Embodiment Construction

[0015] The following combination figure 1 , the content of the present invention will be described in detail through specific embodiments. The titanium metal piston includes a piston crown with a concave arc crater, a piston pin hole tube seat, a cylindrical piston skirt and a piston pin hole tube, and a pair of piston pin holes are symmetrically arranged on the piston skirt, and it is characterized in that: the titanium metal piston It is welded by the piston top, piston pin hole tube seat, piston skirt and reinforcing ribs. The piston top is welded to one end of the piston skirt, and a pair of piston pin hole tubes are relatively welded in the piston skirt. The piston pin hole tube is supported by the piston pin hole tube. Welded on the inside of the piston pin hole.

[0016] The manufacturing method of this titanium metal piston comprises the following steps:

[0017] Step 1) Cutting and stretching titanium metal rods into piston top blanks, using isothermal die forging p...

Abstract

A titanium piston comprises a piston top provided with an arc-shaped concave pit, a piston pin hole tube seat, a cylindrical piston skirt and piston pin hole tubes. A pair of piston pin holes are symmetrically formed in the piston skirt. The titanium piston is characterized in that the titanium piston is formed by the piston top, the piston pin hole tube seat, the piston skirt and reinforcing ribs through welding; the piston top is welded to one end of the piston skirt; the pair of piston pin hole tubes are oppositely welded in the piston skirt; and the piston pin hole tubes are welded to the inner sides of the piston pin holes through piston pin hole tube supports. By the adoption of the titanium piston, the defects that an existing manufacturing technique is tedious, low in efficiency and high in manufacturing cost are fundamentally overcome, the efficiency of an internal combustion engine can be effectively improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the manufacturing field of engine parts, in particular to a titanium metal piston, which is mainly suitable for high-power internal combustion engines. Background technique [0002] In an internal combustion engine (a general term for gasoline engine, diesel engine, and gas engine), the piston is called the "heart" of the internal combustion engine. It is a key moving part that bears repeated alternating loads under high temperature and high pressure friction. It is one of the parts with the highest working intensity. One, the working environment is the worst. The top of the internal combustion engine piston is in contact with high-temperature and high-pressure gas, so the working temperature is high and the heat load is large; its skirt is in contact with the cylinder wall, in a state of high-speed motion, and has poor lubrication conditions. Generally, the temperature at the top of the piston can reach above 300°C. According...
