Description

Technical Field

[0001] This application relates to the technical field of sheet metal processing equipment, and in particular to a sheet metal cutting device. Background Technology

[0002] When preparing three-piece cans, the iron sheet roll is usually cut into blocks, and the surface of the blocks is printed. The printed blocks then enter the cutting process. In this process, the blocks are first cut longitudinally to form strips, and then the strips are cut transversely to cut the blocks into the required size for a single three-piece can body, thus completing the iron sheet cutting.

[0003] Because the cutting direction of the blade is perpendicular to that of the blade during transverse cutting, when transversely cutting strips of iron, it is necessary to manually move the strips to the transverse cutting point, which affects work efficiency. Utility Model Content

[0004] In order to reduce the adverse impact on work efficiency, this application provides a sheet metal cutting device.

[0005] The sheet metal cutting device provided in this application adopts the following technical solution: A sheet metal cutting device includes a frame and a slitting assembly mounted on the frame. One end of the frame is provided with a first conveyor belt that feeds sheet metal to the slitting assembly. The end of the frame away from the first conveyor belt is provided with a second conveyor belt perpendicular to it. The end of the second conveyor belt near the slitting assembly is provided with a steering assembly for driving the sheet metal to rotate. The height of the second conveyor belt is lower than that of the first conveyor belt. The steering assembly includes multiple steering rods rotatably connected to the frame and arranged sequentially along the length of the second conveyor belt. The steering rods are located on the upper side of the second conveyor belt. Each adjacent steering rod has a locking groove on its closest side, allowing sheet metal to be inserted between adjacent steering rods. Both sides of the sheet metal overlap the steering rods through the locking grooves. The frame is provided with a rotating component that drives the sheet metal to detach from the steering rods and fall onto the second conveyor belt.

[0006] By adopting the above technical solution, the first conveyor belt transports the iron sheet to the slitting assembly. After slitting, the iron sheet is turned by the turning assembly and moved to the second conveyor belt, which then transports it to the cross-cutting station. This reduces the possibility of manually driving the iron sheet to the cross-cutting station and minimizes the adverse impact on work efficiency.

[0007] The slitting iron sheet is cut into multiple strips along the width of the second conveyor belt and moved to the turning rod. At this time, both sides of the iron sheet are connected to the adjacent turning rod through the snap-fit ​​groove. The turning rod is driven by the rotating component to rotate simultaneously in the same clockwise direction, so that one side of the iron sheet is lifted and the other side moves to the lower side of the corresponding turning rod, so that the iron sheet falls onto the second conveyor belt under its own weight, which facilitates the turning of the iron sheet and improves work efficiency.

[0008] Optionally, one end of the steering rod away from the slitting assembly passes through the frame and is rotatably connected to the frame. The rotating component includes a belt that corresponds one-to-one with two adjacent steering rods and is mounted on the two adjacent steering rods. A first motor is mounted on the end of one of the steering rods.

[0009] By adopting the above technical solution, the first motor drives the belt to rotate the steering rod in the same clockwise direction, which facilitates the iron sheet to be driven off the steering rod and fall onto the second conveyor belt. When the iron sheet falls onto the second conveyor belt, the first motor drives the steering rod to reset through the belt, which facilitates the steering of the next batch of iron sheets and improves work efficiency.

[0010] Optionally, when the steering rod receives the iron sheet through the snap-fit ​​groove, a partition plate is fixedly connected to the upper side of the steering rod along the length direction of the steering rod.

[0011] By adopting the above technical solution, when the iron sheet moves between adjacent steering rods, the partition plate drives the adjacent iron sheets to separate, reducing the possibility that the iron sheets will overlap and have difficulty entering the adjacent steering rods, thus reducing the adverse impact on work efficiency.

[0012] Optionally, a limiting ring is sleeved and fixedly connected to one end of the steering rod near the belt, and limiting plates are fixedly connected to both sides of the second conveyor belt along its length. The limiting plate near the limiting ring and the limiting ring are located in the same vertical plane parallel to the length direction of the second conveyor belt.

[0013] By adopting the above technical solution, the iron sheet moves between the two adjacent steering rods. When the end of the iron sheet moves to contact the limiting ring, the limiting ring restricts the movement of the iron sheet. At this time, the iron sheet is separated from the longitudinal shear assembly and is completely located in the adjacent steering rod, which facilitates the steering rod to drive the iron sheet to turn and reduces the adverse effects on work efficiency.

[0014] Optionally, the slitting assembly includes a rotating shaft located on the upper side of the first conveyor belt and rotatably connected to the frame. Multiple evenly distributed annular cutters are threaded through and fixedly connected to the rotating shaft. A driven shaft is threaded through and fixedly connected to the lower side of the frame. Mounting wheels, each corresponding to one of the cutters, are threaded through and fixedly connected to the driven shaft. Each mounting wheel has a receiving groove on its upper side, and each cutter is inserted into a corresponding receiving groove on its lower side. Multiple drive wheels are threaded through and fixedly connected to the rotating shaft. Multiple driven wheels, each corresponding to one of the drive wheels, are rotatably connected to the driven shaft. The frame is provided with a driving component for driving the rotating shaft to rotate.

[0015] By adopting the above technical solution, the driving component drives the rotating shaft to rotate, and the iron sheet moves to the end and is inserted between the rotating shaft and the driven shaft. At this time, the driving wheel and the driven wheel are located on both sides of the iron sheet in the vertical direction and drive the iron sheet to move towards the steering rod. The cutter rotates with the rotating shaft and cuts the iron sheet, thereby cooperating with the receiving groove on the mounting wheel and cutting the iron sheet into strips as the iron sheet moves, thus improving work efficiency.

[0016] Optionally, each of the mounting wheels is provided with an oil delivery pipe whose lower end is inserted into the receiving groove and delivers lubricating oil to the receiving groove, and the lower end of each oil delivery pipe is provided with a sealing element.

[0017] By adopting the above technical solution, when the cutter cuts the iron sheet, the lower side of the cutter is inserted into the receiving groove and comes into contact with the lubricating oil. At this time, the sealing component blocks the oil supply pipe, thereby lubricating the cutter, reducing the friction between the cutter and the iron sheet and the generation of heat, which may accelerate the wear of the cutter. When the lubricating oil in the receiving groove decreases, the sealing component opens the oil supply pipe, which facilitates the oil supply pipe to deliver lubricating oil to the receiving groove, further improving work efficiency.

[0018] Optionally, the sealing component includes a sealing ball located at the lower end of the oil delivery pipe and capable of sealing the oil delivery pipe. The upper side of the sealing ball is fixedly connected to an installation rod that is inserted into the oil delivery pipe and slidably connected to the oil delivery pipe, and the sealing ball is capable of floating at the surface of the lubricating oil.

[0019] By adopting the above technical solution, when there is a lot of lubricating oil in the receiving tank, the sealing ball floats on the surface of the lubricating oil and blocks the oil delivery pipe. When the lubricating oil in the receiving tank decreases, the sealing ball drives the mounting rod to move downward with the lubricating oil surface and open the oil delivery pipe, which facilitates the replenishment of lubricating oil into the receiving tank. At this time, the lubricating oil level rises and drives the sealing ball and mounting rod to move upward until the oil delivery pipe is blocked, thus facilitating the timely replenishment of lubricating oil into the receiving tank and improving work efficiency.

[0020] In summary, this application includes at least one of the following beneficial technical effects: The slitting iron sheet is cut into multiple strips along the width of the second conveyor belt and moved to the turning rod. At this time, both sides of the iron sheet are connected to the adjacent turning rod through the snap-fit ​​groove. The turning rod is driven by the rotating component to rotate in the same clockwise direction, so that one side of the iron sheet is lifted and the other side moves to the lower side of the corresponding turning rod, so that the iron sheet falls onto the second conveyor belt under its own weight, which facilitates the turning of the iron sheet. When the iron sheet moves between adjacent steering rods, the partition plate drives the adjacent iron sheets to separate, reducing the possibility that the iron sheets will overlap and have difficulty entering the adjacent steering rods, thus reducing the adverse impact on work efficiency. When the cutter cuts the sheet metal, the lower side of the cutter is inserted into the receiving groove and comes into contact with the lubricating oil. At this time, the sealing component blocks the oil supply pipe, thereby lubricating the cutter, reducing the friction between the cutter and the sheet metal and the generation of heat, which may accelerate the wear of the cutter. When the lubricating oil in the receiving groove decreases, the sealing component opens the oil supply pipe, which facilitates the delivery of lubricating oil to the receiving groove.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses a sheet metal cutting device.

[0029] Example 1 Reference Figure 1 A sheet metal cutting device includes a frame 1 and a slitting assembly 2 mounted on the upper side of the frame 1. A first conveyor belt 11 is installed at one end of the frame 1, which is horizontal and conveys iron sheets to the slitting assembly 2. Two rotating rollers 12 are rotatably connected to the side of the slitting assembly 2 away from the first conveyor belt 11. The rollers 12 are arranged sequentially along the length direction of the first conveyor belt 11 and parallel to the width direction of the first conveyor belt 11. The same end of each rotating roller 12 passes through the frame 1 and is fixedly connected to a second motor 121.

[0030] A horizontal second conveyor belt 13 is provided on the side of the rotating roller 12 away from the slitting assembly 2 and mounted on the frame 1 and arranged along the width direction of the first conveyor belt 11. The height of the second conveyor belt 13 is lower than that of the first conveyor belt 11. The second conveyor belt 13 transmits the strip-shaped iron sheet cut by the slitting assembly 2 to the cross-cutting station in a direction parallel to the width of the first conveyor belt 11. A steering assembly 3 for driving the iron sheet to turn is provided on the upper side of the second conveyor belt 13 near the end of the slitting assembly 2.

[0031] The first conveyor belt 11 transports the iron sheet to the slitting assembly 2. At this time, the second motor 121 drives the rotating roller 12 to rotate and moves the slitting iron sheet to the turning assembly 3. After the turning assembly 3 turns the iron sheet, it moves the iron sheet to the second conveyor belt 13 and is then transported to the cross-cutting station via the second conveyor belt 13, reducing the possibility of manually driving the iron sheet to the cross-cutting station.

[0032] Reference Figure 1 and Figure 2 The slitting assembly 2 includes a horizontal rotating shaft 21 located on the upper side of the first conveyor belt 11 near the rotating roller 12. A drive unit is provided on the frame 1 to drive the rotating shaft 21 to rotate. In this embodiment, the drive unit is a third motor 211 fixedly connected to the outside of the frame 1 and mounted on the end of the rotating shaft 21. The ends of the rotating shaft 21 are all inserted into and rotatably connected to the frame 1, and the rotating shaft 21 is arranged along the width direction of the first conveyor belt 11. Multiple vertically oriented annular cutters 22, evenly distributed along the length direction of the rotating shaft 21, are threaded through and fixedly connected to the rotating shaft 21. In this embodiment, three cutters are used.

[0033] Multiple drive wheels 23 are threaded through and fixedly connected to the rotating shaft 21, and each cutter 22 is located between two adjacent drive wheels 23. A horizontal driven shaft 24 is provided on the lower side of the rotating shaft 21, parallel to the rotating shaft 21 and fixedly connected to the frame 1 at its end. Three mounting wheels 25, each corresponding to a cutter 22, are fixedly connected to the driven shaft 24. Each mounting wheel 25 has a receiving groove 251 on its upper side, and the lower side of the cutter 22 is inserted into the corresponding receiving groove 251. Multiple driven wheels 26, each corresponding to a drive wheel 23, are threaded through and rotatably connected to the driven shaft 24.

[0034] The third motor 211 drives the rotating shaft 21 to rotate. The iron sheet moves along the first conveyor belt 11 to the end and is inserted between the rotating shaft 21 and the driven shaft 24. At this time, the driving wheel 23 and the driven wheel 26 are located on both sides of the iron sheet in the vertical direction. The driven wheel 26 rotates under the action of friction, so that it cooperates with the driving wheel 23 and drives the iron sheet to move closer to the steering rod 31. At the same time, the cutter 22 rotates with the rotating shaft 21 and cuts the iron sheet, so that it cooperates with the receiving groove 251 on the mounting wheel 25 and moves with the iron sheet to cut the iron sheet into strips.

[0035] Reference Figure 1 and Figure 3 The steering assembly 3 includes multiple horizontal steering rods 31 arranged parallel to the width direction of the second conveyor belt 13 and sequentially along the length direction of the second conveyor belt 13. In this embodiment, five rods are provided, all of which are rotatably connected to the frame 1. The frame 1 is provided with a rotating component 32 that drives the steering rods 31 to rotate simultaneously in the same clockwise direction. Adjacent steering rods 31 have engaging grooves 311 along their length direction on their sides. Iron sheets are driven by the rotating roller 12 and moved between adjacent steering rods 31. At this time, the iron sheets are sequentially arranged along the length direction of the second conveyor belt 13, and both sides of the iron sheets overlap with the corresponding two steering rods 31 through the engaging grooves 311.

[0036] When the iron sheet overlaps the corresponding steering rod 31, a vertical partition plate 312 is fixedly connected to the upper side of each steering rod 31 and is arranged along the length direction of the steering rod 31, and the iron sheet is located between two adjacent partition plates 312. The end of the steering rod 31 away from the first conveyor belt 11 is sleeved and fixedly connected to a vertical limiting ring 313 located in the frame 1. Both sides of the upper side of the second conveyor belt 13 are fixedly connected to vertical limiting plates (not shown in the figure) arranged along the length direction of the second conveyor belt 13. The limiting plate closer to the first conveyor belt 11 is fixedly connected to the frame 1, and the limiting plate away from the first conveyor belt 11 and the limiting ring 313 are both located in the same vertical plane parallel to the length direction of the second conveyor belt 13.

[0037] The ends of the steering rods 31 away from the first conveyor belt 11 all pass through the frame 1. The rotating component 32 includes a first motor 321 installed at the end of one of the steering rods 31 and fixedly connected to the frame 1, and belts 322 are installed at the ends of the two adjacent steering rods 31.

[0038] After the longitudinally cut iron sheet is cut into multiple strip-shaped iron sheets arranged along the width direction of the second conveyor belt 13, it is moved to the turning rod 31 by the rotating roller 12. When the end of the iron sheet moves to contact the limiting ring 313, the limiting ring 313 restricts the movement of the iron sheet. At this time, the iron sheet is separated from the rotating roller 12 and is completely located in the adjacent turning rod 31. At this time, both sides of the iron sheet are overlapped on the adjacent turning rod 31 through the snap-fit ​​groove 311. The partition plate 312 drives the adjacent iron sheets to separate, reducing the possibility that the iron sheets overlap each other and are difficult to enter the adjacent turning rod 31.

[0039] The first motor 321 drives the belt 322 to drive the steering rod 31 to rotate clockwise at the same time, so that one side of the iron sheet is lifted and the other side moves to the lower side of the corresponding steering rod 31. The iron sheet falls onto the second conveyor belt 13 under its own weight and moves along the second conveyor belt 13. At this time, the limiting plate limits the iron sheet, and the first motor 321 drives the steering rod 31 to reset through the belt 322, so as to facilitate the steering of the next batch of iron sheets.

[0040] The implementation principle of Example 1 is as follows: The slit iron sheet is moved to the steering rod 31 until the end contacts the limiting ring 313. At this time, both sides of the iron sheet are connected to the adjacent steering rod 31 through the snap-fit ​​groove 311. The steering rod 31 is driven to rotate in the same clockwise direction at the same time, so that one side of the iron sheet is lifted and the other side moves to the lower side of the corresponding steering rod 31. The iron sheet falls onto the second conveyor belt 13 under its own weight and moves along the second conveyor belt 13. The first motor 321 drives the steering rod 31 to reset through the belt 322, thus completing the turning of the iron sheet.

[0041] Example 2 Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the receiving groove 251 is filled with lubricating oil, and the upper side of the mounting wheel 25 is fixedly connected with a vertical oil delivery pipe 4 whose lower end is inserted into the receiving groove 251. The oil delivery pipe 4 is filled with lubricating oil, and the upper end of the oil delivery pipe 4 has an opening 41 for lubricating oil to be introduced into the oil delivery pipe 4. The lower end of the oil delivery pipe 4 is provided with a sealing member 5 to block the oil delivery pipe 4.

[0042] Reference Figure 5The sealing component 5 includes a sealing ball 51 that can float on the surface of the lubricating oil. The sealing ball 51 is located at the lower end of the oil delivery pipe 4, and a vertical connecting rod 52 is fixedly connected to the upper side of the sealing ball 51. The connecting rod 52 is inserted into the oil delivery pipe 4, and a horizontal mounting rod 53 that is slidably connected to the side wall of the oil delivery pipe 4 is fixedly connected to the upper end of the connecting rod 52.

[0043] When the sealing ball 51 blocks the oil supply pipe 4, the connecting rod 52 and the mounting rod 53 are both located in the oil supply pipe 4, and the lubricating oil level in the receiving groove 251 is located at the lower end of the oil supply pipe 4.

[0044] The implementation principle of Example 2 is as follows: When the cutter 22 cuts the iron sheet, the lower side of the cutter 22 is inserted into the receiving groove 251 and comes into contact with the lubricating oil. At this time, the sealing ball 51 blocks the oil supply pipe 4, thereby lubricating the cutter 22 and reducing the possibility of accelerated wear of the cutter 22 due to the heat generated by the friction between the cutter 22 and the iron sheet. When the lubricating oil in the receiving groove 251 decreases, the sealing ball 51 drives the connecting rod 52 and the mounting rod 53 to move downward with the lubricating oil level and open the oil supply pipe 4, thereby replenishing the lubricating oil in the receiving groove 251. At this time, the lubricating oil level rises and drives the sealing ball 51, the connecting rod 52 and the mounting rod 53 to move upward until the oil supply pipe 4 is blocked.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
