Automatic welding machine of gold sample tube

Abstract

The invention discloses an automatic welding machine for a gold sample cell, which comprises an argon chamber (1), an argon arc welding machine (2), a program controller (3); an admitting port (4) and a vent port (5) are arranged in the argon chamber; a turnplate (6) is arranged in the argon chamber; the turnplate is connected with a driving motor (7); a plurality of gold tube locating holes (8) are formed on the turnplate; each gold tube locating hole is positioned on a circumference which takes the rotating center of the turnplate as the center thereof; an infrared emitter (9) and an infrared receiver (10) are respectively arranged in the argon chamber on the two sides right above the gold tube locating holes; the tungsten welding pin (11) of the argon arc welding machine is arranged in the argon chamber; the end part of the tungsten welding pin is arranged right above the gold tube locating holes; and the program controller is connected with the argon arc welding machine, the driving motor, the infrared emitter and the infrared receiver. The method adopts automatic welding, so that the welding efficiency is high, the success rate of welding is 100%, the welding line is even and smooth, the welding time is short, and the maximum heating temperature of the sample does not exceed 40 DEG C.

Description

technical field [0001] The invention relates to a gold sample tube automatic welding machine for gold tube welding used in the study of hydrocarbon generation kinetics in the field of petroleum and natural gas geochemistry. Background technique [0002] At present, in the study of hydrocarbon generation kinetics in the field of petroleum and natural gas geochemistry, it is necessary to seal the organic matter in the formation in a gold tube, and then pressurize and heat the gold tube containing the sample to study the amount of oil and gas generated. At present, both at home and abroad, argon arc welding machines are used to manually weld gold tubes. Manual welding has the following disadvantages: 1. The wall thickness of the gold tube is only 0.2 mm, so the technical requirements for the operator are very high. If you are not careful, the gold tube will be burned through and scrapped. Even for skilled operators, the success rate is low. It will not be higher than 80%; 2. T...

Problems solved by technology

Manual welding has the following disadvantages: 1. The wall thickness of the gold tube is only 0.2 mm, so the technical requirements for the operator are very high. If you are not careful, the gold tube will be burned through and scrapped. Even for skilled operators, the success rate is low. It will not be higher than 80%; 2. The moment of welding will cause the gold tube to generate high temperature. If the time is too long, the chemical composition of the organic matter in the sample will change. If the time exceeds 1 second or multiple welding, the sample may be scrapped, and the manual welding time is difficult to be accurate. control
