Description

Technical field:

[0001] The invention relates to the technical field of automated production, in particular to a wire drawing machine. Background technology:

[0002] Surface brushing is a surface treatment method that forms lines on the surface of the workpiece by grinding the product to achieve a decorative effect. Since surface brushing can reflect the texture of metal materials, it has been loved by more and more users and has been used more and more widely. The processing method of surface brushing should be selected according to the requirements of the brushing effect and the size and shape of the workpiece surface. There are two types of brushing methods: manual brushing and mechanical brushing.

[0003] Common mechanical wire drawing methods include wide abrasive belt wire drawing, which is the most traditional wire drawing method and is used for flat wire drawing, especially suitable for plate processing. The abrasive belt rotates at high speed, and the plate passes through the abrasive belt from the conveyor belt for grinding and wire drawing. Usually, stainless steel plates, aluminum alloys and other plates are made into wire drawing semi-finished products, so that they can be further made into products with plates as raw materials, such as stainless steel elevator wire drawing door panels, stainless steel counters, aluminum alloy chassis, etc. The lines drawn in this way are usually very thin and short, which can be called snowflake lines. This method requires the abrasive belt to have good adhesion so that the line effect of the plate can be more uniform.

[0004] Since traditional mechanical wire drawing can usually only complete flat wire drawing, manual wire drawing is still required for wire drawing on non-flat surfaces such as arc surfaces, bevel surfaces and curved surfaces. Manual wire drawing is not only inefficient, but the wire drawing effect is also greatly affected by the workers' experience. It is generally difficult to ensure the consistency of the product wire drawing effect.
