Pressure transmission mechanism of intermediate connecting plate

Abstract

The invention relates to a connecting-rod pressure transmission mechanism of an intermediate connecting plate, belonging to the field of a connecting-rod transmission mechanism. The connecting-rod pressure transmission mechanism comprises two connecting rod mechanisms, a driving block, a sliding block and a machine frame, wherein the two connecting rod mechanisms are symmetrically arranged at the two sides of the axis of a diving rod in the center of the mechanism; each connecting rod mechanism comprises a frame connecting rod, a lower connecting rod and the intermediate connecting plate; the intermediate connecting plate is respectively connected with the driving block, the frame connecting rod and the lower connecting rod by a driving hinge, an upper hinge and a lower hinge; the other end of the lower connecting rod is connected with the sliding block by a sliding block hinge, and the other end of the frame connecting rod is connected with the machine frame by a machine frame hinge. Compared with a present symmetrical six-link mechanism, the connecting-rod pressure transmission mechanism of the intermediate connecting plate has the characteristics of high idle stroke speed and short single-trip time under the condition of equivalent force-increasing effect so as to well adapt to high-speed working, and has the advantages of relatively non-complex force bearing of a load-bearing shaft, hard breaking-off and small total height of the mechanism.

Description

technical field [0001] The invention belongs to a connecting rod transmission mechanism, in particular to a pressure transmission mechanism, which can be applied to presses, die-casting machines and injection molding machines in the field of metal and non-metal material forming. Background technique [0002] Symmetrical six-bar linkage press (product of Amino (Wuhan) High-Tech Co., Ltd.) is a newly popular plastic processing equipment. Compared with other traditional press mechanisms, such as the crank-connecting rod transmission press (see "<crank press", He Deyu, Mechanical Industry Press, 1987), the toggle transmission press (see "Mechanical Press Elbow Press") Optimum Design of Rod Transmission Mechanism", Zhang Yuantong, Zhu Denglin, "Machinery and Electronics", 2008(1), pp. 10-12), hydraulic transmission press (see "Design and Application of Hydraulic Press", Yu Xinlu, Machinery Industry Publishing House) and screw drive presses (see J58K series CNC electric screw ...

AI Technical Summary

Problems solved by technology

2. The force-increasing function of the symmetrical six-bar linkage mechanism is more obvious, which reduces the driving torque of the motor

However, the transmission mechanism of the symmetrical six-link press has the following problems: 1. The height of the frame is large, which occupies a high space and requires a tall delivery room, thus increasing the construction cost of the plant; 2. The speed of the empty stroke is slow, resulting in work efficiency 3. The effective boosting stroke is short, resulting in a short working range of the mechanism
