Description

Air punching machine intergrated in nail guide

The present invention relates to a pneumatic tableting machine, and more specifically, to form a nail tablet piece integrally with the body, and to change the structure of the safety guide piece to prevent the bad work of the tableting nail and to improve the productivity of the nail tablet piece integrally air It is about a tablet press.

In general, in connection with various products made of wood, for example, furniture or buildings, such as nails or staples, the work was performed using a manual tool such as a hammer. However, the work using the manual tool, although the work speed varies depending on the skill of the operator, there is a problem that the work speed is not very slow, and the tableting nail or staples are not uniformly compressed.

Therefore, in recent years, a large number of pneumatic tablet presses can be used to simply nail nails or staples to wood using air pressure. Such a pneumatic crusher is inserted into the continuous nail holder material that is continuously connected staples or nails, and when the trigger is pulled against the object to be fixed, the loaded continuous nail is guided by nail nail pieces to be nailed to the object one by one . These pneumatic presses are usually made in one piece, and thus have a problem of causing a considerable economic burden on the user because the whole should be replaced even when some parts fail.

In order to solve the above problems, the air-pressing machine which is disassembled and assembled for each part was applied to the Republic of Korea Utility Model Application (Application No. 92-435) in 1992 to allow replacement of only some parts. Since the air crusher currently on the market is usually composed of a disassembled structure for each of these parts, the following will be described with reference to the drawings showing the air assembler disassembled for each of these parts.

1 is an exploded perspective view of a conventional pneumatic tablet press, Figure 2 is an exploded perspective view of a nail guide piece. As shown in the figure, the hollow handle portion 10 and the pneumatic squeeze portion 20 are formed in a state in which the body is integrally formed. In addition, a trigger 11 is provided at one side of the front upper surface of the handle part 10, and an air pressure hose is connected to the bottom surface thereof, and a coupling piece 12 is provided at the rear side thereof to which the continuous nail holder 50 is coupled. . On the other hand, a protruding bracket 21 is integrally formed with the pneumatic squeezing unit 20 on the front lower side of the pneumatic squeezing unit 20, and the nail fixing piece 30 and the safety guide piece 40 on the bracket 21. ) Is combined. Then, the continuous nail holder 60 is equipped with a continuous nail is connected through the bottom surface of the nail tablet piece (30).

With reference to Figure 2 showing the coupling and the structure of the nail piercing piece 30 and the safety guide piece 40 will be described in more detail. A bracket 21 protruding from the front lower side of the pneumatic screwer 20 is formed. The bracket 21 forms a semicircular groove so that a space is formed around the tableting pin 22, and bolt holes a are formed at both sides thereof. As for the nail tablet piece 30, the bolt hole b corresponding to the said bolt hole is formed in the back, and the nail guide groove 31 penetrates in the longitudinal direction in the center part. In addition, the nail guide groove 31 and the one side spaced apart a predetermined interval is formed with a guide groove 32 through which the guide piece 50b of the safety guide piece 40 to be described later, the guide groove 32 of the On the side is formed a holder bolt hole (c) for fixing the continuous nail holder 60 is coupled to the bottom of the nail tablet piece (30).

On the other hand, the safety guide piece 40, a bolt fastening hole (d) corresponding to the bolt hole (a) of the bracket (1) and the bolt hole (b) of the nail tablet piece (30) is formed at the rear, the handle Guide ribs (50b) connected to the trigger of the negative portion is formed on the side and is made of a guide piece (50a) that serves as a safety device for triggering as it moves in the front and rear directions. Side portion of the guide piece (50a) is made of a structure connected to the guide rib (50a) through the guide groove 32 of the nail guide piece (30).

Briefly describing the operation process of the air tableting machine under the above structure, the parts are assembled and pressed in close contact with the tip of the nail tablet piece 30 to the position to nail using the completed air tableting machine. At this time, as the safety guide piece 50b is pushed backward, the guide rib 50a connected to the guide piece 50b releases the lock of the trigger 11. When the trigger 11 is pulled from the lock release, the tableting pin 22 located inside the pneumatic squeezing unit is triggered by the high pressure air transmitted through the air pressure hose. The tableting pin 22 impacts one nail located in the nail guide groove 31 of the nail tablet piece 30 among the continuous nails mounted through the continuous nail holder 60, and thus nails are triggered. It gets stuck in the target wood.

The air tableting machine having the structure as described above has an advantage that it is easy to replace each part due to disassembly and assembly, but has the following problems.

First, a significant high pressure is applied during the operation of the air tabletting machine, and thus, the nail tablet piece 30 and the safety guide piece 40 which are in contact with the object by the high pressure transmitted through the tip portion of the pneumatic squeezing unit 20. The shock is transmitted, and the bolt 41 fastened by the shock is easily released so that a small failure and accurate tableting are not made. In other words, the impact applied to the nail pinning piece 30, the safety guide piece 40 is transmitted to the bolt 41 is fastened through the bracket 21. Accordingly, the bolt 41 is loosened, and the bolt loosening causes the nail nail piece 30 to be twisted so that the nail supplied through the continuous nail holder 60 cannot be accurately mounted in the nail guide groove 31. Not only does it cause a failure, there is a problem that makes the continuous nail holder 60 or nail nail piece 30 can not be used. In the integrated tablet press, the defect of the continuous nail holder is most frequently generated, and thus, an alternative decomposable air tableter has been developed. However, the decomposable air tablet press has more than the continuous nail holder 60. Not only malfunction, but also bad tablets.

The guide piece 50b of the safety guide piece 40 is coupled to the guide rib 50a0 through the guide groove 32 of the nail fixing piece 30 to be connected to the trigger 11 to disassemble and assemble. In addition to the difficult work, there is a problem in that the mold forming and manufacturing work of such a member is difficult, thereby increasing the manufacturing cost of the air filter press.

Therefore, the present invention is to solve the above problems, the pine nut is a continuous nail holder, which is a failure part is made by disassembly combination to enable partial replacement, and the pneumatic tableting machine to prevent the failure of the bad tableting and nail tablet pieces due to the impact It aims to provide.

In addition, the present invention improves the disassembly and assembly of the air filter press by changing the coupling structure of the guide ribs, and provides an air tablet press that can improve the production efficiency and reduce the manufacturing cost by simplifying the production of the air filter press. For other purposes.

As shown, the air tableting machine according to the present invention, largely composed of the tableting base 100, the continuous nail holder 60 and the safety guide piece (140).

First, the tableting base 100 will be described. The tableting main body 100 according to the present invention is integrally formed with the handle portion 10, the pneumatic squeezing unit 20, and the nail guide piece 130. The lower one side of the handle portion 10 is provided with a protruding coupling piece, coupled to one side of the continuous nail holder 60 to be described later through the bolt hole of the coupling piece to support the continuous nail holder 60. Since the handle portion 60 has the same structure as the prior art, a detailed description thereof will be omitted.

In addition, a pneumatic tableting unit 20 is positioned in front of the tableting base 100, and a tableting pin which is operated by air pressure is provided in the pneumatic tableting unit 20. Then, the nail guide piece 130 is formed integrally with the front lower side of the pneumatic rudder 20. A protruding rib 132 is formed on the rear side of the nail guide piece 130, and a through groove is formed in the protruding rib 132. The safety guide piece 140 to be described later is coupled to the protrusion rib 132 is rotated up and down. Then, the nail guide groove 131 is formed in the longitudinal direction through the central portion of the nail guide piece 130, the nail guide groove 131 is made of a concave-convex structure to accommodate the nail having a variety of lengths. have. On the other hand, both sides of the nail guide piece 130 is formed through the bolt hole (a) penetrated up and down is continuous nail holder 60 to be described later is coupled through the bolt hole (a) is coupled. In addition, the nail guide piece 130 formed integrally with the tableting base 100 is formed to have a somewhat thicker thickness than in the related art. Therefore, it is possible to better withstand the strong shock caused by the air pressure.

Next, the continuous nail holder 60 will be described. The continuous nail holder 60 is provided with a spring member (not shown) in the inner lower portion, the continuous nail is inserted into the upper space of the spring member so that the continuous nail is raised by the elastic force of the spring. In addition, a coupling rib 62 is formed at one lower side of the continuous nail holder 60. A bolt hole is formed at the end of the coupling rib 62 and fastened with a bolt in a state coinciding with the bolt hole of the coupling piece 12 of the handle part 10. In addition, a bolt hole corresponding to the bolt hole of the nail guide piece 60 is formed on the upper surface of the continuous nail holder 60, and a holder groove 61 is formed to supply the continuous nail in the longitudinal direction of the center part. have. Therefore, the holder groove 61 is located on the bottom surface of the nail guide groove 131 in the state where the bolt hole of the continuous nail holder 60 and the bolt hole of the nail guide piece 130 coincide with each other. The continuous nail supplied through the nail guide groove 131 can be seated.

On the other hand, in the present invention, the safety guide piece 140 is located on the upper surface of the nail guide piece 130. The structure of the safety guide piece 140 will be described. At the rear end of the safety guide piece 140, a protruding piece 142 having an empty central portion is formed. A through groove is formed in the center portion of the protruding piece 142. Accordingly, the protruding ribs 132 and the protruding ribs 142 of the nail guide piece 130 are inserted into the central portion so that the protruding ribs 132 are positioned at both sides of the protruding pieces 142. The pin 143 is inserted through the through grooves of 132. As a result, the safety guide piece 9140 is coupled to the nail guide piece 130, and at the same time, the pin 143 can be rotated in the upward direction using the pin 143 as the pivot center axis. As described above, the upper portion of the safety guide piece can be rotated, so that the foreign matter removal and the defective nail of the nail guide groove 131 can be removed without completely disassembling the safety guide piece 140.

In addition, the guide ribs 150 are formed on the safety guide piece 140. The guide rib 150 is connected to the trigger to release the locking device when tableting, unlike the prior art is connected to the trigger through the outside of the nail guide piece (130). Therefore, in the present invention, since the nail guide piece 130 does not have to be provided with a separate guide groove conventionally formed, the nail guide piece 130 may be more easily manufactured.

When explaining the structure of the guide rib 150 in more detail, the tip 151 of the '∩' shape protruding a little more forward than the tip of the nail guide piece 130, and at one end of the tip 151 A contact pin 152 extending horizontally by a predetermined length is coupled to the guide rib body 154. The guide rib body 154 is positioned outside one side of the safety guide piece 140, extends a predetermined length in the lower vertical direction, and then extends horizontally again to be connected to the trigger. On the other hand, the spring 156 is embedded through the rear side of the guide rib body 154 and one side hole 154a of the nail guide piece 130 so that the guide rib 150 is movable in the front and rear directions. Therefore, when the front end 151 of the contact pin 152 of the guide rib 150 is pressed on the target wood, the guide rib 150 is moved to the rear to release the lock of the trigger.

Next, the process of disassembly assembly and operation of the air tabletting machine according to the present invention configured as described above will be described. The handle portion 10 and the pneumatic screwer 20 and the nail guide piece 130 are integrally formed with the body 100, the continuous nail holder 60, and the safety guide piece 140, respectively. Therefore, the manufacturing labor of each component constituting the tableting machine can be reduced, and the manufacturing cost can be reduced.

As described above, the continuous nail holder 60 is coupled to the main body in the state where each component is prepared. Position the continuous nail holder 60 to the bottom of the nail guide piece 130 so that the bolt hole formed on the upper surface of the continuous nail holder 60 matches the bolt groove (a) of the nail guide piece 130, and then By fastening the continuous nail holder 60 is coupled to the nail guide piece (130). The most important part in the coupling process is whether the holder hole of the continuous nail holder 60 and the nail guide groove 131 of the nail guide piece 130. Conventionally, when fastening with bolts, the bolts are not precisely coupled in a straight line, and the direction is distorted, so that the fastening is not made frequently. However, in the present invention, as described above, since the nail guide piece 130 is formed to be somewhat thick, when the bolt is fastened, many parts of the bolt are inserted into the bolt groove (a) of the nail guide piece 130. Since it is guided, it is not twisted in the left and right directions when applying the force for fastening the bolt, so that accurate assembly is possible. As described above, in the state in which the continuous nail holder 60 is coupled to the bottom surface of the nail guide piece 130, the coupling rib formed on the lower side of the continuous nail holder 60 and the handle portion 10 of the main body 100 Tighten the bolts in the state where the pieces are matched, and connect the continuous nail holder firmly to the main body.

As described above, the safety guide piece 140 is coupled to the continuous nail holder 60 in a coupled state. Of course, the safety guide piece 140 may be coupled first before the continuous nail holder 60 is coupled. The safety guide piece 140 is a nail guide piece 130 by using the pin 143 in the state in which the protrusion piece 142 of the safety guide piece 140 and the protrusion rib 132 of the nail guide piece 130 are matched. Combine so that it rotates on the upper surface of). In the above state, the guide rib body 154 is positioned outside the nail guide piece 130, that is, through the upper portion of the continuous nail holder 60, so that the end of the guide rib 150 is connected to the locking device of the trigger. Combine. Therefore, the coupling operation of the safety guide piece 140 can be made very simple.

The tableting operation is performed using the tableting machine completed through the combination process as described above. That is, when the tip 151 of the contact pin 152 of the guide rib 150 is brought into contact with the target position, the guide rib 150 is pushed backward by the action of the spring 156 to lock the trigger. Will be released. Of course, in the above state, one of the continuous nails is positioned in the nail guide groove 131 of the nail guide piece 130 through the holder groove 61 by the spring action inside the continuous nail holder 60.

When the trigger 11 is triggered, the compression pin located inside the pneumatic squeezing unit 20 triggers the nail seated in the nail guide groove 131 forward by the applied air pressure, thereby triggering the nail at the target position. Will be. As described above, the impact caused by the trigger is applied to the nail guide piece 130, accordingly, in the conventional case where the nail guide piece 130 is bolted to the tableting base body, the twist of the bolt fastening by the impact Occurred. Therefore, the torsion of the nail guide piece did not coincide with the holder groove and the nail guide groove, causing a trigger failure and damage to the nail guide piece.

However, in the present invention, the nail guide piece 130 is integrally formed on the tableting base 100 so that twisting does not occur even when impacted by air pressure, thereby preventing tableting failure and damage to the nail guide piece 130. Not only that, the thickness of the nail guide piece 130 is also made thicker to better withstand external shocks.

After using the tableting machine as described above, if the contact pin 152 of the guide rib 150 is removed from the target position, the guide rib 150 is restored to its original state by the elasticity of the spring 156 and at the same time the locking device of the trigger Locked.

On the other hand, when a simple repair, such as removal of foreign matter of the nail guide groove 131 is required to rotate the safety guide piece 140 in the upward direction to clean the nail guide groove 131 and the holder groove 61. On the contrary, when the parts need to be replaced, the necessary parts may be replaced by disassembling the tableting machine in the reverse order to the above-described combination.

As described above, in the present invention, the structure of the nail guide piece becomes simpler and is integrally formed on the tableting main body, and the safety guide piece is coupled to the lock device of the trigger through the outside of the nail guide piece, thereby providing convenience of disassembly. In addition, there is an effect that can simplify the production work and reduce the production cost.

In addition, since the nail guide piece is integrally formed on the tableting main body, the torsion of the nail guide piece is prevented even by the impact caused by the tableting operation, thereby preventing tableting failure and failure.

In addition, the thickness of the nail guide piece is formed to be somewhat thick, there is another effect that the damage of the tableting machine is less due to the impact of the tableting operation is longer.
