Description

Technical Field

[0001] The utility model relates to the technical field of punch feeders, in particular to a centering and clamping device for a punch feeder. Background Art

[0002] A punch feeder is a machine for transporting materials and is an indispensable device in both light and heavy industries. It adopts a structure with a feeder arranged on each side of the punch. The front feeder feeds the material, and the rear feeder receives the material. The two machines cooperate to complete the blanking and feeding operation together.

[0003] In the prior art, when a punch feeder is in use, generally a stop device is arranged on one side and a pusher device is arranged on the other side to ensure that the sheet metal can be accurately aligned with the punch die and can accurately enter the die cavity. However, in the actual application process of this positioning method, every time the die is replaced and the width of the sheet metal changes, the stop device needs to be adjusted. This adjustment takes a lot of working time of workers, is time-consuming and laborious, and it is also difficult to ensure the adjustment accuracy, and the practicability is insufficient. Therefore, it is necessary to redesign a centering and clamping device for a punch feeder for the above problems. Summary of the Utility Model

[0012] Advantages of the present utility model:

[0013] 1.

Specific embodiments

[0022] 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Referring to Figures 1-6 , a centering and clamping device for a punch feeding machine, including a base 1. Two first slide rails 3 are slidably installed on the upper end surface of the base 1 through a first sliding mechanism. The first sliding mechanism includes a first slider 2 fixedly installed on the upper end surface of the base 1, and the first slide rail 3 is slidably installed on the outer wall of the first slider 2. The upper end surfaces of the two first slide rails 3 are fixedly installed with a workbench 4 through a fixing plate. The bottom wall of the workbench 4 is rotatably installed with a rotating plate 5. The upper end surface of the workbench 4 is rotatably installed with a ball screw 6 through a rotating groove. The outer wall of the workbench 4 is fixedly installed with a servo motor 7 connected to the ball screw 6. The outer wall of the ball screw 6 is fixedly installed with a moving plate 9 through a moving mechanism. The moving mechanism includes a moving block 8 threadedly installed on the outer wall of the ball screw 6, and the end of the moving block 8 is fixedly connected to the bottom wall of the moving plate 9.

[0024] The upper end surface of the moving plate 9 is fixedly installed with a clamp 10. Two second slide rails 12 are slidably installed on the upper end surface of the base 1 through a second sliding mechanism. The second sliding mechanism includes a second slider 11 fixedly installed on the upper end surface of the base 1, and the second slide rail 12 is slidably installed on the outer wall of the second slider 11. The outer walls of the first slider 2 and the first slide rail 3 and the inner walls of the second slider 11 and the second slide rail 12 are all I-shaped, which can increase the stability during connection. The upper end surfaces of the two second slide rails 12 are fixedly installed with bottom brackets 13 of retaining wheels. The bottom walls of the two bottom brackets 13 of retaining wheels are rotatably installed with connecting rods 14. The ends of the two connecting rods 14 are rotatably connected to the bottom wall of the rotating plate 5. The outer wall of one of the bottom brackets 13 of retaining wheels is fixedly installed with a support block 15.

[0025] A cylinder 17 is rotatably installed on the upper end surface of the support block 15 through a connection mechanism. The connection mechanism includes a connection frame 16 fixedly installed on the upper end surface of the support block 15. The cylinder 17 is rotatably installed inside the connection frame 16. The telescopic end of the cylinder 17 is fixedly connected to the outer wall of the same-side wheel blocking base frame 13. Multiple support plates 18 are fixedly installed on the upper end surfaces of the two wheel blocking base frames 13. A plurality of wheel blocks 19 are rotatably installed on the bottom wall of each support plate 18 through a connecting shaft. A plurality of moving grooves cooperating with the wheel blocks 19 are formed on the upper end surface of the workbench 4. A plurality of installation grooves are formed on the upper end surface of the workbench 4. A guide wheel is rotatably installed inside each installation groove.

[0026] When the utility model is in use, the first slide rail 3 can be slidably installed on the outer wall of the first slider 2, whereby the convenient installation of the workbench 4 and the base 1 can be realized. Subsequently, the second slide rail 12 can be slidably installed on the outer wall of the second slider 11, so as to realize the connection between the two wheel blocking base frames 13 and the base 1. When feeding a sheet, the sheet can be first placed on the upper end surface of the workbench 4 and supported by a plurality of guide wheels, thereby avoiding the bending of the sheet due to its own weight during the feeding process. Subsequently, the clamp 10 can clamp the sheet. Immediately afterwards, when the cylinder 17 pushes the wheel blocking base frame 13 on one side forward, the wheel blocking base frame 13 transmits the force to the connecting rod 14, and the connecting rod 14 pushes the rotating plate 5 to rotate. The rotating plate 5 transmits the rotational force to another connecting rod 14, and the other connecting rod 14 drives the wheel blocking base frame 13 on the other side to move forward synchronously. Thus, the two wheel blocking base frames 13 on both sides can be close to each other, so as to achieve the purpose of synchronous centering and clamping through the cooperation of multiple connecting shafts and the wheel blocks 19.

[0027] And under the telescopic action of the cylinder 17, the distance between the two wheel blocking base frames 13 can be conveniently adjusted through the cooperation of the two connecting rods 14 and the rotating plate 5. Thus, multiple groups of connecting shafts and the wheel blocks 19 on both sides can perform synchronous centering and clamping on sheets of different widths. During this process, multiple connecting shafts can drive a plurality of wheel blocks 19 to move in the moving openings. When feeding a sheet, the servo motor 7 can drive the ball screw 6 to rotate. When the ball screw 6 rotates, it can drive the moving plate 9 to move inside the rotating groove through the cooperation of the moving block 8. Thus, the moving plate 9 can drive the sheet clamped and fixed by the clamp 10 to move. Since the plurality of wheel blocks 19 are rotatably installed, they do not affect the normal feeding of the sheet when positioning the sheet.

[0028] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the utility model.
