Abstract
The utility model discloses a two-edged land scraper blade, which has the advantages of two sides edge, simple structure, easy to process, and long useful time. The utility model comprises a blade noumenon (1) and a firmware hole (2), it is characterized in that the two sides of the blade noumenon (1) are separately equipped with a blade(3).
Description
Technical field
The utility model relates to engineering machinery field, relates in particular to a kind of grader blade.
Background technology
At present, what grader blade commonly used both at home and abroad adopted all is asymmetric design, and blade easily produces distortion in heat treatment process.As shown in Figure 1, existing grader blade comprises blade body 1, firmware hole 2, one side be made as blade 3 in 1 liang of long limit of blade body, another side is made as heat treatment reversible deformation limit 4.In heat treatment process, the dependence experience is chosen the regional area Quenching Treatment on heat treatment reversible deformation limit 4, again to blade 3 omnidistance quenchings.Because blade structure is asymmetric, the zone of quenching is inconsistent, and interior tissue, the residual stress of every batch of material have difference, make the control of the 4 pairs of quenching distortions in heat treatment reversible deformation limit very limited, must just can enter next step operation through alignment process after quenching process.And heat treatment reversible deformation limit 4 can not be used as the blade of grader blade.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of bilateral blade that is provided with is provided, and is simple in structure, is easy to processing, the twolip grader blade of long service life.
Twolip grader blade of the present utility model comprises blade body and firmware hole, and two long limits of blade body are equipped with blade.
Described firmware hole is opened on the axis of symmetry of two blades or along the axis of symmetry symmetric arrangement of two blades.
Twolip grader blade of the present utility model is optimized the layout in firmware hole, transfers the heat treatment reversible deformation limit of former blade to blade, and the advantage of bringing thus is:
1, single dege blade is improved to double-edged blade, stock utilization is significantly improved, be doubled and redoubled application life, and use cost descends at double.
2, blade is a symmetric arrangement, and the heat treatment deformation amount of both sides blade equates that deformation direction is opposite, and final distortion is cancelled out each other, and has reduced the alignment manufacturing procedure, has improved production efficiency, has saved manpower.
When 3, double-edged blade only weares and teares on one side, do not need more to renew blade, only need the blade counter-rotating is installed, utilize the blade of another side, saved the calling of blade, set-up time, improved the efficiency of construction of land leveller.

The specific embodiment
Embodiment 1: as shown in Figure 3, Figure 4, twolip grader blade of the present utility model comprises blade body 1 and firmware hole 2, and two long limits of blade body 1 are equipped with blade 3.One group of firmware hole 2 is opened on the axis of symmetry of blade 3.
Embodiment 2: as Fig. 5, shown in Figure 6, twolip grader blade of the present utility model comprises blade body 1 and firmware hole 2, and two long limits of blade body 1 are equipped with blade 3.Two groups of firmware holes 2 are along the axis of symmetry symmetric arrangement of blade 3.
Twolip grader blade of the present utility model is symmetrical structure, in heat treatment process, can be respectively to two blades, 3 omnidistance quenchings, and the heat treatment deformation amount of two blades 3 equates that deformation direction is opposite, and distortion is cancelled out each other.
Only provided the set-up mode in one group and two groups firmware hole 2 among above-mentioned two embodiment, every a group or more firmware hole 2 all should be dropped within the protection domain of the present utility model along the mode of the axis of symmetry symmetric arrangement of sword 3.
Claims (3)
1, a kind of twolip grader blade comprises blade body (1) and firmware hole (2), it is characterized in that two long limits of described blade body (1) are equipped with blade (3).
2,, it is characterized in that described firmware hole (2) is opened on the axis of symmetry of two blades (3) according to the described twolip grader blade of claim 1.
3, according to claim 1 or 2 described twolip grader blades, it is characterized in that the axis of symmetry symmetric arrangement of described firmware hole (2) along two blades (3).
