Description

Technical Field

[0001] The utility model relates to a bending preforming structure and a side plate bending forming mechanism. Background Art

[0002] The side panels are generally made using profile forming equipment, which can gradually process strip-shaped and straight materials into the required profile structure, generally in the shape of a long U-shaped groove. The above-mentioned profile forming equipment generally includes several groups of forming wheel groups arranged in sequence for forming, and some guide wheel groups are also arranged between the forming wheel groups to guide the materials. At present, the forming equipment on the market often has a relatively simple structure, and the installation of each component is relatively fixed, especially the guide wheel group, which is difficult to fine-tune as a whole, resulting in deviations in the size of the product after forming, or the product has a large forward resistance during forming, and obvious extrusion marks, pull marks or scratches will appear on the periphery of the product. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an adjustment structure and a side panel bending and forming mechanism which can reduce the scratches on the periphery of the side panel product.

[0004] A bending preforming structure comprises a seat body and a preforming component mounted on the seat body, wherein the preforming component comprises a distance adjustment structure and two guide wheels;

[0005] The distance adjustment structure comprises a screw and a guide seat; the screw is rotatably mounted on the seat body, there are two guide seats, the guide seats are slidably mounted on the seat body, the guide seat is provided with a horizontal shaft hole and a vertical shaft hole, the screw passes through the horizontal shaft hole, and the wheel axles of the guide wheels respectively pass through the vertical shaft holes;

[0006] The two ends of the screw rod are provided with screw teeth in opposite directions, the horizontal shaft hole is provided with threads, the two guide seats can move in opposite directions, and thus the distance between the two guide wheels is adjustable, which can be applicable to profiles of various widths.

[0007] The circumference of the guide wheel is an inclined surface, and the top diameter of the guide wheel is larger than the bottom diameter. When in use, the two guide wheels with inclined surfaces can press the side panels down to prevent them from tilting, and further clamp the two sides thereof, and further bend them in advance to avoid collision and scratches caused by the large difference in the molding profile size with the molding wheel group when entering the next group of molding wheels, which helps to improve the molding accuracy and quality of the side panels.

[0008] Preferably, the slope of the inclined surface of the guide wheel is 0.5°-1°.

[0009] Preferably, the seat body includes a support seat, a mounting seat, a screw hole, a limiting slot and a screw; the mounting seat or the support seat is provided with a longitudinal strip hole, and the mounting seat is mounted on the support seat by means of a bolt and the strip hole; the screw hole is arranged on one side of the mounting seat, the limiting slot is arranged on the top of the support seat and close to the opening of the screw hole, the screw is screwed into the screw hole, and the lower part of the head is limited in the limiting slot, and the mounting seat is adjusted in its mounting position on the support seat by the rotation of the screw. During use, when the operator rotates the screw, the screw will not move as a whole because the head of the screw is limited in the limiting slot. At this time, the rotation of the screw will be converted into the movement of the mounting seat on the support seat, thereby realizing the position adjustment of the mounting seat (to make it located at the center of the production line), and the adjustment can be slight and has high precision.

[0010] Preferably, the mounting seat is provided with a longitudinal slide rail, and the bottom of the guide seat is mounted on the longitudinal slide rail via a sliding block.

[0013] The bending preforming structures also have several groups, and the bending preforming structures and the forming wheel groups are staggeredly arranged on the frame;

[0014] The driving assembly is installed on the frame and is connected to drive the forming wheels of each forming wheel group to rotate.

[0015] Preferably, the screw rod is mounted on the mounting seat via a bearing seat, an adjusting head is provided at one end of the screw rod, and anti-slip patterns are provided on the periphery of the adjusting head for easy adjustment.

[0016] Preferably, each group of the forming wheel sets comprises an upper forming wheel and a lower forming wheel, and the upper forming wheel of the first group of the forming wheel sets has two convex ribs arranged at intervals.

[0017] From the above description of the utility model, it can be seen that the utility model has the following beneficial effects:

[0018] 1. The circumferential surface of the guide wheel of the bending preforming structure of the utility model is an inclined surface, and the top diameter of the guide wheel is larger than the bottom diameter. When in use, the two guide wheels with inclined surfaces can press the side panels down to prevent them from tilting, and further clamp the two sides thereof, and further bend them in advance to avoid collision and scratches caused by the large difference in the forming profile size with the forming wheel group when entering the next forming wheel group, which helps to improve the forming accuracy and quality of the side panels;

[0019] 2. The bending preforming structure of the utility model can fine-tune the relative installation position between the support seat and the mounting seat, which can make the guidance of the profile more accurate, avoid the distortion and deformation of the profile during the transportation process, and at the same time, can also reduce the noise generated during the side panel forming process;

[0020] 3. The seat body is adjusted by a screw with the screw head restricted, forming an adjustment mechanism with simple structure, easy operation and high adjustment accuracy;

[0021] 4. The upper forming wheel of the first forming wheel group has two convex ribs arranged at intervals. The first forming wheel group can pre-fold grooves on the profile, which is convenient for the subsequent gradual forming of the folding plates on both sides, and can also avoid the rounded corners of the bent part of the side plate being too large, and at the same time facilitate the bending of the side edges with lower height.

[0036] The circumferential surface of the guide wheel 36 is an inclined surface 361, and the top diameter of the guide wheel 36 is larger than the bottom diameter. When in use, the two guide wheels 36 with inclined surfaces 361 can press the side panels downward to prevent them from tilting, and further clamp the two sides thereof, and further bend them in advance to avoid collision and scratches due to the large difference in the molding profile size with the molding wheel set 2 when entering the next set of molding wheel sets 2, which helps to improve the molding accuracy and quality of the side panels.
