Description

Technical Field

[0001] The present application relates to the technical field of rolling machines, and in particular to an auxiliary device for a rolling machine. Background Art

[0002] A rolling machine, also known as a rolling round machine, is a metal processing equipment mainly used for curling flat or straight metal profiles (such as flat steel, square steel, round steel, angle steel, channel steel, etc.) into circular or arc shapes to make various pipes, cylinders, containers and other items. It is widely used in industries such as petroleum, chemical industry, shipbuilding, hydropower, metal structure and machinery manufacturing.

[0003] In the related art, the structure of a profile rolling machine usually includes parts such as a machine body, a roller system, a transmission system, and a control system. Among them, the roller system is the core component, which consists of a driving roller, a driven roller (or a pressure roller), etc. The transmission system is responsible for transmitting power to the rollers to make them rotate. The control system is used to adjust parameters such as the position, speed and pressure of the rollers to control the curling accuracy and shape of the profiles.

[0004] In view of the above related art, when the rolling machine processes profiles with a small diameter, the rolling forming effect is good. However, when rolling profiles with a large diameter (3 - 5m) after forming, due to problems such as uneven internal material and stress of the profiles, problems such as unqualified dimensions after rolling are likely to occur, and the profile forming effect is poor. Content of the Utility Model

[0005] In order to improve the problem of unqualified dimensions of large - diameter profiles after rolling and improve the profile forming effect, the present application provides an auxiliary device for a rolling machine.

[0006] The auxiliary device for a rolling machine provided by the present application adopts the following technical solutions:

[0007] An auxiliary device for a rolling machine includes a base arranged on one side of the machine body, a fixed auxiliary mechanism and a sliding auxiliary mechanism arranged on the upper side of the base and arranged oppositely. A rolling gap for the profile to pass through is left between the sliding auxiliary mechanism and the fixed auxiliary mechanism. The base is provided with a guide rail seat for the sliding auxiliary mechanism to slide, and the base is provided with a driving component for driving the sliding auxiliary mechanism to approach / away from the fixed auxiliary mechanism;

[0008] Both the fixed auxiliary mechanism and the guide rail seat are inclined and installed on the base, and the included angles between the length directions of the fixed auxiliary mechanism and the guide rail seat and the length direction of the base are the same.

[0009] By adopting the above technical solutions, a fixed auxiliary mechanism and a sliding auxiliary mechanism are added, and a rolling round gap is formed between them, which can provide additional support and guidance during the profile curling process, helping to evenly distribute the stress and material inside the profile, reducing deformation caused by uneven stress, and thus improving the precision and consistency of the round rolling. The driving assembly can drive the sliding auxiliary mechanism to approach or move away from the fixed auxiliary mechanism, thereby adjusting the size of the rolling round gap to adapt to profiles of different diameters. This adjustability enables the auxiliary device to be widely applied to the processing of various specifications of profiles, improving the versatility and flexibility of the equipment. The fixed auxiliary mechanism and the guide rail seat are both inclinedly installed on the base, and the angles between them and the length direction of the base are the same, which helps to achieve a smoother transition and a more uniform force distribution during the profile curling process. The setting of the inclination angle can be adjusted based on the specific profile material and curling requirements to achieve the best forming effect. Since this auxiliary device can improve the forming effect of the profile and reduce rework and waste caused by unqualified dimensions, it can significantly improve the processing efficiency of the round rolling machine.

[0010] Furthermore, an installation base plate is provided on the upper side of the base. The fixed auxiliary mechanism is fixedly connected to one side of the base plate, and the guide rail seat is fixedly connected to the base plate and is located on the opposite side of the fixed auxiliary mechanism. A sliding block for installing the sliding auxiliary mechanism is slidably installed on the guide rail seat.

[0011] By adopting the above technical solutions, the installation base plate serves as an intermediate connection layer, providing a more stable support for the fixed auxiliary mechanism and the guide rail seat, reducing loosening or deformation caused by uneven force or vibration during the round rolling process. Installing both the fixed auxiliary mechanism and the guide rail seat on the base plate makes the installation and disassembly process simpler and faster. Since both the fixed auxiliary mechanism and the guide rail seat are fixed on the base plate and their relative positions are precisely set, it can ensure that the sliding auxiliary mechanism can slide along the guide rail seat during the processing, thereby forming an accurate rolling round gap with the fixed auxiliary mechanism, which is beneficial to improving the round rolling precision of the profile.

[0012] Furthermore, the fixed auxiliary mechanism / the sliding auxiliary mechanism includes a U-shaped fixed seat, a rotating shaft passing through the U-shaped fixed seat, and a roller rotatably connected to the rotating shaft and used to abut against the side wall of the profile;

[0013] A connecting block is fixedly connected to the U-shaped positioning seat of the sliding auxiliary mechanism, and the connecting block is fixedly connected to the sliding block.

[0014] By adopting the above technical solutions, both the fixed auxiliary mechanism and the sliding auxiliary mechanism adopt a combined structure of a U-shaped fixing seat, a rotating shaft and a roller, enabling the auxiliary mechanism to flexibly adapt to profiles of different shapes and sizes. The U-shaped fixing seat provides a stable support for the roller, making it difficult for the roller to deviate or shake during rotation. The rotating shaft rotatably connects the roller to the U-shaped fixing seat, ensuring that the roller can maintain close contact with the side wall of the profile during the curling process of the profile, which helps to improve the curling accuracy and forming effect of the profile. A connecting block is fixedly connected to the positioning seat of the sliding auxiliary mechanism, and the connecting block is fixedly connected to the sliding block, enabling the sliding auxiliary mechanism to be installed on the guide rail seat and smoothly slide on the guide rail seat through the sliding block, simplifying the installation process and improving the installation accuracy and stability.

[0015] Further, the driving mechanism includes a driving cylinder and two fixed side plates. The driving cylinder is arranged on the side of the guide rail seat away from the fixed auxiliary mechanism. The two fixed side plates are vertically arranged and symmetrically fixedly connected to both sides of the guide rail seat. Both fixed side plates are fixedly connected to the cylinder body of the driving cylinder, and a through hole matching the piston rod of the driving cylinder is formed in the connecting block.

[0016] By adopting the above technical solutions, the driving cylinder serves as a power source, providing stable and controllable thrust or pull force, thereby driving the sliding auxiliary mechanism to smoothly slide along the guide rail seat. The driving cylinder has a simple structure, reliable operation, and is easy to control, being suitable for occasions that require precise control of position and speed. The driving cylinder is arranged on the side of the guide rail seat away from the fixed auxiliary mechanism, and the two fixed side plates are vertically arranged and symmetrically fixedly connected to both sides of the guide rail seat, making the entire driving mechanism compact and reasonable in structure, saving space, and helping to improve the overall stability and reliability of the equipment. The fixed side plates are fixedly connected to the guide rail seat, and the cylinder body of the driving cylinder is fixedly connected to the fixed side plates, simplifying the installation process of the driving mechanism. A through hole matching the piston rod of the driving cylinder is formed in the connecting block, facilitating the connection and positioning of the piston rod and the sliding auxiliary mechanism.

[0017] Further, the rotating shaft is detachably connected to the U-shaped fixing seat. The U-shaped fixing seat has an installation hole for the rotating shaft to pass through, and a limiting sealing plate is arranged on the upper side of the U-shaped fixing seat. The diameter of the limiting sealing plate is larger than the diameter of the installation hole.

[0018] By adopting the above technical solution, the rotating shaft and the U-shaped fixing seat are detachably connected, so that when the roller is worn or needs to be replaced, the rotating shaft and the roller can be easily removed without replacing the entire U-shaped fixing seat, thereby reducing maintenance costs and time and improving the maintainability of the equipment. The U-shaped fixing seat is provided with a mounting hole for the rotating shaft to pass through, ensuring the precise positioning of the rotating shaft during the installation process. The diameter of the mounting hole matches the diameter of the rotating shaft, so that the gap and error during the installation process can be reduced and the installation accuracy can be improved. The U-shaped fixing seat is provided with a limiting sealing plate on the upper side, and the diameter of the limiting sealing plate is larger than the diameter of the mounting hole, so as to prevent the rotating shaft from falling off or loosening from the mounting hole, thereby enhancing the connection stability between the U-shaped fixing seat and the rotating shaft. The limiting sealing plate can also play a certain limiting role on the rotating shaft to prevent it from shifting or shaking during operation.

[0019] Furthermore, the installation base plate is provided with a plurality of pre-opened holes at intervals for the auxiliary fixing mechanism to adjust the installation position.

[0020] By adopting the above technical solution, the opening of the pre-opening allows the operator to adjust the position of the fixing auxiliary mechanism on the mounting base plate according to actual needs, so that the auxiliary device can adapt to the processing requirements of profiles of different diameters, lengths or shapes, thereby improving the versatility and adaptability of the equipment.

[0021] Furthermore, there are a plurality of rollers, and the rollers are arranged in parallel along the length direction of the rotating shaft.

[0022] By adopting the above technical solution, increasing the number of rollers and arranging them in parallel along the length direction of the rotating shaft, the support stability of the fixed auxiliary mechanism and the sliding auxiliary mechanism on the profile can be improved. Multiple rollers can more evenly disperse the pressure generated by the profile during the curling process to prevent deformation or damage caused by excessive force on a single point. The number and arrangement of rollers directly affect the curling effect of the profile. Multiple rollers can fit the side wall of the profile more closely, reduce the gap and error during the processing, and thus improve the processing accuracy and quality of the finished product. At the same time, the parallel arrangement of the rollers also helps to maintain the stability and consistency of the profile during the curling process.

[0023] Furthermore, the base includes an L-shaped connecting plate for connecting to the machine body and a supporting angle block arranged on the lower side of the L-shaped connecting plate, and the mounting base plate is detachably connected to the upper side of the L-shaped connecting plate.

[0024] By adopting the above technical solution, the L-shaped connecting plate enables the base to be more firmly connected to the machine body. The L-shaped structure provides a larger contact area and stronger supporting force to prevent the auxiliary device from shaking or falling off during the processing. The supporting angle block is arranged on the lower side of the L-shaped connecting plate to provide additional support for the entire auxiliary device. The supporting angle block disperses and bears the gravity and impact force generated by the auxiliary device during the processing to prevent the base from deformation or damage. The mounting base plate and the L-shaped connecting plate are detachably connected. This design allows the user to easily install or remove the mounting base plate as needed. When it is necessary to replace or maintain components such as rollers, it is only necessary to remove the mounting base plate without disassembling the entire auxiliary device, thereby improving the convenience and efficiency of maintenance.

[0025] Furthermore, the base is provided with a limiting step along the length direction on the side close to the body, and the base is provided with a limiting strip parallel to the limiting step on the edge away from the limiting step, and the mounting base plate is abutted between the limiting step and the limiting strip.

[0026] By adopting the above technical solution, a limiting step is set along the length direction on the side of the base close to the body, and a limiting strip parallel to the limiting step is set on the edge on the side away from the limiting step, thereby providing a precise installation position for the installation base plate. The installation base plate can be tightly abutted between the two limiting structures, thereby ensuring the accuracy and stability of the installation, and helping to reduce processing errors and safety hazards caused by inaccurate installation position.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Adding a fixed auxiliary mechanism and a sliding auxiliary mechanism, and forming an adjustable rolling gap between the two, provides additional support and guidance during the curling process of the profile, helps to evenly distribute the stress and material inside the profile, and reduces the deformation caused by uneven stress, thereby significantly improving the accuracy and consistency of curling. The size of the rolling gap can be adjusted by the drive component to adapt to profiles of different diameters, so that the auxiliary device can be widely used in the processing of profiles of various specifications, improving the versatility of the equipment;

[0029] 2. The guide rail seat and fixed side plate provide precise sliding tracks for the sliding auxiliary mechanism, ensuring the smoothness and accuracy of the sliding process;

[0030] 3. The roller and the U-shaped fixing seat ensure the stability and precision of the roller during rotation, prevent deviation or shaking, enhance the reliability of the overall structure. The U-shaped fixing seat is detachably connected to the rotating shaft, facilitating the replacement and maintenance of the roller, reducing the maintenance cost and time, and improving the maintainability of the equipment. The rollers are arranged side by side along the length direction of the rotating shaft, and multiple rollers can fit more closely to the side wall of the profile, reducing the processing gap and error, and further enhancing the processing precision and the quality of the finished product.

Detailed Description of the Embodiment

[0037] In order to make the purpose, technical solutions and advantages of the present application clearer and more understandable, the following Figures 1-5 in combination with the attached

[0038] and embodiments, the present application will be further described in detail. Figure 1 and Figure 2, The auxiliary device of the rolling machine is arranged on one side of the body of the rolling machine. The auxiliary device of the rolling machine includes a base, a fixed auxiliary mechanism and a sliding auxiliary mechanism. The base is installed on the side wall of the body and is flush with the upper side of the body. The fixed auxiliary mechanism and the sliding auxiliary mechanism are both arranged on the upper side of the base and are arranged oppositely. There is a rolling gap between the sliding auxiliary mechanism and the fixed auxiliary mechanism. After the profile passes through the body, it enters the rolling gap for auxiliary rolling, thereby improving the rolling forming effect.

[0039] Referring to Figure 2 and Figure 3 , the base includes an L-shaped connecting plate and a supporting angle block. One side of the L-shaped connecting plate is fixedly connected to the side wall of the body, and the supporting angle block supports the lower side of the L-shaped connecting plate and is fixedly connected to the L-shaped connecting plate. The L-shaped connecting plate is provided with a mounting base plate for installing the fixed auxiliary mechanism and the sliding auxiliary mechanism. A limiting step is arranged along the length direction on the upper side of the L-shaped connecting plate near the body, and a limiting strip is vertically arranged and fixedly connected on the upper side of the L-shaped connecting plate away from the limiting step. The mounting base plate abuts between the opposite side surfaces of the limiting step and the limiting strip, and the bottom side of the mounting base plate and the L-shaped mounting plate are detachably connected through fixing parts such as bolts.

[0040] Referring to Figure 3 and Figure 4 , the fixed auxiliary mechanism is fixedly connected to the side of the mounting base plate close to the body. Three pre-opened holes for installing the fixed auxiliary mechanism are opened on the mounting base plate. A guide rail seat is fixedly connected to the mounting base plate at a position opposite to the fixed auxiliary mechanism, and a sliding block for installing the auxiliary connecting mechanism is slidably mounted above the guide rail seat.

[0041] A driving assembly for driving the sliding auxiliary mechanism is arranged on the side of the guide rail seat away from the fixed auxiliary mechanism. The driving assembly includes a driving cylinder and two fixed side plates. The two fixed side plates are symmetrically arranged and are both vertically fixedly connected to both sides of the guide rail seat. The cylinder body of the driving cylinder is fixedly connected between the two fixed side plates.

[0042] Referring to Figure 3 and Figure 5 , both the fixed auxiliary mechanism and the sliding auxiliary mechanism include a U-shaped fixing seat, a rotating shaft and a roller.

[0043] The installation method of the fixed auxiliary mechanism is specifically as follows: the U-shaped fixing seat is vertically fixedly connected to the mounting base plate through the pre-opened hole. The U-shaped fixing seat is provided with a mounting hole, the rotating shaft passes through the mounting hole and is fixedly connected to the U-shaped fixing seat, and the roller is rotatably connected to the rotating shaft and is used to abut against the side wall of the profile.

[0044] In this embodiment, the number of rollers is preferably two, and the two rollers are arranged side by side along the length direction of the rotating shaft. The setting of the double rollers can evenly disperse the pressure generated during the curling process of the profile, preventing deformation or damage caused by excessive single-point stress.

[0045] The U-shaped fixing base is provided with a limiting sealing plate on the upper side, and the diameter of the limiting sealing plate is larger than the diameter of the installation hole, thereby preventing the rotating shaft from disengaging from the installation hole. The limiting sealing plate is fixed to both the U-shaped fixing base and the rotating shaft by means of threaded connections.

[0046] The difference between the sliding auxiliary mechanism and the fixing auxiliary mechanism lies in that: the U-shaped positioning base of the sliding auxiliary mechanism is provided with a connecting block, and the connecting block is fixedly connected to the side of the U-shaped positioning base away from the fixing auxiliary mechanism. The connecting block is fixedly connected to the upper side of the sliding block, and a through hole is formed in the side wall of the connecting block away from the U-shaped positioning base, and the piston rod of the driving cylinder is inserted into the through hole and fixedly connected to the connecting block.

[0047] The implementation principle of an auxiliary device for a rolling machine in an embodiment of the present application is as follows: The base is stably installed on the side wall of the rolling machine body through an L-shaped connecting plate and is flush with the upper side of the body. The supporting angle block is arranged under the L-shaped connecting plate to provide additional supporting force to ensure the stability of the base. The installation base plate is detachably connected to the L-shaped connecting plate through fixing parts such as bolts, and is accurately limited by a limiting step and a limiting strip to ensure the accuracy and stability of the installation position. The fixing auxiliary mechanism is vertically fixed to the side of the installation base plate close to the body through a pre-opened hole and includes a U-shaped fixing base, a rotating shaft and a roller. The roller is rotatably connected to the U-shaped fixing base through the rotating shaft and is used to abut against the side wall of the profile to provide support and guidance. The sliding auxiliary mechanism is installed on the guide rail seat through a sliding block and can smoothly slide along the guide rail seat. Its structure is similar to that of the fixing auxiliary mechanism, but a connecting block is added for connecting with the piston rod of the driving cylinder to realize the sliding function. The sliding auxiliary mechanism is driven by a driving component (such as a driving cylinder) and can approach or move away from the fixing auxiliary mechanism, thereby adjusting the rolling gap between the two. This adjustability enables the auxiliary device to adapt to the processing requirements of profiles with different diameters.

[0048] After the profile is preliminarily processed in the body of the rolling machine, it enters the rolling gap formed by the fixing auxiliary mechanism and the sliding auxiliary mechanism. During this process, the rollers of the fixing auxiliary mechanism and the sliding auxiliary mechanism are in close contact with the side wall of the profile, providing additional support and guidance, which helps to evenly distribute the stress and material inside the profile and reduce deformation caused by uneven stress. The sliding auxiliary mechanism adjusts its position according to the diameter of the profile and the processing requirements through the driving component to ensure the appropriate size of the rolling gap, thereby realizing high-precision rolling forming. Due to the detachable connection between the installation base plate and the L-shaped connecting plate, as well as the detachable design between the U-shaped fixing base and the rotating shaft, the replacement and maintenance of vulnerable parts such as rollers become simple and fast, reducing the maintenance cost and time.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
