- a front and rear mounting plate 18, 19 fixedly mounted on a support structure 20.
- Mounting plates 18, 19 and the support structure 20 can be exchangeably attached to different workpiece holders, which work together on the processing device 10 with the respective existing tool.
- the front mounting plate 18 is parallel to the base plate 14 and thus usually aligned horizontally.
- the adjoining rear mounting plate 19 is at the back, to the existing in the region of the Einwölbstelle 21 curved plate 23 is present.
- the two attachment plates 18, 19 thus close an obtuse angle 25 of about 173 degrees in the present example case.
- the rear end of the rear mounting plate 19 is located at an approximately right angle 27 from below at the bottom of the present in the Einwölbstelle 21 plate 23 at. Forces acting from below on the rear mounting plate 19 thus act approximately in the normal direction on the underside of this curved plate 23. Such forces occur during operation of the device 10 when a workpiece holder is inserted inserted into the support structure 20, as will be described in more detail below ,
- Pressenbär bracket 22 in a linear direction (adjustment) 24 mounted on the press frame 12 adjustable.
- the support structure 20 has left and right abutment plates 30, 32.
- the two plates 30, 32 are welded perpendicular to the base plate 14. They are arranged parallel to one another, with a clearance 34.
- an abutment plate 38 is firmly welded to the two plates 30, 32. Through this abutment plate 38 engages a screw member 40 therethrough.
- a pivot member 42 (Fig. 4).
- This pivot member 42 is formed approximately rod-shaped and protrudes with its upper portion 44 in a centrally located in the front mounting plate 18 hole 46 into it.
- the screw member 40 is more or less oppressive.
- By more or less screwing the screw member 40 in the abutment plate 38 pivots its front end by its pressing system at the lower portion 50 of the pivot member 42 latter around its upper portion 44 in the counterclockwise direction (arrow 52).
- One in a - with reference to the figures - right concavity 54 of the pivot member 42 transverse transverse bar 56 is moved in this pivotal movement 52 to - in Fig. 4 - right, in the direction of arrow 58.
- the two cantilevers 70, 72 which are mounted at right angles cantilevered to the lower part 76 of the bending tool, are arranged parallel to each other and have a mutual clearance 80, which in the present example is greater than the outer distance 82 of the two abutment plates 30, 32 of the support structure 20.
- the two cantilevers 70, 72 can thus be pushed from the front side of the frame to the same, wherein the left and right cantilevers 70, 72 on the respective outer side of the two abutment plates 30, 32 are present.
- the two cantilever plates 70, 72 are pushed onto the support structure 20 in such a way that the holes 64, 66 present in their two plates 70, 72 are aligned with the upper region of the slot 60.
- the two plates 70, 72 are provisionally held in the support structure 20, insofar as they can no longer be withdrawn from the frame 12 backwards.
- the upper sides 86 of the two cantilever plates 70, 72 are like the two mounting plates 18, 19 roof-shaped, with the same obtuse angle 25, as it is present between the two mounting plates 18, 19, formed between them, so that the two cantilevers 70, 72 in the fully inserted into the support structure 20 state from below press against the two mounting plates 18, 19.
- the two attachment plates 18, 19 project beyond the two abutment plates 30, 32 in each case in the lateral direction to some extent.
- the screw member 40 For releasing and pulling out of the two plates 70, 72 from the support structure 20, the screw member 40 is pulled out in accordance with another direction of rotation a distance from the abutment plate 38 to the front. As a result, the screw member 40 loses its pressing contact with the pivot member 42. As a result, the pivot member 42 pivoted back in the opposite direction and then the crossbar 56 are pulled out of the support structure and thus also from the two plates 70, 72 of the respective tool. Subsequently, then - based on the Fig. 2 - the lower part 76 of the bending tool from the support structure 20 are pulled to the left.
- the upper part 77 of a bending tool 75, of which the lower part 76 is shown in FIG. 2, can be designed as shown in FIG. 3.
- FIG. 3 shows a bending tool 75 whose lower part 76.3 corresponds in principle to the lower part 76 (FIG. 2), with the difference that lateral, upwardly projecting limiting rails 87, 88 are attached.
- the boundary rails 87, 88 serve as a kind of aperture as each side protection device.
- the upper part 77 is shown at a distance 89 to the lower tool part 76.3 and is attached to an upwardly projecting neck-like fastening part 90 interchangeable in a conventional manner.
- the fastening part 90 can by means of four screws (holes 105) in the present example in turn be firmly screwed from the front to a retaining plate 92.
- an aligned in the adjustment direction 24 elongated slot 94 is present, in which the rectangular projection 96 of the holder 22 is immersed from behind.
- the slot 94 is present in an alignment plate 98, which is firmly screwed by means of lateral two screw holes 100, 102 in two slots 101, 103 of the fastening part 90 with lower pivoting possibilities.
- the alignment plate 98 abuts the retaining plate 92 at its upper and lower ends 104, 106 in the drawing, so that compressive forces can be transmitted between the alignment plate 98 and the retaining plate 92 in this region.
- the alignment plate 98 Above and below the elongated slot 94, there is an upper hole 110 and a lower hole 112 in the alignment plate 98. These two holes 110, 112 correspond to an upper and a lower screw hole 114, 116 which are present above or below the projection 96 of the holder 22. About the two holes 110, 114 and 112, 116, the alignment plate 98 and thus the support plate 92 are screwed to the front side of the bracket 22 by means of two mounting screws 118. When adjusting the projection 98 in the adjustment direction 24, the support plate 92 is adjusted accordingly. In this way, attached to the support plate 92 upper part 77 can be moved in the adjustment direction 24 back and forth.
- the two holes 110, 112 present for fastening the alignment plate 98 to the projection 96 are aligned with two holes 120, 122 on the fastening part 90, so that fastening can take place via the two fastening screws 118.
- the fastening part 90 sits from the front against the retaining plate 92 and thus also from the front on the alignment plate 98.
- a tool 75.5 is shown, the upper part 77.5 both on the front side of the projection 96, in a similar manner as the upper part 77, can be attached and at the same time engages in a present in the lower end face 130 indentation 132 from bottom to top.
- Such a tool can be used for example for pressing parts into a workpiece.
- a downwardly directed punch 134 is present, which is aligned in the adjustment direction 24 with a rod-shaped in this case die 136.
- the die has a central recess 138 in which the punch 134 can dip from above.
- the indentation present in the lower end face 130 can also serve as the sole fastening device for a tool.
- the upper portion 77.5 has a mounting plate 140 having a central mounting hole 142 through which this mounting plate 140 can be secured to, for example, the lower hole 116.
- the attachment plate 140 Above the attachment hole 142, the attachment plate 140 has a central upwardly open slot 144, the clear width 146 of which corresponds to the width 148 of the projection 96. In the attached state, the mounting plate 140 therefore can not pivot on the bracket 22.
- a cantilever 150 is firmly attached on the mounting plate 140 is below, at right angles to the same.
- a bolt member 152 is attached, which is fastened at the top, in the adjustment direction 24, projecting on the cantilever plate 150.
- the mounting plate 140 When attaching the upper part 77.5 on the upper bracket 22, the mounting plate 140 is pushed from below onto the projection 96. In this case, the bolt member 152 immersed in the present in the lower end 130 Einwölbung. Subsequently, the mounting plate 140 is then secured through the mounting hole 142, for example, to the lower hole 116 of the bracket 22.
- the upper part 77.5 of a corresponding tool is thus arranged not only on the front end side of the holder 22, but also from below in the upper holder 22 fixed and immovable.
- the punch 134 When pressing the Einpresstechnikmaschinees so the punch 134 can not pivot out of its aligned with the adjustment direction 24 alignment out, since the upper part 77.5 not from the upper bracket 22 in consequence of the force acting on the upper part 77.5 laterally or forward or forward can pivot back from the direction 24; the latter is prevented by the seat of the bolt member 152 in its immersion in the lower end face 130.
- the die 136 In alignment with the punch 134, the die 136 is interchangeably attached to the lower part 76.5 via a corresponding insert 160 on a left and right cantilever plate 70.5 and 72.5.
- the cantilever plates 70.5 and 72.5 correspond to the two cantilever plates 70, 72 shown in Fig. 2. In this way, the lower part 76.5 in the same manner as the lower part 76 in the support structure 20 (Fig. 2) mounted and released again.
- Fig. 6 the two cantilevers 70, 72 of the lower part 76 of the corresponding bending tool are shown pulled apart.
- the two plates 70, 72 are formed by a vertical transverse plate 170 and a horizontal transverse plate 172 in the assembled state as a stable body.
- these are dovetailed together and welded together in the tapped area.
- slot-like holes 174, 176 are present in the two plates 70, 72, which correspond in cross-section to the pins 178, 180, which are cantilevered in the two transverse plates 170, 172.
- the pins 178 of the horizontal transverse plate 172 dip into the respective slot-like holes 174 of the two plates 70, 72.
- the pins 180 of the vertical transverse plate 170 also dip into the slot-like holes 176 of the two plates 70, 72.
- the cross-section of the respective pins are adapted to the clear dimensions of the slot-like holes that they can be inserted with little play in the slot-like holes.
- the Kragin 182 each pin 178, 180 smaller, in the present case about half as large as the thickness 184 of the relevant plate.
- the hole space 186 not filled by the slot 178 or 180, respectively, of the slot-like hole 174 or 176 is filled with welding material 188 after the plates have been plugged together.
- the nested respective plates are firmly welded.
- the plates and thus the frame 12 can be assembled with it without this elaborate fixtures must be made and used; the nested frame parts create a sufficiently stable for welding frame, which can be welded without problems to a rigid spatial structure.
- the deformations occurring during the welding process can be kept desirably small.
- the holder 22 is attached to the front end 226 of a rocker member 228 so that when up and down rocking the rocker member 228, the bracket 22 in the adjustment direction 24 linearly reciprocated.
- the rocker member 228 consists of two rocker plates 230, 232 arranged parallel to one another. Between the rocker plates 230, in the region of the front end 226, a circular disk-shaped pressure member 234 is secured, which presses into a sickle-shaped or moon-shaped receptacle 236 of the holder 22 (FIG. 9). , The mutual abutment of the pressure member 234 and the receptacle 236 allows the rocking movement of the front end 226 along a circular arc and the linear adjustment of the holder 22 to fit together.
- the rocking movement of the rocker member 228 and thus the linear adjustment of the holder 22 is effected by an actuated by hand or by foot an operator actuator 240.
- the actuator 240 has a first hinge rod 242, which is about a first fixed to the press frame 12 pivot axis 244 from its drawn in Fig. 9 position in its drawn in Fig. 10 position and back and forth back and forth.
- the first hinge rod 242 is hinged to a second hinge rod 46 by means of a hinge 248.
- the other end of the second hinge rod 246 is hingedly connected via a hinge 50 to a third hinge rod 252.
- This third articulated rod 252 can be swiveled back and forth about a second rotation axis 254 fixedly mounted on the press frame 12.
- FIGS. 9 and 10 The two pivot end positions of this third joint rod are shown in FIGS. 9 and 10.
- a fourth joint rod 258 is articulated via a joint 256.
- This fourth articulated rod 258 is hinged to the rear end 260 of the rocker member 228 by means of a hinge 262.
- the third hinge rod 252 is now formed so that the hinge 250 (mounting location of the second hinge rod 246) has a much greater distance from the second fixed axis of rotation 254 than the hinge 256 (mounting location of the fourth hinge rod 258). Due to the circular movements of the joints 250, 256 about the second axis of rotation 254, the vertical component of movement of the joint 256 is very small compared to that of the joint 250 in the last stroke of the fourth joint rod 258. This means that a comparatively large force acts on the rear end 260 of the rocker member 228 during this last stroke movement.
- pivot rods and their stationary pivotal mounting on the first and second fixed axes of rotation 244, 254 are such that in the illustrated in Fig. 9 adjustment of the actuator 240, the bracket 22 is in its upper working position. This means that the front end 226 of the rocker member 228 has pivoted maximally upwards and the rear end 260 of the rocker member 228 has pivoted maximally downwards.
- the rocker axis for the rocker member 228 is represented by a wave-shaped cantilever 264, which engages in a shaft having a through hole 266 in the rocker member 228.
- This cantilever element 264 is attached cantilevered to a rear retaining plate 268, which is not visible in FIG. 9 for reasons of clarity, but can be seen in FIG. 8.
- the holding plate 268 is provided on the outside laterally adjacent to the rear rocker plate 232.
- front rocker plate 230 is also a holding plate 270 is provided on which a cantilever member 24 comparable cantilever member 274 is cantilevered.
- the two cantilever members 264, 274 are mounted parallel to each other at the respective holding plate 268 and 270, respectively. They project in mutually opposite directions in each case in the direction of the rocker member 228.
- the two holding plates 268, 270 have such a mutual distance from one another that by reciprocating the fixed by a mounting rod 276 two holding plates 268, 270 in the direction of movement 278 always only one of the two cantilevers 264 and 274 in the rocker member 228 transversely surfaced.
- the right Kragglied 264 dips into the through hole 266 of the rocker member 228 in Fig. 8.
- the two retaining plates 268, 270, the left in Fig. 8 cantilever member 274 does not engage in a in the two holding plates 268, 270 existing common bore 275 inside. Therefore, only the right cantilever 264 is effective as a rocker axis for the rocker member 228.
- Fig. 10 the maximum lower working position of the holder 22 is shown.
- the upper end 279 of the holder 22 abuts against a height-adjustable stop 280 from above (FIG. 8).
- the attachment is made on an adjustable screw 282, which is fixed to the upper end of the press frame 12 together with a holding lug 284.
- the press frame 12 and thus the processing device 10 can be attached and moved back and forth.
- the rear, left Kragglied 274 acts as a rocker axis for the rocker member 228.
- the latter is achieved in that the two holding plates 268, 270, on which the two cantilevers 264, 274 are cantilevered, after - relative to the Fig. 8 - are shifted to the left.
- the displacement is effected in the present example case by means of a pivoting lever 286 which pivots back and forth by means of a molded handle 288 (bow arrow 920) and thereby by means of its front fork-like prongs 292, the two holding plates 268, 270 in the one and in the other direction of movement 278th shifts.
- the direction of movement 278 in this case runs parallel to the respective rocker axis, that is to say parallel to the cantilever axis of the two cantilever members 264, 274.
- the two tines 292, or the two retaining plates 268, 270 could also be moved back and forth directly by hand or optionally also by motor.
- the adjustment of the rocker member 228 about the rearward rocker member 274 causes the forward end 226 of the rocker member 228 to be farther from the rocker member 274 than is the case with Figures 9 and 10.
- the through hole 266, namely, the cantilever member 264 does not engage in the rocker bearing according to FIGS. 11 and 12; in contrast, the other cantilever member 274 protrudes into the rear throughbore 275.
- the two through holes 266, 275 lie on a line 292, the Joint 262, with the rear end 260 of the rocker member 228 is hinged to the fourth hinge rod 258, crossed.
- first and the third joint rod as well as the rocker member 228 in two parts, with two mutually parallel plates formed.
- the respectively intermediate second and fourth joint rods are integrally formed, each with a plate-shaped rod.
- the actuator 240 may be operated via a hand lever 310.
- a hand lever 310 such a hand lever on a coupling rod 312 in its orientation to the same adjustable but firmly attached.
- the hand lever 310 are aligned differently in its orientation to the coupling rod 312.
- the hand lever 310 is fixed to the coupling rod 312 through the center hole 315 except through the screw hole 313.
- the hand lever 310 can also be fastened by the screw holes 314 or 316 adjacent to the screw hole 315.
- the coupling rod 312 is in turn rotationally fixed to the second fixed axis 254.
- the coupling rod 312 pivots along the arrow 322 and thus also in a clockwise direction.
- the third hinge rod 252 is also moved clockwise about the second fixed axis 254 (arrow 324).
- the pivotable rocker member 228 moves with its rear end 260 upwards.
- the front end 226 of the rocker member 228 moves down and thereby enters its illustrated in Fig. 10 lower working position. In Fig. 13, the upper, shown in Fig. 9 other extreme working position is shown.
- the actuating device can also be effected by a foot operation.
- a carriage 330 is shown schematically, which can be pushed along a slide guide 332 by more or less vigorous foot movement in the direction of the arrow 334 from its rest position shown in FIG.
- the carriage is attached via a rectilinear hinge rod 336 which is hinged to an angle bar 338.
- the angle bar 338 is fixed in rotation with its other end to a coupling rod 340.
- This coupling rod 340 is fixed at its other end to the first stationary axis 244 rotationally fixed.
- the actuator 240 and its hinge rods is also rotated accordingly, so that depending on the effective rocker axis, the bracket 22 from its upper position in its lower position shown in FIG. 10 or FIG. 12 is adjusted.
- the movement of the carriage 330 back from its working position 330a shown in dashed lines in FIG. 14 is generally carried out by retracting the foot of the person operating the device from the carriage.
- this movement is supported by an elastically deformable spring member 344.
- the spring member 344 is forced apart so that the carriage 330 is subsequently moved back from its working position 330a to its rest position 330 by the spring member 344.
- the carriage 330 may be operated by a standing operator. The person does not have to sit in order to operate by foot the known in the art pivot lever and get up to operate the machine.
- the carriage 330 is present by the measure 326 above a footprint 328. This allows an operator to stand with one foot on the slide during its entire reciprocation and with the other foot while standing on the floor 328.
- the C-shaped press frame 12 is loaded by the bearing force of the rocker member 228. This bearing force acts in the axis of the respective cantilever member 264 or 274. While in the prior art, a corresponding bearing force in the line of action of the holder 22 acts, the line of action 346 of this bearing force in the apparatus 10 according to the invention - in relation to FIG. 9 - left shifted , The line of action 346 thus has a comparatively smaller distance D1 from the concavity point 21 or smaller distance D2 from the bulge point 350. The forces pushing the side walls apart at the point 21 and compressing at the point 350 are therefore lower in comparison with the prior art.
- the press frame 12 can be made comparatively easier constructive.
