More specifically, in the present embodiment, the mounting base 16 is connected to the top of the piston rod 120 of the hydraulic cylinder 12, a guide rod 151 connected to the pressing plate 14 is provided on both sides of each end, the two guide rods 151 of each end share a pressing block 155, and the end of the mounting base 16 is fitted to the upper surface of the pressing block 155. Referring to fig. 13, when the lower cutting blade 11 is in the initial state, the mounting seat 16 is not lifted by the hydraulic cylinder 12, and the mounting seat 16 presses the upper surface of the pressing block 155, so that the spring 154 is compressed to the maximum extent, and the pressing plate 14 and the upper cutting blade 13 have the maximum distance therebetween. Referring to fig. 14, when the lower cutting blade 11 is in the upward-pushing state, as the mounting seat 16 is gradually pushed up by the hydraulic cylinder 12, the mounting seat 16 is synchronously moved upward until the pressing plate 14 presses the steel strip; the underside of the mounting base 16 is then released from the upper surface of the top pressing block 155 and the lower cutting blade 11 is pushed upward beyond the pressing plate 14 and cooperates with the upper cutting blade 13 to cut the steel strip.
As a preferred embodiment of the present invention, referring to fig. 14 and 15, the edge 110 of the lower cutting blade 11 is inclined. Thus, when the lower cutting blade 11 is lifted upwards and cooperates with the upper cutting blade 13 to cut the steel strip, the cut steel strip between the first upper cutting blade 131 and the second upper cutting blade 132 will automatically curl to one side and separate from the upper cutting blade 13.
Further, the cutting mechanism 100 further includes a scrap storage box 17 located on a lower side of the cutting edge 110 of the lower cutting blade 11, wherein a plane of an upper opening of the scrap storage box 17 is not higher than a plane of a cutter body of the upper cutting blade 13. Thus, the cut steel strip will roll down to the waste storage box 17 along the edge 110 of the lower cutting blade 11, and the waste material formed after cutting will not affect the normal operation of the cutting mechanism 100.
As a further preferred aspect of the present invention, the cutting mechanism 100 further has a guide groove 170 engaged with both ends of the mounting base 16 for guiding the mounting base 16 up and down. Specifically, referring to fig. 16, a first guide plate 171 and a second guide plate 172 are disposed at opposite ends of the mounting base 16, and a guide groove 170 is formed on each of inner side surfaces of the first guide plate 171 and the second guide plate 172, which are opposite to each other, to be engaged with a corresponding end of the mounting base 16.
In some embodiments of the present invention, the hydraulic cylinder 12 involved in the cutting mechanism 100 may also be replaced by a pneumatic cylinder or a cylinder driven by an electric motor.
It is to be understood that, referring to fig. 7 and 14, in order to facilitate the installation of the first upper cutting blade 131 and the second cutting blade 132, a top mounting bracket (not shown) is further disposed on the top of the cutting mechanism 100, and a mounting plate 18 is fixed on the bottom of the top mounting bracket, wherein the mounting plate is matched with the first upper cutting blade 131 and the second cutting blade 132 in shape, and the first upper cutting blade 131 and the second cutting blade 132 are installed thereon.
In order to facilitate the control of the cutting mechanism 100, as shown in fig. 2, a foot switch 19 for controlling the operation of the driving cylinder is further provided at one side bottom of the cutting mechanism 100.
For better understanding of the present invention, the following method for operating the steel strip flush joint apparatus with cutting mechanism 100 and welding mechanism according to the present invention is shown in conjunction with fig. 7, fig. 8, fig. 9, fig. 10, fig. 11, and fig. 12:
firstly, the tail part of a first steel belt 41 is placed in the cutting accommodating cavity 10, and the tail part is cut to form a straight edge; moving the tail portion of the first steel strip 41 toward the welding housing cavity 20 until the tail portion reaches above the second top plate 212; raising first top plate 211 to be higher than second top plate 212, and bringing the tail portion of first steel strip 41 close to first top plate 211 until it abuts against the straight side of first top plate 211; second top plate 212 is raised to clamp first steel strip 41 in cooperation with press-fit plate 22.
Then, the head of the second steel belt 42 is placed in the cutting accommodating cavity 10, and the head is cut to form a straight edge; lowering the first top plate 211 and moving the head of the second steel strip 42 toward the welding housing cavity 20 until the head comes into close contact with the straight side of the second top plate 212; first top plate 211 is raised to cooperate with press-fit plate 22 to clamp second steel strip 42.
And finally, starting a welding mechanism, and welding the joint position of the tail part of the first steel strip 41 and the head part of the second steel strip 42 by using the welding gun 25 so as to complete the welding action of the tail part of the first steel strip and the head part of the second steel strip.
