Description

Technical Field

[0001] This utility model belongs to the technical field of hoisting auxiliary equipment, and specifically relates to an auxiliary tool for assembling the shear blade of a hot-rolled bar cold shearing machine. Background Technology

[0002] When installing the shear blades of a traditional hot-rolled bar cold shearing machine, due to the machine's structural design, the replacement window is small, making it impossible for the overhead crane to directly lift the blades into the machine base. This requires both overhead crane lifting and manual handling, resulting in low installation efficiency and posing a safety hazard as it increases the risk of injury to personnel during handling. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an auxiliary tool for assembling the shear blade of a hot-rolled bar cold shearing machine, which solves the problem that in the prior art, the shear blade of the cold shearing machine needs to be manually handled when assembling with the base, which poses a safety hazard.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An auxiliary tool for assembling the shear blade of a hot-rolled bar cold shearing machine includes a gate-shaped frame, a sleeve fixedly connected to the top of the gate-shaped frame, a push rod provided inside the sleeve, a crossbeam, side plates connected to both sides of the crossbeam, square positioning holes symmetrically opened on the side plates, strip positioning blocks passing through the two square positioning holes, and the two ends of the strip positioning blocks extending out from both sides of the gate-shaped frame.

[0006] The opening width of the door frame is 2-5mm wider than the width of the shear blade.

[0007] The sleeve is installed along the centerline of the crossbeam.

[0008] The inner diameter of the sleeve is 2-5 mm larger than the diameter of the push rod.

[0009] The length of the push rod exceeds the length of the shear blade.

[0010] The cross-sectional dimensions of the strip positioning block are matched with the square positioning hole, and the length of the diagonal of the cross-section is less than the diameter of the shearing hole.

[0011] The push rod is made of steel.

[0012] Compared with existing technologies, the beneficial effects of this utility model are:

[0013] This invention assists in the assembly of shear blades in a hot-rolled bar cold shearing machine by using a lever principle to maintain the balance of the shear blades during installation. A push rod then delivers the shear blades into the blade base, completing the installation. This eliminates the need for manual handling during blade installation, making it safer, more labor-saving, and improving installation efficiency. Attached Figure Description

[0018] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0019] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] like Figures 1-3 An auxiliary tool for assembling the shear blade of a hot-rolled bar cold shearing machine includes a gate-shaped frame 1, a sleeve 2 fixedly connected to the top of the gate-shaped frame 1, a push rod 3 provided inside the sleeve 2, a crossbeam 11, side plates 12 connected to both sides of the crossbeam 11, square positioning holes 13 symmetrically opened on the two side plates 12, strip positioning blocks 14 passing through the two square positioning holes 13, and the two ends of the strip positioning blocks 14 extending out of the two sides of the gate-shaped frame 1.

[0021] The opening width of the gate-shaped frame 1 is 2-5mm wider than the width of the scissor blade 4. The shape of the gate-shaped frame 1 matches that of the scissor blade 4, which can prevent the scissor blade 4 from tipping over. The scissor blade 4 is easy to install and its wobbling within the opening is reduced, ensuring that the scissor blade 4 is well secured.

[0022] The sleeve 2 is arranged along the centerline of the crossbeam 11.

[0023] The inner diameter of the sleeve 2 is 2-5mm larger than the diameter of the push rod 3. The diameter of the push rod 3 is slightly smaller than the inner diameter of the sleeve 2. This ensures that the push rod 3 can be inserted into the sleeve 2, and also reduces the shaking of the push rod 3 inside the sleeve 2, making it more stable and safe when prying and pushing.

[0024] The length of the push rod 3 exceeds the length of the shear blade.

[0025] The cross-sectional dimensions of the strip-shaped positioning block 14 are matched with the square positioning hole 13, and the length of the diagonal of the cross-section is less than the diameter of the shear blade hole 41. Both the strip-shaped positioning block 14 and the square positioning hole 13 are square to prevent mutual rotation and ensure safety and stability. The dimensions of the square positioning hole 13 and the strip-shaped positioning block 14 are set according to the dimensions of the shear blade hole 41. The square positioning hole 13 can pass through the shear blade hole 41, which is easy to manufacture and simple to install.

[0026] The push rod 3 is made of steel.

[0027] How to use:

[0028] When assembling the shear blade 4 of the hot-rolled bar cold shear with the shear blade base, a lifting device 5 is inserted into the shear blade holes 41 at both ends of the shear blade 4, and the shear blade is lifted by a crane to the vicinity of the shear blade base. The portal frame 1 is placed from above into the middle of the shear blade 4, so that the shear blade 4 enters the opening of the portal frame 1. The square positioning hole 13 is aligned with the shear blade hole 41. The strip positioning block 14 is inserted from one side of the square positioning hole 13, passes through the shear blade hole 41, and exits from the other side of the square positioning hole 13 to fix the shear blade 4.

[0029] Insert the push rod 3 into the sleeve 2 and press it down. The push rod 3 uses one end of the shear blade 4 as a fulcrum to pry up the shear blade 4, keeping it balanced. Use the lifting tool 5 at the fulcrum end and auxiliary tools to maintain the balance of the shear blade 4. Then remove the lifting tool 5 from the other end of the shear blade 4. Next, push the push rod 3, and with the help of a crane, send the shear blade 4 into the shear blade base assembly position. Finally, remove the push rod 3 and remove the strip positioning block 14 and the gate frame 1. The installation of the shear blade 4 is complete. During installation, no manual handling is required, making it safer, less strenuous, and more efficient.
