Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a short-process rolling equipment. Background Technology

[0002] In traditional short-process rolling mills, the stability of continuous material delivery directly affects the rolling quality. Existing short-process rolling mills are prone to deviation, wrinkling, or even strip breakage due to sudden tension changes when the material enters and exits the mill. Furthermore, traditional roll sets are rigidly fixed and cannot absorb instantaneous impacts during the rolling process. At the same time, multi-pass rolling requires the independent arrangement of multiple pieces of equipment, resulting in a long process and large footprint. In view of this, existing technologies may already have solutions to the above problems, but this application aims to provide an alternative or replacement technical solution. Utility Model Content

[0011] Beneficial effects

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example: Please refer to Figure 1-3 A short-process rolling equipment includes a base plate 1 and two rolling mill bodies 2. The two rolling mill bodies 2 are respectively installed on one side of the upper end of the base plate 1, and two traction buffer structures are installed on the other side of the upper end of the base plate 1. The two traction buffer structures are respectively located on one side of the two rolling mill bodies 2.

[0019] Both traction buffer structures include: a linear module 3, a vertical plate 4, a sliding plate 5, a limiting plate 6, a spring 7, a fixed roller shaft 8, and a clamping assembly;

[0020] The linear module 3 is fixedly installed on one side of the upper end of the base plate 1, the vertical plate 4 is fixedly installed above the drive end of the linear module 3, the sliding plate 5 moves laterally through the upper end of the vertical plate 4, the limiting plate 6 is fixedly installed on one side of the sliding plate 5, one end of the spring 7 is connected to the side wall of the limiting plate 6, and the other end is connected to the side wall of the vertical plate 4, the fixed roller shaft 8 is installed on one side of the upper end of the sliding plate 5 through the bearing, and the clamping assembly is fixedly installed on the top of the vertical plate 4.

[0021] When rolling strip metal, the operator first moves the device to the designated position, supports it with the base plate 1, and connects it to the designated control system. According to the rolling requirements, the working distance and rotation speed of the two rolling mill bodies 2 are adjusted to ensure uniform material conveying. Then, the metal undergoes preliminary rolling through one of the rolling mill bodies 2. After preliminary rolling, the metal is guided by a designated traction device operated by the operator and placed between the fixed roller shaft 8 and the clamping assembly. Subsequently, the clamping assembly, in cooperation with the fixed roller shaft 8, clamps and guides the metal wire. One end of the metal wire passing through the traction buffer structure is embedded into the mill body 2 on the other side for further rolling. During the rolling process, in order to ensure the tension of the metal wire, the linear module 3 can be adjusted according to the tightness to change the distance between the vertical plate 4 and the mill body 2. The sliding plate 5 cooperates with the spring 7. When the tension of the metal wire is large, the sliding plate 5 can move towards the mill body 2 within the vertical plate 4 and compress the spring 7 to buffer the metal wire and prevent it from breaking. When the tension of the metal wire decreases, the sliding plate 5 can be reset by the reset action of the spring 7 to ensure the tension of the metal wire.

[0022] In the specific implementation process, the clamping assembly includes: a slide 9, an electric push rod 10, a sliding block 11, and a movable roller shaft 12;

[0023] The slide 9 is fixedly installed on the top of the vertical plate 4, the electric push rod 10 is fixedly installed on one side of the slide 9, the sliding block 11 is movably embedded in the slide 9, and one end is connected to the telescopic end of the electric push rod 10. The movable roller shaft 12 is installed on the top of the sliding block 11 through a bearing.

[0024] When guiding and conveying the pre-rolled metal wire, the electric push rod 10 can be used to push the sliding block 11 to one side in the chute 9 until the side of the movable roller 12 contacts the metal wire. The metal wire is guided by the movable roller 12 and the several guide grooves 13 at the upper end of the fixed roller 8.

[0025] In the specific implementation process, guide grooves 13 are uniformly machined on the upper ends of the movable roller shaft 12 and the fixed roller shaft 8, and bidirectional constraint materials are used to prevent deviation.

[0026] In the specific implementation process, the linear module 3 is a linear screw module, which precisely adjusts the traction position and works with the buffer mechanism to maintain constant tension conveying.

[0027] In practice, the two rolling mill bodies 2 are installed in opposite directions, supporting unidirectional continuous multi-pass rolling and reducing the length of the equipment.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
