Description

Technical Field

[0001] This utility model relates to the field of fastener processing technology, and in particular to a wire feeding frame that prevents raw materials from being scratched. Background Technology

[0002] In the production of fasteners such as nuts and bolts, raw steel bars are coiled on a vertical coiled wire frame, which is then placed on a rotatable wire frame base. During fastener processing, the raw steel bars can be pulled, causing the raw steel bars to drive the vertical coiled wire frame and the wire frame base to rotate, thereby releasing the wire.

[0003] Traditional wire feeding racks have revealed numerous problems in practical applications. For example, the original rack base limit posts are too low, resulting in a relatively high center of gravity and poor stability when the vertical coiled wire rack is too tall. If the wire feeding becomes obstructed, the rack is prone to tipping over. Furthermore, because the base is not secured, tipping over often causes the base to shift, potentially damaging the equipment and posing a safety hazard to operators.

[0004] Furthermore, for raw materials with a wire diameter of φ30 or larger, the increased tension generated by the machine during production significantly increases the friction between the raw material and the vertical coiled wire frame. Prolonged friction leads to wear on the wire frame surface, resulting in a rough and uneven surface that can scratch the raw material. Once the raw material surface is scratched, noticeable wire marks will remain after subsequent processing into the finished product. This not only affects the appearance quality of the finished product and reduces its market competitiveness, but may also negatively impact its physical properties, such as strength and corrosion resistance, causing serious damage to the overall quality of the product. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a wire feeding rack that prevents raw materials from being scratched, thus ensuring stable production.

[0006] Therefore, the technical solution of this utility model is: a wire feeding frame to prevent raw material scratches, comprising a wire frame base and a vertical coiled wire frame. The wire frame base includes a base plate, support columns, and a rotating frame. The support columns are fixed on the base plate, and the rotating frame is rotatably mounted on the support columns. The rotating frame includes multiple horizontally extended support arms, and vertically positioned limiting columns are provided near the center of the rotating frame on the support arms. The vertical coiled wire frame includes a base plate and multiple columns, and the base plate can be fitted onto the outside of the limiting columns. The top of the vertical coiled wire frame is provided with multiple outwardly extending mounting brackets. Guide rollers are rotatably mounted between the mounting brackets and the base plate, and the distance between the guide rollers and the center of the base plate is greater than the distance between the columns and the center of the base plate.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the guide roller is made of hard optical shaft and has a smooth surface.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the height of the limiting post is one-third to one-half of the height of the column.

[0009] Based on the above scheme and as a preferred option: a connecting rod is provided at the top of two adjacent limiting posts to connect the limiting posts into a polygonal prism structure.

[0010] Based on the above scheme and as a preferred option, a horizontal reinforcing rod is provided between any two limiting posts.

[0011] Based on the above solution and as a preferred solution: the base plate is provided with mounting holes and is fixed to the ground by expansion screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Based on the original wire frame structure, multiple vertical guide rollers were installed, so that the raw material first contacts the guide rollers during the wire feeding process. When the machine pulls the raw material, the guide rollers can reduce contact wear with the raw material by rotating themselves, ensuring that the surface of the raw material is not scratched during the wire feeding process, which greatly improves the surface quality of the finished product in subsequent processing.

[0014] The rotating frame features heightened limiting posts, and the traditional external clamping method has been replaced with internal support. This provides more reliable limiting support for the vertical coiled wire frame during rotation, ensuring that the wire frame does not tilt on the rotating frame. The height of the limiting posts is designed to prevent excessive height from affecting the operation of the wire frame, while also greatly improving the stability of the wire frame within its effective range.

[0015] The base plate is fixed to the ground with expansion screws, which effectively prevents the base from shifting when the vertical coil wire rack tilts. At the same time, it allows all wire racks to be installed in the same position, ensuring that all wire racks are on the same horizontal line. This not only improves the overall aesthetics of the production site, but also facilitates the layout and management of production equipment, further optimizing the production environment.

[0023] In the description of this utility model, it should be noted that the directional terms such as "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0025] See the attached drawings. The wire feeding rack for preventing raw material scratches described in this embodiment includes a wire rack base 1 and a vertical coiled wire rack 2. The wire rack base 1 includes a base plate 11, support columns 12, and a rotating frame 13. The base plate 11 is a square steel plate structure with mounting holes, allowing it to be fixed to the ground using expansion screws 3. Multiple wire feeding racks can be installed on the same horizontal line within the factory, improving the overall aesthetics of the production area.

[0026] The support column 12 is fixed to the base plate 11, and the two can be welded together. The rotating frame 13 is rotatably mounted on the support column 12 at its center via a bearing, allowing the rotating frame 13 to rotate relative to the support column 12. Six horizontally extending support arms 14 are evenly distributed on the rotating frame 13, and vertically positioned limiting columns 15 are provided near the center of the rotating frame on each support arm 14. Connecting rods 16 are provided at the top of adjacent limiting columns 15, connecting the limiting columns 15 into a polygonal prism structure. A transverse reinforcing rod 17 can be added in the middle as needed, connecting any two limiting columns 15 to increase the strength of the limiting columns 15 and prevent deformation of a single limiting column 15 under stress.

[0027] The vertical coiled wire frame 2 includes a base 21 and multiple uprights 22. The base 21 can be fitted onto the outside of the polygonal prism structure formed by the limiting posts 15, which prevent the vertical coiled wire frame 2 from tilting. Simultaneously, the height of the limiting posts 15 is extended to one-third to one-half the height of the uprights 22 on the vertical coiled wire frame. A height exceeding one-third of the height of the uprights 22 allows the limiting posts 15 to better support the vertical coiled wire frame 2, preventing it from tipping over during operation. A height below half the height of the uprights 22 avoids interfering with the normal operation of the vertical coiled wire frame 2. This height setting of the limiting posts avoids affecting the operation of the wire frame due to excessive height and greatly improves the stability of the wire frame within an effective range.

[0028] The vertical coiled wire frame 2 has an outwardly extending mounting bracket 23 at its top. Multiple vertical guide rollers 24 are rotatably mounted between the mounting bracket 23 and the base 21. The distance between the guide rollers 24 and the center of the base 21 is greater than the distance between the column 22 and the center of the base 21, meaning the guide rollers 24 are located on the outer ring. When the reinforcing bar 4 is wound around the vertical coiled wire frame 2, it comes into contact with the guide rollers 24. The guide rollers 24 are made of hard, smooth material with high hardness and are not easily worn. Rotation reduces contact wear on the reinforcing bar, preventing scratches and improving product quality.

[0029] During installation, the base plate of the wire frame base 1 is fixed to the ground with expansion bolts. The coiled steel bars are then fitted onto the vertical coiled wire frame 2. A crane is used to lift the vertical coiled wire frame 2 onto the wire frame base 1, aligning it with the polygonal prism structure formed by the limiting posts and lowering it to fit onto the outside of the polygonal prism structure. The head of the steel bar is then pulled out and fed into the fastener processing equipment. During processing, the steel bar is pulled by the fastener processing equipment, causing the vertical coiled wire frame 2 and the rotating frame 13 to rotate and release the material. During the pulling process, the steel bar comes into contact with the guide roller 24 of the vertical coiled wire frame 2. The guide roller 24 can reduce the force by rotating, avoiding scratching the steel bar and improving the quality of the fasteners processed subsequently.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
