The invention discloses a steel liner arc bending machine which comprises a main frame body; a power device is arranged in the main frame body; a working table is arranged on the main frame body; a first compression roller mechanism, a second compression roller mechanism and a third compression roller mechanism are arranged on the working table; the first compression roller mechanism is in transmission connection with the power device through a first chain, and the second compression roller mechanism is in transmission connection with the first compression roller mechanism through a second chain; when the device is used, the power device is started, and the first compression roller mechanism, the second compression roller mechanism and the third compression roller mechanism are matched to bend a straight-strip-shaped steel liner into an arc shape, so that the machining mode of manual arc bending through fire heating is changed, and the manufacturing efficiency is improved; the precision of the arc radius is improved, so that the arc radius is more tightly attached to a steel structure part, and the full penetration qualification rate of a welding seam is ensured.
Description
technical field [0001] The invention relates to the field of arc bending machines, in particular to a steel liner arc bending machine. Background technique [0002] In steel structure engineering, full-penetration butt welds are used when welding round pipes or full-penetration welds are used when welding ring plates of round pipes. In order to facilitate welding, steel liners are usually added and single-sided welding is used. Formed plan. Because the round pipe is a curved structure, and the steel liner on the market is a straight strip, it is not suitable for the use of this kind of curved structure of the round pipe. Before making this equipment, the scheme of manual arc bending with warming fire is usually adopted, the production efficiency is low, and the radius of the arc bending is quite different, which is not conducive to close to the steel structure parts, and the pass rate of full penetration of the weld seam is low. It costs a lot to repair it. In order to ov...
