Description

Technical Field

[0001] This utility model belongs to the technical field of round steel end face spraying equipment, specifically relating to a bidirectional swing-type round steel end face spraying device. Background Technology

[0002] Round steel is a solid steel material with a circular cross-section, widely used as a raw material in the production of seamless steel pipes and the manufacturing of mechanical parts. Sometimes, it is necessary to spray paint onto one end face of the round steel to enhance its corrosion resistance, distinguish its steel grade and production information, improve its recognizability, and enhance its appearance. Currently, most companies use manual spraying, where operators hold a spray gun to apply paint to one end face of the round steel. This method is relatively inefficient and produces unsatisfactory results, making it unsuitable for mass production. Although some large steel mills have adopted automatic spraying devices, these devices can only color the end face of round steel at a fixed height, not those at varying heights. Therefore, it is necessary to develop a device capable of spraying the end face of round steel at varying heights.

[0003] After searching, three patent documents were found to be most relevant to this utility model technology. The specific contents are described below:

Since the eight bearing segments 603 of the four fifth supports 6 located within the eight eighth through holes 705 of the four sixth supports 7 change position not only in the vertical direction but also in the left and right direction, the eight bearing segments 603 located within the eight eighth through holes 705 are all driven shafts. In contrast, since the other eight bearing segments 603 of the four fifth supports 6 located within the eight tenth through holes 905 of the four eighth supports 9 only change position in the vertical direction and do not change position in the left and right direction, the other eight bearing segments 603 located within the eight tenth through holes 905 are all driving shafts, and can be set to 0.

[0072] like Figure 1 As shown, assuming that initially all eight eighth protrusions 602 of the four fifth supports 6 are in an upright position, the simplified version is as follows: Figure 27 As shown, along the four drive shafts O, ① and ③ simultaneously rotate 90 degrees clockwise, and ② and ④ simultaneously rotate 90 degrees counterclockwise. Then, all eight eighth protrusions 602 of the four fifth supports 6 are horizontally positioned. Figure 4 As shown, the swing direction of the four fifth supports 6 can be defined as positive.

[0073] like Figure 4 As shown, assuming that initially all eight eighth protrusions 602 of the four fifth supports 6 are horizontally positioned, the simplified version is as follows: Figure 28 As shown, along the four drive shafts O, ① and ③ simultaneously rotate 90 degrees counterclockwise, and ② and ④ simultaneously rotate 90 degrees clockwise. Then, all eight eighth protrusions 602 of the four fifth supports 6 are vertically positioned. Figure 1 As shown, the swing direction of the four fifth supports 6 can be defined as opposite.

[0074] The working principle of the bidirectional swing-type round steel end face spraying device provided by this utility model

[0075] like Figure 1 As shown, when all eight eighth protrusions 602 of the four fifth supports 6 are vertically arranged, the spraying machine 11 is in its lowest working position, which corresponds to the lowest position of the round steel 17; as Figure 4 As shown, when all eight eighth protrusions 602 of the four fifth brackets 6 are horizontally arranged, the spraying machine 11 is in the highest working position, which corresponds to the highest position of the round steel 17.

[0076] In summary, the height of the round steel 17 should be between the lowest and highest positions. Since the four fifth supports 6 can continuously swing, the optimal position can always be found by adjusting the tilt angle of the four fifth supports 6 according to the height of the round steel 17. The optimal position refers to the position of the spraying machine 11 facing the left end face of the round steel 17.

[0077] In order to achieve precise swinging of the fifth support 6, four servo motors can be installed at one end of the four drive shafts. Since the encoder can detect the rotor's position, speed and acceleration in a timely manner and feed this information back to the servo driver, the servo motors can be precisely controlled. Therefore, by driving the four servo motors, the tilt angles of the four fifth supports 6 can be adjusted.

[0078] The present invention provides a method for using a bidirectional swing-type round steel end-face spraying device.

[0079] Assuming that initially all eight eighth protrusions 602 of the four fifth supports 6 are vertically positioned, firstly, the four connecting rods 12 are moved horizontally and uniformly to the left along the eight fifth through holes 404 of the two linear bearings 4 to prevent the spraying machine 11 from bumping into the round steel 17; then, the first support carriage is moved horizontally and uniformly so that the spraying machine 11 can be aligned with the left end face of the round steel 17 from the front and rear directions; according to the setting height of the round steel 17, the four fifth supports 6 are then simultaneously rotated in the forward direction at the same uniform speed at the same angle until the spraying machine 11... The thirteenth protrusion 1103 is aligned with the left end face of the round steel 17 so that the spraying machine 11 can be aligned with the left end face of the round steel 17 from the vertical direction; then, along the eight fifth through holes 404 of the two linear bearings 4, the four connecting rods 12 are moved horizontally and uniformly to the right so that the spraying machine 11 can maintain the optimal distance from the left end face of the round steel 17. Then, the spraying machine 11 is started, so that the pigment contained in the cavity of the spraying machine 11 will be sprayed onto the left end face of the round steel 17 through the multiple thirteenth through holes 1105.

[0080] Supplementary explanation: The bidirectional swing-type round steel end face spraying device provided by this utility model adopts a symmetrical structure design. According to the diameter specification, setting height and fixed length of the round steel, multiple specifications of this utility model device should be designed and manufactured to match it. The optimal distance refers to the distance between the spraying machine 11 and the left end face of the round steel 17, which is just able to fall on the left end face and just able to cover the entire left end face.

[0081] As can be seen from the embodiments, the bidirectional swing-type round steel end face spraying device provided by this utility model can achieve the purpose of spraying pigment on the end face of the round steel. This utility model device has the characteristics of low manufacturing cost, simple operation and good use effect.

[0082] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
