The present invention relates to a wire cutting machine that is used to cut wires such as various wires to a certain length regardless of their diameter and length. The present invention relates to a wire cutting machine which can cut a pipe or the like, and after cutting these wires, the coating on both ends thereof can be stripped.

In general, the wire cutting machine is divided into mechanical and electronic according to the control method of the cutting roller and cutting blade to transfer the wire. The mechanical is mainly dependent on the cam device, and the electronic is dependent on the electromagnetic clutch by the jaw. All use the drive source as a motor.

However, the conventional wire cutting machine, both mechanical and electronic, install a transfer roller on both sides of the front of the body, and install a fixed blade having a fixed upper and lower operating width between the transfer rollers, respectively. By connecting the servo motor (servo motov) capable of forward and reverse rotation in the user, if the user inserts a wire with a constant diameter between the transfer rollers and then operates the motor, the wires are transferred by the rotating feed rollers. When a certain length is transferred to the knife blade is working to cut the wire.

Therefore, the wire cutting machine like this requires three motors to drive the transfer roller and the blades. These motors are all expensive servo motors, which increases the price of the wire cutting machine itself, and also because of the fixed blade type, the diameter and length of the wire Whenever the change was followed by the inconvenience of having to replace the blade.

In addition, such a wire cutting machine was the main purpose of the cutting operation, so that the stripping process must be carried out in order to separate the coating after cutting, causing a decrease in productivity and labor cost.

In order to solve this problem, the present invention forms a wire-cutting machine of a combination of mechanical and electronic forms, which combines a cam device and an electronic device to enable cutting and stripping regardless of the diameter and length of the wire without replacing the blade. In addition, it is possible to cut tubes and small pipes, and to reduce manufacturing costs by installing only one servomotor in the main body.

Referring to the operation of the present proposal configured as described above and its effects and effects are as follows.

First, the present invention inserts a plurality of strands of wire A wound around the support plate 100 on the side of the automatic holding device or the roller into the guide hole 102a of the detection plate 102, and then inserts it into the roller 101. Pass through in a zigzag form, turn the handle 23 'on one side to move the upper feed roller 98 upward, and then move the wire A back and down the guide hole 103a of the guide 103. After inserting the feed roller 105 between the transfer rollers 98 and 99 and through the guide hole 104a of the guide 104, turn the handle 23 to move the upper feed roller 98 'to the lower feed roller ( 99 ') and rotate the adjusting knob 52 of the wire diameter adjusting device 50 to adjust these upper and lower feed rollers 98' and 99 'to the diameter of the wiper A. .

The operation may be performed as follows. That is, when the one-side handle 23 is rotated, the roller 26 is moved by the operating shaft 24 and the operation section 25 integrally with the handle 23. Since it is pushed while rolling contact with the outer surface of the gearbox 18 with the bracket 27 rotates about the linkage shaft 19, at the same time the movable shaft 17 together with the gearbox 18 long hole (11a) Therefore, the upper and lower feed rollers 98 'and 99 are spaced apart from each other because they rotate upward.

At this time, the long hole 11b of the front plate 11 is formed in an arc shape around the linkage shaft 19 'so that the connection state of the connecting gear 43 and the driven gear 41 is maintained as it is, and the upper feed roller ( When the 98 is rotated upward, the tension spring 95 'is relaxed, and after releasing from the handle 23', the compression force of the tension spring 95 'and the gear box ( The wire A between the upper and lower conveying rollers 98 and 99 is gripped while descending by the self-weight including 18 ').

In addition, the upper feed roller 98 'of the other side is similarly rotated up and down by the handle 23 only in the rotational direction opposite to the upper feed roller 98, and the wire diameter adjusting device 50 protrudes with the outside. When the adjusting knob 52 is turned, the thrower bolt 53, which is screwed with the nut 51, 51 ', pushes the bracket 27 while moving left and right, so that the user can adjust the adjusting knob 52. The gap between the upper and lower feed rollers (98 ', 99') can be adjusted according to the diameter of the wire (A), and the protrusions (53a) formed at the head of the stopper bolt (53) once adjusted. Relaxation of the stopper bolt 53 is prevented by the ball bearing 55 of the leaf spring 54 coupled to the), even if the hand is released from the adjusting knob 52, unless the artificial force is applied.

In this way, the wire A is inserted between the upper and lower feed rollers 98, 98 ', 99 and 99' of both sides to be pressed, and then the adjustment knob 64 of the blade adjusting device 60 is used. To adjust the cutting and stripping position of the movable blade 108, and adjust the stripping length by using the adjusting knob 82 of the wire stripping length adjusting device 80.

The operation at this time is as follows.

That is, when the adjustment knob 64 is rotated, the roller 62 is screwed through the teeth and bolts 63 as the user moves up and down, so that the roller 62 is the first, second, and second of the cutting cam 28. 3, while visually confirming the position of the movable blade 108 when in contact with the active portions 28a, 28b, 28c, adjust the position of the movable blade 108 in accordance with the diameter of the wire (A) and the thickness of the coating. The control knob 82 on one side may adjust the distance between the stopper bolt 81 and the rack gear 31, which are stripping lengths of the wire A. FIG.

Then, by using the adjusting knob 73 of the wire back stripping adjusting device 70, the rear stripping state of the wire A is adjusted while checking the connection state of the rack gear 31 and the pinion gear 44.

Press the operating sweep (8) in the adjusted state as described above to turn on the power, adjust the front stripping length, wire (A) length, quantity button of the instrument panel (9) and then of the motor box 113 When the on / off switch 112 is “on” and the operation switch 8 is pressed once again to start, the servo motor 14, the reduction motor 15, and the motor box 13 are turned on. The motor operates to cut and strip off.

That is, the rotational force of the servomutter 14 is driven through the pulleys 32, 33, the timing belts 46, 47, and the pulleys 34, 35, 36, 37 of the motor shaft 14a. 16) (16 ') and the interlocking shaft (19) (19'), and the rotational force of the double interlocking shaft (19) (19 ') is again connected to the coupling gear (42) (43) and driven gear (40) (41). As the movable shafts 17, 17 'are rotated through the upper and lower feed rollers 98, 98, 99 and 99', the wires A held between them are rotated. Will be transferred.

In addition, the rotational force of the reduction motor 15 rotates the interlocking shaft 20 through the drive gear 38 and the connecting gear 39 of the motor shaft 15a, thereby causing the stripping cam fitted to the interlocking shaft 20 ( As the 29 rotates, the rack gear 31 which is in contact with the roller 72 is linearly reciprocated. At the same time, the rotational force of the linkage shaft 20 is pulley 96, time belt 48, and pulley 97. As the driven shaft 21 is rotated through), the cutting cam 28 fitted to the driven shaft 21 rotates to operate the rack gear 30 which is in contact with the roller 62 through the roller 62, up and down. As the rack gear 30 rotates the pinion shaft 22 through the pinion gear 22a, the movable blade 108 in which the pinion gear 49 of the pinion shaft 22 is toothedly connected through the rack gear 108a. ) Will operate up and down.

Hereinafter, the cutting and stripping operation will be described step by step.

First, when the wire A is transferred by the set length while the wire A is being transferred as shown in FIG. 4, the operation of the servo motor 14 is stopped and the upper and lower transfer rollers 98, 98 ', 99 ( 99 'also stops, and the wire A is stopped. At the same time, the roller 72 of the rack gear 31 comes out of the groove 29b of the stripping cam 29 and comes into contact with the active part 29a. At this moment, the roller 62 of the rack gear 30 descends while being in contact with the highest first active part 28a of the cutting cam 28 so that the movable blade 108 cuts the wye A. .

At this time, when the rack gear 30 is lowered, the compression spring 66 is compressed, the tension spring 67 is relaxed, and the compression and tension spring 66 (the moment the roller 62 leaves the first active part 28a) By the restoring force of 67, the rack gear 30 and the movable blade 108 are returned to their original positions by interlocking the pinion shaft 22.

When the cutting is completed as described above, the moment the roller 62 is inserted into the groove 28e out of the first active part 28a of the cutting cam 28 as shown in FIG. 5, the rack gear 30 and the movable blade ( 108 is returned to its original position by the restoring force of the compression and tension springs 66 and 67, and at the same time the roller 72 fits into the groove 29b of the stripping cam 29, which is continuously rotating, and compresses and tensions at this moment. As the rack size gear 31 rotates in the direction of the arrow by the restoring force of the springs 75 and 76, the lower feed roller 99 'on one side is rotated in the reverse direction to reverse the cut wire A' by the stripping length. At the same time, the servo motor 14 rotates the upper and lower transfer rollers 98, 98 ', 99 and 99' on both sides in the reverse direction to reverse the wire A of the uncut portion.

When the cut wire A 'is thus retracted by the stripping length, the roller 62 comes into contact with the second active part 28b of the cutting cam 28 as shown in FIG. 6, and the movable blade 108 descends again. Since only the rear coating of the wire A 'is cut off and fixed, the roller 72 comes into contact with the active part 29a of the stripping cam 29 again, so that the rack gear 31 rotates as shown by the arrow to move downward on one side. Rotate the roller 99 'forward.

Therefore, the upper feed roller 98 'connected together with the lower feed roller 99' also rotates while the upper feed roller 98 'is rotated to transfer the wire A' therebetween, so as to cover the rear side of the wire A '. This peels off and falls.

When the back stripping of the wire A 'is completed, the roller 62 is inserted into the groove 28f again as shown in FIG. 7 and the movable blade 108 is raised, and the servomotor 14 is transferred to the upper and lower sides of both sides. The rollers 98, 98 ', 99 and 99' are rotated forward to discharge the cut and stripped wire A 'to the outside, and the uncut wire A is transferred by the cutting length.

In this case, as shown in FIG. 8, the roller 62 comes into contact with the third active part 28c of the cutting cam 28 again, and the movable blade 108 descends while cutting only the covering of the front stripping portion of the wire A while stopping. The roller 72 is inserted into the groove 29b of the stripping cam 29 so that the rack size gear 31 reversely rotates the lower feed roller 99 'so that the front cover of the wire A is peeled off. Subsequently, when the front coating of the wire A is peeled off, the roller 62 is inserted into the groove 28d of the cutting cam 28 to raise the movable blade 18 as shown in FIG. 9, and the servomotor 14 is lifted. The lower feed rollers 98, 98 ', 99 and 99' are rotated forward so that the wire A is fed by the cutting length and returned to the initial state as shown in FIG.

Thereafter, such an operation is repeated to cut and strip the wire A by a predetermined length.

During the above operation, when the rack gear 31 reversely rotates the lower feed roller 99 'on one side to strip the wire A, only the lower feed roller 99' is driven by the electromagnetic clutch 45. ), So that the upper and lower feed rollers 98 and 99 and the servo motor 14 on the other side do not interfere at all, and the diameter of the detection plate 102 installed on the support plate 100 is maintained while the operation is in progress. The other defective wire is detected, and the plurality of rollers 101 apply tension to the wire A to prevent it from being entangled or loosened so easily that it is not entangled.

In addition, when the wire A 'in the cut and stripped state falls on the rotating plate 15, the rotating plate 115 rotates once by the motor shaft 114 so that the wire A' inside thereof falls on the wire support plate 15. The wire support 110 is always in a neat state of the wire (A ') is placed in sequence, when a certain amount is stacked, the user is to bundle and move it.

As described above, the present invention combines a cam device and an electronic device, and it is free to cut and peel regardless of the diameter and length of the wire A without replacing the blade, and uses only one servomotor 14 for cost. It can contribute to the reduction, and can cut not only the wire (A) but also the tube or the small pipe.

In addition, cutting and stripping multiple wires (A) at once can be mass-produced and the cutting area of the fixed and automatic blades (107, 108) is "V" shaped, so that the cutting area is wider, so the defective rate This is less.

And once the work is completed wire (A ') is arranged neatly arranged on the wire support plate 11 of one side is easy to transport and packaging.
