[0028] Embodiment 1:

[0029] See also Figure 1-4 The utility model describes the above technical solution in detail through the following embodiments:

[0030] A road traffic sign punching machine, comprising:

[0031] The stamping assembly 1 comprises a workbench 11, a hydraulic cylinder 15 is installed on the top surface of the workbench 11 through a stamping frame 14, a punching head 16 is threadedly installed on the top of the piston rod of the hydraulic cylinder 15, a mold 13 is arranged just below the punching head 16, and the hydraulic cylinder 15 is used to drive the punching head 16 to move.

[0032] The die 13 is fixed on the top surface of the workbench 11 by clamping or bolting. The piston rod of the hydraulic cylinder 15 is controlled to work, thereby driving the punching head 16 to move, thereby controlling the distance between the punching head 16 and the die 13.

[0033] A discharge groove 12 is formed through the top surface and the front side of the workbench 11 . A through hole is formed in the center of the mold 13 . The discharge groove 12 is located directly below the through hole of the mold 13 .

[0034] The identification plate is placed on the top surface of the mold 13. After being punched by the punching head 16, the waste generated can fall from the central through hole of the mold 13 into the discharge groove 12 and then be discharged.

[0035] Positioning assembly 2, positioning assembly 2 includes two straight-line lasers 26, each straight-line laser 26 is installed under the punching frame 14 through an adjusting assembly and is located on the outside of the piston rod of the hydraulic cylinder 15, the two straight-line lasers 26 are used to emit straight-line lasers, the lasers emitted by the two straight-line lasers 26 are perpendicular to each other, and the adjusting assembly is used to adjust the laser intersection of the two straight-line lasers 26 so that it coincides with the axis of the piston rod of the hydraulic cylinder 15.

[0036] The line laser 26 uses a known line laser generator, and red or green laser can be selected. The line laser generator can emit a line laser. When the laser intersection of the two line lasers 26 coincides with the axis of the piston rod of the hydraulic cylinder 15, this point is the punching point. As long as the position where the sign needs to be punched is aligned with the laser intersection, the positioning can be completed.

[0037] The adjustment assembly includes a guide frame 21 , which is fixedly installed below the top of the punching frame 14 . The axes of the two guide frames 21 are perpendicular to each other, and the intersection of the perpendicular lines of the axes of the two guide frames 21 is located on the axis of the piston rod of the hydraulic cylinder 15 .

[0038] The guide frame 21 is fixedly mounted by bolts below the top of the punching frame 14. The intersection of the vertical line of the axis of the guide frame 21 is located on the axis of the piston rod of the hydraulic cylinder 15, which can facilitate subsequent positioning.

[0039] A slide table 22 is slidably mounted on the guide frame 21 , and a fixing bolt 23 is threadedly connected to a side surface of the slide table 22 . An end surface of the fixing bolt 23 passes through the slide table 22 and abuts against the guide frame 21 .

[0040] Since the fixing bolt 23 is threadedly connected to the slide 22, after tightening the fixing bolt 23, the slide 22 can be fixed by the friction between the fixing bolt 23 and the guide frame 21 to limit the movement of the slide 22. After loosening the fixing bolt 23, the slide 22 can slide freely, which is convenient for adjusting the position.

[0041] A damping rotating member 24 is rotatably mounted in the middle of the bottom surface of the slide 22 , a fixing sleeve 25 is rotatably mounted at the lower end of the damping rotating member 24 , a line laser 26 is clamped and mounted in the middle of the fixing sleeve 25 , and the light emitted by the line laser 26 is directed toward the mold 13 .

[0042] The damping rotating member 24 adopts a well-known bracket with damping, which can be rotated and conveniently positioned. By rotating the damping rotating member 24 and the fixing sleeve 25, the irradiation angle of the line laser 26 can be adjusted.

[0043] The fixing component 3 is located on the top surface of the workbench 11 and on the left and right sides of the mold 13. The fixing component 3 includes a nitrogen spring 31. An electromagnet 34 is installed on the top surface of the nitrogen spring 31 through a lifting frame 32. The electromagnet 34 is used to adsorb the identification plate to fix the identification plate. An ejection component is provided on the lifting frame 32 and on both sides of the electromagnet 34. The ejection component is used to drive the identification plate to separate from the electromagnet 34.

[0044] After the electromagnet 34 is powered on, it can generate magnetic force to absorb the identification plate and fix the identification plate. After the electromagnet 34 is powered off, it loses its magnetism and releases the identification plate.

[0045] After the identification plate is fixed, punching can be performed. The punching head 16 squeezes the identification plate from above. The downward pressure on the identification plate is transmitted to the lifting frame 32 through the electromagnet 34, thereby compressing the nitrogen spring 31 until the bottom surface of the identification plate abuts against the mold 13.

[0046] The punching head 16 continues to descend to complete the punching. At this time, the pressure on the identification plate disappears, and the piston rod of the compressed nitrogen spring 31 moves upward, driving the identification plate to move upward, so that it is separated from the waste material.

[0047] The ejection assembly includes two guide sleeves 33 , which are welded and installed on the left and right sides of the lifting frame 32 and penetrate the lifting frame 32 . A ejection rod 35 is slidably installed in the guide sleeve 33 , and an elastic member 36 is provided between the lower part of the head of the ejection rod 35 and the guide sleeve 33 .

[0048] The elastic member 36 can be a spring. The top surface of the ejector rod 35 should be higher than the electromagnet 34 under normal circumstances.

[0049] The identification plate is placed on the top surface of the ejecting rod 35 . The magnetic force generated by the electromagnet 34 when it is working can drive the identification plate to move downward, thereby driving the ejecting rod 35 to move downward, and further compressing the elastic member 36 .

[0050] After the electromagnet 34 is powered off, the ejector rod 35 moves upward under the elastic force of the elastic member 36 , thereby driving the identification plate to move upward, so that the identification plate is separated from the electromagnet 34 .

[0051] The tail of the ejector rod 35 passes through the guide sleeve 33 and extends downward, and the tail of the ejector rod 35 is threadedly connected with an adjusting nut 37 .

[0052] Since the adjusting nut 37 and the ejecting rod 35 are threadedly connected, rotating the adjusting nut 37 can drive the ejecting rod 35 to move, thereby controlling the height difference between the top surface of the ejecting rod 35 and the top surface of the electromagnet 34 .

[0053] When using the device in this embodiment, the operator first loosens the fixing bolt 23, slides the slide 22, adjusts the left and right positions of the straight-line laser 26, and then rotates the damping rotating member 24 and the fixing sleeve 25 to adjust the irradiation angle of the straight-line laser 26 so that the laser intersection point of the two straight-line lasers 26 coincides with the axis of the piston rod of the hydraulic cylinder 15.

[0054] Place the identification plate on the top surface of the ejector rod 35, and move the identification plate so that the laser intersection is located at the position where punching is required.

[0055] The electromagnet 34 is energized and can generate magnetic force to drive the identification plate to move downward, thereby driving the ejecting rod 35 to move downward, and further compressing the elastic member 36.

[0056] The piston rod of the hydraulic cylinder 15 is controlled to work, driving the punching head 16 to move downward.

[0057] The punching head 16 squeezes the identification plate from above. The downward pressure on the identification plate is transmitted to the lifting frame 32 through the electromagnet 34, thereby compressing the nitrogen spring 31 until the bottom surface of the identification plate abuts against the mold 13.

[0058] The punching head 16 continues to descend to complete the punching. At this time, the pressure on the identification plate disappears, and the piston rod of the compressed nitrogen spring 31 moves upward, driving the identification plate to move upward, so that it is separated from the waste material.

[0059] Then the piston rod of the hydraulic cylinder 15 is controlled to work, driving the punching head 16 to move upward, so that the punching head 16 is separated from the identification plate.

[0060] Then the electromagnet 34 is powered off, and after the electromagnet 34 is powered off, it loses its magnetism, and under the elastic force of the elastic member 36, the ejector rod 35 moves upward, thereby driving the identification plate to move upward, so that the identification plate is separated from the electromagnet 34. At this time, the identification plate can be removed and replaced with a new one.

[0061] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
