Description

technical field [0001] The invention relates to a feeding method and a feeding device, in particular to an automatic feeding method and a feeding device for multi-station forming of a press. Background technique [0002] For forgings or stampings with complex shapes, it often needs to go through multiple processes to form. Using a multi-station mold to arrange multiple processes on a set of molds can avoid many problems caused by process dispersion and greatly improve production efficiency. Therefore, multi-station automatic forming is the trend of modern forging production. In the multi-station forming process, the workpiece must be continuously transferred from one station to the next according to the predetermined processing cycle. At present, the transfer of workpieces between stations is usually performed manually, and there are the following problems: 1) The efficiency is low, each station needs to be operated, and when there are many stations, the transfer time is re...

Problems solved by technology

At present, the transfer of workpieces between stations is usually performed manually, and there are the following problems: 1) The efficiency is low, each station needs to be operated, and when there are many stations, the transfer time is relatively long, which slows down the production rhythm and cannot fully utilize The advantages of station forming; 2) The rhythm of manual operation is unstable. For warm and hot forming, the temperature of the workpiece will change irregularly, which will affect the consistency of product size and performance; 3) The labor intensity of workers is high. For warm and hot forming, The ambient temperature is high, the operation is inconvenient, and the working conditions are harsh; 4) Workers may sometimes put their hands into the mold for operation, which may pose a safety hazard; 5) Manual operation may lead to inaccurate feeding positions, thereby affecting the quality of formed parts

[0003] In recent years, some domestic enterprises have begun to introduce multi-station automatic feeding manipulators or feeding robots. This type of equipment has a complex structure and high equipment cost, making it difficult to promote and use it in small and medium-sized enterprises.

The utility model patent (ZL200920060562) of Shu Tianxiong and Lu Xiangpeng, multi-station stamping and feeding manipulator, uses the suction cup installed on the moving cross arm to intermittently extend into the mold during the stamping action, sucking the workpiece and transferring the workpiece between stations , but this method is only suitable for absorbable disc or thin plate workpieces, and has certain requirements for the adsorption surface of the workpiece, and cannot be used for complex stamping parts, let alone forging production
