SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a can carry out the cutting device of the thick steel plate that cuts again to thick steel plate earlier in order to solve the not enough of above-mentioned technique.

In order to achieve the above purpose, the cutting device for thick steel plates comprises a frame, wherein a conveying roller for horizontally conveying steel plates is arranged on the frame, two vertical guide vertical rods are arranged on the frame, an upper knife holder is arranged on the guide vertical rods above the conveying roller, a lower knife holder is arranged on the guide vertical rods below the conveying roller, the upper knife holder and the lower knife holder both slide on the guide vertical rods, a vertical downward hydraulic cylinder is arranged on the frame above the upper knife holder and drives the upper knife holder to move on the guide vertical rods, a vertical upward hydraulic cylinder is arranged on the frame below the lower knife holder and drives the lower knife holder to move on the guide vertical rods, an upper cutting knife is arranged on the lower surface of the upper knife holder, a lower cutting knife is arranged on the upper surface of the lower knife holder, the upper cutting knife is matched with the lower cutting knife, and horizontal guide cross rods are arranged on the frames on two sides of the guide vertical rods, the steel plate conveying device is characterized in that mounting seats are arranged on the two guide cross rods, a main shaft is arranged on the mounting seats, a cutting circular knife is arranged on the main shaft, belt wheels are arranged on the main shaft at the side edges of the cutting circular knife, motors are arranged on the mounting seats, the motors are in transmission connection with the belt wheels, the edge of the lowest end of the cutting circular knife is located below the horizontal position of the upper surface of a steel plate on a conveying roller, and a power mechanism is arranged between the mounting seats and the guide cross rods and drives the mounting seats to move on the guide cross rods in a reciprocating mode.

Above-mentioned technical scheme, in actual course of working, the steel sheet is placed and is carried forward on the conveying roller, carry and stop after a locating position, then cut on the steel sheet surface through the cutting circular knife on the mount pad earlier, in-process when mount pad reciprocating motion on the direction horizontal pole, the realization is to a recess of steel sheet surface cutting, and this recess is corresponding with last cutting knife and lower cutting knife, carry out the cutting process again, go up the cutting knife and just in time fall in the recess, thereby can reduce the steel sheet thickness of cutting department, so the damage of going up cutting knife and lower cutting knife is less in the cutting process, the incision is also more neat simultaneously. Meanwhile, the length of the guide transverse rod can be larger than that of the upper cutter holder, and after the groove is cut, the installation seat is located on one side edge, so that the upper cutter holder cannot be interfered in the descending process, and the running stability of the equipment is higher.

The hydraulic telescopic mechanisms in the vertical direction are arranged on the racks on the two sides of the lower cutter holder, and cushion blocks are arranged on the hydraulic telescopic mechanisms. The design of this structure can push up the cushion through hydraulic telescoping mechanism in cutting process to make it support the both sides of steel sheet cutting department, thereby ensure cutting process's stability, promote the cutting effect.

In addition, the thicknesses of the upper cutter and the lower cutter are consistent, the upper cutter and the lower cutter are general grooves cut on the surface of the steel plate by the circular cutting knife, the vertical projection of the upper cutter is located in the half range of the grooves, and the vertical projection of the lower cutter is located in the other half range of the grooves. Because the depth of the middle part of the cutting groove is deepest, the design of the structure can fully utilize the deepest position of the groove to cut the upper cutter and the lower cutter in a matching way, so that the cutting is simpler, and the cut is more tidy.

Can be provided with the stroke inductor in the frame of steel sheet top for respond to the steel sheet and carry the degree, thereby fix a position the cutting length of steel sheet, after reaching required length, hydraulic telescoping mechanism lifts up the cushion, ensures positioning accuracy.

The utility model provides a cutting device of thick steel plate, it can carry out the recess cutting earlier to the surface of thick steel plate, cuts again, can effectively reduce and cut thickness, ensures to cut the stability of thick steel plate, and the incision is neat.
