Description

Technical Field

[0001] The utility model relates to a cold bending forming mechanism, in particular to a vertical roller adjustable cold bending forming mechanism. Background Art

[0002] Cold roll forming technology is a new technology for metal sheet forming that is energy-saving, energy-saving and efficient. It is a plastic processing technology that continuously bends metal sheets such as coils and strips horizontally through sequentially configured multi-pass forming rollers to form profiles with specific cross-sections. Since cold roll forming technology can integrate multiple processes such as welding, stamping, online arc forming and cutting, it has high production efficiency and has obvious advantages over other technologies. It has good market competitiveness and has been widely used in the industrial field. Generally, the control of cold roll section requires the use of vertical rollers to assist in forming while rolling, which plays the role of rebound control, finishing forming, guiding, and avoiding rollers from indenting or scratching the profile. When the vertical roller assists in forming, the vertical roller needs to apply pressure to the side of the profile. Therefore, when forming profiles of different cross-sections, the height and center span of the vertical roller need to be adjusted to make it suitable for the cross-section design requirements of the profile to be formed.

[0003] At present, the vertical roller is fixed on the crossbeam connecting the lower part of the two roller brackets by multiple bolts. The two vertical rollers are fixed separately and relatively independent. When adjusting their positions, it is necessary to unscrew the bolts on one side and shift the vertical roller on one side separately. After tightening, unscrew the bolts on the other side and adjust the vertical roller on the other side separately. The adjustment process is cumbersome and laborious. In addition, due to the independent adjustment of the two vertical rollers and their poor symmetry, it is easy to have asymmetric center spans or misalignment of the axes of the left and right vertical rollers. It often takes multiple precise adjustments to achieve basic consistency, which is time-consuming and laborious. Therefore, how to simplify the adjustment operation of the operators and improve the symmetry of the adjustment positions of the two vertical rollers has become a problem that needs to be solved at present.

DETAILED DESCRIPTION

[0021] The utility model will be further described below in conjunction with the accompanying drawings.

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0023] The directions or their approximate terms described throughout the present invention, such as "front", "rear", "left", "right", "upper (top)", "lower (bottom)", "inside", "outside", "side", etc., are mainly with reference to the directions of the drawings. Each direction or its approximate terms are only used to assist in the explanation and understanding of the embodiments of the present invention, and are not used to limit the present invention.

[0024] A vertical roller adjustable cold roll forming mechanism, such as Figure 1 , Figure 2 As shown, it includes two roller brackets 18 arranged opposite to each other, a group of horizontal rollers 2 are arranged on the roller brackets 18, the two horizontal rollers 2 are arranged up and down, the roller axes of the horizontal rollers 2 extend laterally and are assembled and connected with the bearing seats fixed on the roller brackets 18; the cold-bent profile 1 is roll-formed between the two horizontal rollers 2. A vertical roller 17 is respectively arranged on the left and right sides of the cold-bent profile 1 to assist in forming the profile 1.

[0025] like Figure 1 As shown, the vertical roller 17 is rotatably installed in the adjustment frame. The adjustment frame is a rectangular frame surrounded by an upper horizontal plate 3, a lower horizontal plate 4, a front vertical plate 6, a rear vertical plate 19, and a side plate 16. The adjustment frame opening close to the side of the profile 1 allows the vertical roller 17 to directly contact the side of the profile 1 and apply pressure. In the adjustment frame, the surface of the vertical roller 17 does not directly contact any plate surface; the mandrel of the vertical roller 17 is equipped with an upper horizontal plate 3, an upper bearing, a vertical roller 17, a lower bearing, and a lower horizontal plate 4 from top to bottom, so that the vertical roller 17 can rotate flexibly in the adjustment frame. The upper horizontal plate 3 and the lower horizontal plate 4 are respectively mounted on the upper end and the lower end of the mandrel to limit the vertical direction of the vertical roller 17.

[0026] A connecting block 15 is also arranged between the side plate 16 and the roller bracket 18, and the connecting block 15 is fixed to the outside of the side plate 16. The outer side of the roller bracket 18 is fixedly connected to the screw mounting plate 12, and the screw mounting plate 12 and the connecting block 15 are arranged opposite to each other. The screw mounting plate 12 is provided with a screw hole, and an adjusting screw 13 is installed in the screw hole. One end of the adjusting screw 13 passes through the screw mounting plate 12 and the roller bracket 18, and is fixedly connected to the connecting block 15, and the other end of the adjusting screw 13 is locked and fixed by a screw locking nut 14. Through the threaded cooperation between the adjusting screw 13 and the screw mounting plate 12, when the adjusting screw 13 is rotated, the adjusting screw 13 drives the adjusting frame to extend and retract synchronously, so as to adjust the position of the vertical roller 17 in the horizontal direction. The adjusting screws 13 on both sides are arranged symmetrically, and the positions of the adjusting frames on both sides can be adjusted at the same time to adjust the center span of the vertical roller 17.

[0027] In order to ensure that the adjustment frames on both sides move linearly, a linear shaft 7 for limiting is provided at the front and rear ends of the adjustment frames, and the linear shaft 7 at the front and rear ends are symmetrically arranged. The linear shaft 7 is arranged in parallel with the horizontal pressure roller 2, and the two ends of the linear shaft 7 are respectively assembled on the two roller brackets 18 through the linear shaft seat 11; two sliders 5 are slidably arranged in the middle of the linear shaft 7, and the positions of the two sliders 5 correspond to the two adjustment frames one by one. The lower horizontal plate 4 of the adjustment frame extends to the front and rear sides respectively and is fixedly connected with the slider 5. When the adjustment screw 13 is rotated, the adjustment frame is restricted by the slider 5 and horizontally expands and contracts along the front and rear linear shafts 7 to ensure linear movement; because the left and right adjustment frames are both limited by the same linear shaft 7, the linear shaft 7 and the slider 5 have good synchronization in adjusting the span, and the profile 1 is always subjected to uniform and balanced force, so the roller cores of the left and right vertical rollers 17 are kept on the same straight line to ensure that the two sides of the cold-bent profile 1 are subjected to consistent force.

[0028] Preferably, threads are arranged at both ends of the linear shaft 7, and the two ends of the linear shaft 7 penetrate through the linear shaft seats 11 on both sides and are locked by linear shaft locking nuts 10. The middle part of the linear shaft 7 is a smooth shaft matched with the slider 5.

[0029] Preferably, the upper end surface of the slider 5 is a plane, and the bottom surface of the lower cross plate 4 is fixed with screws after being matched with the upper end surface of the slider 5. The surface contact increases the connection strength and avoids rotation during the translation process.

[0030] The linear shaft seat 11 is rigidly connected to the roller bracket 18 through the ear plates 20 on both sides. Specifically, the ear plates 20 are provided with elongated holes 21, and the end surface of the roller bracket 18 is provided with mounting holes corresponding to the elongated holes 21. The fastening screws penetrate the elongated holes 21 and the mounting holes and are locked, thereby fixing the linear shaft seat 11 on the side surface of the roller bracket 18. The arrangement of the elongated holes 21 can realize the adjustment of the height of the linear shaft seat 11, ensuring that the linear shaft seats 11 on the left and right sides have the same height and the linear shaft is level.

[0031] In order to facilitate the adjustment of the height of the linear shaft seat 11, a lifting assembly is also provided below the linear shaft seat 11. The lifting assembly includes a jacking screw 8 and a jacking screw fixing block 9. The jacking screw fixing block 9 is fixed to the roller bracket 18 by screws. The jacking screw 8 is installed on the jacking screw fixing block 9. The jacking screw 8 extends upward and its top is pressed against the bottom surface of the ear plate 20 below the linear shaft seat 11. When the vertical roller 17 needs to be adjusted, the height of the linear shaft seat 11 is adjusted by lifting the jacking screw 8, and then the vertical roller 17 is driven to rise and fall through the linear shaft 7 and the adjustment frame to achieve the adjustment of the height of the vertical roller 17.

[0032] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
