Technical Field
The utility model relates to the technical field of electroplating, and particularly discloses a movable anode chromium plating centralizing sleeve.
Background
Mobile anodic chrome plating is a type of chrome plating developed in recent years and is mainly used for deep hole inner hole chrome plating. Unlike conventional chrome plating, anodes used in mobile anode chrome plating are shorter than the pipe body of the workpiece to be chrome plated, and in the chrome plating process, the anodes need to move back and forth all the time.
The mobile chrome plating complete equipment comprises: short anode, upper and lower centralizing sleeve, conductive pull rod, upper and lower extension tube, movable anode reciprocating mechanism, chromium plating power supply, etc. In the design of a small-diameter inner hole mobile anode chrome plating tool, a centralizing sleeve is often designed to be an assembly with an anode. The main function of the centralizing sleeve is to keep the anode at the center of the long deep hole pipe, ensure that the chromium plating layer is uniform and not unilateral, and is one of important tools for moving anode chromium plating.
In order to ensure smooth movement of the anode during chromium plating of the deep hole inner tube, the centering sleeve and the deep hole inner tube are generally provided with gaps, and the gaps are generally controlled to be between 0.15 and 0.25mm according to the thickness of a plating layer.
As shown in fig. 1, both ends of the original righting sleeve are chamfered in order to smoothly move the anode in the deep hole inner tube. However, due to insufficient chamfering, when the centralizing sleeve moves to the upper and lower extension pipe joints, the centralizing sleeve is easy to cause the problems of clamping, accelerated abrasion, anode buckling, centralizing sleeve pull-down and the like due to the coaxiality difference of the extension pipe and the chromium plating pipe fitting.

Further, an acute angle formed between the guide inclined surface and the central axis of the cylindrical main body is alpha; wherein 15 ° < α <60 °.
The movable anode chromium plating centralizing sleeve is made of fluorine-containing engineering materials.

Examples
As shown in fig. 2 and 3, this embodiment discloses a movable anode chromium plating righting sleeve, which comprises a cylindrical main body 1 and a plurality of positioning convex strips 3 arranged on the outer surface of the cylindrical main body 1. In this embodiment, the number of the positioning convex strips 3 is four, the four positioning convex strips 3 are circumferentially uniformly arranged on the cylindrical main body 1, and a liquid passing channel 6 is formed between two adjacent positioning convex strips 3.
The positioning convex strip 3 extends along the length direction of the cylindrical body 1, and the central axis of the positioning convex strip is parallel to the central axis of the cylindrical body 1. The end of the cylindrical body 1 connected with the anode is provided with a jack 2, and the end of the anode is inserted into the jack 2.
As shown in fig. 2, the end surfaces of the two ends of the positioning protruding strip 3 incline from inside to outside to the middle of the positioning protruding strip 3 to form a guiding inclined plane 5. That is, the end surfaces of the two ends of the positioning convex strip 3 incline from one side close to the cylindrical main body 1 to the middle part of the other side of the positioning convex strip 3, so that the two ends of the positioning convex strip 3 respectively form a guiding inclined plane 5, and the whole movable anode chromium plating righting sleeve is shaped like a hammer. When the anode moves up and down in the deep hole pipe to be chromed, the two guide inclined planes 5 play a role in guiding, so that the problems of clamping, accelerated abrasion, anode buckling and pull-off of the centralizing sleeve when the centralizing sleeve moves to the joint of the upper extension pipe and the lower extension pipe are well solved.
Specifically, as shown in fig. 2, the acute angle formed between the guide slope 5 and the central axis of the cylindrical body 1 is α; wherein 15 ° < α <60 °. In this embodiment α is set to 15 °.
The positioning length should also be considered in the structural design of the centralizing sleeve, in principle, the longer the positioning length is, the better the centralizing positioning effect is; however, the longer the positioning length, the greater the hydraulic resistance. Therefore, through a comprehensive experiment combining the positioning precision and the liquid passing effect, the length L of the outer surface of the positioning convex strip 3 is set to be 35mm < L <45mm; the embodiment is set to 40mm, namely the positioning length is set to 40mm, so that the positioning effect is ensured, and meanwhile, the liquid passing effect is good.
In addition, the outer surface of the positioning convex strip 3 is an arc surface, so that the positioning convex strip 3 can be better matched with the inner wall of the deep hole pipe to be chromed.
In addition, be provided with the through-hole 4 that runs through it on the location sand grip 3, through-hole 4 and cross liquid passageway 6 can ensure the through-liquid level of righting the cover, prevent because of the exhaust is unsmooth, new chrome plating liquid is supplied renewedly untimely, causes plating current to diminish, perhaps causes defects such as chrome plating layer colour is not bright.
Most of the traditional centralizing sleeves are made of organic glass, nylon or polytetrafluoroethylene materials. The organic glass has good strength and wear resistance, but does not have lubricity, and under the condition of 0.15-0.25 gap, the centralizing sleeve and the inner wall of the deep hole pipe to be chromed are easy to be clamped, and often have a plurality of reciprocating cycles, so that the centralizing sleeve falls off or the anode is bent and deformed, and the engineering application purpose can not be achieved. The nylon material has similar performance and practical use effect to that of organic glass, and has poor use effect. The polytetrafluoroethylene material has good temperature resistance and lubricating performance, but has poor wear resistance and strength, the overall dimension is easy to obviously change when assembled with the anode, and the service life is not long.
As another implementation mode, the movable anode chromium plating righting sleeve of the embodiment adopts fluorine-containing engineering materials, such as PVDF polyvinylidene fluoride or perfluoroethylene propylene, and has certain lubricity, good strength, good wear resistance and long service life. Through experiments, the service life of the movable anode chromium plating centralizing sleeve is 3-5 times longer than that of a centralizing sleeve made of a common polytetrafluoroethylene material, and the cost is greatly reduced.
It should be noted that all of the features disclosed in this specification, or all of the steps in a method or process disclosed, may be combined in any combination, except mutually exclusive features and/or steps.
In addition, the foregoing detailed description is exemplary, and those skilled in the art, having the benefit of this disclosure, may devise various arrangements that, although not explicitly described herein, are within the scope of the present disclosure. It should be understood by those skilled in the art that the present description and drawings are illustrative and not limiting to the claims. The scope of the utility model is defined by the claims and their equivalents.
