    摘要: This invention has provided a manufacturing method of semi-finished piston with inner cooling channel through liquid extrusion process, including the following steps: a) produce a wear-resistant cast iron ring with coupling hooks and a common salt and corundum dissoluble core with convex edges; b) fix the wear-resistant cast iron ring in the casting moulds after being aluminized; c) fix the dissoluble core after being pre-heated on the wear-resistant cast iron ring with coupling hooks and convex edges; d) fill in the casting mould with aluminum alloy liquid, compressing and molding. The dissoluble core can be accurately fixed in the casting mould through coupling hooks and convex edges. When the semi-finished piston has been manufactured into finished product, it shall be characterized by high compactness and high mechanical property resulted from liquid extrusion technology. Meanwhile, because of the cooling channel, the temperature in the combustion chamber of the head and ring groove is reduced, the load capacity of the piston is greatly improved, and the manufacturability becomes better.

    摘要: The present invention has provided a welding forged steel single piece piston and its manufacturing methods. A semi-finished head and a semi-finished skirt are forged respectively; the semi-finished head and semi-finished skirt are heat-treated respectively; rough machining is carried out respectively to the semi-finished head and the semi-finished skirt, and a face of weld between the two adjacent ring grooves is higher than the one under the combustion chamber; the head and the skirt are welded together through friction welding; an annular groove, a combustion chamber, a ring groove, a pinhole, an outer annulus and oil inlet/outlet holes are manufactured respectively; and the surface of the piston is phosphorized and graphitized. Compared with one-piece forged piston, it has better processing technology, because the head and skirt are forged respectively and then welded together. Over-all structural rigidity of the piston has been increased, and distortion of the ring groove in high temperature is slight because the cooling oil recess is sealed through welding. As the annular groove is located on the upper part of skirt, the weight of body of the piston is lowered and this kind of structure can accelerate engine oil returning on, decrease the clearance between the piston and the cylinder and reduce the engine oil consumption.

    摘要翻译: 本发明提供了一种焊接锻钢单片活塞及其制造方法。 分别锻造半成品头和半成品裙; 半成品头和半成品裙分别进行热处理; 分别对半成品头和半成品裙部进行粗加工,两个相邻环形槽之间的焊接面高于燃烧室下面的焊接面; 头部和裙部通过摩擦焊接焊接在一起; 分别制造环状槽,燃烧室,环槽,针孔,外环和油入口/出口孔; 并且活塞的表面被磷化并石墨化。 与单件锻造活塞相比,它具有更好的加工技术,因为头部和裙部分别锻造,然后焊接在一起。 增加了活塞的全部结构刚度,并且由于冷却油凹部通过焊接而密封,高温环形槽的变形很小。 当环形槽位于裙部上部时,活塞体的重量降低,这种结构可以加速发动机油的返回,减少活塞与气缸之间的间隙,减少发动机机油消耗。
