Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically to a metal stamping equipment and a stamping die. Background Technology

[0002] Stamping equipment is an important piece of equipment used in metal processing. It applies pressure to cause plastic deformation of metal materials, thereby obtaining parts of the required shape and size. The most common stamping equipment is the stamping die. The stamping die can process metal materials into parts or semi-finished products. Because the stamping die has the characteristic of forming in one stamping, it has become one of the more common stamping equipment.

[0003] In the process of using traditional stamping equipment, the main demolding method is to eject the formed part from the die by air pressure or mechanical ejector pins. However, the demolding process by air pressure or mechanical ejector pins can easily cause damage and wear to the stamped parts.

[0004] To solve the above problems, stamping equipment that can avoid damaging the stamped parts is needed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a metal stamping equipment and stamping die, which solves the problem that traditional demolding methods, which rely on air pressure or mechanical ejectors to push the formed part out of the die, can easily cause damage and wear to the stamped part.

The inner wall of the gear is provided with a circular groove on one side of the plurality of damping springs, and a limiting ball is engaged with the inner wall of each circular groove.

[0009] Furthermore, the gas delivery mechanism includes two L-shaped push rods fixedly installed on the top surface of the fixed base plate. The arms of the two L-shaped push rods are slidably mounted with storage cylinders for storing gas, and the surfaces of the two storage cylinders are fixedly connected to the surface of the half-body mold. A piston block for pushing gas is fixedly installed at one end of the two L-shaped push rods near the half-body mold.

[0015] A metal stamping equipment includes the metal stamping die described in any of the above embodiments.

[0016] Compared with the prior art, the present invention provides a metal stamping equipment and stamping die, which has the following beneficial effects:

[0017] 1. The device adopts the mold opening and closing method, which can prevent damage and wear to the stamped parts during demolding. The device can also blow air on the stamped parts through the air blowing effect generated by the extrusion pressure during the mold opening process. The air blowing effect can also clean the inside of the mold, avoiding the impact of debris or impurities in the mold on the surface of the stamped parts.

[0018] This device utilizes U-shaped slots and U-shaped blocks to ensure better fit between the two half-die dies, and the fit is tighter during the process, avoiding problems that affect the processing quality of the stamped parts. The trapezoidal cross-section of the U-shaped blocks can better ensure the docking effect of the two half-die dies.

[0019] The device utilizes the S-shaped design of the inner wall of the moving trough plate to ensure that the rotating wheel and crank block are pushed and squeezed by the inclined surface of the S-shaped inner wall during rotation, thus ensuring the basic movement effect of the moving trough plate. By using the same diameter for the limiting ball and the storage tank, it can ensure that when the force between the fixed ring and the gear is large, the limiting ball can retract into the storage tank.

[0020] The device utilizes a support ring and an L-shaped support block to ensure the stability of the storage cylinder during operation, avoid shaking during operation, and increase the stability of the internal structure. The inclined design of the air outlet allows for better cleaning of the semi-die cavity and also helps to push the stamped part away from the semi-die cavity more effectively.

[0040] The working principle of the above embodiments is as follows:

[0041] Before using the device, the electric telescopic rod 9 is fixed to other main structures to ensure the pushing effect of the electric telescopic rod 9. The method of fixing the electric telescopic rod 9 to other main structures is an existing mature fixing method. This application will not elaborate too much on the existing mature technologies and mature fixing methods.

[0042] When using the device, the stamping material is placed on the two half-die 6. Before stamping the material, the two half-die 6 are in a relatively tight-fitting state, which can ensure a tight fit with the punch 3 and ensure the processing quality of the stamped part. During the processing, the punch 3 moves downward. As the punch 3 moves, it will drive the vertical tooth plate 10 to move downward. Due to the S-shaped inner wall of the moving groove plate 701, when the vertical tooth plate 10 moves downward, it will drive the gear 710 to rotate counterclockwise in the front view direction of the device. In this way, the gear 710 will have a tendency to drive the longitudinal rod 705 to move counterclockwise through the fixed ring 709. Thus, the longitudinal rod 705 passes through the crank block 707. The rotating wheel 708 will press against the lower inner wall of the moving groove plate 701, which will cause the left and right moving groove plates 701 to move relative to each other. This will make the half-die 6 fixed on the moving groove plate 701 press more tightly and firmly. However, due to the continuous descent of the vertical tooth plate 10, the two half-die 6 are tightly fitted but will not be displaced. At this time, the downward pressing force will be greater than the clamping force of the damping spring 712 in the fixed ring 709 pressing the limiting ball 714 and the circular groove 713. This will cause the gear 710 to disengage from the fixed ring 709. This will not affect the normal processing of the stamping part, nor will it affect the normal meshing transmission of the vertical tooth plate 10 and the gear 710.

[0043] After stamping is completed, the punch 3, driven upward by the electric telescopic rod 9, causes the aforementioned structure to reverse. At this time, the longitudinal rod 705 rotates clockwise in the direction of view of the device. This causes the rotating wheel 708 on the crank block 707 to press against the upper inner wall of the moving groove plate 701, which in turn causes the left and right moving groove plates 701 to move in opposite directions. This causes the half-body die 6 to move in opposite directions, allowing the stamped part to fall more easily. During the reverse movement of the half-body die 6, the storage cylinder 802 moves together with the half-body die 6. Thus, the L-shaped push rod 801 remains stationary, and the storage cylinder 802 moves closer to the L-shaped push rod 801. Under the thrust of the piston block 803, the gas in the storage cylinder 802 is pushed into the L-shaped cavity 804 and discharged through the air outlet 805. This ensures better separation of the stamped parts and cleans dust and impurities inside the half-body die 6 during the air blowing process. When the punch 3 rises to a certain height, the vertical tooth plate 10 disengages from the gear 710. At this time, the half-body die 6 moves relative to the piston block 803 under the push of the push spring 12. At this time, the storage cylinder 802 starts to suck in air under the movement of the piston block 803, ensuring the air blowing cleaning effect on the lower side. The second check valve 808 on the storage cylinder 802 can only suck in air and not expel air, while the first check valve 807 in the connecting port 806 can only expel air and not suck in air, which can ensure the separation of air sucking and expelling in the storage cylinder 802. After the stamped parts are processed, the operator needs to take them out and then put them into the processing material to prepare for the next stamped part processing.

[0044] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
