[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] like Figures 1-7 As shown, this embodiment proposes...

[0050] A steel bar punching device with automatic feeding, comprising:

[0051] The frame 1 has a support platform 2 for supporting the reinforcing bars;

[0052] The feeding bin 3 is set on the frame 1. The feeding bin 3 has a feeding gap 4, which is used to convey steel bars.

[0053] Feeding component 5, which includes:

[0054] The anti-fall component 6 is slidably mounted on the frame 1 and located outside the feeding hopper 3. After sliding, the anti-fall component 6 is used to push the steel bars to the support platform 2.

[0055] The pusher assembly 8 is slidably mounted on the frame 1 and is used to push the steel bars out of the support platform 2.

[0056] In this embodiment, to address the issues of high cost, long production time, and lack of automatic feeding in the two-step stamping process of related technologies, this solution designs an automatic feeding structure for one-step stamping. Several steel bars are neatly arranged horizontally within the feeding bin 3. The outermost steel bars are engaged with the anti-drop component 6, which is located within the feeding gap 4. When feeding is needed, the drive unit drives the anti-drop component 6 to slide, causing the steel bars engaged with the anti-drop component 6 to fall onto the support platform 2. The pushing component 8 then pushes the steel bars off the support platform 2, completing the feeding process. The various feeding steps operate in a cyclical and coordinated manner, orderly stamping the steel bars arranged in the feeding bin 3. This solution is low-cost and significantly improves stamping efficiency. The support surface 15 of the feeding bin 3 is inclined, allowing subsequently arranged steel bars to slide into the feeding gap 4 under their own weight.

[0057] Furthermore, the feeding hopper 3 has several through holes 12, and also includes:

[0058] Baffle 30 is installed inside the feeding hopper 3;

[0059] The rotating shaft 13 is rotatably mounted on the frame 1 and located below the feeding hopper 3;

[0060] The pusher block 14 has several supporting surfaces 15, which cooperate with the baffle 30. After cooperation, it is used to push the steel bars into the feeding gap 4.

[0061] In this embodiment, to address the issue of reinforcing bars sliding down to the support platform 2 due to their own weight after the anti-fall component 6 slides, this solution designs a baffle 30 to block subsequent downward sliding reinforcing bars, preventing them from continuing to slide down during the upward sliding of the anti-fall component 6. The baffle 30 prevents the reinforcing bars from sliding down to the vicinity of the feeding gap 4 and continuing to slide down. When the reinforcing bars in the feeding gap 4 fall to the support platform 2, the pushing component 8 pushes them down. New reinforcing bars need to be clamped in the feeding gap 4. In this solution, the rotating shaft 13 rotates, driving the lever 14 to rotate. Since the entire feeding process is continuous, the lever 14 has several support surfaces 15 arranged along its circumference. Adjacent support surfaces 15 form the end corners for clamping the reinforcing bars. During the rotation of the rotating shaft 13, the reinforcing bars that are close to the lever 14 are pushed into the feeding gap 4.

[0062] Furthermore, the anti-fall component 6 includes:

[0063] The lifting plate 17 is slidably mounted on the frame 1;

[0064] The first clamping block 18 is rotatably mounted on the lifting plate 17. The first clamping block 18 is located within the feeding gap 4 and is used to clamp the reinforcing bars. After the lifting plate 17 rises, it is used to drive the first clamping block 18 to rise.

[0065] In this embodiment, in order to solve the problem of the steel bar being stuck in the feeding gap 4, this solution is to set a connecting shaft on the lifting plate 17, and the first clamping block 18 is rotatably set on the connecting shaft. Since the steel bar is stuck in the first clamping block 18, the weight of the steel bar drives the first clamping block 18 to rotate, and the steel bar falls to the support platform 2. After the steel bar is pushed down, the lifting plate 17 slides down.

[0066] Furthermore, the lifting plate 17 has a second locking end 19, which is used to form a limiting space 31 with the support platform 2. After the lifting plate 17 is raised or lowered, it is used to open or close the limiting space 31.

[0067] In this embodiment, to prevent the steel bars that fall onto the lifting platform from falling out of the support platform 2, a second locking end 19 is designed. When the lifting plate 17 is at its lowest point, the first locking block 18 locks a steel bar in the feeding gap 4. The weight of the steel bar causes the first locking block 18 to rotate, and the steel bar falls onto the support platform 2. The second locking end 19 prevents the steel bar that falls onto the support platform 2 from falling out of the limiting space 31 due to inertia. After the lifting plate 17 slides, it drives the connecting shaft and the second locking end 19 to slide, opening the limiting space 31. The pushing component 8 pushes the steel bar out of the limiting space 31.

[0068] Furthermore, it also includes:

[0069] A stop block 20 is set on the frame 1. The stop block 20 and the frame 1 form a feeding channel 32 and are connected to the limiting space 31.

[0070] The pusher assembly 8 includes:

[0071] The first drive unit 21 is mounted on the frame 1;

[0072] The push rod 22 has several abutment ends 33, which are slidably mounted on the frame 1 via several sliding sleeves 34. The first driving member 21 is used to drive the push rod 22 to slide along the feeding channel 32.

[0073] In this embodiment, in order to solve the problem of the steel bar not falling accurately, the solution is to slide the push rod 22 and then the abutting end 33 abuts against the steel bar located in the limiting space 31. The huge thrust causes the steel bar to slide along the feeding channel 32, thus achieving the accurate falling of the steel bar.

[0074] Furthermore, it also includes:

[0075] Conveyor 9, mounted on rack 1, includes:

[0076] Mounting bracket 10 is mounted on rack 1;

[0077] There are two snap-fit ​​pieces 11, both of which are movably mounted on the mounting frame 10. The two snap-fit ​​pieces 11 are paired and are used to snap the two ends of the reinforcing bars respectively.

[0078] In this embodiment, in order to solve the problem of conveying the reinforcing bars, the present solution uses the feeding channel 32 to accurately slide the reinforcing bars onto the snap-fit ​​pieces 11. The two ends of the reinforcing bars are snapped onto the two snap-fit ​​pieces 11 respectively, and the snapped reinforcing bars move with the snap-fit ​​pieces 11.

[0079] Furthermore, the two snap-fit ​​connectors 11 have the same structure, and each snap-fit ​​connector 11 includes:

[0080] Chain 23 is movable and mounted on mounting bracket 10;

[0081] There are several support blocks 24, which are spaced apart on the chain 23. Each support block 24 has a support groove 25, which is used to support the steel bars that fall from the support platform 2. The support groove 25 is connected to the feeding channel 32.

[0082] In this embodiment, to solve the problem of movement of the snap-fit ​​component 11, this solution involves installing several gears on the mounting frame 10. A drive unit drives the gears to rotate, and the chain 23 cooperates with the gears. After the gears rotate, they drive the chain 23 to move. The movement of the chain 23 then moves the support blocks 24 installed on the chain 23. The moving support blocks 24 support the continuously and precisely falling steel bars. By cooperating with each other in sequence, the construction period is accelerated and the labor input is reduced.

[0083] Furthermore, the connector 11 also includes:

[0084] The second locking block 26 is a plurality of them, and the plurality of second locking blocks 26 are spaced apart on the chain 23, and the second locking blocks 26 are located between two adjacent support blocks 24;

[0085] The second latching block 26 has a third latching end 27, which is used to open or close the support slot 25.

[0086] In this embodiment, to strengthen the structure, the bottom part of the second locking block 26 is installed on the chain 23, or it can be installed completely on the chain 23. Since the second locking block 26 and the support block 24 are installed on the chain 23 at intervals, the chain 23 is in a bent structure at the point where the chain 23 meshes with the gear. The bending angle of the second locking block 26 and the support block 24 have a large movement angle, which opens the support groove 25. The movement angle allows the steel bar to accurately slide into the support groove 25. When the second locking block 26 and the support block 24 are in a straight state on the chain 23, the third locking end 27 cooperates with the support block 24 to close the support groove 25.

[0087] Furthermore, it also includes:

[0088] The stamping part is slidably mounted on the frame 1. After sliding, the stamping part is used to stamp the steel bars into shape.

[0089] In this embodiment, in order to solve the problem of stamping two finished products at the same time, the two snap-fit ​​parts 11 move synchronously to move the steel bars to the stamping part station, and the stamping part presses down to stamp the steel bars snapped on the two snap-fit ​​parts 11 into two finished products.

[0090] Furthermore, the first snap-fit ​​block 18 is cylindrical and has several snap-fit ​​arcs 29 arranged along the circumference, and the reinforcing bars are used to snap into the snap-fit ​​arcs 29.

[0091] In this embodiment, in order to achieve the effect of the steel bar being snapped into the feeding gap 4, the contact area between the snapping arc 29 and the steel bar is larger, so that the steel bar is snapped into the feeding gap 4 more stably. The cylindrical first snapping block 18 is more conducive to the different snapping arcs 29 snapping into the continuously feeding steel bars after the first snapping block 18 rotates.

[0092] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
