Description

  The present invention relates to a shot blasting apparatus using a projector using an impeller for removing deburring and surface treatment of a molded product, dirt on the surface of a workpiece, and the like.

  Conventionally, this type of shot blasting apparatus uses a projector using a metal impeller.

For this reason, in addition to the disadvantage that the projection material is damaged by the collision of the projection material with the impeller at the time of projection, the impeller is damaged if a projection material with high grindability is used, and therefore cannot be used. There was a drawback.
nothing special

  In view of the conventional drawbacks as described above, the present invention can improve the durability without damaging the impeller and the projection material, and can be used for a projection material with high grindability or a light projection material with a fine particle specific gravity. An object of the present invention is to provide a shot blasting apparatus that can be used in any state such as ultra-low temperature, room temperature, and wet.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.

In order to achieve the above object, according to the present invention, in a shot blasting apparatus using a projector using an impeller, the shot blasting apparatus is configured by using the impeller formed of high wear-resistant rubber.

  As is clear from the above description, the present invention has the following effects.

(1) In a shot blasting apparatus using a projector using an impeller, since the shot blasting apparatus is configured by using the impeller formed of high wear-resistant rubber, the projection material collides with the impeller during projection. Even so, it can be prevented from being damaged.
Therefore, the durability of the projection material can be improved and the cost can be reduced.

(2) According to the above (1), it is possible to reduce noise generated when the projection material collides with the impeller.

(3) According to the above (1), the impeller can be used without damage even if a projection material with high grindability is used.
Therefore, the selection range of a projection material spreads and it can use widely for various operations.

(4) According to (1), the impeller can be made lightweight, so that high-speed rotation can be achieved.
Therefore, while being able to project a projection material efficiently, the use of a projection material with fine particles and light specific gravity can be used.

(5) In claim 2, the same effects as in the above (1) to (3) can be obtained.

(6) In claim 3, the same effects as in the above (1) to (4) can be obtained, and the liquid in which the projection material is mixed is projected at a wide angle by a projector using an impeller to deburr the molded product. It is possible to remove dirt on the surface of the workpiece or surface treatment or workpiece.

(7) According to the above (5), since the liquid mixed with the projection material is supplied to the projector using the impeller by the pump, the structure is simple and the liquid mixed with the projection material can be transported smoothly.

(8) According to the above (5), the liquid in which the projection material is mixed by the pump is supplied to the projector using the impeller, and the projection is projected so that burrs and the like of the molded product can be removed to the workpiece. It is not necessary to transport the liquid mixed with the blasting material to the machine at an increased speed or pressure, and a structure that is simple and reliably transports can be used.

(9) Claim 4 can obtain the same effects as in the above (1) to (7), the structure of the projector is simple and can be easily manufactured, and the slurry pump is used efficiently. The liquid which mixed the projection material excellent in durability can be supplied.

  Hereinafter, the present invention will be described in detail from the best mode for carrying out the present invention shown in the drawings.

  1 to FIG. 7, in the first preferred embodiment for carrying out the present invention, reference numeral 1 denotes a shot blasting apparatus according to the present invention for removing deburring and surface treatment of a molded product, dirt on the surface of a workpiece, and the like. The shot blasting apparatus 1 includes a case body 2, a table 4 formed of a perforated plate or a net body as a support for supporting the work 3 provided in the upper portion of the case body 2, and the table 4 A sorter using an open / close door 5 attached to the case body 2 and a vibrating screen provided in the case body 2 below the table 4 via a hopper 6 so that the workpiece 3 can be taken in and out. 7, a liquid tank 8 for storing liquid such as water and cleaning liquid selected by the sorting device 7, a projection material tank 9 for storing projection material, a small garbage tank 10 for storing small garbage, and a large garbage container for storing large garbage. A tank 11, a mixing tank 13 including a mixer 12 that guides and mixes the liquid from the liquid tank 8 and the projection material from the projection material tank 9, and the projection material to the table 4 above the case body 2. The projector 15 using the impeller 14 formed of high wear-resistant rubber attached so that the mixed liquid can be projected, and the liquid in which the projecting material of the mixing tank 13 is mixed are sucked, and the inside of the projector 15 Shower device provided with a supply passage 18 in which a slurry pump 17 leading to a nozzle 16 located at a position is provided, a pump 19 for showering the liquid in the liquid tank 8 onto the work 3 supported by the table 4, and a shower nozzle 20 21.

  The projector 15 has a lower surface opened 22 and a wheel cover 23 in which a nozzle insertion hole 24 into which the nozzle 16 is inserted and fixed is formed on a suction side wall surface 23a. The projector 15 is rotatably mounted in the wheel cover 23. The impeller 14 made of high wear-resistant rubber and a high-speed motor 25 attached to the wheel cover 23 so that the impeller 14 is driven to rotate at a high speed. The impeller 14 is a drive shaft of the high-speed motor 25. 26, one disk-shaped side plate 27 attached to 26, and a plurality of vane plates 28 that are radially fixed to a portion excluding the central portion of the one side plate 27, and the reciprocating vane plates 28 are covered. And the other side plate 30 having a nozzle insertion hole 29 at a portion corresponding to the nozzle insertion hole 24 of the wheel cover 23. .

The shot blasting apparatus 1 configured as described above uses water as a liquid when removing burrs from a molded product, and uses cleaning water when removing dirt on the workpiece surface.
When blasting, the work 3 is supported on the table 4 and the projector 15, the pump 19, the slurry pump 17 and the sorting device 7 are driven, so that the liquid mixed with the projection material in the mixing tank 13 is slurry pump. 17 is passed through the supply passage 18 and ejected from the nozzle 16. The liquid containing the projection material ejected from the nozzle 16 is projected toward the workpiece 3 on the table 4 by the impeller 14 formed of high wear-resistant rubber rotating at a high speed of the projector 15 to perform blasting. Do.
For this reason, since the liquid projection material including the projection material colliding with the impeller 14 rotating at high speed collides with the impeller 14 made of high wear-resistant rubber, it is efficiently damaged like a conventional metal-made impeller. In addition to being able to block, the projection from the impeller 14 can be performed in the same manner as a metal-made impeller.
The liquid mixed with the projection material projected by the projector 15 is supplied to the sorting device 7 through the hopper 6 together with the material removed by the workpiece, and sorted into large dust, projection material, small dust, and liquid. To the large garbage tank 11, the projection material tank 9, the small garbage tank 10 and the liquid tank 8.
The liquid supplied to the liquid tank 8 is supplied to the shower nozzle 20 by the pump 19 of the mixing tank 13 and the shower device 21 and is showered on the work 3 on the table 4.
Thus, the liquid mixed with the projection material and the liquid to be showered are circulated and used for the blasting process.
