Technical Field

[0001] The utility model relates to the technical field of sheet metal parts, in particular to a sheet metal part edge waste cutting mechanism. Background Art

[0002] During the manufacturing process of sheet metal parts, a certain amount of scrap is usually generated at the edges. This scrap not only affects the final shape and size of the product, but also increases the difficulty of processing in subsequent steps. Therefore, cutting and recycling this scrap has become a key process step. The scrap that is cut off can be recycled and reused.

[0003] Currently, most common sheet metal edge scrap cutting mechanisms on the market are fixed designs, and the distance between the cutter discs cannot be adjusted according to the actual size of the sheet metal. Although this fixed design can meet some standardized production needs, it often seems inadequate when processing sheet metal parts of different sizes.

[0004] Therefore, a sheet metal edge waste cutting mechanism is needed to solve the above technical defects. Utility Model Content

[0005] The purpose of the present utility model is to provide a sheet metal edge waste cutting mechanism to solve the problem in the above background technology that the distance between the discs cannot be adjusted according to the actual size of the sheet metal.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sheet metal edge waste cutting mechanism, comprising a top plate and a gear, a gear being installed in the middle position inside the top plate, a group of racks being engaged at the front and rear ends of the gear, the racks being movably installed in the top plate, the top ends of the racks being fixedly connected to a group of connecting frames, the bottom ends of the connecting frames being fixedly connected to tool holders, the tool holders being equipped with tool discs, the top end of the top plate being fixedly connected to an adjusting motor, and the output shaft of the adjusting motor being fixedly connected to the gear.

[0008] Preferably, two groups of sliding grooves are opened in the top plate, and the connecting frame is embedded in the sliding grooves and moves.

[0009] Preferably, two groups of racks are provided, and the racks form a centrally symmetrical structure with respect to the gear.

[0010] Preferably, the outer wall of the tool holder is fixedly connected to a cutting motor, the outer wall of the tool holder is movably equipped with a bearing, a cutter disc is assembled in the tool holder, and a fixing screw is fixedly connected between the cutter disc and the bearing.

[0011] Preferably, a lifting motor is fixedly connected to the middle position of the bottom end of the top plate, the output shaft of the lifting motor is fixedly connected to a threaded rod, a threaded block is sleeved on the outside of the threaded rod, and a connecting sleeve is welded to the outside of the threaded block.

[0012] Preferably, the bottom end of the connecting sleeve is fixedly connected to a spring, the bottom end of the spring is fixedly connected to a pressure plate, and the pressure plate and the spring are disassembled and assembled by screws.

[0013] Preferably, limiting rods are welded on both sides of the threaded block, and fixing plates are provided on both sides of the lifting motor. Grooves are provided on the inner side walls of the fixing plates, and the limiting rods are embedded in the grooves and move.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the sheet metal edge waste cutting mechanism not only realizes adaptation to the edge waste of sheet metal parts of different sizes by adjusting the spacing, thereby achieving better cutting effect, but also improves the heat dissipation effect while not affecting the fixation of the cutter disc, thereby extending the service life of the cutter disc, and realizes pressing down and fixing the sheet metal part before cutting to prevent it from shaking, thereby improving the cutting stability;

[0015] By setting up an adjustment motor, a rack and a gear, the two sets of cutter discs can cut the edge waste of sheet metal parts at the same time under the drive of the cutting motor. Due to the different sizes of sheet metal parts, the distance between the cutter discs can be adjusted during cutting. By starting the adjustment motor, the gear is driven to rotate counterclockwise, thereby promoting the relative movement of the two sets of racks, and the horizontal distance between the two sets of cutter discs is relatively shortened. On the contrary, if the gear rotates clockwise, the horizontal distance between the two sets of cutter discs can be relatively widened. By adjusting the distance, the edge waste of sheet metal parts of different sizes can be adapted, and a better cutting effect can be achieved.

[0016] The cutter disc, cutter holder and bearing are provided, and the cutter disc is assembled inside the cutter holder and fixed with the bearing to ensure smooth and high-speed rotation. The detachable design allows the side of the cutter holder to be opened, which does not affect the fixation while improving the heat dissipation effect and extending the service life of the cutter disc.

[0017] By setting up a lifting motor, a threaded rod, a threaded block, a connecting sleeve and a pressure plate, before the cutter disc cuts, the lifting motor drives the threaded rod to rotate, thereby driving the threaded block to move vertically downward, and the connecting sleeve pushes the pressure plate to press the sheet metal, thereby fixing the sheet metal to prevent it from shaking. After the cutting is completed, the pressure plate rises and resets again, thereby improving the stability of the cutting. BRIEF DESCRIPTION OF THE DRAWINGS

The top of the top plate 1 is fixedly connected to an adjusting motor 16, and the output shaft of the adjusting motor 16 is fixedly connected to the gear 19. A guide rail 17 is provided at one end of the rack 20, and a pulley 18 is installed at the end of the rack 20 close to the guide rail 17. The pulleys 18 are respectively embedded in the guide rail 17 and move. Two groups of slide grooves 3 are opened in the top plate 1, and the connecting frame 2 is embedded in the slide groove 3 and moves. Two groups of racks 20 are provided, and the racks 20 form a centrally symmetrical structure with respect to the gear 19;

[0025] Specifically, if Figure 1 and Figure 2 As shown, the two sets of cutter discs 5 can simultaneously cut the edge waste of sheet metal parts under the drive of the cutting motor 6. Due to the different sizes of sheet metal parts, the spacing between the cutter discs 5 can be adjusted during cutting. By starting the adjustment motor 16, the gear 19 is driven to rotate counterclockwise, thereby promoting the relative movement of the two sets of racks 20, and the two sets of cutter discs 5 are relatively shortened in horizontal distance. On the contrary, if the gear 19 rotates clockwise, the two sets of cutter discs 5 can be relatively widened in horizontal distance, and the edge waste of sheet metal parts of different sizes can be adapted by adjusting the spacing.

[0026] Example 2: The outer wall of the tool holder 4 is fixedly connected to the cutting motor 6, the outer wall of the tool holder 4 is movably equipped with a bearing 22, the tool holder 4 is equipped with a cutter disc 5, and a fixing screw 21 is fixedly connected between the cutter disc 5 and the bearing 22;

[0027] Specifically, if Figure 1 and Figure 4 As shown, the cutter disc 5 is assembled inside the cutter holder 4 and is fixed with the bearing 22 to ensure smooth and high-speed rotation. Through the detachable design, the side of the cutter holder 4 can be opened, which does not affect the fixation while improving the heat dissipation effect and extending the service life of the cutter disc 5.

[0028] Embodiment 3: A lifting motor 15 is fixedly connected to the middle position of the bottom end of the top plate 1, and the output shaft of the lifting motor 15 is fixedly connected to a threaded rod 14. A threaded block 13 is sleeved on the outside of the threaded rod 14, and a connecting sleeve 12 is welded to the outside of the threaded block 13. The bottom end of the connecting sleeve 12 is fixedly connected to a spring 11, and the bottom end of the spring 11 is fixedly connected to a pressure plate 10. The pressure plate 10 and the spring 11 are disassembled and assembled by screws. Limit rods 8 are respectively welded on both sides of the threaded block 13. Fixed plates 7 are respectively provided on both sides of the lifting motor 15. The inner side walls of the fixed plate 7 are opened with grooves 9, and the limit rods 8 are respectively embedded in the grooves 9 and move;

[0029] Specifically, if Figure 1 and Figure 2 As shown, before the cutter disc 5 starts cutting, the lifting motor 15 drives the threaded rod 14 to rotate, thereby driving the threaded block 13 to move vertically downward, and the connecting sleeve 12 pushes the pressure plate 10 to press the sheet metal, thereby fixing the sheet metal to prevent it from shaking. After the cutting is completed, the pressure plate 10 rises and resets again.

[0030] Working principle: Before the cutter disc 5 starts cutting, the lifting motor 15 drives the threaded rod 14 to rotate, thereby driving the threaded block 13 to move vertically downward, and the connecting sleeve 12 pushes the pressure plate 10 to press the sheet metal, thereby fixing the sheet metal to prevent it from shaking. The two sets of cutter discs 5 are driven by the cutting motor 6 to cut the edge waste of the sheet metal at the same time. Due to the different sizes of sheet metal, the spacing between the cutter discs 5 can be adjusted during cutting. By starting the adjustment motor 16, the gear 19 is driven to rotate counterclockwise, thereby promoting the relative movement of the two sets of racks 20, and the two sets of cutter discs 5 are relatively shortened in horizontal distance. On the contrary, if the gear 19 rotates clockwise, the two sets of cutter discs 5 can be relatively widened in horizontal distance, and the spacing can be adjusted to adapt to the edge waste of sheet metal parts of different sizes. After cutting is completed, the pressure plate 10 rises and resets again.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention; any reference signs in the claims should not be construed as limiting the claims to which they relate.
