Description

Technical Field

[0001] The utility model relates to the technical field of metal wire drawing, in particular to an angle-adjustable metal plate wire drawing device. Background Art

[0002] Metal sheet wire drawing is an important processing method in the field of metal processing, which is used to prepare metal sheets and give them specific surface textures and properties. This process generally includes the following steps: 1. Surface treatment: The metal sheet is cleaned, polished and other treatments to remove surface oxides and impurities in preparation for the next step of processing; 2. Wire drawing: The metal sheet is drawn by a wire drawing machine or a rolling machine, and the metal sheet is drawn into the desired texture and surface effect by mechanical force. This process can use different molds and equipment to achieve different lines and textures; 3. Surface treatment: The drawn metal sheet can be cleaned, pickled, polished and other treatments again to enhance its surface finish and overall texture. The products after metal sheet wire drawing are often used in architectural decoration, furniture manufacturing, electronic products, automotive accessories and other fields, and have the characteristics of beauty, wear resistance and corrosion resistance.

[0003] In the prior art, the drawing rollers in the metal plate drawing machines are mostly fixed structures. When it is necessary to perform inclined drawing on the metal plate, the current method is to use a variety of pads to install the metal plate at an angle. However, due to the limited operating space on the conveyor table, the installation of the metal plate is more complicated. At the same time, when diamond drawing is required, the metal plate needs to be disassembled and installed again, and the processing efficiency is low. Therefore, we propose an angle-adjustable metal plate drawing device to solve the above problems. Utility Model Content
