Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-speed wire production lines in the metallurgical industry, in particular to a roller axial misalignment adjustment mechanical arm for preventing wire stripping. Background Art
[0002] High-speed wire rod mills are generally designed for rough rolling as alternating horizontal and vertical mills, typically using ductile iron or cast steel rolls. Their external dimensions must meet on-site use requirements, and their machining accuracy must meet the design accuracy requirements of the drawings. Rollers are the most important production tools and primary components of high-speed wire rod mills. During the rolling process, the rolls come into direct contact with the workpiece and, under certain rolling conditions, plastically deform the workpiece, ultimately achieving a product shape and dimensional accuracy that meets standard requirements. Roller operating conditions are extremely harsh, so the roll's design strength and material, as well as its online layout, installation, and maintenance, directly impact its service life and condition. The basic roll structure is divided into three parts: the roll body, roll diameter, and roll head.
[0003] The existing adjustment mechanism structure is relatively simple. When axial movement is performed, axial roll misalignment will occur between the roller and a fixed roller, and movement will also occur, which will make the size unable to be fixed, thereby making the device unstable. Therefore, the present invention provides an anti-wire-stripping roller axial roll misalignment adjustment mechanical arm to solve the above problems. Utility Model Content
[0004] The purpose of the present utility model is to provide a roller axial misalignment adjustment mechanical arm that prevents wire stripping, so as to solve the problem that the existing adjustment mechanism structure in the above-mentioned background technology is relatively simple, and when axial movement is performed, axial roller misalignment will occur between the roller and a fixed roller, and movement will also occur, thereby making it impossible to fix the size and making the device unstable.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a roller axial misalignment adjustment mechanical arm for preventing wire stripping, comprising:
[0006] A base, wherein an adjustment arm of an integrated structure is provided on the right side of the middle position of the upper end of the base, and a pin shaft hole with a front-to-back penetrating structure is opened at the upper end of the adjustment arm, and a pin shaft installed in the pin shaft hole is used to connect the first pull rod;
[0007] An adjusting rod is installed at the right end of the first pull rod, and a second pull rod is installed at the right end of the adjusting rod. Limiting nuts are installed on both the first pull rod and the second pull rod.
[0008] Preferably, as a preferred embodiment of the present invention, a through hole is provided at the rear end of the pin shaft, and a limiting iron bar is provided in the through hole.
[0009] Preferably, as a preferred embodiment of the present invention, the outer ends of the first pull rod and the second pull rod are both provided with ear shafts.
[0010] Preferably, as a preferred embodiment of the present invention, the first pull rod and the second pull rod have the same structure.
[0011] Preferably, as a preferred embodiment of the present invention, the screws arranged on the first pull rod and the second pull rod are not full-size, and the straight rods of the first pull rod and the second pull rod close to the ear axis are smooth structures.
[0012] Preferably, as a preferred embodiment of the present invention, the outer end diameter of the ear shaft is larger than the aperture of the pin shaft hole.
[0013] Preferably, as a preferred embodiment of the present invention, the adjustment rod is a rectangular structure.
[0014] Preferably, as a preferred embodiment of the present invention, the material of the entire arm is 45# cast steel.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. In the present invention, by using a wrench to rotate the adjusting rod, the threaded portions of the first and second pull rods enter (or exit) the adjusting rod, thereby shortening (or lengthening) the overall length of the combination of the first and second pull rods and the adjusting rod, thereby driving the adjusting arm and the roller assembled in the adjusting arm to move.
[0017] 2. In the present invention, the direction of moving the rollers can be adjusted to meet the needs of the production site by rotating the adjustment rod, thereby eliminating the roller misalignment between the two rollers.
[0018] 3. In the present invention, the specific size of the adjusting arm of the roller axial offset adjustment mechanism can be designed and selected according to the equipment needs of the production enterprise. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example: Figure 1-3 , the utility model provides a technical solution: including:
[0027] A base 1 is provided with an integrated adjustment arm 2 at the right side of the middle position of the upper end of the base 1. A pin hole with a front-to-back through-structure is opened at the upper end of the adjustment arm 2. A pin 3 installed in the pin hole is used to connect to the first pull rod 4;
[0028] An adjusting rod 5 is installed at the right end of the first pull rod 4 , and a second pull rod 6 is installed at the right end of the adjusting rod 5 . Limiting nuts 9 are installed on both the first pull rod 4 and the second pull rod 6 .
[0029] A through hole is formed at the rear end of the pin shaft 3, and a limiting iron bar 7 is provided in the through hole.
[0030] The outer ends of the first pull rod 4 and the second pull rod 6 are both provided with trunnions 8 .
[0031] The first pull rod 4 and the second pull rod 6 have the same structure.
[0032] The screws arranged on the first pull rod 4 and the second pull rod 6 are not full-size, and the straight rods of the first pull rod 4 and the second pull rod 6 close to the ear shaft 8 are smooth structures.
[0033] The outer end diameter of the ear shaft 8 is larger than the hole diameter of the pin shaft hole.
[0034] The adjusting rod 5 is a rectangular structure.
[0035] The material of the entire arm 2 is 45# cast steel.
[0036] Working Principle: The main function of the axial roll misalignment adjustment mechanism's adjustment arm is to connect the adjustment rod and the roll bearing seat. One end of the axial roll misalignment adjustment mechanism's adjustment arm is fixed to the adjustment mechanism base via a pin and bolt, while the other end is connected to the adjustment link to form an adjustment mechanism. During production, the axial movement of a single roll is adjusted by contracting or releasing the axial roll misalignment adjustment link of the axial adjustment mechanism, ensuring that the axial roll misalignment between the roll and the other fixed roll is eliminated. At the same time, the fixed roll does not move during production, thereby ensuring the standardization of the size and shape of the red billet during production, achieving stable production and reducing spare parts consumption.
