Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

Fig. 1 is a side view of the present invention. Fig. 2 is a front view of the present invention. As shown in fig. 1 and 2, the bending machine includes a deflection compensation structure in which the bending machine is mounted on a table column 1. The deflection-compensated structure comprises a wedge structure and a support table 2 for supporting the wedge structure. The upper die holder 3 can move downwards relative to the workbench upright post 1 to bend the workpiece placed on the lower die holder 7.

The support platform 2 is fixed on the workbench upright post 1. Specifically, the support table 2 has a chute-like structure having a concave cross section. The wedge structure is installed in the sliding groove of the support platform 2.

The ramp structure comprises an upper slide 6 and a lower slide 5 which are movable in relation to each other in a tiltable manner. The upper slide block 6 is fixed at the bottom of a lower die holder 7 of the bending machine. Specifically, the contact surfaces of the upper slide 6 and the lower die holder 7 are fixed together by a fixing pin 9. The lower slide block 5 is fixed on the support platform 2 of the inclined iron structure. Fig. 4 is an enlarged schematic view of a portion B in fig. 2. As shown in fig. 4, the support base 2 has a slide groove 4 in a side wall thereof. The side wall of the lower sliding block 5 is provided with a fixing hole with a thread on the inner wall. The fixing bolt 8 passes through the sliding groove 4 and is screwed into the fixing hole of the lower slider 5 to fix the lower slider 5 to the support table 2. When the fixing bolt 8 is not screwed, the lower slider 5 can slide along the concave-shaped sliding groove of the support platform 2, and the moving range of the fixing hole does not exceed the range of the sliding groove 4 in the sliding process. When the lower slider 5 slides to a proper position, the fixing bolt 8 passes through the sliding groove 4 and is screwed into the fixing hole, and the lower slider 5 and the support table 2 are fixed together.

As shown in fig. 4, the bottom surface of the upper slider 6 includes a first inclined surface. The top surface of the lower slider 5 includes a second inclined surface. The first inclined surface and the second inclined surface have the same inclination and opposite inclination directions. After the upper slide block 6 and the lower slide block 5 are installed, the first inclined surface and the second inclined surface are attached together. When the lower slider 5 slides in the negative direction of the x-axis shown in fig. 4, the second inclined surface moves in the positive direction of the x-axis, and the upper slider 6 moves in the positive direction of the y-axis while maintaining its position in the direction of the x-axis. When the lower slider 5 slides in the positive x-axis direction shown in fig. 4, the second inclined surface moves in the positive x-axis direction, and the upper slider 6 moves in the negative y-axis direction.

Further, as shown in fig. 2, a plurality of wedge structures are placed on the support table 2. The relative positions of the upper slide 6 and the lower slide 5 are the same or different in a plurality of ramp structures. When the relative positions of the upper slider 6 and the lower slider 5 are different, the height of the upper slider 6 is also different. The upper slide 6 near the middle of the support platform 2 is higher, and the upper slide 6 far from the middle of the support platform 2 is lower, so that the lower die base 7 is supported into an arch shape with a high middle and two low sides to resist flexibility. Further, a plurality of the wedge structures are arranged at equal intervals, so that accurate adjustment is facilitated.

The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made without departing from the basic structure of the invention.
