When the stacking mechanism pushes the deformed steel bar to move reversely along the conveying direction, the ribs on the surface of the deformed steel bar act on the conveying teeth on the surface of the conveying ring to drive the conveying ring to rotate, and at the moment, the clamping blocks do not limit the ratchet wheel. Through the structure, the condition that the mounting rollers synchronously rotate when the deformed steel bar reversely moves along the conveying direction is avoided, so that the blocking effect of the mounting rollers on the movement of the deformed steel bar is reduced, and the stacking mechanism can push the deformed steel bar to move to stack the ends of the deformed steel bar.

The end of the horizontal plate 81 penetrates the mounting plate 7 and is vertically and fixedly mounted with a first rack 85, and the mounting plate 7 is rotatably mounted with a second incomplete gear 86 engaged with the first rack 85. The mounting plate 7 is fixedly provided with a second motor 12 through a motor base, and the end part of an output shaft of the second motor 12 is fixedly connected with the second incomplete gear 86. The second incomplete gear 86 is driven to rotate by the second motor 12, and the second incomplete gear 86 drives the first rack 85 and the horizontal plate 81 to move downwards when entering a state of being meshed with the first rack 85, so as to drive the cutting knife 82 to cut the deformed steel bar. After the second incomplete gear 86 is out of the state of being engaged with the first rack 85, the first rack 85 and the horizontal plate 81 are restored by the resilient force of the support spring 84.
A second rack 13 is vertically slidably fitted on the mounting plate 7 to intermesh with the second partial gear 86. The bottom end of the second rack 13 is fixedly provided with a vertical rod 14. The bottom end of the vertical rod 14 is fixedly provided with a horizontal rod 15 which penetrates through the mounting plate 7. The horizontal rod 15 and the end plate 105 are fixedly connected through a pull wire 16. The second incomplete gear 86 is disengaged from the first rack 85 and then enters a state of being engaged with the second rack 13, and drives the second rack 13, the vertical rod 14 and the horizontal rod 15 to ascend. The horizontal rod 15 drives the end plate 105 to move horizontally through the pulling force of the pull wire 16 during the rising process, so that the second round rod 5 can descend synchronously through controlling the blanking mechanism 10. After the second incomplete gear 86 is disengaged from the second rack 13, the blanking mechanism 10 and the second round bar 5 are reset. Through the structure, the mutual cooperation of the blanking mechanism 10 and the cutting mechanism 8 is realized, and the processing efficiency is further improved.
The stacking mechanism 11 comprises a sliding plate 111 which is slidably fitted on the upper surface of the bottom plate 1 along the length direction of the first round bar 3, a horizontal seat 112 is fixedly installed on the surface of the sliding plate 111 facing the vertical plate 2, and the horizontal seat 112 is perpendicular to the first round bar 3. A stacking spring 113 is horizontally and fixedly arranged between the sliding plate 111 and the vertical plate 2. After the feeding mechanism 6 conveys the deformed steel bar, the horizontal base 112 is driven to be close to the end part of the deformed steel bar by pushing the sliding plate 111, and the stacking spring 113 is compressed. The horizontal seat 112 pushes the deformed steel bar to move along the reverse direction of the conveying direction after contacting the end part of the deformed steel bar; in this process, the threaded steel with uneven ends is piled up until the sliding plate 111 slides to the maximum of its sliding distance. The end surface of the horizontal base 112 facing the vertical plate 2 is uniformly and fixedly provided with a plurality of rubber blocks 114, and the rubber blocks 114 correspond to the positions between the first round bar 3 and the second round bar 5. The rubber block 114 plays a role in buffering and protecting the end of the deformed steel bar, so that the end of the deformed steel bar is prevented from being damaged.
The upper surface of the base plate 1 is slidably mounted with a third rack 115 engaged with the first partial gear 66 along the sliding direction of the sliding plate 111, and the end of the third rack 115 is fixedly connected with the sliding plate 111. The first incomplete gear 66 is disengaged from the gear 65 and then enters a state of being engaged with the third rack 115, so that the third rack 115 drives the sliding plate 111 to move, namely, the stacking mechanism 11 is driven to work, the linkage of the stacking mechanism 11 and the conveying mechanism 6 is realized, and the processing efficiency is further improved.
A limiting ring 68 which is coincident with the axial line of the conveying ring 63 is fixedly arranged on one side end face of the conveying ring 63, and is rotatably arranged on the mounting roller 62 through the limiting ring 68. The other end of the material conveying ring 63 is fixedly provided with a ratchet wheel 69 coinciding with the axis of the material conveying ring, a mounting cavity 610 is formed in the mounting roller 62, and a clamping block 611 matched with the ratchet wheel 69 is hinged to the side wall of the mounting cavity 610. When the gear 65 drives the mounting roller 62 and the material conveying ring 63 to rotate, the fixture block 611 has a limiting effect on the ratchet wheel 69, so that the ratchet wheel 69 and the material conveying ring 63 are limited to rotate, and the material conveying ring 63 conveys the deformed steel bars. When the stacking mechanism 11 pushes the deformed steel bar to move reversely along the conveying direction, the ribs on the surface of the deformed steel bar act on the conveying teeth 64 on the surface of the conveying ring 63 to drive the conveying ring 63 to rotate, and at the moment, the clamping block 611 does not limit the ratchet wheel 69. Through the structure, the situation that the mounting roller 62 synchronously rotates when the deformed steel bar reversely moves along the conveying direction is avoided, so that the blocking effect of the mounting roller 62 on the movement of the deformed steel bar is reduced, and the stacking mechanism 11 can push the deformed steel bar to move to stack the ends of the deformed steel bar. A plurality of balls 612 which are matched with the mounting rollers 62 in a rolling manner are uniformly arranged on the inner circumferential surface of the conveying ring 63 along the circumferential direction of the conveying ring, so that the friction force between the conveying ring 63 and the mounting rollers 62 is reduced, the resistance of the deformed steel bar when the deformed steel bar moves in the reverse direction along the conveying direction is improved, and the material stacking mechanism 11 is further ensured to push the deformed steel bar to move to align the ends of the deformed steel bar.
The working process of the high-strength deformed steel bar production and processing device in the embodiment is as follows: the formed deformed steel bars are sequentially placed between the first round rod 3 and the second round rod 5, and a plurality of deformed steel bars are parallel to each other after the deformed steel bars are placed. The first incomplete gear 66 is driven to rotate by the first motor 67, the gear 65, the mounting roller 62, the material conveying ring 63 and the material conveying teeth 64 are driven to rotate when the first incomplete gear 66 is in a meshed state with the gear 65, and in the process, the material conveying teeth 64 interact with ribs on the surface of the deformed steel bar and push the deformed steel bar to move along the axial direction of the first round rod 3 and the second round rod 5, so that the deformed steel bar is conveyed. When the first incomplete gear 66 is disengaged from the gear 65, the mounting roller 62, the feeding ring 63 and the feeding teeth 64 stop rotating, and the screw steel stops feeding.
After the screw-thread steel is conveyed by the conveying mechanism 6, the end parts of the screw-thread steel are orderly stacked by the stacking mechanism 11. The horizontal plate 81 then carries the cutting blade 82 downwards to cut the deformed steel bar, and the supporting spring 84 is compressed. The resilience of the support spring 84 causes the horizontal plate 81 and the cutting blade 82 to return after the cutting of the deformed steel bar is completed. At this moment, the second round rod 5 is driven to descend through the blanking mechanism 10, the gap between the second round rod 5 and the first round rod 3 is gradually increased in the descending process until the width of the gap exceeds the diameter of the deformed steel bar, the deformed steel bar falls from the gap into the material receiving box 9, and finally the second round rod 5 is driven to ascend and reset through the blanking mechanism 10.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
