Description

Technical Field

[0001] This utility model relates to the field of hot rolling technology of magnesium alloy thin plates, and in particular to an online plate shape adjustment device for hot rolling of magnesium alloy thin plates. Background Technology

[0002] Warm rolling of magnesium alloy sheets refers to a process in which magnesium alloy billets are heated to near their recrystallization temperature and then subjected to multi-pass continuous deformation processing using a rolling mill. Compared to cold rolling, warm rolling effectively reduces the risk of cracking in magnesium alloys due to their poor room temperature plasticity. It also reduces rolling force, improves the uniformity of the sheet's microstructure and mechanical properties, and allows it to maintain high strength while possessing better ductility and flatness. This process is widely used in fields such as automotive, aerospace, and electronics, where lightweighting and high-quality forming are critical requirements.

[0003] In existing technologies, it is difficult to cut the board according to the needs. Usually, it can only be done manually or by cutting to a fixed length. This is not only cumbersome and inefficient, but also difficult to ensure the accuracy of the cutting position, which can easily cause the board size deviation or edge burrs, thus affecting the quality of the finished product and the connection of subsequent processing.

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.

[0027] Example 1:

[0028] Reference Figure 1 and Figure 2An embodiment of this utility model provides: an online shape adjustment device for hot rolling of magnesium alloy thin plates, including a fixed plate 1, an mounting frame 3 is provided on the left side of the upper surface of the fixed plate 1, and an mounting frame 4 is provided inside the mounting frame 3. Pressure rollers 5 are provided on both the left and right sides inside the mounting frame 4. A positioning frame 10 is provided on the upper side of the mounting frame 3, and a path rod 11 is provided inside the positioning frame 10. Two sets of moving blocks 12 are sleeved on the outside of the path rod 11. Two sets of support rods 13 are connected between the two sets of moving blocks 12 and the mounting frame 4. Two sets of mounting plates 15 are provided on the right side of the upper surface of the fixed plate 1, and a reciprocating assembly 16 is provided between the two sets of mounting plates 15. A cutter 17 is provided at the lower end of the reciprocating assembly 16.

[0029] Specifically, by adjusting the position of the two sets of moving blocks 12 outside the path rod 11, the position of the mounting frame 4 is adjusted by the support rod 13 to ensure that the thickness of the pressed plate can be adjusted. By opening the set reciprocating component 16, the reciprocating component 16 drives the cutter 17 to move back and forth, thereby cutting the pressed plate into a suitable size.

[0030] Reference Figure 5 The reciprocating assembly 16 includes two sets of rotating motors 161. The two sets of rotating motors 161 are fixedly installed on the upper ends of the two sets of mounting plates 15 on opposite sides. The ends of the two sets of rotating motors 161 that are close to each other are connected to rotating plates 162. The lower ends of the two sets of rotating plates 162 are hinged to connecting plates 163. The lower ends of the two sets of connecting plates 163 are rotatably mounted with movable rods 164. The middle position of the side of the two sets of mounting plates 15 that are close to each other is provided with positioning plates 165. The two sets of movable rods 164 are respectively movably inserted between the two sets of positioning plates 165. The lower ends of the two sets of movable rods 164 are connected to the front and rear ends of the cutter 17.

[0031] Specifically, by turning on two sets of rotating motors 161, two sets of rotating plates 162 are driven to rotate. Then, the position of the connecting plate 163 is adjusted by the two sets of rotating plates 162, thereby driving the movable rod 164 to move through the connecting plate 163. The position of the movable rod 164 is restricted by the positioning plate 165, thereby driving the cutting blade 17 to move back and forth to ensure that the plate is cut to the appropriate size.

[0032] Reference Figure 1 Stabilizing bases 2 are installed at the four corners of the lower surface of the fixing plate 1;

[0033] Specifically, the stabilizer 2 can distribute and bear the vibration and impact forces from the device during operation, preventing the device from shaking or displacing due to uneven force.

[0034] Reference Figure 3Scraper rods 6 are installed on both the upper left and right sides of the mounting frame 4, and the two sets of scraper rods 6 are connected to the pressure roller 5. A drive motor 7 is installed on the left side of the upper surface of the mounting frame 4, and a first gear 8 is connected to the front end of the drive motor 7. A second gear 9 is provided on the front side of the left pressure roller 5, and the first gear 8 and the second gear 9 mesh.

[0035] Specifically, when the drive motor 7 is turned on, the left pressure roller 5 can be rotated through the cooperation of the first gear 8 and the second gear 9. Thus, the pressure roller 5 heat-rolls the sheet while conveying it to the underside of the cutter 17. The scraper 6 can remove foreign objects and impurities attached to the roller surface in time during the operation of the pressure roller 5, avoiding the accumulation of foreign objects that cause uneven force on the pressure roller 5, thereby ensuring the adhesion effect between the pressure roller 5 and the surface of the sheet, and improving the flatness and surface quality of the rolled sheet.

[0036] Reference Figure 4 The path rod 11 has a corresponding threaded structure at both ends, and the two sets of moving blocks 12 are respectively provided with matching threaded holes. A rotary motor 14 is installed at the front end of the path rod 11, and the two sets of support rods 13 are respectively hinged between the two sets of moving blocks 12 and the mounting frame 4.

[0037] Specifically, by turning on the rotary motor 14, the path rod 11 is driven to rotate. Then, through the relative threaded structure, the two sets of moving blocks 12 move relative to each other outside the path rod 11. Then, the angle of the support rod 13 is adjusted, and the position of the mounting frame 4 is adjusted by the support rod 13, thereby adjusting the distance between the pressure roller 5 and the fixed plate 1. The thickness of the plate heat-rolled material can be adjusted as needed.

[0038] Example 2:

[0039] Reference Figure 6 The reciprocating assembly 16 includes a rotary motor 161, which is mounted on the front surface of the front mounting plate 15. A rotating rod 166 is connected to the rear side of the rotary motor 161, and a third gear 167 is respectively sleeved at the front and rear ends of the rotating rod 166. A movable ring 168 is movably mounted on the side of the two mounting plates 15 that are close to each other, and the lower ends of the two movable rings 168 are connected to the cutter 17. The two third gears 167 are set as half gears, and matching tooth grooves are respectively provided on the left and right sides inside the movable rings 168.

[0040] Specifically, by turning on the rotating motor 161, the rotating rod 166 is driven to rotate, and then the rotating rod 166 drives the third gear 167 to rotate. Then, the outer teeth of the third gear 167 engage with the grooves in the moving ring 168, so that the moving ring 168 can move back and forth up and down on the surface of the mounting plate 15, thereby driving the cutter 17 to move back and forth up and down.

[0041] Working principle: Turn on the rotary motor 14, adjust the position of the moving block 12 through the path rod 11, then adjust the position of the mounting frame 4 through the support rod 13 to adjust the thickness of the formed plate, turn on the drive motor 7 to make the first gear 8 and the second gear 9 drive the pressure roller 5 to rotate, extruding and conveying the plate at the same time, then turn on the reciprocating assembly 16 to drive the cutter 17 to move up and down back and forth, thereby cutting the plate into the appropriate size.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
