Abstract
The utility model discloses an adopt load cell's ultralow fast hydraulic press, including controlling means, frame, main motor, main oil pump, rack -mounted master cylinder, the work of main motor drive main oil pump, the work of main oil pump drive master cylinder, the output of master cylinder is provided with a load cell, load cell and controlling means electric connection. The beneficial effects of the utility model are that: adopt above -mentioned structure the utility model discloses an it detects to set up the direct pressure to master cylinder output of load cell at the output of master cylinder to with the data feedback that gathers to the controlling means in, take directly to gather the mode of delivery pressure and then can increase substantially the utility model discloses a control accuracy.
Description
Technical field
The utility model relates to a kind of Ultra-Low Speed hydraulic press adopting load sensor.
Background technology
Hydraulic press is a kind of is working media with liquid, is used for transferring energy to realize the machine of certain technique.Be usually used in the processing of industrial five metals, plate elongation moulding, stamping-out, the compressing and professional equipment that coordinates all kinds of mould and be widely used.The equipment of hydraulic forging press is one of mark of the national machine-building level of measurement one and ability.Hydraulic press, as a class common equipment, has very important effect in national product.
The pressure data of what existing hydraulic press relied on when controlling in real time is hydraulic oil in master cylinder, then by calculating the output pressure data converting master cylinder to, but there is certain deviation with actual output pressure data in the output pressure data that this converts, accurate, and then can affect hydraulic press is accurately controlled.
Utility model content
In order to solve the problem, the utility model provides a kind of Ultra-Low Speed hydraulic press adopting load sensor.
The utility model solves the technical scheme that its technical problem adopts:
A kind of Ultra-Low Speed hydraulic press adopting load sensor, comprise control device, frame, mair motor, main oil pump, rack-mounted master cylinder, mair motor drives main oil pump work, main oil pump drives master cylinder work, the output of described master cylinder is provided with a load sensor, and load sensor and control device are electrically connected.
The utility model also comprises the low speed pressurization pressurizer acted on master cylinder.
Described low speed pressurization pressurizer comprises servomotor, auxiliary oil pump, proportioning valve assembly, described driven by servomotor auxiliary oil pump work, auxiliary oil pump output is communicated with master cylinder by the first oil pipe, proportioning valve assembly is arranged on this first oil pipe, first oil pipe is also provided with check valve, and servomotor and control device are electrically connected.
Described proportioning valve assembly comprises pressure proportioning valve and flow proportion valve.
The beneficial effects of the utility model are: adopt the utility model of said structure directly to detect the pressure that master cylinder exports by arranging load sensor at the output of master cylinder, and by the data feedback that gathers in control device, take directly to gather the mode of output pressure and then control accuracy of the present utility model can be increased substantially.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is operation principle schematic diagram of the present utility model.
Detailed description of the invention
With reference to Fig. 1 ~ Fig. 2, the utility model is a kind of Ultra-Low Speed hydraulic press adopting load sensor 6, comprise control device 1, frame 2, mair motor 3, main oil pump 4, the master cylinder 5 be arranged in frame 2, mair motor 3 drives main oil pump 4 to work, main oil pump 4 drives master cylinder 5 to work, the output of master cylinder 5 is provided with a load sensor 6, and load sensor 6 and control device 1 are electrically connected.The utility model of said structure is adopted directly to detect the pressure that master cylinder 5 exports by arranging load sensor 6 at the output of master cylinder 5, and by the data feedback that gathers in control device 1, take directly to gather the mode of output pressure and then control accuracy of the present utility model can be increased substantially.
The utility model also comprises the low speed pressurization pressurizer acted on master cylinder 5.Low speed pressurization pressurizer comprises servomotor 7, auxiliary oil pump 8, proportioning valve assembly, servomotor 7 drives auxiliary oil pump 8 to work, auxiliary oil pump 8 output is communicated with master cylinder 5 by the first oil pipe 9, proportioning valve assembly is arranged on this first oil pipe 9, first oil pipe 9 is also provided with check valve 10, and servomotor and control device are electrically connected.Proportioning valve assembly comprises pressure proportioning valve 11 and flow proportion valve 12.Wherein auxiliary oil pump 8 adopts ultra low speed oil pump, and the arranging of proportioning valve assembly can be improved the degree of regulation of low speed pressurization pressurizer further and be extended adjustment process further.Low speed pressurization pressurizer quits work after main oil pump 4 drives master cylinder 5 to arrive rough location fast, now low speed pressurization pressurizer is started working, what maintain pressure in master cylinder 5 is positioned at setting pressure scope for a long time, and pressure limit can be accomplished comparatively accurate.
Above-described embodiment is preferred version of the present utility model, and the utility model also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the scope set by the application's claim.
