From the initial position top view 2 and the A-A cross section 4, the mechanism mainly comprises a main bracket 1, a cylinder 2, a pushing cylinder 3, a rotator bottom plate 4, a rotating shaft 5, a bearing 6, a bearing seat 7, a pressure spring 8, a pressure spring fixing block 9, a transverse adjusting block 10, a longitudinal adjusting block 11, a bearing block 12, a front end adjusting block 13, a bearing 14, an L-shaped bearing seat 15, a bearing pin 16, a pressure spring fixing block 17, a bearing contact block 18 (shown in fig. 3) and the like.

The whole mechanism is of a symmetrical structure, the cylinder 2 in the top view 2 is fixed with the main support 1, and the pushing cylinder 3 can transversely slide in a chute in the main support 1 through the thrust of the cylinder 2. The rotating body bottom plate 4 is fixed on the main bracket 1 by bolts, a rotating shaft 5 is arranged on the rotating body bottom plate, a bearing 6 (shown as A-A cross section) is arranged on the shaft 5, the bearing 6 is fixed through two step holes of a bearing seat 7, the shaft 5 is fixed on the rotating body bottom plate 4 through an inner hole of the bearing 6, and the bearing seat 7 can rotate around the rotating shaft 5. The upper right of the bearing seat 7 is provided with a pressure spring fixing block 9 which is fixed with a pressure spring fixing block 17 fixed on the rotator bottom plate 4 to fix the pressure spring 8. When the bearing contact block 18 (fig. 3) fixed below the pushing cylinder 3 contacts with the bearing 14, the compression spring 8 is compressed (fig. 5). At this time, the compression spring fixing block 9, the transverse adjusting block 10, the longitudinal adjusting block 11, the bearing block 12 and the front end adjusting block 13 are all rotated around the rotation shaft 5 and slowly opened for an angle. The transverse adjusting block 10 is fixed on the bearing seat 7 through bolts and can be adjusted transversely (left and right) to find a supporting point for a bar. The longitudinal adjusting blocks 11 are arranged below the transverse adjusting blocks 10, so that longitudinal adjustment is realized, the stability of bar stock placed on the two material bearing blocks 12 is guaranteed, the material bearing blocks 12 are connected with the longitudinal adjusting blocks 11 through bolts, gaskets with different thicknesses are added in the middle, the upper and lower positions of the material bearing blocks 12 are conveniently adjusted, and the center of the bar stock is guaranteed to be consistent with the center of the pushing cylinder 3. The front end adjusting block 13 is arranged on the right side of the longitudinal adjusting block 11, the height of the right end of the bar is adjusted, and the right end of the bar is ensured to smoothly enter the thread rolling equipment for processing. An L-shaped bearing seat 15 is arranged below the longitudinal adjusting block 11, a bearing 14 is fixed on the L-shaped bearing seat 15 through a bearing pin 16, the bearing 14 can rotate around the bearing pin 16, and the height of the bearing 14 is consistent with the height of a bearing contact block 18.

The working process comprises the following steps: as shown in fig. 3, when the pushing cylinder 2 pushes the pushing cylinder 3 to advance, the bearing contact block 18 fixed below the pushing cylinder 3 contacts with the bearing 14, at this time, the compression spring 8 is slowly compressed, and the compression spring fixing block 9, the transverse adjusting block 10, the longitudinal adjusting block 11, the bearing block 12 and the front end adjusting block 13 all rotate around the rotation shaft 5 and slowly open by an angle until the widest part of the bearing contact block 18 contacts with the bearing 14, i.e. the limit position of opening of the rotary opening and closing supporting mechanism is reached (as shown in fig. 5), at this time, the bar enters the thread rolling device. When the pushing cylinder 3 continues to advance, the pushing cylinder 3 advances in the space where the rotary opening and closing support mechanism opens, without interfering with the material bearing block 12, and colliding with the material bearing block. At this time, the bar is no longer supported by the carrier block 12 and the front end adjusting block 13, and the bar is not dropped due to the action of the thread rolling device and the pushing cylinder 3. When the thread rolling is finished, the pushing cylinder 3 slowly retreats under the action of the air cylinder 2, and the bar material after the thread rolling falls from the gap opened by the rotary opening and closing supporting mechanism and enters the conveyor below. As the push cylinder 3 and the bearing contact block 18 below are retreated, the bearing 14 is gradually separated from the bearing contact block 18, and the rotary opening and closing support mechanism is gradually restored to the initial state under the action of the spring 8 (see fig. 1 and 2).

Working principle: the worker or the robot only needs to put the bar on the rotary opening and closing supporting mechanism, the pushing cylinder is started, the pushing cylinder can push the bar to the designated position, and when the designated position is reached, the rotary opening and closing supporting mechanism can be slowly opened, and the pushing cylinder can continuously advance until the thread rolling is completed. When the pushing cylinder retreats, the rotary opening and closing support mechanism restores to an initial (closed) state.
