Description

FIELD OF THE INVENTION

This invention relates to a riveting hammer for continuous riveting, capable of sequentially installing blind rivets (hereinafter referred to as rivets) for sealing metal sheets or the like, and to a method for continuously riveting rivets.

State of the art

Applicants of this invention filed a patent application in Japan No. JP 2003-103336A for a riveting hammer continuous action, shown in Fig.12-34. This continuous riveting hammer consists of a main body D, a drive section E, a rivet feeding section F and a valve section G. FIGS. 12 and 13 show a riveting hammer with the trigger button released. On Fig-19 shows a riveting hammer with the pressed button of the starting valve.

The drive section E has a small diameter oil cylinder 1 that branches off from the main body D and extends to the side, and a large diameter oil cylinder 3 that drives the oil piston 2 of the oil cylinder 1.

The oil piston 2 serves as the piston rod 7 mounted in the air cylinder 3, and the oil piston 2 and the piston 7 are integrally formed.

The oil cylinder 1 is connected to the clamping cylinder 8 through an opening 18 leading to the oil chamber 16, which is the space formed between the piston 20 of the clamping jaw body and the nose piston 28 in the clamping cylinder 8.

Position P2 indicates the second port for supplying compressed air to the front chamber 4 of the piston of the air cylinder 3 and to the air chamber 15 (Fig.16), which is located between the nose part 28 and the shell 17 of the rod. The second port P2 is connected to port f (Fig.13), which is one of the output side ports of the operating valve 53.

Position P1 denotes the first port for supplying compressed air to the rear chamber 5 (see Fig. 14), which is located behind the piston of the air cylinder 3. The first port P1 is connected to port e, which is another output side port of the operating valve 53, the description of which will be given below.

P3 indicates the third port for supplying compressed air from the rear chamber 5 of the air cylinder 3 to the control air circuit Y of the operating valve 53 in the position in front of the piston 7 (see FIG. 14).

The hopper 47 of the feed rivet section F is mounted on the lower end of the air cylinder with a pin 27. The oil cylinder 1 and the clamping cylinder 8 of the main body D are made as a unit when located approximately at right angles to each other. A hopper 9 for receiving a shank R1, which is a segment of a blind rivet R, is installed in the upper part of the inner space of the main body D. The rivet feeding section F is attached to the lower part outside the main body D.

Vacuum ejector 12 to create a vacuum inside the shank 9 for shanks is attached to the upper end of the hopper 9.

The clamping cylinder 8 has a shell 17 of the rod attached to its lower end, and has in its inner space a piston 20 of the housing of the clamping jaws. The clamping jaw body piston 20 is a bowl-shaped piston that is open at its upper end. When installed in place, the piston 20 serves as a partition between the air chamber 14, which is located above the piston 20, and the oil chamber 16, which is located below the piston 20.

Below the housing 20 of the housing of the clamping jaws is a tubular housing 21 of the clamping jaws, which is fixedly connected to the lower end of the piston made in the form of a bowl. The inner front surface of the front end of the clamping jaw housing 21 is a conical surface 22, the diameter of which gradually decreases in the direction of the front end. A pair of clamping jaws 25 is slidably inserted into the conical front surface 22.

The clamping jaws 25 are spring-loaded downward by means of a spring 23, which is located in the housing 21 for the clamping jaws, through the pusher 24 of the clamping jaws having a sharp peak.

The tube 13 for removing the shank is inserted into the housing 21 for the clamping jaws and inserted into the hopper 9 for the shanks, while the top of the tube 13 passes through the lower plate of the hopper 9 for the shanks.

The nose piston 28 is located below the clamping jaw body piston 20 and serves as a baffle between the oil chamber 16, which is located above the nose piston 28, and the air chamber 15, which is located below the nose piston 28. The tubular body 29 formed on the lower end of the nose piston 28, is slidably inserted through the stem shell 17, which forms the lower end of the clamping cylinder 8 and extends outward from the cylinder 8. The nose piece 32 is inserted into the lower end of the tubular body 29.

In the state shown in FIGS. 12, 16, 17 and 18, the front end of the clamping jaw body 21 is in contact with the lower wall 30 (FIG. 21) of the tubular body 29, and the front ends of the clamping jaws 25 are in contact with the nose piece 32 protruding from the bottom wall 30 in the shape of the letter V.

The vacuum ejector 12 constantly works when using a riveting hammer of continuous action and picks up through the tube 13 to remove the shank of the shank R1 of the rivet R, which is cut after caulking, into the hopper 9 for the shanks. At the same time, the vacuum ejector 12 holds by means of a suction force a rivet that enters the part of the clamping jaws of the clamping jaw body 21 from the clamping part 32 of the tubular body 29 of the nose piston 28. For this, the vacuum ejector 12 is connected directly to the compressed air source 50 through the line 60.

The structure described above allows the vacuum ejector 12 to operate continuously while using a continuous riveting hammer. Thus, the suction force constantly acts on the tube 13 to remove the shank and through the tube 13 on the nose piece 32 at the front end of the tubular body 29, and on the clamping jaws 25. Due to this, not only is the collection of the shank R1 cut off from the rivet R after caulking, in the shank hopper 9 using the shank extraction tube 13, but the suction force also acts on the rivet R inserted into the nose 32 from the front end of the tubular body 29, so that the rivet R can be prevented from falling out .

As shown in FIGS. 12, 14, 16-18 and 20, the rivet feeding section F is provided with an air cylinder 37 for the tape (see FIG. 20), a guide plate 43, and a hopper 47 for holding the rivet of the tape T.

In the tape air cylinder 37 is a tape piston 39, loaded in the opposite direction by a spring 38, as shown in Fig.20. The feed grab 41 is fixedly connected to the rod 40 of the belt piston 39.

The guide plate 43 has a cross-sectional shape of the mirror image of the letter C for alignment with the rivet holding tape T and the direction of the tape holding rivet T. An elongated hole 44 is made in the vertical surface of the guide plate 43. The feed grab 41 protrudes from the elongated hole 44 with a reciprocating movement. As shown in FIG. 20, the vertical surface of the guide plate 43 also has a spring plate 46 for guiding the holding rivet of the tape T by pressing the vertical part of the holding rivet of the tape T.

The blind rivet retaining tape T (or rivet retaining tape T) is made of synthetic polymer or paper and, as shown in FIG. 26, has an elongated body that has a cross-sectional shape in the form of a mirror image of the letter C. The vertical part of the rivet retaining tape T is indicated T3 and has rectangular upper legs T1 and lower legs T2 at regular intervals at its upper and lower edges. One upper foot T1 and one lower foot T2 form one pair. One pair of the upper and lower legs is separated from the next pair by a gap T7. The vertical part of T3 has feed openings, each of which is indicated by T4 and which are made at regular intervals. A through hole T5 is formed in each upper foot T1 and in each lower foot T2. To install the rivet R in the tape, the rivet R is inserted under the lower tab T2 into the through hole T5 of the lower tab T2 and the through hole T5 of the upper tab T1, until the head part R3 of the rivet R comes in contact with the upper surface of the lower tab T2.

Such rivet-retaining tape T is stored in the hopper 47 in a coiled state and is fed through the guide plate 43 with the front end forward. The feed of the holding rivet of the tape T is provided by the reciprocating movement of the tape piston 39 of the tape air cylinder 37 using the feed grapple 41, which is meshed with the feed hole T4 of the holding rivet of the tape T.

Valve section G is shown in FIGS. 13, 15 and 19. The service valve 53 is connected to the air cylinder 3 in the position indicated by the dot-dash line. Position 2 denotes a position switching control valve. 49 denotes a start valve 49 connected at a position indicated by an internal dash-dot line where the oil cylinder 1 and the clamping cylinder 8 intersect with each other. The trigger valve 49 is designed to press the push button 51 or to release it.

In the drawings, reference numeral 50 denotes a source of compressed air, such as a compressor, and ports h and o are open to air. The output side ports e and f of the operating valve 53 are connected to the first and second ports P1 and P1, respectively. The third port P3 is connected to the control air circuit Y.

The outlet side port m of the start valve 49 is connected to the control air circuit X of the operation valve 53 and to the fourth port P4, which is located at the upper end of the clamping cylinder 8. The port n of the start valve 49 is connected to the inlet side port g of the operation valve 53.

The fifth port P5 is provided in the shell 17 of the rod. The air chamber 15 is connected to port k of the tape air cylinder 37 through the fifth port P5, so that compressed air from the air chamber 15 is supplied to the tape air cylinder 37 through the port P5 from the groove 31 in the lower part of the tubular body 29 (see Fig. 19), when the nose piece 28 rises to its top dead center (see FIG. 18).

The continuous riveting hammer described above according to the prior art works as follows.

The rivet holding tape T is stored in the hopper 47 of a continuous riveting hammer, usually in a folded state. When caulking is not performed, the riveting hammer is in the state shown in FIGS. 12 and 13, the push button 51 (release) is released and the rivet R is held in the nose part 32 by the suction force of the vacuum ejector 12, which prevents the rivet R. from falling out.

When the main body R2 of the rivet R is inserted into the hole of the metal sheet 48 and the push button 51 is pressed as shown in FIG. 14, the trigger valve 49 moves as shown in FIG. 15 and causes compressed air to pass through port s to port n , then from port g of the operating valve 53 to its port e, and then from the first port P1 to the rear chamber 5 of the air cylinder 3. The air flow moves the piston 7 forward, thereby moving the oil piston 2 forward and causing the oil to flow in the oil chamber 6 into the oil chamber 16 of the clamping cylinder 8. This is when leads to the pushing of the piston 20 of the housing of the clamping jaws at a certain distance up, and the housing 21 of the clamping jaws, respectively, rises.

In this case, a pair of clamping jaws 25, which is spring-loaded downward and in contact with the nose piece 32 by means of a spring 23 through the clamping jaw pusher 24, leaves the nose piece 32 and moves down while sliding along the conical surface 22 of the clamping jaws body 21. Due to the conical surface 22, the clamping jaws 25 are brought closer together. This allows the clamping jaws 25 to hold the shank R1 of the rivet R, while the clamping jaws 25 lift. Raising the shank R1 results in compaction using the rivet R, and then the shank R1 is cut off when the head portion R3 of the rivet R at the front end of the nose piece 32 is stopped.

In this case, the air chamber 15 and the front chamber 4 of the air cylinder 3 are opened for air through the second port P2 and the ports f and h of the working valve 53, and thereby the nose piece 28 is pushed down, and the piston 20 of the clamping jaw body alone performs a lift.

When, as mentioned above, the piston 7 moves forward, the compressed air in the rear chamber 5 is supplied to the control air circuit Y through the third port P3 to advance the operating valve 53, so that the state shown in Figs. 18 and 19 is reached. Then, the compressed air from the compressed air source 50 passes through ports s, n, g and f in this sequence and is supplied to the second port P2. The compressed air of the rear chamber 5 of the air cylinder 3 passes through ports e and h in the indicated sequence and is released into the atmosphere, while the compressed air of the control air circuit X and the compressed air of the air chamber 14 pass from the third port P3 to port m and then to port about for release into the atmosphere.

Thus, the clamping jaw body piston 20 and the nose piston 28 rise to their respective top dead center points, as shown in FIGS. 16-18.

In Fig.16, the oil piston 2 and, accordingly, the piston 7 have returned to their original position, and the nose piston 28 has risen to a position near the bowl-shaped piston for releasing compressed air into the vacuum ejector 12. Therefore, the hopper 9 for the shanks is kept under vacuum. The nose piston 28 rises relative to the piston 20 of the housing of the clamping jaws to bring into contact the lower wall 30 of the tubular body 29 with the lower end of the housing 21 of the clamping jaws. At the same time, the upper end of the nose piece 32 pushes the front ends of the clamping jaws 25 upward to open the clamping jaws 25.

In FIG. 17, the clamping jaw body piston 20 and the nose piston 28 have passed each halfway of their lifting, and the shank R1 is sucked into the shank hopper 9 through the shank removal tube 13.

In FIG. 18, the clamping jaw body piston 20 and nose piston 28 each reach their respective top dead center. When the pistons 20 and 28 are at their respective dead center, compressed air is supplied from the fifth port P5 to the port k of the tape air cylinder 37 to move the tape piston forward. This leads to the movement of the feed grab 41 from one elongated hole 44 to another. In meshing with the feeding hole T4 of the holding rivet of the tape T, the feeding grapple 41 pulls the holding rivet of the tape T from the hopper 47 and moves the holding rivet of the tape T one step along the guide plate 43. Thus, the top of the shank R1 is set along the central axis below the nose 32.

Then, the push button 51 is released to put the valve section G into the state shown in FIG. 13. The start valve 49 returns to its initial state under the action of the force of the spring 52, due to which compressed air from the compressed air source 50 is supplied through port m to the control air circuit X of the operating valve 53. At this time, the compressed air of the control air circuit Y passes through the ports P3 and P2 in this sequence and then through port f to port h for release to the atmosphere.

In the above valve position, compressed air passes through port s of the start valve 49, and then through port m for supplying to the air chamber 14 from the fourth port P4, while the compressed air in the air chamber 15 passes through the ports P2, f and h in specified sequence for release into the atmosphere. This causes the piston 20 of the clamping jaw body and the nose piston 28 to move down to their respective bottom dead center points, whereby the rivet shank R1 of the rivet R enters the open clamping jaws 25 through the nose piece 32 for holding. At the same time, the front end of the nose piece 32 moves down while bending the upper and lower tabs T1 and T2 of the holding rivet of the tape T downward. The downward movement of the nose piece 32 will be described below with reference to FIGS. 21-24.

When the nose piece 32 is lowered downward, the supply of compressed air to the tape air cylinder 37 is stopped, which ensures that the compressed air leaves the tape air cylinder 37. Therefore, the tape piston returns to its original position under the action of the spring 38. On the other hand, the rivet-holding tape T, movement which is prevented in the opposite direction by the protrusion 45 of stopping the reverse movement, remains stationary, while the feed grab disengages from the feed hole T4 and moves one step forward to engage with the next feed opening T4.

At this time, the rivet-holding tape T is elastically pressed against the guide plate 43 with the guide (preventing improper alignment) of the spring plate 46 and therefore is securely engaged with the feed grapple 41 without disturbing alignment.

Thus, the preparation for caulking the next rivet R is completed.

Subsequent operations are identical to the above operations. By repeating the above operations, it is possible to sequentially perform compaction using the rivet R.

On Fig-24 shows how the nose piece 32 is lowered. In Fig.21 serves one rivet R, and the head part R3 of the main body R2 of the rivet is located inside the lower tab T2.

22, a shank R1 is inserted into the nose piece 32, while the front end of the nose piece 32 is in the process of folding the upper tab T1.

In Fig.23, the nose piece 32 is lowered further to completely bend the upper tab T1. The shank R1 passes through the nose 32 for easy entry into the clamping jaws 25. The head part R3 of the rivet main body R2 is in contact with the front end of the nose 32 and slightly bends the lower tab T2. The near end of the lower tab T2 rests on the guide plate 43. Due to the support on the guide plate 43 and the resistance exerted by the head part R3 when the lower tab T2 is bent, the rivet R completely enters the nose piece 32 until it stops at the head part R3.

24, the nose piece 32 has reached its bottom dead center when the rivet R is completely inserted into the nose piece 32. The lower tab T2 is completely bent, although not shown in the drawing. FIG. 25 shows an enlarged sectional view of a bow piece 32 of a conventional tubular body 29.

As an alternative, the rivet supply section F may be made as shown in FIGS. 28-34. On Fig shows a bottom view, and on Fig - view along arrow aa in Fig. On Fig shows a side view, and Fig.31 is an isometric view of a part of the guide plate. Structural components that are identical with the above components are indicated by the same reference numbers according to the prior art.

As shown in FIGS. 28-34, the guide plate 43 extending from the rivet feed hopper 47 of the section F has a linear feed portion 43a of a predetermined length and has a curved portion 43b behind the linear feed portion 43a where the direction of the vertical rivet holding portion T3 of the tape T is bent at a given angle β. The curved portion 43b of the guide plate 43 has a pressure plate 61 that guides the rivet holding tape T by pressing down the vertical portion T3 of the holding rivet of the tape T and which extends above the guide surface from the linear feeding portion 43a to the curved portion 43b. The end 61a of the pressure plate 61, to which the rivet holding tape T moves, smoothly changes with gradual expansion to facilitate the retention of the holding rivet of the tape T. Due to the pressure plate 61, the blind rivet holding tape T, which was supplied linearly, reliably guides from the linear feed portion 43a to curved portion 43b for bending on curved portion 43b.

The guide plate 43 is designed to guide the holding rivet of the tape T and, as shown in FIGS. 29 and 31, has guide walls 62 to allow the holding of the holding rivet of the tape T without falling from the guide plate 43. An elongated hole 44 that allows the feed grab 41 to the reciprocating movement is open in the linear feed portion 43 a of the guide plate 43. The top of the feed grab 41 protrudes from the elongated hole 44. As shown in FIG. 28 (and FIG. 20), the feed grab 41 is connected to the piston em rod 39 of the air cylinder 37 and the conveyor air cylinder 37 causes the feed gripper 41 into a linear reciprocating motion. The feed grapple 41 is engaged with the feed hole T4 of the holding rivet of the tape T, as shown in FIG. 32, and the holding rivet tape T moves one rivet forward due to the linear advance of the feed grapple 41.

FIGS. 31-34 show various stages of use of the guide plate 43. First, from the state shown in FIG. 31, the feed grab 41 moves the rivet holding tape T forward one rivet, as shown in FIG. 32. Thus, the rivet-holding tape T enters the area under the pressure plate 61 and bends along the curved portion 43b of the guide plate 43. At the same time, the vertical part T3 of the rivet-holding tape T enters the area under the pressure plate 61 and is correctly guided since the front end 61 and the pressure plate 61 is gradually expanding. Immediately after bending the tape, the shank R1 of the rivet R reaches a position that coincides with the central axis of the tubular body 29 of the nose piston, as shown in FIG.

Then the continuous riveting hammer is actuated to carry out the “caulking”. Since the rivet holding tape T is bent at this point in time, a gap L is created, as shown in FIG. 28, between the pair of upper and lower tabs T1 and T2 located in the curved portion 43b in the portion immediately following the position where the rivet holding tape T extending from the linear feed portion 43a is bent, and a pair of upper and lower tabs T1 and T2 located in the linear feed portion 43a in a position immediately before the bend position. The gap L prevents the collision of a pair of upper and lower legs T1 and T2 located immediately before the bending position, with the downwardly moving tubular body 29, as shown in Fig. 33. This allows you to minimize the interval between one rivet R and another rivet R compared with the prior art, as shown in Fig.28. In addition, the upper and lower legs T1 and T2 on the bent portion 43b do not interfere with the downward movement of the tubular body 28, since the rivet R is already in use and is no longer held by the upper and lower legs (Fig. 34).

As a result, since the interval (step) between one rivet R and another rivet R in the rivet retaining tape T can be set small, the number of rivets R loaded on a given length of the rivet holding rivet T increases, and more rivets can be stored in the hopper 47, than in prior art riveting devices.

However, a conventional continuous riveting hammer has one problem. Namely, between the air chambers 4, 14 and 15 and the oil chambers 6 and 16 defined by the oil piston 2, the clamping jaw body piston 20 and the nose piston 28, the compressed air enters the oil after repeated use from the air chambers 4, 14 and 15 oil chambers 6 and 16, leading to the formation of air bubbles in the oil. As a result, residual pressure is formed in the oil, which leads to unreliable performance of specified operations.

The following is a detailed description of this problem with reference to the drawings. Fig. 35 shows, on an enlarged scale, part A in Fig. 1. The piston 7 of the air cylinder 3 and the oil piston 2 of the oil cylinder 1 are integrally formed, and the oil piston 2 separates the oil chamber 6 in the oil cylinder 1 from the air chamber 4 of the air cylinder 3. The oil cylinder 1 is sealed with a seal 72 to prevent compressed air from air chamber 4 into the oil chamber 6 and sealed with a seal 71 to prevent oil from entering the oil chamber 6 into the air chamber 4.

However, at the stage of returning the oil piston 2 (the stage where the state shown in FIG. 14 returns to the state shown in FIG. 16), compressed air supplied from port P2 to the air chamber 4 of the air cylinder 3 pushes the air piston 7 back and in accordance with this, the oil piston 2 is retracted. At this point in time, the oil side in the oil cylinder 1 (oil chamber 6) is pulled by the oil piston 2 and falls under negative pressure. Despite the sealing provided by seals 71 and 72 to prevent air from entering, repeated operations result in the gradual penetration of compressed air in small amounts into the space between seals 71 and 72. Penetrating air builds up and eventually overcomes the seal 71, which limits the oil chamber 6, enters the oil chamber 6 and leads to the formation of air bubbles in the oil.

Fig. 36 shows, on an enlarged scale, part B in Fig. 1. The upper part is the air chamber 14 formed by the piston 20 of the clamping jaw body, and the lower part is the oil chamber 16. The piston 20 of the clamping jaw body has seals 73 and 74 to prevent compressed air from entering the air chamber 14 into the oil chamber 16. However, it is repeated back - the progressive movement of the piston 20 of the housing of the clamping jaws inevitably leads to the penetration of a small amount of air into the space between the seals 73 and 74. The penetrating air gradually increases the pressure to a level compressed air and finally penetrates into the oil chamber 16 from the seal 74, when the oil side is under negative pressure at the stage of return of the piston 20 of the housing of the clamping jaws. Thus, air bubbles form in the oil.

On Fig shown in an enlarged scale part C in figure 1. The upper part is the oil chamber 16 formed by the nose piston 28, and the lower part is the air chamber 15. Seals 76 and 77 are provided in the nose piston 28 to prevent compressed air from the air chamber 15 from entering the oil chamber 16. The nose piston 28 rises when the compressed air is supplied to the air chamber 15 and lowered when the oil chamber 16 receives hydraulic pressure. Therefore, the repeated reciprocating movement of the nose piston 28 inevitably leads to the penetration of a small amount of air from the seal 77 into the space between the seals 76 and 77. The penetrating air collects in the space between the seals 76 and 77, and the accumulated air gradually penetrates into the oil chamber in small amounts. 16 from seal 76, when the oil in the oil chamber is pulled out by the oil piston 2 and is under negative pressure in the return stage of the nose piston 28. Thus, the oil in the oil second chamber 16 are formed air bubbles.

As shown in FIG. 9, the airplane rivet has a washer R4 in addition to the shank R1, the rivet main body R2, and the head portion (flange housing) R3. When using a conventional riveting hammer, the vacuum ejector 12 operates continuously to prevent the rivet R from falling out of the nose piece 32, as well as to collect in the hopper 9 used shanks R1 that were cut off (broken off) after the caulking was completed. Accordingly, the washer R4 remains pressed against the front end of the nose piece 32 due to suction, as shown in FIG. 10, and interferes with loading the next rivet R. Thus, the riveting hammer cannot be used until the washer R4 is removed, which makes impossible to perform sequential riveting.

Although in some cases the guide plate 43 of the rivet feed section F is curved, as shown in FIGS. 31 and 34, caulking cannot be accurately performed using a conventional rivet holding tape.

Therefore, the first objective of the present invention is to provide a continuous riveting hammer in which compressed air from the air is prevented from flowing between the air chambers 4, 14 and 15 and the air chambers 6 and 16 formed by the oil piston 2, the piston 20 of the clamping jaw body and the nose piston 28. chambers 4, 14 and 15 into oil chambers 6 and 16, so that no air bubbles form in the oil in order to ensure accurate operation.

The second objective of the present invention is to provide a continuous riveting hammer in which even when the vacuum ejector 12 is operating and the suction force acts on the nose part 32, or if an airplane rivet R equipped with a washer R4 is used, the washer R4 can be removed from the nose part 32 without pressing nasal part due to suction.

A third object of the present invention is to provide a method for continuously caulking rivets using a holding rivet of a tape T, with which it is possible to perform precise riveting with a continuous riveting hammer that has a curved guide plate 43 in the rivet feeding section F.

Disclosure of invention

In a continuous riveter according to the invention, in an oil cylinder, where an oil piston separates the oil chamber of the oil cylinder from the air chamber of the air cylinder,

a sealing element on the side of the oil chamber and a sealing element on the side of the air chamber, while the part of the oil cylinder that is between the sealing elements has an air ventilation duct; and

a sealing element on the side of the oil chamber and a sealing element on the side of the air chamber are provided in the piston of the housing of the clamping jaws and in the nose piston, while the sealing elements seal the area between the oil chamber and the air chamber, and each piston between the sealing elements has an air ventilation channel.

Due to this, air penetrating from the side of the air chamber through the space between the sealing element on the side of the oil chamber and the sealing element on the side of the air chamber leaves through the air ventilation duct. Therefore, air is not collected in the space between the sealing elements, and the penetration of air into the oil chamber is excluded.

In addition, the continuous riveting hammer according to this invention comprises a rivet feeding section that has a hopper and a tape air cylinder, while the tape holding the blind rivets wound into a roll is stored in the hopper, while the tape holding the blind rivets is loaded with blind rivets, the tape air cylinder directs the blind rivet holding tape over the guide plate to supply blind rivets which are loaded into the blind holding rivet tape, wherein

a guide plate extending from the hopper of the rivet feeding section has a linear feed portion of a predetermined length and a curved portion that continuously extends the linear feed portion, and the vertical portion of the blind holding rivet tape bends at a predetermined angle;

a pressure plate that extends above the guide surface from the linear feed portion to the curved portion of the guide plate to guide the blind rivet-holding tape while pressing the vertical portion of the blind rivet-holding vertical portion downward directs the blind rivet-holding tape which is linearly fed from the linear supply portion to the curved portion using the feed grab to bend the blind rivet holder, while the feed grab performs a linear reciprocating motion voltage via rod of the air cylinder; and

the tubular body of the nose piston is located on the central axis of the blind rivet shank held by the upper foot and lower foot, which are located directly behind the curved part, where the blind rivet holding tape bends after passing through the linear feed part of the guide plate, while the central axis of the shank and the central axis of the tubular body match each other.

This adds an additional action to the above action. Since the curved portion of the guide plate is provided with a pressure plate for guiding the tape holding the blind rivets by pressing the vertical part of the tape holding the blind rivets, the rivet holding tape, which is fed linearly forward, reliably bends along the curved part of the guide plate, and the gap between the previous pair of upper and lower legs and the subsequent pair of upper and lower legs reliably increases. As a result, the interval (pitch) between one rivet R and another rivet R in the rivet holding tape T can be reduced. Therefore, it is possible to increase the number of rivets R loaded on a given length of the holding rivet of the tape T, and more rivets can be stored in the hopper 47 than is known in the art.

In addition, in the continuous riveting hammer according to this invention, the inlet hole into which the blind rivet shank is inserted is drilled in the nose piece at the front end of the tubular body of the nose piece, and a plurality of suction-diffusing holes connected to the inlet hole are drilled in the nose piece with outer circumference of the bow.

Due to this, even when the vacuum ejector operates continuously to exert a suction force on a part of the nose part, the dispersion suction holes serve to disperse and reduce the suction force when removing the rivet shank, which allows the R4 washer to fall off.

In addition, according to this invention, a method for continuous caulking of blind rivets is created, in which a special tape holding blind rivets is loaded into a special riveting hammer of continuous action during riveting for sealing, while the riveting hammer of continuous action contains:

a rivet feeding section that has a hopper and a tape air cylinder, while the tape holding the blind rivets is wound on a roll in the hopper, while the tape holding the blind rivets is loaded with blind rivets, the tape air cylinder guides the blind rivet holding tape along the guide plate for feeding one blind rivet holding the blind rivet tape one at a time, while the guide plate extends from the hopper of the rivet feeding section and has a linear feed part of a given length and is curved a second part which continuously keeps the linear conveying portion, and wherein the direction of the vertical portion of the retaining ribbon is bent blind rivet at a predetermined angle;

a pressure plate that extends above the guide surface from the linear feed portion to the curved portion of the guide plate to guide the blind rivet holding tape by pressing down the vertical portion of the blind rivet holding tape; and

a feed grab that is driven in linear reciprocating motion by a belt air cylinder for linearly supplying the blind holding rivet tape, which is then guided by a pressure plate from the linear feed portion to the curved portion for bending, while the continuous riveting hammer positions the tubular body of the nasal piston along the central axis of the shank of the blind rivet held by the upper foot and lower foot, which are located directly behind the curved part, where rzhivayuschaya blind rivet holder belt is bent after passing through the linear portion of the flow guide plate, wherein the central axis of the shank and the central axis of the tubular bodies coincide with each other,

while holding the blind rivet tape contains:

an elongated body made in the form of a mirror reflection of the letter C, while the vertical part of the elongated body has upper legs and lower legs along its upper and lower edges at small uniform intervals, while one foot and its adjacent foot are separated by a narrow slot;

feed openings made in the vertical part for supplying an elongated body in a predetermined direction;

a first through hole formed in each of the upper legs to hold the blind rivet shank that is inserted through the first through hole; and

a second through hole formed in each of the lower legs to hold the main body of the blind rivet, which is inserted through the second through hole, while the head part of the main body of the rivet rests on the inner surface of the lower foot, while the upper legs and lower legs are horizontally paired in the longitudinal direction of the vertical part, the first and second through holes are beveled at an angle that is consistent with the outer circumference of the shank and the main body of the blind rivet inserted obliquely, the slots between the upper legs and the slots between the lower legs are connected by inclined lines of folds formed on the inner front surface of the vertical part.

This method ensures that the caulking is performed in an efficient, accurate manner using a holding rivet of the tape with an increased number of rivets loaded over a predetermined length of the holding rivet of the tape.

The implementation of the invention

The following is a detailed description of the present invention with reference to the accompanying drawings.

Figure 1 shows a sectional view of an embodiment of the present invention. Figure 2 shows a block diagram of an embodiment of the present invention. Figures 1 and 2 in combination represent the entire embodiment. Figure 3 shows part A in figure 1 on an enlarged scale. Figure 4 shows part B in figure 1 on an enlarged scale. Figure 5 shows part C in figure 1 on an enlarged scale. Structural components that are identical with the components in the above-described exemplary embodiments are denoted by the same reference numbers according to the prior art. While a detailed description of these components is not repeated, a detailed description is given of the characteristic components of the present invention.

The clamping cylinder 8 has a small diameter oil cylinder 1 that branches and extends to the side, and a large diameter oil cylinder 3 that drives the oil piston 3 of the oil cylinder 1. The oil piston 2 serves as the piston rod of the piston 7 mounted in the air cylinder 2, and the oil piston 2 and the piston 7 are connected together. The oil cylinder 1 is connected to the clamping cylinder 8 through an opening 18 leading to the oil chamber 16, which is the space formed between the piston 20 of the clamping jaw body and the nose piston 28 in the clamping cylinder 8. The oil piston 2 serves to form the oil chamber 6 of the oil cylinder 1 and the air chamber 4 of the air cylinder 3. As shown in FIG. 3, the oil cylinder 1 is provided with a sealing element 71 located on the side of the oil chamber 6 and a sealing element 72 located on the side of the air chamber 4. Hour s oil cylinder 1, which is located between the sealing elements 71 and 72 has an air vent 19.

In addition, a piston 20 of the clamping jaw housing is slidably mounted inside the clamping cylinder 8 to separate the air chamber 14 above the piston 20 of the clamping jaw housing from the oil chamber 16 under the piston 20 of the clamping jaw housing. Under the piston 20 of the housing of the clamping jaws, the nose piston 28 is slidably mounted to separate the oil chamber above the nose piston 28 from the air chamber 15 under the nose piston 28. The tubular body 29 extending outward from the clamping cylinder 8 is fixedly connected to the bottom of the nose piston 28. Housing 21 clamping jaws, moving up and down in the tubular body 29, is fixedly connected to the piston 20 of the clamping jaws body.

As shown in FIG. 4, a sealing element 73 is provided on the side of the air chamber 14 and a sealing element 74 located on the side of the oil chamber 16 in the piston 20 of the clamping jaw body, wherein the sealing elements 73 and 74 seal the area between the air chamber 14 and an oil chamber 16. In each of the pistons 20 between the sealing elements 73 and 74, an air ventilation channel 75 is provided.

In addition, as shown in FIG. 5, a sealing element 76 is provided on the side of the oil chamber 16 and a sealing element 77 located on the side of the air chamber 15 in the nose piston 28, while the sealing elements 76 and 77 seal the area between the oil chamber 16 and the air chamber 15. In each of the pistons 28 between the sealing elements 76 and 77, an air ventilation channel 78 is provided.

Therefore, if compressed air on the side of the air chamber 4 of the air cylinder 3 enters from the side of the sealing element 72 into the part of the oil cylinder 1, which is located between the sealing elements 71 and 72, then the compressed air leaves the air ventilation duct 19 to the outside (into the atmosphere). This prevents pressure build-up between the sealing elements 71 and 72 above atmospheric pressure, and air does not accumulate between the sealing elements 71 and 72. Since air is prevented from entering the oil chamber 6 of the oil cylinder 1 from the sealing element 71, no air bubbles are formed in the oil of the oil chamber 6 and reliable operation is ensured.

In addition, if the compressed air on the side of the air chamber 14 of the clamping cylinder 8 enters from the side of the sealing element 73 between the sealing elements 73 and 74 of the piston 20 of the clamping jaw body, the compressed air leaves the air vent channel 75. Thus, the penetration of air into the oil chamber 16 from the sealing element 74 is prevented.

In addition, if the compressed air of the air chamber 15 enters from the side of the sealing element 77 into the part of the nose piston 28, which is located between the sealing elements 76 and 77, then the compressed air leaves the air vent channel 78. This prevents the build-up of pressure in the space between the sealing elements 76 and 77 above atmospheric pressure, and air does not accumulate between the sealing elements 76 and 77. Thus, the penetration of air into the oil chamber 16 from the side of the sealing element 76 is prevented.

Thus, the mixing of air with oil in the oil chamber 16 is prevented, and air bubbles are not formed, which ensures reliable operation.

Figure 6 shows in section and on an enlarged scale part of the bow detail. 7 shows a nose detail in front view. On Fig shows a section of the bow details. As shown in Fig.6-8, the nose piece 32 according to this invention has several dissipating force of the suction holes 33 drilled from the outer circumferential surface. The suction force dispersing holes 33 are connected to the inlet 32a into which the rivet shank R1 is inserted R.

Therefore, when the rivet R shank R1 is inserted into the inlet 32a of the nose part 32, the suction force dispersing holes 33 are blocked by the shank R1 to ensure that the suction force is created by the vacuum ejector 12. When the caulking is completed and the shank R1 is cut off for collection in the shank hopper 9, the suction force diffusing openings 33 open so that the suction force of the vacuum ejector 12 is dissipated to reduce the suction force acting on the nose piece 32. Thus, even if the vacuum ejector 12 works continuously, or an airplane rivet R is used (Fig. 9) having a washer R4, then the dispersion force of the suction hole 33 serves to disperse and reduce the suction force after the completion of caulking. Accordingly, the washer R4 necessarily disappears, in contrast to the prior art shown in FIG. 10 of the device, where the washer R4 remains attached by suction to the front end of the nose piece 32. In addition, the rivet R is firmly held in the nose part 32 by the suction force, and the shank, which is cut off from the rivet R after completion of the caulking, is collected in the hopper 9 for the shanks.

Fig. 9 shows a rivet holding tape T for use in a continuous riveter according to the invention. In Fig. 11 (A), the tape is shown in front view, in Fig. 11 (B) is a section along the line BB in Fig. 11 (A), and in Fig. 11 (C) is a bottom view.

This rivet holding tape T is an elongated body in the form of a mirror image of the letter C. The elongated body has a vertical part T3, upper legs T1 along the upper edge of the vertical part T3 and lower legs T2 along the lower edge of the vertical part T3. The upper and lower legs are spaced at small even intervals. Each upper foot T1 is separated from the adjacent upper foot T1 by a narrow slot T7, and the same applies to the lower feet. The upper legs and lower legs are arranged in pairs horizontally in the longitudinal direction of the vertical part T3.

In the vertical part T3, open rectangular feed openings T4 are provided for advancing the holding rivet of the tape T in a predetermined direction. Using the feed holes T4 and the feed grapple 41 of the tape air cylinder 37 shown in FIGS. 28 and 31, the rivet-holding tape T is advanced one rivet along the linear portion 43a of the feed of the guide plate to the curved portion 43b.

On Fig shown in the bottom view of the riveting hammer continuous action, which uses holding deaf rivets tape according to this invention. On Fig shows a view along arrow aa in Fig, illustrating the use of holding rivets tape T.

As shown in FIG. 11, a first through hole T5, through which a rivet R shank R1 is inserted to hold, is formed in the upper tab T1. The lower tab T2 has a second through hole T6 through which the rivet main body R2 is introduced to hold, and the head part R3 of the rivet main body rests on the inner surface of the lower tab T2. The first through hole T5 and the second through hole T6 have each beveled surface formed in the direction of the central axis to align with the outer circumference of the rivet R.

The first through hole T5 and the second through hole T6 are each niche-shaped to allow separation of the shank R1 and the main body R2 of the rivet R.

Groove T8 in the form of a line of the inclined fold connecting the slot T7 of the upper foot T1 with the slot T7 of the lower foot T2, is formed on the inner side of the surface of the vertical part T3. The blind rivet holding tape T is bent on the groove T8, forming an angle β between the linear feed portion 43 a and the curved portion 43 b of the guide plate (see FIG. 28). 11 C shows a bent state.

11B shows a section through the groove T3.

To use the blind rivet holding tape T according to the present invention, the blind rivet holding tape T shown in FIG. 11 is wound into a roll of a predetermined length and loaded into the hopper 47 shown in FIG. 30. Then, the top of the holding rivet of the tape is pulled out until the top reaches the end of the linear feed portion 43 a of the U-shaped guide plate.

In this case, the tubular body of the continuous riveting hammer protrudes downward (not shown), passing through the area of the curved part 43b (see Fig. 31), where there is no blind rivet holding tape T. In Figs. 28 and 30, the riveting hammer is in the process of continuous caulking and therefore, the blind rivet retaining tape extends along the curved portion 43b.

Then, the working handle of the continuous riveting hammer is pulled out to lift the tubular body 29 and released to move the feed grab 41 of the tape air cylinder 37 shown in FIGS. 28 and 32 to thereby supply one rivet R. This causes the tape T to hold the blind rivets to bend at the groove T8, so that the front of the blind rivet holding tape T, which corresponds to one rivet R, is bent at an angle β. At the same time, the front part of the holding rivet of the tape T advances towards the curved part 43b, the tubular body is lowered while the upper and lower legs T1 and T2 are folded down. Thus, the rivet R is inserted through the hole in the nose piece 32 and held by the clamping jaws 25. At this time, the rivet R is removed from the first and second through holes T5 and T6.

The bent state of the upper and lower legs T1 and T2 is identical to the bent state of a conventional blind-rivet holding tape T and is shown in Fig. 34.

In this state, the main body R2 and the head part R3 of the rivet R protrude from the nose part 32. The protruding rivet R is inserted into the hole in the metal sheet N. Then the working handle is pulled, whereby the shank R held by the clamping jaws 25 is lifted and the rivet R is flattened for caulking. The shank R1 is cut and assembled. Then the nose piece 32 and the tubular body 29 are lifted. When the handle is released, the feed grab 41 sends the rivet holding tape T forward by one rivet R, and the tubular body 29 drops down while bending the upper and lower tabs T1 and T2 down. The rivet R is caught and the riveting hammer is ready for the next caulking.

On Fig and 30 shows the upper and lower legs T1 and T2 returned from a bent state after using the rivet R for caulking.

As shown in FIG. 28, the blind rivet-retaining tape T of the present invention is folded between a pair of upper and lower tabs T1 and T2 that hold the rivet R to be used for caulking and the immediately preceding pair of upper and lower tabs T1 and T2, leaving the gap L between two pairs of paws at the apex. If there is a small T7 slot between adjacent tabs, the tabs holding the rivet R to be used in the next caulking cycle do not interfere with lowering the tubular body 29, even if the step between one rivet R and the adjacent rivet R is small. In addition, due to the fold line T8, the rivet holding tape T is reliably bent and reliable riveting is ensured.

Therefore, riveting using a continuous riveting hammer according to this invention and the above-mentioned holding rivet of the tape T provides a reliable seal. Namely, the guide plate 43 has a linear feed portion 43a and a curved portion 43b, so that the rivet-holding tape T can bend along the curved portion 43b without interference. The bending of the holding rivet of the tape T extends the pitch between the rivets, as shown in FIG. 28, and therefore, there is no interference with the tubular body 29 being lowered down. Since the rivet holding tape T is accurately bent at a given angle, the shank of the rivet R is securely located on the central axis of the tubular body 29, and proper riveting is ensured.

Industrial applicability

As described above, the continuous riveting hammer according to this invention can sequentially install rivets for sealing a metal sheet or the like, and can also sequentially install airplane rivets.
