Description

Technical Field

[0001] This utility model relates to the field of CNC punching machine technology, specifically a device for automatically cleaning waste materials from a CNC punching machine. Background Technology

[0002] The main sources of scrap from CNC punching machines are scraps, chips, and defective products generated when metal sheets are cut or formed by dies during the stamping process. When the punching machine punches, blanks, or cuts, excess metal material separates from the workpiece, forming scrap. In addition, die wear or improper equipment adjustment may also lead to material waste or increased scrap. Scrap cleaning is an important part of CNC punching machine maintenance. If not cleaned in time, scrap may accumulate on the worktable or around the die, affecting processing accuracy or even damaging the die. Scrap may also get stuck in moving parts of the equipment, causing mechanical failures or safety hazards. At the same time, scrap accumulation will reduce production efficiency, increase downtime, and even affect product quality. Therefore, regularly cleaning scrap with a scrap cleaning device can not only extend the life of the equipment but also keep the working environment clean and ensure a smooth production process.

[0003] In the prior art, the CNC punch press with automatic waste removal proposed in CN217474536U uses a brush to clean the metal waste in the stamping groove and guides it into the receiving cavity for storage through the waste channel. However, for high-speed continuous stamping and stamping of high-hardness materials such as stainless steel and titanium alloys, coolant is usually used to cool the stamping groove, so the coolant can easily enter the receiving cavity along with the metal waste. Therefore, we have made an improvement and proposed a device for automatically cleaning waste from a CNC punch press. Utility Model Content

[0030] It also includes: a collection cylinder 9 that can be detachably installed inside the cylinder 3; and a second telescopic rod 16 that is rotatably installed inside the collection cylinder 9, one end of which is fixedly connected to the annular plate 15.

[0031] It also includes: a connecting plate 17 fixedly installed at the movable end of the second telescopic rod 16, the connecting plate 17 being slidably connected to the collecting cylinder 9; a threaded rod 13 rotatably installed on the collecting cylinder 9; and a first magnetic ring 12 slidably installed on the collecting cylinder 9, the connecting plate 17 containing a magnet block that cooperates with the first magnetic ring 12.

[0032] It also includes: a main gear 20 rotatably mounted on the collecting cylinder 9, the main gear 20 being fixedly connected to the second telescopic rod 16; an intermittent transmission gear set 21 mounted on the collecting cylinder 9, a belt 23 for transmission being installed between the intermittent transmission gear set 21 and the threaded rod 13, the intermittent transmission gear set 21 being meshed with the main gear 20; the intermittent transmission gear set 21 includes multiple complete gears and incomplete gears.

[0033] It also includes: a receiving plate 18 slidably installed inside the collecting cylinder 9; a spring 19 installed between the receiving plate 18 and the collecting cylinder 9; a second magnetic ring 10 slidably installed on the collecting cylinder 9, the receiving plate 18 containing a second magnet block that cooperates with the second magnetic ring 10; and an indicator rod 11 inserted into the second magnetic ring 10, the indicator rod 11 being slidably connected to the cover plate 4.

[0034] Working principle: After stamping, the hydraulic cylinder 1 extends, driving the push plate 2 to move towards one side of the cylinder 3. During the movement, the push plate 2 pushes the waste material and coolant in the stamping groove onto the guide plate 5, and moves along the guide plate 5 to the blocking plate 6. Then, the hydraulic cylinder 1 retracts, driving the push plate 2 back to its original position. During this process, the first telescopic rod 7 retracts downward, causing the blocking plate 6 to move downward. After the blocking plate 6 moves downward, the waste material and coolant fall onto the screen plate 8 and the annular plate 15, and the coolant can... The coolant flows from the sieve plate 8 to the lower end of the cylinder 3 (before operation, connect valve 14 to the filtration system first, then to the coolant supply system; the coolant can be recycled through valve 14 after it is below the cylinder 3, making it environmentally friendly). The main gear 20 rotates, driving the second telescopic rod 16 and the annular plate 15 to rotate synchronously, causing the waste on the annular plate 15 to rotate. Centrifugal force is used to throw off the coolant adhering to the waste, achieving separation of waste and coolant. Simultaneously, the main gear 20 rotates, controlling the first telescopic rod 7 to extend upwards, driving the blocking plate 6 to block the guide plate 5. The rotation of the main gear 20, through the intermittent transmission gear set 21, drives the threaded rod 13 to rotate intermittently. The rotation of the threaded rod 13 drives the first magnetic ring 12 and the connecting plate 17 to move up and down reciprocally. When the connecting plate 17 moves downwards, the second telescopic rod 16 retracts downwards, driving the annular plate 15 downwards, causing the waste on the annular plate 15 to fall into the collection cylinder 9. Since the annular plate 15 is rotating, centrifugal force can be used to remove the coolant adhering to the annular plate 16. All the waste on plate 5 is thrown onto the receiving plate 18 of the collecting cylinder 9 for collection. Then the connecting plate 17 moves upward, causing the second telescopic rod 16 to reset and the annular plate 15 to reset. As the amount of waste on the receiving plate 18 increases, the receiving plate 18 moves downward under the force of gravity. The downward movement of the receiving plate 18 causes the second magnetic ring 10 to move downward, which in turn causes the indicator rod 11 to move downward. The operator can intuitively understand the amount of waste stored in the collecting cylinder 9 through the indicator rod 11 so as to handle it in a timely manner.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
