The part is to close and open the air discharge hole 202 formed in the rear side of the cylinder 200. That is, when the air supply hole 201 is opened, the air discharge hole 202 is closed, and when the air supply hole 201 is closed, the air discharge hole 202 is opened.

The operation of the valve body 220 is controlled by the flow of compressed air. When the compressed air is supplied by connecting an air pressure hose to the air supply port 110, the valve body 220 opens the air supply hole 201. By supplying compressed air to the side of the cylinder 200 to the piston 210 is located in the front of the cylinder (200). And by placing the tableting nail inside the tableting nail guide 124 of the tableting unit 120, when the user presses the tableting body against the tableting object by applying an external force, the piston rod 210 is moved backwards. Is moved backwards. At this time, the O-ring 213a formed in front of the piston 210 closes the air supply hole 201, and the air supply hole 201 is blocked, so that the compressed air has an air discharge hole 202 having a low pressure. Pressure is concentrated toward the valve body 220 on the side to move the valve body 220 to the front side to close the air supply hole 201 and simultaneously open the air discharge hole 202 to compress the rear of the piston 210. By supplying air, the piston 210 is flowed forward by the compressed air supplied instantaneously, the piston rod 211 tableting the tableting nail is a tableting operation is made. When the piston 210 is moved forward, the O-ring 213a formed at the front side of the piston 210 opens the air supply hole 201, and the compressed air discharged to the rear of the piston 210 cylinder 200. ) And the compressed air is supplied to the front of the valve body 220 through the air supply hole 201 to reverse the space between the piston 210 and the piston 210 to move the valve body 220 backward.

The protruding rod 141 prevents the compressed air from being discharged in a short time, thereby providing a pressure for allowing the compressed air to flow in the valve body 220. In addition, an external discharge hole (not shown) is formed at one rear side, and compressed air discharged through a predetermined space between the air discharge port 231 and the protruding bar 141 is discharged to the outside. In addition, a valve packing 142 is formed at a portion where the valve body 220 abuts to prevent the compressed air from being minutely discharged when the valve body 220 closes the air discharge hole 202.

With reference to the drawings showing the operation of the portable air tablet press according to the present invention having the configuration as described above.

3 is a working view of a portable air tablet press according to the present invention. As shown, the tableting nail is inserted into the tableting nail guide 124 formed at the tip of the tableting unit 120. At this time, the tableting nail is prevented from being separated by the magnet 128 formed on one side of the tableting nail guide 124, and it is possible to stably tablet. Then, when the tableting nail guide 124 close to the tableting object and an external force is applied, the tableting nail guide 124 is pushed backward and the tableting nail head contacts the end of the piston rod 211 so that the piston 210 is rearward. Is moved. At this time, the O-ring 213 formed in front of the piston 210 closes the air supply hole 201, and the air supply hole 201 is blocked, so that the compressed air has an air discharge hole 202 having a low pressure. Pressure is concentrated toward the valve body 220 on the side to move the valve body 220 to the front side to close the air supply hole 201 and simultaneously open the air discharge hole 202 to compress the rear of the piston 210. By supplying air, the piston 210 is flowed forward by the compressed air supplied instantaneously, the piston rod 211 tableting the tableting nail is a tableting operation is made. When the piston 210 is moved forward, the O-ring 213 formed at the front side of the piston 210 opens the air supply hole 201, and the compressed air discharged to the rear of the piston 210 cylinder 200. ) And the compressed air is supplied to the front of the valve body 220 through the air supply hole 201 to reverse the space between the piston 210 and the piston 210 to move the valve body 220 backward. By opening the air supply hole 201, and closes the air discharge hole (202).

In addition, since the flow distance of the piston 210 is short, the tableting is not completely completed in one process, and thus, when the external force is continuously applied, the above process is repeatedly performed, and the tableting nail is completely compressed into the tableting object.

When the tableting operation is completed through such a process and releases the external force, the tableting nail guide 124 is moved forward again by the elastic force of the spring 123 to return to the initial state.

In addition, if a tableting nail is inadequately compressed after tableting with an air tableting machine, the tableting nail guide 124 of the portable air tableting machine is applied to the head of the tableting nail by applying an external force to the tableting nail. Is completely compressed to.

As described above, the portable air tableting machine according to the present invention is different from the case of using an air tableting machine for continuously tableting nails. This can reduce the waste of manpower.

In addition, there is an advantage that can complete the tableting work by taping the tableting nails with a single shot at the end of the tableting work and the uncompressed tablets when the tableting nails are inadequate after the tableting work.

In addition, when the magnet is installed at the tip of the other government and the tableting nail is inserted into the tableting object, the tableting nail is prevented from being detached and thus the tableting operation can be easily performed.
