The present invention, in the CNC cutting machine used to cut the steel plate in the desired shape, by attaching a pen mechanism to the torch to allow the torch to cut the pen without cutting.

Description

Pen mechanism mounting torch {Pen device}

The present invention is to install a pen mechanism on the torch in the CNC cutting machine used to cut the steel plate in a desired shape, so that the torch does not cut the drawing by drawing the pen mechanism so that a certain purpose can be achieved without the direct cutting. .

In a generally known CNC cutting machine, a desired shape is created by a CNC program by CAD / CAM (not shown) and input to the CNC controller 1 as shown in FIG. 1 to operate the CNC controller 1. Plasma torch (5) or oxygen torch (6) is transversely conveyed from side to side along the X-axis rail (3) installed in the cutter body (2), and longitudinally forward and backward along the Y-axis rail (4) The main purpose is to cut the steel sheet W placed on the cutting table 7 according to the CNC program.

However, in the above CNC cutting machine, other purposes other than the above-mentioned main purpose include training of the cutting machine driver, test driving of the machine, and the like.

By the way, if you want to achieve the purpose of the above-described training of the cutter operator, test operation of the machine by using a CNC cutter equipped with a known plasma torch (5) or oxygen torch (6), the plasma torch after each CNC program (5) Or the steel sheet (W) should be actually cut by the oxygen torch (6), so that waste of resources and dust, cutting fragments, fumes (FUME), and various harmful gases generated during cutting are generated to faithfully meet a predetermined purpose. Can't achieve In addition, if the actual cutting during the test operation of the machine can not obtain the exact dimensions due to thermal deformation, there is a limit in the accuracy check.

On the other hand, the applicant has devised a prior application (20-2000-0033205) to solve the above problems by installing a pen mechanism driving the same as the existing torch for the purpose of efficient education to achieve the above purpose, Since the pen mechanism must be newly manufactured, the manufacturing cost was additionally required.

Therefore, the present invention, as described above, in the CNC cutting machine, not only for the purpose of obtaining a cutting product, but also for obtaining the same shape as that of the conventional plasma torch, which is cut for the training of the cutter operator or the test operation of the machine. In addition, it is possible to obtain a more precise shape than the shape of the actual cut member, and also does not generate dust, cutting debris, fume (FUME), various harmful gases generated during actual cutting, and do not actually cut the steel sheet, To reduce the waste, and to reduce the cost of manufacturing the machine, the pen tool P1 is mounted on the existing plasma torch 5 or the oxygen torch 6 to receive a command from the CNC controller 1 to move the X and Y axes. It is intended to provide a torch equipped with a pen mechanism capable of drawing.

1 is a conventional CNC cutting machine in which the cutter body 2 moves back and forth on the Y-axis rail 4, and the plasma torch 5 or the oxygen torch 6 transverses left and right along the X-axis rail 3. In

The present invention will first be described with a pen mechanism plasma torch.

2 is a known plasma torch, which is largely a plasma torch body 51, a nozzle 52 through which a plasma arc is discharged, a nozzle retainer 53 which fixes the nozzle 52 to the plasma torch body 51, It is comprised as the shield retainer 55 which fixes the shield 54 and the shield 54 to the said torch body 51. As shown in FIG.

3 is a pen mechanism-mounted plasma torch, which is an embodiment of the present invention, in which a nozzle retainer 53 is screwed to the plasma torch body 51, and a pen mechanism P1 is inserted into the nozzle retainer 53. The pen retainer 55 is fixed to the torch body 51 by being screwed to the nozzle retainer 53 while closely contacting one surface of the pen mechanism P1. will be.

Next, the pen mechanism P1 will be described in detail.

The pen insertion hole 59 is processed so that the pen 57 to be inserted is smoothly inserted into the center of the pen holder 58, and the pen 57 is inserted into the pen insertion hole 59, and a part of the pen holder 58 is pen holder 58. Protruding downward), the pen holder 58 'having a screw thread and a pen holder 58' for fixing the pen 57 is screwed and inserted into the pen holder 58. As is well known, the pen 57 has a projection, and a spring 56 is inserted and installed from the upper portion of the projection, and is fixed and held by the pen fixing device 58 ', and the impact of the pen 57 when drawing is performed. To alleviate this problem.

Hereinafter, a pen mechanism-mounted oxygen torch, which is another embodiment of the present invention, will be described.

4 is an already known oxygen torch and is generally composed of an oxygen torch body 61, a tip 62, and a tip retainer 63.

5 is a pen mechanism-mounted oxygen torch, which is another embodiment of the present invention, in which the pen mechanism P2 is inserted into the oxygen torch body 61, and the tip retainer 63 closely holds one surface of the pen mechanism P2. The pen mechanism (P2) is to be fixed to the oxygen torch body 61 by being screwed to the oxygen torch body 61 while being in contact.

Next, the pen mechanism P2 will be described in detail.

The pen 65 is inserted from the upper side of the cap 67 to protrude downward, and the cap 67 is screwed under the pen support 66 having the pen insertion hole. The pen holder 64 having a conical shape so that the upper end is in close contact with the oxygen torch body 61 has an insertion hole processed so that the lower end is opened and the pen support 66 is inserted therein to smoothly operate up and down. The strip 66 is inserted from the lower end of the pen holder 64, and the cap holder 68 is screwed onto the pen holder 64 to hold the pen support 66.

As described above, the present invention not only obtains a shape that is cut in the same way as a conventional torch for education of a cutter driver or a test drive of a machine by mounting a pen mechanism on an existing torch, but also actual cutting. It is possible to obtain a more precise shape than the shape of one member, and also to reduce the waste of resources because it does not generate dust, cutting debris, fume, and various harmful gases generated during actual cutting, and does not actually cut the steel sheet. In addition, since the pen mechanism is not manufactured separately, the manufacturing cost may be reduced.
