Description
Technical Field
[0001] The present application relates to the technical field of blanking presses, and specifically to a blanking mechanism of a blanking press. Background Art
[0002] A blanking press is a machine device that compresses powder or granular materials (such as metal powder, plastic particles, wood chips, etc.) into a certain shape.
[0003] When the blanking mechanism of the existing blanking press discharges materials after completing the blanking operation, its material discharge path and blanking path are shared, the blanking operation is relatively complex, not coherent enough, and the blanking operation efficiency is reduced. Utility Model Content
[0004] In view of the deficiencies of the prior art, the present application provides a blanking mechanism of a blanking press, which has the advantages of being able to continuously perform blanking operations, facilitating material discharge, and improving the blanking operation efficiency, and solves the problem that when the blanking mechanism of the existing blanking press discharges materials after completing the blanking operation, its material discharge path and blanking path are shared, the blanking operation is relatively complex, not coherent enough, and the blanking operation efficiency is reduced.
[0005] To achieve the above object, the present application provides the following technical solution: A blanking mechanism of a blanking press includes an operating table, a column is fixedly connected to the upper surface of the operating table, a blanking table is rotatably sleeved on the outer circumferential surface of the column, the bottom surface of the blanking table is in contact with the upper surface of the operating table, four equally spaced blanking grooves are opened inside the blanking table, a feeding device is provided on the upper surface of the operating table, a hydraulic cylinder is fixedly connected to the outer circumferential surface of the column, a pressing plate is provided on the bottom surface of the hydraulic cylinder, an electric push rod is fixedly connected to the outer circumferential surface of the column, a pushing plate is fixedly connected to the bottom surface of the electric push rod, a fixing rod is fixedly connected to the outer circumferential surface of the electric push rod, and a baffle is slidably connected inside the operating table.
[0006] Through the above solution, since when the blanking mechanism of the existing blanking press discharges materials after completing the blanking operation, its material discharge path and blanking path are shared, the blanking operation is relatively complex, not coherent enough, and the blanking operation efficiency is reduced. By driving the external gear ring to rotate through a gear, the blanking grooves on the blanking table can be rotated. By simultaneously driving the pushing plate and the fixing rod to move downward through the electric push rod, the baffle can be automatically opened during material discharge, so that the feeding and discharging operations can be carried out simultaneously, and the blanking operation can be carried out coherently, improving the blanking operation efficiency.
[0007] Further, a positioning ring is fixedly connected to the upper surface of the blanking table, and the inner wall of the positioning ring is rotatably sleeved with the column through a groove opened on the outer circumferential surface of the column.
[0008] Through the above solution, the blanking table is restricted to prevent the blanking table from lifting longitudinally, increasing the stability of the movement of the blanking table.
[0009] Furthermore, a motor is fixedly connected to the upper surface of the operating table. A gear is rotatably connected to the upper surface of the motor through an output shaft. An external tooth ring is fixedly sleeved on the outer circumferential surface of the pressing table, and the external tooth ring meshes with the gear.
[0010] Through the above solution, the gear can drive the pressing table to rotate under the action of the external tooth ring, so as to perform continuous and coherent pressing operations.
[0011] Furthermore, two sliding plates are fixedly connected to the outer surface of the baffle. The outer surface of each sliding plate is slidably connected to the operating table through an empty groove opened inside the operating table.
[0012] Through the above solution, the baffle is restricted to prevent it from sliding off, and the stability of the movement of the baffle is increased.
[0013] Furthermore, an inclined plate is fixedly connected to the upper surface of the baffle. The inclined plate is located directly below the fixed rod, and the upper surface of the inclined plate is an inclined surface.
[0014] Through the above solution, when the fixed rod moves downward, it can drive the baffle to move and open to one side through the inclined surface of the inclined plate, so as to perform the blanking operation.
[0015] Furthermore, a through hole is opened inside the baffle, and the through hole is located on one side of the inclined plate.
[0016] Through the above solution, the fixed rod can continuously move downward following the electric push rod, avoiding obstruction to the fixed rod.
[0017] Furthermore, a sliding rod is fixedly connected to the back surface of the baffle. The outer circumferential surface of the sliding rod is slidably inserted into the inside of the operating table. A fixed ring is fixedly sleeved on the outer circumferential surface of the sliding rod. A spring is fixedly connected to the front surface of the fixed ring, and the other end of the spring is fixedly connected to the back surface of the operating table.
[0018] Through the above solution, a reaction force is exerted on the baffle by virtue of the spring, so that the baffle can automatically move back.
[0019] Furthermore, a blanking channel is fixedly connected to the bottom surface of the operating table, and the blanking channel is located directly below the baffle.
[0020] Through the above solution, it is convenient for the material to slide down through the blanking channel, providing convenience for the staff.
[0021] Compared with the prior art, the technical solution of the present application has the following beneficial effects:
[0022] The blanking mechanism of this blanking press drives the external gear ring to rotate through a gear, causing the blanking groove on the blanking table to rotate. At the same time, the electric push rod drives the push plate and the fixed rod to move downward, enabling the baffle to automatically open during blanking. This achieves the effect that the loading and blanking operations can be carried out simultaneously, facilitating the blanking operation, and enabling continuous blanking operations, improving the efficiency of the blanking operation. It solves the problem that in the blanking mechanism of the existing blanking press, when discharging after the blanking operation, the discharging path and the blanking path share the same path, the blanking operation is relatively complex, not continuous, and reduces the efficiency of the blanking operation.

Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.
[0030] Please refer to Figure 1 , Figure 2 and Figure 3, A blanking mechanism of a blanking press in this embodiment includes an operating table 1. A column 2 is fixedly connected to the upper surface of the operating table 1. A blanking table 3 is rotatably sleeved on the outer circumferential surface of the column 2. The bottom surface of the blanking table 3 contacts the upper surface of the operating table 1. Four equally spaced blanking grooves 4 are opened inside the blanking table 3. A feeding device 6 is provided on the upper surface of the operating table 1. A hydraulic cylinder 7 is fixedly connected to the outer circumferential surface of the column 2. A pressing plate 8 is provided at the bottom surface of the hydraulic cylinder 7. An electric push rod 12 is fixedly connected to the outer circumferential surface of the column 2.

A baffle 15 is slidably connected inside the operating table 1.
[0031] Please refer to Figure 1 and Figure 3 , A positioning ring 5 is fixedly connected to the upper surface of the blanking table 3. The inner wall of the positioning ring 5 is rotatably sleeved with the column 2 through a groove opened on the outer circumferential surface of the column 2 to limit the blanking table 3 and prevent the blanking table 3 from lifting longitudinally, thereby increasing the stability of the movement of the blanking table 3.
[0032] Please refer to Figure 1 and Figure 3 , A motor 9 is fixedly connected to the upper surface of the operating table 1. A gear 10 is rotatably connected to the upper surface of the motor 9 through an output shaft. An external gear ring 11 is fixedly sleeved on the outer circumferential surface of the blanking table 3. The external gear ring 11 meshes with the gear 10, enabling the gear 10 to drive the blanking table 3 to rotate under the action of the external gear ring 11, and then performing continuous and coherent blanking operations.
[0033] Please refer to Figure 3 and Figure 4 , Two sliding plates 16 are fixedly connected to the outer surface of the baffle 15. The outer surface of each sliding plate 16 is slidably connected to the operating table 1 through an empty groove opened inside the operating table 1 to limit the baffle 15 and prevent the baffle 15 from sliding off, thereby increasing the stability of the movement of the baffle 15.
[0034] Please refer to Figure 3 and Figure 4 , An inclined plate 17 is fixedly connected to the upper surface of the baffle 15. The inclined plate 17 is located directly below the fixed rod 14. The upper surface of the inclined plate 17 is an inclined plane, enabling the fixed rod 14 to drive the baffle 15 to move and open to one side through the inclined plane of the inclined plate 17 when the fixed rod 14 moves downward, and then performing blanking operations.
[0035] Please refer to Figure 3 and Figure 4 , A through hole 18 is opened inside the baffle 15. The through hole 18 is located on one side of the inclined plate 17, enabling the fixed rod 14 to continuously move downward along with the electric push rod 12 and preventing any obstruction to the fixed rod 14.
[0036] Please refer to Figure 3 andFigure 4 On the back of the baffle 15, a slide bar 19 is fixedly connected. The outer circumferential surface of the slide bar 19 is slidably inserted into the interior of the operating table 1. A fixing ring 20 is fixedly sleeved on the outer circumferential surface of the slide bar 19. A spring 21 is fixedly connected to the front surface of the fixing ring 20, and the other end of the spring 21 is fixedly connected to the back surface of the operating table 1. By virtue of the reaction force exerted by the spring 21 on the baffle 15, the baffle 15 can be automatically retracted.
[0037] Please refer to Figure 1 、 Figure 2 and Figure 3 A blanking channel 22 is fixedly connected to the bottom surface of the operating table 1. The blanking channel 22 is located directly below the baffle 15, facilitating the sliding of materials from the blanking channel 22 and providing convenience for the staff.
[0038] In the pressing mechanism of a press in this embodiment, the outer tooth ring 11 is driven to rotate by the gear 10, so that the pressing groove 4 on the pressing table 3 can rotate. The electric push rod 12 drives the push plate 13 and the fixed rod 14 to move downward simultaneously, so that the baffle 15 can be automatically opened during blanking. It achieves the effect that the feeding and blanking operations can be carried out simultaneously, facilitating the blanking operation, and can also carry out the pressing operation coherently, improving the efficiency of the pressing operation. It solves the problem that in the pressing mechanism of the existing press, when discharging materials after completing the pressing operation, the discharging path and the pressing path share the same path, the pressing operation is relatively complex, not coherent enough, and the efficiency of the pressing operation is reduced.
[0039] It should be noted that the bottom end of the fixed rod 14 is of an arc surface structure to prevent the bottom end of the fixed rod 14 from scratching the inclined surface of the inclined plate 17 and causing damage to the inclined plate 17.
[0040] The working principle of the above embodiment is as follows: When a pressing operation is required, the materials are conveyed into the pressing groove 4 through the feeding device 6. Then, the motor 9 is started to drive the gear 10 to rotate through the output shaft. The gear 10 drives the pressing table 3 to rotate through the outer tooth ring 11, so that the pressing groove 4 filled with materials rotates to the lower part of the hydraulic cylinder 7. Then, the hydraulic cylinder 7 drives the pressing plate 8 to move downward for the pressing operation. During the forward movement of the pressing groove 4 filled with materials, the subsequent pressing groove 4 without materials will move to the lower part of the feeding device 6. At this time, the pressing and feeding operations can be carried out simultaneously. When blanking is required, the pressing groove 4 after pressing is rotated to the upper part of the baffle 15. Then, the electric push rod 12 is started to drive the push plate 13 and the fixed rod 14 to move downward simultaneously. During the downward movement of the fixed rod 14, the baffle 15 is driven to open to one side through the inclined plate 17. After the baffle 15 is opened, the push plate 13 will move into the pressing groove 4 and push the formed materials onto the lower blanking channel 22, and the materials will slide out to the outside through the blanking channel 22. When the fixed rod 14 retracts, the baffle 15 will automatically retract and close under the action of the spring 21.
