Description
Technical field
The present invention relates to technical field of hydraulic equipment, more particularly to a kind of hydraulic press.
Background technology
With the development of the society, the progress of technology, hydraulic press has consequence in production activity instantly.Hydraulic press
It is a kind of machinery that the products such as metal, plastics, rubber, timber, powder are processed using hydrostatic pressure.It is usually used in forging and stamping,
The compactings such as punching press, cold-extruded, alignment, bending, flange, process of sheet drawing, powder metallurgy, press fitting and forming technology.But traditional liquid
The liquid-filled tank of press major part hydraulic press is all independent placement on a hydraulic press, is then connected by oil pipe, subpress uses small
Fuel tank, big press just use big fuel tank, and liquid-filled tank majority is arranged on the top of hydraulic press, but the hydraulic press that some table tops are small
Liquid-filled tank is then suspended on outside machine, has both taken excessive space, also dangerous, if fixed loosely, is easy to fall
Situation.
In addition, existing hydraulic press can not adjust punching stroke mostly, and in practical operation, if punching stroke need to be adjusted,
Regulation process needs experienced staff to be operated, otherwise can because cushion block thickness or size it is incorrect, it is impossible to once
Regulation reaches range demands, but also need to take inside and outside red seat apart, then exchanges cushion block again and adjust again, and workload is big, work
Intensity is big, assembly and disassembly trouble, adjusts the bad quality and production efficiency that will directly affect product, and due to making, alignment error with
And the skew of sliding block, compressive deformation etc. in the course of work, necessarily parallel between main hydraulic cylinder and sill contact surface generally be present
Error is spent, the parallelism error causes main oil cylinder piston both ends unbalance stress, the unbalance loading of stroke oil cylinder, causes Cylinder Plunger and cylinder
The damage sealed between body, sealing effectiveness and seal life are reduced, so as to cause oil leak；Even result between Cylinder Plunger and cylinder body
The increase of fit clearance, cause the damage of equipment.
Such as Application No.：201621429574.1 Chinese patent discloses a kind of hydraulic press, including base (2), bottom
