[0031] The following is combined with Figure 1 -to Figure 5 As shown, a multi-roll wide sheet metal common die blanking mold 100 according to an embodiment of the present invention is described.

[0032] like Figure 1 As shown, this disclosure proposes a multi-roll wide sheet metal common die blanking mold 100, including: a lower die base 20 and a speed change device 10, the speed change device 10 being disposed on both sides of the lower die base 20, wherein, (as shown) Figure 2 The transmission device 10 (as shown) includes: a gear-fixing mechanism 12 and a gear-shifting mechanism 11, wherein the gear-fixing mechanism 12 and the gear-shifting mechanism 11 are arranged opposite to each other (e.g., Figure 3 The gear-setting mechanism 12 (as shown) includes a drive component 121 and a gear-setting assembly 122. The drive component 121 and the gear-setting assembly 122 are movably connected (e.g., ...). Figure 3 The shifting mechanism 11 (as shown) includes: a shifting member 111 and a shifting assembly 112. The shifting member 111 is disposed on the shifting assembly 112. The shifting assembly 112 includes: a rotating shaft 1121 and a limiting member 1122. The limiting member 1122 is disposed on the outer periphery of the rotating shaft 1121. The gear setting assembly 122 includes: a gear position member 1221, which is disposed on the driving member 121. When the shifting member 111 adjusts the shifting assembly 112 to a predetermined gear, the driving member 121 drives the gear setting assembly 122 to bring the gear position member 1221 into contact with the limiting member 1122.

[0033] The lower die base 20 is fixed on the worktable, and the speed change device 10 is fixed on the lower die base 20. The lower die base 20 is a supporting component of the multi-roll wide plate common die blanking mold, and supports the speed change device 10.

[0034] The speed change device 10 is fixed on the upper die base. The speed change device 10 includes a fixing mechanism 12 and a shifting mechanism 11. Through the cooperation and adjustment of the fixing mechanism 12 and the shifting mechanism 11, uncoiling and blanking of sheet metal 30 with different roll widths can be achieved. The fixing mechanism 12 includes a driving component 121 and a fixing assembly 122. By driving the fixing assembly 122 through the driving component 121, accurate alignment of the stop component 1221 and the limit component 1122 can be ensured, thereby achieving precise blanking of the roll width. The shifting mechanism 11 includes: a shifting component 111 and a shifting assembly 112. The rotating shaft 1121 and the limiting component 1122 are two components of the shifting assembly 112. The shifting component 111 adjusts the shifting assembly 112 so that the limiting component 1122 contacts the shifting component 1221, thereby realizing the uncoiling and unwinding of sheet materials 30 with different roll widths. The rotating shaft 1121 can ensure the smooth operation of the limiting component 1122, and the limiting component 1122 can ensure precise alignment.

[0035] According to the embodiments of the present invention, the multi-roll width sheet metal common die blanking mold 100 can realize the uncoiling and blanking of sheet metal 30 with different roll widths through the cooperation and adjustment of the fixing mechanism 12 and the changing mechanism 11, thereby reducing the mold development cost and reducing the space occupation of the stamping production workshop; by adjusting the rotating shaft 1121 through the adjusting component 111, the rotating shaft 1121 drives the limiting component 1122 set on the rotating shaft 1121 to rotate by a predetermined angle, and the driving component 121 is activated. The driving component 121 drives the stopping component 1221 to slide forward to contact the limiting component 1122, thereby realizing the accurate blanking of the roll width and improving production efficiency and product quality.

[0036] According to one embodiment of the present invention, in order to achieve uncoiling and blanking of sheet metal 30 with different coil widths, the mold development cost is reduced and the space occupied in the stamping production workshop is reduced. Therefore, (e.g.) Figure 4 As shown, the limiting member 1122 includes at least four, and the four limiting members 1122 are evenly arranged 360° around the outer periphery of the rotation axis 1121, thereby realizing the uncoiling and unwinding of sheet materials 30 with different roll widths.

[0037] According to a specific embodiment of the present invention, four limiting members 1122 are provided to achieve precise cutting of different roll widths. For example, by adjusting the rotating shaft 1121 to the first position 11121 through the adjusting member 111, the rotating shaft 1121 drives the limiting member 1122 corresponding to the first position 11121 to rotate by a predetermined angle. The driving member 121 is then activated, causing the driving member 121 to drive the positioning member 1221 provided on the driving member 121 to move linearly until it contacts the limiting member 1122 corresponding to the first position 11121, thereby achieving precise cutting of the roll width sheet 30.

[0038] According to another specific embodiment of the present invention, four limiting members 1122 are provided to achieve precise cutting of sheet metal 30 with different roll widths. For example, based on the first gear 11121, the rotating shaft 1121 is adjusted to the second gear 11122 by the adjusting member 111, so that the rotating shaft 1121 drives the limiting member 1122 corresponding to the second gear 11122 to rotate by a predetermined angle, and the driving member 121 is activated, so that the driving member 121 drives the gear member 1221 provided on the driving member 121 to move linearly until it contacts the limiting member 1122 corresponding to the second gear 11122, thereby achieving precise cutting of sheet metal 30 with another roll width.

[0039] According to another specific embodiment of the present invention, four limiting members 1122 are provided to achieve precise cutting of sheet metal 30 with different roll widths. For example, based on the second position 11122, the rotating shaft 1121 is adjusted to the third position 11123 by adjusting the adjusting member 111, so that the rotating shaft 1121 drives the limiting member 1122 corresponding to the third position 11123 to rotate by a predetermined angle, and the driving member 121 is activated, so that the driving member 121 drives the positioning member 1221 provided on the driving member 121 to move linearly until it contacts the limiting member 1122 corresponding to the third position 11123, thereby achieving precise cutting of sheet metal 30 with different roll widths.

[0040] According to another specific embodiment of the present invention, four limiting members 1122 are provided to achieve precise cutting of sheet metal 30 with different roll widths. For example, based on the third position 11123, the rotating shaft 1121 is adjusted to the fourth position 11124 by the adjusting member 111, so that the rotating shaft 1121 drives the limiting member 1122 corresponding to the fourth position 11124 to rotate by a predetermined angle, and the driving member 121 is activated, so that the driving member 121 drives the positioning member 1221 provided on the driving member 121 to move linearly until it contacts the limiting member 1122 corresponding to the fourth position 11124, thereby achieving precise cutting of another roll width sheet metal 30.

[0041] Four limiting members 1122 and 360° are evenly arranged around the outer periphery of the rotating shaft 1121, enabling precise cutting of sheet metal 30 with different roll widths. The rotating shaft 1121 is adjusted to the first gear 11121, the second gear 11122, the third gear 11123, or the fourth gear 11124 by the adjusting member 111. At the same time, the rotation of the rotating shaft 1121 will drive the four limiting members 1122 on the rotating shaft 1121 to rotate at a predetermined angle, so that one of the four limiting members 1122 corresponds to one of the four gears. When the corresponding gear and the corresponding limiting member 1122 are engaged, the driving member 121 is activated, causing the driving member 121 to slide forward and drive the gear member 1221 on the driving member 121 to move to contact the limiting member 1122 corresponding to the gear, thereby achieving precise cutting of sheet metal 30 with different roll widths.

[0042] In some embodiments, in order to make the rotating shaft 1121 rotate more stably by a predetermined angle, the mutual switching between the various limiting members 1122 corresponding to each gear position is realized (e.g. Figure 3 The shifting assembly 112 (as shown) includes two bearing seats 1123, which are respectively sleeved on both ends of the outer periphery of the rotating shaft 1121. By adjusting the shifting component 111, the rotating shaft 1121 rotates axially along the inner wall of the through hole of the bearing seat 1123 by a predetermined angle, thereby ensuring the stability of the rotation. At the same time, the bearing seats 1123 serve as supporting components for the rotating shaft 1121, supporting the rotating shaft 1121 so that the height of the entire shifting mechanism and the fixed shifting mechanism 12 meets the predetermined standard. It also ensures that under the driving action of the driving component 121, the limiting component 1122 set on the rotating shaft 1121 contacts the shifting component 1221 set on the driving component 121, thereby achieving precise cutting of the roll width sheet 30. By setting four limiting components 1122 on the outer periphery of the rotating shaft 1121, the precise cutting of roll width sheet 30 can be further achieved.

[0043] In some embodiments, in order to rotate the rotating shaft 1121 to a predetermined angle, the limiting member 1122 is brought into contact with the stop member 1221 by rotating the predetermined angle, thereby achieving precise cutting of sheet metal 30 with different roll widths (e.g. Figure 3 (As shown) Therefore, the adjusting component 111 includes: a rotating disk 1111 and a scale disk 1112. The scale disk 1112 is disposed on the end face of the rotating shaft 1121. The rotating disk 1111 is disposed on the scale disk 1112 and is movably connected to the scale disk 1112. By rotating the rotating disk 1111, the rotating disk 1111 rotates circumferentially along the scale disk 1112 by a predetermined angle. At the same time, the rotating shaft 1121 rotates by a predetermined angle to achieve precise cutting of sheet metal 30 with different roll widths.

[0044] In some embodiments, in order to allow the four limiting members 1122 to contact the stop member 1221, (e.g.) Figure 5 As shown, the dial 1112 has four positions, and each position component 1221 corresponds to one position. For example, the first position 11121 corresponds to the first limiting component 11221, the second position 11122 corresponds to the second limiting component 11222, the third position 11123 corresponds to the third limiting component 11223, and the fourth position 11124 corresponds to the fourth limiting component 11224. By having the first limiting component 11221 contact with the position component 1221, the second limiting component 11222 contact with the position component 1221, the third limiting component 11223 contact with the position, and the fourth limiting component 11224 contact with the position, the precise cutting of sheet materials 30 with different roll widths can be achieved.

[0045] According to one embodiment of the present invention, in order to enable the driving member 121 to drive the gear positioning component 122 to move linearly, so that the gear positioning member 1221 contacts the limiting member 1122, therefore, (as...) Figure 3 As shown, the driving component 121 includes a cylinder 1212 and a telescopic shaft 1211. One end of the telescopic shaft 1211 is connected to the cylinder 1212, and a stop component 1221 is sleeved on the outer periphery of the telescopic shaft 1211 and away from the cylinder 1212. When the cylinder 1212 is activated, it drives the telescopic shaft 1211 to move linearly. At the same time, the stop component 1221 sleeved on the telescopic shaft 1211 moves telescopically under the drive of the cylinder 1212, thereby making the stop component 1221 contact the limiting component 1122, and further realizing the precise cutting of sheet metal 30 with different roll widths.

[0046] In some embodiments, in order for the telescopic shaft 1211 to perform telescopic movement, the limiting member 1122 can contact the stop member 1221 to achieve precise cutting of sheet metal 30 with different roll widths (e.g. Figure 3 (As shown) Therefore, the positioning assembly includes: a fixed base 1222 and a piston 1223. The piston 1223 is connected to the telescopic shaft 1211 via a stop component 1221, so as to drive the piston 1223 to perform telescopic movement. The piston 1223 is mounted on the fixed base 1222 to support the piston 1223 and achieve a sliding engagement. The fixed base 1222 has a sliding groove that slides with the piston 1223. The piston 1223 is inserted into the sliding groove and slides with it. Under the action of the telescopic shaft 1211, the sliding groove and the piston 1223 slide linearly, thereby realizing the contact between the limiting component 1122 and the stop component 1221, and further realizing the precise cutting of sheet metal 30 with different roll widths.

[0047] In some embodiments, after the limiting member 1122 contacts the stop member 1221, in order to better fix the precise unloading of the roll width sheet 30 (e.g. Figure 3 The positioning assembly (as shown) also includes a positioning roller 1224, which is mounted on the piston 1223 to fix the precisely rolled sheet 30.

[0048] In some embodiments, in order to achieve accurate cutting of the roll width sheet 30, the stop member 1221 is a stop plate, and the stop plate has a through hole that cooperates with the telescopic shaft 1211. By cooperating with the telescopic shaft 1211, a detachable connection is achieved.

[0049] In some embodiments, in order to achieve accurate cutting of the roll wide sheet 30, the limiting member 1122 is a limiting plate. The limiting plate contacts the stop plate, increasing the contact area, thereby ensuring accurate cutting of the roll wide sheet 30.

[0050] Combination Figures 1-5 This describes a specific embodiment of the multi-roll wide sheet metal common die blanking mold 100 of the present invention:

[0051] The uncoiling and blanking die includes a lower die base 20 and a speed change device 10. The speed change device 10 is mounted on the lower die base 20. The speed change device 10 includes a shifting mechanism 11 and a fixed-gear mechanism 12. The shifting mechanism 11 includes an adjusting component 111 and a shifting assembly 112. The shifting assembly 112 includes a rotating shaft 1121, four limiting components 1122, and a pair of bearing seats 1123. The four limiting components 1122 are limiting plates evenly fitted around the outer circumference of the rotating shaft 1121, evenly arranged in 360°. For example, the limiting plates have through holes that mate with the rotating shaft 1121. The two bearings are a pair, and the pair of bearings are spaced apart and mate with the two ends of the rotating shaft 1121. The rotating shaft 1121 can rotate along the inner hole of the bearing by a predetermined angle, thereby realizing the shifting of gears. The adjusting component 111 includes a rotating disk 1111 and a scale disk 1112. A rotating disk 1111 is mounted on a scale disk 1112, which is mounted on the rotating end face. The scale disk 1112 has four positions, which are arranged at intervals on the scale disk 1112, namely, the first position 11121, the second position 11122, the third position 11123, and the fourth position 11124.

[0052] The rotating disk 1111 rotates on the scale 1112, aligning the indicator on the rotating disk 1111 with the predetermined gear position on the scale 1112. This causes the rotating shaft 1121 to rotate around the inner wall of the bearing by a predetermined angle, and also drives the limiting plate set on the rotating shaft 1121 to rotate to the predetermined position, thereby realizing gear switching.

[0053] The positioning mechanism 12 includes a drive component 121 and a positioning assembly 122. The positioning assembly 122 includes a stop component 1221, a fixed base 1222, a piston 1223, and a positioning roller 1224. The drive component 121 includes a telescopic shaft 1211 and a cylinder 1212. One end of the telescopic shaft 1211 is connected to the cylinder 1212, and the telescopic shaft 1211 and the cylinder 1212 can extend and retract. The other end of the telescopic shaft 1211 is connected to the fixed base 1222 via the stop component 1221. The piston 1223 can slide back and forth on the fixed base 1222. The fixed base 1222 has a groove that slides with the piston 1223, and the piston 1223 is inserted into and slidably connected to the groove. The positioning roller 1224 is mounted on the fixed base and is used to adjust the roll width accordingly. Among them, the gear position component 1221 is a gear position plate, which is sleeved on the outer periphery of the telescopic shaft 1211. For example, the gear position plate has a through hole that mates with the telescopic shaft 1211.

[0054] After shifting the gear to the predetermined position, the drive unit 121 drives the piston 1223 to slide forward along the groove of the fixed seat 1222 to the predetermined position (e.g., Figure 3 (As shown in the front-back direction), the stop plate 1221 (stop plate) on the drive component 121 contacts the limiting plate 1122 (limiting plate), thereby achieving precise blanking of the roll width, and further achieving precise blanking of sheet metal 30 with different roll widths. After the stop plate 1221 (stop plate) contacts the limiting plate 1122 (limiting plate), it is fixed by the positioning roller 1224, thereby achieving precise positioning of the roll width. Among them, the four limiting plates 1122 correspond to four stops, each stop corresponds to a roll width, and the roll widths corresponding to the four stops are different, so the roll width sheet metal 30 needs to be selected according to the requirements. The width of the uncoiling and blanking knife 40 on the lower die base 20 is set according to the maximum roll width.

[0055] According to an embodiment of the present invention, the multi-roll wide sheet metal common die blanking mold 100 achieves precise blanking of multi-roll wide sheet metal 30 by setting the speed change device 10 on the lower die base 20; through the mutual cooperation and adjustment of the fixing mechanism 12 and the shifting mechanism 11, the unwinding and blanking of sheet metal 30 of different roll widths can be realized, reducing the mold development cost and reducing the space occupation of the stamping production workshop; by adjusting the rotating shaft 1121 through the adjusting component 111, the rotating shaft 1121 drives the limiting component 1122 set on the rotating shaft 1121 to rotate to a predetermined position, and the driving component 121 is activated. The driving component 121 pushes the piston 1223 to slide forward along the slide groove of the fixed base 1222, so that the stop component 1221 contacts the limiting component 1122, thereby achieving precise blanking of the sheet metal 30 of different roll widths, improving production efficiency and product quality; through the corresponding cooperation of the four limiting components 1122 and the four stops, the precise blanking of sheet metal 30 of different roll widths can be realized.

[0056] It should be noted that the four limiting components 1122 are the first limiting component 11221, the second limiting component 11222, the third limiting component 11223, and the fourth limiting component 11224. The four gear positions are the first gear position 11121, the second gear position 11122, the third gear position 11123, and the fourth gear position 11124. The first limiting member 11221 is aligned with the first gear position 11121, and the first gear position 11121 controls the first limiting member 11221; the second limiting member 11222 is aligned with the second gear position 11122, and the second gear position 11122 controls the second limiting member 11222; the third limiting member 11223 is aligned with the third gear position 11123, and the third gear position 11123 controls the third limiting member 11223; the fourth limiting member 11224 is aligned with the fourth gear position 11124, and the fourth gear position 11124 controls the fourth limiting member 11224.

[0057] The multi-roll wide sheet metal common die blanking mold 100 and other configurations and operations described in this invention are known to those skilled in the art and will not be described in detail here.
