Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing apparatus, and more particularly to a processing apparatus for forming a desired pattern or the like on the surface of a workpiece used as a die for press working.

[0002]

2. Description of the Related Art Conventionally, an engraving machine as shown in FIG. 7 has been used to process a surface of a work piece into a desired shape. The engraving machine 1 includes a processing stage 2. The workpiece to be processed is fixed on the processing stage 2. Further, when processing the workpiece, the original plate 3 is prepared in advance. A pattern to be formed on the surface of the workpiece is formed on the surface of the original plate 3. Further, the engraving machine 1 includes a copying device 4 for tracing the pattern formed on the original plate 3. The copying apparatus 4 includes a pantograph. A processing head 5 is connected to the copying apparatus 4. The processing head 5 holds a spindle 6 for cutting the surface of the workpiece. While copying the workpiece surface with the spindle 6, the copying apparatus 4
By tracing the shape of the original plate 3, the surface of the workpiece fixed on the processing stage 2 by the spindle 6 interlocking is processed into the pattern of the original plate 3 prepared in advance. On the other hand, a method of processing the surface of a work piece into a desired shape by a chemical treatment such as etching is also known.

[0003]

However, when a desired pattern is to be formed on the surface of the workpiece by the conventional engraving machine 1, the original plate 3 on which a full-scale image or an enlarged image of the pattern to be formed is formed. Had to prepare in advance. At the time of processing, the pattern on the prepared original plate 3 had to be traced. Therefore, the work is time-consuming and inefficient. Further, when the conventional engraving machine 1 is used to form a pattern in which fine unit patterns are repeated, the work becomes very complicated. Further, a motor and a transmission mechanism for rotating the spindle 6 are required, which complicates the mechanism of the device. On the other hand, the unevenness of the processed surface due to a chemical treatment such as etching was flat and lacked in three-dimensional effect and gloss.

Therefore, a main object of the present invention is to provide a processing apparatus capable of easily and efficiently forming a three-dimensional glossy pattern.

[0005]

According to the present invention, there is provided a rod-shaped engraving means having a lower end formed with a projection corresponding to a unit pattern for engraving on the surface of a workpiece, and the engraving means above the workpiece. Holding means for holding the means, displacement means provided on the holding means for displacing the embossing means in the axial direction thereof, and provided for the holding means for urging the embossing means toward the lower end thereof Is a processing device including a biasing means, a transfer means for transferring the holding means at a predetermined pitch, and a main body for supporting the holding means and the transfer means.

[0006]

The main body supports the holding means and the transfer means. The holding means holds the stamping means above the workpiece. The embossing means is displaced by the displacement means provided in the holding means so as to widen the interval with the workpiece in the axial direction. Then, the engraving means is urged from the upper end direction to the lower end direction by the urging means and collides with the workpiece surface. In this way, the unit pattern is engraved on the surface of the work piece by the protrusion at the lower end of the embossing means that has crashed into the surface of the work piece. When one unit pattern is formed, the transfer means transfers the holding means at a predetermined pitch. In this way, the unit patterns are sequentially and repeatedly formed at a predetermined pitch,
A pattern formed by combining them is formed on the surface of the workpiece.

[0007]

According to the processing apparatus of the present invention, it is not necessary to prepare an original plate on which an original size image or a magnified image of the pattern to be processed is prepared in advance, and it is not necessary to trace the pattern on the original plate during processing. Therefore, the work can be efficiently performed in a short time. According to this processing device,
Since it is easy to repeatedly form unit patterns on the surface of the work piece at a predetermined pitch, it is possible to easily form a pattern in which fine unit patterns are repeated.
Furthermore, various unit patterns can be selected by selecting the shape of the protrusion formed at one end of the embossing means, and it is possible to easily create a unique three-dimensional and glossy pattern that is a combination of them. And can be formed efficiently. Further, since the processing is performed by stamping, there is no problem such as cooling processing of frictional heat due to rotation of the spindle during processing and processing of chips unlike the related art, and the working process can be simplified. Further, since a motor for rotating the spindle is unnecessary, the mechanism of the device can be simplified.

The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.

The machining head 78 is displaced by following the holes in the upper pitch plate. The operator stops the displacement of the machining head 78 by the pantograph 80 when the marking 50 of the embossing machine 12 attached to the machining head 78 reaches the place to be stamped on the workpiece. Then, the knob 60 of the embossing machine 12 is pinched and the handle 58 is rotated clockwise in the drawing. When the handle 58 is rotated, the plate cam 56 is rotated. Then, the swinging member 26 abutting on the outer peripheral surface of the plate cam 56 swings upward along the outer peripheral surface of the plate cam 52, and lifts the rod-shaped member 32 substantially vertically upward. As the rod-shaped member 32 is lifted, the flange member 34 of the rod-shaped member 32 moves upward. When the collar member 34 moves upward, the spring 36 causes the collar member 34 and the through hole 1 of the body 12 to move.
It is compressed between the upper end of 6 and.

When the tip of the rocking member 26 rocked upward reaches the projection 56a of the plate cam 56, the rod-shaped member 3
2 is urged downward by the compressed force of the spring 36 to move, and moves in a substantially vertical downward direction, and one end of the marking 50 collides with the surface of the workpiece. Then, the protrusion 5 at one end of the stamp 50
A unit pattern of 0a is stamped on the surface of the workpiece.

When one unit pattern has been formed, the engraving machine 12 is moved by following the next pitch hole on the pantograph 80. In this way, by sequentially forming the unit patterns repeatedly at a predetermined pitch, a unique pattern formed by combining them is formed on the surface of the workpiece. An example of the work piece on which the continuous pattern is formed is shown in FIG. In this example, the workpiece is used as a stamping die. By performing press working with the die 90, for example, a decorative plate 92 such as a name plate having a three-dimensional and glossy scale-like ground pattern as shown in FIG. 4B can be manufactured. In addition,
In this embodiment, the workpiece used as the mold is processed, but the present invention is not limited to this, and the decorative plate 92 having a three-dimensional, glossy ground pattern may be directly manufactured.

Further, the projection 5 formed at one end of the stamp 50
The shape of 0a is, for example, rectangular, triangular, T-shaped, star-shaped,
Various shapes such as triangular pyramid and trapezoid can be prepared. By selecting the marking 50 and applying it to the processing apparatus 10 according to the pattern to be formed on the surface of the workpiece, it is possible to form various patterns as shown in FIG. 5, for example, on the surface of the workpiece.

According to the processing apparatus 10 of this embodiment, it is not necessary to prepare in advance an original plate on which an original size image or an enlarged image of the pattern to be processed is formed, and it is not necessary to trace the pattern on the original plate during processing. Therefore, the work can be efficiently performed in a short time. Further, according to the processing apparatus 10, since it is easy to repeatedly form unit patterns on the surface of the work piece at a predetermined pitch, it is possible to easily form a pattern in which fine unit patterns are repeated. it can. Further, the protrusion 50 formed at the lower end of the embossing means
By selecting the shape of a, various unit patterns can be selected, and a three-dimensional, glossy and unique pattern formed by combining them can be easily and efficiently formed. Further, according to the processing by engraving, the unevenness of the processed surface can be inclined, so that the three-dimensional effect and the gloss are increased. Further, since the processing is carried out by stamping, there is no problem such as cooling processing of frictional heat due to rotation of the spindle during processing and processing of chips unlike the conventional case, and the working process can be simplified. In addition, a motor for rotating the spindle is unnecessary, and the mechanism of the device can be simplified.
