Problems solved by technology
In the prior art, the bending and forming of bulk resistance is mainly realized by hand or simple tooling. During the bending process, the bent resistance pins are irregular, which is inconvenient for automatic insertion, and the deformed resistance pins cannot be fixed during bending. Effective correction, the resistance body is easy to be strained, the coating of the resistance pin is damaged, and the defects of low efficiency and poor product quality consistency

Embodiment
[0028] Embodiment, the working process of the present invention is as follows:
[0029] refer to figure 1 , image 3 , Figure 4 , Figure 6 , 1. First place the lower mold 21 on the bottom plate 41, and limit the position of the lower mold 21 by adjusting two stoppers 32, so that the resistance positioning groove 211 on the top of the vertical plate of the lower mold 21 is pressed against the pin of the positioning device 3. The tight block 22 is aligned; the lower mold 21 is fixed between the limit block 32 and the clamping cylinder 31 with the clamping cylinder 31 of the positioning device 3; the relative position of the two jaws 12 is adjusted by the two driving rods of the double cylinder 11, Make the forming wheels 122 of the two jaws 12 reach the bending position of the resistance pin.
[0030] refer to figure 1 , figure 2 , image 3 , Figure 6 2. Place the resistance to be bent into the resistance positioning groove 211 on the top of the vertical plate of the...

The invention discloses a bulk resistor straightening and bending mechanism comprising a clamping jaw mechanism, a lower mold assembly, a positioning device and a power module. A pin tight pressing block is driven by a vertical cylinder of the lower mold module to tightly press the roots of resistor pins in a resistor positioning groove, and therefore the bending size of the resistor pins is ensured, and a resistor body is protected and cannot be pulled broken during bending. A duplex cylinder of the clamping jaw mechanism is driven by a power head of the power module to move downwards, forming wheel wire grooves in the clamping jaw mechanism are meshed with the resistor pins, and along with downward movement of the clamping jaw mechanism and forming wheels, while the pins of a resistor are corrected through the wire grooves in the forming wheels, the pins at the two ends of the resistor are bent by 90 degrees at the same time. The bulk resistor straightening and bending mechanism hasthe beneficial effects of being simple in structure, neat in resistor pin bending, convenient and rapid to use and high in work efficiency.
Description
technical field [0001] The invention relates to the technical field of processing electronic components, and is used for bending and forming pins of electronic components, in particular to a bulk resistance straightening and bending mechanism. Background technique [0002] Resistors, as important electronic components for dividing voltage and current in circuits, are widely used in electronic products. In order to meet the process requirements of resistors in the PCB insertion process, it is necessary to bend the resistors into the expected shape and size. Especially in some application fields with special process restrictions, it is necessary to bend bulk resistors. Most of the bulk resistors are supplied by professional manufacturers. When the resistors come in, the pins are in a state of extrusion and deformation during transportation. In the prior art, the bending and forming of bulk resistance is mainly realized by hand or simple tooling. During the bending process, t...
