Description

Shot blasting device

The present invention relates to a large shot blasting apparatus for performing deburring of a large amount of a large amount of processed material.

The conventional shot blasting apparatus is used in the case of removing fine burrs attached to a small molded product.

However, recently, there is a demand for removing the burr attached to a large molded product, and as a countermeasure, the size of the cylindrical body is increased (from about 10 kg in the past to about 26 kg), and the projection material and the projector are increased in size. In response to such a countermeasure, there is a disadvantage in that the processed material that cannot project the projection material into the enlarged cylinder in an efficient manner is expensive, and the projector is provided with a large size. .

In the eleventh, the large-sized processed object 12 is housed in a cylindrical shape having a small diameter in the upper and lower portions of the octagonal shape, and is disposed in an inclined state. The cylindrical body driving device 15 having the motor 14 is used by the cylindrical body driving device 15 The large cylindrical body 13 is rotationally driven and attached to the outside of the opening and closing cover 8; the impeller insertion hole of the inclined surface member 16 which is disposed obliquely and offset with respect to the cylindrical body 13 on the upper front surface of the cover case 5 17, 17; projectors 19, 19, the projectors 19, 19 are mounted to the inclined surface member 16, and The wheels 18 and 18 are located in the impeller insertion holes 17 and 17 and the hopper 21. The hopper 21 is housed in the casing 5, and is located at a lower position of the cylindrical body 13, so that burrs and projections from the cylindrical body 13 can be projected. The material 20 is guided downward; a sorting device 22 is installed at a lower position of the hopper 21 to sort large burrs, projection materials, and small burrs from the hopper 21; and the sorting device 22 is housed. a large burr storage container 23 for sorting large burrs; a projection material storage tank 25 capable of projecting the projection material 20 sorted by the sorting device 22 through the suction hoses 24, 24 Guided by the machines 19 and 19; a small burr storage container 26 that houses the small burrs sorted by the sorting device 22; and a refrigerant supply device 28 having a refrigerant supply into the cover box 5 Open and close the valve 27.

Further, the impeller insertion holes 17 and 17 which are disposed obliquely and offset with respect to the cylindrical body 13 are disposed, and two projectors 19 and 19 are provided because the cylindrical body 13 rotates counterclockwise. Then, the processed object 12 is moved to the right side of the lower position of the cylindrical body 13, so that the projection material can be reliably projected onto the processed object 12 located at the lower position of the cylindrical body 13 and moved to the right side of the cylindrical body 13 by the gravity downward position. The workpiece 12 is processed and can be widely projected in the axial direction of the cylindrical body 13 (the front-rear direction of the cylindrical body 13).

The large-sized cylindrical body 13 has an octagonal shape, and is attached with an octagonal cylindrical tubular body 30 having a plurality of holes 29 formed with a small diameter in the upper and lower portions; covering the bottom surface of the cylindrical body 30 and forming a bottom plate 31 having a conical or truncated cone shape projecting inwardly of the central portion; and a stirring plate 36 comprising: a substantially triangular agitating plate main body 33, a returning plate 34, and a cylindrical body 30 at the returning plate 34 The fall prevention portion 35 formed by bending the distal end portion of the input port 32 side is fixed to the inner wall surface of the cylindrical body 30 with the inclination 33c, and the bottom surface side of the cylindrical body 30 is provided.

In the shot blasting apparatus 1 of the above configuration, the opening and closing cover 8 is opened from the opening 4 of the cover box 5, and the cylindrical body 13 is positioned outside the cover box 5.

In this state, the large-sized processed material 12 to be deburred is put into the cylindrical body 13, and the opening and closing cover 8 is pressed in the direction of the cover box 5, and the opening 4 of the cover case 5 is closed by the opening and closing cover 8.

Then, the opening and closing valve 27 of the refrigerant supply device 28 is opened as needed, and the inside of the casing 5 is cooled by the refrigerant.

Next, the cylinder driving device 15 is driven to rotate the cylinder 13 and drive the projectors 20, 20 to rotate the impellers 18, 18 due to the driving of the projectors 20, 20, thereby The projection material 20 in the projection material storage tank 25 is attracted by the suction hoses 24, 24 and projected onto the treatment 12 in the cylinder 13.

At this time, the impellers 18 and 18 of the projectors 19 and 19 are inclined with respect to the cylindrical body 13 and are arranged in a staggered manner. Therefore, in the front-rear direction (the direction of the insertion opening 32 of the tubular body 13 and the bottom plate 31, that is, the axial direction of the cylindrical body 13 On the other hand, the projection material 20 is widely projected, and the projection material 20 is projected on the front and rear portions of the movement of the workpiece 12 in the cylindrical body 13, so that the burr can be efficiently removed.
