Abstract

The invention relates to the processing of metals by pressure and can be used in the blanking production of engineering enterprises for the separation of rolled metal into blanks. The purpose of the invention is to simplify the design of scissors and reduce their metal consumption. The movement of the lever 2 under the action of the ram 4 causes the insert 8 to move until the blade 10 contacts the rental lying on the knife and is transmitted through the hinge 6 to the insert 7, and also through the axis 1 moves the clamping insert before contact with the rental. Further movement of the lever 2 leads to clamping the car with the clamps with a force proportional to the cutting force, and to the separation of the cut workpiece. At the end of the cutting, the lever 2 and the liners are returned to their original position by the action of the ram 4 and the springs. 4 il.

The invention relates to the processing of meta. I. Ion pressure and 1 can be used in the blanking production of engineering enterprises for the separation of n) okata into blanks.

The purpose of the invention is to simplify the design of scissors and reduce their metal consumption.

FIG. 1 shows scissors for cutting rolled, shear, view; in fig. 2 - the same plan; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. one.

The shears for cutting steel contain levers 2 and 3 mounted on axis 1, the ends of which are interconnected by a power cylinder 4. Levers 2 and 3 are made with cylindrical bearing surfaces whose axes are parallel and displaced one relative to another in the plane passing through the axle 5 of the supply of the rolled steel and the axis of the hinge 6. The clamping mechanism of the rolled metal in the scissors is made in the form of levers 7 and cutting-8 inserts installed on the supporting surfaces, not fit (their pressure points 9 and the knife 0 are respectively).

interconnected by a hinge 6. The clamping mechanism of the cut-off workpiece is made on the 1I1de of the pressure pad 1 1 with the clamp 12 having a cylindrical surface. Contribution 1 I is conjugated with axis 1 along a circular arc. The knife 13 of the mechanism for clamping the cut-off workpiece is mounted on 1) 1 step 3. The springs 14 and 15 serve to install the elements of the scissors into the initial position.

and a cutting insert, made with reciprocal cylindrical surfaces and interconnected by a specified hinge, the first of which is mounted on an axis, as well as a clamping mechanism for the cut-off workpiece, including a pressing insert, made with a cylindrical surface and adjoining to axis, and a knife, characterized in that, in order to simplify the design and reduce metal consumption, the clamping of the clamping insert of the mechanism for clamping the workpiece to be cut with the axis is made along an arc of a circle, and the knife is mounted on one of the levers.

the insert 8 to the contact of the knife 10 with the rolling lying on the knife 13 is transmitted through the hinge 6 to the insert 7, and also through the axis 1 causes the movement of the insert 11 to the contact of the pressing 12 with the rental. Further movement of the lever 2 leads to the clamping of the rolled clamps 12 and 9 with a force proportional to the cutting force, and the separation of the cut piece. At the end of the cutting, the lever 2 and the inserts 11, 7 and 8 under the action of the power cylinder 4 and the springs 14 and 15 return to their original position.
