Definitions
- the present patent application consists, as its wording indicates, in a "MACHINE FOR THE FINISHING NON-MAGNETIC PARTS ", including new construction characteristics, conformation, design and services fulfill, with a maximum of safety and efficiency, the function for which it has been specifically screened.
- electromagnetism By electromagnetism, first of all, magnetism produced by an electric current and also the field of electricity which jointly studies electrical and magnetic phenomena, united to form a synthesis in which the current flow is in reciprocal link with magnetic phenomena mentioned.
- the basis of the system that operates the machine recommended consists of the magnetic field static, produced by electromagnets or magnets permanent and rotating at peripheral speed the better suited to the tank that contains the magnetic mass and antimagnetic parts in a liquid medium, where small abrasive parts in the form of triangles and non-magnetic cylinders are added.
- the function of the field magnetic is to properly retain mass magnetic contained in the rotating tank which, at the same time under the effect of centrifugal force, transports the non-magnetic parts and mass in a medium liquid, prepared to facilitate action in each case wanted on the parts that we treat.
- the retention of the magnetic mass causes a turbulence in the mass and non-magnetic parts, unexpected results that can be achieved during of the process, for example polishing, burnishing and cleaning of the parts located inside the tank, all because of turbulence and friction caused by the difference in speeds between the mass non magnetic and non magnetic parts to be treated and the non-magnetic abrasive parts that surround the rooms.
- the rotation speed of the tank must be the optimal speed for the type of parts to be treated and it may be unique for a determined diameter thereof, since the peripheral speed determines the force centrifugal required.
- the introduction of an adjustable system speed variation allows the use of different diameters and also greater control of the degree of finish for various types of parts, in depending on the intrinsic nature of these.
- the rotation speed of the tank is controlled through a reducer coupled to the output of an electric motor, which allows to coordinate the rotation speed of parts introduced inside this tank, by relative to the weight, dimensions, shapes and materials of these and the nature of the liquid introduced, thanks to what benefits obtained in this machine keep their percentage of effectiveness in relation to this weight, these dimensions and nature of the materials introduced to inside of it, without any limitation of load as in the case of machines existing on the market.
- the striated central support of the tank slides on the keyed axis of the vertical axis of the motor / gearbox and, once stopped, you can insert and extract it easily to rinse or empty the tank.
- the rotation of the tank can be transmitted in directly coupling it to the vertical axis of a motor, but since the required rotational speeds do not are not high it is better to do it through a reduction, which provides more rotational force to the axis, while the power and the size of the engine are which significantly reduces the machine size.
- a striated central hub which slides on the axis keyed to the vertical axis of the gearmotor and can, a when stopped, be easily inserted and extracted for rinse or empty the tank, a cylindrical housing with internal thread having been partly machined upper, to be able to screw the cover corresponding and keep the tank closed, after the corresponding parts, cylinders and liquids have been put inside.
- Magnetic fields produced by magnets remain static and wrap strategically the environment of the rotary tank, a flat iron having to prevent the loss of magnetic field by the outer part of the environment or cylinder which contains the magnets, leaving a minimum space between the tank and the fixed cylinder which serves as their housing.
- Another purpose of the present invention is relates to improvements introduced in the subject of the main patent, which are based on the modification of the arrangement of the elements found inside the machine tank, tank in which finishes the non-finished parts magnetic.
- These changes consist of the introduction into the interior of this tank of a plate with radial arms, on which the chains are grafted in corresponding iron and whose purpose is to modify the state of movement of the parts introduced inside of the said tank, in order to increase the yield of the finishing operation, as we will explain in detail below.
- the processes that are carried out inside the machine rotary tank can be process said to be wet or dry.
- the non-magnetic mass is the one that acts on non-magnetic parts.
- Improvements introduced in the machine recommended consist of the integration of a support upper located freely on the axis of the tank and at from which the iron chains are suspended corresponding.
- the shape of the support as described below, has a series of arms extending so radial, at the ends of which are mounted the chains made of iron, which hang vertically from these arms and are located inside the machine tank and held against its wall by magnetic attraction outside.
- the machine operation is based on the rotation of masses and non-magnetic parts to be finished, which found mixed in liquid media or paraliquid or dry, inside the tank, which, by turning, as a result of the centrifugal force generated, keeps these masses stuck to its wall.
- Another additional improvements to the present invention is the fact of replacing the tank in methacrylate with its sheath, by another made in less thick stainless steel, 1 mm, and covered with a 3 mm anti-friction jacket, which reduces the total thickness and facilitates the passage of magnetic flux, thereby increasing the force retention of the magnetic mass inside the tank, which helps the flow not to lose as much intensity thanks to the presence of this shirt and its sheath; In this way, the machine becomes more efficient, the magnetic field inside the tank then being of a size greater than that existing in the original machine.
- Figure n o 1 corresponds to a cross-section in vertical and schematic projection of the recommended machine, with geared motor (12-13) and the random situation of several permanent magnets.
- Figure No. 2 is a top view in horizontal projection and diagrammatically in the tank (18).
- Figure No. 3 is a front view in vertical projection and exploded view of the machine.
- Figure n o 4 is a front view in vertical projection of a longitudinal section of the improved machine, where we can see the situation of the support (25) placed on the column (27) of the machine and from which are suspended the corresponding iron chains (32).
- Figure n o 5 is a top view in horizontal projection where we can see the shape characteristics of the star support (25) with arms (24).
- machine object of the present invention can become more versatile and more effective if we introduce a speed regulation and electromagnets with adjustable magnetic field.
- the machine advocated consists of a frame (10) constructed from a set of horizontal or vertical ramps, welded together, and provided (10) with lugs (11), which forms a rigid structure on which the various parts of the machine are mounted, like a conventional electric motor (12), the l the axis of rotation is coupled to a reduction gear (13), the connection opening (14) of which is secured by means suitable to the flat iron (23), using screws (23a) which penetrate into the bored orifices (23b) provided on this flat iron (23).
- the tank (18) is formed of an open cylinder, without upper base and whose lower base (18a) is occupied in the center by a striated hub (26-26a), which serves both supporting element of a threaded column (27) at both ends, the lower end of this column being screwed into the housing (31a) and the upper end on the nut (28), which passes through a small disc or cover (29), located on the base nonexistent of this tank (18), which allows the exit of parts to be treated introduced inside (18), when begins the polishing, cleaning and other.
- the striated hub (26) being coupled to the axis (21) of the reducer (13), through the housing (31a), by gravity.
- the magnets located at the base of the machine, in the lower part and outside of the tank (18), have been eliminated, while in the object machine of the invention, the magnets located in the cylinder exterior (15) and on its lateral surface (15a), have been increased considerably, going on to occupy almost the full height of (15a) and further, a magnet (16) has placed on the other (17) on the same level, which contributes to increasing the working margin of the cylinders magnetic introduced inside the tank (18), with pieces of abrasive and the parts to be treated.
- an iron plate (19), see figure n o 2 is placed on the posterior part of these, so that the magnetic field generated by them is significantly increased, the magnetic force created then being oriented towards the front, namely towards the axis (21) of the tank (18), thanks to which the metallic and magnetic cylinders are necessarily attracted with more force because of the increase in the magnetic field obtained; this allows an increase in efficiency of 30%, compared to machines which are part of the state of the art, in which the magnets are arranged at the base of the machine parallel to the base (18a) of the tank.
- the central part of the tank (18), namely the hub (26) has been designed in a slightly conical shape and with an upper base forming a beveled area (26a).
- Another of the additional improvements of this invention consists in replacing the methacrylate tank (18), which in the main patent had to be covered the corresponding sheath (33), by another tank (18), made of stainless steel with a bottom with two slopes (18a) and whose thickness will be approximately 1 mm, which, associated with the sheath thickness of approximately 3 mm, will that the total thickness that the field will have to cross magnetic produced by the magnets located on the body of the machine will go from 6 to 4 mm, thanks to which the size of the magnetic field created will be increased, which will develop the action exerted on the magnetic mass which is at the interior of (18).
