Abstract

This utility model discloses a stainless steel electroplating fixture technical field, specifically a duplex stainless steel pipe anti-corrosion coating electroplating fixture. The utility model includes a support base with an adjustment mechanism in the middle. The adjustment mechanism includes a fixing groove in the middle of the support base, and a bidirectional lead screw is rotatably mounted inside the fixing groove. This utility model, by setting up a full electroplating mechanism, uses a three-jaw clamp to replace the traditional two-jaw clamping of the steel pipe. The three-jaw clamp, with its three evenly distributed jaws, can evenly distribute force to clamp and fix the steel pipe. Simultaneously, the jaws are made of wear-resistant material, facilitating long-term use and reducing wear, significantly lowering maintenance costs.

The adjustment mechanism also allows for adjustment of the distance between the two sets of three-jaw clamps, facilitating clamping and limiting of steel pipes of different lengths.

Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel electroplating fixtures, specifically a duplex stainless steel pipe anti-corrosion coating electroplating fixture. Background Technology

[0002] Duplex stainless steel pipe is a type of steel pipe composed of two phases: ferrite and austenite. In order to ensure the wear resistance and hardness of duplex stainless steel pipe, a dense protective film is formed on its surface through electroplating during the steel pipe production process, which can effectively isolate the steel pipe from corrosive media.

[0003] In existing duplex stainless steel pipe electroplating, the stainless steel pipe is immersed in an electroplating bath for electroplating treatment. To ensure stability during electroplating, a clamp is used to fix it. However, the part of the stainless steel pipe that is clamped by the clamp cannot come into contact with the electrolyte inside the electroplating bath. This results in the anti-corrosion coating not being electroplated on this part, leading to incomplete electroplating of the stainless steel pipe as a whole and affecting the final electroplating effect. Utility Model Content

[0004] The purpose of this invention is to provide a jig for electroplating anti-corrosion coating on duplex stainless steel pipes to solve the problems in the prior art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A duplex stainless steel pipe anti-corrosion coating electroplating fixture includes a support base, and an adjustment mechanism is provided in the middle of the support base.

[0007] The adjustment mechanism includes a fixed groove in the middle of the support base, a bidirectional lead screw is rotatably installed inside the fixed groove, a motor is connected to the right end of the bidirectional lead screw, and moving blocks are symmetrically threaded on the left and right sides of the outside of the bidirectional lead screw, and the moving blocks are slidably connected to the fixed groove.

[0008] Preferably, a support block is fixedly installed at the upper middle part of the support base, and a trapezoidal groove is opened on the upper inner side of the support block. The steel pipe body is placed inside the trapezoidal groove opened on the upper inner side of the support block.

[0009] Preferably, the steel pipe body is provided with a full electroplating mechanism on the left and right sides of its exterior, and the full electroplating mechanism is located at the upper end of the moving block.

[0010] Preferably, the full electroplating mechanism includes a fixed block fixedly installed on the upper end of the movable block, a T-shaped groove is formed at an equal angle on the inner end of the fixed block, a T-shaped clamping claw is slidably arranged inside the T-shaped groove, and a rubber plate is installed on the inner end of the T-shaped clamping claw.

[0011] Preferably, a connecting block is connected to the outer side of the T-shaped gripper, the connecting block is slidably disposed inside the sliding groove, the sliding groove is opened at an equal angle inside the rotating block, and a worm gear is fixedly installed at the outer end of the rotating block, the rotating block and the worm gear are rotatably disposed inside the fixed block.

[0012] Preferably, a worm is meshed with the lower side of the worm gear, and a motor is connected to the rear end of the worm.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model, by setting up a comprehensive electroplating mechanism, uses a three-jaw clamp to replace the traditional two-jaw clamping of the steel pipe. The three-jaw clamp, with its three evenly distributed jaws, can apply force evenly to clamp and fix the steel pipe, strengthening the fixation of the steel pipe. At the same time, the three-jaw clamp can fix both ends of the steel pipe. Specifically, one end of the steel pipe can be clamped and fixed first, and its center position after being lifted can be aligned with the center position of the clamp at the other end. After the steel pipe is electroplated in the electroplating tank, the clamp at the other end of the steel pipe can clamp and fix the other end of the steel pipe. Conversely, the clamp at the other end can be released from the steel pipe, and then the steel pipe can be electroplated again. The part of the clamp at the other end that is in contact with the steel pipe will come into contact with the electroplating solution inside the electroplating tank. This setting allows the steel pipe to be electroplated comprehensively.

[0015] 2. This utility model, by setting an adjustment mechanism, has three-jaw clamps set on the upper left and right sides of the support base, in two sets, which can clamp and limit the left and right ends of the stainless steel pipe to be electroplated. The distance between the two sets of three-jaw clamps can be adjusted, so that the three-jaw clamps can clamp and limit steel pipes of different lengths. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] To address the problems existing in the prior art, this embodiment provides the following technical solution: a dual-phase stainless steel pipe anti-corrosion coating electroplating fixture, comprising a support base 1, with symmetrically arranged full-area electroplating mechanisms 4 on the upper left and right sides of the support base 1. The steel pipe body 3 to be electroplated can be placed inside the upper part of the support block 2 installed at the middle upper end of the support base 1. The full-area electroplating mechanisms 4 are set at the upper end of the adjustment mechanism 5, which is located in the middle of the support base 1. The adjustment mechanism 5 can adjust the distance between the full-area electroplating mechanisms 4 according to the length of the steel pipe body 3, so that they can be moved to the left and right sides of the outer end of the steel pipe body 3. Then, the full-area electroplating mechanisms 4 can limit the left and right ends of the outer side of the steel pipe body 3, ensuring that the steel pipe body 3 can be fully electroplated.

[0026] like Figures 1-5 As shown, a support base 1 is provided, an adjustment mechanism 5 is provided in the middle of the support base 1, and a full electroplating mechanism 4 is symmetrically provided on the left and right sides of the upper end of the adjustment mechanism 5. The middle of the full electroplating mechanism 4 is opened into a cavity. In addition, a support block 2 is fixedly installed at the upper end of the middle of the support base 1. A trapezoidal groove is opened on the upper side of the inside of the support block 2, so that the steel pipe body 3 to be electroplated can be placed into the trapezoidal groove opened on the upper side of the inside of the support block 2.

[0027] The adjusting mechanism 5 includes a fixed groove 51 opened in the middle of the support base 1. A bidirectional lead screw 52 is rotatably arranged inside the fixed groove 51. A motor 53 is connected to the right end of the bidirectional lead screw 52. Moving blocks 54 are symmetrically threaded on the left and right sides of the outside of the bidirectional lead screw 52. The moving blocks 54 are slidably connected to the fixed groove 51.

[0028] After the steel pipe body 3 is fixed, the second motor 53 can be turned on. The second motor 53 can make the connected bidirectional lead screw 52 rotate inside the fixed groove 51. When the bidirectional lead screw 52 rotates, the moving blocks 54 connected by the left and right symmetrical threads on the outside will move in opposite directions. The distance between the left and right moving blocks 54 can be adjusted according to the length of the steel pipe body 3. The full electroplating mechanism 4 installed on the upper side of the moving block 54 will move synchronously with the moving block 54. The full electroplating mechanism 4 can be adjusted and moved to the left and right ends of the outside of the steel pipe body 3.

[0029] The electroplating mechanism 4 includes a fixed block 41 fixedly installed on the upper end of the movable block 54. The inner end of the fixed block 41 is provided with a T-shaped groove 42 at equal angles. A T-shaped clamping claw 43 is slidably arranged inside the T-shaped groove 42. A rubber plate 44 is installed on the inner end of the T-shaped clamping claw 43. At the same time, a connecting block 45 is rotatably connected to the outer side of the T-shaped clamping claw 43. The connecting block 45 is slidably arranged inside the sliding groove 46. The sliding groove 46 is opened at equal angles inside the rotating block 47. A worm gear 48 is fixedly installed on the outer end of the rotating block 47. The rotating block 47 and the worm gear 48 are rotatably arranged inside the fixed block 41. A worm 49 is meshed with the lower side of the worm gear 48. A motor 411 is connected to the rear end of the worm gear 49.

[0030] After the electroplating mechanism 4 is moved to the left and right ends of the steel pipe body 3, the motor 411 set on the left side of the electroplating mechanism 4 can be turned on. The motor 411 can make the connected worm 49 rotate. When the worm 49 rotates, it will drive the upper meshing worm wheel 48 to rotate. When the worm wheel 48 rotates, the rotating block 47 installed on the inner side will also rotate together. In addition, the tooth block on the outer side of the worm wheel 48 only occupies one-third of the outer position of the worm wheel 48, which can effectively control the rotation range of the worm wheel 48 and the worm 49.

[0031] The rotating block 47 rotates synchronously with the sliding groove 46 opened on its inner side. When the rotating block 47 rotates clockwise, the sliding connecting block 45 inside the sliding groove 46 will slide inward inside the sliding groove 46, which will drive the T-shaped clamping claw 43 connected to the inner side to move inward inside the T-shaped groove 42 opened on the inner side of the fixing block 41. The T-shaped clamping claw 43 will slide inward synchronously from three directions. At this time, the rubber plate 44 installed on the inner side of the T-shaped clamping claw 43 will fit against the outer wall of the steel pipe body 3. The T-shaped clamping claw 43 can clamp and fix the left end of the steel pipe body 3. In addition, the rubber plate 44 is made of wear-resistant material, which is convenient for long-term use and not easy to wear.

[0032] When the steel pipe body 3 is placed inside the support block 2, its central axis is lower than the center of the electroplating mechanism 4 on both sides. Simultaneously, one side of the outer wall of the steel pipe body 3 is in contact with the support block 2. After the T-shaped clamping claw 43 clamps and fixes the left end of the steel pipe body 3, the lower clamping claw of the T-shaped clamping claw 43 can push the steel pipe body 3 upwards. Finally, the T-shaped clamping claw 43 can lift the clamped steel pipe body 3, causing the outer wall of the steel pipe body 3 to detach from the support block 2. At the same time, the central axis of the steel pipe body 3 can be aligned with the mechanism 4 on the right side. In the middle of the full electroplating mechanism 4, the steel pipe body 3 is fixed inside the electroplating tank and can be electroplated inside the electroplating tank. After the electroplating is completed, the motor 411 set in the right full electroplating mechanism 4 is started, which can make the full electroplating mechanism 4 clamp and fix the right end of the steel pipe body 3. Conversely, the left full electroplating mechanism 4 loosens its clamping and fixing of the steel pipe body 3. At this time, the electrolyte inside the electroplating tank soaks the steel pipe body 3 again and can contact the part of the left full electroplating mechanism 4 that is loosened from clamping the steel pipe body 3. This setting can fully electroplat the steel pipe body 3.

[0033] In addition, when the steel pipe body 3 is electroplated, the full electroplating mechanism 4 needs to conduct electricity. The steel pipe body 3, as the cathode, needs to be connected to the negative terminal of the power supply. The full electroplating mechanism 4 can effectively conduct current through conduction, which can ensure that the ions in the electrolyte undergo a reduction reaction on the cathode surface of the steel pipe body 3 and form a coating.

[0034] Meanwhile, the fixture is installed upside down inside the upper side of the electroplating tank. During electroplating, the steel pipe body 3 and the full electroplating mechanism 4 are located inside the electroplating tank and in contact with the electrolyte inside the electroplating tank. The motor and lead screw installed in the fixture do not come into contact with the electrolyte. This arrangement can protect the motor and other components.

[0035] After the steel pipe body 3 is electroplated, the motor 411 on the right side of the electroplating mechanism 4 can be opened. The motor 411 is a forward and reverse motor, which can drive the worm gear 49 to drive the worm wheel 48 and the rotating block 47 to rotate counterclockwise. At this time, the T-shaped clamping claw 43 and the rubber plate 44 will move outward, and the rubber plate 44 will separate from the right end of the attached steel pipe body 3. At this time, the electroplated steel pipe body 3 can be removed.

[0036] The motor model mentioned above is Z4-180-21.

[0037] The working principle of this duplex stainless steel pipe anti-corrosion coating electroplating fixture is as follows: The steel pipe body 3 to be electroplated is first placed inside the upper side of the support block 2 installed at the middle upper end of the support base 1. The full electroplating mechanism 4 is symmetrically arranged on the left and right sides above the support base 1. The full electroplating mechanism 4 is installed at the upper end of the adjustment mechanism 5 and is set as two sets. After the steel pipe body 3 is placed inside the upper part of the support block 2, the position between the full electroplating mechanisms 4 can be adjusted through the adjustment mechanism 5 so that it can be adjusted according to the length of different steel pipe bodies 3, and adjusted to the left and right ends of the steel pipe body 3.

[0038] After the position of the full electroplating mechanism 4 is adjusted, open one side of the full electroplating mechanism 4 first. The full electroplating mechanism 4 can limit one side of the steel pipe body 3. At this time, the steel pipe body 3 can be lifted so that its center position is aligned with the center position of the other end of the full electroplating mechanism 4 and it is separated from the support block 2. Then, electroplating is performed on the steel pipe body 3. After the steel pipe body 3 is electroplated, open the other side of the full electroplating mechanism 4 to clamp and fix the other end of the steel pipe body 3. Conversely, loosen the clamping of the other end on the steel pipe body 3 and then electroplat the steel pipe body 3. This can ensure that the steel pipe body 3 is fully electroplated.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
