[0032] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention.

[0033] refer to Figures 1 to 4 The metal plate punching equipment of the present invention includes a frame 100, a workbench 110, a positioning frame 300, a clamping device and a driving device 200.

[0034] The workbench 110 is mounted on the frame 100. The positioning frame 300 is used to position the metal sheet, and the workbench 110 is used to support the positioning frame 300. The clamping device is used to clamp the metal sheet on the positioning frame 300. The punching device and the driving device 200 are both mounted on the frame 100. The output end of the driving device 200 is connected to the positioning frame 300 and the clamping device. The driving device 200 is used to drive the positioning frame 300 and the clamping device to move horizontally on the workbench 110, so that the punching device can punch the metal sheet on the positioning frame 300.

[0035] The workbench 110 is connected to the frame 100 and supports a positioning frame 300 for positioning the metal plate, allowing the positioning frame 300 to move smoothly and preventing deformation. A drive device 200 is connected to the frame 100. The output end of the drive device 200 is connected to both the positioning frame 300 and the clamping device, enabling the drive device 200 to drive the positioning frame 300 and the clamping device to move horizontally on the workbench 110. In the present embodiment, the horizontal direction refers to the left-right direction and the front-back direction, i.e., a direction perpendicular to the up-down direction.

[0036] It is understandable that when it is necessary to punch out multiple workpieces on a metal plate, the operator can place the metal plate to be punched on the positioning frame 300 so that the metal plate can be positioned. After the metal plate is positioned, the operator controls the clamping device to start, and the clamping device clamps the metal plate on the positioning frame 300, so that the metal plate is fixed on the positioning frame 300, thereby preventing the metal plate from sliding off the positioning frame 300. After the metal plate is fixed, the driving device 200 drives the positioning frame 300 and the clamping device to move horizontally along a predetermined path on the workbench 110, so that the metal plate can be moved to the punching device, and then the punching device can punch the metal plate on the positioning frame 300 to complete the punching of the metal plate. After the metal plate is punched, the driving device 200 drives the positioning frame 300 and the clamping device to reset, and the clamping device releases the metal plate on the positioning frame 300. The operator can then remove the metal plate that has been punched from the positioning frame 300 for the next punching. The positioning frame 300 plays a positioning role for the metal plate. The operator only needs to place the metal plate to be punched on the positioning frame 300. There is no need to repeatedly adjust the position of the metal plate to quickly complete the positioning of the metal plate, which saves the operator's time in adjusting the position of the metal plate, and is conducive to improving the punching efficiency of the metal plate.

[0037] It should be explained that in the embodiment of the present utility model, punching refers to the driving device 200 driving the positioning frame 300 and the clamping device to move horizontally along a predetermined path on the workbench 110, so that the metal plate can move relative to the punching device according to the predetermined path, and then the punching device can punch out a hole or contour of a specific shape on the metal plate to obtain a corresponding workpiece.

[0038] In an embodiment of the present invention, the punching device includes a hydraulic assembly, a die, and a punch. The die and the hydraulic assembly are arranged on a frame 100. The output end of the hydraulic assembly is connected to the punch. The gap between the die and the punch is used to allow the positioning frame 300 and the metal plate on the positioning frame 300 to pass through. The hydraulic assembly is used to drive the punch to rise and fall. The die and the punch are used in conjunction with each other. The die has a hole corresponding to the punch. The shape of the hole is consistent with the edge shape of the workpiece and is used to receive the cutting action of the punch, so that the punch can complete the punching of the metal plate. The punching device is a common cutting device and will not be further described here.

[0039] In an embodiment of the present invention, the driving device 200 is a common device for driving objects to move. The driving device 200 can drive the mounting plate 210 to move in the left and right directions and the front and back directions, so that the clamping device, the positioning frame 300 and the metal plate on the positioning frame 300 can move in the horizontal direction.

[0040] refer to Figure 3 and Figure 4 , a positioning groove 310 is provided on the positioning frame 300, and the positioning groove 310 is used to accommodate the metal plate, and the inner wall of the positioning groove 310 can abut against the metal plate. It is understandable that when the metal plate needs to be punched, the operator can place the metal plate in the positioning groove 310 on the positioning frame 300, and the inner wall of the positioning groove 310 can abut against the metal plate, which can play a positioning role on the metal plate. As an embodiment of the present invention, a hand buckle groove is provided on the positioning frame 300, and the hand buckle groove is connected to the positioning groove 310. It is understandable that the operator can put his hand into the hand buckle groove so that the operator can take the metal plate out of the positioning groove 310. As an embodiment of the present invention, a plurality of reinforcing rods are provided on the positioning frame 300, and the position of the reinforcing rods avoids the punching position of the metal plate. The reinforcing rods can enhance the structural strength of the positioning frame 300.

[0041] refer to Figure 2 and Figure 4 The metal sheet punching device further includes a mounting plate 210 connected to the output end of the driving device 200. The positioning frame 300 is disposed on the mounting plate 210. The clamping device includes two clamping assemblies 410, both of which are disposed on the mounting plate 210 and are used to clamp the metal sheet on the positioning frame 300. Specifically, the positioning frame 300 includes a front rod, a rear rod, and a left rod. The front rod and the rear rod are both parallel to the left-right direction, and the left rod is parallel to the front-back direction. The front rod is disposed in front of the rear rod. One end of each of the front rod and the rear rod is connected to the mounting plate 210, and the other ends of the front rod and the rear rod are connected via the left rod.

[0042] refer to Figure 4The clamping assembly 410 includes a lower clamping plate 411, an upper clamping plate 412, and a lifting drive 413. The lower clamping plate 411 and the lifting drive 413 are both arranged on the mounting plate 210. The lower clamping plate 411 is arranged in the area surrounded by the positioning frame 300. The gap between the lower clamping plate 411 and the upper clamping plate 412 is used to allow the metal plate to extend into. The lifting drive 413 can drive the upper clamping plate 412 to approach the lower clamping plate 411 so that the upper clamping plate 412 and the lower clamping plate 411 clamp the metal plate. It is understandable that when the metal plate needs to be punched, the lifting drive 413 drives the upper clamping plate 412 to rise, thereby increasing the gap between the upper clamping plate 412 and the lower clamping plate 411. The operator can then place the metal plate between the upper clamping plate 412 and the lower clamping plate 411 and place the metal plate into the positioning slot 310 on the positioning frame 300. Then, the lifting drive member 413 drives the upper clamping plate 412 to descend and approach the lower clamping plate 411 , so that the upper clamping plate 412 and the lower clamping plate 411 clamp the metal plate.

[0043] As one embodiment of the present invention, flexible pads are provided on both sides of the lower and upper clamping plates 411, 412 that are adjacent to each other. The lower and upper clamping plates 411, 412 each clamp a metal plate via the flexible pads. It is understood that the flexible pads are provided on the side of the upper clamping plate 412 that is adjacent to the lower clamping plate 411, and the flexible pads are provided on the side of the lower clamping plate 411 that is adjacent to the upper clamping plate 412. These pads can increase the friction between the upper and lower clamping plates 412, 411, and the metal plate, thereby improving the clamping effect of the upper and lower clamping plates 412, 411. Furthermore, the flexible pads can prevent the upper and lower clamping plates 412, 411 from damaging the metal plate.

[0044] refer to Figure 4 The clamping assembly 410 further includes a stopper 414, one end of which is connected to the mounting plate 210, and a lower clamping plate 411 is disposed on the other end of the stopper 414. The stopper 414 is disposed within the area enclosed by the positioning frame 300. The other end of the stopper 414 is configured to abut against the metal plate. The stopper 414 is formed with an escape groove 415, which is configured to allow the upper clamping plate 412 to extend therein. It is understood that the other end of the stopper 414 can abut against the metal plate, i.e., the other end of the stopper 414 serves to position the metal plate. Specifically, the front, rear, and left rods can respectively abut the front, rear, and left ends of the metal plate. Specifically, the front, rear, and left inner walls of the positioning slot 310 can abut the front, rear, and left ends of the metal plate, and the stopper 414 can abut the right end of the metal plate. This allows the metal plate to be fully positioned horizontally, thereby facilitating the punching accuracy of the punching device. Furthermore, after the upper clamping plate 412 is lowered, it can extend into the avoidance groove 415 on the stopper 414, making the structure of the clamping assembly 410 more compact.

[0045] refer to Figure 1and Figure 2 The metal sheet punching equipment also includes a brush assembly 120, which is disposed on the workbench 110 and is used to support the positioning frame 300. It is understood that the workbench 110 can support the positioning frame 300 and the metal sheet on it via the brush assembly 120. The brush assembly 120 can prevent the positioning frame 300 and the metal sheet from being scratched or damaged during movement, while also reducing the friction between the positioning frame 300 and the workbench 110, ensuring smooth sliding of the positioning frame 300 and the metal sheet. The brush assembly 120 can also help remove material residue from the positioning frame 300 and the metal sheet, keeping them clean.

[0046] As an embodiment of the present invention, the metal sheet punching equipment further includes an air jet device (not shown in the figure) that is configured to eject air from top to bottom to remove slag from the metal sheet. It should be noted that during the punching process, some of the metal material on the metal sheet will be cut off and fall off, forming slag, which will fall onto the surface of the metal sheet. Specifically, the air jet device includes a bracket and multiple air jet heads. The bracket is mounted on the workbench 110, and the multiple air jet heads are mounted on the bracket. The multiple air jet heads are configured to eject air from top to bottom, and the bottom of the bracket allows the metal sheet to pass through. It is understood that after the metal sheet is punched, when the operator removes it from the positioning frame 300, the metal sheet can pass through the bottom of the bracket, allowing the air jets from the multiple air jet heads to blow away the slag on the metal sheet, ensuring that the metal sheet remains clean and facilitates subsequent processing operations on the metal sheet. As an embodiment of the present invention, the air jet device further includes an air pump, the output end of which is connected to the multiple air jet heads. The air jet device is a common device and will not be further described here.
