A low-speed pressing and large-strength stroke mechanism

Abstract

A low-speed pressing and large-strength stroke mechanism, including a driving mechanism, a symmetrical pendulum input type boosting mechanism is arranged between the driving mechanism and a double toggle boosting mechanism, the guide rail of the driving mechanism and two symmetrically placed For the drive block, a double toggle booster mechanism is symmetrically arranged on the left, right, front and rear sides of the frame, and a symmetrical pendulum input type booster mechanism is also arranged between the drive structure and the double toggle booster mechanism. Cooperating, it has a large boosting effect in the working area of ​​the bottom dead center, which overcomes the shortcoming of the traditional boosting mechanism's short effective boosting stroke, and as the work progresses, the magnification becomes larger and larger, which effectively reduces the power source. Power, the structure of the present invention adopts a symmetrical form, which eliminates the partial load, has the advantages of rapid feed during no-load process, rapid return, high work efficiency, and can run at low speed to press parts, ensuring the quality and accuracy of parts forming, and has a wide range of applications, etc. advantage.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a low-speed pressing and large-strength stroke mechanism. Background technique [0002] In modern large-scale equipment, the actuator often needs to output a lot of force, but under the condition of a certain power source, the direct output is far from meeting the actual demand. , the initial small force is converted into a larger output force through the booster mechanism to meet the actual demand, which not only reduces the cost of the equipment, but also improves its flexibility, saves energy, and improves the competitiveness of the product. [0003] However, common booster mechanisms have disadvantages such as small initial boosting effect, short effective boosting stroke, inconspicuous boosting effect, large size of the overall mechanism, slow working speed, and low efficiency. Invention content: [0004] In order to overcome the disadvantages of the above-mentioned...
