As shown in fig. 2, in the present embodiment, an incision portion 21 is provided at a position in the middle of the edge of the first cutter 02, and the incision line 212 is in a V-line shape.

Further, as shown in fig. 2, the cutting edges of the second cutter 03 and the first cutter 02 are the same in length, the guide surface 31 is disposed on one side of the cutting edge of the second cutter 03, and the cutting edge of the second cutter 03 protrudes toward the first cutter 02 to form an engaging portion 32 corresponding to the cut-in portion 21, preferably, the engaging portion 32 has the same shape as the cut-in portion 21 and corresponds to the cut-in portion 21 in position, and the number of the engaging portions 32 is the same as the number of the cut-in portions 21 and is opposite to the number of the cut-in portions 21. In this embodiment, a V-shaped linear matching portion 32 is disposed at the middle of the cutting edge of the second cutter 03. When cutting a sheet metal, the cut-in portion 21 and the engagement portion 32 are cut in from both sides of the sheet metal, respectively, so that the punching force of the driving device 04 can be further reduced, and the cutting quality can be improved.

Further, as shown in fig. 2, two sides of the first cutter 02 are also provided with a limiting block 05, and the limiting block 05 protrudes from the side surface of the first cutter 02; the two sides of the second cutter 03 are correspondingly provided with limiting side-proof blocks 06 for limiting the first cutter 02 by matching with the limiting block 05, the same limiting side-proof blocks 06 protrude out of the side surface of the second cutter 03, and the limiting block 05 and the limiting side-proof blocks 06 are positioned on the same side.

Stopper 05 and spacing side piece 06 of preventing have limit function: in the cutting process, the second cutter 03 is still, the first cutter 02 is pressed downwards towards the second cutter 03 along with the guide surface 31 of the second cutter 03 until the limiting block 05 contacts the limiting side-preventing block 06, and the first cutter 02 reaches the maximum pressing distance. Stopper 05 and spacing side piece 06 of preventing all adopt the bolt installation in this embodiment, and the maximum distance that pushes down passes through the mounted position adjustment, and the maximum distance that pushes down of settlement sets up according to the thickness setting of the panel beating of cutting.

The limiting side-proof block 06 has a side-proof function for the first cutter 02: the limiting side preventing blocks 06 are arranged on two sides of the second cutter 03, the limiting side preventing blocks 06 extend to two sides of the cutting edge of the second cutter 03, in the process that the first cutter 02 is pressed down along the guide surface 31, the cutting edge of the first cutter 02 is limited by the limiting side preventing blocks 06 on two sides of the guide surface 31 and can only be pressed down along the direction of the limiting side preventing blocks 06, and therefore the situation of side deviation during cutting caused by the fact that the cutting edge of the first cutter 02 is not parallel and level can be effectively prevented.

Further, as shown in fig. 3 to 5, the sheet metal cutting device further includes a first cutter holder 07 and a material pressing plate 08; the first cutter holder 07 is mounted on the driving device 04, the first cutter 02 is mounted on one side of the first cutter holder 07, the material pressing plate 08 is mounted at the end of the first cutter holder 07 through the elastic piece 09, a compressible gap a is reserved between the material pressing plate 08 and the first cutter holder 07, and the material pressing plate 08 contacts the metal plate before the cut portion 21 during cutting.

Specifically, drive arrangement 04 is telescopic cylinder, and first cutter seat 07 passes through the connecting plate 010 to be installed at telescopic cylinder's piston rod lower extreme, and the piston rod stretches out downwards during the cutting, drives first cutter seat 07 and installs the pressure flitch 08 and the first cutter 02 on first cutter seat 07 and pushes down simultaneously and cut.

Referring to fig. 3 and 4, the first cutter 02 is installed on one side of the first cutter holder 07, the pressure plate 08 is installed at the lower end of the first cutter holder 07, and the lower end of the pressure plate 08 is parallel to the blade of the first cutter 02.

Referring to fig. 5 again, fig. 5 is a cross-sectional view taken along line a-a in fig. 3, showing an internal structure of the first cutter holder 07 and an installation manner of the pressure plate 08: in the drawing, the upper end is a first cutter holder 07, the lower end is a pressure plate 08, a plurality of hollow columnar holes 71 are arranged in the first cutter holder 07 along the downward pressing direction of the first cutter 02, and the upper ends of the columnar holes 71 are provided with threaded holes 72 with the aperture smaller than that of the columnar holes 71; a plurality of hole columns 81 with internal threads are protruded at the upper end of the pressure plate 08, and the hole columns 81 are communicated with the pressure plate 08; a bolt 82 is inserted from the lower end of the pressure plate 08, passes through the hole post 81 and the columnar hole 71, and is fixed in the threaded hole 72, and the pressure plate 08 and the hole post 81 are movable along the bolt 82.

Further, an elastic member 09 is sleeved outside the bolt 82, the upper end of the elastic member 09 abuts against the inside of the columnar hole 71, the lower end of the elastic member 09 abuts against the outside of the hole column 81, the elastic member 09 provides downward elastic force to the pressure plate 08, and a gap a is reserved between the pressure plate 08 and the first cutter holder 07 in a state that the pressure plate 08 is not extruded by external force. When the sheet metal is cut, along with the downward pressing of the first cutter holder 07, the pressure plate 08 contacts the sheet metal in advance of the cut-in portion 21, the pressure plate 08 stops downward pressing, at the moment, the elastic piece 09 is compressed, the second cutter holder 07 and the first cutter 02 continue to be pressed downward for cutting, and the gap a is gradually reduced. Therefore, the gap a between the material pressing plate 08 and the first cutter holder 07 needs to be larger than the thickness of the cut sheet metal. The pressure plate 08 in this embodiment will push down the panel beating before the cutting, prevents that the panel beating from rocking when the cutting, influencing the cutting quality.
