Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a nail feeding pipe for a riveting device according to an embodiment of the present disclosure; fig. 2 is a partially enlarged schematic view of the nail supply line for the riveting apparatus of fig. 1.
As shown in fig. 1 and 2, the embodiment of the present application provides a nail feeding pipeline for a riveting device, comprising a plurality of magazine rails 1 arranged in parallel;

Meanwhile, in order to avoid the too high speed of the high pressure air flow pushing the rivet 6, the rivet 6 is caused to impact the nail feeding assembly 3 at the outlet of the magazine rail 1 violently; the buffer air circuit 4 is connected with one end of the nail feeding pipeline 2 and can split high-pressure air flow of the nail feeding system, so that after the high-pressure air flow pushes the rivet 6 to enter the magazine track 1, the pressure and the thrust are suitably reduced, and the rivet 6 is prevented from being further accelerated; on the other hand, the air flow entering the buffer air passage 4 from the nail feeding pipeline 2 is guided to the outlet of the magazine rail 1, so that an air cushion effect is formed, the rivet 6 is buffered, and the acting force of the rivet 6 impacting the nail feeding assembly 3 is reduced.
In one embodiment, the nail outlet channel 31 is arranged at intervals with the outlets of the magazine rails 1 to form a movable space 5;
the nail taking piece 33 is movably arranged in the movable space 5, and one end of the nail taking piece 33 extending out of the movable space 5 is connected with the driving piece 32. The staple taker 33 can be made free to take staples at the outlet of the different magazine rail 1 by the drive 32.
In one embodiment, the baffle 331 is provided with a guide surface a towards the outlets of the plurality of magazine rails 1; the guide surface a is arranged at intervals with the outlets of the magazine rails 1 and is communicated with the nail taking opening 332.
On the one hand, the diversion surface a can lead the outlets of the magazine rails 1 to the nail taking opening 332, so that the air pressure in the magazine rails 1 is further reduced, and the high-pressure air flow is ensured to stably and efficiently feed the rivets 6 into the magazine rails 1; on the other hand, when the rivet member 33 is used for taking out a rivet, the rivet 6 can stably and smoothly enter the rivet taking opening 332 through the guide surface a, and the rivet 6 is taken out.
In one embodiment, at least one vent hole 34 is provided in two, and arranged on both sides of the staple discharging channel 31 in an eight shape, wherein one end of the vent hole 34 is simultaneously communicated with the movable space 5 and the inlet of the staple discharging channel 31. The air ports of the two air vents 34 can flow out towards the direction away from the nail outlet channel 31, so that the influence of the discharged air flow on the nail outlet process of the nail outlet channel 31 is avoided.
In other alternative embodiments, at least one vent 34 may be provided with only one or more than 3 vents.
In one embodiment, the side wall of the tail end of one magazine rail 1 of the plurality of magazine rails 1 is provided with a vent 41, and the tail ends of the plurality of magazine rails 1 are communicated through an air passage 42;
one end of the buffer air path 4 is simultaneously communicated with the plurality of nail feeding pipelines 2, and the other end is connected to the vent hole 41.
In one use scenario, the buffer gas circuit 4 supplies gas to the outlets of the plurality of magazine rails 1 through the vent holes 41; the air flow discharged from the vent holes 41 can form an air cushion at the outlets of the plurality of magazine rails 1 through the air passages 42 at the same time.
In one embodiment, the air passage 42 may be provided with an on-off valve; after a certain rivet feeding pipeline 2 stores rivets 6; the air passage 42 communicated with the nail feeding pipeline 2 can be closed, so that the waste of air flow is avoided, and the buffering effect of the air cushion is affected.
In one embodiment, the plurality of magazine rails 1 is provided in two; the air passage 42 between the two magazine rails 1 is disposed opposite to the air vent 41 and communicates in the same straight line direction, and the straight line direction is perpendicular to the extending direction of the magazine rails 1.
In a use scene, the rivet 6 can be supplemented to the magazine rail 1 far away from the vent hole 41, and when the rivet 6 of the magazine rail 1 is supplemented, the air passage 42 is closed through the switch valve; the magazine rail 1 adjacent to the vent hole 41 is again continuously replenished with rivets 6.
In one embodiment, the buffer gas circuit 4 is provided with a regulating valve 43, the regulating valve 43 being used to vary the throughput of the buffer gas circuit 4.
In one embodiment, the regulating valve 43 changes the throughput of the buffer gas circuit 4 by regulating the path inside the buffer gas circuit 4; when the regulating valve 43 reduces the drift diameter of the buffer air passage 4, the air flow which is branched from the nail feeding pipe 2 into the buffer air passage 4 can be reduced, and the air flow which is outputted from the other end of the buffer air passage 4 to the vent hole 41 can be reduced; so that the high-pressure air flow still has higher pushing force after passing through the buffer air circuit 4, and the rivet 6 is conveyed at high speed.
In other alternative embodiments, the buffer gas path 4 is provided with an air pump (not shown in the drawings) which can supply air to the vent hole 41 to which the buffer gas path 4 is connected. The air pump can actively suck air flow from the nail feeding pipeline 2, so that the air flow of the high-pressure air flow which is split to the buffer air circuit 4 is greatly increased, the thrust of the high-pressure air flow to the rivet 6 is greatly reduced, meanwhile, the buffer effect of the buffer air circuit 4 at the vent hole 41 is increased, and the rivet 6 is prevented from being deformed or damaged due to collision to the greatest extent.
It will be appreciated by those skilled in the art that the air pump may also be operated in reverse, sucking air from the vent 41 and inputting it into the feeding duct 2, the amount of air flow of the high pressure air through the feeding duct 2 may be further increased; thereby enabling the rivets 6 to enter the magazine rail 1 at a high speed, and greatly improving the repairing efficiency of the magazine rail 1.
The embodiment of the application also provides a nail feeding method of the nail feeding pipeline, which comprises any one of the nail feeding pipelines and a nail feeding system matched with the nail feeding pipeline, wherein the nail feeding method comprises the following steps:
determining the specification and the number of rivets 6 to be supplemented;
the rivet supply system sequentially arranges the rivets 6 with the number and the specification into the rivet discharging track;
abutting the nail outlet rail of the nail supply system with a nail inlet pipeline 2 of a nail supply pipeline;
the nail supply system provides continuous high-pressure air flow to convey the rivets 6 in the nail discharge track into the nail feeding pipeline 2;
when the rivet 6 enters the rivet feeding pipeline 2, high-pressure air flow is split through a buffer air passage 4 in the rivet feeding pipeline 2;
when the rivet 6 enters the magazine rail 1, the inside of the magazine rail 1 is depressurized through at least one vent hole 34;
when the rivet 6 touches the outlet of the magazine rail 1, an air cushion is formed at the outlet of the magazine rail 1 through the buffer air circuit 4 to buffer the rivet 6.
It will be appreciated by those skilled in the art that the gauge and number of rivets 6 to be prepared by the rivet supply system will be determined by the process requirements of the riveting device. For example, the riveting device rivets a plate material having poor structural strength, and 30 rivets 6 are required for one process flow.
In a use scenario, when the rivet 6 is driven by the high-pressure air flow of the nail supply system to enter the magazine rail 1, the inside of the magazine rail 1 can be depressurized through at least one vent hole 34 at the outlet of the magazine rail 1, so that the high-pressure air flow is prevented from being blocked when entering the magazine rail 1, and the rivet 6 can be smoothly pushed by the high-pressure air flow to enter the magazine rail 1.
Meanwhile, the buffer air channel 4 is connected with one end of the nail feeding pipeline 2 to split high-pressure air flow of the nail feeding system, so that after the high-pressure air flow pushes the rivet 6 to enter the magazine track 1, the pressure and the thrust are suitably reduced, and the rivet 6 is prevented from further accelerating; on the other hand, the air flow entering the buffer air passage 4 from the nail feeding pipeline 2 is guided to the outlet of the magazine rail 1, so that an air cushion effect is formed, the rivet 6 is buffered, and the acting force of the rivet 6 impacting the nail feeding assembly 3 is reduced. It is possible to avoid that the high pressure air flow pushes the rivet 6 too fast, causing the rivet 6 to slam hard against the feed assembly 3 at the outlet of the magazine rail 1.
In one embodiment, the method of feeding nails further comprises determining the structural strength of the rivet 6 according to the rivet 6 gauge;
determining the flow speed of the air flow in the buffer air circuit 4 according to the structural strength of the rivet 6;
the greater the structural strength of the rivet 6, the lower the flow rate of the air flow in the buffer air circuit 4;
conversely, the greater the flow rate of the air flow in the buffer air path 4.
In a use scene, the reasonable velocity of flow of buffering gas circuit 4 can be set up according to the structural strength of rivet 6 for rivet 6 can reach fastest nail rate of supplying under the circumstances that its structural strength allows, thereby under the circumstances of guaranteeing rivet 6 structure and nail subassembly 3 structure reliability, the at utmost improves the nail rate of supplying of nail system.
In addition, since the rivet 6 is subjected to air resistance and friction with the rail during movement in the rail, the rivet 6 needs to be pushed by high pressure air flow to move stably during the conveying process.
However, when the rivet 6 enters the magazine rail 1, if the air tightness of the magazine rail 1 is high, the high-pressure air flow is difficult to achieve the pushing effect; the rivet 6 is subjected to smaller thrust and is easy to clamp in the middle of the magazine rail 1, and the phenomenon of clamping nails occurs; meanwhile, after the rivets 6 enter the magazine rail 1, the thrust speed of losing high-pressure air flow can be rapidly reduced, and the repairing process is completed only by means of gravity, so that the repairing time of a plurality of rivets 6 is greatly increased, and the repairing efficiency of the rivets 6 is affected.
Therefore, at least one vent hole 34 is arranged around the nail outlet channel 31 and corresponds to the outlets of the plurality of magazine rails 1; thereby reducing the air pressure in the magazine rail 1, enabling the high-pressure air to further and stably push the rivet 6 in the magazine rail 1, and efficiently completing the nailing process.
However, at this time, the rivet 6 is further accelerated to a higher speed by the high pressure air flow in the magazine rail 1, so that the rivet 6 enters the magazine rail 1 and then collides with the nail feeding assembly 3 at the outlet of the magazine rail 1, which causes a reduction in the service life of the nail feeding assembly 3 or structural damage of the rivet 6 itself.
In other alternative embodiments, the feed speed of the rivet 6 may be reduced by reducing the pressure and flow rate of the high pressure air stream. However, this approach may result in reduced speed of movement of the rivets 6 within the feed system, and in the event that the friction between the individual rivets 6 and the rail is high due to machining errors, the low pressure air flow may tend to cause jamming during the feed of the rivets 6, thereby greatly affecting the overall feed efficiency.
Therefore, the buffering air circuit 4 is arranged on the nail feeding pipeline 2 and communicated with the outlets of the plurality of magazine rails 1; on the one hand, the rivet feeding system can still use air with high air flow pressure and flow rate to efficiently and stably convey the rivet 6 when conveying the rivet 6. On the other hand, when the rivet 6 passes through the rivet feeding pipeline 2, part of air flow of high-pressure air flow is shunted into the buffer air circuit 4, so that the pressure and the thrust of the air flow received by the rivet 6 are reduced after the rivet 6 enters the rivet feeding pipeline 2, the speed of the rivet 6 is ensured not to be further enhanced, or the speed of the rivet 6 is reduced under the action of air resistance and friction force. So that the rivet 6 does not strike the feed assembly 3 at too high a speed at the outlet of the magazine rail 1. In addition, after the rivet 6 enters the rivet feeding pipeline 2, the split high-pressure air flow can still play a role in pushing the rivet 6, so that phenomena such as clamping nails and the like caused by too small pushing force of the rivet 6 can not occur.
Further, the air flow split to the buffer air path 4 is transmitted to the nail feeding pipeline 2, and the air flow of the part is output into the outlet of the magazine rail 1 through the side surface, so that an air cushion is formed by mixing the air flow and the high-pressure air flow in the magazine rail 1, and the acting force of directly striking the rivet 6 to the nail discharging assembly is further reduced. Therefore, the structure of the rivet 6 is not easy to damage under the condition of ensuring the rivet feeding efficiency, and the service life of the rivet feeding assembly 3 is greatly prolonged.
