Description

Technical Field

[0001] The utility model relates to the technical field of bending moulds, in particular to a bending mould deflection compensation adjustment structure. Background Art

[0002] Deflection is the linear displacement of the axis of the rod in a direction perpendicular to the axis or the linear displacement of the mid-surface of the plate shell in a direction perpendicular to the mid-surface when subjected to force or non-uniform temperature changes. When the bending machine processes the workpiece, it will be affected by multiple factors such as the rigidity of the fuselage, the weight of the workpiece, the processing pressure and the selection of the tool, resulting in the deflection of the fuselage. Once the fuselage deflects, it will affect the processing accuracy and workpiece quality; among them, the size and shape of the deflection are related to the material, size, wall thickness, radius of curvature and bending angle of the workpiece.

[0003] In order to reduce the influence of deflection on the machining accuracy of workpieces, most of the existing bending dies use mechanical compensation to compensate for deflection. The existing folding knife die deflection compensation mainly uses hexagon socket flat-end set screws to connect the tool holder, and performs positive adjustment during the connection process. However, due to the large screw pitch, it is difficult to control the size during fine adjustment. In addition, when the die is directly connected to the tool holder with hexagon socket flat-end set screws, the contact surface is small, and a gap will be caused between the die and the tool holder when the die is adjusted, which makes the screws at risk of loosening, thereby causing structural instability and affecting the deflection compensation effect.

[0004] Referring to the patent publication number "CN209222931U", the patent name "A longitudinal mechanical deflection compensation device for a bending machine worktable", the technical scheme discloses "A longitudinal mechanical deflection compensation device for a bending machine worktable, belonging to the technical field of bending machines. It includes an upper inclined plate and a lower inclined plate, both of which are integral structures and have consistent sizes, wherein the lower surface of the upper inclined plate is provided with a first longitudinal inclined surface, and the slope of the first inclined surface decreases from a larger slope Kj to a smaller slope Ki from the middle to both ends, and the two adjacent first inclined surfaces are connected by an arc surface, and the curvature of the arc surface increases from a smaller curvature Ri to a larger curvature Rj from the middle to both ends; the upper surface of the lower inclined plate is provided with a second inclined surface corresponding to the first inclined surface. The upper inclined plate and the lower inclined plate of the device are both integral structures and have consistent sizes, so that the movement consistency of the lower inclined plate is high, and the cumulative error can be eliminated or offset to ensure the accuracy of bending forming". Although the technical scheme can realize deflection compensation adjustment, the technical scheme cannot effectively ensure the stability of the contact surface, resulting in unstable adjustment structure.

[0005] Therefore, how to achieve bending mold deflection compensation is the main technical problem that technicians need to solve. Utility Model Content

[0044] Embodiment 1

[0045] In order to ensure the surface contact between the bending template 2 and the movable tool holder 1 when the bending template 2 is subjected to deflection compensation, increase the force stability, and reduce the gap, in this embodiment: by movably installing the bending template 2 on the outside of the movable tool holder 1, and then installing the adjustment component 3 in the installation groove 11, the adjustment component 3 includes a movable wedge block 31 and a lifting journal, one side of the movable wedge block is fitted with one side of the bending template 2, and the other side of the movable wedge block 31 is set as an inclined surface, and the other side of the movable wedge block 31 is abutted against the lifting wedge block 32. When adjusting the position of the lifting wedge block 32, the movable wedge block 31 can be driven by the lifting wedge block 32, and then the bending template 2 can be pressed against one side of the movable wedge block 31. Since a plurality of installation grooves 11 are provided, and a plurality of installation grooves 11 correspond to the bending template 2, it can be ensured that a plurality of movable wedge blocks 31 can press against the bending template 2 for deflection compensation.

[0046] It should be noted that, in order to ensure uniform force, several installation grooves 11 are evenly distributed on the movable tool holder 1, and openings are provided on the outside of several installation grooves 11, so that several openings face the bending template 2, so that several movable wedge blocks 31 can be pressed against the bending template 2 to improve the deflection compensation effect.

[0047] It should also be noted that, in order to facilitate the installation of the adjustment component 3 inside the installation groove 11 and to make the openings of several installation grooves 11 flush with the outside of the movable knife seat 1, several installation grooves 11 can be arranged in a rectangular structure as a whole, so that the adjustment component 3 is adapted to the installation groove 11, effectively preventing the adjustment component 3 from being too loose.

[0048] It should be noted that in order to realize the movably installation of the bending template 2 on the outside of the movable tool holder 1, a plurality of mounting through holes 21 are provided on the outside of the bending template 2, and a plurality of fixing through holes 12 are provided on the outside of the movable tool holder 1, and the plurality of mounting through holes 21 are aligned one by one with the plurality of fixing through holes 12, and connecting bolts 22 are provided inside the mounting through holes 21, so that the mounting through holes 21 can be connected to the fixing through holes 12 by the connecting bolts 22, thereby ensuring that the bending template 2 is easy to install or disassemble, and the bending template 2 can also be limited by the connecting bolts 22.

[0049] In response to the above, a further supplementary explanation is that, in order to ensure that a number of mounting through holes 21 are connected to a number of fixed through holes 12, the number of mounting through holes 21 can be evenly distributed along the length direction of the bending template 2, ensuring that the bending template 2 can be evenly stressed after being installed on the outside of the movable tool holder 1.

[0050] Embodiment 2

[0051] In order to adjust the lifting wedge block 32 and drive the movable wedge block 31 to compensate for the deflection of the bending template 2 through the lifting wedge block 32, and keep the force on the lifting wedge block 32 and the movable wedge block 31 stable, in this embodiment: an adjusting screw hole 321 and a limiting screw hole 322 are respectively opened on the surface of the lifting wedge block 32, two adjusting screw holes 321 are provided, and adjusting bolts 323 are provided inside the two adjusting screw holes 321, and adjusting top screws 324 are provided inside the limiting screw holes 322. The two adjusting screw holes 321 are symmetrically arranged on both sides of the outside of the lifting wedge block 32, so that the end of the adjusting bolt 323 abuts against the inner wall of the mounting groove 11, and the adjusting screw 323 can be twisted to adjust the position of the adjusting screw 323. The bolt 323 is used to adjust the installation height of the lifting wedge block 32 inside the installation groove 11. During adjustment, the lifting wedge block 32 drives the movable wedge block 31 to move. Since the other side of the movable wedge block 31 is tilted downward, and the other side of the movable wedge block 31 is in contact with the outside of the lifting wedge block 32, when the lifting wedge block 32 descends, the movable wedge block 31 moves toward the position of the bending template 2 until one side of the movable wedge block 31 is pressed against the bending template 2 to perform deflection compensation. One side of the movable wedge block 31 is in contact with one side of the bending template 2, thereby achieving surface-to-surface contact, increasing the force-bearing area while ensuring a smooth connection, and reducing the gap between the bending template 2 and the movable tool holder 1.
