Technical Field

[0001] The utility model belongs to the technical field of numerical control punching machines, and more specifically relates to an automatic feeding device for numerical control punching machines. Background Art

[0002] A CNC punch press is an automated machine tool equipped with a program control system. It is primarily used for sheet metal processing and features high precision and a wide processing area. It logically processes and decodes programs specified by control codes or other symbolic instructions, thereby enabling the punch press to operate and process parts.

[0003] Currently, when loading a CNC punch press, workers use a forklift to place the sheet material on a rack. The rack then moves the sheet material to the loading area, where a robotic arm moves the sheet material to the CNC punch press for stamping. However, once the rack is used up, loading must be paused, and the rack removed for restocking. This interrupts the continuous loading and stamping process, slowing overall work efficiency.

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to 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.

[0037] Please also refer to Figure 1 、 Figure 2 and Figure 3 The automatic feeding device for a CNC punch press provided by the present invention will now be described. The automatic feeding device for a CNC punch press comprises a base 1, a loading platform 2, a feeding platform 3, and a feeding assembly. The loading platform 2 is fixedly mounted on the base 1. The feeding platform 3 is slidably mounted on the base 1. The feeding assembly comprises a first hydraulic cylinder 41 fixedly mounted on the base 1, a second hydraulic cylinder 42 fixedly mounted at the telescopic end of the first hydraulic cylinder 41, and a pusher plate 43 fixedly mounted at the telescopic end of the second hydraulic cylinder 42.

[0038] Among them, the first hydraulic cylinder 41 is set vertically, the second hydraulic cylinder 42 is set horizontally with the telescopic end facing the loading platform 2. When the feeding platform 3 moves to abut against the loading platform 2, the second hydraulic cylinder 42 rises and pushes the material plate onto the loading platform 2 through the pushing plate 43.

[0039] Specifically, the refilling platform 3 is moved away from the loading platform 2, and staff then use a forklift to place the sheet materials on the refilling platform 3 in advance. When the sheet materials on the loading platform 2 are nearly exhausted, the refilling platform 3 is moved to rest against the loading platform 2, and the first hydraulic cylinder 41 then lifts the second hydraulic cylinder 42 upward. The piston rod of the second hydraulic cylinder 42 extends, causing the push plate 43 to push the sheet materials on the refilling platform 3 toward the loading platform 2 until the sheet materials are completely moved onto the loading platform 2, thus achieving automatic refilling. During the refilling process, there is no need to move the loading platform 2, and there is no need to interrupt the loading and stamping processes, thus saving further time.

[0040] In some embodiments, see Figure 3 The automatic feeding device of the CNC punch press also includes a third hydraulic cylinder 31 fixedly arranged on the base 1, and the telescopic end of the third hydraulic cylinder 31 is connected to the feeding platform 3.

[0041] Specifically, the third hydraulic cylinder 31 is located below the feeding platform 3. The cylinder portion of the third hydraulic cylinder 31 is fixedly connected to the base 1, and the piston rod portion of the third hydraulic cylinder 31 is fixedly connected to the feeding platform 3. When feeding, the third hydraulic cylinder 31 is used to move the feeding platform 3 away from the loading area, making it easier for workers to use a forklift to load materials. This reduces the risk of collision with the CNC punch press during loading, thereby improving safety during operation.

[0042] In some embodiments, see Figure 1 and Figure 4 Rollers 32 are rotatably provided on both sides of the feeding platform 3 , and track grooves 11 are opened on both sides of the base 1 , in which the rollers 32 are rotatably provided.

[0043] Specifically, the rollers 32 provided on the feeding platform 3 can reduce the frictional resistance when the feeding platform 3 moves, making the feeding platform 3 move more smoothly on the base 1. At the same time, the track groove 11 provided on the base 1 guides the movement of the feeding platform 3, so that the feeding platform 3 remains straight when moving and avoids skewing.

[0044] In some embodiments, see Figure 1 、 Figure 2 and Figure 3 The automatic feeding device of the CNC punch press also includes a loading bracket 51, on which a vacuum suction cup manipulator 52 for grabbing the material plate is provided, and a driving component for driving the vacuum suction cup manipulator 52 to move is provided on the loading bracket 51.

[0045] The driving component can drive the vacuum suction cup manipulator 52 to move. After the vacuum suction cup manipulator 52 adsorbs the material sheet, the driving component drives the vacuum suction cup manipulator 52 to rise and move toward the CNC punch press. After moving to the discharge position of the CNC punch press, the vacuum suction cup manipulator 52 places the material sheet on the CNC punch press, thereby realizing automatic loading.

[0046] In some embodiments, see Figure 1 、 Figure 2 and Figure 3 The drive assembly includes a drive screw 61, a drive block 62, a guide rod 63 and a motor 64. The drive screw 61 is rotatably mounted on the loading bracket 51 and is arranged horizontally. The drive block 62 is threadedly connected to the drive screw 61. The guide rod 63 is fixedly mounted on the loading bracket 51, parallel to the drive screw 61, and slidably connected to the drive block 62. The motor 64 is fixedly mounted on the loading bracket 51, and the output shaft of the motor 64 is connected to the drive screw 61. The vacuum suction cup manipulator 52 is arranged on the drive block 62.

[0047] Specifically, the motor 64 drives the drive screw 61 to rotate. Under the restriction of the guide rod 63, when the drive screw 61 rotates, the drive block 62 can only move along the axis of the drive screw 61. Because the vacuum suction cup manipulator 52 is mounted on the drive block 62, the movement of the drive block 62 drives the vacuum suction cup manipulator 52 with it, thereby achieving the movement of the material sheet.

[0048] In some embodiments, see Figure 1 、 Figure 2 and Figure 3The driving assembly also includes a fourth hydraulic cylinder 65 arranged vertically, one end of the fourth hydraulic cylinder 65 is fixed to the driving block 62, and the other end is fixed to the vacuum suction cup manipulator 52.

[0049] Specifically, the cylinder body of the fourth hydraulic cylinder 65 is fixedly connected to the driving block 62, and the piston rod of the fourth hydraulic cylinder 65 is fixedly connected to the vacuum suction cup manipulator 52. The vacuum suction cup manipulator 52 is lifted and lowered by the extension and retraction of the piston rod of the fourth hydraulic cylinder 65, thereby driving the material plate to lift and lower.

[0050] During feeding, the piston rod of the fourth hydraulic cylinder 65 extends, causing the vacuum gripper 52 to descend and contact the sheet. After the vacuum gripper 52 has absorbed the sheet, the piston rod of the fourth hydraulic cylinder 65 retracts, lifting the sheet. The motor 64 drives the drive block 62 via the drive screw 61, which in turn moves the sheet toward the CNC punch press. When the sheet reaches the discharge position of the CNC punch press, the vacuum gripper 52 descends and places the sheet on the CNC punch press.

[0051] See Figure 1 and Figure 2 The automatic feeding device for a CNC punch press also includes a pressure sensor 71, a warning light 72, and a controller 73. The pressure sensor 71 is fixedly mounted on the base 1. The loading platform 2 is fixedly connected to the sensing end of the pressure sensor 71. The pressure sensor 71 and the warning light 72 are each electrically connected to the controller 73. The controller 73 receives the pressure signal from the pressure sensor 71. When the pressure signal reaches a threshold value when the material on the loading platform 2 decreases, the controller 73 sends a control signal to the warning light 72 to flash.

[0052] The sheet to be stamped is placed on loading platform 2, which is connected to the sensing end of pressure sensor 71, enabling it to detect the weight of the discharged sheet. As the weight of the sheet changes, the pressure signal detected by pressure sensor 71 also changes. When the sheet is nearing exhaustion, the pressure signal reaches a threshold. At this point, pressure sensor 71 transmits the pressure signal to controller 73, which in turn sends a first control signal to warning light 72, causing it to flash, prompting staff to refill.

[0053] Based on the above embodiments, please refer to Figure 1 and Figure 2 The automatic feeding device of the CNC punch press also includes a buzzer 74, which is electrically connected to the controller 73. When the warning light 72 flashes, the buzzer 74 sounds.

[0054] It should be understood that the specific installation locations of the warning light 72, the controller 73 and the buzzer 74 are not limited and can be installed in any location that does not interfere with normal operation and is convenient for staff to observe the operation.

[0055] The sound of the buzzer 74 and the flashing of the warning light 72 can serve as a reminder to the staff in terms of sound and light, making it easier for the staff to notice and thus having a better reminder effect.

[0056] In some embodiments, see Figure 1 A positioning plate 21 is fixedly provided on the loading platform 2.

[0057] Specifically, the positioning plate 21 is vertically arranged and extends upward. The positioning plate 21 plays a role in positioning the placement of the material sheet, so that each time the material is replenished, the material sheet will be moved to abut against the positioning plate 21. The material sheet abutting against the positioning plate 21 can also keep the material sheets neat.

[0058] In some embodiments, see Figure 1 、 Figure 2 and Figure 3 A supporting pad 33 is fixedly provided on the feeding table 3.

[0059] Specifically, the support pads 33 prop up the material sheet so that there is a certain gap between the material sheet and the feeding platform 3. When the staff uses a forklift to unload the material, after placing the material sheet on the support pads 33, the forklift's fork can be lowered until it is completely separated from the material sheet, so that the fork does not rub against the material sheet when it is withdrawn, thereby protecting the material sheet.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
