The present invention relates to a casting cutting device, and more particularly, a series of processes such as transporting and seating a casting for cutting a casting of a die casting system is performed by an automated robot, thereby preventing an operator from being exposed to a harsh environment. It is possible to increase the production efficiency, and to provide a door to the cutting device used in the die casting system to seal the space where the cutting work is performed, thereby preventing thermal and physical interference between the cutting device and other components during the cutting work. Of course, the present invention relates to a cutting device of a die casting system which enables the door and the robot arm to be driven organically in accordance with a control signal of a control means, thereby enabling fast and accurate driving of the device.

In general, casting refers to making a metal product of a desired shape by solidifying a metal solution in a mold. Representative examples of such castings are die castings which are suitable for producing precise products. The die casting is manufactured by casting a metal solution to a mold having a shape, and then solidifying the casting and then removing the casting from the mold to form a film on the surface and cutting unnecessary portions of the casting.

In general, the casting manufactured by die casting as described above is not a final product in itself, but is a primary product requiring physical and chemical processing. Accordingly, the die casting system is provided with a casting device for casting, for example, the die casting system is provided with a cutting device for cutting and separating the parts and the runner corresponding to the skeleton attached to the parts.

In the related art, a casting manufactured from a casting device is directly transported and seated by a worker to a cutting device so that the casting is cut by the cutting device. In addition, the cutting device is installed at a relatively large distance from the casting device in order to avoid adversely affecting the device and the product by the interference with the casting device, and to protect the worker from the heat generated in the casting device. Therefore, the moving distance and the transport time of the worker carrying the cast product are increased, thereby increasing the labor of the worker, and reducing the production efficiency. In addition, the cutting device causes a problem such as physical damage or damage to the device due to foreign substances generated during the cutting operation when the worker and other components are close because the space in which the cutting operation is not sealed.

The present invention was devised to solve the above problems, and the object of the present invention is to perform a series of processes such as transporting and seating of a casting for cutting a casting of a die casting system, which is performed by an automated robot. The present invention provides a cutting device for a die casting system using a robot arm that can prevent exposure to the environment and increase production efficiency.

In addition, another object of the present invention is to provide a door to the cutting device used in the die-casting system, by sealing the space in which the cutting operation, the thermal and physical interference between the cutting device and other components during the cutting operation It is to provide a cutting device of a die casting system using a robot arm that can prevent.

In addition, another object of the present invention is to provide a cutting device for a die casting system using a robot arm that enables the door and the robot arm to be driven organically to each other according to the control signal of the control means, enabling a fast and accurate drive of the device. .

The present invention for solving the above problems is in the die-casting system using a robot arm, the frame is extended so that the chamber is formed on the top of the die, the door is installed to open and close the frame to open or close the chamber A body comprising a; A cutting unit installed on the body to be positioned on the chamber and including a cutting blade rotated by a driving means; A sliding unit to be placed by the robot arm, the sliding unit being reciprocally slidably coupled to an upper surface of the die to allow the placed cutting object to be cut by the cutting blade; A jig installed on the sliding unit to fix the cutting object; Control means including a transceiver for transmitting and receiving a control signal with the robot and a door driver for opening and closing the door in accordance with the control signal; It is configured to include.

The present invention having such a feature may be more clearly described through the preferred embodiment accordingly. Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

As shown, the casting cutting device 50 according to the present invention includes a body 10, a cutting unit 20, a sliding unit 30, a control means (not shown).

The body 10 is formed by extending the plate-shaped frame 13 so that the chamber 15 is formed on the upper end of the die 11 having a substantially rectangular parallelepiped shape. The door 17 is opened and closed to the frame 13 so as to open or seal the chamber 15. Here, the chamber 15 is a space in which the cutting operation is performed by the cutting unit 20 to be described later.

The cutting unit 20 includes a cutting blade 23 located on the chamber 15 and rotated by a motor M as a driving means. Here, the configuration in which the cutting blade 23 is rotated by the motor (M) is not the same as the configuration of a conventional cutter and cutting device. That is, such a configuration is realized by the motor M and the rotating shaft 21 being connected to the pulley 25 and the belt 27 so as to be power-transmitted, and the cutting blade 23 is coupled to one end of the rotating shaft 21. Can be.

The sliding unit 30 is to hold the object to be held and moved by the robot arm (R) (5), the reciprocating sliding coupled to the upper surface of the die 11 reciprocally sliding the blood placed The cutting object 5 is cut by the cutting blade 23.

Thus, the sliding unit 30 is largely composed of a sliding body 34, seating surface 36, the cylinder 40.

The sliding body 34 is reciprocally coupled to the upper surface of the die 11 through an LM guide (LM Guide) 31, through the coupling with the transfer screw 33 is rotated by a motor (M) Drive force for sliding movement is given.

The seating surface 36 is hinged to the upper end of the sliding body 34 to be rotatable, and is given a turning force by the operation of the cylinder 40 to be described later.

The cylinder 40 is installed in the sliding main body 34, and rotates the seating surface 36 by causing the rod 41 to press the seating surface 36 during driving.

In addition, a jig 35 is installed on the sliding unit 30 to fix the cut object 5 to be placed therein, and the jig 35 has a limit sensor for limiting a moving range of the sliding unit 30. 37).

On the other hand, the sliding unit 30 is provided with inclined surfaces (38, 39) to be inclined downward to guide and collect the cut to be cut (5). In this case, the cutting object 5 is a state in which a part 1 and a runner 3 corresponding to a skeleton on which the part 1 is attached are normally integrated in a die casting system, and the part 1 is cut when cut. ) And runner 3 are separated. Therefore, it is preferable that a plurality of the inclined surfaces 38 and 39 are installed so that the separated parts 1 and the runner 3 can be individually guided and collected. (In the following description, the inclined plane on the left side of the drawing is called the first inclined plane, and the inclined plane on the right side of the drawing is called the second inclined plane.)

On the other hand, the above-described control means to open and close the door 17 of the body 10 in accordance with the operation of the robot arm (R), and for transmitting and receiving a control signal with the robot arm (R) And a door driver 19 which opens and closes the door 17 according to a transceiver and the control signal.

In more detail, the control means includes a body 10 for transmitting and receiving a control signal with a first transmitter / receiver (not shown) configured in the robot arm R and the first transmitter / receiver of the robot arm R. And a second transmitter / receiver unit (not shown) configured in the back and the like, and a door driver 19 for opening and closing the door 17.

Here, the control means may include a microprocessor (microprocessor) in which the work process is programmed, and is electrically connected to the above-described jig 35 and the cylinder 40 to suit the work process. The operation of 40 can be controlled.

In addition, the control means as described above may have a configuration electrically connected to the limit sensor of the jig 35, the motor for rotating the transfer screw 33 can be controlled to drive the sliding unit 30. .

Hereinafter will be described the operation relationship of the cutting device according to the present invention having the configuration and structure as described above. In addition, the following description is that the cutting device 50 according to the present invention persists in the die-casting system to be transferred from the casting device to the cutting object (5) to the cutting device 50 by the robot arm (R). It is exemplified.

When the cutting object 5 is held by the robot arm R, the first transmission receiver of the robot arm R transmits a holding completion signal to the second transmission receiver. The microprocessor of the control means drives the door driver 19 by the control signal to open the door 17. After the door 17 is opened, the second transmitter / receiver returns the door 17 to the first transmitter / receiver. Will send an open state.

Then, the robot arm R is inserted into the chamber 15 to place the cutting object 5 in the sliding unit 30, and when the robot arm R exits from the chamber 15, The door 17 is closed (closed) to allow the chamber 15 to be sealed. Thereafter, the sliding unit 30 in which the cutting object 5 is placed is moved toward the cutting blade 23 by the control signal of the microprocessor. Accordingly, the cutting object 5 is cut by the cutting blade 23, wherein the limit sensor 37 of the jig 35 is the sliding unit after the cutting object 5 is cut. The microprocessor senses the movement distance of the 30 and receives the signal from the limit sensor 37 to limit the movement distance of the sliding unit 30 and drive the cylinder 40.

At this time, it is a matter of course that the jig 35 is in a loose state (the state in which the cutting object 5 is not fixed) by the control signal of the control means at the same time as the cylinder 40 is driven.

In more detail, when the cutting object 5 (separated into the runner and the component) is separated from the sliding unit 30 by the bar, the runner 3 is dropped by its own weight after cutting and the second inclined surface. Guided through 39 is collected. The component 1 is guided and collected through the first inclined surface 38 according to the driving of the cylinder 40, which is formed by the rod 41 when the cylinder 40 is driven. By pressing the seating surface 36 is rotated accordingly to be inclined at a predetermined angle (preferably the same angle as the inclination angle of the first inclined surface). By the same principle as above, the runner 3 and the component 1 are separated from the seating surface 36 and collected separately.

As described above, after the cutting object 5 is cut, the sliding unit 30 must be restored to the initial position according to the control signal of the control means.

As described above, the present invention allows a series of processes such as transporting and seating of a casting for cutting a casting of a die casting system to be performed by an automated robot, thereby preventing an operator from being exposed to a harsh environment and improving production efficiency. There is an effect that can be increased.

In addition, the present invention has an effect that can prevent the thermal and physical interference between the cutting device and the other components during the cutting operation by providing a door to the cutting device used in the die casting system, sealing the space in which the cutting operation is made. . In addition, the above effects can be combined with each other in the die-casting system in close proximity to generate a derived effect that can reduce the movement trajectory and equipment space of the robot arm.

In addition, the present invention allows the door and the robot arm to be organically driven according to the control signal of the control means, thereby enabling the rapid and accurate driving of the device, thereby increasing the work efficiency and matching the automation of the device. .
