Large-scale press processing system for transmission oil seal processing

Abstract

The invention discloses a large punching machining system for gearbox oil seal machining and belongs to the technical field of punching machining equipment. According to the key points of the technical scheme, a strip material uncoiling unit comprises a base, a rotating table, material coil fixing devices, a material guiding frame, a material coil close-abutting device and a material coil compressing device, wherein the material coil fixing devices are distributed on the two opposite side faces of the rotating table in the mode of being in central symmetry around the rotating axis of the rotating table, the material guiding frame is slidably arranged on the bottom face of one side of the base, the material coil close-abutting device is arranged on the material guiding frame and used for applying axial pressure to the end face, away from the rotating table, of a material coil during uncoiling, and the material coil compressing device is arranged at the top of the material guiding frameand used for applying radial pressure to the material coil during uncoiling. When uncoiled, the material coil can be pre-fixed at the material coil fixing device on the other side of the rotating table, the material coil is rapidly replaced through working of the rotating table, thus the material coil replacing efficiency is greatly improved, and the large punching machining system can adapt to efficient punching machining of a gearbox oil seal.

Description

Technical field [0001] The invention relates to the technical field of stamping equipment, and more specifically, it relates to a large-scale stamping processing system for gearbox oil seal processing. Background technique [0002] The oil seal is a mechanical element used to seal the oil. It isolates the parts that need to be lubricated in the transmission parts from the output parts, so that the lubricating oil will not leak. The special oil seals in automobile gearboxes in the prior art are generally composed of an oil seal skeleton and rubber. The traditional oil seal skeleton molding process is integrated by injection molding. This method cannot form continuous production, and the oil seal skeleton processing can only be done one by one, or It uses multiple injection molding equipment to process at the same time, not only the production efficiency is low, but also the production cost is relatively high. Therefore, the metal coil is often used as the raw material and the cont...

Problems solved by technology

[0004] However, its uncoiling device can usually only be used for uncoiling one coil at a time. When a coil is used up, it often needs to be temporarily shut down to replace the coil, which increases the time for changing and loading materials and limits the processing efficiency. further improvement
