Description

Technical Field

[0001] The invention relates to the technical field of punching machine tools, and in particular to a punching machine tool for batch processing of mechanical parts. Background Art

[0002] A punch press is a stamping press. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that cannot be achieved by mechanical processing through various mold applications. Therefore, its use is becoming more and more extensive.

[0003] Stamping production is mainly for sheet metal. Through the mold, blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting and extrusion can be made, which are widely used in various fields. For example, the switches, sockets, cups, cupboards, plates, computer cases, and even missiles and aircraft we use... There are many accessories that can be produced by punching machines through molds.

[0004] During the stamping process, strong friction occurs between the workpiece and the die, resulting in friction lines on the surface of the workpiece. The die will also be affected, so a protective film is needed to cover the space between the upper die and the workpiece to reduce the friction lines caused by the direct contact between the workpiece and the upper die. However, after the upper die presses the workpiece with the protective film laid flat on top, the surface area of ​​the workpiece deforms in the die and increases, while the protective film laid flat on top is broken and damaged due to the extrusion and the increase in the workpiece area. The protective film in the die cannot completely wrap the deformed workpiece, so that the unprotected position of the workpiece still wears against the upper die, resulting in local friction lines.

[0043] Starting motor 1 21 drives gear 22 to reverse, and the reverse rotation of gear 22 satisfies the direction of rotation of one-way gear 2 49 to drive shaft 3 46 to rotate. The rotation of shaft 3 46 drives sleeve 2 42 to reverse, and the reverse rotation of sleeve 2 42 drives shaft 4 43 and slider 2 44 to rotate and drives the discharge barrel 45 to rotate, so that the unused protective film is discharged. After the protective film is discharged, it sags due to its own gravity. After the material is discharged to the specified length, motor 1 21 is turned off.

[0044] The material moving mechanism 5 is installed on the stamping and forming mechanism 1 and is used to cooperate with the protective film retaining mechanism 6 to retain the protective film at multiple stations;

[0045] The material moving mechanism 5 includes a second motor 54 which penetrates and is fixed on the side wall of the driving box 14. A reciprocating screw 51 is fixed to one end of the output shaft of the second motor 54. A moving plate 52 is sleeved on the external thread of the reciprocating screw 51. One side of the moving plate 52 is rotatably connected to the rotating shaft 43. The other end of the rotating shaft 43 is rotatably connected to a connecting plate 53. The connecting plate 53 is fixedly connected to the moving plate 52.

[0046] Start the second motor 54 to drive the reciprocating screw 51 to rotate so that the movable plate 52 moves backward to the silk tail of the reciprocating screw 51, and the movement of the movable plate 52 drives the connecting plate 53 to move. The movable plate 52 and the connecting plate 53 push the second rotating shaft 33, the first sliding block 34, the fourth rotating shaft 43 and the second sliding block 44 to move in the sleeve, so that the unloading cylinder 45 and the winding cylinder 35 drive the protective film 36 to move backward, and then the controller opens the suction cup 63 located at the left front, and the suction force of the suction cup 63 sucks the protective film 36 below, and then continues to move to the silk tail. The movable plate 52 moves to the other end of the silk tail, so that the protective film 36 moves forward, and when the movable plate 52 moves to the silk tail, it stops moving, and then opens the left rear suction cup 63, the left rear suction cup 63 sucks the protective film 36 below, and the purpose of the left and right translation is to make the protective film 36 between the left front suction cup 63 and the left rear suction cup 63 have a margin, and then move the movable plate 52 to the middle position of the reciprocating screw 51, and then start the motor 121 to continue to drive the gear 22 to reverse, so that the discharge barrel 45 continues to rotate to discharge the material. The purpose of discharging is to make a certain margin between the suction cup 63 of the next row and the suction cup 63 of the previous row after being sucked. The margin can make the protective film droop with the suction cup 63 as the center, so that the protective film inside the downward upper mold 12 is conical, and the conical protective film can be completely wrapped around the outside of the workpiece when the workpiece is stamped.

[0047] A controller is installed on the mounting frame 11 , and the controller is electrically connected to the driver of the upper mold 12 , the controller is electrically connected to the motor 1 21 and the motor 2 54 , and the controller is electrically connected to the vacuum pump.

[0048] Working principle:

[0049] The controller controls the upper mold driving mechanism to move the multi-station mold plate of the upper mold 12 downward, squeeze the workpiece placed on the workpiece placement table of the lower mold 13, then press the workpiece, and squeeze the workpiece placement table to move it and the workpiece downward. When moving downward, the multi-station mold boss of the lower mold cooperates with the upper mold to form a concave structure of the workpiece. During the deformation process, strong friction is generated between the workpiece and the mold, resulting in friction lines on the surface of the workpiece, and the mold will also be affected. Therefore, it is necessary to cover the upper mold 12 and the workpiece with a protective film to reduce the friction lines caused by the direct contact between the workpiece and the upper mold 12. However, after the protective film laid flat on the top presses the workpiece on the upper mold 12, the deformation surface area of ​​the workpiece increases, and the protective film laid flat on the top is squeezed and The area of ​​the workpiece becomes larger, so that the protective film is broken and damaged, and it is impossible to completely wrap the deformed workpiece, so that the unprotected position of the workpiece is still worn by the upper mold 12, resulting in local friction lines. At this time, the motor 1 21 is started to drive the gear 22 to reverse. The reversal of the gear 22 satisfies the direction of the one-way gear 2 49 to drive the shaft 3 46 to rotate. The rotation of the shaft 3 46 drives the sleeve 2 42 to reverse. The reversal of the sleeve 2 42 drives the shaft 4 43 and the slider 2 44 to rotate and drives the discharge barrel 45 to rotate, so that the unused protective film is discharged. After the discharge, the protective film sags due to its own gravity. After the discharge to the specified length, the motor 1 21 is turned off, and then the motor 2 54 is started to drive the reciprocating screw 51 to rotate so that the moving plate 52 moves backward to the tail of the reciprocating screw 51. The movement of the movable plate 52 drives the connecting plate 53 to move. The movable plate 52 and the connecting plate 53 push the rotating shaft 2 33, the slider 1 34, the rotating shaft 43 and the slider 2 44 to move in the sleeve, so that the unloading cylinder 45 and the winding cylinder 35 drive the protective film 36 to move backward, and then the controller opens the suction cup 63 located at the left front, and the suction force of the suction cup 63 sucks the protective film 36 below, and then continues to move to the moving plate 52 at the silk tail and moves toward the silk tail at the other end, so that the protective film 36 moves forward, and when the movable plate 52 moves to the silk tail, it stops moving, and then opens the left rear suction cup 63, and the left rear suction cup 63 sucks the protective film 36 below. The purpose of the left and right translation is to leave a margin for the protective film 36 between the left front suction cup 63 and the left rear suction cup 63, and then the movable plate 52 moves to the silk tail at the other end, so that the protective film 36 moves forward. The movable plate 52 moves to the middle position of the reciprocating screw 51, and then the motor 21 is started to continue to drive the gear 22 to reverse, so that the discharge barrel 45 continues to rotate to discharge the material. The purpose of discharging the material is to allow the suction cups 63 in the next row to have a certain margin between them and the suction cups 63 in the previous row after being sucked. The margin can make the protective film droop with the suction cups 63 as the center, so that the protective film inserted into the inner part of the downwardly moved upper mold 12 is conical. The conical protective film can be completely wrapped around the outside of the workpiece when the workpiece is stamped and formed, thereby solving the problem of the protective film being pulled, broken and damaged due to the small amount of the protective film in the upper mold 12, thereby avoiding the friction lines caused by the direct contact between the workpiece and the upper mold 12. After the stamping is completed, the motor 21 is started to drive the gear 22 to rotate forward.The positive rotation of gear 22 satisfies the one-way gear 1 310 to drive the rotation of shaft 1 37. The rotation of shaft 1 37 drives sleeve 1 32 to rotate through pulley 1 38 and belt 1 39. The rotation of sleeve 1 32 drives the rotation of shaft 2 33 and slider 1 34, thereby driving the winding drum 35 to rotate and wind the used protective film.

[0050] 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. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
