Description

Technical Field

[0001] This application relates to the field of machining, and in particular to a feeding device for steel sheet stamping. Background Technology

[0002] A feeding device for steel sheet stamping is a feeding equipment used in steel sheet stamping production, which aims to improve production efficiency, ensure stamping quality, and adapt to the needs of large-scale and continuous production.

[0003] Traditional steel sheet stamping feeding devices mainly focus on the stability of material transmission. However, in actual industrial production, the surface of steel sheet raw materials is often covered with impurities such as oil and metal shavings. If they enter the stamping process directly without effective cleaning, these contaminants will cause accelerated mold wear, indentations or burrs on the surface of the stamped parts, and even quality problems such as mold jamming. Utility Model Content

[0004] To address the issue of steel sheets not being effectively cleaned before stamping, this application provides a feeding device for steel sheet stamping.

[0005] The steel sheet stamping feeding device provided in this application adopts the following technical solution:

[0006] A feeding device for steel sheet stamping includes a base, an isolation plate for guiding cleaning liquid is fixedly connected inside the base, and a collection tank for collecting waste liquid is fixedly connected and communicated to the bottom surface of the base.

[0007] The top surface of the base is provided with an auxiliary mechanism for pre-stamping the steel sheet.

[0008] By adopting the above technical solution, the base serves as the supporting foundation of the entire device, bearing all functional components (such as auxiliary mechanisms, conveyor rollers, etc.) and providing a stable operating platform. The isolation plate is fixed inside the base, with pores distributed on its surface to allow the cleaning fluid to flow to the collection tank below. The collection tank is connected to the bottom surface of the base to collect the waste liquid (containing impurities and cleaning fluid) flowing from the isolation plate. The auxiliary mechanism is used to brush the steel sheets.

[0009] Preferably, the auxiliary mechanism includes an auxiliary frame one fixedly connected to the top surface of the base, an auxiliary frame two fixedly connected to the top surface of the base, and a motor fixedly connected inside the auxiliary frame two.

[0010] By adopting the above technical solution, the auxiliary frame 1 is fixed on the top surface of the base, supporting the rotating column 2 and the synchronous pulley 2, forming part of the transmission system. The auxiliary frame 2 is fixed on the top surface of the base, and the motor and rotating column 1 are installed inside, providing structural support for power output and transmission. The motor serves as a power source, driving the rotating column 1 to rotate.

[0011] Preferably, the output end of the motor is fixedly connected to a rotating column that is rotatably connected to the auxiliary frame 2, a synchronous pulley is fixedly connected to the outer surface of the rotating column, and a bevel gear set is fixedly connected to the top surface of the rotating column.

[0012] By adopting the above technical solution, the rotating column one is driven to rotate by a motor, and the power is transmitted to the connecting column through a bevel gear set. The synchronous pulley one is fixed on the outer surface of the rotating column one and is connected to the synchronous pulley two through a synchronous toothed belt. The bevel gear set converts the horizontal rotation of the rotating column one into a horizontal rotation in the same plane orthogonal direction, driving the connecting column.

[0013] Preferably, a support plate is fixedly connected to the top surface of the base in a symmetrical manner, and a connecting column is fixedly connected to the end of the bevel gear set away from the rotating column, which is rotatably connected to the auxiliary frame and the support plate. A roller brush is fixedly connected to the side of the connecting column away from the bevel gear set, which is rotatably connected to the support plate.

[0014] By adopting the above technical solution, the support plate is symmetrically fixed on the top surface of the base, supporting the connecting column and allowing it to rotate. The connecting column passes through the auxiliary frame and the support plate, realizing the transmission of power from the horizontal to the vertical direction, driving the roller brush to rotate. The roller brush is driven to rotate through the connecting column, directly contacting the surface of the steel sheet to brush away dirt and impurities.

[0015] Preferably, a rotating column 2 is rotatably connected through the interior of the auxiliary frame 1, a synchronous pulley 2 is fixedly connected to the outer surface of the rotating column 2, a synchronous toothed belt is meshed between the synchronous pulley 2 and the synchronous pulley 1, and an auxiliary block is rotatably connected to the top surface of the rotating column 2.

[0016] By adopting the above technical solution, a synchronous pulley is fixed on the outer surface of the rotating column two, and an auxiliary block is connected to the top surface. The synchronous pulley two ensures that the rotating column one and the rotating column two rotate synchronously, coordinates the transmission system, and transmits the power of the rotating column one to the rotating column two through the synchronous toothed belt to achieve synchronous rotation. The auxiliary block converts the rotational motion of the rotating column two into the reciprocating movement of the auxiliary block, which drives the piston rod to move.

[0017] Preferably, both sides of the auxiliary block are fixedly connected with sliding rods that are slidably connected to the top surface of the auxiliary frame, the base is symmetrically fixedly connected with a second support plate, and the inside of the second support plate is rotatably connected with a first cylinder.

[0018] By adopting the above technical solution, the slide rod is fixed on both sides of the auxiliary block and slidably connected to the top surface of the auxiliary frame to guide the reciprocating movement of the auxiliary block. The second support plate is symmetrically fixed on the top surface of the base, supporting the first cylinder and allowing it to rotate. The first cylinder is used to store cleaning fluid.

[0019] Preferably, the auxiliary block has a piston rod that is slidably adapted to the cylinder, the cylinder has an arc-shaped groove inside, and a sliding column that is slidably adapted to the arc-shaped groove is fixedly connected to the outer surface of the cylinder.

[0020] By adopting the above technical solution, the piston rod realizes the automatic spraying of cleaning liquid, and works in conjunction with the roller brush to clean the steel sheet. The sliding column and the arc groove cooperate to realize the small-angle swing of the cylinder, thereby realizing the dynamic adjustment of the spraying direction.

[0021] Preferably, a support frame is fixedly connected to the top surface of the base, a scraper is fixedly connected to one side of the support frame, a connecting block is symmetrically slidably connected inside the support frame, a roller is rotatably connected to the side of the connecting block away from the support frame, a second cylinder is fixedly connected inside the support frame, a cylinder that is slidably connected to the second cylinder is fixedly connected to one side of the connecting block, and a return spring sleeved on the outer surface of the cylinder and the second cylinder is fixedly connected between the support frame and the connecting block.

[0022] By adopting the above technical solution, the support frame provides support for the connecting block and the scraper. The scraper is used to scrape off the cleaning liquid residue on the surface of the steel plate. The roller directly contacts the steel sheet and cleans the surface of the steel sheet by rotating. The connecting block is used to support the roller. The cylinder is slidably connected inside the second cylinder to ensure the accuracy of the vertical adjustment of the roller. The reset spring provides elastic force so that the roller adapts to the change in the thickness of the steel sheet and maintains stable contact pressure.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By using a rotating column to simultaneously drive the roller brush to rotate and the piston rod to reciprocate, the mechanical brushing of dirt on the steel strip surface and the automatic spraying of cleaning liquid are carried out simultaneously. This integrated design simplifies the process flow, avoids the problems of requiring independent cleaning equipment and additional manual operation in traditional processes, and improves production efficiency.

[0025] 2. By utilizing the linkage design of the inner groove and piston rod of the cylinder, the cylinder can swing at an angle during the spraying of the cleaning liquid. This dynamic spraying method can expand the coverage area of ​​the cleaning liquid, make the cleaning liquid more evenly distributed on the surface of the steel belt, avoid waste caused by insufficient cleaning in some areas or excessive spraying, and improve the cleaning effect.

[0034] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0035] This application discloses a feeding device for steel sheet stamping.

[0037] In use, the rotation of the roller in the first transmission wheel 2 drives the steel sheet body 3 to move towards the second transmission wheel 4 and transports the steel sheet body 3 into the second transmission wheel 4. The second transmission wheel 4 then transports the steel sheet body 3 into the stamping mechanism.

[0038] Reference Figures 1-2An auxiliary mechanism is provided on the top surface of the base 1. The auxiliary mechanism includes an auxiliary frame 71 fixedly connected to the top surface of the base 1. The top surface of the base 1 is fixedly connected to the bottom surface of an auxiliary frame 72, and the auxiliary frame 72 is fixedly connected to and communicates with the auxiliary frame 71. The bottom surface of the inner wall of the auxiliary frame 72 is fixedly connected to the outer shell of the motor 73. A through hole is provided on the outer surface of the auxiliary frame 72 for heat dissipation of the motor 73. The output end of the motor 73 is fixedly connected to a rotating column 74, and the rotating column 74 is rotatably connected to the inner wall of the auxiliary frame 72 through a connecting plate. The outer surface of the rotating column 74 is fixedly connected to a synchronous pulley 75, which is located above the connecting plate, and the connecting plate does not interfere with the movement of the synchronous pulley 75. The side of the rotating column 74 away from the motor 73 is connected to a bevel gear. The base 1 is fixedly connected to the top surface of the base 1 and the two support plates 79. The two support plates 79 are symmetrically positioned. The steel plate body 3 is slidably connected between the two support plates 79. The opposite surfaces of the two support plates 79 can be provided with grooves to facilitate the sliding of the steel plate body 3 and to restrict the steel plate body 3 to prevent its position from shifting. One end of the bevel gear set 77 is fixedly connected to the connecting column 78. The connecting column 78 is located at the end away from the rotating column 74. The connecting column 78 is rotatably connected to the auxiliary frame 72 and the support plate 79. One side of the connecting column 78 is fixedly connected to the roller brush 710. The roller brush 710 is located at the side away from the bevel gear set 77. The roller brush 710 is rotatably connected inside the support plate 79. The steel plate body 3 is located directly below the roller brush 710.

[0039] In use, the motor 73 drives the rotating column 74 to rotate, the rotating column 74 drives the bevel gear set 77 fixedly connected to the rotating column 74 to rotate, the bevel gear set 77 drives the connecting column 78 fixedly connected to the bevel gear set 77 to rotate, the connecting column 78 drives the roller brush 710 fixedly connected to the connecting column 78 to rotate, and the rotation of the roller brush 710 brushes away oil stains, metal debris and other impurities on the surface of the steel sheet body 3.

[0040] Reference Figures 2-4The auxiliary frame 71 is rotatably connected to the rotating column 711. The outer surface of the rotating column 711 is fixedly connected to the synchronous pulley 712. The synchronous pulley 712 is located inside the auxiliary frame 71, and the synchronous toothed belt 76 meshes with the outer surfaces of the synchronous pulley 712 and the synchronous pulley 75. The top surface of the rotating column 711 is eccentrically connected to the auxiliary block 713. The auxiliary block 713 is hollow inside. Both sides of the auxiliary block 713 are fixedly connected to the slide rod 714, and the slide rod 714 is slidably connected to the top surface of the auxiliary frame 71. The top surface of the base 1 is fixedly connected to two support plates 717, and the positions of the two support plates 717 are symmetrical. The steel sheet body 3 is slidably connected between the two support plates 717, and the opposite surfaces of the two support plates 717 can be provided with grooves to facilitate the sliding of the steel sheet body 3 and to restrict the steel sheet body 3 to prevent its position from shifting. The inner surface of the support plate 717... The wall is rotatably connected to the cylinder 716. Several nozzles are fixed on the arc surface of the cylinder 716. The nozzle model is Lechler460.848.1A (fan-shaped nozzle). 6-9 nozzles are evenly distributed along the axial direction on the surface of the cylinder 716. The cylinder 716 is filled with cleaning fluid and can be connected to an external automatic cleaning fluid injection device. The inner wall of the auxiliary block 713 is slidably connected to the piston rod 715, and the piston rod 715 is slidably connected inside the cylinder 716. An arc-shaped groove 719 is opened on the inner wall of the cylinder 716 near the opening. The outer surface of the cylinder 716 is fixedly connected to the sliding column 718, and the sliding column 718 is slidably connected inside the arc-shaped groove 719. A pressure amplification mechanism can be added between the auxiliary block 713 and the piston rod 715. A lever fulcrum is set inside the auxiliary block 713 with a lever ratio of 1:3. A sealing ring (material: fluororubber) is installed at the end of the piston rod 715.

[0041] In use, the rotation of synchronous pulley 75 drives the synchronous toothed belt 76 meshing with it to rotate. The rotation of synchronous toothed belt 76 drives synchronous pulley 712 meshing with it to rotate. The rotation of synchronous pulley 712 drives rotating column 711, which is fixedly connected to it, to rotate. The rotation of rotating column 711 causes auxiliary block 713, which is slidably connected to it, to move, and also causes slide rod 714, which is fixedly connected to auxiliary block 713, to slide. Since slide rod 714 slides on the top surface of auxiliary frame 71, it restricts the displacement of auxiliary block 713, allowing auxiliary block 713 to move. The 13 can move horizontally. The horizontal movement of the auxiliary block 713 drives the piston rod 715, which is slidably connected to the auxiliary block 713, to reciprocate inside the cylinder 716. When the piston rod 715 moves, it drives the sliding column 718, which is fixedly connected to the piston rod 715, to move together. The sliding column 718 moves inside the arc groove 719, thereby causing the cylinder 716 to deflect. That is, through the reciprocating movement of the piston rod 715, the cleaning liquid inside the cylinder 716 is sprayed onto the surface of the steel sheet body 3 through the nozzle. Furthermore, through the swinging of the cylinder 716, the cleaning liquid is dynamically sprayed, expanding the coverage area of ​​the cleaning liquid.

[0042] Reference Figures 5-6 The top surface of the base 1 is fixedly connected to the support frame 720. A scraper 721 is fixedly connected to the side of the support frame 720 near the second conveyor wheel 4. The support frame 720 is located between the first conveyor wheel 2 and the steel sheet body 3. Two connecting blocks 724 are slidably connected to the inner wall of the support frame 720. A groove can be opened on the inner wall of the support frame 720 to facilitate the sliding of the steel sheet body 3 and to restrict the steel sheet body 3 to prevent its position from shifting. One side of the connecting block 724 is rotatably connected to the roller 722. The roller 722 is located on the side away from the support frame 720 and above the steel sheet body 3. The inner wall of the support frame 720 is fixedly connected to the second cylinder 723. The top surface of the connecting block 724 is fixedly connected to the cylinder 725, and the cylinder 725 is slidably connected inside the second cylinder 723. The inner wall of the second cylinder 723 may be provided with an annular groove. The end of the cylinder 725 may be fitted with a limiting ring. When the cylinder 725 slides to its maximum stroke, the limiting ring engages with the annular groove to limit the movement. The top surface of the inner wall of the support frame 720 is fixedly connected to a return spring 726. The end of the return spring 726 away from the support frame 720 is fixedly connected to the connecting block 724, and the return spring 726 is sleeved on the outer surface of the cylinder 725 and the second cylinder 723. In the initial state, the return spring 726 is in a compressed state.

[0043] During use, when the first conveyor wheel 2 transports the cleaned steel sheet body 3 to the second conveyor wheel 4, it passes through the roller 722. Since the return spring 726 is in a compressed state in the initial state, the return spring 726 will push the connecting block 724 to move closer to the steel sheet body 3. When the roller 722 contacts the steel sheet body 3, the roller 722 will rotate due to friction, thereby cleaning the surface of the cleaned steel sheet body 3. Then, the scraper 721 will scrape off the surface of the steel sheet body 3 to ensure that there is no residual cleaning liquid on the surface of the steel sheet body 3.

[0044] Among them, motor 73 is a Schneider Lexium 05 series servo motor, which is selected with a rated speed of ≈60RPM and a rated torque of ≥5N·m. The auxiliary frame 2 72 is equipped with a power supply and PLC control system. The PLC control system is electrically connected to the auxiliary frame 2 72. The start and stop of motor 73 are controlled by the PLC control system. The connecting wire of motor 73 is connected to the switch. When the switch is pressed, the user controls the rotation of motor 73 through the PLC control system.

[0045] In this device, the return spring 726 uses the calculation formula for alloy springs: F = kx, where F is the external force on the spring, k is the spring constant, N / m, and x is the deformation of the spring, m. The elastic force of the alloy spring is then calculated so that it can be used in this device.

[0046] The implementation principle of a steel sheet stamping feeding device according to an embodiment of this application is as follows:

[0047] In use, the rotation of the roller in conveyor wheel 2 drives the steel sheet body 3 to move closer to conveyor wheel 4. When the steel sheet body 3 is transported between support plates 79, motor 73 drives rotating column 74 to rotate. The rotation of rotating column 74 drives bevel gear set 77, connecting column 78 and roller brush 710 to rotate. The rotation of roller brush 710 washes oil stains, metal debris and other impurities from the surface of steel sheet body 3. The rotation of rotating column 74 drives synchronous pulley 75 to rotate. The rotation of synchronous pulley 75 drives synchronous toothed belt 76, synchronous pulley 712 and rotating column 711 to rotate. The rotation of rotating column 711 drives piston rod 71. 5. The cylinder 716 reciprocates inside, thereby spraying the cleaning fluid inside the cylinder 716 onto the surface of the steel sheet body 3 through the nozzle. The oscillation of the cylinder 716 achieves dynamic spraying of the cleaning fluid, expanding the coverage area of ​​the cleaning fluid. Subsequently, the steel sheet body 3 moves into the support frame 720. The surface of the cleaned steel sheet body 3 is cleaned by the rotation of the roller 722. Then, the surface of the steel sheet body 3 is scraped by the scraper 721 to ensure that there is no residual cleaning fluid on the surface of the steel sheet body 3. Finally, the steel sheet body 3 is transported into the conveyor wheel 4, and the conveyor wheel 4 transports the steel sheet body 3 into the stamping mechanism for stamping.

[0048] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
