[0011] Beneficial effects

[0012] This utility model provides a metal sheet cutting device. It has the following advantages: This metal sheet cutting device, through the cooperation of a slider, a first horizontal plate, a storage box, a first column, a first rotating roller, a first cover, a first hydraulic cylinder, a second rotating roller, a second column, and a second motor, achieves automatic feeding of the metal sheet when cutting is required.

Frequent manual handling of the sheet is labor-intensive and inefficient, increasing labor costs and reducing the working efficiency of the metal sheet cutting equipment.

[0013] By coordinating photoelectric sensors, relays, support plates, oil tanks, oil pumps, connecting pipes, and nozzles, the relays activate the oil pump when the metal sheet cutting equipment is feeding the sheet. The oil pump then drives the nozzles to spray stretching oil onto the surface of the metal sheet, reducing friction. This solves the problem in existing metal sheet cutting equipment where metal sheets are squeezed and collided with each other during feeding, causing friction between the surface of the metal sheet and adjacent metal sheets, resulting in scratches and reducing the smoothness and production quality of the metal sheets.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Existing sheet metal cutting equipment requires manual handling of the sheet metal, including lifting, moving, and fixing the sheet metal. Frequent manual handling of sheet metal is labor-intensive and inefficient, which increases labor costs and reduces the working efficiency of sheet metal cutting equipment.

[0023] In view of this, the present invention provides a metal sheet cutting device. This metal sheet cutting device, through the cooperation of a slider, a first horizontal plate, a storage box, a first column, a first rotating roller, a first cover, a first hydraulic cylinder, a second rotating roller, a second column, and a second motor, achieves the effect of automatically feeding the metal sheet when it needs to be cut. The operator places the metal sheet in the storage box, the first horizontal plate pushes the metal sheet in the storage box, and the second motor drives the second rotating roller to automatically feed the metal sheet. This solves the problem that existing metal sheet cutting equipment requires manual handling of metal sheets to the cutting equipment, including lifting, moving, and fixing the sheet. The frequent manual handling of sheet sheets is labor-intensive and inefficient, thus increasing labor costs and reducing the working efficiency of the metal sheet cutting equipment.

[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.

[0025] Example 1, by Figure 1-6As can be seen, the metal sheet cutting equipment in this case includes a housing 1, inside which a cutting head 2 is installed to cut the metal sheet. An operating plate 3 is located below the cutting head 2. When the metal sheet cutting equipment is in use, the metal sheet is placed on top of the operating plate 3. An automatic feeding device is installed on top of the operating plate 3. When it is necessary to feed the metal sheet cutting equipment, the automatic feeding device automatically feeds the cutting equipment. The automatic feeding device includes a slider 4, a first horizontal plate 5, a storage box 6, a first column 7, a first rotating roller 8, a first cover 9, a first hydraulic cylinder 10, a second rotating roller 11, a second column 28, and a second motor 27. The slider 4 is slidably engaged with the inner wall of the operating plate 3, and the top of the slider 4 is fixedly connected to the first horizontal plate 5. The slider 4 moves the first horizontal plate 5. A storage box 6, fixedly connected to the top of the operating plate 3, is located on the top of the first horizontal plate 5. The storage box 6 has openings on both sides large enough for metal plates to pass through. The storage box 6 stores the metal plates. The first horizontal plate 5 passes through the bottom opening of the storage box 6 and is inserted into the side of the storage box 6 away from the cutter head 2. The first horizontal plate 5 pushes the metal plates out of the storage box 6. A first column 7, fixedly connected to the bottom of the inner wall of the housing 1, is located on the side of the storage box 6 near the cutter head 2. A first roller 8 is rotatably connected to the top of the first column 7 via a pin. The first column 7 supports the first roller 8. A first cover 9, fixedly connected to the top of the inner wall of the housing 1, is located above the first roller 8. The inner wall of the first cover 9 is fixedly connected to… A first hydraulic cylinder 10 is connected to a first cover 9 to prevent dust and other debris from entering and damaging the first hydraulic cylinder 10. The output end of the first hydraulic cylinder 10 passes through the first cover 9 and is fixedly connected to a second column 28. The first hydraulic cylinder 10 drives the second column 28 to move. The outer wall of the second column 28 is rotatably connected to a second roller 11 via a pin. A second motor 27 is fixedly connected to the back of the outer wall of the second roller 11. The model of the second motor 27 is selected according to actual needs, as long as it meets the working requirements. First, the second motor 27 is connected to an external power supply. The second motor 27 drives the second roller 11 to rotate. The second motor 27 is fixedly connected to the outer wall of the second column 28 via a motor sleeve. When automatic feeding of the cutting equipment is required, the operator first loads the storage box 6 with... The metal sheet is pushed from the storage box 6 to the top of the first roller 8 by the slider 4, which drives the first horizontal plate 5. The first hydraulic cylinder 10 drives the second roller 11 to descend until it is in contact with the top of the metal sheet. The second motor 27 drives the second roller 11 to rotate, and the second roller 11 moves the metal sheet. The metal sheet cutting equipment described in this case can only process metal sheets with the same internal dimensions as the storage box 6. When processing smaller metal sheets, the metal sheet can be kept stable inside the storage box 6 by installing a limiting plate. The operator controls the rotation speed of the second motor 27 through the observation window to move the metal sheet. When the metal sheet is moved to the cutting position below the cutter head 2, the operator controls the second motor 27 to stop rotating.Cutter head 2 cuts the metal sheet at the designated cutting position;

[0026] In the specific implementation process, it is worth noting that the cutter head 2 cuts the metal sheet. When the metal sheet cutting equipment is in use, the metal sheet is placed on top of the operating plate 3. When the metal sheet cutting equipment needs to be loaded, the automatic loading device automatically loads the cutting equipment. The slider 4 drives the first horizontal plate 5 to move. The storage box 6 has openings on both sides large enough for the metal sheet to pass through. The storage box 6 stores the metal sheet. The first horizontal plate 5 pushes the metal sheet in the storage box 6 out of the storage box 6. The first column 7 supports the first rotating roller 8. The first cover 9 prevents dust, etc. When debris enters the first hydraulic cylinder 10 and causes it to be damaged, the second motor 27 is first connected to an external power source. The second motor 27 drives the second roller 11 to rotate. When automatic feeding of the cutting equipment is required, the operator first loads the metal sheet into the storage box 6. The slider 4 drives the first horizontal plate 5 to push the metal sheet in the storage box 6 to the top of the first roller 8. The first hydraulic cylinder 10 drives the second roller 11 to descend until it is in contact with the top of the metal sheet. The second motor 27 drives the second roller 11 to rotate. The second roller 11 moves the metal sheet, thus realizing automatic feeding of the metal sheet cutting equipment.

[0027] Furthermore, a lubrication mechanism is provided on the top of the housing 1. During automatic feeding of the metal sheet cutting equipment, the lubrication mechanism sprays stretching oil onto the surface of the metal sheet. The lubrication mechanism includes a photoelectric sensor 12, a relay 13, a support plate 14, an oil tank 15, an oil pump 16, a connecting pipe 17, and an oil nozzle 18. The photoelectric sensor 12 is fixedly connected to the top of the storage tank 6 on the side away from the cutter head 2. The photoelectric sensor 12 senses whether a metal sheet has entered the storage tank 6 through a light signal. A relay 13 is fixedly connected to the top of the outer wall of the housing 1 on the side of the photoelectric sensor 12 near the cutter head 2. The model of the relay 13 is selected according to actual needs, as long as it meets the working requirements. The relay 13 controls the circuit opening and closing of the oil pump 16. A support plate 14 is fixedly connected to the top of the outer wall of the housing 1 on the side of the relay 13 near the photoelectric sensor 12. A connecting pipe 17 is also provided on the side of the relay 13 near the cutter head 2. An oil tank 15 is fixedly connected to the top of the outer wall of the housing 1. The oil tank 15 contains stretching oil, which has high lubricity and can form a lubricating film on the surface of the metal sheet, reducing the friction of the metal sheet. An oil pump 16 is installed inside the oil tank 15. The oil pump 16 draws the stretching oil from the oil tank 15. The output end of the oil pump 16 is connected to a connecting pipe 17, which passes through a support plate 14. The support plate 14 supports the connecting pipe 17 and is fixedly connected to an oil nozzle 18. When the metal sheet enters the storage box 6, the photoelectric sensor 12 senses the change in light and converts the light signal into an electrical signal. The relay 13 receives the electrical signal and controls the oil pump 16 to draw the stretching oil through the control circuit. The stretching oil is sprayed onto the surface of the metal sheet through the connecting pipe 17 and the oil nozzle 18. The relay 13 controls the oil pump 16 to stop through the control circuit until the metal sheet enters the storage box 6 again.

[0028] In the specific implementation process, it is worth noting that when the metal sheet cutting equipment automatically feeds the material, the lubrication mechanism sprays stretching oil onto the surface of the metal sheet. The photoelectric sensor 12 senses whether a metal sheet has entered the storage tank 6 through light signals. The model of the relay 13 is selected according to actual needs, as long as it meets the requirements. The relay 13 controls the circuit opening and closing of the oil pump 16. The oil tank 15 contains stretching oil, which has high lubricity and can form a lubricating film on the surface of the metal sheet, reducing the friction of the metal sheet. The oil pump 16 draws the stretching oil from the oil tank 15. The support plate 14 supports the connecting pipe 17. When the metal sheet enters the storage tank 6, the photoelectric sensor 12 senses the change in light and converts the light signal into an electrical signal output. The relay 13 receives the electrical signal and controls the oil pump 16 to draw the stretching oil through the control circuit. The stretching oil is sprayed onto the surface of the metal sheet through the nozzle 18 via the connecting pipe 17. The relay 13 controls the oil pump 16 to stop through the control circuit until the metal sheet enters the storage tank 6 again, thus achieving the lubrication of the metal sheet.

[0029] Furthermore, a push switch 19 is fixedly connected in a groove on the inner wall of the storage box 6 near the cutter head 2. When the push switch 19 is triggered, it transmits an electrical signal to the relay 13. When the relay 13 receives electrical signals from both the push switch 19 and the photoelectric sensor 12, the relay 13 controls the circuit to open. An inclined plate 20 is provided on the side of the push switch 19 away from the cutter head 2. The inclined plate 20 is rotatably connected to the inner wall of the storage box 6 via a pin. When the metal plate falls from the top of the storage box 6, the metal plate presses the inclined plate 20 to rotate around the pin and press the push switch 19.

[0030] In the specific implementation process, it is worth noting that after the push switch 19 is triggered, it transmits an electrical signal to the relay 13. When the relay 13 receives the electrical signals from both the push switch 19 and the photoelectric sensor 12, the relay 13 controls the circuit. When the metal plate falls from the top of the storage box 6, the metal plate presses the inclined plate 20 to rotate around the pin shaft and presses the push switch 19, thus realizing further control of the relay 13.

[0031] Specifically, when automatic feeding of the cutting equipment is required, the operator first loads metal sheets into the storage box 6. The slider 4 drives the first horizontal plate 5 to push the metal sheets in the storage box 6 to the top of the first rotating roller 8. The first hydraulic cylinder 10 drives the second rotating roller 11 to descend until it is in contact with the top of the metal sheet. Then, the second motor 27 is connected to an external power supply, and the second motor 27 drives the second rotating roller 11 to rotate. The second rotating roller 11 moves the metal sheet. When the metal sheet enters the storage box 6, the photoelectric sensor 12 senses the change in light and converts the light signal into an electrical signal. When the metal sheet falls from the top of the storage box 6, the metal sheet presses the inclined plate 20 to rotate around the pin and presses the button switch 19. After the button switch 19 is triggered, it transmits an electrical signal to the relay 13. When the relay 13 receives the electrical signals from the button switch 19 and the photoelectric sensor 12 at the same time, it controls the oil pump 16 to draw stretching oil through the control circuit. The stretching oil is sprayed onto the surface of the metal sheet through the connecting pipe 17 and the spray nozzle 18. The relay 13 controls the oil pump 16 to stop through the control circuit until the metal sheet enters the storage box 6 again.

The outer wall of the second horizontal plate 21 away from the cutter head 2 is rotatably connected to the connecting rod 22 through a pin. The connecting rod 22 drives the second horizontal plate 21 to move. The bottom of the outer wall of the connecting rod 22 is rotatably connected to the cam 23 through a pin. The cam 23 drives the connecting rod 22 to rotate around the cam 23. The outer wall of the cam 23 is fixedly connected to the first motor 24. The model of the first motor 24 is selected according to actual needs, as long as it meets the working requirements. First, the first motor 24 is connected to an external power supply. The first motor 24 drives the cam 23 to rotate. The first motor 24 is fixedly connected to the bottom of the inner wall of the housing 1 through a motor sleeve. When it is necessary to automatically feed the metal plate, the operator first turns on the first motor 24. The first motor 24 drives the cam 23 to rotate. The cam 23 drives the connecting rod 22 to move. The connecting rod 22 drives the second horizontal plate 21 to move. The second horizontal plate 21 drives the slider 4 to move.

[0033] In the specific implementation process, it is worth noting that the second horizontal plate 21 drives the slider 4 to move, the connecting rod 22 drives the second horizontal plate 21 to move, and the cam 23 drives the connecting rod 22 to rotate around the cam 23. The model of the first motor 24 is selected according to actual needs, as long as it meets the working requirements. First, the first motor 24 is connected to an external power supply.

[0034] Furthermore, a second cover 25 is fixedly connected to the top of the inner wall of the housing 1 on the side away from the first cover 9.
