Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: a thread rolling material channel mechanism for a step bolt with a long polished rod and a short thread comprises a thread rolling material channel 1, wherein a support frame 2 and a material pushing seat 3 are connected to the side surface of the thread rolling material channel 1, two adjusting blocks 4 are symmetrically arranged on the support frame 2, a plurality of connecting holes 5 which are uniformly distributed in the longitudinal direction are formed in each adjusting block 4, the material channel mechanism further comprises an auxiliary material channel 6, two connecting rods 7 which correspond to the adjusting blocks 4 one by one are connected to the auxiliary material channel 6, the bottom ends of the connecting rods 7 are connected with the connecting holes 5 through connecting pieces, a material pushing piece 8 which is matched with the auxiliary material channel 6 is arranged at the top end of the material pushing seat 3,
the material pushing sheet 8 is provided with a material blocking rod 9 and a material pushing rod 10, the outlet end of the auxiliary material channel 6 is further rotatably connected with a circular arc-shaped swinging feeding arc-shaped plate 12 through a rotating shaft 11 with a torsion spring, the inner wall of the swinging feeding arc-shaped plate 12 is matched with the outer wall of a polished rod part of a processed bolt 13, and the outlet end of the thread rolling channel 1 is further provided with a thread rolling movable plate 14 and a thread rolling static plate 15 which are matched with each other.
The utility model discloses to step bolt's of long polished rod short thread rolling material way mechanism's working process as follows: the inlet end of the thread rolling material channel mechanism is connected with the outlet end of a vibration feeding machine, under the action of the vibration feeding machine, a plurality of step bolts 13 with long polished rods and short threads to be processed move along the thread rolling material channel mechanism, the tops of the bolts 13 are clamped on the upper end surface of an auxiliary material channel 6, the thread part 16 at the bottom end of the bolts 13 is positioned in the thread rolling material channel 1,
when the bolt 13 moves to the tail end of the mechanism, the smooth rod part on the bolt 13 is in contact with the inner wall of the feeding arc-shaped plate 12 positioned at the end part of the auxiliary material channel 6, and at the moment, a sensor on the thread rolling machine detects that the bolt 13 moves in place, the driving mechanism arranged on the bolt controls the pushing sheet 8 to move, when the pushing sheet 8 moves, on one hand, the material blocking rod 9 is driven to extend out to block the coming material behind, so that only one bolt 13 is ensured to be subjected to thread rolling operation at one time, on the other hand, the pushing rod 10 is driven to extend out, the bolt 13 is obliquely pushed out by the pushing rod 10, the thread part 16 at the bottom end of the bolt enters a thread rolling gap between the thread rolling movable plate 14 and the thread rolling static plate 15, then the thread rolling machine drives the thread rolling movable plate 14 to move, and under the combined action of the thread rolling movable plate 14 and the;
at the initial stage of contact between the material pushing sheet 8 and the bolt 13, because the inner wall of the swinging feeding arc-shaped plate 12 is in close contact with the polished rod part of the bolt 13, a counter-leaning force can be provided, so that the longer bolt 13 is ensured not to incline because of the stress point being relatively leaned on, the swinging feeding arc-shaped plate 12 swings and opens under the action of force, and finally the bolt 13 can be separated from the swinging feeding arc-shaped plate 12 and enter a thread rolling gap between the thread rolling movable plate 14 and the thread rolling static plate 15
After the thread rolling operation of the first bolt 13 is finished, the pushing sheet 8 is recovered, under the action of the torsion spring, the swinging feeding arc-shaped plate 12 returns to the initial state, the second bolt 13 which loses the blocking of the blocking rod 9 moves to the end part of the material channel and contacts with the inner wall of the swinging feeding arc-shaped plate 12, the pushing sheet 8 stretches out again, the operation is repeated, and by analogy, the thread rolling operation of the thread part 16 at the bottom end of the step bolt 13 with a plurality of long polished rod short threads is realized one by one.
