Description

Technical Field

[0001] This utility model relates to the technical field of hot rolling processing equipment, and more specifically, to a pressure regulating structure for hot rolling reinforcement equipment. Background Technology

[0002] Hot rolling is a common and important processing technique in the processing of metallic materials and composite materials. Through hot rolling, the microstructure of materials can be improved, and their strength, toughness, and other properties can be enhanced to meet the application requirements of various fields.

[0003] Hot rolling reinforcement operations are typically performed on specialized hot rolling reinforcement equipment. Many types of such equipment are available on the market. Some have a constant distance between the upper and lower hot pressure rollers, requiring the raw material to be of a constant size. Others use multiple sets of hot pressure rollers with varying spacing to handle different materials. However, both fixed-size and multi-set hot pressure rollers suffer from the drawback of not being able to adjust the pressure. The pressure cannot be adjusted by the squeezing force between the upper and lower rollers, limiting its application and causing inconvenience to users. Therefore, we propose a pressure adjustment structure for hot rolling reinforcement equipment. Utility Model Content

[0004] The purpose of this invention is to provide a pressure regulating structure for hot rolling reinforcement equipment to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The pressure regulating structure of the hot rolling reinforcement equipment includes a support panel, on which a lower frame is mounted. Multiple pressure sensors are fixedly installed between the bottom of the lower frame and the support panel. A support frame is fixedly mounted on the upper surface of the support panel. Two symmetrical hydraulic cylinders are fixedly mounted on the top plate of the support frame. An upper frame is detachably mounted at the ends of the telescopic shafts of the two hydraulic cylinders. The upper frame is located directly above the lower frame. Hot rolling rolls are rotatably connected between the left and right side plates of the lower frame and between the left and right side plates of the upper frame via rotating shafts. A drive motor is coaxially mounted at the end of the rotating shaft. A control host is fixedly mounted on the side plate of the support frame.

[0007] Preferably, a plurality of support legs are fixedly installed at the bottom of the support panel, and the length of the support legs is between 80cm and 120cm.

[0008] Preferably, the support panel is provided with two symmetrical rectangular positioning holes on the left and right, and two symmetrical rectangular insert rods are fixedly installed on the bottom surface of the lower frame. The rectangular insert rods are located in the rectangular positioning holes and are inserted into the rectangular positioning holes.

[0009] This setting can limit the horizontal position of the lower frame, ensuring a more robust and stable structure.

[0010] Preferably, both the rectangular insert and the rectangular positioning hole have rectangular cross-sections, and the dimensions of the rectangular insert are adapted to the dimensions of the rectangular positioning hole.

[0011] Preferably, the pressure sensor housing is fixedly mounted with a mounting base at both the bottom and top, and the upper and lower mounting bases are respectively fixedly mounted on the support panel and the lower frame.

[0013] Preferably, a rectangular plate is fixedly installed at the end of the telescopic shaft of the hydraulic cylinder, and the upper frame is detachably installed on the bottom surface of the rectangular plate by a plurality of fastening bolts.

[0014] Preferably, a vertically arranged rectangular guide rod is fixedly installed at the center of the top surface of the upper frame, and a rectangular guide sleeve is fixedly installed on the bottom surface of the top plate of the support frame. The rectangular guide rod is located inside the rectangular guide sleeve and is slidably connected to the rectangular guide sleeve.

[0015] This feature ensures that the upper frame moves more stably and smoothly when moving up and down.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, by setting up a hydraulic cylinder, an upper frame and a lower frame, uses the telescopic shaft of the hydraulic cylinder to drive the upper frame to move up and down, thereby flexibly adjusting the distance between the hot rolling rollers on the upper and lower frames, changing the squeezing force of the upper and lower hot rolling rollers on the raw material, realizing the pressure adjustment function, solving the problem of the non-adjustable pressure of traditional fixed-gap hot rolling rollers, and can adapt to the hot rolling reinforcement needs of raw materials of different sizes, greatly expanding the application range of the equipment.

[0018] 2. This utility model, by installing multiple pressure sensors between the support panel and the lower frame, can accurately monitor the pressure values ​​between the upper and lower hot rolling rolls in real time during the hot rolling process and transmit the data to the control host. The control host can promptly control the hydraulic cylinder to adjust the pressure according to preset pressure parameters, ensuring that the hot rolling pressure is stable within a suitable range, improving the quality of hot rolling reinforcement, and guaranteeing the consistency of material performance after processing.

[0019] 3.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4This utility model provides a technical solution: a pressure adjustment structure for a hot rolling reinforcement equipment, including a support panel 1, a lower frame 3 on the support panel 1, a plurality of pressure sensors 31 fixedly installed between the bottom of the lower frame 3 and the support panel 1, a support frame 12 fixedly installed on the upper surface of the support panel 1, and a control host 13 fixedly installed on the side plate of the support frame 12. The pressure sensors 31 can monitor the pressure data between the upper and lower hot rolling rolls in real time and transmit the data to the control host 13, so that the operator or control system can grasp the pressure situation in time for precise adjustment and ensure the quality of hot rolling processing.

[0031] In this embodiment, two symmetrical hydraulic cylinders 2 are fixedly installed on the top plate of the support frame 12. The upper frame 21 is detachably installed at the ends of the telescopic shafts of the two hydraulic cylinders 2. The upper frame 21 is located directly above the lower frame 3. Hot rolling rolls 4 are rotatably connected between the left and right plates of the lower frame 3 and between the left and right plates of the upper frame 21 through rotating shafts 40. A drive motor 41 is coaxially installed at the end of the rotating shaft 40. The telescopic shafts of the hydraulic cylinders 2 drive the upper frame 21 to move up and down, thereby flexibly adjusting the distance between the upper and lower hot rolling rolls and changing the hot rolling pressure. This can adapt to the hot rolling requirements of raw materials of different thicknesses and materials, greatly expanding the application range and processing flexibility of the equipment.

[0032] like Figure 1 As shown, multiple support legs 10 are fixedly installed at the bottom of the support panel 1. The length of the support legs 10 is between 80cm and 120cm, so as to achieve stable support operation for the support panel 1.

[0033] like Figure 2 As shown, the support panel 1 is provided with two symmetrical rectangular positioning holes 11 on the left and right. Two symmetrical rectangular insert rods 30 are fixedly installed on the bottom surface of the lower frame 3. The rectangular insert rods 30 are located in the rectangular positioning holes 11 and are inserted into the rectangular positioning holes 11. The cross-sections of the rectangular insert rods 30 and the rectangular positioning holes 11 are both rectangular. The size of the rectangular insert rods 30 is adapted to the size of the rectangular positioning holes 11, which limits the lower frame 3 in the horizontal direction, effectively preventing the lower frame 3 from horizontally displacing during the hot rolling process, ensuring the structural stability of the lower frame 3, making the hot rolling process more stable and reliable, and improving the safety of equipment operation.

[0034] like Figure 2 and Figure 3 As shown, the pressure sensor 31 has a fixed base 32 fixedly installed at the bottom and top of the housing. The upper and lower fixed bases 32 are respectively fixedly installed on the support panel 1 and the lower frame 3, which facilitates the fixed installation operation between the pressure sensor 31 and the lower frame 3, ensuring that the pressure sensor 31 is firmly installed and can continuously and stably monitor the pressure during equipment operation, avoiding the impact of loose installation on the accuracy of pressure monitoring.

[0035] like Figure 3 As shown, a rectangular plate 20 is fixedly installed at the end of the telescopic shaft of the hydraulic cylinder 2. The upper frame 21 is detachably installed on the bottom surface of the rectangular plate 20 by multiple fastening bolts, which facilitates the installation, disassembly and maintenance of the upper frame 21. When it is necessary to repair or replace the upper frame 21 or its internal components, the operation can be quick, reducing the difficulty of equipment maintenance and downtime.

[0036] like Figure 3 As shown, a vertically arranged rectangular guide rod 22 is fixedly installed at the center of the top surface of the upper frame 21, and a rectangular guide sleeve 23 is fixedly installed on the bottom surface of the top plate of the support frame 12. The rectangular guide rod 22 is located inside the rectangular guide sleeve 23 and is slidably connected to the rectangular guide sleeve 23, providing guidance for the up and down movement of the upper frame 21, ensuring that the upper frame 21 moves smoothly and steadily during the movement, reducing shaking and offset, making the pressure adjustment between the hot rolling rolls more precise and stable, and improving the hot rolling processing accuracy.

[0037] It is worth noting that the pressure sensor 31 is used to detect pressure in real time. The control host 13 is equipped with a PLC controller, an operation panel, and a data processing module. The operation panel is located on the front side of the control host 13, and the operator can input the set value of rolling pressure, material parameters, and other information through the operation panel. The data processing module is used to receive the data fed back by the pressure sensor 31 and analyze and process the data. The PLC controller compares and analyzes the set value input by the operator and the actual pressure and position data fed back by the data processing module with the preset parameters, and then controls the extension and retraction of the hydraulic cylinder 2 to realize the automatic adjustment of the rolling pressure.

[0038] Finally, it should be noted that the pressure sensor 31, control host 13, hydraulic cylinder 2, and drive motor 41 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0039] When using the pressure regulating structure of the hot rolling reinforcement equipment of this utility model, the parameters of the material to be processed and the rolling pressure setting value are input into the PLC controller in the control host 13 through the operation panel.

[0040] The PLC controller calculates the initial extension and retraction of the hydraulic cylinder 2 based on the input information, controls the hydraulic cylinder 2 to move the rectangular plate 20 and the upper frame 21, adjusts the upper and lower hot rolling rollers 4 to a suitable distance, starts the drive motor 41, drives the rotating shaft 40 to rotate the hot rolling rollers 4, and feeds the material between the upper and lower hot rolling rollers 4 for hot rolling.

[0041] During the hot rolling process, pressure sensor 31 monitors the pressure between the upper and lower hot rolling rolls in real time and transmits the data to the data processing module of the control host 13. After analysis and processing, the data processing module transmits it to the PLC controller. The PLC controller compares the actual pressure with the set value. If there is a deviation, the PLC controller calculates the extension and retraction amount that the hydraulic cylinder 2 needs to be adjusted, controls its action, and adjusts the spacing of the hot rolling rolls 4 to accurately adjust the pressure until the hot rolling of the material is completed.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
