Abstract
The invention discloses a kind of unbalance loading detection methods of multiple position press, feature is the unbalance loading power curve that multiple position press itself is first pre-entered in unbalance loading enquiry module, station placement position and required stamping press corresponding to each mold are inputted in data input module again, and is sent to unbalance loading computing module；Received data are overlapped comprehensive operation by unbalance loading computing module, are obtained total stamping press of all molds and total eccentric position and are sent to unbalance loading enquiry module；Unbalance loading enquiry module compares the coordinate points where the total eccentric position received and total stamping press with unbalance loading power curve, if coordinate points, in unbalance loading power curve, the unbalance loading of press machine meets the design requirement of multiple position press；If coordinate points, outside unbalance loading power curve, the unbalance loading of press machine exceeds the design requirement of multiple position press；Advantage be this method can the unbalance loading situation in advance to multiple position press detect, to avoid slide block guide passage is impaired and existing security risk.
Description
Technical field
The present invention relates to the unbalance loading detection methods of multiple position press more particularly to a kind of multiple position press.
Background technique
For Large multi-station press since table top is larger, mold is relatively small, and certain parts in press machine are greatly without right
Claim, so that mold center can not be overlapped with the center of press ram, particularly with asymmetric multiple position press, the situation is special
It is unobvious.It is limited by mold installation or in order to easy to operate, mold installation site is often subjected to offset adjustment, this makes sliding block
Generate eccentric load.Eccentric load can cause biggish pressure to slide block guide passage, and long-term production can serious shadow in this state
Pilot road precision.But traditional press machine does not have individual unbalanced load protection device, only when the offset loading force on one side is greater than pressure
When the single-point nominal capacity of machine setting, overload device can just be triggered to protect press machine.And from the point of view of Calculating Torque during Rotary, as long as mould
The stress point of tool and the point of application of press machine are offset, in order to guarantee that kinematic accuracy and the guide passage part of sliding block are not damaged, mould
The actual loading of tool increases with the offset of stress point position, it is desirable that its blanking pressure will be increasingly less than the nominal energy of press machine
Power.But also the unbalance loading of multiple position press can not be detected in advance at present, cause multiple position press to exist because of unbalance loading
And bring security risk.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of unbalance loading situation progress that can in advance to multiple position press
Detection, to avoid the unbalance loading detection method of the multiple position press of security risk.
The technical scheme of the invention to solve the technical problem is: a kind of unbalance loading detection side of multiple position press
Method, including data input module, unbalance loading computing module, unbalance loading enquiry module, display module and alarm module, specific steps are as follows:
(1), the unbalance loading power curve of multiple position press itself is pre-entered in unbalance loading enquiry module, unbalance loading ability is bent
Line is using the eccentric position of mold as X-axis, the permitted total stamping press of press machine as Y-axis；
(2), station placement position and required stamping press corresponding to each mold are inputted in data input module, concurrently
Give unbalance loading computing module；
(3), received data are overlapped comprehensive operation by unbalance loading computing module, obtain total punching press of all molds
Power and total eccentric position are simultaneously sent to unbalance loading enquiry module；
(4), unbalance loading enquiry module by where the total eccentric position received and total stamping press coordinate points and unbalance loading ability it is bent
Line compares, if coordinate points, in unbalance loading power curve, the unbalance loading of press machine meets the design requirement of multiple position press, shows
Signal can normally be produced by showing that module is shown；If coordinate points, outside unbalance loading power curve, the unbalance loading of press machine exceeds multistation pressure
The design requirement of power machine, alarm module issue warning reminding.
Compared with prior art, it is an advantage of the invention that this method the unbalance loading situation to multiple position press can carry out in advance
Detection, if it is detected that mold unbalance loading exceed the design requirement of multiple position press, alarm can be issued in time, prompting operator is more
It is produced after mold exchange or replacement multiple position press, to avoid slide block guide passage is impaired and existing security risk, while
It ensure that the kinematic accuracy of sliding block.
Detailed description of the invention
Fig. 1 is principle schematic diagram of the invention；
Fig. 2 is flow diagram of the invention.
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
As shown, a kind of unbalance loading detection method of multiple position press, including data input module 1, unbalance loading calculate mould
Block 2, unbalance loading enquiry module 3, display module 4 and alarm module 5, specific steps are as follows:
(1), the unbalance loading power curve of multiple position press itself, unbalance loading ability are pre-entered in unbalance loading enquiry module 3
Curve is using the eccentric position of mold as X-axis, the permitted total stamping press of press machine as Y-axis；
(2), station placement position and required stamping press corresponding to each mold are inputted in data input module 1, and
It is sent to unbalance loading computing module 2；
(3), received data are overlapped comprehensive operation by unbalance loading computing module 2, obtain total punching of all molds
Pressure and total eccentric position are simultaneously sent to unbalance loading enquiry module 3；
(4), unbalance loading enquiry module 3 by where the total eccentric position received and total stamping press coordinate points and unbalance loading ability it is bent
Line compares, if coordinate points, in unbalance loading power curve, the unbalance loading of press machine meets the design requirement of multiple position press, shows
Show that the display of module 4 can normally produce signal；If coordinate points, outside unbalance loading power curve, the unbalance loading of press machine exceeds multistation pressure
The design requirement of power machine, alarm module 5 issue warning reminding.
Claims (1)
