Description

Technical Field

[0001] The utility model relates to the technical field of rolling mill shear blade replacement and maintenance auxiliary tools, in particular to a shear blade moving and delivering device. Background Art

[0002] The rolling mill shear blade is an indispensable component in the steel rolling production process, mainly used for precise cutting of steel in the continuous or semi-continuous rolling process. According to different application scenarios and technical requirements, the design and material selection of the rolling mill shear blade have different characteristics and technical considerations. The following is some key information about the rolling mill shear blade:

[0003] 1. Function and application: The shear blades of rolling mill are mainly used to shear the defective parts of the head and tail of wire rods, and to cut to length to ensure the high quality of products. They are widely used in various types of rolling mills such as hot rolling, cold rolling, wire rod, etc.

[0004] 2. Design features: Double-blade shear: This is a common design with two blades arranged opposite to each other, achieving efficient shearing through precise gap control and strong shearing force. Four-bar linkage: Some flying shear devices use a four-bar linkage, which allows the shear blade to move approximately in a plane in the shearing area, perpendicular to the surface of the rolled piece, ensuring a straight shear section. Active shear blade: In wire mills, the design of active shear blades can improve the flexibility and accuracy of shearing and adapt to wires of different sizes.

[0005] 3. Material and heat treatment: The shear blade is usually made of high-quality alloy steel and undergoes a strict heat treatment process to obtain excellent hardness, wear resistance and impact resistance. For example, alloy materials containing elements such as As, S, P, Sr, Cd, Os, etc. are used and undergo specific heat treatment to improve their performance.

[0006] 4. Problems and improvements: Traditional double-bevel shear blades may produce an arched shear surface when shearing aluminum alloy plates, affecting subsequent processing. Therefore, a new composite shear blade and optimized shearing method were developed to solve this problem.

[0007] 5. Maintenance and replacement: Considering that the shear blade is a consumable, regular inspection and replacement are necessary to maintain the cutting quality.

[0008] Modern designs tend to be easy to replace and maintain. The surface of the shear blade is smooth, and people hold it barehanded when moving and transporting. It is easy to slip out of the hand, causing the shear blade to fall and damage the edge, affecting its use. There is a layer of oil film on the surface of the shear blade, which may slip out of the hand and fall and cause injuries. There is no force point for gripping, so it is more laborious to pick up.

[0009] Therefore, there is an urgent need to design a device for moving and delivering the shear blade to solve the problem that the existing shear blade is inconvenient to take and deliver and is easy to fall off during replacement and maintenance, posing a safety hazard. Utility Model Content

[0010] In view of the problems existing in the prior art, the utility model aims to provide a device for moving and delivering shear blades.

[0012] Specifically, two mounting holes are provided in the middle of the shear blade, the position where the fixing column is installed on the fixing plate matches the positions of the two mounting holes, and the diameter of the fixing column is smaller than the inner diameter of the mounting hole.

[0013] Specifically, the fixing plate is installed at the bottom of the portable rack, and the middle part of the portable rack is inclined.

[0014] Specifically, a handle is provided on the upper part of the portable frame, and the center of gravity of the handle and the shear blade are on the same vertical line.

[0015] Specifically, the stop positioning block is arranged opposite to the end of the fixing column, the stop positioning block adopts a circular ring structure, a stop positioning hole is arranged in the middle of the stop positioning block, and the stop passes through the stop positioning hole.

[0016] Specifically, the diameter of the stopper is smaller than the inner diameter of the stopper positioning hole, and a baffle is provided on one side of the stopper, and the baffle is blocked at the outside of the stopper positioning block.

[0017] The utility model has the following beneficial effects:
