Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, specifically to an electroplating device for producing corrosion-resistant fastening screws. Background Technology

[0002] Fastener electroplating is a surface treatment process that involves plating a layer of metal onto the surface of fasteners to improve their corrosion resistance, hardness, and aesthetics.

[0003] Chinese patent CN221460562U discloses an alloy manufacturing surface coating device for electroplating metal parts.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: In actual use, the metal parts are laid flat on a tray and immersed in the electrolyte for electroplating. The side blocked by the tray does not have sufficient contact with the electrolyte, resulting in uneven electroplating on the outer end face of the metal parts.

[0005] This invention proposes an electroplating device for producing corrosion-resistant fastening screws to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to clamp and fix the top and bottom of the fastener by using a top and bottom clamping and limiting method, so as not to block the thread structure of the outer arc surface of the fastener, thus ensuring the uniformity and integrity of the electroplating process of this device, thereby overcoming the problems in the background art mentioned above.

[0007] Based on the above technical concept, the technical solution adopted by this utility model is as follows: An electroplating device for producing corrosion-resistant fastening screws includes a housing, a circulation component connected to the outer side of the housing, a cover plate connected to the top of the housing, an electroplating component connected to the top of the cover plate, a lifting component connected to the top of the cover plate, and a vertically penetrating lifting groove provided at the center of the cover plate.

[0008] Further defining the above technical solution, the circulation component includes a water pump connected to the side of the housing. The water pump inlet is connected to an inlet pipe that penetrates the bottom of the side of the housing. The other end of the water pump is connected to an outlet pipe that penetrates the top of the housing on the side away from the inlet pipe. The water pump enables the electrolyte inside the housing to circulate. This circulation improves the uniformity of electrolyte ion distribution and ensures that the electroplating process does not lead to a decrease in the local ion concentration of the electrolyte.

[0009] Further defining the above technical solution, the electroplating component includes an ionization generator connected to the top of the cover plate. The ionization generator is electrically connected to a conductive element, and a conductive sensor is connected to the side of the ionization generator. The conductive sensor is electrically connected to the conductive element, and the bottom of the conductive element extends into the housing. The combination of the conductive element and the ionization generator enables the electrolyte electroplating effect of this device. The structure of the conductive sensor allows for the detection of the conductivity of the electrolyte, thereby determining the internal ion concentration and allowing for timely replacement of the electrolyte based on the degree of conductivity decrease.

[0010] Further defining the above technical solution, the lifting component includes an electric telescopic rod connected to the top of the cover plate. The top telescopic end of the electric telescopic rod is connected to a lifting plate. Several equally spaced connecting rods are connected to the bottom center of the lifting plate. The connecting rods are located inside the lifting channel. The connecting rods can drive the connecting plate to lift and adjust, thereby driving the fastener to be processed into the electrolyte, ensuring that the fastener and the electrolyte are in full contact.

[0011] Further defining the above technical solution, the end of the connecting rod away from the lifting plate is connected to a connecting plate, and four connecting knobs are threaded around the bottom of the connecting plate. By combining the connecting knobs, it is possible to achieve compatible clamping and fixing of fasteners of different lengths.

[0012] Further defining the above technical solution, the outer arc surface of the connecting knob is slidably connected to a backing member, the top of the backing member is in contact with a fastener, and the bottom of the connecting plate is provided with a limiting groove located directly above the backing member. The top of the fastener is in contact with the inner wall of the limiting groove. The top and bottom clamping and fixing method can minimize the combination of the fasteners in this device, and the blocking part is a non-stressed structure of the fastener.

[0013] Further defining the above technical solution, the portion of the conductive element located inside the housing is rectangular, and the width of the rectangular portion of the conductive element is greater than the width of the connecting plate. Using a rectangular conductive element can ensure that the ionization effect is uniform for fastener electroplating.

[0014] Further defining the above technical solution, the bottom of the cover plate is provided with a sealing element, which contacts and presses against the top of the housing. A sealing ring is provided at the joint where the water inlet pipe and the water outlet pipe are connected to the housing. The structure of the sealing ring can ensure that the electrolyte will not splash or cause other problems.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The electrolyte is fully utilized. This device can drive the electrolyte to circulate through the circulation component, thereby making the electrolyte evenly distributed inside the shell and improving the utilization rate of the electrolyte. 2. Uniform electroplating: The structure of the conductive components enables metal ions to be evenly distributed around the fasteners during the electroplating process, ensuring a uniform electroplating effect. 3. Reduce obstruction by clamping and fixing the top and bottom of the fastener to achieve a secure fastener fixation effect, thereby ensuring uniform electroplating on the outer arc side of the fastener.

[0019] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0020] Example 1: This example provides an electroplating apparatus for producing corrosion-resistant fastening screws, such as... Figures 1-3 As shown, it includes a housing 1, a circulation component 2 connected to the outer side of the housing 1, a cover plate 3 connected to the top of the housing 1, an electroplating component 4 connected to the top of the cover plate 3, a lifting component 6 connected to the top of the cover plate 3, and a vertically penetrating lifting channel 5 provided at the center of the cover plate 3.

[0021] The circulation component 2 includes a water pump 201 connected to the side of the housing 1. The water inlet end of the water pump 201 is connected to a water inlet pipe 202, which is connected to the bottom side of the housing 1. The other end of the water pump 201 is connected to a water outlet pipe 203, which is connected to the top side of the housing 1 away from the water inlet pipe 202. The water pump 201 drives the electrolyte to circulate, which can achieve uniform ion distribution inside the electrolyte and ensure full utilization of the electrolyte.

[0022] The electroplating component 4 includes an ionization generator 401 connected to the top of the cover plate 3. The ionization generator 401 is electrically connected to a conductive element 403. A conductive sensor 402 is connected to the side of the ionization generator 401. The conductive sensor 402 is electrically connected to the conductive element 403. The bottom of the conductive element 403 extends into the housing 1. The conductive element 403 enables the ionization generator 401 to fully contact the electrolyte, ensuring the stability of the electroplating process of this device.

[0023] The lifting component 6 includes an electric telescopic rod 601 connected to the top of the cover plate 3. The top telescopic end of the electric telescopic rod 601 is connected to a lifting plate 602. Several equally spaced connecting rods 603 are connected to the bottom center of the lifting plate 602. The connecting rods 603 are located inside the lifting channel 5.

[0024] The end of the connecting rod 603 away from the lifting plate 602 is connected to a connecting plate 604, and four connecting knobs 605 are threaded around the bottom of the connecting plate 604.

[0025] The outer arc surface of the connecting knob 605 is slidably connected to the abutment 606, the top of the abutment 606 is in contact with the fastener 608, and the bottom of the connecting plate 604 is provided with a limiting groove 607 located directly above the abutment 606, and the top of the fastener 608 is in contact with the inner wall of the limiting groove 607.

[0026] The specific working principle is as follows: This device can effectively improve the stability of uniform electroplating on the outer arc surface of fastener 608. Compared with traditional devices, this device can fix fastener 608 more accurately, thus only blocking the top and bottom of fastener 608, ensuring that the main force-bearing outer arc surface thread structure is not blocked, thereby achieving a uniform and accurate electroplating effect on the outer arc surface thread structure.

[0027] Example 2: This example provides an electroplating apparatus for producing corrosion-resistant fastening screws, such as... Figures 1-3 As shown, the portion of the conductive component 403 located inside the housing 1 is rectangular. The width of the rectangular portion of the conductive component 403 is greater than the width of the connecting plate 604. A sealing element is provided at the bottom of the cover plate 3. The sealing element contacts and presses against the top of the housing 1. A sealing ring is provided at the joint where the water inlet pipe 202 and the water outlet pipe 203 penetrate and connect to the housing 1.

[0028] The specific working principle is as follows: This device can achieve the effect of uniform and complete electroplating of fastener 608. When this device is used, the fastener 608 to be processed is placed inside the limiting groove 607. At this time, the connecting knob 605 is rotated to move the abutment 606 upward. Thus, the combination of the abutment 606 and the limiting groove 607 achieves the effect of neatly fixing the fastener 608.

[0029] The device then turns on the water pump 201 and adds electrolyte into the housing 1 to achieve the effect of electrolyte circulation. Then, the ionization generator 401 is turned on and contacts the electrolyte through the conductive part 403 to measure the conductivity of the electrolyte. At this time, the electric telescopic rod 601 drives the lifting plate 602 to descend, thereby immersing the fastener 608 in the electrolyte.

[0030] The electroplating effect of electrolyte on the outer surface of fastener 608 is achieved by ionization generator 401. At the same time, as the electroplating progresses, the conductivity sensor 402 displays a change in conductivity index as the electrolyte is used. As conductivity decreases, the electrolyte is replaced after a period of time.

[0031] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
