Description

Technical Field [0001] The present invention relates to a sandblasting device for obtaining a precise surface,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sandblasting machine and corresponds to a technical field for machining a surface of a workpiece.

Generally, a blast machine (Blast M / C) is a machine for machining a surface of a product. More specifically, it is a machine for casting abrasive (shot ball or sand) on the surface of a workpiece such as cast steel and cast products, To remove the same foreign matter or to remove the oxide layer.

Such a blast machine is also a pretreatment process such as painting and coloring of a workpiece, and the surface of the workpiece is processed so that the post-treatment process is convenient for smoothly processing the surface.

The blasting machine includes a hanger type which rotates a workpiece on a hanger according to the shape and size of the workpiece and sprays an abrasive material, a table type which places the workpiece on a rotating table and a conveyor And a tunnel type having a conveying means such as a conveying mechanism.

The method of spraying an abrasive according to the type of abrasive used in a blasting machine is largely classified into a method in which particles of a metal such as a shot or grit are used as an abrasive, ) Is impinged on the impeller which rotates at a high speed, and there is an impeller-type shot blast method.

Sand blast method in which sand (sand) is used as an abrasive material and sprayed with a nozzle by using compressed air, a direct pressure type in which the compressed air is applied to the tank containing the sand, And the suction pipe is connected to the suction pipe through which the compressed air flows by the pressure difference.

As shown in Fig. 1, in order to process the surfaces of small-sized machine parts and the like, apron type blast machines mainly for injecting a workpiece into a machine body and projecting an abrasive material thereon are mainly used.

The endless belt 8 is mounted on a plurality of guide rollers 5 and the guide rollers 6 are mounted on both ends of the endless belt 8 so that the workpiece 4 is put on the upper surface of the endless belt 8 2 are formed.

A plurality of workpieces 4 are put into the projecting body 2 by projecting an abrasive material projecting device 7 on an upper part of the projecting body 2 and the abrasive material 3 is projected onto the workpiece 4, So that the endless belt 8 is driven by the guide roller 6 and the guide roller 5 so that the workpiece 4 is moved inwardly The workpiece is turned upside down and the workpieces located at the upper and lower portions are mixed, so that the processed workpiece is uniformly processed.

On the other hand, the abrasive material projecting device 7 is an impeller-type shot blast. It is generally provided with an impeller having a plurality of blades for rotating, a motor for rotating the blades, and a supply hopper for supplying abrasives (shot)

To solve the problem.

Preferably, the blast portion includes a first blast 210 and a second blast 220. The first blast 210 is coupled to an upper portion of a second support 120 that can move up and down, The second support 220 is mounted on the third support 130 on the side of the first blast 210 and the second blast 220 is coupled to the tip of the third support 130. [

In addition, the second support base 120 is made to be pneumatically operated so that the upper end of the first support base 110 can be moved along the center axis.

More preferably, the first support 110 supporting the blast portion can reciprocate left and right through a ball screw in the longitudinal direction of the sand machine by a drive motor 620 on one surface of the transfer chamber 100 So as to be able to move left and right.

In addition, the cradle includes a fixed cradle 300 and a moving cradle 310, and the moving cradle 310 is configured to be movable up and down.

More preferably, the blast portion includes a sanding nozzle 221, and the blast portion is configured to adjust the angle up and down.

The second support base 120 is configured to act on the motor so as to stop the operation of the second support base 120 so that the second support base 120 is not moved any more through the position sensing control sensor 500 when the blast is moved to the lowermost position do.

In addition, when the ball screw is moved by the motor 620 to the rightmost position, the first support base 110 stops the motor 620 so that the first limit switch 510 can not move to the right by the first limit switch 510 do.

Preferably, when the ball screw is moved by the motor 620 to the leftmost position, the first support 110 stops the motor 620 so that it can no longer move to the left by the second limit switch (not shown) .

In addition, the transfer device of the blast part constitutes a motor 620 and a ball screw which moves by the motor.

More preferably, the sand machining apparatus forms a transparent window so that the inside of the sand mill can be seen so that the operator can see the cast 700 during operation.

There is an effect that the workpiece moves and the blast part moves so that the workpiece obtains a more elaborate surface.
