Another way is to fix the plate with a clamping assembly, and drive the punch assembly to move through a complex transmission mechanism to punch the four end corners of the plate respectively. The structure of this punching device is relatively complex, and the complex transmission mechanism makes it difficult to accurately control the displacement of the punch assembly, resulting in unstable processing accuracy of the plate.

[0024] Below, in conjunction with the accompanying drawings and specific embodiments, the present invention is further described:

[0025] like Figure 1 , 2As shown in Figures 3 and 4, a punching device for a plate of the present invention comprises a frame 10, a feeding assembly arranged at the front end of the frame 10, two first mounting seats 51, 52, and two second mounting seats 53, 54, wherein a punch assembly is arranged on the first mounting seat and the second mounting seat, and the specific structure of the punch assembly can be a structure commonly used in the prior art, which will not be described in detail here; wherein the frame 10 can be regarded as two parts connected front and back, wherein the front part thereof serves as a supporting part of the feeding assembly, and the rear part thereof serves as a mounting base part of the punching component, wherein a first longitudinal beam 30 is installed on one side of the rear part of the frame, and a second longitudinal beam 40 is installed on the other side, wherein the second longitudinal beam 40 is movably matched with the frame 10, specifically, a linear guide rail 12 is arranged on the frame 10, and the second longitudinal beam 40 is slidably mounted on the linear guide rail 12 through a slider, and a second driving assembly mounted on the frame 10 can be used to drive the second longitudinal beam 40 to move along the width direction of the frame 10, thereby changing the spacing between the second longitudinal beam 40 and the first longitudinal beam 30. The first mounting seat 51 is fixedly connected to the front end of the first longitudinal beam 30, the first mounting seat 52 is arranged opposite to the first mounting seat 51 and fixed to the front end of the second longitudinal beam 40, and the second mounting seat 53 and the second mounting seat 54 are respectively arranged at the rear ends of the first longitudinal beam 30 and the second longitudinal beam 40, and the two are also arranged opposite to each other. The feeding assembly includes a movable seat 20, two clamping members 21, a driving unit, and a first driving assembly. Among them, the movable seat 20 can be a beam extending along the width direction of the frame 10, the clamping member 21 is a clamping claw, the clamping member 21 slides with the movable seat 20 through the guide rail set on the movable seat 20, the extension direction of the guide rail is consistent with the width direction of the frame 10, the driving unit is used to drive the clamping member 21 to slide along the guide rail, and the first driving component is used to drive the movable seat 20 to move along the length direction of the frame 10. After clamping one end of the plate on the two clamping members 21, the first driving component drives the movable seat 20 to move from right front to rear, and moves the two end corners of the front end of the plate to the first mounting seat 51 and the first mounting seat 52 respectively. Specifically, the first drive assembly includes a first motor 61, a first transmission screw 62, and a first screw nut 63. The body of the first motor 61 is fixed on the frame 10. The extension direction of the first transmission screw 62 is consistent with the length direction of the frame 10, and one end thereof is connected to the rotating shaft of the first motor 61. The first screw nut 63 is sleeved on the first transmission screw 62 and fixedly connected to the movable seat 20. Of course, the first drive assembly is not limited to a screw transmission mechanism driven by a motor, it can also be other mechanisms that can realize linear motion. The above-mentioned drive unit for driving the clamping member 21 to move can also be a screw transmission mechanism driven by a motor or other linear motion mechanism.A limiting member 13 is also provided on the frame 10, and the limiting member 13 can be a limiting block protruding from the upper front surface of the frame 10, or can be a mechanism that can protrude from the upper front surface of the frame 10 when positioned under the drive of the limiting cylinder; the limiting member 13 can be a plurality of members arranged on the frame 10 and located on the same side as the first longitudinal beam 30; it is used to limit one side of the plate, that is, the driving unit drives the clamping member 21 to move in the direction close to the limiting member 13 until one side of the plate is against the limiting member 13, and then one side of the plate is positioned; the position of the limiting member 13 can be aligned with the punch assembly on the first longitudinal beam 30, at this time, it can be ensured that one side of the plate is facing the punch assembly on the first mounting seat 51 and the second mounting seat 53. In this embodiment, one end of the plate is positioned by the clamping member 21, that is, once the plate is clamped in place on the clamping member 21, the clamping member 21 is driven by the first driving assembly to move a certain distance so that one end of the plate is kept flush with the punch assembly on the first mounting seat 51 and the first mounting seat 52. The first longitudinal beam 30 is fixed on one side of the frame 10, and the second longitudinal beam 40 is movably mounted on the other side of the frame 10, that is, when the spacing between the second longitudinal beam 40 and the first longitudinal beam 30 changes, the spacing between the punch assemblies arranged on the first mounting seat 51 and the first mounting seat 52 also changes accordingly, so that the punch assembly can adapt to the width of the plate. The second drive assembly is the same as the first drive assembly mentioned above, and it also adopts a screw transmission mechanism. Specifically, the second drive assembly includes a second motor 71, a second transmission screw 72 and a second screw nut. The second transmission screw 72 is connected to the rotating shaft of the second motor 71, and the second screw nut is sleeved on the second transmission screw and fixed to the second longitudinal beam 40. After the above-mentioned positioning of one side and one end of the plate is completed, the second motor 71 is started to move the second longitudinal beam 40 in the direction close to the first longitudinal beam 30, and the punch assemblies on the first mounting seat 52 and the second mounting seat 54 are moved to the two end corners on the other side of the plate. The moving distance of the second longitudinal beam 40 can be controlled manually, or the width information of the plate can be input into the controller in advance. The controller determines the distance that the second longitudinal beam 40 should move according to the width of the plate and the position of the second longitudinal beam 40, thereby controlling the second motor 71. Of course, a first detection unit and a first control unit can also be set. The first detection unit is used to detect the position information of the other side of the plate. After detecting the position information of the other side of the plate, it sends it to the first control unit. The first control unit calculates the width of the plate to be punched through the position information of the other side of the plate and the position information of the limiter, thereby calculating the moving distance of the second longitudinal beam 40 through the width information of the plate, and then controlling the second motor accordingly. After positioning is completed, the four end corners of the plate can be punched by punching with four punch assemblies at one time.

[0026] Of course, in another embodiment, the above-mentioned first longitudinal beam 30 and second longitudinal beam 40 of the present invention are both fixed on the frame 10. In this case, after first positioning one side of the plate, the two end corners of one side of the plate are punched out by the punch assemblies on the two mounting seats on the first longitudinal beam 30, and then the driving unit is controlled by the controller according to the detected width information of the plate, so that the driving unit drives the clamping member to move a certain distance toward the second longitudinal beam 40, and then the other side of the plate is positioned, and then the two end corners of the other side of the plate are punched out by the punch assemblies on the two mounting seats on the second longitudinal beam 40, thereby completing the punching of the four end corners of the plate.

[0027] In the above embodiment, the spacing between the first mounting seat and the second mounting seat is kept fixed, that is, the second mounting seats 53 and 54 are respectively fixed to the rear ends of the first longitudinal beam 30 and the second longitudinal beam 40, that is, the above embodiment is suitable for the blanking processing of fixed length plates. In order to increase the scope of application of the present invention, in a preferred embodiment, the present invention slides the second mounting seat 53 and the second mounting seat 54 on the first longitudinal beam 30 and the second longitudinal beam 40, respectively. Taking the first longitudinal beam 30 as an example, a linear guide 31 extending along the length direction of the frame 10 and a third drive assembly are arranged on it, the second mounting seat 53 is slidably mounted on the linear guide 31, and the third drive assembly includes a third motor 81 mounted on the second mounting seat 53, a gear 82 mounted on the rotating shaft of the third motor 81, and a rack 83 meshed with the gear. The rack 83 is fixed on the first longitudinal beam 30. When the third motor 81 is started, the second mounting seat 53 can be driven to move along the length direction of the frame 10. Of course, the third drive assembly can also be a screw transmission mechanism like the above first drive assembly. A linear guide 41 and a third driving assembly are also fixed on the second longitudinal beam 40. The third motor 81 is used to drive the second mounting seats 53 and 54 to move, thereby driving the punch assembly thereon to align with the other end corner of the other end of the plate. In order to achieve this alignment, the present embodiment also includes a second detection unit and a second control unit. The second detection unit is used to detect the position information of the other end of the plate and send the position information to the second control unit. The second control unit calculates the distance that the second mounting seats 53 and 54 should move based on the position information of the other end of the plate and the position information of the clamp 21, thereby controlling the third motor 81 so that the punch assembly on the second mounting seats 53 and 54 faces the other end corner of the other end of the plate. Of course, it can also be the same as above, where the length information of the plate is pre-input into the controller, and the controller determines the distance that the second mounting seats 53 and 54 should move based on the length of the plate and the position of the clamp.

[0028] See also Figure 5As shown, the present invention delivers the plate 90 to the rear of the frame through the feeding assembly. When the plate 90 is clamped by the clamping member, and because the positions of the first mounting seats 51 and 52 are fixed, and the distance of each movement of the feeding assembly is also fixed, that is, the position of the left end of the plate 90 can be determined. After the clamping member is driven by the driving unit to move, the upper edge of the plate is pressed against the limiter. Since the setting position of the limiter is consistent with the positions of the two punch assemblies on the first longitudinal beam 30, the position of the upper edge of the plate can be determined; then the displacement of the second longitudinal beam 40 and the second mounting seats 53 and 54 is controlled by the first control unit and the second control unit respectively, the positioning of the four end corners of the plate can be completed. Then, the four end corners of the plate can be processed simultaneously.

[0029] It should be noted here that the first detection unit and the second detection unit of the present invention may be photoelectric sensors or other sensors that can accurately detect positions.

[0030] Compared with the prior art, the present invention can complete the punching of the four end corners without multiple positioning of the plate, thereby improving the efficiency and accuracy of plate punching. At the same time, it does not require a complex driving structure to drive the punch assembly to move horizontally, thereby simplifying the structure of the punching device and reducing equipment costs.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents, and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
