Description

Technical Field

[0001] This utility model belongs to the technical field of four-roll plate rolling machines, and particularly relates to a feeding mechanism for a four-roll plate rolling machine. Background Technology

[0002] A four-roll plate bending machine is a type of bending and straightening equipment. Its core function is to bend and shape metal sheets. It is widely used in many industries such as pressure vessels, pipe manufacturing, and shipbuilding. The core of the four-roll plate bending machine lies in the coordinated operation of the four rollers. With the help of an advanced hydraulic CNC system, it can accurately realize various motion modes such as upper roller fixing, lower roller lifting, and side roller tilting. This unique structural design gives it many practical functions: First, it has the ability to pre-bend the ends of the sheet metal, which can complete the bending process of the sheet metal ends without the need for additional equipment, effectively avoiding the cumbersome process of pre-bending the ends of the sheet metal required by traditional plate bending machines; Second, it has a wide range of applications. It can not only process workpieces with regular shapes such as circles and arcs, but also complete the forming process of conical workpieces and multi-curvature cylinders; In addition, it also has a rough leveling function, which can perform preliminary leveling of the metal sheet metal after bending and forming, further expanding the application scenarios of the equipment.

[0003] However, most existing four-roll plate rolling machines in the industry use manual feeding, where operators move the plates to be rolled to the equipment and align them. Manual operation makes it difficult to ensure that the steel plates are always fed in a straight line, which can easily lead to plate misalignment. Once the position of the steel plate deviates during feeding, the arc shape of the rolled workpiece will be inaccurate, which will not only affect the quality of the product, but also lead to material waste, increased production costs, and reduced production efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a feeding mechanism for a four-roll plate rolling machine, which solves the technical problem that most of the existing four-roll plate rolling machines in the industry use manual feeding, where operators carry the plate to be rolled to the equipment and perform alignment operations. Manual operation makes it difficult to ensure that the steel plate is fed in a straight line, which easily leads to plate deviation.

[0005] To achieve the above objectives, the main technical solutions adopted by this utility model include: A feeding mechanism for a four-roll plate bending machine includes a four-roll plate bending machine body, characterized in that it further includes a base and a lifting plate. Multiple guide columns are fixedly mounted on the top surface of the base. Two side plates are fixedly mounted on the top surface of the lifting plate. Multiple connecting blocks are fixedly mounted on the outer surface of each side plate. The guide columns are slidably connected within the connecting blocks. Multiple support shafts are rotatably mounted between the two side plates. Support rollers are fixedly mounted on the support shafts. Multiple guide rods are slidably connected within each side plate. Limiting plates are fixedly mounted at the inner ends of the multiple guide rods. A strip-shaped opening is opened within each side plate. A rack is fixedly mounted on the outer surface of each limiting plate, and the rack movably passes through the strip-shaped opening. A driving assembly is provided on the lifting plate, and the rack is driven by the driving assembly.

[0006] Furthermore, the drive assembly includes a dual-output-shaft servo motor. Two connecting plates are fixedly mounted on the outer surface of the side plate, and a rotating shaft is rotatably mounted inside the two connecting plates. A spur gear is fixedly mounted on the upper end of the rotating shaft, and the spur gear meshes with the rack. A driven bevel gear is fixedly mounted on the lower end of the rotating shaft. A main shaft is rotatably mounted inside the side plate, and an active bevel gear is fixedly mounted on the outer end of the main shaft. The two active bevel gears are symmetrical to each other, and the active bevel gear meshes with the driven bevel gear. The dual-output-shaft servo motor is fixedly mounted on the top surface of the lifting plate, and the two output shafts of the dual-output-shaft servo motor are respectively fixedly connected to one end of the two main shafts.

[0007] Furthermore, a servo cylinder is fixedly provided on the top surface of the base, and the telescopic end of the servo cylinder is fixedly connected to the bottom surface of the lifting plate.

[0008] Furthermore, a connecting rod is fixedly provided at the outer end of each of the guide rods, and the connecting rod is fixedly connected to the outer end of the rack.

[0009] Furthermore, the lower end of the limiting plate matches the shape of the support roller.

[0010] The beneficial effects of this utility model are: 1. The lifting plate can raise and lower the support rollers. The height of the support rollers can be adjusted according to the specifications of the four-roll plate rolling machine. 2. The two racks moving towards each other can cause the two limiting plates to move towards each other, and the two main shafts rotating in opposite directions at the same time can cause the two limiting plates to move away from each other. The distance between the two limiting plates can be adjusted according to the width of the sheet material to be rolled. 3. The support rollers facilitate the workers to push the sheet material to be rolled into the four-roll plate rolling machine body for feeding. 4. The four-roll plate bending machine body can bend and shape the plate. By setting two limit plates, it ensures that the plate to be rolled is always fed in a straight line, preventing the plate from deviating and improving product quality. Attached Figure Description

A spur gear 13 is fixedly provided on the upper end of the rotating shaft 15. The spur gear 13 meshes with the rack 5. The rotation of the two spur gears 13 can cause the two racks 5 to move towards each other. The rotation of the spur gears 13 in the opposite direction can cause the two racks 5 to move away from each other.

[0016] A driven bevel gear 16 is fixedly provided at the lower end of the rotating shaft 15. The rotation of the two driven bevel gears 16 can cause the two spur gears 13 to rotate.

[0017] The side plate 3 is rotatably provided with a main shaft 18, and the outer end of the main shaft 18 is fixedly provided with a drive bevel gear 17. The two drive bevel gears 17 are symmetrical to each other. The drive bevel gears 17 mesh with the driven bevel gears 16. The rotation of the two main shafts 18 can cause the two drive bevel gears 17 to rotate, and the rotation of the two drive bevel gears 17 can cause the two driven bevel gears 16 to rotate.

[0018] A dual-output shaft servo motor 20 is fixedly installed on the top surface of the lifting plate 10. The two output shafts of the dual-output shaft servo motor 20 are respectively fixedly connected to one end of the two main shafts 18. The dual-output shaft servo motor 20 can make the two main shafts 18 rotate simultaneously.

[0019] A servo cylinder 7 is fixedly installed on the top surface of the base 2. The extension end of the servo cylinder 7 is fixedly connected to the bottom surface of the lifting plate 10. The extension and retraction of the servo cylinder 7 can make the lifting plate 10 rise and fall.

[0020] Multiple guide rods 6 have connecting rods 4 fixedly attached to their outer ends. The connecting rods 4 are fixedly connected to the outer ends of the rack 5. The connecting rods 4 are used to reinforce the guide rods 6 and the rack 5.
