Description

Technical Field

[0001] The present invention relates to the technical field of metal stamping, and particularly relates to a metal plate stamping and forming device and method. Background Art

[0002] Metal stamping is a manufacturing process that uses a metal stamping die or a series of metal stamping dies to form a metal sheet into a workpiece with three-dimensional dimensional shapes.

[0003] When metal is stamped, the metal plate is stamped by the upper die and the lower die to form a specified shape. During the stamping process, the upper die and the lower die are in direct contact with the metal part. Scratches will appear on the surface of the metal part during friction, and the metal part will also cause scratches on the upper die and the lower die. Therefore, a film is generally adhered to the metal. However, it still needs to be reprocessed after stamping. Another method is to isolate the metal plate from the die through two films. After stamping, the film will be damaged to a certain extent. Then, the used film is pulled away, and a new film is re-covered on it for another stamping. Although this stamping method does not require post-treatment of the metal plate, it is very wasteful of the film. Summary of the Invention

[0022] A metal plate stamping forming method, which is applicable to the metal plate stamping forming equipment described above, comprises the following steps:

[0023] S1: Install the film roll and pull the film under the suction nozzle;

[0024] S2: Then the stamping program is started through the controller, the controller opens the air nozzle, the air source draws air through the suction nozzle, the suction nozzle draws air to suck the film below, and then the controller controls the motor to drive the gear to rotate forward, so that the four suction nozzles pull the two films to move, and the film pulls the film roll to unload the material. The upper mold and the lower mold are separated by two layers of film. The moving plate stops moving after moving to half the distance, waiting for stamping, and then the metal plate is placed between the two films through the external loading equipment, and placed on the lower mold through the film;

[0025] S3: Then the controller controls the hydraulic cylinder to operate, and the hydraulic cylinder pushes the upper mold downward to punch the metal plate through the upper film. The metal plate is formed by the lower mold through the film. The two layers of film separate the metal plate from the upper mold and the lower mold.

[0026] S4: The external feeding equipment takes away the formed metal parts. At this time, the controller controls the motor to continue to drive the gear to rotate forward, pull the film to continue to move, pull away the film with slight damage after use, and pull the unused film between the upper mold and the lower mold, and then perform another stamping. During stamping, the controller controls the motor to drive the gear to reverse, the upper film limit plate moves to the upper part of the upper film, and the lower film limit plate moves to the upper part of the lower film. After the stamping is completed, the feeding equipment takes away the metal parts, and then the controller starts the motor to drive the gear to rotate forward, so that the moving plate that moves to the end of the reciprocating screw drives the U-shaped frame and the suction nozzle to pull the film back, and the moving plate moves to the end of the reciprocating screw and stops moving. At this time, the film wraps the film limit plate, and the two sections of stamped films overlap. Then the feeding equipment loads, and then the stamping forming mechanism stamps, and then the feeding equipment unloads;

[0027] S5: After the blanking is completed, start the motor to drive the gear to reverse, so that the moving plate two and the film limiting plate at the reciprocating thread end of the double-section reciprocating screw rod move back. Then start the motor to drive the gear to rotate forward. When the gear rotates forward, the moving plate one drives the U-shaped frame and the suction nozzle to move to one end of the thread tail. Then close the suction nozzle. The film without suction naturally droops downward. At the same time as closing, the moving plate one drives the suction nozzle to move to the thread tail. Then start the suction nozzle to suck the film at the thread tail position, and then pull it to the middle position of the reciprocating screw rod one. At this time, the controller starts the rodless cylinder to drive the laser cutter to move to one side and then move back. During the moving process, the laser cutter starts, and the laser passes through the middle of the U-shaped frame to cut the film, separating the unused film from the film used twice. Then close the suction nozzle that sucks the film stamped twice. The film vertically falls into the interior of the waste bin by gravity, then slides into the deep part of the waste bin along the sliding block, and then starts a new round of stamping through the feeding equipment.

[0028] Compared with the existing technology, the beneficial effects of the present invention are as follows:

[0029] 1. By installing a film recycling mechanism, the present invention overlaps two used films together. The two damaged films complement each other and are used again, making full use of the film, saving film resources and reducing production costs on the premise of protecting workpieces and molds;

[0030] 2. By installing a film end support mechanism to support one end of the overlapped film, a distance is maintained between the upper film and the lower film, which is convenient for feeding and blanking. Description of the Drawings

[0058] Example 2: Refer to Figures 2-5 : On the basis of Example 1, this example provides a method for stamping and forming a metal plate, which is applicable to the above-mentioned metal plate stamping and forming equipment, and includes the following steps:

[0059] S1: During initial installation, place the film end of the upper film reel 32 on the top of the upper separation rod 33 and below the four upper suction nozzles 410, and place the film end of the lower film reel 32 on the top of the lower separation rod 33 and below the four lower suction nozzles 410;

[0060] S2: Then the stamping program is started by the controller, the controller opens the air nozzle, the air source is sucked through the suction nozzle 410, the suction nozzle 410 sucks the film below, and then the controller controls the motor 61 to drive the gear 62 to rotate forward, the forward rotation of the gear 62 is satisfied with driving the one-way gear 1 418 to drive the shaft 2 416 to rotate, the shaft 2 416 drives the shaft 1 412 and the bevel gear 1 413 to rotate through the pulley 3 415 and the belt 3 417, the bevel gear 1 413 drives the bevel gear 2 414 and the reciprocating screw 1 42 connected thereto to rotate, and the reciprocating screw 1 414 is driven by the pulley 3 415 and the belt 3 417. 2 The other reciprocating screws 42 are driven to move synchronously by pulley 1 44, belt 1 45, pulley 2 46 and belt 2 47. The reciprocating screw 42 causes the moving plate 48 to drive the U-shaped frame 49 and the suction nozzle 410 to move. The four suction nozzles 410 pull the two films to move. The films pull the film roll 32 to discharge the film. The upper mold 22 and the lower mold 23 are separated by two layers of film. The moving plate 48 stops moving after moving to half the distance, waiting for stamping, and then the metal plate is placed between the two films through the external feeding equipment, and is placed on the lower mold 23 through the film.

[0061] S3: Then the controller controls the hydraulic cylinder 21 to operate, and the hydraulic cylinder 21 pushes the upper mold 22 downward to punch the metal plate through the upper film. The metal plate is formed by the lower mold 23 through the film. The two layers of film separate the metal plate from the upper mold 22 and the lower mold 23, ensuring the stamping effect while avoiding stamping scratches on the surface of the molded part during stamping.

[0062] S4: The external feeding device removes the formed metal parts. At this time, the controller controls the motor 61 to continue driving the gear 62 to rotate forward, pulling the film to continue moving, pulling away the film with slight damage after use, and pulling the unused film to between the upper die 22 and the lower die 23. Then, another stamping is performed. During stamping, the controller controls the motor 61 to drive the gear 62 to rotate in reverse. The reverse rotation of the gear 62 causes the one-way gear two 56 to drive the double-section reciprocating threaded rod 52 to rotate, so that the moving plate two 54 drives the film limiting plate 55 to move. The upper film limiting plate 55 moves above the upper film, and the lower film limiting plate 55 moves above the lower film. After stamping, the feeding device removes the metal parts. Then, the controller starts the motor 61 to drive the gear 62 to rotate forward, so that the moving plate one 48 moving to the end of the thread of the reciprocating screw one 42 drives the U-shaped frame 49 and the suction nozzle 410 to pull the film back. Because the height of the film limiting plate 55 is lower than the height of the suction nozzle 410, when the suction nozzle 410 pulls the film back, it moves from the top of the film limiting plate 55. The moving plate one 48 stops moving after moving to the end of the thread of the reciprocating screw one 42. At this time, the film wraps the film limiting plate 55, and the films after two stamping operations overlap. The film limiting plate 55 supports the other end of the film, creating a gap between the upper film and the lower film, which facilitates the feeding of the feeding device. Then, the feeding device feeds the material, then the stamping and forming mechanism 2 stamps, and then the feeding device discharges the material;

[0063] S5: After discharging, start the motor 61 to drive the gear 62 to rotate in reverse to move the moving plate two 54 and the film limiting plate 55 moving to the end of the reciprocating thread of the double-section reciprocating threaded rod 52 back. Then, start the motor 61 to drive the gear 62 to rotate forward. The forward rotation of the gear 62 causes the moving plate one 48 to drive the U-shaped frame 49 and the suction nozzle 410 to move to one end of the thread. Then, close the suction nozzle 410. The film without suction naturally droops downward. At the same time as closing, the moving plate one 48 drives the suction nozzle 410 to move to the end of the thread. Then, start the suction nozzle 410 to suck the film at the end of the thread position, and then pull it to the middle position of the reciprocating screw one 42. At this time, the controller starts the rodless cylinder 72 to drive the laser cutter 73 to move to one side and then move back. During the moving process, the laser cutter 73 is started, and the laser passes through the middle of the U-shaped frame 49 to cut the film, separating the unused film from the film used twice. Then, close the suction nozzle 410 that sucks the film stamped twice. The film vertically falls into the interior of the waste bin 11 by gravity, and then slides into the deep part of the waste bin 11 along the sliding block 14. Then, start a new round of stamping through the feeding of the feeding device.

[0064] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent replacements or changes, should be covered by the protection scope of the present invention.

8. A method for stamping a metal plate, which is applicable to the metal plate stamping equipment described in claim 7, characterized in that, The following steps are involved: S1: Install the film roll (32) and pull the film under the suction nozzle (410); S2: Then the stamping program is started through the controller, the controller opens the air nozzle, the air source is sucked through the suction nozzle (410), the suction nozzle (410) sucks the film located below, and then the controller controls the motor (61) to drive the gear (62) to rotate forward, so that the four suction nozzles (410) pull the two films to move, and the film pulls the film roll (32) to discharge the material, the upper mold (22) and the lower mold (23) are separated by two layers of film, and the moving plate (48) stops moving after moving to half the distance, waiting for stamping, and then the metal plate is placed between the two films through the external loading device, and is placed on the lower mold (23) through the film; S3: Then the controller controls the hydraulic cylinder (21) to operate, and the hydraulic cylinder (21) pushes the upper mold (22) to move downward to punch the metal plate through the upper film, and the lower part of the metal plate is formed by the lower mold (23) through the film, and the two layers of film separate the metal plate from the upper mold (22) and the lower mold (23); S4: The external loading equipment takes away the formed metal parts. At this time, the controller controls the motor (61) to continue to drive the gear (62) to rotate forward, pull the film to continue to move, pull away the film with slight damage after use, and let the unused film be pulled between the upper mold (22) and the lower mold (23), and then perform another punching. During punching, the controller controls the motor (61) to drive the gear (62) to rotate reversely, and the upper film limit plate (55) moves to the top of the upper film, and the lower film limit plate (55) moves to the top of the lower film. After the stamping is completed, the feeding device takes away the metal part, and then the controller starts the motor (61) to drive the gear (62) to rotate forward, so that the movable plate (48) that moves to the tail of the reciprocating screw (42) drives the U-shaped frame (49) and the suction nozzle (410) to pull the film back, and the movable plate (48) moves to the tail of the reciprocating screw (42) and stops moving. At this time, the film wraps the film limiting plate (55), and the two sections of the stamped film overlap each other, and then the feeding device loads the material, and then the stamping and forming mechanism (2) stamps, and then the feeding device unloads the material; S5: After unloading is completed, the motor (61) is started to drive the gear (62) to rotate in reverse, so that the movable plate 2 (54) and the film limiting plate (55) that move to the reciprocating threaded tail of the double-stage reciprocating threaded rod (52) move back, and then the motor (61) is started to drive the gear (62) to rotate forward. The forward rotation of the gear (62) causes the movable plate 1 (48) to drive the U-shaped frame (49) and the suction nozzle (410) to move to one end of the thread tail, and then the suction nozzle (410) is closed. Without the suction force, the film naturally droops downward. While closing, the movable plate 1 (48) drives the suction nozzle (410) to move to the thread tail, and then the suction nozzle (410) is started to suck the thread tail position. The film is then pulled to the middle position of the reciprocating screw (42). At this time, the controller starts the rodless cylinder (72) to drive the laser cutter (73) to move to one side and then move back. During the movement, the laser cutter (73) is started, and the laser passes through the middle of the U-shaped frame (49) to cut the film, so that the unused film is separated from the film that has been used twice. Then, the suction nozzle (410) that sucks the film that has been punched twice is closed, and the film falls vertically into the inside of the waste box (11) by gravity, and then slides into the depth of the waste box (11) along the sliding block (14), and then a new round of punching is started by loading the material through the feeding equipment.
