Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rolling, in particular to a rolling equipment with adjustable roll gap. BACKGROUND

[0002] In the process of mechanical automatic machining, the roller shaft is often used to roll the rolled material to make the rolled material meet the target size requirement. The rolling device is composed of two opposite synchronous rotating extrusion rollers. The material is fed between the two rollers and is subjected to high pressure extrusion. Nowadays, the roller shaft of the extrusion roller is prone to unbalanced force during rolling, which can cause the roller shaft to tilt and cause the problem of partial rolling, resulting in different roll gap sizes. This will cause the force on the entire surface of the material to be uneven, and it cannot be applied to materials of different thicknesses, and the utilization rate is low. CONTENT OF THE INVENTION

[0006] By adopting the above technical scheme, the base and the upper frame are both provided with two groups of parallel structures, and the upper frame is vertically above the base, which can provide a stable support structure. The connecting frame is connected to the opposite ends of the base and the upper frame, and the hydraulic cylinder is connected to the opposite ends of the base and the upper frame. Such design can realize the relative movement of the base and the upper frame, thereby adjusting the opening and closing angle of the roll gap. The rolling device is arranged on the base and the upper frame respectively, and is used for rolling the material located in the gap between the upper and lower groups of rolling devices. These rolling devices clamp the material and roll through the adjustment of the hydraulic cylinder. The hydraulic cylinder can adjust the opening and closing angle of the end close to the hydraulic cylinder between the base and the upper frame, thereby clamping the material and adjusting the thickness of the roll gap between the rolling devices.

[0007] Optionally, a plurality of cylinder pulling connections are arranged between the bases, and a plurality of cylinder pulling connections are arranged between the upper frame bodies.

[0008] By adopting the above technical solution, the cylinder pulling connections between the bases can be connected by multiple cylinder pulling connections, which can adjust and fix the relative positions between the bases. This design helps to ensure the parallelism and levelness between the bases, thereby ensuring the stability and precision of the roller pressing device. The cylinder pulling connections between the upper frame bodies can also be connected by multiple cylinder pulling connections to ensure the stability of the relative positions and angles between the upper frame bodies. This helps to maintain the parallelism and perpendicularity between the upper frame bodies, thereby ensuring the uniform rolling and processing precision of the roller pressing device on the material.

[0009] Optionally, the bases and the upper frame bodies are further provided with bearing seats and bearings, the number of the bearing seats is four, the bearing seats are respectively arranged on the two groups of bases and the two groups of upper frame bodies and correspond to each other, and the bearings are arranged in the bearing seats.

[0010] By adopting the above technical solution, the number of the bearing seats is four, which are respectively arranged on the two groups of bases and the two groups of upper frame bodies and correspond to each other. This layout helps to evenly distribute the support force and provide stable support in the entire device structure. The bearings are arranged in the bearing seats, which are mainly used to support and rotate the shaft part of the device, such as the roller pressing device or other moving parts. The design of the bearings reduces the friction between the moving parts, improves the operation efficiency of the device, and prolongs the service life of the device. The corresponding arrangement of the bearing seats on the bases and the upper frame bodies ensures the correct installation and alignment of the bearings, thereby reducing the swing or instability of the bearings during use and improving the stability and reliability of the device.

[0011] Optionally, the roller pressing device comprises an upper movable roller and a lower fixed roller, the upper movable roller is arranged between the bearing seats on the upper frame body, the upper movable roller is sleeved and rotated with the bearings in the bearing seats, the lower fixed roller is arranged between the bearing seats on the base, and the lower fixed roller is sleeved and rotated with the bearings in the bearing seats.

[0012] By adopting the above technical solution, the upper movable roller is arranged between the bearing seats on the upper frame body, and the upper movable roller is sleeved and rotated with the bearings in the bearing seats. This design ensures that the upper movable roller can freely rotate under the support of the bearings to effectively roll the material. The lower fixed roller is arranged between the bearing seats on the base, and the lower fixed roller is sleeved and rotated with the bearings in the bearing seats. Such design ensures that the lower fixed roller can also freely rotate under the support of the bearings to provide stable support for the material, so that the material can be uniformly rolled between the upper movable roller and the lower fixed roller.

[0013] Optionally, the roller pressing device further includes two drive motors, which are respectively mounted on the bearing seats on the base and the upper frame. The output end of the drive motor is driven to drive the upper moving roller and the lower fixed roller. The drive motor drives the upper moving roller and the lower fixed roller to rotate around their own axes in opposite directions.

[0014] By adopting the above technical solution, two drive motors are respectively mounted on bearing seats on the base and upper frame. This layout ensures that the drive motors correspond to the positions of the upper moving roller and the lower fixed roller, while providing the ability to perform bidirectional rolling of the material. The output ends of the drive motors are connected to the upper moving roller and the lower fixed roller, so that when the motors start, they drive the upper moving roller and the lower fixed roller to rotate around their own axes. This design allows the upper moving roller and the lower fixed roller to rotate simultaneously, thereby achieving effective rolling operation of the material. The drive motors drive the upper moving roller and the lower fixed roller to rotate around their own axes in opposite directions. This counter-rotation design helps to generate appropriate rolling pressure and ensures that the material is uniformly processed during the rolling process.

[0015] Optionally, the base and the upper frame are further provided with a pivot pin, the hydraulic cylinder is connected to the base and the upper frame through the pivot pin, and the connecting frame is also connected to the base and the upper frame through the pivot pin.

[0016] By adopting the above technical solution, the axle pin is located on the base and upper frame, used to connect the hydraulic cylinder and the connecting frame. This design provides a stable connection point, ensuring a firm connection between the hydraulic cylinder and the connecting frame and the base and upper frame. The hydraulic cylinder is connected to the base and upper frame via the axle pin. This connection method allows the hydraulic cylinder to apply force stably during the rolling operation and to accurately adjust the opening angle between the base and upper frame, thereby adjusting the thickness of the roll gap. The connecting frame is also connected to the base and upper frame via the axle pin. This connection method ensures a firm connection between the connecting frame and the base and upper frame, enabling the equipment to maintain a stable structure during operation and accurately control the movement of the rolling device.

[0017] Optionally, the connecting frame is provided with several sets of reinforcing ribs.

[0018] By adopting the above technical solution, the reinforcing ribs can effectively increase the overall structural strength of the connecting frame, enabling it to withstand greater forces and loads. This is crucial for withstanding the pressure and reaction forces of materials during roller pressing operations, preventing deformation or damage to the connecting frame during operation.

[0019] Optionally, the base is provided with a support rib on the side away from the roller pressing device.

[0020] By adopting the above technical solution, the addition of support ribs can increase the overall structural stability of the base. Especially during the rolling operation, when the base is subjected to large pressure and vibration, the support ribs can effectively resist these forces and prevent the base from becoming unstable or tilting.

[0021] 1. Both the base and the upper frame have two sets of parallel structures. The upper frame is located vertically above the base, providing a stable support structure. A connecting frame connects one end of the base and the upper frame, while a hydraulic cylinder connects the other end. This design allows for relative movement between the base and the upper frame, thereby adjusting the opening and closing angle of the roller gap. Roller pressing devices are respectively installed on the base and the upper frame to press the material located in the gap between the upper and lower sets of roller pressing devices. These roller pressing devices clamp and press the material through adjustment by the hydraulic cylinder. The hydraulic cylinder can adjust the opening and closing angle between the base and the upper frame near the hydraulic cylinder end, thereby clamping the material and adjusting the thickness of the roller gap between the roller pressing devices.

[0022] 2. Two drive motors are respectively mounted on bearing seats on the base and upper frame. This layout ensures that the drive motors correspond to the positions of the upper moving roller and the lower stationary roller, while providing the ability to roll the material in both directions. The outputs of the drive motors are connected to the upper moving roller and the lower stationary roller, so that when the motors start, they drive the upper moving roller and the lower stationary roller to rotate about their own axes. This design allows the upper moving roller and the lower stationary roller to rotate simultaneously, thereby achieving effective rolling operation of the material. The drive motors drive the upper moving roller and the lower stationary roller to rotate about their own axes in opposite directions. This counter-rotation design helps to generate appropriate rolling pressure and ensures that the material is uniformly processed during the rolling process;

[0023] 3. A pivot pin is located on the base and upper frame, used to connect the hydraulic cylinder and the connecting frame. This design provides a stable connection point, ensuring a secure connection between the hydraulic cylinder and the connecting frame and the base and upper frame. The hydraulic cylinder is connected to the base and upper frame via the pivot pin. This connection allows the hydraulic cylinder to apply force stably during the rolling operation and to accurately adjust the opening angle between the base and upper frame, thereby adjusting the roll gap thickness. The connecting frame is also connected to the base and upper frame via a pivot pin. This connection ensures a secure connection between the connecting frame and the base and upper frame, allowing the equipment to maintain a stable structure during operation and enabling precise control of the rolling device's movement.

[0027] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0028] This application discloses a roller pressing device with adjustable roller gap.

[0029] Reference Figure 1 The adjustable roller pressing equipment includes a base 1, an upper frame 2, roller pressing devices 3, a connecting frame 4, and a hydraulic cylinder 5. The double-parallel structure of the base 1 and the upper frame 2, with the upper frame 2 positioned vertically above the base 1, provides a stable support structure. This design ensures the stability and reliability of the equipment during operation, as well as the accuracy and consistency of the roller pressing operation. The design of the connecting frame 4 and the hydraulic cylinder 5 allows for relative movement between the base 1 and the upper frame 2, and adjusts the opening and closing angle of the roller gap. This flexible adjustment capability enables the equipment to adapt to materials of different sizes and shapes, and to perform precise roller pressing operations according to processing requirements. The roller pressing devices 3 are respectively mounted on the base 1 and the upper frame 2, and clamp the material and perform roller pressing through adjustment by the hydraulic cylinder 5. This design ensures that the roller gap thickness between the roller pressing devices 3 can be adjusted, and enables uniform roller pressing of the material, improving processing efficiency and quality. The hydraulic cylinder 5 adjusts the opening and closing angle between the base 1 and the upper frame 2, thereby precisely clamping the material and adjusting the roller gap thickness between the roller pressing devices 3. This precise control capability ensures that the equipment can meet different processing requirements and achieve fine control over the material processing process.

[0030] Reference Figure 1Multiple pull cylinders 6 connect the bases 1, allowing for adjustment and fixation of their relative positions. This design ensures parallelism and levelness between the bases 1, enabling the roller pressing device 3 to operate stably. This is crucial for ensuring the uniformity and precision of the processed materials. Similarly, multiple pull cylinders 6 connect the upper frames 2 to ensure the stability of their relative positions and angles. This helps maintain parallelism and perpendicularity between the upper frames 2, ensuring uniform roller pressing and high processing precision of the materials by the roller pressing device 3. This design effectively avoids processing deviations caused by tilting or deformation of the upper frames 2. By connecting the bases 1 and upper frames 2 with pull cylinders 6, more support points and adjustment capabilities are provided, enhancing the stability and processing precision of the equipment. This design allows the roller pressing device 3 to maintain consistent roller pressing effects under different processing conditions, improving processing quality and production efficiency.

[0031] Reference Figure 1 The roller pressing device 3 includes an upper moving roller 301 and a lower fixed roller 302. The upper moving roller 301 is mounted between bearing seats 7 on the upper frame 2 and rotates with bearings 8. This design ensures that the upper moving roller 301 can rotate freely with the support of bearings 8, providing the necessary rotational function for the roller pressing operation. The upper moving roller 301 is usually responsible for providing the main power for roller pressing, so its free rotation capability is crucial. The lower fixed roller 302 is mounted between bearing seats 7 on the base 1 and rotates with bearings 8. This design ensures that the lower fixed roller 302 can also rotate freely with the support of bearings 8. The lower fixed roller 302 is usually responsible for providing stable support for the material, ensuring that the material is uniformly pressed during the roller pressing process. The design and installation of the upper moving roller 301 and the lower fixed roller 302 ensure functionality and efficiency in the roller pressing operation. The upper moving roller 301 provides the main power, applying pressure to the material through free rotation, while the lower fixed roller 302 provides stable support, ensuring that the material remains stable during the roller pressing process. The combination of these two elements enables uniform rolling of materials. Bearing 8, housed within bearing housing 7, provides excellent support and rotational capacity for the upper moving roller 301 and the lower stationary roller 302. This helps reduce friction, improve operating efficiency, and extend the service life of the rolling device 3.

[0032] Reference Figure 1The roller pressing device 3 also includes drive motors 303. Two drive motors 303 are respectively mounted on bearing seats 7 on the base 1 and the upper frame 2, so that the drive motors 303 correspond to the positions of the upper moving roller 301 and the lower fixed roller 302. This layout ensures that the driving force can be effectively transmitted to the roller pressing device 3, thereby achieving bidirectional roller pressing operation on the material. The output end of the drive motor 303 is connected to the upper moving roller 301 and the lower fixed roller 302. When the drive motor 303 starts, it drives the upper moving roller 301 and the lower fixed roller 302 to rotate around their own axes. This design allows the upper moving roller 301 and the lower fixed roller 302 to rotate simultaneously, thereby achieving bidirectional roller pressing operation on the material. This is crucial for handling materials of different shapes and sizes and for achieving more complex processing operations. The drive motors 303 drive the upper moving roller 301 and the lower fixed roller 302 to rotate around their own axes in opposite directions. This counter-rotation design helps to generate appropriate roller pressure and ensures that the material is uniformly processed during the roller pressing process. This counter-rotation also allows for adjustment of the gap between the roller pressing devices 3 to meet different processing requirements. Since the drive motors 303 are respectively mounted on the bearing seats 7 on the base 1 and the upper frame 2, their tight connection with the roller pressing devices 3 ensures the effective transmission of driving force and guarantees the stability and reliability of the roller pressing operation.

[0033] Reference Figure 1 The base 1 and upper frame 2 are equipped with pivot pins 9. Pivot pins 9, located on the base 1 and upper frame 2, provide a secure connection point for the hydraulic cylinder 5 and the connecting frame 4. This design ensures a firm connection between the hydraulic cylinder 5 and the connecting frame 4 and the base 1 and upper frame 2, preventing loosening or detachment during operation and guaranteeing the safety and stability of the equipment. The hydraulic cylinder 5 is connected to the base 1 and upper frame 2 via pivot pins 9, allowing it to apply force stably during the rolling operation. This ensures that the rolling device 3 can effectively roll the material, improving processing efficiency and product quality. Through the pivot pin connection, the hydraulic cylinder 5 can accurately adjust the opening angle between the base 1 and upper frame 2, thereby adjusting the thickness of the roll gap. This design allows the equipment to adapt to materials of different sizes and shapes and perform precise rolling operations according to processing requirements, improving processing flexibility and accuracy. The connecting frame 4 is also connected to the base 1 and upper frame 2 via pivot pins 9, ensuring a secure connection between the connecting frame 4 and the base 1 and upper frame 2. This connection method enables the equipment to maintain a stable structure during operation, preventing equipment instability or damage caused by loose or deformed connecting parts, thus improving the reliability and durability of the equipment.

[0034] Reference Figure 1The connecting frame 4 is equipped with several sets of reinforcing ribs 10. The addition of reinforcing ribs 10 effectively increases the overall structural strength of the connecting frame 4. The arrangement of the reinforcing ribs 10 effectively disperses and transmits external pressure and force, thereby reducing the pressure on the stress points of the connecting frame 4 and lowering the risk of structural deformation or damage. During the rolling operation, the connecting frame 4 needs to withstand the pressure and reaction force from the material. The presence of the reinforcing ribs 10 can distribute these forces more evenly, effectively reducing the deformation or twisting of the connecting frame 4 and improving the stability and safety of the equipment. The connecting frame 4 may be subjected to significant forces and vibrations during operation, especially under high load conditions. The design of the reinforcing ribs 10 enhances the durability and deformation resistance of the connecting frame 4, preventing deformation or damage during use and extending the service life of the equipment. The reinforcing ribs 10 not only increase the strength of the connecting frame 4 but also help maintain its stability. The reinforcing ribs 10 can effectively absorb and disperse external pressure and force, reducing the swaying and vibration of the connecting frame 4 during operation and ensuring the stable operation of the equipment.

[0035] Reference Figure 1 A support rib 11 is provided on the side of the base 1 away from the roller pressing device 3. The addition of the support rib 11 can effectively increase the overall structural stability of the base 1. The base 1 may be subjected to significant pressure and vibration during roller pressing operations. The support rib 11 can provide additional support and reinforcement for the base 1, preventing instability or tilting. When the base 1 is subjected to the pressure and vibration applied by the roller pressing device 3, the support rib 11 can effectively resist these external forces. By increasing the support area and structural rigidity of the base 1, the pressure concentration at the stress points of the base 1 is reduced, thereby reducing the risk of deformation or damage to the base 1. The stability of the base 1 is crucial for operational safety. By adding the support rib 11, the stability and reliability of the base 1 during roller pressing operations can be improved, reducing the probability of accidents and protecting the safety of operators and equipment. The design of the support rib 11 can reduce the pressure load on the base 1 during operation, reduce the fatigue of the base 1, and extend its service life. This helps to reduce the frequency of equipment maintenance and replacement, and lower equipment operating costs.

[0036] Reference Figure 2The base 1 and upper frame 2 are equipped with bearing seats 7 and bearings 8. Four bearing seats 7 are respectively installed on two sets of bases 1 and two sets of upper frames 2, corresponding to each other. The bearings 8 are located within the bearing seats 7 and are mainly used to support and rotate the axial part of the equipment. The design of the bearings 8 effectively reduces friction between moving parts, improving the operating efficiency of the equipment. This design also helps reduce energy consumption and mechanical wear, extending the service life of the equipment. The corresponding installation of the bearing seats 7 on the bases 1 and upper frames 2 ensures the correct installation and alignment of the bearings 8. This helps reduce the swaying or instability of the bearings 8 during use, improving the stability and reliability of the equipment. Correct installation and alignment of the bearings 8 can also reduce equipment vibration and noise, improving processing quality.

[0037] The implementation principle of the adjustable roll gap rolling device in this application embodiment is as follows:

[0038] The operator places the material to be processed into the gap between the roller pressing device 3 and the base 1 and the upper frame 2. According to the processing requirements, the operator adjusts the hydraulic cylinder 5 to control the opening angle between the base 1 and the upper frame 2, thereby adjusting the roller gap thickness between the roller pressing devices 3. The hydraulic cylinder 5 adjusts the roller gap thickness between the roller pressing devices 3 by controlling the opening angle between the base 1 and the upper frame 2. When the hydraulic cylinder 5 applies force, the distance between the base 1 and the upper frame 2 changes, thus affecting the roller gap width of the roller pressing device 3. By adjusting the pressure and opening angle of the hydraulic cylinder 5, precise adjustment of the roller gap thickness can be achieved to meet the processing requirements of different materials. The operator starts the drive motor 303, driving the upper moving roller 301 and the lower fixed roller 302 to begin rotating. The drive motor 303 operates in the opposite direction to ensure that the rolling directions of the upper moving roller 301 and the lower fixed roller 302 are opposite. The material is held between the upper moving roller 301 and the lower fixed roller 302. As the upper moving roller 301 and the lower fixed roller 302 rotate, the material is uniformly rolled. Due to the design and adjustment of the rolling device 3, the material can be uniformly processed during the rolling process to achieve the required thickness and shape. The operator can adjust the parameters of the hydraulic cylinder 5, such as the opening and closing angle and pressure, at any time according to the processing effect and actual needs to achieve more precise processing requirements. At the same time, the operator monitors the operation of the equipment to ensure that the processing is carried out smoothly. When processing is completed, the operator stops the drive motor 303 and removes the processed material from the equipment. Subsequent processing or handling can be carried out as needed.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
