[0028] like Figures 1 to 4 As shown, the utility model includes a frame 1, and the frame 1 includes a left side plate 1-1 and a right side plate 1-2. The left side plate 1-1 and the right side plate 1-2 are provided with two rows of circular holes, and the angle between the center line of the upper row of circular holes and the center line of the lower row of circular holes is 0.2 degrees. The frame 1 is located on the base 10, and eight groups of extrusion molding modules are arranged on the frame 1 from left to right.

[0029] The extrusion molding module includes an upper molding wheel-shaped mold 2 and a lower molding wheel-shaped mold 5 corresponding to each other, and the upper molding wheel-shaped mold 2 and the lower molding wheel-shaped mold 5 are respectively rotatably connected to the frame 1. The upper molding wheel-shaped mold 2 is provided with an upper rotating shaft 3 transversely, and the upper molding wheel-shaped mold 2 and the upper rotating shaft 3 are interference fit, and upper bearings 4 are provided at both ends of the upper rotating shaft 3, and the upper rotating shaft 3 is installed in the inner ring of the upper bearing 4 and interference fit therewith, and the two ends of the upper rotating shaft 3 are respectively rotatably connected to the left side plate 1-1 and the right side plate 1-2 through the upper bearing 4. The lower molding wheel-shaped mold 5 is provided with a lower rotating shaft 6 transversely, and the lower molding wheel-shaped mold 5 and the lower rotating shaft 6 are interference fit, and lower bearings 7 are provided at both ends of the lower rotating shaft 6, and the lower rotating shaft 6 is installed in the inner ring of the lower bearing 7 and interference fit therewith, and the two ends of the lower rotating shaft 6 are respectively rotatably connected to the left side plate 1-1 and the right side plate 1-2 through the lower bearing 7. The upper bearing 4 and the lower bearing 7 are both double-row short cylindrical roller bearings, which are respectively located in the circular holes of the left plate 1-1 and the right plate 1-2, and are interference fit with the left plate 1-1 and the right plate 1-2.

[0030] The lower forming wheel mold 5 is also connected to a transmission gear 8, and there is an interference fit between the transmission gear 8 and the lower rotating shaft 6. An intermediate gear 9 is also provided between adjacent extrusion molding modules, and the intermediate gear 9 is installed on the frame 1 (specifically the left side plate 1-1) by a rotation connection and meshes with the transmission gears 8 of the extrusion molding modules on both sides at the same time.

[0031] By setting up multiple groups of extrusion molding modules in the frame 1, round steel can be extruded simultaneously from top to bottom, so that the round steel can be formed at one time at room temperature without heating energy consumption, thereby reducing processing costs, improving processing efficiency, and following the green and environmentally friendly development concept; and because the round steel is not heated and oxidized, the strength of the ribs formed by the processing is significantly improved compared with the hot rolling processing, thereby improving the tensile strength of the resin anchor rod and ensuring the safe and smooth progress of the support operation.

[0032] The outer circumferences of the upper forming wheel die 2 and the lower forming wheel die 5 are uniformly distributed with grooves 11, which are arranged at an angle relative to the axis of the outer circumference, and the grooves 11 are used to extrude ribs on the surface of the round steel. The outer circumferences of the upper forming wheel die 2 and the lower forming wheel die 5 are uniformly distributed with inclined arc surfaces 12, and the grooves 11 are formed between adjacent inclined arc surfaces 12. By distributing the inclined arc surfaces 12 and the grooves 11 on the outer circumferences of the upper forming wheel die 2 and the lower forming wheel die 5, corresponding ribs can be rolled out on the round steel.

[0035] Power is provided to the lower rotating shaft 6 at the feeding end, so that the lower rotating shaft 6 starts to rotate, thereby driving the lower forming wheel mold 5 to rotate synchronously. Under the action of the intermediate gear 9, all the transmission gears 8 start to rotate synchronously with the lower rotating shaft 6. The round steel is extended from the feeding end into the conical molding cavity surrounded by the upper and lower inclined arc surfaces 12. Under the action of friction, the round steel drives the upper forming wheel mold 2 to rotate one by one. Under the joint extrusion of the upper forming wheel mold 2 and the lower forming wheel mold 5, ribs are formed on the round steel, and the resin anchor processing is completed.
