Description

Technical Field

[0001] The present invention belongs to the technical field of instruments, and in particular relates to an adaptive coating cutting device and a coating cutting method. Background Art

[0002] In industrial production, coating protection is a key means of slowing down metal corrosion. The effectiveness of a coating's protection is directly dependent on its adhesion to the substrate. Pull-off testing, the mainstream method for on-site adhesion testing, involves mechanically creating a circular isolation zone through the coating after curing. The peel strength is then measured using a spindle. According to standards such as "GB / T 5210-2006 Paints and varnishes - Adhesion test by pull-off method," the groove depth must be precise, extending from the coating to the substrate surface while avoiding structural damage to the metal substrate to ensure accurate test data.

[0003] The current industry generally uses alloy steel cutter heads for grooving operations, which use high-speed rotating blades to cut into the coating vertically. This technology performs stably in applications such as flat substrates such as steel plates and storage tanks, with a regular cutting surface and low substrate damage rate. However, in scenarios with curved substrates such as oil and gas pipelines and ship crankshafts, traditional rigid cutter heads have exposed significant defects: the contact area between the cutter head plane and the curved coating is less than 30% (when the curvature radius is less than 150mm), resulting in stress concentration at the cutting edge during cutting, causing two types of failures: (1) Over-cutting: the cutter head continues to cut the metal substrate after partially penetrating the coating, causing microcracks or even stress corrosion sources; (2) Groove discontinuity: uneven surface fit forms intermittent grooves, causing the coating peeling interface to shift during the pull-out test. In essence, the difficulty of curved surface grooving lies in the coordinated control of dynamic curvature adaptation and constant pressure cutting. To ensure a good cutting effect, the cutter head needs to be designed so that it can actively sense the surface curvature and adjust the contact posture in real time, while maintaining a constant cutting pressure. Summary of the Invention

[0004] In view of the shortcomings of the prior art mentioned above, the purpose of the present invention is to provide an adaptive coating cutting device and a coating cutting method, which can achieve adaptive fitting of the working surface of the cutter head and the small curvature substrate, and alarm when cutting to the metal layer, thereby solving the problems of accuracy of curved coating grooving and substrate protection to a certain extent.

[0048] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0049] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0050] Coating adhesion is a key indicator for evaluating the bonding strength between the coating and the substrate, and is directly related to the durability and reliability of the coating product. The pull-off test is a standardized method for quantitatively evaluating the interfacial bonding strength between the coating and the substrate through mechanical peeling. It mainly forms an annular isolation area through mechanical grooving, and then measures the peeling strength by spindle adhesion. In the actual operation process, key links such as grooving, bonding, pulling and result analysis must be strictly controlled. At present, alloy steel cutter heads are generally used for grooving operations. The high-speed rotating blade cuts into the coating vertically. During the cutting process of the curved substrate, intermittent grooves will be formed due to uneven fit between the cutter head and the curved surface, causing the coating peeling interface to shift in the pull-off test, and the cutting depth of the cutter head cannot be controlled. After penetrating the coating, the cutter head will continue to cut the metal substrate, causing microcracks and even stress corrosion sources.

[0051] See also Figures 1 to 9 The present invention proposes an adaptive coating cutting device, comprising a cutting module and an alarm module. The cutting module is used to cut the coating of the substrate. During the curved surface cutting process, the cutting module can adapt to the curvature of the curved surface to form uniform and stable grooves. The alarm module is electrically connected to the cutting module. When the coating is cut, the cutting module enters the metal layer and contacts the metal surface, thereby activating the alarm module to automatically sound an alarm, thereby stopping cutting and avoiding excessive cutting into the metal layer. The cutting device of the present invention can ensure the continuity of the groove body when grooving a flat or curved surface, avoiding intermittent empty grooves. It can also realize automatic alarm when cutting into the metal layer, preventing excessive cutting and ensuring cutting quality, and can meet the requirements of curved surface coating adhesion testing.

[0052] See also Figures 1 to 8 In an optional embodiment of the present invention, the cutting module includes a tool holder 100, a tool head 200 and a positioning assembly 300. The tool holder 100 is used to connect the cutter head 200 and the positioning assembly 300, and is connected to a power source, such as an impact drill, which can provide power to drive the cutter head 200 to rotate at high speed for cutting operations; multiple groups of cutter heads 200 are arranged along the circumference of the tool holder 100, and the cutter heads 200 and the tool holder 100 are connected by elastic parts, and the elastic parts are used to cooperate to achieve the movement of the cutter head 200 relative to the tool holder 100 in the axial direction, so that when performing curved surface cutting, the position of the cutter head 200 can be adjusted to achieve adaptive fit with the surface of the substrate, and the coating is cut continuously and evenly; the positioning assembly 300 is arranged in the tool holder 100, and is used to center the tool holder 100 and the cutter head 200. During the cutting operation, the positioning assembly 300 is pressed on the spindle, and the cutter head 200 makes a circular cut on the outer edge of the spindle. During the cutting process, the positioning assembly 300 is always pressed above the spindle and remains fixed to ensure that the cutting trajectory of the cutter head 200 is uniform and stable.

[0053] See also Figures 1 to 5In an optional embodiment of the present invention, the knife seat 100 includes a knife root 110, a blade stopper 120 and a stiffening blade 130. The knife root 110 is used to connect to a power source to drive the rotation of the cutting module. The blade stopper 120 is provided at one end of the knife root 110 and is connected to the knife root 110. A plurality of groups of cutter heads 200 are arranged along the circumference of the knife seat 100 and are connected to the knife seat 100 through elastic members. With the cooperation of the elastic members, they can move along the axial direction of the knife seat 100, thereby adjusting the position of the cutter heads 200. The stiffening blade 130 is fixed on the blade stopper 120. The plurality of groups of cutter heads 200 and the stiffening blade 130 are evenly arranged along the circumference of the blade stopper 120. The rear end of the cutter head 200 is connected to the blade stopper 120 through an elastic member, and the front end of the cutter head 200 contacts the substrate for cutting. By splitting the annular cutter head 200 and utilizing the linkage between the blade limiter 120 and the elastic member to realize the axial movement of the cutter head 200, it can adapt to the cutting of curved surfaces. At the same time, the stiffening blade 130 is used to ensure the strength and stability of the cutter head 200 structure.

[0054] See also Figures 1 to 7 In an optional embodiment of the present invention, the cutter heads 200 are evenly arranged along the circumference of the blade limiter 120, and multiple groups of cutter heads 200 are evenly arranged along the circumference of the blade limiter 120, and are connected to the blade limiter 120 through elastic parts, so that they can move axially along the blade limiter 120. The cutter head 200 includes a cutter head housing 210, a blade fixing part 220 and a cutting blade 230. The blade fixing part 220 is movably connected to the blade limiter 120 through an elastic part. The cutting blade 230 is fixedly connected to the blade fixing part 220, and one end of the cutting blade 230 is arranged in the blade limiter 120. The cutting blade 230 and the blade fixing part 220 can move axially relative to the blade limiter 120 with the cooperation of the elastic part; the blade fixing part 220 and the blade limiter 120 are arranged in the cutter head housing 210 and are protected by the cutter head housing 210. At the same time, the cutter head housing 210 is fixed to the knife holder 100, and one end of the cutting module is limited by the fixed cutter head housing 210. The cutting end of the cutting blade 230 extends out of the cutter head housing 210 for cutting, and multiple groups of cutter heads 200 can respectively move axially along the blade limiter 120 in the cutter head housing 210 to adapt to the curvature of the cutting surface.

[0055] It can be understood that multiple groups of blade fixings 220 and cutting blades 230 are distributed in a ring shape. During the cutting process, the center of the ingot is used as the center of the circle, and the blade group is used for circular cutting. The split structure enables the cutting blades 230 at different positions to move axially independently, thereby adapting to the curved surface structure and being able to adapt to grooving tasks on various planes such as curved surfaces and flat surfaces.

[0056] See also Figures 1 to 5In an optional embodiment of the present invention, the blade limiter 120 includes a first limiter end 121 and a second limiter end 122. The first limiter end 121 is arranged at one end of the blade root 110, and the second limiter is arranged at an end away from the blade root 110. The first limiter end 121 and the second limiter end 122 are connected by a stiffening blade 130. The cutting blade 230 is limited by the two limiter ends. The blade fixing member 220 can move axially between the first limiter end 121 and the second limiter end 122 and drive the cutting blade 230 to move. Specifically, the blade limiter 120 is an annular structure, the stiffening blade 130 and the cutting blade 230 are arranged in the annular gap, the stiffening blade 130 is rigidly connected to the blade limiter 120, the blade fixing member 220 is arranged on the outside of the blade limiter 120, and the outer edge of the blade limiter 120 extends to form a connecting platform, which is connected to the blade fixing member 220 through an elastic member. The annular structure of the blade limiter 120 is used to radially limit the cutting blade 230 to ensure the stability of the cutting blade 230 under high-speed rotation. At the same time, with the cooperation of the elastic member, the cutting blade 230 can move axially relative to the blade limiter 120 and the stiffening blade 130 in the blade limiter 120 to adapt to the curved surface shape.

[0057] See also Figures 1 to 6 In an optional embodiment of the present invention, the stiffening blade 130 is fixed on the blade limiter 120, and is arranged alternately with the cutting blade 230 along the circumference of the blade limiter 120. The cutting blade 230 is rigidly connected to the blade fixing member 220. Multiple cutting blades 230 are distributed in a ring to form a blade group. A stiffening blade 130 is arranged between adjacent cutting blades 230. During the rotary cutting process, the stiffening blade 130 is used to limit the circumferential position of the annularly distributed cutting blades 230 to avoid deformation. Furthermore, a chamfer is formed at the end of the stiffening blade 130, and the reverse direction of the chamfer is opposite to the rotation direction of the cutting blade 230, which plays a stiffening role. By stiffening the blade group, the cutting blade 230 is guaranteed to be stable and reliable when cutting high-hardness materials. During the curved surface cutting process, the cutting blade 230 can move relatively along the axial direction of the blade limiter 120 with the cooperation of the elastic part. The cutting blade 230 and the stiffening blade 130 are arranged in an up and down staggered manner to maintain the blade group from falling apart. At the same time, during the movement of the cutting blade 230, the distance between the stiffening blade 130 and the base is greater than the distance between the cutting blade 230 and the base, thereby avoiding damage to the cutting surface caused by the stiffening blade 130 and ensuring the cutting quality.

[0058] See also Figures 1 to 7In an optional embodiment of the present invention, positioning holes are provided on the blade limiter 120 and the blade fixing member 220. The blade limiter 120 and the blade fixing member 220 are connected by the cooperation of the positioning member and the positioning hole. The positioning member is, for example, a fixing pin 140. Both ends of the fixing pin 140 are connected to the blade housing. The structure of the blade housing and the fixing pin 140 ensures that the internal parts of the cutter head 200 will not malfunction due to centrifugal action under high-speed operation; and the overall connection structure is simple, which is convenient for disassembly and replacement of the blade.

[0059] See also Figures 1 to 7 In an optional embodiment of the present invention, the elastic member is a spring 240, which is sleeved on the outside of the positioning member. The spring 240 and the fixing pin 140 are the inside and outside of each other, which can not only fix the cutting blade 230, but also bear the cutting resistance transmitted during the cutting process, and cooperate with the cutter head 200 to achieve adaptive adjustment of the cutting blade 230. With the cooperation of the spring 240, the blade fixing member 220 can move relative to each other in the axial direction. The spring 240 at the rear end of the cutter head 200 is used to limit the cutter head 200 to the front cutting area. The spring 240 structure is associated with the blade limiter 120. The cooperation of the two enables the cutting blade 230 to produce an adaptive effect. When the hand-held impact drill is pressed downward, the pressure is loaded to the cutter seat 100. Since the cutter seat 100 and the cutter head 200 are connected by the spring 240, the cutting blade 230 only transmits force to the spring 240 in the axial direction. The downward cutting force of the cutting blade 230 is provided by the spring 240. At the same time, when the cutting blade 230 adapts to the curved surface for axial movement, the spring 240 cooperates with it to produce adaptive deformation.

[0060] See also Figures 1 to 7 In an optional embodiment of the present invention, the side of the spring 240 connected to the blade stopper 120 is quenched. This quenching process reduces the toughness of the spring 240, making it more difficult to deform than the other side. The downward cutting force of the cutting blade 230 is provided by the spring 240. Since the side of the spring 240 near the blade root 110 is difficult to deform, the cutting force of the cutter head 200 is not changed by the size of the hand-held pressure (unless the hand-held pressure is too large and exceeds the maximum load of the elastic force at the upper end of the spring 240), reducing the impact of the hand-held pressure on the cutting effect. The special structure of the spring 240 can maintain a uniform and stable cutting force during the cutting process. At the same time, multiple groups of springs 240 are respectively connected to the blade fixing member 220 to adapt to the movement of the cutting blades 230 at different positions, so that each cutting blade 230 in the annular blade group can contact the substrate surface for cutting, ensuring the continuity and uniformity of the cutting. It can be understood that during the cutting process, since the cutting point of each cutting blade 230 on the substrate surface is constantly changing, the axial position of each cutting blade 230 and the corresponding deformation of the spring 240 are also constantly changing, and the entire cutting process is continuous and stable.

[0061] See also Figures 1 to 8 In an optional embodiment of the present invention, the positioning assembly 300 includes a bearing 310 and a central fixing member 320. The bearing 310 is installed in the knife seat 100. The knife seat 100 is provided with a bearing fixing groove, and the bearing 310 is disposed in the bearing fixing groove; the central fixing member 320 is disposed at the end of the bearing 310 away from the knife root 110. The central fixing member 320 is pressed against the surface of the spindle, and the central fixing member 320 is separated from the knife seat 100 and the cutter head 200 by the bearing 310. When the cutting module rotates, the central fixing member 320 remains fixed to the spindle under the action of the bearing 310 and does not rotate with the rotation of the cutter head 200. It can stabilize the cutter head 200 and ensure the stability of the cutting process. The central fixing member 320 can be, for example, a soft rubber pad, which can maintain good stability.

[0062] It should be noted that the position and structure of the bearing fixing groove and the central fixing member 320 need to be set according to actual cutting requirements, and central fixing members 320 of different heights can also be used to adapt to different cutting heights.

[0063] See also Figures 1 to 9 In an optional embodiment of the present invention, an alarm module is provided on the blade holder 100 to implement a metal layer cutting alarm function. The alarm module includes an alarm housing 400, an alarm 500, and an alarm circuit connecting the alarm 500 and the cutting module. The alarm housing 400 is connected and fixed to the blade root 110 via a locking ring 410 to achieve installation and fixation of the alarm module. The alarm 500 is provided within the alarm housing 400 and connected to the cutting module via the alarm circuit. The alarm 500 cooperates to generate an alarm, effectively avoiding overcutting the metal layer while completely cutting the coating, thereby ensuring cutting quality. The alarm circuit is electrically connected to at least two cutting blades 230. When the cutting blades 230 cut into the metal layer of the substrate, the alarm circuit forms a path, the alarm 500 is activated, and an alarm is sounded.

[0064] See also Figures 1 to 9In an optional embodiment of the present invention, a battery compartment 420 slot is formed inside the alarm housing 400. The battery compartment 420 is disposed within the battery compartment 420 slot for installing a battery to provide power for the alarm 500. The end of the battery compartment 420 is fixedly engaged with the alarm housing 400, facilitating battery replacement. The alarm 500 is connected to the cutting blades 230 on both sides of the tool holder via an alarm circuit. When the alarm circuit is disconnected, the alarm 500 does not operate. When the alarm circuit is connected, the alarm 500 sounds an alarm. During the cutting process, when the cutting blade 230 cuts into the metal layer of the substrate, the alarm circuit forms a path through the cutting blade 230 and the metal layer, the alarm 500 is activated and sounds an alarm. A corresponding playback port 430 is provided on the alarm housing 400. When the alarm 500 is activated, an alarm is sounded from the playback port 430. By equipping the cutter head 200 with an alarm module, an automatic alarm function can be realized when cutting into the metal layer, effectively avoiding excessive cutting of the metal layer.

[0065] See also Figures 1 to 9 In an optional embodiment of the present invention, an alarm circuit is disposed within the alarm housing, with both ends of the alarm circuit connected to the cutting blade 230 via a positive connector 510 and a negative connector 520, respectively. Specifically, the positive connector 510 and the negative connector 520 are symmetrically disposed on both sides, ensuring the reliability of the alarm during the uniform cutting process. The positive connector 510 and the negative connector 520 can, for example, be disposed within a positioning member, or a metal positioning member can be directly used as the positive connector 510 and the negative connector 520, with their lower ends extending radially inward and fixed to the cutting blade 230. The components connected to the cutting blade 230 are made of insulating material to ensure that the cutting blades 230 on both sides are insulated from each other when not cutting into the metal layer, thereby ensuring the reliability of the alarm module. When the cutting blades 230 on both sides are cutting the coating of the substrate, the alarm circuit is not connected and no alarm is sounded. When the cutting blades 230 on both sides cut into the metal layer of the substrate, the two poles of the alarm circuit form a path through the cutting blades 230 and the metal layer, and an alarm is immediately sounded. It can be understood that the entire cutting process is uniform and stable. When the coating is cut, the cutting blade 230 contacts the metal layer. Due to the high strength of the metal layer, it is more difficult for the cutting blade 230 to cut the metal layer. The alarm module can be used to quickly warn before the metal layer is cut, and the cutting can be stopped in time. A quick warning can be achieved, which effectively avoids over-cutting of the metal layer and ensures the cutting quality.

[0066] See also Figures 1 to 9 Based on the above coating cutting device, the present invention also proposes a coating cutting method, comprising the following steps:

[0067] Place the cutting device above the spindle, with the axis of the cutter head aligned with the axis of the spindle, and the center fixing piece pressed against the upper surface of the spindle;

[0068] Start the power source connected to the blade root to drive the blade head to rotate at high speed, and press the cutting device axially downward toward the substrate so that the cutting blade contacts the coating surface to perform cutting;

[0069] During the cutting process, the cutting blade actively senses the curvature of the surface under the action of the spring and adaptively moves along the axial direction, adjusting the contact posture in real time to perform continuous and uniform cutting;

[0070] When cutting to the metal layer, the alarm circuit is connected to the metal layer through the cutting blade to form a path, the alarm is activated and sounds an alarm, and cutting is stopped.

[0071] See also Figures 1 to 9 In an optional embodiment of the present invention, before cutting, the spindle is first pasted on the surface of the substrate, the inner ring of the cutter head is buckled on the spindle, and the central fixing piece 320 is pressed on the upper end of the spindle to fix the center point.
