Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, the present invention proposes a kind of bender, it comprises frame 1, be located at the first gripper shoe 5 in frame 1, be located at two the second gripper shoes 6 in the first gripper shoe 5, each second gripper shoe 6 is equipped with a nip roll 3, a pressing plate 7 is provided with between described two nip rolls 3, the top of described pressing plate 7 is provided with the pressure head 2 be connected with press, when pressure head 2 moves downward, pressing plate 7 can be propped up move downwards, make the workpiece bending be placed on above pressing plate 7, described first gripper shoe 5 is provided with multiple first kidney slot 5.1, described each second gripper shoe 6 is provided with multiple second kidney slot 6.1, described each second gripper shoe 6 is connected in the first gripper shoe 5 by bolt through the first kidney slot 5.1 and the second kidney slot 6.1, the length direction of described first kidney slot 5.1 is vertical with the length direction of the second kidney slot 6.1.Described pressing plate 7 is connected in the first gripper shoe 5 by cylinder or hydraulic cylinder, can move downward under the pressing of pressure head relative to the first gripper shoe, and when pressure head resets, due to hydraulic pressure or air pressure, pressing plate also resets.
Operation principle is, workpiece is put on the pressing plate between two nip rolls, controlling press makes pressure head move downward, and pressure head withstands pressing plate and moves downward, because nip roll blocks both sides, just make the workpiece bending on pressing plate, in the present invention, the position of two nip rolls can be adjusted by the position adjusting two the second gripper shoes, so just can adapt to the workpiece of different size, and the bending operation that bending parameter is different, so just do not need to change Bending Mould.
After adopting said structure, when the workpiece of bending different size, unclamp bolt, the position of two the second gripper shoes can be adjusted by the first kidney slot and the second kidney slot, can adjust arbitrarily in planar range, adjust to applicable position, and then tight a bolt, the position adjusting the second gripper shoe can adjust the distance between two nip rolls, to adapt to different bending parameters, so, when the workpiece that bending is different, only need the position of the second gripper shoe adjusting bender, and then change bending parameter, do not need more mold exchange and bending mechanism, the versatility of bender is very high, also greatly production cost is saved.
Described first gripper shoe 5 is provided with six the first kidney slots 5.1, described each second gripper shoe 6 is provided with three the second kidney slots 6.1, and the second kidney slot 6.1 in described each second gripper shoe 6 is corresponding with the position of the first kidney slot 5.1 in the first gripper shoe 5 respectively.The second kidney slot in described second gripper shoe can make the second gripper shoe adjust position on the length direction of the second kidney slot, the first kidney slot in described first gripper shoe can make the second gripper shoe adjust position on the length direction of the first kidney slot, the length direction of the first kidney slot is vertical with the length direction of the second kidney slot, then the second gripper shoe can adjust position arbitrarily in the plane relative to the first gripper shoe.Because three points determine a plane, therefore each second gripper shoe is provided with three the second kidney slots is that structure is the simplest, really the most stable selection.
Fig. 3, Figure 4 shows that the first gripper shoe of bender and the structural representation of the second gripper shoe, as shown in the figure, second gripper shoe is bolted in the first gripper shoe, each second gripper shoe is equipped with three the second kidney slots, first gripper shoe is provided with six the first kidney slots, when the second gripper shoe is assemblied in the first gripper shoe, bolt can be fixed through the optional position of the first kidney slot and the second kidney slot, and the position of such second gripper shoe in the first gripper shoe just can be adjusted by elasticity bolt.
Described bender also comprises a working plate 4, and the top that described working plate 4 is located at nip roll 3 is connected in the second gripper shoe 6, and the dual-side of described working plate 4 is respectively equipped with multiple locating hole 4.1.Because workpiece is placed on pressing plate to carry out bending, rock on pressing plate for preventing workpiece, therefore above nip roll, working plate is established, workpiece is positioned on working plate by the locating hole on working plate, so just can prevent the skew of workpiece in the process of bending, working plate is provided with multiple locating hole, the workpiece of different size can be adapted to.
Working plate is located on bender, its position is higher than nip roll, can be concordant with pressing plate, operationally, workpiece can be placed on working plate, positioned by the locating hole on working plate, when carrying out bending operation, workpiece can not offset, and owing to being provided with location, the position of bending is very accurate, facilitates operative.During location, being generally fabrication hole workpiece is also provided with for locating, by bolt or other device, the fabrication hole on workpiece and the locating hole on working plate being linked together, just can complete location.
In a preferred embodiment, the first gripper shoe is provided with symmetrical scale label perpendicular to the both sides, axis on the second gripper shoe moving direction, thus is convenient to record second gripper shoe mobile location information.
In another preferred embodiment, as Fig. 6, one of them of two nip rolls comprises upper and lower two parts, and these two parts are arranged between two blocks of plectanes of side.These two parts at least outer circumference portion are made up of elastomeric material, therefore have good skid resistance.Upper and lower two parts present arc-shaped towards the part of workpiece.Preferably, the summit of lower part and the highest summit of another nip roll are everywhere on same level line.Aforementioned plectane top has chute setting up and down, and the core shaft end of upper part can slide in chute, and therefore upper part can move up and down towards lower part, and thus upper and lower two parts can close to each otherly press together, and also can be separated from each other.Wherein chute as shown in Figure 7, has a lock part bottom chute, and the core shaft end of described upper part may be locked in the lock part of chute, and now upper part is tightly resisted against on the bottom of nip roll.Two blocks of plectanes are articulated on the support that is connected in the second gripper shoe.Like this, deposit in case not having working plate, locating hole and other extra clamping devices, when carrying out bending workpieces, first by workpiece through the nip roll with upper and lower two parts, move down the first half of described nip roll and the core shaft end of upper part to be slided in described lock part thus to carry out clamping work pieces, the nip roll in Forging Process with upper and lower two parts can rotate with the warpage of workpiece.After completion of processing, the core shaft end of upper part is discharged from lock part, now can take out the workpiece processed.Preferably, described chute has multiple lock part from top to bottom, is therefore applicable to the workpiece of different-thickness.
