The invention relates to a washing assembly in which a washing process is performed on a sheet metal used in the production of double-layered and copper-coated steel pipes.
In the present technique, copper coated double layer steel pipes are used as brake and fuel pipes in the automotive industry. During production, the steel sheet is forwarded in the forward direction, after the certain production phases, is subjected to pre-coating process using pre-coating chemical in the precoating container. The sheet metal coming out of the pre-coating container is covered with copper by electrolysis using a coating chemistry. Copper coated sheet metal is free from coating chemicals with water in the washing assembly. Then, the copper-coated steel sheet metals passing through certain production stages such as lacquering and drying are finally converted into double-layered pipes by the folding and joining methods known in the art. As an example of this method, applications of US20030041912 or JP11229084 for the known state of the art can be given. However, in the known technique, sheet metals can not be effectively cleaned from the chemicals on their surfaces before the lacquering process. This affects the quality of the lacquering process applied to the sheet metals after the washing process. B
The object of the invention is to improve the efficiency of the washing process applied for the removal of the chemicals in the surface after the copper coating of the sheet metals used in the production of copper-coated double layer steel pipe.
In order to achieve the said object, the invention is a washer device having at least one washing chamber extending from the inside through which at least one sheet metal is passed to be used for producing copper-coated double-layer steel pipe from inside. In the washing chamber of the washing assembly there is at least one pair of stripping devices. Thus, the free removal of the chemicals present in both sides of the sheet metal is provided.
In a possible embodiment of the invention, wiper pair comprises two holding members extending linearly opposite to each other and two wiping members located in the holding members. Thus, wiping members are provided to remove the surfaces of the sheet metal from the chemicals.
In another possible embodiment of the invention, the holding members have at least one channel which opens into the washing chamber and into which end part of the wiping members is located. Thus, a channel in which the wiping member is located is provided.
In another possible embodiment of the invention, the channel has a front part having a width through which a free end of the wiping member passes. Thereby, a rear part is provided which the wiping member can hold the channel.
In another possible embodiment of the invention, end part is in the form of a projection. Thus, when the sheet metal passes through the wiping members, the wiping member is placed at the rear part of the channel, preventing from coming out of the channel.
In another possible embodiment of the invention, the free end is in a form bent is closer to the sheet metal. Thus, during the movement of the sheet metal in the forward direction, it is ensured that the wiping member is in contact with the surfaces of the sheet metal longitudinally.
In another possible embodiment of the invention, the washing chamber has at least one front wall which supports a folding part of the wiping member. Thus, the bending portion of the wiping member is supported to enhance the efficiency of contact of the wiping members with the surfaces of the sheet metal.
In another possible embodiment of the invention, the wiping member is made from a flexible material. Thus, during the passage between the wiping members of sheet metal, the flexing of the wiping members is provided.
In another possible embodiment of the invention, the flexible material is a rubber material. Thus, a resilient material is provided for the wiping members during the passage of the sheet metal.
In another possible embodiment of the invention, the washing assembly is a washing assembly having the wiper pair comprising wiping members configured to contact at least one side of the sheet metal. Thus, removal of at least one surface of the sheet metal from chemicals is provided.
Referring to
The washing assembly (1) is surrounded by an outer wall (11) forming the outer periphery and has a rectangular shape similar to the periphery when viewed from above. At least one washing chamber (13) is provided on the inside of the washing assembly (1). The washing chamber (13) extends from the back of the washing assembly (1) and at least the sheet metal (4) passes through it. In the washing chamber (13) there is a washing liquid. In the preferred embodiment, said washing fluid is a demineralised water. On both sides of the washing chamber (13), there is at least one partition (12) which is situated opposite to each other. In a more detailed manner, the partitions (12) are positioned on both sides of the washing chamber (13) so as to be symmetrical about the axis of movement of the sheet metal (4). In a possible embodiment, each partition (12) is equal to each other. The partitions (12) are separated from each other by at least one inner wall (121) extending in a direction perpendicular to the forward direction (F) of the sheet metal (4).
The washing chamber (13) has at least one wiper pair (14). The wiper pair (14) comprises two holding members (15) extending linearly opposite to each other and two wiping members (17) located in the holding members (15). In a possible embodiment, an endpiece of the inner walls (121) extending into the washing chamber (13) is a holding member (15). In each holding member (15) there is at least one channel (151) which opens into the washing chamber (13). The channel (151) has a front part (152) having a width such that a free end (175) of the wiping member (17) can pass. A rear part (153) of the channel (151) is structured to be wider than the front part (152).
Referring to
During the movement of the sheet metal (4) in the forward direction (F), the surfaces of the sheet metal (4) are stripped together with the washing liquid as they pass through the gap between the wiper pair (14). In this way, the sheet metal (4) passing through the plurality of wiper pair (14) is stripped by the number of the wiper pair (14). In a case where the washing assembly (1) is cleaned or the wiping members (17) have to be replaced, the wiping members (17) are placed in the partitions (12). In the case where the sheet metal (4) is going through, the wiping members (17) are placed in tight contact into the channel (151) of the holding members (15) so that the washing assembly (1) is ready for washing.
In a possible embodiment, the wiping member (17) is produced from a flexible material, and in a more probable embodiment, from a rubber material.
