Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of steel smelting, especially relates to a wire rod roughing and intermediate rolling sliding import guide device. BACKGROUND

[0002] Guide devices play a crucial role in the process of profile steel rolling. They are installed at the front and rear positions of the roll pass, aiming to assist the rolled piece to accurately and stably enter and exit the roll pass according to the predetermined direction and state. The core function of this device lies in its ability to accurately guide the rolled piece into the roll pass, ensuring stable plastic deformation of the rolled piece inside the pass, and thus obtaining the required precise geometric shape and size specifications. In addition, the guide device is also responsible for smoothly guiding the rolled piece out of the pass, effectively preventing the occurrence of roll entanglement, and can control or force the rolled piece to twist or bend according to needs, ensuring its movement in a specific direction.

[0003] The sliding import guide body plays an indispensable role in the roughing and intermediate rolling stage. However, the existing structure design of the wire rod roughing and intermediate rolling sliding import guide has obvious deficiencies in the connection and fixation of the upper and lower two parts. During production operation, these guide devices often suffer from irregular stress, high temperature environment, and thermal alternating impact, which can easily lead to loosening or even breaking of the connection part. The occurrence of such problems not only seriously shortens the service life of the guide device and increases maintenance costs, but also may cause production accidents, posing a potential threat to the safe and stable operation of the production line. SUMMARY

[0004] To solve the problems existing in the prior art, the utility model provides a wire rod roughing and intermediate rolling sliding import guide device, which can prevent connection loosening or even breaking caused by irregular stress, high temperature, and thermal alternating impact during production operation, greatly improving the service life of the guide and reducing production accidents.

[0005] The utility model is realized in this way, a wire rod roughing and intermediate rolling sliding import guide device, including the guide base and guide upper cover that are relatively spliced, the guide base and guide upper cover are surrounded into the rolling channel for wire rod penetration between, the splicing end face of guide upper cover is provided with the clamping groove, the splicing end face of guide base is provided with the clamping block, the clamping block and clamping groove are matched and set up;

[0006] The side wall of guide base and guide upper cover is provided with the connecting part oppositely, the connecting part of guide base and the connecting part of guide upper cover are connected through the fastener.

[0007] Furthermore, the force-bearing surface where the slot and the block abut against each other is an inclined surface, and the inclination direction of the inclined surface is opposite to the forward direction of the rolled piece. The design of the inclined surface enables the block to gradually slide along the inclined surface when inserted into the slot and finally be firmly fixed in the slot. This process not only has a guiding effect, making the connection between the guide base and the upper cover smoother and more accurate, but also ensures the stability of the two after connection; the inclination direction of the inclined surface is opposite to the forward direction of the rolled piece, which means that when the rolled piece passes through the rolling channel, the connection between the block and the slot will be tighter, thereby further enhancing the positioning function of the guide device; the inclination direction of the inclined surface enables the friction between the block and the slot to gradually disperse and decrease along the direction of the inclined surface when the rolled piece passes, which helps to improve the wear resistance and service life of the guide device.

[0008] Furthermore, two sets of connecting parts are provided, one on the inlet and one on the outlet of the rolling channel. Providing connecting parts on both the inlet and outlet sides more effectively secures the guide base and cover, thereby enhancing the structural stability of the entire guide device. The two sets of connecting parts ensure more uniform force distribution, preventing damage or deformation to the equipment caused by excessive force at a single point. During the rolling process, the impact force of the wire on the guide device is shared by both sets of connecting parts, thereby improving the durability and service life of the equipment.

[0009] Furthermore, the slots and blocks are positioned near the exit of the rolling channel. During the rolling process, the wire undergoes a series of deformations before being guided out of the rolling channel. Placing the slots and blocks here ensures a more stable structure for the guide device during wire removal, reducing the risk of the wire deviating from its intended path due to vibration or impact. During the rolling process, the impact force of the wire on the guide device is primarily concentrated on the exit side. Placing the slots and blocks here can more effectively disperse and withstand these impact forces, preventing damage or deformation to the equipment due to excessive force at a single point.

[0010] The utility model has the following advantages and technical effects: due to the adoption of the above technical scheme, the guide base and the guide cover form a rolling channel to ensure the smooth passage of the rolled pieces; there is a connecting part on each side of the guide base and the guide cover, which are reinforced with bolts to ensure that the rolling channel is unobstructed while ensuring the reliable connection and convenient disassembly and assembly; the blocks and grooves provided on the guide base and the guide cover fix the connection position to ensure that the upper and lower split parts of the sliding inlet guide of the wire rough and medium rolling are effectively connected, preventing the connection from loosening or even breaking due to factors such as irregular force, high temperature and thermal alternating impact during production operation, greatly improving the service life of the guide and reducing production accidents.

[0020] Further, the force receiving surface of the clamping groove 2-1 abutting against the clamping block 1-1 is a slope, and the inclination direction of the slope is opposite to the advancing direction of the rolled piece. The design of the slope enables the clamping block 1-1 to gradually slide along the slope and be finally fixed in the clamping groove 2-1 when inserted into the clamping groove 2-1. This process not only has a guiding effect, making the connection between the guide shoe base 1 and the upper cover more smooth and accurate, but also ensures the stability of the two after connection; the inclination direction of the slope is opposite to the advancing direction of the rolled piece, which means that the connection between the clamping block 1-1 and the clamping groove 2-1 will be more tight when the rolled piece passes through the rolling channel 4, thereby further enhancing the positioning function of the guide device; the inclination direction of the slope enables the friction between the clamping block 1-1 and the clamping groove 2-1 to gradually disperse and decrease along the direction of the slope when the rolled piece passes through, which helps to improve the wear resistance and service life of the guide device.

In the rolling process, the impact force of the wire on the guide device is borne by the two groups of connecting parts 3, thereby improving the durability and service life of the equipment.

[0022] Further, the clamping groove 2-1 and the clamping block 1-1 are arranged near the outlet side of the rolling channel 4. In the rolling process, the wire is guided out from the outlet side of the rolling channel 4 after a series of deformations. Arranging the clamping groove 2-1 and the clamping block 1-1 at this position can ensure that the structure of the guide device is more stable when the wire is guided out, reducing the risk of the wire deviating from the predetermined path due to vibration or impact; in the rolling process, the impact force of the wire on the guide device is mainly concentrated on the outlet side. Arranging the clamping groove 2-1 and the clamping block 1-1 at this position can more effectively disperse and bear these impact forces, avoiding damage or deformation of the equipment due to excessive stress at a single point.
