The utility model has the advantages that: because the output shaft is provided with the unidirectional output mechanism, the gear box can only drive the pinch roller to rotate in a unidirectional way. On alignment mechanism working process, this drive mechanism's last pinch roller and lower pinch roller are only injectd the reinforcing bar in certain position, prevent the reinforcing bar excessive swing, guarantee the alignment operation of reinforcing bar, both do not sticis the reinforcing bar and pull, only the reinforcing bar breaks away from alignment mechanism completely, go up the pinch roller and press the pinch roller just press from both sides tight reinforcing bar down, thereby send out the reinforcing bar completely, with this avoid the staff to pull out the straightener with remaining reinforcing bar, can prevent again that drive mechanism's rotational speed is greater than when alignment mechanism, increase the operating pressure of gearbox, protect the gearbox. Even in the course of the work, when last pinch roller and pinch roller compact reinforcing bar, when the speed that straightening mechanism drive reinforcing bar gos forward was greater than this drive mechanism's rotational speed, the reinforcing bar can promote pinch roller and pinch roller when rotating with higher speed, one-way output mechanism can effectively interrupt the reinforcing bar and drive pinch roller pivoted power transmission to the gearbox, plays the effect of protection gearbox equally, the utility model discloses simple structure, practical reliable.
Drawings
The invention will be further described with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
Referring to fig. 1, the auxiliary traction mechanism of the steel bar straightener comprises a gearbox 1 and a wheel seat 2, wherein an upper pinch roller 16 and a lower pinch roller 3 are installed on the wheel seat 2, the lower pinch roller 3 is connected with an output shaft 4 of the gearbox 1, and a one-way output mechanism is arranged on the output shaft 4. Because the output shaft is provided with the unidirectional output mechanism, the gear box 1 can only drive the lower pinch roller 3 to rotate in a unidirectional way. On alignment mechanism working process, this drive mechanism's last pinch roller 16 and pinch roller 3 only inject the reinforcing bar in certain position, prevent the excessive swing of reinforcing bar, guarantee the alignment operation of reinforcing bar, both do not sticis the reinforcing bar and pull, only the reinforcing bar breaks away from alignment mechanism completely, it just presss from both sides tight reinforcing bar to go up pinch roller 16 and pinch roller 3, thereby see the reinforcing bar out completely, thereby avoid the staff to pull out the straightener with remaining reinforcing bar, when can prevent again that drive mechanism's rotational speed is greater than alignment mechanism, increase the operating pressure of gearbox, protection gearbox 1. Even in the course of the work, when last pinch roller 16 and pinch roller 3 compress tightly the reinforcing bar, when alignment mechanism drive reinforcing bar speed of advancing was greater than this drive mechanism's rotational speed, the reinforcing bar can promote to go up pinch roller 16 and pinch roller 3 when rotating with higher speed, one-way output mechanism can effectively interrupt the reinforcing bar and drive the power transmission to gearbox 1 of pinch roller pivoted, plays the effect of protection gearbox 1 equally.
The unidirectional output mechanism mainly comprises a unidirectional bearing 5, the unidirectional bearing 5 is tightly embedded into the mounting groove of the output shaft 4, and the inner ring of the unidirectional bearing 5 is tightly connected with a rotating shaft 6 connected with the lower pinch roller 3. Of course, the one-way output mechanism can adopt the form such as clutch to realize the one-way output of gearbox, but will greatly increased production and use cost like this, the utility model discloses mainly adopt one-way bearing to constitute is the simplest economic effectual form.
In order to effectively limit the advancing direction of the steel bars and prevent excessive shaking, the lower pressing wheel 3 is connected with the output shaft 4, and the circumferential surface of the lower pressing wheel 3 is provided with an annular V-shaped groove 7. When the reinforcing steel bar is positioned in the annular V-shaped groove 7, the advancing direction of the reinforcing steel bar can advance along the tangential direction of the V-shaped groove 7, so that the deviation is avoided.
In addition, the circumferential surface of the upper pressure wheel 16 is provided with pressing teeth 8 which are concave and convex alternately, and the pressing teeth 8 are arranged along the axial direction. The axial pressing teeth 8 are matched with the annular V-shaped grooves 7, so that the deviation of the steel bars in the advancing process can be further prevented. When the upper pressing wheel and the lower pressing wheel are required to pull the steel bars, the upper pressing wheel and the lower pressing wheel can effectively clamp the steel bars and send the steel bars out of the straightener to prevent slipping.
The upper pinch roller 16 is connected with the roller seat 2 through a roller shaft 10 arranged on the sliding seat 9, grooves 11 are arranged on two sides of the sliding seat 9, the grooves 11 are sleeved on the inner sides of two guide posts 12 of the roller seat, and an adjusting screw 14 and a compression spring 15 which are connected with an upper top plate 13 of the guide posts 12 are arranged above the sliding seat 9. The adjusting screw 14 is rotated, and the gap between the upper wheel and the lower wheel is changed, so that the straightening production operation of the reinforcing steel bars with different diameters is adapted.
Certainly, in order to cooperate with the subsequent cutting process, a set of roller and sensor for measuring the length of the steel bar can be arranged on the wheel seat 2, and the use function of the mechanism is further increased.
It is to be understood that the foregoing examples merely represent preferred embodiments of the present invention, and that the description thereof is more specific and detailed, but not intended to limit the scope of the invention; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
