Straight line structure of the processing of the best choice of wire drawing diesgrinding machine to process, if the use of other forms of grinding machine is relatively poor. This is because:

(1) its grinding is a straight line grinding, which is the most fundamental difference between it and the old grinding machine, and the old grinding machine is the use of imitation form grinding;

(2) it is a kind of machining method, which completely solves the influence of human factors caused by manual grinding;

(3) die angle, radial adjustment is using the indicator to achieve, solved by experience, feel the whole grinding mode, grinding process is more reasonable and accurate.

The working principle of the horizontal milling molding machine is: when the mold is clamped on the head rotating at high speed (1000 ~ 5000r/min), in order to reverse rotation grinding high speed (10000 ~ 40000r/min), and the grinding angle by the reciprocating straight-line motion for grinding of the die hole.

The angle of grinding and grinding molding machine on angle is selected, set according to the die hole angle of wire drawing dies, each part of the die hole diameter is through the radial distance adjusting grinding to achieve. The grinding method, regardless of the shape of the surface of the die hole, the die wall surface of each point can be very evenly throughout the cone grinding, and grinding of the cone can be uniformly grinding to the mold wall on each point, so the grinding cone can be uniformly grinding to die on the wall of each point, so you can make sure the profile die hole is composed of several lines, each line is at the intersection of minimal arc angle and grinding cone is a straight cone, and will not change the original grinding angle. In the 4 regional grinding mold, according to different requirements (such as angle and diameter), radial adjusting grinding feed rate, die hole center line and the center line of the grinding angle and grinding feed, so that you can complete the whole process of mould processing.

Another reason for the mold before the size of each part is not standardized, only the regional parameters are specified, and did not make detailed provisions on how these parameters such as diameter of road, with the length of the how to meet the prescribed requirements, the operator is to grasp their own experience. Therefore, it is necessary to have a complete, systematic and practical operation process of grinding die. The pull wire process of wire drawing dies should be based on the specific circumstances are divided into high carbon and low carbon, dry and wet pull pull, large holes and small die hole, pickling free drawing and drawing, galvanized after pickling and galvanized, back cone,cone,entrance design work according to the specific requirements of the exit cone angle and sizing belt the length (including the parameters to achieve the sizing zone length is determined by the middle value of this parameter with analytic geometry calculation), prefabricated hole diameter.
