CONSTITUTION: In working the metal of the prescribed shape by metal working and forming devices 5, 6 using the metallic material consisting of the prescribed materials, the operation of a rotary cutter 3 is temporarily interrupted based on the detected signal to be outputted from a thick wall part detecting sensor 1 when the thick wall part of a nonmonolithic metal 4 exceeding the prescribed value is generated. A motor to drive a roller on the upper side is temporarily interrupted until the thick wall part passes a part of the rotary cutter 3, and the roller on the upper side is pushed outward by the passage of the thick wall part, and temporarily evacuated. No toque of the motor is applied and no cutting is achieved even when a cutter 31A is butted on the thick wall part.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indeterminate shape in which excess metal objects having an indefinite shape, which are often generated when forming a metal object in a predetermined shape, are cut at specific intervals by a cutting means, and are discharged and processed to the outside. The present invention relates to a method and a device for discharging metallic materials.

[0002]

2. Description of the Related Art For example, a metal forming apparatus such as a predetermined conformer has been developed and used for forming and forming a desired shape, for example, a cylindrical shape, using a metal such as aluminum.

Further, in this metal working / forming apparatus, normally,
Due to the fact that it is configured to supply a large amount of processing metal objects in advance, those other than those used for the processing are generated as surplus metal objects, but these surplus metal objects are always generated. And should be sequentially discharged to the outside of the device.

[0004]

By the way, the generation shape of this surplus metal material is not always constant, for example, as shown in FIG.
As shown in FIG. 7 and FIG. 7, the surplus metal object 100 has partially different thicknesses T and the like, and sometimes large lumps 101 are generated as shown in FIG.

Therefore, the handling of the surplus metal material is troublesome, and the discharge work to the outside is also troublesome, so that it is difficult to automate or mechanize, and the worker is always at the side and manually. It is designed to be cut at intervals.

Therefore, in view of the above-mentioned circumstances, an object of the present invention is to provide a method and an apparatus for discharging an irregular shaped metal that can automatically discharge an excessive shaped metallic substance to the outside. It is a thing.

[0007]

That is, according to the invention described in claim 1, a large number of indeterminate-shaped surplus metal objects, which are generated when a metal object is formed into a predetermined shape, are cut by a cutting means at specific intervals. This is a method for discharging irregularly shaped metal objects to be discharged and treated externally, and when the thickness of the irregularly shaped metal object exceeds a certain dimension, the thick portion is detected and The cutting means retracts rearward from the passage of the irregular-shaped metal material until the portion passes through the cutting means, and temporarily suspends the operation of the cutting means. Further, according to the invention of claim 2, the excess metal material having an indefinite shape, which is generated in large numbers when the metal material is formed into a predetermined shape, is cut at a specific interval by the cutting means, and is discharged and processed to the outside. A discharge device for a fixed-shaped metal object, wherein when the generated irregular-shaped metal object is a thick-walled portion having a thickness exceeding a certain dimension, a detection means for detecting the thick-walled portion and the thick-walled portion is cut. The cutting means retreats backward from the passage of the irregular-shaped metal object until it passes the means, and temporarily suspends the operation of the cutting means.

[0008]

According to the present invention, a wall thickness portion of the surplus irregular shaped metal that exceeds a certain wall thickness dimension is generated, and when the detection means detects this wall thickness portion, the control unit operates in response to this detection operation. The cutting means retracts rearward until the thick portion passes, and controls the cutting operation so as to temporarily interrupt the cutting operation.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic configuration diagram showing an irregular-shaped metal material discharge processing apparatus according to this embodiment. In addition to the guide / guide plate 10, the discharge processing device for irregular shaped metal of this embodiment includes a thick portion detection sensor 1, a control unit 2 (see FIG. 2), a rotary cutter 3, and a forward / backward movement mechanism 9 (see FIG. 4)) and.

In the figure, reference numeral 4 is a surplus of irregularly shaped metal material that is sequentially discharged, 5 is a wheel that constitutes a part of a metal material processing and molding apparatus, and 6 is a part of this apparatus. Dice device, 7A is a continuous sheet metal material for processing (aluminum in this embodiment), 7B is a metal work having a predetermined shape (continuous pipe shape in this embodiment), 7
C is a wire rod at the center, and 8 is a scraper for scraping off the amorphous metal object 4 attached to the wheel 5.

The thick portion detecting sensor 1 detects the thick portion when the thick portion of the amorphous metal object 4 that is generated exceeds a certain dimension. In the thick portion detection sensor 1 of this embodiment, as shown in FIG. 3, a position at a preset minimum thickness is used as a reference (in this embodiment, the rotary shaft 11 of the retracting roll 11 at the lowest position in FIG. 3).
With reference to the position of A), measure how much the height changes from then on by appropriate means (for example, by optically reflecting light of a specific wavelength or by electromagnetic detection by a proximity sensor). The thickness of the amorphous metal object 4 is indirectly detected by.

That is, in the thick portion detecting sensor 1 of this embodiment shown in FIG. 3, the rotation shaft 11A position L1 of the pull-in roll 11 at the lowest position and the maximum rising state in which the thick portion 4A rides when passing through. The height difference X between the rotary shaft 11A and the position L2 of the rotary shaft 11A is detected, and a detection signal corresponding to the height difference X is output to the control unit 2.
1A is dropped in a vertically elongated guide groove 13 engraved in the vertical direction, and a spring (not shown) constantly applies a downward elastic force. In addition, the other pull-in roll 12 that forms a pair of rolls with the above-mentioned pull-in roll 11
Is rotatably fixed at a predetermined position and is forcibly rotated by a motor (not shown).

The control unit 2 retreats until the thick-walled portion 4A of the irregular-shaped metal object 4 having a certain thickness exceeds the rotary cutter 3 and temporarily suspends the operation of the cutting means. A predetermined detection signal output from the thick portion detection sensor 1 is input, and there is a passage of a thick portion 4A in which the thickness dimension of the irregular metal object 4 detected from the detection signal exceeds a certain value. When this is determined, a predetermined control signal is immediately output to the rotary cutter 3.

The rotary cutter 3 is composed of a pair of upper and lower rotating rollers 31 and 32 which rotate at a constant angular velocity (the angular velocity can be changed if necessary), and cuts the irregular metal object 4. It has become.

A cutter 31A is formed on the outer peripheral surface of the upper rotary roller 31, and as shown in FIG. 4, a spring 91 having a predetermined elastic force F ₀ (described later).
Due to this, a constant pressure contact force F ₀ is always applied. Therefore, normally, that is, in the case where the irregularly shaped metal object 4 having a thick dimension of a certain value or less passes through the rotary cutter 3,
The cutter 31A performs a regular intermittent operation, that is, it intermittently operates and presses against the irregular-shaped metal object 4, and the irregular-shaped metal object 4 passing between the rotating rollers 31 and 32 is pressed with a previous pressing force F.
The total force F _{1 of 0} and the torque T of the motor 3 for forcibly rotating the rotary roller 31 (the thick portion 4
Let F ₂ be the maximum cutting force required to cut the amorphous metal object 4 when the thickness is less than or equal to the thickness dimension of A.
_{By 1} > F ₂ ), the amorphous metal material 4 is cut into chips at substantially equal intervals.

Further, when the irregular-shaped metal object 4 having a thick-walled dimension equal to or larger than a certain value (that is, the thick-walled portion 4A) passes through the rotary cutter 3, the motor 33 is driven by the control of the controller 2. Since it is temporarily interrupted, no torque is generated even if the elastic force F ₀ of the previous spring 91 acts, and even if the false cutter 31A is pressed against the thick portion 4A, the thick portion 4A is cut. I don't have the power to do it. Therefore, the rotating roller 31 only rotates following the traveling operation of the irregular-shaped metal object 4, and the cutting operation is not performed. Also,
After passing through the thick portion 4A, the rotating roller 31 on the upper side starts to rotate at the original angular velocity when the motor 33 is re-driven by the control signal from the controller 2.

As shown in FIG. 4, the rotating roller 32 on the lower side discharges the amorphous metal object 4 in a predetermined direction while constantly rotating at a constant angular velocity by the motor 34 fixed to the mounting base 92. It has become.

As shown in FIG. 5, the advancing / retreating mechanism 9 is for retracting the upper rotary roller 31 rearward from the passage of the irregular metal object 4 until the thick portion 4A passes through the rotary cutter 3. In this embodiment, in FIG. 4, a slide portion 93A that moves up and down while engaging with a long hole 92A provided in the mounting base 92 is provided, and an elevating body 93 on which the motor 33 is fixed, and this elevating body 93. Is provided with a predetermined elastic force F ₀ .

In this embodiment, the advancing / retreating mechanism is not actuated by the elastic force of the spring, but of course the invention is not limited to this. For example, an air cylinder or solenoid may be used. is there.

Next, an explanation will be given of the method for discharging an irregular-shaped metal material according to the present invention, using the apparatus for discharging an irregular-shaped metal object according to this embodiment. When a metal material made of a predetermined material (aluminum in this embodiment) is used to perform metal processing of a predetermined shape by the metal-work forming devices 5 and 6, a thick wall of the irregular-shaped metal material 4 exceeding a certain thickness. When the portion 4A occurs, the operation of the rotary cutter 3 is temporarily interrupted by the control unit 2 based on the detection signal output from the thick portion detection sensor 1.

That is, the operation of the motor 33 for driving the upper rotary roller 31 is temporarily suspended until the thick portion 4A passes through the rotary cutter 3, so that the thick portion 4A of the amorphous metal object 4 is By passing, the upper rotation roller 3
1 will be pushed upwards, making it a good idea to temporarily retract. In this case, even if the cutter 31A just comes into contact with the thick portion 4A, the torque of the motor 33 is not acting and the cutting operation is not performed. As a result, it is possible to prevent troubles such as the thick wall portion 4A being clogged in various places and the rotary cutter 3 being damaged.

[0022]

As described above, according to the present invention, a wall thickness portion of the surplus irregular-shaped metal which exceeds a certain wall thickness dimension is generated, and when the wall thickness portion is detected by the detecting means,
In response to this detection operation, the control unit operates so that the cutting means retracts rearward until the thick portion passes and controls the cutting operation so as to temporarily interrupt the cutting operation. With this configuration, it becomes possible for the operator to automatically perform the work of removing the surplus amorphous metal, which has always been done by hand, by a machine, that is, to realize full automation.
