The workpiece rotating mechanism 90 includes a rotary driving member 93 and a stage 95 connected to the rotary driving member 93. The rotary driving member 93 is capable of driving the stage 95 to rotate about the third axis Z-axis.

S102, the workpiece 200 is fixed on the stage. In the embodiment, the workpiece 200 to be processed is a thin metal plate having a certain mechanical strength and hardness. The workpiece 200 includes a processing surface 201 to be drawn, and the processing surface 201 has a marking pattern 203 at a center position thereof. The workpiece 200 is fixed in the stage 95 of the wire drawing machine 100, so that the processing surface 201 faces away from the stage. 95.

S103, adjusting the position between the drawing wheel 57 and the workpiece 200 such that the drawing wheel is located above the workpiece 200. In the embodiment, the workpiece rotating mechanism 90 is driven to move along the X-axis direction of the second axis by the second translation mechanism 70, so that the workpiece 200 on the stage 95 is close to the drawing wheel 57, and the drawing is driven by the first driving member 23. The mechanism 50 is moved toward the workpiece 200 in the Y-axis direction of the first axis. Finally, the wire wheel 57 is positioned above the approximate center of the machined surface 201 of the workpiece 200.

S104, adjusting the position of the wire drawing wheel 57 to be close to the surface of the workpiece 200. In the embodiment, the lifting assembly 33 drives the wire drawing mechanism 50 to move along the third axis Z direction, so that the wire drawing wheel 57 is close to the workpiece 200 and the workpiece 200 The approximate middle position is relatively accurate.

S105, the second driving member 55 drives the wire drawing wheel 57 to rotate about the second axis X-axis.

At S106, the position of the wire drawing wheel 57 is adjusted again to abut against the surface of the workpiece 200. In the present embodiment, the elevating unit 33 drives the wire drawing wheel 57 to move in the Z-axis direction of the third line until it abuts against the substantially central position of the processing surface 201 of the workpiece 200. In the present embodiment, the wire drawing wheel 57 abuts against the outer edge of the marking pattern 203 at the center of the workpiece 200.

S107, the first driving member 23 drives the drawing wheel 57 to move from the substantially central position of the workpiece 200 toward the edge of the workpiece 200 in the Y-axis direction of the first axis. In the present embodiment, the wire pulling wheel 57 is moved away from the pattern 203 in the Y-axis direction of the first axis by the driving of the first driving member 23. At the same time, the rotary driving member 93 drives the workpiece 200 to rotate about the third axis Z axis, so that the surface of the workpiece 200 is ground to form a partial curved texture.

S108, adjusting the position height of the wire drawing wheel 57 to be again resisted to a substantially central position of the processing surface 201 of the workpiece 200; the first driving member 23 continues to drive the wire drawing wheel 57 on the surface of the workpiece 200 along the first axis Y axis The direction moves while the rotary driving member 93 drives the workpiece 200 to rotate about the third axis Z-axis, and the surface of the workpiece 200 forms a curved texture again;

Step S108 is repeated, and the relative running speed of the drawing wheel 57 and the workpiece 200 is coordinated until the processing surface 201 of the workpiece 200 exhibits a swirling pattern from the center position.

It can be understood that the step S103 can be omitted, and only the workpiece 200 needs to be placed on the stage 95 in step 2, so that the wire drawing wheel 57 is located above the substantially central position of the processing surface 201 of the workpiece 200.

It can be understood that, when the position height of the wire drawing wheel 57 is adjusted to be close to the workpiece 200 and the surface of the workpiece 200 in steps S104 and S106, the lifting mechanism 30 does not necessarily need to adjust the position height of the wire drawing wheel 57, and the workpiece can be directly adjusted. The relative positional relationship between the 200 and the wire drawing wheel 57 causes the wire drawing wheel 57 to be brought close to and eventually resist the working surface 201 of the workpiece 200.

The processing method of the metal casing decorative pattern adopts a drawing wheel 57 which is an elastic nylon grinding wheel, and the workpiece 200 to be processed is made of a metal material having a certain hardness, so the above-mentioned drawing is formed on the surface of the workpiece 200. The shallow texture does not change the outer dimensions of the workpiece 200 to be processed, nor does it reduce the strength of the workpiece 200. In addition, since the processing pattern is formed by rotating the workpiece 200 and moving the drawing wheel 57 to form a whirlwind-like brushed texture on the surface of the workpiece 200, the method for forming the decorative pattern is simple, the flow is short, and the processing is performed. The pattern is a whirlwind drawing pattern, which has a strong visual effect and overcomes the single defect of the traditional drawing pattern. Furthermore, the above drawing method can be widely applied to aluminum-plastic panels, fireproof panels, flowerless panels, household appliances, architectural decoration, etc., to meet the needs of consumers. In summary, the processing method of the metal shell decorative pattern processing method of the present invention has a simple structure, and the drawn texture of the drawn wire has a strong visual effect.
