Description
Technical field
The utility model belongs to hydraulic press technical field, more specifically to a kind of large-tonnage long span multi-cylinder linkage
The compressing hydraulic press of automobile longitudinal girder.
Background technology
Hydraulic press is a kind of important molding equipment, produces highly pressurised liquid by motor driving hydraulic pump, passes through hydraulic cylinder
Produce linear motion be operated, because hydraulic press flexibility (adaptability) of operation is wide, thus be widely used in metal and it is nonmetallic into
Type processes occasion.
According to the number of column, hydraulic press can be divided into：Open side type (c-type), queen post, four-column type etc..Wherein, four post liquid
Press is more conventional, and it is a kind of static pressure using oil pump delivery hydraulic pressure oil to process metal, plastics, rubber, timber, powder
Deng the plant equipment of product.It is usually used in pressing process and block pressing forming process, such as：Forging and stamping, punching press, cold-extruded, alignment, bending,
Flange, process of sheet drawing, powder metallurgy, press fitting etc..Specifically include entablature, pedestal, the work between entablature and pedestal
Dynamic crossbeam and four root posts for connecting entablature and pedestal, four-column hydraulic press are treated rapidoprint by moved cross beam and pressed
System, in compacting, moved cross beam slides along four root posts.With the development of technology, for the workpiece using hydraulic press compacting
Also integration and maximization are increasingly tended to, such as the pressing operation of automobile longitudinal girder, this requires that hydraulic press has bigger work straight
Footpath and Geng Gao press power, existing four-column hydraulic press can not meet compacting demand.
The improvement that current hydraulic press is all carried out on the premise of four rod structure forms are not changed, such as Chinese Patent Application No.
For：201210038872.8 publication date is：The patent document on December 17th, 2014, a kind of four post hydraulic forging presses are disclosed,
By column, upper, middle and lower crossbeam, operating cylinder and backhaul oil cylinder are formed；Guide pillar structure is provided between middle cross beam and column,
It is characterized in：Guide pillar structure includes four groups of guidance sets being made up of guide plate and wedge, and wedge is pressed solid in by pressing plate
In crossbeam；Guide plate is provided with supporting plate close to the position of upper end, and adjusting pad is provided between supporting plate and pressing plate；Operating cylinder plunger
