A ribbon bending mechanism, device and stringer

Abstract

The invention relates to the field of weld band bending and specifically relates to a welding band bending mechanism. The welding band bending mechanism comprises a lower tool rest and an upper tool rest which is movable up and down, and a first blade and a second blade which are parallelly arranged on the lower tool rest, and a third blade and a fourth blade which are parallelly arranged on the upper tool rest; an elastic component is disposed between the first blade and the lower tool rest, and moves down to the bottom end under the pressure of the fourth blade, and moves up and is flush with the second blade under the elastic force of the elastic component. The invention also relates to a welding band bending device and a string welding machine. The invention has the beneficial effectsthat the invention has a simple structure by designing a welding belt bending mechanism as compared with the prior art. Through the four blades set up and down, the welding band is bent and the subsequent maintenance and replacement are also facilitated. And by the first blade that can be moved up and down, when the already-bending solder ribbon is removed, there is no blocking effect on the movement of the solder ribbon, and the movement is smooth.

Description

technical field [0001] The invention relates to the field of welding ribbon bending, in particular to a welding ribbon bending mechanism, device and stringer. Background technique [0002] The ribbon bending technology of the existing stringer welder mostly uses stepped upper bending knives and lower bending knives to press the welding ribbons, but there are the following disadvantages: the tool structure is complicated, the manufacturing cost is high, and the tool wear It is inconvenient to grind afterward, and the facade between the two working surfaces of the bending knife has a certain blocking effect on the movement of the welding strip after bending. [0003] Therefore, the research and development of a bending mechanism and corresponding stringer with simple structure, low manufacturing cost, convenient grinding after wear, and no blocking effect on the movement of the ribbon after bending is a key research for those skilled in the art. one of the problems.
