Description
Technical field
The invention belongs to press technical field, be specifically related to the hydraulic pump of a kind of forcing press.
Background technology
Forcing press is a kind of universal machine, its range of application widely, can be used for aborning cutting off, punching, blanking,
The processing technique such as bending, riveted and shaping, can be used for the maintenance of metal and orthopedic in life.The most small-sized
Hydraulic press is one of the most frequently used machine, and it is generally made up of parts such as hydraulic pump, frame and decompressors, wherein hydraulic pressure
Pump is to provide the vitals of power.At present, forcing press hydraulic pump common on market, generally there is volume big and cannot
Accurately control the drawback of pressure, the most in the course of the work, when the pressure of hydraulic pump is substantially not enough, it is impossible to complete workpiece
Assembling is with orthopedic, otherwise then easily causes the excessive damage to workpiece because pressure is excessive；It addition, used on existing hydraulic pump
Oil return valve be generally common handle arrangement, the press mechanism of usual hydraulic pump reset time need to open oil return valve, make down
Hydraulic oil in press mechanism passes back in hydraulic pump, but when quickly regulation oil return valve, the handle of oil return valve is because excessively rotating
And cause the phenomenon that screw rod comes off and happen occasionally, not only have impact on the speed of oil return valve regulation, and cause hydraulic fluid leak, make liquid
There is potential safety hazard in press pump.Thus industry is needed a kind of working stability badly, can quickly be regulated pressure and use the hydraulic pump of safety.
In view of above-mentioned prior art, it is necessary to the hydraulic pump structure of existing forcing press is reasonably improved.To this end, this
Applicant has made actively and effectively to explore, and finally defines technical scheme described below.
Summary of the invention
