Description

Plating rack

The invention relates to the technical field related to electroplating fixtures, in particular to a plating rack for facilitating the user to hang the electroplated workpiece.

Press, when the product is to be electroplated, the plated workpiece needs to be clamped on a plating rack, and then the plating rack and the plated workpiece are placed in a plating device for electroplating. For the structure of the conventional plating rack, refer to Patent No. I343422 of the Chinese Patent Publication. The conventional plating rack is provided with at least one positioning member on a hook, and each of the positioning members is provided with a clamping structure at one end.

In order to increase the versatility of the electric hanger, the positioning member of the plating hanger is further designed to have flexibility.

According to the above description, the conventional plating rack has a large processing error and the clamping structure on the positioning member is the clamping force by the deformation, but the respective clamping structure cannot be unified at all. Or exert an average force on the plating machine On the piece. Not only the clamping structure, but also the positioning parts of the conventional plating rack have the same problem. And this uneven force is directly reflected on the electroplated workpiece, causing the electroplated workpiece to be stressed and twisted. This distortion phenomenon is liable to cause cracking or poor color formation of the plating film due to twist adjustment of the finished product when it is used in the finished product after the plating film is formed.

In addition to the above-mentioned problems of the structure of the plating rack itself, it is easier to cause collision, drop, manual pulling, cleaning or load deformation during use. The phenomenon of the above deformation is increased, and the force for twisting the plated workpiece is also greater. Such uncontrollable factors increase the poor rate of plating.

In view of the above problems and deficiencies in the prior art, it is an object of the present invention to provide a plating rack, which can timely guide the deformation of the plated workpiece for a reason, maintain the best condition of the plated workpiece, and provide the plated workpiece to be disposed on When plating the rack and performing the plating work, it is necessary to avoid the distortion of the clamp force or the thermal deformation during the processing.

According to the above object of the present invention, a plating rack is provided, which comprises a precision processing machine on a metal plate member, integrally forming a frame body and a plurality of clamping portions, and each clamping portion is matched with each insertion on the plating workpiece. Place the film. Among them, the frame system matches the plating workpiece extension. The clamping portion extends outward from the frame body, and has a connecting portion integrally formed, two clamping arms, an insertion groove and a cutting groove. The insertion slot setting position of the plated workpiece is provided by the insertion groove, and the plated workpiece is returned to the preset state in time, and the thermal deformation during the plating process can be prevented, and the conventional fixture is removed. The structure of the clamping prevents the clamping force from twisting the missing parts such as the plating workpiece.

The position of each interposer 32 is set. Moreover, the frame body 1 and each of the clamping portions 2 are integrally formed on the metal plate member through a precision processing machine (for example, a CNC, a laser cutting machine, a computer punch, etc.). In the implementation, the plating rack 100 of the present invention can be further locked on a hanger 4, and the inserting piece 32 for providing the plating work 3 is inserted and fixed corresponding to each clamping portion 2, and is conveniently placed by the hanger 4 to be placed in the plating. In the pool.

The frame 1 is matched with a sheet-like body extending from the plated workpiece 3, and has at least one keyhole 12 and a support portion 14 and a plurality of hollow regions 16. The keyhole 12 The through-frame body 1 is formed to extend and cooperate with the locking component to extend the hanger 4 and the frame body 1. The support portion 14 is defined by at least one of the fins 141 erected on the frame body 1 to match the support requirement of the plated workpiece 3; in addition, the support portion 14 can additionally increase the rigidity of the frame body 1 to avoid deformation of the frame body 1. . Each of the hollow regions 16 is formed through the frame body 1 (ie, the thickness direction of the sheet) to prevent the frame body 1 from interfering with the flow of the plating solution. In practice, the keyhole 12 and the support portion 14 can be selectively omitted as needed. In order to prevent the frame 1 from reacting with the plating material in the plating bath, a surface of the frame 1 may be further coated with an insulating coating 18 (as shown in Figures 2 and 7).

The clamping portion 2 extends outward from the frame body 1 (as shown in FIG. 3), and has a connecting portion 21 integrally formed, two clamping arms 22, 23, an insertion groove 24, a slot 25 and two Arms 26, 27.
