Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of steel strand production equipment, concretely is a wire drawing machine for steel strand production. BACKGROUND

[0002] With the continuous progress of steel strand production technology, the existing steel strand production device has been widely used. However, these products still have some problems in actual use. For example, the existing steel strand production device usually lacks effective temperature control and steel strand fixing mechanism in the wire drawing process, which leads to unstable processing quality and low production efficiency and other problems.

[0003] In order to solve these problems, there have been some attempts, such as improving the cooling system and fixing device to improve the processing quality and production efficiency of steel strand. Although these methods improve the relevant aspects to some extent, they still have limitations, such as uneven cooling effect and unstable fixation.

[0004] Specifically, after searching, a kind of pre-stressed steel strand production process temperature control device with publication number CN217517242U is disclosed, and the publication date is September 30, 2022. The design adopts double-cycle temperature control system and cooling fan, although it can realize the temperature control in the production process of steel strand, but since the opening and closing of its cooling fan depends on manual operation, the degree of automation of temperature control in actual production process is low, it is difficult to meet the needs of continuous production. In addition, the design does not involve the fixation problem of steel strand in the processing process, so the stability of steel strand in the wire drawing process cannot be guaranteed.

[0005] After searching, a kind of pre-stressed steel strand production's fixing device with publication number CN217572569U is disclosed, and the publication date is October 14, 2022. The product adopts multiple fixing mechanisms and spring elastic system, although it can provide stable fixation for steel strand, but since the design of its fixing mechanism is only suitable for steel strand of specific diameter, the adaptability for steel strand of different specifications is poor. In addition, the design does not consider the control of temperature in the wire drawing process, which may affect the processing quality of steel strand due to temperature change.

[0006] The above problems show that the steel strand production device on the market at present is difficult to effectively respond to the new requirements of precise temperature control and stable fixation of steel strand under continuous production. Therefore, the utility model provides a wire drawing machine for steel strand production to overcome these deficiencies and provide a new solution that is more intelligent, efficient and adaptable to changing environment. This wire drawing machine will integrate automatic temperature control and fixing mechanism that adapts to steel strand of various specifications to ensure stable processing temperature and stability and processing quality of steel strand in the wire drawing process during continuous production.
