Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1-4 As shown, the first embodiment of this utility model provides a stepless adjustable roll width guide device for progressive die based on the prior art, comprising: a support assembly 10 connected to a progressive stamping die 80; two support seats spaced apart and connected to the support assembly 10 respectively; a coupling 40 disposed between the two support seats and connected to the support assembly 10; a first transmission screw 50 movably connected to one of the two support seats, with its first end connected to the first actuating end of the coupling 40; and a second transmission screw 60 movably connected to the other of the two support seats, with its first end connected to the coupling 40. The second actuator end of 40 is connected, and the external thread of the second transmission screw 60 is set in the opposite direction to the external thread of the first transmission screw 50; the first guide frame 20 is disposed between one of the two support seats and the coupling 40, the first guide frame 20 is movably connected to the first transmission screw 50, and the first guide frame 20 is movably connected to the support assembly 10; the second guide frame 70 is disposed between the other of the two support seats and the coupling 40, the second guide frame 70 is movably connected to the second transmission screw 60, and the second guide frame 70 is movably connected to the support assembly 10; wherein, rotating one of the second transmission screw 60 and the first transmission screw 50 in either forward or reverse direction allows the first guide frame 20 and the second guide frame 70 to move relatively closer or further apart.

[0023] In this embodiment, the support assembly 10 is connected to the progressive stamping die 80. The first transmission screw 50 and the second transmission screw 60 are supported by two support seats. The coupling 40 is used to achieve linkage. With the help of the opposite screw thread design, rotating one of the transmission screws in the forward or reverse direction can drive the first guide frame 20 and the second guide frame 70 to move closer or further apart. It can adapt to the uncoiling of rolls of various widths, meet the common needs of the same die for different roll widths, reduce the number of dies to develop and reduce costs. Moreover, the overall structure is simple, the standard parts are easy to install, and the positioning is accurate, which can effectively meet the roll positioning requirements of the uncoiling process.

[0024] In an exemplary embodiment, the progressive die stepless adjustment roll width guide device further includes: a rotary handle 30, the output shaft of which is connected to the second end of the second transmission screw 60, and the rotary handle 30 is spaced apart from the support assembly 10, the coupling 40, the first transmission screw 50, the first guide frame 20, and the second guide frame 70.

[0025] In this embodiment, the progressive die stepless adjustment roll width guide device, after adding a rotating handle 30, has its output shaft connected to the second end of the second transmission screw 60 and spaced apart from the support assembly 10, coupling 40, first transmission screw 50, first guide frame 20, and second guide frame 70. This not only provides operators with a convenient manual adjustment component, allowing them to directly drive the second transmission screw 60 to rotate via the rotating handle 30, thereby coordinating with the coupling 40 to drive the first transmission screw 50 to move synchronously, achieving relative movement of the first guide frame 20 and the second guide frame 70, making the roll width adjustment operation more intuitive and effortless, but also avoids interference with other components due to the spaced arrangement, ensuring the smoothness of the adjustment process and the stability of the structural operation, further improving the practicality and ease of operation of the device.

[0026] Further, at least one of the first guide frame 20 and the second guide frame 70 includes: a guide base 903, which is movably connected to the first transmission screw 50 or the second transmission screw 60, and one end of the guide base 903 is movably connected to the support assembly 10; a guide support 902, which is connected to the guide base 903 and is spaced apart from the first transmission screw 50, the second transmission screw 60 and the support assembly 10; a guide assembly 904, which is connected to the guide support 902 and is spaced apart from the first transmission screw 50, the second transmission screw 60 and the support assembly 10, and engages with the edge of the coil 90; and a guide roller 901, which is movably connected to the guide support 902 and is spaced apart from the first transmission screw 50, the second transmission screw 60, the guide assembly 904 and the support assembly 10, and engages with the edge of the coil 90.

[0027] In this embodiment, at least one of the first guide frame 20 and the second guide frame 70 is movably connected to the first transmission screw 50 or the second transmission screw 60 and the support assembly 10 via the guide base 903. It cooperates with the guide support seat 902 to connect the guide assembly 904 and the guide roller 901. The guide support seat 902, the guide assembly 904, and the guide roller 901 are all spaced apart from the first transmission screw 50, the second transmission screw 60, and the support assembly 10. This not only achieves more stable guiding and positioning of the coil 90 through the double cooperation of the guide assembly 904 and the guide roller 901, improving the constraint effect and unwinding accuracy of the coil 90, but also effectively separates the guiding part from the transmission part through the modular structural design, avoiding mutual interference. At the same time, it facilitates the individual maintenance or replacement of each component, further enhancing the reliability and practicality of the device.

[0028] In this embodiment, the guide assembly 904 includes: a first connecting plate 905; a second connecting plate 906, which is disposed at an angle to the first connecting plate 905 and is connected to the first connecting plate 905; a third connecting plate 907, which is disposed at an angle to the first connecting plate 905 and is connected to the first connecting plate 905, with one end of the third connecting plate 907 connected to one end of the second connecting plate 906; and a fourth connecting plate 909, which is disposed at an angle to the first connecting plate 905. A fourth connecting plate 909 is connected to a first connecting plate 905 and is set at an angle to a second connecting plate 906. The distance between the second end of the second connecting plate 906 and the second end of the fourth connecting plate 909 is less than the distance between the first end of the second connecting plate 906 and the first end of the fourth connecting plate 909. A fifth connecting plate 908 is set at an angle to a first connecting plate 905 and is connected to the first connecting plate 905. One end of the fifth connecting plate 908 is connected to the first end of the fourth connecting plate 909. The fifth connecting plate 908 is set at an angle to a fourth connecting plate 909 and is set parallel to a third connecting plate 907.

[0029] In this embodiment, the guide assembly 904 is connected to a second connecting plate 906, a third connecting plate 907, a fourth connecting plate 909, and a fifth connecting plate 908, which are arranged at an angle, via a first connecting plate 905. One end of the third connecting plate 907 is connected to one end of the second connecting plate 906 at an angle. The fourth connecting plate 909 is at an angle to the second connecting plate 906, and the distance between their second ends is less than the distance between their first ends. One end of the fifth connecting plate 908 is connected to the first end of the fourth connecting plate 909 at an angle and is parallel to the third connecting plate 907. This multi-connecting plate, multi-angle combination structure design can form a stable constraint space that adapts to the edge of the coil 90, enhances the guiding and limiting effect of the coil 90, and improves the guiding accuracy and stability. At the same time, the rigid structure of the multi-plate connection can improve the overall strength and durability of the guide assembly 904, adapt to the contact friction during long-term coil conveying, and further ensure the reliable operation of the device.

[0030] In one exemplary embodiment, the support assembly 10 includes: a support frame 101 connected to a progressive stamping die 80; a guide groove 102 correspondingly disposed to the guide base 903, one end of which is provided with a limiting protrusion, and the guide groove 102 and the limiting protrusion are engaged; and a support block 103 spaced apart from the guide groove 102, the support block 103 connected to the support frame 101, and the support block 103 movably connected to the output shaft of the rotary handle 30.

[0031] In this embodiment, the support component 10 is connected to the progressive stamping die 80 via the support frame 101. It cooperates with the guide groove 102 and the limiting protrusion at one end of the guide base 903 to achieve precise guidance and limiting of the movement of the first guide frame 20 and the second guide frame 70. Simultaneously, the support block 103 is connected to the support frame 101 and spaced apart from the guide groove 102, and is movably connected to the output shaft of the rotating handle 30, providing stable support for the rotating handle 30. This structural design ensures both the linear accuracy and stability of the guide frame movement and enhances the support strength of the rotating adjustment components, preventing swaying or deviation during adjustment. This further improves the structural rigidity and operational reliability of the entire device. Furthermore, the clear division of labor and compact connection of each component facilitates installation and maintenance.
