Description

A kind of pressurized construction of forcing press
Technical field
The utility model relates to forcing press, relates in particular to a kind of small-sized boost pressure machine.
Background technology
Current forcing press is mainly divided into common stamping machine and small-sized boost pressure machine, the former can reach ideal value by ordinary press stamping press, be applicable to the punching press of large mold sheet material, but overall volume is too huge, taken greatly site area, its cost performance of stamping-out for miniature workpiece is not high, for very inapplicable of a lot of small-sized and private enterprises; The latter is by utilizing the pressure of pressurized cylinder to increase pressure, and can make force value reach certain value, and its overall volume can reduce greatly, met the requirement of small portable, but for needing the product of particular pressure value, have certain pressure defect, when the special materials such as stamping-out stainless steel, this kind equipment can not mate completely especially.
If the small-sized special material part of stamping-out on common stamping machine, its cost is very high and productivity ratio is lower, and site requirements etc. has been limited to enterprise development greatly.In order to improve the defects such as the pressure of bulky and small-sized boost pressure machine of common stamping machine is inadequate, in industry, need at present a kind ofly possess enough stamping presses, and will meet appearance and size compactness, easy for installation, the novel press machine of the condition such as interchangeability is good.
Utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, compact appearance, the pressurized construction of the sufficient forcing press of stamping pressure.
The utility model is achieved through the following technical solutions:
A pressurized construction for forcing press, described forcing press comprises that order is arranged on punching press Power Component and the upper die component on vertical support frame from top to bottom,
Punching press Power Component is arranged on the top of support frame, and its take-off lever stretches in support frame straight down, and take-off lever can be done upper and lower ramming motion under punching press Power Component drives
