    CLAMPING DEVICE FOR PNEUMATIC CLAMPS SUSCEPTIBLE TO BE COUPLED TO THE TRANSFER OF A STAMP PRESS
    The present invention relates to a clamping device for pneumatic clamps capable of being coupled to the mobile bar of the transfer of a printing press through at least one clamp holder profile of said device.
    10 Background of the invention
    At present, the clamping devices for pneumatic clamps in presses with stamping transfer are of the type comprising a plurality of clamp holder profiles provided with a plurality of clamping brackets of tubular support elements of the 15 pneumatic clamps that are distributed over a series of different consecutive stamping dies.
    The clamp-holder profiles of the existing clamping devices comprise longitudinal grooves provided for removably attaching the plurality of clamping brackets of the tubular support elements of the pneumatic clamps. These support brackets include a first type of support adapted to receive one end of one of said tubular elements and a second type of support provided with two semi-open rings to simultaneously receive the opposite end of said tubular element and the end of another parallel tubular element that occupies an extreme position. The respective pneumatic clamp is mounted on this last tubular element.
    25 The clamp-holder profiles are capable of being removably coupled to two bars belonging to the transfer of the press, capable of performing a reciprocating movement in the direction of advance of the sheets to be stamped, so that a group of clamps Associated with a pair of pin-holder profiles facing the same die, it is able to hold a sheet to be stamped, transfer it to the next die, and return to its respective die while stamping to repeat this process with the subsequent plates to be stamped or punching. Depending on the type of die or sheet to be stamped, the operators choose one type or another of pneumatic clamps for attaching to the transfer bar of the printing press. Once the stamping is finished, the clamping devices are decoupled from the transfer bar and transported to the warehouses.

    The manipulation of the existing clamping devices is expensive for the operators, since the weight of the set of clamp-holder profile, of the clamping supports, of the tubular elements, as well as of the clamps themselves, is high. This hinders, on the one hand, the manipulation by the operators and, on the other hand, has a negative impact on the productivity and reliability of the stamping process. Indeed, a high weight of the device directly affects a lower precision and speed of movement of the transfer bar to which the clamp-holder profiles are coupled with their respective clamping supports of the tubular elements, reducing the productivity of the press and increasing with it the economic cost of manufacturing the stamped sheet.
    Description of the invention
    The objective of the clamping device for pneumatic clamps of the present invention is to solve the drawbacks of the existing clamping devices, providing a lighter and easier to handle device that at the same time retains good mechanical strength and resistance properties. abrasion.
    According to this objective, according to a first aspect, the present invention provides a clamping device for pneumatic clamps attachable to the transfer of a stamping press through a clamp holder profile, comprising a plurality of clamping brackets of about tubular support elements of said clamps, said supports being susceptible to being coupled to said clamp holder profile, each of said clamping supports including a body adapted to receive at least one of said tubular elements and means to ensure at least one of said tubular elements in the body of said support bracket, and is characterized in that the base component of the body material of each of said support supports includes at least one techno-polymer.

    In addition, the techno-polymer material electrically insulates the support brackets, which is very useful if the working environment of the printing presses is taken into account. On the other hand, the techno-polymer material is very light without losing the mechanical resistance that is necessary to ensure the tubular elements that support the clamps optimally. The lower weight directly affects higher press productivity (faster travel speed and greater precision in the handling of the sheets to be stamped).
    In the present invention, techno-polymer means a polymeric or plastic material provided with a mechanical resistance, chemical resistance and heat resistance that makes it suitable for replacing a metal in the claimed application. In particular, techno-polymer means a polymeric material selected from a PA6 polyamide, a PA66 polyamide, a semi-aromatic polyamide or polyphthalamide (PPA) and a polyphenylene sulfide (PPS), or a mixture thereof.

    The body of the first set of support brackets 3a of the claimed device includes two body portions 12, 13 separated from each other so that they define a surface 14 for mutual tightening by means of fastener elements 15a that fit into holes in the body of support 3a. This surface 14 acts as a mechanical stop during tightening to avoid breakage or deformation in the techno-polymer material. The tubular support element 4a can be secured between the two body portions 12 and 13 so that its axis is arranged parallel to the support body 3a (see figures 7a, 7b) or, alternatively, can be secured so that its axis is arranged vertically
    with respect to the support body 3a (see figures 8a, 8b). In any case, the body of said

    brackets 3a is configured to be directly coupled in the longitudinal grooves 7 of said profile 2 clamp holders by means of fastener elements 15b.
    The body of the second set of support brackets 3b of the claimed device includes a pair of semi-open rings 16a, 16b adapted to receive simultaneously and respectively, the first tubular element 4a and the second end tubular element 4b associated with a clamp 1 pneumatics.

Optionally, one of said rings 16b can house inside a ball joint 18 configured to receive the end-of-end tubular support element 4b of the clamp 1.
    Figures 9a, 9b and 9c show a first embodiment of the second set of fastening brackets 3b in which the rings 16a, 16b of the support body 3b are arranged almost adjacently separated by a reinforcing wall 17.
    Figures 10a and 10b show another second embodiment of the second set of support brackets 3b in which the body of the support 3b defines a diagonal section of connection between the rings 16a, 16b. This section is designed to facilitate the position of the clamp 1 within the press transfer.
    Figures 11a, 11b and 11c show a third additional embodiment of the second set of fastening brackets 3b in which the rings 16a, 16b are rotatably mounted on the same conical axis of rotation 19. The ends of said conical axis 19 of rotation are configured to be able to adjust the fastener elements 15a intended for tightening the respective tubular elements 4a, 4b inside said rings 16, 16b.
    The support 3b with clamp 18 of Figures 11a, 11b and 11c allows the six degrees of freedom, that is to say three displacements, three turns and their orientation, necessary to place the clamp 1 at any point in the space. This is especially useful given the complexity of the sheet to be handled within the transfer bar of the press in a stamping process.
    As mentioned in the description of the invention, the clamp holder profile 2 of the claimed clamping device has an open longitudinal channel 6 adapted for the passage of the electric cables 11 that feed the presence sensors of the sheet to

    Stamping, as well as for the passage of the cables 10 pneumatic air inlet and outlet of the clamp 1.
    In the devices of the state of the art, the air circulation of the pneumatic circuit is carried out through internal channels 10 'provided in the same profile 2' clip holder, prior to transverse drilling of said interior channels 10 'through of the 8 'front connection plates. On the other hand, in the claimed clamping device, the air circulation of the pneumatic circuit is carried out at all times through the air inlet and outlet cables 10 that run, together with the electrical wiring 11, through the interior of the element 4a tubular to the open longitudinal channel 6, through the body of the support bracket 3a of said tubular element 4a. Thanks to this, the claimed device is very easy to handle, since the wiring is collected inside the tubular elements 4a and the clamp holder profile 2.
    Figures 5 and 6 show a sectional and perspective view of a section of a clip-holder profile 2 of the claimed device showing the open longitudinal channel 6 and the two front plates 8 connecting the input and output cables 10 of the pneumatic circuit that are housed inside said open longitudinal channel 6. The same figures show the cover 21 that covers the end of the clip-holder profile 2 and is adapted to connect all of the electric cables 11 to an external power cable, as well as the cover 20 that is coupled in some sections of the channel 6 open through the longitudinal grooves 7 of the clamp holder profile 2 to protect the ingress of dust in said longitudinal open channel 6 of the same clamp holder profile 2.
    As discussed in the description of the invention, the claimed clamping device has the advantage over devices of the state of the art that is light and easy to handle, so that it significantly improves the productivity and reliability of the stamping process
    Although reference has been made to a specific embodiment of the invention, it is apparent to one skilled in the art that the described device is susceptible to numerous variations and modifications, and that all the mentioned details can be replaced by other technically equivalent ones, without departing from the scope of protection defined by the appended claims. For example, although certain configurations of supports 3a, 3b for holding tubular elements of techno-polymer material have been represented and described, these configurations may vary depending on the orientation that
    it is desired to give the tubular support element and the spatial positioning required for the corresponding clamp. Similarly, although in the described embodiment, reference has been made to a support device for a pneumatic clamp 1, the same device 1 could be suitable for holding another type of non-pneumatic clamp that could also be used for hold sheets to be stamped in a press.
