Description

Technical Field

[0001] This utility model relates to the field of automated stamping equipment technology, and more specifically, to a small stamping line rotary feeding device. Background Technology

[0002] In modern industrial production, stamping is an important forming process that is widely used in many fields such as automobiles, electronics, and home appliances. For small stamping lines, efficient and precise feeding operations are the key to ensuring production efficiency and product quality.

[0003] In traditional stamping processes, manual or single mechanical feeding is often required. After each stamping is completed, the material needs to be repositioned and placed, resulting in a single feeding being able to meet the stamping requirements for only one time. The overall process is cumbersome and inefficient.

[0004] A search revealed that Chinese patent CN109013956A discloses a rotary stamping feeding device. This structure uses a controller to extend a cylinder, causing an electromagnet mounted on the cylinder to contact the steel plate to be stamped. The controller controls the electromagnet's magnetism, causing it to attract the steel plate. Then, the controller rotates a motor, which in turn rotates a turntable. The rotated turntable satisfies the stamping requirements of the steel plate attracted by two adjacent magnets on a support rod. A spring is provided at one end of the cylinder to prevent the steel plate from becoming rigidly connected to the magnets during stamping, thus preventing the steel plate from detaching or deforming. Multiple support rods are evenly distributed on the turntable. This device has a simple structure, is easy to use, and can achieve multiple stamping operations with a single feeding, effectively improving work efficiency and reducing labor costs.

[0005] However, in actual use, this structure uses electromagnets to attract steel plates. Although it can achieve material feeding, relying solely on electromagnet attraction makes it difficult to guarantee the positional stability of the material during rotation and stamping. This cannot meet the requirements for material positioning accuracy in automated production, and can easily lead to deviations in subsequent stamping processes, reducing production efficiency and product qualification rate.

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a small stamping line rotary feeding device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A small stamping line rotary feeding device includes a base, a fixed frame and a support seat are fixedly provided on the top of the base, the support seat is provided on one side of the fixed frame, and a positioning mechanism is provided on the top of the base.

[0009] The positioning mechanism includes a rotating worktable set on the top of the base. The surface of the rotating worktable is provided with several placement slots in a ring shape.

[0014] An outer support ring is fixedly installed at the top of the fixed frame, and an inner T-shaped support ring is rotatably installed inside the outer support ring. One end of the inner T-shaped support ring is connected to the bottom of the rotary table.

[0015] By adopting the above technical solution: the stepper motor drives the rotating rod through gear transmission to achieve precise rotation of the rotary table, meeting the needs of automated feeding; the ball bearing and the inner and outer support rings cooperate to ensure smooth rotation and improve operational stability.

[0017] The surface of the feeding frame is provided with a discharge port, a guide plate is fixedly installed inside the feeding frame, and an inclined discharge frame is fixedly installed on one side of the discharge port of the feeding frame.

[0018] By adopting the above technical solution: the hopper, together with the inclined plate, can realize the automatic sliding of materials, the guide plate in the feeding frame guides the orderly movement of materials, and accurately conveys them to the rotary table through the discharge port and the inclined discharge frame, thereby realizing automated feeding and reducing manual intervention.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] 1.

[0021] 2. By setting up a rotary feeding mechanism, compared with existing technologies, the heat dissipation holes on the surface of the fixed frame can dissipate heat for power components such as stepper motors, avoiding continuous operation and overheating that could affect lifespan and stability, and ensuring long-term stable operation of the equipment. Moreover, the meshing transmission between the first gear ring and the second gear ring, together with the rotating rod supported by ball bearings, achieves precise transmission of rotational motion, ensuring feeding accuracy. In addition, the cooperation between the inner T-shaped support ring and the outer support ring provides additional support for the rotary worktable, ensuring smooth rotation and meeting the stability requirements of automated equipment. Continuous feeding is achieved through cyclic rotation, improving production efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The embodiments disclosed in this application are as follows: Figure 1-5 The small stamping line rotary feeding device shown includes a base 1, a fixed frame 2 and a support 3 fixedly installed on the top of the base 1, the support 3 is installed on one side of the fixed frame 2, and a positioning mechanism is installed on the top of the base 1.

[0030] The positioning mechanism includes a rotating worktable 4 set on the top of the base 1. The surface of the rotating worktable 4 is provided with several placement slots 5 in a ring shape. An L-shaped fixing plate 6 is fixedly set on one side of the placement slot 5 at the top of the rotating worktable 4. Multiple small electric telescopic rods 7 are fixedly installed inside the L-shaped fixing plate 6. A positioning plate 8 is fixedly set at the output end of the small electric telescopic rods 7. A rubber layer 9 is fixedly set at one end of the positioning plate 8.

[0031] A guide block 10 is fixedly installed on one side of the positioning plate 8, and multiple guide grooves 11 are opened on the surface of the L-shaped fixing plate 6. The guide block 10 is slidably connected to the guide grooves 11.

[0032] When the material enters the placement trough 5, the small electric telescopic rod 7 inside the L-shaped fixing plate 6 is activated, and its output end pushes the positioning plate 8 to move in the direction of the material. During this process, the guide block 10 slides along the guide groove 11 to ensure that the positioning plate 8 moves smoothly until the rubber layer 9 at one end of the positioning plate 8 contacts the material, thereby clamping and positioning the material to prevent the material from shifting during subsequent rotation.

[0033] Reference Figure 2-4As shown, a rotary feeding mechanism is provided inside the base 1. The rotary feeding mechanism includes a stepper motor 12 fixedly installed inside the fixed frame 2. A rotating shaft 13 is fixedly provided at the output end of the stepper motor 12. A first gear ring 14 is fixedly provided on the surface of the rotating shaft 13. A second gear ring 15 is meshed on the surface of the first gear ring 14. A rotating rod 16 is fixedly provided inside the second gear ring 15.

[0034] One end of the rotating rod 16 passes through the fixed frame 2 and is fixedly connected to the bottom of the rotating worktable 4. The rotating rod 16 and the fixed frame 2 are connected by ball bearings. Multiple heat dissipation holes are provided on the surface of the fixed frame 2.

[0035] An outer support ring 17 is fixedly installed on the top of the fixed frame 2, and an inner T-shaped support ring 18 is rotatably installed inside the outer support ring 17. One end of the inner T-shaped support ring 18 is connected to the bottom of the rotary worktable 4.

[0036] After positioning is completed, the stepper motor 12 inside the fixed frame 2 starts, and its output end drives the rotating shaft 13 to rotate. The heat dissipation holes on the surface of the fixed frame 2 dissipate heat for the internal stepper motor 12 and other power components, preventing the life and stability from being affected by the continuous operation and temperature rise. The first gear ring 14 on the surface of the rotating shaft 13 rotates accordingly. Since the first gear ring 14 meshes with the second gear ring 15, the second gear ring 15 drives the rotating rod 16 to rotate synchronously.

[0037] Moreover, the rotating rod 16 rotates stably under the support of the ball bearing, thereby driving the rotating worktable 4 fixedly connected to it to rotate. At the same time, the inner T-shaped support ring 18 rotates synchronously within the outer support ring 17, providing additional support for the rotating worktable 4 and ensuring its rotation process is smooth.

[0038] After the rotary worktable 4 rotates to the set angle, the stepper motor 12 stops working. At this time, the placement slot 5 containing the material moves to the stamping processing position to wait for the subsequent stamping operation, while the empty placement slot 5 rotates to the discharge end of the inclined discharge frame 24 to receive the next batch of material. This cycle repeats to achieve continuous feeding.

[0039] Reference Figure 4-5 As shown, a feeding frame 19 is fixedly installed on the top of the support base 3, and a hopper 20 is provided through the top of the feeding frame 19. An inclined plate 21 is fixedly installed on the inner wall of the hopper 20.

[0040] The surface of the feeding frame 19 is provided with a discharge port 22, the inside of the feeding frame 19 is fixedly provided with a guide plate 23, and an inclined discharge frame 24 is fixedly provided on one side of the discharge port 22 of the feeding frame 19.

[0041] The operator puts the material to be processed into the hopper 20. The inclined plate 21 on the inner wall of the hopper 20 guides the material to slide down to the next level structure. The material enters the feeding frame 19 along the inclined plate 21.

[0042] The material entering the feeding frame 19 moves along the guide plate 23 inside the feeding frame 19 under its own gravity, and finally slides out from the discharge port 22, and is transported to the placement slot 5 of the rotary worktable 4 through the inclined discharge frame 24.

[0043] Working principle of this utility model:

[0044] This utility model is a small stamping line rotary feeding device. When the device is in use, the operator puts the material to be processed into the hopper 20. The inclined plate 21 on the inner wall of the hopper 20 guides the material to slide down to the next level structure. The material enters the feeding frame 19 along the inclined plate 21.

[0045] The material entering the feeding frame 19 moves along the guide plate 23 inside the feeding frame 19 under its own gravity, and finally slides out from the discharge port 22, and is conveyed to the placement slot 5 of the rotary worktable 4 through the inclined discharge frame 24.

[0046] When the material enters the placement slot 5, the small electric telescopic rod 7 inside the L-shaped fixing plate 6 is activated, and its output end pushes the positioning plate 8 to move towards the material. During this process, the guide block 10 slides along the guide groove 11 to ensure that the positioning plate 8 moves smoothly until the rubber layer 9 at one end of the positioning plate 8 contacts the material, thereby clamping and positioning the material to prevent the material from shifting during subsequent rotation.

[0047] After positioning is completed, the stepper motor 12 inside the fixed frame 2 starts, and its output end drives the rotating shaft 13 to rotate. The heat dissipation holes on the surface of the fixed frame 2 dissipate heat for the internal stepper motor 12 and other power components, preventing the life and stability from being affected by the continuous operation and temperature rise. The first gear ring 14 on the surface of the rotating shaft 13 rotates accordingly. Since the first gear ring 14 meshes with the second gear ring 15, the second gear ring 15 drives the rotating rod 16 to rotate synchronously.

[0048] Moreover, the rotating rod 16 rotates stably under the support of the ball bearing, thereby driving the rotating worktable 4 fixedly connected to it to rotate. At the same time, the inner T-shaped support ring 18 rotates synchronously within the outer support ring 17, providing additional support for the rotating worktable 4 and ensuring its rotation process is smooth.

[0049] After the rotary worktable 4 rotates to the set angle, the stepper motor 12 stops working. At this time, the placement slot 5 containing the material moves to the stamping processing position to wait for the subsequent stamping operation, while the empty placement slot 5 rotates to the discharge end of the inclined discharge frame 24 to receive the next batch of material. This cycle repeats to achieve continuous feeding.

[0050] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
