Description

Technical Field

[0001] The invention relates to the technical field of metal processing, and in particular to a stamping auxiliary device with a positioning function. Background Art

[0002] In the field of stamping, processing metal or other material sheets into parts of specific shapes is a very common production method. However, the traditional stamping process has many significant problems, especially in the workpiece positioning link, which seriously restricts production efficiency and product quality.

[0003] In the workpiece stamping process, one is to use the stamping equipment to stamp the cut workpiece into a specific shape. During the stamping, the workpiece needs to be put in and then the stamped workpiece is taken out. The other is to use the stamping equipment to continuously stamp the sheet material and cut the sheet material into a specific shape of workpiece through stamping.

[0004] In the stamping process of continuously punching and cutting the sheet to obtain the product, the operator needs to take out the finished workpiece after each punching of the stamping equipment, and move the sheet to move the stamped part away for the next punching. In order to improve the utilization rate of the sheet, the distance between two adjacent stamping workpieces is generally made as small as possible, so as to minimize the waste of the sheet. At present, the control method of this distance currently includes pure manual control, which relies on the proficiency and feeling of the operator to control and reduce waste. This operation method is too dependent on the level of the operator. The second method is to set a convex point on the discharge side of the lower mold of the stamping equipment. After the sheet is stamped, a hollow position will be generated at the position where the workpiece is taken out. The inner wall of the hollow position is used to support the convex point to control the movement distance of the sheet each time. Although this is simple, the sheet needs to be lifted up to pass over the convex point every time it moves, which reduces the processing efficiency. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] Figures 1 to 3 An embodiment of the present invention is shown.

[0022] Example: A stamping auxiliary device with a positioning function comprises an operating table 1, a stamping part 2 is installed on the upper side of the operating table 1, a conveyor belt 3 is installed on the upper side of the operating table 1 on the right side of the stamping part 2 along the left-right direction, and a track plate 4 is installed behind the conveyor belt 3, a first movable seat 5 and a second movable seat 6 are installed on the left-right layout along the upper edge of the track plate 4, a pressure block 7 is installed on the first movable seat 5 for moving up and down above the conveyor belt 3, and an electric suction cup 8 is installed on the second movable seat 6 for moving up and down above the conveyor belt 3. When punching and blanking, the plate to be processed is placed on the conveyor belt 3, and the part to be punched and blanked is placed in the punching part 2. During the punching process, the plate is pressed and fixed on the conveyor belt 3 by the pressing block 7 to prevent the plate from shifting during the punching process. After the punching and blanking is completed, the plate is fixed by the electric suction cup 8. After being fixed, the pressing block 7 moves up, and then the electric suction cup 8 drives the plate to move a specific distance toward the punching part 2 under the drive of the second moving seat 6. After the movement is completed, the pressing block 7 moves down to press the plate on the conveyor belt 3, and the punching part 2 performs punching and blanking. With the cooperation of the pressing block 7 and the electric suction cup 8, the plate can move the same distance each time, so that continuous positioning can be performed during punching and blanking, thereby improving processing efficiency. The cooperation of the pressing block 7 and the electric suction cup 8 can use plates of various widths and lengths for punching, and the distance that the electric suction cup 8 moves each time can be adjusted at any time according to the size of the parts punched and blanked.

[0023] Two guide baffles 9 are arranged parallel and spaced in the left-right direction on the upper side of the conveyor belt 3. A pressure strip 10 is installed at one end of the conveyor belt 3 close to the punching part 2. A gap is left between the pressure strip 10 and the upper side of the conveyor belt 3. The two ends of the pressure strip 10 are respectively connected to the frames on both sides of the conveyor belt 3. By setting two guide baffles 9, the two guide baffles 9 can be attached to both sides of the plate during the conveying process so that the plate will not be offset. By setting the pressure strip 10, it is possible to prevent the plate from tilting during the conveying process, which may result in the plate being unable to be properly conveyed between the upper and lower punches of the punching part 2.

[0024] Two parallel first rails 11 are arranged on the front side of the track plate 4 along the left-right direction, and a rack 12 parallel to the first rails 11 is arranged on the rear side of the upper end of the track plate 4 along the left-right direction. The first moving seat 5 and the second moving seat 6 are both installed on the front side of the track plate 4, and are both connected to the two first rails 11 for left-right sliding. The upper end of the first moving seat 5 is installed with a first servo motor 13 on the rear side of the track plate 4, the output shaft of the first servo motor 13 is arranged downward, and the first gear 14 is connected to the transmission, and the first gear 14 is meshed with the rack 12; the upper end of the second moving seat 6 is installed with a second servo motor 15 on the rear side of the track plate 4, the output shaft of the second servo motor 15 is arranged downward, and the second gear 16 is connected to the transmission, and the first gear 14 is meshed with the rack 12. The second servo motor 15 is started to drive the second gear 16 to rotate, thereby driving the second moving seat 6 to move left and right along the front side of the track plate 4. And because the second servo motor 15 can accurately control the start and stop, it can control the distance of each movement to remain consistent, thereby improving the utilization rate of the plate. The first movable seat 5 does not need to move during the punching and stamping process, and needs to move to the right to assist the second movable seat 6 in loading the plate. After each punching and stamping is completed, the plate is pushed with the help of the electric suction cup 8, so that the stamped and bent plate can move away from the stamping part 2 with the workpiece of the stamping number. When moving out of the stamping part 2, the workpiece will fall out of the plate. It can be collected quickly.

[0025] The front side of the first moving seat 5 is vertically provided with a second rail bar 17, and the second rail bar 17 is provided with a first lifting plate 18 that slides up and down. The pressing block 7 is installed on the front side of the lower end of the first lifting plate 18, and the first moving seat 5 is provided with a first driving assembly for driving the first lifting plate 18 to move up and down; the front side of the second moving seat 6 is vertically provided with a third rail bar, and the third rail bar is provided with a second lifting plate 19 that slides up and down. The electric suction cup 8 is installed on the front side of the lower end of the second lifting plate 19, and the second moving seat 6 is provided with a second driving assembly for driving the second lifting plate 19 to move up and down. In this way, each time the plate is moved, the first lifting plate 18 is driven upward by the first driving assembly, so that the pressing block 7 is moved away from the upper side of the plate, so as to facilitate the electric suction cup 8 to push the plate to move. After the movement is completed, the first lifting plate 18 descends, driving the pressing block 7 to press the plate to prevent the plate from shifting during the stamping process. Each time the plate is moved, the second lifting plate 19 electric suction cup 8 needs to move up and down.

[0026] The first driving assembly includes a third servo motor 20, a mounting plate 21 and a screw rod 22. The mounting plate 21 is horizontally mounted on the front side of the upper end of the first moving seat 5. The mounting plate 21 is provided with a rotation hole that passes through the upper and lower sides. The third servo motor 20 is mounted on the upper side of the mounting plate 21. A bottom plate 23 is provided on the front side of the lower end of the mounting plate 21. The lower end of the screw rod 22 is rotatably arranged on the upper side of the bottom plate 23. The screw rod 22 is arranged parallel to the second guide rail. The output shaft of the third servo motor 20 passes through the rotation hole and is transmission-connected to the upper end of the screw rod 22. The screw rod 22 is threadedly matched with a first driving block 24, and the first lifting plate 18 is fixedly connected to the first driving block 24. The second driving assembly adopts the same driving mode and structure as the first driving assembly. When driving the first lifting plate 18 to move up and down, the third servo motor 20 is started to drive the screw rod 22 to rotate. When the screw rod 22 rotates, the first lifting plate 18 is restricted by the second guide rail 17 and will not rotate. Therefore, the first driving block 24 will only move up and down along the screw rod 22 when the screw rod 22 rotates, thereby driving the first lifting plate 18 to move up and down.

[0027] A first connecting plate 25 is horizontally arranged on the front side of the first lifting plate 18, and the pressing block 7 is installed on the lower side of the first connecting plate 25, and a rubber block is installed on the lower side of the pressing block 7; a second connecting plate 26 is horizontally arranged on the front side of the second lifting plate 19, and the electric suction cup 8 is installed on the lower side of the second connecting plate 26. By setting the first connecting plate 25, it is convenient to place the pressing block 7 above the plate, and the rubber block can avoid damage to the plate. The second connecting plate 26 can make the electric suction cup 8 be placed above the plate.

[0028] A magazine 27 is installed on the upper side of the operating table 1 at the right end of the conveyor belt 3. By setting the magazine 27, the plate to be processed can be stored in the magazine 27. During processing, the second movable seat 6 can be moved to the position of the magazine 27, and the plate can be sucked from the magazine 27 by the electric suction cup 8 and moved to the conveyor belt 3. The plate is placed on the conveyor belt 3 through the cooperation of the first movable seat 5 and moved toward the stamping part 2.

[0029] The bin box 27 is mounted on the upper side of the operating table 1 through the mounting bracket 28. The lower end of the mounting bracket 28 is connected to the upper side of the operating table 1. The upper end is provided with a fourth rail bar in the front-to-back direction. The lower side of the bin box 27 is connected to the fourth rail bar in a front-to-back sliding manner. By providing the mounting bracket 28 and the fourth rail bar, it is convenient to stack and arrange multiple groups of plates in the bin box 27. By moving the bin box 27 forward and backward, the group of plates to be processed can be moved to the bottom of the electric suction cup 8, which is convenient for taking out the materials.

[0030] The track plate 4 is mounted on the upper side of the operating table 1 through the support rods 29. By providing the support rods 29, the track plate 4 can be well supported.

[0031] Although the present invention is described herein with reference to a number of illustrative embodiments of the present invention, it will be appreciated that those skilled in the art may devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein.
