Description

Technical Field

[0001] The utility model relates to the technical field of wire production, in particular to a steel wire impregnation phosphating device. Background Art

[0002] Steel wire phosphating by immersion is to treat the wire rod by immersion in a solution containing phosphoric acid and phosphates, aiming to form a uniform and dense phosphate protective film (phosphating film) on the surface of the steel wire, which is convenient for the effective attachment of lubricants in the saponification process and reduces the risk of steel wire breakage in the subsequent drawing process. In the existing technology, phosphating by immersion generally adopts zinc salt phosphating at medium temperature (70±5℃), and the phosphating time is adjusted flexibly according to the diameter of the wire rod and the required thickness of the phosphating film. However, in the actual process, over-phosphating is easy to occur, that is, the phosphating film on the surface of the steel wire is too thick and will break during drawing. At the same time, when the steel wire is removed from the phosphating box, part of the phosphating agent will be brought out to the outside world, causing waste and environmental pollution.

[0021] The dephosphorization components 100 are provided in two groups, and the two groups of the dephosphorization components 100 are arranged front and back, and the mounting frames 1 in the two groups of the dephosphorization components 100 are connected by a connecting frame 5, and the two liquid removal rollers 3 in the two groups of the dephosphorization components 100 are respectively distributed up and down and left and right.

[0022] It should be noted that: the connecting frame 5 is installed on the inner box wall of the outlet of the phosphating box, and the steel wire is phosphated with the raw material phosphoric acid liquid of the phosphating box and then passes through the annular structure in the two groups of dephosphorization components 100. As the steel wire moves forward, the liquid removal roller 3 is driven to rotate. The rotating liquid removal roller 3 can scrape off the excessively thick phosphating film attached to the steel wire, so as to control the film thickness of the phosphating film on the steel wire. The two groups of dephosphorization components 100 are arranged front and back, and at the same time, the two liquid removal rollers 3 in the two groups of dephosphorization components 100 are respectively distributed up and down and left and right, so the phosphating film on the steel wire can be removed to a certain extent without dead angles.

[0023] In the embodiments of the present invention, please refer to Figure 2 The driving assembly 4 includes a rotating wheel 41, two rotating wheels 41 are provided, and the two rotating wheels 41 are respectively fixedly connected to the connecting ends of the two screws 2, and the two rotating wheels 41 are connected through a conveyor belt 42.

[0024] It should be noted that: turning on the driving motor 43 can drive the screw 2 connected thereto to rotate. Since the two screws 2 are connected through the rotating wheel 41 and the conveyor belt 42, the two screws 2 rotate synchronously. Since the two screws 2 are respectively provided with two thread sections with opposite thread directions, and the two liquid-removing rollers 3 are respectively provided on the upper thread sections and the lower thread sections of the two screws 2, the aperture of the circular structure formed by the concave parts 31 of the two liquid-removing rollers 3 can be reasonably adjusted, so as to scrape the phosphoric acid liquid on the surface of phosphated steel wires of different diameters.

[0025] The working principle of the steel wire impregnation phosphating equipment provided by the utility model is as follows:

[0026] The connecting frame 5 is installed on the inner box wall of the outlet of the phosphating box. The steel wire is phosphated by the raw material phosphoric acid liquid of the phosphating box and passes through the annular structure in the two groups of dephosphorization components 100. As the steel wire moves forward, the liquid-removing roller 3 is driven to rotate. The rotating liquid-removing roller 3 can scrape off the excessively thick phosphating film attached to the steel wire, so as to control the film thickness of the phosphating film on the steel wire. The two groups of dephosphorization components 100 are arranged front and back, and the two liquid-removing rollers 3 in the two groups of dephosphorization components 100 are respectively distributed up and down and left and right. Therefore, the phosphating film on the steel wire can be removed to a certain extent without dead angles, and the phosphoric acid liquid is prevented from dripping to the outside of the phosphating box as the steel wire moves forward, causing pollution or waste of the phosphoric acid liquid.

[0027] Turning on the driving motor 43 can drive the screw 2 connected thereto to rotate. Since the two screws 2 are connected through the rotating wheel 41 and the conveyor belt 42, the two screws 2 rotate synchronously. Since the two screws 2 are respectively provided with two thread sections with opposite thread directions, and the two liquid-removing rollers 3 are respectively provided on the upper thread section and the lower thread section of the two screws 2, the aperture of the circular structure formed by the concave parts 31 of the two liquid-removing rollers 3 can be reasonably adjusted, so as to scrape the phosphoric acid liquid on the surface of the phosphated steel wires of different diameters.
