Abstract
The utility model relates to picks, are applied to tunnelling machine, coalcutter, shield machine and Spiral digging machine field, are a kind of novel high wear-resistant picks, it is tooth handle below matrix including matrix, substrates are the tooth heads of bench-type structure, tooth head has the mounting groove of tooth tip, and there are also tooth tips to be mounted in mounting groove；It is characterized in that：One layer of protection ring is also bonded on matrix below the tooth tip; the protection ring is bonded by hard phase and Binder Phase; there is protection ring groove on matrix below the tooth tip; the protection ring is just bonded in inside protection ring groove; the protection ring is integrated whole structure; such novel high wear-resistant pick has higher abrasion resistance, energy first mate's degree improves the service life of pick due to taking protection ring.
Description
Technical field
The utility model relates to picks, are applied to tunnelling machine, coalcutter, shield machine and Spiral digging machine field.
Background technique
Pick is widely used in the fields such as coal mining, engineering rotary digging；In the prior art, pick composition mainly divides three parts group
At being tooth head, tooth handle and hard alloy tooth tip respectively, hard alloy tooth tip is fixed on the shrinkage pool of tooth head mainly with brazing mode
Interior, the rear part is in tooth head shrinkage pool without protective layer.In actual use, pick is by greater impact and abrasion, hard
Serious wear is divided on alloy tooth tip and tooth head.Pick dominant failure mode is that tooth head position wears no resistance, to hard when serious wear
Matter carbide button apical branch support protection not enough, causes hard alloy tooth tip to fall off failure, the pick ratio that such mode fails is up to
60%, have the shortcomings that durable effect is poor.
Summary of the invention
The purpose of this utility model improves a kind of pick that durability is strong aiming at disadvantages mentioned above --- a kind of novel height
Wear resistant cutting pick.
The technical solution of the utility model is such：A kind of novel high wear-resistant pick, including matrix are teeth below matrix
Handle, substrates are the tooth heads of bench-type structure, and tooth head has the mounting groove of tooth tip, and there are also tooth tips to be mounted in mounting groove；It is special
Sign is：One layer of protection ring is also bonded on matrix below the tooth tip, the protection ring is bonded by hard phase and Binder Phase
It forms.
Further speaking, there is protection ring groove, the protection ring is just bonded on the matrix below the tooth tip
It protects inside ring groove.
Further speaking, the protection ring is integrated whole structure.
Further speaking, the protection ring outer profile is arc.
Further speaking, the protection ring outer profile is the structure more bored.
Further speaking, also there are horizontally disposed cladding horizontal loops above the protection ring.
The utility model has the beneficial effects that：Such novel high wear-resistant pick is due to taking protection ring, the height having
Wearability can more effectively protect tooth head, and then extend falling off the time for hard alloy tooth tip in pick real work,
First mate's degree improves the service life of pick, is 3-4 times of traditional pick service life.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the utility model.
Wherein：1, matrix 2, tooth handle 3, tooth head 4, tooth tip 5, protection ring 6, cladding horizontal loops.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
It is tooth handle 2 below matrix, substrates are bench-types as shown in Figure 1, a kind of novel high wear-resistant pick, including matrix 1
The tooth head 3 of structure, tooth head have the mounting groove of tooth tip, and there are also tooth tips 4 to be mounted in mounting groove；It is characterized in that：The tooth tip
One layer of protection ring 5 is also bonded on following matrix, the protection ring is bonded by hard phase and Binder Phase.
Wherein hard phase is superhard material（Containing diamond particles, cubic boron nitride particle etc.）, ceramic particle（WC,TiC,
VC, SiC, NbC etc.）Equal hard particles, Binder Phase are the above alloys of binary such as iron, nickel, cobalt, copper, manganese, zinc, tin.
The utility model takes protection ring, and making pick at work has the function of protecting tooth tip, realizes that this is practical new
The long-lived effect of type.
Further speaking, there is protection ring groove, the protection ring is just bonded on the matrix below the tooth tip
It protects inside ring groove.Effect is the autoprotection for being conducive to protection ring, and using effect is more preferably.
Further speaking, the protection ring is integrated whole structure, is that cost is minimum in this way, bearing strength is high
Advantage.
Further speaking, the protection ring outer profile is arcuate structure, has the advantages that wearability is more preferable, such as Fig. 1 institute
Show, right side be protection ring outer profile is for arc.
Further speaking, the protection ring outer profile is the structure more bored, and has the advantages that tunneling effect is more preferable.Such as figure
Shown in 1, left side be protection ring outer profile is the structure more bored.
Further speaking, also there are horizontally disposed cladding horizontal loops 6 above the protection ring.The cladding is horizontal
Ring is the structure with protection ring one.
Above embodiments are only the section Example of the utility model, but the objective of the utility model is not limited to this, and are appointed
Within the field of the present invention, made changes or modifications all cover the patent model in the utility model to what those skilled in the art
In enclosing.
