The effect of invention
Add man-hour carrying out shot-peening, in shot-peening Processing Room, utilize attracting mechanism to carry out attracting and forming subnormal ambient.By the wall configuring external gas suction port at shot-peening Processing Room, thus, extraneous gas is attracted (importing) in shot-peening Processing Room.The air-flow (being designated as below " outer gas stream ") extraneous gas suction port being configured in the extraneous gas making to attracted in shot-peening Processing Room to flow such position along the internal face of this shot-peening Processing Room, thereby, it is possible to prevent blasting materials and dust to be attached to the inwall (the first invention) of shot-peening Processing Room.Now, if due to the outside wall surface side configuring external air-flow rectification part of the described shot-peening Processing Room at described extraneous gas suction port, then outer gas stream is utilizing after this outer gas stream rectification part carries out rectification, attracted in shot-peening Processing Room by extraneous gas suction port, therefore, it is possible to efficiently extraneous gas to be attracted to (the second invention) in described shot-peening Processing Room.Described outer gas stream rectification part is the hollow form parts of both ends open, and one of opening surface is fixed on the outside wall surface of described shot-peening Processing Room, and is connected with described extraneous gas suction port (the 3rd invention).The cross section orthogonal with opening surface of described outer gas stream rectification part can be rectangle, is bent into the shape of L shape or く shape, bends to
any one (the 4th and the 5th invention) in the shape of shape.Further, by described outer gas stream guide member is configured in shot-peening Processing Room, thereby, it is possible to along wanting to prevent the wall of the attachment of blasting materials and dust from forming outer gas stream (the 6th invention) efficiently.Described outer gas stream guide member is set to tabular, preferably an end face of this plate is fixed on end face or the side wall surface of shot-peening Processing Room.If the longitudinal section of the described outer gas stream guide member orthogonal with the internal face of the described blasting apparatus being fixed with described outer gas stream guide member is set to rectangle, then in the making of shot-peening Processing Room very simple (the 7th invention).Further, also described longitudinal section can be bent into く shape or bend to
shape, to make outer gas stream efficiently along described internal face (the 8th invention).Now, the angle that preferred described extraneous gas guide member and the internal face of side of importing outer gas stream of the internal face being fixed with this extraneous gas guide member are formed is less than 90 ° (the 9th inventions).Although described extraneous gas introduction part can be configured to make outer gas stream along the internal face being configured with described extraneous gas suction port, also can be configured to make outer gas stream to form the internal face at right angle along with the internal face being configured with described extraneous gas suction port, but in order to make outer gas stream along the internal face flowing being configured with described extraneous gas suction port, described extraneous gas introduction part (the tenth invention) can be used rightly.
The extraneous gas be attracted, along with air-flow weakens away from described extraneous gas suction port, prevents the power of the attachment of blasting materials and dust from reducing.On the other hand, owing to producing towards the air-flow of attracting mechanism (being designated as below " internal gas flow ") in shot-peening Processing Room, therefore, by being configured in shot-peening Processing Room by described internal gas flow guide member, internal gas flow can be guided to internal face (the 11 invention).It is the tabular of rectangle that described internal gas flow guide member is set to such as tabular surface, the parallel both ends of the surface of this internal gas flow guide member are individually fixed in the side wall surface of shot-peening Processing Room, efficiently internal gas flow can be guided to internal face (the 12 invention) thus.Preferably the longitudinal section of the described outer gas stream guide member orthogonal relative to the internal face being fixed with described outer gas stream guide member is set to be bent into く shape or bend to
shape (the 13 invention).And, because described outer gas stream guide member and outer gas stream guide member are configured in the position apart from the described farther side of extraneous gas suction port discretely, thereby, it is possible to do not affect the target locations (the 14 invention) such as the flowing position of weakening internal gas flow being guided to the extraneous gas utilizing extraneous gas suction port to attract with attracting extraneous gas.And, for the distance of the inwall of described internal gas flow guide member and shot-peening Processing Room, by making the distance away from the end face side of described extraneous gas suction port narrower than the distance of the end face side near described extraneous gas suction port, the target locations (the 15 invention) such as the position that the flowing that internal gas flow can be guided to the extraneous gas utilizing extraneous gas suction port to attract thus weakens.
Particularly with the air sand blower of compressed air in the lump spray material, the compressed air (being designated as below " jet-stream wind ") sprayed from shot-peening working nozzle collides with the internal face of machined object or shot-peening Processing Room, and its part is towards end face direction (upper direction) reflection.Due to the air-flow produced because of reflection, the outer gas stream causing utilizing described extraneous gas suction port to attract, the internal gas flow utilizing described internal gas flow guide member to guide to internal face are obstructed because of reflected gas stream.Hindering parts by arranging adverse current, the situation (the 16 invention) be obstructed based on the outer gas stream of contrajet and the flowing of internal gas flow can be prevented.When described internal gas flow guide member is fixed on described shot-peening Processing Room, preferably described internal gas flow guide member (the 17 invention) is set in the position that the end face of the ratio of this internal gas flow guide member side far away apart from described extraneous gas suction port is farther.Increase owing to hindering the sectional area orthogonal with the direction away from described extraneous gas suction port of parts to be set to towards the direction of the described extraneous gas suction port away from described blasting apparatus described adverse current, thus, the situation hindering the outer gas stream of the setting of parts and internal gas flow to be obstructed based on this adverse current can not be there is.Especially, longitudinal section is preferably triangle (the 18 invention and the 19 invention)

Detailed description of the invention
For sand blasting unit, the example of accompanying drawing to the embodiment of the blasting apparatus in the present invention is used to be described.In addition, the present invention is not limited to the embodiment described in this description, can suitably change as required.In addition, in the following description, unless otherwise specified, all above lower left and right directions is described as the direction up and down (top side is set to upper direction) in figure.Further, unless otherwise specified, the internal face in so-called the present invention all represents end face in shot-peening Processing Room and side wall surface.
Blasting apparatus 1 comprises: shot-peening Processing Room 10, is configured with shot-peening processing nozzle 11 (being aspiration-type in the present embodiment) therein; And attracting mechanism 20 (being dust collect plant in the present embodiment), it links via the pipeline D be connected with the bottom of this shot-peening Processing Room 10, reclaims powder for generation of attraction.And be configured with separating mechanism 21 (being roto-sort device in the present embodiment), this separating mechanism 21 for isolating recycling blasting materials and the blasting materials that cannot recycle and dust from blasting materials and dust.
Compressed air supply source (not shown) is connected with via flexible pipe (not shown) at shot-peening processing nozzle.Blasting materials and the compressed air utilizing compressed air supply source to produce are sprayed to machined object W jointly, thus carries out the shot-peening processing of machined object.Blasting materials causes a part for this blasting materials broken or lack because of the collision with machined object W etc.Further, dust can be produced because causing the surface of machined object W to be ground with the collision of blasting materials.These blasting materials, dust dance in the air in shot-peening Processing Room, and described blasting materials, dust are attracted by the attraction produced by attracting mechanism 20, and are transferred to separating mechanism 21.The blasting materials and the dust that are transferred to separating mechanism 21 are classified into the blasting materials and dust (calomel mercurous chloride body) that cannot recycle because of broken or disappearance etc. and the blasting materials that can recycle (heavy powder), and the blasting materials that cannot recycle and dust are recovered by attracting mechanism 20.On the other hand, the blasting materials that can recycle is stored in blasting materials bank 22, again delivers to injection nozzle via flexible pipe H, again jointly sprays with compressed air, carries out shot-peening processing.(with reference to Fig. 1)
Owing to being attracted by attracting mechanism 20 in shot-peening Processing Room 10, be namely in subnormal ambient, therefore, by the wall configuring external gas suction port 12 at shot-peening Processing Room 10, extraneous gas is attracted (importing) in shot-peening Processing Room 10.Extraneous gas suction port 12 is configured to the internal face of flowing along shot-peening Processing Room 10 of the extraneous gas making to be attracted.Although blasting materials and dust because of produce from the injection of shot-peening processing nozzle 11 friction, with the reason such as attachment, molecular force, jog locking each other of the moisture in the collision of machined object W and the electrostatic charging, air and the compressed air that cause, oil content and be attached to the internal face of shot-peening Processing Room 10, but because the extraneous gas be attracted flows along internal face, therefore hinder the attachment of blasting materials and dust.In the internal face of shot-peening Processing Room 10, when wanting to prevent the attachment to end face 10a, described extraneous gas suction port 12 is configured at the upper position of side wall surface 10b, when wanting to prevent the attachment to side wall surface 10b, this side wall side in end face 10a arranges described extraneous gas suction port 12, also can combine this two kinds of ways.Further, preferred described extraneous gas suction port 12 relative to this extraneous gas suction port 12, this shot-peening Processing Room 10 outside wall surface side configuring external air-flow rectification part 12f (with reference to Fig. 3 (A)).Because the extraneous gas inwardly of the outside from shot-peening Processing Room 10 is rectified and flows in outer gas stream rectification part 12f, therefore, even if when the air-flow in shot-peening Processing Room 10 larger towards the vector of the outside of shot-peening Processing Room 10 near extraneous gas suction port 12, based on the extraneous gas after this rectification, also can not outflow and efficiently extraneous gas is attracted in shot-peening Processing Room 10.In addition, outer gas stream rectification part 12f is configured to the lateral direction from extraneous gas suction port 12 towards shot-peening Processing Room 10, and, as long as rectification can be carried out to the extraneous gas be attracted, the shape of described outer gas stream rectification part 12f, the angle formed with the wall of shot-peening Processing Room 10, size all without particular limitation of.Such as, as shown in Fig. 3 (B), outer gas stream rectification part 12f can not be made to form right angle relative to the wall of shot-peening Processing Room 10, but form the angle suitable arbitrarily of regulation, also can use the bending outer gas stream rectification part 12f of the fillet surface with radius R.And, as Fig. 3 (C) (Fig. 3 (C) is equivalent to the A-A line sectional view of Fig. 3 (A)), when multiple extraneous gas suction port 12 is configured on same line, can time each extraneous gas suction port 12 respectively configuring external air-flow rectification part 12f, also can cover the mode of all extraneous gas suction ports 12 to extraneous gas suction port 12 whole installation outer gas stream rectification part 12f.
Be provided with in shot-peening Processing Room 10 for guiding the outer gas stream guide member 13 being attracted to and wanting the extraneous gas preventing the internal face adhered to.Outer gas stream guide member 13 utilizes plate-shaped member to be formed, and end face 10a or the side wall surface 10b (with reference to Fig. 4 (A)) of blasting apparatus 10 are fixed in its one end.The longitudinal section orthogonal with the internal face being fixed with this outer gas stream guide member 13 can be rectangle, be bent into the shape of く shape, bend to "
" shape shape in any one.Now, the differences in angle θ that preferably this outer gas stream guide member 13 and the internal face of importing outer gas stream side of the internal face being fixed with this outer gas stream guide member 13 are formed is less than 90 °.If θ is more than 90 °, then the amount of the outer gas stream flowed along the internal face of shot-peening Processing Room 10 reduces, and hinders the power of the attachment of described injecting-unit and dust to weaken (with reference to Fig. 4 (B)).And, for outer gas stream guide member 13, as shown in Fig. 5 (A), one end can be fixed on the internal face orthogonal with the internal face being configured with described extraneous gas suction port, also as shown in Fig. 5 (B), one end can be fixed on the internal face being configured with described extraneous gas suction port.The former can change the flow direction of the extraneous gas be attracted, and the latter can carry out rectification, forms the air-flow leaving internal face after attracteding in shot-peening Processing Room 10 at once to avoid extraneous gas.And, outer gas stream guide member 13, when being provided with multiple described extraneous gas suction port 12, according to the difference of object, one end of outer gas stream guide member 13 can be fixed on the internal face orthogonal with the internal face being configured with described extraneous gas suction port 12, also can be fixed on the internal face that is configured with described extraneous gas suction port 12 or combine above-mentioned situation (Fig. 5 (C)).And, when not needing to configure described outer gas stream guide member 13 to all described extraneous gas suction ports 12, also only outer gas stream guide member 13 (Fig. 5 (D)) can be set to a part described extraneous gas suction port 12.
Although extraneous gas air-flow after being attracted by extraneous gas suction port 12 is strengthened at once, hinder blasting materials and dust to the internal face of shot-peening Processing Room 10 adhere to effective, but along with away from extraneous gas suction port 12, the flowing of extraneous gas weakens, then hinder the effect of described attachment to weaken.Produce towards the air-flow (internal gas flow) of the bottom of shot-peening Processing Room 10, i.e. attracting mechanism (in addition in shot-peening Processing Room 10, the concept of the internal gas flow in this description so-called is as follows: represent that the compressed air (jet-stream wind) jointly sprayed by shot-peening processing nozzle 11 and blasting materials collides with machined object W and internal face and reflects, with its part upward to, afterwards towards the air-flow of the bottom linked with attracting mechanism 20 be main body, shot-peening Processing Room produce, air-flow except the outer gas stream just imported).Guide internal gas flow by the position of weakening to the flowing of described outer gas stream, described attachment can be hindered.Position for weakening to the flowing of described outer gas stream guides the internal gas flow guide member 14 of internal gas flow to be configured in shot-peening Processing Room 10.Internal gas flow guide member 14 uses the plate-shaped member (being such as bent into 135 ° ~ 170 °) (with reference to Fig. 6 (A)) being bent into く shape.Described internal gas flow guide member 14 is configured in relative to the position of extraneous gas suction port 12 away from described outer gas stream guide member 13.Further, the distance between the internal face of internal gas flow guide member 14 and shot-peening Processing Room 10 is configured to, and the distance away from the end face side of extraneous gas suction port 12 is narrower than the distance of the end face side of close extraneous gas suction port 12.Namely, when being configured with outer gas stream guide member 13 and internal gas flow guide member 14 as shown in Figure 6, the distance be configured with between the side of extraneous gas suction port 12 and internal gas flow guide member 14 is configured to, away from the side of extraneous gas suction port 12 that is the distance of below than the side of close extraneous gas suction port 12 that is the distance of top little.This distance can be narrow continuously, also can be the part (with reference to Fig. 6 (A) and Fig. 6 (B)) in a part for described internal gas flow guide member 14 with the identical distance of connection.For described internal gas flow guide member 14, except described shape, bend to
the plate-shaped member of shape (with reference to Fig. 6 (C)), not bend and any one in unbending rectangular plate member (with reference to Fig. 6 (D)) can both be applied.
And, because a part for the air-flow of described reflection flows near side wall surface 10b and its, therefore, to be imported by extraneous gas suction port 12 or the outer gas stream that flows downward along side wall surface 10b by means of outer gas stream guide member and the internal gas flow that flows downward along side wall surface 10b by means of internal gas flow guide portion are obstructed because of the air-flow of described reflection (with reference to Fig. 7).In order to prevent this situation, parts 15 adverse current are hindered to be configured at the side wall surface 10b of shot-peening Processing Room 10.Described adverse current hinder parts 15 be set to its upper end than described internal gas flow guide member 14 bottom more on the lower.Preferred described adverse current hinders parts 15, and along with trend below, the sectional area of horizontal direction increases continuously, and to avoid because arranging that this adverse current hinders parts 15, the flowing of the outer gas stream that flows downward described in causing and internal gas flow is obstructed.Longitudinal section is triangle (with reference to Fig. 8 (A)), 1/4 circle (with reference to Fig. 8 (B)), 1/4 ellipse (with reference to Fig. 8 (C)), oval part distortion, and upper end is that in 1/4 ellipse (with reference to Fig. 8 (D)) of acute angle etc., any one can both suitably use.
