Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a receiving plate for a cutting blade used when cutting an elastomer such as rubber or synthetic rubber.

[Prior Art] Conventionally, when an elastomer such as rubber or synthetic rubber is used as a material for electric parts and a right angle of a cut surface is required, the elastomer set on the upper side of the pedestal of the cutting device is pushed from the upper side. A method of cutting with only the descending cutting blade is adopted.

That is, as shown in FIG. 2, for the cut surface 2 of the plate-shaped rubber 1 as an electric component material, the corners 2a, 2b of the upper and lower surfaces of the cut surface 2 are cut at right angles in order to obtain the required component characteristics. Required to be present.

Due to this requirement, as the cutting device, the device shown in FIG. 3 is used. That is, in the cutting device shown in FIGS. 3A and 3B, the press itself has a normal structure, and the frame 3 has wheels 4 as a portable type in the illustrated example. An upper frame 5 is movably supported on the upper portion of the frame 3 via a guide post 6, and a hydraulic cylinder 7 is mounted on the frame 3, and the upper frame 5 is vertically moved by the hydraulic cylinder 7. Is configured to be able to. Further, a cutting blade 8 is attached to the upper frame 5.

A base 9 is provided below the frame 31 so as to face the cutting blade 8 attached to the upper frame 5, and a receiving plate 10 is detachably provided on the upper side of the base 9.

When the plate-shaped rubber 1 is cut into a desired shape with the cutting device having such a configuration, the upper frame 5 is moved upward through the hydraulic cylinder 7 and the cutting blade 8 is raised. After placing the plate-shaped rubber 1 on the lower side of the receiving plate 10 of the base 9 and placing and setting it, the hydraulic cylinder 7 is driven to move the upper frame 5 to the guide post 6
The cutting blade 8 cuts off the cut portion of the plate-shaped rubber 1 placed and set on the upper side of the receiving plate 10.

[Problems to be Solved by the Invention] The plate-shaped rubber 1 is cut by the descending operation of the cutting blade 8. At this time, the cutting edge of the cutting blade 8 is received by the receiving plate 10 above the base 9 and In order to prevent damage, in particular, the receiving plate 10 is formed of a material such as hard urethane rubber, and the cutting blade 8 is repeatedly cut, so that the contact position of the receiving plate 10 itself with the cutting blade 8 is damaged. Cutting blade 8 to receive
Depending on the number of cuttings of the
It is used while displacing the arrangement position of the 10 above the base 9
When the effectiveness of the cutting blade 8 as a receiving part at the time of cutting is lost, the cutting operation of the plate-shaped rubber 1 is performed by replacing it with a new receiving plate 10, so to speak, a receiving plate made of the hard urethane rubber material. 10 was used as a consumable item.

Therefore, depending on the conventional cutting device, a work for changing the position of the backing plate 10 is required during the cutting work, and a new backing plate 10 is required.
There was a defect that the replacement work to replace with was required.

Therefore, the present invention has been devised in view of the above-mentioned drawbacks of the cutting device, and is designed to receive a cutting blade in a cutting device for an elastomer such as rubber or synthetic rubber which does not require a position changing operation or a replacement operation during the cutting operation. The purpose is to provide a board.

[Means for Solving Problems] The receiving plate of the cutting blade for elastomer of the present invention comprises a pressure-receiving sheet layer of the cutting blade made of a metal material such as an iron material, and a cushion material such as rubber on the lower surface of the pressure-receiving sheet layer. It consists of

[Operation] In the receiving plate of the cutting blade for elastomer of the present invention, the direct contact surface with the cutting blade is received by the pressure receiving sheet layer, and the pressure at the time of cutting the elastomer of the cutting blade is buffered by the pressure buffer layer. is there.

[Embodiment] An embodiment of the receiving plate of the present invention will be described below with reference to the drawings.

FIG. 1 is a partially enlarged sectional view showing an embodiment of the receiving plate of the present invention.

In the figure, 20 is a receiving plate, and this receiving plate 20 is composed of an upper pressure receiving sheet layer 21 and a lower pressure buffer layer 22.

The upper pressure-receiving sheet layer 21 is a sheet (for example, 0.2 mm) made of a hardened and hardened iron material, and the lower pressure buffer layer 22 is a rubber or synthetic rubber sheet (for example, 2 mm).
It is formed by adhering a sheet of rubber or a hardened and hardened iron material on the upper side of the synthetic sheet.

Further, due to the nature of the receiving plate 20 having such a configuration, in the pressure receiving sheet layer 21, the cutting edge of the cutting blade directly abuts when cutting the elastomer such as rubber or synthetic rubber by the cutting blade, and is damaged by this. This is a metal material that can be reduced as much as possible, and is formed with a thickness that can prevent damage to the cutting edge of the cutting blade in combination with the cushioning action of the pressure cushioning layer 22.

In addition, for the pressure buffer layer 22, a cushioning material capable of absorbing an applied pressure to the pressure receiving sheet layer 21 at the time of cutting by the cutting blade and obtaining an action capable of preventing damage to the cutting blade directly contacting the pressure receiving sheet layer 21. However, the structure is not limited to the above-mentioned embodiment.

Further, when a rubber or synthetic rubber sheet or the like is used in forming the pressure buffer layer 22, the same sheet is formed by including a powder made of a magnetic material in a molding material such as the rubber or the synthetic rubber sheet, When the pressure buffer layer 22 is formed of such a sheet, it is positioned at a position facing the cutting blade of the cutting device, and when the backing plate 20 is fixed to the upper side of the base 9, the magnetic substance of the pressure buffer layer 22 is removed. Receiving plate due to magnetized magnetic force
The advantage of being able to fix 20 is obtained.

When the elastomer such as rubber or synthetic rubber is cut by the cutting device shown in FIG. 3 using the receiving plate 20 of the present invention having the above structure, the cutting position of the cutting blade 8 corresponds to the upper side of the base plate 9. After mounting and fixing the receiving plate 20 at least, the hydraulic cylinder 7 is driven to cut by the cutting blade 8 while the elastomer such as rubber or synthetic rubber is loaded and set on the base 9 on which the receiving plate 20 is set. To do.

The cutting edge of the cutting blade 8 at the time of cutting the elastomer comes into contact with the receiving plate 20 after cutting the elastomer, but the impact force of the cutting blade 8 is absorbed by the structure of the pressure receiving sheet layer 21 and the pressure buffer layer 22, and The cutting edge 8 is not damaged by the pressure-receiving sheet layer 21 and the receiving plate 20 is not damaged by the cutting blade 8, and the elastomer can be accurately cut at the cutting surface 2 at a required angle. It was confirmed that the position of the contact position of the cutting plate 8 with the cutting blade 8 corresponding to the repeated cutting work by the cutting blade 8 was changed, and the frequency of the conventional receiving plate 10 made only of hard urethane rubber or the like. It was possible to perform cutting work without the need for expensive replacement work.

[Advantages of the Invention] According to the receiving plate of the cutting blade for elastomer of the present invention, the pressure buffer layer magnetically adsorbs the pressure receiving sheet layer and absorbs the pressing force at the time of cutting of the cutting blade. It is possible to perform the cutting work of elastomer such as rubber or synthetic rubber without the need for replacement work or replacement work, which can improve the workability of the cutting work and extend the service life of the conventional backing plate as a consumable item, which is economical. It is possible to improve the property.
