Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flash chip cutting device of a conformer for automatically cutting flash chips, which are surplus of irregular shapes.

[0002]

2. Description of the Related Art For example, in order to use a metal such as aluminum (workpiece) and heat it to process and form it into a desired shape, for example, a pipe shape, a predetermined conformer including a rotating cylindrical wheel is used. Has been developed and used.

[0003] In this metal working and forming apparatus, usually,
Due to the fact that it is configured to supply a large amount of processing metal material in advance, of the supplied metal objects, those other than those supplied for the processing are generated as surplus metal objects on the wheel and its surroundings. The surplus metal (hereinafter referred to as flash waste) must be sequentially discharged to the outside of the wheel.

[0004]

However, since the flash waste is in a high temperature state due to residual heat after molding, has high stickiness, and has an irregular shape, its handling (cutting operation) is troublesome. Because it is difficult to automate and mechanize, it is the fact that the worker is exclusively near the machine and removes it manually (for example, when crushed by hand and cut to an appropriate size, cut with a cutter or the like). It is.

[0005] Further, since the flash dust itself is in a high temperature state, the shape does not remain constant. Therefore, the shape is freely changed by the pushing force when pushed out later, and the irregular shape is formed. Therefore, it is difficult to take off or cut in a stable state at all times.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a flash dust cutting device of a conformer capable of cutting flash dust in a simple and reliable manner. .

[0007]

That is, the present invention according to claim 1 is a flash dust cutting apparatus for a conformer which scrapes flash dust generated between a wheel and a die chamber with a scraper and cuts it with a cutter. A passing sensor for detecting a passing amount of the generated flash chips, a cooling device provided downstream of the passing sensor in the moving direction of the flash chips and blowing cool air toward the flash chips, and a cooling device. And a rotary cutter provided on the downstream side in the moving direction of the flash debris.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic configuration diagram showing a flash scrap cutting device for a conformer according to this embodiment. The flash waste cutting device of this embodiment includes a passage sensor 1, a cooling device (comprising a plurality of systems) 2, and a rotary cutter 3.

In the figure, reference numeral 4 is a scraper, 5 is a wheel, 6 is a die chamber, 7A is a continuous sheet-like metal material for processing (in this embodiment, aluminum, but of course, synthetic resin or the like), 7B is a metal workpiece processed into a predetermined shape (in this embodiment, a continuous pipe shape), 7C is a wire (core portion) covered with the metal workpiece 7A, and 8 is flash dust.

The passing sensor 1 detects the passing amount of the flash chips 8 before the cutting of the flash chips 8. In this embodiment, the passing sensor 1 detects the passing amount by optical means provided immediately above the scraper 4. . This passage sensor 1
Is connected to a flow control unit 24 (see FIG. 2) of the cooling device 2 to be described later, and outputs a predetermined signal when the passage amount is detected. In addition, mechanical, physical, and other various means can be applied to the passage sensor in addition to the optical means.

A plurality of cooling devices 2 are provided downstream of the passage sensor 1 in the direction of movement of the flash chips 8,
Cold air is blown toward the flash chips 8 in a high temperature state due to the residual heat after molding, and cooled and solidified to at least a temperature at which the shape is stabilized. The cooling device 2 of this embodiment includes a cooling air source 21 and an electromagnetic valve 22 for controlling a flow rate.
And a housing 23 provided with a plurality of outlets 23A. For example, a corder or the like that cools to about -40 degrees is used. The electromagnetic valve 22 is provided with a flow control unit 24 as shown in FIG. The flow control unit 24 operates in response to the output signal from the passage sensor 1 to output a control signal to the electromagnetic valve 22 to adjust the opening and closing amount of the valve (the flow rate of cooling air).

The rotary cutter 3 is provided in the vicinity of the outlet of the housing 23, and cuts the flash dust 8 which has been cooled and solidified inside the housing 23 and has a stable shape.

Therefore, according to this embodiment, the passage sensor 1 detects the amount of the generated flash debris 8 in accordance with the amount of passage and generates an appropriate signal corresponding to the amount of passage.
4 is output. In the flow control unit 24 to which this signal is input, for example, when the passing amount of the flash debris 8 increases (decreases), the electromagnetic valve 22 is widely opened (closed) in accordance with the increase, and is fed toward the outlet 23A. By increasing (decreasing) the flow rate of the cooling air, it is possible to perform cooling sufficiently corresponding to the flash chips 8 that increase (decrease).

[0014]

As described above, according to the present invention, a passage sensor for detecting a passage amount of flash debris,
Since a cooling device is provided downstream of the passage sensor in the direction of movement of the flash chips and blows cold air toward the flash chips, and a cutter is provided downstream of the cooling device in the direction of movement of the flash chips, the shape due to residual heat is provided. Easy to cut flush debris, which was not easy to handle and difficult to handle.
In addition, it can be performed reliably and stably, and the reliability of the conformer can be greatly improved.
