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

A kind of unbalance loading detection method of multiple position press

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 (upper downstream side) transfer press Machine, the situation are particularly evident.It is limited by mold installation or in order to easy to operate, mold installation site is often subjected to offset tune Whole, this makes sliding block generate eccentric load.Eccentric load can cause biggish pressure to slide block guide passage, for a long time in this state Production can seriously affect guide passage precision.But traditional press machine does not have an individual unbalanced load protection device, it is only inclined when one side When carrying single-point nominal capacity of the power greater than press machine setting, overload device can just be triggered to protect press machine.And from torque meter From the point of view of calculating, as long as the stress point of mold and the point of application of press machine are offset, in order to guarantee the kinematic accuracy and guide passage zero of sliding block Part is not damaged, and the actual loading of mold increases with the offset of stress point position, it is desirable that its blanking pressure will be increasingly less than The nominal capacity of press machine.But also the unbalance loading of multiple position press can not be detected in advance at present, lead to multistation pressure There is bring security risk due to unbalance loading in power machine.

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), pre-enter the unbalance loading power curve of multiple position press itself in unbalance loading enquiry module, unbalance loading power curve with The eccentric position of mold is 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, and are sent to Unbalance loading computing module；

(3), received data are overlapped comprehensive operation by unbalance loading computing module, obtain all molds total stamping press and Total eccentric position is 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 power curve do Compare, if coordinate points, in unbalance loading power curve, the unbalance loading of press machine meets the design requirement of multiple position press, shows mould Block, which is shown, can normally produce signal；If coordinate points, outside unbalance loading power curve, the unbalance loading of press machine exceeds multiple position press Design requirement, 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.

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 power curve are pre-entered in unbalance loading enquiry module 3 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 are sent To unbalance loading computing module 2；

(3), received data are overlapped comprehensive operation by unbalance loading computing module 2, obtain total stamping press of all molds With total eccentric position and be 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 power curve do Compare, if coordinate points, in unbalance loading power curve, the unbalance loading of press machine meets the design requirement of multiple position press, shows mould The display of block 4 can normally produce signal；If coordinate points, outside unbalance loading power curve, the unbalance loading of press machine exceeds multiple position press Design requirement, alarm module 5 issue warning reminding.
