Description

Technical Field

[0001] The invention relates to the technical field of steel bar processing, in particular to a steel bar straightening auxiliary device. Background Art

[0002] In the field of construction engineering, round and spiral coils are a common form of steel bars. In order to meet construction needs, round and spiral coils usually need to be straightened before use, that is, the curled steel bars are straightened through a steel bar straightening machine.

[0003] Traditional steel bar straightening machines often lack effective protective devices when straightening round and spiral steel bars. Since round and spiral steel bars are in a curled state before straightening, a large amount of elastic potential energy is stored inside them. When the steel bars are fed into the straightening machine for stretching, these potential energies will be released quickly, causing the steel bars to swing back and forth during the straightening process. It is very easy for the steel bars to be entangled with other external objects or hit the operators, posing a serious safety hazard. In addition, during the storage and transportation of round and spiral steel bars, a certain amount of rust will inevitably adhere to the surface. This rust will fall off and form rust residue during the steel bar straightening process. The falling of rust residue will not only pollute the cleanliness and working environment of the steel bar straightening machine, but more importantly, the rust residue may adhere to the straightening wheel, affecting the normal operation and straightening effect of the straightening wheel. When the rust residue accumulates to a certain extent, it will cause the straightening wheel to wear more severely and even cause mechanical failure, seriously affecting the quality and efficiency of steel bar straightening.

[0004] Therefore, the present invention proposes a steel bar straightening auxiliary device to solve the above problems. Summary of the invention

[0005] The embodiment of the present invention aims to provide a steel bar straightening auxiliary device to solve the above-mentioned problem.

Detailed Embodiments

[0028] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] See also Figures 1 to 3 A steel bar straightening auxiliary device comprises a protective cylinder 1 and a rust removal mechanism arranged in the protective cylinder 1 for removing rust from the steel bars, the rust removal mechanism comprises a sliding base 2 and a slide 3 arranged on the base 2 for sliding up and down, a rust removal cylinder 6 is rotatably provided on the slide 3, and steel bristles 7 are evenly distributed in the rust removal cylinder 6. When in use, one end of the protective cylinder 1 is connected to the inlet end of the steel bar straightening machine, and the round / spiral steel bars pass through the inside of the protective cylinder 1 and the rust removal cylinder 6 to enter the steel bar straightening machine for straightening.

[0030] It should be noted that when the rebar straightening machine pulls the feed, the rebar swings in the protective tube 1, and the sliding base 2 and the slide 3 will adaptively slide accordingly with the swing of the rebar, that is, the base 2 and the slide 3 are respectively in a lateral reciprocating sliding state and an up and down reciprocating sliding state driven by the swing of the rebar.

[0031] During the straightening of the coiled / spiral steel bars, the protective cylinder 1 is used to restrict the coiled / spiral steel bars so that they can only swing within a limited range in the protective cylinder 1. The protective cylinder 1 plays an isolating role, thereby preventing the steel bars from being entangled with other external objects or hitting the operator, greatly improving the safety of the straightening operation of the coiled / spiral steel bars; the coiled / spiral steel bars pass through the rust removal cylinder 6, and when the steel bar straightening machine pulls the feed, the rust on the surface of the steel bars is brushed off by the steel bristles 7, thereby achieving rust removal before entering the straightening machine, preventing rust residue from contaminating the straightening machine body and adhering to the straightening wheel, thereby ensuring the normal operation of the straightening wheel and the straightening effect, thereby ensuring the quality and efficiency of the steel bar straightening.

[0032] Furthermore, the protective tube 1 is funnel-shaped.

[0033] See also Figure 2 In one embodiment of the present invention, a plurality of support rods 4 are provided in the protective tube 1, and the support rods 4 slide through the base 2. The base 2 is supported by the plurality of support rods 4 so that it can slide back and forth laterally adaptively with the swing of the steel bars.

[0034] See also Figure 2 and Figure 4 In one embodiment of the present invention, the base 2 is provided with a slide groove 12 from top to bottom and adapted to the slide seat 3, the slide seat 3 is arranged in the slide groove 12, and the sliding structure can be set as a damping sliding structure;

[0035] A first rack 10 is provided on the base 2 from top to bottom, and a gear ring 9 meshing with the first rack 10 is sleeved on the rust removal cylinder 6.

[0036] In this embodiment, the sliding seat 3 is driven to reciprocate up and down along the sliding groove 12 as the steel bar is fed. Under the meshing drive of the gear ring 9 and the first rack 10, when the sliding seat 3 reciprocates up and down, it synchronously drives the rust removal cylinder 6 to rotate, so that the steel bristles 7 in the rust removal cylinder 6 brush around the steel bar, thereby realizing the removal of rust on the surface of the steel bar.

[0037] Furthermore, in this embodiment, slag discharge holes 11 for discharging rust slag are evenly distributed on the wall of the rust removal cylinder 6, and the rust slag brushed off is discharged through the slag discharge holes 11 to prevent accumulation in the rust removal cylinder 6 and affect the rust removal effect.

[0038] Please refer to Figure 2 and Figure 5 , in an embodiment of the present invention, the rust removal mechanism further includes a rust collection assembly 5 for collecting rust slag. The rust collection assembly 5 includes a first mounting boss 505 provided on the base 2 and a first rotating shaft 501 rotatably penetrating through the first mounting boss 505. The first rotating shaft 501 is located above the rust removal cylinder 6, and fan blades 502 are circumferentially and evenly arranged on the first rotating shaft 501. A collection tray 503 for receiving rust slag is detachably provided on the base 2. The collection tray 503 is located below the rust removal cylinder 6. A magnet 504 is further provided at a position below the collection tray 503 on the base 2, and the rust slag in the collection tray 503 is fixed by the magnetic attraction of the magnet 504.

[0039] Still further, in this embodiment, the rust collection assembly 5 further includes a second rotating shaft 506 and a second rack 510 provided on the base 2. Both ends of the second rack 510 are fixed to the wall of the protection cylinder 1. A first bevel gear 508 and a flat gear 507 meshing with the second rack 510 are provided on the second rotating shaft 506. A second bevel gear 509 meshing with the first bevel gear 508 is provided on the first rotating shaft 501;

[0040] The base 2 makes a reciprocating lateral slide driven by the swing of the steel bar. Under the meshing drive of the spur gear 507 and the second rack 510, when the base 2 makes a reciprocating lateral slide, it drives the second rotating shaft 506 to rotate, that is, drives the first bevel gear 508 to rotate. Under the meshing drive of the first bevel gear 508 and the second bevel gear 509, the rotation of the first bevel gear 508 drives the first rotating shaft 501 to rotate, and the rotation of the first rotating shaft 501 drives a plurality of fan blades 502 to revolve, so as to generate a downward air flow (a differential drive is provided between the first bevel gear 508 and the second bevel gear 509 to increase the rotation speed of the first rotating shaft 501 and ensure that sufficient air flow intensity can be generated when the fan blades 502 rotate). After the rust slag is discharged through the slag discharge hole 11, a part of it is in powder form (rust powder) and is easy to disperse. The downward air flow promotes the discharged rust powder to fall downward into the collection tray 503 for collection. The magnetic attraction effect generated by the magnet 504 causes the rust powder and the rust slag to be adsorbed in the collection tray 503, and there will be no phenomenon of rust slag falling and rust powder rising along with the reciprocating slide of the base 2, ensuring the full collection of rust slag. It should be noted that the magnet 504 is in the shape of a flat plate and is arranged below the collection tray 503, and the bottom of the collection tray 503 is made of non-magnetic isolation material, so that the magnet 504 can adsorb and fix the rust slag and the rust powder through the bottom of the collection tray 503. In addition, the collection tray 304 is detachably arranged on the base 2 by means of buckles, pins, etc., and the rust slag in the collection tray 503 is cleaned by removing the collection tray 503.

[0041] Further, in this embodiment, a wind guide cover (not shown in the figure) can be arranged outside the first rotating shaft 501 and the fan blades 502. The upper side of the wind cover is provided with an air inlet, and the lower side is provided with an air outlet, so as to guide the air flow to concentrate downward and reduce the divergence of the air flow.

[0042] Please refer to Figure 2 、 Figure 3 and Figure 6, in an embodiment of the present invention, the rust removal mechanism further includes a knocking component 8 for vibrating the rust removal cylinder 6 to promote the discharge of rust slag. The knocking component 8 includes a second mounting boss 803 provided on the sliding seat 3, a rod 801 slidably passing through the second mounting boss 803 (the cross-section of the rod 801 is non-circular to limit the rotation of the rod 801), and a mounting strip 806 provided on the base 2. One end of the rod 801 opposite to the rust removal cylinder 6 is provided with a knocking ball 802, and the other end is provided with a roller 805. A plurality of elastic members 804 are further provided between the rod 801 and the second mounting boss 803 (the elastic members 804 are springs, rubber elastic cords, etc. in the prior art, and are not limited in this embodiment). The roller 805 abuts against the mounting strip 806. A plurality of pushing pieces 807 that can deflect up and down by a certain angle are equidistantly hinged on the mounting strip 806 from top to bottom. When the pushing piece 807 deflects to the upper / lower limit angle, the vertical distance (as shown by d in the attachment) between the pushing piece 807 and the adjacent pushing piece 807 is greater than the outer diameter of the roller 805. It should be noted that the upper / lower limit angle of the pushing piece 807 refers to: taking the horizontal state of the pushing piece 807 as an example, the pushing piece 807 can only deflect up and down by a certain angle, such as 30°, 40°, etc. The mounting strip 806 is provided with a limiting measure corresponding to each pushing piece 807. The limiting measure can be using a hinge at a specific angle, or blocking the pushing piece 807 by setting a limiting boss, etc., and is not limited in this embodiment. Figure 6 as shown by d in the attachment

[0043] In this embodiment, when the sliding seat 3 swings up and down reciprocally with the steel bar, the roller 805 contacts the pushing piece 807 and drives it to deflect upward or downward until it reaches the set limit angle. When the pushing piece 807 reaches the set limit angle, it will abut against the roller 805 and cause the rod 801 to move away from the mounting strip 806, that is, drive the knocking ball 802 away from the rust removal cylinder 6. During this process, several elastic members 804 are pulled and tightened. When the roller 805 disengages from the corresponding pushing piece 807, the rod 801 instantaneously resets under the elastic action of several elastic members 804, that is, drives the knocking ball 802 to instantaneously strike on the rust removal cylinder 6 to vibrate it, and at the same time drives the steel bristles 7 to vibrate. Through the vibration effect, the rust slag in the rust removal cylinder 6 is discharged in a timely and effective manner.

[0044] Further, in this embodiment, a torsion spring 808 is further provided at the hinge connection between the pushing piece 807 and the mounting strip 806. In the natural state, the pushing piece 807 is in a horizontal state. By setting the torsion spring 808, the pushing piece 807 automatically resets to the initial set position (i.e., the horizontal state) after disengaging from the roller 805.

[0045] Further, in this embodiment, the knocking ball 802 is made of rubber material to avoid knocking damage to the rust removal cylinder 6.

[0046] Finally, it should be noted that in this application, the swing generated when the coiled bar / coiled screw bar feeds into the steel bar straightening machine is used as the driving source, and the corresponding linkage structure is used to realize the rotation of the rust removal cylinder 6, the rotation of the first rotating shaft 502 to generate a downward air flow, and the knocking component 8 to knock the rust removal cylinder 6 to vibrate it. There is no need to separately set a driving part (such as a servo motor, a reduction motor, etc.), thereby reducing the manufacturing cost of this auxiliary device.

[0047] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
