DETAILED DESCRIPTION

[0018] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific embodiments. Figure 1 The orientation is used as a reference.

[0019] The modular sizing machine proposed in the embodiment of the present invention, when it is necessary to produce products of different lengths, only needs to assemble the C-type rack module group according to the length of the specific product. By selecting the number of C-type rack modules 100 in a targeted manner, products with different specifications and process requirements can be produced in a targeted manner.

[0020] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0021] like Figures 1 to 6 As shown, according to an embodiment of the present application, a modular sizing machine is proposed, comprising: at least two C-type frame modules 100, which are detachably installed together in parallel along a first direction to form a C-type frame module group, and a mounting groove 101 is formed on the same side of the C-type frame modules 100 arranged in parallel; a power transmission member 200, which is arranged on the C-type frame module 100; and a roller frame module 300. When the roller frame module 300 is installed in the mounting groove 101, the power transmission member 200 is connected to the roller frame module 300.

[0022] The modular sizing machine provided in the embodiment of the present application includes a C-type frame module 100, a power transmission member 200 and a roll frame module 300, wherein at least two C-type frame modules 100 are detachably installed in parallel along a first direction and then together to form a stable C-type frame module group, wherein the detachable installation method can be selected but not limited to bolt connection, and the C-type frame modules 100 arranged in parallel and adjacent to each other are tightly connected together by bolts, and at the same time, the same side of the C-type frame modules 100 arranged in parallel is formed with an installation groove 101, which provides an installation position for the roll frame module 300; the power transmission member 200 is arranged on the C-type frame module 100, and when the roll frame module 300 is installed in the installation groove 101, the power transmission member 200 is connected to the roll frame module 300 to transmit power to it; Exemplarily, at least two C-type frame modules 100 are arranged in parallel along the first direction to ensure that the spacing between the modules is appropriate and stable. During the installation process, they can be fixed together with bolts to ensure the integrity and stability of the C-type frame module group. When it is necessary to produce products with large differences in specifications and diameter reduction rates, it is only necessary to assemble the C-type frame module group in a targeted manner according to the process requirements of the corresponding products, and the axes of the working holes of adjacent rolling mill frame modules 300 coincide.

[0023] Exemplarily, the power transmission member 200 is installed on the C-type frame module 100, ensuring that the installation position is accurate so that it can be smoothly connected with the subsequently installed roller frame module 300; then the roller frame module 300 is installed in the installation groove 101 on one side of the C-type frame module 100. During the installation process, the matching accuracy between the roller frame module 300 and the installation groove 101 is ensured to ensure the stability and coaxiality after installation; exemplarily, positioning pins or other positioning devices can be used to assist the installation to ensure that the installation position of the roller frame module 300 is accurate.

[0024] During operation, the number of C-type frame modules 100 is first selected according to the process requirements of the product to be produced, and multiple C-type frame modules 100 are arranged side by side along a first direction by bolt connection. When the multiple C-type frame modules 100 are assembled into a C-type frame module group, the power transmission member 200 transmits power to the roller frame module 300 through a specific transmission method (such as gear transmission, shaft transmission, etc.), so that the rollers in the roller frame module 300 start to rotate, and the workpiece passing through the sizing machine is processed. In this process, since the roller frame module 300 is coaxially arranged and tightly connected to the power transmission member 200, the high efficiency and stability of power transmission can be guaranteed.

[0025] Exemplarily, the stability and connection strength of the C-type frame module 100 are regularly checked to ensure that it can withstand the pressure and impact force during operation. Professional testing equipment can be used to test the C-type frame module 100, and problems can be repaired or replaced in a timely manner. The power transmission component 200 is regularly maintained and serviced, including cleaning, lubrication, adjustment and other operations. Check the wear of the transmission components, and replace severely worn components in a timely manner to ensure the transmission efficiency and stability of the power transmission component 200. Regularly check the working status of the roller frame module 300, including the wear of the rollers, the lubrication of the bearings, etc. Replace severely worn rollers and lubricate the bearings regularly to ensure the working performance and life of the roller frame module 300.

[0026] Exemplarily, the power transmission member 200 may be selected from but not limited to a transmission shaft, and the roll frame module 300 installed in the installation groove 101 may be driven and operated by an external device through the power transmission member 200 .

[0027] like Figures 1 to 6As shown, in some examples, the modular sizing machine also includes: a mobile carrying mechanism 400, which is slidably installed on one side of the above-mentioned C-type frame module group, and is used to carry the above-mentioned roll frame module 300; a roll changing assembly 500, which is arranged on the above-mentioned mobile carrying mechanism 400 and is detachably connected to the above-mentioned roll frame module 300, and is used to move the above-mentioned roll frame module 300 between the above-mentioned mounting groove 101 and the above-mentioned mobile carrying mechanism 400; a power assembly 600, which is connected to the above-mentioned power transmission member 200, and is used to drive the above-mentioned roll frame module 300 to operate through the above-mentioned power transmission member 200.

[0028] In this technical solution, a mobile carrying mechanism 400 is slidably installed on one side of the C-type frame module group, and can carry the roll frame module 300. A roll changing assembly 500 is arranged on the mobile carrying mechanism 400. When the roll frame module 300 needs to be replaced, the roll changing assembly 500 plays a role, so that the roll frame module 300 moves between the installation groove 101 and the mobile carrying mechanism 400, and a fast roll changing operation is realized, so that the modular sizing mill has higher flexibility and maintainability, and can adapt to different production needs.

[0029] Exemplarily, the mobile bearing mechanism 400 is slidably installed on one side of the C-type frame module group; when installing the mobile bearing mechanism 400, ensure that its sliding track is flat and smooth so that it can smoothly carry the roll frame module 300 to move. At the same time, check the sealing and lubrication of the sliding mechanism to ensure that it will not get stuck or excessively worn during long-term use; finally, install the roll changing assembly 500 on the mobile bearing mechanism 400 and ensure that it can be detachably connected to the roll frame module 300. When installing the roll changing assembly 500, ensure the reliability and ease of operation of its connection mechanism so that it can be quickly and accurately connected and disassembled when the roll frame module 300 needs to be replaced.

[0030] When the roll frame module 300 needs to be replaced, the mobile bearing mechanism 400 is first controlled to move to one side of the C-type frame module 100 where the roll frame module 300 needs to be replaced. The movement of the mobile bearing mechanism 400 can be achieved by motor drive, hydraulic drive or other drive methods to ensure that the moving speed and position accuracy can meet the requirements of the roll changing operation. When the mobile bearing mechanism 400 reaches the specified position, the roll changing assembly 500 is connected to the roll frame module 300. The connection method can be mechanical connection, electromagnetic connection or other reliable connection methods to ensure that the connection is firm and can withstand the weight of the roll frame module 300 and the impact force during operation. After the connection is completed, the roll frame module 300 is driven by the roll changing assembly 500 to move from the installation groove 101 to the mobile bearing mechanism 400. In this process, the roll changing assembly 500 needs to have sufficient strength and accuracy to ensure that the roll frame module 300 can move smoothly and safely. Hydraulic jacks, electric hoists or other lifting equipment can be used to assist the roll changing assembly 500 in moving operations.

[0031] After the roll frame module 300 is moved onto the mobile bearing mechanism 400, the mobile bearing mechanism 400 carries the roll frame module 300 and moves it in a direction away from the C-type frame module group, so as to replace the roll frame module 300. During the movement, attention should be paid to maintaining the stability and safety of the mobile bearing mechanism 400 to avoid accidents.

[0032] When installing a new roll frame module 300 into the installation groove 101, first place the roll frame module 300 to be replaced on the mobile bearing mechanism 400. When placing, ensure that the position of the roll frame module 300 is accurate so that the subsequent installation operation can proceed smoothly. Then, apply an external force to the mobile bearing mechanism 400 to move the mobile bearing mechanism 400 on one side of the C-type frame module group to the installation groove 101 to be installed. During the movement, pay close attention to the position and state of the mobile bearing mechanism 400 to ensure that it can accurately reach the specified position; when the mobile bearing mechanism 400 reaches the side of the installation groove 101, the roll changing assembly 500 is connected to the roll frame module 300, and the connection method is the same as when replacing the roll frame module 300, ensuring that the connection is firm and reliable. Then, the roll changing assembly 500 moves to drive the roll frame module 300 from the mobile bearing mechanism 400 to the installation groove 101. During the movement, it is necessary to control the movement speed and force to ensure that the roll frame module 300 can be smoothly and accurately installed in the installation groove 101. Finally, after the roll frame module 300 is installed in the installation groove 101, the roll changing assembly 500 is separated from the roll frame module 300 to complete the installation operation of the roll frame module 300. The separation method can adopt the corresponding operation method according to the different connection methods to ensure that the separation process is safe and reliable.

[0033] It can be seen from the above content that by using the roller changing assembly 500 and the mobile bearing mechanism 400 in coordination with each other, the operation of quickly replacing the roller frame module 300 can be realized, which greatly shortens the roller changing time and improves production efficiency. At the same time, the modular design enables the sizing machine to be flexibly configured according to different production needs and adapt to the processing of workpieces of different specifications and types. Each module is relatively independent, which is convenient for maintenance and maintenance. When a module fails, it can be repaired or replaced separately without affecting the normal operation of the entire sizing machine. The fast roller changing operation and flexible configuration method can reduce equipment downtime, improve production efficiency and reduce production costs.

[0034] By using the roll changing assembly 500 and the mobile bearing mechanism 400 in cooperation with each other, the roll frame module 300 can be moved between the mounting groove 101 and the mobile bearing mechanism 400 to achieve a quick roll changing operation, so that the modular sizing mill has higher flexibility and maintainability and can adapt to different production needs.

[0035] In some examples, the power assembly 600 includes: a driving motor 610; a coupling 620, one end of which is connected to the output end of the driving motor 610 and the other end of which is connected to the power transmission member 200. The power assembly 600 also includes: a reducer 630, which is disposed between the driving motor 610 and the coupling 620.

[0036] In this technical solution, the modular sizing machine also includes a power assembly 600 connected to the power transmission member 200, through which the power assembly 600 can drive the power transmission member 200 to operate, and drive the roll frame module 300 to operate. The power assembly 600 includes a drive motor 610, a coupling 620 and a reducer 630, and the drive motor 610, the coupling 620 and the reducer 630 are arranged in sequence along an axis to ensure efficient transmission of power. As a power source, the drive motor 610 should be selected with a model with suitable power and speed to meet the operation requirements of the roll frame module 300. The coupling 620 plays the role of connecting the drive motor 610 and the power transmission member 200, and the selection of its type should be determined according to the specific parameters of the motor and the transmission member. For example, for applications with high speed and high torque, an elastic coupling can be selected to absorb shock and vibration. The reducer 630 is arranged between the drive motor 610 and the coupling 620, and its main function is to reduce the output speed of the motor and increase the output torque at the same time. For example, the type of reducer 630 can be selected according to actual needs, such as a planetary reducer, a gear reducer, etc.

[0037] When installing the drive motor 610, first ensure that the installation foundation is firm and reliable. You can use anchor bolts to fix the drive motor 610 to the base of the equipment to prevent the drive motor 610 from displacement or vibration during operation. When connecting the power line and control line of the drive motor 610, you should strictly follow the wiring diagram of the drive motor 610 to ensure that the wiring is correct.

[0038] The installation of the reducer 630 should be carried out according to its type and specifications. The reducer 630 should be installed in a horizontal position, and the connection with the drive motor 610 and the coupling 620 should be firm and reliable.

[0039] Exemplarily, the operation of the power assembly 600 can be performed through a control panel, a remote control or an automated control system. Before starting the power assembly 600, check whether the connections of the various components are firm, whether the lubricating oil is sufficient, and whether the control system is normal. Only after confirmation can the motor be started. During operation, the speed and torque of the drive motor 610 should be adjusted according to production requirements. Adjustments can be made through the speed knob on the control panel or the automated control system to achieve precise control of the roll frame module 300. When it is necessary to stop the power assembly 600, the speed of the drive motor 610 should be gradually reduced, and then the power supply of the drive motor 610 should be turned off. Avoid damage to the equipment caused by sudden shutdown.

[0040] The driving motor 610 provides power, and through the cooperation of the coupling 620 and the reducer 630, the power can be efficiently transmitted to the power transmission member 200, thereby driving the roller frame module 300 to operate. The function of the reducer 630 is to reduce the output speed of the driving motor 610 and increase the output torque. This enables the power assembly 600 to adapt to a larger load and improve the working efficiency of the equipment. By adjusting the speed of the driving motor 610 and the transmission ratio of the reducer 630, the speed of the roller frame module 300 can be adjusted to meet the needs of different production processes.

[0041] In summary, the power assembly 600 is an important part of the modular sizing mill, which can provide powerful power for the roll stand module 300 to achieve efficient, flexible and reliable operation. Through reasonable installation, operation and maintenance, the advantages of the power assembly 600 can be fully utilized to improve the production efficiency and product quality of the modular sizing mill.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in some examples, a height difference is formed between the power transmission components 200 on adjacent C-type rack modules 100 .

[0043] In this technical solution, a height difference is formed between the power transmission components 200 of adjacent C-type rack modules 100, such as Figure 5 and Figure 6 As shown, Figure 5 A schematic diagram of the structure of a C-type rack module 100 in one state of a power transmission member 200; Figure 6 It is a structural schematic diagram of a C-type frame module 100 in another state of the power transmission member 200. The power transmission members 200 of adjacent C-type frame modules 100 are arranged at different heights, so that the power components 600 connected thereto can also be arranged at a high height, so that the adjacent power components 600 can be installed compactly, thereby achieving the effect of saving space; at the same time, the roll frame module 300 is a symmetrical structure and can be installed in the installation groove 101 in both directions without affecting the normal operation of the roll frame module 300.

[0044] As can be seen from the above content, the above structure can effectively utilize space, especially in a production environment with limited space, and can better adapt to site requirements. On the other hand, the symmetrical structure of the roller frame module 300 increases the flexibility of installation, improves production efficiency and the maintainability of the equipment. During the installation and commissioning process, the staff can choose a suitable installation method according to the actual situation, making the installation of the equipment more convenient. During maintenance, the symmetrical structure also makes it easier to replace parts and reduces maintenance costs. In addition, the high and low design of the power transmission parts 200 can also optimize the power transmission efficiency of the equipment, reduce energy loss, and improve the overall performance of the equipment.

[0045] like Figure 1 , Figure 2 and Figure 4 As shown, in some examples, the roll changing assembly 500 includes: a roll changing trolley 510, which is slidably mounted on the movable supporting mechanism 400 along the second direction; a hook 520, which is arranged on the side of the roll changing trolley 510 close to the C-type frame module 100 and is used to connect with the rolling mill frame module 300; and a roll changing driving member 530, which is arranged on the roll changing trolley 510 and is used to drive the roll changing trolley 510 to move toward or away from the C-type frame module 100.

[0046] In this technical solution, the roll-changing trolley 510 is slidably installed on the mobile bearing mechanism 400 along the second direction. This installation method enables the roll-changing trolley 510 to move stably in a specific direction, providing a basis for subsequent roll-changing operations. The hook 520 is arranged on the side of the roll-changing trolley 510 close to the C-type frame module 100, and is used to connect with the roll frame module 300. During the roll-changing process, the hook 520 can accurately connect with the roll frame module 300 to ensure the smooth progress of the roll-changing operation. The roll-changing driving member 530 is arranged on the roll-changing trolley 510, and is used to drive the roll-changing trolley 510 to move in a direction close to or away from the C-type frame module 100; this structure can realize a more automated and efficient roll-changing operation, and reduce the difficulty and risk of manual operation. In actual production, the various parts of the roll-changing assembly 500 cooperate with each other, and can quickly and accurately complete the roll replacement work, thereby improving production efficiency and equipment reliability. At the same time, this structure also provides convenience for the maintenance and maintenance of the equipment, and reduces maintenance costs.

[0047] Exemplarily, the first direction and the second direction are perpendicular to each other.

[0048] like Figure 1 , Figure 2 and Figure 4As shown, in some examples, the mobile supporting mechanism 400 includes: a track 410, which is arranged on one side of the above-mentioned C-type rack module group; a mobile base 420, which is movably installed on the above-mentioned track 410, and the above-mentioned roller changing assembly 500 is arranged on the above-mentioned mobile base 420.

[0049] In this technical solution, the track 410 is arranged on one side of the C-type rack module group, providing a stable moving path for the mobile base 420. The mobile base 420 is movably installed on the track 410 and can move smoothly along the track 410, and the roller changing assembly 500 is arranged on the mobile base 420. This structure enables the roller changing assembly 500 to move on the track 410 along with the mobile base 420, so that the roller changing operation can be performed more conveniently. In actual production, this design can improve the efficiency and accuracy of roller changing, reduce the difficulty and risk of manual operation, and at the same time, the various parts of the mobile bearing mechanism 400 cooperate with each other, which can provide guarantee for the stable operation of the equipment and improve the reliability and service life of the equipment.

[0050] Exemplarily, the track 410 is arranged parallel to the first direction.

[0051] like Figures 1 to 6 As shown, in some examples, the modular sizing machine further includes: a locking member 700, which is disposed on the above-mentioned C-type frame module 100, and when the above-mentioned roller frame module 300 is installed in the above-mentioned mounting groove 101, the above-mentioned locking member 700 is tightly fitted with the above-mentioned roller frame module 300.

[0052] In some examples, an inclined surface 701 that contacts the locking member 700 is formed on the C-shaped rack module 100 .

[0053] In this technical solution, the modular sizing machine also includes a locking member 700, which is arranged on the C-type frame module 100. When the roll frame module 300 is installed in the installation groove 101, the locking member 700 is tightly fitted with the roll frame module 300 to ensure the stability of the roll frame module 300 during operation. An inclined surface 701 in contact with the locking member 700 is formed on the C-type frame module 100. This structure can increase the contact area between the locking member 700 and the C-type frame module 100, thereby improving the locking effect. In actual production, the locking member 700 can effectively prevent the roll frame module 300 from loosening or displacement during operation, thereby ensuring the normal operation of the equipment and the stability of production. At the same time, the design of the inclined surface 701 also makes the installation and disassembly of the locking member 700 more convenient, thereby improving the maintenance efficiency of the equipment.

[0054] Exemplarily, the angle between the inclined surface 701 and the horizontal direction may be 15-45°.

[0055] Exemplarily, the locking member 700 may be, but is not limited to, a hydraulic telescopic rod.

[0056] like Figure 1 As shown, in some examples, the bearing surface of the above-mentioned roll changing trolley 510 and the bearing surface of the above-mentioned mounting groove 101 are in the same plane, which can facilitate the replacement of the roll frame module 300 between the roll changing assembly 500 and the mobile supporting mechanism 400, realize smooth movement between the mounting groove 101 and the mobile supporting mechanism 400, and realize fast roll changing operation.
