Description

Technical Field

[0001] This utility model relates to the field of material turning machine technology, specifically to a pneumatic automatic material turning mechanism. Background Technology

[0002] In sheet metal shearing, the non-sheared edges of the remaining material often need to be trimmed. This requires flipping the remaining material before trimming. Currently, the market relies on manual labor and auxiliary tools for flipping or rotating the sheet metal, which is labor-intensive, inefficient, and poses safety hazards; it also fails to automate the operation of the equipment. Therefore, this invention provides a pneumatic automatic flipping mechanism to solve the above-mentioned technical problems. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, the purpose of this utility model is to provide a pneumatic automatic material turning mechanism to solve the problems of high labor intensity, low production efficiency, and safety hazards associated with manual material turning in existing sheet metal shearing processes.

[0004] This utility model is achieved through the following technical solution:

[0005] A pneumatic automatic material turning mechanism includes two left turning arms, a left synchronous shaft, a left bearing seat, two parallel support seats, a right bearing seat, a right synchronous shaft, two right turning arms, and a drive mechanism. The support seats are mounted on the machine body. Symmetrically arranged left and right bearing seats are provided on both support seats. A left synchronous shaft is mounted on each of the two left bearing seats, and a right synchronous shaft is mounted on each of the two right bearing seats. A left turning arm is fixedly mounted at each end of the left synchronous shaft, and a right turning arm is fixedly mounted at each end of the right synchronous shaft. The left and right turning arms are symmetrically arranged about the support seats. The same drive mechanism is mounted on both the left and right synchronous shafts. A stopper is provided on the end of each left turning arm near the left synchronous shaft, and a stopper is symmetrically provided on the end of each pair of right turning arms near the right synchronous shaft.

[0006] Preferably, the drive mechanism includes a swing arm, a drive cylinder, and a hinge support. Swing arms are fixed to both ends of the left synchronous shaft and both ends of the right synchronous shaft. The other end of each swing arm is hinged to the extension end of the drive cylinder. The cylinder body of the drive cylinder is hinged to the hinge support, which is mounted on the machine body. When the extension action of the drive cylinder's extension arm causes the left and right tilting arms to clamp the sheet metal, the sheet metal tilts towards the right tilting arm.

[0007] Preferably, the length of the right flip arm is not less than the length of the left flip arm.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This invention achieves the flipping action of sheet metal by controlling the left and right flipping arms with a drive cylinder and a swing arm.

[0015] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings. Figure 1-3A pneumatic automatic material turning mechanism is shown, comprising two left turning arms 2, a left synchronous shaft 4, a left bearing seat 5, two parallel support seats 9, a right bearing seat 10, a right synchronous shaft 11, two right turning arms 12, and a drive mechanism. The support seats 9 are mounted on the machine body. Symmetrically arranged left bearing seats 5 and right bearing seats 10 are provided on each of the two support seats 9. The left synchronous shaft 4 is mounted on the two left bearing seats 5, and the right synchronous shaft 11 is mounted on the two right bearing seats 10. A left synchronous shaft 11 is fixedly mounted at each end of the left synchronous shaft 4. The flipping arm 2 has a right flipping arm 12 fixedly mounted at each end of the right synchronous shaft 11. The left flipping arm 2 and the right flipping arm 12 are symmetrically arranged about the support base 9. The left synchronous shaft 4 and the right synchronous shaft 11 are both equipped with the same drive mechanism. The left flipping arm 2 has a stopper 3 at the end near the left synchronous shaft 4, and the corresponding right flipping arm 12 has a stopper 3 symmetrically arranged at the end near the right synchronous shaft 11. To prevent interference between parts, the stoppers 3 on each pair of left flipping arms 2 and right flipping arms 12 are staggered. The flipping action of the sheet metal is achieved by controlling the left flipping arm 2 and the right flipping arm 12 to flip using the drive cylinder 7 and the swing arm 6. The stopper 3 ensures that the sheet metal does not fall during the flipping process, thus replacing manual flipping, improving production efficiency, and eliminating the safety hazards of manual operation.

[0017] As one embodiment of this utility model, such as Figure 1 The drive mechanism includes a swing arm 6, a drive cylinder 7, and a hinge support 8. Swing arms 6 are fixed to both ends of the left synchronous shaft 4 and both ends of the right synchronous shaft 11. The other end of each swing arm 6 is hinged to the extension / retraction end of the drive cylinder 7. The cylinder body of the drive cylinder 7 is hinged to the hinge support 8, which is mounted on the machine body. When the extension / retraction of the drive cylinder 7 causes the left tilting arm 2 and the right tilting arm 12 to clamp the sheet metal 1, the sheet metal 1 tilts towards the right tilting arm 12. This can be achieved by setting a fixed angle between the swing arm 6 and its corresponding tilting arm; the technical principle is simple and will not be elaborated further here.

[0018] It is worth mentioning that the aforementioned drive cylinder 7 can also be replaced with a servo electric cylinder, electric push rod, electro-hydraulic push rod, or pneumatic cylinder, as long as it can achieve the telescopic function, there are no restrictions on this.

[0019] To prevent sheet metal 1 from tilting and falling onto the right flipping arm 12 due to its own weight, and then falling off the right flipping arm 12 when it is flipped to a horizontal position because it is too long, the length of the right flipping arm 12 is set to be no less than the length of the left flipping arm 2. In this way, if sheet metal 1 does not fall off when it is initially placed on the left flipping arm 2, it will not fall off the right flipping arm 12.

[0020] The working principle of this utility model:

[0021] See Figure 1 ,2 3. This utility model has two support seats 9, one in front and one in back. In particular, symmetrically arranged left and right bearing seats are provided on both support seats 9. A left synchronous shaft 4 is installed on the two left bearing seats 5, and a right synchronous shaft 11 is installed on the two right bearing seats 10. A left tilting arm 2 is installed at each end of the left synchronous shaft 4, and a right tilting arm 12 is installed at each end of the right synchronous shaft 11. The left tilting arms 2 and right tilting arms 12 are symmetrically arranged. A stopper 3 is installed on the end of each tilting arm near the synchronous shaft. A drive mechanism is installed on each of the two synchronous shafts. The drive mechanism includes a swing arm 6 connected to the synchronous shaft. A drive cylinder 7 is hinged to the outer end of the swing arm 6. The tail end of the drive cylinder 7 is mounted on the foundation through a hinge support 8. The sheet metal 1 is placed on the left tilting arm 2, and then the hydraulic cylinder 7 is activated. Its telescopic end extends, driving the swing arm 6 and further driving the synchronous shaft fixedly connected to the swing arm 6. Thus, the left synchronous shaft 4 and the right synchronous shaft 11 begin to tilt, and the left tilting arm 2 and the right tilting arm 12 tilt accordingly until they clamp the sheet metal 1. The stopper 3 blocks the sheet metal 1 to prevent it from sliding down, and the sheet metal 1 tilts towards the right tilting arm 12. Then, the telescopic end of the hydraulic cylinder 7 retracts, and the sheet metal 1 tilts and falls onto the right tilting arm 12 due to its own weight, thus flipping the sheet metal 1. Finally, the left tilting arm 2 and the right tilting arm 12 return to their original horizontal positions.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
