For this reason, the tool lower portion 300 of the instruments of inspection 100 is furnished with multiple workbench liner plug 390, and they axially movably can extend through the boring 311 in substrate 310.Workbench liner plug 390 with its bottom directly or where necessary also can indirectly at press bench interior support on drawing backing plate.By the decline of drawing backing plate or rising, workbench liner plug 390 is moved downward or upward.
When tool component 200 and 300 moves downward period (measuring in stroke) engagement at depression bar, in position that is that workbench liner plug 390 is in top usually or that roll away from, therefore be first that the 3rd plug 290 in upper tool part 200 contacts (side contacts) with the workbench liner plug 390 rolled away from tool lower portion 300, this such as simulates the process of placing clamping device.When depression bar moves downward further, the drawing backing plate in press bench is extruded downwards, wherein, is applied to the lower basal plate 220 of upper tool part 200 by pressure from drawing backing plate by plug 390 and 290.Can be detected by the measuring cell 230 (being between lower basal plate 220 and upper substrate 210) in upper tool part 200 and analyze and record in measuring technique by the pressure of drawing backing plate according to default generation at this.By that separate of measuring cell 230 or zonal analysis, also can detect and in measuring technique analyze and record local power poor.
The inclination of drawing backing plate in press bench will inevitably cause lower basal plate 220 to tilt relative to upper substrate 210 in upper tool part 200.This inclination can be detected by the tactile displacement measurement sensor 245 in upper tool part 200 and analyze and record in measuring technique, can infer performance or the speciality of drawing cushion facility thus equally.Measurement procedure in the measurement stroke started can carry out as previously mentioned.
The inclination of drawing backing plate in press bench also can be measured by measure-axis 325 as previously mentioned.
According to elaboration regulation before, when in measurement stroke, depression bar moves downward, first be that workbench liner plug 390 in tool lower portion 300 engages with the 3rd plug 290 in upper tool part 200 or contacts, gas spring 360 engages with 370 with the first and second plugs 260 or 270 in upper tool part or contacts afterwards.Simulate the process of placing clamping device in common deep-drawing technique thus.In order to simulate the shaping of other and/or cutting technique, workbench liner plug 390 also just can contact with the 3rd plug 290 after gas spring 360 with 370 engagements, and this can by the axial length of workbench liner plug 390 and/or by controlling position in press bench of drawing backing plate or motion regulates.If should when there is no drawing pad in forming press service test instrument 100, then can remove workbench liner plug 390.
By aforesaid measurement, measuring the performance of Check and Inspection instrument 100 in stroke (decline of depression bar and upper tool part fixed thereon, the stopping if desired in UT and lifting).Performance or the speciality of forming press to be checked can be determined thus.Therefore, to the performance of forming press to be checked or the detection of speciality or determine directly not carry out, but indirectly carried out by the instruments of inspection 100 be arranged in forming press.
Aforementioned measurement also can be carried out when opening instrument or promoting depression bar similarly.In addition, all aforementioned measurements need not be carried out in a measurement stroke.That is, when in forming press to be checked during service test instrument 100, need not function in all measuring techniques of application verification instrument 100 and possibility.Independent measurement function can be applied targetedly.This achieve and use neatly according to the instruments of inspection 100 of the present invention.
Static properties and the dynamic property of forming press can relatively comparatively fast and simply be determined or detect to the instruments of inspection 100, wherein, can produce for forcing press specific " fingerprint " the reaction of suffered load according to forming press.This can when new installation forming forcing press (examination when such as purchasing), in general measure time (continuously inspection pressure machine state and detected pressures machine wear phenomenon) and/or error correction on warehousing pressure machine (identifying forcing press fault earlier) time or carry out comparing measurements (such as comparative test forcing press and comparing and measuring in batches in press procedures) time to different stock's forcing press.
