Definitions
- the invention relates to a sheet metal forming machine, and in particular a drawing press for the serial production of large body-in-white parts, according to the preamble of claim 1.
- the upper and lower tools form a uniform tool group that is interchangeable as a whole as well is transportable and storable and for this purpose, but also for manufacturing reasons, in addition to the molded parts (stamp and die) and the sheet holder made of upper and lower, molded part-specific base beams exists, which are permanently connected to the associated molded part and the corresponding centering of the mutual centering of the Take over the molded parts and the sheet metal holder.
- Such a design is however with a high manufacturing effort, because for every new sheet metal part geometry a separate tool group with sheet metal-specific molded parts, Basic supports and associated sheet metal holder must be made.
- the object of the invention is a sheet metal forming machine of the type mentioned To be designed in such a way that the production costs for the tool and lower parts is significantly reduced.
- the use of molded parts makes them more independent Basic bars, including the guide surfaces in standardized, reusable Design for a variety of differently designed Sheet-specific stamps or dies can be used, not just the one Transport, stackability and replacement of the individual tool assemblies simplified, but especially in connection with the massive Steel construction of the molded parts, through which - unlike molded parts in Cast and / or rib construction - easy post-processing and adjustment of the shaping tool surfaces to changed sheet metal part geometries enables the planning and investment costs for the tool side Assembly reduced significantly.
- the basic carrier in an advantageous embodiment of the invention according to claim 2 arranged on the molded part with rasterized Attachment points provided while the corresponding attachment points on the molded part, specific to the molded part, but taking the grid dimensions into account are positioned.
- the Sheet metal holder with a small change in the sheet metal part geometry Workload, namely simply by reworking its clamping surface, reusable that it is also made from a solid block of steel and formed on the part of the associated base support independently of the sheet metal part and is guided smoothly.
- the base carrier are preferred for manufacturing reasons as Castings are formed, and the molded parts and / or sheet metal holders are on the Sheet metal or clamping surfaces are surface-coated, which means even for high-strength ones Steel sheets a high quality workmanship is guaranteed.
- FIG. 1 shows a drawing press with a hydraulically operated press ram 1, a press table 2 and one arranged below the press table 2, also hydraulically operated lifting plate 3, which is uniformly denser Distribution with pressure bolts 4 reaching through the press table 2 for actuating the sheet metal holder is occupied.
- the drawing press is more conventional Construction.
- the lower tool 5 and the upper tool 6 of the drawing press form a uniform, as a whole, transportable and storable, at the press table 2 or press ram 1 interchangeable clamped assembly and each exist from a base support 7 or 8, a molded part attached to this, that is a punch 9 or a die 10, and a sheet metal holder 11 on the lower tool 5.
- the base beams 7, 8 are made as rib castings, are the molded parts 9, 10 and the sheet metal holder 11 made of solid steel blocks manufactured and on their shaping tool surfaces 12, 13 and Clamping surface 14 of the sheet metal holder 11 has a surface finish.
- the base beams 7, 8 are independent of the spatial shape of the Molded parts 9, 10 and the sheet metal holder 11 are formed and because of their standardized Design for a variety of different stamps 9 and sheet metal holders 11 or matrices 10 can be used.
- the base beams 7, 8 are each with threaded holes 16 arranged in a grid pattern and uniformly distributed provided, while the corresponding counter bores 17 on the punch 9th and the die 10 differ depending on the spatial shape of the molded part 9, 10, but positioned taking into account the pitch of the threaded holes 16 are, so that differently shaped parts 9, 10 permanently with screw the associated base support 7, 8.
- the exact positioning the molded parts 9, 10 on the base support 7 and 8 is by - Not shown - dowel pins and holes.
- the sheet metal holder 11 is on its outer contour regardless of its sheet metal part-specific clamping and Interior surface shape adapted to the standardized basic carrier geometry and for centering the stroke also with guide surfaces 19, which with corresponding Counter surfaces 20 cooperate on the base support 7, provided.
- the lifting actuation of the sheet metal holder 11 is carried out by on the lifting plate 3 arranged pressure pin 4 with the interposition of sheet metal holder-specific arranged on the underside of the sheet metal holder 11, in the base support 7 guided intermediate plungers 21.
- the corresponding Receiving openings 22 in the base support 7 again in a grid pattern uniformly distributed so that the base support 7 for sheet metal holder 11 with under Pay attention to the spacing of the intermediate rams positioned differently 21 can be used.
- the grid dimension of the receiving openings 22 corresponds to the Distribution of the pressure bolts 4 on the lifting plate 3 such that all Push pin 4 during the upward stroke of the lifting plate 3 on the press table side Support surface of the base support 7 raised and then the Actuating sheet holder 11 solely by the sheet holder specific arrangement the intermediate plunger 21 can be selected without having to change the sheet metal holder Excess pressure bolts 4 are removed or missing ones are added have to.
