Description

Technical Field

[0001] The utility model relates to the technical field of automobile guide rail processing, in particular to a roller forming device for automobile guide rail processing. Background Art

[0002] With the rapid development of the automobile industry, automobile guide rails, as important automobile parts, are made of metal profiles. Rolling equipment is needed for rolling during production and processing. The spacing between the bottom rollers on both sides of the existing roller press is fixed. In the actual production process of automobile profiles, the bending angles required for profiles of different models of automobiles are different, and the bending chamfer radii are also different. The lower pressing roller of the above-mentioned roller press is also fixedly connected to the lower pressing displacement assembly and cannot be replaced separately. Therefore, it is necessary to prepare multiple roller presses with lower pressing rollers of different sizes, which increases the cost of roller processing.

[0003] A Chinese patent discloses a new type of automobile profile roller press (authorization announcement number CN219851547U). The patented technology uses a mechanical pulling device to pull the card plate to both sides to make it move outward in the through slot, driving the side plate to move outward on the outer wall of the side rod to squeeze the steel spring to generate potential energy, and at the same time, the inner end of the card plate is disengaged from the card slot on both sides of the plug plate, so that the pressure roller can be directly disassembled downward to replace the pressure roller of the required diameter size; twisting the knob drives the second screw head to rotate, and the meshing drives the first screw heads on both sides to rotate synchronously, driving the two The rod body connected to the side rotates, and the outer wall of the rod body connected to the first screw head is provided with threads, which mesh with the threaded holes provided inside the front sleeve plate of the bottom roller, so that the meshing drives the bottom rollers on both sides to move toward or away from each other, and adjusts the spacing between the bottom rollers on both sides. The adjusting rod is twisted to mesh inside the top plate and move downward, driving the cross plate to move vertically downward under the limit of the slide plate embedded in the slide groove, driving the pressing roller to press down the automobile profile placed on the upper side of the bottom roller for pressing processing, so as to facilitate the rapid pressing processing of the profile with different bending chamfer radii, which brings convenience to the pressing roller processing;

[0004] However, it has certain disadvantages: during production and processing, the bottom roller contacts the profile while rotating, which will produce certain vibrations. The vibrations are transmitted to the rod body, causing it to rotate unnecessary due to the vibration, thereby causing unnecessary changes in the distance between the two bottom rollers, making the bending angle of the profile fail to meet the requirements.

[0023] The pressure rod 8 can be rotated to make it rise and fall, and in cooperation with the spring 7, the slider 6 can be driven to rise and fall, thereby adjusting the height of the top pressure roller 5; the threaded rod 11 can be rotated to drive the two movable plates 13 to move toward the middle at the same time, or to move to both sides respectively, thereby adjusting the distance between the two bottom pressure rollers 15; so that the device can meet the different bending angles of the automobile guide rail 22;
