Description

Technical Field

[0001] This utility model relates to the field of feeding machine technology, specifically to a hydraulic feeding machine for steel coils. Background Technology

[0002] Hydraulic coil feeders are mechanical equipment used in the metal processing industry to smoothly and accurately unfold and transport steel coils to subsequent processing equipment. They typically use a hydraulic system to provide power to ensure stability and accuracy during the feeding process.

[0003] For example, a stainless steel coil transfer device with application number CN201820261204.4 includes a base plate, a lifting plate, a top plate, and a connecting plate. A lifting mechanism is provided between the lifting plate and the base plate. This utility model fixes the coil by placing the inner ring of the coil on a positioning post, and using a first hydraulic cylinder to control a second hydraulic cylinder to move the support plate outward. Then, the connecting plate moves downward, and the support block provides support for the coil. The positioning post and the support block provide a reliable fixing effect for the coil. At the same time, the support block shares the weight of the coil on the positioning post, improving its service life. The lifting mechanism makes the positioning post coincide with the axis of the uncoiler's spool. By moving the support plate inward, the coil is separated from the positioning post. The coil and the support block slide forward, so that the coil is placed on the spool, making it easy to load the coil onto the uncoiler. The positioning is accurate and convenient. This utility model has a simple structure, is easy to use, and is highly practical.

[0004] Because steel coils of different sizes have different inner curvatures and the outer curvature of the support plate cannot be adjusted, the outer surface of the support plate cannot fully fit the inner surface of the steel coil. This results in uneven tension distribution between the steel coil and the support plate, which affects the quality of the steel coil and reduces the feeding effect of the hydraulic feeder. Therefore, it is urgent to design a hydraulic feeder for steel coils to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a hydraulic feeder for steel coils to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] It includes a support plate and a square plate, wherein a clamping assembly is provided on the front side of the support plate, and a feeding assembly is provided on the front side of the support plate;

[0008] The feeding assembly includes a feeding frame fixedly installed on one side of the square plate. A groove is provided on one side of the feeding frame, and a fitting structure is provided in the groove. The fitting structure is at least used to fit against the inner surface of the steel coil.

[0009] A limiting structure, which is at least used for self-locking of the bonding structure.

[0010] The feeding assembly enables the bonding plate to adhere to the inner surface of the steel coil while simultaneously locking it in place. This prevents the bonding plate from failing to adhere completely to the inner surface of the steel coil, which could lead to uneven tension distribution between the steel coil and the bonding plate and affect the quality of the steel coil. As a result, the feeding effect of the hydraulic feeder on the steel coil is improved.

[0011] The bonding structure includes a bonding plate, a spring, and a first anti-slip plate. The bonding plate is slidably installed in the groove, the spring is fixedly installed between the bonding plate and the feeding frame, and the first anti-slip plate is fixedly installed on one side of the bonding plate.

[0012] The limiting structure includes an L-shaped plate, a gear, a first rack, a moving block, a second rack, a clamping plate, and a second anti-slip plate. The L-shaped plate is fixedly installed inside the feeding frame. The gear is rotatably installed on one side of the L-shaped plate. A groove is provided on one side of the bonding plate. The first rack is fixedly installed on one side of the bonding plate. The moving block is slidably installed on one side of the L-shaped plate. The second rack is fixedly installed on one side of the moving block. The clamping plate is slidably installed inside the feeding frame and is fixedly connected to the moving block. The second anti-slip plate is fixedly installed on one side of the clamping plate.

[0013] A base is fixedly installed at the bottom of the support plate, a support device is provided at the top of the base, a flattening device is provided at the top of the base, and a motor is fixedly installed at the rear side of the support plate.

[0014] The clamping assembly includes a rotating plate, a clamping frame, a hydraulic cylinder, a connecting plate, and a rotating shaft. The rotating plate is rotatably mounted on the front side of the support plate and is connected to the output end of the motor.

[0015] The clamping frame is fixedly installed on the front side of the rotating plate, the hydraulic cylinder is fixedly installed inside the clamping frame, and square slots are provided on all four sides of the clamping frame. The square plate is slidably installed in the square slots, the connecting plate is rotatably installed on the square plate and the output end of the hydraulic cylinder, and the rotating shaft is rotatably installed on the front side of the clamping frame.

[0016] In the above technical solution, the hydraulic feeder for steel coils provided by this utility model has the following advantages:

[0017] The feeding assembly enables the bonding plate to adhere to the inner surface of the steel coil while simultaneously locking it in place. This prevents the bonding plate from failing to adhere completely to the inner surface of the steel coil, which could lead to uneven tension distribution between the steel coil and the bonding plate and affect the quality of the steel coil. As a result, the feeding effect of the hydraulic feeder on the steel coil is improved.

[0018] The second anti-slip plate increases the friction between the plate and the bonding plate, thereby improving the stability of the hydraulic feeder during use.

[0019] The clamping assembly can adjust the position of the feeding frame according to steel coils of different sizes, thereby improving the flexibility of the hydraulic feeder during use. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown in the figure, this utility model provides a hydraulic feeder for steel coils.

[0028] It includes a support plate 1 and a square plate 2. A clamping assembly 3 is provided on the front side of the support plate 1, and a feeding assembly 4 is provided on the front side of the support plate 1.

[0029] The feeding assembly 4 includes a feeding frame 5 fixedly installed on one side of the square plate 2. A groove 6 is provided on one side of the feeding frame 5. A fitting structure 28 is provided in the groove 6. The fitting structure 28 is at least used to fit against the inner surface of the steel coil.

[0030] The limiting structure 29 is used to self-lock the bonding structure 28. The square plate 2 drives the feeding frame 5 to move, which in turn drives the bonding plate 7 to move. The bonding plate 7 is then bonded to the inner surface of the steel coil via the first anti-slip plate 15. The bonding plate 7 compresses the spring 8. The bonding plate 7 drives the clamping plate 16 to move via the first rack 12, the gear 10, and the second rack 14. The clamping plate 16 is then bonded to the bonding plate 7 via the second anti-slip plate 17, which compresses and limits the bonding plate 7. After the inner surface of the steel coil is fully bonded to the bonding plate 7, the hydraulic cylinder 24 is closed, and the support device 19 is controlled to support the clamping frame 23 via the rotating shaft 26. The flattening device 20 is controlled to flatten the steel coil. The motor 21 is started to drive the steel coil to rotate and feed via the rotating plate 22, the clamping frame 23, the square plate 2, the feeding frame 5, and the bonding plate 7.

[0031] The feeding assembly 4 can make the bonding plate 7 adhere to the inner surface of the steel coil while locking it, thereby preventing the bonding plate 7 from failing to adhere completely to the inner surface of the steel coil, which would lead to uneven tension distribution between the steel coil and the bonding plate 7 and affect the quality of the steel coil. This increases the feeding effect of the hydraulic feeder on the steel coil.

[0032] Reference Figure 3 The bonding structure 28 in this embodiment includes a bonding plate 7, a spring 8 and a first anti-slip plate 15. The bonding plate 7 is slidably installed in the slide groove 6, the spring 8 is fixedly installed between the bonding plate 7 and the feeding frame 5, and the first anti-slip plate 15 is fixedly installed on one side of the bonding plate 7.

The clamping plate 16 is fixedly connected to the moving block 13. The second anti-slip plate 17 is fixedly installed on one side of the clamping plate 16.

[0034] The second anti-slip plate 17 can increase the friction between the clamping plate 16 and the bonding plate 7, thereby improving the stability of the hydraulic feeder during use.

[0035] A base 18 is fixedly installed at the bottom of the support plate 1, a support device 19 is provided at the top of the base 18, a flattening device 20 is provided at the top of the base 18, and a motor 21 is fixedly installed at the rear side of the support plate 1.

[0036] Reference Figure 2 The clamping assembly 3 in this embodiment includes a rotating plate 22, a clamping frame 23, a hydraulic cylinder 24, a connecting plate 25, and a rotating shaft 26. The rotating plate 22 is rotatably mounted on the front side of the support plate 1 and is connected to the output end of the motor 21.

[0037] The clamping assembly 3 can adjust the position of the feeding frame 5 according to steel coils of different sizes, thereby improving the flexibility of the hydraulic feeder during use.

[0038] The clamping frame 23 is fixedly installed on the front side of the rotating plate 22, the hydraulic cylinder 24 is fixedly installed inside the clamping frame 23, and square slots 27 are provided on all four sides of the clamping frame 23. The square plate 2 is slidably installed in the square slots 27, the connecting plate 25 is rotatably installed on the square plate 2 and the output end of the hydraulic cylinder 24, and the rotating shaft 26 is rotatably installed on the front side of the clamping frame 23.

[0039] Working principle: First, the steel coil is placed on the bonding plate 7. The hydraulic cylinder 24 is started, which drives the square plate 2 to move through the connecting plate 25. The square plate 2 drives the feeding frame 5 to move, which in turn drives the bonding plate 7 to move. The bonding plate 7 is then pressed against the inner surface of the steel coil through the first anti-slip plate 15. The bonding plate 7 compresses the spring 8. The bonding plate 7 drives the clamping plate 16 to move through the first rack 12, the gear 10, and the second rack 14. The clamping plate 16 is then pressed against the bonding plate 7 through the second anti-slip plate 17, which compresses and limits the bonding plate 7. After the inner surface of the steel coil is completely pressed against the bonding plate 7, the hydraulic cylinder 24 is closed. The support device 19 is controlled to support the clamping frame 23 through the rotating shaft 26. The flattening device 20 is controlled to flatten the steel coil. The motor 21 is started, which drives the steel coil to rotate and feed through the rotating plate 22, the clamping frame 23, the square plate 2, the feeding frame 5, and the bonding plate 7.
