Description

Technical Field

[0001] The present application belongs to the field of machinery and relates to a nailing machine, and specifically to a high-speed round nailing machine. Background Art

[0002] Nail machines can be used for processing ordinary round nails, half-cap nails, large-cap nails and other nails. Existing nail machines have two structures: one is an ordinary nail machine, and the other is a conveyor-type high-speed nail machine. Among them, the punch stroke of an ordinary nail machine is very long, the speed is low, and the processing efficiency is low. The existing high-speed nail machine equipment structure is very complex, the equipment volume is large, and the biggest defect is that it cannot process short nails. The applicant has previously developed and designed a nail machine that solves the main problems of the prior art by lifting the punch. However, in further testing, it was found that since the driving structure for lifting the punch and extending the punch is realized by sliding, there are problems such as insufficient stability during operation and difficulty in ensuring processing accuracy. Utility Model Content

[0003] Based on the shortcomings of poor stability in the prior art, the present application provides a high-speed round nail driving machine.

[0004] A high-speed round nail nailing machine comprises a frame, a feeding mechanism, a clamping mechanism, a cutting mechanism, a capping mechanism, a lifting mechanism and a driving mechanism.

[0005] The main body of the frame is a rectangular cubic frame structure. A feeding mechanism, a clamping mechanism, a cutting mechanism and a punching mechanism are sequentially installed in the middle of the frame from front to back along the feeding direction. A lifting mechanism is also installed on the frame, and the lifting mechanism is connected to the punching mechanism.

[0006] The feeding mechanism, the clamping mechanism, the cutting mechanism, the punching mechanism and the lifting mechanism are all connected to the driving mechanism, wherein the punching mechanism and the lifting mechanism are both connected to the driving mechanism through a rocker structure.

[0007] By adopting the above technical scheme, the nailing machine can move the transition punch in the vertical direction when feeding and make way for the cutting mechanism processing, so that the punch stroke is shortened; the transition punch is moved away to make way, so that the cutter stroke can be greatly shortened, achieving the purpose of high-speed processing; moreover, the nailing machine is driven by a unified driving source to ensure the same action rhythm and high action coordination, wherein the punch cap mechanism and the lifting mechanism are connected to the driving mechanism through a rocker structure respectively, which has better controllability, high action stability and improved accuracy.

[0008] Furthermore, the driving mechanism includes a first driven shaft, a second driven shaft, a main shaft, a bevel gear set, a first cam, a second cam and a third cam. A main shaft is installed inside the frame, the main shaft is perpendicular to the feeding direction, and a third cam is fixed on the main shaft, and the third cam is used to drive the punching mechanism; the first driven shaft and the second driven shaft are installed in parallel and spaced apart in the frame, and the first driven shaft and the second driven shaft are both parallel to the feeding direction. Two sets of bevel gear sets are symmetrically arranged on the main shaft along the feeding direction, and the first driven shaft and the second driven shaft are driven to rotate respectively by the two sets of bevel gear sets; the first driven shaft and the second driven shaft are fixedly installed with the first cam and the second cam in sequence from front to back, the first cam is used to drive the clamping mechanism, and the second cam is used to drive the cutting mechanism and the lifting mechanism.

[0009] By adopting the above technical solution, the main shaft is connected to the driving source as the active shaft to drive other mechanisms in the equipment to operate. The third cam is installed on the main shaft to drive the punch cap mechanism to reciprocate. The main shaft drives the first driven shaft and the second driven shaft to rotate synchronously through two sets of bevel gears. The two spur bevel gears are symmetrically arranged so that the rotation directions of the first driven shaft and the second driven shaft are opposite, thereby realizing the synchronous relative or opposite operation of the components on both sides.

[0010] Furthermore, the punch cap mechanism includes a swing seat, a hinge shaft, a sleeve, a punch slide rod and a transition punch. The lower part of the swing seat is rotatably installed in the frame through the hinge shaft, the middle rear end of the swing seat abuts against the third cam fixed on the main shaft, and the swing seat swings back and forth around the hinge shaft; the upper front end of the swing seat abuts against a sleeve, and the punch slide rod is slidably installed in the sleeve. The punch slide rod is horizontally slidably arranged in the frame along the feeding direction, the front end of the punch slide rod is fixedly connected to the guide seat, the front end of the guide seat is connected to the transition punch, and the transition punch is guided and slidably arranged on the guide seat in the up and down directions; a tension spring is connected between the punch slide rod and the frame.

[0011] By adopting the above technical solution, the capping mechanism is driven by the swing seat to swing back and forth to perform reciprocating motion, and the swing seat is controlled by the third cam to realize the punching action, and control the transition punch to make the nail cap. The transition punch is floatingly installed in the vertical slide groove, and the transition punch can move up and down in the slide groove to make way for the cutting station.

[0012] Furthermore, an anti-rotation bolt is provided at the upper end of the middle portion of the sleeve, and the anti-rotation bolt passes through the sleeve and extends into a limiting bolt hole on one radial side of the punch slide rod.

[0013] By adopting the above technical solution, the sliding direction is limited by the limit bolt to prevent the deflection of the slide groove from affecting the lifting direction of the transition punch.

[0014] Furthermore, a punch cap transition wheel is installed at the position where the pendulum seat abuts the third cam, and a roller is installed at the position where the pendulum seat abuts the sleeve.

[0015] By adopting the above technical solution, the pendulum seat abuts against the third cam through the punch cap transition wheel and abuts against the sleeve through the roller, thereby reducing the sliding friction damage of the abutting surface.

[0016] Furthermore, the lifting mechanism includes a lifting seat, a top plate, a lifting return spring and a lifting plate. The top plate is fixedly mounted on a frame at a corresponding position above the lifting seat. The lifting return spring is connected to the bottom of the top plate. The lower end of the lifting return spring is connected to a lifting seat. A transition punch is slidably penetrated in the lifting seat. Lifting plates are cantilevered on both sides of the lifting seat. The cantilever ends of the lifting plates on both sides are respectively abutted against one end of a rocker rod. The rockers are all L-shaped folding rod structures. The bending position in the middle of the rocker rod is rotatably connected to the frame through a rocking shaft. The other end of the rocker rod slides and abuts against the corresponding second cam. As the second cam rotates, the rocker rod swings to drive the lifting seat to move up and down.

[0017] By adopting the above technical solution, swing rod structures are symmetrically arranged on both sides of the lifting seat, and the swing rods respectively abut against the corresponding second cams on both sides. The swing rods on both sides swing synchronously, thereby driving the lifting seat to move up and down regularly.

[0018] Furthermore, the lifting mechanism also includes a guide seat, which is fixedly mounted at the front end of the punch cap mechanism, and a vertical guide groove is provided at the front end of the guide seat; a slider is slidably connected in the guide groove, and the slider is fixedly connected to the rear end of the punch.

[0019] By adopting the above technical solution, the guide groove structure of the slide block and the guide seat effectively limits the lifting seat to only move the transition punch up and down in the vertical direction, thereby ensuring the movement accuracy.

[0020] Furthermore, the clamping mechanism includes a clamping seat, a clamping reset spring and a clamping block. Two clamping seats are symmetrically installed in the frame on both sides of the feeding direction. The two clamping seats are both connected to the frame in a limited sliding manner. The ends of the two clamping seats away from the feeding position respectively abut against the corresponding first cams; a clamping reset spring abuts between the two clamping seats; clamping blocks are fixedly installed at the ends of the two clamping seats near the wire feeding position, and the clamping blocks are prefabricated with a groove matching the outer diameter of the wire.

[0021] By adopting the above technical solution, the two clamping seats respectively abut against the first cam installed on the first driven shaft and the first cam on the second driven shaft. The first cam on the first driven shaft and the first cam on the second driven shaft are symmetrically arranged and rotate in opposite directions, so that the two clamping seats are synchronously clamped in the direction of the iron wire or loosened away from the iron wire. When the protruding end of the first cam is away from the clamping seat, the clamping seat is driven to loosen the iron wire, and the clamping block can effectively clamp the iron wire without damaging the outer surface.

[0022] Furthermore, the cutting mechanism includes a cutter and a cutter fixing block, the two cutter fixing blocks are symmetrically installed in the frame, and the sides of the two cutter fixing blocks away from each other respectively abut against the second cam of the first driven shaft and the second cam on the second driven shaft; the upper ends of the two cutter fixing blocks are respectively fixed with symmetrically arranged left and right cutters at relative positions; the second cam rotates to drive the cutters to move relative to each other; and cutting reset springs are respectively connected between the two cutter fixing blocks and the frame.

[0023] By adopting the above technical solution, the cutter fixing seats on both sides move in opposite directions and at the same speed, and the cutters perform opening and closing actions, thereby cutting the wire according to design requirements.

[0024] Furthermore, one end of the main shaft extends to the outside of the frame and is installed with a driving pulley for connecting the driving source and a synchronous pulley for driving the feeding mechanism; the feeding mechanism includes a feeding fixed frame, a feeding eccentric disk, a feeding driving wheel, a feeding driven wheel and a driving rod, the feeding fixed frame is fixedly mounted on the frame, a feeding driving shaft is installed in the feeding fixed frame, one end of the feeding driving shaft extends to the outside of the feeding fixed frame and is coaxially installed with a feeding pulley, the feeding pulley is connected to the synchronous pulley of the main shaft through a synchronous belt, the feeding driving shaft is driven by the main shaft to rotate synchronously, and the other end of the feeding driving shaft is installed with a feeding eccentric disk; a feeding driving wheel and a feeding driven wheel are correspondingly installed on the upper and lower parts of the feeding fixed frame on the radial side of the feeding driving shaft, the outer edges of the feeding driving wheel and the feeding driven wheel are connected, and one end of the driving rod is hinged on the radial side of the axial end face of the feeding driving wheel, and the other end of the driving rod is hinged on the feeding eccentric disk.

[0025] By adopting the above technical solution, the rotation of the feeding eccentric disk drives the feeding active wheel shaft to rotate at a fixed interval periodically. The feeding active wheel and the feeding driven wheel convey the iron wire through friction, thereby conveying the iron wire, punching the nail cap and shearing the nail tip.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] The transition punch of this solution can move in the vertical direction. When the cap is needed, the transition punch moves to the processing position. When shearing is needed, the transition punch moves away to make way for the cutter, thereby shortening the entire stroke of the cap. The moving strokes of the punch and the cutter are extremely short. The strokes of all moving parts are all realized by the linkage of the guide structure. The guide action is controlled by swinging, with higher precision and better stability, achieving the purpose of high-quality and high-speed processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The present application is further described in detail below in conjunction with the accompanying drawings. The accompanying drawings are only for illustrative purposes and cannot be understood as limiting the present patent; in order to better illustrate the present embodiment, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted. The positional relationships described in the accompanying drawings are only for illustrative purposes.

[0043] See attached Figure 1 , 2 As shown, a high-speed round nail nailing machine includes a frame 1, a feeding mechanism 2, a clamping mechanism 3, a cutting mechanism 6, a capping mechanism 5 and a lifting mechanism 4.

[0044] The main body of the frame 1 is a rectangular cubic frame structure, and a feeding mechanism 2, a clamping mechanism 3, a cutting mechanism 6 and a capping mechanism 5 are sequentially installed in the middle of the frame 1 from the front end to the rear end. Figure 2 The right side is the front end and the left side is the rear end.

[0045] The feeding mechanism 2 is used to feed the iron wire to be processed from front to back along the axis line direction, and the iron wire passes through the clamping mechanism 3 and the cutting mechanism 6 in sequence;

[0046] The clamping mechanism 3 is used to clamp and fix the iron wire to be processed, and cooperates with the cap punching mechanism 5 to process the nail cap;

[0047] The cutting mechanism 6 is used to cut the iron wire. When the feeding mechanism 2 conveys the iron wire that has been processed into the nail cap forward to a set length, the cutting mechanism 6 cuts the iron wire to complete the nail processing.

[0048] The cap punching mechanism 5 is used to punch the end of the iron wire to form a nail cap on the end of the iron wire.

[0049] A discharge hopper (not numbered in the figure) is installed in the frame 1 below the cutting mechanism 6 . The discharge hopper is an inclined chute structure for guiding the processed nails to be sent out of the frame 1 .

[0050] The clamping mechanism 3 and the cutting mechanism 6 are respectively connected to the driving mechanism 7 through cam matching structures, and the driving mechanism 7 drives the clamping mechanism and the cutting mechanism 6 to slide back and forth respectively.

[0051] The punching mechanism 5 is connected to the driving mechanism 7 via the swing rod 406 structure.

[0052] The punch cap mechanism 5 is also connected to a lifting mechanism 4, which can drive the transition punch 501 to rise to a processing position required for the cutting process;

[0053] The lifting mechanism 4 is connected to the driving mechanism 7 via the rocker rod 406 structure. The driving mechanism 7 drives the rocker rod 406 structure to swing according to the processing pace, thereby realizing the regular lifting and lowering of the lifting mechanism 4, and the processing action is controlled by the driving mechanism 7.

[0054] See attached Figure 2 As shown, the driving mechanism 7 specifically includes a first driven shaft 703, a second driven shaft 706, a main shaft 702, a bevel gear, a first cam 704, a second cam 705 and a third cam 707.

[0055] A first driven shaft 703 and a second driven shaft 706 are installed in parallel and at intervals in the frame 1, and the first driven shaft 703 and the second driven shaft 706 are both parallel to the feeding direction of the iron wire;

[0056] A main shaft 702 is installed at the rear of the frame 1. The main shaft 702 is perpendicular to the feeding direction of the wire. The main shaft 702 drives the first driven shaft 703 and the second driven shaft 706 to rotate through two sets of bevel gear sets 708.

[0057] The first driven shaft 703 and the second driven shaft 706 have the same structure. The first cam 704 and the second cam 705 are fixedly installed on the first driven shaft 703 and the second driven shaft 706 from front to back. The first cam 704 abuts against the clamping mechanism 3, and the second cam 705 abuts against the cutting mechanism 6 and the lifting mechanism 4. The third cam 707 is fixedly installed on the main shaft 702, and the third cam 707 abuts against the punching mechanism 5.

[0058] One end of the main shaft 702 extends to the outside of the frame 1 and is installed with a driving pulley 701 for connecting to a driving source and a synchronous belt 201 for driving the feeding mechanism 2.

[0059] See attached Figure 3 As shown, the clamping mechanism 3 includes a clamping seat 303, a clamping reset spring 301 and a clamping block 302. Two clamping seats 303 are symmetrically installed in the frame 1 on both sides of the feeding direction. The two clamping seats 303 are both limitedly slidably connected in the frame 1. The ends of the two clamping seats 303 away from the wire feeding position are respectively abutted against the corresponding first cams 704. Specifically, one of the clamping seats 303 abuts against the first cam 704 installed on the first driven shaft 703, and the other clamping seat 303 abuts against the first cam 704 installed on the second driven shaft 706, and the first cam 704 on the first driven shaft 703 is mirror-imaged with the first cam 704 on the second driven shaft 706, so that the two clamping seats 303 are clamped toward or away from the wire direction synchronously; a clamping reset spring 301 abuts between the two clamping seats 303, and the reset spring maintains pre-tension, and when the protruding end of the first cam 704 is away from the clamping seat 303, the clamping seat 303 is driven to release the wire;

[0060] A clamping block 302 is fixedly mounted at one end of the two clamping seats 303 near the wire feeding position. A groove matching the outer diameter of the wire is prefabricated on the clamping block 302. The clamping block 302 can effectively clamp the wire without damaging the outer surface.

[0061] A clamping transition wheel 304 is rotatably mounted on the clamping seat 303 at a position that can abut against the first cam 704. The clamping transition wheel 304 abuts against the first cam 704 to convert sliding friction into rotational friction, thereby avoiding friction damage to the contact surface.

[0062] See attached Figure 4 As shown, the lifting mechanism 4 includes a lifting seat 401, and the punch cap mechanism 5 includes a transition punch 501. A through hole coaxial with the feeding direction is prefabricated in the lifting seat 401, and a transition punch 501 is slidably penetrated in the through hole. The transition punch 501 is slidably connected to the lifting seat 401. In order to reduce friction, a linear bearing is installed between the through hole and the transition punch 501 to ensure that the transition punch 501 slides flexibly.

[0063] The lifting mechanism 4 also includes a guide seat 403, which is fixedly mounted at the front end of the punch cap mechanism 5. A vertical guide groove is arranged at the front end of the guide seat 403. A slider 402 is connected to the guide groove for limited sliding. The slider 402 is embedded in the guide groove of the guide seat 403 and can only slide up and down in the guide groove. The slider 402 is fixedly connected to the rear end of the punch. The structure of the slider 402 and the guide seat 403 limits the lifting seat 401 to only move the transition punch 501 up and down in the vertical direction.

[0064] See attached Figure 5 As shown, the lifting mechanism 4 also includes a top plate 408, a lifting return spring 404 and a lifting plate 405. The top plate 408 is fixed on the frame 1 at a corresponding position above the lifting seat 401, and two lifting return springs 404 are abutted between the top plate 408 and the lifting seat 401; the lifting plates 405 are cantilevered on both sides of the lifting seat 401, and the lifting plates 405 are used to abut the rocker rod 406 structure of the lifting mechanism 4, thereby driving the lifting seat 401 to move up and down.

[0065] The rocker arm 406 structure of the lifting mechanism 4 includes a rocker arm 406 and a swing shaft 407. The rocker arm 406 is an L-shaped folding rod structure. A swing shaft is installed at the bending position in the middle of the rocker arm 406. The swing shaft rotation limiter is installed on the frame 1, so that the rocker arm 406 can rotate around the swing shaft 407; one end of the rocker arm 406 slides against the lifting plate 405, and the other end of the rocker arm 406 slides against the second cam 705. As the second cam 705 rotates, the lifting seat is driven up and down by the swing rotation.

[0066] Rollers are installed at both ends of the swing rod 406 to convert sliding friction into rotational contact to reduce friction loss.

[0067] See attached Figure 5 As shown, the cutting mechanism 6 includes a cutter 601 and a cutter 601 fixing block. The two cutter 601 fixing blocks are symmetrically installed in the frame 1, and the two cutter 601 fixing blocks are symmetrically installed in the frame 1. The two sides of the two cutter 601 fixing blocks away from each other are respectively abutted against the second cam 705 of the first driven shaft 703 and the second cam 705 on the second driven shaft 706; the upper ends of the two cutter 601 fixing blocks are respectively fixed with symmetrically arranged left and right cutters 601 at relative positions; the second cam 705 rotates to drive the cutters 601 to move relative to each other, thereby cutting the iron wire.

[0068] A cut-off reset spring 604 is connected between the two cutter 601 fixing blocks and the frame 1 respectively, and the cut-off reset spring 604 maintains a pulling force to reset the cutter 601 fixing blocks.

[0069] In order to reduce friction, a cutting transition wheel 602 is installed on the fixing block of the cutter 601 at the position in contact with the second cam 705 , and the cutting transition wheel 602 abuts against the second cam 705 .

[0070] In order to adjust the cutting force of the cutter 601, a cutting wedge is provided between the fixing block of the cutter 601 and the cutter 601. The cutting force of the cutter 601 can be adjusted by manually adjusting the installation position of the cutting wedge.

[0071] See attached Figure 6 As shown, the punch cap mechanism 5 includes a swing seat 503, a hinge shaft 507, a sleeve 504, a punch slide rod 506 and a transition punch 501. A hinge shaft 507 is rotatably installed at the lower part of the swing seat 503, and the hinge shaft 507 is fixed in the frame 1. The middle rear end of the swing seat 503 abuts against the third cam 707 fixed on the main shaft 702. With the rotation of the third cam 707, the swing seat 503 swings back and forth around the hinge shaft 507; the upper front end of the swing seat 503 abuts against a sleeve 504, and the punch slide rod 506 is slidably installed in the sleeve 504. The punch slide rod 506 is horizontally slidably arranged in the frame 1 along the feeding direction, and the front end of the punch slide rod 506 is fixed to the guide seat 403, and the transition punch 501 is slidably installed in the guide seat 403.

[0072] The punch slide bar 506 is connected to the frame 1 by a tension spring, and the tension spring maintains the tension to pull the punch slide bar 506 to reset.

[0073] In order to prevent the punch slide bar 506 from deflecting, an anti-rotation bolt 505 is provided at the upper end of the middle part of the sleeve 504 . The anti-rotation bolt 505 passes through the sleeve 504 and extends into a limiting bolt hole on one radial side of the punch slide bar 506 .

[0074] In order to reduce friction damage, a punch cap transition wheel 502 is installed on the pendulum seat 503 at the abutment position with the third cam 707, and the pendulum seat 503 abuts the third cam 707 through the punch cap transition wheel 502; a roller is installed on the pendulum seat 503 at the abutment position with the sleeve 504, and abuts the sleeve 504 through the roller.

[0075] All the moving parts of the nailing machine are powered by the same driving source, which can be an external motor or a driving hand wheel, and transmitted through the driving mechanism 7 to ensure the same action rhythm and high action coordination.

[0076] See attached Figure 6As shown, the feeding mechanism 2 includes a feeding fixed frame 204, a feeding eccentric disk 202, a feeding driving wheel 205, a feeding driven wheel 206 and a driving rod 203. The feeding fixed frame 204 is fixedly mounted on the frame 1. A feeding driving shaft is installed in the feeding fixed frame 204. One end of the feeding driving shaft extends to the outside of the feeding fixed frame 204 and is coaxially installed with a feeding pulley. The feeding pulley is connected to the synchronous belt 201 wheel of the main shaft 702 through the synchronous belt 201. The feeding driving shaft is driven by the main shaft 702 to rotate synchronously. The feeding eccentric disk 202 is installed on the other end of the feeding driving shaft.

[0077] A feeding driving wheel 205 and a feeding driven wheel 206 are correspondingly installed on the upper and lower sides of the feeding fixed frame 204 on the radial side of the feeding drive shaft. The outer edges of the feeding driving wheel 205 and the feeding driven wheel 206 are connected. One end of the driving rod 203 is hinged on the radial side of the axial end face of the feeding driving wheel 205. The other end of the driving rod 203 is hinged on the feeding eccentric. The feeding eccentric disk 202 rotates to drive the feeding driving wheel 205 axis to rotate at a fixed interval period. The feeding driving wheel 205 and the feeding driven wheel 206 convey the iron wire through friction, thereby conveying the iron wire, punching the nail cap and shearing the nail tip. The required feeding length can be adjusted by adjusting the angle of the feeding driving wheel 205.

[0078] The feeding mechanism 2 can also be replaced by other existing feeding structures, as long as the feeding rhythm is consistent with the processing rhythm.

[0079] The feeding structure shown in the drawings of this embodiment is connected to the driving mechanism through a synchronous belt.
