Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, the method for manufacturing a hanger for furniture according to an embodiment of the present invention includes a pipe making step (S100), a plating step (S200), and a screen printing step (S300) .

The pipe making step S100 is a step of manufacturing the pipe 10 constituting the body of the hanger rod.

At this stage, the pipe 10 can be manufactured by welding an iron plate and welding both ends thereof, or by extruding aluminum.

The pipe 10 has two flat portions 11 formed on both sides thereof as shown in FIG. 2, an upper round portion 12 connecting upper ends of the two flat portions 11, and two flat portions 11 And a lower round portion 13 connecting the lower ends of the lower round portions 13 to each other. According to this structure, as shown in FIG. 3, when the hanger rods are installed on the closet 20, the sections are arranged in a vertically elongated elliptical shape so that the strength in the vertical direction can be improved.

The plating step S200 is a step of plating the surface of the pipe 10 and includes an acid deposition step S210, a first water washing step S220, a degreasing step S230, a second water washing step S240, (S250), a third washing step S260, a chromium plating step S270, a fourth washing step S280, and a plating drying step S290.

The acid deposition step S210 is an acid dipping treatment of the pipe 10 and includes a step of rusting the surface of the pipe 10 by immersing the pipe 10 in an aqueous solution containing a mixture of industrial detergent and sulfuric acid for a short time to be.

The first water washing step (S220) is a step of washing the acid-deposited pipe 10 with industrial water.

The degreasing step S230 is a step of electrolytically degreasing the washed pipe 10 to remove grease from the surface of the pipe 10.

In this step, anodic deaeration or cathodic degreasing, or both, may be selectively carried out.

The second water washing step S240 is a step of washing the degreased pipe 10 with industrial water.

The nickel plating step S250 is a step of nickel plating the cleaned pipe 10 and includes a woods nickel strike step S251, a first wattage nickel strike step S252, A watt nickel strike step (S253), and a bright nickel plating step (S254).

In the wood nickel strike step S251, the pipe 10 is plated with a woods bath of 120 to 240 g / l of nickel chloride and 62 to 125 ml / l of hydrochloric acid.

In the primary watt nickel strike step S252, the pipe 10 is plated with a watts bath of 220 to 370 g / l of nickel sulfate, 30 to 60 g / l of nickel chloride, 30 to 60 g / l of boric acid, In the secondary watt nickel strike step (S253), plating of the pipe 10 is carried out again with the same watts bath.

In the glossy nickel plating step S254, the pipe 10 is plated with a plating bath to which a brightening agent is added in a watt bath of 220 to 370 g / l of nickel sulfate, 30 to 60 g / l of nickel chloride and 30 to 60 g / l of boric acid do.

According to such a process, a thin nickel plating layer excellent in corrosion resistance can be obtained.

The third water washing step S260 is a step of washing the nickel-plated pipe 10 with industrial water.

The chrome plating step S270 is a step of chrome plating the cleaned pipe 10.

In this step, the pipe 10 is plated with a plating bath containing 200 to 300 g / l of chromic anhydride, 2 to 3 g / l of sulfuric acid and 1.5 to 3 g / l of tricalcium chloride.

The fourth water washing step S280 is a step of washing the chromium-plated pipe 10 with industrial water.

The plating drying step (S290) is a step of drying the washed pipe (10).

In this step, the plating on the pipe 10 is dried at room temperature.

The plating step S200 must be performed when the pipe 10 is made of an iron plate, and may be optionally performed when it is made of aluminum.

The screen printing step S300 is a step of forming the pattern 14 by screen printing on the surface of one of the two flat portions 11 of the pipe 10 or both of them, An ink manufacturing step S320, a screen printer setting step S330, a printing step S340, and an ink drying step S350.

The printing plate making step S310 is a step of producing a printing plate having the same shape as the pattern 14 to be printed on the pipe 10.

This step can be applied to a process of producing a known screen printing plate made of processes such as netting, film making, emulsion coating, exposure, development, and drying.

Meanwhile, the wire guide and the pattern 14 may be decorations of a certain pattern formed along the longitudinal direction of the pipe 10, and may have a shape added with a logo or the like as needed.

The ink manufacturing step (S320) is a step of producing an ink to be used for screen printing.

In this step, a two-component type thermosetting ink consisting of a main and a curing agent is mixed with a viscosity adjusting agent to prepare an ink for forming the pattern 14.

In this case, the viscosity adjusting agent to be mixed with the thermosetting ink is preferably 10 to 20% based on the weight of the thermosetting ink in consideration of the temperature and the humidity of the site.

The screen printer setting step (S330) is a step of adjusting the screen printer according to the standard of the pipe (10).

In this step, the stroke distance and angle of the squeegee, the ink application speed, the printing pressure, and the like are adjusted in the screen printing machine according to the standard of the pipe 10.

The printing step S340 is a step of fixing the pipe 10 to the screen printer and operating the printing machine to form the pattern 14 on the flat portion 11 of the pipe 10. [

The ink drying step (S350) is a step of drying the pattern (14) printed on the pipe (10).

In this step, the pipe 10 on which the pattern 14 is printed is put into a dryer and dried at a temperature of 130 to 150 DEG C for 25 to 30 minutes.

According to the method of manufacturing a hanger for furniture according to the present invention, the hanger rod for furniture having excellent strength and appearance is provided. In the process of manufacturing the hanger rod, a decorative pattern, Can be easily formed.
