Pressure machine driven by multi-connecting-rod mechanism

Abstract

The invention discloses a pressure machine driven by a multi-connecting-rod mechanism. The pressure machine comprises a box body, a mounting plate, the multi-connecting-rod mechanism, a stamping sliding block and a stamping sliding block rail. The mounting plate is vertically fixed in the box body. The multi-connecting-rod mechanism comprises a crankshaft, a first connecting rod, a driving slidingblock, a driving sliding block rail, a second connecting rod, a third connecting rod, a fourth connecting rod, a fifth connecting rod, a sixth connecting rod, a seventh connecting rod and an eighth connecting rod, wherein the crankshaft is arranged on the front side of the mounting plate. An output shaft of the crankshaft makes circular motion, the first connecting rod moves along with the outputshaft, the driving sliding block is driven to move up and down, the second connecting rod is driven to move and drives the third connecting rod and the fourth connecting rod to move, the fourth connecting rod drives the fifth connecting rod to rotate, the fifth connecting rod drives the sixth connecting rod to move, the sixth connecting rod drives the seventh connecting rod and the eighth connecting rod to move, the eighth connecting rod drives the stamping sliding block to move up and down, and the moving direction of the driving sliding block is opposite to the moving direction of the stamping sliding block. The pressure machine has the advantages of being long in time for staying on a workpiece, high in stability, low in noise and the like.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a press, in particular to a press driven by a multi-link mechanism. Background technique [0002] Forging production occupies an important position in industrial production and is widely used in automobiles, precision electronics and other fields. The forging process produces workpieces with good quality, light weight, high production efficiency and low production cost. Most of the high-speed presses use the crankshaft slider mechanism as the working mechanism, and some use the sinusoidal mechanism as the working device. It is generally used for stamping the stator and rotor of the micro-motor. The rated power of the micro-motor is less than 750mW. If you want to stamp the lead frame (integrated circuit lead frame and separate lead frame), there is a flattened plane inside, and a certain electroplating process is required in the follow-up, which requires a very high flatness. Stamping such...

Most of the high-speed presses use the crankshaft slider mechanism as the working mechanism, and some use the sinusoidal mechanism as the working device. It is generally used for stamping the stator and rotor of the micro-motor. The rated power of the micro-motor is less than 750mW. If you want to stamp the lead frame (integrated circuit lead frame and separate lead frame), there is a flattened plane inside, and a certain electroplating process is required in the follow-up, which requires a very high flatness. Stamping such precision parts, crankshaft slider mechanism and sine mechanism and other stamping mechanisms are generally Unsatisfactory
