Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-speed wire rod mill technology, specifically to a sliding guide assembly for the pre-finishing inlet of a high-speed wire rod mill. Background Technology
[0002] The main function of the pre-finishing mill is to pre-shape the material from the roughing and intermediate rolling mills to provide the finishing mill with qualified billets. Therefore, while the rolling force of each stand in this unit is under normal design conditions, when external conditions change, such as uneven temperature of the incoming rolled material, large bends in the incoming rolled material, misalignment of the pre-finishing mill rolling line, or uneven wear of the pre-finishing roll rings, it becomes difficult to control the shape and size of the rolled material head. The impact and wear of the rolled material on the inlet sliding guide assembly are significant, requiring a reliable connection and fastening between the inlet sliding guide assembly and the guide base. The shape and structure of the internal rolling channel of the inlet sliding guide assembly and the fixing method between the inlet sliding guide assemblies are key factors affecting the reliability of the connection between the inlet sliding guide assembly and the guide box. If the fastening force between the inlet sliding guide assembly and the guide box, as well as the outlet sliding guide assembly, is too small, when the pre-finishing rolled material impacts the inlet sliding guide assembly due to bends or other reasons, causing the inlet sliding guide assembly to withdraw or loosen, it will cause damage to the inlet sliding guide assembly and the guide base, leading to an escalation of the accident. Therefore, this utility model provides an inlet sliding guide assembly for the pre-finishing mill of a high-speed wire rod mill to solve the above problems. Utility Model Content

[0027] The inner cavity 3 inside the main body 1 of the entrance sliding guide group has a trumpet structure.
[0028] Nut A72 is threaded onto the first threaded post 71, and nut B74 is threaded onto the second threaded post 75.
[0029] Both the outer ends of the first threaded post 71 and the second threaded post 75 are provided with strip-shaped slots, which are connected to the card at the inner end of the bottom block 6 and the slot 8.

[0033] Working principle:
[0034] 1. Design the external dimensions and length of the inlet sliding guide group reasonably according to the dimensions of the inlet space of each pre-finishing mill stand.
[0035] 2. Determine the specific dimensions of the internal roll pass of the sliding guide group at the pre-finishing mill entrance based on the external shape of each pre-finishing mill stand.
[0036] 3. In order to facilitate the smooth entry of the pre-finishing mill workpiece into the inlet sliding guide group, the front end of the inlet sliding guide group is designed as a trumpet shape. The length and opening of the trumpet shape are determined according to the external dimensions of the incoming workpiece.
[0037] 4. To ensure a secure fit between the two halves of the inlet sliding guide assembly, the two halves are fixedly connected by bosses on each half and bolts and nuts. Then, T-bolts and T-blocks are used to fix the pre-finishing inlet sliding guide assembly to the guide base, thus forming a reliable fastening relationship between the left and right inlet sliding guide halves and the guide base, ensuring the stability of the production process.
[0038] To ensure the strength of the inlet sliding guide assembly, the material of the inlet sliding guide assembly is generally selected as cast iron or cast steel, so as to ensure that it can withstand large impact loads without large deformation or breakage.
