Description

Shot blasting device

Technical Field

The present invention relates to a large-sized blasting device used when a large-sized object to be deburred is processed.

Background

The conventional shot blasting device is used for removing fine burrs attached to a relatively small molded product, but recently, there is an increasing demand for products capable of removing burrs attached to a relatively large molded product, and the size of a cylinder, a projection material, a projector, and the like is increasing.

Even in such a product having a large-sized cylinder, the height of the casing itself is limited to some extent in consideration of the entrance and exit of the processed object, and therefore, the hopper at the lower portion of the cylinder is formed into a gentle slope to maximize the capacity of the blasting chamber inside the casing, thereby allowing the large-capacity cylinder to be accommodated.

However, when the hopper is formed to have a gentle slope in order to maximize the capacity of the blasting chamber while limiting the height of the box body, there is a disadvantage that the shot material cannot be efficiently recovered, and the like, and even the blasting device cannot be efficiently driven.

Disclosure of Invention

Problems to be solved by the invention

In view of the above-described conventional drawbacks, an object of the present invention is to provide a blasting device capable of efficiently collecting and processing a shot material of a blasting device mounted with a large-sized cylinder.

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

However, the drawings are only for explanation and do not limit the technical scope of the present invention.

Means for solving the problems

In order to achieve the above object, the shot blasting apparatus of the present invention comprises: a box body, which is provided with a shot blasting processing chamber; an opening/closing door that opens and closes the box body; a cylinder rotatably and obliquely attached to the housing; a cylinder driving device which drives the cylinder to rotate and is installed to the cylinder support frame; the hopper is arranged at the lower part of the shot blasting processing chamber of the box body; a screening device which is connected with the lower part of the hopper and screens burrs and projection materials falling from the hopper; and a vibrating device which is in contact with both the hopper and the screening device and can vibrate the hopper and the screening device simultaneously.

Effects of the invention

As is apparent from the above description, the present invention can obtain the following effects.

(1) In the invention according to claim 1, since the vibrating device that can vibrate the hopper and the screening device is attached, the shots, burrs, and the like can be efficiently collected.

(2) Even if the hopper is a gentle slope, the projection material, burrs, and the like can be reliably collected by the vibration device.

Therefore, even if a large-sized cylinder is used, the blasting chamber can be designed to be compact.

(3) Since the shots, burrs, and the like can be reliably collected by the vibrating device, the shots and the like remaining on the gentle slope of the hopper can be blown off without introducing air or the like, and the temperature of the shot blasting chamber can be maintained at a predetermined temperature.

(4) The invention according to claim 2 can also obtain the same effects as those in the above-described items (1) to (3), and can set the temperature at the time of shot blasting to a low temperature.

Further, when the large cylinder 10 is rotated counterclockwise, the processed object 13 moves to the right side of the lower position of the large cylinder 10, and therefore, the two

projectors

16 and 16 provided on the upper surface of the outer wall of the front portion of the casing 5 in an inclined and staggered state are provided so that the projected materials can be projected accurately and widely in the axial direction of the large cylinder 10 (the front-rear direction of the large cylinder 10) onto the processed object 13 at the lower position of the large cylinder 10 and the processed object 13 moving to the right side of the large cylinder 10 and falling to the lower position by gravity.

The large-sized cylinder 10 is octagonal, and includes: an octagonal cylindrical body 27, the upper and lower parts of the cylindrical body 27 having a small diameter, the cylindrical body 27 having a plurality of holes 24 formed therein, the cylindrical body 27 lacking a lower wall 25 and a central arm 26 on one side; slide rails 28, the slide rails 28, 28 being formed at the ends of the lower walls 25, 25 of the portions of the lower wall 25 and the central arm 26 lacking one side of the cylinder main body 27; an opening/closing cover 12 provided with a handle 29, the opening/closing cover 12 being engaged with the slide rails 28, 28 and composed of a lower wall 25a formed with a plurality of holes 24 and sliding upward and a central arm 26 a; a locking piece 29a for keeping the closing state of the opening and closing cover 12; a bottom plate 30 formed in a conical shape, a truncated conical shape, a polygonal conical shape, or a polygonal truncated conical shape, with a central portion protruding inward, so that the bottom plate 30 covers the bottom surface of the cylindrical body 27; and an agitation plate 35, the agitation plate 35 being constituted by an agitation plate main body 32, a return plate 33, and a drop-off prevention portion 34, the agitation plate main body 32 being substantially triangular and fixed to an inner wall surface of the cylindrical body 27 in an inclined state 32c, the inclined state 32c being a state in which a rear end portion 32b of the agitation plate main body 32 on the bottom surface side of the cylindrical body 27 is positioned forward in the rotation direction than a tip portion 32a of the introduction port 31 side, the return plate 33 being formed at the tip portion 32a of the agitation plate main body 32 except for a portion on the rear end portion 32b side and guiding the processed object 13 loaded on the agitation plate main body 32 in the bottom surface direction of the cylindrical body 27, and the drop-off prevention portion 34 being formed by bending at the tip portion of the return plate 33 on the introduction port 31 side of the cylindrical body 27.

Further, a locking piece 36 is attached to the case 5 and the opening/closing door 7, and the locking piece 36 maintains a closed state of the opening/closing door 7 that closes the opening 2 of the case 5. The locking member 36 may have any conventional structure as long as it can easily lock and unlock.

A method of using the blasting apparatus 1 configured as described above is described, in which after the large-sized cylinder 10 is positioned outside the casing 5, the large-sized processed product 13 from which burrs are to be removed is put into the large-sized cylinder 10.

Next, when the opening/closing door 7 is pushed in the direction of the box 5, the opening/closing door 7 and the tubular body support frame 9 slide along the outer fixed rail 6 and the inner fixed rails 8, and after the opening/closing door 7 covers the opening 2 of the box 5, the opening/closing door 7 is locked to the box 5 by the locking piece 36.

Then, the cylinder driving device is driven by driving the motor 37 attached to the opening/closing door 7 of the cylinder driving device, and the large cylinder 10 is rotated.

Further, the

impellers

15, 15 are rotated by driving the two projectors 16, the shots 14 in the shot storage tank 21 are sucked by the suction hoses 20, and the shots 14 are projected onto the processed object 13 in the large cylinder 10 by the

impellers

15, 15.

When the cooling burrs are easily removed when the

projectors

16 and 16 are driven, the on-off valve 38 of the coolant supply device 23 is opened to supply the coolant into the shot peening chamber 3.

When the shots 14 are projected, the projected shots 14, burrs, and the like fall down onto the hopper 17. The dropped shots 14 and the like are partially left on the hopper 17 without being conveyed to the screening device 18, but the remaining shots 14a and the like are also conveyed to the screening device 18 by the vibration by driving the vibration device 42. The hopper 17 is provided at the lower part of the blasting chamber 3 with an elastic member 41 such as rubber or synthetic resin interposed therebetween, and the elastic member 41 prevents the shots 14 and the like from falling out of the gap between the blasting chamber 3 and the hopper 17. Further, the elastic member 41 can prevent the vibration of the vibration device 42 from being transmitted to the blasting chamber 3, and the hopper 17 and the like can be efficiently vibrated.

Further, since the screening device 18 is provided in connection with the hopper 17, the screening work can be performed more efficiently by vibrating the hopper by the vibrating device 42. The shots 14 thus screened are accumulated in a shot storage tank 21 and supplied to the projector 16 through

suction hoses

20 and 20.

The processed object 13 stored in the large cylinder 10 is carried on the stirring plate main body 32 by the stirring plate 35 as the large cylinder 10 rotates, and the processed object 13 carried on the stirring plate main body 32 is not dropped by the return plate 33, and when it is lifted upward, the processed object 13 slides to the rear end portion 33b side of the return plate 33 and then drops to the bottom surface of the large cylinder 10.

This allows the treatment object 13 to be stirred while sliding in the direction of the inlet 31 of the large-sized cylinder 10 and the bottom plate 30 (the front-rear direction which is the axial direction of the large-sized cylinder 10), and thus allows the treatment object 13 to be stirred efficiently.

After removing burrs from the processed object 13 in the large-sized cylinder 10, the driving of the

projectors

16 and 16 is stopped, and the cylinder driving device 11 is stopped.

Then, the engagement of the engaging piece 36 is released, the opening/closing door 7 is slid in the opening direction, the cylinder support frame 9 attached to the opening/closing door 7 is also moved to the outside of the box 5, and the large cylinder 10 is also positioned outside the box 5.

In this state, the opening/closing cover 12 of the large cylinder 10 is positioned at the lower part, the locking state of the locking piece 29a is set to the open state, the opening 39 is opened by moving the opening/closing cover 12 upward by the handle 29, and the processed object 13 from which the burrs have been removed is dropped from the processed object storage container 40 below the opening 39 and discharged.

When the processed object 13 is discharged from the large-sized cylinder 10, the opening/closing cover 12 is closed, and after being locked by the locking piece 29a, the large-sized processed object 13 to be processed is introduced from the upper inlet 31 of the large-sized cylinder 10.

Then, the opening/closing door 7 is pressed in the direction of closing the opening 2 of the case 5, and the same operation as described above is performed to remove the burrs from the processed object 13.
