ALLOWABLE OFF-CENTRE LOAD FOR PRESSES ATS-0632-1998

1. Scope of applicationThis standard provides for general allowable off-center load for single-point and double-point pressing

machines that is used to establish calculation conditions at the design stage and operating conditions at the operating stage.

2. Basic view and expressions

2.1 Left and right direction on double-point presses (L-R of L-R 2-point presses and F-B and L-R of 4-point (F-B.L- R2×2)).

1) Limitations in terms of strength at either point Regardless of the presence of an overload safety device, allowable off-center load has to be set to such a value as to provide an off-center load of 1.0 P0 (1/2 P0 for each point-load)at the press center and provide an off-center load of 0.4 P0 at either point in terms of downward vertical.

Pa . (L/2+x )=L .P ' (1)

Now, P’ is given by the expression:

P '=Po /2−Pox /5L (2)

From expressions (1) and (2)

Pa=Po .(5 L−2 X )/5(L+2 X ) (3)

Where Po : Pressing Capacity (tf)Pa : Allowance off-center load (tf)P’ : Critical load (tf)A : Dimension of slide (tf)L : point-point distance (mm)X : Eccentricity (mm)Ma : Allowable rotation moment (kgf.m)

2) Limitations in terms of slide inclination resulting from the load imbalance between both points. Rotating moment Ma developed when a load 1/C2 of pressing capacity is applied from the center of a machine to a point locating at 1/C1 of the lateral dimension of the slide is taken as an allowable rotating moment.

Ma=A/C1. Po/C2=A .Po/CA C1 ,C2: Constant numbers

CA: Constant numberAs a result, an allowable off-center load Pa at the position that is spaced x from the center is give by the expression:

Pa=A . Po/CA .x (4)Constant CA is determined by allowable rotating moment Ma developed when a machine shows a predetermined inclination that varies with models. The expression given above satisfies reference inclination and constant CA specified in 3.

ALLOWABLE OFF-CENTER LOAD FOR PRESSES

2.2 Off-center load in terms of F-B direction on 2-point presses and F-B and L-R directions on 1-point presses

Pa=Ma / x=B . Po/CB .x (5)Constant CB is determined not only by the strength of the slide guide but also by allowable rotating moment Ma developed when a machine shows a predetermined inclination that varies with models. The expression given above satisfies reference inclination and constant CB specified in 3.

Where Po : Pressing capacity (tf)Pa : Allowance off-center load (tf)B : Dimension of slide (mm) X : Eccentricity (mm)Ma : Allowable rotation moment (kgf.m)CB :: Constant

3. Reference values: A pressing machine shall satisfy reference inclination and constant given in Table 1 when it is applied with a

reference off-center load.Table 1 Reference inclination and constant under off-center load

Note) The Specified inclination value (Standard inclination value according to Table 1) is the value calculated with the formulae specified in JIS B 6402 using the specified direction L (length). Therefore, when the dimensions of F-B or L-R changes, the standard inclination value also changes. The constants CA and C B given above are determined based on the measurements obtained from the machines that have been put into service. This means the measurements on the respective machines can exceed the reference value when taking the measurement errors into account. Reference values of inclination are not certified values.

4. Allowable off-center load diagram:The diagram should be made out as an example given in appended figure 1 in accordance with the three

expressions given in 2. Fractional dimension range should be, in principle, A/3 for double-point side and B6 for single-point side. To indicate an allowable off-center load outside the points, establish a measurement that satisfies the reference value specified in 3. Constant CA and CB are determined based on measurements on each models. It is allowed, therefore, to use the measurements as reference in the case where the measurements are unquestionable in accordance with annex

A1. Scope of applicationThis annex provides for requirements for measuring of allowable off-center load.

A2. Measuring procedureAllowable off-center loads are measured separately in terms of lateral and longitudinal directions.

A.2.1 Double-point directions1) Place a jack at a predetermined position (0.25×slide dimension. If the predetermined position is out of the

point, place a jack just under the point).2) Set the balancer pressure to “reference balancer pressure + 1 kgf/cm2.”3) Install a dial gauge at a position defined by “Parallelism measuring method” in JIS B 6402 (Test methods and

inspection for mechanical presses) and set the dial gauge at 0 (zero).4) Gradually increasing the jack pressure, read and records the loads given in the table below and

corresponding inclinations indicated by dial gauge.

Load 0.05Po 0.1Po 0.15Po □Inclination □ □ □ Specified inclination according to

Table1

Remarks: Po: Pressing capacity □: Measurement

A.2.2 Single- point direction1) Place a jack at a predetermined position (0.1×slide dimension).2) Set the balancer pressure to “reference balancer pressure + 1 kgf/cm2.”3) Install a dial gauge at a position defined by “Parallelism measuring method” in JIS B 6402 and set the dial

gauge at 0 (zero).4) Gradually increasing the jack pressure, read and records the loads given in the table below and

corresponding inclinations indicated by dial gauge.

A.3 Off-center load diagramOff-center load diagram is made out based on loads calculated in 2

Namely:Ma (double-point direction) = 0.25A . W1

Ma (single-point direction) = 0.1A . W1

Where Ma : Allowable rotation moment (kgf.m) Po : Pressing capacity (tf)A : Dimension of slide (mm)W1 : Jack load (tf)The specified inclination value (Spandard inclination value according to Table 1) is the value calculated with the formula specified in JIS-B-6402 using the specified direction L (length). Therefore when the L dimensions of F- B or L- R changes, the standard inclination vale also changes.

AIDA Technical StandardATS-0632-1998 EXPLANATION

ALLOWABLE OFF-CENTER LOAD FOR PRESSEXPLANATION

1. Reason for revision

Conventional ATS-0632-90 provided for references commonly used for all models of presses since there had been no definite and uniform concept with respect to allowable off-center load. To establish one reference allowable off-center load that applies to diversified kinds of presses, it was inevitable to adopt an allowable off-center load that was favorable to the presses. This forced customers to select a new press of a larger capacity, when necessary, as compared with the one they had used before the establishment of the aforementioned reference value even if the customers wanted to machine same works. This was a significant inconvenience from the customers' point of view.

To improve the above-stated situation, the conventional ATS-0632-90 has been thoroughgoingly re-investigated to provide allowable off-center loads according to allowable off-center load diagrams for each model of presses that had been used before the conventional standard was set..

2. Major improvements in the revision

1) Influence of HOLP break is additionally taken into account in the load limitation expression in terms of point strength. The expression is derived for a press that has a point within a slide area on the assumption that HOLP break takes place at approximately 80 % of rated point capacity by downward vertical single-sided off-center load to the point.

2) With respect to the limitation in terms of the slide inclination of double-point presses, constant CA has been established based on measurements respectively for each model. (In the conventional standard, the limitation was uniformly specified to a load that was 20% of pressing capacity at a position corresponding to 1/4 of the slide dimension.) Refer to appended figure 2 and ATD (AIDA TECHNICAL DOCUMENT)-208-304 for the conventional standard, comparison among models and detailed data.

3) With respect to the longitudinal direction of double-point presses and single-point presses, constant CB has been established bases on measurements for each model. Refer to appended figure 3 and ATD(AIDA TECHNICAL DOCUMENT)-208-304 for comparison among models and detailed data.

4) Constants CA and CB are mean values of measurements. This means the inclination reference value relative to the allowable off-center load can be exceeded when taking variations and errors in measurements into account. The inclination reference value is not a certified value.

5) For the load outside the point, a measurement according to the inclination reference value is to be indicated if specifically required.

6) Conventionally, diagrams based of measurements were made out to show 70% of the measurements. In the revised standard, they are made out to show 100% of measurements.

3. Important points to be noted for the use of revised standard.

1) This standard determines reference values based on measurements. For diagrams that have been prepared based on measurements, updating is not necessary.

2) This standard allows anybody to calculate a general allowable off-center load. However, if he/she wants to present the calculated allowable off-center load outside the company, the value has to be approved in prior by a section chief in charge of design of the model in concern. (Because, for some models, the allowable off-center load is indicated using measurements.)

3) This standard defines allowable off-center loads based on measurements of the existing models as of May, 1994. Inclination relative to the off-center load will change if structure or rigidity of presses changes. It is therefore necessary to utilize the standard while fully understanding that any change in structure of a commodity at the time of re-investigation will require re-design of the commodity to achieve an inclination that falls within the reference given in the standard or re-investigation of the standard itself.

4) For models of which constants are not defined in this standard at the present, constants will be additionally introduced based on measurements.
