Abstract
Description
Technical Field
[0001] This utility model relates to the field of reducing machine manufacturing technology, and in particular to a guide structure for a reducing machine and a reducing machine. Background Technology
[0002] A reducing mill is a piece of equipment used for processing metal materials. Its main function is to reduce and fix the diameter of metal billets to achieve specific dimensional accuracy and surface quality requirements. It typically applies pressure to the metal material through a die, causing plastic deformation and thus achieving precise dimensional control. This equipment is widely used in the production of metal products such as steel pipes and profiles, effectively improving product precision and quality to meet the needs of various fields. The setting of the reducing mill guide is crucial; it precisely guides the trajectory of the rolled piece as it leaves the reducing mill, preventing problems such as workpiece deviation, roll wrapping, or steel piling caused by high rolling speeds and tension variations, ensuring the workpiece can stably enter subsequent processing steps.
[0003] Currently, some reducing and setting machines have guides, including upper and lower guides. The upper and lower guides together form the red steel transmission channel and are arranged at the output end of the reducing and setting machine body. The opening and closing surfaces of the upper and lower guides are flat, and the closing surface forms a 45-degree angle with the base. This layout makes the reducing and setting machine guides very prone to misalignment. When the red steel comes into contact with the misaligned part, the surface will be squeezed with deep grooves, which will lead to quality defects such as deep scratches and folds in the finished product.
[0004] Therefore, there is an urgent need for a guide structure for reduction gears that can solve the problem of misalignment of the upper and lower guides in existing reduction gears. Utility Model Content
[0005] The purpose of this utility model is to provide a guide structure for a reduction setter, which can solve the problem of misalignment of the upper and lower guides in existing reduction setters, avoid the basic defects such as excessive ovality and surface scratches caused by guide misalignment, and thus avoid serious quality problems such as deep grooves, scribing and metal folding caused by uneven force.
[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0013] As an optional solution for the guide structure of the reducing machine, the feed end of the upper guide assembly and the feed end of the lower guide are covered to form a first feed port. The first feed port is an outwardly expanding horn-shaped opening, which narrows from the outside to the middle. The first feed port is located at the starting position of the red steel passage.
[0014] As an optional solution for the guide structure of the reducing machine, a first stabilizing member extends on both sides of the lower guide radially. The first stabilizing member extends along the movement direction of the red steel. A second stabilizing member is provided at the corresponding position of the upper guide assembly and the first stabilizing member. The first stabilizing member is provided with a first limiting member protruding at both the front and rear of the second stabilizing member. The first limiting member is used to limit the displacement of the second stabilizing member along the movement direction of the red steel.
[0015] As an optional solution for the guide structure of the reducing machine, the upper guide assembly includes a front guide and a rear guide. The rear guide is located downstream of the front guide. The inlet end of the front guide is aligned with the inlet end of the lower guide, and the outlet end of the rear guide is aligned with the outlet end of the lower guide. The front guide and the rear guide are spaced apart.
[0016] As an optional solution for the guide structure of the reducing machine, the feed end of the rear guide and the lower guide cover are combined to form an auxiliary guide port. The auxiliary guide port on the rear guide is an outward-expanding horn-shaped opening, which narrows from the outside to the middle. The auxiliary guide port is located in the middle of the red steel passage.
[0017] As an optional solution for the guide structure of the reducing machine, a first stabilizing member extends on both sides of the lower guide radially. The first stabilizing member extends along the movement direction of the red steel. A second stabilizing member is provided at the corresponding position of the upper guide assembly and the first stabilizing member. The first stabilizing member is provided with a first limiting member protruding at both the front and rear of the second stabilizing member. The first limiting member is used to limit the displacement of the second stabilizing member along the movement direction of the red steel. The second stabilizing member is provided on the front guide.
[0018] In the area corresponding to the rear guide, a third stabilizing member extends radially on both sides of the lower guide. The third stabilizing member extends along the movement direction of the red steel. A fourth stabilizing member is provided at the position corresponding to the third stabilizing member on the upper guide. The third stabilizing member has a second limiting member protruding in front of and behind the fourth stabilizing member. The second limiting member is used to limit the displacement of the fourth stabilizing member along the movement direction of the red steel.

[0021] The beneficial effects of this utility model are as follows:
[0022] This utility model proposes a guide structure for a reduction gear machine. The lower guide extends along the direction of movement of the red steel, and the upper guide assembly also extends along the direction of movement of the red steel. The upper guide assembly covers the lower guide, and the upper and lower guide assemblies together form a cylindrical red steel passageway. One of the discharge ends of the upper and lower guide assemblies protrudes towards the other, forming a convex part; the opposite end of the upper and lower guide assemblies is recessed at a corresponding point, forming a concave part. The concave and convex parts fit together, and the guide structure of the reduction gear machine achieves stable and precise positioning through the concave-convex fit of the upper and lower guide discharge ends, ensuring that the cylindrical red steel passageway remains in a fixed position and direction. This prevents the red steel from moving at high speeds. During the process, it can move stably along the preset trajectory, effectively avoiding the problem of trajectory deviation caused by guide swaying and misalignment, providing a stable foundation for the subsequent processing of the red steel. The passageway constrains the red steel from all sides, limiting its deformation space during movement. The convex and concave parts of the upper guide assembly and the lower guide discharge end cooperate to form a stable constraint on the shape of the red steel during passage. The precise positioning effect of the concave and convex structure ensures the shape accuracy of the columnar passageway, avoiding basic defects such as excessive ellipticity and surface scratches caused by guide misalignment, and thus avoiding serious quality problems such as deep grooves, scribing and metal folding caused by uneven force.

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0042] This embodiment provides a reducing and sizing machine applicable to the steel metallurgical industry for precise diameter reduction and sizing of steel to meet production needs. In this embodiment, the reducing and sizing machine includes the machine itself and a guide structure for the machine. The guide structure guides the movement trajectory of the hot steel and constrains and protects its shape. The guide structure is mounted on the machine body, with its inlet end connected to the outlet end. This ensures stable operation of the hot steel during transport, reducing production failures and product quality defects caused by trajectory deviation or shape damage. It also improves the precision and consistency of hot steel processing, ensuring the continuity and efficiency of the production process, thereby enhancing overall production quality and efficiency and reducing production costs.
[0043] This embodiment also provides a guide structure for a reducing mechanism, such as... Figures 1-4As shown, in this embodiment, the guide structure for the reduction setter includes a lower guide 1 and an upper guide assembly 2. The lower guide 1 extends along the direction of movement of the red steel, and the upper guide assembly 2 extends along the direction of movement of the red steel. The upper guide assembly 2 covers the lower guide 1, and the upper guide assembly 2 and the lower guide 1 are closed to form a cylindrical red steel passage channel 3. One of the discharge ends of the upper guide assembly 2 and the lower guide 1 protrudes towards the other to form a protrusion 221, and the other of the two protrusions is recessed at the corresponding position of the protrusion 221 to form a recess 11. The recess 11 and the protrusion 221 are in a concave-convex fit. The guide structure of the reduction setter forms a stable and precise positioning through the concave-convex fit of the discharge ends of the upper and lower guides 1, so that the cylindrical red steel passage channel 3 always remains in a fixed position. With a fixed position and direction, the red steel can move stably along a preset trajectory during high-speed movement, effectively avoiding trajectory deviation caused by guide swaying or misalignment. This provides a stable foundation for subsequent processing of the red steel. The passageway constrains the red steel from all sides, limiting its deformation space during movement. The convex part 221 and concave part 11 at the discharge end of the upper guide assembly 2 and the lower guide 1 engage in a convex-concave fit, providing stable constraint on the shape of the red steel during its passage. The precise positioning effect of the convex-concave structure ensures the shape accuracy of the cylindrical passageway, preventing guide misalignment that could lead to fundamental defects such as excessive ellipticity and surface scratches in the red steel. This, in turn, avoids serious quality problems such as deep grooves, scribing, and metal folding caused by uneven stress. The rigid convex-concave fit structure effectively buffers the lateral impact force during high-speed passage of the red steel, reducing the interference of guide deformation on the shape of the red steel. This protects the surface quality of the red steel and ensures the consistency of the red steel's cross-sectional dimensions through stable channel constraint, providing a qualified blank for subsequent processing.
[0044] Optionally, such as Figures 1-4 As shown, in this embodiment, the protrusion 221 is disposed on the upper guide assembly 2, and the recess 11 is disposed on the lower guide 1. The interplay of the protrusion and recess forms a stable and precise positioning, ensuring that the cylindrical red steel passage channel 3 maintains a fixed position and orientation, allowing the red steel to move stably along a preset trajectory during high-speed movement, and preventing trajectory deviation caused by guide swaying or misalignment. In other embodiments, the protrusion 221 may also be disposed on the lower guide 1, and the recess 11 may also be disposed on the upper guide assembly 2.
[0045] Preferably, in this embodiment, the guide structure for the reducing machine further includes a pair of fixing pins. The fixing pins are sequentially inserted into the lower guide 1 and the upper guide assembly 2. The fixing pins are inserted on both sides of the red steel passage channel 3. The fixing pins are set at the discharge end of the upper guide assembly 2. The rigid connection of the fixing pins further strengthens the positioning effect of the concave and convex fit of the discharge ends of the upper and lower guides 1, preventing relative displacement due to vibration or lateral impact when the red steel passes through at high speed. This ensures the long-term stability of the position, direction and shape accuracy of the cylindrical red steel passage channel 3. It can avoid problems such as guide swaying causing the red steel movement trajectory to deviate and ellipticity to exceed the standard. It can also buffer the impact force through the rigid support of the fixing pins, reducing the interference of guide deformation on the surface quality and cross-sectional dimension consistency of the red steel.
[0046] Preferably, such as Figures 1-7 As shown, in this embodiment, the feeding end of the upper guide assembly 2 and the feeding end of the lower guide 1 are covered to form the first feeding port 4. The first feeding port 4 is an outwardly expanding flared mouth, and the opening of the outwardly expanding flared mouth narrows from the outside to the middle. The first feeding port 4 is located at the starting position of the red steel passage channel 3. The outward expansion structure can guide the red steel to enter the passage channel more smoothly, reducing the resistance and deviation risk when the red steel is fed. The design of narrowing in the middle can perform preliminary calibration of its position in the early stage of the red steel entering the channel, so that the red steel is more accurately aligned with the passage channel, laying the foundation for stable operation in the channel. This structure not only improves the efficiency of red steel feeding, but also ensures the stability of the feeding process and reduces the subsequent processing quality problems caused by feeding deviation.
[0047] Preferably, such as Figure 4 and Figures 8-10 As shown, in this embodiment, a first stabilizing member 12 extends on both sides of the lower guide 1 radially. The first stabilizing member 12 extends along the movement direction of the red steel. A second stabilizing member 211 is provided at the corresponding position of the upper guide assembly 2 and the first stabilizing member 12. The first stabilizing member 12 is provided with a first limiting member 212 protruding in front of and behind the second stabilizing member 211. The first limiting member 212 is used to limit the displacement of the second stabilizing member 211 along the movement direction of the red steel. It can realize the precise limiting and stable connection of the upper and lower guides 1 in the movement direction of the red steel. The bidirectional limiting enhances the stability of the overall structure of the guide, avoids the upper guide assembly 2 from moving or displacing along the movement direction during the high-speed movement of the red steel, ensures that the position of the columnar red steel passage channel 3 is always fixed, thereby ensuring the stability of the red steel movement trajectory, reducing the red steel shape defects and quality problems caused by guide displacement, and providing a more reliable structural foundation for the subsequent processing of the red steel.
[0048] Specifically, such as Figures 4-7As shown, in this embodiment, the upper guide assembly 2 includes a front guide 21 and a rear guide 22. The rear guide 22 is located downstream of the front guide 21. The inlet end of the front guide 21 is aligned with the inlet end of the lower guide 1, and the outlet end of the rear guide 22 is aligned with the outlet end of the lower guide 1. The front guide 21 and the rear guide 22 are spaced apart, which enables timely and smooth discharge of iron oxide, avoiding the accumulation and residue of iron oxide in the red steel passage channel 3. This prevents the accumulated iron oxide from scratching the surface of the red steel and affecting its appearance quality. It also avoids the problem of increased friction between the red steel and the guide due to iron oxide entering the contact area between the red steel and the guide, which could lead to deviation of the red steel's movement trajectory and accelerated wear of the guide. Timely discharge of iron oxide can keep the cylindrical passage clean, maintain the accuracy of the channel shape, and ensure that the red steel passes through in a stable and clean environment. This effectively improves the processing quality of the red steel and the service life of the guide, reduces equipment maintenance costs, and ensures efficient and stable production operation.
[0049] Preferably, such as Figures 4-10 As shown, in this embodiment, the feed end of the rear guide 22 and the lower guide 1 are covered to form an auxiliary feed port 5. The auxiliary feed port 5 on the rear guide 22 is an outwardly expanding horn-shaped opening. The opening of the outwardly expanding horn-shaped opening narrows from the outside to the middle. The auxiliary feed port 5 is located in the middle of the red steel passage channel 3. The outwardly expanding horn-shaped opening has a guiding function, which plays a precise guiding role when the red steel enters the passage channel, making it easy for the red steel to be smoothly guided into the middle of the channel. At the same time, the middle narrowing structure provides initial constraint on the movement trajectory of the red steel, reducing the deviation and shaking when the red steel is fed in. Combined with the overall constraint of the passage channel, it further ensures the stability of the red steel's movement in the channel, reduces the problems of trajectory deviation and deformation caused by feed guidance deviation, and lays the foundation for the subsequent stable passage and quality assurance of the red steel.
[0050] Preferably, such as Figures 4-10As shown, in this embodiment, the second stabilizer 211 is disposed on the front guide 21. In the area corresponding to the rear guide 22 on the lower guide 1, a third stabilizer 13 extends radially to both sides of the lower guide 1. The third stabilizer 13 extends along the direction of movement of the red steel. A fourth stabilizer 222 is disposed on the upper guide corresponding to the third stabilizer 13. The third stabilizer 13 has a second limiting member 223 protruding before and after the fourth stabilizer 222. The second limiting member 223 is used to limit the displacement of the fourth stabilizer 222 along the direction of movement of the red steel. The third stabilizer 13 extending axially to both sides of the lower guide 1 and the third stabilizer 13 with its third stabilizing member 222 protruding on it... The second limiting member 223, located before and after the fourth stabilizing member 222, cooperates with the fourth stabilizing member 222 of the rear guide 22 to limit the displacement of the rear guide 22 along the direction of the red steel movement. The second limiting member 223 realizes the axial positioning of the rear guide 22 along the lower guide 1, enhances the stability of the guide structure in the direction of the red steel movement, avoids the upper guide assembly 2 from being displaced due to the high-speed passage of the red steel, ensures the fixed position of the columnar passage channel, and thus ensures the stability of the red steel movement trajectory, reduces quality defects such as excessive ellipticity and surface scratches caused by guide misalignment, and provides a blank with reliable dimensional accuracy for subsequent processing of the red steel.
[0051] Specifically, such as Figures 1-10 As shown, in this embodiment, the guide structure for the reducing machine also includes a base 6, with the lower guide 1 mounted on the base 6 to provide stable support for the lower guide 1. This provides a solid installation foundation for the entire guide structure for the reducing machine. By fixing the lower guide 1 to the base 6, it ensures that the lower guide 1 remains stable during the high-speed passage of the red steel, preventing the lower guide 1 from swaying due to insufficient support from the base 6. This creates a more reliable concave-convex fit with the upper guide assembly 2, ensuring the positional accuracy and directional stability of the cylindrical red steel passage channel 3. At the same time, the base 6 provides a rigid support platform for the guide structure, effectively dispersing the impact force generated during the passage of the red steel, reducing the deformation of the guide structure for the reducing machine, further strengthening the constraint on the movement trajectory of the red steel, reducing the risk of red steel shape defects caused by the instability of the guide structure, and providing a more stable blank foundation for subsequent processing of the red steel.
