Abstract

(57) [Abstract] [Purpose] The present invention not only makes it possible to significantly increase the life of the cutting blade itself by effectively utilizing the entire circumference of the cutting blade 4 and reduce the deburring cost, but also to simplify the operation. It provides a deburring tool that can be manufactured. [Structure] A pair of circular cutting blades 4 is detachably installed side by side through a holder 5 on a required fixture 2 or 14, and a plate to be cut is provided between the pair of circular cutting blades 4 installed side by side. Burrs are removed by applying both corner edges of A and sliding while pressing the outer peripheral edges of the circular cutting blades 4 along the both corner edges. When the cutting portion of the circular cutting blade 4 is worn or damaged, the circular cutting blade 4 is rotated in a predetermined direction to sequentially change to a new cutting portion for deburring.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a deburring tool capable of cutting and removing burrs generated at a cutting edge when a stainless plate, a steel plate, a plastic plate or the like is cut and processed.

[0002]

[Prior art]

 The burrs that occur on the cutting edges of stainless steel plates when they are cut and processed are sharp, and they are very dangerous because they can easily damage human hands during handling, and they are very unsightly in appearance. For this reason, it has been conventionally said that such burrs are ground and removed by a sand paper or grinder when cutting a stainless steel plate or the like, but the work efficiency is very poor and the unevenness is caused. Not only is it easy to cause burrs, but it is difficult to deal with the removal of unground burrs after bending stainless steel plates or after assembling them into the required equipment, or burrs that have not been sufficiently ground.

For this reason, conventionally, a deburring tool has been proposed in which an inverted V-shaped cutting blade is attached to the tip of a rod provided with a handle (Japanese Utility Model Publication No. 55-70926, Japanese Utility Model Publication No. 55-70926). (See Sho 59-69821). Such a deburring tool is a tool for gripping a handle, applying cutting blades to both edges of a plate to be cut, and sliding along the edges while pressing them to remove burrs.

[0004]

[Problems to be solved by the device]

 The above-mentioned conventional products can perform deburring very favorably by sliding the inverted V-shaped cutting blades along both corners of the work piece while gripping the handle, while deburring. Since the cutting parts of the cutting blade in the above are always concentrated on a certain part, the part is very likely to be worn or damaged, and the life of the cutting blade is extremely short, and a new cutting blade must be replaced each time. , As a whole, it caused an increase in deburring cost. Further, since the cutting blade itself is formed in an inverted V shape, it has been considered to be troublesome and time-consuming to manufacture.

This invention intends to solve the conventional problems all at once, and makes it possible to effectively utilize the entire circumference of the cutting blade to significantly extend the life of the cutting blade itself and reduce the deburring cost. Not only is it possible to provide a practical tool for deburring that can be easily manufactured.

[0006]

[Means for Solving the Problems]

 That is, this invention has a structure in which a pair of circular cutting blades 4 are removably arranged side by side through a holder 5 on required fixtures 2 and 14.

[0007]

[Action]

 Burrs are removed by applying both edges of the plate A to be cut between a pair of circular cutting blades 4 arranged in parallel and sliding while pressing the outer peripheral edges of the circular cutting edges 4 along the both edges. Excuse me. When the cutting portion of the circular cutting blade 4 is worn or damaged, the circular cutting blade 4 is rotated in a predetermined direction to sequentially change to a new cutting portion for deburring.

[0008]

【Example】

 An embodiment of the deburring tool 1 according to the present invention shown in the drawings will be described below. Reference numeral 2 denotes a bifurcated plate-like fixture whose tip portion is bent at a predetermined angle, 3 is a contact plate installed at the tip of the fixture 2, and 4 is a holder on the corresponding plate 3, respectively. Circular cutting blades are removably provided side by side through the circular cutting blades 5. The circular cutting blades 4 are formed by cutting the outer peripheral edge of a substantially disc body into a substantially taper shape. Reference numeral 6 denotes a mounting bolt for integrally screwing each holder 5 and the circular cutting blade 4 through the bolt insertion holes 7 and 8 formed in the fixture 2 and the contact plate 3, respectively. In addition, A indicates a plate to be cut such as a stainless plate or a steel plate.

The deburring tool 1 configured as described above is, for example, a deburring device 9 shown in FIGS. 3 and 4, that is, a pair of front and rear feed rollers horizontally arranged on a rectangular frame 10. Install the racks 11 and 12 facing each other with a predetermined gap. Then, while the required plate A to be cut supported on the pedestal 13 is sequentially fed forward by the feed rollers 11 and 12, both side edges thereof are pressed against the corresponding pair of circular cutting blades 4. By sliding it, the burr is removed by cutting. At this time, when the cutting portion of the circular cutting blade 4 is worn or damaged by long-term use, the mounting bolt 6 is loosened and the circular cutting blade 4 is moved slightly in the predetermined direction to move to a new cutting portion. I hope you can change it.

The deburring tool 1 according to the present invention is used by being attached to the deburring device 9 as described above, and as shown in FIG. 6 and FIG. It may be attached to a required handle 15 and manually deburred.

[0011]

[Effect of device]

 According to the present invention, the pair of circular cutting blades 4 is detachably arranged in parallel to the required fixtures 2 and 14 via the holder 5 according to the above. Burrs can be surely removed by placing both edges of the plate A to be cut between the four and sliding the outer edges of the circular cutting blades 4 along the both edges while pressing them. Especially, since the cutting blade 4 according to the present invention has a circular shape, when the cutting portion of the circular cutting blade 4 is worn or damaged, the circular cutting blade 4 should be rotationally moved in a predetermined direction. It is possible to change to a new cutting site and use it for deburring, and the entire circumference of the circular cutting blade 4 can be effectively used as a cutting blade one after another. The life of 4 can be remarkably increased and the deburring cost can be reduced. In addition, since the pair of circular cutting blades 4 are juxtaposed to the required fixtures 2 and 14 with the holder 5 interposed therebetween, the manufacturing thereof is extremely easy and inexpensive. Can be provided.
