Description

technical field [0001] The invention relates to the field of bending devices, in particular to a first bending device for bending resistance pins. Background technique [0002] Resistors are widely used in electronic products. Resistors act as voltage dividers and shunts in circuits. Both AC and DC signals can pass through resistors. Capacitors are widely used in circuits for blocking, coupling, filtering, and energy conversion. The resistors used in electronic products are mainly: chip resistors and resistors with pins. The resistors with pins are divided into pins at one end of the device and pins at both ends of the device. Resistors with pins at both ends need to be pin-shaped. Axial components are usually bent on both sides at the same time. In the prior art, the pins of resistors are usually bent directly by hand based on the operator's feeling and experience. Forming, this method is difficult to ensure the consistency of the resistor pin bending, which has a great im...

Problems solved by technology

Resistors with pins at both ends need to be pin-shaped. Axial components are usually bent on both sides at the same time. In the prior art, the pins of resistors are usually bent directly by hand based on the operator's feeling and experience. Forming, this method is difficult to ensure the consistency of the resistor pin bending, which has a great impact on the life of the resistor

[0003] Chinese patent application CN206326047U discloses a resistance / capacitance pin bending forming device, which aims to provide a mold for precisely forming resistance / capacitance pins at one time and avoiding repeated bending of the pins. It is realized through the following technical solutions: A slide plate connected by a slide shaft is arranged on the bottom plane plate of the L-shaped base. Extending towards the direction of the scale, the steps are arranged in a linear array from small to large, and each step is made with a groove similar to the shape of the resistance / capacitance element pin; the pin is placed on the corresponding step to prevent the resistance / capacitance from sliding relative to each other On the groove of the step; the slide plate slides relative to the bottom plane plate of the L-shaped base under the drive of the screw screw handle, and the relative distance is read through the scale vertically fixed on the vertical plate of the L-shaped base. Resistor / capacitance pins with different pin pitches are formed on the steps. The advantage of this device is that it improves the consistency of the resistance pin bending and improves work efficiency, but problems such as burrs still occur when bending the resistance pins. , it will still affect the service life of the resistor, and it is not suitable for more types of resistors, and the practicability is low
