Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of composite roll preparation technology, and more specifically to a composite roll preparation anti-deformation device. Background Technology
[0002] Composite rolls refer to rolls whose outer layer, core, and neck are made of two or more materials. They are generally composed of a core and an outer layer. The core usually requires good strength and toughness to withstand the pressure and impact during the rolling process, while the outer layer needs to have high hardness, high wear resistance, and good thermal fatigue resistance to ensure the service life of the roll and the quality of the rolled products.
[0003] When welding the core and outer layer of existing composite rolls, the composite rolls are usually composed of different materials with different physical properties such as thermal expansion coefficients. During the welding process, uneven heating and cooling can cause large welding stress at the joint of different materials, which can lead to roll deformation, affect the dimensional accuracy and surface quality of the roll, increase the difficulty of subsequent processing, and in severe cases, may render the roll unusable. In addition, when welding existing composite rolls, traditional clamping devices cannot effectively adjust the forces that counteract the deformation of the roll, which may even damage the clamping device during the deformation process.
[0004] A search revealed Chinese Patent Publication No. CN202021994077.2, which discloses an anti-bending support mechanism for a rolling mill roll. The support mechanism includes a bearing housing and a roll support assembly. Both ends of the rolling mill roll are rotatably mounted in the bearing housing via bearings. An installation space is formed between the bearing housing and the rolling mill roll. Multiple roll support assemblies are arranged in the installation space along the axial direction of the rolling mill roll. A rolling arc surface is formed on the roll support assembly, and the rolling arc surface is fitted to the surface of the rolling mill roll.
[0005] In the aforementioned patent, the support mechanism prevents the roll from bending by cooperating the first inclined surface on the height adjustment block with the second inclined surface at the bottom of the support base to adjust the height of the support block. However, when the height adjustment block moves inward, it will squeeze the support base, causing the support base to drive the guide block to make a small displacement. This will cause the roll receiving groove to come into contact with the surface of the roll, thus squeezing the roll. This will cause the side wall of the roll receiving groove to exert tension on the surface of the roll, resulting in the roll surface bending. Utility Model Content
[0006] The purpose of this invention is to provide a device for preventing deformation during the preparation of composite rolls. In this structure, the composite roll to be welded is placed between two clamping components to ensure the stability of the composite roll during welding. During the welding process, when the roll deforms due to uneven heating or other factors, the clamping components are adjusted by an electric push cylinder to generate a force opposite to the direction of roll deformation. This effectively ensures that the roll does not undergo significant deformation during the preparation process, thus solving the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A composite roll manufacturing anti-deformation device includes two clamping assemblies with the same structure; the clamping assembly includes a first movable frame and a second movable frame; both the first movable frame and the second movable frame have a protruding strip integrally provided inside; the protruding strip is semi-circular; wherein, the top of the second movable frame has two inserts integrally provided; the top of the first movable frame has an insertion hole for easy insertion of the inserts.

[0014] As a further technical solution of this utility model, one end of the second lead screw is fixedly installed with the drive motor; the second lead screw is a bidirectional lead screw.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In this invention, the composite roll to be welded is placed between two clamping components during use. A stepper motor drives the first lead screw to rotate, causing the first and second movable frames to move in the same direction. This ensures that the protrusions inside the first and second movable frames cooperate with the bearings at the ends of the composite roll. The two clamping components effectively ensure the stability of the composite roll during the welding process.
[0017] In this invention, during the welding process, when the composite roll deforms, the corresponding first and second movable frames are moved by the adjustment components at the bottom of the clamping assembly, thereby generating a force opposite to the deformation of the composite roll. This effectively reduces the deformation of the composite roll and ensures the manufacturing quality of the composite roll.
[0018] In this invention, the movement of the moving component is achieved by driving the second lead screw through a drive motor. The moving component adjusts the distance between the two clamping components through an adjustment component, which can effectively clamp composite rolls of different sizes to meet different manufacturing needs.
