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

Embodiment

[0060] A large-scale stamping processing system for transmission oil seal processing, refer to figure 1 , which includes a strip unwinding unit, a strip straightening unit and a stamping forming unit arranged in sequence according to the running direction of the strip. When it is used for the stamping process of gearbox oil seal, the metal coil as raw material is fixed on the strip unwinding unit and slowly uncoiled; the uncoiled strip is straightened and flattened by the strip straightening unit and then sent to the stamping forming Unit; finally, the strip material completes the process steps of falling wafer, stretching, forming, shaping, punching, turning, punching and trimming at the stamping unit to obtain stamped parts.

[0061] refer to figure 1 and figure 2 , The strip unwinding unit includes a base 01, a rotary table 02 arranged above the base 01, a material guide frame 03 and a coil lifting device. A material roll fixing device for fixing the material roll 13 is...

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 punching equipment, more specifically, it relates to a large-scale punching processing system for gearbox oil seal processing. Background technique [0002] The oil seal is a mechanical component used to seal oil, which isolates the parts that need to be lubricated from the output parts in the transmission parts, so that the lubricating oil will not leak. The special oil seal in the automobile gearbox in the prior art is generally composed of an oil seal frame and rubber. The molding process of the traditional oil seal frame adopts injection molding. This method cannot form continuous production, and the oil seal frame can only be processed one by one, or It uses multiple injection molding equipment to process at the same time, not only the production efficiency is low, but the production cost is also high, so metal coils are often used as raw materials and processed by continuous stamping technology. ...
