[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] With the rapid development of automation technology today, designing an automatic material handling device using automatic control technology can completely overcome the difficulties in the background technology and greatly help safe production.

[0021] This utility model discloses an automatic material handling device for stamping sector-shaped pieces on a 160-ton punch press. A schematic diagram of the overall automatic material handling device is shown below. Figure 1 The diagrams for the automatic unwinding machine for rolled materials and the automatic winding machine for waste materials are not shown; only the feeding mechanism with the servo motor driving the rollers is shown.

[0022] Specifically, this utility model includes an X-direction guide rail bracket 1 connected to the two side columns 4 of the punch press, a slide 5 on the X-direction guide rail bracket 1, a Y-direction bracket 8 on one side of the slide 5, a Z-direction bracket 11 at the bottom of the Y-direction bracket 8, a moving guide rail 14 at the bottom of the Z-direction bracket 11, a Z-direction guide rail bracket 13 at the bottom of the moving guide rail 14, and a material suction cup 15 below the Z-direction guide rail bracket 13. A conveyor belt 21 is provided below one side of the Z-direction guide rail bracket 13. An upper die holder and an upper die are provided above the other side of the Z-direction guide rail bracket 13, and a lower die holder and a lower die are provided below the other side. The stamping strip material conveyed by the feeding roller passes through the space between the upper die and the lower die.

[0023] The Z-direction bracket 11 is equipped with a connected X-direction servo motor 3 and an X-direction running rack 2. A Y-direction servo motor 6 is provided on one side of the Z-direction bracket 11. A Y-direction transmission mechanism 7 (a gear and rack in the Y-direction) is connected to the Z-direction bracket 8 and the Z-direction bracket 11. A Z-direction servo motor 10 is provided on one side of the Y-direction bracket 8 of the Z-direction bracket 11. A Z-direction lead screw 12 is connected between the Z-direction bracket 11 and the Z-direction guide rail bracket 13. The Z-direction lead screw 12 can drive the Z-direction guide rail bracket 13 to move back and forth.

[0024] A crankshaft is connected above the upper mold base. One end of the crankshaft is connected to a flywheel and a motor, and the other end is connected to a cam controller via an angle encoder. A material handling conveyor belt 21 is connected to a material handling conveyor belt motor 20. The conveyor belt 21 is used to place the second sector piece 22, and the stamping strip can be placed on the first sector piece 16. The feed roller is connected to a feed servo motor.

[0025] The working process of a 160-ton punch press is as follows: When the motor is powered on, it drives the flywheel to rotate. The clutch actuates, driving the crankshaft connected to the flywheel to rotate. The crankshaft drives the punch to reciprocate through the connecting rod mechanism. When the crankshaft rotates 360 degrees, the punch completes one stroke, and when there is material, it punches out a piece.

[0026] The automatic feeding device must complete the feeding within one stroke of the punch. The feeding sequence can be controlled by a cam controller + PLC + touch screen + servo control system. The angle encoder used for angle detection is directly connected to the crankshaft (e.g., ...). Figure 1 The cam controller can generate multiple output signals at any angle during the crankshaft rotation of 360 degrees (corresponding to one complete stroke of the punch). The working range of multiple output signals can be set as needed. The automatic control system of the automatic material handling device completes the feeding and material handling actions based on these signals.

[0027] The automatic material handling device has three axes, named X-axis, Y-axis, and Z-axis respectively, such as... Figure 1 As shown. A set of signals related to the automatic feeding and unloading of materials by the automatic material handling device is as follows: Figure 2 The highest point of the punch stroke is the top dead center (corresponding to a cam angle of 0° or 360°, which is the same point), and the lowest point is the bottom dead center (corresponding to a cam angle of 180°).

[0028] Feeding (SQ1) refers to the process where, after the upper die stamping is completed, the punch rises from the bottom dead center to 225°, and the automatic coil feeder feeds the material according to the required size. Feeding must be completed before the punch descends to 135°. Retrieving (SQ2) refers to the process where, after the upper die stamping is completed, the punch rises from the bottom dead center to 270°, and the automatic retrieving device can enter between the upper and lower dies to retrieve the stamped sheet. Retrieving must be completed before the punch descends to 90°; otherwise, the automatic retrieving device will collide with the punch, and the automatic control system will consider this a safety malfunction, requiring an emergency stop. The engagement angles of SQ1 and SQ2 can be adjusted on the cam controller or touchscreen according to the actual situation.

[0029] The working process of the automatic material handling device is as follows:

[0030] I. Manual Adjustment

[0031] 1. Calculate the feeding length Amm based on the dimensions of the lamination and input it on the human-machine interface (HMI). During lamination, the feeding servo motor drives the feeding roller to complete the feeding. In automatic mode, feeding begins when the SQ1 signal of the cam is turned on and ends before it is turned off.

[0032] 2. Adjust position

[0033] 1) Adjust the slide block 5 controlled by the X-direction servo motor 3 so that the automatic material handling device can move left and right in the X direction, so that it stops at the position where the automatic material handling device can accurately pick up the punch.

[0034] 2) Adjust the material suction cups 15 on the automatic material handling device (three are shown, and can be configured as needed) so that they can pick up the stamped blanks when vacuuming and drop the blanks when compressed air is blown.

[0035] 3) Adjust the reciprocating distance of the Z-direction servo motor 10 so that when the Z-direction guide rail bracket 13 is at zero point, the punch picked up by the material suction cup 15 can just fall onto the conveyor belt 21. Move the Z-direction guide rail bracket 13 forward Zmm so that the material suction cup 15 on the Z-direction guide rail bracket 13 can just stop above the first sector piece 16.

[0036] 4) The Y-direction servo motor 6 controls the reciprocating movement distance in the Y direction so that when the Y direction is at zero, the material pick-up chuck 15 can just safely detach the punch from the lower die by Ymm; when it moves down by Ymm, the material pick-up chuck 15 can just press the punch, and when it moves to zero in the Z direction, it can accurately move the punch above the conveyor belt 21.

[0037] II. Automatic Operation

[0038] Automatic operation begins, conveyor belt 21 is powered on; Y-axis and Z-axis are at zero position; main motor rotates, clutch engages, flywheel drives crankshaft to rotate, crankshaft drives punch downward → stamping lower die (completing blank stamping) → (cycle point) punch moves upward to 275°, cam controller SQ2 switch is turned on → Z-direction guide rail bracket 13 begins to move Zmm above lower die stamping piece → automatic material handling device moves downward Ymm in Y direction, simultaneously material handling suction cup 15 draws vacuum, material handling suction cup 15 contacts and presses against the first sector piece 16, material handling suction cup 1... 5. Under vacuum conditions, the first sector piece 16 is held in place. The Y axis moves upward to zero point → the Z axis returns to zero point. During the Z axis return to zero point, SQ1 is activated, the feeding servo motor starts feeding Amm → the suction cup stops vacuuming and blows compressed air into the suction cup → the punch falls onto the conveyor belt 21 → the punch is conveyed out through the conveyor belt 21 for subsequent stacking processing → the punch moves through the top dead center, descends to 135°, SQ1 is disconnected, and the material picking is completed; descends to 270°, SQ2 is disconnected, and the feeding is completed → enter the cycle point to start the next cycle.
