[0033] Example

[0034] like Figure 1-4 As shown, a metal sheet cutting device proposed in the present application includes an operating table 1 and a cutting knife 4 arranged at the upper end thereof. A servo motor 3 is installed at the upper end of the operating table 1. The cutting knife 4 is fixedly installed on the output shaft of the servo motor 3. A knife groove 11 is provided at the upper end of the operating table 1. The edge of the cutting knife 4 extends into the knife groove 11. When cutting the sheet, the sheet can be completely cut off without causing damage to the operating table 1. The upper end cover of the operating table 1 is provided with a protective cover 5 located outside the cutting knife 4. When cutting the sheet, sparks can be prevented from splashing and causing harm to workers. A support plate 2 is installed on one side of the upper end of the operating table 1. A support rod for supporting the protective cover 5 is connected to the side of the support plate 2. The support rod is fixedly connected to the protective cover 5. A through hole is provided on the side of the protective cover 5. The output shaft of the servo motor 3 passes through the through hole and can rotate freely.

[0035] Specifically, it also includes a positioning adjustment mechanism 9 installed on the operating table 1, and the positioning adjustment mechanism 9 includes an adjustable bar electromagnet 93 for guiding and positioning the metal plate to be cut. A slide slot 10 is provided on the side of the operating table 1, and the positioning adjustment mechanism 9 includes a U-shaped transmission rod 94 that penetrates and slides in the slide slot 10, and the bar electromagnet 93 is fixedly connected to the upper end of the U-shaped transmission rod 94, and the bar electromagnet 93 is slidably arranged with the upper end of the operating table 1. An inner groove 91 is provided in the operating table 1, and the inner groove 91 is connected with the slide slot 10. An electric telescopic rod 92 is installed in the inner groove 91, and the telescopic end of the electric telescopic rod 92 is fixedly connected with the U-shaped transmission rod 94. By starting the electric telescopic rod 92, the U-shaped transmission rod 94 is driven to slide inside the slide slot 10, and the position of the bar electromagnet 93 is finally adjusted.

[0036] It also includes a push assembly 6 arranged on one side of the operating table 1, and the push assembly 6 includes a push plate 62 arranged vertically with the cutting knife 4. The end of the push plate 62 close to the operating table 1 is provided with a knife avoidance groove 63 located at the same horizontal plane as the cutting knife 4 to prevent the cutting knife 4 from contacting the push plate 62 at the end of the cutting plate, thereby preventing the push plate 62 from being damaged. A groove 7 is provided on one side of the operating table 1, and a cylinder 8 is installed in the groove 7. The push assembly 6 also includes a transmission plate 61 connected to the telescopic end of the cylinder 8, and the transmission plate 61 is fixedly connected to the push plate 62. A conveying section is provided between the protective cover 5 and the operating table 1, and the transmission plate 61 is located at the same horizontal plane as the conveying section, and the push plate 62 can extend into the conveying section to push the cut plate to the other side of the cutting knife 4.

[0037] The specific working principle is: first, adjust the position of the strip electromagnet 93 according to the size of the metal plate to be cut, and the distance between the knife groove 11 and the strip electromagnet 93 is the cutting width; the specific way to adjust the strip electromagnet 93 is to start the electric telescopic rod 92, and adjust the position of the U-shaped transmission rod 94 by the telescopic adjustment of the electric telescopic rod 92. The movement of the U-shaped transmission rod 94 drives the position of the strip electromagnet 93 to change. After adjusting the position of the strip electromagnet 93, place the metal plate to be cut on the upper end of the operating table 1, and make one end of it fit with the strip electromagnet 93. At this time, the strip electromagnet 93 is energized, and the strip electromagnet 93 has an adsorption effect on the metal plate (the plate is made of iron). Next, the cylinder 8 and the servo motor 3 are started. The output shaft of the servo motor 3 rotates to drive the cutting knife 4 to rotate at high speed to cut the plate. The telescopic end of the cylinder 8 retracts to drive the transmission plate 61 to move close to the operating table 1, so that the push plate 62 contacts one end of the plate and pushes the plate to move toward the cutting knife 4 to assist in completing the cutting. It is worth noting that although the bar electromagnet 93 has a positioning adsorption force on the plate (the adsorption force of the bar electromagnet 93 on the plate only plays a guiding and positioning role, and will not fix the plate), under the push of the push plate 62, the plate will slide to one side along the bar electromagnet 93. After the cutting is completed, the bar electromagnet 93 is powered off to abandon the adsorption and positioning of the plate, so as to facilitate the removal of the cut plate. By providing a knife avoidance groove 63 at one end of the push plate 62 close to the cutting knife 4, when the plate is pushed, when the cutting knife 4 cuts the end of the plate, the cutting knife 4 rotates in the knife avoidance groove 63 and will not directly contact the push plate 62, thereby avoiding wear on the push plate 62.

Based on the technical solutions of the present application and the relevant inspirations of the above-mentioned embodiments, those skilled in the art may make various alternative improvements and combinations to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely explanations of the present application, and they are not limitations of the present application.
