[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] Example 1: This example provides an auxiliary device for straightening reinforcing bars, such as... Figure 1 As shown, it includes a bracket 1 and a first guide wheel 2. The bracket 1 is used to be installed at the feed inlet of the straightening and cutting machine. The first guide wheel 2 is rotatably mounted on the bracket 1, and a first rebar limiting groove 3 is provided on the side wall of the first guide wheel 2. The first rebar limiting groove 3 is arranged around the axis of the first guide wheel 2.
[0020] For example, in implementation, the bracket 1 is vertically arranged, the first guide wheel 2 is mounted on the bracket 1, and the first guide wheel 2 is rotatably connected to the upper end face of the bracket 1. The first rotating shaft can be connected to the upper end face of the bracket 1 by welding, shaft holes, bearings, etc., and the first guide wheel 2 can be connected to the upper end of the first rotating shaft by shaft holes, bearings, etc., thus achieving the purpose of rotatably connecting the first guide wheel 2 to the upper end of the bracket 1. A first reinforcing bar limiting groove 3 is formed on the side wall of the first guide wheel 2. The first reinforcing bar limiting groove 3 has an annular structure and is arranged around the axis of the first guide wheel 2.
[0021] During use, the bracket 1 is first installed at the feed inlet of the straightening and cutting machine, aligning the opening of the first rebar limiting groove 3 with the feed inlet of the straightening and cutting machine. Next, one end of the rebar is guided into the straightening and cutting machine via the first guide wheel 2, fitting into the first rebar limiting groove 3 on the first guide wheel 2. When the rebar moves along the first guide wheel 2 towards the straightening and cutting machine under the traction force of the straightening and cutting machine's traction mechanism, the first guide wheel 2 rotates. At this time, the rebar adheres to the groove wall, bottom, and other positions of the first rebar limiting groove 3. This aims to limit and guide the rebar, thereby reducing the risk of large swings, tangling, and knots during traction, improving the stability of rebar conveying, and reducing the difficulty of straightening work.
[0022] In a preferred embodiment, the longitudinal cross-sectional area of the first rebar limiting groove 3 gradually decreases from the opening of the first rebar limiting groove 3 towards the bottom of the first rebar limiting groove 3. This is intended to facilitate the placement of the rebar into the first rebar limiting groove 3.
[0023] Example 2: Based on Example 1 above, in this example, as follows... Figure 1 As shown, the auxiliary device also includes a guide post 4; the guide post 4 is disposed on the bracket 1; the guide post 4 is located on the feeding side of the first guide wheel 2; a rebar limiting hole 5 is provided on the guide post 4; the rebar limiting hole 5 corresponds to the first rebar limiting groove 3.
[0024] For example, in the implementation process, the auxiliary device also includes a guide post 4, which is connected to the upper end face of the bracket 1 by welding, screwing, or other means, and the guide post 4 is installed on the feeding side of the first guide wheel 2. A rebar positioning hole is provided on the guide post 4, which extends along the conveying direction of the rebar (along the direction from the first guide wheel 2 to the straightening and cutting machine).
[0025] During use, one end of the reinforcing bar is inserted into the reinforcing bar positioning hole to achieve preliminary positioning and guidance of the reinforcing bar before it enters the first guide wheel 2. This aims to further reduce the risk of the reinforcing bar swinging, tangling, or knotting during the traction process, thereby improving the stability of reinforcing bar conveying and reducing the difficulty of straightening work.
[0026] Furthermore, the rebar positioning hole corresponds to the groove opening of the first rebar limiting groove 3. This is intended to ensure that the rebar, after passing through the rebar positioning hole, can smoothly transition into the first rebar limiting groove 3 on the first guide wheel 2.
[0027] In one optional implementation, two guide posts 4 are provided, one on the feed side and the other on the discharge side of the first guide post 4. This aims to ensure that when the rebar enters / exits the first rebar limiting groove 3 on the first guide wheel 2, it can be positioned and guided through the rebar limiting hole 5 on the corresponding guide post 4. This reduces the risk of large swings, entanglement, and knots in the rebar during traction, thereby improving the stability of rebar conveying and reducing the difficulty of straightening work.
[0028] Example 3: Based on Example 2 above, in this example, the longitudinal cross-sectional area of the rebar limiting hole 5 gradually decreases along the rebar conveying direction.
[0029] For example, during implementation, the longitudinal cross-sectional area of the aforementioned rebar limiting hole 5 gradually decreases along the rebar conveying direction. That is, the end of the rebar limiting hole 5 with the larger diameter faces the direction of rebar feeding.
[0030] During use, one end of the reinforcing bar is inserted into the reinforcing bar limiting hole 5 from the end with the larger diameter. This is to facilitate the insertion of the reinforcing bar into the reinforcing bar limiting hole 5.
[0031] Example 4: Based on Example 1 above, in this example, as... Figure 1 As shown, the auxiliary device also includes a second guide wheel 6; the second guide wheel 6 is rotatably mounted on the bracket 1, and the second guide wheel 6 is positioned opposite to the opening of the first rebar limiting groove 3.
[0032] For example, in implementation, the auxiliary device further includes a second guide wheel 6. The second guide wheel 6 is mounted on the bracket 1 and rotatably connected to the upper end face of the bracket 1. The second guide wheel 6 can be rotatably connected to the upper end of the bracket 1 by connecting a second rotating shaft to the upper end face of the bracket 1 via welding, shaft holes, bearings, etc., and then connecting the second guide wheel 6 to the upper end of the second rotating shaft via shaft holes, bearings, etc. The second guide wheel 6 is arranged parallel to the first guide wheel 2, and the second guide wheel 6 is located in the groove of the first reinforcing bar limiting groove 3 on the first guide wheel 2.
[0033] A gap is provided between the second guide wheel 6 and the first guide wheel 2. During the rebar conveying process, this gap is used to reduce friction between the rotation of the second guide wheel 6 and the first guide wheel 2. This gap is smaller than the diameter of the rebar, aiming to reduce the risk of the rebar slipping out through the gap between the second guide wheel 6 and the first guide wheel 2.
[0034] During use, one end of the reinforcing bar is guided through the reinforcing bar limiting hole 5 on the guide post 4 into the first reinforcing bar limiting groove 3 on the first guide wheel 2, and the reinforcing bar is positioned between the second guide wheel 6 and the first reinforcing bar limiting groove 3. This is intended to reduce the risk of the reinforcing bar detaching from the first limiting groove.
[0035] Example 5: Based on Example 4 above, in this example, as... Figure 1 As shown, a second reinforcing bar limiting groove 7 is provided on the side wall of the second guide wheel 6; the second reinforcing bar limiting groove 7 is arranged around the axis of the second guide wheel 6, and the groove opening of the second reinforcing bar limiting groove 7 corresponds to the groove opening of the first reinforcing bar limiting groove 3.
[0036] For example, during implementation, a second reinforcing bar limiting groove 7 is provided on the side wall of the second guide wheel 6. The second reinforcing bar limiting groove 7 has an annular structure and is arranged around the axis of the second guide wheel 6. The opening of the second reinforcing bar limiting groove 7 is directly opposite the first reinforcing bar limiting groove 3.
[0037] During use, the steel bars can swing between the first steel bar limiting groove 3 and the second steel bar limiting groove 7 during the steel bar conveying process, in order to better adapt to the vibration and impact of the steel bars, thereby ensuring that the steel bars can be continuously and stably conveyed forward.
[0038] In one optional implementation, the longitudinal cross-sectional area of the second rebar limiting groove 7 gradually decreases from the opening of the groove towards the bottom. This is intended to facilitate the sliding of the rebar into the second rebar limiting groove 7.
[0039] Example 6: Based on Example 5 above, in this example, as... Figure 1 As shown, there are several second guide wheels 6, and these several second guide wheels 6 are arranged sequentially along the direction of steel bar conveying.
[0040] For example, in implementation, a plurality of the aforementioned second guide wheels 6 are provided, and these plurality of second guide wheels 6 are arranged sequentially along the direction of rebar conveying. This allows for adaptation to vibrations, impacts, and other conditions of the rebar at multiple positions along the rebar conveying direction, aiming to further ensure the continuous and stable forward conveying of the rebar.
[0041] Example 7: When the reinforcing bar passes the first guide wheel 2, the oxide layer, dust, and other impurities on the reinforcing bar will fall onto the upper surface of the support 1 under the action of vibration. Therefore, in order to reduce the risk of oxide layer, dust, and other impurities accumulating on the upper surface of the support 1, based on Example 1 above, in this example, as... Figure 1 As shown, a funnel 8 is provided on the support 1; the inlet of the funnel 8 is located below the first steel bar limiting groove 3.
[0042] For example, in implementation, the auxiliary device also includes a funnel 8. The funnel 8 is connected to the bracket 1 by welding, screwing, or integral molding, and the inlet of the funnel 8 is located below the first guide wheel 2. The aim is to effectively collect oxide layers, dust, and other impurities that fall off the reinforcing bars during the straightening process through the funnel 8, thereby reducing the risk of oxide layer and dust accumulation and improving the cleanliness of the auxiliary device.
[0043] Example 8: Based on Example 7 above, in this example, as... Figure 1 As shown, a material collection trough 9 is provided on the upper end face of the bracket 1; the inlet of the first guide wheel 2 and the funnel 8 are both located at the bottom of the material collection trough 9.
[0044] For example, in the implementation process, a collection trough 9 is provided on the upper end face of the aforementioned support 1, and the inlets of the aforementioned first guide wheel 2 and funnel 8 are both located at the bottom of the collection trough 9. The collection trough 9 can collect oxide layers, dust, and other impurities that fall off during the straightening of the reinforcing bars, and further collect them through the funnel 8. This aims to reduce the risk of oxide layers, dust, and other impurities falling off during the straightening of the reinforcing bars sliding off the upper end face of the support 1, thereby improving the cleanliness of the area near the support 1.
