Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a width adjustment mechanism for a longitudinal cutting sub-die of an air-conditioning fin. Background Technique

[0002] Air-conditioning fins are the main heat exchange components in household air conditioners, central air conditioners, vehicle air conditioners, and fan coil units, and have the functions of increasing the heat exchange surface area and improving the heat exchange efficiency. Currently, the general air-conditioning fins are made by stamping with an air-conditioning fin die.

[0003] After retrieval, a Chinese patent with the publication number of CN102294515B discloses a width adjustment mechanism for a longitudinal cutting sub-die of an air-conditioning fin, which includes multiple columns of longitudinally cutting upper knives and longitudinally cutting lower knives corresponding in position. The longitudinally cutting upper knives are installed at the bottom of the upper knife fixing blocks, and multiple upper knife fixing blocks are installed on an upper template. Both sides of the top of the upper knife fixing block are each connected with a push rod. There is a spring in the middle of the push rod, and an adjustment pressing plate covers the top of the push rod. The adjustment pressing plate covers the entire upper template and is fixed on the upper template by screws. Regularly arranged holes are processed at the bottom of the adjustment pressing plate.

[0004] This mechanism replaces the single-column adjusting adjustment pads with a whole adjustment pressing plate. When adjusting the column width, just loosen the screws, move the adjustment pressing plate to the required column number, and then tighten the screws. When there is a hole at the position corresponding to the push rod connected to the upper knife fixing block, the upper and lower knives do not cut, otherwise they cut, improving the efficiency of assembly and debugging.

[0005] However, this mechanism still has the following problems. The mechanism loosens the screws, then moves the adjustment pressing plate to the specified position, and then tightens the screws to fix the adjustment pressing plate. In the actual use process, the process of loosening and tightening the screws needs to be repeated many times, the operation is cumbersome, and continuous debugging is required, consuming a lot of time costs and making it difficult to effectively improve the width adjustment efficiency.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment: As Figure 1As shown in the figure, a width adjustment mechanism for a longitudinal cutting sub - mold of an air - conditioner fin includes a mold frame 1. The mold frame 1 is made of composite metal materials to enhance the overall structural strength of the structure. A hydraulic driving mechanism 2 is arranged above the mold frame 1, and the output end of the hydraulic driving mechanism 2 is fixedly connected to the top end of the mold frame 1. The hydraulic driving mechanism 2 plays a role in driving the mold frame 1 to move. It also includes an adjustment component and a longitudinal cutting component arranged inside the mold frame 1.

[0026] As Figure 3 shown Figure 4 in a certain embodiment, in order to improve the efficiency of the mechanism to adjust the width, the adjustment component includes an extrusion plate 27 slidably connected to the inner wall of the mold frame 1. One side of the top of the extrusion plate 27 is fixedly connected to a threaded sleeve 24. One side of the inner top of the mold frame 1 is rotatably connected to a threaded column 22 that meshes with the threaded sleeve 24. Through the mutual cooperation between the threaded column 22 and the threaded sleeve 24, the extrusion plate 27 is driven to move along the inner wall of the mold frame 1. A plurality of limiting rods 8 are fixedly connected to both sides of the inner wall of the mold frame 1. One end of the outer peripheral wall of the plurality of limiting rods 8 is jointly fixedly connected to a fixed support plate 9. A main connecting plate 10 is slidably connected to the outer peripheral wall of the plurality of limiting rods 8 near the fixed support plate 9. The other ends of the plurality of limiting rods 8 are jointly slidably connected to a set of driven connecting plates 11. The bottom of the extrusion plate 27 is fixedly connected to multiple pairs of guide rails 12. Multiple fixing seats two 14 are fixedly connected to the bottom of the extrusion plate 27 near the fixed support plate 9. Multiple fixing seats one 13 are fixedly connected to one side of the top of the main connecting plate 10. Multiple telescopic plates 17 are fixedly connected to one side of the top of the main connecting plate 10 and one side of the top of the driven connecting plate 11. Multiple fixing seats three 15 are fixedly connected to the other side of the top of each driven connecting plate 11. A set of fixing seats four 16 are slidably connected to the inner wall of each guide rail 12, and the bottom ends of the fixing seats four 16 are fixedly connected to the extending ends of the telescopic plates 17. A pair of connecting rods 18 are rotatably connected between one end of each fixing seat one 13 and the adjacent one end of the fixing seat two 14, and between one end of the fixing seat three 15 and the adjacent one end of the fixing seat four 16 through a rotating shaft. By driving the fixing seat two 14 to move downward through the extrusion plate 27, and then through the mutual cooperation between the fixing seat two 14, the fixing seat one 13 and the connecting rod 18, the main connecting plate 10 slides away from the fixed support plate 9 along the direction of the limiting rod 8. At the same time, the main connecting plate 10 drives the telescopic plate 17 and the fixing seat four 16 to move synchronously. At the same time, the extrusion plate 27 squeezes the telescopic plate 17, driving the fixing seat four 16 to move downward. Then, through the mutual cooperation between the fixing seat three 15, the fixing seat four 16 and the connecting rod 18, the driven connecting plate 11 slides away from the main connecting plate 10 along the direction of the limiting rod 8, and the sliding distance of each driven connecting plate 11 is twice the sliding distance of the main connecting plate 10.

[0027] As Figure 3As shown, in a certain embodiment, in order to improve the stability of the width adjustment of the mechanism, a pair of fixing brackets 19 are fixedly connected to the inner top of the mold frame 1 near the threaded column 22. One end of the pair of fixing brackets 19 is rotatably connected to a worm 20. One end of the threaded column 22 is fixedly connected to a worm gear 23 that meshes with the worm 20, and the lead angle between the worm gear 23 and the worm 20 is less than the friction angle. Through the mutual cooperation between the worm gear 23 and the worm 20, the threaded column 22 is driven to rotate. At the same time, due to the self-locking effect between the worm gear 23 and the worm 20, it is avoided that the threaded column 22 rotates under the action of external forces during the longitudinal cutting process after the adjustment is completed. A bidirectional motor 21 is fixedly connected to the inner top of the mold frame 1 near the worm 20, and the output shaft of the bidirectional motor 21 is fixedly connected to one end of the worm 20. A plurality of guide rods 25 are fixedly connected to the top of the pressing plate 27 away from the threaded sleeve 24. The outer peripheral wall of each guide rod 25 is slidably connected to a guide sleeve 26, and the top end of the guide sleeve 26 is fixedly connected to the inner bottom of the mold frame 1. Through the mutual cooperation between the guide rod 25 and the guide sleeve 26, the stability of the movement of the pressing plate 27 is improved.

[0028] As Figure 2 with Figure 3 As shown, in a certain embodiment, in order to further improve the stability of the width adjustment of the mechanism, the longitudinal cutting assembly includes a pair of chutes 3 opened at the bottom end of the inner wall of the mold frame 1. The bottom end of the fixed support plate 9 is fixedly connected to a fixed upper template 4, and one end of the fixed upper template 4 is fixedly connected to the inner wall of the chute 3. The bottom end of the active connecting plate 10 is fixedly connected to an active upper template 5, where the active connecting plate 10 plays a role in driving the active upper template 5 to move. The bottom end of each driven connecting plate 11 is fixedly connected to a driven upper template 6, and the driven connecting plate 11 plays a role in driving the driven upper template 6 to move. One end of the driven upper template 6 and one end of the active upper template 5 are both slidably connected to the inner wall of the chute 3. Through the setting of the chute 3, the stability of the width adjustment of the longitudinal cutting upper knives 7 of the mechanism is further improved. The bottom ends of the fixed upper template 4, the active upper template 5, and the driven upper template 6 are all fixedly connected to longitudinal cutting upper knives 7.

[0029] Working principle: When in use, first start the bidirectional motor 21. Drive the worm 20 to rotate through the bidirectional motor 21. Then, drive the threaded column 22 to rotate through the mutual cooperation between the worm 20 and the worm gear 23. Then, drive the pressing plate 27 to slide downward along the inner wall of the die frame 1 through the mutual cooperation between the threaded column 22 and the threaded sleeve 24. Then, drive the second fixed seat 14 to move downward through the pressing plate 27. Then, drive the active connecting plate 10 to slide away from the fixed support plate 9 along the direction of the limiting rod 8 through the mutual cooperation between the second fixed seat 14, the first fixed seat 13 and the connecting rod 18. Then, drive the active upper template 5 to slide away from the fixed upper template 4 along the chute 3 through the active connecting plate 10. At the same time, the pressing plate 27 presses the telescopic plate 17, so that the telescopic plate 17 drives the fourth fixed seat 16 to move downward. At the same time, the active connecting plate 10 drives the telescopic plate 17 and the fourth fixed seat 16 to slide away from the fixed support plate 9 along the direction of the guide rail 12. Then, drive the driven connecting plate 11 to slide away from the active connecting plate 10 along the direction of the limiting rod 8 through the mutual cooperation between the fourth fixed seat 16, the third fixed seat 15 and the connecting rod 18. And the sliding distance of each driven connecting plate 11 is twice the sliding distance of the active connecting plate 10, so that the distances between the active connecting plate 10 and the fixed support plate 9, between the active connecting plate 10 and the driven connecting plate 11, and between the driven connecting plate 11 and the adjacent driven connecting plate 11 increase synchronously, effectively improving the width adjustment efficiency of the longitudinal cutting sub-die. After the adjustment is completed, through the self-locking effect between the worm gear 23 and the worm 20, avoid the position deviation of the longitudinal cutting upper knife 7 caused by external force during the longitudinal cutting process, and improve the stability of the mechanism use.
