[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 5 The utility model provides an embodiment: a bending workbench mold adjustment structure, including a workbench 1, with legs 16 vertically welded at the four corners of its bottom end to ensure the overall stability, and an empty slot is opened in the middle, and a lower mold 14 is installed inside through a rotating mechanism, which can be conveniently adjusted to the corresponding lower mold 14 according to the needs of bending, and then the workpiece can be bent, and an upper mold 5 is installed on the workbench 1 through a lifting assembly, which can be adapted to the lower mold 14 to perform bending processing on the workpiece, and its lifting assembly includes a hydraulic telescopic rod 2 symmetrically installed on the workbench 1, and a lifting plate 3 is installed at the output end of the hydraulic telescopic rod 2, and a mounting plate 4 can be welded under the lifting plate 3. The mounting plate 4 and the upper mold 5 can be fixedly connected by bolts to ensure stability and firmness during use.

[0023] See also Figure 1-Figure 5In order to facilitate the rotation and adjustment of the lower mold 14 to meet the needs of different bending angles and ensure stability after adjustment, prevent rotation during the bending process, and ensure the quality of processing, a rotating rod 12 of a rotating mechanism is provided inside the empty slot, and a connecting piece 15 (the number can be four groups) can be welded on its peripheral side surface, and the lower mold 14 is fixedly installed with bolts (when the lower mold 14 is horizontal, it is slightly lower than the workbench 1, and the rotation adjustment does not affect the workpiece. At the same time, it can also cooperate with the upper mold 5 to complete the bending operation when the operation is completed). The lower mold 14 can be the same lower mold 14, which can be used as a spare, or it can be of different depths, which is convenient for bending the workpiece at different angles. It is a relatively mature technology. I will not go into details here, and one end of the rotating rod 12 passes through the empty slot and extends to the outside and is fixedly connected to the output end of the motor 6 through a coupling, which can be easily carried for rotation adjustment. In order to be able to position and fix after rotation adjustment, two groups of L-shaped plates 21 of the positioning mechanism are symmetrically welded at the bottom end of the workbench 1 (located at both ends of the empty slot), and a movable plate 19 is installed on it through two groups of second electric push rods 20. The positioning column 17 of the limiting component is welded in the middle of the top of the movable plate 19, and a rubber sleeve 18 is provided on the outside. Positioning holes 13 are opened at corresponding positions at both ends of the rotating rod 12. There are two groups of positioning holes 13 at the same end, and they are perpendicular to each other, which is convenient for positioning and fixing the lower mold 14 after rotation adjustment by plugging in the positioning column 17 to ensure stability.

[0024] See also Figure 1-Figure 5 In order to facilitate the pushing of the workpiece and thus facilitate the bending operation at different positions, a connecting plate 7 is welded to the middle part of one side of the workbench 1, on which a vertical plate 8 of the pushing mechanism is vertically welded, and two groups of first electric push rods 9 are symmetrically installed on the side walls of the vertical plate 8. The output ends of the first electric push rods 9 are jointly installed with a push plate 10, which can facilitate the pushing operation of the workpiece. In order to avoid hard contact, a gasket 11 is adhered to the side wall of the push plate 10 away from the first electric push rod 9.

[0025] Working principle: When the utility model is in use, the corresponding lower mold 14 is determined according to the bending needs, and the motor 6 rotates, which drives the rotating rod 12 to rotate, and then the corresponding lower mold 14 on the connecting piece 15 can be rotated to the workbench 1. After the rotation is completed, the second electric push rod 20 is extended, and the movable plate 19 is moved upward, and then the positioning column 17 is inserted into the positioning hole 13, and the rotating rod 12 can be positioned and fixed with the rubber sleeve 18. Then, the workpiece to be bent is placed on the workbench 1, and the hydraulic telescopic rod 2 is contracted, which drives the lifting plate 3 to move downward, and then the upper mold 5 cooperates with the lower mold 14 to complete the bending operation. The hydraulic telescopic rod 2 is moved up and reset, and then the lower mold 14 is adjusted according to the bending needs. If adjustment is needed, the second electric push rod 20 is contracted to move the positioning column 17 out of the positioning hole 13, and the limit of the rotating rod 12 is lost. The rotation adjustment operation can be completed by the operation of the motor 6. Repeat the above steps to position and fix the rotating rod 12, and then extend the first electric push rod 9 to move the push plate 10, and then cooperate with the gasket 11 to push the workpiece to the downward bending position. The next bending operation can be completed by the upper mold 5 and the lower mold 14, and then the processing of the workpiece can be completed.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
