Description

[Detailed Description of the Invention] The disclosed technology belongs to the technical field of hanging tools used for disassembling, assembling, and transporting work materials such as cutting blades.

Therefore, this invention utilizes a mounting hole such as a socket hole for a device such as a steel material such as a cutting blade or a curved blade used in a press mold, etc., and fits into the mounting hole to attach a hanging wire, etc. This invention relates to the structure of a hanging jig that is suspended and transported via a hook, and in particular, a sleeve with an outer diameter similar to the mounting hole is inserted and fitted, and the hook is screwed into the proximal threaded part of the internal tightening bolt. In addition, this invention relates to a structure of a hanging jig for a workpiece, in which the sleeve is expanded through the chuck groove slit by the tapered surface of the tip circumferential surface, and is crimped and tightened to the inner surface of the mounting hole, thereby making it possible to suspend and transport the workpiece.

As is well known, various materials are used in processing equipment, and for example, in press molds, materials made of steel such as cutting blades and curved blades are assembled and used.

Therefore, the seed material needs to be transported by hanging from a wire for assembly and disassembly, and various mounting holes and assembly holes are drilled for this purpose.

To illustrate with the above-mentioned cutting blade, as shown in Figs. 1 to 4, the cutting blade 1 generally has a socket hole 2 as a mounting hole for assembly, a notch hole 3 for positioning, and a hanging bolt hole 4 for transportation. It is perforated.

Moreover, the holes 2, 3, and 4 are usually drilled together with the machining of the cutting blade 1.

Therefore, there are disadvantages in that the number of machining operations on the workpiece is extremely large, and it is difficult to maintain precision.The work is cumbersome and difficult to manage, as positioning must be performed for each hole machining. There were advantages.

The purpose of this invention is to solve the technical problem of the various working holes of the materials based on the above-mentioned conventional technology. is an excellent material that benefits the field of material utilization in the processing industry by reducing the number of man-hours required for the material by allowing it to be transported using the assembly and mounting holes necessary for its original function. The purpose is to provide a hanging jig structure.

In order to solve the above-mentioned problems, the structure of this invention in accordance with the above-mentioned purpose is that the notch holes for positioning and the mounting holes for assembly are unavoidably machined during machining of the workpiece, and therefore the holes for hanging are No machining is required, which reduces man-hours, and when repairing or replacing the workpiece, the tightening bolt is inserted into a sleeve with an outer diameter slightly smaller than the inner diameter of the mounting hole.
The tightening bolt insertion sleeve is fitted into the mounting hole, the hook is screwed onto the tightening bolt protruding from the base end of the sleeve, the tapered peripheral surface of the tip of the tightening bolt is expanded, and the sleeve is expanded. The main point is that the shank is expanded in diameter through multiple slits in the axial direction of the shank, is crimped and fastened to the mounting hole, and is transported by hanging from the hook for repair or replacement. That is.

Next, one embodiment of this invention will be described below based on FIGS. 5 and 6. In addition, 1st to 4th
Components having the same features as those in the drawings will be described using the same reference numerals.

Reference numeral 1' denotes a cutting edge which is provided to the press mold, and during the molding process, the mounting hole 2 of the tightening socket and the positioning notch hole 3 are set at predetermined positions as shown in Figures 2 and 3. However, the hanging hole 4 shown in FIG. 4 is not drilled.

The mounting hole 2 is also used as a hanging hole.

Thus, 5 is a hanging jig, which forms the gist of this invention, 6 is a cylindrical sleeve,
It can be inserted loosely with an outer diameter slightly smaller than the inner diameter of the mounting hole 2, and a tapered surface 7 with a set angle is formed at the tip, and three tapered surfaces from the tip extend from the outer surface to the inner surface 8 to the middle of the setting of the shank 9. slit 1
0, 10, 10 are allocated.

Reference numeral 11 denotes a fastening bolt, the tip of which forms a tapered surface 12 matching the tapered surface described above, and the upper part of a shank 13 which is inserted into the sleeve 6 and which protrudes from the sleeve 6 is provided with a male thread 14 .

Reference numeral 15 denotes a hook, which is formed in the shape of a ring of a set size, and one part of which has a female screw 16 carved therein to be screwed into the male screw 14, and a wire insertion slit 17 cut out on the side thereof. .

18 is a spacer type washer, which is interposed between the upper end of the sleeve 6 and the hook 15.

In the above structure, when replacing or repairing the cutting blade 1' to the press die, the fastening bolt 11 is inserted from the tapered surface 7 side of the tip of the sleeve 6, and the tapered surface 12 is aligned with the tapered surface 7. In this state, the sleeve 6 is inserted into the mounting 2 of the cutting blade 1'.

Then, the washer 18 is inserted into the head of the tightening bolt 11 at the upper end of the sleeve 6, and finally the hook 15 is attached and the female thread is screwed into the male thread 14 of the tightening bolt 11 and pushed forward.
is pulled relative to the sleeve 6, the tip tapered surface 12 widens the tapered surface 7 of the sleeve 6, and the sleeve 6 has three split slits 10, 10, 10.
is expanded and crimped into the mounting hole 2, and then tightened.

Then, after confirming the degree of tightening, a wire (not shown) is inserted into the hook 15 through the slit 17 and hung, and the hook 15 is transported for repair or replacement.

After use, the lifting jig 5 is removed from the cutting blade 1' by performing the reverse operation to the above-mentioned process.
The hook 15, sleeve 6, and fastening bolt 11 are individually released and stored and managed in a predetermined manner.

It goes without saying that the embodiments of this invention are not limited to the above-mentioned embodiments; for example, various embodiments may be employed, such as adding hard rubber or resin to the outer surface of the sleeve, or mounting a hook on the sleeve. can be adopted.

It goes without saying that the workpieces are not limited to steel materials such as press-type cutting blades and curved blades, but can also be applied to other processed workpieces that have mounting holes for assembly.

As mentioned above, according to this invention, it is basically possible to attach a hanging jig for repair or replacement by using the mounting hole such as a socket hole to the device of the workpiece, so that the hanging jig can be used when processing and forming the workpiece. The drilling process of holes can be omitted, which not only reduces the number of machining operations, but also eliminates the need for complicated positioning during machining, which has the excellent effect of simplifying the molding process. It is played.

Furthermore, although the mounting hole can also be used as a hanging hole, there is an advantage that there is no problem in mounting.

The sleeve is then hooked to the mounting hole by a fastening bolt with a tapered end and screwed onto the fastening bolt to expand the vertical slit and apply surface pressure, allowing it to be used as a kind of anchor bolt. By making it possible to firmly fix the sleeve to the workpiece, there is an effect that there is no risk of the sleeve accidentally falling off during transportation work by suspending it via a hook.

Further, since the fastening bolt is screwed with a hook, the screw fastening force has a tapered surface, producing an excellent effect of generating a strong pressing force.
