drive unit moving left and right. The torch is positioned on a pipe (material) seated between the rollers that decelerate and rotate on both sides of the lower part. By Will was by the automatic operation program of the control box is fully automatic with no consumption of manpower and time by spewing plasma fever and finely cut, while improving the work efficiency was designed to reduce the raw materials.

Description

C / N plasma plasma auto cut equipment {C · N · C plasma pipe auto cut equipment}

The present invention relates to an automatic cutting machine for CNC plasma pipes. When cutting pipes and welding them in the 'T' shape, etc., the precise cutting that comes into close contact without the occurrence of a gap in the joint part is performed automatically. To improve productivity.

Conventionally, when welding and connecting a separate pipe in a right angle or a 45 ° direction by cutting the pipe, the cutting part is drawn with paper, wrapped around the pipe to be cut, lined with a stone pill, and oxygen cutting is manually performed along the marked line. In case that it takes a lot of time and time, it is difficult to fit the cut material due to the cutting error, and if the angle is not exactly right and there is a gap (space), it was necessary to close the gap by welding and then grind, Not only did the defect rate occur a lot, but also the loss of raw materials, and the working efficiency was reduced.

The present invention has a vertical drive body to move up and down in the horizontal drive unit to move left and right in order to eliminate the closed end as described above, the torch of the front surface of the vertical drive center is seated between the rollers to decelerate rotation on both sides of the lower It is designed to reduce raw materials while improving work efficiency by completely and precisely cutting the plasma high heat by automatically controlling the automatic control program of the control box in close proximity to the pipe (material).

The guide sliders 12, 12 ', 13 and 13' on all sides of the vertical driving body 11 are adhered to the opposite surfaces of the vertical guide rails 10 and 10 'of the vertical guide rails. The vertical ball screw 16, which is fixed to the servomotor 15 shaft, is screwed in, and the angle check level 19 is fixed to the servomotor 17, which is installed on the vertical drive member 11, on the expansion shaft 18. Fixing and interlocking the hose inlet pipe 21 equipped with the torch 20 at the end, a plurality of rollers 23, 23 ', 23' on the front substrate 22. (24) (24 ') (24 ') .. speaking the rotating shaft 25 (25') fixed at equal intervals The spur gears 26 and 26 'are mounted, and the chain 29 is fitted to the reduction gear 28 shaft of the servomotor 27 so as to be operated automatically by the control of the control box 30.

'31' is the pipe, '32' is the indicator hand, '33' is the instrument operation panel, '34' is the pressure gauge, '35' is the gas automatic switchgear, '36' is the fixed disk, and '37' is the long hole. Is displayed.

The present invention as described above is connected to the switch and the hose and the power supply to the oxygen tank, high pressure gas cylinder (not shown) and the like formed on the rotary shafts 25, 25 'rolled on the front substrate 22 at equal intervals. Roller (23) (23 ') (23') .. (24) (24 ') (24') .. Pipe the pipe to be cut between and select the program with the control box 30 and press the button. When the horizontal ball screw 9 is rotated while the servomotor 8 fixed below the transverse 2 supporting the supports 1 and 1 'is rotated, the screw nut 7 fixed to one side of the horizontal drive unit 6 is rotated. The guide rail 3 on the upper side of the transverse 2 is moved smoothly by the guide slider 5 'and the guide slider 5 on the inside of the' c'-type moving body 4 and the lower guide rail 3 '. The servomotor 8 is automatically stopped and the servomotor 15 fixed to the horizontal drive unit 6 is operated. Rotating the cylinder 16 causes the horizontal drive unit to descend when the torch 20 and the servomotor 17 integrated with the vertical drive unit 11 are lowered by the screw nut 14 fixed to the vertical drive unit 11. Guide sliders 12, 12 ', 13 and 13' of the vertical drive body 11 are respectively adhered to both of the guide rails 10 and 10 'of (6), so as to lower the earth accurately without shaking. When the end nozzle portion of the cutout 20 is close to the pipe to be cut, the servomotor 15 is automatically stopped and at the same time, the angle checking level 19 fixed to the speech shaft 18 while the servomotor 17 is finely driven according to the input program. And tilting the angle of the torch 20 at the end of the inlet pipe 21, the instructions on the front of the angle checking level 19 confirm the inclination, and the gas, oxygen, and air pressure are supplied through a hose inserted into the inlet pipe 21. When ignited during simultaneous ejection, the front substrate is ejected at the start of cutting while releasing high heat in (a) of FIG. 6 (a). (22) When the servo motor 27 on one side is finely moved at the same time, the chain 29 caught in the reduction gear 28 shaft gear is interlocked and the spur gears 26 and 26 'are gradually turned in the same direction to rotate the shaft 25 (25). '23' (23 ') and (23') formed at equal intervals between the pipes to be cut between 24, 24 'and 24'. 8) When the movement of the horizontal drive unit 16 in the direction of arrow (e) continues while the microscopic movement is performed, the torch 20 ejects high heat and cuts to (b) of FIG. C) When cutting is continued, the torch 20 is gradually displaced and inclined by reverse driving of the servomotor 17, and the pipe interlocking when the servomotor 27 is also driven in the opposite direction as before is also reversed. When guiding the moving direction of the tunchi 20, the servomotor 8 fixed to the transverse 2 continues to move in the same direction to move the horizontal drive unit 6. When moving slowly and cutting from (C) to (D), the inclined direction of the torch 20 and the driving direction of the servomotor 27 are maintained in the same direction, but the servomotor 8 below the transverse 2 is The drive is reversed and the horizontal drive unit 6 is pushed in the direction of the arrow (bar) to cut slowly. Finally, when cutting from (d) to (a), the torch (20) is operated by reverse driving of the servomotor (17). ) Is gradually displaced and the servomotor 27 which drives the pipe is again driven in the same direction as the reverse drive (A) to (B), but the servomotor 8 is the same direction as (C) to (D). The operation is driven by automatic operation as the input operation program is cut automatically, the cutting is completed and at the same time oxygen and high pressure gas is automatically cut off the supply is extinguished and the servo motor 27 and the vertical driving body (forward and reverse drive pipe) 11) the angle of the sieve torch 20 integrated with As the servo motor 17 to be adjusted is stopped, the servo motor 15 fixed to the horizontal drive unit 6 rotates to raise the vertical drive body 11, and the servo motor 8 installed on the transverse 2 rotates. While the action of moving the horizontal drive unit 6 to its original position is made at the same time, and if the program is operated by the control box 30 according to the pipe cutting part and shape, it can be automatically cut in any form.

The present invention is designed to operate automatically or manually by controlling the control box according to the cutting position and shape of the pipe, so that accurate work without errors can be performed while saving time, manpower and raw materials, and improving efficiency economically. It is effective to mass-produce products with utility.
