Description

Technical Field

[0002] Punching machine, as a kind of pressure processing equipment, can exert pressure on the material through the die, so as to realize the deformation of the material such as punching, bending, stretching, etc. to achieve the desired shape and size.

[0003] Through the punching die, the punch press can accurately punch out the product of the required shape from the product to be processed. The waste generated during the punch processing is generally discharged from the funnel at the bottom of the punch. The waste is easy to clog in the funnel and needs to be sucked up by a waste suction machine and collected in the waste box. The existing waste suction machine maintains a vacuum state during the suction process. When in use, the waste of the punch press is sucked into the waste hopper under the action of the fan, and the waste falls into the waste box. The punch press needs to be shut down, otherwise the waste box cannot be taken out under the vacuum state. After the shutdown, the waste box is manually dragged out, and the waste box is lifted to the waste dumping position and then bagged. Not only does the frequent replacement of waste boxes consume manpower, but it also causes the punch press to shut down and affects the punch press processing and production.

DETAILED DESCRIPTION

[0020] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0021] like Figure 1-3As shown, an automatic waste suction device includes a casing 1, a sealed box 3 connected to the casing 1, a vacuum fan 2 fixedly arranged on the top of the sealed box 3, a suction pipe 4 running through the casing 1 and connected to the feed port of the sealed box 3, and a vacuum pipe 5 connected to the air outlet of the sealed box 3 and the air inlet of the vacuum fan 2. The sealed box 3 has two sealed discharge valves, which cooperate to ensure that the sealed box 3 can continue to be vacuumed when discharging waste.

[0022] When the automatic waste suction device is in use, the vacuum fan 2 continuously draws a vacuum on the sealed box 3 to provide suction for the suction pipe 4 so as to suck the waste to the punch press. After a certain amount of waste is collected, a sealed discharge valve is opened to allow the waste to fall into the next sealed discharge valve of the sealed box 3 and accumulate. At this time, the sealed box 3 can still continue to draw a vacuum to maintain suction, and then close a sealed discharge valve and open the next sealed discharge valve to discharge the accumulated waste from the sealed box 3. In actual use, a ton bag is set under the sealed box 3 to collect a large amount of waste for a long time and then the ton bag can be directly transferred and replaced by a forklift. There is no need to frequently stop the punch press to take out the waste box, which is beneficial to improving the processing efficiency of the punch press.

[0023] Furthermore, the sealed box body 3 includes a box body 31, a partition 32 sealed in the middle of the box body 31, a breathable separation tank body 33 connected to the top of the partition 32 and connected to the suction pipe 4, a first discharge hopper 34 connected to the bottom of the partition 32 and connected to the breathable separation tank body 33, a first sealed discharge valve 35 connected to the discharge port of the first discharge hopper 34, a second discharge hopper 36 connected to the bottom of the box body 31, and a second sealed discharge valve 37 connected to the discharge port of the second discharge hopper 36. The partition 32 is used to divide the box body 31 into a first closed space 6 and a second closed space 7. The breathable separation tank body 33, the first closed space 6 and the vacuum pipe 5 are connected in sequence. Specifically, the vacuum fan 2 continuously evacuates the first closed space 6 and the air-permeable separation tank 33 of the sealed box 3 through the vacuum pipe 5, and provides suction for the suction pipe 4, so as to suck the waste material from the punch press. The air and waste material are separated in the air-permeable separation tank 33, and the waste material falls into the first discharge hopper 34. After a certain amount of waste material is collected, the first sealed discharge valve 35 is opened, so that the waste material falls into the second discharge hopper 36 through the second closed space 7 of the sealed box 3 for accumulation. At this time, the sealed box 3 can still continue to evacuate and maintain suction, and then the first sealed discharge valve 35 is closed, and the second sealed discharge valve 37 is opened, so that the accumulated waste material is discharged from the second discharge hopper 36. In actual use, a ton bag is set under the sealed box 3, so that a large amount of waste material can be collected for a long time, and then the ton bag can be directly transferred and replaced by a forklift, without the need for the punch press to frequently stop the machine to take the waste box, which is conducive to improving the processing efficiency of the punch press. Furthermore, the sealed box 3 also includes a sealed maintenance door 38 hinged on the side of the box body 31.

[0024] Furthermore, a ventilation opening 8 is provided on the side of the ventilation separation tank body 33 , and a ventilation net 9 is fixedly connected to the ventilation opening 8 of the ventilation separation tank body 33 , which helps to prevent waste from entering the first closed space 6 through the ventilation opening 8 of the ventilation separation tank body 33 .

[0025] Furthermore, the air inlet of the vacuum fan 2 is provided with an air inlet pipe 10 connected with the vacuum pipe 5, and the air inlet pipe 10 is provided with a fan pressure relief valve 11, which is beneficial to protecting the vacuum fan 2 and improving system stability and preventing pressure fluctuations.
