when in use, the first step: the steel bar penetrates through a threading hole at the bottom of the column barrel (1) from bottom to top, penetrates between two rollers (15) from bottom to top, and finally penetrates through the middle part of the rotary table (6) from bottom to top, each grinding block (9) is in contact with the surface of the steel bar in an abutting mode, the steel bar penetrates out of the middle part of the rotary table (6) and is fixedly connected with traction equipment, the traction equipment is started, the steel bar is pulled upwards by the traction equipment to move from bottom to top, the upward movement of the steel bar drives the rollers (15) to rotate through the friction force, the rotation of the rollers (15) drives the corresponding rotating shafts (14) to rotate, the rotation of the rotating shafts (14) drives the gears (16) to rotate, the rotation of the gears (16) drives the gear rings (5) to rotate through the tooth transmission effect between the gears (16) and the gear rings (5), the rotation of the gear rings (5) synchronously drives the rotary table (6) to rotate, the rotation of the rotary table (6) synchronously drives each ejector, therefore, the ejector rods (8) synchronously drive the corresponding grinding blocks (9) to rotate around the central axis of the rotating disc (6), so that the grinding blocks (9) perform grinding, rust removal and deburring treatment on the surfaces of the steel bars; the first spring (12) always applies force pointing to the center of the turntable (6) to the sliding block (11), so that the sliding block (11) has a tendency of moving towards the inside of the groove (10), and then the sliding block (11) applies pressure to the corresponding grinding block (9) through the ejector rod (8), so that the grinding block (9) is always in tight contact with the surface of the steel bar in an abutting mode; step two: in the process that the steel bar moves upwards to drive the roller (15) to rotate, the roller (15) drives the gear ring II (17) to rotate through the rotating shaft (14), the gear ring II (18) is driven to rotate around the central axis of the column barrel (1) through the tooth transmission action between the gear ring II (17) and the gear ring II (18) in the rotating process, the gear ring II (18) synchronously drives the wedge blocks I (19) to rotate around the central axis of the column barrel (1), the wedge blocks I (19) are in abutting contact with the wedge blocks II (21) in the rotating process, the wedge blocks I (19) exert force on the wedge blocks II (21) to enable the wedge blocks II (21) to only move downwards, the moving synchronization of the wedge blocks II (21) drives the ring plate I (20) to move downwards, the downward movement of the ring plate I (20) compresses the spring II (23), and the spring II (23) obtains upward restoring force, the downward movement of the first ring plate (20) synchronously drives the second ring plate (25) to move downward through the guide rod (22), when the first wedge-shaped block (19) is separated from the second wedge-shaped block (21), the first wedge-shaped block (19) does not exert force on the second wedge-shaped block (21), so that the first ring plate (20) moves upwards and returns under the action of the upward restoring force of the second spring (23), and the upward movement of the first ring plate (20) synchronously drives the second wedge block (21) to move upward and reset, so that the next wedge block I (19) drives the ring plate I (20) to move downwards through the wedge block II (21), the second ring plate (25) is synchronously driven to move upwards by the guide rod (22) while the first ring plate (20) moves upwards, the rotary motion of the gear ring II (18) is converted into the vertical motion of the ring plate II (25), so that the ring plate II (25) can exert an intermittent driving action on the rapping mechanism; step three: in the process that the second ring plate (25) moves downwards, the second ring plate (25) applies pushing force to the upper end of the second connecting rod (28) through the first connecting rod (26), so that the upper end of the second connecting rod (28) is close to the outer peripheral wall of the column barrel (1), according to the lever principle, the lower end of the second connecting rod (28) simultaneously moves towards the direction far away from the column barrel (1), in the process, the hammer rod (29) is subjected to the action of the elastic force of the third spring (32) towards the outer side of the column barrel (1) to enable the hammer rod (29) to be far away from a steel rod, when the second ring plate (25) moves upwards, the second ring plate (25) applies pulling force to the upper end of the second connecting rod (28) through the first connecting rod (26), so that the upper end of the second connecting rod (28) moves towards the direction far away from the column barrel (1), according to the lever principle, the lower end of the second connecting rod (28) simultaneously moves towards the direction close to the column barrel (1), in the process, the lower end of the second connecting rod (28) applies pushing force towards the inner, make backing plate (31) drive hammer stem (29) be close to the billet to carry out the hammering to the surface of billet, backing plate (31) compress spring three (32) simultaneously, make spring three (32) obtain the restoring force of a directional column casing (1) outside, this restoring force has and moves down back connecting rod two (28) and when not producing the effect of power to backing plate (31) at crown plate two (25), drive hammer stem (29) and billet are kept away from and are reset, so reciprocal realization is continuous to carry out the hammering through hammer stem (29) to the billet surface.
