Description

Technical Field

[0001] The invention relates to the field of material science and engineering technology, and in particular to a device for controlling the stamping deformation stress of an aluminum bronze stamping part. Background Art

[0002] Stamping is a common metal processing method. Pressure is applied to the sheet through the stamping die to cause it to undergo plastic deformation, thereby obtaining the desired shape and size. The control device for the stamping deformation stress of stamping parts usually adopts a closed-loop control system composed of pressure sensors, displacement sensors, controllers, etc. By real-time monitoring of the pressure and displacement changes during the stamping process, the stroke and pressure of the stamping machine are automatically adjusted to achieve the purpose of controlling the deformation stress of the stamping parts. Controlling the stamping deformation stress can make the internal structure of the stamping parts more uniform, reduce internal defects and residual stress, and thus enhance the reliability and service life of the product.

[0003] There are still many inconveniences in the use of current equipment;

[0004] The specific defects are as follows:

[0005] First, when the bronze raw material is stamped by the punch, the punch will hit the raw material at high speed, thereby generating a large impact force. Due to the friction between the mold and the raw material, when the friction on the mold surface is insufficient, the bronze raw material placed on the mold surface will move or deform in the mold under the push of the punch. In addition, during the stamping process, the aluminum bronze material will produce stress concentration due to the impact force of the punch. Through manual positioning, stress concentration will cause the strength and toughness of the final stamped parts to decrease.

[0006] Secondly, in the processing of aluminum bronze stamping parts, due to the performance characteristics of the material itself, stamping deformation is prone to occur during the stamping process. Due to the limited space inside the mold and the deformation of the stamping parts inside the mold, the stamping parts cannot be removed during the stamping process. These problems will cause the interruption of the production process, thereby affecting the quality and production efficiency of the product. In addition, stress concentration problems will occur during the stamping process, which will cause damage to the mold, resulting in the stamped parts being stuck inside the mold, thus affecting the stamping efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] refer to Figures 1 to 8 According to a preferred embodiment of the present invention, a device for controlling the stamping deformation stress of aluminum bronze stamping parts will be described in detail below. The device for controlling the stamping deformation stress of aluminum bronze stamping parts includes a support leg 1, a top fixing box 2 is fixedly connected to the top of the support leg 1, a positioning mechanism 3 for positioning and fixing the bronze raw material is arranged inside the top fixing box 2, and a pushing mechanism 4 for collecting bronze stamping parts is arranged inside the top fixing box 2;

[0040] The positioning mechanism 3 includes a power slider 312 for providing power to the positioning mechanism 3;

[0041] The pushing mechanism 4 includes a driving block 412 for the bronze stamping part to be ejected from the die.

[0042] The positioning mechanism 3 includes a mold block 311, which is fixedly connected to the inside of the top fixing box 2, a power slider 312 is slidably connected to the inside of the top fixing box 2, a fixed top block 313 is fixedly connected to the upper surface of the power slider 312, a pushing support rod 318 is rotatably connected to the inside of the top fixing box 2, the pushing support rod 318 is L-shaped, and the pushing support rod 318 is fixedly connected to the end away from the power slider 312 with a transverse solid block 3111, and the lower surface of the pushing support rod 318 is fixedly connected to a contact support rod 319, and a restoring spring 3110 is fixedly connected to the inside of the top fixing box 2, and the restoring spring 3110 is fixedly connected to the pushing support rod 318, and the inside of the top fixing box 2 is fixedly connected.

[0043] The effects achieved by this embodiment are as follows: when the bronze raw material is stamped by the punch, the punch will hit the raw material at high speed, thereby generating a large impact force. Due to the friction between the mold and the raw material, when the friction on the mold surface is insufficient, the bronze raw material placed on the mold surface will move or deform in the mold under the push of the punch. The bronze raw material on the surface of the mold block 311 is positioned and fixed by the transverse solid block 3111 and the downward pressure solid block 317, which solves the problem of the bronze raw material being offset during the stamping process.

The connecting support block 415 and the power round block 416 are fixedly connected. A downward pressing block 417 is fixedly connected to the surface of the power round block 416, and a movable push block 418 is slidably connected to the inside of the driving round block 412, and a movable spring 419 is fixedly connected to the inside of the driving round block 412. The movable spring 4 19 is fixedly connected with the movable push block 418, the top fixed box 2 is fixedly connected with a supporting spring 413 inside, the supporting spring 413 and the driving round block 412 are fixedly connected, the top fixed box 2 is fixedly connected with a fixed inclined block 414 inside, the end of the movable push block 418 away from the mold block 311 is set as an inclined surface, and the end of the fixed inclined block 414 close to the mold block 311 is set as an inclined surface, the inclined surface of the movable push block 418 is fitted with the inclined surface of the fixed inclined block 414, the downward pressing block 417 and the fixed inclined block 414 are both located inside the sliding path of the movable push block 418, the thickness of the downward pressing block 417 and the fixed inclined block 414 is half the thickness of the movable push block 418, and the downward pressing block 417 and the fixed inclined block 414 are not located in the same horizontal plane.

[0045] The effects achieved by this embodiment are as follows: During the processing of aluminum-bronze stamping parts, due to the performance characteristics of the material itself, stamping deformation is prone to occur during the stamping process. Due to the limited space inside the mold and the deformation of the stamping parts inside the mold, the stamping parts cannot be removed during the stamping process. These problems will cause the production process to be interrupted, thereby affecting the quality and production efficiency of the product. The movement state of the toggle support rod 411 is controlled, and the stamping parts inside the mold block 311 are ejected by toggle support rod 411, which solves the problem that the stamping parts are difficult to remove from the mold. The automatic ejection mechanism can quickly and efficiently eject the stamped stamping parts from the mold, reducing the waiting time in the production process and improving the overall production efficiency. Compared with manual operation, automatic ejection can achieve a continuous workflow, reduce manual intervention, and thus improve the speed and output of the production line.

[0046] The following is the entire working process and working principle of the above embodiment:

[0047] Initially: the restoring spring 3110 is in a compressed state, the adjusting fixed shaft 315 is located at the end of the adjusting slot 316 away from the downward pressing fixed block 317, the downward pressing support rod 314 and the pushing support rod 318 are located on both sides of the mold block 311, the surface of the contact support rod 319 is in contact with the surface of the power slider 312, the movable spring 419 and the supporting spring 413 are in an uncompressed state, and the downward pressing block 417 is located above the movable pushing block 418.

[0048] During operation: when the bronze raw material is placed on the upper surface of the mold block 311 and punched by the punch, the fixed top block 313 is fixedly connected to the electric telescopic rod. When the bronze raw material on the surface of the mold block 311 is positioned, the electric telescopic rod drives the power slider 312 to slide downward. The power slider 312 slides downward. Since the return spring 3110 is fixedly connected to the surface of the push support rod 318, the lower surface of the push support rod 318 is fixedly connected with the contact support rod 319, and the contact support rod 319 is in contact with the upper surface of the power slider 312, the contact support rod 319 on the surface of the push support rod 318 loses power. The slider 312 is limited, and the support rod 318 is pushed to rotate on the inner wall of the top fixing box 2 under the push of the return spring 3110, so that the bronze raw material on the surface of the mold block 311 is pushed to align with the mold block 311 by pushing the transverse solid block 3111 on the surface of the support rod 318. By accurately controlling the alignment of the aluminum bronze stamping part and the mold block 311, the deformation and deviation in the stamping process can be reduced, thereby improving the accuracy and consistency of the stamping part, and the precise centering can reduce the residual stress generated in the stamping process, which helps to reduce the risk of deformation and cracking of the stamping part in subsequent use and improve its durability;

[0049] At the same time, since the fixed top block 313 is fixedly connected to the upper surface of the power slider 312, the power slider 312 slides downward, thereby driving the downward pressing support rod 314 to slide downward through the fixed top block 313. Since the adjustment fixed shaft 315 is slidably connected to the adjustment groove 316 inside the downward pressing support rod 314, and the downward pulling force is given to the downward pressing support rod 314 by pulling the fixed top block 313, and the adjustment fixed shaft 315 will slide in the adjustment groove 316 inside the downward pressing support rod 314. The inner wall of the internal adjustment groove 316 restricts the pressing support rod 314, so that the pressing support rod 314 rotates toward the mold block 311 inside the top fixing box 2, so that the pressing block 317 fixedly connected to the surface of the pressing support rod 314 is parallel to the mold block 311, thereby driving the lower surface of the pressing block 317 to be parallel to the bronze raw material on the surface of the mold block 311. When the power slide block 312 continues to slide downward, the pressing support rod 314 is restricted by the adjusting fixed shaft 315. A vertical downward sliding is performed to make the downward pressing solid block 317 contact the bronze raw material on the surface of the mold block 311 from top to bottom, so that the downward pressing solid block 317 fixes the bronze raw material from top to bottom. The top-down fixing method can ensure that the pressure is evenly distributed on the surface of the bronze raw material, reduce local stress concentration, and thus reduce the possibility of deformation. By driving the power slider 312 to slide, the bronze raw material is pushed to align with the mold block 311 through the transverse solid block 3111, and the bronze raw material positioned on the surface of the mold block 311 is fixed by the downward pressing solid block 317, which solves the problem of displacement of the bronze raw material during the stamping process. The positioning mechanism 3 can quickly and accurately position and fix the raw material, reducing the time for manually adjusting the position of the bronze raw material during the stamping process, thereby improving the production efficiency of bronze stamping parts, and the positioning mechanism 3 fixes and limits the bronze raw material, which can effectively prevent the displacement and deformation of the raw material during the stamping process, thereby reducing the generation of waste and reducing production costs.

[0050] Furthermore, through the cooperation of the top fixing box 2 and the pushing mechanism 4, when the power slider 312 slides downward, since the power round block 416 is fixedly connected to the power slider 312 through the connecting support block 415, the power slider 312 slides downward, thereby driving the power round block 416 to slide downward through the connecting support block 415, and since the downward pressing block 417 is located above the movable pushing block 418, and the movable pushing block 418 is located inside the sliding path of the downward pressing block 417, the downward pressing block 417 slides downward, thereby driving the round block 412 to slide downward by pushing the movable pushing block 418, thereby driving the toggle support rod 411 to slide downward by driving the round block 412, and the movable pushing block 418 stops above the fixed inclined block 414. When the bronze original inside the mold block 311 is After the material stamping is completed, the electric telescopic rod drives the power slider 312 to continue to slide down. As the power slider 312 continues to slide down, since the side of the movable push block 418 close to the supporting spring 413 is set as an inclined surface, and the side of the fixed inclined block 414 close to the toggle support rod 411 is an inclined surface, the inclined surface of the movable push block 418 fits the inclined surface of the fixed inclined block 414. Under the push of the inclined surface of the fixed inclined block 414, the movable spring 419 is compressed, and the movable push block 418 extends to the inside of the power round block 416. The downward pressing block 417 does not contact the movable push block 418, driving the round block 412 to lose the thrust of the downward pressing block 417, and driving the round block 412 to slide up under the push of the supporting spring 413, so that the stamping part inside the mold block 311 is ejected through the toggle support rod 411.

[0051] By controlling the movement state of the toggle support rod 411 and ejecting the stamping parts inside the mold block 311 by toggle the support rod 411, the problem that the stamping parts are difficult to take out from the mold is solved. The automatic ejection mechanism can quickly and efficiently eject the stamped stamping parts from the mold, reducing the waiting time in the production process and improving the overall production efficiency. Compared with manual operation, automatic ejection can achieve a continuous workflow and reduce human intervention, thereby improving the speed and output of the production line. In addition, the stamping parts have complex shapes and structures, and manual ejection may encounter difficulties or cannot guarantee the ejection effect. By toggling the support rod 411 to eject the stamping parts inside the mold block 311, it can adapt to stamping parts of different shapes and sizes and ensure smooth removal.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
