The selection method of the crimping wheel of the inverted wire drawing machine
When the inverted wire drawing machine is in normal operation, the wire can be well wound on the large plate, mainly relying on the function of the pressing wheel. The wire pressing wheel tightly presses the wire on the big wheel to ensure that the wire can be wound on the big wheel for a sufficient number of turns. The function of the crimping wheel is very important. Not only the material should be selected, but the size of the crimping wheel should also be appropriate. The inverted wire drawing machine can not only thin the wire, but also draw the wire of circular section into metal products of other sections through a special die. For example, square steel can be obtained by drawing from a circle, and flat steel can be obtained by drawing a circle. When processing ordinary coiled wire, the outer circle of the wire pressing wheel must have a certain taper, so that the steel bar can go down better layer by layer. When processing square steel and flat steel, the outer circumference of the wire pressing wheel cannot be There is a taper. When it is processed into a taper, the outer circle of the wire pressing wheel and the surface of the square steel will not be completely released. When the force is large, the surface of the finished product will be uneven. Therefore, the flat steel, square steel and other surfaces are processed. Flat wire rods When , the outer circle of the pressing wheel should be made into a cylindrical shape.
