Description

Technical Field

[0001] This utility model relates to the field of stamping technology for mechanical parts, and in particular to a stamping die. Background Technology

[0002] In the field of mechanical parts stamping technology, stamping dies are the core equipment for achieving mass production and efficient forming of parts. Their core function is to complete the stamping forming of mechanical parts through the closing action of the upper and lower dies, making them an indispensable key equipment in this field.

[0003] In existing stamping dies, a flipping method is often used to unload the formed parts inside the lower die for easier material unloading. However, this type of structure has the following shortcomings in practical applications: Firstly, the support shaft of the flipping mechanism is frequently subjected to pressure due to long-term stamping loads and flipping stresses, which can easily cause deformation, resulting in deviations in the actual position of the lower die. This leads to insufficient forming accuracy of mechanical parts and a reduced product qualification rate. Secondly, during the flipping unloading process, when the die is in a vertical position, the formed parts are prone to slipping out of the lower die prematurely due to a lack of effective constraints, making the unloading process difficult to control. For thinner mechanical parts, when they fall sideways, they are prone to scraping against the conveyor belt, which may not only damage the parts but also scratch the conveyor belt, affecting the stable operation of the equipment. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art where the support shaft of the flipping mechanism is easily deformed, resulting in deviation of the lower die, insufficient precision of the subsequently formed parts, and the formed parts easily slip out prematurely during flipping and unloading, causing thin parts to scrape against the conveyor belt and affecting the operation of the equipment. Therefore, a stamping die is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stamping die includes a stamping table with a through hole inside. A first motor is mounted on the outer surface of the stamping table, and a rotating shaft is fixedly connected to the output end of the first motor. The rotating shaft passes through the stamping table and is rotatably connected to the inner wall of the through hole. A rotating block is fixedly connected to the outer surface of the rotating shaft, and a lower die is fixedly connected to the upper surface of the rotating block. An upper die is provided above the stamping table, and a blocking mechanism is provided outside the lower die. A reinforcing mechanism is provided below the stamping table, and a conveyor belt is provided below the stamping table. Two leg supports are mounted on the bottom surface of the stamping table.

[0007] Preferably, a support frame is fixedly connected to the upper surface of the stamping table, a first electric push rod is installed inside the support frame, and the upper surface of the upper mold is fixedly connected to the output end of the first electric push rod.

[0008] Preferably, the shielding mechanism includes an extension plate, the outer surface of which is fixedly connected to the lower mold, a second motor is mounted on the bottom surface of the extension plate, a connecting rod is fixedly connected to the output end of the second motor, and a baffle plate is fixedly connected to the outer surface of the connecting rod.

[0009] Preferably, the reinforcing mechanism includes a reinforcing plate, the upper surface of which is in contact with the stamping table and the flipping block.

[0010] Preferably, the outer surface of the reinforcing plate is slidably connected to two guide support plates, and the upper surfaces of the two guide support plates are fixedly connected to the bottom surface of the stamping table.

[0011] Preferably, the reinforcing mechanism further includes a mounting plate, the outer surface of which is fixedly connected to two guide support plates, and a second electric push rod is mounted on the outer surface of the mounting plate, the output end of which is fixedly connected to the reinforcing plate.

[0012] Preferably, the outer surface of the mounting plate is fixedly connected to two reinforcing strips, and one end of each of the two reinforcing strips is fixedly connected to the outer surface of the stamping table.

[0013] Compared with the prior art, the present invention provides a stamping die, which has the following beneficial effects:

[0014] This invention effectively solves the problem of drive shaft deformation when stamping mechanical parts using a flip-over blanking die by setting up a reinforcing mechanism and a shielding mechanism. The reinforcing plate moves along the guide support plate to the bottom of the stamping table and the flipping block under the drive of the second electric push rod, distributing the load to avoid deformation of the flipping shaft and ensuring the positional accuracy of the lower die. In addition, during the flip-over blanking, the second motor drives the connecting rod to constrain the forming part with the baffle plate, preventing premature slippage and avoiding side contact and scraping of thin mechanical parts with the conveyor belt.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A stamping die includes a stamping table 1, the stamping table 1 having a through hole 2 inside, the through hole 2 providing space for flipping.

[0023] A first motor 3 is installed on the outer surface of the stamping table 1. The output end of the first motor 3 is fixedly connected to a rotating shaft 4. The first motor 3 provides driving force to the rotating shaft 4 to achieve stable rotation.

[0024] The flipping shaft 4 passes through the stamping table 1 and is rotatably connected to the inner wall of the through hole 2. The outer surface of the flipping shaft 4 is fixedly connected to the flipping block 5, and the upper surface of the flipping block 5 is fixedly connected to the lower mold 6. The flipping shaft 4 and the flipping block 5 are linked together, so that the lower mold 6 can be flipped.

[0025] An upper die 9 is provided above the stamping table 1. A support frame 7 is fixedly connected to the upper surface of the stamping table 1. A first electric push rod 8 is installed inside the support frame 7. The support frame 7 provides rigid support for the first electric push rod 8 to ensure stamping stability.

[0026] The upper surface of the upper mold 9 is fixedly connected to the output end of the first electric push rod 8. The lower mold 6 is provided with a blocking mechanism, which includes an extension plate 10. The first electric push rod 8 drives the upper mold 9 to rise and fall, thereby realizing the mold closing and opening actions.

[0027] The outer surface of the expansion plate 10 is fixedly connected to the lower mold 6. The bottom surface of the expansion plate 10 is equipped with a second motor 11. The expansion plate 10 provides an installation carrier for the second motor 11. The structure layout is reasonable. When setting it up, the front and rear lengths of the through hole 2 should be controlled to avoid the expansion plate 10 from colliding with the side wall of the through hole 2.

[0028] The output end of the second motor 11 is fixedly connected to a connecting rod 12, and a baffle plate 13 is fixedly connected to the outer surface of the connecting rod 12. The baffle plate 13 can be rotated and adjusted to achieve anti-drop constraint of the molded part and prevent the molded part from sliding out prematurely when flipping and unloading.

[0029] A reinforcing mechanism is provided below the stamping table 1. The reinforcing mechanism includes a reinforcing plate 16. The upper surface of the reinforcing plate 16 is in contact with the stamping table 1 and the flipping block 5. Two guide support plates 17 are slidably connected to the outer surface of the reinforcing plate 16. The reinforcing plate 16 shares the load and prevents the flipping shaft 4 from being subjected to excessive pressure deformation.

[0030] The upper surfaces of the two guide support plates 17 are fixedly connected to the bottom surface of the stamping table 1. The reinforcing mechanism also includes a mounting plate 18. The outer surface of the mounting plate 18 is fixedly connected to the two guide support plates 17. The guide support plates 17 guide the reinforcing plates 16 to slide, ensuring accurate movement trajectory and providing support.

[0031] A second electric push rod 14 is installed on the outer surface of the mounting plate 18. The output end of the second electric push rod 14 is fixedly connected to the reinforcing plate 16. Two reinforcing strips 19 are fixedly connected to the outer surface of the mounting plate 18. The second electric push rod 14 drives the reinforcing plate 16 to move, realizing the switching between support and avoidance.

[0032] One end of each of the two reinforcing strips 19 is fixedly connected to the outer surface of the stamping table 1. A conveyor belt 20 is provided below the stamping table 1. Two leg support plates 15 are installed on the bottom surface of the stamping table 1. The reinforcing strips 19 enhance the strength of the mounting plate 18 and improve the overall structural stability.

[0033] Working principle: The lower mold 6 is horizontally positioned above the through hole 2 of the stamping table 1 via the flipping block 5. The baffle plate 13 is in the open position in the initial state of the second motor 11, without obstructing the opening of the lower mold 6. The reinforcing plate 16 extends along the guide support plate 17 to the lower part of the stamping table 1 and the flipping block 5 under the initial drive of the second electric push rod 14, providing support for the flipping block 5. The upper mold 9 is located directly above the lower mold 6 in the initial state of the first electric push rod 8, maintaining a distance from the lower mold 6. The leg support plate 15 supports the stamping table 1 to maintain horizontal stability, and the conveyor belt 20 is in the waiting state.

[0034] The blank to be stamped is placed in the lower mold 6 to complete the loading. The first electric push rod 8 installed on the support frame 7 is activated. The output end of the first electric push rod 8 extends downward, driving the upper mold 9 to move vertically downward until the upper mold 9 and the lower mold 6 close, applying pressure to the blank to complete the stamping. During this process, the reinforcing plate 16 provides rigid support to the stamping table 1 and the flipping block 5 through the guide support plate 17, preventing the flipping shaft 4 from deforming due to concentrated force. After stamping is completed, the first electric push rod 8 drives the upper mold 9 to return to its original position and disengage from the lower mold 6. Subsequently, the second electric push rod 14 is activated, and its output end retracts, driving the reinforcing plate 16 to slide away from the stamping table 1 along the guide support plate 17 until it is completely disengaged from under the stamping table 1 and the flipping block 5, releasing the support to avoid interfering with subsequent flipping actions.

[0035] The second motor 11 installed on the extension plate 10 is started. The output end of the second motor 11 drives the connecting rod 12 to rotate, causing the baffle plate 13 to rotate around the connecting rod 12 to the opening side of the lower mold 6, forming a lateral shield for the molded part and preventing the molded part from slipping off prematurely during the rotation process. The first motor 3 on the outer surface of the stamping table 1 is started. The output end of the first motor 3 drives the rotating shaft 4 to rotate. The rotating shaft 4 passes through the stamping table 1 and drives the rotating block 5 and the lower mold 6 to rotate synchronously around the rotating shaft 4 until the opening of the lower mold 6 faces downward. At this time, the second motor 11 is started again, driving the baffle plate 13 to rotate in the opposite direction and reset, releasing the shield for the molded part. Under the action of gravity, the molded part is taken out from the lower mold 6 and falls flat onto the conveyor belt 20 below, and is transported to the next process by the conveyor belt 20.

[0036] After the material is unloaded, the first motor 3 drives the flipping shaft 4 to rotate in the opposite direction, causing the flipping block 5 and the lower mold 6 to flip and reset to a horizontal state; the second electric push rod 14 drives the reinforcing plate 16 to reset to the bottom of the stamping table 1 and the flipping block 5 to form support again, and the equipment returns to its initial state, waiting for the next stamping cycle.

[0037] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
