Abstract
A kind of reinforced sand machine processed breaks carbide alloy breaker bars, and belong to a kind of parts of disintegrating machine, it comprises installation portion, blade and shoulder, and described blade top is provided with that pier contracts, that cross section becomes arcuation cutting edge, and described shoulder surface is arc rib.This reinforced sand machine carbide alloy breaker bars processed, by Upsetting arcuation cutting edge, makes carbide alloy breaker bars cutting edge form reinforcement, stressed more concentrated, more not easy fracture; Its arcuation cutting edge thickness increases by 0.2 times, and can slightly improve cutting edge toughness, increase broken contact surface, crushing effect is better; Be provided with the shoulder that 22-25 degree tilts, shoulder top is the impulsive force of arc rib effective slowly-releasing carbide alloy breaker bars, greatly strengthen the service life of carbide alloy breaker bars.
Description
Technical field
The utility model belongs to disintegrating machine part, is specially a kind of reinforced sand machine carbide alloy breaker bars processed.
Background technology
Be in the 3c mono-21cr height cast iron of theoretical research stage at present, in conjunction with all kinds of tup of disintegrating machine, by the Double-metal composite hammer that 3c mono-21Cr rich chromium cast iron and all kinds of carbon steel (containing 45# cast steel, 35# cast steel, 30# cast steel), potassium steel, low-alloy steel etc. form." biliquid " double-metal composite casting process adopted in research and the Technology for Heating Processing of composite casting ensure that metallurgical binding and the metallurgical quality of bimetallic binding site, guarantee that the binding site of bimetallic material is boundary simultaneously, each still keeps the characteristic of each metal material, makes the target that Double-metal composite hammer in use reaches safe, reliable, durable, economic.But this method still cannot effectively breaker bars be being subject to power when impacting in slowly-releasing sand process, and easily cause the breakage of carbide alloy breaker bars, service life is short.
Utility model content
The purpose of this utility model is: the sand machine carbide alloy breaker bars reinforced processed providing a kind of more not easy fracture.
In order to achieve the above object, the technical scheme adopted is:
A kind of reinforced sand machine carbide alloy breaker bars processed, it comprises installation portion, blade and shoulder, and described blade top is provided with that pier contracts, that cross section becomes arcuation cutting edge, and described shoulder surface is arc rib.
Shoulder is that 22-25 degree is tiltedly takeed on.
After the contracting of blade pier, the diameter of arcuation cutting edge increases 0.18-0.22 doubly.
The long 250mm of this breaker bars, high 26mm, thick 15mm.
The arc rib radius of shoulder surface is 0.9-1.1 times of its thickness.
The beneficial effect of employing technique scheme is: this reinforced sand machine carbide alloy breaker bars processed, by Upsetting arcuation cutting edge, makes breaker bars cutting edge form reinforcement, stressed more concentrated, more not easy fracture; Its arcuation cutting edge thickness increases by 0.2 times, and can slightly improve cutting edge toughness, increase broken contact surface, crushing effect is better; Be provided with the shoulder that 22-25 degree tilts, shoulder top is the impulsive force of the effective slowly-releasing breaker bars of arc rib, greatly strengthen the service life of carbide alloy breaker bars.
Accompanying drawing explanation
Fig. 1 is the structural representation of the reinforced sand machine carbide alloy breaker bars processed of the utility model;
Fig. 2 is the left side view of Fig. 1;
In figure, 1-installation portion, 2-blade, 3-shoulder.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is explained.
A kind of reinforced sand machine carbide alloy breaker bars processed, it comprises installation portion 1, blade 2 and shoulder 3, long 250mm, high 26mm, thick 15mm; Described blade 2 top is provided with that pier contracts, that cross section becomes arcuation cutting edge, and after the contracting of blade 2 pier, arcuation cutting edge diameter is 18mm; Described shoulder 3 is 25 degree and tiltedly takes on, and its surface is the arc rib of radius 15mm.
By bonding for the installation portion of carbide alloy breaker bars or be welded to tup and connect matrix, because carbide alloy breaker bars adopts high hard antifriction alloy, the impact force at contact of its blade exposed and broken thing is huge, and right angle shoulder easily ruptures; The size of its length, width and height can make an amendment according to different types, and at 250X26X15, this is of a size of conventional gauge size, and the oblique shoulder being provided with 22-25 degree can the impulsive force of effective slowly-releasing shoulder flanges, and reaching protection cutting edge, to be unlikely to again cutting edge effective length too low; Further shoulder 3 is set to the arc rib of certain radian, dispersibles shoulder rib portion stressed, protection shoulder is not fragile.The blade 2 of carbide alloy breaker bars is main broken contact point, its blade both sides are provided with tiltedly shoulder and disperse stressed, blade adopts Upsetting system to form the cutting edge of arcuation, one is add obdurability, two is form reinforcement effect at blade, and three increase blade lifting surface area, improve intensity and the service life of whole breaker bars greatly, not easy fracture, also improves crushing efficiency slightly.
