Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an apparatus for automatically removing paris generated on the surface or inside of metal products processed using metal processing machinery and equipment, using the metal corrosive action of chemicals. Regarding proposals.

Currently, even with the use of high-performance metal processing machinery and equipment,
In metal products processed by this, cutting, polishing,
After shearing or cutting, it is inevitable that sparks will occur at the processed edge due to the transferability, which is a characteristic of metals.

Various proposals have been made regarding this Paris removal method, but each has its own problems, and the following are
Examples will be given and explained to clarify the background leading to the proposal of the present invention.

First, for minute particles caused by polishing, light cutting, etc., use a puff or wire brush to remove them, and for relatively large particles caused by heavy cutting, forging, etc.
The methods used include barrel polishing, shot blasting, or direct polishing with a belt-shaped whetstone or grinding wheel.

Other methods for drilling holes include pouring liquid abrasive grains into the hole or using an electrode deburring method using an electrode.

A more unusual method is to put the material to be treated into a flammable gas, cause it to explode instantly, and use the heat generated to dissolve minute particles of paris.

In this way, appropriate measures have been devised and implemented depending on the purpose, that is, depending on the conditions such as the size of the paris and the location where they occur.

On the contrary, when these currently proposed methods are carefully considered, the following problems become apparent.

In other words, the method of removing minute particles using a puff or the like does not pose a problem if the area to be treated has a flat shape, but if the area to be treated is extremely uneven or has a complex shape, there is no problem. In some cases, the problem is that deburring becomes extremely difficult, and in the case of relatively large deburrs, the shot blasting method, etc., requires a large amount of material to be processed. In some cases, it is completely unsuitable for automatic processing, and there is an unavoidable drawback that it is impossible to automate and improve the efficiency of deburring work.

On the other hand, methods using liquid abrasive grains have the difficulty of post-processing and cleaning of the abrasive grains that have entered microscopic holes, and if an explosive dissolution method is to be adopted, the processing equipment must be installed. The problem that awaits us is that we will be forced to spend a large amount of money on this.

The present invention has been proposed in view of the above facts, and is a deburring device that can be used regardless of the shape of the object to be treated, the size of the object and the delinquent, and has excellent operability and high efficiency. To be more specific, it is possible to respond to the size and shape of the object to be treated by simply setting the size of the processing chamber, and to manage the processing time by selecting the chemical solution to be used and adjusting the concentration and temperature of the chemical solution. The present invention relates to a proposal for a deburr removal device that has the feature of being able to adapt to the size of deburrs by adjusting the conveyance speed of the object to be processed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described in detail below with reference to the accompanying drawings showing one embodiment.

The figure schematically shows the entire apparatus of the present invention, and (1) is a conveyor for conveying the processed material disposed in the apparatus of the present invention, which has a conveying function in the direction of arrow (A). Then,
When the objects to be treated are inputted into the conveyor (1) from the input port (IA), the degreasing chamber (2) → the washing chamber (3) → the deburring chamber (4) are separated and arranged in series.

c) (9d) (9e) (9f) are sequentially passed through to achieve the intended purpose of deburring and the necessary pre-processing and post-processing.

Below, we will explain each processing chamber individually. First, the degreasing chamber (2) is equipped with a degreasing liquid tank (20), a pump (21), a supply pipe (22), and an injection nozzle (23). When the pump (21) is driven, the degreasing liquid stored in the degreasing liquid tank (20') is transferred to the supply pipe (20').
2) from the injection nozzle (23) to the conveyor (
1), that is, it is emitted toward the object to be treated.

Therefore, when the object to be treated reaches the processing chamber (2) on the transport conveyor (1), it will be exposed to the degreasing liquid emitted from the injection nozzle (23), and the surface of the object will be degreased. becomes −.

The water washing chamber (3) is also basically the degreasing chamber (2).
It has the same configuration as . That is, this processing room (3) includes a flush water tank (3o), a pump (31), and a supply pipe (
82), an injection nozzle (33) is provided, and when the pump (81) is driven, the washing water stored in the washing water tank (3o) is delivered to the injection nozzle (3o) via the supply pipe (32).
83) to the transport conveyor (1), the material is ejected towards the object to be processed.

Therefore, when the object to be processed reaches the processing chamber (3) on the transport conveyor (1), it is bathed in washing water emitted from the injection nozzle (33), and the degreasing liquid adhering to the surface is washed away.

The deburring treatment chamber (4) is equipped with a corrosive liquid tank (40) for deburring, a pump (41), a supply pipe (42), and an injection nozzle (43), which drives the pump (41). If this is done, the corrosive liquid stored in the corrosive liquid tank (40) will
The point that the jet is emitted from the injection nozzle (43) to the conveyor (1), that is, the object to be processed, via the supply outlet (42) is that the above-mentioned degreasing execution chamber (2), water washing It has the same configuration as the processing chamber (3).

Facing this deburring treatment chamber (4), the corrosive liquid tank (40) is equipped with temperature control means for the corrosive liquid, namely a heater (44), a cooling pipe (45), and a temperature control means for the corrosive liquid. A sensor (46) is installed in this processing room (46).
) (It is possible to emit a corrosive liquid adjusted to a desired temperature from the injection nozzle (43) to the object to be treated which has reached 1.

Furthermore, in order to enhance the deburring effect, we have added injection nozzles (4
8) and a part of the supply pipe (42) that supports it are a motor (47) and a link mechanism (48) connected to the motor (47).

The deburring treatment chamber (4) is configured as described above, and the workpiece that has reached the treatment chamber (4) is kept at a desired temperature (a temperature at which the most efficient deburring effect can be obtained). Since the corrosive liquid is sprayed from a wide angle, the true purpose of the present invention, that is, a high deburring effect can be achieved.

The objects to be processed that have been processed in accordance with the intended purpose are further transported to the washing treatment chamber (5) by the transport conveyor (1), but in this treatment chamber (5), A flush water tank (50), a pump (51), a supply pipe (52), and an injection nozzle (53) are arranged, and when the pump (51) is driven, the water stored in the flush water tank (50) is Since the rinsing water is ejected from the injection nozzle (53) through the supply pipe (52) toward the object to be treated, the corrosive liquid adhering to the surface of the object to be treated is washed away.

A neutralization treatment chamber (6) is provided following this water washing treatment chamber (5), and this treatment chamber (6) includes a neutralization liquid tank (60
) pump (61), supply si' (62), injection nozzle (
63), and when the pump (61) is driven, the neutralizing liquid stored in the neutralizing liquid tank (60) is transported from the injection nozzle (63) via the supply pipe (62). Because it is emitted towards the conveyor (1), that is, the object to be treated, the surface of the object to be treated has a neutralizing effect, and in the next processing step, h
This will increase the effectiveness of anti-corrosion treatment.

The apparatus of the present invention is further provided with a rust prevention treatment chamber (7), which includes a rust prevention liquid tank (70),
Pump (71), supply pipe (72), injection nozzle (73)
is provided, and when the pump (71) is driven, the rust preventive liquid stored in the rust preventive liquid tank (70) is supplied to the supply pipe (7
2) from the injection nozzle (78) to the conveyor (
1), that is, since it is emitted toward the object to be treated, the surface of the object to be treated will be subjected to anti-rust treatment.

The object to be treated after passing through the anti-corrosion treatment chamber (7) is transported to the next drying treatment chamber (8) equipped with an air blow nozzle (80) with a built-in heater. The water adhering to the surface is completely removed at the exit (IB); 1.

Note that (81) represents a pump, and (82) represents a supply pipe.

In this way, deburring treatment, which is the original purpose of the present invention, and the pre-treatment and post-treatment for that purpose are performed.In the apparatus of the present invention, the object to be treated passes through each of the processing chambers. The processing liquid used in the processing chamber adheres to the surface of the processing chamber, and the air blowing processing chambers (9aX9bX9C) (9d) (9eX9D) are arranged between each of the above processing chambers to blow away this.

And none of these are air compressors! )−
(90) is equipped with an air pipe (91) and an air blow nozzle (92) that communicate with each other, and by blowing compressed air from the air blow nozzle (92) toward the processed material that has reached this processing chamber. It plays the role of blowing away the liquid adhering to the surface of the object to be treated and amplifying the treatment effect of the next treatment step.

Therefore, for example, in the air blowing chamber (9a) located next to the degreasing chamber (2), the degreasing chamber (
By passing through step 2), the degreasing liquid adhering to the surface of the object to be treated is blown away, thereby increasing the effectiveness of the next water washing treatment.

In addition, each air blowing treatment room is equipped with a dust collector (
10) for gas and mist collection) (
11) is carefully made, and in this processing room,
The mist generated when blowing away the liquid and the degassing chamber (
2), the gas generated in the deburring chamber (4), the neutralization chamber (6), etc. (the mechanism by which the gas generated in these chambers flows into the air blowing chamber will be described later) is transported through the duct (
11) and is collected in a dust collector (10) so that it can be heated to make it harmless.

As described above, in the apparatus of the present invention, each processing chamber is divided and provided in series, and its configuration is as follows.

That is, the used liquid recovery boxes (12a) (12b) are of appropriate size to constitute each processing chamber except the air blowing processing chamber.

It is constructed by providing a movable wall body (14) that moves up and down by the operation of the movable wall body (14).

And, in the air blowing treatment chambers (9a) to (9f),
The used liquid recovery receiving plate (15) is provided to be inclined toward the used liquid recovery box (12) for the liquid to be blown away by the spraying process, and each of the used liquid recovery box (12) has an inflow hole. (not shown), for example, in the air blowing chamber (9a) located next to the degreasing chamber (2), the degreasing liquid blown off from the object to be treated is collected and used. The used liquid collection boxes (12a) to (12f) each contain the aforementioned processing liquid storage tank (2o) (80X4
0) (50X60X70), and the liquids flowing into the used liquid recovery boxes (12a) to (12f) flow into the processing liquid storage tanks (2o) to (7o), respectively. The degreasing liquid that has flowed into the used liquid recovery box (12a) as in the above example is transferred to the degreasing liquid tank (
2o) and will be reused.

The wall that partitions each processing chamber is connected to an air cylinder (13), and consists of a movable wall (14) that moves up and down when the air cylinder (13) operates. There are various kinds of materials, some of which have considerable thickness (height), so when passing them to the next processing step, by moving the movable wall body (14), it is possible to remove obstacles to the passage. This was done to prevent this from happening.

In addition, since each processing chamber is divided by the movable wall (14) in this way, the corrosive reaction gas generated in the deburring processing chamber (4), for example, can be removed from the air blowing processing chambers ( 9bX9C) and flows into this processing chamber (9b) (9
