Description

Technical Field

[0001] This utility model relates to the field of stamping dies, specifically a stamping die for metal stamping parts. Background Technology

[0002] Stamping dies are key tools used in hardware manufacturing to produce metal or non-metal stamped parts. According to their structure, they can be divided into single-engineering dies, compound dies, and progressive dies. A die set usually consists of upper and lower dies, including parts such as die base, clamping plate, punch, and die. Die materials are diverse, such as hot-dip galvanized steel sheet and stainless steel sheet, and their performance can be improved through surface treatment.

[0003] Currently, traditional stamping dies generate waste material during the stamping process. This waste material comes in various shapes, and with existing technology, it is difficult to separate waste materials of different shapes when they are collected in a unified manner. This makes it difficult to sort out waste materials that still have utilization value for reuse. Therefore, the inventors urgently need to design a stamping die that can sort and separate waste materials to improve the reuse rate of waste materials. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a stamping die for metal stamping parts to solve the technical problem that it is difficult to separate waste materials of different shapes, making it difficult to effectively sort and reuse waste materials with reuse value.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for metal stamping parts, including a worktable, a lower die, and an upper die. The lower die has stamping holes. A material distribution mechanism is provided below the worktable, and the material distribution mechanism is longitudinally opposite to the lower die. The material distribution mechanism includes a flow-dividing cone plate, and a plurality of partition plates are provided on the flow-dividing cone plate. The partition plates are placed between adjacent stamping holes of different shapes. A receiving frame with the same number and type of stamping holes is placed below the material distribution mechanism.

[0006] By adopting the above technical solution, a material separation mechanism that is longitudinally opposite to the lower die is set below the worktable, which realizes the initial separation of waste generated by stamping holes of different shapes. The setting of the flow divider cone and several partition plates enables the waste between adjacent stamping holes of different shapes to be effectively separated, avoiding the problem of waste mixing and separation in traditional stamping dies.

[0007] Furthermore, an installation sleeve is installed between several of the partition plates, and an air outlet with the same type and number as the stamping holes is opened on the outer side of the installation sleeve, and the air outlet is opposite to the position of the waste falling trajectory.

[0008] By adopting the above technical solution, sleeves are installed between several partition plates, so that if waste accumulates during the falling process, it can be treated in a targeted manner through the air outlet.

[0009] Furthermore, the mounting sleeve is connected to an external air compressor via an air duct and is electrically connected to a controller to disperse accumulated waste.

[0010] By adopting the above technical solution, the flushing and dispersing of accumulated waste materials becomes more automated and intelligent. When waste materials accumulate in the material distribution mechanism, the controller can detect it in time and start the air compressor to inflate the installation sleeve through the air pipe. The air pressure is used to flush away the accumulated waste materials, avoiding the problems of waste material blockage and failure to fall smoothly into the receiving frame.

[0011] Furthermore, a stamping protrusion corresponding to the shape and number of stamping holes is installed below the upper mold.

[0012] By adopting the above technical solution, the accuracy and stability of the stamping process are ensured. The precise matching of the stamping punch and the stamping hole allows the material to be accurately stamped out according to the predetermined shape and size during the stamping process, thereby improving the quality of the stamped parts.

[0013] Furthermore, a support base is installed below the workbench, and the inner space of the support base is divided by several partition plates to form a waste material guiding cavity, and the cavity is opposite to the position of the corresponding receiving frame.

[0014] By adopting the above technical solution, the waste material can be effectively guided and sorted before falling into the receiving frame. The waste material guiding cavity is positioned opposite to the corresponding receiving frame, ensuring that the waste material can fall accurately into the receiving frame and avoiding the problems of waste material scattering and mixing.

[0015] Furthermore, the lower mold and the upper mold are guided and installed by guide pillars, and the upper part of the upper mold is connected to the telescopic end of the drive mechanism.

[0016] By adopting the above technical solution, precise alignment and stable movement during the stamping process are ensured. The guiding effect of the guide column enables the upper die to accurately descend and rise along the predetermined trajectory during the stamping process, avoiding the degradation of stamped parts quality and die damage caused by die misalignment.

[0017] In summary, the present invention has the following main advantages:

[0018] This invention utilizes a material separation mechanism, employing a diversion cone plate and several partition plates to separate stamping holes of different shapes, achieving initial separation of waste materials. This allows waste materials generated during the stamping process to be effectively distinguished according to their shape and type, avoiding the problem of mixed and difficult-to-separate waste materials in traditional stamping dies. After stamping is completed, the waste materials fall from the stamping holes of the lower die and, guided by the diversion cone plate and partition plates, fall into the corresponding receiving frames, thus realizing the waste material separation operation. At the same time, this material separation method allows reusable waste materials to be directly collected and utilized, improving the recycling rate of waste materials. Through the precise guidance of the material separation mechanism, waste materials of different shapes and types are collected separately in the corresponding receiving frames, facilitating subsequent reuse and sorting work.

[0019] This utility model uses an installation sleeve and an air outlet. The installation sleeve, installed between the partition plates, is connected to an external air compressor via an air guide pipe and electrically connected to a controller. This allows for timely measures to disperse accumulated waste. When waste accumulates in the distribution mechanism for various reasons, the controller can quickly detect and start the air compressor, which inflates the installation sleeve through the air guide pipe. The air outlet on the outside of the installation sleeve is positioned opposite the trajectory of the falling waste. The airflow generated after inflation can disperse the accumulated waste through the air outlet, preventing the waste from clogging the distribution mechanism and ensuring that the waste falls smoothly into the corresponding receiving frame.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example 1:

[0026] A stamping die for metal stamping parts, such as Figure 1-4 As shown, the assembly includes a worktable 1, a lower mold 2, and an upper mold 3. The lower mold 2 has stamping holes 7. A material distribution mechanism 5 is located below the worktable 1, and the material distribution mechanism 5 is longitudinally opposite to the lower mold 2. The material distribution mechanism 5 includes a flow-dividing cone plate 501, on which several partition plates 502 are provided. The partition plates 502 are placed between adjacent stamping holes 7 of different shapes. Below the material distribution mechanism 5, a receiving frame 505, matching the number and type of stamping holes 7, is placed. This is achieved by placing a material distribution mechanism 505 below the worktable 1, longitudinally opposite to the lower mold 2. The material sorting mechanism 5 achieves the initial separation of waste generated from punch holes 7 of different shapes. The setting of the diversion cone plate 501 and several partition plates 502 enables the waste between adjacent punch holes 7 of different shapes to be effectively separated, avoiding the problem of waste mixing and separation in traditional stamping dies. At the same time, the receiving frame 505 placed below the material sorting mechanism 5, which is the same as the number of punch holes 7 of different types, ensures that each type of waste can be collected separately, which is convenient for subsequent reuse and sorting work, improves the recycling rate of waste, and reduces production costs. Example 2:

[0027] See Figure 2 , Figure 3 , Figure 4 A mounting sleeve 503 is installed between several partition plates 502. The outer side of the mounting sleeve 503 has an air outlet 504 with the same number and type as the 7 stamping holes. The air outlet 504 is positioned opposite to the trajectory of the falling waste material. The installation of the mounting sleeve 503 between the partition plates 502 allows the waste material to be treated in a targeted manner through the air outlet 504 if it accumulates during the falling process. At the same time, the position of the air outlet 504 opposite to the trajectory of the falling waste material ensures that the accumulated waste material can be dispersed in time, avoiding the problem of waste material blocking the material distribution mechanism 5. This not only improves the material distribution efficiency but also enhances the stability and reliability of the material distribution mechanism, thus significantly improving the waste material handling capacity of the entire stamping die.

[0028] See Figure 2 , Figure 3 , Figure 4 The mounting sleeve 503 is connected to an external air compressor via an air duct and is electrically connected to the controller to disperse accumulated waste. This makes the dispersion of accumulated waste more automated and intelligent. When waste accumulates in the material distribution mechanism 5, the controller can detect it in time and start the air compressor to inflate the mounting sleeve 503 with air through the air duct. The air pressure disperses the accumulated waste, avoiding the problems of waste blockage and failure to fall smoothly into the receiving frame 505. At the same time, it also reduces the need for manual intervention, reduces labor intensity, and improves production efficiency.

[0029] See Figure 1 , Figure 2 , Figure 3 The upper die 3 is fitted with stamping protrusions 4 that correspond to the shape and number of the stamping holes 7, ensuring the accuracy and stability of the stamping process. The precise matching between the stamping protrusions 4 and the stamping holes 7 allows the material to be accurately stamped out according to the predetermined shape and size during the stamping process, improving the quality of the stamped parts. At the same time, the number of stamping protrusions 4 is consistent with the number of stamping holes 7, ensuring that each stamping hole 7 can be fully stamped, avoiding an increase in the scrap rate due to uneven stamping.

[0030] See Figure 1 , Figure 2 , Figure 3 A support base 6 is installed below the workbench 1. The inner space of the support base 6 is divided by several partition plates 502 to form a waste material guiding cavity. The cavity is positioned opposite to the corresponding receiving frame 505, so that the waste material can be effectively guided and sorted before falling into the receiving frame 505. The position of the waste material guiding cavity opposite to the corresponding receiving frame 505 ensures that the waste material can fall accurately into the receiving frame 505, avoiding the problem of waste material scattering and mixing. At the same time, the setting of the support base 6 also enhances the stability and load-bearing capacity of the entire stamping die, so that the die can maintain stable operation during the stamping process, improving the quality of stamped parts and production efficiency. In addition, the setting of the waste material guiding cavity also facilitates the cleaning and collection of waste material, reducing labor intensity.

[0031] See Figure 1 , Figure 2 , Figure 3 The lower die 2 and the upper die 3 are guided and installed by guide pillars. The upper part of the upper die 3 is connected to the telescopic end of the drive mechanism, which ensures precise alignment and stable movement during the stamping process. The guiding effect of the guide pillars allows the upper die 3 to accurately descend and rise along a predetermined trajectory during the stamping process, avoiding the degradation of stamped parts quality and die damage caused by die misalignment. At the same time, the upper part of the upper die 3 is connected to the telescopic end of the drive mechanism, which allows the stamping action of the die to be precisely controlled by the drive mechanism. This not only improves the automation level of the stamping process, but also allows the stamping parameters to be precisely adjusted according to actual needs, further improving the quality of stamped parts and production efficiency.

[0032] The implementation principle of this embodiment is as follows: By setting a material distribution mechanism 5 under the workbench 1 that is longitudinally opposite to the lower mold 2, the different shaped punching holes 7 are separated by the diversion cone plate 501 and several partition plates 502 to achieve the initial separation of waste materials. After the punching is completed, the waste materials fall from the punching holes 7 of the lower mold 2 and are guided by the diversion cone plate 501 and partition plates 502 to fall into the corresponding receiving frames 505, thereby realizing the waste material distribution operation. Reusable waste materials can be directly used. At the same time, the installation sleeve 503 installed between the partition plates 502 is connected to an external air compressor through an air guide pipe and is electrically connected to the controller. When waste materials accumulate, they can be dispersed through the air outlet 504 to prevent blockage.
