[Industrial applications]

  The present invention is intended for header molding in order to facilitate the work of mounting the cutter. The present invention relates to a shearing device for a linear material.

[0002]

[Prior art]

  Conventionally, as an apparatus for shearing a linear material in header molding, Attach the shear die a to the end of the supply side, and immediately before the shear die a. -A swing part b that swings back and forth at a right angle to the central axis direction of the die a is provided, and the swing part b The cutter d is attached by adjusting bolts c, c '... The center of the cutter hole e penetrating in the center of the upper part of the tool is aligned with the center axis of the shear die a. Centering work is performed, and the linear material w is passed through the shear die a and the cutter hole e. And insert it into the hole edge f of the cutter hole e and the shear die a by the swinging part b. A shearing device of the type that shears the linear material w to a predetermined length is used.

[0003]   In such a shearing device, when the diameter of the linear material w is changed, the cutter d and the shear -When replacing both or one of the dies a, loosen all adjustment bolts c, c '... After removing the cutter d, a separate cutter d is attached to the swinging part b in a substantially fixed state, and The center axis of the shear die a by wearing and tightening the adjusting bolts c, c '... While aligning the center of the cutter hole e on top, mount the cutter d on the swinging part b in a completely fixed state. The centering work for wearing is required again, and in the shearing device, the cutter d is substantially in the center part. Since it is located in the center, the centering work of the cutter d is in a groping state. However, it is extremely difficult to perform centering work and has a drawback that it requires a long time.

[0014]   Reference numeral 23 denotes a hinge board formed below the fixed holder 11, and the hinge board 23 is Has a pin hole 24, and a hinge board 23 is sandwiched from both sides in the lower part of the detachable holder 12. A hinge parallel plate 25 in a held state is formed, and a pin hole 26 is formed in the hinge parallel plate 25 to fix it. Insert pin 27 into pin hole 24 of fixed holder 11 and pin hole 26 of removable holder 12 to hinge The part 13 is formed.

[0015]   28 and 28a are adjusting bolts for positioning and fixing the cutter 5 in the mounting opening 4 of the swinging portion 3. The adjusting bolts 28, 28a are arranged at right angles to the central axis of the shear die 2. At the same time, the adjusting bolts 28, 28a are screwed into the swinging portion 3 so that the tips of the adjusting bolts 28, 28a are attached to the mounting opening. It projects from the portion 4 and is in contact with the cutter 5.

[0016]   In another embodiment, the surface of the cutter knife 10 is shaken from the edge of the cutter hole 20. A groove 29 is provided on the moving direction side of the moving part 3 and extends from the groove 29 to fix the holder 11. A groove 30 is provided on the.

[0017]   Next, the operation of the shearing device for the linear material in the header molding according to the present invention will be explained. When revealed,   First, align the center of the cutter hole 20 of the cutter knife 10 with the center axis of the shear die 2. Centering work by finely adjusting the adjusting bolts 28 and 28a so that Is fixedly mounted in the mounting opening 4, and then the linear material W is passed through the insertion hole 6 of the shear die 2. Then, the cutter 5 is inserted forward into the cutter hole 20 of the cutter 5, and the swinging part 3 is moved forward to insert the shredder. -Since the linear material W is sheared by the shearing blade portion 7 of the die 2 and the edge of the cutter hole 20. is there.

[0018]   Then, when replacing the cutter 5 when changing the diameter of the linear material W, etc. While not loosening all the adjustment bolts, the holder 8 is attached to the mounting opening 4 of the swinging portion 3. Adjusting bolt that contacts the upper surface of the detachable holder 12 Loosen the socket 28 with a spanner, etc., and then swing the removable holder 12 around the hinge 13.

The fitting ridge 21 of the ter knife 10 is fitted, and the stopper 18 is fitted into the rotation stop hole 22. As the end 19 is inserted, the outer diameter is the same and the inner diameter of the cutter hole 20 is different. Set the knife 10 into the fixed holder 11 and rock the detachable holder 12 to Attach the demounting holder 12 to the fixed holder 11 in a joined state, and finally tighten the adjusting bolt 28. The cutter 5 is attached to the mounting opening 4 of the swinging portion 3.

[0019]   Further, when the linear material W is sheared to a length shorter than the thickness of the cutter 5, a groove 29 is provided. Using the cutter knife 10 and the fixed holder 11 with the groove 30, use the stopper (Fig. Set the tip of (not shown) to a predetermined position in the cutter hole 20, and reciprocate the swing part 3. At this time, the tip of the stopper (not shown) passes through the grooves 29 and 30 to fix the linear material W. Of.

[0020]

[Effect of device]

  In short, the present invention is applicable to the case where the shear die 2 is attached to the end of the feeding portion of the linear material W. Is attached to the mounting opening 4 of the swinging portion 3 disposed immediately before the tip side of the shear die 2. In the shearing device consisting of the cutter 5, the fixed holder 11 and the detachable holder 12 are connected. A fixed mounting hole 9 is formed on the mating surface, and a cutter hole 20 is provided at the center of the mating surface and a shader. Form a cutter knife 10 with a larger diameter than the chair 2, and attach and detach the holder knife to the fixed holder 11. Der 12 is connected by hinge 13 and fixed mounting holes for fixed holder 11 and detachable holder 12 The cutter 5 is integrally configured so as to hold the cutter knife 10 at 9, and the fixed holder 11 The lower part is fixed to the lower part of the mounting opening 4 of the swinging part 3, and the adjusting button of the mounting opening 4 is adjusted. Since the belts 28 and 28a are fixed by abutting against the holder 8, the conventional shearing device for linear materials is used. Like the cutter used for installation, loosen all adjustment bolts and remove the cutter when replacing. It was necessary to remove the cutter and center the cutter again. Position the fixed holder 11 of the holder 8 on the swing part 3 with the adjusting bolts 28, 28a. The mounting and removal holder can be removed by loosening only the mounting bolt 28. Oscillate the dar 12 and remove the cutter knife 10 and separate the knives with the same outer diameter. Just set the cutter knife 10 in the fixed holder 11 and attach the detachable holder 12 The center of the cutter hole 20 of the cutter knife 10 is aligned with the center axis of the shear die 2. Therefore, the troublesome centering work at the time of replacement can be omitted, and the replacement time can be shortened. It is possible to achieve 1/20).

[0021]   Also, since the cutter knife 10 has a larger diameter than the shear die 2, the shear die 2 Similarly, when exchanging only, detach the holder 12 by swinging and detach the cutter knife 10. Since it can be replaced from the mounting opening 4 of the swinging part 3 by removing it, the replacement work can be simplified. In addition, the fixed holder 11 and the detachable holder 12 can be separated by swinging by the hinge portion 13. Therefore, when fixing the fixed holder 11 and the detachable holder 12 when replacing the cutter knife 10, It can be very easy to join.

[0022]   Further, the detachable holder 12 is attached to the holder 11 on the forward direction side of the swinging portion 3 to hold the holder. Since it is formed as a dar 8, the linear material W is sheared on the backward movement side of the hole edge of the cutter hole 20. Therefore, the force applied when the linear material W is sheared is fixed to the swing part 3. Since it almost acts on the fixed holder 11 of, the detachable holder 12 side is not affected at all. Therefore, the main body 1 is a combination of a cutter knife 10, a fixed holder 11 and a detachable holder 12. Even the body can be highly durable, and its practical effects are enormous. It
