Main transmission structure of double-acting high-speed precision punching machine

Abstract

The invention relates to the technical field of double-acting punching machines, in particular to a double-acting high-speed precision punching machine main transmission structure which comprises a crankshaft (1), large gears (2), small gears (4), a transmission shaft (6) and a flywheel clutch brake (7) assembly, the crankshaft (1) is of a four-crank-throw structure, and the large gears (2) are installed at the two ends of the crankshaft (1) respectively; the pinions (4) are mounted at the two ends of the transmission shaft (6); the lower end of the small gear (4) is meshed with the upper end of the large gear (2); the flywheel clutch brake (7) assembly is arranged in the middle of the transmission shaft (6) and connected with the transmission shaft (6), through the scheme, the dynamic balance balancing problem of the double-acting high-speed precision punching machine is solved, dynamic balance of components is kept in the working process, the precision of the punching machine and a die is effectively improved, the service life of the punching machine and the die is effectively prolonged, and the service life of the punching machine and the die is prolonged. And the abrasion of the shaft sleeve is reduced.

Description

Technical field [0001] The present invention relates to the field of double-acting punch technology, and more particularly to a double-acting high-speed precision punched bed main transmission structure. Background technique [0002] In the punch industry, it is generally considered to be more than 400 row / minute punch as a high-speed punch. At present, the highest stamping speed can reach 4000 row / min, and the high-speed pressing machine for high-level or high slider stroke roses is easy. Generate large vibration and noise, greatly reduce punching machine and mold precision and life, plus the bushing wear. The main reason for causing the above problems lies in the high-speed operation of the punch, and the rotary components cause a periodic change inertial force due to the imbalance of mass distribution, these inertial power cannot obtain effective balance, in the punch operation, rotary components such as flying wheel, clutch, crankshaft Swing components such as connecting ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problem that the above-mentioned double-action high-speed punch cannot solve the influence of inertia during use, which leads to a decrease in the precision of the punch and grinding tools and affects the service life, it provides solutions that can solve the problem of parts affected by inertia when the parts are working, and maintain dynamic balance.
