Description

Technical Field

[0001] The present invention relates to the technical field of metal product processing, and in particular to a punching device for metal product processing. Background Art

[0002] There are many manufacturing processes for metal products, mainly including casting, plastic forming, machining, welding, etc. These processes have their own characteristics and are suitable for the production of metal products of different shapes, sizes and performances. For example, the casting process can produce parts with complex shapes and complex inner cavities; the plastic forming process is suitable for the production of forgings with certain mechanical properties and dimensional accuracy; the machining process can accurately process and trim metal products; the welding process can connect multiple metal products into a whole;

[0003] Metal stamping is widely used in many fields such as automobiles, home appliances, electronics, aerospace, and military industry. For example, a large number of stamping parts are used in the car body, chassis, fuel tank, radiator, etc.; the shell and internal structural parts of household appliances are also often processed by stamping; in the aerospace field, stamping parts are used to manufacture key components such as aircraft skins and wing beams;

[0004] In the stamping production process of metal products, after the stamping operation is completed, a large amount of heat accumulates due to the conversion of mechanical energy and internal energy in the stamping process, which significantly increases the surface temperature of the metal products. This temperature increase phenomenon becomes a challenge in the subsequent retrieval operation. When manually extracting these newly stamped metal products, it is necessary to wait for them to cool naturally to a temperature that is safe to touch. This process is not only time-consuming and inefficient, but also greatly increases the physical burden and work intensity of the operators. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

This design helps the ejector rod to accurately eject the metal product after the stamping is completed.

[0013] Preferably, a connecting frame is fixedly provided on the bottom surface of the fixed plate, and moving rods are fixedly provided on the left and right sides of the connecting frame. A moving groove is opened on the side of the fixed frame, and the other end of the moving rod passes through the moving groove and is slidably connected to the inner wall of the moving groove. The design of the connecting frame and the moving rod enables the fixed plate to move more stably during the stamping process, which can reduce errors caused by vibration or offset, thereby improving the accuracy of the stamped product and ensuring that the path of the fixed plate during the movement is accurately controllable, which is conducive to achieving high-precision stamping operations.

[0014] Preferably, a telescopic rod is hingedly provided on the bottom surface of the connecting frame, and the other end of the telescopic rod is hingedly connected to the inner wall of the placement seat. The telescopic end of the telescopic rod is sleeved with a first spring, and the two ends of the first spring are respectively fixedly connected to the telescopic rod and the telescopic end of the telescopic rod. The first spring is sleeved on the telescopic rod, which plays a good buffering role. During the stamping process, when the fixed plate is subjected to impact or vibration, part of the energy can be absorbed by the spring, reducing the damage to the fixed plate and connecting parts caused by these impacts, thereby extending the service life of the equipment. At the same time, the buffering effect also helps to reduce the impact of noise and vibration on the working environment.

This design enables the adjusting block to automatically adjust its position as needed, thereby driving the driving rod and positioning plate hinged thereto to move.

[0017] Preferably, the lower end of the second cylinder output shaft passes through the fixed frame and extends to the bottom of the fixed frame, the bottom surface of the second cylinder output shaft is fixedly connected to the moving frame, the bottom surface of the moving plate is fixedly provided with a stamping plate, the top surface of the moving plate is fixedly provided with a connecting rod, the upper end of the connecting rod passes through the moving frame and is slidably connected to the moving frame, and a second spring is sleeved on the outer side of the connecting rod, and the upper and lower ends of the second spring are respectively fixedly connected to the moving frame and the moving plate.

The second spring sleeved on the outer side of the connecting rod plays a role of buffering and shock absorption during the stamping process. When the stamping plate contacts and stamps the metal sheet, the spring can absorb part of the impact energy, reduce vibration and noise during the stamping process, and protect the stamping equipment and mold from damage.

[0019] The present invention provides a punching device for metal product processing, which has the following beneficial effects:

[0020] (1) The present invention drives the sliding rod and the sliding plate to move synchronously when the moving plate moves, the sliding plate drives the moving rod to move, and the moving rod drives the fixed plate and the push rod to move, so that the top surface of the push rod and the top surface of the receiving plate are on the same horizontal line. After the stamping is completed, the second cylinder drives the moving plate back to its original position, so that the sliding rod, the sliding plate, the fixed plate and the push rod also return to their original positions, and the metal product on the receiving plate is ejected. Through the reset action of the second cylinder, the push rod is automatically driven to rise, and the metal product on the receiving plate is ejected without manual intervention, which greatly improves the production efficiency and the degree of automation, reduces the need for manual handling of metal products, and achieves the effect of reducing labor intensity.

[0021] (2) The present invention drives the adjustment block to move in the vertical direction through the first cylinder. When the adjustment block moves, it drives the left and right driving rods to deflect. During the deflection of the left and right driving rods, the left and right positioning plates are driven to move closer to or away from each other. By accurately controlling the stroke of the first cylinder and the moving distance of the positioning plate, accurate clamping and positioning of the metal product can be achieved, thereby achieving the effect of improving processing accuracy and product quality.

[0022] (3) The present invention drives the movable frame and the movable plate to move by the second cylinder, and the movable plate drives the stamping plate to move toward the metal product, and the stamping plate stamps the metal product. During the stamping process, the second spring expands and contracts to reduce the impact force between the movable plate and the stamping plate, reducing the vibration and noise generated during the stamping process, which helps to extend the service life of the equipment and achieves the effect of improving production safety.
