Abstract
The invention discloses an aerodynamic forme clamping mechanism, which relates to a sheet-fed press, in particular to the forme clamping mechanism of sheet-fed press forme cylinders, and is characterized in that: the aerodynamic forme clamping mechanism comprises an upper printing clamp(1) which is fixed on the forme cylinder, a sliding lower printing clamp (2) which is made from cylinders, and a clamping spring (3) which makes an application of force on the lower printing clamp; a forme (11) is clamped between the upper printing clamp and a lower printing clamp. When the cylinder of the lower printing clamp is ventilated, the upper printing clamp and the lower printing clamp open, thus the aim of exchanging formes is realized.
Description
Technical field
The present invention relates to sheet-fed press, relate in particular to the clamping device of its plate cylinder.
Background technology
The clamping device more complicated of the plate cylinder of existing sheet-fed press, for example Chinese patent file CN1062497A once disclosed a kind of quick-gripping device, and what its following clamp bar used when unclamping forme is leverage, and its structure is as shown in Figure 1.Following clamp bar (2) is clipped in forme (11) between upper clamp bar (1) and the following clamp bar (2) after the contact-making surface slip of barrel (6) under the promotion of spring (3); Cylinder (5) is as power source, by lever (7) to clamp bar (2) application of force down, make its along the contact-making surface of barrel (6) to lower slider and compress spring (3), clamp bar is converted to open configuration from clamped condition up and down simultaneously, forme (11) is released.
This lever clamping device, what its following clamp bar used when unclamping forme is a kind of leverage, cylinder reaches the purpose of unclamping forme by leverage.Cylinder force drives following clamp bar by a series of attachment devices such as levers, its subject matter is that the arm of force of lever occupies certain space respectively with independent cylinder as power source in the groove of plate cylinder, make plate cylinder that the groove of clamp bar is installed, that has to design is bigger, but the groove of plate cylinder is big more, the surperficial utilization rate of plate cylinder is just low more, causes the printing machine overall structure to increase; On the other hand, the groove of plate cylinder is big more, and ink roller will be big more to the impact of plate cylinder, and this will strengthen the vibrations of printing machine, directly influence the quality of printed matter.Therefore novel high speed printing machine now requires narrow as far as possible with the plate cylinder groove design.Taking up space so reduce clamp bar mechanism, is that the printing machine designer is to one of improved emphasis of lithographic press.
Summary of the invention
The purpose of this invention is to provide a kind of clamping device that uses pneumatic mode on printing machine, forme to be fixed and discharged, further say so and directly cylinder is made down clamp bar, it has removed and has simplified the structure of original complicated lever clamp bar, effectively scaled down version is clipped in shared space in the plate cylinder groove, thereby has better met the design needs of modern printing machine.
The present invention is achieved in that a kind of Pneumatic power forme gripper mechanism, and it is contained in the groove of plate cylinder.Comprise: upper clamp bar, following clamp bar, fastening spring, the gap spring that disappears, reference column; It is characterized in that: a upper clamp bar and a following clamp bar of directly being made by cylinder that is fixed on the plate cylinder is arranged, following clamp bar can slide along the contact-making surface in the plate cylinder groove, when not having the compressed air supply cylinder, under the effect of fastening spring (3), following clamp bar is along slideway and upper clamp bar closure, and clamp bar is clamped forme up and down; When cylinder is supplied with compressed air, cylinder piston rod (12) withstands a position of barrel, an or position of withstanding upper clamp bar (1), an or position of withstanding the barrel connector, clamp bar (2) is slided towards the opposite direction that piston rod ejects, reach and open the purpose that clamp bar is put into forme or taken out the forme of having put into.On the preceding clamp bar reference column (4) is housed, the effect of reference column is when clamp bar opens up and down, the forme front end that will have matrix breach (13) inserts in the clamp bar, with the matrix notch alignment and insert in the reference column, realizes the front and back of forme and the accurate location of left and right directions.For increasing the chucking power of clamp bar, to the clamping face (14) of clamp bar and the processing (Fig. 7) that (15) have done spraying alloy sand grains respectively up and down.In addition, be provided with spring (10) for the glade plane space of eliminating down clamp bar.The present invention makes it compared with prior art owing to adopted above-mentioned technical scheme, has following advantage and good effect: with regard to the clamping device of forme, simplify the structure, directly and simple, mechanism controls is simple for transmission of power, manufacturing process is simple, has reduced manufacturing cost; With regard to regard to the improvement in performance of printing machine, it is littler that the space that has dwindled the plate cylinder groove just means that the cylinders of printing press diameter allows to do, thereby the structure of printing machine can be compacter; Reduced not only to have improved the quality of printing, also improved the upper limit of press speed by of the impact and the vibrations of version ink roller to plate cylinder.
