[0002] Steel bar bending machine is one of the steel bar processing machines. The working mechanism is a horizontal working disc rotating on a vertical axis. The steel bar is placed in the dotted line position in the figure. The supporting pin is fixed on the machine bed. The center pin and the bending pin are installed on the working disc. When the disc rotates, the steel bar is bent. In order to bend steel bars of various diameters, there are several holes on the working disc to insert the bending pins, and the center pins of different diameters can also be replaced accordingly.

[0003] When using a rebar bending machine, the rebar needs to be manually fed into the processing port. Since the places where the rebar is bent have size regulations, the accuracy of manual size feeding is not high. Therefore, in view of the above problem, an automatic grabbing feeding device for a rebar bending machine is proposed. Utility Model Content

[0007] A feeding mechanism is arranged on the material trough, the feeding mechanism is connected with the vertical rod and the motor, and the feeding mechanism drives the feeding plate to move.

[0008] By means of the above structure: when it is necessary to feed the steel bar bending machine, the bracket aligns the outlet of the trough with the feeding port of the steel bar bending machine, guides the steel bars between the two feeding plates in the trough, starts the motor on the support plate, and the motor drives the feeding mechanism on the vertical rod to move, and the feeding mechanism drives the feeding plate to perform reciprocating feeding and pushing motion, the telescopic rod follows the movement of the feeding plate, and the telescopic rod drives the hollow rod to slide, and the telescopic rod and the hollow rod assist in connecting the feeding plate with the trough, and make the two feeding plates always in a parallel relationship when moving. This design drives the two feeding plates to repeatedly perform cyclical motions of clamping, feeding and separation through the assistance of the motor, and the feeding pushing distance is equal each time, which is convenient for grasping the bending position of the steel bars, eliminating the steps of manual feeding of steel bars, and improving production efficiency.

[0009] Preferably, the feeding mechanism comprises a gear, an eccentric rod, a push rod, a sleeve rod, a slide rod, a linkage plate and a slide block;

[0030] By means of the above structure: when it is necessary to feed the steel bar bending machine 1, the bracket 2 aligns the outlet of the material trough 6 with the feeding port of the steel bar bending machine 1, and guides the steel bar between the two feeding plates 10 in the material trough 6, and starts the motor 4 on the support plate 3.

The telescopic rod 8 follows the movement of the feeding plate 10, and the telescopic rod 8 drives the hollow rod 7 to slide. The telescopic rod 8 and the hollow rod 7 assist in connecting the feeding plate 10 with the material trough 6, and make the two feeding plates 10 always in a parallel relationship when moving. This design drives the two feeding plates 10 to repeatedly perform periodic movements of clamping, feeding and separation through the assistance of the motor 4, and the feeding pushing distance is equal each time, which is convenient for grasping the bending position of the steel bar, eliminating the steps of manual feeding of steel bars, and improving production efficiency.

[0031] In the utility model, the feeding mechanism includes a gear 12, an eccentric rod 13, a push rod 14, a sleeve rod 15, a slide rod 16, a linkage plate 17 and a slide block 18;

[0032] The gear 12 is fixedly connected to the vertical rod 5 and one end of the output shaft of the motor 4 respectively, the two gears 12 are meshed, the eccentric rod 13 is fixedly connected to the top of the gear 12, the push rod 14 is rotatably connected to the outer wall of the eccentric rod 13, the slider 18 is movably connected to the outer wall of the push rod 14, the push rod 14 passes through the corresponding side of the trough 6 and extends to the inside of the trough 6, the linkage plate 17 is fixedly connected to the side where the two push rods 14 are close to each other, the sleeve rod 15 is a hollow structure, the sleeve rod 15 is fixedly connected to the side where the two linkage plates 17 are close to each other, and the number of the sleeve rods 15 is two, and the slider 18 is movably connected to the outer wall of the push rod 14. The rod 16 is slidably connected to the inner wall of the sleeve rod 15, and the four slide rods 16 are fixedly connected to the corresponding feeding plates 10 respectively. The rotation of the motor 4 drives the two gears 12 and the two eccentric rods 13 to rotate synchronously. The two eccentric rods 13 drive the two push rods 14 to move relative to each other. The push rod 14 drives the slider 18, the sleeve rod 15, the slide rod 16 and the linkage plate 17 to move synchronously. The two linkage plates 17 synchronously drive the two feeding plates 10 to clamp, feed and separate the steel bars through the sleeve rod 15 and the slide rod 16. The distance of each feeding advancement is fixed, thereby realizing the control of the steel bar feeding distance.

The spring 9 is fixedly connected to the inner wall of the corresponding hollow rod 7. The spring 9 assists the telescopic rod 8 and the loading plate 10 to approach the steel bars. Since the steel bars have different sizes, when the loading plate 10 clamps the steel bars, the spring 9 will provide some buffer space to avoid the loading mechanism from getting stuck, thereby further protecting the safety of the equipment.

[0035] In the utility model, an anti-skid layer 11 is fixedly installed on the right side of the two feeding plates 10 close to each other. The anti-skid layer 11 increases the friction when in contact with the steel bars to prevent the steel bars from slipping during feeding, thereby further improving the accuracy of fixed feeding.

[0036] Embodiment 2

[0037] The difference between this embodiment and embodiment 1 is that the feeding mechanism can be replaced with two rotating columns, which are fixedly connected to the gear 12. The two rotating columns are in contact with the surface of the steel bar. The motor 4 rotates to drive the gear 12 and the two rotating columns to rotate synchronously. The rotating columns drive the steel bar forward. However, when processing steel bars of different sizes, the rotating columns cannot completely fit the surface of the steel bar. Therefore, the design of the feeding mechanism is selected.

[0038] Working principle of the utility model: when it is necessary to feed the steel bar bending machine 1, the bracket 2 aligns the outlet of the material trough 6 with the feeding port of the steel bar bending machine 1, and guides the steel bar between the two feeding plates 10 in the material trough 6, and starts the motor 4 on the support plate 3. The rotation of the motor 4 drives the two gears 12 and the two eccentric rods 13 on the motor 4 and the vertical rod 5 to rotate synchronously. The two eccentric rods 13 drive the two push rods 14 to move relative to each other, and the push rod 14 drives the slider 18, the sleeve rod 15, the slide rod 16 and the linkage plate 17 to move synchronously. The movement of the push rod 14 drives the slider 18 to slide in the slide trough. The slider 18 assists the push rod 14 in moving, always maintaining a vertical angle with the material trough 6, thereby assisting the two feeding plates 10 to always be in parallel. The relationship is that the loading plate 10 and the material trough 6 are connected by the telescopic rod 8, the hollow rod 7 and the spring 9. When the loading plate 10 moves, the spring 9 will provide some buffer space, and the two linkage plates 17 will synchronously drive the two loading plates 10 to clamp, load and separate the steel bars through the sleeve rod 15 and the slide rod 16. The anti-slip layer 11 increases the friction when contacting the steel bars to prevent the steel bars from slipping during loading, thereby further improving the accuracy of fixed loading. This design uses the motor 4 to assist in driving the two loading plates 10 to repeatedly perform periodic movements of clamping, loading and separation, and the distance of each loading advancement is equal, which makes it convenient to grasp the bending position of the steel bars, eliminates the steps of manual loading of steel bars, and improves production efficiency.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
