Example 1

1-2, the embodiment provides a thick material shearing tool, which comprises an upper cutter shaft 101 and a lower cutter shaft 102, wherein a plurality of upper cutters 111 are arranged on the upper cutter shaft 101, a plurality of lower cutters 112 are arranged on the lower cutter shaft 102, the upper cutters 111 and the lower cutters 112 are staggered, one side or two sides of the upper cutters 111 and the lower cutters 112 are provided with distance sleeves 103, and a plurality of distance sleeves 104 are arranged between the distance sleeves 103; the opposite surfaces of the upper cutter 111 and the lower cutter 112 are respectively provided with a bevel, and the bevel angles of the bevel are mutually matched; the bevel angle is 3 when cutting 4-5 mm thick material and 4-5 when cutting 5-7 mm thick material.

According to the thick material shearing tool, thick material shearing is realized by improving the oblique angle of the oblique openings of the upper cutter 111 and the lower cutter 112, and the problem of large thickness change of sheared materials is realized by changing the shearing geometric angle.

The thickness of the existing aluminum strip thick slitting machine is required to be cut according to the design: the width of the aluminum strip slitting machine is 0.5-5 mm, the narrowest width of the aluminum strip slitting machine is not less than 80mm, the shearing thickness is required to be developed from 5mm to 10mm due to the development of the aluminum wafer plate market in the later use process, and the aluminum strip slitting machine is designed to shear from 0.5-5 mm, but when the slitting machine is used for shearing 4-5 mm, the disc cutters of the original equipment are always influenced and are difficult to shear, and the back marks and the notch burrs are easy to exist. For the use scene with smaller thickness, the shearing thickness and the width basically change little, so the number of the original matched cutters and distance sleeves 103 can meet the requirement, the configuration of the cutters and the distance sleeves 103 has larger range along with the change of the thickness of the product without implementing the shearing of the configuration of the male and female sleeves, if the configuration of the male and female sleeves is implemented, the configuration number can be greatly increased, and auxiliary facilities such as a grinding machine and the like are also configured by the cutters and the distance sleeves, otherwise, the cutter and the distance sleeves cannot be used, and the use is inconvenient. Therefore, the embodiment realizes the problem of larger thickness variation of the sheared materials by changing the shearing geometric angle.

In this embodiment, the bevel angles of the bevel edges of the upper blade 111 and the lower blade 112 are subjected to variable polishing according to the variation range of the thickness of the material, and according to practical experiments, the bevel angle is 3 ° when the material with the thickness of 4-5 mm is sheared, and the bevel angle is 4-5 ° when the material with the thickness of 5-7 mm is sheared, so that the better shearing effect of the thick material can be achieved.

As an alternative implementation of this embodiment, the tip width of the upper blade 111 and the lower blade 112 is 2mm. The width of the cutter point is generally required to be adjusted with the disc cutter structure of the original aluminum strip thick slitting machine.

As an alternative implementation manner of this embodiment, the parallelism of the two side surfaces of the upper blade 111 and the lower blade 112 is 0.003. In this embodiment, it is necessary to ensure the width tolerance requirement of the sheared material, reduce burrs at the edge after shearing the sheared material, and ensure shearing quality, and shear the strips on a wide width, where the width tolerance of each strip must be consistent, otherwise, the machining requirement cannot be met.

As an alternative implementation manner of this embodiment, the roughness of two side surfaces of the upper blade 111 and the lower blade 112 is 1.6. Similar to the case of parallelism, to ensure the width tolerance requirement of the sheared material, and to reduce burrs at the sheared edge of the sheared material and ensure shearing quality, the roughness of both sides of the upper blade 111 and the lower blade 112 is 1.6.

As an alternative implementation of the embodiment, the spacer 104 is made of steel. For the thick material shearing tool of the embodiment, when the upper cutter 111 and the lower cutter 112 are assembled, in order to reduce the processing cost and ensure the assembly quality, the spacer 104 can be made of steel, and the steel material can be subjected to heat treatment to maintain a certain hardness, so that the use effect is improved.

Example 2

With reference to fig. 1-2, this embodiment provides a thick material shearing tool, which can be modified on the basis of embodiment 1 as follows: the circular runout of the bevel edge of the upper blade 111 and the bevel edge of the lower blade 112 is 0.005. The strips are sheared on a wide breadth, and the width tolerance of each strip must be kept consistent, so that the cutter needs to control the size precision of the cutter, ensure the width tolerance requirement of sheared materials, reduce burrs at the edge of sheared materials and ensure shearing quality.

As an alternative to this embodiment, the distance sleeve 103 is a rubber sleeve. In this embodiment, the distance sleeve 103 is a rubber sleeve, which can support and protect the upper blade 111 and the lower blade 112.

As an alternative implementation of this embodiment, the transmission of the upper cutter shaft 101 and the lower cutter shaft 102 adopts biaxial driving.

The utility model and its embodiments have been described above by way of illustration and not limitation, and the utility model is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present utility model.
