Definitions

  • the present invention relates to a Punch press with at least one tool device, which punch press has at least one ram and one machine frame has, and which plunger by means Ram guides in the machine frame, which Tool device an upper tool unit, a lower tool unit and an arrangement of guide devices has, by means of which the upper tool unit for a movement in the stroke direction of the ram is guided in the lower tool unit.
  • Each module forms one complete tool with a tool head and a tool base and guides some, but not all processing steps on the belt to be processed by. That means that in the punch press several in Direction of passage of the strip to be processed successively Arranged modules are built in with respect on the entire processing process together form a long follow-up tool.
  • the upper part of the tool which is in operation of the punch press moved, relative to the lower tool part by column guides guided, the upper part of the tool is in operation moving guide elements in the form of guide columns has, which in as fixed guide members acting column guides in the lower part of the tool are, i.e. the pillars are at leadership positions in led the column guides, and there usually four Guide columns and column guides are present, determine the management positions together the management level of the module.
  • the advantage of the modular design is general in the rational production of the tools, in the interchangeability (e.g. for regrinding some worn ones Tool parts), and easier handling.
  • the upper frame part has guide columns as moving links in the company on and the lower part of the frame has column guides as fixed links in the company.
  • another management level namely determine the management level of the mother rack.
  • the upper frame part the mother frame with the ram of the punch press and the lower part of the frame is connected to the platen, which the latter with the machine frame of the punch press is firmly connected.
  • the tappet is equipped with guide columns, which are guided in column guides in the machine frame are.
  • the punch press is also a leader (in the column guides) present together yet another, i.e. determine third management level.
  • the first management level is through module tours between the module module upper part and the module lower part certainly.
  • the second management level is through the mother frame guides between the upper frame part and the lower frame part of the mother frame certainly.
  • the third management level is through the ram guides between the ram and the machine frame the punch press.
  • the invention seeks to remedy this.
  • the Invention as characterized in the claims solves the task of a punch press with a tool device to create a minimal number of bearings needed for guidance in the stroke direction and by means of which different thermal expansions practically lossless can be picked up by the upper tool unit the tool device by means of connecting units directly with a section of the punch of the punch press is connected, which is only transverse to the stroke direction running displacement between the upper tool unit and allow the pestle.
  • Figure 1 shows the ram 1 of a punch press, which is articulated in a known manner on pressure columns 2, which in turn are articulated on one-armed levers 3.
  • One end of the one-armed lever 3 is articulated on a connecting rod 4, which is mounted in a known manner on an eccentric shaft (not shown) or crankshaft.
  • the one-armed levers 3 are articulated on devices 5 for adjusting the ram height.
  • the rotary movement of the eccentric or crankshaft is converted into a translatory movement by the connecting rod, which is transmitted to the plunger 1 by means of the one-armed lever 3.
  • This arrangement and operation including the ram height adjustment is generally known and thus need not be described in detail.
  • the ram is connected to guide columns 6, which are guided in column guides 7.
  • This from the Guide columns 6 and column guides 7 existing guide arrangement and their mode of operation is in CH-A-568 848 and US-A-3 998 498, respectively, and it hereby expressly states the disclosure of these documents pointed.
  • the specific arrangement of the column guides 7 and in particular the course of their sliding surfaces can be seen from Figure 2.
  • the through the Guide pillars 6 and pillar guides 7 certain management level coincides with the tape running level, which through the two outer sections of section line II-II is shown in Fig. 1.
  • the column guides 7 are with connected to the machine frame 8. On the machine frame 8, a platen 9 is screwed on. Further is an alignment plate 10 screwed to the platen 9.
  • the plunger shown in the drawing figures 1 has a lower section 11 which is plate-shaped trained and rigid with the remaining plunger 1 connected is. However, it should be clearly stated that the entire plunger 1, 11 is formed in one piece can be, so that the parts 1, 11 an undivided Form workpiece.
  • the drive is from the connecting rod 4 over the one-armed lever 3, 3 '.
  • These double levers 31, 32, 33, 34 act on the pressure columns 35, 36, 37, 38 Tappets 13, 11 and 14, 11 '.
  • the plungers 13, 11 and 14, 11 ' are listed in three places, the two in the figures 3 and 4 outermost guides equal to that in the figure 1 and 2 guides are formed.
  • the plungers 13. 11 and 14, 11 ' can move from the points O, O 'towards the Extend arrows k, l, m and n, o, p freely, with that of most distant modules 12 am most severely affected by the occurring changes in length are and in particular they can freely expand in the direction of arrows m and n.
  • the module 12 i.e. the tool device, has an upper tool unit 17.
  • This upper tool unit 17 is located directly at the bottom of the Plunger 1, 11, with the drawn version the ram section 11 as one with the rest of the ram 1 screwed plate is shown, which two-part Ram design is not mandatory.
  • the Plate 11 could just as well be a one-piece section of the entire ram.
  • the lower tool unit 20 is still in one to be described by means of bolts 21, 22 with an alignment plate 10 screwed, which in turn by means of bolts 23, 24 with the clamping plate 9 is screwed.
  • the module 12 shown is one, for example Execution of a tool and it is for the Professional obviously that it is with tools for Stamping presses are very different designs, each after the processing to be carried out on the line.
  • Tool device i.e. Tool device has a stamp holding and pressure plate as the upper tool unit 17 25, in which a stamp 26 is inserted, and has a guide or stripping plate 27.
  • the lower tool 20 has a cutting and Pressure plate 28 on.
  • the guide plate 27 is also by means of Linear ball bearing 45 on the guide columns 65, 66, 67, 68, guided.
  • the stamp 26, which with the stamp holder 25th connected extends through this guide plate 27.
  • the guide plate 27 is screwed into it Bolt 43 carried in the stamp holding plate 25 and through Compression springs 44 clamped away from the same.
  • the reference number 47 denotes the sheet metal strip to be processed.
  • Precise bores are in the alignment plate 10 50 and in the pressure plate 28 are precise positioning holes 51 trained. After the module 12 by means of the stops 48, 49 have been roughly aligned, the positioning holes 50, 51 with each other exactly aligned and precisely machined positioning sleeves 52 through the positioning holes 51 into the positioning holes 50 inserted so that the lower tool unit 20 arranged exactly on the alignment plate 10 and is therefore aligned with the upper tool unit 17 is. Then the attachment takes place using the Bolts 21, 22, but only as a connecting element elements between the lower tool unit 20 and the alignment plate 10 and not as lateral guide elements serve.
  • the upper punch holding plate or pressure plate 25 is by means of bolts 58 with the plate 11, that is, directly with a section of the ram of the punch press, connected, which are surrounded by bushes 54.
  • holes 55 are formed in the stamp holding plate 25 .
  • the outside diameter of the inside diameter corresponds to the holes 55. This makes the pestle relative aligned to the upper tool unit 17 and centered.
  • the bolts 58 are loosened again and the auxiliary rifles used for alignment replaced by bushings 54, whose outer diameter is smaller than the inside diameter of the bores 55, so that a game S allowing horizontal displacement is available.
  • the length of the sleeves 54 is on the thickness of the flange 56 matched so that after tightening the bolt 58 with a fixed Torque between the thrust washer 57 and the flange 56 there is a minimal game.
  • the alignment plate 10 consist of several parts, each "Plate section” 11 and each "alignment plate section” 10 carries part of the total modules 12.
