All flat plates that require wire drawing on the surface can be completed with this equipment. It has a wide range of applications and is mainly used for surface wire drawing of panels in craft factories, VCD factories, speaker factories, etc. After wire drawing, the surface of the plate presents clear straight hairline patterns, the surface of the plate is flat and smooth, the visual effect is good, the plate is aesthetically pleasing, and the plate is more upscale. Especially after wire drawing and then oxidation treatment, the added value of the product is greatly improved. Make the product more competitive in the market.

[0003] At present, the lifting components of triangular wire drawing machines mostly achieve the purpose of adjusting the lifting of the working plate by manually turning the wheel. The wheel is mostly installed at the lower part of the wire drawing machine, and it is necessary to squat and turn the wheel. If it is operated by one person, due to the large area of ​​the working plate itself, it is difficult to observe the distance between the sand belt and the upper surface of the working plate when squatting and turning the turntable. It is also necessary to squat repeatedly to adjust the height of the working plate. The bottom support of the current triangular wire drawing machine is mostly in the form of a frame. In order to increase the stability of the triangular wire drawing machine, a stabilizing rod is mostly installed between the legs. The stabilizing rod is generally placed in the middle and lower part of the adjacent legs. Under the restriction of the stabilizing rod, the lifting distance of the working plate is subject to certain restrictions, resulting in a limitation on the thickness of the processed plate. In addition, the current driving structure and the lifting structure are mostly directly exposed to the air, which are prone to accumulate dust over time, reducing the service life of the driving parts.

When using the device, the plate is placed on the working plate 3, the surface to be processed faces upward, the motor 11 is started, the motor 11 drives the corresponding bevel gear 1 7 to rotate, one bevel gear 7 drives another bevel gear 1 7 to rotate through the shaft 9, a pair of bevel gears 1 7 drives the meshing bevel gear 2 6 to rotate, a pair of bevel gears 2 6 drives the corresponding lead screw 5 to rotate, a pair of lead screws 5 drives the corresponding sliders 4 to slide upward along the corresponding U-shaped support plates 14, a pair of sliders 4 drives the working plate 3 and the plate to slide upward through the corresponding trapezoidal groove plates 13. When the plate slides to a position close to the abrasive belt 2, the motor 11 is turned off, the abrasive belt driving assembly is started, and the abrasive belt 2 runs at a high speed under the action of a group of pulleys. The abrasive belt is pressed by the hand pressure plate to process the corresponding position on the upper surface of the plate, and the working plate 3 is pushed. The working plate 3 drives a pair of trapezoidal slide bars to slide along the corresponding trapezoidal groove plates 13. The working plate 3 slides to drive the plate position to change, and different positions on the plane of the plate are processed. After one side is processed, the abrasive belt drive assembly is turned off, the plate processing surface is changed, and the motor 11 is started again to lift the other side of the plate to a position close to the abrasive belt 3 and then process the second side. The operation process is the same and will not be repeated. After the plate processing is completed, the processed plate is removed and the device is restored to its initial state.
