Description

Technical Field

[0001] The utility model relates to the technical field of a material supporting mechanism, in particular to a numerical control machining auxiliary material supporting mechanism. Background Technique

[0002] Numerical control bending machine machining is a kind of numerical control machining. When a sheet metal is subjected to the extrusion force of the bending machine, it will be turned up to form the required bending angle. When performing numerical control bending machining on the sheet metal, some sheet metals are relatively long and cannot be placed stably on the lower die of the bending machine. It is necessary to use a material supporting mechanism to support the sheet metal to increase the stability of the sheet metal when it is bent and placed.

[0003] For example, the authorized patent with the publication number of CN 212551130 U (a front material supporting device for a numerical control bending machine): includes an installation bracket and a flipping mechanism.

[0023] Please refer to Figures 1-4 , an embodiment provided by the present invention: a numerical control machining auxiliary material supporting mechanism, including a bottom box 1, a top box 2 is arranged above the bottom box 1, a bottom plate 4 is rotatably installed above the top box 2, a support plate 3 is arranged above the bottom plate 4, the support plate 3 includes a fixed plate 301, a movable strip 302 and a connecting strip 303, the fixed plate 301 is fixedly connected to the bottom plate 4 by screws, a long slot 3011 is arranged inside the fixed plate 301, and three long slots 3011 are arranged, three movable strips 302 are arranged, the three movable strips 302 are respectively arranged inside the three long slots 3011, the connecting strip 303 is arranged on one side of the fixed plate 301, and the three movable strips 302 are all fixedly connected to the connecting strip 303.

[0024] During use, when numerically controlled bending processing of long-sized plates, the movable strip 302 can be driven to move out of the long slot 3011 of the fixed plate 301, so that the overall length of the support plate 3 is increased, which is convenient for lifting and supporting the rear end of the long-sized plate away from the bending machine, and increases the stability of the plate during bending.

[0025] Further, a threaded cavity 3021 is arranged inside the middle movable strip 302, a first threaded rod 9 is arranged inside the threaded cavity 3021, the first threaded rod 9 is threadedly connected to the movable strip 302, one end of the first threaded rod 9 extends to the outside of the movable strip 302 and is rotatably connected to the fixed plate 301, a first handwheel 10 is arranged on one side of the fixed plate 301, and the first handwheel 10 is fixedly connected to the first threaded rod 9, so that by rotating the first handwheel 10, the first threaded rod 9 can be driven to rotate, which is convenient for driving the movable strip 302 to move.

[0026] Further, a second handwheel 11 is arranged on one side of the front end and the rear end of the fixed plate 301, fixing screws are fixedly installed inside the two second handwheels 11, one end of the fixing screw far away from the second handwheel 11 is threadedly connected to the fixed plate 301 and extends into the long slot 3011 to contact the movable strip 302, and then after the position of the movable strip 302 is adjusted, the position of the movable strip 302 can be fixed by screwing the fixing screw of the second handwheel 11.

[0027] Furthermore, a support vertical plate 12 is fixedly installed inside the top box 2. The upper end of the support vertical plate 12 is in close contact with the bottom plate 4, capable of supporting the bottom plate 4. A second hydraulic cylinder 13 is arranged inside the top box 2. The lower end of the second hydraulic cylinder 13 is hinged to the top box 2, and the piston rod end of the second hydraulic cylinder 13 is hinged to the bottom plate 4.

[0028] Furthermore, a first hydraulic cylinder 5 is fixedly installed above the middle inside the bottom box 1. A pump oil device for the first hydraulic cylinder 5 is arranged inside the bottom box 1.

[0030] Furthermore, four corners below the bottom box 1 are fixedly installed with universal wheels 8, increasing the convenience of moving the material supporting mechanism.

[0031] Working principle: When in use, move the lifting mechanism in front of the CNC bending machine. Drive the top box 2 to move up and down through the hydraulic cylinder 1 5 for height adjustment. When performing CNC bending processing on the plate, one end of the plate far from the CNC bending machine can fall on the support plate 3 for lifting and support, increasing the stability of the plate. During the bending process of the plate, the hydraulic cylinder 2 13 can drive the bottom plate 4 to rotate, enabling the bottom plate 4 to provide support during the bending process of the plate. At the same time, when performing CNC bending processing on long-sized plates, the fixing screw can be loosened by turning the handwheel 2 11, and then the threaded rod 1 9 can be rotated by turning the handwheel 1 10, so that the movable strip plate 302 moves out of the long slot hole 3011 of the fixing plate 301, thereby increasing the overall length of the support plate 3, facilitating the lifting and support of the rear end of the long-sized plate far from the bending machine, and increasing the stability of the plate during bending.
