Technical field

The present invention relates to the manufacture method of a kind of elastic grinding material and manufacture device and blasting method and sand blasting unit, more Body ground, relates to the manufacture method of a kind of elastic grinding material with the structure that abrasive particle is attached on the surface of resilient nucleus and implements to be somebody's turn to do The device of method and as the reuse method of elastic grinding material or the manufacture method including elastic grinding material in composition of device Or manufacture the circulating blasting method of device and circulating sand blasting unit.

It is pointed out that " manufacture " of resilient abrasive of the present invention includes being attached to abrasive particle original nucleome On surface, and (include it by abrasive particle (again) being attached to the nucleome of the elastic grinding material through using abrasive particle to remove from surface Remain the nucleome of abrasive particle) surface on " recycling ".

Background technology

Have been presented for having such as by entering abrasive particle in resilient nucleus or is attached to the table of resilient nucleus by mixing for abrasive particle Carry on face the nucleome of abrasive particle various elastic grinding materials (Japan Patent No.2,957,492, Japanese Patent Laid-Open No.2001- 207160, Japanese Utility Model JP No.S55-98565), and by using the sandblasting of this elastic grinding material, by with work The impact that the collision of part causes is absorbed due to the elasticity of nucleome.Therefore, workpiece such as can polished, remove oxygen While changing the process such as film and deburring, decrease what the satin face formed on the surface of workpiece caused by general sandblasting processed Surface.

Especially, using suppression shock resistance to prevent in the elastic grinding material of nucleome shunk back in an impact, passing through The elastic grinding material making injection slides the mirror finish that can also carry out can not carrying out in commercial blast on the surface of workpiece, This purposes (Japanese Patent Laid-Open No.2006-159402) going far towards to widen sandblasting.

The structure of this elastic grinding material can include by mixing for abrasive particle enter by the nucleome that such as rubber elastomeric material is constituted In so that nucleome carries the structure (with reference to UM ' 8565) of abrasive particle, such as has the Plant fiber of adhesiveness in oily and sugared composition As the structure (Pat ' 7492) of nucleome or depend on that water content is to play adhesiveness and elastic gel is used as the structure of nucleome The structure that abrasive particle is attached on the surface of nucleome by (' 7160) etc..

Especially, in order to manufacture the elastic grinding material with the structure being attached on the surface of nucleome by abrasive particle, at nucleome it is When all Plant fiber and gels etc. in oil and sugar composition described above with adhesiveness play self-sticking nucleome or Such as polyurethane etc. does not have self-sticking resin be used as in the case of nucleome by being coated with core with binding agent or sticker During body, nucleome and abrasive particle it is concomitantly introduced into rotary drum and stirs, so that the surface of abrasive particle contact nucleome, then passing through centrifugal action Collided by the nucleome contacted with abrasive particle, rubbing and being pressed on bulging inwall and other nucleomes makes abrasive particle securely and high density Be attached on the surface of nucleome.This method is also used for recycling the elasticity with the surface through using abrasive particle to come off from it Abrasive material.

Including by playing adhesiveness and the elastic grinding material of elastic nucleome containing water in using above-mentioned elastic grinding material In the case of, in view of over time according to the machining state caused by being dried the elasticity of nucleome and the change of adhesiveness that cause Change, it is also proposed that, just reclaimed at abrasive material once spray and by the circulating sand blasting unit of its fill-before-fire, can be passed through (Japan Patent is special to regulate the water content of elastic grinding material to arrange the liquid supplying apparatus of water spray in the blood circulation of elastic grinding material Open No.2009-125818).

Therefore, as shown in Figure 10, in the case of circulating sand blasting unit carries out the sandblasting of use elastic grinding material, elastic The cutting ability of abrasive material is gradually reduced in time, and at the machining state of the workpiece processed by new elastic grinding material with pass through The such as surface such as glossiness and minute surface degree is there is between the machining state of the workpiece that the elastic grinding material that use was reused processes The bigger difference of state.

Even if elastic grinding material being replaced by new abrasive material at regular intervals to prevent the change of machining state, cutting output is also The most temporarily increase, but, cutting output reduces in time, and as shown in Figure 10, cutting output changes astatically, Therefore workpiece still can not be processed with the quality of certain level.

Thus, sandblasting is carried out at the elastic grinding material by use with the structure being attached on the surface of nucleome by abrasive particle In the case of, it is necessary to use batch processing or when using every time after recycling is several times by replacing elastic grinding material The elastic grinding material the most more renewed.Accordingly, there exist the problem that productivity ratio is substantially reduced, all interrupt because change every time Sandblasting.

As ' described in 5818, in order to make use include having the elasticity changed according to the change of water content and Machining state in the sandblasting of the elastic grinding material of the nucleome of adhesiveness is uniform, propose by arrange in circulating sand blasting unit to The liquid supplying unit of water spray in the blood circulation of abrasive material, even if in the case of recycling elastic grinding material, being also prevented from bullet Property being dried of abrasive material and the change of machining state that causes.Also relevant to the abrasive particle that the surface from nucleome comes off, if can be The blood circulation of abrasive material recycles elastic grinding material similarly, then just can not be carried out continuously sandblasting to interrupt processing.

But, by as above elastic grinding material to be recycled being concomitantly introduced in rotary drum with abrasive particle and stirs and then leads to Cross the nucleome that collision, friction and the centrifugal force produced in stirring exposes not only by new abrasive particle is attached to Grain Falling Off On, and by new abrasive particle being pressed and being fixed on the surface of nucleome to high-density and be firmly attached abrasive particle, thus Recycling has the elastic grinding material of the nucleome that abrasive particle comes off from it.Therefore, it is not possible to simply by sand blasting unit The elastic grinding material water spray of circulation recycles elastic grinding material.

On the other hand, owing to the cydariform of above-mentioned elastic grinding material manufactures plant bulk greatly, so at this device with circulating In the case of sand blasting unit combines, the structure of device is increasing.Additionally, due to cydariform manufactures the profit again of device resilient abrasive Carrying out with batch methode, even if so manufacturing device and being combined with circulating sand blasting unit, sand blasting unit the most also must stop again Utilize elastic grinding material.

In order to nucleome is so combined with abrasive particle, mixed cell 11 the solid and gas two-phase flow produced is introduced by having at least More than one tortuous spaces 121,122 and 123 pipeline composition combining unit 12 in, and via by tortuous spaces 121, 122 and 123, abrasive particle is pressed by propulsive force and/or centrifugal force by solid and gas two-phase flow towards the surface of the nucleome reclaiming abrasive material.

For this tortuous spaces as shown in Figure 4 A as an example, the such as combining unit 12 formed by SUS pipe etc. A part can bend to right angle to form tortuous spaces 121, so that the recovery abrasive material kept straight in combining unit 12 exists At tortuous spaces 121, the inwall with combining unit 12 collides so that abrasive particle is by pressing to nucleome.

In the case of forming tortuous spaces in this mode by making combining unit 12 bend linearly, angle of bend It is not limited to right angle as shown in the accompanying drawings, and it can bend with the angle more than or less than right angle.Although it is it addition, shown The example gone out shows the situation giving right-angle bending part 121 and 121 at two parts to form square C-shape, But combining unit 12 is not limited to this example, and can only have one or more tortuous spaces.

Additionally, tortuous spaces can bend as shown in Fig. 4 B or Fig. 4 C, and curved shape is being set by this way In the case of tortuous spaces 122 or 123, such as, pressed by centrifugal force by the recovery abrasive material of tortuous spaces 122 and 123 Rotate while the outer circumferential side of the inwall being pressed onto combining unit 12, to be made by the propulsive force of solid and gas two-phase flow and/or centrifugal force Abrasive particle is pressed on nucleome securely.

It addition, in the case of the tortuous spaces arranging this curve, it can be sequentially formed as circular or spiral type.

It addition, in the case of the tortuous spaces with curved shape is set, as shown in Figure 4 C, the Curved of tortuous spaces Shape changes (that is, curvature increase) the most sharp along with extending to downstream from upstream side.

Owing to colliding by the abrasive material that reclaims of tortuous spaces with the inwall of combining unit 12 or contacting, thus along with it moves To downstream, its translational speed is gradually lowered, and acts on the centrifugal force reclaimed on abrasive material and is gradually lowered.

But, the centrifugal force being in swing-around trajectory on the object of movement due to effect and the distance away from center of rotation axle (radius) and angular velocity square the proportional change of product, it is possible to the centrifugal force that suppression is applied to reclaim on abrasive material Decline and enable to according to along with the decline of translational speed reclaiming abrasive material declined close to downstream, by increase along with Extend to the change of the curve (curvature) in downstream and for a long time abrasive particle is pressed on nucleome, such as spiral-shaped by being formed Increase the angular velocity reclaiming abrasive material.

In order to obtain, abrasive particle is attached on the nucleome of arbitrary structures required thrust, form linear tortuous spaces In the case of, the quantity in the space that regulation is formed, in the case of forming curves tortuous spaces, the total length of regulation tortuous spaces (quantity of spiral) etc..

By this way, while abrasive particle is by the tortuous spaces of combining unit 12, it is pressed into the core of recovery abrasive material On body, to obtain by abrasive particle to high-density and is firmly adhered on the nucleome reclaiming abrasive material that abrasive particle comes off from it The recycling elastic grinding material of recycling.

Therefore, the recycling elastic grinding material obtained by this way is brought back at an arbitrary position the circulation of elastic grinding material In system, thus continuously or periodically recycle (off and on) 10-50% of the elastic grinding material circulated in blood circulation.Cause Even if this is in the case of the long-time elastic grinding material of injection continuously, in blood circulation, the elastic grinding material of circulation can also always be tieed up Hold in particular state to maintain machining state consistently.
