Wire drawing machine and machining method thereof

Abstract

The invention provides a wire drawing machine and a machining method thereof. The wire drawing machine comprises a machine frame, a first driving mechanism, a second driving mechanism, a plurality of roll shafts, a wire drawing belt, a downward pressing device and a fixture device. The first driving mechanism and the second driving mechanism are fixedly connected with the machine frame. The first roll shaft is connected with the machine frame, and the first driving mechanism drives the first roll shaft to rotate. The second roll shaft is rotationally connected with the second driving mechanism, and the second driving mechanism drives the second roll shaft to move in the axial direction of the second driving mechanism. The third roll shaft is connected with the machine frame. The wire drawing belt is wound on the multiple roll shafts. The downward pressing device comprises a third driving mechanism and a downward pressing assembly. The fixture device comprises a tool fixture, the tool fixture and the downward pressing assembly are located on the two sides of the wire drawing belt correspondingly, the tool fixture is opposite to the downward pressing assembly, and the third driving mechanism drives the downward pressing assembly to push the wire drawing belt towards the tool fixture. The invention further provides the machining method of the wire drawing machine. The wire drawing machine and the machining method thereof have the advantages of being good in wire drawing effect and high in wire drawing quality and wire drawing efficiency.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a wire drawing machine and a processing method of the wire drawing machine. Background technique [0002] With the popularization of mobile phones, people attach great importance to the appearance of mobile phones in addition to the performance requirements of mobile phones. For mobile phones with metal shells, the metal surface is often brushed to make directional stripes on the surface of the metal back shell of the mobile phone, so as to increase the texture and appearance of the metal shell. In the existing technology, the abrasive cloth or sandpaper is usually laid flat and then fixed, and the metal back shell is polished back and forth on the abrasive cloth or sandpaper to form a wire drawing effect. However, since the abrasive cloth or sandpaper is very easy to wear and tear, it needs to be replaced continuously, resulting in suspension of production and affe...

AI Technical Summary

Problems solved by technology

However, because the abrasive cloth or sandpaper is extremely easy to wear and tear, it needs to be replaced continuously, resulting in production suspension and affecting production efficiency

Moreover, most of the traditional wire drawing processing of mobile phone cases is realized by manual operation, and the uneven force control of manual wire drawing can easily lead to problems such as the texture layout, uneven texture and inconsistent texture depth of the mobile phone case.

At the same time, when manual wire drawing is used, it is impossible to perform wire drawing operations on curved products or special-shaped products

In addition, manual wire drawing has disadvantages such as high labor intensity, high labor cost, poor wire drawing effect, low product yield and low wire drawing efficiency.
