Description

FIG

The invention relates to working media for volumetric vibratory processing and can be used in the mixing of powdered materials, as well as in the operations of finishing and stripping the surfaces of parts.

The aim of the invention is to increase the productivity of the mixing process of powdered combinations by increasing the number of workers. movements of the mixing elements granules

FIG. 1 shows the proposed granule, axonometric | FIG. 2 shows a section A-A in FIG. 1, FIG. 3, a mixing element; Fig 4 - mix the element bonded to the core.

The granule of the filler for volumetric vibration treatment contains strips t of curvilinear shape, installed in groups on the rod 2 with an angular rotation about one group of strips 1 relative to another. The strips are fixed to the rod 2 at one end 3, and the other are fastened with sleeves 4 installed with the possibility of reciprocating movement along the rod 2.

The manufacture and assembly of the described pellet is pelleted as follows.

The strips 1 are made of mixing elements, for example, by cutting out of a metal tape on a stamp, a rod 2 is made, for example, by turning on lathes, 4 sleeves are made, for example, by cutting a pipe on a cutting machine and placed on the rod 2 reciprocating movement, fastened with sleeves 4 strips 1 with uniform or uneven pitch around the circumference, for example, by welding. The sleeves 4 with the strips 1 are deployed relative to one another and the strips 1 are attached to the rod 2, for example, by welding. The granule is ready to work. The total width of strips 1 in one group along the circumference can be from three to six. When the number of strips 1 in one group is less than three, the performance of the granule deteriorates as the granule becomes flat, and if the amount exceeds six, the production of the granule becomes more difficult. The number of bands of bands 1 along the rod 2 can be from two to five

When the number of groups of strips 1 is less than two, the performance of the granule deteriorates due to the reduced possibility of the granule turning around its axis, and when the number of groups of strips 1 more than five complicates the production of the granule and the granule becomes longer. The shape of strip 1 is arcuate, while the center of the arc of strip 1. is located outside rod 2. The ratio of the thickness of strip 1 (fig. 2) to height h (fig. 3) can be both the same and different and can be within 0.05. - 0,25 and depends on the required performance characteristics of the granules. The width S (Fig. 3) of the strip t depends on the height h and can be taken equal to (0.1-0.4) h and is determined depending on the required performance characteristics of the granule. The amount of overlap of the groups of strips t along the rod 2 can be taken 0.2-0.5 L (L is the length of the stripe t), while it can be both the same and different in groups and is assigned depending on the required performance characteristics of the granule. , and also depending on the required dimensions of the granules. The diameter of the rod 2 can be taken equal to 3-tO mm and is assigned on the condition of ensuring the placement and reliable fastening of the strips 1 on the rod 2, the length of the sleeves 4 is taken to be (T-1,3.) S., and the wall thickness of the sleeve 4 can be taken equal to 0.1-0.5 of the diameter of the rod 2, are assigned, based on the placement and reliable fastening of the strip 1 with the sleeve 4 "The size of the gap between the sleeve 4 and the rod 2 is adopted, on the basis of the condition of mutual free return translational movement, and 0.5-1 mm can be received. When the gap is larger than 1 mm, the dimensions of the granule increase. The outer diameter of the granule can be 15-50 mm and depends on the dimensions of the working volume of the container in which these granules are placed, as well as on the composition of the working medium. The thickness (of the strips 1 of the mixing elements may be 0.1–3 mm and depends on the composition of the mixed mass - and is appointed, based on the condition of ensuring the strength characteristics of the granule. The length L of the strip 1 may be 10–50 mm

and depends on the performance of the granules, as well as the dimensions of the granules. One group of strips 1 relative to the other is turned around (/., The value of which depends on the number of groups of strips 1 and the number of strips 1 in a group and is 18-60). The rod 2 can be made with cones, while the angle of the cone can be taken to be 30-70 °, the angle of the cone can be assigned, based on the condition of ensuring the strength characteristics of the granule and high penetrating power.

For example, the granule contains a rod 2, made of steel 65G, with cone angles equal to 35 ° and with a diameter of 5 mm. The strips 1 are cut out on a stamp from a 65G tape with a thickness of 0.5 mM. The number of strips 1 in one group is four, the arrangement around the circumference is uniform through 90 °. The number of groups along the rod 2 is three; the size of the overlap groups of 7 mm; strip length 1-15 mm; strip height 10 mm; strip width 3 mm; the outer diameter of the granules 25 mm; the outer diameter of the sleeve D-8 mm; the size of the gap between the sleeve and the rod 2--0., 5 mm; sleeve length 4-3 mm; The angle of rotation of one group of strips 1 of mixing elements relative to another is 30 °. The fastening of the ends of 3 strips 1 with the rod 2 and the sleeve 4 - welding.

Use the proposed granules as follows

Production of granules and powders to be mixed is poured into the vibratory machine bunker. The machine's vibration device is turned on, the powders and granules are mixed, moving with each other relative to each other. After the mixing is completed, the vibration device is turned off and the separation is made from the powder, for example, by means of separating screens-sieves. In the process096216

All the processing strips 1 have the ability to make additional movements in the form of twisting of the parts of the strip 1 fastened with the sleeve 4, i.e. make elastic circumferential oscillations, and also have the opportunity to change the outer diameter of the strips 1 row, with the possibility of elastic reciprocating, Q starting movement with a small amplitude of the sleeves 4 along the rod 2.

The use of the proposed filler granule for volumetric vibration treatment allows to increase, 5 the productivity of the mixing process of powder compositions as a result of additional movements of both the granule and mixing elements due to the possibility of their making with the ends of reciprocating movement with a small amplitude and, accordingly, elastic twisting, as well as increasing the penetrating power of the granule by 25 due to the combination of the shape of the granule and xa. Additional motions caused by vibrational vibrations.
