Description

    The present invention relates to a mold mounting position correction apparatus for a press machine, and more particularly to an apparatus for correcting a displacement of a mold mounting position accompanying deformation of the press machine.

    A general press machine (crank press having a straight side frame) A shown in FIG. 16 includes a bed B, a bolster C, a column D, a crown E, a slide S, and the like, and is installed between the bolster C and the slide S. A material (not shown) is set between the mold G, specifically, an upper mold U attached to the lower surface of the slide S and a lower mold L attached to the upper surface of the bolster C. By applying pressure, a product having a predetermined shape following the mold G is press-molded.

  Here, in the above-described conventional press machine A, in a load state in which a pressurizing force (arrow F in the figure) is applied, the bed B and the bolster C are caused to react by the reaction force of the pressurizing force as indicated by a chain line in the figure. On the other hand, the crown E and the slide S are deformed in such a manner that they bulge upward.

  By the way, even if the same pressing force is applied using the same mold, if the press machine to be used is different (same model, different machine), it depends on factors such as the rigidity of the press machine used and aging The degree of deformation in each part, such as a bolster and a slide, varies depending on the press machine.

  In this way, the bolster C and the slide S are deformed by the reaction force of the applied pressure, so that the lower mold L mounted on the upper surface of the bolster C and the upper mold U mounted on the lower surface of the slide S are also being pressed. Then, the bolster C and the slide S are deformed, and there is a possibility that the accuracy of the press-processed product or the die G is damaged.

  Therefore, in order to eliminate such inconvenience, conventionally, by inserting a shim between the upper surface of the bolster C and the lower surface of the lower mold L and between the lower surface of the slide S and the upper surface of the upper mold U, Measures are taken to offset the deformation of the bolster C and the slide S during press working.

Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments.
1 to 3 show an example in which a mold mounting position correcting apparatus according to the present invention is applied to a press machine for processing a metal sheet material into a panel having a desired shape, for example, in an automobile production factory. Note that the overall configuration of the press machine is basically the same as that of the conventional press machine A shown in FIG. 16, and therefore a detailed description of the overall configuration of the press machine is omitted.

  As shown in FIGS. 1 and 2, a correction unit (die attachment position correction device) 10 described in detail below is attached to a lower surface 2a of a slide (die support body) 2 constituting the press machine 1. Yes.

  The correction unit 10 is an attachment retrofitted to the existing press machine 1 and is substantially attached to the lower surface 2a of the slide 2 as described above, thereby substantially constituting a part of the slide 2.

  That is, in a state where the correction unit 10 is attached to the slide 2, the mold support body is configured by the slide 2 constituting the mold support body and the correction unit 10 attached to the slide 2. The lower surface of the material constitutes a substantial mold mounting surface.

  The correction unit 10 includes a base plate 11 attached in close contact with the lower surface 2 a of the slide 2, and a mounting plate 12 that is spaced apart from the lower region of the base plate 11. An upper die (die) 100 as shown in FIG. 9 is attached to the lower surface (die attachment surface) 12A.

  Between the base plate 11 and the mounting plate 12, a total of 26 clampers 13, 13... Composed of hydraulic cylinder actuators are distributed as shown in FIG. Based on the operation of 13, the guide block 14 is guided by the pair of guide blocks 14 and 14 so as to move in the direction of approaching / separating from the base plate 11.

  Further, a total of 40 adjusters 20, 20... Are installed between the base plate 11 and the mounting plate 12 in the correction unit 10, and the adjuster 20 adjusts the pressing plate 12 as will be described later. 21. These adjusters 20 (adjustment blocks 21) are laid out in a 4 × 10 lattice pattern as shown in FIG.

  As shown in FIGS. 3 to 8, the adjuster 20 has a housing 20H fixed to the lower surface 11a of the base plate 11. The housing 20H includes the above-described adjustment block 21 and a wedge block (described later). Each wedge member 22 is supported so as to be movable.

  The adjustment block 21 is provided so as to freely move in a direction approaching / separating from the base plate 11 while being guided by the housing 20H and a pair of plates 20A, 20A attached to the housing 20H.

  The lower surface 21a of the adjusting block 21 is in contact with the upper surface 12u of the mounting plate 12. On the top of the adjusting block 21, an inclined surface 21c as a cam surface having a gradient of about 1/20 is formed. ing.

  On the other hand, the wedge block 22 is located above the adjustment block 21, and is provided so as to be movable along the horizontal direction while being guided by the housing 20H and a pair of plates 20B and 20B attached to the housing 20H. It has been. Further, an inclined surface 22c as a cam surface having a gradient of about 1/20 is formed on the bottom of the wedge block 22.

  Here, as shown in FIGS. 7 and 8, the adjustment block 21 is inserted with a slide pin 20P penetrating through an opening 220 formed in the center of the wedge block 22 and extending downward from the housing 20H. The adjustment block 21 is biased upward by the spring 20S interposed between the slide pin 20P and the inclined surface 21c of the adjustment block 21 and the inclined surface 22c of the wedge block 22 are always in contact with each other. .

  A drive screw shaft 31 extending in the moving direction of the wedge block 22 and penetrating the wedge block 22 is rotatably supported on the housing 20H. A screw portion 31s of the drive screw shaft 31 is supported by the wedge block 22. And a nut member 32 fixed to the screw.

  A motor 33 as a drive source is fixed to the housing 20H, and a drive gear 34 fixed to the drive shaft 33A of the motor 33 is fixed to one end of the drive screw shaft 31. It meshes with the driven gear 35.

  When the motor 33 is operated, the drive screw shaft 31 is rotated via the drive gear 34 and the driven gear 35, and the wedge block 22 is advanced and retracted in the horizontal direction by the screwing of the nut member 32 with respect to the drive screw shaft 31. The inclined surface 22c of the wedge block 22 and the inclined surface 21c of the adjustment block 21 are in sliding contact with each other, and the adjustment block 22 moves up and down by the cam action at that time, that is, moves in a direction approaching / separating from the base plate 11. It becomes.

  As described above, the motor 33, the drive gear 34, the driven gear 35, the drive screw shaft 31, the nut member 32, and the wedge block 22 constitute the drive means 30 for moving the adjustment block 21. The means 30 is nothing but a wedge mechanism that moves the adjustment block 21 by a cam action accompanying the advancement and retraction of the wedge block 22.

  In addition, an encoder (sensor) 40 for detecting the rotational speed of the drive screw shaft 31 is provided at the other end of the drive screw shaft 31 linked to the motor 33 via the drive gear 34 and the driven gear 35. The encoder (sensor) 40 detects the amount of movement of the adjustment block 21 based on the rotational speed of the drive screw shaft 31.

  Further, as shown in FIG. 6, the motor 33 and the encoder 40 in the adjuster 20 are both connected to a controller (control means) 50, and the controller 50 controls the adjustment block 21 based on information from the encoder 40. The movement dimension of the mounting plate 12 accompanying the movement is calculated, and the driving means 30 in the adjuster 20, specifically, the motor 34 is adjusted so that the movement dimension of the mounting plate 12 is set to a desired movement dimension set in advance. It controls the operation. Incidentally, it goes without saying that the controller 50 controls the operation of the 40 adjusters 20, 20,... In the correction unit 10 in an integrated manner.

  Here, as shown in FIG. 9, the upper mold (mold) 100 mounted on the lower surface (mold mounting surface) 12A of the mounting plate 12 is provided with a number of recesses 101, 101... For the purpose of weight reduction and the like. Thus, a large number of ribs 102, 102... Are formed on the upper surface (mounting surface) 100A, and the shape (layout) of these ribs 102, 102.

  In order to correct the displacement of the die mounting position accompanying the deformation of the press machine 1 by the correction unit 10 having the above-described configuration, the deformation mode of the slide 2 in the loaded state is collected as numerical data as a preparation.

  First, as shown in FIG. 10A, the state in which the slide 2 is deformed in a load state is reproduced by an appropriate means, and a laser range finder (not shown) placed on the bolster C on the bed B is used, for example. The distance from the predetermined reference surface fb to all points (denoted as p1 to p6 in FIG. 10) on the lower surface (die mounting surface) 12A of the mounting plate 12 pressed by each adjustment block 21 of the correction unit 10. Measure l1-l6.

  Here, when measuring the distances 11 to 16 as described above, each of the adjustment blocks 21, 21... Is occupied at the initial position, whereby the mounting plate 12 of the correction unit 10 is slid (die support body). ) It is assumed that it is deformed following the lower surface 2 (original mold mounting surface) 2a.

  Next, the standard distance ls from the reference surface fb to the reference surface ft, that is, the ideal mold mounting surface (ft) in a state where the slide 2 is not deformed is measured, and the standard distance is measured from the previously measured distances 11 to 16. By subtracting ls, deformation amounts d1 to d6 at points p1 to p6 (all points where the adjustment block 21 is located) are calculated as shown in FIG.

  The measurement of the deformation amount as described above is performed on each point of the lower surface 2a of the slide 2 with the correction unit 10 not mounted (the adjustment blocks 21, It is also possible to measure the amount of deformation at a point corresponding to 21.

  As described above, after the deformation of the slide 2 in the loaded state is collected as numerical data, the upper mold 100 is mounted on the lower surface (mold mounting surface) 12A of the mounting plate 12 of the correction unit 10 as shown in FIG. At the same time, the mounting plate 12 is moved downward by the operation of the clampers 13, 13..., And the mounting plate 12 is separated from the adjusters 20, 20.

  In this state, as shown in FIG. 12, the individual adjustment blocks 21, 21,... In each adjuster 20 of the correction unit 10 are moved downward by a predetermined dimension based on the numerical data collected in advance.

  Next, as shown in FIG. 13, the mounting plate 12 is moved upward by the operation of the clampers 13, 13..., And the mounting plate 12 is brought into pressure contact with the individual adjustment blocks 21, 21.

  In this way, when the slide 2 is deformed in a loaded state as shown in FIG. 14, the envelope surface connecting the lower end surfaces of the respective adjustment blocks 21, 21,... Exhibits an ideally shaped mold mounting surface. In addition, it is possible to prevent the upper mold 100 from being inadvertently deformed in a loaded state, and thus it is possible to suppress the defective accuracy of the pressed product and the damage of the mold as much as possible.

  As described above, according to the correction unit (die mounting position correction device) 10 in the above-described embodiment, the plurality of adjustment blocks 21, 21... Are individually moved to deform the mounting plate 12 into a desired shape. Thus, the displacement of the die mounting position accompanying the deformation of the press machine 1 can be easily corrected without using a shim, in other words, without requiring a complicated operation associated with the use of the shim.

  Further, according to the correction unit (die mounting position correcting device) 10 in the above-described embodiment, the upper die (die) 100 is attached to the lower surface (die mounting surface) 12A of the mounting plate 12 having a plate shape. Thus, it is possible to easily correct the displacement of the die attachment position accompanying the deformation of the press machine without being affected by the difference in the shape of the attachment surface in the die.

  That is, as described above, a large number of ribs 102, 102... Are formed on the upper surface (mounting surface) 100A of the upper mold (mold) 100, and the shapes of these ribs 102, 102. However, if the manufacturer is different, the shape of the mounting surface of the mold may be different, so when the mold mounting position correction device is configured to match the mold of a specific manufacturer, When the manufacturer's mold is used, a disadvantage that the displacement of the mold mounting position cannot be corrected occurs.

  On the other hand, in the correction unit (die mounting position correction device) 10 described above, since the mounting plate 12 is literally plate-shaped, the upper mold is independent of the shape of the ribs 102, 102. Since the entire upper surface (mounting surface) 100A of the (mold) 100 is supported by the lower surface (mold mounting surface) 12A of the mounting plate 12, deformation of the mounting plate 12 based on the operation of the adjusters 20, 20,. Therefore, the displacement is surely transmitted to the upper mold (mold) 100, and the displacement of the mold mounting position accompanying the deformation of the press machine is corrected without being affected by the difference in the shape of the mounting surface of the mold. It becomes possible.

  Incidentally, in the above-described embodiment, after the upper mold 100 is mounted on the slide 2 via the correction unit 10, the adjustment block 21 of the correction unit 10 is operated to correct the displacement of the mold mounting position. However, it is also possible to employ a work procedure in which the upper mold 100 is mounted on the correction unit 10 after the adjustment blocks 21, 21... Are operated in a predetermined manner.

  Here, by using the press machine equipped with the correction unit 10 described above, the machine difference between the press machine (mother machine) in the mold factory and the press machine in the production factory, that is, the same mold is used. Therefore, it is possible to eliminate the quality difference that occurs in products formed by different press machines.

  That is, while the correction unit is mounted on the slide of the press machine A in the mold factory, the displacement of the slide in the load state of the press machine B (without the correction unit mounted) in the production factory is measured and converted into data. Based on this measurement data When the upper die is attached to the press machine B by correcting the displacement of the die attachment position by the correction unit of the press machine A and correcting the shape of the upper die attached to the press machine A The quality can be reproduced without requiring any adjustment work.

  In the above-described embodiment, the operation of the adjustment blocks 21, 21,... In the correction unit 10 is collectively controlled by the controller based on the data measured in advance. After the upper mold 100 is mounted, the adjustment blocks 21, 21... Are individually operated by an operator's manual operation, and the operation of confirming the correction by trial strike is repeated, thereby correcting the displacement of the mold mounting position. Even when such a working mode is adopted, it is possible to correct the displacement of the mold mounting position much more efficiently than the adjustment work using the conventional shim. .

  In the above-described embodiment, the 40 adjusters (adjustment blocks) constituting the correction unit (die mounting position correction device) are laid out in a 4 × 10 lattice pattern. The number of adjustment blocks and the installation layout are not limited to the above-described embodiments, and can be set as appropriate based on various conditions such as the performance of the press machine and the specifications of the mold. Needless to say.

  In the above-described embodiment, the correction unit (die mounting position correction device) 10 including a plurality of adjusters 20 is attached to the lower surface 2a of the slide 2 as an attachment. It is also possible to directly incorporate the mold mounting position correcting device.

  FIG. 15 shows another embodiment of the present invention based on the above technical idea, and a plurality of adjusters 20 each having an adjustment block 21 'on a lower surface 2a' of a slide (mold support body) 2 '. ′, 20 ′... And a mounting plate 12 ′ are spaced from the slide 2 ′, and the mounting plate 12 ′ is supported by a plurality of clampers 13 ′, 13. The apparatus 10 'is constituted.

  Here, the configuration and operation mode of the mold mounting position correction device 10 'are basically the same as those of the correction unit (mold mounting position correction device) 10 described above. Omitted.

  In the mold mounting position correction apparatus 10 'as described above, as in the correction unit (mold mounting position correction apparatus) 10 described with reference to FIGS. Needless to say, the displacement of the die mounting position accompanying the deformation of the press machine can be easily corrected without being influenced by the shape of the rib on the die mounting surface.

  In the above-described embodiment, a wedge mechanism that moves the adjustment block by the cam action when the wedge block is advanced and retracted by the operation of the drive source is used as the driving means for moving the adjustment block. The wedge mechanism is limited to the wedge mechanism shown in the embodiment as long as it can move the adjustment block precisely and has a strength capable of reliably supporting the upper die (die) in a load state where pressure is applied. Without limitation, various drive mechanisms can be employed as the drive means.

  Further, in the above-described embodiment, an example in which the die mounting position correction device is attached to the slide (die support body) of the press machine is shown, but as described in the background art section, the breath machine is in a loaded state. In this case, since not only the slide but also the bolster can be deformed, a configuration in which the mold mounting position correcting device is attached to the bolster (mold support body) is also effective in canceling the deformation of the mold.

  In the above-described embodiment, the example in which the die mounting position correcting device according to the present invention is provided in the press machine for processing the metal sheet material is shown. Needless to say, the mold mounting position correcting apparatus according to the present invention can be applied to a press machine or the like for plastically deforming a sheet material to be formed into a desired shape.
