Abstract

The invention discloses a transmission structure of a multi-connecting-rod mechanical press, which belongs to the field of presses. The transmission structure comprises an eccentric gear, an upper pull rod, an angular rocking rod, a lower pull rod, a crank connecting rod and a sliding block connecting rod, wherein one end of the upper pull rod and one end of the crank connecting rod are jointly hinged to the eccentric gear, the middle part of the angular rocking rod is hinged to a rack through a positioning shaft, the other end of the upper pull rod is hinged to the upper end of the angular rocking rod together through a first pin shaft, one end of the lower pull rod is hinged to the lower end of the angular rocking rod together through a second pin shaft, the other end of the lower pull rod, the other end of the crank connecting rod and the upper end of the sliding block connecting rod are hinged together through third pin shafts, the lower end of the sliding block connecting rod is hinged to a sliding block together, and the sliding block is arranged in a sliding sleeve. According to the transmission structure, all of the rods are reasonably matched in length and positions, so that the production efficiency is greatly improved, the service life of a mold is prolonged, and the transmission structure can be used in occasions with deep drawing heights.

Description

technical field [0001] The invention relates to a press, in particular to a transmission mechanism of the press. Background technique [0002] The motion curve of the conventional crank press is a typical sinusoidal curve, and the speed of the slider changes quickly above the bottom dead center, which is not conducive to the drawing and forming of the material. Generally, only shallow drawing of about 100mm can be completed, such as for deep drawing process , it is easy to crack the material, so it is mostly used in simple processes such as blanking, flanging, and shallow stretching. At present, the stroke speed of the hydraulic press for deep drawing process in the market is low, and the pressure stroke is large, but because the speed is constant during the whole movement process, it wastes more time and has low efficiency, and its efficiency also restricts the efficiency of the in-line press. , can no longer meet the requirements of modern stamping production rhythm. The...
