Disclosure of invention

An impact roller with adjustable impact force includes a longitudinal axis of rotation of the roller with a plane of symmetry perpendicular to the longitudinal axis of rotation and radially guided discrete and regularly arranged in parallel planes, rigidly fixed to the axial cylindrical element, the guiding rods being placed inside the shock elements and provided in the plane guide rods mounted on them by cantilevered protrusions with the possibility of temporary fastening of shock elements on them and with zhnosti free fall impact elements rolling down the roller, with the radial fixing of each guide rod to the inner surface of the roller. Each cantilever protrusion is made with the possibility of changing its position on the guide rod, and the shock element is made with the possibility of changing its mass.

Drop height and load weight determine the impact force. Changing these parameters allows you to set, depending on the task, the required impact force.

The implementation of the cantilevered protrusions paired with symmetry relative to the transverse axis of the guide rod parallel to the axis of rotation of the roller, allows both directions of rotation of the roller to make working.

The implementation of the invention

The shock roller 1 is a cylindrical shell with flat side elements of circular shape 2, the longitudinal axis of rotation of the roller with an axial cylindrical element 3, with a plane of symmetry perpendicular to the longitudinal axis of rotation (figure 1), and radially guided discretely and regularly in parallel planes in parallel planes rods 4 of circular cross section, fixed, for example, by welding to the axial cylindrical element 3 and to the shell, and diametrically arranged arranged in the guide rods 4 grooves 5, and the rods themselves are equipped with cantilevered protrusions 6, rigidly fixed to the ring 7, while the cantilevered protrusions 6 are paired with symmetry with respect to the transverse axis of the guide rod parallel to the axis of rotation of the roller, and are configured to move the ring 7 along the rods 4 and secured their clamping bolts 8 in the fixing recesses 5 on the rods 4, and on the cantilevered protrusions 6 can be temporarily fixed shock elements 9 with bolts 10 mounted on them by pair weighting agents 11 and 12, and in axial guide holes 4 are placed in the hole 13 of the impactor 9 and the semicircular cut-outs of the paired weighting agents 11 and 12 (FIG. 2).

Paired weighting materials are placed in height with a mutual rotation of 90 ° one 11 relative to the other 12.

The position of the impactor 9 when the roller is rolling on the surface to be machined, shown in FIG. 5, explains the operation of the roller. During one full revolution (the cycle is shown when the roller rotates clockwise), the following phases are determined:

“A” - the lowest position of the impact element relative to the guide rod after impact (φ = 0);

“B” - lifting of the shock element when the guide rod is rotated until this rod assumes a horizontal position, while the shock element retains position “a” on the guide rod, relying on it (0 <φ≤π / 2);

“C” - further rise of the shock element when it slides along the guide rod down to the axis of rotation (π / 2 <φ <π);

"D" is the extreme upper position of the shock element (φ = π);

“E” - for φ> π, the shock element is rolled over on the guide rod, and its sliding down is blocked by the left platform of the bracket and is fixed on the rod during its further rotation up to the value of the rotation angle φ≈2π;

“F” - at a certain value of φ≈2 tf, the shock element breaks off the bracket, it falls and hits the inner surface of the hollow roller.

Then the cycle repeats.

The impact on the inner surface of the roller is carried out by the fall of the shock elements, perceived by the roller, dynamically acting on the treated surface.

The impact force, if necessary, is changed by installing or removing weighting agents of type 11, 12, ..., as well as moving the ring 7 with a cantilevered protrusion and securing it in a new position.

The presence of two cantilevered protrusions allows for a working movement in both directions without turning the roller.
