Description

Technical Field

[0001] The utility model relates to the technical field of fine forging protection, and particularly relates to a placing and protecting device for annular fine forgings. Background Art

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Annular forgings are products in the forging industry and are a type of forgings. Through heat treatment and forging processing of metal materials, the required annular shape and properties are obtained. Annular forgings are widely used in fields such as aerospace, ships, automobiles, and machinery.

[0003] When annular forgings are applied in the aerospace field, it is usually necessary to strictly control their overall quality. After the annular forgings are manufactured, they are finely processed on a lathe to meet the delivery standards (meeting the surface roughness and drawing size requirements). Usually, the placement methods of annular fine forgings stored in the warehouse are relatively chaotic, usually stacked or scattered. If the stacking height is too high, it is easy to cause the annular forgings to be unstable, resulting in scratches and bumps when they collide with each other, affecting the surface quality of the annular fine forgings and not meeting the needs of customers. Scattered placement also occupies the warehouse area and is not easy to manage uniformly. When the annular fine forgings are stored in the warehouse for a long time and the warehouse placement space is insufficient, the annular fine forgings are exposed to the air for a long time, and environmental factors such as rain may cause their surfaces to be corroded by corrosive substances in the air, thus polluting the annular forgings. For this reason, we propose a placing and protecting device for annular fine forgings. Summary of the Invention

[0004] Purpose of the Invention: To provide a placing and protecting device for annular fine forgings to protect the annular forgings.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1-6 , the present utility model provides a technical solution: a placement protection device for an annular forging, including a device box 1, a cover plate 2 rotatably installed on the top of the device box 1 and an opening 20 provided on the top of the device box 1. A rotating plate 4 is rotatably installed inside the device box 1. A rotary drum 6 is fixedly installed on the rotating plate 4. A plurality of guiding grooves 21 are provided on the inner wall of the rotary drum 6. Each guiding groove 21 is composed of a spiral area and a straight area. The end of the spiral area is connected to the middle section of the straight area, and the beginning of the spiral area is also connected to the beginning of the adjacent straight area. A guiding block 19 is fixedly installed at the connection of its first section. The upper end of the guiding block 19 is a right-angled surface, and its lower end is an inclined surface. A cylinder 5 is fixedly installed on the inner wall of the top of the device box 1. The rotary drum 6 is located directly below the cylinder 5. The output end of the cylinder 5 is fixedly installed with a fixing plate 17. A plurality of telescopic blocks 18 are installed on the fixing plate 17. A threaded shaft 16 is fixedly installed at the lower end of the fixing plate 17. When the control button 3 is pressed, the cylinder 5 works to push the fixing plate 17 and the telescopic blocks 18 downward. The right-angled surface of the guiding block 19 makes the telescopic blocks 18 enter the spiral area of the guiding groove 21, thereby driving the rotating plate 4 to rotate.

[0024] A number of trays 8 are provided on the rotating plate 4. A sleeve 7 is fixedly installed on each tray 8. A plurality of limiting rods 9 which are slidably connected to the trays 8 are fixedly installed on the rotating plate 4. A number of threaded rods 10 are rotatably installed on the rotating plate 4. The threaded rods 10 correspond to the sleeves 7 one by one and are located inside the sleeves 7 and are threadedly connected thereto. A large gear 12 is provided below the rotating plate 4. The large gear 12 is rotatably installed on the inner bottom wall of the device box 1. A threaded groove 15 which cooperates with the threaded shaft 16 is provided on the inner wall of the large gear 12. A small gear 13 which meshes with the large gear 12 is also rotatably installed on the inner bottom wall of the device box 1. A limiting groove 14 is provided on the small gear 13. A long block 11 is fixedly installed at the lower end of each threaded rod 10. The limiting groove 14 is located on the movement track of the long block 11. When the air cylinder 5 pushes the threaded shaft 16 downward, the threaded groove 15 on the large gear 12 is threadedly connected to the threaded shaft 16, pushing the large gear 12 to rotate, thereby driving the small gear 13 to rotate. At this time, the rotating plate 4 completes rotation. The next group of long blocks 11 are located in the limiting groove 14, and the long blocks 11 are limited by the limiting groove 14, so that the long blocks 11 drive the threaded rods 10 to rotate. The trays 8 are limited by the limiting rods 9, so that the trays 8 and the sleeves 7 move upward and rise to the outside of the device box 1 through the opening 20 at the top of the device box 1, facilitating the storage or sampling of the ring forgings.

[0025] When the loading and unloading are completed, the control button 3 is released, and the air cylinder 5 drives the threaded shaft 16 to rise, causing the large gear 12 to reverse, driving the small gear 13 and the threaded rod 10 to reverse, and the sleeve 7 and the tray 8 to descend. At the same time, the telescopic block 18 moves upward along the straight area in the guiding groove 21, and the inclined surface at the lower end of the guiding block 19 causes the telescopic block 18 to retract. When the fixing plate 17 is reset, the telescopic block 18 will pop out, effectively causing the rotating plate 4 to rotate in one direction. The rotation angle of the rotating plate 4 is controlled by the angle of the spiral area in the guiding groove 21. When the rotation is completed, the next group of trays 8 and sleeves 7 are located below the opening 20 at the top of the device box 1.

[0026] Specifically, when it is necessary to store or retrieve the ring forging, press the control button 3 to make the cylinder 5 work, push the fixed plate 17 and the telescopic block 18 downward. The right-angle surface of the guiding block 19 makes the telescopic block 18 enter the spiral area in the guiding groove 21, thereby driving the rotating plate 4 to rotate. When the rotation is completed, the next set of trays 8 and the sleeves 7 are located below the opening 20 at the top of the device box 1. Then, push the threaded shaft 16 downward. The threaded groove 15 on the large gear 12 is threadedly connected to the threaded shaft 16, pushing the large gear 12 to rotate, thereby driving the small gear 13 to rotate. At this time, the next set of long blocks 11 are located in the limiting grooves 14. The limiting grooves 14 limit the long blocks 11, causing the long blocks 11 to drive the threaded rods 10 to rotate. The limiting rods 9 limit the trays 8, causing the trays 8 and the sleeves 7 to move upward and rise out of the device box 1 through the opening 20 at the top of the device box 1. When the loading and unloading are completed, release the control button 3. The cylinder 5 drives the threaded shaft 16 to rise, causing the large gear 12 to reverse, driving the small gear 13 and the threaded rods 10 to reverse. The sleeves 7 and the trays 8 move downward. At the same time, the telescopic block 18 moves upward along the straight area in the guiding groove 21. The inclined surface of the guiding block 19 causes the telescopic block 18 to retract. When the fixed plate 17 is reset, the telescopic block 18 will pop out.
