Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, specifically relating to a sheet metal feeding fixture for a bending machine. Background Technology

[0002] A sheet metal feeding fixture for a bending machine is an auxiliary device or apparatus specifically designed for use with a bending machine. Its core function is to automate or semi-automatically transport, position, clamp, and flip sheet metal during the bending process, thereby accurately and stably transporting the sheet metal to be processed to the processing area of ​​the bending machine, such as the die compartment, and maintaining the correct posture of the sheet metal in coordination with the bending action during the bending process, ultimately improving the efficiency, accuracy, and safety of the bending operation.

[0003] However, suction cup feeding devices rely on the principle of vacuum adsorption to adsorb the board and move it to the designated position. However, this device has obvious limitations. If the surface of the board to be processed has a porous structure and the position of the suction cup cannot be adjusted as needed, the adsorption failure is very likely to occur. At this time, the sealing between the suction cup and the board is destroyed by the pores, the vacuum is difficult to maintain, and the adsorption force drops significantly. This may cause the board to fall off midway, which not only disrupts the production rhythm, but may also cause equipment collisions or personnel safety hazards, and significantly restricts the processing stability.

[0004] To address the aforementioned issues, this application proposes a sheet metal feeding fixture for a bending machine. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a sheet metal feeding fixture for a bending machine, which features improved production pace and efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plate feeding fixture for a bending machine, comprising a base plate, a controller and a first brake motor respectively disposed above the base plate, a rotating collar fixedly connected to the upper surface of the base plate, a serrated ring fixedly connected to the outer surface of the outer ring of the rotating collar, a gear fixedly connected to the power output end of the first brake motor, the gear meshing with the serrated ring, a first electric push rod disposed above the rotating collar, a second electric push rod disposed above the first electric push rod, and a slotted frame fixedly connected to the telescopic end of the second electric push rod;

[0015] Compared with existing technologies, the advantages of this invention are as follows: By setting a vacuum pump in conjunction with a telescopic hose and a suction cup frame, the vacuum adsorption function of the sheet material is realized. At the same time, the second brake motor drives the threaded rod to rotate in the slot frame. With the bidirectional thread structure of the threaded rod, each set of sliding frames can move synchronously in opposite directions or in opposite directions in the slot frame. During the movement, the adaptive extension and retraction of the telescopic hose allows the suction cup frame to automatically adjust the adsorption position according to the size and surface condition of the sheet material, which significantly improves the production rhythm and efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please see Figure 1-5 The present invention provides the following technical solution: a plate feeding fixture for a bending machine, including a base plate 1, a controller 2 and a first brake motor 20 respectively arranged on the top of the base plate 1, a rotating collar 4 fixedly connected to the upper surface of the base plate 1, a serrated ring 3 fixedly connected to the outer surface of the outer ring of the rotating collar 4, a gear 21 fixedly connected to the power output end of the first brake motor 20, the gear 21 meshing with the serrated ring 3, a first electric push rod 8 arranged above the rotating collar 4, a second electric push rod 11 arranged above the first electric push rod 8, and a slot frame 12 fixedly connected to the telescopic end of the second electric push rod 11;

[0026] The inner wall of the slot frame 12 is rotatably connected to two threaded rods 18. The inside of the slot frame 12 is slidably connected to two sets of sliding frames 22. The inner walls of the two sets of sliding frames 22 are threadedly connected to the outer surfaces of the threaded rods 18 respectively. The inner wall of each sliding frame 22 is fixedly connected to a suction cup frame 19. Two second brake motors 15 are arranged on the left side of the slot frame 12. The power output end of each second brake motor 15 is fixedly connected to the left end of the threaded rod 18. A vacuum pump 17 is arranged above the slot frame 12. The input end of the vacuum pump 17 is fixedly connected to a telescopic hose 14. The bottom end of the telescopic hose 14 is fixedly connected to the top end of the suction cup frame 19.

[0027] In this embodiment, the threaded rod 18 adopts a left- or right-hand thread design, with the threads on both sides rotating in opposite directions. By rotating in a single direction, the two sliding frames 22 can be driven to move towards each other or away from each other synchronously. The structure is simple and the adjustment is efficient. At the same time, the rotating collar 4 adopts an inner and outer ring nested structure. The outer ring can rotate freely relative to the inner ring, while the inner ring is fixedly connected to the base plate 1. This design not only ensures the flexibility of the rotation movement, but also ensures the stability of the overall structure through the fixed installation of the inner ring, providing a reliable foundation for the rotation and positioning of subsequent components. The first brake motor 20 and the second brake motor 15 are drive motors that integrate braking devices. Their core feature is that when the motor is powered off or stopped, it can quickly lock the motor shaft through a mechanical braking structure to prevent the load from shifting or reversing due to gravity, inertia, and other factors, thereby achieving functions such as precise positioning and safe parking.

[0028] Specifically, two sets of fixing pins 5 are provided on the top of the base plate 1. The bottom end of each fixing pin 5 passes through the base plate 1 and extends to the bottom of the base plate 1.

[0029] Specifically, a connecting plate 6 is fixedly connected to the bottom surface of the controller 2. The bottom surface of the connecting plate 6 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the controller 2 can be fixed by the connecting plate 6. At the same time, the controller 2 is a digital computing and operating electronic system designed for industrial environments. It stores instructions through a programmable memory and is used to perform logical operations, sequential control, timing, counting and arithmetic operations, etc. It controls various types of machinery or production processes through digital or analog input and output to realize industrial automation control.

[0030] Specifically, a connecting ring 9 is fixedly connected to the upper surface of the outer ring of the rotating collar 4. The upper surface of the connecting ring 9 is fixedly connected to the bottom end of the first electric push rod 8. In this embodiment, the first electric push rod 8 can be fixed to the rotating collar 4 through the connecting ring 9, so that the first electric push rod 8 can be used stably.

[0031] Specifically, a fixing seat 7 is fixedly connected to the bottom surface of the first brake motor 20. The bottom surface of the fixing seat 7 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the first brake motor 20 can be fixed by the fixing seat 7, and the first brake motor 20 can be made firm.

[0032] Specifically, the telescopic end of the first electric push rod 8 is fixedly connected to a fixing frame 10, and the inner wall of the fixing frame 10 is fixedly connected to the outer surface of the second electric push rod 11. In this embodiment, the first electric push rod 8 and the second electric push rod 11 can be fixed by the fixing frame 10, thereby making the devices more secure.

[0033] Specifically, a connecting frame 13 is fixedly connected to the upper surface of each second brake motor 15, and the inner top wall of each connecting frame 13 is fixedly connected to the upper surface of the slot frame 12.

[0034] Specifically, a support base 16 is fixedly connected to the bottom surface of the vacuum pump 17. The bottom surface of the support base 16 is fixedly connected to the upper surface of the slot frame 12. In this embodiment, the vacuum pump 17 can be fixed by the support base 16. At the same time, the vacuum pump 17 is a device that uses mechanical, physical, chemical or physicochemical means to pump air from a specific sealed space to reduce the gas pressure in the space and maintain it below the standard atmospheric pressure.

[0035] The working principle and usage process of this utility model are as follows: First, the fixture is fixed to the corresponding position at the feed end of the bending machine using the fixing pin 5 on the base plate 1, ensuring a stable installation and preventing shaking during feeding. Then, the operator inputs the size parameters of the sheet material to be fed through the controller 2. The controller 2 sends instructions to each execution component according to the parameters, starting the second brake motor 15 and driving the threaded rod 18 to rotate. Utilizing its left-right thread characteristics, it drives the two sets of sliding frames 22 and suction cup frames 19 to synchronously adjust the spacing until it matches the width of the sheet material. After adjustment, the second brake motor 15 is braked and locked, fixing the position of the suction cup frame 19. Next, according to the initial placement position of the sheet material, the controller 2 coordinates the actions of the first brake motor 20, the first electric push rod 8, and the second electric push rod 11. The first brake motor 20, through the meshing of the gear 21 and the sawtooth ring 3, drives the outer ring of the rotating collar 4 to rotate, adjusting the horizontal orientation of the suction cup frame 19. The first electric push rod 8 extends and retracts to adjust the height, and the second electric push rod 11 extends and retracts to adjust the depth. The suction cup frame 19 is precisely moved above the material to be fed. The vacuum pump 17 is started, and air is drawn from the suction cup frame 19 through the telescopic hose 14. The suction cup frame 19 is then adsorbed by the vacuum suction. The telescopic hose 14 extends and retracts adaptively with the suction cup frame 19 to ensure stable adsorption. After adsorption, the first electric push rod 8 retracts to lift the material, and the first brake motor 20 drives the rotating collar 4 to rotate and adjust its direction. In conjunction with the extension and retraction of the second electric push rod 11, the material is transferred to the feeding position of the bending machine. Through the fine adjustment of the first electric push rod 8 and the second electric push rod 11, the material is accurately aligned with the feeding position of the bending machine. Then, the vacuum pump 17 stops working, the suction cup frame 19 releases the material, and the feeding is completed. After the feeding is completed, all components are reset under the control of the controller 2. The first electric push rod 8 and the second electric push rod 11 return to their initial positions, the second brake motor 15 drives the threaded rod 18 to rotate in the opposite direction, the suction cup frame 19 returns to its initial spacing, and the first brake motor 20 drives the rotating collar 4 to rotate and reset, waiting for the next feeding, further improving the production rhythm and efficiency.
