Description

Technical Field

[0001] The utility model belongs to the technical field of cold scissor blades, in particular to a novel cold scissor blade. Background Art

[0002] When rolling round steel, cold shears are often used. After the round steel is cut into the set length, it is collected and bundled. Cold shears are key equipment in the bar production line. Their shearing force is 850 tons or more. The upper shear blade is V-shaped and the lower shear blade is flat, which is designed to share the shearing force. The price of the upper and lower blades is 10,000 yuan per piece, and the consumption is also huge.

[0003] The existing cold shear blade has two flat shearing blades and two V-shaped shearing blades on the upper blade. The two V-shaped shearing blades can be used by turning over. The lower blade has four flat shearing blades, which can be used by turning over and reversing the blades. The upper and lower blade seats and the upper and lower blade mating surfaces are all flat, which means that only two V-shaped shearing blades can be used on the upper blade. The two V-shaped shearing blades of the original upper blade are directly scrapped after use, and the two flat blades cannot be used. Usually, the stock ratio of upper and lower blades is 2:1.

[0004] Therefore, the present application provides a novel cold shears blade. Utility Model Content

[0005] The utility model aims to provide a novel cold shearing scissors blade, which can make use of two flat shearing blades of an upper knife.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A novel cold shear blade comprises an upper blade, wherein the blade of the upper blade comprises two flat blades and two V-shaped blades, a threaded hole is arranged on the blade body of the upper blade on one side of the V-shaped blade, and an inclined pad is connected to the threaded hole through a connecting bolt.

[0008] Furthermore, one side of the inclined pad is configured as a plane structure, and the other side is configured as an arc structure in close contact with the V-shaped shear blade.

[0009] Furthermore, a process opening is provided on the inclined pad block.

[0010] Furthermore, it also includes a lower knife used in conjunction with the upper knife, and the blade of the lower knife includes four flat shearing blades.

[0011] Compared with the prior art, the utility model has at least one of the following beneficial effects:

[0012] During use, first install the flat shear blade of the upper knife and one side of the flat shear blade of the lower knife on the knife seat, and then use the two V-shaped shear blades of the upper knife and the two flat shear blades of the lower knife to cooperate for shearing; when the V-shaped shear blade of the upper knife cannot be used, a threaded hole is set on the knife body on one side of the V-shaped shear blade of the upper knife, and an inclined pad is connected to the threaded hole through a connecting bolt. At this time, one side of the original V-shaped shear blade also becomes a plane, and this side is installed on the knife seat, and the flat shear blade of the original upper knife that has not been used is used as the lower knife, so there is no need to purchase the lower knife. It can save a lot of procurement funds and production costs for enterprises, and there is no need for a transformation cycle, which has significant social and economic benefits.

[0019] like Figure 1-5 In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Example

[0020] A new type of cold shear blade includes an upper blade 1, and the blade of the upper blade 1 includes two flat shear blades and two V-shaped shear blades. The upper blade 1 is provided with a threaded hole 2 on the blade body on one side of the V-shaped shear blade, and an inclined pad 4 is connected to the threaded hole 2 through a connecting bolt 3. During use, the flat shear blade of the upper blade and one side of the flat shear blade of the lower blade are first installed on a blade holder, and then the two V-shaped shear blades of the upper blade and the two flat shear blades of the lower blade are used together for shearing; when the V-shaped shear blade of the upper blade cannot be used, a threaded hole is provided on the blade body on one side of the V-shaped shear blade of the upper blade, and an inclined pad is connected to the threaded hole through a connecting bolt. At this time, one side of the original V-shaped shear blade also becomes a plane, and this side is installed on the blade holder, and the flat shear blade that was not used by the original upper blade is used as the lower blade, so that there is no need to purchase the lower blade. It can save a lot of procurement funds and production costs for enterprises, and there is no need for a transformation cycle, which has significant social and economic benefits.

[0021] More specifically, one side of the inclined pad 4 is configured as a plane structure, and the other side is configured as an arc structure that is in close contact with the V-shaped shear blade, so as to better be in close contact with the upper knife.

[0022] More specifically, a process opening is provided on the inclined pad 4 to solve the processing error of the middle vertex of the V-shaped shear blade.

[0023] More specifically, it also includes a lower knife 5 used in conjunction with the upper knife 1. The blade of the lower knife 5 includes four flat shearing edges, which cooperates with the upper knife 1 to perform shearing.

[0024] Although the utility model is described herein with reference to a plurality of illustrative embodiments of the utility model, it should be understood that those skilled in the art may devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein.
