Description

Technical Field

[0001] The invention relates to the technical field of aluminum material processing and stamping, and in particular to a floating stamping die for aluminum material processing. Background Art

[0002] Aluminum products are made of aluminum and other alloy elements. They are usually first processed into castings, forgings, foils, plates, strips, tubes, bars, profiles, etc., and then made through processes such as cold bending, sawing, drilling, assembly, and coloring. Stamping dies are required for aluminum processing.

[0003] In modern manufacturing, floating stamping dies are used as efficient and precise processing tools for processing lightweight metals such as aluminum. Their background technology integrates professional knowledge in multiple fields such as material science, mechanical design, precision manufacturing, automatic control, and mechanical analysis. Aluminum is widely used in aviation, automobile, electronics, and construction industries due to its light weight, high strength, good formability, and thermal conductivity. However, its processing process places extremely high demands on the adaptability, precision, and durability of the mold.

[0004] The core technology of floating stamping dies lies in their unique floating design. By integrating precise springs or air pressure systems, the dies can be adaptively adjusted during the stamping process, effectively compensating for slight changes in material thickness, and ensuring the dimensional accuracy and surface quality of stamped parts. In addition, the selection of die materials and heat treatment processes, such as the use of high-hardness, high-wear-resistant alloy steel and precise heat treatment, ensure the stable performance and long life of the die under high-intensity, high-frequency stamping operations. The application of automated control technology, such as the integration of servo motor drives and precision sensors, achieves precise control and real-time monitoring of the stamping process, improving processing efficiency and safety. At the same time, mechanical analysis and simulation technologies, such as finite element analysis (FEA), simulate and calculate stress, strain, and deformation during the die design stage to ensure the rationality of the die structure and the stability of the processing process.

[0005] A stamping die for aluminum processing disclosed in the announcement number CN212370985U includes a bottom plate and a movable plate, the bottom of the bottom plate is bonded with a shock-absorbing pad by polyurethane glue, the middle end of the top of the bottom plate is fixedly connected with a shock-absorbing seat, the top of the movable plate is fixedly connected with a lower mold, the middle end of the outer surface of the lower mold is fixedly connected with an annular stopper, the inner surface of the annular stopper is provided with a slot, the inner side of the slot is bonded with a protective rubber pad by polyurethane glue, and the left and right ends of the top of the bottom plate are fixedly connected with support guide columns. The present invention solves the problem that the existing stamping die is prone to fragment splashing when stamping aluminum, causing harm to the staff, and a large impact will cause vibration, causing damage to the die, and reducing the service life of the die through the functions of a transparent protective cover, a support guide column, a sliding rod, an annular stopper, a protective rubber pad, a first spring, a shock-absorbing seat and a shock-absorbing pad.

[0006] Although the above patent solves the problem that the existing stamping dies are prone to splashing fragments when stamping aluminum, causing harm to the workers, and the large impact will cause vibration, causing damage to the mold and reducing the service life of the mold; however, the device lacks certain positioning components, and the device may be offset when in use, resulting in the processed aluminum plates being of different sizes.

[0007] Therefore, it is necessary to invent a floating stamping die for aluminum processing to solve the above problems. Summary of the invention

[0021] (III) Beneficial effects

[0022] The present invention provides a floating stamping die for aluminum processing, which has the following beneficial effects:

[0023] 1. The floating stamping die for aluminum processing, through the setting of the positioning component, when the workpiece is processed, the workpiece is placed on the placement block, and the floating positioning block limits the workpiece. The floating positioning block can accurately install the die on the device to ensure that the position of the workpiece does not shift during the stamping process.

At the same time, the floating positioning block reduces the time required for die adjustment and calibration, thereby improving the overall efficiency of the production line.

[0024] 2. The floating stamping die for aluminum processing, through the setting of auxiliary components, when the device is stamping, the extrusion plate stamps the workpiece, and the floating die core moves with the extrusion of the workpiece. The movement of the floating die core drives the telescopic rod to move. At this time, the reset spring is in a compressed state. After the stamping is completed, the reset spring drives the floating die core and the telescopic rod to reset. The floating die core resets to squeeze the workpiece, so that the workpiece is stripped, which can effectively reduce the friction and collision between the device and the workpiece, and avoid workpiece wear or finished product damage due to improper operation. At the same time, it can also enable the mold to quickly and accurately complete the stripping process after each stamping, which can speed up the production speed and reduce production delays caused by poor stripping.

[0025] 3. The floating stamping die for aluminum processing has a buffer component set up. When the device is stamping, the floating positioning block moves to drive the buffer hydraulic rod and the buffer spring to move. The buffer spring and the buffer hydraulic rod reduce the impact force generated when the device is in use, thereby reducing the vibration and deviation of the workpiece during stamping, maintaining the stable operation of the device, and improving the stability during pressing. Secondly, the buffer component can also reduce the impact of the impact on the device, thereby extending the service life of the device, thereby reducing maintenance and replacement costs.

[0044] In the present invention, the working steps of the device are as follows:

[0045] Step 1: When the workpiece is being processed, the workpiece is placed on the placement block 4, and the floating positioning block 802 limits the position of the workpiece. The floating positioning block 802 can accurately install the mold on the device to ensure that the position of the workpiece does not shift during the stamping process. It can ensure that the size of the aluminum parts stamped out each time is consistent and meets the design requirements. At the same time, the floating positioning block 802 reduces the time required for mold adjustment and calibration, thereby improving the overall efficiency of the production line;

[0046] The second step: when the device is stamping, the extrusion plate 6 stamps the workpiece, and the floating mold core 303 moves with the extrusion of the workpiece. The movement of the floating mold core 303 drives the telescopic rod 301 to move. At this time, the reset spring 302 is in a compressed state. After the stamping is completed, the reset spring 302 drives the floating mold core 303 and the telescopic rod 301 to reset. The floating mold core 303 resets to squeeze the workpiece, so that the workpiece is stripped, which can effectively reduce the friction and collision between the device and the workpiece, and avoid workpiece wear or finished product damage due to improper operation. At the same time, it can also enable the mold to quickly and accurately complete the stripping process after each stamping, which can speed up the production speed and reduce production delays caused by poor stripping.

[0047] The third step: when the device is punching, the floating positioning block 802 moves to drive the buffer hydraulic rod 901 and the buffer spring 902 to move. The buffer spring 902 and the buffer hydraulic rod 901 reduce the impact force generated when the device is in use, thereby reducing the vibration and displacement of the workpiece during punching, maintaining the stable operation of the device, and improving the stability during pressing. Secondly, the buffer assembly 9 can also reduce the impact of the impact on the device, thereby extending the service life of the device, thereby reducing maintenance and replacement costs.
