Description

Technical Field

[0001] The present invention relates to the field of stainless steel tableware processing, and in particular to a method for processing stainless steel tableware. Background Art

[0002] Existing stainless steel tableware, especially stainless steel forks, needs to be polished during the production process to remove burrs and tiny knife marks on the surface, improve the appearance and texture of the fork, and prevent scratches on the hands and mouth during use. In most cases, the focus of fork use is on whether the outer side of the tip of the fork tine or the outer surface of the fork is smooth, while the smoothness of the inner side is often ignored. As long as there are no large burrs on the inner side, it is acceptable. Secondly, forks are usually relatively thin, and the inner shear surface of the fork tine has formed an acceptable surface during stamping. Therefore, in the stamping process of existing stainless steel forks, there is no polishing of the inner side of the fork tine. However, for high-end tableware, even the smallest burrs on the inner side of the fork tine will easily hide dirt and are difficult to clean. The existing stamping process of stainless steel forks cannot meet the safety requirements of high-end tableware. Summary of the Invention

[0003] The purpose of the present invention is to provide a method for processing stainless steel tableware to solve the problem that the existing stamping process of stainless steel forks cannot meet the safety requirements of high-end tableware because the inner side of the fork tines is not polished. The specific technical solution is as follows:

[0004] A method for processing stainless steel tableware comprises the following steps:

[0005] S1. Cutting the stainless steel coil into blanks;

[0006] S2. Use a fixture to match the material trough to fix the blank;

[0007] S3. Punching and cutting the fork tine tips on the blank, and simultaneously grinding the inner side of the fork tine tips at the moment the punching is completed;

[0008] S4, grinding the surface of the blank;

[0009] S5, feeding the blank into a punching machine for bending to form a fork;

[0010] S6. Use an ultrasonic cleaner to clean the fork.

[0011] As one of the improvements of the above technical solution, in step S3, a tool punch is used to punch and cut the blank to form several fork tine tips arranged side by side. At the moment when the tool punch leaves the blank after punching, the inner side surfaces of two adjacent fork tine tips are polished by a grinding mechanism. The punching head of the tool punch first moves downward to punch and cut the blank. After completing the punching and cutting, the punching head moves upward. When the punching head leaves the blank, the grinding mechanism synchronously enters between the two adjacent fork tine tips for grinding.

[0012] As one of the improvements to the above technical solution, the blank is first transported to the material trough of the platform, and then the blank is fixed using a clamp in conjunction with the material trough. A channel for recycling waste is reserved on the platform, and the waste generated during the stamping and cutting process falls into the channel.

[0013] As one of the improvements of the above technical solution, in step S4, the blank is put into the grinder, and the grinder is started, so that the multiple grinding balls in the grinder repeatedly collide and rub with the blank.

[0014] As one of the improvements of the above technical solution, in step S6, water is first added to the cleaning tank of the ultrasonic cleaning machine, and the water temperature is controlled at 40-60°C. After the fork is placed in the cleaning tank, the ultrasonic cleaning machine is started.

[0015] As one of the improvements of the above technical solution, in step S6, after the fork is cleaned by using an ultrasonic cleaning machine, the fork is dried by using a drying device.

[0016] As one of the improvements of the above technical solution, in step S3, the grinding mechanism is rotatably connected to the platform, and the grinding mechanism has a trigger end, and the trigger end is arranged in the channel. When the waste falls into the channel, it is affected by the gravity of the waste itself and falls on the trigger end, thereby pressing down the grinding mechanism to rotate and drive the grinding mechanism to enter between the two adjacent fork tooth tips.

[0017] As one of the improvements of the above technical solution, in step S3, the grinding mechanism includes a grinding head, and the grinding head includes a motor and a grinding wheel coaxially connected to the rotating shaft of the motor.

[0018] As one of the improvements of the above technical solution, the waste material stays on the trigger end of the grinding mechanism for a short time and then slides off the trigger end. After the waste material slides off the trigger end, the grinding mechanism is reset.

[0019] As one of the improvements of the above technical solution, in step S2, the clamp is pressed onto the material trough and the blank, and the clamp cooperates with the material trough to fix the blank in multiple directions.

[0020] The beneficial effects of the present invention are as follows: the present invention grinds the inner side of the fork tines by synchronously triggering the grinding mechanism during the punching and cutting process, thereby solving the problem of burrs and rough surfaces on the inner side of the fork tines in traditional stainless steel fork processing. The present invention significantly improves the smoothness and density of the inner wall or inner side of the fork tines, reduces micropores and micro cracks, and effectively reduces the risk of bacterial growth. The present invention is particularly suitable for use in medical and catering environments where tableware hygiene requirements are extremely high.

[0021] Compared with the traditional process, the present invention uses the weight of the waste to trigger the grinding mechanism for grinding, eliminating manual operation, reducing labor intensity, and improving the degree of automation and production efficiency;

[0022] The present invention adopts a frustum-shaped grinding wheel in combination with the arc-shaped motion trajectory of the support rod, which can accurately adapt to the gradually narrowing space structure between the fork teeth, ensuring that the inner surface of the fork teeth is evenly ground as a whole, avoiding the problem that the traditional cylindrical grinding wheel is difficult to fully contact, further improving the grinding quality, and enhancing the processing quality of stainless steel tableware.

[0023] In addition, by setting grinding balls in the grinder for surface treatment, and using ultrasonic cleaning combined with warm water washing, no-load rinsing and subsequent drying steps, the overall surface of the fork is smooth and free of residual stains and particles, which improves the consistency and cleanliness of the finished product, and enhances the final quality and safety of the product.

Of course, it is not necessary to achieve all of the advantages described above at the same time to implement any product or method of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0036] Existing high-end tableware has higher requirements than ordinary tableware. For example, stainless steel forks are usually required to have no large burrs on the tips of the tines.

[0037] Based on the problem that the existing stamping process of stainless steel forks cannot meet the safety requirements of high-end tableware because the inner side of the fork tines is not polished, the present invention provides some embodiments to solve the above technical problems. Figures 1-8 In an embodiment of the present invention, a method for processing stainless steel tableware includes the following steps:

[0038] S1. Material pretreatment: Select the stainless steel coil and perform annealing treatment to eliminate internal stress and ensure the quality and dimensional stability of the subsequent cutting section. Then use a punch press or laser cutting machine to cut the stainless steel coil into rectangular or approximately fork-shaped blanks;

[0039] S2. The blank is conveyed to the platform 1. The platform 1 is provided with a trough 9 for accommodating the blank. A clamp 10 is used to match the trough 9 to fix the blank. The clamp 10 matches the trough 9 to fix the blank in multiple directions. Specifically, the inner side of the trough 9 can limit the blank from the left and right sides, while the bottom surface of the trough 9 matches the clamp 10 to limit the blank from the upper and lower ends, which is convenient for subsequent punching, cutting and grinding. The front end of the trough 9 is provided with an opening 91 connected to the outside to facilitate the subsequent grinding mechanism to enter the grinding fork tip;

[0040] S3, using a tool punch to punch and cut the blank to form a plurality of fork tine tips arranged side by side, and using a grinding mechanism 5 to grind the inner side surfaces of two adjacent fork tine tips at the moment the tool punch leaves the blank after punching;

[0041] It is understandable that if you want to grind the inner side of the fork tine tip, the traditional processing technology is generally: after the fork tine tip is formed, the blank is unloaded from the platform 1, and then a special grinding device is used to grind it manually or with a multi-axis robot arm. However, in this process, since the fork tine tip has been formed, if you want to grind it further, you need to design a matching precision fixture 10 to fix the fork tine tip, that is, the entire processing flow needs to first fix the blank, punch and cut out the fork tine tip, and then fix the blank a second time before grinding the inner side of the fork tine tip. Obviously, the traditional The processing technology requires multiple fixation of the blank, and even the design of matching clamping tools for this purpose. The whole process is relatively cumbersome, the processing efficiency is low, and even the corresponding cost of the clamping tools is required. All of the above may become factors that hinder manufacturers from producing high-quality stainless steel forks. In this embodiment, only one fixation is required through the material trough 9 and the clamp 10 to complete the punching, cutting and grinding of the inner side of the fork tip. The structure of the clamp 10 is also relatively simple, and it only needs to press part of the material trough 9 and the blank. Compared with the traditional processing technology, the efficiency is better and the cost is lower.

[0042] S4. Use a grinder to grind the surface of the blank that forms the tip of the fork tine to remove the burrs and minor deformations remaining after stamping, improve the surface smoothness, and avoid scratches during use;

[0043] S5. Feed the blank into a punching machine for bending to form a fork. Specifically, the ground blank is placed in a bending die, and the upper die is pressed downward to cause the fork arms on both sides to undergo plastic deformation along a set bending line.

[0044] S6. Use an ultrasonic cleaner to clean the fork. 26–40kHz high-frequency sound waves create a cavitation effect in the cleaning fluid. The collapse of tiny bubbles creates a violent impact, removing oil and particles from the surface and crevices.

[0045] It is understandable that, because the stamping and forming process of traditional stainless steel forks does not polish the inner side of the tines, burrs are likely to remain on the inner side of the tines, which is easy to hide dirt and grime, especially small particles and liquid residues sandwiched between the tines. Medical scenes require that tableware is extremely clean, otherwise it is easy to become a breeding ground for bacteria. Polishing the inner side makes the inner wall surface of the tines smooth and dense, reduces micropores and microcracks, improves the cleaning effect during ultrasonic cleaning, and reduces the places where bacteria hide from the source. The present invention polishes the inner side of the tines by synchronously triggering the polishing mechanism 5 during the stamping and cutting process, thereby solving the problem of burrs and rough surfaces on the inner side of the tines in the traditional stainless steel fork processing, significantly improving the smoothness and density of the inner wall or inner side of the tines, reducing micropores and microcracks, and effectively reducing the risk of bacterial growth. It is particularly suitable for scenes such as medical treatment and catering that have extremely high requirements for tableware hygiene.

[0046] In order to cooperate with the implementation of the above-mentioned processing method, the invention also provides a tool punching machine equipped with a grinding mechanism 5, including a platform 1, a frame 2, a hydraulic cylinder 3, a punching head 4 and a grinding mechanism 5, wherein the platform 1 is mainly used to place the stainless steel fork. Preferably, a material trough 9 is provided on the platform 1, and the material trough 9 is used to guide and accommodate the blank, so as to prevent the blank from deviating during subsequent processing and thus affecting the processing accuracy; a channel for recycling waste is reserved on the platform 1, and the waste generated during the punching and cutting process falls into the channel. Specifically, when the tool punching machine is used to punch and cut the blank to form fork tines, the waste generated during the formation of the fork tines (punched and cut by the tool) will fall downward under the influence of its own weight in the absence of support, thereby completing the collection of the waste;

[0047] Regarding stamping and cutting, specifically, the platform 1 is horizontally connected to the frame 2, the hydraulic cylinder 3 is connected to the frame 2 and is above the platform 1, the telescopic end of the hydraulic cylinder 3 is set downward, and the punching head 4 is connected to the telescopic end of the hydraulic cylinder 3. By driving the telescopic end of the hydraulic cylinder 3 to make up and down reciprocating motions, the punching head 4 can be driven to complete a round of stamping and cutting; the punching head 4 of the tool punching machine first moves downward to punch and cut the blank, and when the punching head 4 moves upward after completing the stamping and cutting, the grinding mechanism 5 synchronously enters between the two adjacent fork tine tips for grinding.

[0048] The grinding mechanism 5 is rotatably connected to the platform 1. The grinding mechanism 5 has a trigger end, and the trigger end is arranged in the channel. When the waste falls into the channel, it is affected by the gravity of the waste itself and falls on the trigger end, thereby driving the grinding mechanism 5 to rotate, so that the grinding mechanism 5 enters between the tips of two adjacent fork teeth. Compared with the traditional process, the present invention uses the weight of the waste to trigger the grinding mechanism 5 for grinding, eliminating manual operation, reducing labor intensity, and improving the degree of automation and production efficiency.

[0049] Preferably, the grinding mechanism 5 includes a bent support rod 51, the middle end of the support rod 51 is hinged to the frame 2, and the support rod 51 is vertically arranged. The top of the support rod 51 is connected to the grinding head 52, and the bottom end of the support rod 51 is bent, and the inner side of the bottom end of the support rod 51 forms an arc-shaped bending surface. By default, the support rod 51 is tilted to the left, so that the grinding head 52 is located on the side of the platform 1, and the bottom end of the support rod 51 (specifically the bending surface) is below the channel (or the channel is reserved with an opening sufficient to accommodate the support rod 51 so that the bottom end of the support rod 51 enters the channel);

[0050] When the waste material generated during the forming process of the fork tines (punched and cut by the tool) falls down along the channel under the influence of its own weight in the absence of support, the waste material will fall directly onto the bent surface of the support rod 51. By default, the support rod 51 is tilted and kept balanced, or the top end of the support rod 51 is heavier than the bottom end of the support rod 51, and the support rod 51 tends to tilt to the left. The frame 2 is equipped with a limiter to keep the support rod 51 tilted. When the waste material falls onto the bent surface of the support rod 51, the balance of the support rod 51 will be broken, causing the support rod 51 to rotate slightly (that is, slightly to the right). It can be understood that since the weight of the waste material cut from the blank is relatively limited, it is actually not enough to drive the entire support rod 51 to rotate at a large angle. In order to realize that the waste material drives the support rod 51 to rotate at a large angle to complete the grinding of the inner side of the fork tines, the present invention also provides some embodiments:

[0051] Specifically, a magnet component 6 is connected to the frame 2, and the magnet component 6 is located below the top end of the support rod 51 (in an inclined state), and on the rotation path of the bottom end of the support rod 51, the magnetic field coverage range of the magnet component 6 is just 2-10 mm away from the bottom end of the support rod 51 (in an inclined state), and the material of the bottom end of the support rod 51 is a solid metal that can be attracted by a magnet. Therefore, as long as the bottom end of the support rod 51 is slightly rotated downward or to the left by the gravity of the waste, the bottom end of the support rod 51 is easy to enter the attraction range of the magnet component 6, and the magnet component 6 will attract the bottom end of the support rod 51, so that the bottom end of the support rod 51 gradually approaches the magnet component 6, and finally the bottom end of the support rod 51 is attracted to the magnet component 6. In this process, the grinding head 52 at the top end of the support rod 51 will enter between the two adjacent fork teeth for grinding, and the waste will slide off the trigger end after a short stay, and the waste will slide off the bending surface;

[0052] Considering that the openings between adjacent fork teeth are gradually narrowed from the outside to the inside, and based on the connection method and driving method of the support rod 51, it can be seen that the support rod 51 is actually rotating, that is, the movement trajectory of the grinding head 52 is arc-shaped, then the ordinary grinding head 52 is not suitable for this embodiment. Specifically, the grinding head 52 usually includes a motor 521 and a grinding wheel 522 coaxially connected to the rotating shaft of the motor 521. Generally, the grinding wheel 522 is cylindrical or flat cylindrical, and the openings between adjacent fork teeth are gradually narrowed from the outside to the inside, indicating that the ordinary grinding wheel 522 does not match this shape. Therefore, the present invention further provides some embodiments to solve the above problems. Specifically, the grinding wheel 522 is in a frustum-conical shape, that is, the grinding wheel 522 is narrow at the top and wide at the bottom. When the grinding head 52 approaches and enters between adjacent fork teeth, the bottom of the grinding wheel 522, that is, the wider part, first contacts the inner side of the fork teeth. As the support rod 51 rotates, the grinding head 52 will penetrate deeper into the space between the adjacent fork teeth. Since the movement trajectory of the grinding head 52 is arc-shaped, the contact with the inner side of the fork teeth will gradually shift from the bottom of the grinding wheel 522 to the top of the grinding wheel 522. Only the frustum-conical grinding wheel 522 can grind the inner side of the fork teeth.

[0053] A magnet component 6 is provided for adsorbing and stabilizing the support rod 51 during the grinding process, thereby preventing the accuracy from being affected by rebound during the grinding process. A rope 8 is used to connect the punch head 4 and the top of the support rod 51, so that the support rod 51 is automatically reset during the lifting process of the punch head 4, so that the grinding mechanism 5 can be ready for the next round of processing in time after each round of punching and cutting, thereby ensuring continuous production and reducing the failure rate. The present invention adopts a frustum-shaped grinding wheel 522 in conjunction with the arc-shaped motion trajectory of the support rod 51, which can accurately adapt to the gradually narrowing space structure between the fork tines, ensuring that the inner side surface of the fork tines is evenly ground as a whole, avoiding the problem that the traditional cylindrical grinding wheel 522 is difficult to fully contact, and further improving the grinding quality.

[0054] Furthermore, in order to achieve automation, a proximity switch 9 can be provided on the bracket, and the proximity switch 9 is connected to the signal of the motor 521, and a trigger member 10 that can be used to trigger the proximity switch 9 is connected to the side of the bottom end of the support rod 51. When the support rod 51 rotates, the trigger member 10 will trigger the proximity switch 9 and automatically start the motor 521.

[0055] In addition, although the above embodiment can be used to drive the support rod 51 to drive the grinding head 52 to automatically grind the inner side of the fork teeth, due to the adsorption of the magnetic component 6, the support rod 51 cannot be reset, and the above structure cannot be reused for repeated operations, or the support rod 51 needs to be manually reset, which is more troublesome. For this reason, the present invention also provides some embodiments. Specifically, a servo motor is installed on the frame 2, and the rotating shaft of the servo motor is connected to the support rod 51. The servo motor is connected to the proximity switch 9 signal. When the proximity switch 9 is triggered by the trigger member 10, the servo motor will start with a delay. Specifically, the starting timing of the servo motor is when the punching head 4 leaves the blank, and the servo motor will drive the support rod 51 to rotate a certain angle, so that the grinding head 52 is separated from the blank or the bottom end of the support rod 51 is separated from the magnet part, thereby completing the reset.

[0056] In some embodiments, the grinding machine in step S4 is provided with a cavity inside, and a plurality of grinding balls are provided in the cavity. After the blank enters the accommodation space, the grinding machine is started, and the cavity rotates, vibrates or stirs, so that the plurality of grinding balls repeatedly collide and rub against the blank.

[0057] In step S6, water is first added to the cleaning tank of the ultrasonic cleaning machine, and the water temperature is controlled at 40-60°C. After the fork is placed in the cleaning tank, the ultrasonic cleaning machine is started. After the fork is cleaned by the ultrasonic cleaning machine, the fork is dried using a drying device. Preferably, in step S6, the ultrasonic cleaning machine performs a no-load ultrasonic rinse of the cleaning tank after each batch of forks is cleaned; in the ultrasonic cleaning step, the water temperature is controlled at 40-60°C, and the high-frequency cavitation effect is used to deeply clean the gaps between the fork teeth, and a no-load rinse procedure is performed after each batch of cleaning, effectively preventing residual particles or oil in the cleaning tank from contaminating the next batch of products, thereby improving the cleaning effect and consistency between batches. By setting grinding balls in the grinder for surface treatment, and using ultrasonic cleaning in combination with temperature water washing, no-load rinse and subsequent drying steps, the overall surface of the fork is smooth and free of residual stains and particles, thereby improving the consistency and cleanliness of the finished product, and improving the final quality and safety of the product.

[0058] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
