[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0028] like Figure 1 As shown, a panel bending fixture of this utility model includes a pressure plate 1, a base plate 3, a lifting plate 4, a spring 7, and a fixing block 8; the pressure plate 1 is located above the base plate 3, as shown. Figure 2 As shown, the bottom of the pressure plate 1 is provided with a pressure block 2, the bottom of the pressure block 2 is provided with a first clearance groove 21, and both sides of the pressure block 2 are provided with guide shafts 11.
[0029] like Figure 3-4 As shown, the lifting plate 4 is connected to the top of the base plate 3 by a spring 7, and the two sides of the lifting plate 4 are provided with perforated guide posts 31 that are compatible with the guide shaft 11.
[0030] The lifting plate 4 is composed of a material placement part 41 and a connecting part 42. The material placement part 41 is provided with a material placement plate 5 and several positioning parts 6. The several positioning parts 6 are arranged one by one on the outer wall of the material placement plate 5. The material placement plate 5 is provided with a positioning plate 51. The connecting part 42 is provided with a connecting groove 421. The fixing block 8 is located in the connecting groove 421 and fixed to the top of the base plate 3.
[0031] like Figure 5 As shown, the bottom plate 3 is connected to the top of the pressing limit block 32; the bottom plate 3 is provided with a limit opening 35, which is convex in shape; the bottom of the lifting plate 4 is connected to a reset positioning rod 33; the end of the reset positioning pin 33 is provided with a locking block 331, which is locked in the limit opening 35.
[0032] This utility model discloses a panel bending fixture. Panel 9 is laid flat on a placement plate 5, and the groove on panel 9 is fitted onto a positioning plate 51 to position panel 9 and prevent it from sliding. Then, using an existing cylinder or other transmission component, pressure plate 1 is lowered. Guide shaft 11 aligns with perforated guide post 31, and pressure plate 1 descends along perforated guide post 31. The first clearance groove 21 of pressure block 2 engages with positioning plate 51, and pressing down lifting plate 4. Figure 7 As shown, the panel 9 on the lifting plate 4 descends, while the panel 9 lying flat on the fixing block 8 folds up, achieving bending of the panel 9. Subsequently, the spring 7 plays a resetting role, resetting the lifting plate 4 that has been released.
[0033] Auxiliary pressure rods 12 are provided on both sides of the briquette 2. When the briquette 2 presses down the lifting plate 4, the auxiliary pressure rods 12 on both sides of the briquette 2 play an auxiliary pressing role, ensuring that the lifting plate 4 receives a uniform downward pressure, further improving the smoothness of the descent of the lifting plate 4, and preventing one end of the lifting plate 4 from tilting, which may affect the bending effect of the panel.
[0034] A second relief groove 22 is provided on the side wall of the briquette 2 close to the fixed block 8. During the panel bending process, when the panel on the fixed block 8 is folded up, the edge of the panel is likely to rub against the side wall of the briquette 2. Since the panel is not cooled at this time, the edge of the panel rubbing against the briquette 2 is likely to deform, affecting the appearance of the panel. The second relief groove 22 can provide a relief space, reducing the risk of friction or collision between the folded part of the panel and the briquette 2.
[0035] When the panel is laid flat on the material placing plate 5, the edge of the panel is attached to the side walls of each positioning member 6. The positioning member 6 further positions the panel, preventing the part of the panel on the material placing plate 5 from shifting when the lifting plate 4 descends, which may affect the bending position of the panel. The positioning member 6 is provided with an adjustment groove 61. The first fastener 62 detachably connects the positioning member 6 to the material placing part 41 through the adjustment groove 61. According to the size of the panel, the position of each positioning member 6 can be adjusted by selecting the installation position of the adjustment groove 61 to meet the positioning requirements of panels of various sizes.
[0036] The downward pressure limiting block 32 restricts the downward position of the lifting plate 4. When the lifting plate 4 descends to the limit distance, the bottom of the lifting plate 4 will collide with the downward pressure limiting block 32. The downward pressure limiting block 32 prevents the lifting plate 4 from continuing to descend, avoiding the collision between the lifting plate 4 and the bottom plate 3, which may affect the service life of the tooling. As Figure 5 shown, the downward pressure limiting block 32 is connected to the top of the bottom plate 3 through the second fastener 321. The second fastener 321 can be a screw. The downward pressure limiting block 32 can be disassembled and assembled by screwing, which is convenient for replacing the worn downward pressure limiting block 32 and can also adjust the height of the downward pressure limiting block 32 according to the use requirements to adjust the limiting height of the downward pressure limiting block 32 for the descent of the lifting plate 4.
[0037] Since the upward reset of the lifting plate 4 is realized by the spring 7, the latch 331 of the reset positioning pin 33 will be stuck in the "convex" - shaped limiting port 35, restricting the reset height of the lifting plate 4 to make up for the insufficient reset accuracy of the spring 7 for the lifting plate 4. The reset positioning pin 33 is preferably thread - connected to the lifting plate 4. By screwing the reset positioning pin 33, the protruding distance of the reset positioning pin 33 on the lifting plate 4 can be quickly adjusted, which is convenient for machine adjustment and can flexibly adjust the limiting height of the reset positioning pin 33 for the upward movement of the lifting plate 4.
[0038] As Figure 6As shown, the top of the base plate 3 is provided with a buffer column 34, and the lifting plate 4 is provided with a pressure groove 45 adapted to the buffer column 34. When the lifting plate 4 descends, the pressure groove 45 contacts the buffer column 34, and the buffer column 34 provides shock absorption for the lifting plate 4, further improving the stability of the descent of the lifting plate 4, reducing the shaking of the lifting plate 4, and avoiding affecting the bending position of the panel.
[0039] The connection between the material placement part 41 and the connecting part 42 is rounded at the corner 45, forming a smooth transition at the intersection of the material placement part 41 and the connecting part 42. During the bending process of the panel, part of the panel descends and part of the panel slowly folds up along the rounded corner 45. The rounded corner 45 can reduce stress concentration, making the panel fold up more smoothly and steadily.
[0040] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
