[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0043] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] The present invention specifically discloses a sheet metal fast cutting machine, such as Figure 1-Figure 6 As shown, it includes: a bottom plate 1 and a cover shell 2, the left side of the bottom plate 1 is in a rounded shape, the cover shell 2 is fixedly mounted on the bottom plate 1, a handle 3 is fixedly mounted on the cover shell 2, and the handle 3 has a switch 31, and the handle 3 can be held by one hand when in use; according to Figure 2 As shown, two fixed plates 4 are symmetrically fixedly installed at the position of the bottom plate 1 near the round tip shape, and the two fixed plates 4 are rotatably installed with driven gears 5. The driving gear 6 is connected to the two fixed plates 4 and rotates together, and the driving gear 6 is meshed with the driven gear 5; a driving motor 7 is fixedly installed at a position close to the driving gear 6, and the driving motor 7 drives the driving gear 6 to rotate through a gear box. The gear box is a conventional setting, which is mainly used to reduce the output speed of the driving motor 7 to increase the output torque; two inverted tooth cutters 8 are slidably penetrated on the bottom plate 1, and the two inverted tooth cutters 8 are installed on the bottom plate 1 in a side-by-side vertical state, according to Figure 5 As shown, a transverse groove 81 is provided on the top of the inverted tooth cutter 8, and a protrusion 51 is fixedly provided at the eccentric part of the driven gear 5. The protrusion 51 is placed in the transverse groove 81. When the driven gear 5 rotates, the protrusion 51 rotates with it, and the transverse groove 81 is used to push the inverted tooth cutter 8 to move up and down. The lower part of the inverted tooth cutter 8 is provided with an upwardly concave and inclined inverted tooth opening 82. The inverted tooth openings 82 on the two inverted tooth cutters 8 are not in the same height. In this way, when the two inverted tooth cutters 8 move up and down reciprocatingly, the inverted tooth openings 82 move up and down alternately. When the iron sheet is sheared, there will be no situation where the gaps are consistent and the two inverted tooth cutters 8 are stuck at the same time.

[0045] according to Figure 2 and Figure 3As shown, a bottom support plate 9 is movably connected to the bottom of the bottom plate 1. The connection method is that a first adjusting bolt 91 passes through the bottom of the bottom support plate 9 and is screwed to the bottom plate 1. A gap is left between the bottom support plate 9 and the bottom plate 1. A spring is arranged in this gap. When the distance between the bottom support plate 9 and the bottom plate 1 needs to be adjusted to adapt to iron sheets of different thicknesses, it can be completed by rotating the first adjusting bolt 91. The iron sheet to be cut is inserted through the gap. When the inverted tooth cutter 8 moves up and down, the bottom support plate 9 acts as a pad to support the iron sheet, so that the inverted tooth cutter 8 can cut the iron sheet. The cutting is completed; and a feeding port 10 is provided on the bottom support plate 9 to allow the inverted tooth cutting tool 8 to pass through. The iron filings generated by cutting the iron sheet will be discharged downward along the feeding port 10 to avoid being stuck on the bottom support plate 9. A battery compartment 11 is fixedly installed on the bottom plate 1, and the battery compartment 11 is connected to the drive motor 7. A battery pack 12 is movably connected in the battery compartment 11. The battery pack 12 is connected to the battery compartment 11 after opening from the outside of the cover shell 2, so as to provide the drive motor 7 with the power required for work; wherein, in order to prevent sharp burrs from appearing at the fracture after the iron sheet is sheared and cutting the hands, according to Figure 6 As shown, a grinding sheet 18 is fixedly installed on the side wall of the inverted toothed cutter 8, and the side surface of the grinding sheet 18 protrudes from the side surface of the inverted toothed cutter 8. In the process of pushing the device forward to cut the iron sheet, the grinding sheet 18 follows the inverted toothed cutter 8 to move up and down to grind the cut surface of the iron sheet, so as to eliminate sharp burrs; specifically, when it is necessary to cut the iron sheet, the iron sheet can be placed between the bottom plate 1 and the bottom support plate 9, so that the edge of the iron sheet is against the inverted toothed cutter 8, and then the switch 31 on the handle 3 is turned on, and the drive motor 7 is driven to drive the inverted toothed cutter 8 to move up and down. The cutting of the iron sheet can be completed in the process of pushing the device forward. At the same time, according to the shape of the cutting, the cutting direction can also be deflected by the handle 3.

[0046] The present invention uses two inverted toothed cutters 8 to perform up and down reciprocating motion, so that the iron sheet to be cut is placed on the bottom support plate 9 and the cutting is completed. The debris generated during the cutting is discharged through the discharge port 10. During the cutting process, the iron sheet will not get stuck on the inverted toothed cutters 8. The cutting process is safe and risk-free, and it is simple and convenient to use. At the same time, when the equipment moves forward during cutting, the cutting cut can be polished using the provided grinding disc 18 to avoid burrs that cut hands.

[0047] Based on the previous specific implementation, Figure 1 and Figure 2As shown, it also includes: a clamping sleeve 13 that is movably connected to the lower part of the bottom support plate 9, and a protruding hook portion 131 is symmetrically provided on the clamping sleeve 13, and the protruding hook portion 131 is movably clamped in a hook groove 132 opened on the bottom support plate 9, and a storage bin 133 is detachably installed at the bottom of the clamping sleeve 13, and the storage bin 133 is directly opposite to the lower part of the discharge port 10, so in order to facilitate the collection of metal debris generated during the iron sheet shearing process, the metal debris will fall along the discharge port 10 and enter the storage bin 133 to complete the collection; in order to facilitate the removal of the card sleeve 13, a gap is left between the card sleeve 13 and the bottom support plate 9, and a slide-out groove 14 is opened on the bottom support plate 9 above the hook groove 132, and the slide-out groove 14 extends all the way to the corner position of the bottom support plate 9. Therefore, after the card sleeve 13 is inserted into the hook groove 132, continuing to push upwards can make the card sleeve 13 slide out of the hook groove 132 and slide into the slide-out groove 14, and then the card sleeve 13 can be removed by pushing the card sleeve 13 horizontally.

[0048] Based on the previous specific implementation, Figure 2-Figure 4As shown, it also includes: a full gear 15 rotatably mounted on the bottom plate 1, the full gear 15 meshes with the driven gear 5, so that when the driven gear 5 rotates, the full gear 15 rotates along with it; a driven rubber wheel 151 is rotatably arranged at the bottom of the bottom plate 1, and a driving rubber wheel 152 is coaxially mounted on the full gear 15, and the driving rubber wheel 152 rotates along with the full gear 15, and at the same time, the driving rubber wheel 152 is in frictional contact with the driven rubber wheel 151, and the driven rubber wheel 151 rotates due to the rotation of the driving rubber wheel 152, and rotates on the bottom support plate 9. A rubber pulley 153 is provided, and the positions of the rubber pulley 153 and the driven rubber wheel 151 correspond to each other. Therefore, after the iron sheet is placed in the gap between the bottom plate 1 and the bottom support plate 9, it will also be placed between the rubber pulley 153 and the driven rubber wheel 151 and clamped by the rubber pulley 153 and the driven rubber wheel 151. After the iron sheet starts to be sheared, the driven gear 5 drives the full gear 15 to rotate, and then drives the driven rubber wheel 151 to rotate, and pushes the iron sheet to move in the direction of the inverted tooth cutter 8, so that there is no need for manual force to push the equipment to move. At the same time, The advantage of installing a rubber wheel is that when the iron sheet cannot be pushed, it will not cause the full gear 15 and the driven gear 5 to get stuck, and it can only cause wear to the rubber wheel without affecting normal use; wherein, in order to keep the straight state when dealing with straight line cutting, a receiving cavity 16 is opened on the bottom support plate 9 on the side away from the rubber pulley 153, and a first roller set 161 is slidably arranged in the receiving cavity 16, and a second adjusting bolt 162 spirally passes through the bottom support plate 9 and is rotatably connected to the first roller set 161. As the second adjusting bolt 162 is rotated, the first roller set 16 1 can rise or fall, and a second roller group 163 is provided at the bottom of the bottom plate 1 directly above the first roller group 161. The rollers on the first roller group 161 and the second roller group 163 are rubber wheels. When straight line cutting is required, the second adjusting bolt 162 can be rotated to raise the first roller group 161, so that the first roller group 161 and the second roller group 163 press the iron sheet against each other, and at the same time cooperate with the front rubber pulley 153 and the driven rubber wheel 151 to clamp the iron sheet, so that a straight line is formed in the process of the equipment moving forward.

[0049] Based on the previous specific implementation, Figure 1 and Figure 3As shown, it also includes: a driving bevel gear 17 is installed coaxially with the driving gear 6 on the side wall of the fixed plate 4, and a driven bevel gear 171 meshing with the driving bevel gear 17 is rotatably set on the fixed plate 4, and a hexagon socket 172 is fixed on the driven bevel gear 171, and the top of the hexagon socket 172 passes through the top of the cover shell 2. When the battery pack 12 has no power and the equipment needs to be used briefly to complete the cutting, a rocker 173 with an external hexagonal column can be inserted into the top of the hexagon socket 172, and the driving gear 6 can be driven to rotate by rotating the rocker 173, thereby realizing the cutting of the iron sheet; accordingly, if the driving motor 7 fails, it can also be driven directly by using an external driving device using the hexagon socket 172.

[0050] Based on the previous specific implementation, Figure 2 , Figure 7 and Figure 8 As shown, the battery compartment 11 also includes: protruding bars 191 are symmetrically provided on the side walls on both sides of the battery compartment 11, and positioning grooves 192 matching the protruding bars 191 are opened on the side walls on both sides of the battery pack 12. When installing the battery pack 12, the protruding bars 191 and the positioning grooves 192 can be used to cooperate with each other to complete the positioning and insertion. A card slot 193 is opened at the bottom of the battery compartment 11, and a card wedge 195 is hinged at the bottom of the battery pack 12. The end of the card wedge 195 away from the hinge point protrudes and matches the card slot 193. Therefore, after the battery pack 12 is inserted into the battery compartment 11, the card slot 193 The wedge 195 is inserted into the card slot 193, which can effectively prevent the battery pack 12 from sliding out and falling. A protruding power terminal 194 is provided in the battery compartment 11, and a power supply terminal matching the power terminal 194 is provided on the battery pack 12. After they are aligned and contacted with each other, power supply is completed. A shift block 196 is slidably installed on the side wall of the battery pack 12, and the shift block 196 is connected to the card wedge 195. When the battery pack 12 needs to be removed for charging, the shift block 196 can be pushed upward to make the card wedge 195 disengage from the card slot 193, and then the battery pack 12 can be taken out.

[0051] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
