Description

Technical Field

[0001] The invention relates to the technical field of cold shears, in particular to a shear blade holder adjustment and measurement device for a cold shear. Background Art

[0002] Cold shears are commonly used in the metallurgical industry to trim heads, tails, or cut rolled pieces to length. As a type of shearing machine, cold shears are widely used in metallurgy, aviation, defense, and light industries such as printing. The shear head is a core component of cold shearing equipment, and its precision directly impacts shear quality, equipment life, and production efficiency. Due to long-term exposure to high impact loads and friction, the shear head can deform, wear, or become misaligned, necessitating high-precision measurement technology for inspection and adjustment. The shear head is typically made of high-strength alloy steel (such as 42CrMo), but micro-deformations (such as bending or twisting) can occur after long-term use, affecting shearing accuracy. The quality of a cold shear cut depends on the parallelism, clearance, and alignment of the upper and lower blades. Shear head misalignment (e.g., >0.1mm) can result in burrs, material tearing, or equipment vibration. If wear or deformation of the shear head is not detected promptly, it can lead to cascading damage (such as bearing failure and drive system overload).

[0003] Misalignment or unevenness in the shear blade holder of a cold shearing machine can severely impact equipment performance and shear quality. Misalignment can cause the upper and lower shear blades to misalign, resulting in beveled cuts, increased burrs, or deformation on the sheared surface. This can cause the steel's dimensional accuracy to exceed the ±1mm tolerance and even render the product scrapped. Furthermore, misalignment can disrupt the proper fit of the shear blades, causing localized stress concentrations and accelerating blade edge cracking. This damage is particularly pronounced on high-strength alloy blades with a hardness of HRC58-62. It can also increase abnormal wear on the crankshaft and connecting rod mechanism and bearings, shortening the equipment's service life. Summary of the Invention

By setting the blocking plate 523, it can move in the inner cavity of the limit box 522, so that when the two shear blade holders of the cold shear machine move relative to each other, the blocking plate 523 moves in the inner cavity of the limit box 522 without leaking the airflow.

By providing the blocking block 5210, the second sealing ring 5211, and the second spring 529, the red paint in the inner cavity of the paint storage tube 528 can be adsorbed to prevent the red paint inside from being easily discharged. When a gap is formed between the adsorption box 525 and the shear blade holder of the cold shear machine, the air in the inner cavity of the adsorption box 525 is discharged. Then, under the flow of air, the red paint in the inner cavity of the paint storage tube 528 is drawn out and sprayed onto the outer surface of the cold shear blade holder, achieving the purpose of marking uneven areas.

[0049] Working principle: When in use, the operator inserts the first threaded rod 32 into the hole on the outer surface of the cold shear blade holder, and then rotates the threaded ring 34 until the anti-slip ring 35 and the extrusion ring 33 squeeze the two sides of the cold shear blade holder, completing the effect of positioning the connecting shell 1 on the outer surface of the cold shear blade holder, and at the same time inserts the positioning tube 7 into the hole of the cold shear blade holder, and then rotates the threaded column 8 to tightly connect the track frame 6 to the cold shear blade holder, and then makes the suction cup 416 contact with the outer surface of the cold shear blade holder below, and then rotates the third threaded rod 414 to make the suction cup 416 tightly adsorbed on the outer surface of the cold shear blade holder; after the device is positioned on the outer surface of the cold shear blade holder, start the cold shear, and when the cold shear blade holder moves up and down, the top shell 41 moves downward, thereby squeezing the first telescopic tube 43. During the squeezing process, the air in the inner cavity of the first telescopic tube 43 is compressed, and then The air is discharged from the holes on the outer surface of the air permeable shell 45 and finally discharged into the inner cavity of the second telescopic tube 51 through the exhaust shell 47 and the second one-way valve 48. When the outer surface of the cold shear blade holder is flat, the adsorption box 525 and the rubber ring 527 are in tight contact with the outer surface of the cold shear blade holder, so that the air flow will not be ejected from the gap. At this time, the air in the inner cavity of the second telescopic tube 51 increases, thereby causing the second telescopic tube 51 to extend, causing the adsorption box 525 and the rubber ring 527 to move laterally on the outer surface of the cold shear blade holder and move to the next position. When the outer surface of the cold shear blade holder is uneven, the adsorption box 525 and the rubber ring 527 create a gap with the outer surface of the cold shear blade holder, thereby causing the air in the inner cavity of the second telescopic tube 51 to be ejected from the gap. During this process, the red paint in the inner cavity of the paint storage tube 528 is ejected along with the air flow and sprayed onto the outer surface of the cold shear blade holder, achieving the effect of marking the uneven area.
