The amount of bar rebar in the national production and construction field is very large, and the bar production line is a production line specializing in the production of round bars. After rough rolling, intermediate rolling and finishing rolling, the steel billet is rolled into round steel bars of various specifications by multiple horizontal and vertical alternating two-roller rolling.

[0003] For example, the roller guide of a bar rolling mill with application number CN201721598171.4 includes a roller, a roller bracket, an arc groove, a rolling mill hole profile, a bearing end cover and a bearing. By arranging the roller as a guide, the entrance of the rolling mill hole profile of the bar rolling mill is provided with a roller guide. The roller guide has a high degree of matching with the rolling mill hole profile, and the bar rolled product can pass through the rolling mill hole profile accurately through the guide to enter the rolling mill, thereby ensuring the smooth progress of the rolling work of the rolling mill, and at the same time improving the qualified rate of the finished product quality.

[0004] The above patent proposes that the roller guide can usually only be used to guide and transport round steel bars of the same diameter or a diameter smaller than the mill hole during use. Such a setting leads to great limitations in the use of the guide structure.

[0005] Therefore, we proposed a round steel rolling mill guide improvement device to solve the above-mentioned problems. Utility Model Content

[0008] Preferably, the support assembly includes a concave square block and semicircular support blocks respectively arranged in the middle of the upper and lower ends of the outer surface of the concave square block, a long shaft is movably installed through the middle of the semicircular support block, and a roller shaft is movably installed on the outer surface of the long shaft.

[0009] Preferably, inner grooves are respectively provided on both sides of one end of the concave square block, and a plurality of stabilizing blocks are linearly and evenly fixedly installed on both sides of the inner wall of the inner groove.

[0010] Preferably, the concave square block has limit grooves at both ends, and a through groove is provided at the middle of the upper end of the inner cavity top surface of the inner groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By inserting the round steel bar into the mill hole groove at one end of the concave square block, the outer surface of the round steel bar will slide in contact with the round rollers movably installed at the upper and lower ends of the inner wall of the mill hole groove. When the round steel bar passes through the mill hole groove and reaches the notch at the other end of the mill hole groove, the round steel bar will slide in contact with the rolling components arranged on both sides of one end of the concave square block. According to the use requirements of the diameter of the round steel bar, the moving concave clamping block drives the extension block to slide in the inner cavity of the inner groove, so that the threaded long rod slides in the inner cavity of the through groove.
