Description

Technical Field

[0001] This application relates to the field of stamping equipment technology, specifically to a feeding device for stamping equipment. Background Technology

[0002] Stamping equipment is essentially what is commonly referred to as a press, and it is the core equipment in the stamping process. The press applies strong pressure to drive the mold to perform punching, bending, stretching, and forming operations on materials such as metal sheets and strips, processing the raw materials into the required shapes and sizes. During the operation of stamping equipment, a feeding device is needed to transport the metal materials, working in conjunction with the stamping equipment to complete the automatic stamping operation.

[0003] However, if the material shifts during the feeding process, or if the material itself has uneven defects such as bending or local warping, it will affect the stamping quality and cause mold wear, reducing the mold life. Therefore, a feeding device for stamping equipment is proposed. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a feeding device for stamping equipment, which has the advantages of being able to stretch, straighten, and level the material during the feeding process, making the material surface flat and the internal stress uniform, providing a stable material foundation for subsequent stamping, and also limiting the material to prevent displacement during the feeding process, thus ensuring the quality of subsequent stamping. This solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a feeding device for a stamping equipment, comprising a stamping table, a first base fixedly connected to the upper surface of the stamping table, a first straightening roller rotatably connected inside the first base, a bracket fixedly connected to the outer surface of the stamping table, a hydraulic cylinder fixedly connected to the upper surface of the bracket, a second base fixedly connected to the output end of the hydraulic cylinder, a second straightening roller rotatably connected inside the second base, a lower die fixedly connected to the upper surface of the stamping table, and a first straightening roller rotatably connected to the upper surface of the stamping table. The three bases have two conveying rollers rotatably connected inside the third base, and a conveyor belt is driven between the two conveying rollers. The first base and the third base are located on both sides of the lower mold. The top of the outer circumferential surface of the first straightening roller and the upper surface of the conveyor belt are flush with the upper surface of the lower mold. A frame is fixedly connected to the upper surface of the stamping table. A lead screw is rotatably connected inside the frame. Two threaded tubes are threadedly connected to the outer circumferential surface of the lead screw. A connecting plate is fixedly connected to the outer circumferential surface of each threaded tube. A limit plate is fixedly connected to the upper surface of each connecting plate.

[0007] The above solution addresses the issue that material misalignment or unevenness defects such as bending or local warping during the feeding process can affect stamping quality. By setting equidistant first and second straightening rollers, the material can be straightened and leveled during feeding, resulting in a smooth surface and uniform internal stress. This provides a stable material foundation for subsequent stamping. The rotation of the lead screw, driven by the threaded tube, moves the connecting plate and limiting plate, effectively limiting the material's edge and preventing misalignment during feeding, thus ensuring subsequent stamping quality.

[0008] Furthermore, a stamping device is fixedly connected to the back of the stamping table, a drive module is fixedly connected inside the stamping device, and an upper mold is fixedly connected to the bottom of the drive module.

[0009] By integrating the stamping equipment with the drive module, the upper die can be automatically driven, thereby completing the stamping operation.

[0010] Furthermore, adjacent first straightening rollers are connected by sprockets and chains, one end of one of the first straightening rollers is equipped with a motor, adjacent second straightening rollers are connected by sprockets and chains, one end of one of the second straightening rollers is equipped with a motor, and one of the conveying rollers and one of the first straightening rollers are connected by sprockets and chains.

[0011] Through the above scheme, the sprocket and chain drive of the first and second straightening rollers ensures that the straightening rollers rotate synchronously, improving the consistency of the straightening effect. The transmission connection between the conveying roller and the first straightening roller realizes the linkage between straightening and conveying, simplifies the equipment structure, reduces energy consumption, and improves production continuity.

[0012] Furthermore, four guide rods are fixedly connected to the upper surface of the second base, and the outer circumferential surface of the guide rods is slidably inserted into the interior of the bracket.

[0013] With the above scheme, the guide rod is slidably inserted into the bracket, providing stable guidance for the lifting and lowering of the second base, preventing deviation during the straightening process, ensuring the precise cooperation between the second straightening roller and the first straightening roller, and improving the straightening accuracy.

[0014] Furthermore, the second straightening roller is located above the first straightening roller and is staggered with the first straightening roller.

[0015] With the above scheme, the second straightening roller is staggered with the first straightening roller, which can perform multiple alternating bending and straightening of the strip, effectively eliminating the original curvature and residual stress of the strip, improving the straightening quality, and meeting the requirements of high-precision stamping.

[0016] Furthermore, the lead screw is a bidirectional threaded rod, and handwheels are fixedly connected to both ends of the lead screw.

[0017] The above scheme achieves synchronous opposite or reverse movement of two threaded tubes by rotating the threads in opposite directions, thereby quickly adjusting the spacing of the limit plates to meet the limit requirements of strips of different widths. The handwheel design facilitates manual operation of the screw rod to adjust the position of the limit plates, making the operation simple and intuitive and improving the flexibility of the equipment.

[0018] Furthermore, the frame has limiting holes inside, and the outer surface of the connecting plate is slidably connected to the frame through the limiting holes.

[0019] The above solution involves creating limiting holes inside the frame to restrict the movement direction of the connecting plate, preventing the limiting plate from shifting or shaking during adjustment and improving the stability of the limiting plate's movement.

[0020] Furthermore, a collection box is provided on one side of the stamping table, and the collection box is located below the conveyor belt.

[0021] With the above solution, the collection box is located below one side of the conveyor belt, which can automatically collect the waste material after stamping, reduce the amount of manual cleaning, keep the production site clean, and improve production efficiency.

[0022] Beneficial effects

[0023] The feeding device of this stamping equipment, by setting up a first straightening roller and a second straightening roller arranged at equal intervals, can straighten and level the material during the feeding process, making the material surface flat and the internal stress uniform, providing a stable material foundation for subsequent stamping. When the lead screw rotates, it drives the connecting plate and the limiting plate to move and retract under the action of the threaded tube, which can limit the edge of materials of different sizes, effectively preventing the material from deviating during the feeding process and ensuring the quality of subsequent stamping. The second base is driven by a hydraulic cylinder to lift and lower, which can adjust the longitudinal distance between the first straightening roller and the second straightening roller, thereby performing leveling operations on materials of different thicknesses, improving the flexibility and practicality of the device. By setting the top of the first straightening roller and the upper surface of the conveyor belt to be flush with the upper surface of the lower die, the material is kept horizontal at all times during the stamping process, further ensuring the stamping quality.

The drive connection between the conveying roller 10 and the first straightening roller 3 realizes the linkage between straightening and conveying, simplifies the equipment structure, reduces energy consumption, and improves production continuity.

[0035] Please see Figure 1 , Figure 3 and Figure 4 Four guide rods 20 are fixedly connected to the upper surface of the second base 6.

[0040] In this embodiment, a feeding device for a stamping equipment, by setting an equidistant first straightening roller 3 and a second straightening roller 7, can straighten and level the material during the feeding process, making the material surface flat and the internal stress uniform, providing a stable material foundation for subsequent stamping. When the lead screw 13 rotates, it drives the connecting plate 15 and the limiting plate 16 to move and retract under the action of the threaded tube 14, which can limit the edges of materials of different sizes, effectively preventing the material from shifting during the feeding process and ensuring the quality of subsequent stamping. The hydraulic cylinder 5 drives the second base 6 to lift and lower, which can adjust the longitudinal distance between the first straightening roller 3 and the second straightening roller 7, thereby performing leveling operations on materials of different thicknesses, improving the flexibility and practicality of the device. By setting the top of the first straightening roller 3 and the upper surface of the conveyor belt 11 to be flush with the upper surface of the lower die 8, the material is kept horizontal during the stamping process, further ensuring the stamping quality.

[0041] It should be noted that the outer circumferential surfaces of the handwheels at both ends of the lead screw 13 are provided with anti-slip protrusions, which facilitates the rotation of the lead screw 13 through the handwheels, and thus adjusts the spacing of the limit plates 16 according to the size of the material.

[0042] The working principle of the above embodiments is as follows:

[0043] During the stamping operation, the material is placed between the first straightening roller 3 and the second straightening roller 7 through the upper surface of the frame 12. The drive motors at one end of one of the first straightening rollers 3 and one of the second straightening rollers 7 are activated, causing the first straightening roller 3 and the second straightening roller 7 to rotate synchronously under the action of sprockets and chains. This drives the material forward for feeding. During the material movement, it is repeatedly straightened and pressed by the staggered first straightening rollers 3 and 7, eliminating the original curvature and residual stress, ensuring a smooth material surface and uniform internal stress, and guaranteeing the subsequent stamping quality. The top of the first straightening roller 3 and the upper surface of the conveyor belt 11 are set to be flush with the upper surface of the lower die 8, so that the material is straightened during the stamping process. The device remains level throughout, further optimizing the stamping effect. The conveying roller 10 is driven by one of the first straightening rollers 3 via a sprocket and chain, enabling the unloading of stamping waste material while feeding. The rotatable lead screw 13, under the action of the threaded tube 14, drives the connecting plate 15 and the limiting plate 16 to move and retract. The spacing of the limiting plate 16 is adjusted according to the size of the material, thereby limiting the edges of materials of different sizes and preventing deviation during material conveying. The hydraulic cylinder 5 can be activated to drive the second base 6 to lift and lower, adjusting the longitudinal spacing between the first straightening roller 3 and the second straightening roller 7, thereby performing leveling operations on materials of different thicknesses and improving the flexibility and practicality of the device.

[0044] 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.
