Description

The invention relates to a finishing-stripping and hardening processing of parts in a free granular medium and can be used in mechanical engineering, with dimensionless processing of parts.

A tumbling device is known (USSR AS No. 1743820, class B24B 31/02/1992), containing a multi-section drum, the side surface of each section of which is made by alternately connected rectangles and parallelograms, with the formation of square sections along the ends, while the square of each subsequent section is rotated relative to the square of the previous one at an angle of 90 °, with the formation on the surface of the drum of zigzag lines with a constant step along the length of the drum and a constant size of the passage section of the drum, the position of which is relative to si rotation unchanged, which leads to a certain stationarity of the movement of flows and limits the increase in processing intensity.

A disadvantage of the known device is the lack of processing intensity and limited technological capabilities.

Closest to the proposed invention is a device for finishing and hardening processing (RF patent No. 2528291, class B24B 31/02, publ. 09/10/2014, bull. No. 25), containing equipped with a drum drive, made in the form of a spiral tunnel shape, fixed with the possibility of rotation on a platform mounted elastically on the bed, loading and unloading devices.

A disadvantage of the known device is the lack of processing intensity and limited technological capabilities.

The technical result is the expansion of technological capabilities and increase the intensity of finishing and hardening processing.

The technical result is achieved by the fact that in the installation for finishing and hardening processing, comprising a drum mounted on the platform, mounted elastically on the bed, loading and unloading devices, a drum rigidly mounted on the platform, is equipped with a vibrator mounted horizontally below the platform and made of spiral a hollow tunnel with a multiple helical surface along the perimeter, rolled along a spiral axis 0 ₁ -0 ₁ around a central straight axis 0 ₂ -0 _{2 of a} spiral drum equipped with screws grooves inside at an angle to its spiral axis in the form of pockets of a triangular shape, alternately inside and outside the cross section of the hollow tunnel, and assembled from sections in the form of rings of the same shape and size, rolled from the same diamond-shaped stripes on which the trapeziums are placed, the sides of which are located on the sides of the rhomboid strip, and the upper and lower bases of the trapezoids are arranged at an acute angle to the axis of symmetry of diamond stripes 0 ₃ -0 ₃ and fold lines are located on The distance from each other equal to the length of the triangular shaped pockets along the inner surface of the hollow tunnel spiral shape, wherein the section in the form of rings interconnected sides of trapezoids.

According to the patent literature not found a technical solution similar to the claimed, which allows us to judge the inventive step of the installation for finishing and hardening processing.

The novelty is that the installation of a vibrator under the base with the drum provides a path of oscillation of the drum along with the machined parts of the processed medium in the form of a vertical ellipse, which ensures an increase in the specific gravity of the total kinetic energy (E _n ) and increases productivity.

The novelty is that the spiral drum with a multi-start screw surface around the perimeter is equipped with screw grooves inside and outside at an angle to the spiral axis of symmetry 0 ₁ -0 _{1 of the} hollow tunnel of a spiral shape with a central rectilinear axis 0 ₂ -0 ₂ , which increases the performance of dewatering and expands technological capabilities.

The novelty is that the spiral grooves of the spiral drum are made in the form of pockets of a triangular shape with centers of curvature located inside and outside the cross section of the hollow tunnel, which expands technological capabilities and increases the productivity of finishing and hardening processing.

The novelty is seen in the fact that the spiral drum is assembled from the section in the form of rings of the same shape and size, rolled up from the same diamond-shaped stripes, on which trapeziums are located on the sides of the diamond-shaped strip, and the upper and lower bases of the trapezoid are at an acute angle to the axis of symmetry rhomboid strip ₃ -0 0 ₃ and fold lines are located at distances from each other equal to the length of the triangular shaped pockets along the inner surface of the hollow drum helical tunnel, with the sections in the form of a rings connected to each other sides of the trapezoid, which increases productivity finishing and hardening treatment.

The novelty of the proposal also lies in the fact that along the entire perimeter of the spiral drum, the passage section varies not only in shape, but also in area, which provides alternate compression and expansion of flows of processed parts and particles of working media in each section of the spiral drum, increases productivity and extends technological opportunities.

The novelty of the invention lies in the fact that the trapezoid of the diamond-shaped strips from which the sections are mounted are differently inclined not only to each other, but also to the axis of symmetry of the spiral drum, therefore, the compression rate of the particles of the processed parts and particles of the working medium increases and the process of finishing and hardening is intensified .

The novelty lies in the fact that the drum is made of sections, the walls of which are differently inclined not only to each other, but also to the direction of the rotational movement of the flows of the workpieces and particles of the processed media moving under the influence of vibration in planes perpendicular to the passage section of the drum, this complicates the trajectory their movement and increases the intensity of processing and expands technological capabilities.

The invention is illustrated by drawings, where in FIG. 1 shows an installation for finishing and hardening processing, general view; in FIG. 2 is a section AA in FIG. one; in FIG. 3 - a visual image of a spiral drum with pockets of a triangular shape; in FIG. 4 - a visual representation of the relative position of the spiral 0 ₁ -0 ₁ , along which a hollow tunnel with a multiple helical surface is rolled around a central straight axis 0 ₂ -0 ₂ ; in FIG. 5 - one of the diamond-shaped strips on which trapezoids are placed, the upper and lower bases of which are located at an acute angle to the axis of symmetry of the strip 0 ₃ -0 ₃ in the form of fold lines; in FIG. 6 - a rhomboid-shaped strip bent along the fold lines to the upper and lower bases of the trapezoid; in FIG. 7 - one of the diamond-shaped stripes, rolled into a ring.

Installation for finishing and hardening processing (Fig. 1, Fig. 2) contains a drum 1, rigidly mounted on the platform 2, which is resiliently using four rubber-cord cylinders 3 mounted on the base 4. On the platform 2 is rigidly fixed boot device 5, and from below to the platform 2 is also rigidly attached to the vibrator 6 with a horizontal axis of rotation.

Installation for finishing and hardening processing is equipped with a discharge device 8 for receiving processed parts and particles of the working environment using the slice 7.

The vibrator 6 is mounted horizontally under the platform 2 and therefore provides the movement of the workpieces and particles of the working media inside the drum 1 under the influence of the vibrator 6 along elliptical trajectories.

The drum 1 (Fig. 1, Fig. 2, Fig. 3) is made spiral. In FIG. 4 shows a visual representation of the relative position of the axis of the spiral - the center of the axis of symmetry 0 ₁ -0 _{1 of the} hollow tunnel of the spiral drum 1 (in Fig. 4, the spiral drum is shown in cross sections 9 of the hollow tunnel with a multiple helical surface) and the central straight axis 0 ₂ -0 _{2 of the} spiral drum 1.

Thus, along the perimeter, the spiral drum 1 is made in the form of a spiral-shaped tunnel with a multi-helical surface along the perimeter and is provided with screw grooves inside and outside, located at an angle α to the axis of symmetry of the spiral 0 ₁ -0 _{1 of the} center of symmetry axis (Fig. 3) of the tunnel spiral, coiled 0 ₁ -0 ₁ around the central axis 0 ₂ -0 _{2 of the} spiral drum 1.

The helical grooves of the spiral drum 1 are made in the form of pockets 10, 11, 12, 13, 14, 15 on the inner surface and pockets on the outer surface 16, 17, 18, 19, 20, 21 of the spiral shape tunnel (Fig. 4) in the form of pockets triangular in shape, located inside and outside the cross section of the hollow tunnel, and assembled from the section in the form of rings 22 identical in shape and size, connected to each other by the lateral sides 23 and 24.

The result is a hollow tunnel of the spiral drum 1 (Fig. 1, Fig. 2, Fig. 3) with the axis of the spiral - the center of the axis of symmetry 0 ₁ -0 _{1 of the} spiral drum 1, twisted around the central straight axis 0 ₂ -0 _{2 of the} spiral drum 1 diameter D _cp with the formation of a spiral drum 1 with an outer diameter of D _max and an inner diameter of D _min (Fig. 4).

In this case, the hollow spiral drum 1 with a multi-helical helical surface is provided with helical grooves in the form of triangular pockets 10, 11, 12, 13, 14, 15 and triangular pockets 16, 17, 18, 19, 20, 21 along the outer surface of the spiral drum 1 (Fig. 4).

Thus, a hollow perforated tunnel with its own spiral axis of symmetry 0 ₁ -0 _{1 is} folded along this spiral 0 ₁ -0 ₁ around a central rectilinear axis 0 ₂ -0 ₂ and form a spiral drum 1 (Fig. 4).

Section 22 is made in the form of a ring (Fig. 7), mounted from a diamond-shaped strip 25.

Trapeziums 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37 are placed on the diamond-shaped strip 25, the sides of which are located on the sides of the diamond-shaped strip 25, and the upper and lower bases of these trapezoids (Fig. .5) are located at an acute angle β to the axis of symmetry of the diamond-shaped strip 0 ₃ -0 ₃ and are fold lines 38 (Fig. 5, Fig. 6), pockets of a triangular shape (Fig. 7) of the spiral drum 1, made in the form of a hollow tunnel .

In FIG. 5 shows the trapezoid:

first trapezium 26 with upper base AB;

second trapezoid 27;

third trapezoid 28;

fourth trapezoid 29;

fifth trapezoid 30;

sixth trapezoid 31 with the lower base of the VG.

At the same time, AB is the smallest of all the upper bases of the trapezoid located on the diamond-shaped strip 25 below the fold line of the SH and the above three trapeziums (first 26, second 27, third 28, fourth 29, fifth 30, sixth 31), and SH is the largest of all the lower bases of the trapezoid 26, 27, 28, 29, 30, 31.

In FIG. 5 also shows the trapezoid:

seventh trapezium 32 with the lower base of the VG;

eighth trapeze 33;

ninth trapezoid 34;

tenth trapezoid 35;

eleventh trapezoid 36;

twelfth trapezoid 37 with the upper base of CD.

At the same time, CD is the smallest base of all the upper bases of the trapezoid located on the diamond-shaped strip 25 above the VG fold line, which for all trapezoids, in turn, is the largest of all the lower bases from the seventh trapezium 32 to the twelfth trapezoid 37.

Thus, the fold line of the VG is not only the lower base of the trapezoid 31, but also the longest base of the trapezoid 32 and the longest of all the lower folds of the diamond-shaped strip 25 and ring 22 (Fig. 7).

In this case, the fold lines AB and CD are the shortest of all the fold lines of the diamond-shaped strip 25 and ring 22, with AB = CD.

The ratio of the length of the fold line of the VG and AB (SP) determines the value of the step S _{1 of the} spiral 0 ₁ -0 ₁ , and hence the step of winding the hollow tunnel around the straight axis 0 ₂ -0 _{2 of the} spiral drum 1.

For example, in FIG. 5 fold lines L ₁ <L ₂ <L ₃ <L ₄ <L ₅ <L ₆ <L ₇ and L ₁₃ <L ₁₂ <L ₁₁ <L ₁₀ <L ₉ <L ₈ <L ₇ .

The diamond-shaped strip 25 is bent along straight fold lines, which are the base of all twelve trapezoidal and parallel to each other (Fig. 5 and Fig. 6).

Then, the strip 25 is bent along the fold lines L ₂ , L ₃ , L ₄ , L ₅ , L ₆ , L ₇ , L ₈ , L ₉ , L ₁₀ , L ₁₁ , L ₁₂ (Fig. 6) and then collapses into a ring 22 (Fig. 7) with triangular pockets. Sections in the form of identical rings 22 are then connected to each other sequentially by the lateral sides 23 and 24 so that all fold lines are a continuation of the fold lines of the same ring of the previous ring.

Thus, the spiral drum 1 (Fig. 1, Fig. 2, Fig. 3) is made around the perimeter in the form of a multiple helical spiral surface around the perimeter of the spiral drum 1 with helical grooves inside and outside the spiral drum 1 in the form of pockets of a triangular shape 10, 11 , 12, 13, 14, 15 on the inner surface and helical grooves on the outer surface 16, 17, 18, 19, 20, 21 at an angle α to the spiral axis of the hollow tunnel of the spiral shape of the spiral drum 1.

Installation for hardening treatment works as follows.

The disturbing force of the vibrator 6 through the walls of the platform 2 and the drum 1 is transmitted to the workpieces and particles of the working particles inside the drum 1 and entering the drum 1 in a continuous flow through the loading device 5. The workpieces and particles of the working media rotate along vertical elliptical trajectories, when which is the process of processing. At the same time, the processed parts and particles of the working media not only intensively interact with each other, but also under the influence of vibration, rotate in a plane perpendicular to the through section of the drum 1. Since the dimensions of the cross section along the length of the drum 1, their shape and location are aggravated disruption of the movement of the processed parts and particles of the working medium, which in this case, interacting with the walls of the drum 1, are moved from loading to unloading. The presence of a drum 1 of screw surfaces around the perimeter of the drum 1 contributes not only to the complication of the motion paths of the workpieces and particles of the working media of particles, but also to the movement along the passage section of the drum 1 towards the discharge side.

When particles move, the workpieces and particles of the working media along the bore of the drum 1 due to changes in the bore in shape and size alternately form compression and vacuum zones in each section of the drum 1 over its entire volume, which also intensifies the processing of parts and expands technological capabilities . The processed parts and particles of the working medium, through the unloading window 32, are discharged using the slice 7 into the tank 8.

The technical and economic advantages of the installation for finishing hardening arise due to the implementation of a spiral-shaped drum with helical surfaces, in the form of triangular pockets, which ensures reduction in length, expansion of technological capabilities, increase in productivity and path (length) of movement of workpieces and particles working environments.

Technical and economic advantages also arise due to the installation of a vibrator horizontally below the platform with a drum and a change in the shape of the trajectory of the workpiece and working medium particles in the form of a vertical ellipse, which ensures an increase in the specific gravity of the total kinetic energy (En) and increases productivity.
