Composite slitting roller for transformer cooling fin

Abstract

The invention relates to a composite slitting roller for a transformer cooling fin. The composite slitting roller comprises a machine frame, a punching mechanism, a rolling shearing mechanism and a rolling shearing post-processing mechanism, wherein the punching mechanism, the rolling shearing mechanism and the rolling shearing post-processing mechanism are installed on the machine frame from front to back. The transformer cooling fin is subjected to punching, rolling shearing and side post-processing after rolling shearing on the left side and the right side of the transformer cooling fin sequentially through the punching mechanism, the rolling shearing mechanism and the rolling shearing post-processing mechanism, the punching mechanism is used for punching the left side and the right side of the transformer cooling fin, and the punching device is used for intermittently punching gaps on slitter edges, which can be cut off in a rolling mode, on the left side and the right side of the transformer cooling fin before rolling cutting, so that the slitter edges which are cut off in a rolling manner are in a segmented state. The invention has the following beneficial effects: the slitter edges with the punched notch become a segmented state after rolling shearing, so that the slitter edges are not wound on the machine, and the fault of shutdown is avoided.

Description

technical field [0001] The invention relates to a compound rolling shear machine for heat sinks of transformers. Background technique [0002] When the transformer is running, a large amount of heat will be generated due to the lack of eddy current in the transformer core and the load current flowing through the transformer winding. The heat must be dissipated in time, otherwise the transformer will be damaged. The main function of the transformer heat sink is to dissipate the heat generated by the transformer during operation to ensure the normal operation of the transformer. Therefore, the transformer heat sink is an important part of the transformer equipment. [0003] The transformer heat sink is composed of multiple heat sinks, and the heat sink is welded up and down by two layers of heat sinks. The welded heat sink needs to be cut off by rolling shears. [0004] At present, most of the rolling shearing machines used in the transformer heat sink production line on the...

Problems solved by technology

Due to the irregular movement of the cut waste edge, it is difficult to cut smoothly, often causing the waste edge to entangle the equipment, and the waste edge has to be removed manually, which affects the normal operation of the equipment, and there are hidden dangers in equipment and safety production, high labor intensity and low production efficiency.
