Problems solved by technology

For the overall forged hammer head, although the titanium alloy material with heat treatment strengthening effect can be used to increase the hardness, it cannot achieve hardness differentiation. Even if there are natural differences in the hardness of different parts, the difference is very small and cannot meet the requirements.

Embodiment Construction

[0023] Attached below figure 1 , 2 , 3, 4 describe an embodiment of the present invention.

[0024] The combined titanium alloy hammer has a hammer head 1 and a handle 2. The hammer head 1 is set on one end of the handle 2 through a connecting hole 8. The hammer head 1 is a split structure and consists of a body 3, a striking body 4 and a horn 5. The body 3 , The knocking body 4 and the croissant 5 adopt reliable and convenient connection methods according to different requirements: such as welding, bolt fastener connection, shrinkage connection, fixed pin connection and other methods. The knocking body 4 and horns 5 are made of forgings, the body 3 is a casting or forging and the hardness of the body 3 is lower than that of the knocking body 4 and horns 5, and the knocking body 4 and horns 5 are made of Ti-10V-3Al-2Fe , 15V-3Al-3Cr-3Sn, 4AL-22V, SP700, 13V11Cr, TC18, 2041 and other β or near β series titanium alloys, the measured tensile strength is usually between 895MPa-1...

Abstract

The invention provides a combined titanium alloy hammer, which comprises a hammer head and a handle, wherein the hammer head is sleeved at one end of the handle through a connecting hole; and the hammer head has a split structure and consists of a body, a knocking body and a cleat which are fixedly connected into a whole. The combined titanium alloy hammer is favorable for well solving the technical problem of differential distribution of hardness on the same hammer head, so that the complex shape design can be fully realized in production; and meanwhile, the refining degree of product appearance is improved, the manufacturing cost of the product is reduced, and the hammer has a very high practical value.

Description

technical field [0001] The invention belongs to the technical field of hardware tool products, and in particular relates to a combined titanium alloy hammer. Background technique [0002] Titanium alloy has the excellent characteristics of small specific gravity, high specific strength and corrosion resistance, which can reduce the weight, reduce the labor intensity of the user, and improve the service life of the product, so the titanium alloy hammer has a good market application prospect. The hammer head of the titanium alloy hammer head developed and sold in small batches in the market is generally produced by integral precision casting or integral forging of titanium alloy, but it cannot be widely used due to the following problems: the metal structure of the overall cast hammer head product is a casting structure, Metal compactness is poor, strength is low, tensile strength is mostly lower than 900MPA, and hardness is less than HRC33, which is far from the surface hardn...
