Description

Technical Field

[0001] The invention relates to the technical field of steel strip processing, and in particular to a combined longitudinal and transverse shearing machine unit for steel strip processing. Background Art

[0002] Steel strip is a strip-shaped metal material with large length and width and small thickness. It has high dimensional accuracy and good surface quality, which makes it very suitable for applications that require fine processing. In the processing of steel strip, a longitudinal and transverse shearing combined unit is needed to realize multiple functions such as stripping and cutting of steel strip, so as to facilitate the segmentation of steel strip into different sizes. When in use, the steel coil is first transported by the coiler and loaded onto the uncoiler, and the rolled steel strip is unfolded by the uncoiler, and the unfolded steel strip is transported to the longitudinal and transverse shearing combined unit, so as to facilitate the longitudinal and transverse shearing combined unit to sequentially perform longitudinal slitting and transverse shearing of the steel strip, so as to segment the steel strip into different sizes;

[0003] However, most traditional longitudinal and transverse shearing combined units have poor limiting and positioning effects on the steel strip when slitting the steel strip longitudinally, which leads to large gaps in the steel strip after slitting, thereby generating a large traction force on the unslit steel strip. At the same time, due to the vibration caused by the rotation of the cutting roller during the slitting process, large errors are prone to occur at the cut of the steel strip, affecting the slitting accuracy.

[0038] The driving motor 7 is installed at the outer end of the side wall of the mounting seat 1, and the output end of the driving motor 7 is connected to a transmission belt 8. A second guide roller 9 located on the inner side of the upper end of the mounting seat 1 is installed at the upper end gap of the transmission belt 8.

Connecting frames 20 are installed on the outer sides of the front and rear ends of the adjustment block 19, and a first limiting plate 21 is fixedly installed on the upper right side of the connecting frame 20. The adjustment block 19 is connected to the connecting frame 20 in a sliding manner. The adjusting block 19 can slide with the connecting frame 20 while rotating. At this time, the two groups of connecting frames 20 can move relatively inside the lower side of the mounting seat 1 under the action of the adjusting block 19, so as to facilitate driving The first limiting plate 21 slides synchronously on the outer side of the second guide roller 9, so that the spacing between the two groups of first limiting plates 21 can be adjusted according to the size of the steel belt, so that the two sides of the steel belt can contact the first limiting plates 21 respectively, and the first limiting plates 21 can be used to limit and correct the steel belt before slitting to avoid the deviation of the steel belt. The first limiting plate 21 and the second limiting plate 22 are both rotatably installed with rollers 23 inside, and the steel belt contacts the rollers 23, which can ensure the smooth movement of the steel belt. The outer side of the connecting frame 20 is slidably connected to a fixed plate 24 fixed to the inner side of the mounting seat 1, and the fixed plate 24 is installed with a spring 25 connected to the first limiting plate 21. The fixed plate 24 has a good limiting effect on the movement of the first limiting plate 21, and the spring 25 can ensure the adjustment effect.

The fan 28 is started so that the fan 28 can suck air from the bottom of the steel belt through the wind slot 29 to assist in limiting the steel belt. At the same time, the connecting plate 26 is installed in the gap between the two groups of second guide rollers 9, and the highest point of the ball 27 is aligned with the highest point of the second guide roller 9. When the first limiting plate 21 limits the steel belt, the ball 27 is connected to the outer side of the lower end of the steel belt. At this time, the ball 27 can further ensure the stability of the steel belt moving on the second guide roller 9.

Before slitting, the guide frame 31 is installed one-to-one on the left side of the cutting roller 16, and the position of the guide frame 31 is adjusted according to the position of the blade structure. A limit block 34 located in the mounting shaft 30 is fixedly installed on the inner side end of the guide frame 31, and a groove structure matched with the limit block 34 is opened inside the side wall of the mounting shaft 30. The guide frame 31 and the blade structure on the outer side of the cutting roller 16 are arranged one-to-one on the left and right, and the upper end longitudinal section of the guide frame 31 is "F"-shaped. When adjusting, the guide frame 31 and the limit block 34 are separated. The first fixing bolt 33 is then rotated and inserted into the threaded grooves in the guide frame 31 and the mounting shaft 30 in sequence, so as to fix the position of the guide frame 31. At the same time, the limit block 34 can ensure the stability of the movement of the mounting shaft 30. When the steel strip moves to the right end of the cutting roller 16 through the second guide roller 9, the cutting roller 16 can cut the steel strip. The cut steel strip can be directly moved to the upper end of the guide frame 31, so that both sides of the steel strip can be located inside the guide frame 31, so that the guide frame 31 limits the cut steel strip to avoid excessive contact between the steel strip and the blade structure and vibration, thereby improving the precision of cutting and reducing the error at the steel strip incision. At the same time, the grinding block 32 contacts the side of the steel strip, which is convenient for preliminary grinding of the side of the steel strip and removing burrs on its side wall.

The steel strip cut by the cutting roller 16 can be moved to the inner side of the second limit plate 22 under the action of the second guide roller 9. At this time, the second limit The right end of the positioning plate 22 is inclined to gather the slit steel strip, and the steel strip is limited again under the action of the left end of the second limiting plate 22 to avoid the dispersion of the slit steel strip to produce a large gap, and to generate traction on the unslit steel strip to cause the steel strip to deviate. The second guide roller 9, the cutting roller 16 and the connection between the mounting shaft 30 and the mounting seat 1 are all provided with a fixing ring 37, which is convenient for installing the second guide roller 9, the cutting roller 16 and the mounting shaft 30 through the fixing ring 37, so as to facilitate subsequent disassembly and replacement;

A stop block 42 is installed on the right side of the front end of the mounting plate 39 through a damper, and a cutting table 43 fixed to the upper left side of the mounting seat 1 is arranged directly below the stop block 42. The cylinder 38 is then started to extend the cylinder 38 and drive the mounting plate 39 to move downward. At this time, the stop block 42 contacts the steel strip and presses the steel strip under the action of the damper, so that the blade body 40 can accurately shear the slit steel strip in the transverse direction.

[0044] A second fixing bolt 36 is provided inside the upper end of the fixing ring 37 connected to the outside of the installation shaft 30, and a threaded hole adapted to the second fixing bolt 36 is provided inside the installation shaft 30. Positioning blocks 35 are installed inside the front and rear ends of the installation shaft 30, and the upper ends of the positioning blocks 35 are connected to the fixing ring 37, and the guide frame 31 is connected to the installation shaft 30 in a sliding manner. When the cutting roller 16 needs to be disassembled and replaced, the first limit plate 21 can be adjusted to the farthest point by the adjusting block 19, and then the second fixing bolt 36 can be rotated to make the second fixing bolt 36 The first fixing bolt 33 is then rotated counterclockwise to cause the mounting shaft 30 to rotate in the fixing ring 37 and squeeze the positioning block 35, so that the positioning block 35 positions the mounting shaft 30.
