Foreword This guide is not:
A collection of « design rules ». Exhaustive in propositions.
This guide is a reminder of a few basics and examples, and must be enriched with: The different user projects. All manufacturing sites by the intermediate of different DIVDs.
NOTE: Cutting for butt welding This guide can be used for tools for cutting blanks for butt welding, but in case of contradiction, use preferably guide GE24-050R.
1.1 Height of the cutting plane in respect of feed plane ! For specific cutting tooling, place the working parts on the level of the feed plane.
! For notching equipment fitted on a standard frame, place the notching cutting parts on the same level
as the shear blades. ! The height of the elevator table in the lower position must be recessed by 1 mm in respect of the
blades.
1.2 Specific and standard tool frames
1.2.1 Handling See standard EM24.02.031
1.2.2 Adjustment and safety ! Include 4 supporting ranges for safety jacks on all specific tools. ! Include 4 adjusting spacers (gap = 0.3) beside a rib.
1.2.3 Reaction All reactions must be cancelled. A reaction stop located at each angle of the lower and upper frames must be implanted with its friction plates without insert (steel on cupro). These stops are useless in the case of cutting in full panel or if compensation reactions are planned opposite notch(es) to be produced.
1.2.4 Pneumatic plate position The position of the air intake on the machines is variable, refer to the press technical sheets. In the foundries of the « PAL » frames, include a recess for fitting a 7- or 10-hole plate on the front and rear left to allow the fitting corresponding to the type of press. In foundries for 630-tonne PAL 166 ″ frames, the recess of the 10- or 11-hole plate is located on the right lateral side in the press axis, include front left backup.

1.7 Belt lifter The belt lifter is designed according to the cutting tooling, and must ensure the belt�s displacement above the working parts.
The belt lifter must not : Cause any scratches or marks on the blanks of the skin parts. Reduce the rate planned of the range.
1.8 Belt guide The belt is guided by moving rollers, fixed rollers or belt guides. The belt axis must be placed in the press and tool axis. Offcentring (exceptional) of the belt by ± 50 mm, as approved by the user plant.
1.9 Stripper Use in priority the strippers in polyurethane elastomere, several types can be used:
Flexible strippers with rectangular segments height 35 mm. Flexible strippers with rectangular segments height 65 mm. Cylindrical flexible strippers (PON�PON) height 65 mm fastened with elastic pins
For a straight or large radius cutting, use only flexible strippers with rectangular segments. In the case of complex shapes with small radius, use flexible strippers with segments combined with cylindrical flexible strippers. Notes: Upon fitting, elastic strippers must be supported against the blades and blade holders. The strippers must rest over their entire pressure surface.
1.9.1 Stripper for complex shape blank Use of a stripper in E295 steel, thickness 50 mm (Cast steel requires plant approval). The tool is usually made of several steel strippers beside cutting out and separation blades. They can be combined with strippers in polyurethane. If a stripper has a functional unbalance, compensators can be included and fastened on the lower frame. A 0.2 mm gap must be included between the compensators and the stripper. A protection cover in 2 mm panel must be fastened on the upper frame.
The parts of the presser not in contact with the blades must be cleared.
" Protection cover in S185 sheet # Die blades and punch

1.9.3 Coil for stripper weight < 400 kg See standard EM24.55.100
1.11 Belt guide «Particular cases » For parts requiring rigorous geometry, include a belt centring device (adjustable).
1.12 Evacuation of non recovered scrap Evacuation of notching and cutting out scrap must be ensured at each press stroke:
Plan broadly sized scrap passages. Slopes must be ≥ 30°. (or exceptionally 15° on rollers).
The gutters are in S185 panel, thickness 3 mm, and must support scrap up to the PMR edge. Jointed and folding gutters must be fitted if these protrude from the frame and are not protected
against shock. Scraps can be evacuated along natural slopes ≥ 30° (foundry).
Max dimension of cutting out scraps (Waste) on PAL 166 press �� See standard EM24.02.033
2.1 Conditions of evacuation of blanks and scraps The evacuation direction of the blanks and scrap must be defined according to the type of press. Beware front of press: see technical sheet EM24.03.200 • Reminder: no positive ejection.
2.1.1 Blank cut 1 stroke/1 blank Blank collection between post is performed by gravity, magnetic conveyor, or motorised roller ramp. Avoid separating the scrap and part at the same station (part remaining supported on blades).
2.1.2 Blanks cut 1 stroke 2 blanks The first blank (lateral exit) drops on the moving table and is ejected at bottom stroke by a ��kicker�� device installed on the lower part or for rates above 30 str/min, by motorised magnetic rollers. The second blank is evacuated between posts, by gravity, on motorised roller ramps (or brushes) or on the capacity magnetic belt. A moving table ensures passage of the belt between the shears at top of stroke. NOTE: lateral evacuation of the 1st blank is located to the right of the forward direction, regardless of the position of front of press. Example of blank evacuation
- evacuation of large size blanks (mark A). - evacuation of blanks with « step » below 800 mm (mark B) as accepted by plant. - evacuation of small size blanks (mark C) with plant acceptance.
Blanks centring A centring system must be included for simultaneous left and right blank cutting for panels lined on one side.
2.2 Frames See master drawing GE24-014R Plan: - 2 rolling paths under lower frames fitted without riser. (see Press T.S. and chapter 3).
- refitting of lower frame soles for tool pusher coupling. - properly spaced lower handling eyes for passage of slings. - bearing ranges beyond the implantations of blades on lower and upper frames. - 4 ranges for elastic spacers height 160. - 4 columns Ø 100 in lower part. - 4 bushes engaged without inserts H7/g6.
2.2.1 Tool weight In all cases, the weight of the tools must be below: - 20 tonnes for PAL�� presses in FLINS. -25 tonnes for PAL�� presses in other plants. Take into account the inter-plant backup plan.

2.4 Specific tooling Final cuttings must be banned. This tooling is fitted without riser to handle part and scrap evacuation (Priority solution HOF = 1180 ± 1)
2.4.1 Belt guiding Belt guiding is ensured by fixed rollers. If required, add fixed belt guides on the lower part of the tool. The belt axis must be placed in the axis of the press and tool, except exceptional case, the belt can be offset by ± 50 with approval from the user plant Distance between belt guide rollers = Belt width + tolerance + 1mm
2.4.2 Belt lifter It is made of a light and rigid structure, in mechanically welded profile (square tube). It is fitted with spring retaining screws in elastomere, for a stroke ≤ 20 mm and precompressed
assemblies with stroke > 20 mm, the moving frame will be folded by elastic compensators fitted on the upper part.
The belt lifter stroke is determined according to proper passage of the belt. It is fitted with cylindrical rollers ∅ 50 (Standard EM24.57.500) and deflector(s) in brass sheet
(blank for skin part) to ensure belt entrance and displacement. For other blanks, the deflector in steel panel thickness 3 mm is welded (or screwed) on the belt lifting structure.
No paint on metallic structure. Example, tool at bottom stroke:
Belt engaging To help engaging the belt in the tool, include a sufficiently large belt entrance deflector. The deflector is in steel sheet thickness 3 mm welded on the frame or in brass sheet screwed onto the frame. The belt touches the deflector during its introduction, but must not be in contact with it during belt advance (manufacturing).
2.5 Lateral evacuation moving frame ! The length of the frame is at least equal to the length of the blank to evacuate. ! The blank must not bend, it is supported by ball casings distributed over the entire surface of the
blank. ! It is actuated by 2 lifting systems (minimum). ! If the blank is not supported up to the press evacuation system, include a ramp fitted with rollers.

2.7 Standard frames with fixed shear These frames are fitted with a fixed shear, a belt support, and adjustable belt guides. HOF of the frame = 1180 ± 1 on PAC and PAL. 0 On the other hand, these frames are likely to be fitted with equipment with an HOF 460 -0,5 to perform cutting out, notches, etc. (with plant approval). See the reference numbers on the frames and equipment in paragraph 6.
2.8 Standard frames with moving shear These frames can be fitted with a moving shear with straight cut or a moving shear with cutting radius 2000 ; 5000 etc... 0 On the other hand, these frames are likely to be fitted with equipment with an HOF 460 -0,5 to perform cutting out, notches, etc. (with plant approval). The fitting of a moving shear with the equipment on the frames depends on belt laying. (See the reference numbers on the frames and equipment in paragraph 6).
2.9.1 Process of the study for tooling with equipment Starting with belt laying and characteristics of the shear holder, determine the location of the shears (plot the view at scale 1/10 in folio No.1 of the study). Place: 1) the shear as close as possible to the frame guides on the blank evacuation side.
2) the equipment as close as possible to the shear blade with a minimum number of steps between notchings and shear.
2.9.2 Tooling design (equipment) The frames are fitted with 4 handling pins. The yokes are machined in the plate according to possibilities:
- 4 safety jack ranges. - 4 storage spacers. - 4 adjustment spacers. - Include centrings and fasteners according to the standard frame used.
2.9.3 Stripper Identical to specific tooling.
2.9.4 Conveyor guiding Identical to specific tooling.
2.9.5 Conveyor lifter Identical to specific tooling. Include ramps with rollers ∅ 50 (standard EM24.57.500) to support the belt between the equipment and shear of the standard frame, and upstream the equipment.
Example of specific equipment fitted onto a standard frame with shear

2.10 Standard frame with 2 moving shears These frames are fitted with two straight cutting shears with independent adjustment (longitudinal and angular). The position of both shears on the frames changes according to the belt laying. The 1st blank is evacuated between the 2 shears by a moving system (table actuated by elevators, and possibly a palm button) and the 2nd blank after the exit shear on a train of brushes or rollers or directly with the evacuation belt. 0 On the other hand, these frames are likely to be fitted with equipment with HOF 460 -0,5 (See the reference numbers on the frames and equipment in paragraph 6).
2.11 Fitting schedule � Backup all plants All possibilities of fitting of the tooling must be studied in order to change press and plant allocation. Tooling of the PAC 108�� must be fitted on PAL 136��, 166��, include retractable belt stands on feed side. (See press technical sheets). The tooling of the PAC 136 �� must be fitted on PAL 166�� (See press technical sheets). Notes: - Fitting a PAC 108�� tool on PAL 166�� must be offcentred and close as possible to blank evacuations. - Beware front of press. The manufacturing sheet must indicate the backup presses and workshops. A fitting FOP must be established at each study of a PAC 108��.
2.12 Press not fitted with a magnetic belt a) For narrow blanks evacuated between posts, include in the tooling a motorised roller ramp allowing
blank advance up to the evacuation system. b) If the blank to evacuate does not reach the evacuation system: include a ramp fitted with rollers to
support the blank. c) The roller ramps must be jointed and folding when protruding the frames.

5.7 Stripper Belt extraction is ensured by a stripper plate actuated by equipment with retaining spring or flexible strippers. Stripper retaining (See standard EM24.55.100) Include a protection panel around the stripper and ensure proper balancing of the stripper.
5.8 Belt guiding See master drawing for progressive tool (GE24-014R)
5.9 Belt lifter Passage of the belt above the blades is ensured by a belt lifter plate actuated by springs or support pads. The belt must be supported over the entire length of the tooling.
5.10 Blank evacuation The blanks are supported by bars fastened between the cutting blade and the press evacuation system (belt). The blanks are evacuated by magnetic rollers (∅ 50) driven by a pneumatic motor.
