DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the embodiment of the present application more clear, the technical scheme of the present application will be described clearly and completely below in combination with the embodiment.

[0020] Embodiment 1: The present application provides a guide plate machine for steel plate production and processing, like Figure 1 and Figure 2As shown, it includes a leveling device 1, which levels the steel strip 3 to be stamped. The leveling device 1 includes: a housing 2, a steel strip 3, a transmission roller 4, and a limiting roller 5. The housing 2 has two opposing support bars 201 fixed at its inlet. Multiple transmission rollers 4 are arranged parallel to each other between the two support bars 201. The limiting roller 5 is limited between the two support bars 201 by a movable part, which includes: a square rod 6, a side plate 7, a first nut 8, a bottom roller 9, and a top roller 10. The limiting roller 5 is located at the top of the square-round rod 6. Both ends of the square-round rod 6 are fixed with a slide. The slide slides on the surface of the frame bar 201. Two vertical side plates 7 are sleeved on the surface of the square-round rod 6. The top of the side plate 7 is movably sleeved on the surface of the limiting roller 5, and the bottom of the side plate 7 is movably sleeved on the surface of the square-round rod 6. At this time, the bottom of the side plate 7 is provided with a square-round groove corresponding to the square-round rod 6. The outer side of the side plate 7 is provided with a first nut 8, which is screwed onto the square-round rod 6. At this time, the steel strip 3 enters the interior of the leveling device 1 through the space between the limiting roller 5 and the square-round rod 6.

[0021] The outer casing 2 has two bottom rollers 9 arranged in parallel. The top roller 10 is provided on the top of the bottom rollers 9 and is installed inside the outer casing 2 by means of a lifting part.

[0022] Specifically, rotating the first nut 8 causes it to rotate on the surface of the square-round rod 6. The moving first nut 8 pushes the side plate 7 to slide on the surface of the square-round rod 6. At this time, the top of the side plate 7 slides on the surface of the limiting roller 5, and the two opposite side plates 7 move closer to each other. Since the bottom of the side plate 7 is slidably sleeved on the surface of the square-round rod 6 using the square-round groove, the side plate 7 is always set vertically until the inner side of the side plate 7 is in contact with the side of the steel strip 3. At this time, the steel strip 3 to be leveled enters the interior of the outer shell 2 through the space between the two side plates 7, preventing the steel strip 3 from swinging arbitrarily at the input port of the leveling device 1.

[0023] The steel strip 3 moves between the limiting roller 5 and the square rod 6 to the top of multiple transmission rollers 4 to prevent the steel strip 3 from tilting too much at the input of the leveling equipment 1. The moving steel strip 3 causes the transmission rollers 4 to rotate between the two support bars 201 until the steel strip 3 moves between the top roller 10 and the bottom roller 9. At this time, the two top rollers 10 cooperate with the two bottom rollers 9 to level the steel strip 3, making the top and bottom surfaces of the steel strip 3 flat. At this time, the leveling equipment 1 has finished leveling the steel strip 3 to be stamped.

[0024] Two support bars 201 are arranged opposite each other, and the transmission roller 4 is rotated and sleeved on the surface of the insertion rod 14. The insertion rod 14 horizontally passes through the two support bars 201, and both ends of the insertion rod 14 are spirally sleeved with fastening sleeves 15.

[0025] If the inclination angle of the steel belt 3 is not large, the bottom surface of the steel belt 3, which is limited by the limiting roller 5, contacts the surface of multiple transmission rollers 4. Since the two fastening sleeves 15 limit the insertion rod 14, the transmission roller 4 rotates on the surface of the insertion rod 14, and the steel belt 3 is smoothly transmitted into the leveling equipment 1 by multiple transmission rollers 4.

[0026] In this embodiment, the steel strip 3 is limited by the square rod 6 and the limiting roller 5 to prevent the steel strip 3 from tilting too much at the input port of the leveling device 1. The rotating first nut 8 is used to make the inner side of the side plate 7 fit against the side of the steel strip 3 to prevent the steel strip 3 from swinging arbitrarily at the input port of the leveling device 1, so that the steel strip 3 to be leveled can smoothly pass between the two side plates 7 and enter the interior of the outer shell 2.

[0027] To ensure that the top roller 10 and bottom roller 9 flatten the steel strip 3, a lifting mechanism is used to move the top roller 10 up and down. Figure 2 and Figure 3 In the middle, the lifting part includes: a vertical rod 11, a retaining frame 12, and a second nut 13; the vertical rod 11 is set vertically, the top end of the vertical rod 11 penetrates the top surface of the outer shell 2, the bottom end of the vertical rod 11 is inside the outer shell 2, the retaining frame 12 is fixed at the bottom end of the vertical rod 11, and both ends of the top roller 10 are provided with protrusions corresponding to the retaining frame 12, the retaining frame 12 is sleeved on the surface of the protrusions, and the second nut 13 is sleeved on the surface of the vertical rod 11, and the second nut 13 is inside the outer shell 2.

[0028] Specifically, two parallel bottom rollers 9 are arranged inside the outer casing 2. At this time, the bottom rollers 9 are rotated and locked inside the outer casing 2. A top roller 10 is arranged directly above the bottom rollers 9. The length of the top roller 10 is less than the length of the bottom rollers 9. Both ends of the top roller 10 are fixed with protruding rods. At this time, the locking frame 12 is sleeved on the surface of the protruding rods. At this time, the vertical rod 11 at the top of the locking frame 12 vertically penetrates the top surface of the outer casing 2.

[0029] Pull the vertical rod 11 upwards. The upward movement of the vertical rod 11, along with the retaining frame 12, causes the top roller 10 to move upwards synchronously until the top surface of the second nut 13 is in contact with the inner top surface of the outer casing 2. When the steel strip 3 is at the top of the bottom roller 9, release the tension applied to the vertical rod 11. The top roller 10, along with the retaining frame 12, causes the vertical rod 11 to move downwards. Since the vertical rod 11 vertically penetrates the top surface of the outer casing 2, the top roller 10 moves downwards vertically until it contacts the top surface of the steel strip 3. Rotate the second nut 13. The rotating second nut 13 moves upwards on the surface of the vertical rod 11 until the top surface of the second nut 13 abuts against the inner top surface of the outer casing 2. The second nut 13 and the vertical rod 11 cooperate to limit the retaining frame 12. At this time, both opposing retaining frames 12 use protruding rods to cause the top roller 10 to press against the top surface of the steel strip 3. The rotating top roller 10 and the bottom roller 9 cooperate to flatten the steel strip 3.

[0030] In this embodiment, the second nut 13 is screwed into the vertical rod 11, and the second top surface abuts against the inner top surface of the outer shell 2, so that the top roller 10 and the bottom roller 9 can cooperate to flatten the steel strips 3 of different thicknesses.

[0031] To accommodate the tilt angle of the steel strip 3, the square-round rod 6 between the two carriages and the limiting roller 5 are used to limit the steel strip 3. Figure 2 , Figure 4 andFigure 5 In the frame, both ends of the square-round rod 6 are fixed with sliding rods 16. The surface of the frame bar 201 is provided with a sliding groove 202 corresponding to the sliding rod 16. The sliding groove 202 coincides with the center line of the frame bar 201. A semi-circular plate 17 is fixed to the outer end of the sliding rod 16. The sliding rod 16 causes the bottom surface of the semi-circular plate 17 to slide on the top surface of the frame bar 201. The outer end of the semi-circular plate 17 is connected to the outer end of the sliding rod 16 by a connecting plate, and the semi-circular plate 17 and the sliding rod 16 are integrated into a carriage by a connecting rod.

[0032] A locking block 18 is provided on the inner side of the semicircular plate 17. A bottom groove 171 corresponding to the locking block 18 is provided on the bottom surface of the semicircular plate 17, and a slot 181 is opened on the bottom surface of the locking block 18. A plurality of locking teeth 19 corresponding to the slot 181 are provided on the top surface of the frame bar 201. The outer side of the locking block 18 is connected by a moving rod 20, and the outer end of the moving rod 20 passes through the outer end of the semicircular plate 17. Two opposing locking edges 21 are fixed on the outer side of the semicircular plate 17. A rotating sleeve 22 is rotatably sleeved on the outer side of the two locking edges 21, and the rotating sleeve 22 is spirally sleeved on the outer end of the moving rod 20.

[0033] Specifically, when the rotating sleeve 22 is rotated, the carriage uses two retaining edges 21 to limit the rotating sleeve 22. The rotating sleeve 22 rotates on the surface of the moving rod 20. Since the inner end of the moving rod 20 is limited between the semicircular plate 17 and the frame bar 201 by the locking block 18, the rotating sleeve 22 and the moving rod 20 are screwed together, causing the moving rod 20 to drive the locking block 18 to move. The moving locking block 18 gradually approaches the connecting plate of the carriage. At this time, the locking block 18 slides on the top of the retaining tooth 19 using the retaining groove 181 until the retaining groove 181 separates from the retaining tooth 19. At this time, the locking block 18 can no longer limit the carriage.

[0034] The slide is pushed to slide on the frame bar 201. The moving slide causes the slide rod 16 to move inside the slide groove 202, and the bottom surface of the semicircular plate 17 slides on the top surface of the frame bar 201. The moving slide uses the square and round rod 6 to make the side plate 7 and the limiting roller 5 move synchronously until the surface of the limiting roller 5 presses against the top surface of the steel strip 3, and the bottom surface of the steel strip 3 is in contact with the top surface of multiple transmission rollers 4. At this time, the rotating sleeve 22 is rotated in the opposite direction. The rotating sleeve 22 causes the locking block 18 at the inner end of the moving rod 20 to move away from the connecting plate. The locking block 18 is slidably engaged with the top of the locking tooth 19 by the slot 181. The semicircular plate 17 uses the bottom groove 171 to limit the top of the locking block 18, preventing the locking block 18 from rotating between the semicircular plate 17 and the frame bar 201.

[0035] In this embodiment, by rotating the rotating sleeve 22, the locking block 18 and the locking tooth 19 can be adjusted in real time, which makes it convenient to lock the slide at different positions on the frame bar 201, so that the steel strip 3 with different inclination angles can smoothly enter the interior of the outer shell 2.

[0036] Example 2: This invention also provides a production line for steel plate production and processing, in Figure 1 and Figure 2 The system includes: a loading rack 23, a feeder 24, an induction switch 25, a stamping device 26, a tilting platform 27, a transmission frame 28, a keel cold bending system 29, and a cutting device 30. The output end of the feeder 24 is equipped with the loading rack 23, and a steel strip coil is sleeved on the surface of the loading rack 23. The feeder 24 transmits the steel strip 3 from the steel strip coil to the leveling device 1 through the induction switch 25. After the leveling device 1 levels the steel strip 3, it punches the leveled steel strip 3 through the stamping device 26. An auxiliary frame 271 is set on one side of the tilting platform 27. The punched steel strip 3 is flipped to the top of the tilting platform 27 through the top of the auxiliary frame 271. The flipped steel strip 3 is transmitted to the input end of the keel cold bending system 29 through two transmission frames 28. After being cold-bent by the keel cold bending system 29, the steel strip 3 enters the cutting device 30. The cutting device 30 cuts the cold-bent steel strip 3. The cut steel strip 3 is the finished product that falls into the collection bin. The finished steel strip 3 is the steel plate.

[0037] Specifically, the steel strip coil is attached to the feeding rack 23. At this time, the feeder 24 uses the drive equipment to automatically convey the steel strip 3, ensuring continuous feeding. When the steel strip 3 contacts the induction switch 25, the conveying will stop. The steel strip passing through the induction switch 25 enters the leveling equipment 1 through the square and round rod 6 and the limiting roller 5. At this time, the leveling equipment 1 uses the top roller 10 and the bottom roller 9 to level the steel strip 3. The stamping equipment 26 punches the leveled steel strip 3. The stamping equipment 26 uses a mold to punch round holes, square holes and other shapes on the steel strip 3. The punching mold of the stamping equipment 26 will wear out during long-term operation, and a small number of burrs may appear on the surface of the steel strip 3. The side with burrs may be flipped over by the flipping platform 27 and the auxiliary frame 271. The flipped steel strip 3 is then transferred to the input end of the keel cold bending system 29 through two transmission frames 28. In the keel cold bending system 29, the reducer is driven by the motor to drive the roller assembly to rotate. The rotated steel strip 3 is fed into the roller assembly. The keel cold bending system 29 uses multiple roller assemblies to cold bend the steel strip 3 into shape. The formed steel strip 3 is then fed into the cutting device 30. The cutting device 30 cuts the cold-bent steel strip 3, and the cut steel strip 3 falls into the collection bin.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
