The utility model discloses a kind of main cutting plate, the plate body that blade surface is mainly provided with by one piece of side is formed, and the angle of blade surface is 26 °, and the cutting edge thickness of blade surface is the 1/6 of plate body thickness.The main cutting plate has the advantages that：(1) blade surface is located at plate body length direction, and angle is 26 °, and cutting edge thickness is the 1/6 of plate body thickness, it is possible thereby to improve operating efficiency, is increased the service life；(2) plate body case hardness is 40HRC 80HRC, and blade surface partial depth is that the hardness at 10mm is not less than 35HRC, and the core minimum hardness of plate body other parts is 35HRC, and thus main cutting plate is more sturdy and durable；(3) orientation of mounting hole and the setting direction of blade surface are parallel, and thus mounting hole is not only more firmly mounted close to blade surface side, and easy for removal and installation；(4) above-mentioned technology is based on, the utility model additionally provides a kind of main cutting plate, and plate body thickness is 30mm, and the cutting edge thickness of blade surface is 5mm, and it can be applied to most of bull-dozers as standard component.
Description
Technical field
Engineering machinery accessory is the utility model is related to, more particularly to a kind of main cutting plate.
Background technology
Bull-dozer is a kind of engineering truck, and front is equipped with large-scale metal dozer blade (i.e. main cutting plate), during use
Main cutting plate to be put down, backing-off cutting and pushes mud, sand and stone etc. forward, soil-shifting function is individually completed to cut the earth, muck haulage and unloads geotechnological work,
Have the characteristics that operation is flexible, rotation is convenient, required working face is small, travel speed is fast.It is primarily adapted for use in one to three class soil
The short fortune of shallow cut, such as site clearing or smooth, the little foundation ditch of cutting depth and backfill, push away and build highly little roadbed etc..When
When the operating mode of bull-dozer is chaotic mine of the mixed and disorderly wild country of weeds, native stone etc., dozer blade easily with stone severe impact.
At present, main cutting plate used on bull-dozer, blade surface typically set angle to be less than 20 °, cause front end easy to wear,
Impact resistance is poor, easy tipping, so as to have impact on the service life of main cutting plate, and then reduces the operating efficiency of bull-dozer.
Utility model content
The purpose of this utility model is to provide a kind of main cutting plate.
According to one side of the present utility model, there is provided a kind of main cutting plate, be mainly provided with blade surface by one piece of side
Plate body is formed, and the angle of blade surface is 26 °, and the cutting edge thickness of blade surface is the 1/6 of plate body thickness.
In some embodiments, plate body thickness is 30mm, and the cutting edge thickness of blade surface is 5mm.
In some embodiments, plate body case hardness is 40HRC-80HRC.
In some embodiments, blade surface partial depth is that the hardness at 10mm is not less than 35HRC, plate body other parts
Core minimum hardness is 35HRC.
In some embodiments, also at least provided with two row's mounting holes, length direction of the mounting hole along plate body on plate body
It is arranged in a straight line.
In some embodiments, blade surface is set along plate body length direction.
In some embodiments, the orientation of mounting hole and the setting direction of blade surface are parallel, and mounting hole is close to sword
Face side.
Using the main cutting plate of above technical scheme by the redesign to structure, compared with existing product, have
Following beneficial effect：
(1) blade surface is located at plate body length direction, and angle is 26 °, and cutting edge thickness is the 1/6 of plate body thickness, it is possible thereby to
Operating efficiency is improved, is increased the service life；
(2) plate body case hardness is 40HRC-80HRC, and blade surface partial depth is that the hardness at 10mm is not less than 35HRC, plate
The core minimum hardness of body other parts is 35HRC, and thus main cutting plate is more sturdy and durable；
(3) orientation of mounting hole and the setting direction of blade surface are parallel, and mounting hole is close to blade surface side, thus not only
It is more firmly mounted, and it is easy for removal and installation；
(4) above-mentioned technology is based on, the utility model additionally provides a kind of main cutting plate, and plate body thickness is 30mm, blade surface
Cutting edge thickness is 5mm, and it can be applied to most of bull-dozers as standard component.
Brief description of the drawings
Fig. 1 is a kind of main cutting plate structure schematic diagram of embodiment of the utility model.
Fig. 2 is sectional view of the main cutting plate along A-A directions shown in Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
