In construction projects, a large number of steel cages are often required. The steel cages are mostly formed by combining circular steel bars and multiple strip steel bars. Subsequently, the stability of the building is improved by pouring concrete. In the preparation of steel cages, a bending device is often required to bend the steel bars to facilitate the preparation of steel cages and improve the efficiency of construction.

[0003] A palm-closing directional straightening, cutting and bending multi-functional machine for steel bar processing disclosed in a patent application with the reference publication number CN104259341A has the functions of straightening, cutting and bending, and can complete the processing steps of steel bars at one time.

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0023] Embodiment 1: The present invention provides a technical solution: As Figures 1 to 13As shown, a fully automatic cold-rolled ribbed steel bar cutting and bending processing equipment includes a processing table 1. The side walls of the processing table 1 are all open, and cabinet doors are added at the open places around the processing table 1. The cabinet doors are movably connected to the processing table 1 for easy subsequent opening. Rollers are provided at the four corners of the bottom of the processing table 1, and the movement of the processing table 1 is completed by the rollers. Lifting rings are added at the four corners of the upper surface of the processing table 1 for easy subsequent lifting and use. A circular open area 2 is opened through the middle position of the processing table 1. The circular open area 2 is interconnected with the processing table 1. A forming mechanism is added in the circular open area 2. The forming mechanism extends into the processing table 1 and is set during the addition.

A cutting mechanism is installed on one side of the upper surface of the processing table 1, and a steel bar body 3 is installed on the cutting mechanism. A limiting mechanism is combined and installed on the forming mechanism. The limiting mechanism is used to complete the clamping and guiding of the steel bar body 3. At the same time, a plurality of limiting members are arranged in a circular array around the forming mechanism. The specific number of the limiting members can be freely increased according to the construction environment, so as to ensure the accuracy of the construction of the steel bar body 3. The bending and forming processing of the steel bar body 3 is completed by the limiting mechanism, the forming mechanism and the plurality of limiting members.

[0024] Among them, electrical components such as the switching motor 9, No. 1 hydraulic cylinder 12, No. 2 hydraulic cylinder 17, No. 3 hydraulic cylinder 277, electric cylinder 28 and hydraulic press 21 are all connected to switches through wires, and the switches are electrically connected to the controller, and the specific structure of the controller is not limited.

[0025] Embodiment 2: Based on the molding mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the molding mechanism.

[0026] like Figures 5 to 7 As shown, the forming mechanism includes a disc 4 concentrically arranged in a circular open area 2, a circular ring member 5 is slidably sleeved on the outside of the disc 4, the disc 4 and the circular ring member 5 have the same thickness, the circular ring member 5 can move up and down in the circular open area 2, the disc 4 and the circular ring member 5 together form a circular structure, and an avoidance area 6 is concavely arranged inwardly at the edges of the disc 4 and the circular ring member 5, and the avoidance area 6 on the disc 4 and the circular ring member 5 is arranged in parallel, and the avoidance area 6 can complete the active avoidance operation of the restriction mechanism; It should be noted that during the bending process: by providing a forming mechanism, the steel bar body 3 is introduced through the cutting mechanism, and the front end of the steel bar body 3 is driven to contact the clamping member 27 of the limiting mechanism to complete fixation. Then, the switching motor 9 is started, and the disc 4 and the ring member 5 are controlled to rotate through the switching shaft 8. At the same time, the limiting mechanism drives the steel bar body 3 to move along with the side wall of the ring member 5, so that the steel bar body 3 is gradually bent into a circular shape. And during the bending process, the steel bar body 3 gradually contacts multiple limiting members again to complete extrusion, so that the steel bar body 3 can successfully complete the bending process, making the overall bending process time-saving and labor-saving and easy to operate; Among them, the switching mechanism includes a concave frame 7 installed in the processing table 1. A switching shaft 8 is rotatably installed at the middle position of the concave frame 7. The top of the switching shaft 8 is detachably and fixedly connected to the lower surface of the disc 4. A switching motor 9 is installed on the lower surface of the concave frame 7. The output end of the switching motor 9 is drivingly connected to the switching shaft 8. An annular track 10 is concentrically installed on the lower surface of the ring member 5. An annular member 11 is rotatably installed in the annular track 10. Two first hydraulic cylinders 12 are symmetrically installed on the concave frame 7. The output ends of the two first hydraulic cylinders 12 are detachably and fixedly connected to the lower surface of the annular member 11. A plurality of lifting tracks 13 are circularly arranged around the switching shaft 8. A lifting arm 14 is slidably engaged in each of the plurality of lifting tracks 13. The plurality of lifting arms 14 are jointly detachably and fixedly connected to the lower surface of the ring member 5. The guiding operation of the up and down movement of the ring member 5 is completed through the lifting arm 14 and the lifting track 13; It should be noted that during the switching and bending process: by providing a switching mechanism, since the ring member 5 and the disc 4 can be separated, then the first hydraulic cylinder 12 is started to pull the annular member 11, the annular track 10 and the ring member 5 to move downward synchronously and contract into the circular open area 2, so that the disc 4 is exposed. Then, the position of the cutting mechanism is finely adjusted followingly through the second hydraulic cylinder 17, so that the steel bar body 3 can be smoothly fed to the edge of the disc 4. Then, repeating the above bending work again can complete the bending work of the steel bar body 3. Since the circumferential lengths of the ring member 5 and the disc 4 are different, different-sized circular bending processes can be completed, which is convenient for the staff to freely switch and use according to requirements. After the subsequent bending is completed, the ring member 5 can be pushed back to its original position through the first hydraulic cylinder 12. And the ring member 5 is connected to the switching shaft 8 through a plurality of lifting arms 14 and lifting tracks 13, so that the ring member 5 can always receive the power output of the switching shaft 8 during the up and down movement. At the same time, the design of the annular member 11 and the annular track 10 is adopted to avoid the movement interference between the ring member 5 and the first hydraulic cylinder 12 during the rotation of the ring member 5, so that the movements of the two are separated from each other; In an embodiment of the present invention, the limiting mechanism includes a fixing frame 25 fixedly installed at the center of the disc 4. An adjusting arm 26 is slidably penetrated through the top of the fixing frame 25. A clamping member 27 is detachably and fixedly installed at the front end of the adjusting arm 26. The clamping member 27 clamps and guides the steel bar body 3. The clamping member 27 can be hidden in the avoidance area 6. An electric cylinder 28 is fixedly penetrated through the bottom of the fixing frame 25. The output end of the electric cylinder 28 is detachably and fixedly connected to the tail of the adjusting arm 26; It should be noted that when assisting in bending the steel bar body 3: by providing a limiting mechanism, during the initial docking, the electric cylinder 28 is used to push the adjusting arm 26 to move, so that the clamping member 27 extends out of the avoidance area 6 and comes into contact with the front end of the steel bar body 3. Then, the third hydraulic cylinder 277 is started to push the upper clamping block 272 downward to contact the steel bar body 3. During the downward movement of the clamping block 272, the first rack 275 is driven to move downward synchronously. Through the rotation of the driving gear 274, the second rack 276 and the lower clamping block 272 obtain an upward movement amount, so that the two clamping blocks 272 move closer to and away from each other, facilitating precise clamping of the steel bar body 3. Synchronous control of the two clamping blocks 272 can be achieved, reducing the clamping difficulty. After that, the clamping member 27 rotates synchronously with the disc 4 and the circular member to complete the guiding. After the bending is completed, the third hydraulic cylinder 277 is started again to complete the reset, and the clamping member 27 is actively moved into the avoidance area 6, enabling quick picking up of the bent steel bar body 3 and avoiding obstruction by the clamping member 27. When using the disc 4 for bending, it is only necessary to control the third hydraulic cylinder 277 to move the clamping member 27 near the disc 4, so that the clamping member 27 is hidden in the avoidance area 6 of the disc 4, and active fine-tuning can be achieved according to the bending work of the disc 4 and the circular member; The clamp 27 includes a clamp seat 271 installed at the front end of the adjustment arm 26, and two clamp blocks 272 are symmetrically slidably engaged and installed on the clamp seat 271. The two clamp blocks 272 are in close contact with the steel bar body 3. In order to improve the stability of the clamp block 272, an electromagnet is hidden inside the clamp block 272. The multiple fixation of the steel bar body 3 is completed through the cooperation of the electromagnet and the clamp block 272, ensuring the stability of the clamping of the steel bar body 3. The technicians can freely install the electromagnet according to the processing environment. A conversion area 273 is opened through the clamp seat 271, and a driving gear 27 is installed in the middle position of the conversion area 273 through the bracket. 4. A rack gear 275 is slidably engaged on one side of the inner wall of the conversion zone 273, and the tail of the rack gear 275 is fixedly connected to one of the clamping blocks 272. A rack gear 276 is slidably engaged on the other side of the inner wall of the conversion zone 273, and the tail of the rack gear 276 is fixedly connected to another clamping block 272. The rack gears 275 and 276 are both meshed and connected with the driving gear 274, and a hydraulic cylinder 277 is fixedly installed on the top of the clamping seat 271. The output end of the hydraulic cylinder 277 is detachably fixedly connected to the clamping block 272 at the top, and the synchronous driving operation of the two clamping blocks 272 is completed by the hydraulic cylinder 277.

[0028] like Figure 8 As shown, the cutting mechanism includes an adjustment track 15 provided on one side of the upper surface of the processing table 1, a slide seat 16 is slidably engaged in the adjustment track 15, and a No. 2 hydraulic cylinder 17 is installed on one side of the adjustment track 15, the output end of the No. 2 hydraulic cylinder 17 is transmission-connected with one side of the slide seat 16, a No. 1 concave seat 18 is detachably fixedly installed on the slide seat 16, a knife seat 19 is installed at the bottom of the No. 1 concave seat 18, a cutting knife 20 is slidably engaged in the top of the No. 1 concave seat 18, and a hydraulic press is fixedly installed on the top of the No. 1 concave seat 18. 21, the output end of the hydraulic press 21 is connected to the cutter 20 by transmission, and the cutting action of the steel bar body 3 is completed by the cooperation of the cutter 20 and the knife seat 19. A horizontal plate 22 is extended on both sides of the No. 1 concave seat 18, and a plurality of guide members are installed side by side on the horizontal plate 22. The steel bar body 3 is guided and transported by the plurality of guide members. Each guide member includes a fixed seat 23 installed on the horizontal plate 22, and two guide wheels 24 are symmetrically and rotatably installed on the fixed seat 23. The two guide wheels 24 are both in rotational contact with the steel bar body 3; It should be noted that when the steel bar body 3 is conveyed and cut: by providing a cutting mechanism, first, the steel bar body 3 is fed into a plurality of guiding members by an external conveying device. The guiding wheels 24 on the guiding members are used to rotate and guide the conveyance of the steel bar body 3, and the steel bar body 3 is introduced between the cutting knife 20 and the knife seat 19, so that the steel bar body 3 can move forward smoothly. And when the steel bar body 3 is conveyed to a predetermined length, the external control system starts the second hydraulic cylinder 17 to push the cutting knife 20 downward to complete the rapid cutting operation of the steel bar body 3. Subsequently, continuous bending processing can be completed by conveying again. And the cutting mechanism can move back and forth through the second hydraulic cylinder 17, and can perform fine adjustment back and forth for the bending processing of the disc 4 and the ring part 5, so that the steel bar body 3 can be accurately conveyed onto the disc 4 and the ring part 5, which is convenient for subsequent bending processing.

The pressure roller 32 contacts the steel bar body 3 to complete the guidance, and the pressure roller 32 and the clamping member 27 adopt an avoidance design and do not contact to avoid damaging the pressure roller 32. And the output end of the power member 30 is detachably and fixedly connected to the tail of the push arm 31, and the power member 30 specifically adopts one of an electric slide table, a manual slide table and a hydraulic cylinder to complete the forward and backward movement operation of the push arm 31, which can be freely selected by technicians according to needs; It is worth noting that when the steel bar body 3 is extruded: by providing a limiter, when the steel bar body 3 follows the disc 4 and the circular ring 5 to bend, the pressure roller 32 on the limiter contacts the steel bar body 3 to complete the extrusion restriction, which is beneficial to the bending and forming of the steel bar body 3, and the position of the pressure roller 32 can be adjusted by moving forward and backward through the power member 30, so that the pressure roller 32 can be adapted to the use of the disc 4 and the circular ring 5 for targeted adjustment, which can play a good limiting role, flexible operation, and convenient adjustment. At the same time, in order to improve the stability of the pressure roller 32, a plurality of wedge-shaped platforms 38 are provided on the push arm 31. Under the action of 36, the stopper 37 is pushed down to contact the wedge-shaped platform 38 to complete the blocking, which can limit and fix the push arm 31, further enhancing the stability of the pressure roller 32. At the same time, when the pressure roller 32 moves toward the disk 4, the inclined surface 39 on the stopper 37 cooperates with the wedge-shaped platform 38 to complete the guidance, so that the stopper 37 moves up to complete the avoidance, and no technical personnel need to operate and adjust. At the same time, when the pressure roller 32 needs to be reset later, it is only necessary to pull the pull rod 35 upward to drive the stopper 37 to move up, and compress the reset spring 36 to separate the stopper 37 from the wedge-shaped platform 38, and the push arm 31 is no longer restricted at this time; A lifting area 33 is provided through the L-shaped seat 29, and the lifting area 33 contacts the upper surface of the push arm 31.

Specifically, the stopper 37 contacts the right-angle side wall of the wedge-shaped platform 38 to complete the limitation, and a slope 39 is provided on one side of the bottom of the stopper 37. The slope 39 is arranged toward the inclined area of ​​the wedge-shaped platform 38. The slope 39 is arranged in coordination with the wedge-shaped platform 38.
