Description

Technical Field

[0001] The invention belongs to the technical field of stainless steel tableware processing, and particularly relates to a method for processing stainless steel tableware. Background Art

[0002] Currently, the polishing process for stainless steel cutlery such as knives, forks, and spoons mainly relies on manual or automatic polishing machines. The standardized process is usually divided into three stages: first, a coarse-grained polishing wheel is used in combination with polishing paste to remove burrs and surface unevenness, then a medium-grained polishing wheel is used to further smooth the surface, and finally a fine-grained polishing wheel is used to achieve a mirror effect. This method is highly efficient in the mass production of standard tableware, but when faced with high-end customized tableware, such as carved fork handles, curved spoon bodies, and special-shaped knives, the mechanical structure defects of traditional manual or automatic polishing machines gradually become apparent.

[0003] The mechanical structure of traditional automatic polishing equipment is usually designed for fixed-axis rotation or linear reciprocating motion, which limits the motion trajectory of the polishing head and makes it difficult to evenly cover the depressions, edges and fine lines of complex geometric shapes, resulting in inconsistent surface gloss after polishing, blurred details, and even damage to fine structures due to local over-polishing. In addition, manual polishing machines require frequent manual intervention, such as manual angle adjustment or rework, which is not only inefficient but also increases production costs and the risk of quality fluctuations. In response to the above problems, the inventors have proposed a new method for processing stainless steel tableware, which can polish the surfaces of stainless steel tableware such as knives, forks and spoons at multiple angles, and adapt to the multi-directional polishing requirements of complex surfaces such as high-end customized knives, forks and spoons through a multi-degree-of-freedom motion polishing head, thereby improving processing accuracy while reducing dependence on manual experience.

[0030] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0031] See also Figure 1 - Figure 5 This embodiment provides a method for processing stainless steel tableware, comprising the following steps:

[0032] S1: Pretreatment: Fix the stainless steel cutlery, including knife, fork and spoon, in a fixture, and perform ultrasonic cleaning to remove oil and impurities on the surface of the cutlery. Then, perform pickling or sandblasting to remove the oxide layer.

[0033] S2: Rough polishing: Using a coarse-grained polishing wheel and polishing paste, the tableware surface is roughly polished at multiple angles using a multi-degree-of-freedom polishing device to remove burrs and surface unevenness. In addition, the actual operation also involves system control. It is necessary to generate multi-axis linkage trajectories based on the three-dimensional models of the knife, fork, and spoon. The polishing head 9 is driven by the CNC system to cover multiple angles along the preset path, and the position data is fed back in real time to correct the trajectory deviation. The movement of the polishing head 9 is controlled by a servo motor and a harmonic reducer to ensure uniform grinding of recesses and edges.

[0034] S3: Medium polishing: Replace the medium-grit polishing wheel and use the multi-degree-of-freedom polishing device to dynamically adjust the polishing angle and pressure to smooth the surface of the tableware. In addition, in terms of system control, it is necessary to integrate pressure sensors and angle encoders to collect contact pressure and angle information in real time through a closed-loop control algorithm, and adaptively adjust the downward force and inclination angle of the polishing head 9. In addition, it is necessary to use a PID controller to dynamically match the changes in surface curvature to avoid local overpressure or under-polishing.

[0035] S4: Fine polishing uses a fine-grained polishing wheel and multi-degree-of-freedom polishing equipment to move along the complex curved surfaces of knives, forks, and spoons to achieve a mirror-like effect. In addition, in terms of system control, the surface trajectory is generated based on high-precision model data, and continuous path planning is achieved through interpolation algorithms to ensure a consistent mirror effect.

[0036] S5: Post-processing, cleaning polishing residues, wiping the surface with alcohol, and using instruments to detect gloss and flatness. Among them, the polishing head 9 of the multi-degree-of-freedom polishing equipment uses multi-axis collaborative control and adaptive algorithms to achieve full coverage polishing of complex geometric shapes, and the process parameters between each step are seamlessly connected through the central control system.

[0037] At present, in the polishing process of stainless steel tableware such as knives, forks and spoons, traditional manual and automatic polishing machines are difficult to meet the polishing requirements of complex surfaces and fine structures of high-end customized tableware due to mechanical structure limitations, resulting in uneven surface gloss and quality fluctuations. In order to solve this problem, in one embodiment, the scheme adopts multi-degree-of-freedom polishing equipment to achieve multi-angle polishing of the surface of stainless steel tableware, avoids uneven polishing caused by manual adjustment, improves the processing quality of stainless steel tableware, and improves the surface gloss of stainless steel tableware. Combined with high-precision three-dimensional models and adaptive algorithms, efficient and uniform polishing of complex surfaces and fine structures of stainless steel tableware such as knives, forks and spoons is achieved. By precisely controlling the multi-axis linkage trajectory, pressure and angle of the polishing head 9 and dynamically adjusting the polishing process parameters, the problems of uneven surface gloss and quality fluctuations caused by mechanical structure limitations in the prior art are solved, thereby meeting the high-standard polishing requirements of high-end customized tableware.

[0038] In order to better meet the high-standard polishing requirements of high-end customized tableware, in one embodiment, a multi-degree-of-freedom polishing device includes an equipment body 1, a vertical polishing part 2 slidingly arranged on the equipment body 1, a horizontal polishing part 3, a first rocker part 4 and a second rocker part 5, a polishing head 9 is provided on the horizontal polishing part 3, one end of the first rocker part 4 and one end of the second rocker part 5 are connected by a swinging part 6, the swinging part 6 is provided on the equipment body 1, the other end of the first rocker part 4 is connected to one end of the vertical polishing part 2, the horizontal polishing part 3 is slidably arranged on the other end of the vertical polishing part 2, and the horizontal polishing part 3 is connected to the other end of the second rocker part 5, the first rocker part 4 is connected to a driving member 10, the vertical polishing part 2 drives the horizontal polishing part 3 to move back and forth synchronously, the vertical polishing part 2 drives the swinging part 6 to swing through the first rocker part 4, and the swinging part 6 drives the horizontal polishing part 3 to move back and forth horizontally through the second rocker part 5, so that the polishing head 9 has multiple degrees of freedom to adapt to the multi-directional polishing requirements of complex curved surfaces such as knives, forks and spoons;

[0039] Among them, the polishing head 9 here can be adjusted to an angle of 30°-60° with the horizontal plane, ensuring that the polishing head 9 can also change its angle by 30°-60° with the horizontal plane while moving up, down, left and right, so as to adapt to every corner and curved surface of the knife, fork and spoon, thereby achieving a comprehensive and uniform polishing effect; the polishing head 9 realizes angle adjustment through the hinged design of the mounting hole and the sliding plate, and is fixed by bolts or clamps after adjustment, wherein the angle fixation is an implicit technical feature, which can be reasonably implemented by those skilled in the art.

[0040] One thing that needs to be explained is that, in this embodiment, the driving member 10 of the first rocker portion 4 enables the vertical polishing portion 2 to move back and forth up and down, and the swinging of the swinging portion 6 enables the vertical polishing portion 2 to swing left and right. At the same time, the horizontal reciprocating motion of the horizontal polishing portion 3 and the cooperation of the second rocker portion 5 enable the polishing head 9 to move in the horizontal direction. These movements combined can realize flexible movement of the polishing head 9 in three-dimensional space. The first rocker portion 4 and the second rocker portion 5 are connected by the swinging portion 6, so that the swinging portion 6 can accurately control the movement of the vertical polishing portion 2 and the horizontal polishing portion 3. The control of the driving member 10 can accurately adjust the swinging amplitude and frequency of the rocker portion, thereby realizing precise control of the motion trajectory of the polishing head 9. Finally, the polishing head 9 can adapt to complex curved surfaces. Therefore, when polishing knives, forks, and spoons, pressure can be applied more evenly, thereby improving the polishing quality. In addition, the synchronous movement of the vertical polishing portion 2 and the horizontal polishing portion 3 enables the polishing head 9 to cover every corner and curved surface of the object, thereby achieving a comprehensive and uniform polishing effect.

[0041] Since the polishing head 9 will generate vibration and cause the polishing head 9 to shake when polishing the cutlery, fork and spoon, in order to avoid the polishing head 9 from deflecting or shaking during the vertical movement and ensure the linear accuracy of the up and down movement, in one embodiment, the vertical polishing part 2 includes a limit frame 21, a sliding rod 22 and a support rod 23, and the two ends of the sliding rod 22 are respectively vertically connected to the support rod 23 and the limit frame 21, and a slider 7 is provided on the device body 1, and the sliding rod 22 is slidably set on the slider 7. The vertical polishing part 2 cooperates with the limit frame 21, the sliding rod 22 and the support rod 23, and the sliding rod 22 is on the slider 7 of the device body 1. Sliding, forming a stable vertical motion guide, the vertical connection between the limit frame 21 and the sliding rod 22 limits the movement direction, avoids the polishing head 9 from offsetting or shaking during vertical movement, and ensures the linear accuracy of the up and down movement. The vertical connection between the support rod 23 and the sliding rod 22 forms a rigid frame, which enhances the strength of the mechanical structure and prevents deformation caused by polishing pressure. The sliding design of the sliding rod 22 on the slider 7 reduces the size of the equipment and realizes a large range of vertical movement to meet the polishing needs of tableware of different sizes. In addition, high-precision vertical movement is achieved through mechanical constraints, providing a stable foundation for the subsequent superposition of horizontal and swinging movements.

[0042] It is worth mentioning that, since the cutlery is customized for high-end products, the precision requirement is higher than that for ordinary cutlery, and the error required for complex curved surfaces such as knives, forks and spoons is smaller. Therefore, when polishing, there will be a delay problem when converting between multiple degrees of freedom, which will easily lead to a decrease in polishing accuracy. In order to solve this problem, in one embodiment, the first rocker part 4 includes a rotating wheel 41, a crank rod 42 and a first rocker 43 arranged in the limit frame 21, one end of the crank rod 42 is arranged at the eccentricity of the rotating wheel 41, and one end of the crank rod 42 is connected to the driving member 10, the other end of the crank rod 42 is hinged to one end of the first rocker 43, and the other end of the first rocker 43 is hinged to one end of the swinging part 6, the swinging part 6 is a swinging rod, and the center of the swinging rod is rotatably set on the equipment body 1 through the rotating seat 8. The limit frame 21 is a flat groove structure, and the diameter of the rotating wheel 41 is the same as the width of the flat groove structure limit frame 21. Figure 3 As shown, the driving member 10 here is a servo motor. The driving member 10 drives the rotating wheel 41 to eccentrically rotate in the limit frame 21 through the crank rod 42, and then transmits power through the hinge of the first rocker 43 and the swing part 6, forming the up and down movement of the vertical polishing part 2 and the linkage of the swing part 6. The mechanical limit of the rotating wheel 41 and the rigid connection of the crank rod 42 avoid the transmission delay problem and ensure the real-time synchronization of multi-degree-of-freedom movement. In addition, the diameter of the rotating wheel 41 is the same as the width of the limit frame 21. The purpose is to ensure that the rotating wheel 41 rolls without gaps in the flat groove, reducing energy loss and vibration. The position of the driving member is fixed on the main body of the equipment.

[0043] In addition, in order to ensure that the second rocker part 5 can move stably along the horizontal direction while moving up and down synchronously with the first rocker part 4, in an embodiment, the second rocker part 5 comprises a second rocker 51, a connecting rod 52 and a sliding plate 53, the sliding plate 53 is slidingly arranged on the support rod 23, one end of the connecting rod 52 is fixedly connected with the sliding plate 53, the other end of the connecting rod 52 is hingedly connected with one end of the second rocker 51, the other end of the second rocker 51 is hingedly connected with the other end of the swing part 6, the support rod 23 is provided with a trapezoidal groove 231, the sliding plate 53 is of a trapezoidal structure, the trapezoidal structure of the sliding plate 53 is slidingly arranged in the trapezoidal groove 231, the sliding plate 53 is provided with a mounting hole, the polishing head 9 is arranged in the mounting hole, and the polishing end of the polishing head 9 is of an arc structure, the sliding plate 53 is matched with the support rod 23 through the trapezoidal groove 231, the connecting rod 52 is hingedly connected with the second rocker 51, the swing of the swing part 6 is converted into the horizontal reciprocating motion of the horizontal polishing part 3, the trapezoidal structure of the sliding plate 53 is matched with the trapezoidal groove 231 of the support rod 23, a self-locking guide is provided, the polishing head 9 is prevented from deviating due to inertia in the horizontal motion, the trajectory accuracy is ensured, the arc polishing end of the polishing head 9 and the mounting hole of the sliding plate 53 are designed, so that the arc polishing end can be attached to the concave-convex curved surface of the tableware in the horizontal motion, the dead angle of polishing is avoided, the hinged connection between the sliding plate 53 and the connecting rod 52 allows the polishing head 9 to adaptively fine-tune the angle in the horizontal motion, and the pressure is uniformly distributed through the combination of the PID controller.
