Description

Technical Field

[0001] This utility model relates to the field of plate rolling machine processing technology, and in particular to a plate rolling machine with a protective device. Background Technology

[0002] Plate rolling machines, as common sheet metal forming equipment, are widely used in shipbuilding, pressure vessels, steel structure engineering, and other fields. They are mainly used to roll metal sheets into arc-shaped or cylindrical workpieces. After the rolling process is completed, the formed sheet needs to be removed from between the rolling rollers. This process usually requires lifting the upper roller and allowing the sheet to slide out along the roller axis. However, during this unloading process, there is a large area of ​​relative sliding between the sheet and the rolling roller surfaces. Since the rolling rollers and sheet are generally made of metal and their surfaces may have micro-protrusions, rust, or residual debris, they are very prone to scratches, indentations, and other damage to each other's surfaces.

[0003] Scratching is a particularly prominent issue during the unloading of large sheet metal. Due to their large mass, the normal pressure between the sheet metal and the roll increases, intensifying sliding friction. This not only makes the sheet surface more prone to scratches but also significantly increases the pushing or traction force required for unloading, reducing both ease of operation and safety. Furthermore, if the sheet metal surface is covered with scale, dust, or other hard impurities, these impurities can cause wear or indentations on the roll surface under high-pressure sliding friction, damaging the roll's precision profile and ultimately affecting the forming accuracy and workpiece quality in subsequent rolling processes.

[0004] Surface scratches are particularly detrimental to high-precision or high-surface-quality sheet materials such as stainless steel, coated plates, and mirror panels. Even minor scratches can lead to product downgrading or even scrapping, significantly increasing production costs. Currently, some companies are trying to alleviate this problem by manually padding with soft materials or applying lubricants, but these methods are cumbersome, inefficient, and can contaminate the sheet surface or the working environment. The protective effect is also inconsistent, making it especially difficult to meet the protection needs of large sheets and working conditions with impurities. Utility Model Content

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0029] This example provides a plate rolling machine with protective devices, which include protective devices installed on both sides of the main body 1 of the plate rolling machine. These devices are mainly used to solve the problem of surface scratches and roller wear caused by sliding friction between large or high-surface-requirement plates A and the rolling rollers 11 during unloading. The device uses a lifting and sliding mechanism to precisely deliver a set of conical protective rollers 4 to the bottom of the plate A, changing sliding friction into rolling friction, thereby achieving efficient and damage-free unloading.

[0030] refer to Figure 1-7The protective device includes a lifting frame 2 and a sliding assembly 3 mounted on the lifting frame 2. The upper surface of the lifting frame 2 is inclined towards the main body 1 of the plate rolling machine, forming an inclined plane with an inclination angle between 15° and 85°. The lifting frame 2 can be customized. Multiple protective rollers 4 are arranged on the sliding assembly 3 along the material feeding direction. The multiple protective rollers 4 are evenly spaced and are made of rubber, which has good elasticity. The protective roller 4 is specifically a conical roller, with a conical tip at one end near the main body 1 of the plate rolling machine and a roller shaft 41 coaxially mounted at the other end. The roller shaft 41 and the protective roller 4 are rotatably connected by bearings, and the roller shaft 41 is a steel shaft. After the sheet material is rolled into shape, it needs to be unloaded. At this time, the lifting frame 2 drives the sliding component 3 and the protective roller 4 to rise. The sliding component 3 drives the protective roller 4 to slide down along the upper inclined surface of the lifting frame 2 and approach the sheet material A. The upper winding roller 11 is raised, and the lower winding roller 11 is lowered at the same time. The sheet material A then falls onto the protective roller 4, so that the side wall of the protective roller 4 is tangent to the bottom of the formed sheet material A, so as to support the sheet material A and replace the winding roller 11 to roll relative to the sheet material A.

[0031] Specifically, the lifting frame 2, serving as the basic support and main drive unit of the entire protective device, adopts a combined structure of a fixed frame 21 and a movable frame 22, as shown in the reference. Figure 5 To ensure a stable and reliable lifting process, the lifting frame 2 includes a guide mechanism 241 consisting of two hydraulic slide rods and a guide mechanism 242 consisting of a guide rail slider assembly. This allows the movable frame 22 to move precisely vertically, driving the sliding assembly 3 and the protective roller 4 on it to lift as a whole. The upper end face of the lifting frame 2 is designed to be inclined towards the main body 1 of the plate rolling machine. The inclination angle can be customized. Generally, the angle between the upper end face and the horizontal plane is between 15° and 85°. This inclination angle ensures that the movement trajectory of the protective roller 4 on it can naturally match the curvature of the rolled cylindrical plate A, thereby accurately controlling the lifting height of the protective roller assembly and ensuring that it forms a stable tangential contact with the bottom of the plate, providing a basis for subsequent rolling friction. Simultaneously, it references... Figure 7 When not in operation, the lifting frame 2 can be lowered to a height below the lower winding roller 11, without affecting the normal feeding and winding process.

[0032] refer to Figure 2 The sliding assembly 3, installed on the inclined surface of the lifting frame 2, is used to adjust the working position of the protective roller 4. It mainly consists of a frame 31, a linear drive element 32, and a guide rail 33. The frame 31 slides with the guide rail 33 through a slider at the bottom and is driven by the linear drive element 32 to move along the inclined surface. To further enhance the stability of the movement, a side guide sleeve 342 is set at one end of the frame 31 to cooperate with the upper guide post 341 of the lifting frame 2. Through electric or pneumatic control, the entire protective roller assembly can be flexibly and accurately driven to slide along the inclined surface, thereby adaptively adjusting to adapt to different roll diameters and widths of plates, ensuring that all protective rollers 4 can achieve optimal line contact with the plate A.

[0033] refer to Figure 3 and Figure 4 Multiple protective rollers 4 are mounted on the spindle 312 of the frame 31 via their roller shafts 41. The spindle 312 is rotatably and horizontally mounted inside the steel outer frame 311. Multiple mounting holes 313 are machined axially along its side for mounting the roller shafts 41 of the protective rollers 4. The ends of the roller shafts 41 are machined with external threads and equipped with adjusting nuts 42. This structure not only realizes the quick installation and fixing of the protective rollers 4, but also allows for easy fine adjustment of the axial position and preload of each protective roller 4 by tightening the adjusting nuts 42, ensuring that each roller is aligned and free from movement, thus guaranteeing uniform support. The protective roller 4 body is made of rubber with excellent elasticity, which can provide sufficient friction to drive the plate to roll while avoiding hard damage to the plate surface.

[0034] refer to Figure 3 An elastic component 5 is provided on the side of the frame 31 facing away from the protective roller 4. This component consists of a base plate 51 fixed on the frame 31 and an abutment plate 52 connected by multiple sets of springs 53. When the protective roller 4 supports the plate A and bears its huge weight, the entire roller assembly and spindle 312 can undergo a slight adaptive deflection. At the same time, the end of the roller 41 will abut against and compress the elastic abutment plate 52. The buffering effect provided by the springs 53 can provide stable elastic support for the protective roller 4 and prevent damage to the roller 41 or plate A due to rigid collision.

[0035] To facilitate the easy installation and removal of the protective device, refer to Figure 5 and Figure 6 A quick-release connecting buckle 25 is designed at the bottom of the fixed frame 21 of the lifting frame 2. It consists of a slider 251, a pin 252 set on one side of the slider 251, and a pin plate 253 that is inserted and engaged with the pin 252. The pin plate 253 is installed on the frame of the plate rolling machine. Through simple insertion, removal and sliding actions, the entire protective device can be firmly locked on the frame or quickly disassembled, which greatly facilitates the maintenance and cleaning of the equipment or the switching between different workstations, and improves the utilization rate and maintenance efficiency of the equipment.

[0036] Both the linear drive element 32 and the drive mechanism 23 described in this device can be powered by cylinders, which are simple in structure and easy to control and maintain.

[0037] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
