Design method for die chain of coarse specification steel wire drawn by double low-power car frame

Abstract

The invention discloses a design method for a die chain of a coarse specification steel wire drawn by a double low-power car frame, the power during the parallel transformation of the double low-powercar frame can be reasonably distributed by the design method, a second car frame is fixed for fewer gates, certain gates are allocated by a first car frame, the efficiency of a high-power wire drawing machine is realized, the requirements of customers on the preparation of the coarse specification steel wire are met, the required adjusted rotating speed of the first car frame is accurately calculated according to parameters such as the diameter of each tower wheel, the diameter of a pulley, and the like, and the die chain design method can calculate the gate distribution and speed adjustmentof the two parallel machines easily and accurately so as to lay a foundation for preparing the high-quality coarse specification steel wire.

Description

technical field [0001] The invention relates to a method for designing a mold chain for drawing steel wire, in particular to a method for designing a mold chain for drawing thick-gauge steel wire with double low-power lathes. Background technique [0002] The existing steel wire drawing machine is a low-power machine. When drawing thick-gauge steel wire, the current low-power wire drawing machine cannot meet its requirements. At present, two low-power machines are set in parallel for rough The scheme of standard steel wire drawing, but there are certain difficulties in the design of the mold chain. The number of drawing modules used in the existing drawing car is 23, the first group is 10 passes, and the second group is 13 passes; such as 2.20~0.60; According to the method that the compression rate of the mold chain is greater than that of the machine, the actual mold chain can only have 15 passes. Currently, two sets of 11KW are used (the first set of tower wheels of the fi...

[0002] The existing steel wire drawing machine is a low-power machine. When drawing thick-gauge steel wire, the current low-power wire drawing machine cannot meet its requirements. At present, two low-power machines are set in parallel for rough The scheme of standard steel wire drawing, but there are certain difficulties in the design of the mold chain. The number of drawing modules used in the existing drawing car is 23, the first group is 10 passes, and the second group is 13 passes; such as 2.20~0.60; According to the method that the compression rate of the mold chain is greater than that of the machine, the actual mold chain can only have 15 passes. Currently, two sets of 11KW are used (the first set of tower wheels of the first car and the second set of the second car are used) The turret, electrical communication and parallel connection) equipment cannot be produced. The first car has less power sharing due to the small number of modules. How to carry out reasonable power distribution is worth studying.
