Abstract
The utility model discloses a kind of bimetal wear blocks.The wear-resistant block includes top high chromium cast iron layer and lower part low carbon steel layer, and cone machine hole is machined on low carbon steel layer, and aperture is less than lower aperture thereon, and the downward convex block of high chromium cast iron layer and the cone machine hole match, and double layer of metal fits closely connection and do not fall off.The wear-resistant block when in use, will not be there is a phenomenon where removing even if high chromium cast iron layer is all worn with low carbon steel layer, and service life increases.Low carbon steel layer cone machine hole machining period is few, with low content of technology, reduces production cost.
Description
Technical field
A kind of the utility model application wear-resistant material industry, and in particular to bimetal wear block for wearing layer repair welding.
Background technique
Wear-resistant block is the various wear-resistant positions of machinery, main choosing when especially cambered surface or irregular surface need wear-resistant
It selects, such as inner surface, inner surface of converyor roller of abrasion-proof pipe etc..Different wear-resistant blocks and equipment matrix connection type are not
Together, due to being limited by material property, ceramic wear-resisting block mostly uses the form of bonding, and steel material wear-resistant block mostly uses bolt
The mode of connection, bimetal wear block mostly use the form of welding.
Bimetal wear block is mostly combined by the good mild steel of welding performance and the good rich chromium cast iron of wearability, and one
As using vacuum copper brazing technique make, i.e., under vacuum conditions, utilize copper as solder flux, under the effect of the pressure, will be low
Carbon steel and rich chromium cast iron are brazed together.The wear-resistant block is generally used for room temperature or slightly higher temperature case, it is impossible to be used in high temperature.Special
Benefit is application No. is in 201510486129.2 " wear-resistant block and preparation method thereof for protecting bucket ", using than being brazed into
This low casting method produces A3 straight carbon steel and the compound wear-resistant block of wear resistant cast iron.In the structure of the wear-resistant block, the general carbon of A3
Trapezoidal or spherical protrusions in steel layer are process, and the processing cost of convex block is high.The wear-resistant block of the structure in use, when
High chromium cast iron layer is worn to a certain extent, and when convex block can not fix high chromium cast iron layer, high chromium cast iron layer can be de- from A3 common carbon steel layer
It falls, wear-resistant block is caused to fail, service life is lower.
Summary of the invention
The technical issues of the utility model is solved is: providing a kind of bimetal wear block, can reduce production cost, improves
Service life.
The technical scheme adopted by the utility model is the bimetal wear block includes that top high chromium cast iron layer and lower part are low
Carbon steel layer is machined with cone machine hole on the low carbon steel layer, and aperture is less than lower aperture, the downward convex block of the high chromium cast iron layer thereon
Match with the cone machine hole, double layer of metal fits closely connection and do not fall off, and wear-resistant block is avoided in the position that boss is connected with cone machine hole
Edge.
The beneficial effects of the utility model are: the bimetal wear block is when in use, even if high chromium cast iron layer is all worn,
It will not be there is a phenomenon where being removed with low carbon steel layer, service life increases.The cone machine hole machining period of low carbon steel layer is few, technology
Content is low, reduces production cost.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Wherein: 1- high chromium cast iron layer, 2- low carbon steel layer, 3-V v notch v.
Specific embodiment
Attached FIG. 1 is a schematic structural view of the utility model, including the good high chromium cast iron layer 1 of top wear-resisting property and lower part weldering
Low carbon steel layer 2 of good performance is connect, is machined with cone machine hole on low carbon steel layer 2, the upper aperture of the cone machine hole is less than lower aperture.Gao Ge
1 upper surface of cast iron layer is working face, and there is convex block in lower surface, and the cone machine hole on the downward convex block and low carbon steel layer 2 matches, two layers
Metal in close, which is fitted and connected, not to be fallen off.Avoid the edge welding position of wear-resistant block in the position that boss is connected with cone machine hole.
The wear-resistant block when in use, can be broken from V-notch 3 it is disconnected, to adapt to the shape and size of wearing layer soldering, then
It is welded to connect with equipment matrix.
When the wear-resistant block produces, hot rolled steel plate is can be used in low carbon steel layer, drills out cone machine hole on the steel plate using target drill.
The steel plate for being drilled hole is put into casting mold cavity, high temperature rich chromium cast iron molten metal of casting, molten metal fills cone machine hole and formed and bored
The matched boss in platform hole forms close connection after cooling and shaping.
The wear-resistant block in use, even if high chromium cast iron layer all wear, will not there is a phenomenon where with low carbon steel layer remove,
It increases the wear-resisting of wear-resistant block and uses time and service life.In addition, processing cone machine hole is than processing trapezoidal or spherical boss on the steel plate
With low content of technology, machining period is also few, reduces processing cost and cost of labor.
