Description

Technical Field

[0001] This utility model relates to the field of metal stamping technology, specifically to a metal stamping forming equipment. Background Technology

[0002] Metal stamping equipment is the core equipment for mass production of metal components. It is widely used in the processing of various metal parts with bending structures in industries such as home appliances, automobiles, and electronics. In particular, for the stamping process of inward bending of metal parts, there is a high-intensity contact and extrusion between the stamping die and the metal material during the forming process. The friction between the two will generate a large friction force. This friction will not only increase the energy consumption in the stamping process, but also easily lead to quality defects such as scratches and abrasions on the surface of the metal parts. This will directly affect the appearance accuracy and performance of the product. In severe cases, it may even cause the metal parts to be scrapped and reduce the production qualification rate. To solve this problem, the industry generally adopts the method of applying lubricant to the surface of the hardware parts to be processed before stamping. The lubricant forms a protective film between the hardware parts and the upper die, reducing direct friction between the contact surfaces and thus reducing the risk of scratches. However, due to the structural design characteristics of metal stamping equipment, the internal working space used to accommodate the positioning of metal parts and the movement of the upper mold is usually quite compact. This limited space not only imposes strict restrictions on the installation position and size of the lubricant spraying device, but also hinders the spray nozzle from forming a reasonable spray angle and distance with the surface of the metal parts. As a result, the lubricant is difficult to evenly and comprehensively cover the bending area and surrounding key contact parts of the metal parts, making these areas still face a high risk of scratching during subsequent stamping processes. Therefore, a hardware stamping and forming equipment is proposed to address the above problems. Utility Model Content

[0016] Please see Figures 1-6 This utility model provides a technical solution: A metal stamping forming equipment includes a support platform 1, a lower die base 2 fixed at the center of the top of the support platform 1, a support mechanism 3 slidably connected to the inner side of the lower die base 2, and a self-lubricating upper die mechanism 5 mounted above the support mechanism 3; the self-lubricating upper die mechanism 5 includes two pressure seats 51, wedge-shaped seats 52 slidably connected to the inner side of the two pressure seats 51, an installation cavity 53 opened on the inner side of the wedge-shaped seats 52, a pressure lubrication mechanism 54 fixed inside the installation cavity 53, and a positioning plate 55 slidably connected to the bottom of the inner side of the two pressure seats 51; the pressure lubrication mechanism 54 includes a storage box 541 for storing... The bottom end of the box 541 is fixed with an upper conveying pipe 542. The bottom of the upper conveying pipe 542 is slidably connected with a lower conveying pipe 543. The bottom end of the lower conveying pipe 543 is fixed with a pressure head 544. A nozzle 545 is fixed on one side of the pressure head 544. An adjustment groove 546 is opened on the outer wall of the lower conveying pipe 543. A lower connecting sleeve 547 is slidably connected to the outer side of the lower conveying pipe 543. A positioning protrusion 5471 is fixed on the inner side of the lower connecting sleeve 547. A support spring 548 is fixed on the upper surface of the lower connecting sleeve 547. An upper connecting sleeve 549 is fixed on the top of the support spring 548.

[0017] As a further implementation of this solution, a filling tube 56 is fixedly fixed through one side of the storage box 541. The filling tube 56 extends to the outside of the wedge-shaped seat 52. A storage cavity 57 is opened in the middle of the bottom end of the wedge-shaped seat 52. The storage cavity 57 is used to store the positioning plate 55 to avoid motion interference. As a further implementation of this solution, the axis of the lower conveying pipe 543 and the axis of the upper conveying pipe 542 are located on the same central axis. A return spring 5421 is fixed at the top of the lower conveying pipe 543. The return spring 5421 is sleeved on the middle of the outer side of the upper conveying pipe 542. The lower surface of the pressure head 544 has a hemispherical structure. The top and bottom of the inner side of the adjusting groove 546 are both vertical structures. The middle of the inner side of the adjusting groove 546 has an inclined structure. The adjusting groove 546 and the positioning protrusion 5471 are in sliding fit. Specifically, the coaxial design of the lower conveying pipe 543 and the upper conveying pipe 542 ensures smooth lubricant transmission. The hemispherical lower surface of the pressure head 544 facilitates contact with the hardware. The adjusting groove 546 (vertical at the top and bottom, and inclined in the middle) works with the positioning protrusion 5471 to allow the lower conveying pipe 543 to rotate when moving, allowing the nozzle 545 to switch the spraying direction. This not only lubricates the bending parts of the hardware during processing, but also pre-sprays the hardware to be processed on the placement rack 7, expanding the lubrication coverage and further reducing friction damage. As a further implementation of this solution, the lower sleeve 547 is fixedly installed on the top of the positioning plate 55. The axis of the lower sleeve 547 and the axis of the lower conveying pipe 543 are located on the same central axis. The support spring 548 is sleeved on the outside of the lower conveying pipe 543. The support spring 548 is located between the upper sleeve 549 and the lower sleeve 547 to provide elastic buffer and avoid rigid contact damage to the parts during stamping. As a further implementation of this solution, the upper sleeve 549 is located above the lower sleeve 547. The axis of the upper sleeve 549 and the axis of the lower sleeve 547 are located on the same central axis. The upper sleeve 549 is rotatably engaged with the lower conveying pipe 543. The upper sleeve 549 is located inside the receiving cavity 57. The upper sleeve 549 is fixedly connected to the top of the inner side of the receiving cavity 57. The coaxial design of the upper sleeve 549 and the lower sleeve 547 ensures the coaxiality of the movement of each component of the pressure lubrication mechanism 54. As a further implementation of this solution, an elastic frame 6 is fixed on one side of the support mechanism 3. The elastic frame 6 includes two spring telescopic rods 61. The spring telescopic rods 61 are fixedly installed on the upper surface of the support platform 1. The telescopic ends of the two spring telescopic rods 61 are fixed with the same connecting rod 62. The connecting rod 62 is fixedly connected to the connecting frame 63. The elastic force of the spring telescopic rods 61 is transmitted to the support mechanism 3 through the connecting rod 62 and the connecting frame 63, which drives the stamped hardware parts to move upward, making it convenient to pick up the material. As a further implementation of this scheme, an electric cylinder 4 is fixed on one side of the top of the support platform 1. The telescopic end of the electric cylinder 4 is fixedly connected to the wedge seat 52 through a connecting plate. A placement rack 7 is fixed on the other side of the top of the support platform 1. The placement rack 7 is used to place the hardware parts to be processed, which facilitates the pre-spraying of the pressure lubrication mechanism 54 and enables the various parts of the equipment to work together.

[0018] Work process: The electric cylinder 4 is in the extended state, which drives the self-lubricating upper mold mechanism 5 to a high position; the spring extension rod 61 of the elastic frame 6 extends naturally, and the support mechanism 3 remains horizontal inside the lower mold base 2; the storage box 541 of the pressure lubrication mechanism 54 has been filled with sufficient lubricant through the filling pipe 56, the reset spring 5421 pushes the lower conveying pipe 543 to protrude downward, the nozzle 545 is aligned with the area to be processed above the lower mold base 2 and the support mechanism 3, and the metal parts to be stamped are placed on the upper surface of the lower mold base 2 and the support mechanism 3, and the unprocessed metal parts are placed on the placement rack 7; Next, the electric cylinder 4 is activated. Its telescopic end drives the wedge seat 52 and the entire self-lubricating upper mold mechanism 5 downward through the connecting plate, gradually approaching the hardware to be processed. The pressure head 544 first contacts the hardware and, under the downward pressure, the lower conveying pipe 543 moves towards the upper conveying pipe 542, compressing the return spring 5421. During this process, the positioning protrusion 5471 on the inner side of the lower sleeve 547 slides along the vertical section at the top of the adjusting groove 546, and the nozzle 545 remains aligned with the bends on both sides of the hardware. The storage box 541... The lubricating fluid is sprayed from the nozzle 545 through the upper conveying pipe 542 and the lower conveying pipe 543, evenly covering the bending area to form a lubricating film. As the self-lubricating upper mold mechanism 5 continues to move downward, the positioning protrusion 5471 slides into the inclined section in the middle of the adjusting groove 546, pushing the lower conveying pipe 543 to rotate 90° around the axis. The nozzle 545 turns towards the placement frame 7 to pre-spray the lubricating fluid onto the unprocessed hardware parts on the frame. At the same time, the support spring 548 is squeezed and contracted by the upper sleeve 549 and the lower sleeve 547 to buffer the downward impact force. When the lower surface of the conveying pipe 543 is flush with the lower surface of the pressure seat 51, the positioning protrusion 5471 slides into the bottom vertical section of the adjusting groove 546, the nozzle 545 stops rotating, the pressure seats 51 on both sides slide along the inner side of the wedge seat 52, apply pressure to the middle of the hardware, push the support mechanism 3 to move down along the inner side of the lower die seat 2, the spring telescopic rod 61 retracts, during the stamping process, the positioning plate 55 moves up with the pressure seat 51 and gradually hides in the receiving cavity 57 of the wedge seat 52 to avoid interfering with the stamping action, and finally bends the hardware into the predetermined shape; After stamping is completed, the telescopic end of the control electric cylinder 4 extends, driving the self-lubricating upper die mechanism 5 to reset upward. The pressure of the pressure seat 51 on the support mechanism 3 disappears, and the spring telescopic rod 61 of the elastic frame 6 releases its elastic force. Through the connecting rod 62 and the connecting frame 63, the support mechanism 3 moves upward, lifting the stamped hardware. The operator can easily take away the finished product. The self-lubricating upper die mechanism 5 resets to the initial high position. The lower conveying pipe 543 returns to the downward protruding state under the action of the reset spring 5421. The positioning plate 55 is removed from the receiving cavity 57 and reset. The nozzle 545 rotates back to the initial position, and the equipment waits for the next stamping operation.
