Abstract
This utility model relates to excavator accessory field, is specifically related to a kind of gravel type wear-resistant bucket tooth, and it includes that tooth head, the flank of tooth, tooth root and the ribs being located on the flank of tooth, described tooth head are the yi word pattern of level, and the thickness of the described flank of tooth is 12 18mm；All being welded with scuff-resistant coating on described tooth head, the flank of tooth and ribs, described scuff-resistant coating is welded jointly by the hard alloy particle of the metal powder core solder wire of HRC60 with HRC90；The scuff-resistant coating of the described flank of tooth by parallel one flank of tooth scuff-resistant coating I arranged up and down with together with flank of tooth scuff-resistant coating II form.
Description
Technical field
This utility model relates to excavator accessory field, is specifically related to a kind of gravel type wear-resistant bucket tooth.
Background technology
Under normal operating condition, normal pressure and frictional force are the primary outer lost efficacy to the bucket tooth of current most of excavator
Mechanics factor.Frequently changing bucket tooth makes production efficiency low, and labor strength is big.
In order to strengthen its service life, extend the replacement cycle, it is necessary to improve the wearability of bucket tooth.One way in which is
Be welded on bucket tooth hard alloy steel plate, which increases bucket tooth deadweight, improves production cost.Also having a kind of mode is at bucket tooth
Directly cast out groove, the most in a groove sealing weld hard alloy material；When actually used, this mode has the biggest defect, a side
Face, the limit normal pressure that groove makes bucket tooth bear is greatly reduced, and bucket tooth material is harder crisp in addition, is more easy to wear out failure the most disconnected
Split；On the other hand, filler weldering in the narrowest but also short groove, the technology of operator is required higher.Just because of this, above-mentioned this two
Kind of mode is not suitable for that the flank of tooth is less, the gravel type bucket tooth of thinner thickness.
Summary of the invention
In order to solve the problems referred to above, this utility model provides a kind of gravel type wear-resistant bucket tooth, and it has good wear-resisting energy
Power and shovel dig ability, and technique is simple, low cost.
The technical solution adopted in the utility model is as follows:
A kind of gravel type wear-resistant bucket tooth, including tooth head, the flank of tooth, tooth root and the ribs being located on the flank of tooth, described tooth head is
The yi word pattern of level, the thickness of the described flank of tooth is 12-18mm；
All be welded with scuff-resistant coating on described tooth head, the flank of tooth and ribs, described scuff-resistant coating by the metal powder core solder wire of HRC60 with
The hard alloy particle of HRC90 is welded jointly；
The scuff-resistant coating of the described flank of tooth by parallel one flank of tooth scuff-resistant coating I arranged up and down with together with flank of tooth scuff-resistant coating II group
Become.
Above-mentioned gravel type wear-resistant bucket tooth, the width of described flank of tooth scuff-resistant coating I and flank of tooth scuff-resistant coating II is 10-15mm, institute
State and be spaced apart 18-22mm between flank of tooth scuff-resistant coating I and flank of tooth scuff-resistant coating II.
The beneficial effects of the utility model are:
1, this utility model uses carbide mosaic welding procedure, the gold of the hard alloy particle of HRC90 Yu HRC60
Belong to flux cored wire and be jointly welded on bucket tooth surface, simple process.
2, scuff-resistant coating thickness is reasonably distributed at about 5-8mm, flank of tooth scuff-resistant coating, will not weaken the mining ability of bucket tooth, can
To improve its service life of 3-8 times and to be greatly saved manufacturing cost, improve digging efficiency.
Accompanying drawing explanation
Fig. 1 is front elevational schematic of the present utility model；
Fig. 2 is schematic side view of the present utility model；
In figure: 1 be tooth head, 2 be the flank of tooth, 3 be ribs, 4 be tooth root, 21 be flank of tooth scuff-resistant coating for flank of tooth scuff-resistant coating I, 22
Ⅱ。
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further explained.
As depicted in figs. 1 and 2, the gravel type wear-resistant bucket tooth of the present embodiment, including tooth head 1, the flank of tooth 2, tooth root 4 be located at tooth
Ribs 3 on face 2, described tooth head 1 is the yi word pattern of level, and the thickness of the described flank of tooth 2 is 12-18mm；Described tooth head 1, tooth
All being welded with scuff-resistant coating on face 2 and ribs 3, described scuff-resistant coating is by the hard alloy of the metal powder core solder wire of HRC60 Yu HRC90
Grain is welded jointly；
The scuff-resistant coating of the described flank of tooth 2 by parallel one flank of tooth scuff-resistant coating I 21 arranged up and down with together with flank of tooth scuff-resistant coating
II 22 compositions.It is so designed that, on the premise of reaching excellent abrasive resistance, simplified processing process, save material, reduce and produce into
This.
Above-mentioned gravel type wear-resistant bucket tooth, the width of described flank of tooth scuff-resistant coating I 21 and flank of tooth scuff-resistant coating II 22 is 10-
15mm, is spaced apart 18-22mm between described flank of tooth scuff-resistant coating I 21 and flank of tooth scuff-resistant coating II 22.
