Drawing die matching is the work of determining the drawing pass, drawing die hole size and shape according to the blank size and metal wire size during wire drawing, also called drawing procedure or drawing route formulation. Can be divided into single-pass wire drawing die and multi-pass wire drawing die. The main steps of the drawing die include the following steps: selecting the blank; determining the number of intermediate annealing; determining the extension coefficient of the drawing pass and the distribution pass; checking the die matching. The article refers to the two cases of circular cross-section metal drawing and irregular-section metal drawing, specific Introduce the drawing die matching steps and calculation methods. Drawing die

Sliding wire drawing machine tool matching principle and tool matching calculation: wire drawing tool matching refers to the method of selecting each drawing wire mold in our drawing process. There are two main points of reasonable die matching. One is mechanical; the sliding wire drawing machine has its fixed wire wheel speed ratio. According to the example of the actual wire drawing machine die matching calculation, the correlation between pulling 7.2mm copper rod and 1.6mm copper wire is calculated. data. Drawing die
