The specific embodiment
As Fig. 1, shown in Figure 3, present embodiment comprises workbench 6, admission machine 5, several wire drawing dies 4, several electronic speed governing swift 2 and several tension regulators 3, wherein, described each wire drawing die is provided with tube reducing hole 10, the silk material entry and exit at two ends, tube reducing hole are bell 9, silk material arrival end place at each wire drawing die is provided with solid lubrication container 11, simultaneously, mould at described each wire drawing die is provided with cooling pipe 7 (as shown in Figure 3) on one's body, cooling pipe two ends be connected with automatic circulating cooling system (not drawing among the figure).
Again as shown in Figure 1, each wire drawing die 4 is that benchmark is arranged in order and is fixed on the workbench 6 with the center line in tube reducing hole 10, the aperture in the tube reducing hole of each wire drawing die reduces successively gradually, electronic speed governing swift 2 is located between each wire drawing die 4, and be fixed on the workbench 6, tension regulator 3 is located on each electronic speed governing swift 2 side.As shown in Figure 2, tension regulator 3 is slidingly connected with workbench 6, tension regulator 3 lower ends are connected with spring 8 one ends on glide direction, spring 8 other ends are fixedly connected on the workbench 6, silk material 1 is after twining the 3-5 road on the electronic speed governing swift 2, again tension regulator 3 around on together, the electronic speed governing swift 2 of wraparound enters next group wire drawing die more then.The silk material twines on the electronic speed governing swift of next group and tension regulator more equally, enters next group wire drawing die after the winding, until silk material finished product through admission machine 5 take-up one-tenth dishes.
Since the epidermis of powder cored filament material is thin, intensity is lower and drawing process in produce tangible work hardening (powder cored filament material in drawing process, do not allow to anneal eliminate work hardening), the fracture of wire phenomenon often appears, simultaneously, drawing is fast joined not goodly because of electronic speed governing swift speed, makes the fracture of wire problem even more serious.Therefore, in order to guarantee the smooth and easy of wire drawing, the silk material is in the state of tensioning all the time in the maintenance drawing process, prevent a material fracture of wire, the speed of adjacent electronic speed governing swift is joined and can be determined according to tube reducing basic principle, second flow amount principle, drum diameter, finished silk diameter, the predetermined finished silk speed of drawing process, between them to join a relation as follows:
