[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0031] Please see Figures 1-6 As shown, this utility model is a continuous feeding fixture for metal rolling, including a lower support 2 and an upper support 3 fixedly installed at the feed end of the rolling mill 1 by bolts. Both the lower support 2 and the upper support 3 have pre-drilled mounting holes for connection with the rolling mill 1. Figure 3 As shown, in order to facilitate the entry of the sheet metal, the lower support seat 2 extends at the front end of the calender 1 for a longer length than the upper support seat 3, which facilitates the placement of the sheet metal on the lower support seat 2. The lower support seat 2 is located below the upper support seat 3. Several horizontally arranged lower guide rollers 21 are rotatably arranged on the lower support seat 2. The upper support seat 3 is provided with an adjustable height adjustment seat 4. Several horizontally arranged upper guide rollers 5 are rotatably arranged on the adjustment seat 4 and are distributed parallel to the lower guide rollers 21.
[0032] An inclined groove 31 is provided on the upper support 3. A slide 41 is fixed on the side of the adjusting seat 4 and slides in cooperation with the groove 31. The inclined sliding of the slide 41 in the groove 31 causes the upper guide roller 5 to adjust its height. The sliding distance of the slide 41 in the groove 31 is greater than the height adjustment distance of the upper guide roller 5. An internal threaded hole 42 is provided through the slide 41. An adjusting screw 6 is rotatably installed in the groove 31 and threaded in the internal threaded hole 42. The internal threaded hole 42 drives the slide 41 to slide in the groove 31 through the spiral of the internal threaded hole 42.
[0033] Specifically, the slide groove 31 and slide seat 41 are provided with two symmetrical sets, and the adjusting screws 6 are also provided with two symmetrical ones. The upper ends of the two adjusting screws 6 are fixed with first bevel gears 61. The front end of the upper support seat 3 is fixed with multiple extension blocks 33. The extension blocks 33 are provided with rotating connecting rods 7. Two second bevel gears 71 are fixed on the connecting rods 7 respectively and mesh with two first bevel gears 61. In this embodiment, the two adjusting screws 6 are linked synchronously by the connecting rods 7, which can ensure the adjustment accuracy of the upper guide roller 5 and keep the upper guide roller 5 in a horizontal state for adjustment.
[0034] Specifically, a threaded sleeve 331 is formed on one end of the extension block 33, and a clamping screw 8 is threadedly engaged in the threaded sleeve 331. The threaded sleeve 331 is connected to the shaft hole of the connecting rod 7 of the extension block 33. The clamping screw 8 is clamped to the connecting rod 7 by the screw of the threaded sleeve 331. In this embodiment, the connecting rod 7 is clamped radially by the threaded structure to limit the circumferential movement of the connecting rod 7 and prevent the upper guide roller 5 from being displaced by the vibration of the calender 1 during use. In actual use, in order to further increase the locking strength of the connecting rod 7, a clamping screw 8 can be set on each extension block 33 to apply pressure to the connecting rod 7.
[0035] Furthermore, a handwheel 72 is fixed at one end of the connecting rod 7 near the extension block 33 with a threaded sleeve 331. The handwheel 72 has a rotating handle. By rotating the handwheel 72 with the handle, the two second bevel gears 71 on the connecting rod 7 are simultaneously engaged with the two first bevel gears 61, thereby achieving synchronous displacement of the two ends of the adjusting seat 4 and the upper guide roller 5, ensuring adjustment accuracy.
[0036] Furthermore, a screw wheel 81 is fixed at the end of the clamping screw 8 away from the connecting rod 7. In addition, the end of the clamping screw 8 can also be provided with an inner / outer hexagonal structure to cooperate with a wrench. By increasing the torque through the wrench, the clamping force between the clamping screw 8 and the connecting rod 7 can be increased, which can further ensure the stability after adjustment.
[0037] Specifically, a scale 32 is provided on the side of the upper support 3 along the path of the slide groove 31, and a pointer 411 is provided on the outside of the slide 41 corresponding to the scale 32. The height adjustment distance of the upper guide roller 5 is calculated by matching the dimensions of the scale 32 and the pointer 411. For example, the adjustable height of the upper guide roller 5 is 2CM, and the movable distance of the slide 41 on the slide groove 31 is 4CM. When the slide 41 moves 2CM, it means that the height of the upper guide roller 5 has been displaced by 1CM.
[0038] Understandably, this utility model features corresponding rolling lower and upper guide rollers in the feeding section of the calender, effectively preventing the sheet material from jumping during feeding, ensuring the flatness of the calendered surface, and not affecting the conveying process. At the same time, the upper guide roller is mounted on an adjusting seat with an adjustable structure, allowing its height to be flexibly adjusted according to the sheet material thickness. Furthermore, through the cooperative design of the inclined slide groove and the slide seat, the effective distance of the adjusting screw is increased without changing the adjustment stroke, thereby improving the adjustment accuracy.
[0039] A specific application of this embodiment is as follows: both the lower support 2 and the upper support 3 are fixed to the feed end of the calender 1 by bolts, and the top surface of the upper and lower guide rollers 21 of the lower support 2 is flush with the top of the lower pressure roller of the calender 1, such as... Figure 1-3 This is the installation state of the feeding fixture on the calender 1, used for calendering automotive metal coils and sheets;
[0040] The coiling and uncoiling mechanism drives the sheet metal through the feeding fixture and calender 1 for calendering. The coiling mechanism is located at one end of the feeding fixture of the calender 1, and the uncoiling mechanism is located on the side of the calender 1 near the lower support 2, forming a closed loop of calendering and continuous feeding.
[0041] Position adjustment of the upper guide roller 5: By rotating the connecting rod 7 through the handwheel 72, the connecting rod 7 simultaneously drives the two second bevel gears 71 to mesh with the first bevel gears 61 on the two adjusting screws 6. The two adjusting screws 6 rotate synchronously and generate a spiral with the internal threaded hole 42. The axial movement force of the spiral drives the slide 41 to slide in the inclined slide groove 31. The slide 41 drives the adjusting seat 4 and the upper guide roller 5 to move. The vertical movement force generated by the inclined sliding changes the distance between the upper guide roller 5 and the lower guide roller 21, thereby adapting to the stable feeding of plates of different thicknesses. After the adjustment is completed, the clamping screw 8 is tightened by the screw wheel 81 to press the front end of the clamping screw 8 against the connecting rod 7, thereby strengthening the locking effect after adjustment.
