[0002] Anchor bolts are screws used to fasten machines to the ground, also called anchor screws. They are widely used in railways, highways, large-span steel structures in cement plants and large buildings. They are used to fix various equipment, structural members, etc. on concrete foundations to ensure their stability and safety. When producing anchor bolts, the surface of the screw is rolled by a thread rolling machine to form a thread. When rolling the thread, the screw is placed between two rolling wheels, and the thread is opened on the surface of the screw by the rotation of the rolling wheels.
[0003] When producing anchor bolts, the lengths produced vary. The common full length of anchor bolts is usually between 50mm-2000mm.

It should be supplemented that the reciprocating screw 6 and the screw nut 7 are rolled threadedly transmitted, and the screw nut 7 can move up and down on the reciprocating screw 6. Driven by the sliding rod 12, the slider 10 moves synchronously on the sliding rod 9, thereby driving the lifting rod 13 to move downward, so that the placement semi-ring 2 4 is attached to the placement semi-ring 1 3, and after the attachment, the placement semi-ring 1 3 can be fixed to the placement semi-ring 2 4 by a fixing piece, and the fixing piece includes It includes a fixing plate 14 and a fixing plate 2 15, each of the two sides of the placed semi-ring 1 3 is fixedly installed with a fixing plate 14, and a fixing rod 25 is fixedly installed on the top of each fixing plate 14, and each of the two ends of the placed semi-ring 2 4 is fixedly installed with a fixing plate 2 15, and a through groove matched with the fixing rod 25 is opened on the fixing plate 2 15, when moving downward, the fixing plate 2 15 moves downward with it, and the through groove of the fixing plate 2 15 is inserted into the fixing rod 25, so that the placed semi-ring 1 3 and the placed semi-ring 2 4 are fixed.
[0029] When the reciprocating screw 6 rotates, Figure 3 As shown, the transmission assembly can simultaneously drive the moving rod 2 to move forward in the slide groove, thereby driving the light rod to move forward a certain distance, so as to approach the thread rolling wheel. The transmission assembly includes a rotating shaft 16, a gear ring 17 and a rack 18. The rotating shaft 16 is fixedly mounted on the bottom end of the reciprocating screw 6, and the rotating shaft 16 is coaxially connected to the reciprocating screw 6. The gear ring 17 is fixedly mounted on the rotating shaft 16. The rack 18 is fixedly mounted on the side surfaces of the two moving rods 2, and the gear ring 17 is meshed with the rack 18. Specifically, the reciprocating screw 6 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the gear ring 17 to rotate, and the gear ring 17 drives the rack 18 meshed with it to move, thereby moving the moving rod 2 forward, and when the moving rod 2 drives the placing half ring 1 3 to move forward, because the placing half ring 1 3 is fixedly connected with the placing half ring 2 4 at this time, the placing half ring 2 4 can be driven by the sliding rod 12 to slide forward synchronously in the slide groove of the sliding frame 11, and stop when the side surface of the light rod approaches the side surfaces of the two thread rolling wheels.
[0030] It should be supplemented that the placing half ring 1 3 and the placing half ring 2 4 can be detachably mounted on the moving rod 2 and the lifting rod 13 by bolts or buckles, so that when producing bolts 23 of different sizes, the placing half ring 1 3 and the placing half ring 2 4 corresponding to the light rod can be replaced, so that the light rod can fit when placed on the placing half ring 1 3, and the inner side walls of the placing half ring 1 3 and the placing half ring 2 4 are made of smooth material, the light rod can slide in the placing half ring 1 3 and the placing half ring 2 4, and a protective cover 24 is detachably mounted on the support frame, and the gear ring 17 is located in the protective cover 24, and the rotating shaft 16 is rotatably mounted on the top of the protective cover 24. During processing, in order to prevent impurities or debris from splashing onto the gears, the protective cover 24 can protect the gears.
[0031] After the move is completed, Figure 4 and Figure 5 As shown, the polished rod is pushed between the two thread rolling wheels by the pushing assembly for thread processing. The pushing assembly includes a moving frame 19, an electric cylinder 20, a pushing plate 21 and a limiting member. A slide groove is provided on the side of the support platform 26. The moving frame 19 is slidably installed in the slide groove. The electric cylinder 20 is installed on the moving frame 19.

The limiting plate 22 is fixedly installed on the side of the support platform 26, and a threaded hole is provided on the limiting plate 22. A threaded hole is provided on the side of the movable frame 19, and the bolt 23 is threadedly connected in the threaded hole. Specifically, the movable frame 19 is pushed to make the side of the movable frame 19 fit with the side of the limit plate 22. Because when the side of the movable frame 19 fits with the side of the limit plate 22, the pushing plate 21 and the center of the circle on which the semi-ring 13 is placed are located at the same horizontal position. At this time, the pushing plate 21 is located on the side of the light rod, and then the bolt 23 is threadedly connected into the threaded holes of the movable frame 19 and the limit plate 22 to fix them, and then the electric cylinder 20 is started. The output end of the electric cylinder 20 slowly pushes the light rod forward to between the two rolling wheels, thereby performing thread processing.
[0032] Working principle: When threading the anchor bolt 23, first place the polished rod in the placing half ring 1 3, then start the motor 8, drive the screw nut 7 and the slider 10 to move on the reciprocating screw 6 and the slider 9 respectively, move the placing half ring 2 4 down until it fits the placing half ring 1 3, and then the fixing rod 25 is inserted into the through groove of the fixing plate 2 15, so that the placing half ring 1 3 and the placing half ring 2 4 are fixed together, ensuring that the placing half ring 1 3 and the placing half ring 2 4 move forward synchronously when moving forward, and the rotating shaft 16 is driven to rotate while the reciprocating screw 6 rotates, thereby driving the gear ring 17 to rotate, and the gear ring 17 drives the rack 18 to move, and the placing half ring 2 4 When moving downward, the moving rod 2 is synchronously driven to move forward so that the side of the polished rod is close to the thread rolling wheel. After the movement is completed, the sliding moving frame 19 is pressed against the side of the limit plate 22, and then the bolt 23 is threadedly connected and fixed. After the fixation is completed, the electric cylinder 20 is started, and the output end of the electric cylinder 20 drives the pushing plate 21 to move forward, pushing the polished rod to slide in the placing semi-ring 1 3 and the placing semi-ring 2 4, so that it moves forward to between the two thread rolling wheels for thread rolling. After the thread rolling is completed, the thread rolling is stopped, and then the output end of the motor 8 is started in reverse. When the placing semi-ring 2 4 moves upward, the moving rod 2 moves backward, and the polished rod with the thread processed is moved out, and then the staff takes it and collects it.
