specific Embodiment

[0019] A method for prolonging the service life of a wire drawing die, comprising the following steps:

[0020] 1) Number the molds between different passes: number 1, 2, 3, ..., N on the molds between each pass in sequence; N is determined according to the actual drawing pass requirements;

[0021] 2) Numbering the molds of the same pass: the molds of the same pass are numbered (1), (2), (3), ..., (n) according to the size of the mold aperture; (n) according to the actual production The number of heads of the wire drawing die is determined as (8) or (16) or (24) or (32);

[0022] 3) Mold installation: During the mold installation process, the molds of different passes are installed in sequence according to the number, and the aperture diameter of the same pass mold gradually decreases or increases sequentially from the inside to the outside;

[0023] 4) Segmented maintenance: return to the factory for maintenance of several passes with similar mileage of the mold; the mileag...

Embodiment 1

[0026] A method for prolonging the service life of a wire drawing die, comprising the following steps:

[0027] 1) Number the molds between different passes: number 1, 2, 3, ..., 15 on the molds between each pass in sequence;

[0028] 2) Number the molds of the same pass: the molds of the same pass are numbered (1), (2), (3), ..., (8) in sequence according to the size of the mold aperture;

[0029] 3) Mold installation: During the mold installation process, the molds of different passes are installed in sequence according to the number, and the aperture diameter of the same pass mold gradually decreases or increases sequentially from the inside to the outside;

[0030] 4) Segmented maintenance: Return to the factory for maintenance in several passes with similar mileage of the mold; the mileage of the mold is calculated based on the product specification with the highest output of the current machine.

[0031] When using this embodiment, the molds between different passes and...

Abstract

The invention relates to a method for prolonging the service life of a wire drawing die. The method comprises four steps of numbering dies in different passes, numbering dies in the same pass, installing the dies and carrying out segmented maintenance, wherein the numbering step is used for respectively numbering the dies in different passes and the same pass by different numbers; during a die installing process, the dies in different passes are installed according to the numbers, and the pore diameters of the dies in the same pass are sequentially reduced or sequentially increased from insideto outside; the segmented maintenance is used for carrying out unified return-to-factory maintenance on several passes of dies of which the passed mileages are approximate. The method disclosed by the invention is capable of prolonging the service life of the wire drawing die, reducing the time required for replacing the dies and reducing the impact of disconnection on capacity.

Description

technical field [0001] The invention relates to a method, which belongs to the field of automobile electric wire production, more specifically, the invention relates to a method for prolonging the service life of a wire drawing die. Background technique [0002] In the production process of automobile wires, the multi-head wire drawing process is a very important part. It is the last process of copper processing, and at the same time determines the production capacity distribution of the entire processing process. Therefore, extending the service life of the wire drawing die will help improve The final capacity of the product. At present, the replacement cycle of wire drawing dies is determined according to the experience of each factory. A brand new die needs to be returned to the factory for maintenance after 6 months of use. After maintenance, it can be used again for 3 months. The conditions for determining the need for maintenance are: Exclusion Due to the influence of...
