Description

Technical Field

[0001] This utility model belongs to the field of metal product processing technology, and specifically relates to a stamping and forming device for metal product processing. Background Technology

[0002] A stamping forming apparatus for metal product processing is a device that uses stamping dies under the action of a press to plastically deform or separate metal sheets to obtain parts of specific shapes and sizes. This apparatus mainly consists of a press, stamping dies, and auxiliary systems. The press provides power for the stamping process; common types include mechanical presses and hydraulic presses, and the pressure and stamping speed can be adjusted according to processing requirements. The stamping die is the core of the apparatus, consisting of a punch and a die. Its design precision directly affects the quality of the parts. Different dies can achieve various processes such as blanking, bending, deep drawing, and forming. The auxiliary system includes a feeding mechanism and a unloading device, used to ensure accurate material feeding and smooth demolding of the finished product.

[0003] Announcement No. "CN220942748U" discloses a stamping device for metal product processing, including a worktable with a through area at the bottom. A feeding unit is added within the through area. A stamping groove is recessed into the upper surface of the worktable, and the output end of the feeding unit acts into the stamping groove. A guide stamping unit is added to the upper surface of the worktable, cooperating with the stamping groove. This stamping device for metal product processing, by adding a guide stamping unit to the worktable, can limit and guide the stamped parts during vertical sliding, preventing displacement. Furthermore, with the cooperation of the feeding unit, it can assist in unloading the stamped metal parts from the stamping groove. The feeding unit can be operated electrically or manually, allowing for flexible selection based on different operating environments, enriching its functionality, and enabling continued feeding even when the drive motor or other components are damaged.

[0004] While the aforementioned utility model allows for flexible selection to suit different usage environments, enriches functionality, and can continue material feeding even when the drive motor is damaged, the workpiece cannot automatically detach from the mold after the stamping process, requiring manual removal. This not only increases the labor intensity of workers but also significantly extends the processing cycle of individual products, reducing production efficiency. Especially in mass production, frequent manual intervention can severely slow down the overall production progress, affecting the company's production plans and order delivery. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a stamping forming device for metal product processing, so as to solve the problem that after the stamping forming process is completed, the workpiece cannot be automatically removed from the mold and can only be manually removed by hand. This not only increases the labor intensity of workers, but also greatly extends the processing cycle of a single product and reduces production efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A stamping forming apparatus for metal product processing includes a worktable, a base symmetrically fixedly connected to the bottom of the worktable, a top plate fixedly connected to the top of the worktable via a support column, a cylinder mounted on the top of the top plate, a lifting seat fixedly connected to the telescopic end of the cylinder, a stamping head fixedly connected to the bottom of the lifting seat via an mounting plate, a mold fixedly connected to the top of the worktable via a fixed seat, a mold groove opened on the top of the mold, a receiving groove opened at the bottom of the mold groove, an ejector plate slidably connected inside the receiving groove, an ejector assembly installed at the bottom of the worktable, and a buffer assembly sleeved on the outside of the support column. The ejection assembly includes a rotating column, a threaded hole, a threaded rod, a limit block, a drive gear, a driven gear, and a drive motor. The rotating column is symmetrically rotatably connected to the bottom of the worktable. A threaded hole is opened at the bottom of the rotating column, communicating with the interior of the receiving groove. A threaded rod is threadedly connected inside the threaded hole, with its top end rotatably connected to the bottom of the ejection plate. A limit block is fixedly connected to the bottom end of the threaded rod. A driven gear is fixedly sleeved on the outside of the rotating column. A drive gear is rotatably connected to the bottom of the worktable, and a drive motor is installed at the bottom of the worktable. The output end of the drive motor is fixedly connected to the drive gear. The diameter of the drive gear is larger than that of the driven gear, and the drive gear and driven gear mesh with each other. This avoids problems such as scratches and deformation of the workpiece surface caused by improper operation during manual removal. It also allows the workpiece to be promptly removed from the mold, reducing quality risks such as uneven internal stress and cracking caused by prolonged exposure to temperature and pressure changes within the mold. This ensures the dimensional accuracy and appearance quality of the product and reduces the defect rate.

[0007] As a preferred technical solution, guide grooves are symmetrically opened on both sides of the receiving groove, and guide blocks are symmetrically fixedly connected to both sides of the ejector plate. The guide blocks and guide grooves are slidably connected. The guide grooves of the receiving groove and the guide blocks of the ejector plate slide together, which can accurately limit the displacement of the ejector plate, avoid deviation and jamming, ensure smooth ejection, and improve the reliability of demolding and the smooth operation of the equipment.

[0008] As a preferred technical solution, the buffer assembly includes a buffer spring, a buffer plate, and a pressure block. The buffer plate is slidably connected to the support column, and the buffer spring is fixedly connected at both ends to the bottom of the buffer plate and the top of the worktable, respectively. The pressure block is slidably connected to the support column, and its top is fixedly connected to the bottom of the lifting seat. This effectively absorbs and mitigates the impact force generated during the stamping process when the die contacts the workpiece. When the press drives the die downwards, traditional devices may experience severe vibrations due to rigid collisions. However, the buffer assembly transforms the instantaneous impact force into a gradual force transmission through elastic deformation or hydraulic damping, reducing the overall vibration amplitude of the equipment.

[0009] As a preferred technical solution, a buffer pad is glued to the top of the buffer plate. The buffer pad is made of soft rubber. Through its own elastic deformation, the buffer pad can further absorb the stamping impact, reduce the rigid contact between the mold and the workpiece, protect the surface finish of the workpiece, reduce equipment vibration, and improve stamping stability and component life.

[0010] As a preferred technical solution, the bottom of the mounting plate is symmetrically fixed with limit posts, and the top of the mold is symmetrically opened with limit holes. The limit posts and limit holes are plugged in. The bottom limit posts of the mounting plate are plugged in with the top limit holes of the mold, which can accurately align the mold and the mounting plate, avoid misalignment during stamping, ensure processing accuracy, and improve the stability of equipment operation and product qualification rate.

[0011] As a preferred technical solution, the top of the lifting seat is symmetrically provided with guide holes, and the support column and the guide holes are slidably connected. The guide holes of the lifting seat and the support column are slidably connected, which can accurately guide the vertical movement of the lifting seat, avoid deviation and tilting, ensure accurate stamping alignment, and improve the stability of equipment operation and processing reliability.

[0012] In summary, the present invention has the following main advantages: First, in this utility model, after stamping is completed, the drive motor is started to control the drive gear to rotate. The drive gear drives the driven gear to rotate, and the driven gear drives the rotating column to rotate, thereby enabling the threaded hole and the threaded rod to perform threaded transmission, thereby controlling the threaded rod to move forward. The threaded rod drives the ejector plate to rise, ejecting the metal part inside the mold groove and completing the demolding. This avoids problems such as scratches and deformation of the workpiece surface caused by improper operation when manually removing parts. At the same time, it allows the workpiece to be removed from the mold in a timely manner, reducing the quality risks such as uneven internal stress and cracking caused by temperature and pressure changes due to prolonged stay in the mold. This ensures the dimensional accuracy and appearance quality of the product and reduces the defect rate. Secondly, in this invention, the starting cylinder controls the lowering of the lifting seat. The lifting seat, through the mounting plate, drives the stamping head to descend, and simultaneously, the lifting seat drives the pressure block to descend. The pressure block slides outside the support column, pressing against the buffer plate. The buffer plate slides outside the support column, pressing against the buffer spring, which is then compressed. This absorbs and disperses the impact force during stamping, effectively absorbing and mitigating the impact force generated at the moment of contact between the mold and the workpiece during the stamping process. When the press drives the mold downward, traditional devices may experience severe vibration due to rigid collisions. However, the buffer assembly, through elastic deformation or hydraulic damping, transforms the instantaneous impact force into a gradual force transmission, reducing the overall vibration amplitude of the equipment.

The drive gear 145 drives the driven gear 146 to rotate. The driven gear 146 drives the rotating column 141 to rotate, thereby enabling the threaded hole 142 and the threaded rod 143 to perform threaded transmission, thereby controlling the threaded rod 143 to move forward. The threaded rod 143 drives the ejector plate 13 to rise, ejecting the metal parts inside the mold groove 11 and completing the demolding.

The guide blocks 16 and the guide grooves 15 are slidably connected. When the ejector plate 13 is raised or lowered, the raising plate drives the guide blocks 16 to slide inside the guide grooves 15.

[0017] refer to Figure 1 The buffer assembly 17 includes a buffer spring 171, a buffer plate 172, and a pressure block 173. The buffer plate 172 is sleeved on the outside of the support column 3 and is slidably connected to the support column 3. The buffer spring 171 is sleeved on the outside of the support column 3 and its two ends are fixedly connected to the bottom of the buffer plate 172 and the top of the worktable 2, respectively. The pressure block 173 is sleeved on the outside of the support column 3 and is slidably connected to the support column 3. The top of the pressure block 173 is fixedly connected to the bottom of the lifting seat 6. When the cylinder 5 is activated, the lifting seat 6 is lowered. The lifting seat 6 drives the punch head 8 to lower through the mounting plate 7. At the same time, the lifting seat 6 drives the pressure block 173 to lower. The pressure block 173 slides on the outside of the support column 3 and presses against the buffer plate 172. The buffer plate 172 slides on the outside of the support column 3 and presses against the buffer spring 171, which is compressed to absorb and disperse the impact force during punching.

[0018] refer to Figure 3The buffer plate 172 has a buffer pad 18 glued to its top. The buffer pad 18 is made of soft rubber. The buffer pad 18 can further absorb the stamping impact through its own elastic deformation, reduce the rigid contact between the mold 10 and the workpiece, protect the surface finish of the workpiece, reduce equipment vibration, and improve stamping stability and component life.

When the cylinder 5 is started to control the lifting seat 6 to rise and fall, the lifting seat 6 drives the guide holes 19 to slide on the outside of the support column 3.

[0021] Operating principle and advantages: First, the metal part is placed inside the mold groove 11 of the mold 10. The cylinder 5 is activated, controlling the lifting seat 6 to descend. The lifting seat 6, through the mounting plate 7, drives the stamping head 8 to descend. The stamping head 8 stamps the metal part inside the mold groove 11. Simultaneously, the lifting seat 6 drives the pressure block 173 to descend. The pressure block 173 slides outside the support column 3, pressing against the buffer plate 172. The buffer plate 172 slides outside the support column 3, pressing against the buffer spring 171, thus buffering the metal part. The spring 171 is compressed to absorb and disperse the impact force during stamping. After stamping is completed, the drive motor 147 is started to control the drive gear 145 to rotate. The drive gear 145 drives the driven gear 146 to rotate, and the driven gear 146 drives the rotating column 141 to rotate, so that the threaded hole 142 and the threaded rod 143 perform threaded transmission, thereby controlling the threaded rod 143 to move forward. The threaded rod 143 drives the ejector plate 13 to rise, ejecting the metal parts inside the mold groove 11 and completing the demolding. This invention avoids problems such as scratches and deformation on the workpiece surface caused by improper operation during manual removal. At the same time, it allows the workpiece to be removed from the mold 10 in a timely manner, reducing the quality risks such as uneven internal stress and cracking caused by prolonged stay in the mold 10 and temperature and pressure changes. This ensures the dimensional accuracy and appearance quality of the product and reduces the defect rate.
