Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a metal stamping die. Background Art

[0002] Strip stamping is crucial in the metal processing industry and is widely used in the process of manufacturing metal parts. Strips are continuous rolls of metal sheets. In actual production, metal strips are very susceptible to the impact of factors such as die shape, pressure distribution, and stamping speed during the stamping process due to their softness, causing springback, making it difficult to control the dimensional accuracy of the final parts. This springback phenomenon is particularly evident in the processing of complex-shaped parts, directly affecting the assembly performance and interchangeability of the product. At the same time, it may also cause damage to the die, increasing production costs and maintenance difficulties.

[0003] In the existing production process, the real-time monitoring of strip status and fault warning mechanism are still imperfect. Most production lines rely on finished product inspection to identify problems. This lag leads to a large waste of resources, including materials, time and money. In addition, mold design and maintenance are also a major challenge. Mold wear and life management directly affect production efficiency and product quality, and traditional mold design often fails to fully consider the dynamic response of materials and nonlinear factors in the processing process.

The metal strips are fed from one side of the discharge end of a feeding mechanism, and comprise a main body, a discharge port, and a sensor assembly. The main body is arranged at the discharge end of the feeding mechanism, and the main body comprises an opening, and the opening corresponds to the discharge end; the discharge port is arranged on a side of the main body away from the opening, and the strip after stamping is separated from the main body through the discharge port; the assembly is arranged outside the opening, and the sensor assembly is arranged on a straight line where a line connecting the opening and the discharge port is located.

[0005] Preferably, the opening and the discharge port are arranged horizontally, and the sensor component is arranged on the side close to the discharge end.

[0006] Preferably, the sensor component is a photoelectric sensor.

[0007] Preferably, the body comprises a mold cavity, and the cavity is provided with an inner groove coupled with the shape of the cavity.

[0008] Preferably, the inner groove is plugged into the cavity, and the inner groove and the cavity are detachable.

[0009] Preferably, the sensor assembly is in contact with the inner groove, and the sensor assembly includes a strain sensor and a displacement sensor.

[0010] According to the metal stamping die of the embodiment of the utility model, by arranging the sensor component on the outside of the opening of the die body, real-time status monitoring and abnormal feedback of the metal strip stamping process are realized, which significantly improves the production efficiency and the degree of automation, and at the same time enhances the flexibility and maintainability of the die. The connecting lines are on the same straight line, and the principle of light can be used to realize detection. Compared with the internal integrated sensor, the cost is lower, thereby achieving the effect of improving product quality and reducing production costs.

[0011] It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the technology as claimed. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the structure of a metal stamping die according to an embodiment of the utility model. DETAILED DESCRIPTION

[0013] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0014] First, combine Figure 1 Description The metal stamping die according to the embodiment of the utility model is widely used in scenes such as metal stamping forming, high-precision metal processing, etc. In this embodiment, a rolled metal sheet is taken as an example for description.

[0015] like Figure 1 As shown, the metal stamping die of the embodiment of the utility model is used to process a metal strip 1 , which is fed from the discharge end 21 of a feeding mechanism 2 , and has a body 3 , a discharge port 32 and a sensor assembly 4 .

[0016] Specifically, Figure 1 As shown, the main body 3 is arranged at the discharge end 21 of the feeding mechanism 2, and the main body 3 includes an opening 31, and the opening 31 corresponds to the discharge end 21; the discharge port 32 is arranged on the side of the main body 3 away from the opening 31, and the strip 1 after stamping is separated from the main body 3 through the discharge port 32; the component is arranged outside the opening 31, which simplifies the structural design of the mold and makes the installation and debugging of the sensor component 4 more convenient. The sensor component 4 is arranged on the straight line where the opening 31 and the discharge port 32 are connected. The lines are on the same straight line, and the principle of light can be used to achieve detection. Compared with internal integrated sensors, the cost is lower, thereby achieving the effect of improving product quality and reducing production costs.

[0017] Preferably, if Figure 1As shown, the opening 31 and the discharge port 32 are arranged horizontally, which is conducive to maintaining the stability of the strip 1 during the conveying process, reducing errors caused by tilting or vibration, and further improving the detection accuracy. The sensor component 4 is arranged on the side close to the discharge end 21, and the side close to the discharge end 21 can detect the abnormality of the strip 1 in the process of entering the mold, such as bending, deviation, etc., earlier, thereby improving the timeliness and accuracy of the detection.

[0018] Preferably, if Figure 1 As shown, the sensor assembly 4 is a photoelectric sensor, which is used as the main detection means to quickly and accurately identify the position, speed, and whether there are abnormal conditions such as breakage and bending of the strip 1. The photoelectric sensor has the advantage of non-contact measurement, reduces wear and error caused by mechanical contact, and improves the reliability and service life of the system.

[0019] Preferably, the main body 3 includes a mold cavity (not shown in the figure), and the cavity is provided with an inner groove (not shown in the figure) coupled with the shape of the cavity. A detachable connection is adopted between the mold cavity and the inner groove, so that maintenance and replacement of the mold become more convenient, and even if there is a deformation problem, it will not cause damage to the entire mold.

[0020] Preferably, the inner groove is connected to the cavity, and the inner groove and the cavity are detachable. When it is necessary to replace a mold of a different specification or to clean the interior, it is only necessary to simply disassemble the inner groove, which greatly saves time and labor costs.

[0021] Preferably, the sensor assembly 4 is in contact with the inner groove, and the sensor assembly 4 includes a strain sensor and a displacement sensor. The deformation and displacement of the strip 1 during the stamping process can be monitored simultaneously. These two sensors provide more comprehensive data support, which helps to more accurately judge the stamping quality of the strip 1.

[0022] When in use, the sensor is precisely installed on the outside of the mold opening 31, located on the path that the strip 1 must take to enter the mold, to ensure that the state of the strip 1 can be sensed in real time. When the strip 1 passes through the sensor, if there are abnormal conditions such as bending or deformation on its surface or inside, the sensor will immediately capture these changes and send the corresponding signal to the control system. After receiving the signal from the sensor, the control system will quickly process and analyze the data to determine whether the degree of deformation of the strip 1 exceeds the preset safety range. Once the abnormality is confirmed, the control system will immediately trigger the alarm mechanism and send a clear warning message to the operator through sound, light or display screen, indicating that the state of the strip 1 is abnormal. According to the feedback from the control system, the operator can immediately take corresponding measures, such as adjusting the stamping parameters, suspending production for inspection, or replacing qualified strip 1, so as to avoid the expansion of the problem, reduce material waste, and ensure the smooth progress of the subsequent production process.

[0023] Above, refer to Figure 1 A metal stamping die according to an embodiment of the utility model is described, in which a sensor component 4 can be arranged on the outside of the opening 31 of the die body 3, thereby realizing real-time status monitoring and abnormal feedback of the stamping process of the metal strip 1, significantly improving production efficiency and the degree of automation, while enhancing the flexibility and maintainability of the die. The connecting lines are on the same straight line, and detection can be achieved using the principle of light. Compared with internal integrated sensors, the cost is lower, thereby achieving the effect of improving product quality and reducing production costs.
