Embodiment 1

[0039] Such as figure 1 and figure 2 Shown, a kind of plate shearing machine comprises the frame 1 that is provided with feed end and discharge end, and the feed end of frame 1 is provided with bearing platform 2 along horizontal direction, and bearing platform 2 can be used for placing the steel that needs processing bring. The middle part of the frame 1 is equipped with a shearing mechanism 3 for shearing the steel strip on the bearing platform 2 . The shearing mechanism 3 includes a lower blade 5 and an upper blade 4 , and the lower blade 5 is fixedly connected to the frame 1 . Both ends of the upper blade 4 are provided with sliders 6 , which are embedded in the frame 1 and slidably connected to the frame 1 along the vertical direction. Furthermore, the upper blade 4 can only slide vertically relative to the frame 1 . Through the cooperation of the upper blade 4 and the lower blade 5, the steel strip is sheared.

Embodiment 2

[0056] Such as Figure 7 As shown, the difference between the second embodiment and the first embodiment is that the reversing mechanism 33 is different. The reversing mechanism 33 includes a driving gear 39 coaxially fixedly connected to the second shaft 28, a driven gear 40 engaged with the driving gear 39 and rotatably connected to the frame 1, a first rod 41 rotatably connected to the driven gear 40, The second rod 42 is rotatably connected to the push member 16 , and the second rod 42 is rotatably connected to the first rod 41 .

[0057] When the second shaft 28 rotates, the driving gear 39 rotates, and then drives the driven gear 40 to rotate; reciprocating motion. The reciprocating frequency of the pusher 16 and the reciprocating frequency of the upper blade 4 in the vertical direction can be realized by adjusting the number of teeth of the driving gear 39 and the driven gear 40, so that the shearing machine can more stably cut steel strips of equal width.

Abstract

The invention relates to the technical field of machining equipment, and particularly discloses a plate shearing machine. The plate shearing machine comprises a rack and a shearing mechanism mounted on the rack, wherein the shearing mechanism comprises a lower cutting edge and an upper cutting edge; the rack is connected with a driving shaft in a rotatable manner; a connection rod is arranged between the upper cutting edge and the driving shaft; the connection rod is eccentrically arranged relative to the axial line of the driving shaft; the rack is in sliding connection with a push piece forpushing a steel band to move forwards; the driving shaft comprises a straight shaft part and a rightwards-inverted U-shaped crankshaft part; the crankshaft part is connected with a connection sleeve in a rotatable manner; the outer wall of the connection sleeve is fixedly connected with a linkage rod; the rack is connected with a transmission shaft in a rotatable manner; a connection tab is arranged on the transmission shaft; the linkage rod is connected to the connection tab in a rotatable manner; and a reversing mechanism for converting a rotating pair of the transmission shaft into motion of the push piece along a lengthwise direction of the steel band is arranged between the transmission shaft and the push piece. When the driving shaft rotates, material feeding and shearing are carriedout synchronously, so that the steel band can be continuously sheared into steel plates with equal widths, the labor cost is reduced, and the shearing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of machining equipment, in particular to a shearing machine. Background technique [0002] The shearing machine is a kind of equipment with a wide range of uses, mainly used in the metal processing industry. It fixes the steel belt through the pressing frame of the shearing machine, and uses the relative movement between the upper and lower blades to cut metal of various thicknesses. The shear force is applied to the sheet, so that the sheet is broken and separated according to the required size. [0003] For example, the patent application number is CN200810014295.2, which discloses a multifunctional shearing machine, including left and right side plates, base, left and right motors, platen springs, upper knife rest, bottom knife rest; the upper knife rest is installed on the left and right sides In the large guide rail of the plate, the bottom knife rest is installed on the bottom of the left and right si...
