Detailed Description

The invention discloses a bar and wire outlet guide, which not only plays a role in guiding, but also can clamp and centralize bar and wire, and eliminate the defect of free wide spreading surface 'ear' of the bar and wire.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a bar and wire outlet guide, which comprises: a guide, a guide roller 7 and a support frame 3. Wherein, a guide hole is arranged in the guide piece and is communicated with the hole of the roller 4. The roll 4 holes are formed by the rolls 4. The rod wire is rolled while passing through the hole of the rolling roller 4 and then leaves the rolling roller 4 under the guiding action of the guiding hole. The two guide rolls 7 form the micro-rolling holes. The micro-rolling hole is communicated with the guide hole. The rod and the wire enter the micro-rolling hole after being moved out of the guide hole. The rod wire is subjected to the micro-rolling force of the guide roller 7 while passing through the micro-rolling hole, thereby being straightened. The guide piece and the guide roller 7 are fixed on the support frame 3. The rod and wire outlet guide and guard provided by the invention not only can guide the rod and wire, but also can clamp and centralize the rod and wire material type, so that the defect of 'ear' of a free wide spreading surface is eliminated.

The guide roll 7 is described next: the distance between the two guide rollers 7 is adjustable. Therefore, the distance between the two guide rollers 7 can be adjusted according to the size of the specific bar and wire and the abrasion condition of the guide rollers 7, and the application range of the bar and wire outlet guide is widened. The specific adjustment principle is as follows: the guide roller shaft 8 of the guide roller 7 is driven by a drive. When the distance between the two guide rollers 7 needs to be reduced, the driving device drives the guide roller shaft 8 to be far away from the other guide roller shaft 8. When the distance between the two guide rollers 7 needs to be increased, the driving device drives the guide roller shaft 8 to be close to the other guide roller shaft 8.

The drive means may be a lead screw device. The screw device includes a rotating portion and a moving portion. The moving part is connected to the guide roller shaft 8. The moving part drives the guide roller shaft 8 to move away from or close to the guide roller shaft when moving back and forth.

The drive means may also be an eccentric shaft arrangement, in particular comprising a worm 6 and a gear eccentric sleeve 5. The worm 6 is meshed with the gear eccentric sleeve 5. The gear eccentric sleeve 5 is provided with an eccentric hole. The guide roller shaft 8 is arranged in the eccentric hole in a penetrating way. When the worm 6 drives the gear eccentric sleeve 5 to rotate, the gear eccentric sleeve 5 drives the guide roller shaft 8 to rotate. Since the guide roller shaft 8 is eccentrically provided with respect to the gear eccentric sleeve 5, the position of the guide roller shaft 8 in the radial direction changes. The guide roller 7 on the guide roller shaft 8 is changed. The two guide rollers 7 are arranged in the radial direction of the guide roller shaft 8, so that the gap between the two guide rollers 7 can be made larger or smaller.

It should be noted that the driving device may also be other mechanisms, such as a cylinder or a hydraulic device. The structure of the driving device is not particularly limited, and the driving device can adjust the gap between the two guide rollers 7 and falls into the protection scope of the present invention.

The guide roller 7 is preferably made of hard wear-resistant alloy. The guide rail made of the hard wear-resistant alloy has better surface smoothness. The guide roller 7 is beneficial to improving the surface smoothness of the bar wire after the bar wire is subjected to micro rolling.

Next, the guide 1 is described: the guide 1 is provided with a guide plate 2 at one end near the roller 4. The two guide plates 2 form a conical bore. The lower diameter end of the taper hole is communicated with the inlet of the guide hole. That is, the rod and wire rolled by the roller 4 first enters the taper hole, the inner diameter of the taper hole is gradually reduced, and the moving space of the rod and wire is gradually reduced, so that the rod and wire can be effectively centered with the downstream micro-rolling hole.

Further, the end of the guiding plate 2 close to the roll 4 is provided with a chamfer. The chamfer is matched with the hole groove of the roller 4, so that the front end of the guide plate 2 can be attached to the hole groove of the roller 4, the bar wire is effectively led out, and the bar wire is separated from the roller 4.

The guide member 1 is connected to the support frame 3 in the following way: a part of the guide 1 is inserted into the support frame 3. The front part of the guide 1, or the part of the guide 1 near the roll 4, extends outside the support frame 3. The fastening screw passes through the support frame 3 and the guide 1 in the radial direction, thereby locking the guide 1 to the support frame 3.

Further, the portion defining the guide 1 that protrudes outside the support frame 3 has a larger outer diameter than the portion located inside the support frame 3. Since the outer diameter of the portion extending outside the support frame 3 is sufficiently large, the partial guide 1 has a strong structural strength, thereby being capable of forming a strong guiding force for the bar wire. The guide member 1 inside the support frame 3 has a smaller outer diameter, so that the whole bar and wire outlet guide can be more compact.

The bar and wire exit guide is typically located on the mill roll 4 stand. In order to facilitate the adjustment of the position of the bar and wire outlet guide in the axial direction, in this embodiment, a guide cross beam is provided on the stand of the roll 4, parallel to the roll 4. The base of the supporting frame 3 of the bar and wire outlet guide is fixed on the guide cross beam in a sliding way. Namely, the position of the bar and wire outlet guide can be adjusted by pushing the support frame 3 to move on the guide cross beam. After the proper position is adjusted, the support frame 3 is locked on the guide beam.
