Description

Technical Field

[0001] The present invention relates to the technical field of metal stamping, and in particular to a metal plate stamping 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 metal sheets into three-dimensional shapes.

[0003] When metal is stamped, the upper and lower dies are used to stamp the metal plate to form a specified shape. During the stamping process, the upper and lower dies are in direct contact with the metal parts. The friction will cause scratches on the surface of the metal parts, and the metal parts will also scratch the upper and lower dies. Therefore, a layer of film is generally adhered to the metal, but it needs to be reprocessed after stamping. Another method is to isolate the metal plate from the mold with two films. After stamping, the film will be damaged to a certain extent, and then the used film will be pulled away, and a new film will be covered on it for another stamping. Although this stamping method does not require subsequent processing of the metal plate, it is very wasteful of film. Summary of the invention

[0014] A metal plate stamping forming method, which is applicable to the metal plate stamping forming equipment described above, comprises the following steps: S1: Install the film roll and pull the film under the suction nozzle; 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; 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. S4: The external feeding equipment takes away the formed metal parts.

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.

The forward rotation of the gear causes the moving plate 1 to drive the U-shaped frame and the suction nozzle to move to one end of the wire tail, and then the suction nozzle is closed. The film without suction naturally droops down. While closing, the moving plate 1 drives the suction nozzle to move to the wire tail, and then the suction nozzle is started to suck the film at the wire tail position, and then the film is pulled and moved to the middle position of the reciprocating screw 1. 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 movement, the laser cutter is started, 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, and then the suction nozzle that sucks the film that has been punched twice is closed. The film falls vertically into the inside of the waste box by gravity, and then slides into the depth of the waste box along the sliding block, and then a new round of punching is started through the loading equipment.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1.

[0033] Example 2: Reference Figure 2-5 : This embodiment provides a metal plate stamping forming method based on embodiment 1, which is applicable to the above-mentioned metal plate stamping forming equipment, and includes the following steps: S1: During the initial installation, the film end of the upper film roll 32 is placed on the top of the upper separation rod 33 and below the four upper suction nozzles 410, and the film end of the lower film roll 32 is placed on the top of the lower separation rod 33 and below the four lower suction nozzles 410; 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. 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. 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 pull the unused film between the upper mold 22 and the lower mold 23, and then perform another stamping. During stamping, the controller controls the motor 61 to drive the gear 62 to reverse. The reversal of the gear 62 satisfies the one-way gear 2 56 to drive the double-stage reciprocating threaded rod 52 to rotate, so that the moving plate 2 54 drives the film limiting plate 55 to move, and the upper film limiting plate 55 moves to the top of the upper film, and the lower film limiting plate 55 moves to the top of the lower film. After the stamping is completed, the loading equipment takes away the metal parts, and then the controller The starting motor 61 drives the gear 62 to rotate forward, so that the moving 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. Because the height of the film limiting plate 55 is lower than the height of the suction nozzle 410, the suction nozzle 410 moves from the top of the film limiting plate 55 when pulling the film back, and the moving plate 48 stops moving after moving to the tail of the reciprocating screw 42. At this time, the film wraps the film limiting plate 55, and the two sections of the stamped film overlap together. The film limiting plate 55 supports the other end of the film, so that there is a gap between the upper film and the lower film, which is convenient for the feeding device to feed, and then the feeding device feeds, and then the stamping forming mechanism 2 stamps, and then the feeding device unloads; S5: After unloading is completed, the motor 61 is started to drive the gear 62 to 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. The film without suction naturally droops down. At the same time as 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 film at the thread tail position, and then After pulling, it moves 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 used twice, and then the suction nozzle 410 that sucks the film that has been punched twice is closed. The film falls vertically into the inside of the waste box 11 due to gravity, and then slides into the deep of the waste box 11 along the sliding block 14, and then a new round of punching is started through the loading equipment.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.

10. A metal sheet stamping method, which is applicable to the metal sheet stamping equipment as claimed in claim 9, 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.
