Description

Technical Field

[0001] The invention relates to the technical field of disassembling a retaining spring of a support roller of a rolling mill, and in particular to the field of retaining spring disassembling equipment. Background Art

[0002] In steel production, the support rolls of rolling mills are inevitably prone to defects and damage, requiring regular maintenance, disassembly, and inspection to ensure the rolls maintain their performance. Removing the retaining spring is essential when disassembling the support roll components. Traditional methods for removing retaining springs rely primarily on manual disassembly, which can have significant variations in effectiveness.

[0003] In recent years, there have been technological developments in the removal of circlips. For example, existing technologies include circlip pliers and circlip removal equipment for removing circlips. For example, CN201911404925.1 describes a circlip pliers in which both jaws move horizontally during the process of opening the circlip. The relative position of the jaws and the circlip does not change, and the force-bearing area and direction of the circlip do not change, allowing the circlip to be stably opened.

[0004] For example, the CN202420485695.6 retaining spring removal device drives the retaining spring fork downward toward the retaining spring through a lifting mechanism, so that the two abutting protrusions on the removal part are located between the openings of the retaining spring, and continues to apply downward force to stretch the front end of the removal part. Under the action of the two abutting protrusions, the retaining spring is stretched and falls off the shaft.

[0005] How can circlips of varying sizes be automatically removed? Traditional circlip pliers require constant manual adjustment, which creates long hours of labor and safety hazards. Circlip removal devices, on the other hand, present difficulties in batch removal of circlips of varying diameters and locations.

[0006] Therefore, traditional disassembly methods cannot adapt to the automated production needs and fast pace requirements of smart factories. Summary of the Invention

The controller receives a control signal from the PLC, thereby controlling the above-mentioned execution device.

[0017] As a further solution of the present invention: the disassembly principle and method include the following steps:

[0018] S0. The disassembly assembly is preset at the large diameter adaptation station. If the support roller to be disassembled is of large diameter specification, the current station configuration is maintained; if it is of small diameter specification, the third drive control unit controls the third motor, thereby driving the adaptive diameter-changing mechanism to complete a 180° precise flip around the flip axis, so that the disassembly assembly switches to the small diameter adaptation station and stops; wherein, the disassembly head 1 corresponds to the large diameter adaptation station, and the disassembly head 2 corresponds to the small diameter adaptation station;

[0019] S1. The support roller to be disassembled is conveyed to the V-block for fixed positioning. The initial position of the disassembly assembly is preset according to the diameter of the circlip to be disassembled. After the preset is completed, the first drive control unit controls the first motor to rotate forward, thereby driving the entire circlip disassembly device to begin to advance along the slide rail. During operation, the data processor receives pressure signals fed back by the pressure sensor in real time, wherein the pressure sensor continuously monitors the contact pressure parameters.

[0020] S2. When the data processing unit receives the pressure signal, that is, the disassembly assembly reaches the end face of the retaining spring, the first drive control unit controls the first motor to stop, and the entire disassembly device stops moving forward; if one pair of the pressure signals is zero, it means that two disassembly heads just fall into the holes of the retaining spring to be disassembled; if both pressure signals are not zero, the second drive control unit controls the second motor to rotate forward, thereby driving the disassembly assembly to perform circumferential rotation; when one pair of pressure signals is zero, it means that two disassembly heads are ejected by the spring and have successfully embedded in the positioning holes of the retaining spring to be disassembled, completing the mechanical interlocking, and the second drive control unit controls the second motor to stop, and the disassembly assembly maintains its current position;

[0021] S3, the fourth drive control unit starts the fourth motor to drive the disassembly assembly to perform radial contraction movement, so that the disassembly assembly clamps the retaining spring to be disassembled and releases it from the support roller constraint. At this time, the fourth drive control unit controls the fourth motor to stop, and the disassembly assembly maintains its current position. At the same time, the first drive control unit controls the first motor to reverse, thereby driving the entire retaining spring disassembly device to move backward along the slide rail, so that the retaining spring to be disassembled is released from the support roller area to above the retaining spring collection frame. At this time, the first drive control unit controls the first motor to stop.

[0022] S4. The third drive control unit starts the third motor, and then drives the adaptive diameter-changing mechanism to rotate around the flip axis. When it rotates to 90°, the third drive control unit controls the third motor to stop, and at the same time the fourth drive control unit controls the fourth motor to reverse, and then drives the disassembly component to perform radial expansion movement, so that the disassembly component loosens the retaining spring to be disassembled and falls into the retaining spring collection frame; at this point, the device completes the retaining spring disassembly.

[0023] Beneficial effects:

[0024] (1) The disassembly assembly of the present invention generates radial displacement through gear transmission, so that the disassembly assembly as a whole generates continuous and uniform displacement movement on the surface of the retaining spring, which can ensure the centering of the device during the removal of the retaining spring, and the device can remove retaining springs of different diameters and has good adaptability.

[0025] (2) The present invention's flip mechanism achieves a 180-degree flip function for the adaptive diameter-changing mechanism and disassembly assembly through gear transmission. This design not only enables the disassembly assembly to adapt to the removal requirements of retaining rings with a wide range of diameters, significantly improving the versatility of the device, but also, thanks to the use of the gear transmission system, makes the entire device compact and operates smoothly and reliably.

[0026] (3) The fine-tuning mechanism of the present invention realizes a certain rotation of the adaptive diameter-changing mechanism and the disassembly assembly in the circumferential direction through gear transmission, and the disassembly assembly is composed of four disassembly units, so that it can be positioned to the position of the retaining spring hole without rotating more than 90° in the circumferential direction. The mechanism has good adaptability to different positions of the retaining spring in the support roller and has an efficient positioning effect. BRIEF DESCRIPTION OF THE DRAWINGS

The initial position of the disassembly assembly 6 is preset according to the diameter of the retaining spring to be disassembled. After the preset is completed, the first drive control unit controls the first motor 36 to rotate forward, thereby driving the entire retaining spring disassembly device to start moving forward along the slide rail 33. During the operation, the data processor 71 receives the pressure signal fed back by the pressure sensor 68 in real time, wherein the pressure sensor 71 continuously monitors the contact pressure parameter. Figure 14 (b)

[0070] S2. When the data processing unit 71 receives the pressure signal, that is, the disassembly component 6 reaches the end face of the retaining spring, the first drive control unit controls the first motor 36 to stop, and the entire disassembly device stops moving forward; if one pair of the pressure signals is zero, it means that two disassembly heads 63 just fall into the holes of the retaining spring to be disassembled; if the pressure signals are not zero, the second drive control unit controls the second motor 39 to rotate forward, thereby driving the disassembly component 6 to perform circumferential rotation; when one pair of pressure signals is zero, it means that two disassembly heads 63 are ejected by the spring 61 and have been successfully embedded in the positioning holes of the retaining spring to be disassembled, completing the mechanical interlocking. At this time, the second drive control unit controls the second motor 39 to stop, and the disassembly component 6 maintains the current position; refer to Figure 14 (c)

[0071] S3, the fourth drive control unit starts the fourth motor 56, drives the disassembly assembly 6 to perform radial contraction movement, so that the disassembly assembly 6 clamps the retaining spring to be disassembled and breaks away from the support roller constraint, at this time the fourth drive control unit controls the fourth motor 56 to stop, and the disassembly assembly 6 maintains the current position; at the same time, the first drive control unit controls the first motor 36 to reverse, thereby driving the entire retaining spring disassembly device to move backward along the slide rail 33, so that the retaining spring to be disassembled breaks away from the support roller area to above the retaining spring collection frame 8, at this time the first drive control unit controls the first motor 36 to stop; refer to Figure 14(d) in

[0072] S4. The third drive control unit starts the third motor 43, which in turn drives the adaptive diameter-changing mechanism 5 to rotate around the flip axis 47. When the rotation reaches 90°, the third drive control unit controls the third motor 43 to stop, and the fourth drive control unit controls the fourth motor 56 to reverse, thereby driving the disassembly assembly 6 to perform radial expansion movement, causing the disassembly assembly 6 to release the retaining spring to be disassembled and drop it into the retaining spring collection frame 8. At this point, the device completes the retaining spring removal. Figure 14 (e) and (f) in the
