Abstract

The invention discloses a technique based on static pressure casting half shafts, and relates to the technical field of static pressure casting. The invention includes the following process: SS01 riser position setting, SS02 setting core heads at both ends of the top plate, SS03 feeding at position A in the middle of the half shaft, SS04 feeding at position C in the middle of the half shaft, SS05 casting mud core wall thickness Control, SS06 pre-embeds the combined core bone when making the core. The invention adopts the KW static pressure molding line to obtain a mold with high compactness and uniformity, and the product size accuracy is high; through the design of cold iron with riser and hot riser solidification and feeding technology, the adjustment of solidification has been achieved. The combined effect of sequence and feeding heat joints; the use of combined mandrel instead of welding reduces the welding process, improves the rigidity of the mandrel, and eliminates the problem of mandrel deformation.

Description

Technical field

[0001] The present invention belongs to the field of static pressure casting techniques, particularly a process involving a semi-axis based on a static pressure casting. Background technique

[0002] With the steady rapid development of the economy, today China has played weightlifier in global economic and international trade. China's casting technology has continued to advance with the development of the economy, and is now the world's largest casting production, use and trading countries.

[0003] JCB is one of the world's five major construction machinery and agricultural machinery manufacturing companies. The box, integrally driven bridge, and segment-driven bridges developed by JCB, a total of more than 50 products. The JCB series half-axis has a total of 9 kinds of products, and the casting is single between 40-80 kg, the minimum wall thickness is 10mm, the length is up to 900 mm. Moreover, there is mainly half-axis wall thickness, dispersion of the isolati...
