As shown in FIG.

On the upper side of the transfer frame 11 is formed a drive cutout portion 11a into which a drive chain 12e having a drive protrusion 12ee of the drive portion 12 is inserted to have a predetermined length as shown in FIG. The hanger support cutout part 11b is formed in the lower side of the frame 11 so that the support hanger 13g of the hanger support feed part 13 may be supported over the full length of the conveyance frame 11.

The driving unit 12 is a bracket 12a installed at a predetermined height from the ground, the motor 12b installed on one side of the bracket 12a, and the bracket 12a, and installed in the rotational force of the motor 12b. The reducer 12c to decelerate, the sprocket 12d connected to the reducer 12c, and the sprocket 12d are wound around the sprocket 12d and rotated together with the sprocket 12d, and a plurality of driving protrusions 12ee are provided at one side. It consists of the drive chain 12e provided. The driving protrusion 12ee is inserted into the groove of the driven chain 13c to be described later so that the driven chain 13c is moved by the rotational force of the motor 12b.

The hanger support conveying part 13 is to support the plated object 200 is transported, as shown in Figure 8, the roller (13a) accommodated in the interior of the transport frame 11, and shown in FIG. As shown in FIG. 7, the roller support shaft 13b for connecting the roller 13a and the roller support shaft 13b for connecting the roller 13a and the groove into which the driving protrusion 12ee of the drive chain 12e is inserted are supported. An intermittently formed driven chain 13c, a connecting plate 13d which is preferably bolted to the driven chain 13c, and a bolt on one side of the connecting plate 13d, preferably as shown in FIG. Hanger frame 13e to be fixed and a connection terminal 13f which is preferably bolted to one side of the hanger frame 13e and electrically connected in surface contact with a female connection terminal 71 installed in the plating part 70. And, one side of the hanger frame (13e) is preferably bolted and folded Terminal (13f) and electrically connected to the support consists of a hanger (13g) for flowing a taker 200 is also plated when the current blood.

The immersion degreasing unit 20 is used to remove contaminants such as organic matter attached to the surface of the plated object 200 transferred from the plated object transfer unit 10. Remove contaminants by action and electrical action. Specifically, the immersion degreasing unit 20 is a step 1 to remove the foreign material by dipping the plated material 200 in the degreasing tank, and 2 to remove the foreign material by applying electricity to the plated material 200 transferred through this first step. Divided into stages. The second step may be selectively used in a cathode degreasing step of removing contaminants by hydrogen gas generated from a metal surface or an anode degreasing step of passing electricity through the plated material 200 as an anode. In the case where the plated object 200 is carbon steel, it is preferable to immerse and degrease the water mixed with a solvent such as acetone, benzene, alcohol or ether.

The water washing part 30 is to wash the plated material 200 which has passed through the immersion degreasing part 20 with water, and the water washing part 30 is a pickling step to be described later as shown in FIG. 3 to an air knife step. It is desirable to be installed continuously in each process.

The water washing part 30 is provided with a plurality of water pipes 31 installed to be sprayed with water from the upper side of the plated object 200 to be transported, and is installed below the water pipes 31 and is shown in FIG. 10. As described above, preferably, the upper portion of the front view is configured to have an extended discharge portion 32 having a trapezoidal shape that is narrow and becomes wider toward the lower side. When the expansion discharge part 32 has the above-described shape, since the amount of the washing water that is in contact with the plated is increased relative to the flow rate supplied in the same manner, the washing efficiency is improved.

The pickling unit 40 removes the scale of the plated material 200 passed through the electrolytic degreasing unit and the water washing unit 30. The pickling tank is preferably filled with washing water such as hydrochloric acid. The pickling part 40 serves to remove the acid remaining in the plated material 200 before entering the plating process so that adverse effects are not applied to the plated material 200. On the other hand, in the pickling bath, metal salts or metal ions that accumulate in the plating other than the acid are accumulated. This shortens the life of acid and flushing water, so it is advisable to replace it periodically or periodically while observing its turbidity.

The ultrasonic electrolytic degreasing unit 50 generates ultrasonic waves by applying electricity to the vibrator to remove contaminants on the surface of the plated material 200 which has passed through the pickling unit 40 and the water washing unit 30, and at the same time, Electrode of the cathode is applied to the cathode 200 to generate hydrogen to electrolytically degrease the contaminants by pushing them out of the plated material 200.

The acid activator 60 is easy to be plated 200 while passing through the active tank overflowing the ultrasonic electrolytic degreasing unit 50 and the water washing unit 30 flowing weakly acidic treatment solution. To be electroplated.

The plating part 70 is preferably an acid zinc plating on the surface of the plated material 200 passed through the acid activator 60 and the water washing part 30. The plating bath containing the plating solution has a positive current. The current to be plated 200 that flows and is immersed in the plating bath flows through the cathode current before being immersed in the plating bath. Specifically, as shown in FIG. 11A, a female connection terminal 71 through which a negative current flows is fixed to the transfer frame 11 at an upper side of the plating bath, and as shown in FIG. 11C, the female connection terminal 71 is fixed to the transfer frame 11. The connecting terminal 13f of the hanger feeder 13 is inserted. The connection terminal 13f is brought into contact with the female connection terminal 71 so that a current flows. As a result, the current of the positive electrode flows to the plating bath, and the current of the negative electrode flows to the support hanger 13g through the connection terminal 13f, thereby plating by the electrical reaction. On the other hand, the lower side of the female connection terminal 71 is preferably bolted to the transfer frame 11 and prevents the wear powder generated due to the surface contact of the connection terminal 13f and the female connection terminal 71 falls into the plating bath. Pedestal 72 is provided over the entire length of the plating bath.

The chromate unit 80 is a process that is processed to prevent discoloration of the plated plated material 200 that has undergone the plating unit 70 and the water washing unit 30, to increase corrosion resistance, and to obtain a glossless plating surface. , The plated object 200 is immersed in a chromate bath.

The air knife unit 90 removes water and foreign matter from the plated object 200 that is subjected to the chromate unit 80 and the water washing unit 30, and may be replaced by an air knife using a known air. .

The drying unit 100 is to dry the plated to-be-sold 200 transferred from the air knife unit 90 in a closed space, and the drying temperature after chromate treatment greatly affects the corrosion resistance at around 60 ° C. It is preferable to dry. Corrosion resistance decreases above 70 ° C. Corrosion resistance deteriorates badly and chromate effect decreases significantly at 80 ° C. This is because the chromate coating cracks when the drying temperature is 70 ° C or higher.

Reference numeral "300" not described above indicates the oil / water separator 300, and is installed between the deposition degreasing unit 20 and the pickling unit 40 and the plating unit 70 as shown in FIG. 2.

The plated object 200, which has undergone the drying part 100, is transferred to the first position because the plated object conveying part 10 transfers the object to be plated 200 while forming a cycle. The plated to-be-plated object 200 is separated and inspected and then finished by packaging.

As the present invention can be variously modified by those skilled in the art without departing from the scope of the claims, the technical protection scope of the present invention is not limited to the specific preferred embodiments described above. Do not.
