Description

Technical Field

[0001] This utility model belongs to the technical field of round steel end face spraying equipment, specifically relating to a round steel end face spraying device based on unidirectional side swing. 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:

[0053] The assembly process of the unidirectional side-swing round steel end face spraying device provided by this utility model is as follows:

[0054] Combination Figures 1 to 23As shown, firstly, the two first brackets 1 are arranged opposite each other. Then, the four tenth protrusions 802 of the seventh bracket 8 are simultaneously inserted between the two third protrusions 104 of the two first brackets 1. The four fourth screw holes 804 of the seventh bracket 8 and the four second through holes 107 of the two first brackets 1 are aligned. Then, the four bolts 11 are passed through the four second through holes 107 and screwed into the four fourth screw holes 804. In this way, the seventh bracket 8 and the two first brackets 1 can be assembled.

[0055] Then, four wheels 13 are inserted into the four first through slots 105 of the two first brackets 1, and the four axle holes of the four wheels 13 are aligned with the eight first through holes 106 of the two first brackets 1. Then, four axles 14 are installed in the four sets of aligned through holes. In this way, the two first brackets 1 and the four wheels 13 can be assembled into a first bracket vehicle.

[0056] Then, eight rolling bearings 12 are installed in the eight second grooves 604 of the four fifth brackets 6. Then, two fifth brackets 6 are inverted relative to each other. Then, the other two fifth brackets 6 are upright relative to each other. Then, eight bearing segments 703 of the two sixth brackets 7 are respectively inserted into the eight rolling bearings 12. In this way, the four fifth brackets 6, the eight rolling bearings 12 and the two sixth brackets 7 can be assembled.

[0057] Then, the two sixth bodies 601 of the two inverted fifth brackets 6 are simultaneously placed on the lower end face of one eighth body 801 of the seventh bracket 8, and the eight third screw holes 603 of the two fifth brackets 6 and the eight ninth through holes 803 of the seventh bracket 8 are aligned. Then, the eight bolts 11 are passed through the eight ninth through holes 803 and screwed into the eight third screw holes 603. In this way, the two inverted fifth brackets 6 and one seventh bracket 8 can be assembled.

[0058] Then, a fifth body 501 of the fourth bracket 5 is placed on the two lower end faces of the two sixth bodies 601 of the two upright fifth brackets 6, and the eight sixth through holes 503 of the fourth bracket 5 and the eight third screw holes 603 of the two fifth brackets 6 are aligned. Then, eight bolts 11 are passed through the eight sixth through holes 503 and screwed into the eight third screw holes 603. In this way, the fourth bracket 5 and the two upright fifth brackets 6 can be assembled.

[0059] Then, the eight sixth bosses 402 of the two linear bearings 4 are positioned opposite each other and respectively pass through the eight seventh through holes 504 of the fourth bracket 5.

[0063] The principle for setting the swing direction of the sixth bracket of the unidirectional side-swing round steel end face spraying device provided by this utility model

[0064] Combination Figure 1 and Figure 4As shown, for ease of description, let's define the sixth bracket 7 on the left as ① and the sixth bracket 7 on the right as ②; since the four bearing segments 703 located within the four eighth through holes 605 of the two inverted fifth brackets 6 do not change position, the four bearing segments 703 located within the four eighth through holes 605 are all considered as drive shafts, and can be set to 0.

[0065] like Figure 1 As shown, assuming that initially all four ninth protrusions 702 of the two sixth supports 7 are in an upright position, the simplified version is as follows: Figure 24 As shown, along the two drive shafts O, if ① and ② simultaneously rotate 90 degrees clockwise, then the four ninth protrusions 702 of the two sixth supports 7 will all be horizontally positioned. Figure 4 As shown, the swing direction of the two sixth supports 7 can be defined as positive.

[0066] like Figure 4 As shown, assuming that initially all four ninth protrusions 702 of the two sixth brackets 7 are horizontally positioned, the simplified version is as follows: Figure 25 As shown, along the two drive shafts O, if ① and ② simultaneously rotate 90 degrees counterclockwise, then the four ninth protrusions 702 of the two sixth supports 7 will all be vertically positioned, as shown. Figure 1 As shown, the swing direction of the two sixth supports 7 can be defined as opposite.

[0067] The working principle of the unidirectional side-swing round steel end face spraying device provided by this utility model

[0068] like Figure 1 As shown, when all four ninth protrusions 702 of the two sixth brackets 7 are vertically arranged, the spraying machine 9 is in its lowest working position, which corresponds to the lowest position of the round steel 15; as Figure 4 As shown, when the four ninth protrusions 702 of the two sixth brackets 7 are all horizontally arranged, the spraying machine 9 is in the highest working position, which corresponds to the highest position of the round steel 15.

[0069] In summary, the height of the round steel 15 should be between the lowest and highest positions. Since the two sixth supports 7 can continuously swing, the optimal position can always be found by adjusting the tilt angle of the two sixth supports 7 according to the height of the round steel 15. The optimal position refers to the position of the spraying machine 9 facing the left end face of the round steel 15.

[0070] In order to achieve precise swinging of the sixth bracket 7, two servo motors can be installed at one end of the two drive shafts. Since the encoder can detect information such as the position, speed and acceleration of the rotor in a timely manner and feed this information back to the servo driver in a timely manner, the servo motors can be precisely controlled. Therefore, by driving the two servo motors, the tilt angles of the two sixth brackets 7 can be adjusted.

[0071] The present invention provides a method for using a unidirectional side-swing round steel end-face spraying device.

[0072] Assuming that initially the four ninth protrusions 702 of the two sixth brackets 7 are all vertically positioned, firstly, the four connecting rods 10 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 9 from bumping into the round steel 15; then, the first bracket is moved horizontally and uniformly so that the spraying machine 9 can be aligned with the left end face of the round steel 15 from the front and rear directions; according to the setting height of the round steel 15, the two sixth brackets 7 are then simultaneously rotated in the forward direction at the same uniform speed at the same angle until the spraying machine... The twelfth protrusion 903 of the sprayer 9 is aligned with the left end face of the round steel 15 so that the sprayer 9 can be aligned with the left end face of the round steel 15 from the vertical direction; then, along the eight fifth through holes 404 of the two linear bearings 4, the four connecting rods 10 are moved horizontally and uniformly to the right so that the sprayer 9 can maintain the optimal distance from the left end face of the round steel 15. Then the sprayer 9 is started, so that the pigment contained in the cavity of the sprayer 9 will be sprayed onto the left end face of the round steel 15 through the multiple eleventh through holes 905.

[0073] Supplementary explanation: The unidirectional side-swing round steel end face spraying device provided by this utility model adopts a symmetrical structure design.
