Abstract

The utility model relates to a three-dimensional space high-energy impact powder making machine, which is composed of an intermediate water cold grinding tank (1), a swaying rod (2), a bearing (3), a bearing seat (4), an eccentric axis wheel (5), a main spindle (6), a bearing stand (7) matching with a bearing, an elastic tightening device (8) and a water supply pipe (9). The high-speed rotation of the main spindle (6) drives the eccentric axis wheel (5) to rotate, and sequentially the intermediate water cold grinding tank (1) is driven to sway between front and back and between left and right. The utility model solves the difficult problem that the existing various homogeneous equipment can not grind the metal powder with the particle size between 0.3 and 1 micron, and solves the difficult problem that the grinded metal powder with the particle size between 0.3 and 1 micron is easy to be oxidized in the meanwhile.

Description

Three-dimensional space high-energy impact powder making machine

The utility model is a three dimensions high energy impact flour mill, is specially adapted to metal grinding is become the metal dust of 0.3-1 granularity.

The flour mill of at present known abrasive metal mainly contains airflow milling flour mill and rotary mill etc.The common drawback of these equipment is: the metal powder that grinds out is greater than 1 μ; The centrifugal force that equipment produces when rotate grinding easily causes the rotation critical value, make the equipment can't high speed rotating, has limited thinner that metallic particles is ground; Grinding all is in one dimension or the motion of two-dimensional coordinate direction, grinds insufficient.

The purpose of this utility model provides three dimensions high energy impact flour mill.This machine has: the metal dust that grinds out is mostly at 0.3-1 μ; Do not ground the restriction of rotating critical value; Can make the equipment high speed rotating, metal is because of the heating oxidation in the time of preventing to grind; Grinding is in the motion of three-dimensional coordinate direction, grinds very abundant.

The purpose of this utility model is achieved in that three dimensions high energy impact flour mill, is made of intermediate water cold grinding jar (1), rocking bar (2), bearing (3), bearing block (4), eccentric arbor wheel (5), main shaft (6), the bearing bracket stand (7) of being furnished with bearing, elasticity fastener (8), feed pipe (9).It is characterized in that, one of feed pipe (9) joins with the water source, the other end links into an integrated entity with the water cooling tube in the interlayer of intermediate water cold grinding jar (1), the supporting one of dressing up of the same bearing block of bearing (3) (4), there is the matrix holder on the same rocking bar of lower external face (2) top of intermediate water cold grinding jar (1) of charging aperture affixed, the bottom surface of rocking bar (2) is affixed with bearing block (4) upper surface that is fitted with bearing (3), eccentric arbor wheel (5) is the cylinder with diameter, eccentric arbor wheel (5) axially has one greater than zero degree, oblique through hole less than 90 degree, the same bearing in outer ring (3) the inner ring tolerance of eccentric arbor wheel (5) is equipped, outer ring, the same main shaft of oblique through hole (6) the middle part tolerance of eccentric arbor wheel (5) is equipped, the minimum tolerance in both sides of main shaft (6) is fitted with two bearing bracket stands (7) of being furnished with bearing, a same rocking bar (2) of a minimum elasticity fastener (8) is affixed, and the other end is fastened on the ground erecting bed of three dimensions high energy impact flour mill.Here said bearing (3) is ball bearing preferably.Here said elasticity fastener (8) is spring preferably.The making of three dimensions high energy impact flour mill and use mechanism are: drive main shaft (6) high speed rotating with high-speed electric expreess locomotive, and generally will be up to 1500-3000 rev/min.The main shaft of high speed rotating (6) drives is furnished with the bearing bracket stand (7) of bearing, eccentric arbor wheel (5) and bearing (3) inner ring with changeing.Because eccentric arbor wheel (5) tiltedly through hole causes eccentric arbor wheel (5) when rotating, its upper face is in height transition state (outer surface at other position also all is in the height transition state) all the time, therefore drive bearing block (4) and the affixed rocking bar (2) of same bearing block (4), and then drive the affixed intermediate water cold grinding jar (1) of same rocking bar (2) and rock from side to side together.Because the inertia force that the high speed rotating of main shaft (6) produces makes not produce reaction force with main shaft (6) with rocking bar (2) that changes and intermediate water cold grinding jar (1), and then causes rocking bar (2) and intermediate water cold grinding jar (1) to rock back and forth.Because intermediate water cold grinding jar (1) is to wave under the circular arc state when roll and pitch, polished metal powder in the intermediate water cold grinding jar (1) can be in constantly by the free drop state of dome at the bottom of the circular arc.So just finished the three-dimensional coordinate motion of the front and back up and down of three dimensions high energy impact flour mill.Feed pipe (9) is given the water pipe supply cooling fluid body in intermediate water cold grinding jar (1) interlayer, and purpose is to avoid heating under grinding at a high speed and cause polished metal powder oxidation.Elasticity fastener (8) be for prevent to make rocking bar (2) and intermediate water cold grinding jar (1) forwards or the rear fall down, its elastic purpose is to provide external condition in order self to seesaw.One of elasticity fastener (8) is connected on the rocking bar (2), and the other end can be fixed on arbitrarily on the ground fixed station that can bear big pulling force.Need explanation, intermediate water cold grinding jar (1) is when the abrasive metal powder, and the Metal Ball of certain size is equipped with in the inside, and the collision of Metal Ball helps the abrasive metal powder.Need to prove,, need to fill a spot of inert gas toward intermediate water cold grinding jar (1) inside for preventing metal dust oxidation in process of lapping.

Owing to adopted such scheme, the purpose of this utility model is achieved.

Further specify the utility model below in conjunction with drawings and Examples.The utility model provides two accompanying drawings altogether.
