Die Matching Guidelines - Four Steps of Drawing Die Matching and Calculation Method of Key Data

Summary: Wire drawing die matching is the work of determining drawing pass, die hole size and shape according to blank size and wire size during wire drawing. It is also called drawing procedure or drawing route formulation. It can be divided into single-pass drawing die and multi-pass drawing die. The main steps of drawing die include the following four steps: 1. Selecting blanks; 2. Determining the number of intermediate annealing; 3. Determining the number of drawing passes and the elongation coefficient of distribution passes; 4. Calibration of die matching. This paper introduces the steps and calculation methods of wire matching for circular and special section metal drawing.

Mould matching principle and calculation example of sliding wire drawing machine

Summary: Wire drawing die matching refers to the method of selecting each drawing die in our drawing process. There are two main points in reasonable die matching: one is machinery; the sliding wire drawing machine has its fixed pulling wheel speed ratio. The correlation number of 7.2mm copper rod to 1.6mm copper wire is calculated by calculating the die matching example of the real wire drawing machine.

Uses of various drawing dies. Detailed classification

See how you classify it? The purpose of drawing dies is to reduce the material to be drawn.

According to size: micro-hole drawing die (inner hole size below 0.2), conventional drawing die.

According to the material of wire drawing die: diamond drawing die (natural diamond and artificial diamond, also known as polycrystalline drawing die), generally used for drawing small size wire and cable; carbide drawing die (YG3, YG6, YG8, YG10 and many other brands), mainly drawing large specifications of steel, copper, aluminum, and other products.

According to the materials and products drawn, they can be divided into ordinary drawing die, aluminium clad steel drawing die, prestressing steel wire drawing die, wire rope drawing die, steel cord drawing die, welding wire drawing die, welding rod drawing die, wire drawing die and so on. After using tungsten carbide steel wire drawing die for a period of time, its internal parts will gradually wear out and be damaged, resulting in the reduction of working performance and accuracy of the carbide wire drawing die. Due to carelessness of operators and improper maintenance and use, the tungsten steel wire drawing die will be damaged or the product quality will decline, and even cause shutdown. How to eliminate and avoid these failures? The number of cemented carbide die fitters is required to master the relevant die repair technology, so that failure can occur at any time, can be handled and repaired at any time, so that it can resume normal use as far as possible, and has given full play to the maximum potential of the die.
