Description

Technical Field

[0001] The utility model relates to the field of steel turning devices, in particular to a steel turning device for producing ribbed steel bars. Background Art

[0002] Cold-rolled ribbed steel bars are two-sided or three-sided crescent-shaped steel bars that are formed by multiple cold-rolling of hot-rolled wire rods to reduce diameter, compress ribs and eliminate internal stress. This type of steel bar is an updated product of cold-drawn low-carbon steel wire in prestressed concrete components, and can replace Grade I steel bars in cast-in-place concrete structures to save steel. It is a better type of cold-processed steel. Its production process requires a series of equipment, among which the steel turning device is a key equipment to ensure that the steel bars are smoothly turned, sorted and transported to the next process.

[0003] Existing steel turning devices are usually only set to turn the steel once, and the height and width of the steel bars are relatively limited. In addition, turning the steel once can easily affect the accuracy of steel bar collection. One turning of the steel may not achieve the expected effect, and the operator may need to take additional measures or manually adjust the position of the steel bars, thereby increasing the complexity and difficulty of the operation.

[0004] The existing patent application number is CN201610503441.2, which is a high-ductility cold-rolled ribbed steel bar production line. After the steel bar wire is cut, it is conveyed in the feed chute trough. The steel fork uses the steel turning axis as the rotation center. The steel fork pulls the steel bar out of the feed chute trough. After being pulled out by the steel fork, the steel bar is brought to the steel pushing device and transported to the material receiving trolley by the conveyor roller. However, in this scheme, after the steel bar falls off the steel turning fork, it is easy to cause the steel bar to shift due to the influence of gravity, affecting the accuracy of steel bar collection, and then affecting the subsequent processing and product quality of the steel bar.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0034] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0035] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0036] The utility model provides a steel turning device for producing ribbed steel bars, such as Figures 1 to 6 As shown, it includes a conveying mechanism 1, a primary steel turning mechanism 2, and a secondary steel turning mechanism 3.

[0037] In this embodiment, the conveying mechanism 1 includes a conveying track 11 and a conveying wheel 12. The conveying wheel 12 is used to drive the steel bars to move along the conveying track 11. A limit baffle 13 corresponding to the conveying track 11 is arranged at one end of the conveying track 11. The conveying track 11 includes multiple groups, and there is a gap between two adjacent conveying tracks 11. The conveying wheel 12 is located in the gap.

[0038] In this embodiment, the conveying mechanism 1 further includes a first drive motor 14 for driving the conveying wheel 12 to rotate. The driving end of the first drive motor 14 is linked to the conveying wheel 12 , and the axial direction of the conveying wheel 12 is perpendicular to the central axis of the conveying track 11 .

[0039] In this embodiment, when the first drive motor 14 is started, its power is transmitted to the conveying wheel 12 through a linkage connection, causing the conveying wheel 12 to start rotating. The rotating conveying wheel 12 contacts the steel bars and pushes the steel bars forward along the conveying track 11 through friction. The steel bars continue to move forward under the action of the conveying wheel 12 until they contact the limit baffle 13.

[0040] In this embodiment, a tail-off switch 15 is provided at one end of the conveying track 11 away from the limit baffle 13 , and the tail-off switch 15 is used to detect whether the steel bar has completely entered the conveying track 11 .

[0041] In this embodiment, the conveying track 11 is arranged to be a V-shaped structure. The conveying track 11 has a shape structure in which the edges on both sides are inclined upward and the middle is concave, so that the conveying track 11 has specific guiding and supporting properties in the cross section, which helps to ensure the stability and accuracy of the steel bars during the conveying process, and can still provide sufficient supporting force to withstand the weight of the steel bars and the impact force during the movement.

[0042] In this embodiment, the primary steel turning mechanism 2 includes a primary steel turning transmission shaft 21 and a primary steel turning plate 22 located on the primary steel turning transmission shaft 21. The primary steel turning plate 22 corresponds to the gap between two adjacent conveying rails 11. The primary steel turning plate 22 rotates synchronously with the primary steel turning transmission shaft 21. The primary steel turning plate 22 is provided with a hooking portion 221 for hooking the steel bars on the conveying rail 11. In this embodiment, the primary steel turning mechanism 2 also includes a second driving motor 23 for driving the primary steel turning transmission shaft 21 to rotate.

[0043] In this embodiment, when the steel bar completely enters the conveying track 11, the second drive motor 23 is started, and the first steel turning plate 22 starts to rotate under the drive of the transmission shaft. The hooking portion 221 on the rotating first steel turning plate 22 contacts the steel bar and hooks it from the conveying track 11. The steel bar rotates with the first steel turning plate 22. After reaching a predetermined flipping angle, the hooking portion 221 releases the steel bar, allowing it to continue to move along the production line or enter the next processing link.

[0044] In this embodiment, the primary steel turning plate 22 also includes a limiting portion 222 and a connecting portion 223. The connecting portion 223 is located between the limiting portion 222 and the hooking portion 221. The limiting portion 222 corresponds to the receiving portion 321 on the secondary steel turning plate 32. The hooking portion 221, the limiting portion 222 and the connecting portion 223 work together in the primary steel turning plate 22 to jointly complete the hooking, flipping and positioning of the steel bars. The setting of the limiting portion 222 can ensure the position accuracy of the steel bars during the steel turning process. When the steel bars are hooked and rotated to a predetermined position with the steel turning plate, the limiting portion 222 will limit the further movement of the steel bars so that they can accurately fall into the receiving portion 321 on the secondary steel turning plate 32 (as described below). The connecting portion 223 is located between the limiting portion 222 and the hooking portion 221, and plays a role of connection, support and guidance. The steel bars slide from the hooking portion 221 to the limiting portion 222 along the connecting portion 223.

[0045] In the present embodiment, the single-turn steel plate 22 is integrally formed and has a triangular structure. The connecting portion 223, the limiting portion 222 and the hooking portion 221 on the single-turn steel plate 22 include three groups, and the three groups of the hooking portion 221, the connecting portion 223 and the limiting portion 222 are arranged in sequence along the triangular structure. The hooking portion 221 and the limiting portion 222 in two adjacent groups of the hooking portion 221, the connecting portion 223 and the limiting portion 222 are fixedly connected to form three independent turning units, so that the single-turn steel plate 22 can continuously turn over the steel bars by continuous rotation, thereby improving production efficiency.

[0046] In this embodiment, the secondary steel turning mechanism 3 includes a secondary steel turning transmission shaft 31, a secondary steel turning plate 32 located on the secondary steel turning transmission shaft 31, and the secondary steel turning plate 32 rotates synchronously with the secondary steel turning transmission shaft 31; the secondary steel turning plate 32 is provided with a receiving portion 321 for receiving the steel bar, and the receiving portion 321 is used to quickly and accurately capture the steel bar and stabilize it on the secondary steel turning plate 32. When the primary steel turning mechanism 2 or other conveying equipment transmits the steel bar to the position of the secondary steel turning mechanism 3, the steel bar is first captured and stably carried by the receiving portion 321 on the secondary steel turning plate 32. Subsequently, as the secondary steel turning transmission shaft 31 rotates, the secondary steel turning plate 32 drives the steel bar to rotate together and transmits it according to a predetermined path and speed. In this embodiment, the receiving portion 321 is provided with a U-shaped groove for clamping the steel bar to ensure the stability of the steel bar when the secondary steel turning plate 32 drives the steel bar to rotate together.

[0047] In this embodiment, the receiving part 321 on the secondary steel turning plate 32 includes two groups, and the two groups of receiving parts 321 are distributed on both sides of the secondary steel turning plate 32, and the two groups of receiving parts 321 are symmetrical about the center, so that the secondary steel turning plate 32 can continuously rotate to continuously turn over the steel bars. In other embodiments, the receiving part 321 on the secondary steel turning plate 32 may also include multiple groups, and the multiple groups of receiving parts 321 are evenly distributed along the circumferential direction, so that the secondary steel turning plate 32 can continuously rotate to continuously turn over the steel bars.

[0048] In this embodiment, the outer wall of the secondary steel turning transmission shaft 31 is sleeved with a secondary steel turning synchronous pulley 33, and the secondary steel turning mechanism 3 also includes a rotating motor 331, and the driving end of the rotating motor 331 is sleeved with a transmission belt 332, and the transmission belt 332 is sleeved on the outer wall of the secondary steel turning synchronous pulley 33, and the driving end of the rotating motor 331 drives the secondary steel turning synchronous pulley 33 to rotate through the transmission belt 332.

[0049] In this embodiment, when the rotating motor 331 is started, its driving end begins to rotate and transmits this rotational motion to the secondary steel-turning synchronous pulley 33 through the transmission belt 332. Since there is friction and meshing between the transmission belt 332 and the two wheels (the driving wheel of the motor and the secondary steel-turning synchronous pulley 33), the rotation of the motor driving end will drive the transmission belt 332 and the secondary steel-turning synchronous pulley 33 to rotate together, thereby realizing the secondary steel-turning drive shaft 31 (and other mechanical components connected thereto) also moving with the rotation of the secondary steel-turning synchronous pulley 33, thereby realizing the functions required by the secondary steel-turning mechanism 3.

[0050] In this embodiment, a sliding steel guide 4 is arranged between the primary steel turning mechanism 2 and the secondary steel turning mechanism 3. The steel bars on the conveying track 11 pass through the conveying track 11, the hooking portion 221 on the primary steel turning plate 22, and the sliding steel guide 4 in sequence, and then fall into the receiving portion 321 on the secondary steel turning plate 32. In this embodiment, the setting of the sliding steel guide 4 ensures that the steel bars can move along a predetermined path and posture during the process of transferring from the primary steel turning plate 22 to the secondary steel turning plate 32, avoiding deviation or collision, and can effectively reduce the shaking and vibration of the steel bars during the transfer process, thereby ensuring the smooth transfer of the steel bars.

[0051] In this embodiment, the sliding steel guide 4 includes a support portion 41 and a guide portion 42. The guide portion 42 is located at the top of the support portion 41, so that the sliding steel guide 4 is in a T-shaped structure. The end surface of the guide portion 42 away from the support portion 41 is set as an inclined structure. The length of the guide portion 42 is greater than the interval length between the primary steel turning transmission shaft 21 and the secondary steel turning transmission shaft 31. In this embodiment, the device also includes a frame 5. Based on the frame 5, the height of the primary steel turning mechanism 2 is higher than the height of the secondary steel turning mechanism 3, the height of the primary transmission shaft is higher than the height of the secondary steel turning transmission shaft 31, and the diameter of the primary steel turning plate 22 is greater than the diameter of the secondary steel turning plate 32.

[0052] In this embodiment, the support part 41 serves as the base part of the guide member. The support part 41 is responsible for being firmly mounted on the frame 5 to provide support for the entire guide member. The main function of the guide part 42 is to guide the steel to slide along a predetermined path to ensure stability and directionality during the steel turning process. The inclined structure helps the steel to transition more smoothly during the turning process, reduces friction and resistance, and also helps to adjust the positioning of the steel before and after the turning. The length of the guide part 42 is greater than the interval length between the primary steel turning transmission shaft 21 and the secondary steel turning transmission shaft 31, so that the guide part 42 can more effectively cover and guide the movement of the steel between the two steel turning transmission shafts to ensure the continuity and stability of the steel turning action; the primary steel turning mechanism 2 The height difference between the primary steel turning mechanism and the secondary steel turning mechanism 3 is beneficial to the gravity assistance of the steel during the flipping process, so that the steel can transition more naturally from one steel turning mechanism to another; the height of the primary transmission shaft is also higher than the secondary steel turning transmission shaft 31, and the diameter of the primary steel turning disk 22 is larger than the diameter of the secondary steel turning disk 32. This gradient change in design not only conforms to the physical laws in the steel flipping process, but also can provide different flipping support for the steel at different stages. The larger steel flipping disk diameter can provide a larger support area and flipping torque during the initial flipping, ensuring that the steel can flip smoothly, while the smaller steel flipping disk diameter can reduce resistance in subsequent flipping, making the flipping action faster and more flexible.

[0053] In this embodiment, a primary steel turning zero position detection component 24 is provided at one end of the primary steel turning transmission shaft 21, and the primary steel turning zero position detection component 24 rotates synchronously with the primary steel turning transmission shaft 21, and a primary steel turning zero position switch 25 is provided on one side of the primary steel turning zero position detection component 24, and the primary steel turning zero position switch 25 is installed on the frame 5, for detecting that the primary steel turning plate 22 is at the working origin position, waiting for flipping and steel feeding; a secondary steel turning zero position detection component 34 is provided at one end of the secondary steel turning transmission shaft 31, and the secondary steel turning transmission shaft 31 rotates synchronously with the secondary steel turning zero position detection component 34, and a secondary steel turning zero position switch 35 is provided on one side of the secondary steel turning zero position detection component 34, and the secondary steel turning zero position switch 35 is installed on the frame 5, for detecting that the secondary steel turning plate 32 is at the working origin position, waiting for flipping and steel feeding.

[0054] The utility model provides a steel turning device for producing ribbed steel bars. When the steel bars completely enter the conveying track 11, they are hooked by the hooking portion 221 on the primary steel turning plate 22 and rotate with the primary steel turning plate 22. After rotating to a certain angle, the steel bars are released from the hooking portion 221 and slide along the sliding steel guide 4. The steel bars slide to the receiving portion 321 on the secondary steel turning plate 32, are stably received and continue to rotate with the steel turning plate for secondary turning. After the secondary turning, the steel bars can be conveyed to the next production link or subjected to other processing.
