Description

V method casting intelligent production line

Technical Field

The utility model belongs to the casting field relates to V method casting intelligent production line.

Background

The demand of the forklift in the domestic market or the international market is stronger nowadays, the production capacity of the counterweight castings and the demand of a main engine plant have larger gaps, and the counterweight castings face larger supply pressure, so that the main factors restricting the production capacity are just like the following points:

firstly, the high-strength casting adopts a green sand production process, the casting technology and equipment are relatively lagged behind, the mechanization degree is low, the labor productivity is low, the technical level and equipment are more prominent and are only limited to a few backbone enterprises, and the advanced and automatic technology and equipment are generally realized in developed countries.

Secondly, the quality of the produced product is low, the precision is poor, the requirement of a new technology of a new process can not be met, and the process level can not be in the same day as foreign countries.

And thirdly, the environmental pollution is serious, the energy consumption is large, extensive production is realized, foreign casting enterprises pay attention to the importance of environmental protection while improving the casting technology, and domestic casting enterprises are relatively deficient in the aspect.

And fourthly, the development scale is small, the economic benefit is poor, although the increase speed of manufacturers in the casting industry is accelerated every year, the manufacturers are mostly workshop-type small manufacturers, the scale is small, and the technical and manpower investment is small, so that considerable economic benefit is difficult to obtain.

Traditional foundry, traditional production, is severely challenged.

The V-method casting is a new generation physical forming method following mechanical forming and chemical forming, and the basic principle is as follows: filling single dry sand into a sand box with an exhaust chamber, slightly vibrating and compacting, vacuumizing the sand mould with a molding surface and a plastic film coated on the back surface of the sand box, molding the casting mould by utilizing the pressure difference between the inside and the outside of the sand box, stripping and assembling the mould, and pouring molten metal in a vacuum state

Compared with the traditional sand casting, the casting cast by the V method has good surface smoothness, clear outline, high dimensional precision and less machining allowance, the quality of the casting cast by the V method can be reduced by 6-8 percent, and the riser of the casting can be reduced because the molten metal is cooled in the cavity at a lower speed, which is beneficial to feeding metal, thereby improving the utilization rate of the metal.

The reuse rate of used sand cast by the V method can reach about 95 percent, raw materials are greatly saved, the pattern is not worn because the pattern is not in direct contact with casting sand, a wood pattern can be used under the condition of single small batch or trial production, the cost of the pattern can be greatly saved, and metal models can be reused after batch production.

The V-method casting production line equipment is relatively simple, mainly comprises a molding, sand treatment and vacuum system, and additionally needs a special sand box, so that a sand mixer and other auxiliary equipment required by other molding methods can be omitted, the investment cost is low, the use and maintenance amount of the equipment is less, the V-method casting production cycle is short, the process is simple and convenient, the operation is easy, the quality management is more convenient, common workers can perform on duty production only through short-term training, and practice proves that the V-method casting production line equipment is an economic and environment-friendly novel casting method.

The V-method counterweight casting is a key casting necessary for forklifts and engineering machinery in China and a key matching piece with large market demand for international forklifts and engineering machinery, and the demand for the V-method counterweight casting is increased rapidly, so that the production capacity of the V-method counterweight casting is improved as soon as possible, and the problem that the domestic and foreign market demands are urgently needed to be faced and solved is met.

Most of the existing market is a stall-type production mode, the occupied area is large, unified planning and management are lacked, and the field working environment is dirty and poor.
