Using the SolidWorks automated design system, analytical studies of the “Turbula” type rolling machine with an additional movable rocker link with a vertical axis of rotation were carried out for the possibility of determining the dependence between the change in the movement modes of the working array and the design features of this rolling machine. It is noted that the movement of the working array in the filling tanks with different types of movement can be carried out in cascade, waterfall, mixed, as well as closed modes of movement. During the implementation of each mode of movement of the working array, conditions are created for the performance of appropriate felting technological operations or mixing of loose fine-dispersed substances. It was established that the change in the modes of movement of the working array in the rolling container performing complex spatial movement depends on three factors – the large-scale standard size of the rolling machine, the angular velocity of the drive shaft and the ratio of the interaxial distance of the container to the interaxial distance of the forks, which is characterized by the coefficient λ, the relationship is established the relationship between these factors. Mathematical dependencies have been obtained to determine the maximum angular speed of the drive shaft of the “Turbula” type rolling machine with an additional movable rocker link with a vertical axis of rotation, which will correspond to the implementation of the necessary mode of movement of the working array, when it moves in a given capacity. The obtained results of analytical studies can be used in the relevant design bureaus of machine-building enterprises at the stage of designing rolling equipment with complex spatial movement of working capacities.
The disadvantages of using machine mechanisms in the kinematic circuits of which contain a passive connection are described. A three-dimensional statically defined mechanism of the “Turbula” type machine without the presence of a passive connection in its kinematic circuit is proposed. This design of the machine is realized due to the introduction into the kinematic circuit of an additional moving link – the second working capacity. Operation of this design of the car allows to increase productivity of processing of details considerably due to the fact that there is a possibility on one car to carry out two different technological operations at the same time or to process two parties of various details at the same time. The principle of operation of the mechanism and the machine is described. Analytical researches of the basic geometrical and constructive parameters of the galvanizing machine with two working capacities which, as a whole, provide its rational functioning are executed. The relationship between the geometric parameters of the moving parts of the machine and the change in the amplitude of their movements. In particular, mathematical dependences are obtained, which make it possible to calculate the amplitude of the angle change between the axes of two tanks, as well as the amplitude of the distance change between mutually perpendicular geometric axes of the forks to the working tanks. The operation of this machine design will significantly increase the productivity of machining parts due to the fact that it is possible to perform two different technological operations on one machine or simultaneously process two batches of different parts. The obtained results of analytical researches can be used in the corresponding design bureaus of the machine-building enterprises at a stage of designing of the galting equipment with difficult spatial movement of working capacities.
A new design of the galvanizing machine is proposed, which is equipped with two working tanks that perform complex spatial movement. The structure and principle of operation of the developed design of the machine are accurately described. The developed design of the machine with two capacities that perform complex spatial movement allows to increase considerably productivity of processing of details due to the fact that there is a possibility to carry out two different thawing technological operations on one machine or to process two parties of different details at the same time. The design of the machine, during operation, allows to involve in working process, both both working capacities, and one. Equipping the machine with a special drive design with four Hook hinges allows to reproduce the required law of change of angular velocity on each driving shaft of the machine, the implementation of which will create conditions that will ensure the same intensity of the working array between opposite ends of the tank in opposite directions. process, as well as uniform dynamic loading of all moving parts. Analytical studies were performed, within which some geometrical parameters of the machine design were determined, in particular, the value of the angle α between the axes of the shafts of each Hook hinge was established, which will ensure the implementation of the required angular velocity law on the machine drive shaft. The relationship between the extreme values of the law of change of the angular velocity of the driving shafts of the machine and the magnitude of the angles in each Hook hinge is established. The obtained results of analytical research can be used in the relevant design offices of machine-building enterprises at the stage of designing galvanizing equipment with complex spatial movement of working tanks.
A method of wet polishing of polymer parts using a galvanizing machine with a complex spatial movement of the working tank type «Turbula» is proposed. According to the proposed method, the main stage of polishing the surface of the parts is carried out by abrasive ceramic bodies of complex geometric shape with the addition of fine pumice in the implementation of mixed cascade-waterfall mode of movement of the bulk working medium. This method of processing parts is considered highly productive, the processing time of parts averages 15 hours of continuous operation of the machine, which is several times faster than when processing parts in rotating drum drums or vibrating machines. The latter are characterized by low productivity of the relevant technological operations. The feasibility study of the method of wet polishing of polymer parts using a galvanizing machine with a complex spatial movement of the working capacity of the «Turbula» type for the implementation of the technological operation of polishing the surface of polyester buttons was performed analytically. The expected annual economic effect from the implementation of the developed method of wet polishing of polymer parts using a galvanizing machine with a complex spatial movement of the working capacity of the «Turbula» type, which will amount to UAH 14,059.8 per two units of equipment, is calculated. This method of processing can be used to improve the surface quality of any polymer parts with the possibility of achieving the appropriate value of the roughness of their surface. The obtained research results can be used in design bureaus of relevant enterprises for the manufacture of small polymer parts, the surface quality of which is determined by organoleptic method, as well as in design bureaus of machine-building enterprises specializing in the development of galvanizing equipment.
The types of shredding equipment used at domestic enterprises to perform the technological operation of separating parts from foundries are analyzed. It is established that machines with rotational movement of working tanks have low productivity of performance of these technological operations. In addition, a lot of time is spent on manual labor, in particular, reloading the working array to the vibrating screen. The design of the «Turbula» type galvanizing machine with complex spatial movement of the working capacity for the technological operation of separating metal parts from the foundries is proposed. This design of the machine is realized by combining in one design of the galvanizing tank (separation of parts from the foundries) and vibrating sieve (separation of separated parts from the foundries). Operation of such a structure allows to reduce the time spent on this technological operation, in particular, by providing convenient and unobstructed unloading of machined parts without the use of manual labor to overload the working array and further achieve separation of parts from foundries. The feasibility study for the use of «Turbula» equipment with complex spatial movement of the working capacity for the implementation of the technological operation of separating the metal parts of the “zipper” lock from the foundries was performed analytically. The expected annual economic effect from the introduction of the developed «Turbula» type machine with complex spatial movement of the working capacity to perform technological operations of separation of metal parts of the lock “lightning” from the foundries will be 25’688.7 UAH per unit of equipment. The developed design of the machine can be used for any type of parts (metal or polymer), which are formed by casting. The obtained research results can be used in the relevant design offices of machine-building enterprises at the stage of designing galvanizing equipment with complex spatial movement of working tanks.
