It can be discarded as it is, and no special work such as collection and processing is required.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for removing burrs on a work and cleaning the work by spraying fine ice on the work.

[0002]

[Prior art]

 Conventionally, a so-called water jet device that has been used for deburring a work such as an IC frame or for cleaning and polishing is to spray ultra-high pressure water that draws a constant trajectory onto a work to process it. However, a deburring device using ultra-high pressure water required a large-scale device for the pump to generate ultra-high pressure water.

In addition, in the case of utilizing for cutting, etc., there has been a means for increasing the processing efficiency by adding an abrasive or the like to ultra-high pressure water. However, it is difficult to treat the abrasive mixed in the ultra-high pressure water after jetting, and there has been a demand for the development of a simple deburring device that does not require such treatment.

[0004]

[Problems to be solved by the present invention]

 The present invention is provided to meet the above-mentioned demands. By spraying fine ice particles onto a work, deburring, cleaning and polishing effects can be achieved with a pressure that is not too high, and post-spraying processing can be performed. The object is to provide a fine ice jet type work processing device that is not required like water.

[0005]

[Means for solving problems]

 In order to solve the problem, the present invention connects a connecting pipe to a cold air generating device that generates cold air by supplying compressed air, and connects a fine ice transfer pipe from a fine ice making machine in the middle of the connecting pipe. A fine ice jet work processing device characterized in that a jet nozzle is connected to the other end, and fine ice cubes are jetted from the jet nozzle to the workpiece by cooled compressed air passing through the connecting pipe, and the workpiece is processed. Is provided.

【Example】

 As can be understood from FIG. 1, the present invention comprises a compressed air tank 1, a cold air generator 3, a connecting pipe 4, a fine ice making machine 9, a fine ice transfer pipe 10, and a jet nozzle 6, which is a fine ice jet work processing device. Is.

In the figure, reference numeral 1 denotes a compressed air tank. From the compressed air tank 1, 5 to 15 kg / cm 2 of compressed air is sent to a cold air generator 3 through an air supply pipe 2.

The cold air generator 3 has been commercially available in the past, and cools air to a temperature of 35 degrees to minus 60 degrees Celsius (degrees C.) by passing compressed air, and at the same time, the vacant portion 5 of the connecting pipe 4 is cooled. The inside is blown toward the nozzle 6 direction. The cold air generator 3 discharges the heated air in the direction opposite to the nozzle 6.

The outer periphery of the connecting pipe 4 is covered with a heat insulating material 7 almost all around so that the high temperature at the work site is not transmitted to the connecting pipe 4. Compressed air flows in the inner space 5 of the connecting pipe 4 in the direction of the arrow.

A fine ice insertion port 8 is opened in the middle of the connecting pipe 4, and the fine ice produced by the fine ice maker 9 is supplied through the fine ice transfer pipe 10. It is preferable to use an internal screw type as the fine ice transfer pipe 10 in order to have a forced transfer force.

A rotary injection nozzle 6 is attached to an end of the connecting pipe 4 via a rotary valve 11. The rotary jet nozzle 6 is given a rotational force by a separately provided motor (not shown), and the jet trajectory can be adjusted to be suitable for machining. In the figure, 12 is a conveyor, 13 is a work, and 14 is fine ice.

[0012]

【effect】

 Since the present invention is constructed as described above, it has the following effects.

First, since the substance to be sprayed onto the work is the fine-grained ice 14, unlike the case of spraying a fluid substance, the work effect such as deburring on the work 13 is improved by spraying at a low pressure. Therefore, it is possible to achieve a processing effect similar to or even higher than that of the ultra-high pressure water processing device without requiring a large-scale device such as an ultra-high pressure water generation pump.

Secondly, the jetted fine-grained ice 14 is solid at the time of jetting, but since it is ice, it melts at room temperature and changes into the original water, so a special abrasive was mixed. Unlike the case, it can be discarded as it is, and at the same time, it does not require special work such as collection and treatment.
