Abstract

PROBLEM TO BE SOLVED: To eliminate burrs produced in a hole line with a medium provided for eliminating burrs so as to have play in a hole formed in a material to be processed. SOLUTION: A processed material 1 having a ball body 3 fitted in a hole 9 is transferred between a medium driving device 5 and a separation part 12 on a conveyor 2, blown out from an air jetting-out nozzle 13 and brought into contact with air flowing through the opening of an interval maintaining member 4. At this time, the ball body 3 is moved in the hole 9 and clashes with the wall surface of the hole 9, particularly its corner edgeline part, or another ball body 3 inside the hole 9, but since the interval maintaining member 4 exists in a direction opposite the conveyor 2, the ball body 3 clashes with this member and thus its jumping out from the hole 9 is prevented. By clashing between the wall surface of the hole 9, particularly its corner ridgeline part, and the ball body 3, burrs are detached, ground and then eliminated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deburring apparatus and method for removing burrs generated when a material such as a metal plate is subjected to processing such as hole formation by machining or pressing. More specifically, the present invention relates to a deburring device and method for removing burrs formed on a metal plate or the like (hereinafter, referred to as a material to be processed in the present specification) punched by a turret puncher or the like to make holes.

[0002]

2. Description of the Related Art Generally, burrs are formed at corners of a machined or pressed part. If parts are processed and assembled without removing burrs generated in these processing steps, accurate assembly cannot be performed. Also, even when assembled into a machine, the burrs fall off and fall into the details of the machine, lowering the operation reliability of the machine or, in the case of a machine installed in a clean room, generating dust around the machine. It is discharged and has a bad influence on the surrounding environment. Further, if a part of the body such as a hand touches the portion where the burr is attached, "injury" may occur, which is dangerous. Especially in today's era of product liability, this should be avoided as much as possible.

[0003] By the way, conventionally, studies have been made to remove burrs by cutting or grinding, but mainly hydraulic pressure,
Valves and pipes of pneumatic equipment are made for relatively rigid parts as a whole, but there is not much solution for punching a plate with low rigidity as this part. A grinding wheel method and a grinding belt method for removing are mainly used.

[0004]

However, the conventional methods using the grinding wheel method and the grinding wheel belt method have the following problems. That is, since the surface of the material to be processed is removed together, the plate thickness dimension of the material to be processed is reduced by the deburring process. Further, in the case where the surface-treated material is punched out with a turret puncher or the like, the conventional method cannot be applied because the surface-treated layer is damaged. For that reason, I have no choice but to rely on manual work. And other issues.

As a result of various studies on deburring of a material to be processed, the present inventor used a spherical or three-dimensional medium for deburring without removing the surface of the material to be processed, which was not possible by the conventional method. By finding that it is possible to remove unstable burrs in the punched portion and round the corner ridges by filling the punched portion with rocking motion or vibration to the medium. I arrived.

[0006] Therefore, based on such knowledge, the present inventor made various prototypes of deburring devices for punched material to be processed, evaluated the performance, and evaluated the material of the plate material, the plate thickness, and the medium used for deburring. By selecting the shape, size, and material, it was clarified that deburring can be performed automatically without scratching the surface of the material to be processed.

Further, according to the deburring device of claim 8, since the medium driving device has a driving mechanism for swinging the medium housing frame member for housing the medium in the front-back direction and / or the left-right direction, the medium is smoothly covered. It has an effect that it can be moved in the hole of the processing material or in the hole formed by the frame material and the processing material. According to the deburring device of claim 9, since the radius of the medium is a sphere having a thickness equal to or larger than the thickness of the material to be processed, the medium can be reliably collided with the burr at the corner ridge of the material to be processed. The effect is that burr can be removed efficiently.

According to the deburring device of the tenth aspect, since the support for the material to be processed can convey the material to be processed, it becomes possible to continuously process a large number of materials to be processed. It has an effect that productivity can be improved. According to the deburring device of claim 11, since the straightening device is provided in front of or behind the deburring by the floating medium, the shape of the material to be processed is distorted and the deburring effect by the floating medium is improved. It is also possible to remove large burrs that remain even after deburring with a floating medium, and the effect of deburring can be improved. According to the deburring device of claim 12, since the device for supporting the material to be processed is a conveyor, and the conveyor has convex portions at predetermined intervals for supporting the material to be processed in a floating state. It has an effect that the medium can be effectively contacted with the edge portion of the hole to be processed on the bottom side. According to the deburring device of claim 13, the medium storage frame member is replaceable,
Further, since the frame material is formed with a hole at the same position as the material to be processed, the medium surely falls into the hole, floats in the hole, and does not damage the surface of the material to be processed. It has the effect that it can be taken accurately.

The air ejection nozzles 13 are arranged in a staggered manner in the figure, and the air flow ejected from the air ejection nozzles 13 actively moves the spheres 3. This air jet nozzle 13 is a sphere 3
Any arrangement may be used as long as it can actively move the animals. Here, if the air ejection nozzle 13 is allowed to perform a swinging motion, the sphere 3 will move more freely. The air ejected from the air ejection nozzle 13 penetrates through the opening of the distance maintaining member 4, collides with the sphere 3, and floats and rotates on the sphere 3 in the hole 9 between the distance maintaining member 4 and the conveyor 2. By vibrating or the like, the small holes 22 of the conveyor 2 are passed through and the sheets are discharged to the outside of the apparatus.

The air, which is transferred between the two, blows out from the air ejection nozzle 13 and penetrates the opening of the distance maintaining member 4. At this time, the sphere 3 floats in the hole 9 such as turning, vibrating, oscillating, and floating, and collides with the wall surface of the hole 9, in particular, a corner ridge or another sphere 3 in the hole 9. Since the space maintaining member 4 is provided in the direction opposite to the space 2, the space maintaining member 4 does not collide with the space maintaining member 4 and jump out from the hole 9. The burr is detached by the collision between the wall surface of the hole 9, particularly the corner ridge and the sphere 3, and the burr is removed by polishing.

The material 1 to be processed, which has been transferred between the medium driving device 5 and the separating section 12 and has reached the end of the conveyor 2, is subsequently transferred to a transfer roll 16 and, if necessary, carried to a straightening roll 7. With this straightening roll 7, large burrs of the material 1 to be processed are bent and crushed, and separated and removed to obtain a product.

The spheres 3 in the holes 9 of the material 1 to be processed are blown out of the holes 9 by the air jetted from the separation nozzle 14 at the end of the conveyor 2, collected in the medium receiving section 15, and separated in the separation section 12.

The present invention is not limited to the above-described embodiments, but includes configurations that can be modified within the scope of the present invention. Incidentally, in the above-described embodiment, while continuously moving the conveyor, instead of the configuration in which air is ejected from the fluid ejection nozzle to float the medium to remove burrs, the conveyor is intermittently moved and then stopped. The air may be jetted from the fluid jet nozzle to float the medium to remove burrs, or the material to be treated is placed on a swingable table and the sphere is fitted into the hole. After that, the table may be surrounded and the table may be swung. In addition, although the example in which the space maintaining member is provided entirely between the fluid ejection nozzle and the conveyor is shown, when the medium is large and it is difficult to float, it is provided only at the starting end and used only for distributing the medium. It may be configured. Other than the above, the structure is not limited to the above example, and it is needless to say that the structure may have the same effect.

Further, the deburring apparatus of the present invention can be applied to deburring of the outer peripheral edge of the material to be processed, as well as deburring of the peripheral edge of the hole which has been drilled in the material to be processed. In this case, a frame material is arranged around the material to be processed, and a medium such as a sphere is distributed and supplied into a hole formed between the frame material and the material to be processed to allow the medium to float. The configuration. Other configurations are similar to those of the above-described embodiment.
