Fixing method for bucket tooth and adapter assembly

1/4/2019 1:56:11 PM

1, the installation of new electric power. At the same time, accurate mapping aggressive tooth cavity and the adapter assembly binding geometry of parts, and bend into the model, after repeated testing and physical modification, finally draw the pattern.
2, use the bucket tooth model to test the bucket tooth new parts assembly part is qualified or not, using adapter model to test adapter in the amount of wear in the late process used in the bucket. If the adapter has some wear and tear, the maintenance interval equipment or replacement of bucket teeth timely to wear parts for welding, and grinding to model fit, and then install a new bucket tooth.
So, in the whole process of electric excavator, can maintain long-term careful examination and to repair, maintain close coordination of bucket teeth with adapter, it will make the electric excavator shovel with safety and efficient operation.

Bucket teeth shell layers

1/2/2019 12:35:18 PM

The shape and structure of the cast of different layers of shell, there will be differences. For example, with elongatedslot casting Kong Huo need to do two or three times the surface layer; the general casting two times to do the backing layer is enough, and the relatively large castingsmay require three or more layers. Cost of shell castings per kilogram is about 5.9 yuan, of which the material costs accounted for 67.8%, fuel and poweraccounted for 23.9%,accounted for 13.3% of wages. In the 4 yuan / kg of shellmaterial, zircon sand andzirconium powder consumptionaccounted for 63%, accounted for the entire cost of shell42.7%, silica sol costs accounted for about 12.2% of the cost of making shell. Although the zircon zirconium powderwas used for the surface layer.

Bucket teeth sticking sand prevention measures

1/4/2019 1:57:59 PM

We in the bucket teeth, sometimes sticky sand phenomenon, so how to prevent bucket tooth bonded sand?
1, compared with cast iron, cast steel casting temperature is higher, sometimes as high as 1560 - 1620 ℃, high casting temperature is mainly to prevent steel casting cold lap, but at the same time, such a high temperature thermal effect on the sand for long time, the cast big scouring force. Core sand in the back of the sand can not, because the return sand, fine sand, dust, iron sand too much, this will lead to sand sintering temperature is low, so the time to add new sand.
Compaction is not the problem .
2, sand mold casting sand sand stick, certainly not tight, in before casting must each piece of sand are tested, to enhance and ensure the casting compactness and compactness homogeneity. For difficult to compact and particularly tight corner. The sand compaction to high (usually ≥ 85) requirements, good uniformity, reduce sand gap, with particular attention to the core damage repair should be in place, not because of the existence of local osteoporosis repair.
3, attention should be paid to the gating system and riser, should avoid the casting and mould to produce local overheating. The design of gating system should avoid the ingate directly punching mould wall.
4, appropriate to reduce the pouring temperature, casting speed and pouring height, the so-called "reduced" mean in the premise that can cast into casting, reduce metal delta forces on sand and the physical and chemical effects. Note that reducing the pouring height, reducing the height and pouring cup height, to reduce the metal liquid dynamic pressure, static pressure and heat shock on the casting stress. The tooth casting, wall is not thick, but high casting temperature, increase heat time Steel Chau and cavity surface, pouring molten steel on the cavity of the dynamic pressure and static pressure, to create the conditions for the mechanical penetration.

Excavator bucket teeth porosity defects

1/4/2019 1:57:01 PM

In the cut excavator bucket teeth found around the pores, while fighting tooth cavity also found holes.
Casting bucket tooth pores can be divided into precipitation of porosity, pore invasive pores and reaction, and fighting tooth and adapter shrinkage, shrinkage in the formation of mostly accompanied by precipitation of gas porosity and shrinkage, shrinkage can said to be associated. If the alloy containing gas is too high, or the liquid metal filling process gas too intrusive, would exacerbate the formation of the craters or pores. Through the analysis of bucket teeth cut, you can see the pores are randomly distributed, and large holes, mostly spherical and spherical group, we can conclude that this is essentially intrusive stomatal pores.

Excavator is introduced

1/4/2019 1:33:29 PM

Excavator, also called excavating machinery, is a mining above or below the machine for the surface of materials with a bucket of earth moving machinery, transport and loading or unloading of vehicles to the yard.Excavator material is mainly coal, soil, sediment and pre loose soil and rock. In recent years as the development of construction machinery,relatively fast development of excavator, excavator has become one of the most important engineering machinery in engineering construction. The three most important parametersof excavator: operating weight (mass), the engine power and bucket capacity.

Foundry quality means that the high quality casting mould

1/4/2019 1:29:21 PM

For foundry, high quality die means high quality castings, it means lower costs, higher output and profits.
At present, the development of domestic mold industry is very fast, only aluminum alloy gravity casting mold production factory is not hundreds, but with the development of automobile industry and the influx of foreign capital, mold production factory in both scope and technical strength also is in grow with each passing day. With the popularization and application of CNC machining equipment, processing level of mold industry and foreign countries has not much difference, many mold factory has advanced detection equipment, but our management, design concept, management philosophy and foreign counterparts than there are gaps, mould material and heat treatment strengthening method is also far behind the developed countries. The present situation for casting mold production factory, have practical experience, engineering and technical personnel understand the mold manufacturing and to understand the casting process is very lack, and die debugging and verification process is a Hom mold manufacturing process will take, because the success of mold and mature process is casting factory, many of today's technology weak desired.
Application of standardized mold and mold standard parts is an inevitable trend of the future development of die industry. In the late of the aluminum alloy gravity casting is even more so. Only the implementation of the standardization of mold, to standard mold factory, mold to mold factory to provide high quality and low price standard is possible. At the same time, application of standardized mold and mold standard parts, will make the foundry is easier to monitor the quality of mold, the mold maintenance and maintenance more convenient. The use of mold standard parts, mould industry will help to change the current multi variety, small batch production scale, production efficiency, reduce costs, improve productivity.
In short, precise size, high production efficiency, convenient use and maintenance of die casting industry is the industry and the pursuit of forever.

Precision casting of the future

1/4/2019 1:28:15 PM

Precision casting and lost wax casting, its product precision, complex, close to the final shape of the part, not processed or rarely processing is used directly, so the investment casting is a near net form of advanced technology.
Ancient China: Prince Wu Ding, copper ban, bronze and so on, are casting. Since twentieth Century 40 years the investment casting used in industrial production, half a century has been a faster pace. Especially the European and American countries develop rapidly. Now the investment casting used in aviation, Ordnance Department, used in almost all industrial sectors, especially in electronic, petroleum, chemical, energy, transportation, light industry, textile, pharmaceutical, medical equipment, pumps and valves and other departments. In recent years, rapid development in china.
