Description

Technical Field

[0001] This invention relates to the field of metal polishing technology, and more particularly to an adaptive polishing device. Background Technology

[0002] In the field of continuous hot steel billet processing in the metallurgical industry, online grinding of surface oxide scale and defects is a crucial finishing process, which directly affects the surface quality and performance of the final rolled product. For this reason, fixed grinding equipment is usually set up on the production line, which aims to clean the billet surface by contacting it with its rotating grinding tools during the billet conveying process.

[0003] The core working principle of this type of conventional grinding device is that its grinding mechanism is usually rigidly installed on one or both sides of the production line roller conveyor. When the steel billet passes along the predetermined path, the grinding tool makes forced mechanical contact with the surface of the steel billet in a fixed posture and pressure, and completes the grinding operation by relying on friction.

[0004] However, the surface of steel billets often has unevenness and warping. The fixed grinding gap in existing grinding devices cannot make the grinding tool fit closely to the complex curved surface of the steel billet, which can easily lead to uneven grinding, missed grinding, or excessive wear.

[0027] Please see Figures 1-4 This invention provides an adaptive grinding device, comprising: a housing 10 including a feed channel 11 for conveying a workpiece 50 to be ground; a first grinding mechanism 20 movably disposed on one side of the feed channel 11; a second grinding mechanism 30 movably disposed on the other side of the feed channel 11, wherein the first grinding mechanism 20 and the second grinding mechanism 30 form a grinding gap for the workpiece 50 to pass through; and an elastic mechanism 40 elastically connected to the first grinding mechanism 20 and / or the second grinding mechanism 30; wherein the elastic mechanism 40 provides an elastic force for the first grinding mechanism 20 and / or the second grinding mechanism 30 to move in opposite directions, so that the first grinding mechanism 20 and the second grinding mechanism 30 respectively abut against both sides of the workpiece 50.

[0028] It is understandable that on a continuous production line, metal workpieces 50 (such as hot steel billets) inevitably undergo morphological changes such as bending, warping, or uneven surfaces during the conveying process. Traditional grinding devices, due to their fixed installation gaps and pressures, cannot effectively adapt to these changes, resulting in the grinding tools failing to fit tightly against the surface of the workpiece 50, especially uneven curved surfaces, causing uneven grinding, missed grinding, or over-grinding. Based on this, in this embodiment, the first grinding mechanism 20 and / or the second grinding mechanism 30 are connected by an elastic mechanism 40, and a force is always applied to bring the first grinding mechanism 20 and the second grinding mechanism 30 closer to each other. When the irregularly shaped workpiece 50 enters the grinding gap, the workpiece 50 will generate a reaction force on the grinding mechanism to overcome the elastic force, forcing the two grinding mechanisms to move in opposite directions, thereby passively expanding the grinding gap to accommodate the workpiece 50. Correspondingly, the elastic force provided by the elastic mechanism 40 continuously drives the first grinding mechanism 20 and the second grinding mechanism 30 to press against the surface of the workpiece 50, so that the grinding pressure can adapt to the changes in the contour of the workpiece 50. Through dynamic adaptive pressing, uniform contact between the grinding tool and the surface of the irregular workpiece 50 is ensured, eliminating missed grinding and improving the uniformity and consistency of the grinding effect.

[0029] In some embodiments, the first grinding mechanism 20 includes a first grinding roller 21 and a first driving member 22, the first driving member 22 being driven to the first grinding roller 21 for driving the first grinding roller 21 to rotate; wherein the first grinding roller 21 forms a first sidewall of the grinding gap. Optionally, the second grinding mechanism 30 includes a second grinding roller 31 and a second driving member 32, the second driving member 32 being driven to the second grinding roller 31 for driving the second grinding roller 31 to rotate; wherein the second grinding roller 31 forms a second sidewall of the grinding gap.

[0030] It is understandable that the rotational power output by the first driving component 22 drives the first grinding roller 21 to rotate around its own axis through the transmission connection. When the first grinding roller 21 comes into contact with the surface of the metal part passing through the grinding gap, the grinding process on the surface of the workpiece 50 is achieved through friction.

[0031] Furthermore, the surface of the first grinding roller 21 is covered with a layer of steel wire. Optionally, the surface of the second grinding roller 31 is covered with a layer of steel wire.

[0032] It should be explained that traditional grinding devices typically use abrasive wheels, which are difficult to adapt to the characteristics of hot steel billets. The high temperature on the surface of hot steel billets often causes the abrasive wheel binder to fail, resulting in frequent slag shedding. These residues easily adhere to the surface of the steel billet, severely reducing its quality. Therefore, this embodiment uses a specific steel wire layer to cover the surfaces of the first grinding roller 21 and the second grinding roller 31. Utilizing the high heat resistance of the steel wire layer itself, it maintains its structural integrity and grinding ability even under the high-temperature radiation of the hot steel billet, unlike abrasive wheels which experience performance degradation or contamination.

[0033] In some embodiments, the first grinding mechanism 20 further includes a first mounting bracket 23, which is rotatably disposed on the housing 10. The first grinding roller 21 is rotatably mounted on the first mounting bracket 23. An elastic mechanism 40 is elastically connected to the first mounting bracket 23 to provide the first mounting bracket 23 with an elastic force that causes the first grinding roller 21 to rotate toward the second grinding mechanism 30. Optionally, the second grinding mechanism 30 further includes a second mounting bracket 33, which is rotatably disposed on the housing 10. The second grinding roller 31 is rotatably mounted on the second mounting bracket 33. The elastic mechanism 40 is elastically connected to the second mounting bracket 33 to provide the second mounting bracket 33 with an elastic force that causes the second grinding roller 31 to rotate toward the first grinding mechanism 20.

[0034] It is understood that in this embodiment, the first mounting bracket 23 is rotatably mounted on the outer casing 10 via a structure such as a rotating shaft or bearing seat, providing the first grinding mechanism 20 with a precise, single-degree-of-freedom motion around a fixed axis, the trajectory of which is an arc. The elastic mechanism 40 is elastically connected to the first mounting bracket 23, generating a torque relative to the rotation center of the first mounting bracket 23. When the first mounting bracket 23 rotates, it drives the first grinding roller 21 closer to or further away from the second grinding roller 31, thereby reducing or increasing the grinding gap. Specifically, before the metal workpiece 50 passes through the grinding gap, the first mounting bracket 23 is held in its initial position, where the first grinding roller 21 is closest to the second grinding mechanism 30, under the elastic torque provided by the elastic mechanism 40. When the workpiece 50 enters the grinding gap and exerts a thrust on the first grinding roller 21, this thrust acts on the first mounting bracket 23, generating a torque relative to the rotation center of the first mounting bracket 23 that is opposite in direction to the elastic torque provided by the elastic mechanism 40. Subsequently, the first mounting bracket 23 rotates to drive the first grinding roller 21 closer to the second grinding mechanism 31. 1. Lift along the arc to allow the metal workpiece 50 to smoothly enter the grinding gap; as the metal workpiece 50 continues to enter, under the dynamic balance of the thrust generated by the metal workpiece 50 on the first grinding roller 21 and the elastic force generated by the elastic mechanism 40 on the first mounting bracket 23, the first mounting bracket 23 will stop at a corresponding corner position. At this time, the first grinding roller 21 presses the surface of the workpiece 50 with appropriate pressure and performs rotational grinding. If the surface of the workpiece 50 is not flat, the balance position will be adjusted in real time so that the first grinding roller 21 is always pressed against the surface of the workpiece 50.

[0035] In some embodiments, the first mounting bracket 23 has a first end and a second end located on both sides of its rotation center, and the first grinding roller 21 is mounted on the first end; the elastic mechanism 40 is elastically connected to the first end and / or the second end.

[0036] It should be explained that, in this embodiment, the first mounting bracket 23 is equivalent to a double-arm lever, where the first end is one lever arm and the second end is the other lever arm. In this embodiment, the elastic mechanism 40 can achieve elastic drive of the first grinding roller 21 whether it is connected to the first end or the second end.

[0037] Furthermore, the elastic mechanism 40 includes a fixed base 41 disposed on the housing 10, and a first elastic element 42 connected to the fixed base 41 and the first grinding mechanism 20, and / or a second elastic element 43 connected to the fixed base 41 and the second grinding mechanism 30; the first mounting bracket 23 is rotatably connected to the fixed base 41, and the second mounting bracket 33 is rotatably connected to the fixed base 41.

[0038] Understandably, the fixed base 41 is securely mounted on the housing 10, and the first mounting bracket 23 is rotatably connected to the fixed base 41. Simultaneously, the first elastic element 42 is also connected between the fixed base 41 and the first grinding mechanism 20. When the workpiece 50 pushes the first grinding roller 21, causing the first mounting bracket 23 to rotate, since the deformation of the first elastic element 42 occurs relative to the fixed base 41, and the fixed base 41 remains stationary, the change in elastic force can be accurately and without lag converted into a torque on the first mounting bracket 23, driving it to respond.

[0039] Optionally, a single first elastic element 42 is provided, with one end connected to the first end and the other end connected to the fixed base 41, for providing an elastic force to pull the first end closer to the second grinding mechanism 30. In this embodiment, a single first elastic element 42 is directly connected to the fixed base 41 and the first end of the first mounting bracket 23, directly applying a pulling force to the first end pointing towards the fixed base 41. This pulling force generates a torque that causes the first mounting bracket 23 to rotate about the rotation center, with the direction being to bring the first grinding roller 21 toward the workpiece 50.

[0040] Optionally, a single first elastic element 42 is provided, with one end connected to the second end and the other end connected to the fixed base 41. This first elastic element 42 provides an elastic force to push the second end away from the second grinding mechanism 30, causing the first mounting bracket 23 to rotate towards the first end and closer to the second grinding mechanism 30. In this embodiment, a single first elastic element 42 is connected to the fixed base 41 and the second end of the first mounting bracket 23. By applying a thrust to the second end, i.e., pushing the second end away from the workpiece 50, the first end rotates towards the workpiece 50.

[0041] Optionally, two first elastic elements 42 are provided. One end of the first elastic element 42 is connected to the first end and the other end is connected to the fixed base 41; one end of the second first elastic element 42 is connected to the second end and the other end is connected to the fixed base 41. In this embodiment, first elastic elements 42 connected to the fixed base 41 are respectively provided at the first end and the second end. A first spring connected between the first end and the fixed base 41 provides a pulling force from the first end toward the metal workpiece 50, and a first spring connected between the second end and the fixed base 41 provides a pushing force from the second end away from the metal workpiece 50.

[0042] In some embodiments, the housing 10 further includes a limiting block 13. When the distance between the first grinding mechanism 20 and the material channel 11 is less than a preset threshold, the limiting block 13 abuts against the first grinding mechanism 20. When the first grinding mechanism 20 moves towards the material channel 11 under the action of elastic force, and the distance between them decreases to the preset threshold, the first grinding mechanism 20 will contact the limiting block 13 disposed on the housing 10, preventing the first grinding mechanism 20 from continuing to move towards the material channel 11.

[0043] It should be explained that when no workpiece 50 passes through the grinding gap, if only the pulling or pushing force of the elastic mechanism 40 is relied upon, the first grinding mechanism 20 may move excessively towards the material channel 11, causing it to interfere or collide with the material channel 11, or making the grinding gap too small, affecting the smooth introduction of the next workpiece 50. The limiting block 13 in this embodiment eliminates this risk by physically stopping the workpiece.

[0044] In some embodiments, the housing 10 further includes a protective box 12, through which the material channel 11 passes and the grinding gap is located in the protective box 12.

[0045] Understandably, the protective box 12 physically creates a closed or semi-closed space that is relatively isolated from the external environment, confining potential hazards such as high-speed flying shavings, sparks, and broken steel wires generated during the grinding process within a limited and controlled space, preventing them from spreading outward, thereby protecting the safety of external personnel, equipment, and the environment.

[0046] The above examples are merely illustrative of the technical content of the present invention to facilitate easier understanding by the reader, but do not imply that the implementation of the present invention is limited to these examples. Any technical extensions or re-creations made based on the present invention are protected by the present invention. The scope of protection of the present invention is defined by the claims.
