DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0036] As Figures 1 - 3 shown, a counter-rotating sheet metal plate extrusion cutting device includes a fixing frame 5:

[0037] At the horizontal end of the bottom of the fixing frame 5, two cutting tables 8 of equal height are provided, on which the raw materials of two sheet metal plates to be cut can be placed to achieve the effect of reciprocating cutting of the two sheet metal plates;

[0038] On both sides of the horizontal end of the top of the fixing frame 5, driven parts are provided, and transmission frames 6 are movably arranged on both driven parts. At the bottom of the transmission frame 6, cutting parts 7 are provided. At the horizontal end of the top of the fixing frame 5, a driving part connected to the two driven parts is provided, and the two cutting parts 7 are driven to move synchronously in opposite directions. By driving the two driven parts to move through the driving part, the two cutting parts 7 can be driven to rotate in opposite directions, so that the two cutting parts 7 intermittently reciprocate to perform extrusion cutting on the raw materials on the two cutting tables 8, thereby ensuring that the raw materials on the two cutting tables 8 can be extruded and cut one by one;

[0039] The cutting part 7 includes a cutting disc 71 connected to the transmission frame 6. At the bottom of the cutting disc 71, a cutting knife 73 is provided. The cross-section of the cutting knife 73 is in a square structure, and the raw materials on the cutting table 8 can be extruded and cut into sheet metal plates;

[0040] A pressing plate assembly is movably arranged on the inner wall of the cutting disc 71. By the movably arranged pressing plate assembly, when the cutting knife 73 extrudes and cuts the metal plate, the upper surface of the extruded and cut metal plate can be pressed, avoiding the phenomenon that the peripheral edge of the sheet metal plate bulges locally due to the extrusion of the cutting knife 73 during extrusion cutting, thereby ensuring the flatness of the sheet metal plate cutting and improving the extrusion cutting quality.

[0041] The driven part includes a ball screw 4 arranged on the fixing frame 5. A driven bevel gear 3 is arranged on the ball screw 4. The screw grooves on the two ball screws 4 are opened in opposite directions. The driving part includes a motor 1 arranged on the top of the fixing frame 5. At the output end of the motor 1, a driving bevel gear 2 meshing with the two driven bevel gears 3 is provided. By the forward and reverse rotation of the motor 1, the driving bevel gear 2 is driven to rotate. At this time, the driving bevel gear 2 will mesh with the two driven bevel gears 3 and drive the two ball screws 4 to rotate. Since the screw grooves of the two ball screws 4 are in opposite directions, one of the cutting knives 73 on the two ball screws 4 can be driven to press down and cut the sheet metal plate, and the other cutting knife 73 can be driven to move upward and separate from the sheet metal plate, thereby achieving the counter-rotating extrusion cutting effect of the sheet metal plate.

[0042] The bottom of the cutting disc 71 is provided with an installation groove 72, and a positioning pin 74 that is spirally arranged in the installation groove 72 and is clamped with the cutting tool 73. Insert the positioning pin 74 into the installation groove 72 and connect it to the corresponding positioning groove on the cutting tool 73, which can play a role in positioning and strengthening the cutting tool 73, and at the same time achieve the convenient disassembly and assembly effect of the cutting tool 73.

[0043] The pressing plate assembly includes a pressing plate 75 located inside the cutting disc 71. Through holes are provided at both ends of the pressing plate 75 for slide bars 77 to pass through. A regulating rod 76 that extends to the outside of the cutting disc 71 is rotatably arranged on the pressing plate 75. Rotate the regulating rod 76 to drive the pressing plate 75 to move on the slide bars 77, and adjust the distance between the pressing plate 75 and the bottom of the cutting tool 73. When the cutting tool 73 cuts the sheet metal plate, the pressing plate 75 can be made to press against and contact the upper surface of the sheet metal plate, achieving the effect of leveling and pressing the sheet metal plate, and preventing the peripheral edge of the sheet metal plate from bulging locally when being extruded and cut by the cutting tool 73.

[0044] The upper surface of the cutting table 8 is provided with a tool groove 81, which can provide a buffer space for the cutting tool 73 to prevent the cutting tool 73 from colliding with the cutting table 8 after cutting through the sheet metal plate and causing damage.

[0045] It further includes a material ejecting assembly 9. The material ejecting assembly 9 includes a material ejecting plate 91 located in a recessed portion 82 formed on the cutting table 8. A material ejecting rod 92 is provided at the bottom of the material ejecting plate 91, and a spring 93 is arranged between the material ejecting rod 92 and the cutting table 8. When the cutting tool 73 extrudes and cuts the sheet metal plate, the sheet metal plate will press the material ejecting plate 91 into the recessed portion 82. At this time, the material ejecting rod 92 will move downward and stretch the spring 93. When the cutting tool 73 separates from the sheet metal plate, the spring 93 rebounds and resets, causing the material ejecting plate 91 to push the sheet metal plate upward, separating the cut sheet metal plate from the metal raw material, thereby facilitating the unloading operation of the sheet metal plate.

[0046] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
