Abstract

The invention relates to the shaft of the flax-felt industry, in particular, to the production of gross footwear, and improves the quality of the base by preventing deformation of the surface of the workpiece and uneven compaction. The device is additionally equipped with a frame fixed on the edge of the cutout of the stencil, the height of which is equal to the sum of the thickness of the folded edge of the base and its radius of curvature. The plate with the stamp through the cutout in the stencil, the shape of which corresponds to the shape of the stamp, is lowered to contact with the workpiece and give it an oscillatory motion. In this case, the elastic preform is compressed by the action of a punch by a larger amount than by a stencil, and in the gap between the edges of the punch and the notch there is no accumulation of fibers. Under the action of the frame, the fibers of the workpiece slide along the clamped cover, which ensures a sufficient degree and uniformity of compaction, and the clamping of the free edges of the workpiece prevents deformation of the surface layer of the free edges of the workpiece. 1 il.

Description

Reta 7 with a gap between the edges of the stamp and the notch, the value of which is equal to the amplitude of the upper plate 2. The edge of the cutout of the stencil 7 is fixed to the frame 8, the height of which is equal to the sum of the thickness of the two free edges of the base 5 and its radius of curvature. The frame faces the bottom plate of the device. The device works as follows.

The cotton blanking of the base 5 folded twice on the cover 4 is placed on the bottom plate 1 and fixed by applying a stencil 7, while the edge of the frame 8 presses the edge of the cover 4 between the layers of the double folded base blank 5 to the bottom plate 1.

Plate 2 with a stamp 3 through the cutout of the stencil 7 with the frame 8 is lowered to contact with the workpiece 5 and give it an oscillatory movement in the transverse direction. Under the action of the elastic stamp 3, the billet is compressed by a larger amount than with the stencil 7. Due to this distribution of the compression of the billet in the gap between the edges of the punch 3 and the notch equal to the amplitude of the oscillations of the upper plate 2, no accumulation of fibers is formed. Under the action of the frame 8 layer of fibers,

Closed to the stamp 3, it slides a little on the clamped cover 4, which ensures a sufficient degree and uniformity of compaction both on the outer and the inner surface of the base, and the clamping of the free edges of the workpiece 5 prevents deformation of the surface layer of the free edges of the workpiece.

The output value of the specified height of the frame 8 in the direction of decreasing leads to the deformation of the surface layer of the edges of the workpiece, and in the direction of increasing - to the need for readjustment of the device. The presence of the frame protects the workpiece from deformation and eliminates the unevenness of its compaction.
