Detailed Description

The invention is described in detail below with reference to the figures and specific embodiments.

Example 1

The rolling shear cutter fully utilizes the metal property of the alloy steel outer ring of the isolation ring, has a good vibration transmission effect, and particularly can transmit vibration and effectively eliminate vibration when the rolling shear blade is in contact with the alloy steel outer ring due to the tiny vibration of the rolling shear blade, so that the precision of rolling shear is improved; when the elastic component is pressed down, the elastic component has certain deformation, and the normal use of the cutter is not influenced.

When the aluminum strip is cut by the cutting edge, the side clearance and the overlapping amount between the upper cutter head and the lower cutter head are different due to different thicknesses, components and performances of the aluminum strip. In actual production, due to the influence of side gaps and overlapping amount, the edge of the cut aluminum strip has the defects of edge warping and burr, and the quality of the cut product is influenced. For some aluminum products with specific requirements, the aluminum products need to be cut and then trimmed by a special trimming device, namely, an off-line shaping device needs to be used for trimming the edge of the cut aluminum strip.

For example, the maximum stress of a certain aluminum strip is 244.79MPa, the fine aluminum strip produced by the prior art roller shear tool has burr sharp corners at the edges of the fine aluminum strip, when the maximum stress is larger than the tensile strength, the aluminum strip breaks along the sharp corners, and the aluminium strip breaking positions start to crack along the root sharp corners and finally break at the roots after being proved by a plurality of times of aluminum strip tensile tests. By adopting the rolling shear tool of the embodiment, the edge of the thin aluminum strip is flat and smooth, no burr sharp corner exists, and when the maximum stress is greater than the tensile strength, the probability of the aluminum strip breaking is reduced by 3-5% compared with the current probability by multiple aluminum strip tensile test results, so that the rolling shear tool has a good application prospect.

In this embodiment, the elastic member 320 is a compression spring 323, a rubber ring 322 or an air bag 321. The rubber ring 322 is connected with the alloy steel inner ring 310 and the alloy steel outer ring 330 through metal glue. When the elastic component 320 is preferably an air bag 321, a plurality of bases 311 are annularly arranged on the alloy steel inner ring 310, and the air bag 321 is fixed on the bases 311 through a pressing plate 312 and screws 313. An air nozzle (not labeled) is disposed at one side of the air bag 321, and air inlet and air outlet can be realized through the air nozzle.

In the using process, because the air bag 321 has the possibility of air leakage, a limit block 314 is arranged inside the air bag 321, and the limit block 314 is fixed on the base 311; the limiting block 314 is a nitrile rubber block or a metal rubber block, and plays a certain supporting role through the limiting of the limiting block 314.

Considering the special material of the air bag 321, the air bag 321 cannot be directly and fixedly connected with the alloy steel outer ring 330, so the top of the air bag 321 is fixed on the alloy steel block 324 through a pressing plate and a screw (none of which are labeled in the figures), and the alloy steel block 324 abuts against the inner side of the alloy steel outer ring 330 and is bonded and connected by metal glue. During installation, the air cells 321 are inflated last, and the inflation amount of each air cell 321 is kept substantially consistent, so that the concentric arrangement of the alloy steel outer ring 330 and the alloy steel inner ring 310 is ensured.

According to the structure, in order to facilitate installation and replacement, at least three magnetic attraction elements are arranged on the alloy steel inner ring 310. When the split type roller shear blade needs to be replaced, the split type roller shear blade only needs to be taken down, a new split type roller shear blade is sleeved on the cutter shaft, the magnetic suction elements on the two adjacent isolating rings can adsorb the roller shear blade from two sides, an operator can quickly fasten the fastening screw to complete replacement, and troubles in installation are eliminated.

In addition, as is known, for pole pieces or material belts conveyed in a long distance, it is difficult to ensure that errors of the advancing offset of the pole pieces are contained in a working range and cut by cutting equipment, so that the use has great limitation, and defective products are easily generated by cutting. The inventor also surprisingly finds that the rolling shear tool for the fine aluminum strip of the embodiment is not easy to shift in the rolling shear process and has high rolling shear precision in the use process. It can be easily found that the elastic component of the rolling shear cutter of the embodiment has the function of automatically rectifying deviation, so that the deviation of the wide aluminum strip in the rolling shear process is avoided.
