[0002] The existing marking technology has been widely used in many industrial productions, especially in the process of part processing, the marking not only identifies the product, but also plays a role in tracing and identification. Usually, the marking process is carried out in the next process after the part is processed. The marking position of these workpieces often needs to be on the processing surface, however, the traditional marking method usually requires that the parts are taken out after the stamping die completes stamping, and then sent to the next station for marking after being turned over. This process not only increases the operation of workpiece handling, turning over and other operations, but also needs additional process time, thereby leading to the decline of production efficiency, especially for large parts, this method undoubtedly significantly increases the production cost.

[0003] The main shortcomings of the current traditional process are the complexity of operation and the redundancy of process, especially when processing large parts, frequent manual intervention and additional equipment support are required. These shortcomings mainly come from the design limitations of the existing die, the parts need to be turned over manually or by mechanical equipment after stamping, and then sent to the next station for marking.

[0023] Referring to the accompanying drawings, Figure 1 and 2 , the present embodiment provides an exemplary structure of a bottom marking stamping die, aiming to solve the problems of process redundancy, low production efficiency and high cost existing in the existing marking technology. The die can complete stamping and marking operations in the same process, avoiding additional processes and complex operations in the traditional process, thereby effectively improving production efficiency and reducing production cost.

[0024] The overall structure of the bottom marking stamping die of the present embodiment includes an upper die assembly 1, a lower die assembly 2, a laser marking assembly 3, a smoke suction port 4 and several additional components. The upper die assembly 1 and the lower die assembly 2 are connected and matched by reset springs and guide mechanisms to ensure accurate closing and positioning of the die. The laser marking assembly 3 is installed in the lower die assembly 2, and the main function of this assembly is to accurately mark the parts.

[0025] Specifically, the lower die assembly 2 includes a lower die seat 2a, a forming jig 2b mounted on the lower die seat, and a beveled straight channel 2c provided on the lower die seat. The bottom of the straight channel 2c is provided with a laser marking assembly 3, and the marking head 3a faces the opening of the straight channel 2c. A rotating opening and closing mechanism 5 is mounted at the opening of the straight channel 2c, which includes a fan-shaped section rotating column and a driving unit connected to the rotating column, and the driving unit is composed of a motor and a speed reducer. The function of the driving unit is to control the opening and closing of the straight channel 2c by rotating the rotating column, to ensure that the marking operation is performed at the right time.

[0026] In addition, an air nozzle 6 is also provided in the straight channel 2c, which faces the marking head 3a and is used for cleaning the marking head 3a. The air nozzle 6 is connected to an external positive pressure device, which can remove smoke, oil stains and impurities that may be generated during the marking process by positive pressure blowing, and keep the marking head clean and in good working condition.

[0027] The smoke suction port 4 is located in the straight channel 2c of the lower die assembly 2, and has a plurality of counties at least one near the opening of the straight channel 2c. The smoke suction port 4 is connected to an external negative pressure device through a pipeline, and the negative pressure device can suck and discharge the smoke and gas generated during the marking process. In order to ensure that the inhaled smoke and harmful gas will not pollute the environment, the smoke suction port 4 is processed by a filtering assembly (not shown in the figure), which filters out smoke dust and other harmful substances. The filtering assembly uses high-efficiency filter material, which can effectively remove fine particulate matter and harmful gases in the smoke, and protect the health of the operators.

[0028] During the entire operation process, when the mold is working, the reset spring and the guide mechanism ensure the accurate cooperation and stable closure between the upper die assembly 1 and the lower die assembly 2. The laser marking assembly 3 in the lower die assembly 2 can accurately mark according to the position of the processing surface. Through the control of the rotating opening and closing mechanism 5, the opening of the straight channel 2c can be opened at the right time to allow the laser marking head to mark, and after the marking is completed, the rotating column is rotated again by the driving of the motor and the speed reducer to seal the opening of the straight channel. At the same time, the air nozzle 6 continuously cleans the marking head 3a by the action of the positive pressure device, to avoid the influence of pollutants on the surface of the marking head on the marking precision.

[0029] The smoke suction port 4 will work continuously during the entire marking process, sucking away the smoke generated during the marking, and filtering out harmful substances through the filtering assembly, to ensure the cleanliness and safety of the working environment.

[0030] In traditional stamping die design, marking is usually performed in the next process after part processing, and the marking position is usually required to be on the processed surface. At this time, in order to ensure the correct marking position, the workpiece often needs to be taken out of the stamping die, turned over and then sent to the next station for marking. This process increases the additional operations such as workpiece handling, turning over and adjusting position, resulting in reduced production efficiency. Especially for large parts, these additional operations not only waste time, but also significantly increase production costs. Especially when stamping and marking large parts, front marking not only increases the complexity of the process, but also requires special equipment support, such as turning over machinery, manual operation, etc., which undoubtedly further increases production costs.

[0031] Compared with the traditional marking method, the bottom marking stamping die of the embodiment directly completes the marking operation in the stamping process, avoiding additional operation steps such as part turning, handling and position adjustment, and significantly improving production efficiency. When processing large parts, the bottom marking function of the die is particularly significant, which can greatly reduce manual operation and reduce the need for turning equipment and personnel intervention, thereby reducing production costs. In addition, the high-precision marking effect provided by the laser marking assembly 3 ensures the accuracy and consistency of the part marking position, avoiding the position deviation or defects that may be caused by traditional mechanical marking.

[0032] In practical application, the bottom marking stamping die is particularly suitable for large parts that require efficient production. Through the die, marking can be directly completed after the stamping process, reducing the production cycle, improving the production efficiency, and reducing the production cost and equipment investment by reducing the process and manual intervention.

[0033] It can be understood that the bottom marking stamping die provided by the embodiment significantly improves production efficiency, reduces operation complexity and production cost through innovative design and optimized workflow, and also provides high-precision and high-consistency marking effect, which is a highly efficient and environmentally friendly die design scheme with wide application prospect.

[0034] Although exemplary embodiments of the present disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the protection scope of the present disclosure defined by the claims. The present disclosure is limited by the additional claims, and the equivalents of these claims are also included.
