[0020] The positive effects of the present invention are as follows:

[0021] A riveting device includes a nail pressing part, a nail feeding part and a nail supplying part. The nail pressing part presses the nail into the wood under the action of the first power push rod. The nail pressing part is slidably connected to the nail feeding box. The pressing force is large, the riveting strength is high, the operation difficulty of the staff is small, it does not rely on manual operation, it is labor-saving and efficient. When operating, the staff's limbs are far away from the nail pressing part, which is safer. The nail feeding part continuously supplies nails, ensuring that the nail pressing part can operate continuously, minimizing the time interval between two nail pressing operations, reducing the waste of the interval time between two nail pressing operations, and having higher operation efficiency.

[0022] The preferred embodiments of the first power push rod and the second power push rod of the riveting device of the present invention are: electric push rod, air-liquid intensifying cylinder, air cylinder or hydraulic cylinder. A specific embodiment is that the first power push rod adopts a hydraulic cylinder or an air-liquid intensifying cylinder. The hydraulic cylinder has a large force and high riveting strength. The air-liquid intensifying cylinder has a fast initial speed and a large force at the end, and can balance the fast empty stroke and the large force required at the end when driving nails. The second power push rod adopts an air cylinder, which has a fast speed and a moderate force for pressing the nail. A pressure reducing valve and a throttle valve can be arranged at the front end of the air cylinder to control the pressing force and the movement speed of the air cylinder, and the second power push rod is more controllable.

[0023] The implementation manner of the first power push rod of the riveting device of the present invention is that the motor drives the connecting rod to realize the function of driving the top iron to move up and down. This method has a simple mechanical structure and fewer components. More importantly, this method does not require additional accessories. For example, an air cylinder requires a gas source, and the gas source depends on an air compressor device, and a hydraulic cylinder requires a pump station device. It has fewer accessories and can be used by plugging in the power.

[0024] The second power push rod of the riveting device of the present invention drives the nail pressing rod to move back and forth by the second motor. Its mechanical structure is simple, without additional power accessories, and the pressing force on the nail can be adjusted at any time by controlling the rotation of the motor as needed.

[0025] The riveting device of the present invention is provided with a nail supply part, which is used to hold multiple rows of nails. When the nails in the nail supply box are exhausted, the nail supply part is driven by a vertical rod to load nails into the nail supply box, realizing automatic nail loading operation. There is no need for manual nail loading operation. When the staff operates the riveting operation, the continuity is good, the efficiency is high, and it is worry-saving and labor-saving.

[0026] In the riveting device of the present invention, when realizing the operation, multiple such devices can be arranged simultaneously to operate on the upper and lower surfaces of the keel and the wood at the same time. Therefore, there is no need to turn over the wood and the keel, the efficiency is high, and the operation is more labor-saving.

[0027] The lower surface of the nail supply box of the riveting device of the present invention is provided with indentation teeth. The nail supply box is hinged to the frame. The top iron is a T-shaped or L-shaped part. When its horizontal part moves downward, it presses the nail supply box to move downward. The indentation teeth on the lower surface of the nail supply box press out indentations on the keel, and the pits of the keel are embedded in the wood. The indentations can lock the keel and the wood, further strengthening the bonding force between the keel and the wood. For some applications with relatively small bonding force, nails can be not used, and the keel and the wood can be combined together by using the indentations of the keel. Compared with the riveting method using nails, it saves more materials and is more low-carbon and environmentally friendly. Brief Description of the Drawings

[0071] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0072] As Figures 1-5 shown, a riveting device includes: a nail pressing part, a nail feeding part and a nail supplying part; the nail feeding part includes: a nail feeding box 4, a nail pressing rod 5 and a second power push rod 7. The nail feeding box 4 is provided with a nail receiving groove 8, and the cross-sectional shape of the nail receiving groove 8 is adapted to the outer contour of the nail. The nail feeding box 4 includes a first end and a second end. A nail leakage hole 9 is provided at the first end of the nail feeding box 4, and the nail leakage hole 9 is a through hole; the nail pressing rod 5 includes: a cross rod 10 and a vertical rod 11. The vertical rod 11 is fixedly connected to one end of the cross rod 10. The body of the second power push rod 7 is fixedly connected to the second end of the nail feeding box 4, and the telescopic end of the second power push rod 7 is hinged or fixedly connected to the cross rod 10;

[0073] The nail pressing part includes: an anvil 2 and a first power push rod 3. The anvil 2 is fixedly connected to the extending end of the first power push rod 3, and the body of the first power push rod 3 is fixedly connected to the nail feeding box 4;

[0074] The nail feeding box 4 is provided with a hinge hole or shaft;

[0075] The nail supplying part includes: a nail supplying slide plate 20 and a nail pushing device. The nail pushing device is slidably or rotatably connected to the nail supplying slide plate 20, and the nail supplying slide plate 20 is fixedly connected to the nail feeding box 4.

[0076] More specifically, the keel 27 is a long groove-shaped iron sheet with a U-shaped cross-sectional shape. During construction, the wood 26 is riveted to it with nails. The anvil 2 is a device for pressing the nails into the keel 27 and the wood 26. The anvil 2 is usually in the shape of an L or a T. The anvil 2 is slidably connected to the nail feeding box 4 up and down. When it moves downward, it presses the nails into the keel 27 and the wood 26. The first power push rod 3 is the power source and guide for the up and down movement of the anvil 2. The present invention provides several preferred technical solutions, such as a cylinder, a hydraulic cylinder, an electric push rod or a gas-liquid intensifying cylinder. A specific embodiment is a hydraulic cylinder. The body of the hydraulic cylinder is fixedly connected to the nail feeding box 4. The piston rod of the hydraulic cylinder is the first power push rod 3. The first power push rod 3 drives the anvil 2 to move up and down. When the piston rod of the hydraulic cylinder extends, it drives the anvil 2 to move downward and presses the nails into the keel 27 and the wood 26. When the piston rod of the hydraulic cylinder retracts, it drives the anvil 2 to reset.

[0077] For the convenience of industrial manufacturing, the top iron 2 and the first power push rod 3 can be made into an integral body, forming a pressing unit that uses the first power push rod as the guide and the power receiver and the top iron 2 as the part that pushes the nail to move, that is, the nail pressing part. For the purpose of saving resources, the vertical plate part of the top iron 2 can be made detachably connected to the top iron body, so as to avoid wasting resources caused by replacing the whole top iron after the vertical plate is worn or damaged.

[0078] The function of the nail feeding part is to provide continuous iron nails for the top iron 2. The nail feeding box 4 is used to arrange the iron nails in an orderly manner and ensure the correct orientation of the iron nails. It includes a long strip-shaped nail receiving groove 8 inside. The cross-sectional contour shape of the nail receiving groove 8 is adapted to the shape of the nail. One implementation is a Y shape, which just fits the shape of the nail head and the nail body. Only when the posture of the nail is adapted to the shape of the nail receiving groove 8 can the nail enter the nail receiving groove 8. The nail receiving groove 8 is a groove with one end open. The nail enters from one end of the nail receiving groove 8 and advances forward under the pushing force of the nail pressing rod 5 until it encounters the front wall or the side wall of the baffle plate opposite to the nail receiving groove 8. There is a nail leakage hole 9 provided below the side wall baffle plate. The nail leakage hole 9 is a through hole. The nail receiving groove 8 is a horizontally arranged groove, while the nail leakage hole 9 is a vertically arranged groove, and the two are arranged through. When the nail receives the pushing force from above, the nail slides along the nail leakage hole 9 and is pressed into the keel 27 and the wood 26. A specific implementation is that the nail feeding box 4 is provided with two nail receiving grooves 8 arranged side by side and two nail leakage holes 9. Therefore, under the action of the top iron 2, two nails can be pressed in at one time, improving the working efficiency. Of course, three or more nail receiving grooves 8 can also be set according to needs.

[0079] The nail pressing rod 5 is a T-shaped rod. The vertical rod 11 of the T-shaped rod is used to push the nail to advance along the nail receiving groove 8. For the convenience of industrial manufacturing, the vertical rod 11 and the cross rod 10 of the T-shaped rod can be made into a rectangular square plate, a trapezoidal plate, a triangular plate or an artistic plate. The second power push rod 7 is used to provide the pushing power for the T-shaped rod. The present invention provides preferred technical solutions, such as a cylinder, a hydraulic cylinder, an electric push rod or a gas-liquid boosting cylinder. A specific implementation is that the body of the cylinder is fixedly connected to the nail feeding box 4, and the cylinder rod is hingedly connected to the cross rod 10. The cylinder rod drives the nail pressing rod 5 to advance or retreat. When the cylinder rod extends, it drives the nail pressing rod 5 to press the nail and provides the power for the nail to advance along the nail receiving groove 8. When the cylinder rod retracts, nails can be added to the nail receiving groove 8.

[0080] The nail feeding box 4 is hingedly connected to the frame. The spring 6 is used to suspend or support the nail feeding box 4. A specific implementation is that the nail feeding box 4 is provided with a hinge hole or shaft on the side away from the nail leakage hole 9. During use, the nail feeding box 4 is installed on the frame through the hinge hole or shaft. It is hingedly connected to the main body frame 1, and the spring 6 suspends the nail feeding box 4. In order to further improve the operation efficiency, in actual use, the riveting device can be symmetrically installed on the frame up and down, or multiple units can be installed side by side on the frame to work simultaneously.

[0081] When the riveting device of the present invention is used, the second power push rod 7 is controlled to retract to drive the nail pressing rod 5 to retract, and after adding nails into the nail receiving groove 8 of the nail feeding box 4, the second power push rod 7 is controlled to advance, and the nail pressing rod 5 presses the nails in the nail receiving groove 8, and the first power push rod 3 is controlled to drive the top iron 2 to move downward, and the nails located in the nail receiving groove 8 and located at the missed nail hole 9 are pressed into the keel 27 and the wood 26 under the action of the top iron 2. The first power push rod 3 is controlled to retract to drive the top iron 2 to move upward, and the nails in the nail receiving groove 8 advance one nail position under the action of the second power push rod 7 and the nail pressing rod 5, and new nails are added above the missed nail hole 9 in the nail receiving groove 8, and the next riveting cycle can be started at this moment. When the nails in the nail receiving groove 8 are used up, the vertical rod 11 approaches or touches the sensing switch 25, and the sensing switch 25 controls the second power push rod 7 to retract and drive the nail pressing rod 5 to retract. When the vertical rod 11 moves to the right side of the nail feeding box, the vertical rod 11 drives the first gear 22 to rotate an angle, and the rack 21 moves the nail feeding box 23 forward by a displacement. The nails in the nail feeding box 4 lose the support of the nail supply slide plate 20 due to the forward movement and fall into the nail receiving groove 8. With the rotation of the second motor 17, the nail pressing rod 5 moves in the opposite direction and the nails are pushed toward the nail leakage hole 9 of the nail feeding part. Because there are many rows of nails in the nail feeding box 23, it is possible to realize continuous and automatic nailing operation into the nail receiving groove 8, thereby greatly improving the riveting efficiency.

[0082] The nail supply box 23 can also be configured to clamp a plurality of nail partition plates to form a nail receiving gap relative to the baffle plates on both sides of the nail supply slide plate 20, and the nail pusher pushes the nail partition plates to move relative to the nail supply slide plate to push the nails out and drop them into the nail receiving grooves 8.

[0083] The riveting device of the present invention comprises: a nail pressing part, a nail feeding part and a nail supply part. The nail pressing part presses the nails into the keel 27 and the wood 26 under the action of the external force borne by the first power push rod 3. The nail pressing part and the nail feeding part 4 are slidably connected to the main frame 1 as a whole. The pressing force is large, the riveting strength is high, the operation difficulty of the staff is small, it does not rely on manual operation, the labor saving efficiency is high, and the staff's limbs are far away from the nail pressing part during operation, which is safer. The nail feeding part continuously supplies nails, which ensures that the nail pressing part can operate continuously, and the time interval between two nail pressing operations is minimized, which reduces the time interval between two nail pressing operations and has higher operation efficiency.

[0084] Furthermore, the nail pusher includes: a rack 21, a first gear 22 and a nail supply box 23, the nail supply box 23 is slidably connected to the nail supply slide plate 20, the rack 21 is fixedly connected to the nail supply box 23, the first gear 22 is transmission connected to the rack 21, a nail partition plate is provided inside the nail supply box 23, the first gear 22 is transmission connected to the vertical rod 11, and the first gear 22 is rotationally connected to the nail supply slide plate 20.

[0085] More specifically, a nail supply slide plate 20 and a nail pusher 23 are provided above the nail receiving groove 8. The nail supply slide plate 20 is used to hold nails, which are nails in rows bonded with glue, and the nail pusher 23 pushes out a row of nails at a time.

[0086] When the nails in the nail feeding box 4 are gradually consumed, the vertical rod 11 moves forward. When it moves to the position of the sensing switch 25, the vertical rod 11 moves backward. When the vertical rod 11 moves to the position of the first gear 22, the first gear 22 is turned to rotate an angle, and the first gear 22 drives the rack 21 to move a certain distance. The rack 21 is fixedly connected to the nail pusher 23, and the nail pusher 23 drives the nails in the nail feeding slide plate 20 to move a certain distance. The moving distance is just the distance of the nail width. An opening is provided on the nail feeding slide plate 20 close to the nail feeding box 4. The nails fall from this opening and fall into the nail receiving groove 8 of the nail feeding box 4, thereby realizing automatic stapling operation.

[0087] Further, the nail pusher includes: a second gear 28, a third gear 29, a first conveyor belt 30, a second conveyor belt 31, a first pulley 32, a second pulley 33, a third pulley 34 and a fourth pulley 35, the first pulley 32, the second pulley 33, the third pulley 34 and the fourth pulley 35 are respectively rotatably connected to the nail supply slide plate 20, the first conveyor belt 30 bypasses the first pulley 32 and the second pulley 33 in sequence, the second conveyor belt 31 bypasses the third pulley 34 and the fourth pulley 35 in sequence, the first conveyor belt 30 and the second conveyor belt 31 are provided with a nail pushing rod, the second gear 28 is transmission connected to the first pulley 32, the third gear 29 is transmission connected to the third pulley 34, the second gear 28 is transmission connected to the third gear 29, and the second gear 28 is transmission connected to the vertical rod 11.

[0088] When the nails in the nail feeding box 4 are gradually consumed, the vertical rod 11 moves forward. When it moves to the position of the sensing switch 25, the vertical rod 11 moves backward. When the vertical rod 11 moves to the position of the second gear 28, the second gear 28 is turned to rotate an angle, and the second gear 28 and the third gear 29 rotate. At this time, the first conveyor belt 30 and the second conveyor belt 31 rotate. Since the conveyor belt is provided with a nail pushing rod, the nail pushing rod drives the nails in the nail feeding slide plate 20 to move a certain distance together. The moving distance is just the distance of the nail width. The nail feeding slide plate 20 is provided with an opening on the side close to the nail feeding box 4. The nails fall from this opening and fall into the nail receiving groove 8 of the nail feeding box 4 to realize automatic stapling operation.

[0089] Furthermore, the first power push rod 3 and / or the second power push rod 7 is: an electric push rod, a gas-liquid booster cylinder, a gas cylinder or a hydraulic cylinder.

[0090] More specifically, the preferred embodiments of the first power push rod 3 and the second power push rod 7 of the present invention are: electric push rods, gas-liquid intensifying cylinders, air cylinders or hydraulic cylinders. A specific embodiment is that the first power push rod 3 uses a hydraulic cylinder or a gas-liquid intensifying cylinder. The hydraulic cylinder has a large force and high riveting strength. The gas-liquid intensifying cylinder has a fast initial speed and a large force at the end, which can balance the fast empty stroke and the large force required at the end when driving nails. The second power push rod 7 uses an air cylinder, which has a fast speed and a moderate force for pressing the nails. A pressure reducing valve and a throttle valve can be provided at the front end of the air cylinder to control the pressing force and the moving speed of the air cylinder, and the second power push rod 7 is more controllable.

[0091] Further, according to the conditions of the riveting material, the lower surface of the nail feeding box 4 is selectively provided with indentation teeth 24.

[0092] More specifically, the lower surface of the nail feeding box 4 of the keel 27 riveting machine of the present invention is provided with indentation teeth 24. The nail feeding box 4 is hinged to the main body frame. When the horizontal part of the top iron 2 moves downward, it presses the nail feeding box 4 to move downward. The indentation teeth 24 on the lower surface of the nail feeding box 4 produce indentations on the keel 27. The pits of the keel 27 are embedded in the wood 26. The indentations can lock the keel 27 and the wood 26, further strengthening the bonding force between the keel 27 and the wood 26. For some applications with relatively small bonding force, nails can be not used, and the keel 27 can be combined with the wood 26 by using the indentations of the keel 27. Compared with the riveting method using nails, it saves more materials and is more low-carbon and environmentally friendly.

[0093] If the materials to be riveted are wooden templates and wood or when the riveting part requires flatness, then there is no need to install indentation teeth or ensure the quality of the workpiece by restricting the excessive downward movement of the nail feeding box.

[0094] At the same time, for the convenience of industrial manufacturing, the indentation teeth can be made into an integral structure with the nail feeding part; in order to adapt to different use environments and materials, it can also be made into a detachable structure that is detachably connected to the nail feeding part.

[0095] For example, if it is only for riveting building wooden templates and square timbers, there is no need to set indentation teeth. If it is only for riveting light steel keels and square timbers, indentation teeth are set. If the wall thickness of the light steel keel is relatively thick or the bearing capacity of the component is not large, then there is no need to press nails, and the riveting effect can be achieved only by indentation. It can be seen from the above that when batch riveting light steel keels and square timbers or building wooden templates and square timbers, the positive effects of this device are particularly obvious.

[0096] Further, the first power push rod 3 includes: a first motor 12, a first rod 13, a second rod 14, and a slider 36. The body of the first motor 12 is fixedly connected to the nail feeding box 4. The first end of the first rod 13 is fixedly connected to the output shaft of the first motor 12. The second end of the first rod 13 is hinged to the first end of the second rod 14. The second end of the second rod 14 is hinged to the slider 36. The slider 36 is fixedly connected to the top iron and is slidably connected to the nail feeding box 4. The power push rod 3 is fixedly connected to the top iron 2 or the two are made into an integral structure.

[0097] More specifically, another preferred implementation of the first power push rod 3 includes a first motor 12, a first rod 13, a second rod 14, and a slider 36. The first motor 12 drives the first rod 13 to rotate. One end of the first rod 13 is hinged to the first end of the second rod 14, and the second end of the second rod 14 is hinged to the first power push rod 3. When the motor rotates in one direction, the first rod 13 drives the second rod 14 to move, and the second rod 14 drives the top iron 2 to move upward. When the motor moves in the other direction, the first rod 13 drives the second rod 14 to move, and the second rod 14 drives the top iron 2 to move downward. The up and down movement of the top iron 2 realizes the function of driving the nail into the wood 26.

[0098] The implementation mode of the first power push rod 3 of the riveting device of the present invention is that the motor drives the connecting rod to realize the function of driving the top iron 2 to move up and down. This method has a simple mechanical structure and fewer components. More importantly, this method does not require additional accessories. For example, an air cylinder requires a gas source, and the gas source depends on an air compressor device, and a hydraulic cylinder requires a pumping station device. With fewer accessories, it can be used by simply plugging in the power.

[0099] Further, the second power push rod 7 includes: a sliding sleeve 15, a compression spring 16, a second motor 17, a third rod 18, and a fourth rod 19;

[0100] The body of the second motor 17 is fixedly connected to the nail feeding box 4. The output shaft of the second motor 17 is fixedly connected to the first end of the third rod 18. The second end of the third rod 18 is hinged to the first end of the fourth rod 19. The second end of the fourth rod 19 is hinged to the sliding sleeve 15. The sliding sleeve 15 is slidably connected to the second end of the nail feeding box 4. The cross bar 10 is slidably connected to the sliding sleeve 15. One end of the compression spring 16 abuts against the vertical rod 11, and the other end of the compression spring 16 abuts against the sliding sleeve 15.

[0101] More specifically, the motor is a motor with a self-locking function, such as a stepper motor, a brake motor, or a motor with a worm gear reducer at the output end. The slide sleeve 15 is arranged horizontally, and a specific implementation method is that the slide sleeve 15 is provided with a through hole, the cross bar 10 is horizontally slidably connected with the through hole of the slide sleeve 15, the outer peripheral surface of the slide sleeve 15 is horizontally slidably connected with the main body frame 1 nail feeding box 4, the slide sleeve 15 can slide in the horizontal direction, the second motor 17 drives the third rod 18 to rotate, the third rod 18 is hinged with one end of the fourth rod 19, and the other end of the fourth rod 19 is hinged with the slide sleeve 15. When the second motor 17 moves in one direction, the third rod 18 drives the fourth rod 19 to move, thereby driving the slide sleeve 15 to move forward. When the second motor 17 moves in another direction, the third rod 18 drives the fourth rod 19 to move, thereby driving the slide sleeve 15 to move backward. One end of the sliding sleeve 15 abuts against one end of the compression spring 16, and the other end of the compression spring 16 abuts against the vertical rod 11. When the sliding sleeve 15 moves forward, the sliding sleeve 15 drives the compression spring 16 to press the vertical rod 11, thereby pressing the nails. When the sliding sleeve 15 moves backward, the sliding sleeve 15 drives the cross bar 10, which is provided with a cap. The sliding sleeve 15 drives the cap of the cross bar 10 and then drives the cross bar 10 and the vertical rod 11 to move backward. When the vertical rod 11 reaches the right side of the nail supply box, it turns the first gear 22 by an angle, thereby driving the nail supply box to move forward by a position. The nails in the front row of the nail supply box lose the support of the nail supply slide plate and fall into the nail supply box. At this time, the operation of automatically adding nails is realized.

[0102] The second power push rod 7 of the riveting device of the present invention is driven by the second motor 17 to drive the nail pressing rod 5 to move forward and backward. Its mechanical structure is simple and no additional power accessories are required. The pressing force on the nail can be controlled by controlling the rotation of the motor as needed and adjusted at any time.

[0103] The riveting device of the present invention is provided with a nail supply part, which is used to hold multiple rows of nails. When the nails in the nail feeding box 4 are exhausted, the nail supply part is driven by the vertical rod 11 to load nails into the nail feeding box 4, thereby realizing automatic stapling operation. Frequent manual stapling operation is not required, and the device has good continuity, high efficiency, and is worry-free and labor-saving when in use.

[0104] Furthermore, it also includes a spring 6 , one end of which is fixedly connected to the nail feeding box 4 .

[0105] When in use, the device of the present invention can be fixedly mounted on the frame to prevent the components that do not need indentation from being indented to affect the quality, and can also be hinged on the frame to improve the riveting quality of the components that need indentation reinforcement. When hingedly connected, the spring 6 abuts against or suspends the nail feeding box 4.

[0106] More specifically, in one embodiment, there are at least two sets of the nail pressing part, nail feeding part and nail supplying part of the riveting device, which are symmetrically arranged with the horizontal plane as the symmetry plane. The riveting device of the present invention is provided with a plurality of nail pressing parts, nail feeding parts and nail supplying parts. During actual operation, four sets are installed opposite to each other up, down, left and right and used together to operate on the upper and lower surfaces and the left and right sides of the keel 27 and the wood 26 at the same time. Therefore, it is not necessary to turn over the wood 26 and the keel 27, with high efficiency and labor-saving operation.

[0107] The above-described embodiments are only the preferred embodiments of the present invention, rather than an exhaustive list of all feasible embodiments of the present invention. At the same time, the orientation words in the specification, such as front, rear, left, right, up, down, etc., are for the convenience of description and are not limitations to the present invention. For those of ordinary skill in the art, any obvious changes made without departing from the principle and spirit of the present invention should be considered to be included within the protection scope of the claims of the present invention.
