Straightening device for lead ingot of electrolytic lead

The utility model relates to the lead smelting technical field, particularly to a straightening device for a lead ingot of electrolytic lead in the conveying process of the lead ingot. A supporting slide is formed between secondary slides which are formed on the bilateral sides respectively; the supporting slide is fixed on a frame beam in a welding mode; the frame beam is arranged behind a supporting platform. According to the straightening device for the lead ingot of the electrolytic lead, the supporting slide serves as the middle support of the lead ingot when the lead ingot slides down; a cooling device is added in the conveying process of the lead ingot and accordingly the cooling speed of the lead ingot is improved, the lead ingot is cooled when being conveyed to a driven chain wheel, the size is reduced, and accordingly the demoulding is easy and meanwhile the hardness of the lead ingot is increased due to spray cooling and accordingly the bending of the middle of the lead ingot due to the fact that the hardness of the lead ingot is not enough is not caused when the lead ingot slides down; the structure is simple, the installation is convenient, and the bending deformation of the lead ingot is improved so as to enable the straightness of the lead ingot to reach more than 99%.
