Description

Technical Field

[0001] The utility model relates to the field of resistance wire bending tooling, in particular to a resistance wire bending tooling for processing bridge wire resistors. Background Art

[0002] The bridge wire resistor needs to be bent into a spring shape during processing, and a bending tool is required during the bending process.

[0003] At present, a Chinese utility model with the announcement number CN219425506U discloses a bending tool for resistance wire processing, including: a bottom plate; a fixed plate, the fixed plate is fixed to one side of the top of the bottom plate, one side of the fixed plate is slidably connected to a movable plate, and the bottom of the movable plate is rotatably connected to a driving plate; a connecting plate, the connecting plate is detachably mounted on the bottom of the driving plate, the bottom of the connecting plate is fixedly connected to a fixed rod, and a limited position hole is provided at the lower end of the fixed rod; a driving member for controlling the rotation of the driving plate. The bending tool for resistance wire processing provided by the utility model can make the resistance wire evenly and comprehensively wound around the outer surface of the fixed rod through the movement of the fixed rod, thereby improving the smoothness and stability of its bending processing, and the fixed rod is detachably connected, so that the staff can replace the fixed rod according to the size of the resistance wire bending, thereby meeting the bending processing of resistance wires of different diameters.

[0004] To sum up, although the device can bend resistance wires of different diameters, there are still certain problems in its use. First, the way the bending tool adjusts the bending diameter of the resistance wire is to replace the fixed rod, and the fixed rod needs to be disassembled during replacement, which will waste time. Secondly, since the size of the fixed rod is also fixed, the diameter of the resistance wire processing depends on the diameter of the fixed rod. It is easy for the fixed rod to fail to meet the required diameter size, and its applicability is poor. Utility Model Content
