Abstract
This patent relates to one and mixes and stirs cutter, comprise tool matrix axle, it is characterized in that: described tool matrix axle has a flange portion, flange portion side is provided with the tool matrix of truncated cone-shaped, the end of tool matrix is provided with conical point of a knife, tool matrix is provided with antifriction alloy overlay cladding, and flange portion opposite side is set with elasticity distensible ring, elasticity distensible ring have together with the gap of the axis being parallel of tool matrix axle.Advantage is: the existing higher obdurability of this patent, has again higher abrasion resistance, long service life.
Description
Technical field
The invention belongs to road building machinery technical field, particularly relates to one and mixes and stirs cutter.
Background technology
At present, in the construction of road building machinery, owing to will mix and stir the dirt etc. of the gravel of various sizes and ratio, sand, cinder and heterogeneity, mixing and stirring the degree of depth also has very big-difference, the applying working condition mixing and stirring cutter is very complicated and severe, is that one uses consumable accessory widely.
What existing engineering machinery mixed and stirred cutter with equipment structure is: Integral alloy steel knife body front end seting welding carbide.Cutter hub adopts the medium carbon low alloy steel material of forging (or casting) after machine is shaped, and by Quench and temper heat treatment, has certain obdurability and abrasion resistance simultaneously.But, because the abrasion resistance of alloy steel is well below carbide alloy, often because alloy steel cutter hub front portion produces wearing and tearing too early in the use of cutter, can not continue to support hard alloy cutter bit, just producing to come off too early when the wear extent of point of a knife is very little makes cutter scrap, and causes great waste.This cutting-tool's used life is short, adds engineering cost.
Summary of the invention
The invention provides one to mix and stir cutter for solving in known technology the technical problem that exists, and this mixes and stirs the existing higher obdurability of cutter kind, has again higher abrasion resistance, long service life.
One mixes and stirs cutter, comprise tool matrix axle, tool matrix axle has a flange portion, flange portion side is provided with the tool matrix of truncated cone-shaped, the end of tool matrix is provided with conical point of a knife, tool matrix is provided with antifriction alloy overlay cladding, and flange portion opposite side is set with elasticity distensible ring, elasticity distensible ring have together with the gap of the axis being parallel of tool matrix axle.
The invention can also by the following technical solutions:
Preferred technical scheme, additional technical feature is: tool matrix adopts medium carbon low alloy steel, and antifriction alloy overlay cladding adopts the preparation of plasma arc alloy powder technique for overlaying.
Preferred technical scheme, additional technical feature is: antifriction alloy overlay cladding thickness is 1.0 ~ 6.0mm, and hardness is 40 ~ 65HRC.
The advantage that the invention has and good effect are:
Because the invention adopts technique scheme, by improving the structure of cutter, the original cutter by medium carbon low alloy steel is changed into the method for build-up wear-resistant alloy-layer on tool matrix, cutter is made to keep the high-strength tenacity of original axle body material simultaneously, improve the anti-wear performance of cutter, extend cutting-tool's used life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the invention;
In figure: 1, point of a knife; 2, antifriction alloy overlay cladding; 3, tool matrix; 4, flange portion; 5, elasticity distensible ring.
Detailed description of the invention
For innovation and creation content, the Characteristic of the invention can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in Figure 1,
One mixes and stirs cutter, comprise tool matrix axle, tool matrix axle has a flange portion 4, flange portion side is provided with the tool matrix 3 of truncated cone-shaped, the end of tool matrix is provided with conical hard alloy cutter bit 1, tool matrix is provided with antifriction alloy overlay cladding 2, and flange portion opposite side is set with elasticity distensible ring 5, elasticity distensible ring have together with the gap of the axis being parallel of tool matrix axle.Tool matrix adopts medium carbon low alloy steel, and antifriction alloy overlay cladding adopts the preparation of plasma arc alloy powder technique for overlaying, and thickness is 1.0 ~ 6.0mm, hardness is 40 ~ 65HRC.
The operating principle of the invention is:
Because the core of axle is still medium carbon low alloy steel, so can ensure that tool matrix axle has enough intensity and toughness.Meanwhile, the antifriction alloy overlay cladding be positioned at outside tool matrix has higher hardness, can significantly improve the anti-wear performance mixing and stirring cutter.
When needs will mix and stir on Cutting tool installation manner to tool rest, need elasticity distensible ring to compress, its external diameter is diminished.Then put in the hole of tool rest by elasticity distensible ring together with tool matrix axle, elasticity distensible ring can by tool rest swelling when expanding.Operationally, elasticity distensible ring is relative with between tool rest fixing for cutter, the rotary motion in elasticity distensible ring of tool matrix axle.
Although be described the preferred embodiment of the invention by reference to the accompanying drawings above; but the invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of the invention; do not departing under the ambit that the invention aim and claim protect, can also make a lot of form, these all belong within the protection domain of the invention.
