Novel steel drum welding seam flattening device

Abstract

The invention relates to the technical field of steel drum manufacturing, and discloses a novel steel drum welding seam flattening device. The device comprises a flattening mechanism and a conveying mechanism arranged below the flattening mechanism, a seam searching mechanism is arranged on the conveying mechanism and comprises a seam searching frame, a rotating part, a lifting part and a seam searching part, and the rotating part, the lifting part and the seam searching part are arranged on the seam searching frame. The seam searching part is arranged on the flattening mechanism on the seam searching frame, a seam searching sensor is arranged on the seam searching part and electrically connected with the rotating part and the lifting part, the flattening mechanism comprises a rack and two gripper assemblies arranged above the rack, a synchronous part is connected between the two gripper assemblies, and the synchronous part controls two sets of grippers to move in the same direction. Positioning barrels are arranged at the position, located at the two sides of the conveying mechanism, of the rack, and a correcting mechanism is arranged below the two positioning barrels. The device has the following advantages and effects that the position of a welding seam can be accurately found and the welding seam can be flattened, and the technical effects of accurately positioning the welding seam and preventing extrusion deformation are achieved.

Description

technical field [0001] The invention relates to the technical field of steel drum manufacturing, in particular to a novel steel drum welding seam flattening device. Background technique [0002] Steel drum resistance welding is to press the drum to be welded between the two electrodes, and use the current to heat it to a melting or plastic state by using the resistance heat generated by the current flowing through the contact of the drum and the adjacent area. After the power is turned off, A method of bonding metals to form a strong joint under continued pressure. When the nugget begins to form, a greater portion of the current will be forced to flow through the crimping zone (plastic welding ring) around it due to the increased resistance of the melting zone. The area is melted one after another, and the nugget continues to expand, but the diameter of the nugget is restricted by the diameter of the electrode end face. Excessive expansion of the nugget will make it difficu...

AI Technical Summary

Problems solved by technology

The present invention does not align the weld seam before seam pressing, and this method is prone to deformation of the steel drum due to pressure deviation, and the function of synchronous feeding and unloading cannot be realized in this invention. At the same time, in the During the welding seam flattening process of the steel drum, since the upper end of the steel drum does not protect the interior of the steel drum, the steel drum is easily deformed
