Embodiment 1

[0017] Example 1: A method for correcting the drape and rigidity of the copper starter sheet. First, push the copper seed plate on the conveyor into the embossing device with a cylinder. The embossing device includes a pair of nip-in rollers and three pairs of embossing After the copper seed plate passes through three pairs of embossing rollers, the same depth of embossing will be rolled on the front and back sides to increase the rigidity of the copper seed plate and control the deformation of the copper seed plate to arch deformation in the length direction; secondly, The embossed copper seed plate is sent to the rod nailing device, and the copper seed plate is made into a copper initial plate after being threaded and nailed; after that, the copper initial plate is sent to the beating and shaping device, and the beating and shaping device The device simulates the action of manual slapping and shaping. The bottom of the copper starter is slapped horizontally and the upper part...

Abstract

The invention relates to a method for correcting the pendency and rigidity of a copper starting sheet, and belongs to the technical field of non-ferrous metallurgy. Firstly, the copper starting sheet on a conveyer is pushed into a pattern pressing device through an air cylinder. Secondly, the patterned copper starting sheet is conveyed into a rod penetrating and lug nailing device. Thirdly, the copper starting sheet is conveyed into a patting shaping device which simulates the motions of manual patting shaping to carry out transverse patting shaping on the bottom of the copper starting sheet and vertical patting shaping on the upper half portion of the copper starting sheet. Finally, the copper starting sheet is conveyed to a storage frame. The method can improve the grooving rate of the copper starting sheet, reduce the phenomenon of point discharge, and simulate the electrolysis state of the copper starting sheet during patting shaping. The copper starting sheet is always in a suspension state and directly conveyed onto the storage frame after being shaped, deformation caused during transportation can be reduced, and it is guaranteed that the pendency is not changed before grooving. In addition, the method for correcting the pendency and rigidity of the copper starting sheet is simple in machining process, good in effect, low in cost and capable of realizing production automation extremely easily.

Description

technical field [0001] The invention relates to a method for correcting the drape and rigidity of copper starter plates, belonging to the technical field of nonferrous metal smelting. Background technique [0002] In the production process of traditional copper electrolytic refining, it is necessary to process and manufacture copper starter as the cathode. The drape of the copper starter will directly affect the quality of cathode copper and various technical and economic indicators of electrolysis. [0003] Copper starter plate is composed of three parts, namely copper seed plate, conductive rod and lifting lug, among which the copper seed plate is a high-purity copper sheet obtained by electrolysis. Due to the defects of the processing technology and the improper operation in the process of processing and transportation, the copper seed plates produced have different degrees and types of bending deformation, which cannot meet the requirements of the electrolysis of the low...
