The drawing apparatus disclosed in Patent Document 1 employs an indirect cooling method in which a flow path of a cooling medium is provided in a frame body for holding a roller dice. Therefore, the heat generated by the roller dies is not absorbed by the cooling medium unless it is transmitted to the frame body through the roller dies and the roller dies. Therefore, the pulling apparatus disclosed in Patent Document 1 can not say that it has a sufficient structure for cooling the roller dies and the bearings, and can not suppress the thermal expansion of the roller dies, fluctuates the wire diameter, and has a problem of high load on the bearings .

In addition, the drawing device disclosed in Patent Document 2 has a structure in which a roller dice is assembled to an eccentric shaft having a flow path of a cooling medium.

[ Further, Dice of (2) At the time of positioning, On the dice (2) It is not necessary to change the position of the rotary shaft 4 relative to the roller 4, so that by means of the first positioning means and the second positioning means, Dice of (2) The position can be adjusted very easily and accurately.

( Example )

Hereinafter, with respect to the wire drawing apparatus 1 (hereinafter referred to as the main wire drawing apparatus) described in the above-mentioned embodiment and the conventional wire drawing apparatus disclosed in Patent Document 2, the time required for the assembly, the time required for adjustment, And compiled in Table 1 below.

Assembly adjustment decomposition Conventional wire cutting device 25-30 minutes 1 minute 5 to 7 minutes This inserting device About 15 minutes 1 minute 3 to 5 minutes

An operator who is not skilled in this cutting device, the conventional cutting device, or any cutting device measured the time required for the assembly, adjustment and disassembly of each cutting device.

As a result, the time required for the assembly was about 25 minutes to 30 minutes for the conventional wire cutting device, whereas that of the conventional wire cutting device was about 15 minutes. The cutting device is not only required to be assembled to a half of the time required for a conventional cutting device but also assembled in a short time of about 15 minutes. Therefore, the cutting device can be regarded as a cutting device requiring little skill of a worker.

This is because the wire cutting device employs a configuration in which the rotary shaft 4 of the roller dice 2 is mounted in a groove formed in the surface of the housing 5. By this configuration, It is possible to omit a time-consuming work which needs to be carried out carefully, i.e., it is inserted directly into the frame body.

Next, the adjustment time was 1 minute in both the main cutting device and the conventional cutting device, or the cutting device, and at least no difference was found in the time required for the adjustment.

However, in this cutting device, the position of the rotary shaft 4 supporting the roller dice 2 in the axial direction is set by the right pressing piece 28a, which is the first positioning means provided on the frame 3, The both ends of the housing 5 are pressed in the axial direction (left-right direction) of the rotating shaft 4 by using the right pressing screw 29a and the left pressing piece 28b and the left pressing screw 29b, Execute position setting.

Since the position of the roller dice 2 is set by adjusting the position of the housing 5 supporting the rotary shaft 4 instead of adjusting the position of the rotary shaft 4 in this way, It is possible to easily set the position of the roller dice 2 while avoiding shortage or insufficient holding of the roller dice.

The cutting insert according to the present embodiment is capable of setting the position of the roller dice 2 in the radial direction (the vertical direction perpendicular to the axial direction of the rotary shaft 4) by the pressing bolts 32a and 32b as the second positioning means, And the housing 5 is pressed and pulled by the tension bolt 33. [ As described above, the cutting insert of the present invention can set the position of the roller dice 2 in the radial direction by pressing and pulling the housing 5, so that the positioning of the roller dice 2 in the radial direction can be performed without depending on the tightening torque of the rotary shaft 4 It is easy to execute.

Finally, with respect to the time required for the disassembly, the conventional inserting apparatus required about 5 to 7 minutes, whereas the inserting apparatus was about 3 to 5 minutes.

The cutting device achieved a reduction of about two minutes even at the time required for disassembly. This is for the following reasons. The positioning range of the housing 5 in the radial direction of the roller dice 2 is set to be shorter than the rotational range of the rotary shaft 4 Or more. By thus securing the movable range of the housing 5 to be equal to or larger than the diameter of the rotary shaft 4, the rotary shaft 4 mounted with the roller dice 2 without detaching the housing 5 from the frame 3 It can be separated from the housing 5. This is also because the housing 5 can be separated from the frame body 3 without disassembling the frame body 3 as well.

Finally, in the main cutting device and the conventional cutting device, there is no difference in the time required for the adjustment itself. However, since the cutting device is easier to adjust than a conventional cutting device, the cutting device can not be bent or pinched by the strength of the tightening torque caused by the difference in function of the worker, It is possible to solve the problem of deteriorating the quality.

That is, since the cutting insert has a configuration in which the rotary shaft 4 is held by the housing 5 as a separate body from the frame body 3, it is required to have skill in assembly, adjustment and disassembly I have succeeded in significantly reducing the part that I do. In addition to this, the first positioning means and the second positioning means can realize a structure that can be easily assembled and adjusted in a short time without requiring particularly skilled functions.

Since the frame body 3 has the notches 10a and 10b at positions corresponding to the supply port 21 and the discharge port 22 provided at both ends of the rotating shaft 4, It was possible to move the supply port 21 and the discharge port 22 within the notches 10a and 10b without interference with the frame body 3 when positioning the frame body 3 relative to the frame body 3.

2A, the supply port (connector) 21 is provided at the right end of the rotary shaft 4 mounted on the upper housing 5, and the supply port (connector) (Connector) 22 is provided at the end of the rotary shaft 4 mounted on the lower housing 5 and a discharge port (connector) 22 is provided at the right end of the rotary shaft 4 mounted on the lower housing 5, ) 21 are provided. The supply port 21 of the upper rotary shaft 4 and the discharge port 22 of the lower rotary shaft 4 are directly connected to the flow channel of the cooling medium passing through the notches 10a on the right side of the frame body 3, Connected. By connecting the upper and lower rotary shafts 4 and 4 through the flow pipe as described above, the cooling medium is supplied to the supply port 21 of the lower rotary shaft 4 through the left cutout portion 10b, The cooling medium flowing from the lower rotary shaft 4 to the upper rotary shaft 4 is discharged from the discharge port 22 of the upper rotary shaft 4 through the left cutout 10b Could.

The frame body 3 has the notches 10a and 10b to facilitate the movement of the feed port 21 and the ejection port 22 as well as the feed port 21 and the ejection port 22. [ The flow tube of the cooling medium connected to the frame body 3 does not interfere with the frame body 3 so that the main cutting edge apparatus is simplified while realizing a high cooling efficiency of directly cooling the rotary shaft 4 for holding the roller dice 2 And a structure that can be assembled and adjusted in a short time has been realized.

It should be borne in mind, however, that the presently disclosed embodiments are in all respects illustrative and not restrictive. Particularly, in the presently disclosed embodiments, matters that are not explicitly disclosed, for example, operating conditions, measurement conditions, various parameters, dimensions, weight, volume, and the like of the components, But a value that can be easily assumed is adopted by a person of ordinary skill in the art.

For example, in the first positioning means and the second positioning means, a force for pressing or pulling the housing 5 is applied by using a bolt passing through the frame body 3. However, if a member or a mechanism capable of applying the same force, the first positioning means and the second positioning means may be constituted by members other than the bolt.
