Multi-station automatic feeding method and device

Abstract

The invention relates to a multi-station automatic feeding method and device. The feeding device is characterized by comprising an execution mechanism, a guiding mechanism, a driving device, a sensing limiting device and a control system, wherein the execution mechanism, the guiding mechanism, the driving device and the sensing limiting device are arranged on a frame; the execution mechanism comprises two walking beams which are arranged in parallel; a plurality of pairs of clamping devices are alternately arranged on the two walking beams; the guiding mechanism comprises feeding guide rails and feeding guide grooves, which are respectively arranged at two ends of the walking beams; a clamping guide groove which slides along one clamping guiderail is vertically fixedly arranged in the middle of each feeding guide groove; two ends of the clamping guide rails are respectively fixedly arranged on lifting guide grooves which slide along lifting guide rails; the bottom ends of the two lifting guide rails are respectively fixedly arranged on the frame; the driving device comprises a feeding driving device, a clamping driving device and a lifting driving device; the sensing limiting device comprises a feeding sensing limiting device, a clamping sensing limiting device and a lifting sensing limiting device; and the output end of the control system is connected with the sensing limiting device while the output end is connected with the driving device.

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 positi
