Being used for when sheet material is carried out bending of the application has from Fig. 1 and the obvious visible anvil tool of Fig. 2 by means of the device that a bent-strip and crooked die are regulated the boundary that moves both vertically of crooked forging die in the zone at the bottom of the die.The last forging die of working with anvil tool forms with routine techniques, and it does not further illustrate in the drawings.Anvil tool has a die 1, and die 1 is equipped with a pod 2.The rib 3 of two sides and the following end 4, constitute the border of pod 2.Adjustable end 4, constitute according to the application's the device surface by baffle plate 5, and the one side of baffle plate 5 drops on several bearing pins 6, and these bearing pins are inserted in the hole of corresponding configuration arranged side by side of die 1 die body.The upper surface supporting baffle 5 of bearing pin 6, the one side of baffle plate 5 constitute at the bottom of adjustable die 4.

Die 1 is fixed on the die bearing 7 by strutbeam 8.By means of the fixing strutbeam 8 of horizontal fishbolt 9, but bolt 9 is disposing with distributing and is pressing to one of strutbeam 8 rib 11 of extension vertically downward along strutbeam 8 under the effect of the hose arrangement 10 that a pneumatic type loads.This hose arrangement 10 is arranged in U type hollow 12, with screw rod 13 ducted body 12 is fixed on the die bearing 7.

The lower end 14 of bearing pin 6 is stretched out downwards from the hole of die 1 and is positioned on the strutbeam 15.This strutbeam 15 is in the cavity of die bearing 7, and this cavity constitutes the continuous part of pod 2 and at the longitudinal extension of die 1.Strutbeam 15 can vertically be installed between the corresponding guide surface 16 of die bearing 7 movably.Be used for doing a Wedge device that moves both vertically and form, and can regulate by a total device by three wedge idols 17,18 and 19.

Figure 3 illustrates wedge idol 17, this wedge idol goes up wedge 17a by one and a following wedge 17b is assembled into.Last wedge 17a be so fixing, to be that it can not carry out vertically moving, but in height is adjustable.Regulate for carrying out height, following wedge 17b will be moved.Go up wedge 17a formation cavity when wedge 17b moves instantly relatively and become room 20, this cavity or room 20 have disadvantageous effect for the accuracy of buckling work, because in the deformation operation process, during wedge 17a high load capacity, local buckling can appear in cavity or 20 zone, position.For avoiding this point, will use a plurality of wedge idols, use 3 wedge idols according to embodiment, these wedge idols dispose and are unified into a Wedge device side by side.17, the 18 and 19 such placements arranged side by side of three wedge idols, face wedge at each wedge idol place when promptly wedge moves instantly and form room 20,21 and 22, these rooms are not corresponding to each other, but vertically offseting relative to each other, this configuration is clearly visible especially from Fig. 4, and this figure has expressed three wedge idols 17,18,19 briefly.Here, wedge idol 17 has room 20, and the wedge idol 18 of adjacency has 21, the three the wedge idols in room and then is provided with room 22.This device is such, and promptly room 20,21 and 22 vertically is being offset toward each other.The room 20,21,22 of configuration will never be consistent continuously can to accomplish three thus.As room 20,21,22 laterally is being break-through, and then this will mean structural a kind of important weakening, because under big rock deformation pressure, wedge will bend, and this can cause the inaccuracy of processing.

From Fig. 2 obviously as seen, the last wedge 16a of wedge idol 16 is fixed by means of the anchor clamps 23 that can vertically move, thereby make instantly wedge 16b when the direction of arrow moves, last wedge 16a is in height rather than vertically is being conditioned that this moment, anchor clamps 23 slided in the corresponding guider of die position 24.A pressing piece 25 is housed in die position 24, and this pressing piece 25 can and act on the strutbeam 15 by pneumatic loading or hydraulic loaded, and the lower end of bearing pin 6 is supported on the strutbeam 15.

From Fig. 2, can further find out, dwindling of bearing pin the upper end have baffle plate 5, this baffle plate 5 in the vertical suitably again the segmentation.

A kind of possible device that is used for regulating down wedge from Fig. 5 obviously as seen.Precondition is that following wedge 17b, 18b and 19b and 22 are not consistent.Following wedge 17b has a connecting cleat 26, and this connecting cleat 26 is connected with a nut 28 that can move on round guide rail 27.Nut 28 and a guide pad 29 fit together, and this guide pad 29 is installed on the adjusting nut 30.When axle 31 rotations, this adjusting nut is reciprocating.Axle 31 is bearing in the body 32 and by drive motors 33 and drives.The transparent cover plate of parts 32 is represented with label 34.

Can see further that from Fig. 56 of bearing pins are on the surface of strutbeam 15.Fig. 5 shows pressing piece 25 equally and is pressed on the strutbeam 15 facing to last wedge 17a.From Fig. 5, be easy to learn, adjusting by nut 30 can make guide pad 29 move on round guide rail 27, like this, by means of clamping plate 26 can make down wedge 17b and on entity 17b, 18b and 19b move, be equally last wedge 17a, the 18a of coadunation and 19a therefore and in height adjusted.

Sheet material to be out of shape be placed in die body above, handle bottom land be in the position for carrying out bending simultaneously, 4 determine predetermined angle with support edges 3 at the bottom of this position, this predetermined angle conforms to the specified angle that will reach.By depressing of bending die, make sheet material press to bottom land, the previously described angle regulator of packing into simultaneously.Each angle can be accurately determined and be kept in height adjusting by bearing pin 6.Described Wedge device is used for the vertical adjusting of described bearing pin 6, and this Wedge device has last wedge and the corresponding wedge down that becomes to stack and also can move jointly, and wedge also is that formation is stacked up and down.The height and position that keeps sheet material accurately to regulate can be realized simply.By means of can be under the adjusting nut 30 that moves on the axle 31 be regulated wedge, can improve the precision of the vertical adjusting of bottom once more.

It should be noted that also above-mentioned whole manipulation process can realize automatically by preprogram, also can use a kind of numerical control simultaneously and handle.
