TECHNICAL FIELD
[0001] The utility model relates to H shaped steel processing technical field especially relates to a guide and guard device for H shaped steel processing. BACKGROUND
[0002] H shaped steel processing is a process involving multiple key steps and complex technology, and the raw material of H shaped steel is usually wide blank produced by steel plant. The quality and size of these raw materials need to meet the design requirements and pass strict inspection. The preparation of raw materials is the first step of H shaped steel processing and also the basis to ensure the quality of final products. According to the specific size and shape requirements, the raw materials need to be accurately cut. This can be realized by manual cutting or mechanical cutting, including methods such as flame cutting, plasma cutting and laser cutting. After cutting, the raw materials also need to be pretreated, such as straightening and surface cleaning, to eliminate internal stress and remove surface impurities. The pretreated raw materials will enter the hot rolling processing stage. Hot rolling processing is to press the raw materials into the required shape of H shaped cross section through high temperature rolling. The parameters such as rolling force, rolling temperature and rolling speed need to be strictly controlled in this process to ensure the dimensional accuracy and internal quality of H shaped steel. The H shaped steel after hot rolling needs to be cold drawn to further improve its surface quality and dimensional accuracy. Cold drawing is to make the size of H shaped steel more accurate by rolling again and remove the surface defects caused by rolling. Then, the H shaped steel needs to be straightened, which restores its original shape through stretching or compression and achieves good straightness and bending degree. In order to prevent corrosion and oxidation of H shaped steel during use and improve its coating adhesion, surface treatment is needed. Common surface treatment methods include pickling, sand blasting and hot dip galvanizing. These treatments can enhance the durability and aesthetics of H shaped steel. The H shaped steel after surface treatment needs to be cut to size according to the design requirements to ensure the length and angle accuracy of the final product. After completing the processing, the H shaped steel also needs to be strictly inspected and quality controlled, including detection of size, weight, mechanical properties and surface quality. Only the H shaped steel that passes the inspection can enter the next process.
[0003] Guide is a device installed before and after the roll pass, used to help the rolled piece accurately and stably enter and exit the roll pass according to the established direction and state. It ensures that the rolled piece can enter the roll according to the predetermined path, avoids deviation during rolling, prevents the rolled piece from being damaged during rolling, such as straightening the side bending part of the head of the rolled piece, and avoids defects such as twisting and bending of the rolled piece. Through accurate design and manufacturing, the guide device can ensure the quality and precision of H-shaped steel rolling. Among them, the rolling guide: the rolling guide is more stable, and the distance between the guide rollers can be easily adjusted to adapt to rolled pieces of different specifications and shapes. In addition, the rolling guide also has the advantages of removing iron oxide scale, making the surface of the rolled piece smoother, and increasing the surface strength of the rolled piece. However, the cost of the rolling guide is relatively high. The sliding guide: the cost of the sliding guide is relatively low, but the stability is not as good as the rolling guide, and it is not easy to adjust. In actual application, the sliding guide is usually used in situations where the rolling precision requirement is not high. In the H-shaped steel processing process, the guide device is widely used in various rolling stages. Through accurate design and manufacturing, the guide device can ensure stable transmission of the rolled piece during rolling.
[0004] In the process of H-shaped steel processing, in order to ensure the stability of the H-shaped steel processing process, guide is needed, but we consider that the traditional rolling guide mechanism cannot be adjusted at any time, and the rolling guide mechanism needs to be disassembled as a whole and installed according to the different specifications of the required guide H-shaped steel, which greatly reduces the efficiency of the H-shaped steel guide and the overall processing efficiency, which is extremely inconvenient, so an H-shaped steel processing guide device is needed to solve the above problems.

[0024] Further, the top side of the bearing plate 2 is fixedly connected with the bottom frame 7, and the inner side of the bottom frame 7 is rotatably connected with the bearing wheel 8 through the shaft, which can support the bottom of the H-shaped steel.
[0025] Further, the two sides of all gyro wheels 6 are rotatably connected with the inner walls of all guide plates 5 through shafts respectively.
[0026] Further, the outer sides of all outer tubes 11 are sleeved with stretch springs 12, and two of all top plates 9 located in the same horizontal direction are elastically connected through the stretch springs 12, which can make the two top plates 9 have a certain elastic extrusion degree.
[0027] Further, the output shafts of the two hydraulic oil cylinders 3 are slidably connected with the frame body 1.
[0028] Further, the bottoms of the two push plates 4 are fixedly connected with sliding blocks 13, and the two sliding blocks 13 are slidably connected with the bottoms of the frame bodies 1 through sliding grooves 14, which can improve the stability of the push plates 4 in movement by sliding in the sliding grooves 14.
[0029] In summary:
[0030] At the beginning of using the device, the operator needs to carefully place the H-shaped steel to be processed on the top of the bearing plate 2, which ensures that the H-shaped steel can be accurately positioned between the rollers 6 equipped on the two special push plates 4, which are designed to closely match the profile of the H-shaped steel, laying a solid foundation for subsequent stable processing. In order to achieve the initial stability of the H-shaped steel, the elastic extrusion mechanism between the top plates 9 arranged on the top of the bearing plate 2 is used to generate a stable clamping force through moderate elastic deformation, effectively preventing any slight movement or shaking of the H-shaped steel before processing, thereby greatly improving the accuracy and safety of the processing. Subsequently, the operator will simultaneously start the two hydraulic cylinders 3, which serve as the power source. Through the hydraulic cylinders 3, the two push plates 4 are driven to move closer to each other in a smooth and coordinated manner. As the push plates 4 move, the rollers 6 installed on them gradually apply uniform and forceful extrusion to the H-shaped steel. This step not only further consolidates the stability of the H-shaped steel, but also achieves fine adjustment of its shape and position through the close contact between the rollers 6 and the surface of the H-shaped steel, creating ideal conditions for subsequent processing procedures. In addition, the device also integrates the bearing wheels 8 design in the bottom frame 7 part. These bearing wheels 8 not only have high bearing capacity, but also can rotate flexibly, effectively supporting the bottom of the H-shaped steel. This design not only reduces the weight pressure of the H-shaped steel during transportation, but also significantly enhances the stability and guidance of the H-shaped steel during transportation through multi-point support, avoiding processing errors caused by vibration or deviation, thereby ensuring the quality and processing efficiency of the final product. The H-shaped steel is limited by the rolling guide mechanism, so it will be more stable during movement. The H-shaped steel processing guide device of the utility model, through a series of carefully designed mechanical structures and innovative technologies, not only realizes the stable fixation of the H-shaped steel before processing, but also provides reliable guide function during transportation, greatly improving the stability and precision of H-shaped steel processing.
