Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plate punching equipment, in particular to a punching equipment capable of preventing waste from jumping out. Background Art
[0002] When punching a plate, a punching machine is generally required. In the prior art, a punching machine generally includes a driver (which can be a pneumatic cylinder, oil cylinder, or motor, etc.), the driver is connected to a connecting shaft, and a punching knife is installed at the end of the connecting shaft. During operation, the driver drives the connecting shaft to reciprocate and retract, thereby causing the punching knife to move back and forth. The plate is placed under the punching knife. When the punching knife moves down, it contacts the plate and punches it downward. A supporting plate for supporting the plate is generally provided below. The supporting plate has a leakage hole for the punching knife to pass through and for the punching waste (the punched part) to pass through. However, in the actual process, if it is necessary to perform multiple punching operations on the plate (i.e., process multiple holes), the waste material from the previous time may move upward with the ascending punching knife (the punching knife is a cylindrical structure, and the waste material will not have time to detach from the punching knife and will be carried upward), and then due to its own weight and its downward inertia, it will jump down onto the upper surface of the plate (i.e., jump out of the punching knife), affecting the normal progress of subsequent punching, thereby reducing processing efficiency (it is necessary to stop and clean up the waste material first, so it takes longer time and the efficiency becomes lower). Utility Model Content
[0003] In view of the deficiencies in the prior art, the present invention provides a punching device that prevents waste from jumping, which solves the problem in the prior art that waste may move up with the punching knife and then jump onto the plate surface, affecting the punching operation.
[0004] According to an embodiment of the present invention, a punching device for preventing waste from jumping includes:
[0005] The supporting plate is arranged horizontally and its two ends are fixedly connected to support plates so that it stands on the ground. The supporting plate is provided with a material leakage hole;
[0006] The first connecting shaft is vertically telescopically arranged just above the leakage hole and a punching knife is connected to its lower end. The punching knife is vertically arranged in a cylindrical shape and a pair of depressions are provided on the lower edge of the inner wall of the lower end;
[0007] The lifting plate is lifted and arranged above the supporting plate and is provided with a guide hole. The first connecting shaft slides through the guide hole and the punching knife can reciprocate in and below the guide hole.
[0008] A mounting arm is fixedly connected to one side of the supporting plate, which extends upward and has a mounting plate fixedly connected to its upper end. A first driver connected to the first connecting shaft and driving the first connecting shaft to extend and retract is also installed on the mounting plate. A second driver that drives the lifting plate to rise and fall is also installed on the mounting plate.
[0009] In the above embodiment, a pair of depressions are provided on the inner edge of the punching knife, and a pair of protrusions are correspondingly formed where waste is formed after punching. In this way, the depressions and protrusions are engaged with each other so that the waste is not easily separated from the punching knife. After multiple punchings, the multiple wastes formed will accumulate upward in the punching knife and can then be cleaned centrally. They will not fall onto the plate during the punching process, thus solving the problem in the prior art that the waste may move upward with the punching knife and then jump onto the plate surface, affecting the punching operation.
[0010] Furthermore, a vertically extending sliding groove is recessed in an end surface of one end of the lifting plate, and a guide bar slidably connected to the sliding groove is fixedly connected to the mounting plate.
[0011] Furthermore, the sliding grooves and the guide bars are two pairs that cooperate with each other.
[0012] Furthermore, a second connecting shaft is fixedly connected to the lifting plate, and the second connecting shaft is also connected to the second driver.
[0013] Furthermore, a material receiving trough located below the material leakage hole is fixedly connected below the material supporting plate.
[0014] Furthermore, a concave arc-shaped opening is provided on one side of the material receiving trough, and connecting plates are fixedly connected to both sides of the arc-shaped opening, and the two connecting plates are fixedly connected to the material supporting plates respectively.
[0015] Furthermore, the depression is a strip-shaped arc structure.
[0016] Furthermore, the guide hole includes a sliding section located above and in sliding contact with the first connecting shaft, and an accommodating section located below. The inner diameter of the accommodating section is larger than the first connecting shaft, and the punching knife reciprocates inside and outside the accommodating section.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] A pair of depressions are provided on the inner wall of the punching knife, so that corresponding protrusions are formed on the waste material formed by punching. In this way, the depressions and the protrusions are engaged with each other, so that the waste material is not easily separated from the punching knife. After multiple punchings, the multiple waste materials formed will accumulate upward in the punching knife and can then be cleaned centrally. They will not fall onto the plate during the punching process. Therefore, the problem in the prior art that the waste material may move up with the punching knife and then jump onto the plate surface, affecting the punching operation, is solved.

[0026] like Figure 1-3 As shown, this embodiment provides a punching device for preventing waste from jumping, which includes:
[0027] The supporting plate 1 is arranged horizontally and fixedly connected to support plates 2 at both ends so that it stands on the ground. A material leakage hole 3 is opened on the supporting plate 1;
[0028] The first connecting shaft 4 is vertically telescopically arranged just above the leakage hole 3 and a punching knife 5 is connected to its lower end. The punching knife 5 is vertically arranged in a cylindrical shape and a pair of recesses 6 are provided on the lower edge of the inner wall of the lower end;
[0029] The lifting plate 7 is lifted and arranged above the supporting plate 1 and is provided with a guide hole 8. The first connecting shaft 4 slides through the guide hole 8 and the punching knife 5 can reciprocate in and below the guide hole 8.
[0030] A mounting arm 9 is also fixedly connected to one side of the support plate 1, and the mounting arm 9 extends upward and a mounting plate 10 is also fixedly connected to its upper end. A first driver 11 connected to the first connecting shaft 4 for driving the first connecting shaft 4 to extend and retract is also installed on the mounting plate 10. A second driver 12 for driving the lifting plate 7 to rise and fall is also installed on the mounting plate 10.
[0031] In the above embodiment, a pair of recesses 6 are provided on the inner edge of the punching knife 5, and a pair of protrusions will be formed correspondingly when waste is formed after punching, so that the recesses 6 and the protrusions are engaged with each other so that the waste is not easy to be separated from the punching knife 5. After multiple punchings, the waste formed will accumulate upward in the punching knife 5 and then be cleaned up centrally. During the punching process, it will not jump onto the plate 20, thereby solving the problem in the prior art that the waste may move up with the punching knife 5 and then jump onto the upper surface of the plate 20 to affect the punching operation; the connection between the punching knife 5 and the first connecting shaft 4 is similar to that in the prior art, and both are detachable. When disassembling, the first drive 11 is operated so that the lower end of the punching knife 5 is located below the material support plate 1, and then it can be disassembled through the part located below, and then the waste inside is cleaned. After reinstallation, subsequent punching can be performed again; in more detail, the recess 6 in this scheme can also be a strip-shaped arc structure, and the two recesses 6 have the same rotation direction and extend along the length direction of the punching knife 5, so that the product The raw waste is rotated to a certain extent in the punching knife 5 (it is forced to rotate accordingly under the guidance of the recess 6), which makes it less likely to fall out of the punching knife 5. When cleaning, it can be removed for cleaning, or the punching knife 5 can be knocked under the supporting plate 1 to make the waste fall downward (especially, the arc of the recess 6 is very small, which only makes the waste rotate slightly, so the knocking can also make the waste fall downward); in order to facilitate the collection of waste, a support plate 1 is fixedly connected to the bottom below the leakage hole 3. The receiving trough 13 and the leakage hole 3 have a large inner diameter, which can smoothly allow the punching knife 5 to pass through, and there is also a large gap. If waste falls out from under the plate 20, it will smoothly enter the leakage hole 3 and then fall into the stirring trough. A concave arc-shaped opening 14 is provided on one side of the receiving trough 13, and connecting plates 15 are fixedly connected on both sides of the arc-shaped opening 14, and the two connecting plates 15 are respectively fixedly connected to the supporting plate 1. The arc-shaped opening 14 can make it more convenient to remove waste, and the punching knife 5 can be disassembled and installed and the waste can be cleaned.
[0032] like Figure 1-3As shown, in this scheme, a lifting plate 7 is also provided, and the distance between the lifting plate 7 and the supporting plate 1 can be adjusted. During processing, the lifting plate 7 can be made closer to the plate 20, close to the upper plate surface of the plate 20, to ensure that the waste will not directly fall onto the plate 20, and there is also a gap between the plate 20 and the lifting plate 7, so that the position of the plate 20 can be adjusted. When the plate 20 is put in, the lifting plate 7 can be raised to a higher position, so that the gap below the lifting plate 7 is larger, which is convenient for operation. At the same time, the lifting plate 7 also provides a vertical guide for the first connecting shaft 4 (achieved by the provided guide hole 8), so that the first connecting shaft 4 runs more smoothly; in more detail, The recess 6 at one end surface of the lifting plate 7 is provided with a vertically extending sliding groove, and a guide bar 16 slidably connected to the sliding groove is fixedly connected to the mounting plate 10. The guide bar 16 and the sliding groove can also be a pair that cooperates with each other, so that the lifting plate 7 can run more smoothly. In more detail, a second connecting shaft 17 is fixedly connected to the lifting plate 7, and the second connecting shaft 17 is also connected to the second driver 12, so that the second driver 12 drives the lifting plate 7; the first driver 11 and the second driver 12 are similar, and both can use cylinders, oil cylinders and other equipment similar to the prior art, but they drive the punching knife 5 and the lifting plate 7 separately and operate independently of each other.
[0033] like Figure 1 、 3 As shown, in a more detailed exemplary scheme, the guide hole 8 includes a sliding section 18 located above and in sliding contact with the first connecting shaft 4, and a receiving section 19 located below. The inner diameter of the receiving section 19 is larger than the first connecting shaft 4. The punching knife 5 reciprocates inside and outside the receiving section 19, and the sliding section 18 is in sliding contact with the first connecting shaft 4, thereby realizing a guiding effect. The receiving section 19 is larger, allowing the punching knife 5 to enter as a whole without contacting the punching knife 5, thereby avoiding collision or accidental jamming.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
