Technical Field
[0001] The utility model relates to the field of rust removal for steel surfaces, in particular to a reciprocating rust removal machine for threaded steel surfaces. Background Art
[0002] Rebar is the common name for hot-rolled ribbed steel bars. The grade of ordinary hot-rolled steel bars is composed of HRB and the minimum yield point of the grade, which are the first letters of the three words hot-rolled (Hotrol led), ribbed (Ribbed), and steel (Bars). After production, rebars are mostly placed in factories. When encountering humid temperatures, their surfaces are prone to rust and need to be derusted.
[0003] At present, when rebar is being derusted, due to its special surface structure, rust stains are prone to adhere to the grooves on its surface. In this way, at the end of the derusting, when encountering humid temperatures, rust will still appear on its surface, making it inconvenient to store it and reducing its service life. Utility Model Content
[0004] In order to solve the above problems, the purpose of the utility model is to provide a reciprocating rust remover for the surface of threaded steel to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model proposes a reciprocating threaded steel surface rust remover, comprising a workbench, a rust removal box is fixedly installed on the top of the workbench, and feeding holes are opened on both sides of the rust removal box;
[0006] A rust removal mechanism is provided inside the rust removal box, and the rust removal mechanism includes a wire ring, a fixed ring, a movable plate, a screw and a reciprocating motor. A reciprocating motor is fixedly installed on one side of the rust removal box, a screw that penetrates and extends into the rust removal box is fixedly installed on the output shaft of the reciprocating motor, a movable plate is sleeved on the outer ring of the screw, a fixed ring is fixedly installed on one side of the movable plate, a wire ring is fixedly installed on the inner wall of the fixed ring, and the wire ring rubs back and forth on the surface of the threaded steel to remove rust.
[0007] In one example, a fixing frame is fixedly installed on the top of the workbench, and fixing rods are fixedly installed on both inner walls of the fixing frame.
[0008] In one example, one end of the two fixing rods close to each other is rotatably connected to a roller.
[0009] In one example, an electric push rod is fixedly mounted on the top of the fixing frame, a connecting rod is fixedly mounted on the output shaft of the electric push rod, and the connecting rod penetrates and extends outside the fixing frame.
[0010] In one example, a lower pressing plate is fixedly mounted on one end of the connecting rod away from the electric push rod.
[0011] In one example, a guide rod is inserted into one side of the movable plate, and both ends of the guide rod are respectively fixedly connected to the rust removal box.
[0012] The reciprocating threaded steel surface rust remover proposed by the utility model can bring the following beneficial effects:
[0013] 1. A reciprocating rust remover for threaded steel surface can drive the screw to rotate by starting the reciprocating motor, and drive the moving plate to move, and drive the wire ring to move through the fixed ring, so as to frictionally remove rust on the threaded steel surface and clean the rust stains in the grooves on the surface, so as to prevent the threaded steel surface from rusting and reducing its service life, thereby removing rust on its surface and increasing its service life.
[0014] 2. This reciprocating threaded steel surface rust remover can drive the connecting rod to move downward by starting the electric push rod, and drive the lower pressure plate to move downward, so as to press the threaded steel on the roller to prevent the threaded steel from shaking during rust removal, so that it can be pressed and better rust removed.

DETAILED DESCRIPTION
[0020] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.
[0021] like Figure 1 to Figure 3As shown, the embodiment of the utility model provides a reciprocating threaded steel surface rust remover, comprising a workbench 1, a rust removal box 2 is fixedly installed on the top of the workbench 1, and feeding holes 9 are opened on both sides of the rust removal box 2;
[0022] A rust removal mechanism is provided inside the rust removal box 2, and the rust removal mechanism includes a wire ring 7, a fixed ring 6, a movable plate 5, a screw 4 and a reciprocating motor 3. The reciprocating motor 3 is fixedly installed on one side of the rust removal box 2, and the output shaft of the reciprocating motor 3 is fixedly installed with a screw 4 that penetrates and extends into the rust removal box 2. The outer ring of the screw 4 is sleeved with a movable plate 5, and a fixed ring 6 is fixedly installed on one side of the movable plate 5. The inner wall of the fixed ring 6 is fixedly installed with a wire ring 7, and the wire ring 7 rubs back and forth on the surface of the threaded steel to remove rust.
[0023] Specifically, a fixing frame 10 is fixedly installed on the top of the workbench 1 , and fixing rods 11 are fixedly installed on both inner walls of the fixing frame 10 . The fixing frame 10 fixes the fixing rods 11 , and the fixing rods 11 fix the rollers 12 .
