Problems solved by technology

[0002] In the existing technology, parts with complex and precise parts processing requirements such as precision pressing, embossing, lettering, etc. are generally produced on multiple hydraulic presses. The hydraulic presses are low in efficiency, easy to leak oil and occupy a large area of ​​use, etc. Constrained by many factors
The production efficiency of the ordinary press is higher than that of the hydraulic press, but the upper and lower abrasive tools must be pressed during cold extrusion and embossing, but this makes the crankshaft easy to break

Abstract

The invention relates to a transmission device of a press. The transmission device comprises a gear wheel, a connecting rod I, a rocker, a crankshaft, a key, a connecting rod II, upper toggle rods, lower toggle rods, ball screws and a slider body, wherein the gear wheel is connected with the connecting rod I and the rocker through hinge pins; the rocker is fixedly connected with the crankshaft through the key; the crankshaft is fixedly connected with the connecting rod II; the upper toggle rods are fixedly connected onto a press body and fixedly connected with the connecting rod II; the lower toggle rods are fixedly connected with the ball screws; the ball screws are fixedly connected onto the slider body. A slider can stay at about 50 degrees at a lower dead point through a unique operation curve of a multi-point toggle rod mechanism, the metal molding time is increased to the greatest extent, and plastic deformation of metal is better facilitated.

Description

technical field [0001] The invention relates to a transmission device, in particular to a transmission device of a press machine. Background technique [0002] In the existing technology, parts with complex and precise parts processing requirements such as precision pressing, embossing, lettering, etc. are generally produced on multiple hydraulic presses. The hydraulic presses are low in efficiency, easy to leak oil and occupy a large area of ​​use, etc. Constrained by many factors. The production efficiency of ordinary presses is higher than that of hydraulic presses, but the upper and lower abrasive tools must be pressed against during cold extrusion and embossing, but this makes the crankshaft easy to break. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a press transmission device that can maximize the metal forming time. [0004] In order to achieve the above object, the press...
