Description

  The present invention is used for processing such as cutting a corrugated resin tube such as a PF tube or a CD tube or making a cut in the longitudinal direction. In particular, the size and processing means of the corrugated resin tube to be processed are arbitrarily set. The present invention relates to a vertical cutting tool for corrugated resin pipes that can be changed.

  In cable wiring work in electrical work, for example, there is work to protect the cable by covering the end of the cable or cable rack or all screws with a PF pipe. In this case, it is necessary to cut the PF pipe into a predetermined length or cut the longitudinal direction. However, the work to process corrugated resin pipes such as PF pipes using cutters and electric knives becomes unstable due to the hardness and wave shape of the resin pipes. It is a dangerous work.

  On the other hand, as a tool for making a cut in the longitudinal direction of a corrugated resin pipe such as an FEP pipe, a FEP pipe longitudinally splitting tool described in Patent Document 1 has been proposed. This longitudinally split tool is provided with a rotary blade that cuts the wall of the FEP pipe in a straight line in the longitudinal direction when the FEP pipe is expanded in a substantially planar shape. Then, a substantially cylindrical FEP tube guide portion for inserting and supporting the FEP tube, and a cutting instrument fixing portion for fixing the rotary blade to the opening of the FEP tube guide portion are provided.

  Further, Patent Document 2 discloses a corrugated tube cutter that cuts a valley portion of a flexible corrugated tube. In this cutter, after the corrugated tube is pushed into the recess of the cutter body and positioned in the cutting posture, the valley bottom portion of the corrugated tube is cut with the cutting edge of the cutting blade. As a result, the valley bottom of the corrugated tube can be cut reliably.

JP 2008-178922 A Japanese Patent No. 4845521

  However, since the longitudinally splitting tool described in Patent Document 1 is a tool used to longitudinally split the FEP pipe and expand the FEP pipe into a substantially flat shape, it is not possible to make a cut along the longitudinal direction of the corrugated resin pipe. Even if possible, the corrugated resin tube cannot be cut horizontally. Therefore, it is difficult to cut a corrugated resin pipe such as a PF pipe by using this vertically divided tool.

  On the other hand, the corrugated tube cutter described in Patent Document 2 has a configuration in which the corrugated resin tube can be cut horizontally but cannot be cut in the longitudinal direction of the corrugated resin tube. Therefore, this corrugated tube cutter is also not suitable for the work of vertically dividing a corrugated resin tube such as a PF tube.

  As described above, the conventional tool is limited to one function of vertically dividing the corrugated resin tube with one tool or cutting it horizontally. Therefore, a tool suitable for machining such as vertically dividing or cutting the PF pipe has not yet been provided, and machining of the PF pipe is still difficult and dangerous.

  Therefore, the present invention was created to solve the above-described problems, and when processing a corrugated resin pipe such as a PF pipe, the corrugated resin pipe can be divided vertically or cut horizontally. In addition, it is an object of the present invention to provide a vertically divided cutting tool for corrugated resin pipes that can be adapted to a plurality of sizes of corrugated resin pipes.

  In order to achieve the above-mentioned object, the first means in the present invention is to sandwich the cutter body 10 provided with the cutting blade 11 slidable at the tip, and the side surface of the corrugated resin tube Q provided at the tip of the cutter body 10. And a wave that fixes the direction of the cutting blade 11 that makes a cut in the longitudinal direction of the corrugated resin pipe Q or the direction of the cutting blade 11 that cuts the corrugated resin pipe Q laterally by the sandwiching body 20. It is a vertical cutting tool for a resin tube, and the sandwiching body 20 includes a vertically split pinching portion 21 that forms a pair for fixing the cutting blade 11 in a direction along the longitudinal direction of the corrugated resin tube Q, and a corrugated resin tube. And a pair of cutting and clamping portions 22 for fixing the cutting blade 11 sideways with respect to Q, and the cutting blade while sandwiching the corrugated resin pipe Q by selecting the vertically divided holding portion 21 or the cutting and holding portion 22 11 is configured to be cut.

  In the second means, the sandwiching body 20 includes four fixed arms 23 that extend obliquely radially from the tip of the cutter body 10 about the cutting blade 11 toward the tip of the cutting blade 11. When the fixed arm 23 is selected and the corrugated resin tube Q is clamped, the two pairs of fixed arms 23 are clamped so that the cutting blade 11 is oriented along the longitudinal direction of the corrugated resin tube Q. The vertically sandwiched portion 21 is defined as a portion between the two fixed arms 23 sandwiched in a state in which the cutting blade 11 is in a lateral direction with respect to the corrugated resin tube Q. is there.

  3rd means WHEREIN: The said cutter main body 10 is provided with the handle part 12 which accommodates the said cutting blade 11 so that sliding is possible, and the fixing tool 13 which adjusts the length of the said cutting blade 11 and fixes it to the handle part 12. FIG. The cutting blade 11 is slidably accommodated at the center of the sandwiching body 20 and the cutting blade 11 is projected from the tip of the sandwiching body 20.

  As in claim 1 of the present invention, the clamping body 20 includes a vertically split clamping portion 21 that fixes the cutting blade 11 in a direction along the longitudinal direction of the corrugated resin tube Q, and the corrugated resin tube Q. On the other hand, a pair of cut and sandwiching portions 22 for fixing the cutting blade 11 in the horizontal direction are provided side by side, and the vertically split sandwiching portion 21 and the cutting and sandwiching portion 22 are selected and the corrugated resin tube Q is inserted into the cutter body 10 By being configured to process, when processing the corrugated resin pipe Q such as a PF pipe, it is possible to divide the corrugated resin pipe Q vertically with a single tool or cut it horizontally. In addition, since the orientation of the cutting blade 11 of the cutter body 10 is stable by the sandwiching body 20, extremely safe and accurate processing can be performed.

  As in claim 2, the sandwiching body 20 includes four fixed arms 23 that extend obliquely radially from the distal end portion of the fixed body 10 about the cutting blade 11 toward the distal end direction of the cutting blade 11, Since these vertically fixed holding portions 23 and the cutting and holding portions 22 are provided side by side with these fixed arms 23, the fixed body 10 is directed toward the distal end of the cutting blade 11 even if the diameter of the corrugated resin tube Q is changed. Thus, the four fixed arms 23 extended in four oblique directions always come into contact with the side surface of the corrugated resin pipe Q. Therefore, it can be applied to a plurality of sizes of the corrugated resin pipe Q. Furthermore, when the corrugated resin pipe Q is a PF pipe, it can also be used for processing a multi-layer PFD or a single-layer PFS.

  As in claim 3, the cutter body 10 includes a handle portion 12 that slidably houses the cutting blade 11, and a fixture 13 that adjusts the length of the cutting blade 11 and fixes the cutting blade 11 to the handle portion 12. Since the cutting blade 11 is slidably stored at the center of the sandwiching body 20 and the cutting blade 11 is projected from the tip of the sandwiching body 20, the operator is similar to a commercially available cutter. The cutter body 10 can be operated with the same feeling.

  The cutting tool of the present invention is used when cutting the corrugated resin pipe Q. The configuration of the present invention includes a cutter body 10 having a cutting blade 11 and a sandwiching body 20 that sandwiches the corrugated resin tube Q so that the orientation of the cutting blade 11 of the cutter body 10 can be selected and fixed by the sandwiching body 20. It is composed.

  The cutter main body 10 is a portion having a slidable cutting blade 11 at the tip, and includes a handle portion 12 and a fixture 13 (see FIG. 1). The handle portion 12 is a sheath-like portion that houses the cutting blade 11 in a slidable manner. The fixture 13 is a screw-like member that adjusts the length of the cutting blade 11 and fixes it to the handle portion 12. And it is comprised so that the cutting blade 11 may protrude inside the clamping body 20 mentioned later.

  The illustrated fixture 13 has a structure that penetrates the cutting blade 11 through a washer 14 and is fixed to a fixed female screw 15 (see FIG. 1). And the length of the cutting blade 11 is adjusted along 12 A of slide groove parts of the handle part 12 (refer FIG. 2).

  The sandwiching body 20 is a part that sandwiches the side surface of the corrugated resin tube Q, and is provided at the tip of the cutter body 10 (see FIG. 1). This sandwiching body 20 is provided with a vertically sandwiching part 21 and a cutting and sandwiching part 22. The vertically split holding portion 21 is a portion that fixes the direction of the cutting blade 11 along the longitudinal direction of the corrugated resin pipe Q, and is used when the slit is cut vertically in the longitudinal direction of the corrugated resin pipe Q. (See FIG. 3). On the other hand, the cutting and clamping portion 22 is a portion that fixes the cutting blade 11 sideways with respect to the corrugated resin tube Q, and is used when the corrugated resin tube Q is laterally cut (see FIG. 4).

  The illustrated clamping body 20 includes four fixed arms 23 that extend radially in four directions toward the oblique tip with the cutting edge 11 protruding and retracting from the cutter body 10 as the center (see FIG. 3). . Then, by changing the direction of the corrugated resin pipe Q sandwiched between the fixed arms 23, the vertically split sandwiching portion 21 and the cutting sandwiching portion 22 are selectively used (see FIG. 4).

  That is, when the corrugated resin tube Q is sandwiched between the fixed arms 23, the cutting blade 11 is oriented vertically along the longitudinal direction of the corrugated resin tube Q. It is set as the split clamping part 21 (refer FIG. 5). When this vertically split holding portion 21 is clamped on both sides of the corrugated resin pipe Q, the cutting blade 11 is fixed in a state along the longitudinal direction of the corrugated resin pipe Q (see FIG. 6). Therefore, the protruding length of the cutting blade 11 of the cutter body 10 is adjusted, and the tip of the cutting blade 11 is inserted into the side surface of the corrugated resin tube Q in a state where the side surface of the corrugated resin tube Q is sandwiched by the vertically split holding portion 21. When the cutter body 10 is slid along the longitudinal direction of the corrugated resin tube Q, the vertically dividing operation of the corrugated resin tube Q by the cutting blade 11 can be performed accurately.

  On the other hand, when the corrugated resin tube Q is sandwiched between the fixed arms 23, the cutting and clamping portion 22 is formed between the two pairs of fixed arms 23 in which the cutting blade 11 is oriented transversely to the corrugated resin tube Q. (See FIG. 7). When the corrugated resin tube Q is clamped by the cutting and clamping part 22, the cutting blade 11 is fixed laterally with respect to the longitudinal direction of the corrugated resin tube Q (see FIG. 8). Therefore, when the tip of the cutting blade 11 is inserted into the side surface of the corrugated resin tube Q in a state where the corrugated resin tube Q is sandwiched by the vertically divided clamping portion 21, and the cutter body 10 is rotated, the corrugated resin by the cutting blade 11 is obtained. The cutting operation of the pipe Q can be performed accurately (see FIG. 7).

  Furthermore, since the fixed arm 23 is extended obliquely radially toward the distal end direction of the cutting blade 11 with the cutting blade 11 of the cutter body 10 fitted with the fixed body 10 as a center, the diameter of the corrugated resin tube Q is increased. Even if they are different, they can be clamped in the fixed arm 23 (see FIGS. 5 and 7). In the illustrated example, two types of corrugated resin pipes Q, a large-diameter resin pipe Q1 and a small-diameter resin pipe Q2, are shown, but it is possible to adapt to more diameters.

  In addition, the shape of the cutting blade 11 and the cutting blade holding part 12 of the cutter main body 10 of the present invention, the configuration of the sandwiching body 20 and the like are not limited to the illustrated examples, and the scope of the present invention is not changed. The design change is free. Moreover, although demonstrated as a tool which processes the corrugated resin pipe | tube Q in this invention, it can be used also for the process of the other pipe | tube which can be cut | disconnected with the cutting blade 11.
