Embodiment approach

[0047] The steel wires of the same diameter drawn by 2-3 wet drawing machines are collected on a pay-off I-shaped wheel 101 according to the same drawing speed, so as to ensure that the 2-3 steel wires taken up at the same time are arranged evenly and the take-up The tension is the same, and the I-shaped wheels are unloaded according to the corresponding fixed length; then according to the number of strands of the finished cord, the corresponding number of I-shaped wheels are respectively placed in each prefabricated device 1, and passed through according to the corresponding winding method. Tension adjustment device 102, pre-twisting auxiliary flywheel disc 103, over-twisting device 2; multi-strand yarns are evenly distributed on the thread distribution disc 301, and then meet at the thread gathering nozzle 302, and the thread gathering nozzle 302 is selected according to the specifications of the finished cord And the die 303, the multi-strand wires gathered together enter th...

[0049] Existing product 4×2×0.25HE production

[0050] Put two rounds of heat-treated electroplated brass steel wire with a diameter of 1.48 on two wet drawing machines respectively, and then complete the mold penetration according to the wet drawing process of 1.48-0.25, and pass the steel wire drawn by one of the wet drawing machines through the wire passing wheel And go to the traction wheel of the other wet drawing machine to link the electric control parts of the two wet drawing machines so that the drawing speeds of the two wet drawing machines are consistent, and the combined two steel wires are collected in one pay-off worker 4 such pay-off I-shaped wheels 101 are respectively placed on the I-shaped wheel placement device in the prefabricated device 1, and the steel wire presses figure 1 In the threading method shown, it goes through the pre-twisting secondary flywheel disc 103, the over-twisting assembly 203, to the line distribution disc 301, and then passes through...

Abstract

The invention discloses production equipment of steel cords. The production equipment comprises multiple prefabrication devices, wherein each prefabrication device comprises a pay-off spool with tension control, a tension adjusting device and a pair of auxiliary flywheel discs, multiple first over-twisting devices are arranged on one side of the prefabrication device, each first over-twisting device comprises a front cord passing wheel, a back cord passing wheel and an over-twisting assembly with two over-twisting wheels, a cord collecting device is arranged on the other side of the first over-twisting device and comprises a distributing plate with a cord passing wheel, a cord collecting nozzle, and a main machine is arranged on the other side of the cord collecting device and comprises apair of main flywheel disc, a traction device, a second over-twisting device, a straightener assembly and a take-up device with a cord arranging function. Compared with the prior art, the equipment structure is simplified, the floor area is reduced, noise is reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of steel cord production, in particular to production equipment and a production method for steel cords. Background technique [0002] The existing steel cord products are basically divided into single-strand (layer) structures according to the structure of their steel wires, such as 2 × 1, 3 × 1, 5 × 1, etc.; layered structures such as 3+6, 2+7 , 3+9, 3+9+15, etc., and three types of strand structures such as 3×2, 3×7, 3×4, 4×2, etc. In recent years, with the advancement of steel cord technology, new Variety of steel cords are constantly released, but mainly concentrated in single-strand (layer) structure and layered structure, and the cords of the strand-rope structure are few to very few. The reason is mainly that the strand-cord cord equipment of the prior art High occupancy rate, 3×7×0.20HE, requires 2-3 sets of equipment to produce strand 0720, and then equipped with 1 set of equipment to produce finished produ...
