[0038] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] like Figures 1 to 10 As shown, a centering device for billet production includes: a conveyor roller conveyor 1, which includes a support and multiple rotating rollers rotatably connected to the support; two centering plates 2, which are arranged in parallel and form a centering channel between them; a swing arm 4, one end of which is hinged to the end face of the centering plate 2 away from the centering channel, and the other end of which is hinged to the support, with two parallel swing arms 4 corresponding to each centering plate 2, wherein the swing arm 4 corresponding to one centering plate 2 is arranged in parallel with the swing arm 4 corresponding to the other centering plate 2; and a driving assembly, which drives the multiple swing arms 4 to rotate synchronously through a connecting assembly.

[0040] A hinge plate 203 is fixed on the end face of the centering plate 2 away from the centering channel, and a hinge hole 205 is opened on the hinge plate 2 away from the centering plate 2; a hinge shaft 401 is fixed on one end of the swing arm 4, and a hinge tube 7 matching the hinge shaft 401 is fixed on the bracket, and the hinge shaft 401 is hinged to the inner side of the hinge tube 7; a hinge post 402 is fixed on the other end of the swing arm 4, and the hinge post 402 is hinged to the inner side of the hinge hole 205.

[0041] The connecting assembly includes a first L-shaped plate 5 and a second L-shaped plate 6. The first L-shaped plate 5 includes a first horizontal plate 501 and a first vertical plate 502 arranged perpendicularly to the first horizontal plate 501. The second L-shaped plate 6 includes a second horizontal plate 601 and a second vertical plate 602 arranged perpendicularly to the second horizontal plate 601.

[0042] The first horizontal plate 501, the second horizontal plate 601, the first vertical plate 502, and the second vertical plate 602 have the same length;

[0043] One of the centering plates 2 is provided with two first L-shaped plates 5. The first L-shaped plates 5 (where the horizontal and vertical plates connect) are fixedly connected to the hinge shaft 401. The first horizontal plate 501 of the first L-shaped plate 5 is set away from the centering plate 2. The first horizontal plates 501 of the two first L-shaped plates 5 are set in parallel.

[0044] Another centering plate 2 is provided with two second L-shaped plates 6. The second L-shaped plates 6 (at the connection between the horizontal and vertical plates) are fixedly connected to the hinge shaft 401. The second horizontal plates 601 of the second L-shaped plates 6 are set away from the centering plate 2, and the second horizontal plates 601 of the two second L-shaped plates 6 are set in parallel.

[0045] like Figure 10 As shown, it also includes two first connecting rods 10 and two second connecting rods 11, wherein one of the first connecting rods 10 is hinged at both ends to the first horizontal plate 501 of the two first L-shaped plates 5 respectively;

[0046] The other first connecting rod 10 is hinged at both ends to the second horizontal plate 601 of the two second L-shaped plates 6 respectively;

[0047] The first vertical plate 502 of the first L-shaped plate 5 and the second vertical plate 602 of the second L-shaped plate 6 on the same side are respectively hinged to the two ends of the second connecting rod 11.

[0048] Two first connecting rods 10 are set in parallel, and two second connecting rods 11 are set in parallel.

[0049] The driving component is a hydraulic cylinder 12. The housing of the hydraulic cylinder 12 is hinged to the bracket, and the output shaft of the hydraulic cylinder 12 is hinged to one end of the driving arm 1201. The other end of the driving arm 1201 is fixedly connected to one of the hinge shafts 401. By controlling the output length of the output shaft of the hydraulic cylinder 12, the spacing between the two centers can be driven, that is, the width of the centering channel can be adjusted.

[0050] The rotation of the hinge shaft 401 of one of the swing arms 4 can drive the other three hinge shafts 401 to rotate by the same angle through the first connecting rod and the second connecting rod 11, thus ensuring the synchronicity of the movements of the two centering plates 2.

[0051] The centering plate 2 is bent at both ends away from the centering channel to form guide parts 201. The guide parts 201 facilitate the entry of the steel billet into the centering channel. A pad 3 is fixed on the end face of the centering plate 2 near the centering channel. The pad 3 is detachably connected to the centering plate 2. After a period of use, if the pad 3 wears out, only the pad 3 needs to be replaced, without replacing the centering plate 2, thus reducing the service life of the device. The pad 3 is a structural component made of wear-resistant steel, which improves the service life of the pad 3.

[0052] The pad 3 is fixedly provided with a mounting seat 301 corresponding to the hinge plate 203 on the end face of the centering plate 2. The centering plate 2 has a mounting groove 204 corresponding to the mounting seat 301. The lower end of the mounting seat 301 has a positioning groove 302 corresponding to the centering plate 2. The mounting seat 301 is located inside the mounting groove 204, and the centering plate 2 is located inside the positioning groove 302. The positioning groove 302 and the mounting groove 204 position the mounting seat 301 of the pad 3, thereby improving the stability of the pad 3 during use.

[0053] The lower end of the mounting base 301 is fixed to two connecting plates 303. The hinge plate 203 is located inside the two connecting plates 303. The connecting plate 303 has a through hole 304 and the hinge plate 203 has a through hole 206 corresponding to the through hole 304. The limiting bolt 13 passes through the through hole 304 and the through hole 206 and is threadedly connected to the nut. The pad 3 is detachably connected to the hinge plate 203 through the limiting bolt 13, which improves the stability of the pad 3 and facilitates the replacement of the pad 3, thereby improving work efficiency.

[0054] A guide shaft 202 is fixedly mounted on the end face of the centering plate 2 away from the centering channel. The guide shaft 202 is perpendicular to the centering channel. A guide seat 8 is provided on the bracket. The guide seat 8 is movably connected to the bracket along the direction of the centering channel. A guide tube 801 matching the guide shaft 202 is fixedly mounted on the guide seat 8. The guide shaft 202 is located inside the guide tube 801. A T-shaped connector 802 is fixedly mounted at the lower end of the guide seat 8. Two L-shaped upright plates 9 are fixedly mounted on the bracket. A T-shaped groove matching the T-shaped connector 802 is formed between the two L-shaped upright plates 9. The T-shaped groove is arranged along the direction of the centering channel. The T-shaped connector 802 is movably connected to the inner side of the T-shaped groove. When the swing arm 4 swings to move the centering plate 2, the guide shaft 202 slides inside the guide tube 801, making the movement of the centering plate 2 more stable.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
