Description
Technical field
The utility model relates to the special-shaped connecting rod toggle link transmission mechanism of a kind of forcing press, particularly a kind of forcing press.
Background technology
The forcing press of traditional common toggle link transmission adopts straight line connecting rod toggle link structure, as accompanying drawing 1-accompanying drawing 2, the slider displacement of this forcing press is near bottom dead centre the time, almost motionless, the stop phenomenon is arranged, the reinforcement coefficient ratio of straight line connecting rod toggle link structure is less, and structure is comparatively complicated, and processing request is than higher, assembly difficulty is bigger, under the situation of identical stroke, owing to adopt the halfliner structure, so its pivot angle is restricted and less, and, the fuselage of whole forcing press is than higher, and the front and back size is also bigger, and floor space is bigger.Among the figure, 1 is halfliner, and 2 is upper elbow lever, and 3 is plain connecting rod, and 4 is lower elbow lever, and 5 is upper pin, and 6 is lower bearing pin, and 7 is middle bearing pin.
Chinese patent literature CN 1616221A discloses the multi-bar mechanical press of a kind of employing six jointed gear units on May 18th, 2005, two groups being made up of connecting rod and slide block of connecting in the outside of one group of quadric chain of being made up of crank-rocker mechanism.The reinforcement coefficient of this multi-bar mechanical press is still smaller.
The utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, the complete machine height is low, volume is little, in light weight, floor space is few, the special-shaped connecting rod toggle link transmission mechanism of flexible operation, forcing press that cost of manufacture is low, to overcome weak point of the prior art.
Press the special-shaped connecting rod toggle link transmission mechanism of a kind of forcing press of this purpose design, comprise crank throw, and the lower elbow lever that joins with slide block, lower elbow lever and upper elbow lever join, it is characterized in that also comprising special-shaped connecting rod, the middle part and the crank throw of this abnormity connecting rod join, and an end and the upper elbow lever of special-shaped connecting rod join, and the other end and the lower elbow lever of special-shaped connecting rod join.
Described upper elbow lever joins by an end of full bearing shell and special-shaped connecting rod.
Described lower elbow lever joins by the other end of full bearing shell and special-shaped connecting rod.
The special-shaped connecting rod toggle link transmission mechanism of forcing press also comprises intermediate bar, and an end of intermediate bar and an end of special-shaped connecting rod join, and the other end of intermediate bar and the other end of special-shaped connecting rod join.
Also be provided with upper cylinder and unloading cylinder on the described slide block.
The utility model is after setting up special-shaped connecting rod, slider displacement and crank angle become one-to-one relationship, the reinforcement coefficient of whole multi-jointed gear unit is effectively strengthened, structure is simplified, processing request is low, assembling is also than being easier to, under the situation of identical stroke, owing to adopt full bearing shell, so pivot angle can be enough big, operation also relatively flexibly, the height of whole forcing press has obtained effectively reducing, the appearance and size of front and back has also obtained effectively reducing, and the gross weight of forcing press reduces, and cost of manufacture reduces.
The utlity model has simple and reasonable, the complete machine height is low, volume is little, in light weight, floor space is few, flexible operation, characteristics that cost of manufacture is low.
