Problems solved by technology
At present, the common surface mount process has high requirements on the precision of the lead forming. If the lead is not bent in place or uneven, it will cause defects such as false soldering and missing soldering. Moreover, the shape of the lead is complex and cannot be formed in place at one time. The pins are bent multiple times, and an additional step of cutting the feet is required

The invention discloses a hand-held component pin forming device. The hand-held component pin forming device comprises a fixed caliper, a movable caliper capable of getting close to or away from the fixed caliper, an upper die arranged at the end of the fixed caliper and a lower die arranged at the end of the movable caliper, the fixed caliper is hinged to the movable caliper, one of the upper die and the lower die is provided with a protrusion, the other one is provided with a groove, the side part of the groove is provided with a plurality of fixing pieces for fixing pins, the positions between the adjacent fixing pieces are used for containing the pins, the side parts of the fixing pieces are used for abutting against the roots of the pins, the side surface of the protrusion is a shearing blade, and the top surface of the protrusion is matched with the bottom surface of the groove to press the pins. By using the hand-held component pin forming device, the pin forming and shearing effects of components can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of lead forming, and more specifically relates to a hand-held component lead forming device. Background technique [0002] In the prior art, in the design of power electronic products, in-line MOS transistors (metal-oxide-semiconductor metal-oxide-semiconductor field-effect transistors) or diodes are often used for reasons such as structural layout and heat dissipation design. Changing to the use scenario of surface mount components, at this time, it is necessary to solve the problem of pin forming of in-line components. At present, the common surface mount process has high requirements on the precision of the lead forming. If the lead is not bent in place or uneven, it will cause defects such as false soldering and missing soldering. Moreover, the shape of the lead is complex and cannot be formed in place at one time. If the pins are bent multiple times, an additional step of cutting the feet is required. ...
