Problems solved by technology

However, due to the different hardness of the blanks, the overall chisel effect and service life of the impact tools are different. For example, the blanks are made of low-priced steel or medium-priced steel or high-priced steel. The more expensive the price, the higher the hardness of the steel material, the effect and service life are completely different

Embodiment 1

[0076] Refer to attached Figure 1-5 As shown, an impact tool includes a first element 1 and a second element 2 .

[0077] The hardness of the first original 1 is lower than that of the second original 2, for example, the first original 1 is cheap steel, and the second original 2 is medium steel, that is, the integration of two different hardnesses is realized, and the specific structure is as follows.

[0078] The first original 1 is provided with a handle 11 and a lower part 12, the handle 11 is connected to the lower part 12, the handle 11 can be an A-type handle, a B-type handle, a C-type handle, a D-type handle, an E-type handle or an F-type handle Or G-type handle or H-type handle or I-type handle or J-type handle or K-type handle or L-type handle. The shape of the handle 11 here can also be a Chinese invention patent, and the notification number is the dual-purpose handle 11 described in CN211278263U.

[0079] The lower part 12 includes a cylindrical portion 121 and a...

Embodiment 2

[0085] Refer to attached Image 6 As shown, the difference between Embodiment 2 and Embodiment 1 is that the second original 2 is arranged with a large top and a small bottom, that is, the second original 2 has a structure similar to a truncated cone, and the concave cavity 123 is also cylindrically arranged. During the embedding process, the second original 2 is more easily inserted into the cavity 123, and the top surface of the first original 1 and the top surface of the second original 2 form a common top surface and the two are closely attached, thereby forming The whole blank is then formed by forging.

Embodiment 3

[0087] Refer to attached Figure 7 As shown, the difference between Embodiment 3 and Embodiment 1 is that the second element 2 here is arranged with a small top and a large bottom, that is, the second element 2 as a whole has a structure similar to a truncated cone, and the concave cavity 123 is also cylindrical. Set, during the embedding process, the bottom surface of the second original 2 is closely attached to the bottom surface of the concave cavity 123, and there is a gap between the top surface of the second original 2 and the top surface of the first original 1, but this gap is due to the process of forging After punching, the first original 1 is squeezed, so that the two are firmly fixed to form a pointed part. The fixing strength formed by this structure is stronger, the opening of the concave cavity 123 is narrowed, and the second original 2 is less likely to fall off.

Abstract

The invention discloses an impact tool and a machining process thereof. The impact tool comprises a first original part and a second original part, and the first original part and the second original part form the tip of the impact tool; and the hardness of the first original part is lower than that of the second original part. The impact tool is convenient in machining, low in cost and high in hardness, and has an autogenous grinding effect.

Description

technical field [0001] The invention relates to an impact tool and its processing technology. Background technique [0002] Existing impact tools are generally blanks of the same material, which are processed to form impact tools. However, due to the different hardness of the blanks, the overall chisel effect and service life of the impact tools are different. For example, the blanks are made of low-priced steel or medium-priced steel or high-priced steel. The more expensive the price, the higher the hardness of the steel material, and the effect and service life are completely different. Therefore, how to control the quality of the impact tool while reducing the production cost has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an impact tool and its processing technology. [0004] The technical solution adopted by the present invention to s...
