The invention discloses a lead pot for adding lead to a lead-forming lead wire in a quantified manner. The lead pot for adding lead to the lead-forming lead wire in a quantified manner comprises a rack and a pot body fixed to the rack. A heater is arranged in the pot body. An opening is formed in the top of the pot body. One or more lead-discharging nozzles are formed at the bottom of the pot body. A lead valve is connected to each lead-discharging nozzle correspondingly. A lead wire guide-in mechanism is arranged on the rack. The lead wire guide-in mechanism comprises a set of lead wire conveying rollers and a leading pipe, wherein the set of lead wire conveying rollers are arranged in sequence along the conveying direction of the lead wire. The set of lead wire conveying rollers comprisea driving roller and a driven roller which are arranged in a spaced manner. The driving roller is driven to rotate by a motor. The lead wire enters the leading pipe under the clamping and conveying of the driving roller and the driven roller. The discharging end of the leading pipe extends into the opening of the top of the pot body so that the lead wire can be led into the pot body. According tothe lead pot for adding lead to the lead-forming lead wire in a quantified manner, the set of lead wire conveying rollers are driven to move by the motor; the strip-shaped lead wire is driven to be led into the pot body; in addition, the length, led into the pot body, of the lead wire can be controlled through control over the rotating speed of the motor; and thus quantified lead melting is achieved.
