Description

Technical Field

[0001] The invention relates to the field of drill bit electroplating, and in particular to a diamond drill bit electroplating device capable of circulating electroplating liquid. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to adhere a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance and enhancing aesthetics.

[0003] With reference to the comparative document, the publication number is CN114908402A. The present invention discloses an electroplating device for diamond drill bits, comprising an electroplating box, characterized in that a placement opening is provided on the top of the electroplating box, a placement rack which can move up and down is provided inside the placement opening, a plurality of through holes are provided on the inner surface of the placement rack, two telescopic cylinders are provided on the top of the electroplating box to push the servo motor in the mounting sleeve to move toward the side close to the placement rack, so that the rubber roller contacts the surface of the placement rack, and then the servo motor is used to drive the rubber roller to rotate, so that the placement rack can move downward inside the placement opening. Compared with the prior art of first lifting and then rotating, this structure can effectively improve the efficiency of placing diamond drill bits, and a plurality of through holes are provided inside the placement rack so that a plurality of diamond drill bits can be electroplated at one time, thereby further improving its production efficiency.

[0004] In the comparative document, although diamond drill bits can be electroplated, in the actual electroplating process, the plating solution can be slightly stirred to make the plating solution more uniform and faster when plating the drill bits. At the same time, when the plating solution is used to electroplate multiple drill bits, the plating solution will contain impurities, and the impurities will generally adhere to the bottom of the plating solution container. However, the comparative document lacks a cleaning and filtering device for the plating container, which results in impurities easily adhering to the diamond surface during electroplating, affecting the electroplating effect. At the same time, among the impurities attached to the filtered electroplating solution, there are more iron impurities, and iron impurities are very easy to form iron hydroxide colloid in the plating solution, which destroys the density and continuity of the coating, resulting in affecting the electroplating effect. However, due to the low density of the general filter, it is difficult to filter the hydrogen to purify the iron oxide colloid, which makes it impossible to effectively filter and purify the plating solution.

[0049] It should be noted that when the deceleration grinding wheel 303 contacts the bottom of the deceleration pressing rod 306 , the friction between the two will increase, thereby reducing the speed of the stirring transmission rod 302 .

[0050] Example 2

[0051] Reference Figure 3-6, support plates 2 are provided on both sides of the bottom of the electroplating tank 1, and support feet 201 are provided at the bottom of the support plates 2. A circulating suction pipe 501 is penetrated and connected to the bottom of the electroplating tank 1, and a suction water pump 502 is provided on the circulating suction pipe 501.

[0053] Further, the magnetic poles of the trigger magnetic block 402 and the drive magnetic block 510 are opposite.

[0054] It should be noted that when the triggering magnetic block 402 approaches the driving magnetic block 510 , the repulsive magnetic force can cause the filter plate 506 to shake left and right.

[0055] The working principle of the diamond drill bit electroplating device that can recycle the electroplating solution:

[0056] When electroplating the diamond drill bit, the operator can first insert the diamond drill bit to be electroplated into the drill bit placement hole 106. Since the drill bit is set larger at the top and smaller at the bottom before electroplating, when inserted into the drill bit placement hole 106, the upper end of the drill bit will be stuck in the drill bit placement hole 106 and will not leak out of the drill bit placement hole 106. After being inserted into the drill bit placement hole 106, the operator can press the movable plate 104 downward by moving the handle 105, so that the drill bit stuck in the drill bit placement hole 106 enters the electroplating cavity 109 through the placement through hole 108 for electroplating. When the movable plate 104 is pressed down, the movable plate 10 4, the contact rod 107 at the bottom moves downward together, so that the contact member 102 contacts and presses down the mounting plate 304, so that the deceleration pressing rod 306 at the bottom of the mounting plate 304 contacts the deceleration grinding wheel 303. At this time, the operator can turn on the starting motor 3 to make the starting motor 3 drive the stirring transmission rod 302 to rotate. Since the friction force will increase when the contact member 102 contacts the deceleration grinding wheel 303, the stirring transmission rod 302 drives the stirring rod 307 to rotate more slowly, so that the stirring rod 307 can stir the plating liquid in the plating chamber 109 at a slower speed, and at the same time, it can also avoid the impurities at the bottom being lifted up and attached to the surface of the drill bit due to the excessive rotation and stirring speed;

[0057] When the electroplating is completed, the operator can pull up the movable plate 104 by moving the handle 105 to take out the drill bit in the drill bit placement hole 106. When the movable plate 104 is pulled up, the contact piece 102 will be driven to move up through the contact rod 107 and disengage from the mounting plate 304. At this time, there is no pressure from the contact piece 102. Under the action of the elastic force of the elastic telescopic rod 305, the mounting plate 304 will drive the deceleration pressing rod 306 to move up and disengage from the deceleration grinding wheel 303. At this time, the stirring transmission rod 302 that drives the stirring rod 307 to rotate will resume the rotation speed and drive the stirring rod 307 to rotate at a faster speed. When the stirring rod 307 rotates at a faster speed, the impurities at the bottom of the electroplating chamber 109 will be cleaned through the cleaning bristles 308 at the bottom. While the stirring rod 307 rotates quickly to clean the bottom of the electroplating chamber 109 through the cleaning bristles 308, the stirring transmission rod 302 The moving rod 302 will drive the transmission turntable 403 to rotate rapidly. When the transmission turntable 403 rotates rapidly, the trigger magnet 402 will overcome the pulling force of the tension spring 401 through centrifugal force, and will be thrown out from the centrifugal chute 4 and approach the driving magnet 510 on the mounting plate 503. Since the mounting plate 503 and the driving magnet 510 have opposite magnetic poles, the filter plate 506 can be moved to the right through the repulsive magnetic force. At this time, the operator can turn on the suction pump 502, and the plating liquid in the plating chamber 109 is sucked into the filter box 5 through the circulating suction pipe 501. The filter plate 506 in the filter box 5 filters the impurities contained in the plating chamber 109. Since the transmission turntable 403 rotates continuously when the stirring transmission rod 302 rotates at a high speed, the filter plate 506 can be shaken through the repulsive magnetic force and the reset spring 507.

[0058] When the filter plate 506 shakes, the injection piston rod 509 will be shaken and sucked in the injection barrel 504 through the mounting plate 503. When the injection piston rod 509 is shaken and sucked in the injection barrel 504, the potassium permanganate in the liquid storage tank 505 will be sucked into the injection barrel 504 through the infusion tube, and sprayed into the filter box 5, and then sucked and circulated into the electroplating chamber 109 through the suction water pump 502, and the iron hydroxide colloid formed by the iron impurities will be chemically reacted to form manganese dioxide. When manganese dioxide is formed, it can be filtered by the filter plate 506, so as to achieve the effect of filtering and purifying the electroplating solution in the electroplating chamber 109.

[0059] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
