Description

Technical Field

[0001] This invention belongs to the field of tool coating, and particularly relates to a composite coating device for the surface of an engraving tool. Background Technology

[0002] Wood products are generally made from complex mixtures of raw materials. Under intense cutting conditions, the surface of wood carving tools will experience varying degrees of wear, which significantly affects the roughness and precision of the finished product. Traditional wood carving tools typically use a Teflon coating to reduce this wear, but under prolonged high loads, the Teflon coating may peel off.

[0003] Patent document CN119243302B discloses an electroplating device that employs a clamping device consisting of a clamping rod and a spring, and a suspension assembly for placing metal workpieces. After the workpiece is clamped and fixed by the clamping assembly, power is supplied to the workpiece through the suspension assembly and the clamping assembly, facilitating the movement of metal ions from the anode to the workpiece surface at the cathode, thus achieving plating. This solution uses a rack plating method to uniformly plating the workpiece, but it cannot perform complex composite plating on the surface of woodworking carving tools.

[0004] Therefore, when using traditional equipment to apply this coating to wood carving knives, problems such as low integration and uneven composite coating occur, making it impossible to deposit the coating evenly on the knife surface. The process is not only cumbersome but also increases the coating cost. Summary of the Invention

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0023] As described in the background section, traditional woodworking carving knives typically use a Teflon coating to reduce wear, but under long-term high loads, the Teflon coating may peel off.

[0024] Based on this, the present invention provides a composite plating device for the surface of an engraving tool. The composite plating device for the surface of an engraving tool provided in the embodiments of the present invention will be described below first.

[0025] like Figure 1-8 As shown; Example 1; Optionally, in one example, the engraving tool surface composite plating device 100 includes: Electroplating reactor 1: Electroplating reactor 1 includes an inner tank 11, an end cap 12, a controller 13, and an anode plate 14. The inner tank 11 has a first receiving cavity 111 inside, which is used to receive the plating solution. The end cap 12 includes a cover body 121 and a cathode tool holder 122. The cover body 121 covers the opening of the first receiving cavity 111. The cathode tool holder 122 is connected to the cover body 121 and is used to connect with the tool blank and extend the tool blank into the first receiving cavity 111 so that the tool blank is immersed in the plating solution. The anode plate 14 is connected to the side wall of the first receiving cavity 111 and is immersed in the plating solution. The anode plate 14 and the cathode tool holder 122 are both connected to a power source. The controller 13 is communicatively connected to the power source. Storage tank 3: Storage tank 3 includes tank body 31 and sand pump 32. Tank body 31 is used to store plating solution and diamond particles. Controller 13 is communicatively connected to sand pump 32 and is used to control sand pump 32 to draw plating solution and diamond particles from storage tank 3 into first receiving cavity 111.

[0026] The engraving knife is an irregularly shaped tool. Its blank is fixed on a cathode tool. The cathode tool holder 122 is connected to the cover 121. When the end cap 12 is placed on the inner barrel 11, the cathode tool holder 122 also extends into the first receiving cavity 111, which contains plating solution. The controller 13 controls the power supply to energize the cathode tool holder 122 and the anode plate 14, thereby applying a pre-plating layer to the surface of the blank under electroplating. This pre-plating allows diamond particles to better adhere to the blank surface during subsequent sandblasting operations, thus improving the sandblasting effect.

[0027] After pre-plating, the tool blank undergoes a sandblasting process. Controller 13 then activates the sandblasting pump 32, which draws plating solution and diamond particles from the storage tank 3, spraying the diamond particles onto the tool blank. Since the first cavity contains plating solution, the diamond particles remain suspended in the solution and do not immediately settle. During the gradual deposition process, they fall onto the tool blank, ensuring that the diamond and nickel (plating solution) are co-deposited on the tool surface. Controller 13 stops the sandblasting pump 32, thus preventing the extraction of diamond particles from the storage tank into the first cavity 111, completing the sandblasting operation on the tool blank. The uniform co-deposition of diamond particles on the tool blank surface helps form a dense and strongly bonded composite coating, significantly improving the uniformity and adhesion of the coating, effectively preventing the coating from peeling off during use.

[0028] After the diamond particles are plated on the blank, the blank immersed in the plating solution is electroplated again to plate another layer of nickel on the blank after the sand coating is completed, so as to reinforce the plated diamond particles. After the electroplating preset time is completed, the controller 13 controls the power supply to stop, thereby completing the electroplating work of the blank to obtain the engraving knife.

[0029] Based on this, the power supply and the abrasive pump 32 are managed uniformly through the controller 13. This design achieves automated control of plating solution circulation, diamond particle replenishment, and the electroplating process, reducing human intervention and frequent workpiece clamping steps. This not only simplifies the operation process, reduces process complexity, and improves the ease of plating the engraving tool, but also helps reduce energy consumption and material waste by improving production efficiency and control precision, thereby reducing the overall plating cost.

[0030] Optionally, in one example, the electroplating reactor 1 further includes an outer tank 15, inside which a second receiving cavity 151 is formed for containing water. An inner tank 11 is placed inside the second receiving cavity 151, and a heater 16 is provided inside the second receiving cavity 151. The heater 16 is connected to a controller 13, which controls the heater 16 to start and stop.

[0031] In the above example, a second receiving cavity 151 is formed inside the outer barrel 15, and the inner barrel 11 is placed in the second receiving cavity 151. The second receiving cavity 151 is used to hold water. Before the inner barrel 11 is electroplated, the controller 13 controls the heater 16 to start, so as to heat the water in the second receiving cavity 151 through the heater 16, so that the inner barrel 11 can be in a suitable electroplating environment, thereby improving the efficiency of electroplating. In addition, a temperature sensor can also be installed in the second receiving cavity 151. The controller 13 is connected to the temperature sensor and can control the heater 16 to turn on and off according to the temperature information fed back by the temperature sensor, so that the second receiving cavity 151 is always in a suitable electroplating temperature. After the water is heated to the preset temperature, the controller 13 will be powered on to start the plating work on the blank.

[0032] Optionally, in one example, the electroplating reactor 1 further includes a first drive 17, the output end of which is connected to the inner barrel 11, and the controller 13 is communicatively connected to the first drive 17 for driving the inner barrel 11 to rotate in the second receiving cavity 151.

[0033] In the above example, by setting the first driving component 17, the controller 13 controls the first driving component 17 to rotate, thereby driving the inner barrel 11 to rotate. While the inner barrel 11 is rotating, the anode plate 14 will also rotate, thereby making the plating of the blank more uniform.

[0034] Optionally, in one example, the electroplating reactor 1 further includes an internal gear disk 18 and an external gear 19. The internal gear disk 18 is connected to the bottom of the inner barrel 11, and the output end of the first drive member 17 is connected to the external gear 19. The internal gear disk 18 and the external gear 19 mesh with each other.

[0035] In the above example, an internal gear disk 18 is provided at the bottom of the inner tub 11. The output end of the first driving member 17 is connected to the external gear 19. Thus, when the output end of the first driving member 17 rotates, it will also drive the external gear 19 to rotate. The external gear 19 meshes with the internal gear disk 18, so it will also drive the internal gear disk 18 to rotate. The internal gear disk 18 is connected to the inner tub 11, so the inner tub 11 will also rotate. By driving the inner tub 11 to rotate through the meshing of the internal gear disk 18 and the external gear 19, the rotation of the inner tub 11 can be ensured to be smooth and the reliability of the rotation of the inner tub 11 can be improved.

[0036] Optionally, in one example, the bottom of the inner barrel 11 protrudes in the direction of the outer barrel 15 to form a first annular boss, and the bottom surface of the second receiving cavity 151 protrudes in the direction of the inner barrel 11 to form a second annular boss. An annular groove is formed between the first annular boss and the second annular boss. The electroplating reactor 1 also includes a plurality of balls 20, which are placed in the annular groove.

[0037] In the above example, an annular groove is formed between the first annular boss and the second annular boss. Multiple balls 20 are arranged in the annular groove, so that when the first driving member 17 rotates through the external gear 19 and the internal gear disk 18, the inner barrel 11 and the outer barrel 15 can be rotatably connected through the balls 20, which reduces the friction force on the inner barrel 11 when rotating and improves the convenience of the first driving member 17 to drive the inner barrel 11 to rotate.

[0038] Optionally, in one example, the electroplating reactor 1 further includes a first stirrer 21 and a second drive unit 22. The stirrer is placed in the first receiving cavity 111, the output end of the second drive unit 22 is connected to the stirrer, and the second drive unit 22 is communicatively connected to the controller 13.

[0039] In the above example, the controller 13 can control the rotation or stop of the first stirrer 21 in the first receiving cavity 111 by controlling the opening or closing of the second drive component 22. During both the pre-plating and sandblasting stages, the controller 13 controls the rotation of the second drive component 22 to cause the first stirrer 21 to rotate in the first receiving cavity 111, cooperating with the rotating inner barrel 11. This allows the plating solution and diamond particles to be better stirred and mixed, increasing the contact area between the plating solution and diamond particles and the blank, thus enhancing the plating effect.

[0040] During the pre-plating stage, the first agitator 21 operates at a relatively low speed to ensure uniform composition of the plating solution and reduce the influence of pH. During the sand-coating stage, the first agitator 21 rotates at a slightly higher speed to suspend the diamond particles in the plating solution. In the hardening stage, the first agitator 21 stops to allow the diamond particles to settle, ensuring proper nickel plating hardening of the die blank.

[0041] It should be noted that during the reinforcement stage, since it is no longer necessary to coat the inner barrel with diamond particles, only the first drive component 17 needs to drive the inner barrel 11 to rotate, and the second drive component 22 no longer needs to drive the first agitator 21 to rotate.

[0042] Alternatively, in one example, the heater 16 is spirally disposed on the sidewall of the second receiving cavity 151.

[0043] In the above example, by spirally arranging the heater 16, the heater 16 can be attached to the side wall of the second receiving cavity 151, thereby increasing the contact area between the heater 16 and the water in the second receiving cavity 151 and improving the heating efficiency.

[0044] In addition, the outer tub 15 is provided with a drain outlet and a water inlet. The drain outlet is located at the bottom of the outer tub 15, which facilitates the water flow in the second receiving cavity 151 to be discharged from the drain outlet. The water inlet is located at the top of the outer tub 15, and the height of the outer side of the water inlet is higher than the height of one side of the second receiving cavity 151. This not only facilitates the water flow from the water inlet into the second receiving cavity 151, but also facilitates the discharge of water vapor generated after the water in the second receiving cavity 151 is heated through the water inlet.

[0045] Example 2: Optionally, in one example, the electroplating reactor 1 further includes: an outer electrode plate 23, graphite guide wheels 24, and conductive shoes 25; the outer electrode plate 23 is installed on the outer wall of the inner barrel 11, the number of outer electrode plates 23 is the same as that of the anode plates 14, and the outer electrode plates 23 and the anode plates 14 correspond one-to-one and are interconnected; multiple graphite guide wheels 24 are connected to the side of the outer electrode plate 23 near the end cover 12; the conductive shoes 25 are installed on the end cover 12 and connected to the power supply; the graphite guide wheels 24 and the conductive shoes 25 are interconnected; the number of conductive shoes 25 and electrode plates is multiple, and the multiple conductive shoes 25 and multiple electrode plates are distributed in a circumferential array around the central axis of the inner barrel 11.

[0046] In the above example, the conductive shoe 25 is mounted on the end cap 12. The outer electrode plate 23 and the anode plate 14 are respectively mounted on the outer wall and inner wall of the inner barrel 11. The outer electrode plate 23 and the anode plate 14 are one-to-one and mutually conductive. Multiple graphite guide wheels 24 are arranged horizontally on the side of the outer electrode plate 23 facing the end cap 12. The conductive shoe 25 can contact and conduct electricity with the graphite guide wheels 24. One outer electrode plate 23, one anode plate 14, multiple graphite guide wheels 24 and one conductive shoe 25 together constitute a power transmission group. There are multiple power transmission groups. The anode plate 14, outer electrode plate 23, and graphite guide roller 24 are arranged concentrically with the inner barrel 11 and distributed in a circumferential array. Therefore, when the inner barrel 11 rotates, the anode plate 14, outer electrode plate 23, and graphite guide roller 24 will all rotate together with the inner barrel 11. The conductive shoe 25 is installed on the end cap 12 and does not rotate together. However, during rotation, since multiple horizontal graphite guide rollers 24 are arranged, the graphite guide rollers 24 will continuously contact multiple conductive shoes 25 during rotation. This ensures that the anode plate 14 is continuously and stably powered during the rotation of the inner barrel 11, thus ensuring the stability of the electroplating of the blank.

[0047] It should be noted that the distance between any two adjacent conductive shoes 25 is less than the minimum distance between the graphite guide wheels 24 in any two adjacent transmission groups. This ensures that the graphite guide wheel 24 will always be in contact with the conductive shoe 25 and conduct current during rotation.

[0048] In the above embodiment 2, each method in the above embodiment 1 is included, and each process in the above embodiment 1 can be implemented, achieving the same technical effect. To avoid repetition, it will not be described again here.

[0049] Example 3: Optionally, in one example, the storage tank 3 further includes a lid 33 and a second stirrer 34. A third receiving cavity 311 is formed inside the tank body. The lid 33 covers the opening of the third receiving cavity 311. The lid 33 is connected to the second stirrer 34, which extends into the third receiving cavity 311. The second stirrer 34 is connected to the controller 13.

[0050] In the above example, by setting a second stirrer 34 in the storage tank 3, the second stirrer 34 can stir the plating solution and diamond particles placed in the third receiving cavity 311, reducing the possibility of diamond particles settling at the bottom of the third receiving cavity 311. Thus, during the sanding operation, the sanding pump 32 draws a mixture of plating solution and diamond particles from the third receiving cavity 311, so that the diamond particles can be sprayed onto the blank, thereby improving the sanding effect.

[0051] In addition, the third drive unit 36 ​​can be used to control the second stirrer 34 to stir the third receiving cavity 311. At the same time, the third drive unit 36 ​​is connected to the controller 13, which can control the third drive unit 36 ​​to turn on or off, so that the second stirrer 34 can start or stop.

[0052] During the sand-coating stage, controller 13 controls the second stirrer 34 to stir the plating solution and diamond particles in the third receiving cavity 311. Controller 13 then controls the sand-coating pump 32 to start, so that the sand-coating pump 32 can draw the mixed suspension of plating solution and diamond from the third receiving cavity 311 through the sand-coating pipe 41. During the hardening stage, the second stirrer 34 first stops rotating to allow the diamond particles in the third receiving cavity 311 to settle down. Then the first stirrer 21 stops rotating to allow the diamond particles in the first receiving cavity 111 to also settle down. At this time, the diamond particles in the first receiving cavity 111 and the third receiving cavity 311 have both settled down, so as to ensure that when the blank is hardened in the first receiving cavity 111, it is plated with nickel and no longer contains diamond particles.

[0053] Optionally, in one example, the engraving tool surface composite plating device 100 further includes a connecting pipe 4, and the liquid storage tank 3 further includes a water pump 35. The water pump 35 is communicatively connected to the controller 13. The connecting pipe 4 includes an upper sand pipe 41 and a water pump 42. One end of the upper sand pipe 41 and one end of the water pump 42 are both connected to the liquid storage tank 3. The other end of the upper sand pipe 41 and the other end of the water pump 42 extend into the first receiving cavity 111. The other end of the upper sand pipe 41 is directly opposite the cathode tool holder 122. The depth of the upper sand pipe 41 extending into the first receiving cavity 111 is less than the depth of the water pump 42 extending into the first receiving cavity 111. The upper sand pump 32 is connected to the upper sand pipe 41, and the water pump 35 is connected to the water pump 42.

[0054] In the above example, the first receiving cavity 111 of the inner tank 11 and the third receiving cavity 311 of the liquid storage tank 3 are connected by a connecting pipe 4. The connecting pipe 4 includes an upper sanding pipe 41 and a lower water pumping pipe 42. The two ends of the lower water pumping pipe 42 and the upper sanding pipe 41 are respectively connected to the first receiving cavity 111 and the third receiving cavity 311. The controller 13 controls the upper sanding pump 32 to start. The upper sanding pump 32 draws the plating solution and diamond particles in the third receiving cavity 311 into the first receiving cavity 111 through the upper sanding pipe 41. The upper sanding pipe 41 extends further into the first receiving cavity 111 than the lower water pumping pipe 42 and is directly facing the blank, thereby directly spraying diamond particles onto the blank and improving the blank's performance. The sanding effect is achieved; at the same time, the controller 13 will also control the water pump 35 to start, and the water pump 35 will pump the plating solution from the first receiving cavity 111 back to the third receiving cavity 311 through the water pump pipe 42. Since the water pump pipe 42 is located above the first receiving cavity 111, the diamond particles will be less present above the first receiving cavity 111 due to weight issues. Therefore, the water pump pipe 42 will pump the plating solution back to the third receiving cavity 311. Thus, the sanding pump 32, sanding pipe 41, water pump 35 and water pump pipe 42 together form a circulation loop in the first receiving cavity 111 and the third receiving cavity 311 to ensure the uniformity of diamond particles on the surface of the blank.

[0055] In the above embodiment 3, each method in the above embodiment 1 and / or 2 is included, and each process in the above embodiment 1 and / or 2 can be implemented to achieve the same technical effect. To avoid repetition, it will not be described again here.
