Abstract
The utility model relates to a trigonal drill for mechanical working. The working part of the utility model is made into a triangular prism shape by compressing the ternary alloy, thereby that the utility model is simple, multi-blade, wear-resisting, highly effective, low in manufacturing cost and capable of being used for mechanical working, repairing, processing before and after heat hardening alloy moulds and further playing an important role in many mould manufacturing processes.
Description
The utility model relates to a kind of Three-square drill that is used for the machining aspect.
Our drill bit of use is generally fluted drill at present, and fluted drill is difficult for creeping into when running into hard material, is easy to be fractureed.
The purpose of this utility model just provides a kind ofly creeps into when running into hard material easily, and the Three-square drill of frangibility not.
The technical solution of the utility model realizes that by following approach its working portion is suppressed form triangular prism shaped by tripartite alloy.
The utlity model has simple multiple-cutting-edge, wear-resisting, the effect height, cost is low.Can be applicable to the processing of machining, repairing, alloy die steel quenching front and back, and in a lot of die manufacture, playing a crucial role.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a working portion structural representation of the present utility model.
Describe the technical solution of the utility model and embodiment in detail below in conjunction with accompanying drawing.
The utility model contains working portion 1, shank 2, and described working portion 1 is to suppress form triangular prism shaped by tripartite alloy, and shank 2 is cylindrical, adopts the high-quality steel to make, and adopts combined welding to form between working portion 1 and the shank 2.
Claims (1)
1, a kind of Three-square drill contains working portion (1), shank (2), it is characterized in that described working portion (1) is to suppress form triangular prism shaped by tripartite alloy.
