Description

one

The invention relates to cutting devices. And can be used for cutting THIN metals, zhbsty, paper, films, etc.

A device for cutting materials is known which comprises a fixed knife with a window for feeding material and cutting with an edge AND A MOBILE knife. The movable knife is mounted on an axis resting on the levers at an angle to the plane of the stationary HOi-ia and is spring-loaded with it elastically to it in the middle part. During the working stroke, the arms move. MOBILE. The knife rotates on the axis, with its cutting edge, moves along the PLANE of the stationary knife, cutting material fll.

A disadvantage of the known cutting device is the need to precisely adjust and set the knife in such a position so that its cutting edge is parallel to the plane of the fixed knife.

At the slightest inaccuracy of adjustment, the material is not cut, but me; It does not require stopping the device. And additional adjustment is required, which reduces the productivity of the process.

A device is known for cutting materials, in particular paper, containing a frame, a fixed izozh with a window for feeding material and a movable lioxi.

However, the well-known scissors also require the adjustment of the lowerness of the basement of the knife relative to a fixed

5 provide - cutting TOiiKoro material.

The aim of the invention is to improve the quality of cutting by self-aligning the movable knife with respect to the base.

th

With this goal, the stock is installed with the possibility of rotation around its axis.

The essence of the invention is illustrated in a drawing, where (Jinr. 1 shows the device under construction, general view; on. 2 - the same, side view. The cutting device has a frame 1 on which a fixed knife 2 with a window 3 is mounted for feeding material 4 and with the cutting edge 5, as well as the movable knife 6. The movable knife 6 with its cutting edge 7 is pressed against the flattened plane 8 of the fixed knife 2 to two springs 9, which can be installed both along the edges and and throughout the whole plane of the knife 6, the movable knife b by the hinge 10 is connected to the rod 11 moving in qi - live The guide rail 12 and the threaded connection 13 connected to the piston of the power cylinder 14. The rod 11 has the ability to rotate around its axis relative to the cylinder guide 12 and the power cylinder 14 and therefore the movable knife 6 is self-adjusting by its edge 7 through the action of the springs 9 plane 8 of the fixed knife 2. The cutting device operates as follows: The material, for example paper, 4 is fed into the window 3 of the fixed knife 2. Under the action of the power cylinder 14 through the threaded joint 11, moving into With the help of a hinge U opoo 6 04 for the movable knife 6, which is pressed by the springs 9 with its cutting edge 7 to the plane 8 of the stationary knife, the paper is cut. After cutting by means of the ram 14, the knife 6 is raised up, returning to its original working position. The proposed design of the cutting device with a self-aligning movable knife ensures reliable operation of the device, simplicity of its manufacture and assembly. The invention of the device for cutting materials, in particular paper, containing a frame that carries a fixed knife with a window for feeding material and a movable knife, is spring-loaded relative to a fixed knife and is pivotally connected to the 1st with a power rod, in order to improve the quality of the cut by self-rolling blade, the rod is installed with the possibility of rotation around its axis.
