Description

Technical Field

[0001] This utility model relates to the field of metal profile processing technology, and in particular to a high-precision rolling forming equipment. Background Technology

[0002] Existing rolling mill equipment is widely used in the metal profile processing field, mainly for plastic deformation and cross-sectional forming of profiles. Traditional equipment typically includes upper and lower arranged rolls and their drive system, adjusting the distance between the rolls to achieve rolling profiles of different thicknesses. However, such equipment often lacks precise constraints on the lateral position of the profile during rolling, leading to problems such as profile misalignment, torsion, or cross-sectional asymmetry, affecting forming accuracy and product quality. Especially in high-precision applications, such as aerospace and precision instruments, conventional rolling equipment struggles to meet stringent dimensional and positional tolerance requirements. While some improved equipment incorporates lateral limiting devices, they often employ fixed or manually adjustable structures, failing to dynamically adjust the limiting width during production and offering limited flexibility to adapt to different profile specifications. Furthermore, the adjustment of the gap between the upper and lower rolls largely relies on mechanical or hydraulic structures, with limited response speed and accuracy, making it difficult to achieve micron-level high-precision control.

[0003] Therefore, there is an urgent need for a high-precision rolling forming equipment with bidirectional adjustment capability and the ability to achieve coordinated control of the rolling zone and the limiting zone. Utility Model Content

[0004] In view of this, there is an urgent need for a high-precision rolling forming equipment that can achieve bidirectional adjustment capability and coordinated control of the rolling area and the limiting area.

[0005] This application provides a high-precision rolling forming device, including a rolling mechanism and an adjusting mechanism. The rolling mechanism includes a rolling fixed seat, an upper rolling assembly, and a lower rolling assembly. The upper rolling assembly and the lower rolling assembly are both movably disposed within the rolling fixed seat. The adjusting mechanism includes a rolling adjusting assembly, a left limiting assembly, a right limiting assembly, and a limiting adjusting assembly. The rolling adjusting assembly is disposed on the rolling fixed seat and is drively connected to the upper rolling assembly. The left limiting assembly and the right limiting assembly are disposed within the rolling fixed seat. The limiting adjusting assembly is disposed on the rolling fixed seat and is drively connected to the right limiting assembly. A rolling limiting region is formed between the upper rolling assembly, the lower rolling assembly, the left limiting assembly, and the right limiting assembly. The rolling adjusting assembly is used to adjust the distance between the upper rolling assembly and the lower rolling assembly, and the limiting adjusting assembly is used to adjust the distance between the left limiting assembly and the right limiting assembly, so that the rolling limiting region can roll the profile.

[0006] In one embodiment, the rolling mechanism further includes a rolling drive assembly and a rolling transmission assembly. One end of the rolling drive assembly and the rolling transmission assembly are connected in a driving manner, and the upper rolling assembly and the lower rolling assembly are respectively connected in a driving manner to the other end of the rolling transmission assembly. The rolling drive assembly drives the upper rolling assembly and the lower rolling assembly to rotate through the rolling transmission assembly, so that the upper rolling assembly and the lower rolling assembly roll the profile within the rolling limiting area.

[0007] In one embodiment, the rolling drive assembly includes a rolling drive motor, and the rolling transmission assembly includes a reduction gearbox, a first intermediate shaft, and a second intermediate shaft.

One end of the second intermediate shaft is driven to the reduction gearbox via the universal coupling, and the other end of the second intermediate shaft is driven to the lower rolling assembly via the universal coupling. The rolling drive motor drives the upper rolling assembly to rotate via the reduction gearbox and the first intermediate shaft, and the rolling drive motor drives the lower rolling assembly to rotate via the reduction gearbox and the second intermediate shaft, so that the upper and lower rolling assemblies roll the profile within the rolling limit area.

The rolling drive motor drives the upper roller to rotate via a reduction gearbox and the first intermediate shaft, so that the upper die rolls the profile.

[0009] In one embodiment, the lower rolling assembly includes a lower connecting seat, a lower roller, and a lower die. The lower connecting seat is disposed within the rolling fixing seat and located below the upper connecting seat. The lower roller is rotatably disposed at the lower connecting seat. The lower die is sleeved on the outer surface of the lower roller. A rolling area is formed between the upper die and the lower die. The rolling drive motor drives the lower roller to rotate through a reduction gearbox and the second intermediate shaft, so that the lower die cooperates with the upper die to roll the profile.

[0010] In one embodiment, the rolling adjustment assembly includes an adjustment drive motor, an adjustment transmission device, and a transmission screw. The adjustment drive motor and the adjustment transmission device are fixed to the upper end of the rolling fixed seat, and the adjustment drive motor is drively connected to the adjustment transmission device. The transmission screw is movably mounted on the adjustment transmission device, and the lower end of the transmission screw is fixedly connected to the upper connecting seat. The adjustment drive motor drives the transmission screw to move up and down via the adjustment transmission device, thereby causing the upper connecting seat to shift relative to the lower connecting seat within the rolling fixed seat, thus adjusting the size of the rolling area.

[0011] In one embodiment, the left limiting assembly includes a left connecting seat and a left limiting roller, and the right limiting assembly includes a right connecting seat and a right limiting roller. Both the left and right connecting seats are located within the rolling fixing seat and within the rolling area. The left limiting roller is rotatably mounted on the left connecting seat, and the right limiting roller is rotatably mounted on the right connecting seat. A limiting area is formed between the left and right limiting rollers, and the intersection of the limiting area and the rolling area forms the rolling limiting area. The left and right limiting rollers are used to limit the relative position of the profile within the rolling area, so that the upper and lower dies can precisely roll the profile.

[0012] In one embodiment, the limit adjustment assembly includes a limit drive motor, a limit transmission device, and a transmission push rod.

The transmission push rod is movably mounted on the limit transmission device, and the left end of the transmission push rod is fixedly connected to the right connecting seat. The limit drive motor drives the transmission push rod to move left and right through the limit transmission device, thereby causing the right connecting seat to move relative to the left connecting seat within the rolling fixed seat, thus adjusting the size of the limit area.

[0013] The high-precision rolling forming equipment provided by this utility model has the following significant advantages:

[0014] 1. High rolling precision: Through independently controlled rolling adjustment components and limit adjustment components, the spacing between the upper and lower rolls (rolling area) and the spacing between the left and right limit rollers (limiting area) can be precisely adjusted to form a stable rolling limit area, effectively preventing the profile from shifting or deforming during the rolling process, and ensuring high consistency of the formed cross-sectional dimensions and shape.

[0015] 2. High flexibility: The motor-driven adjustment method supports dynamic adjustment of the rolling zone and the limit zone, which can adapt to the processing of profiles with different cross-sectional dimensions without stopping the machine, significantly improving production efficiency and the applicability of the equipment.

[0016] 3. Stable and reliable transmission structure: The rolling drive assembly transmits power to the upper and lower rollers through a reduction gearbox and universal coupling, ensuring synchronous rotation and smooth torque transmission; the adjustment mechanism adopts screw or push rod transmission, which has high positioning accuracy and strong anti-interference ability, and is suitable for high-intensity continuous rolling conditions. High degree of automation: The adjustment drive motor and limit drive motor can be integrated with an external control system to realize digital parameter setting and remote control, reduce human operation errors, and meet the needs of intelligent production lines.

[0017] 4. Compact structure and easy maintenance: The modular arrangement of each component within the rolling fixed seat maximizes space utilization, and key transmission components (such as universal couplings and screws) are easy to disassemble and replace, reducing equipment maintenance costs.

[0018] In summary, this utility model achieves precise control of the profile rolling process by integrating a rolling and limiting dual adjustment system, which is especially suitable for the mass production of high-precision, multi-specification profiles, and significantly improves production efficiency while enhancing product quality.

The upper rolling assembly 12 and the lower rolling assembly 13, the left limiting assembly 22 and the right limiting assembly 23 are disposed within the rolling fixed seat 11, and the limiting adjustment assembly 24 is disposed on the rolling fixed seat 11 and is connected to the right limiting assembly 23 in a transmission manner.

[0027] It should be noted that this configuration, by employing the upper rolling assembly 12, lower rolling assembly 13, left limiting assembly 22, and right limiting assembly 23 in cooperation to form a rolling limiting area, achieves the functions of limiting and rolling the profile. Furthermore, the rolling adjustment assembly 21 is used to adjust the position of the upper rolling assembly 12, and the limiting adjustment assembly 24 is used to adjust the position of the right limiting assembly 23, thereby achieving precise adjustment of the rolling limiting area, making the rolling limiting area precisely matched with the profile, and improving the accuracy of profile rolling.
