Description

Technical Field

[0001] The utility model relates to the field of surface passivation of galvanized angle irons, in particular to a device for surface passivation of galvanized angle irons. Background Art

[0002] Angle iron, commonly known as angle steel, is a long strip of steel with two sides perpendicular to each other. It is divided into equal-leg angle steel and unequal-leg angle steel. The two sides of equal-leg angle steel are equal in width. Angle iron is exposed to the outside for a long time during use, so it needs to be passivated. Passivation refers to the process of oxidation of metal by strong oxidants or electrochemical methods to make the surface inactive, which is the process of passivation. It is a method of converting the metal surface into a state that is not easily oxidized and slowing down the corrosion rate of the metal. In addition, the phenomenon that the chemical activity of an active metal or alloy is greatly reduced and becomes a precious metal state is also called passivation.

[0003] At present, in the existing passivation treatment of angle iron, most of them are directly placed under the nozzle to spray the passivation liquid. This does not stabilize the angle iron and is not convenient to rotate it. This easily leads to uneven spraying of the passivation liquid, which affects the quality of the angle iron. Utility Model Content

[0006] A clamping mechanism is provided inside the passivation equipment body, and the clamping mechanism includes a fixed plate, a mounting plate, a first V-shaped plate, a second V-shaped plate and an angle iron. The ends of the fixed shaft and the rotating shaft close to each other are fixedly connected with a fixed plate, two mounting plates are fixedly installed on the sides of the two fixed plates close to each other, and the first V-shaped plates are fixedly installed on the sides of the four mounting plates close to each other. An angle iron is provided on the tops of the two first V-shaped plates, and the second V-shaped plates connected to the angle iron are slidably connected on the sides of the four mounting plates close to each other, and two limit rods are fixedly installed on the bottoms of the two second V-shaped plates.

[0007] In one example, a slide groove is provided on one side of the four mounting plates close to each other, and an electric push rod is fixedly installed on one side of the inner wall of the four slide grooves.

[0008] In one example, the output shafts of the four electric push rods are all fixedly mounted with a slider fixed to the second V-shaped plate.

[0009] In one example, limiting grooves are provided on both inner sides of the two first V-shaped plates, and the four limiting grooves match the limiting rods.

[0011] In one example, a nozzle is fixedly mounted on the outer ring of the shunt pipe, and a hose is provided on the outer ring of the shunt pipe that penetrates and extends outside the passivation device body.

[0021] like Figure 1 to Figure 3 As shown, the embodiment of the utility model proposes a surface passivation device for galvanized angle iron, comprising a passivation device body 1, a fixed shaft 6 is rotatably connected to one side of the inner wall of the passivation device body 1, a motor 17 is fixedly installed on one side of the passivation device body 1, and a rotating shaft 18 that penetrates and extends into the passivation device body 1 is fixedly installed on the output shaft of the motor 17;

[0022] A clamping mechanism is provided inside the passivation equipment body 1, and the clamping mechanism includes a fixed plate 7, a mounting plate 8, a first V-shaped plate 9, a second V-shaped plate 10 and an angle iron 11. The fixed shaft 6 and the rotating shaft 18 are fixedly connected to the fixed plate 7 at one end close to each other, and two mounting plates 8 are fixedly installed on the side where the two fixed plates 7 are close to each other. The first V-shaped plate 9 is fixedly installed on the side where the four mounting plates 8 are close to each other. An angle iron 11 is provided on the top of the two first V-shaped plates 9. The four mounting plates 8 are slidably connected to the second V-shaped plate 10 connected to the angle iron 11 on the side where the four mounting plates 8 are close to each other, and two limit rods 13 are fixedly installed on the bottom of the two second V-shaped plates 10.

[0023] Specifically, a slide groove 16 is provided on one side of the four mounting plates 8 that are close to each other, and an electric push rod 15 is fixedly installed on one side of the inner wall of the four slide grooves 16. The electric push rod 15 is fixed by the slide groove 16, and the electric push rod 15 drives the slider 14 to move.

[0024] Specifically, the output shafts of the four electric push rods 15 are all fixedly mounted with sliders 14 fixed to the second V-shaped plate 10 , and the sliders 14 move the second V-shaped plate 10 of the ground hole downward to clamp the diagonal iron 11 .

[0025] Specifically, the inner sides of the two first V-shaped plates 9 are provided with limiting grooves 12, and the four limiting grooves 12 match the limiting rods 13. The limiting grooves 12 are used to engage and limit the limiting rods 13, so that the second V-shaped plate 10 is limited when the angle iron 11 is clamped.

[0026] Specifically, two connecting plates 5 are fixedly installed on the top inner wall of the passivation equipment body 1, and the two connecting plates 5 are fixedly provided with a shunt pipe 3 on one side close to each other.
