Description
Technical Field
The invention relates to the technical field of titanium material production, in particular to a method for connecting a titanium material and a titanium material in a cold rolling, stretching and straightening unit.
Background
In a cold rolling stretching straightening unit, two rolls of titanium materials are required to be connected together for continuous production, at present, the titanium materials are mainly connected with each other through a manual riveting mode, the connection efficiency of the connection mode is low, the manual strength is high, and long waste titanium materials are easy to generate.
Disclosure of Invention
The invention aims to solve the technical problem of providing a method for connecting titanium materials in a cold rolling, stretching and straightening unit, which has higher efficiency and low manual strength.
The invention solves the technical problem of adopting the method for connecting the titanium material and the titanium material in the cold rolling stretching straightening unit, the method for connecting the titanium material and the titanium material adopts a lap welder to connect, and the welding parameters during the connection are as follows:
| titanium material thickness (mm) | Current (A) | Welding pressure (Mpa) | Rolling compaction (Mpa) |
| 0.4 | 12800 | 0.35 | 0.35 |
| 0.6 | 13800 | 0.35 | 0.35 |
| 0.8 | 14400 | 0.4 | 0.45 |
| 1 | 15200 | 0.4 | 0.45 |
| 1.2 | 16000 | 0.4 | 0.45 |
| 1.5 | 16800 | 0.45 | 0.5 |
| 1.8 | 18000 | 0.45 | 0.5 |
| 2 | 18800 | 0.45 | 0.5 |
Wherein, the welding of the titanium materials with different thicknesses is carried out according to the welding parameters of the titanium materials with relatively thicker thickness.
Furthermore, when the titanium materials with different thicknesses are welded, the titanium material with relatively thicker thickness is a first titanium material, the titanium material with relatively thinner thickness is a second titanium material, and the thickness difference between the first titanium material and the second titanium material is less than half of the thickness of the second titanium material.
Furthermore, when the titanium material is connected with the titanium material, the lapping amount on the operation side is 2mm, and the lapping amount on the transmission side is 2.7 mm.
The invention has the beneficial effects that: in the cold rolling stretching straightening unit, the titanium material and the titanium material are connected by adopting a lap welder, and welding parameters during connection are strictly controlled, so that the titanium material and the titanium material are connected by welding under the condition that protective gas does not need to be filled, the connection efficiency and the yield are obviously improved, the manual strength is reduced, and the popularization is facilitated.
Detailed Description
The invention relates to a method for connecting titanium materials in a cold rolling stretching straightening unit, which is characterized in that the titanium materials are connected by adopting a lap welder, and welding parameters during connection are as follows:
| titanium material thickness (mm) | Current (A) | Welding pressure (Mpa) | Rolling compaction (Mpa) |
| 0.4 | 12800 | 0.35 | 0.35 |
| 0.6 | 13800 | 0.35 | 0.35 |
| 0.8 | 14400 | 0.4 | 0.45 |
| 1 | 15200 | 0.4 | 0.45 |
| 1.2 | 16000 | 0.4 | 0.45 |
| 1.5 | 16800 | 0.45 | 0.5 |
| 1.8 | 18000 | 0.45 | 0.5 |
| 2 | 18800 | 0.45 | 0.5 |
When the titanium materials with different thicknesses are welded, welding parameters of the titanium materials with relatively thicker thicknesses are carried out, for example, when the titanium materials with the thickness of 0.4mm and the titanium materials with the thickness of 0.6mm are welded, the welding parameters are carried out according to the parameters of the titanium materials with the thickness of 0.6mm, and when the titanium materials with the thickness of 1.2mm and the titanium materials with the thickness of 1.5mm are welded, the welding parameters are carried out according to the parameters of the titanium materials with the thickness of 1.5 mm.
In order to ensure the welding effect, when titanium materials with different thicknesses are welded, the titanium material with relatively thicker thickness is a first titanium material, the titanium material with relatively thinner thickness is a second titanium material, and the thickness difference between the first titanium material and the second titanium material is less than half of the thickness of the second titanium material. Furthermore, when the titanium material is connected with the titanium material, the lapping amount on the operation side is 2mm, and the lapping amount on the transmission side is 2.7 mm.
In order to ensure the continuous production of titanium materials in a cold rolling stretching straightening unit, after the titanium materials and the titanium materials are welded, the welding seam is threaded and pulled and corrected, the pulling and correcting elongation is set according to 0.1 percent, the pulling and correcting tension is set according to 20 percent of the conventional tension, and the coiling and uncoiling are set according to 50 percent of the conventional tension, so that the strip breakage in the process of threading the welding seam of the titanium materials is avoided.
In conclusion, in the cold rolling, stretching and straightening unit, the titanium material and the titanium material are connected by the lap welder, and welding parameters during connection are strictly controlled, so that the titanium material and the titanium material are connected by welding under the condition of not being filled with protective gas (argon), thereby obviously improving the connection efficiency and the yield, reducing the manual strength and being beneficial to popularization.
