Technical Field

The utility model relates to the technical field of cold roll forming, in particular to a pressure wheel structure for a cold roll forming machine.

Background Art

Aluminum alloy doors and windows are doors and windows made of aluminum alloy extruded profiles as frames, stiles, and sashes. Aluminum alloy doors and windows have the advantages of good sealing performance, excellent weather resistance, long service life, strong plasticity, and large opening range. When processing aluminum alloy door and window profiles, the aluminum alloy needs to be cold-bent;

Cold roll forming is a plastic processing technology that uses multiple forming rollers configured in sequence to continuously bend metal sheets such as coils and strips horizontally to form profiles with specific cross-sections. Cold roll forming is a new process and technology for metal sheet forming that saves materials, energy and is efficient. Using this process, not only can high-quality steel products be produced, but also the product development cycle can be shortened, production efficiency can be improved, thereby enhancing the company's market competitiveness. Press wheels are required during cold roll forming processing.

For example, Chinese patent publication number CN220049594U discloses a pressure wheel structure for a cold bending forming machine, including a first wheel axle and a second wheel axle with axes parallel to each other, two first pressure wheels are arranged on the first wheel axle along its axial direction, and a second pressure wheel is arranged on the second wheel axle located between the two first pressure wheels, the first wheel axle and the second wheel axle are connected to each other through a positioning bracket structure, and an axis adjustment sleeve is arranged at the central axis of the two first pressure wheels, the axis adjustment sleeve is slidably sleeved on the outer side of the first wheel axle, and a tightening bolt for abutting and tightening with the first wheel axle is threadedly connected on the outer side wall of the axis adjustment sleeve, so that the position of the two first pressure wheels on the first wheel axle can be adjusted, so as to achieve adjustment of the pressing width size, and the second pressure wheel is located between the two first pressure wheels, and after the two first pressure wheels press the door panel to form, the second pressure wheel can fill the gap between the two first pressure wheels to avoid bulges caused by omissions.

Although the above example can adjust the distance between the pressure wheels when processing the aluminum alloy profile, when the pressure wheels are fixed, the pressure wheels are only fixed by the friction between the bolts and the rotating shaft, and the surface of the rotating shaft is relatively smooth. When the pressure wheels are subjected to excessive force when rolling the aluminum alloy profile, they are prone to slipping, thereby causing the aluminum alloy profile processing to fail, which is inconvenient to use. At the same time, when the aluminum alloy profile needs to be bent into an inclined surface, a pointed wheel with different inclined surfaces is also required. The existing pressure wheel structure only has one type of pressure wheel. During processing, the pressure wheels need to be frequently removed and replaced, which is inconvenient to use.

In this embodiment, when the aluminum alloy profile is cold-bent, the pressure wheel structure is installed on the cold-bending machine by the fixing screws 12, and then the aluminum alloy profile is cold-bent. During the cold-bending process, the fixing nuts 26 are rotated to make the fixing nuts 26 at both ends of the rotating sleeve 23 move along the threaded rod 25, and at the same time drive the rotating sleeve 23 to slide along the sliding rod 22, thereby adjusting the position of the flat pressure wheel 24. After adjusting to the appropriate position, the fixing nut 26 on one side is rotated to make the fixing nut 26 squeeze and fix the rotating sleeve 23, thereby fixing the flat pressure wheel 24.

In this embodiment, after lowering the position of the pointed pressure wheel assembly 37, the rotating wheel 311 is rotated so that the threaded rod 310 drives the block 312 to engage with the fixed tooth 38, thereby reinforcing the adjustment bracket 31 to prevent the pointed pressure wheel assembly 37 from moving up during the cold bending process, making it easier to use.

The following is a detailed description of the working principle of the pressure wheel structure for the cold roll forming machine.

As shown in Figures 1-4, when the aluminum alloy profile is cold-bent, the pressure wheel structure is installed on the cold-bent forming machine by fixing screws 12, and then the aluminum alloy profile is cold-bent. During the cold-bending process, the fixing nuts 26 are rotated to make the fixing nuts 26 at both ends of the rotating sleeve 23 move along the threaded rod 25, and at the same time drive the rotating sleeve 23 to slide along the sliding rod 22, so as to adjust the position of the flat pressure wheel 24. After adjusting to the appropriate position, the fixing nut 26 on one side is rotated to make the fixing nut 26 squeeze and fix the rotating sleeve 23, so as to fix the flat pressure wheel 24. The fixing method of the fixing nut 26 can effectively prevent the pressure wheel from being displaced when the force is too large, so that the fixing effect of the pressure wheel is better, and when the inclined surface needs to be processed When the screw sleeve 33 is rotated, the screw sleeve 33 moves downward under the action of the rotation of the screw sleeve 33, and the screw rod 22 is driven to retract into the screw sleeve 33, thereby reducing the position of the adjustment bracket 31, and then the pointed pressure wheel assembly 37 is lowered than the flat pressure wheel 24, so that the flat pressure wheel 24 cannot contact the surface of the aluminum alloy profile, so that the pointed pressure wheel assembly 37 can bend the aluminum alloy profile into an inclined surface, so that there is no need to frequently replace the pressure wheel during the cold bending process. At the same time, after lowering the position of the pointed pressure wheel assembly 37, the rotating wheel 311 is rotated to make the threaded rod 4 310 drive the block 312 to engage with the fixed tooth 38, so as to reinforce the adjustment bracket 31 and prevent the pointed pressure wheel assembly 37 from moving up during the cold bending process, making it more convenient to use.

The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
