Description

Technical Field

[0001] The utility model relates to the technical field of numerical control blanking machines, in particular to a material turning structure for numerical control blanking machines. Background Art

[0002] CNC blanking machine is a mechanical device that cuts materials by computer-controlled cutting tools according to preset programs and instructions. It can automatically complete the cutting, grooving, punching and other processes of materials such as plates and metal pipes. CNC blanking machine has the characteristics of high precision, high efficiency and high degree of automation, and is widely used in furniture manufacturing, architectural decoration, automobile manufacturing and other industries.

[0003] When some existing CNC blanking machines process plates, some plates need to be grooved or punched on both sides. When the plates need to be turned over, the staff needs to release the fixing components of the plates. Since the materials are in contact with the work surface, the staff needs to lift the materials first, and then turn the plates over manually. After turning the plates over, the plates are fixed and positioned again by the fixing components. This operation step is relatively complicated and requires more time of the staff. At the same time, when turning over heavier plates, it may require the cooperation of multiple staff members, which is time-consuming and labor-intensive, resulting in reduced processing efficiency of the materials, affecting the normal processing of the materials, and having low practicality and flexibility. In view of this, we propose a material turning structure for CNC blanking machines to solve the above problems. Utility Model Content

The staff places the plate material to be processed on the upper part of the load-bearing plate 13, and then fixes the material through the clamping assembly. The material is subsequently processed by the punching assembly 4. When the material needs to be turned over, the L-shaped connecting plate 5 is moved. When the L-shaped connecting plate 5 moves to the front side of the load-bearing plate 13, it continues to move. The movement of the L-shaped connecting plate 5 drives the movement of the driving assembly. The movement of the driving assembly will drive the first threaded rod 9 to rotate. The rotation of the first threaded rod 9 drives the horizontal plate 10 to slide inside the limiting groove 8, and the movement of the horizontal plate 10 drives the vertical plate 1 1, the movement of the vertical plate 11 drives the load-bearing plate 13 to slide inside the groove 12, thereby increasing the space under the material, and subsequently starting the first motor 27 to drive the electric telescopic rod 23 on the left to rotate, and the rotation of the electric telescopic rod 23 drives the rotation of the clamping assembly, and finally the material is turned over.

When the tooth plate 17 and the gear 15 are in contact, the tooth plate 17 and the gear 15 are meshed, so the tooth plate 17 drives the gear 15 to rotate, and the rotation of the rotating shaft 14 can be driven by the rotation of the gear 15.

[0030] Furthermore, a first pulley 18 is sleeved on the outer surface of the rotating shaft 14, and a second pulley 19 is sleeved on the outer surface of one end of the first threaded rod 9 located inside the cavity 6.

The upper clamping plate 26 is slidably connected to the interior of the sliding groove 24 and is threadedly sleeved on the outer surface of the second threaded rod 25. The staff places the material between the transverse plate of the L-shaped clamping plate 22 and the upper clamping plate 26, and then rotates the second threaded rod 25 to drive the movement of the upper clamping plate 26, thereby finally achieving the clamping of the plate material.

[0033] The device automatically lowers the load-bearing plate 13 by moving the L-shaped connecting plate 5, and then starts the first motor 27 to enable the clamping assembly to flip the plate material. This saves the worker's physical strength and does not require the worker to perform secondary fixation, thereby reducing the worker's operating steps and improving the worker's work efficiency.

[0034] Working principle:

[0035] When the material turning structure of the CNC blanking machine is in use, the staff places the plate material to be processed on the upper part of the load-bearing plate 13, and then fixes the material through the clamping assembly, and then processes the material through the punching assembly 4. When the material needs to be turned over, the L-shaped connecting plate 5 is moved. When the L-shaped connecting plate 5 moves to the front side of the load-bearing plate 13, it continues to move. The movement of the L-shaped connecting plate 5 drives the movement of the driving assembly, and the movement of the driving assembly will drive the first threaded rod 9 to rotate. The rotation of the first threaded rod 9 drives the horizontal plate 10 to slide inside the limiting groove 8, and the movement of the horizontal plate 10 drives the vertical plate 11 to move. The movement of the vertical plate 11 drives the load-bearing plate 13 to slide inside the groove 12, thereby increasing the space under the material. Subsequently, the first motor 27 is started to drive the electric telescopic rod 23 on the left to rotate, and the rotation of the electric telescopic rod 23 drives the rotation of the clamping assembly, so as to finally realize the turning of the material.
