With a wide range of USES, production efficiency higher characteristic, pressing machine can be widely used in cut off, punch, dropping material, bending, riveting and forming, etc. Craft. Through to the metal diecasting strong pressure on the metal plastic deformation and fracture occurred to processed into parts. Mechanical press work by motor through the triangle driving belt pulleys big (usually concurrently flywheel), after gear pair and clutch drive slidercrank mechanism, make the slider and the punch line to the downside. Mechanical press in fing press after pletion of work to the slider uplink, automatic clutch withdraws, and crank shaft automatic device connected, make the slider to stop in up stoper nearby. Crank press machine belongs to the mechanical transmission kind of press, is an important pressure processing equipment, it can carry out all the stamping, die fing process, directly produced semifinished products or product. Therefore, crank press in car, agricultural machinery, electronics, medical machine, national defense, aerospace and daily necessities, etc. industrial departments to a wide range of applications. With the development of industry, crank press the number and the variety of more and more, more and more high quality requirements, stressful, machinery manufacturing industry in his and other industrial production of the role of the press is getting more and more significant, improve mechanical automation degree, reduce labor intensity, and improve working conditions is the study of the main issue. The graduation design main analysis and design: J314000 KN press machine brakes braking scheme selection and parameter calculation and design。 Crank press brake the general structure of the design, draw the total assembly drawing。 And the design and drawing parts drawing. Key words: Crank press machine, Press machine brakes , Structure design， Wear coefficient, Floating set piece 青島理工大學畢業(yè)設(shè)計 目 錄 摘 要 ...............................................................................................................................I ABSTRACT ..................................................................................................................
