Abstract

(57) [Summary] [Purpose] The present invention aims to uniformly coat a work in a barrel. [Structure] Inclined walls 14 are provided on both sides of an inner wall of a barrel 1, and when the barrel 1 is rotated, the inclined wall 14 causes a work W to be laterally agitated and stirred.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a barrel used when performing a plating process.

[0002]

[Prior art]

 As shown in FIG. 4, this type of barrel (1) has a regular polygonal shape of hexagon or more and has both side plates (2,2) having an axial hole (3,3) in the center and a large number of holes (5). It consists of the peripheral body (4), the upper opening (6) is covered with the lid (7), and the lock rods (8, 8) are rotatably attached to the upper surface of the lid (7). The rods (8, 8) are adapted to be engaged with the lock holes (9, 9) on the front and rear side edges of the opening (6).

In the barrel (1), the lid (7) is unlocked and the lid (7) is opened, and a work W such as a bolt, a nut and a washer is put into the lid (7) through the opening (6). After closing and locking it, as shown in Fig. 5, it was supported by the support rod (10) and immersed in the plating solution (11) in the plating tank, and the electrode (12) was passed through one shaft hole (3). ) Is inserted into the barrel (1), and the barrel (1) is rotated in the direction of arrow A as shown in FIG. 6 to perform plating treatment. At this time, the work W in the barrel (1) is agitated in the front-rear direction as shown by the arrow B as the barrel (1) rotates.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional barrel, as described above, the work W is overmixed and stirred only in the front-rear direction, and there is no overmixing stirring in the left-right direction. As shown in the appendix of Fig. 5, the current density ρ in the barrel is highest at the insertion position of the electrode (12), and becomes lower as it goes to the left and right. Therefore, the work W existing in the vicinity of the electrode insertion position is thickly plated, and the work W is lightly plated toward the left and right. Therefore, the work W in the barrel should not be uniformly plated. become.

[0005]

[Means for Solving the Problems]

 As a means for solving the above-mentioned conventional problems, the present invention consists of both side plates (2) and a perforated cylinder (4) having a polygonal cross section, and an opening (6) provided on one side is covered with a lid (7). It provides a worn barrel (1) with a slanted wall (14) inside.

[0006]

[Action]

 The work W in the barrel (1) is stirred in the front-rear direction by the rotation of the barrel (1) having the peripheral body part (4) having a polygonal cross section, and at the same time, it is also covered in the left-right direction by the inner inclined wall (14). Be stirred.

[0007]

【Example】

 The present invention will be described with reference to an embodiment shown in FIGS. 1 to 3. As shown in FIG. 4, the barrel (1) has a hexagonal shape and both side plates (2, 2) having a shaft hole (3, 3) in the center. 2) and a peripheral body (4) having a large number of holes (5), a lid (7) is attached to the opening (6) provided on one side, and the lid (7) is a lock rod (8, It is designed to be locked by the engagement of 8) with the lock holes (9, 9), and a gear (13) is attached to the outside of one side plate (2) as shown in FIG. Inside the barrel (1), a pair of left and right inclined walls (14, 14) are provided on both sides of the opening (6), and a large number of holes (15) are provided in each of the inclined walls (14, 14). Has been.

A work W is put into the barrel (1), the lid (7) is closed and locked, and the plating solution (11) in the plating tank is supported by the support rod (10) as shown in FIG. The electrode (12) is inserted into the barrel (1) through one shaft hole (3), and the gear (16) and gear (13) of the support rod (10) connected to the motor (not shown) are ) Rotate the barrel (1) via.

By the rotation of the barrel (1), the work W in the barrel (1) is stirred up and down in the front-back direction as shown by the arrow B in FIG. 6, but at the same time, as shown in FIG. , 14) also performs a lateral stirring motion indicated by arrow C. After plating, the barrel (1) is raised and the lid (7) is opened to transfer the work W in the barrel (1) to the inner basket of the centrifuge. At this time, the work W is opened ( Guided by the sloped walls (14) on both sides of 6), it smoothly falls through the opening (6).

In this embodiment, the inclined walls (14) are provided only on both sides of the opening (6) of the barrel (1), but the inclined walls (14) may be provided on the bottom surface or the side surface. However, if there are too many inclined walls (14), stirring will be intense and the work W will be scratched, so care must be taken.

[0011]

[Effect of device]

 Therefore, in the present invention, the work in the barrel is stir-moved back and forth and left and right, so that the plating is uniformly performed.
