Definitions

  • This invention refers to a high precision press for stamping sheet metal fitted with a set of items representing major advantages in respect of the state of the art, including a single central hollow lower ram which prevents unbalances in the stamping operation, and enables the evacuation of scrap, upper and lower adapter plates, a lower bottoming die on the bed plate or bolster, upper and lower punch holder plates and an attached die on a die shoe plate.
  • the devices currently available on the market are used for manufacturing precision items which comply with most of the requirements made by the final user, but are nevertheless not free from certain technical problems during the manufacturing process.
  • US 4267753 discloses a set of apparatus for producing a stamped item from a strip, which comprises a lower stripper, driven by a set of spiral springs and a central spring for operating the upper stripper. This type of cutting is commercially known as GRIP FLOW®.
  • US 4905556 discloses a stamping press comprising upper and lower central hydraulic cylinders for operating the strippers, with the expulsion of the workpieces and the scrap or cuttings taking place together from the lower machine bed upwards. This also comprises a tightening ring for securing the material around the workpiece during the stamping operation. This cutting system is known as "fineblanking".
  • WO 01/00396 describes a device for cutting pieces from a sheet of material, which comprises a press and is provided with a set of hydraulic cylinders and at least one additional cylinder for compensation at the bottom.
  • US 6370931 describes a press practically identical to the one of US 4267753 , but in which the spiral springs have been replaced by hydraulic cylinders.
  • US 3,304,823 A discloses a hydraulic press comprising a frame with a stationary working table and a movable working table.
  • the movable working table is actuated by a hollow cylinder to move said movable working table from a lower position to an upper position and vice-versa.
  • the cylinder is part of a driving unit which further comprises a piston and a piston rod with an annular section.
  • V-ring tightening ring
  • the purpose of this tightening ring is to stick a V-shaped wedge into the material surrounding what will be the finished part in such a way that this locks the material prior to being “punched”. This minimises the deformations in the material surrounding the final part and thus minimises the deformations in the finished part itself. This is not however the case according to the invention, as will be described below.
  • This manufacturing system entails greater consumption of raw material that can in some cases reach a level 35% higher than would be desirable.
  • the upper hydraulic cushion consists of at least two cylinders. This cushion is not steered by any guide element which guarantees its perfectly vertical and synchronic movement. For this reason there is an unbalance problem which affects the position and movement of the upper stripper, either due to a fault in one of these or simply to internal friction or pressure differences. This has a direct effect on the position of stripper pins, both at the time of extension, for which reason this directly affects the cushion bottoming die, the stripper pins and the upper stripper, and can damage this in its guide zone due to the axial strains caused by the unbalancing as well as the punches for internal openings in the part, usually known as "piercing punches".
  • the "axial locking" effect may result in the breakage of the cushion bottoming die, as well as the stripper pins, upper stripper, piercing punch or the actual cutting die itself, affecting the tooling or the quality of the part.
  • the upper cushion bottoming die is thin and not guided. For this reason there are cases of this being jammed in both the compression and the extension cycle, directly affecting the tool and making this break, as well as affecting the quality of the part.
  • the upper hydraulic cushion is inserted in a cavity and opposite this is its bottoming die, and in contact with this is the upper plate of the die shoe commonly known as "Die-set".
  • Die-set The GRIP FLOW® design places the cavity of the upper cushion just above the point where all the cutting pressure, or tonnage necessary for this, is exerted. This means that at the time when the part is cut the upper plate of the die-set is not supported on its uppermost face, that is, on the face where it is in contact with the bottoming die of the upper cushion. This entails that at the time of maximum effort, that is, at the point of cutting, the bottoming die is in a withdrawn position through the action of the upper stripper pins.
  • the upper plate of the die-set is located just in the area of contact with the bottoming die in the "air", with nothing to overlap the upper plate of the "die-set” or withstand the stress to which this is being subjected at the time of cutting this, and thus preventing its deformation.
  • the result of this lack of support or overlapping is the permanent deformation of this plate in the contact area of the bottoming die.
  • This has a direct influence on the quality of the part and life of the tooling, since the effect following this permanent deformation is that the other plates lose their flatness and thus their verticality and alignment. This means that the upper tooling "bites" into the lower tooling, gradually deteriorating the tooling with each new cycle that is run.
  • the die-cutter extends along the whole useful surface of the tooling. This is formed of a plate of the same size as the punch holder plate or the bottoming die plate of the tooling.
  • the die consists of a plate which performs the cutting action and a plate that supports this and guides the part after cutting its perimeter.
  • the lower ejection plate passes on the movement driven by the press carriage and due to the action of the stripper pins not being “guided” by any item guaranteeing the accuracy of its movement or its verticality, resulting in jams and bites in the punch.
  • the lower cushion is made up of at least two hydraulic cylinders. This cushion is not steered by any guiding item guaranteeing its perfectly vertical and synchronic movement. For this reason there is an unbalancing problem affecting the position and movement of the lower stripper pins and thus of the lower stripper in respect of the punch, so that the stripper can bite the punch in its upward expulsion movement, damaging this punch.
  • the punch is located on a lower plate of the die shoe; this plate is made of soft material, i.e. not hardened or hardened, and the punch will thus "stick into” this plate through the effect of the cutting pressure.
  • the punch is secured at the bottom of the tooling to prevent this from being pulled off at the time of ejection.
  • the punch having a flange facilitating securing this, there is a problem of securing this punch for parts that have little wall between the outside of the part and the inner cutaway, not having sufficient surface area to house any screws of sufficient size to support the traction stress of stripping the scrap or the remains of the outside strip of the punch, for which reason making this without the flange is not feasible, and its manufacturing is thus more expensive.
  • the lower part of the tool consists of a punch, a lower stripper, stripper pins and a lower die shoe or " die-set". This assembly rests on a plate which corresponds to the press bed, and this bed has a through-bore of considerable size to allow the scrap or cuttings through. There is thus the deformation problem mentioned above.
  • the plate rests on the die shoe, but there is no support in the cutaway area of the plate and the die shoe thus deforms through the effect of the cutting pressure and the tonnage exerted just in this area stemming from the stress on the punch, this plate being permanently deformed in this area; this affects the support of the punch, which loses alignment and verticality, causing the consequent "bite" on the die in the successive cycles due to the extremely limited tolerances between punch and die, and permanently damaging the tooling.
  • Precision stamping requires the balancing of both the upper and lower parts of the die, since when there is any unbalance two unwanted effects are produced: the first effect is the loss of accuracy in stamping the parts and the second effect is the greater wear of the dies, and thus an increase in the production cost and reduction in productivity.
  • This invention refers to a stamping press which solves all the problems mentioned above, enabling high accuracy and durability of the dies, and safety in removing the scrap, ensuring greater stability in making parts.
  • the press according to the invention comprises:
  • the machine bed has a housing for a lower adapter plate. At the bottom it also has a support or housing for a lower bottoming die apart from a set of through-bores for allowing stripper pins through.
  • the lower adapter plate also has a set of through-bores for allowing the stripper pins through, as well as holes for allowing the scrap or cuttings out. This lower adapter plate prevents the deformation of the lower die shoe plate.
  • This adapter plate will normally be made of steel.
  • the lower bottoming die is located at the bottom of the machine bed and also has through-bores for allowing through the stripper pins and for letting out the scrap or cuttings, the latter being a single large hole.
  • Said lower bottoming die will be made of hardened steel.
  • Said lower bottoming die has the purpose of preventing any permanent deformations on the lower part of the machine bed through impacts on the lower cushion in each expulsion cycle of the stamped parts. If said deformations were to arise through continuing use it is possible to replace said lower bottoming die, without needing to replace the bed.
  • the lower cushion is made up of a single central and hollow hydraulic cylinder, with an annular section.
  • the central bore of said lower cushion enables the expulsion of scrap or cuttings down through this without the decompensation or unbalance existing in devices with lower cushions made up of multiple cylinders.
  • the hydraulic cylinder is dual action, meaning that the movements and accelerations can be controlled, this being particularly advantageous for reducing the impact on the lower bottoming die of the bed.
  • the hydraulic cylinder is provided with a position-detecting device, such as an encoder.
  • the lower part of the die-cutting set is made up of a lower die-cutting set plate, a lower bottoming die of the die-cutter, a lower punch holder plate and possible a punch press plate, a punch and a lower stripper.
  • the punch holder plate is used for positioning the punch. In some cases the punch simultaneously performs the functions of the die. If the punch is not of the appropriate size to be held at the bottom with screw fittings, then an additional plate known as a punch press can be used. This comprises means for holding the punch by locking this, said holding means being made up of one or more parts.
  • This lower punch holder plate as well as the punch press plate will where applicable be located on a lower bottoming die of the die-cutter.
  • the lower part of the die-cutting set comprises a lower stripper.
  • Said lower stripper is provided with stripper pins for driving the expulsion movement, and guide columns which slide along guide bushes, guaranteeing perfect balance and high accuracy in the vertical movement of the lower stripper.
  • the upper cushion comprises a base plate on which there is a single dual action hydraulic cylinder which has a hardened bottoming die fitted at the bottom to prevent the deformation of this hydraulic cylinder through the effect of the stress of the transmission pins of the carriage adapter plate.
  • the hydraulic cylinder can be dual action, so that the movements and accelerations can be controlled.
  • the hydraulic cylinder is also provided with a device for position detection, such as an encoder.
  • the base plate comprises a housing for a plate for adaptation to the carriage.
  • This plate comprises through-bores for housing transmission pins, which are known as transmission pins for the plate for adaptation to the carriage.
  • This plate for adaptation to the carriage can be secured by screws or by a fast-release device.
  • Both the base plate and the plate for adaptation to the carriage can be fixed to an upper die-cutter holder plate.
  • an upper bottoming die for the die-cutter Fitted to this upper die-cutter plate is an upper bottoming die for the die-cutter, an upper punch holder plate, an upper guide plate and an upper die shoe plate. All these plates are made of hardened steel.
  • an upper die Secured to the upper die shoe plate there is an upper die. On the interior, in the die and the upper guide plate there is an upper stripper which slides through these parts. On the upper punch holder plate one or more piercing punches are fitted, through which the upper stripper slides. This stripper extends by means of transmission pins of the upper stripper which cross the set of plates forming the upper part of the die set and which rest on the transmission pins of the plate for adaptation to the carriage.
  • the expulsion of the die-cut part is performed through the action of the hydraulic cylinder of the upper cushion, through the upper bottoming die and the transmission pins of the plate for adaptation to the carriage and of the transmission pins of the upper stripper, which act directly on the stripper.
  • Both the bottom and top part of the die-cutting assembly are fitted on pins to guarantee their respective alignment.
  • a stamping press for a laminated metal material (28), such as a strip comprising:
  • the bottom part of the die-cutting assembly is made up of:
  • the top part of the die-cutting assembly is in turn made up of:
  • the press according to the invention comprises a lower adapter plate (18), placed in a housing made in the machine bed (17), said lower adapter plate (18) being provided with through holes for removing the scrap or cuttings, as well as for the lower stripper transmission pins (30) to go through.
  • Said lower adapter plate (18) is used to prevent the temporary or permanent deformation of the lower die-cutter holder plate (16), as well as the set of plates that are fitted on this (lower bottoming die (14), lower punch holder plate (31), punch press plate (32)), also preventing the misalignment or loss of verticality of the punch (15).
  • the stamping press of the invention also comprises a machine bed bottoming die (19), set at the bottom part of the machine bed.
  • This machine bed bottoming die (19) prevents the deformation of the bottom part of the machine bed through being pressed by the bottoming die of the lower cushion (33) in each cycle.
  • the lower cushion bottoming die (33) is fitted integral to the top part of the hydraulic cylinder (34) with an annular section.
  • the press carriage (21) comprises a base plate of the upper cushion (3) provided with an upper cushion.
  • the upper cushion comprises:
  • the hydraulic cylinder of the upper cushion (23) has the function of pushing the transmission pins of the plate for adaptation to the carriage (24) and the transmission pins of the upper stripper (26). Said upper cushion hydraulic cylinder (23) is driven by pressure lines (22, 42), which respectively have a pushing and braking effect.
  • the upper die shoe plate (11) houses the die plate (12), which means that a more expensive and stronger material can be used for the die, and in the event of breakage only the spoiled part can be replaced; in the case of multiple cavities (for multiple upper dies), only the affected part and not the entire dies can be replaced, significantly reducing the operating and maintenance costs.
  • the lower punch holder plate (31) can comprise different cavities in which different punches (15) are housed, in agreement with the upper dies or cavities.
  • the top part of the die-cutting assembly normally also incorporates one or more piercing punches (25); it is nevertheless possible for said piercing punches (25) not to be present when their use is not necessary for making the required part.
  • both the upper cushion hydraulic cylinder (23) and the hollow hydraulic cylinder for the lower cushion (34), comprise internal guides for proper guidance of the movement of the corresponding plungers as well as external scrapers for removing dirt.
  • the punch (15) can be secured directly to the lower die-cutter holder plate (16), for example by means of screws crossing the lower bottoming die of the die-cutter(14).
  • This solution can be seen in the diagram in Figure 4 .
  • the fixing device such as a securing part (323) fitted with a variable shaped flange (322) or with a housing for a ring (321), the punch (15) comprising a recess for partly housing said ring (321), with the securing piece (323) being the one that is secured to the lower die-cutter holder plate (16) or to the lower bottoming die of the die-cutter (14) by means of screws.
