Description
Technical Field
[0001] This utility model relates to the field of rolling mill equipment, specifically to a ribbed mill for rolling fine threaded ribbed anchor bars. Background Technology
[0002] Rib alignment is crucial when producing threaded ribbed anchor bars. Rib alignment is time-consuming and labor-intensive after changing rolls to different specifications. Due to the difference between the roll diameter and the coupling outer diameter, it is impossible to determine the required roll adjustment distance from the coupling adjustment distance. On-site workers often adjust the wrong direction, which greatly reduces the adjustment efficiency.
[0003] In the existing technical solutions, the high-precision threaded rib anchor bar rebar rib-matching mill train with authorization announcement number CN 216937705 U, through the position adjustment sleeve, pushes or pulls the rolls to move, and under the guidance of the inclined rib plate, realizes the slight up and down movement of the rolls. However, it only adjusts the height position of the rolls and cannot make the upper and lower roll transverse ribs strictly aligned, which cannot meet the rib alignment requirements of the finished product when precision rolling threaded rib anchor bars. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a rib-aligning machine for rolling precision threaded rib anchor bars, which can achieve strict alignment of the upper and lower roller transverse ribs, meet the requirements of finished product rib alignment, and can be quickly and stably adjusted into position.
[0005] To achieve the above objectives, the present invention proposes the following technical solution:
[0006] A rib-matching mill for rolling precision threaded ribbed anchor bars includes a flat head, a flat head sleeve, a phase adjustment structure, a connecting shaft, and rolls; the phase adjustment structure includes a first coupling, a second coupling, a worm gear assembly, a locking screw, an adjusting bolt, and a connecting bolt; the flat head is connected to the first coupling via the flat head sleeve, and the rolls are connected to the second coupling via the connecting shaft.
[0007] The first coupling has circumferentially distributed positioning holes and radially arranged vertical slides; the second coupling has elongated arc-shaped holes, the center of the arc of the elongated arc-shaped holes is coaxial with the second coupling, the elongated arc-shaped holes of the second coupling correspond one-to-one with the positioning holes of the first coupling, and the central axis of the positioning holes passes through the arc center line of the elongated arc-shaped holes. The connecting bolts pass through the positioning holes of the first coupling and the elongated arc-shaped holes of the second coupling and are connected by nuts, so that the second coupling is connected to the first coupling and always remains coaxial.
[0008] The worm gear assembly includes a worm and two eccentric push rods. The worm is a double-ended worm with two sections of threads with opposite directions and the same pitch. Each eccentric push rod includes a sliding body and a connecting rod, with the connecting rod and sliding body connected laterally eccentrically. The sliding bodies of the two eccentric push rods are threadedly connected to the threads of the worm. The worm is vertically rotatably mounted in a vertical slide, and the central axis of the worm passes through the central axis of the first coupling. The sliding bodies of the two eccentric push rods cooperate with the vertical slide, allowing them to slide along the vertical slide. The two eccentric push rods are centrally symmetrical about the center of the first coupling, meaning the connecting rods of the two eccentric push rods have opposite eccentric directions, the same eccentric distance, and the same distance between the two eccentric push rods and the center of the first coupling.
[0009] The second coupling has a radially arranged keyway. The connecting rods of the two eccentric push rods are engaged in the keyway. When the line connecting the two eccentric push rods rotates, it can drive the second coupling to rotate. When the second coupling rotates, the connecting bolts rotate relative to each other in the elongated arc-shaped hole. The locking screw is located on the first coupling. When the locking screw is screwed in, it can hold the locking worm. When the locking screw is screwed out, the worm can rotate freely. The adjusting bolt passes through the first coupling and is coaxially connected to the worm. The synchronous rotation of the worm is achieved by rotating the adjusting bolt.
[0010] The aforementioned locking set screw, used to lock the worm gear and restrict its rotation, is existing technology.
[0011] Preferably, the central axis of the positioning hole passes through the midpoint of the arc center line of the elongated arc hole.
[0012] Preferably, the vertical slide is provided with bearing seats at both ends, namely a first bearing seat and a second bearing seat; the worm gear is installed in the vertical slide through the first bearing seat and the second bearing seat.
[0013] Preferably, the first bearing housing has a threaded through hole, and the second coupling has a long arc-shaped set screw through hole. The locking set screw passes through the set screw through hole and the threaded through hole and can contact the worm. The locking set screw enters the first bearing housing and can lock the worm to prevent it from rotating. When the locking set screw is unscrewed away from the worm, the worm returns to its free rotation state.
[0014] Preferably, the second coupling is provided with an LCD indexing display disk; the first coupling is provided with a zero position mark, and the zero position of the LCD indexing display disk coincides with the zero position mark, so that the rotation angle of the second coupling relative to the first coupling is displayed on the LCD indexing display disk; the LCD indexing display disk has a roll diameter conversion function, which can be obtained by inputting the roll diameter.
[0015] The aforementioned liquid crystal indexing display panel is existing technology, which can be directly used by those skilled in the art.
[0016] Specifically, the threads on the worm are a first thread and a second thread, and the two eccentric push rods are a first eccentric push rod and a second eccentric push rod. The first eccentric push rod is threaded to the first thread, and the second eccentric push rod is threaded to the second thread.
[0017] Assuming the first thread is right-handed and the second thread is left-handed, with the first thread on top and the second thread on the bottom, the first eccentric push rod is eccentric to the left and the second eccentric push rod is eccentric to the right.
[0018] When the phase adjustment of the rolls is required, first measure the distance between the ribs of the upper and lower rolls, and then determine the phase adjustment angle and direction based on the rib distance. Finally, determine the rotation angle and direction of the worm gear based on the phase adjustment angle.
[0019] Secondly, the locking screw is moved away from the worm, and the worm is in a free-rotating state; the nut of the connecting bolt is in a loosened state, that is, the second coupling is in a coaxial and rotatable state relative to the first coupling.
[0020] Then, when the adjusting bolt is rotated to drive the worm to rotate counterclockwise, the first eccentric push rod moves upward and the second eccentric push rod moves downward. The line connecting the two connecting rods will then rotate clockwise, thereby driving the second coupling to rotate clockwise, thus realizing the clockwise phase adjustment of the roll.
[0021] When the adjusting bolt is rotated, the worm gear rotates clockwise, the first eccentric push rod moves down, the second eccentric push rod moves up, and the line connecting the two connecting rods rotates counterclockwise, which in turn drives the second coupling to rotate counterclockwise, thus realizing the counterclockwise phase adjustment of the roll.
[0022] After completing the phase adjustment, screw in the locking set screw to press and tighten, lock the worm gear to prevent rotation, and then tighten the nut to lock the connection between the second coupling and the second coupling, thereby completing the upper and lower roller rib alignment operation.
[0023] The beneficial effects of this utility model are as follows:
[0024] This utility model consists of a phase adjustment structure composed of a first coupling, a second coupling, a worm gear assembly, a locking screw, an adjusting bolt, and a connecting bolt. By rotating the adjusting bolt, the phase of the second coupling can be adjusted to achieve the phase adjustment of the roll and meet the requirements of rib alignment.
[0025] By adopting the above solution, this utility model can achieve strict alignment of the upper and lower roller ribs, meet the requirements of finished product rib alignment, and can be quickly and stably adjusted into position. Attached Figure Description

[0035] First embodiment:
[0036] like Figures 1-3 As shown, a ribbed rebar rolling mill for precision threaded anchor rods includes a flat head 1, a flat head sleeve 2, a phase adjustment structure 3, a connecting shaft 4, and rolls; the phase adjustment structure 3 includes a first coupling 31, a second coupling 32, a worm gear assembly 33, a locking screw 34, an adjusting bolt 35, and a connecting bolt 36; the flat head 1 is connected to the first coupling 31 via the flat head sleeve 2, and the rolls are connected to the second coupling 32 via the connecting shaft 4.
[0037] The first coupling 31 is provided with circumferentially distributed positioning holes 311 and radially arranged vertical slides 314; the second coupling 32 is provided with an elongated arc-shaped hole 321, the center of the arc center line of the elongated arc-shaped hole 321 is coaxial with the second coupling 32, the elongated arc-shaped hole 321 of the second coupling 32 corresponds one-to-one with the positioning holes 311 of the first coupling 31, and the central axis of the positioning hole 311 passes through the arc center line of the elongated arc-shaped hole 321. The connecting bolt 37 passes through the positioning hole 311 of the first coupling 31 and the elongated arc-shaped hole 321 of the second coupling 32 and is connected with a nut, so that the second coupling 32 is connected to the first coupling 31 and always maintains a coaxial state.
[0038] The worm gear assembly 33 includes a worm 333 and two eccentric push rods; the worm 333 is a double-ended worm, and has two sections of threads with opposite directions and the same pitch; the eccentric push rod includes a sliding body and a connecting rod, and the connecting rod is laterally eccentrically connected to the sliding body; the sliding bodies of the two eccentric push rods are threadedly connected to the threads of the worm 333 respectively; the worm 333 is vertically rotatably installed in the vertical slide 314, and the central axis of the worm 444 passes through the central axis of the first coupling 31; the sliding bodies of the two eccentric push rods cooperate with the vertical slide, and the sliding bodies of the two eccentric push rods can slide along the vertical slide 314; the two eccentric push rods are centrally symmetrical about the center of the first coupling 31, that is, the eccentric directions of the connecting rods of the two eccentric push rods are opposite, the eccentric distances are the same, and the distances between the two eccentric push rods and the center of the first coupling 31 are the same.
[0039] The second coupling 32 has a radially arranged keyway 322. The connecting rods of the two eccentric push rods are engaged in the keyway 322. When the connecting line of the two eccentric push rods rotates, it can drive the second coupling 32 to rotate. When the second coupling 32 rotates, the connecting bolt 37 rotates relative to each other in the elongated arc hole 321. The locking screw 34 is provided on the first coupling 31. When the locking screw 34 is screwed in, it can hold the locking worm 333 in place. When the locking screw 34 is unscrewed, the worm 333 can rotate freely. The adjusting bolt 35 passes through the first coupling 31 and is coaxially connected to the worm 333. The synchronous rotation of the worm 333 is achieved by rotating the adjusting bolt 35.
[0040] Specifically, the threads on the worm 333 are a first thread and a second thread, and the two eccentric push rods are a first eccentric push rod 331 and a second eccentric push rod 332. The first eccentric push rod 331 is threaded to the first thread, and the second eccentric push rod 332 is threaded to the second thread.
[0041] Assuming the first thread is right-handed and the second thread is left-handed, with the first thread on top and the second thread on the bottom, the first eccentric push rod 331 is eccentric to the left and the second eccentric push rod 332 is eccentric to the right.
[0042] When the phase adjustment of the rolls is required, first measure the misalignment distance between the upper and lower rolls, and then determine the phase adjustment angle and direction based on the misalignment distance. Finally, determine the rotation angle and direction of the worm 333 based on the phase adjustment angle.
[0043] Secondly, the locking screw 34 is moved away from the worm 333, and the worm 333 is in a free rotation state; the nut of the connecting bolt 37 is in a loose state, that is, the second coupling 32 is in a coaxial and rotatable state relative to the first coupling 31.
[0044] Then, when the adjusting bolt 35 is rotated to drive the worm gear 333 to rotate counterclockwise, the first eccentric push rod 331 moves upward and the second eccentric push rod 332 moves downward. The connecting line of the two connecting rods will rotate clockwise, which in turn drives the second coupling 32 to rotate clockwise, thereby realizing the clockwise phase adjustment of the roll.
[0045] When the adjusting bolt 35 is rotated to drive the worm gear 333 to rotate clockwise, the first eccentric push rod 331 moves down and the second eccentric push rod 332 moves up. The line connecting the two connecting rods will then rotate counterclockwise, thereby driving the second coupling 32 to rotate counterclockwise, thus realizing the counterclockwise phase adjustment of the roll.
[0046] After completing the phase adjustment, screw in the locking screw 34 to press and tighten, lock the worm gear 333 to prevent rotation, and then tighten the nut to lock the connection between the second coupling 32 and the second coupling 31, thereby completing the upper and lower roller rib alignment operation.
