Problems solved by technology

The former can only achieve a single adjustment of the output characteristics of the slider motion. After one adjustment, the output characteristics of the slider motion will also be fixed, which has limited improvement in the flexibility of equipment processing and process adaptability; the design of the latter has always been developed by foreign companies. Monopoly, the R & D and design of domestic servo forging equipment is limited by the cost of low-speed high-torque motors, and has not been effectively promoted

Abstract

The invention discloses a stroke-adjustable multi-rod boosting transmission mechanism and an adjustment method of the stroke-adjustable multi-rod boosting transmission mechanism. The stroke-adjustable multi-rod boosting transmission mechanism comprises a driving motor, a double-crank mechanism, a double-eccentric-wheel mechanism and a crank-link mechanism. The driving motor drives the double-crank mechanism through a gear reduction transmission mechanism, and then the double-eccentric-wheel mechanism fixedly connected with the double-crank mechanism is driven to rotate around a fixed shaft. A working sliding block is driven by a connecting rod hinged to an eccentric wheel mechanism body on the outer sides of double eccentric wheels to perform vertical reciprocating movement, and basic forging technological operation is completed; a movement transmitting rod of the double-crank mechanism is formed by jointly connecting two connecting rods through a thread connecting mechanism, the rod length can be adjusted within a proper range, a traditional crank mechanism is replaced by the double-eccentric-wheel mechanism, and the stroke of the sliding block can be adjusted by changing the relative positions of the eccentric wheels while the system bearing capacity is improved; the stroke-adjustable multi-rod boosting transmission mechanism and the adjustment method have the advantages that the structural layout is compact, the movement characteristics of the sliding block is adjustable, and the bearing capacity is high.

Description

technical field [0001] The invention relates to a multi-rod booster transmission mechanism with adjustable stroke and an adjustment method thereof, belonging to the technical field of mechanical manufacturing. technical background [0002] The traditional mechanical press mostly uses the crank-link mechanism as the main transmission mechanism, and the rotation of the motor is transmitted to the slider through the crank-link mechanism, so as to realize the transformation of the motion form and the transmission of energy. Once the dimensions of the crank and connecting rod are designed, the output characteristics of the slider movement are determined, which reduces the process adaptability of the equipment and limits the processing technology category of the process equipment. Therefore, the crank press is often not suitable for deep drawing, embossing and other process operations. [0003] In the field of forging equipment, changing the motion output characteristics of the s...
