Description
Technical field
The present invention relates to excavator accessories field, and in particular to a kind of preparation method of excavator bucket teeth.
Background technology
Bucket tooth is the easy consumption part in the excavator course of work, especially crown position, during with contacting material high speed contact, by
The impulsive force arrived is than stronger, if intensity, than relatively low, tooth tip portion easily deforms upon, increase and and material with excavating depth
Relative motion, forward extrusion power can be produced to the whole surface of bucket tooth, especially in excavating rock class material, bucket tooth and material it
Between frictional force it is bigger, therefore the intensity of bucket tooth and construction determine the service life of bucket tooth；On the other hand, crown is sharp
Degree determines operating efficiency, and the too thick blunt excavating resistance of crown is big, and too thin intensity is not high, easily loses.Existing bucket tooth has wedge
Shape, flat, sticker type etc., wedge shape, the bucket tooth of flat are more with more blunt, and the ratio of sticker type is sharp but the small wear-resistant rate of intensity
It is low.
The content of the invention
In order to solve the above technical problems, technical scheme proposed by the present invention is：A kind of preparation method of excavator bucket teeth, bag
Connecting seat, crown are included, left and right sidewall of the connecting seat away from described crown one end is provided with counterbore, the crown upper and lower end face
Concave surface is provided with, the concave surface extends to the forward position of the crown from the junction of the connecting seat and the crown, described
Concave surface is provided with a plurality of first reinforcement, the pointed tooth separated at equal intervals is provided with the free end of the crown, through the point
Tooth is provided with the second reinforcement.
Wherein, the pointed tooth arranges along the linear type of the crown width.
Further, the pointed tooth is located at the centre of the crown free end, is set in the both sides of the crown free end
Stopper section is set to, second reinforcement is through the pointed tooth and is fixed on the inside of the stopper section.
Wherein, the concave surface includes cancave cambered surface and horizontal plane, and the cancave cambered surface is located at close to one end of the connecting seat, court
The horizontal plane is bent downwardly, and the horizontal plane is located remotely from one end of the connecting seat, is connected with the cancave cambered surface.
Wherein, the shape of the first reinforcement bottom surface is engaged with the concave surface, the top surface of first reinforcement from
The linear type in forward position of the crown extends upwardly to the concave surface rearward end.
Wherein, the pointed tooth is extended to the leading section of the concave surface by the free end edge of the crown.
Further, second reinforcement is passed through in the centre position of the pointed tooth.
The present invention has the advantages and positive effects of：The crown free end of the present invention is arranged to the pointed tooth of separation, carries
The high sharpness of crown, more conducively excavates, pointed tooth is provided with the second reinforcement, the impulsive force that pointed tooth is subject to is disperseed
Come, ensure that pointed tooth is not pliable under a larger impact force or deforms, the service life of bucket tooth has been effectively ensured；Crown
Top sets concave surface, reduces the thickness of crown, improves the sharpness of crown, and a plurality of first is provided with concave surface and is strengthened
Muscle, improve crown overall fastness and impact resistance.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure：1. connecting seat, 2. crowns, 3. counterbores,
41. cancave cambered surface, 42. horizontal planes, 5. stopper sections,
51. pointed tooth, 6. second reinforcements, 7. first reinforcements
Embodiment
The embodiment of the present invention is elaborated below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of preparation method of excavator bucket teeth, including connecting seat 1, crown 2, the connecting seat 1 are remote
The left and right sidewall of described one end of crown 2 is provided with counterbore 3, and the upper and lower end face of crown 2 is provided with concave surface, and the concave surface is from described
The junction of connecting seat 1 and the crown 2 extends to the forward position of the crown 2, and being provided with a plurality of first on the concave surface strengthens
Muscle 7, the pointed tooth 51 separated at equal intervals is provided with the free end of the crown 2, the second reinforcement is provided with through the pointed tooth 51
6。
Wherein, the pointed tooth 51 arranges along the linear type of the width of crown 2.
Further, the pointed tooth 51 is located at the centre of the free end of crown 2, the two of the free end of crown 2
Side is arranged to stopper section 5, and second reinforcement 6 is through the pointed tooth 51 and is fixed on the inner side of stopper section 5, the backstop
The width in portion 5 is more than the width of the pointed tooth 51, and the one side of stopper section 5 can protect pointed tooth 51 to be impacted by its both sides, another
Aspect fixes the fastness that the second reinforcement 6 ensures the forward position of crown 2.
Wherein, the concave surface includes cancave cambered surface 41 and horizontal plane 42, and the cancave cambered surface 41 is located at close to the connecting seat 1
One end, it is bent downwardly towards the horizontal plane 42, the horizontal plane 42 is located remotely from one end of the connecting seat 1, with the concave arc
