[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1 like Figures 1 to 5 As shown, the present invention provides a metal sheet processing and cutting machine, including a cutting frame 1; a material tray assembly 2 movably disposed on the cutting frame 1; and a cutting mechanism 3 movably disposed above the material tray assembly 2. The material tray assembly 2 includes a disc body 21 movably disposed on the cutting frame 1, a support rod groove 22 is provided in the disc body 21, the support rod groove 22 is a through groove structure, and multiple support rods 23 are horizontally slidably disposed in the support rod groove 22. Two pressure plates 24 are symmetrically disposed on the top surface of the disc body 21, and a notch rod 25 is provided on the top surface of the disc body 21 away from the pressure plate 24. The cutting mechanism 3 includes an adjusting frame 31 slidably disposed on the cutting frame 1, and a circular cutting saw 32 is connected to the adjusting frame 31 through a lead screw and nut assembly 4. The position of the circular cutting saw 32 corresponds to the position of the disc body 21.

[0028] Before cutting, the metal sheet is placed on the top surface of the disc 21, and then the metal sheet is pressed and positioned using the pressure plate 24 as needed. The disc 21 is moved on the cutting frame 1 (the disc 21 can be pushed manually or a cylinder connected to the disc 21 can be installed on the cutting frame 1 to move the disc 21 under the push of the cylinder). When the metal sheet on the disc 21 moves to a position that matches the disc cutting saw 32, the disc cutting saw 32 can cut the metal sheet (the position of the disc cutting saw 32 can also be adjusted on the adjusting frame 31 by the lead screw and nut assembly 4 according to the cutting position). The cutting position of the disc cutting saw 32 corresponds to the position of the support rod groove 22 inside the disc 21, thus ensuring the normal cutting of the metal sheet without interference with the disc cutting saw 32. The notch rod 25 can be used to position the metal sheet, improving the accuracy of the metal sheet cutting position.

[0029] Example 2 Based on Example 1, such as Figures 1 to 2 , Figures 4 to 5 As shown, a groove 11 is provided on the top surface of the cutting frame 1, and the disc body 21 is slidably disposed in the groove 11. Slide grooves 12 are provided on the opposite side walls of the groove 11. Multiple slide rods 13 are provided on the outer peripheral wall of the disc body 21, each corresponding to a slide groove 12. The slide rods 13 are slidably disposed in the corresponding slide grooves 12. The length directions of the groove 11, the slide grooves 12, and the support rods 23 are all the same.

[0030] After the metal sheet is placed on the top surface of the disc 21, the position of the disc 21 is adjusted by sliding it in the groove 11 according to the different cutting positions. At this time, the slide bar 13 on the outer peripheral wall of the disc 21 can slide in the corresponding slots 12 on the two side walls of the groove 11, which helps to keep the position of the disc 21 stable when sliding, thereby improving the quality of metal sheet cutting.

[0031] The support rod groove 22 has rod sliding grooves 221 on its two opposing side walls. The two ends of the support rod 23 are slidably disposed in the two rod sliding grooves 221 along its length. The top surface of the support rod 23 is on the same horizontal plane as the top surface of the disc body 21. This allows the position of the support rod 23 to be slidably adjusted in the support rod groove 22 according to the different cutting positions of the metal sheet, so as to provide support during the cutting of the metal sheet and help prevent or reduce the deformation of the metal sheet during cutting. At the same time, the circular cutting saw 32 will not interfere with the support rod 23 when cutting the metal sheet.

[0032] Example 3 Based on Example 1, such as Figures 1 to 4 , Figures 7 to 8 As shown, the pressure plate 24 includes a main pressure plate 241, which is rotatably mounted on the top surface of the disc body 21 via a first rotating shaft 242; a secondary pressure plate 243 is rotatably mounted on the end of the main pressure plate 241 away from the disc body 21 via a second rotating shaft 244, and the top surface of the secondary pressure plate 243 is matched with the bottom surface of the main pressure plate 241. The bottom surface of the main pressure plate 241 and the top surface of the disc body 21 are spaced apart, and the bottom surface of the secondary pressure plate 243 is matched with the top surface of the disc body 21; multiple pressure rods 245 are provided, and the multiple pressure rods 245 are movably mounted on the main pressure plate 241; each pressure rod 245 includes a pressure rod hole 2451, which is provided on the main pressure plate 241 and is close to the top surface of the main pressure plate 241. The pressure rod hole 2451 has an internal threaded hole structure, and the bottom end of the pressure rod hole 2451 near the main pressure plate 241 is a smooth hole structure. The external threaded rod 2452 is threadedly connected to the pressure rod hole 2451. The ball 2453 is rotatably embedded in the bottom end of the external threaded rod 2452 near the main pressure plate 241, and the ball 2453 is located outside the pressure rod hole 2451. The diameter of the ball 2453 is smaller than the inner diameter of the pressure rod hole 2451, and the diameter of the ball 2453 is smaller than the height of the pressure rod hole 2451. The arc-shaped guide groove 2454 is provided on the auxiliary pressure plate 243. There are multiple arc-shaped guide grooves 2454, and each arc-shaped guide groove 2454 corresponds to a pressure rod 245. The ball 2453 is movably disposed in the corresponding arc-shaped guide groove 2454.

[0033] After the metal sheet is placed on the plate 21, the positions of the main pressure plate 241 and the secondary pressure plate 243 can be adjusted according to the different thicknesses of the metal sheet, thereby clamping and limiting the metal sheet. That is, when the thickness of the metal sheet is large, the position of the main pressure plate 241 can be adjusted by rotating the first shaft 242 as the axis, so that the outer peripheral wall of the main pressure plate 241 abuts against the outer peripheral wall of the metal sheet (at this time, the metal sheet is clamped by the outer peripheral walls of the two main pressure plates 241). When the thickness of the metal sheet is small, the position of the main pressure plate 241 can be adjusted by rotating the first shaft 242 as the axis, and then the position of the secondary pressure plate 243 can be adjusted by rotating the second shaft 244 as the axis, so that the secondary pressure plate 243 presses against the top surface of the metal sheet, thereby fixing the position of the metal sheet.

[0034] Alternatively, when the thickness of the metal plate is compatible with the distance between the bottom surface of the main pressure plate 241 and the top surface of the disc 21, the position of the main pressure plate 241 can be adjusted by rotating the main pressure plate 241 around the pivot 242, and then the external threaded rod 2452 can be adjusted by rotating it in the pressure rod hole 2451, so that the ball 2453 is pressed against the top surface of the metal plate, thereby fixing the position of the metal plate.

[0035] Both rotating shaft 242 and rotating shaft 244 are externally threaded rod-shaped structures, and both rotating shaft 242 and rotating shaft 244 are threaded with locking nuts. This allows the locking nuts to be tightened after adjusting the position of the main pressure plate 241 by rotating shaft 242 or the position of the secondary pressure plate 243 by rotating shaft 244, thus fixing the position of the main pressure plate 241 or the secondary pressure plate 243 and facilitating the positioning of the metal sheet.

[0036] The bottom surfaces of the main pressure plate 241 and the secondary pressure plate 243 can be embedded with anti-slip rubber layers to increase friction when pressing the metal sheet and improve the firmness of fixing the metal sheet.

[0037] When the thickness of the metal sheet is matched with the distance between the top surface of the main pressure plate 241 and the top surface of the disc 21, the position of the two main pressure plates 241 can be adjusted by rotating the pivot 242, thereby adjusting the position of the two main pressure plates 241 after clamping the metal sheet, and realizing cutting at different positions on the metal sheet.

[0038] Example 4 Based on Example 1, such as Figures 3 to 4 , Figure 6As shown, the notch rod 25 includes a left fixed rod 251; the left fixed rod 251 and the right fixed rod 252 are slidably spaced on the top surface of the disc body 21 away from the end of the pressure plate 24; there are two adjusting rods 253, one of which is slidably disposed inside the left fixed rod 251 and the right fixed rod 252; there are two locking bolts 254, and one locking bolt 254 is movably disposed through the top surface of the left fixed rod 251 and the right fixed rod 252, respectively, and the locking bolt 254 movably passes through the top surface of the left fixed rod 251 or the top surface of the right fixed rod 252 and abuts against the adjusting rod 253; the bottom surfaces of the left fixed rod 251 and the right fixed rod 252 are slidably disposed on the top surface of the disc body 21, and the adjusting rods 253 are parallel and spaced apart from the top surface of the disc body 21.

[0039] By sliding and adjusting the distance between the left fixing rod 251 and the right fixing rod 252 on the top surface of the disc 21, the metal sheet can be positioned during cutting, ensuring it is located between the left and right fixing rods 251 and 252, thus improving the accuracy of the cutting position. Depending on the thickness of the metal sheet placed on the disc 21, the position of the adjusting rod 253 can be adjusted within the left and right fixing rods 251 and 252. The adjusting rod 253 is used to press and position the metal sheet. Specifically, when the metal sheet is thin and its thickness matches the distance between the adjusting rod 253 and the top surface of the disc 21, the adjusting rod 253 can be slid within the left and right fixing rods 251 and 252 after the metal sheet is placed on the disc 21, ensuring the bottom surface of the adjusting rod 253 is positioned within the metal sheet. Above the top surface of the sheet metal, tighten the locking bolt 254 so that the locking bolt 254 passes through the top surface of the left fixing rod 251 or the top surface of the right fixing rod 252 and abuts against the adjusting rod 253. This fixes the adjusting rod 253 within the left fixing rod 251 or the right fixing rod 252, preventing warping during sheet metal cutting and thus helping to maintain the stability of the sheet metal's position during cutting. When the sheet metal is thick, the adjusting rod 253 can slide within the left fixing rod 251 and the right fixing rod 252, causing the adjusting rod 253 to be offset from the top surface of the disc 21. At this time, the sheet metal placed on the top surface of the disc 21 can be positioned between the left fixing rod 251 and the right fixing rod 252 (i.e., the opposite side walls of the sheet metal are in contact with the side walls of the left fixing rod 251 and the right fixing rod 252, respectively).

[0040] Example 5 Based on Example 1, such as Figure 1As shown, the cutting frame 1 has an adjustment groove 311, and the adjustment frame 31 is slidably disposed in the adjustment groove 311. The length direction of the adjustment groove 311 is perpendicular to the length direction of the slide groove 12. The lead screw and nut assembly 4 is disposed on the adjustment frame 31. The disc cutting saw 32 is connected to the lead screw and nut in the lead screw and nut assembly 4, and the disc cutting saw 32 is located below the bottom surface of the adjustment groove 311. The lead screw and nut assembly 4 is provided with multiple adjusting cylinders. The disc cutting saw 32 is rotatably connected to the piston rod of the adjusting cylinder, and the end of the disc cutting saw 32 away from the piston rod of the adjusting cylinder is rotatably hinged to the lead screw and nut in the lead screw and nut assembly 4.

[0041] According to different cutting needs on the metal sheet, the position of the adjusting frame 31 can be slidably adjusted in the adjusting groove 311 (a cylinder can be installed in the adjusting groove 311, and the adjusting frame 31 can be slidably adjusted by the cylinder). The position of the circular cutting saw 32 can be adjusted by the lead screw and nut assembly 4 (the lead screw and nut assembly 4 is existing technology, so it will not be described in detail here). This allows the circular cutting saw 32 to cut at different positions on the metal sheet as needed. At the same time, it is also convenient to rotate and adjust the position of the circular cutting saw 32 by adjusting the cylinder, so as to meet the needs of various cutting positions.

[0042] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
