Description

Technical Field

[0001] This utility model relates to the field of stamping die equipment technology, and in particular to a precision die structure for high-speed stamping. Background Technology

[0002] Precision die structures for high-speed stamping mainly include two-plate dies, drawer dies (modular dies), and three-plate dies (also known as eight-plate dies). These die structures are widely used in electronics, automotive, optics, industrial control, and medical fields. Regardless of the structure, the working principle and functional structure of the die are the same: driving the relative movement of the die parts and acting on the material being stamped to complete processes such as punching / bending, separation, or plastic deformation. Precision die structures for high-speed stamping have broad application prospects in multiple fields, and with continuous technological innovation and development, their application areas will be further expanded and deepened.

[0003] In existing technologies, there are many types of high-speed stamping precision dies, including blanking dies, drawing dies, and other forms. In actual production, different dies are often needed to adapt to diverse production needs, depending on the characteristics of the products to be produced and the process requirements. However, to ensure the service life of each die and its stability and precision during production, different types of dies often employ their own specific fixing methods. For example, blanking dies are usually designed with a concave shape and are fastened with screws; while drawing dies have a convex structure and require bottom supports or special clamps for stable installation. Although this diverse fixing method can provide the best solution for the characteristics of each die, it is not without its challenges. However, this also brings about problems in equipment adaptability: the same high-speed stamping press is difficult to quickly and easily adapt to all types of mold replacement needs. In addition, during high-speed stamping, due to the large and frequent impact force, coupled with the heat accumulation generated by friction, if an unsuitable mold fixing method is used, it can easily lead to mold displacement or even damage, which in turn affects the precision control of the entire processing process. For example, when an improper fixing method is used, the mold may move slightly after being subjected to a strong impact, or the material properties may change due to local overheating, ultimately causing problems such as increased dimensional deviation of finished products and decreased surface quality, thereby reducing the product qualification rate. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a precision die structure for high-speed stamping.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a precision mold structure for high-speed stamping, comprising a stamping equipment and a stamping mold, wherein the bottom of the stamping mold is provided with a bottom retaining groove, the inner wall of the stamping equipment is provided with a horizontal circular groove, a top column is fixed to the top of the stamping equipment, and both the inner wall of the top column and the inner wall of the stamping equipment are provided with vertical circular grooves, a vertical moving rod is slidably connected to the inner wall of the vertical circular groove, a cylindrical groove is provided at the top of the vertical moving rod, a fixing cap is fixed at the top of the inner wall of the vertical circular groove, a return spring is fixed at the bottom of the fixing cap, the bottom of the return spring is fixed to the bottom of the inner wall of the cylindrical groove, a column groove is provided in the middle of the vertical moving rod and the bottom of the top column, a pressure fixing rod is rotatably connected to the inner wall of the column groove, an inclined groove is provided at the bottom of the vertical moving rod, an inclined surface is slidably connected to the inner wall of the inclined groove, a push rod is fixed to one end of the inclined surface, the circumference of the push rod is slidably connected to the inner wall of the horizontal circular groove, and the push rod is driven by a driving cylinder.

[0006] Preferably, the stamping die has limited stepped grooves on both sides, and stepped slides are fixed on both sides of the inner wall of the stamping equipment. The surface of the stepped slides is slidably connected to the inner wall of the limited stepped grooves. In the prior art, stamping dies usually have a large volume and weight, which significantly increases the difficulty of operation during installation. Once shaking occurs during the installation or adjustment stage, due to inertia, it is difficult to quickly and accurately control the movement trajectory of such heavy dies, which can easily lead to accidental collisions with the inner wall of the stamping equipment. Such collisions not only damage the die itself, but more seriously, they cause scratches, dents, or other forms of wear to the inner wall of the equipment, thereby affecting the overall accuracy and operating efficiency of the equipment. In addition, if the stamping die is not securely fixed in place at the start of production, i.e. Even slight lateral vibrations can be amplified under the repeated action of high-speed stamping. This continuous vibration can cause abnormal wear on the components between the mold and the equipment. For example, key components such as guide columns, fixing fixtures, and even stamping heads suffer unnecessary damage. Over time, this wear will gradually accumulate, eventually leading to a significant reduction in the service life of the equipment, increasing maintenance costs and downtime, and posing a direct threat to the production efficiency and economic benefits of the enterprise. To address this problem, this utility model adopts a ladder slide installation method. When the operator installs the stamping mold on the stamping equipment, the ladder groove is aligned with the ladder slide and slid in, thereby preventing shaking during installation and shaking and wear during production, thus improving the service life of the equipment.

[0007] Preferably, the stamping die has arc-shaped grooves on both sides of its bottom end, and a spring arc plate is fixed to one bottom end of the trapezoidal slide. In the prior art, during the installation of stamping dies, workers face a significant challenge: it is difficult to quickly and accurately determine whether the die has been correctly and properly installed on the stamping equipment. This problem stems from several aspects. First, the physical characteristics of heavy dies make manual adjustment and confirmation of their position extremely difficult. Second, minute gaps or imperfections between the die and the equipment contact surface are not easily detected by the naked eye, but can significantly affect subsequent production quality. Furthermore, there is a lack of intuitive and effective auxiliary tools or indicator systems. This increases the difficulty of judgment, directly leading to a decrease in work efficiency. In addition, if improperly installed molds are not detected and corrected in time, once put into production, they will cause a chain reaction such as increased product defect rate and equipment damage, further aggravating the loss of production efficiency and increased costs. To address these problems, this utility model adopts the method of installing spring arc plates. When the worker installs the stamping mold, once the arc groove of the stamping mold reaches the spring arc plate, the spring arc plate quickly releases elastic potential energy and embeds into the arc groove, fixing the stamping mold. At the same time, it provides feedback to the worker, reminding them to install it correctly, thereby improving work efficiency.

[0008] Preferably, the bottom of the stamping die is provided with a positioning groove, and the top of the stamping equipment is fixed with a positioning pin. The positioning pin and the positioning groove cooperate to further ensure the accuracy of installation and improve the stability of equipment use.

[0009] Preferably, a rectangular groove is formed at one end of the inner wall of the horizontal circular groove, and a limiting end is slidably connected to the inner wall of the rectangular groove. One end of the limiting end is fixed to one end of the inclined surface component, thereby limiting the movement trajectory of the component and improving the stability of the equipment.

[0010] Preferably, the stamping equipment has a side sinking groove on its side, and a drive cylinder is fixed to the inner wall of the side sinking groove, which ensures that the drive cylinder does not rise above the surface of the equipment, preventing collisions during use and thus improving the service life of the equipment.

[0011] Preferably, the bottom of the stamping equipment is fixed with a rubber pad, which reduces equipment vibration and noise, thereby improving the user experience.

[0012] Beneficial effects:

[0013] 1. In existing technologies, there are many types of high-speed stamping precision dies, including blanking dies, drawing dies, and other forms. In actual production, different dies are often needed to adapt to diverse production needs, depending on the characteristics of the products to be produced and the process requirements. However, to ensure the service life of each die and its stability and precision during production, different types of dies often adopt their own specific fixing methods. For example, blanking dies are usually designed with a concave shape and are fastened with screws; while drawing dies have a convex structure and require bottom support or special clamps for stable installation. Although this diverse fixing method can provide the best solution for the characteristics of each die, it also brings problems in equipment adaptability: that is, the same high-speed stamping press cannot quickly and easily adapt to the changing needs of all types of dies. In addition, during high-speed stamping, due to the large and frequent impact force, coupled with the heat accumulation generated by friction, if a die fixing method unsuitable for the current working conditions is used, it is easy for the die to shift or even be damaged, thus affecting the precision control of the entire processing process. For example, when an improper fixing method is used, the die may be subjected to... After a strong impact, slight movement may occur, or changes in material properties may occur due to localized overheating, ultimately leading to increased dimensional deviations and decreased surface quality in the finished product, thus reducing the product qualification rate. To address these issues, this invention employs a pressing and fixing swivel rod installation method. Before production begins, the worker slides the stamping die into the stamping equipment, then activates the drive cylinder to move the push rod to one end. This causes the inclined piece, in cooperation with the inclined groove, to push the vertical rod upwards. The vertical rod's central groove pushes one end of the pressing and fixing swivel rod upwards. The pressing and fixing swivel rod rotates around its rotating connection with the top column, causing... The other end of the pressure-fixing rod presses against the inner wall of the bottom retaining groove of the stamping die, thus fixing the stamping die to the stamping equipment. This also effectively limits the up-and-down movement of the die, reducing wear. Furthermore, the clamping point is well-suited for hollow blanking dies, preventing deformation, and meets the bottom fixing requirements of deep drawing dies. When the operator needs to change the die, the drive cylinder is activated again to pull the push rod back. Simultaneously, the return spring releases its elastic potential energy to reset the vertical rod, and the pressure-fixing rod rotates in the opposite direction to release the fixation. This facilitates die replacement, improving user experience and expanding the equipment's application range.

[0014] 2. In existing technologies, stamping dies typically have a large volume and weight, which significantly increases the difficulty of operation during installation. If any shaking occurs during installation or adjustment, the inertia makes it difficult to quickly and accurately control the movement trajectory of such heavy dies, making them highly susceptible to accidental collisions with the inner wall of the stamping equipment. Such collisions not only damage the die itself but, more seriously, cause scratches, dents, or other forms of wear on the inner wall of the equipment, thus affecting the overall precision and operating efficiency of the equipment. Furthermore, if the stamping die is not securely fixed in place at the start of production, even slight lateral vibrations will be amplified under the repeated action of high-speed stamping. The continuous vibration can cause abnormal wear on the components between the mold and the equipment. For example, key components such as guide columns, fixing fixtures, and even stamping heads suffer unnecessary damage. Over time, this wear will gradually accumulate, eventually leading to a significant reduction in the service life of the equipment, increasing maintenance costs and downtime, and posing a direct threat to the production efficiency and economic benefits of enterprises. To address this problem, this utility model adopts the method of installing a ladder slide. When the operator installs the stamping mold on the stamping equipment, the ladder groove is aligned with the ladder slide and slid in, thereby preventing shaking during the installation process and shaking and wear during the production process, thus improving the service life of the equipment.

[0015] 3. In the existing technology, during the installation of stamping dies, workers face a significant challenge: it is difficult to quickly and accurately determine whether the die has been correctly and properly installed on the stamping equipment. This problem stems from several aspects. First, the physical characteristics of heavy dies make manual adjustment and confirmation of their position extremely difficult. Second, minute gaps or incomplete matching between the die and the equipment contact surface are not easily detected by the naked eye, but are enough to affect subsequent production quality. Third, the lack of intuitive and effective auxiliary tools or indicator systems increases the difficulty of judgment, directly leading to a decrease in work efficiency. In addition, if improperly installed dies are not detected and corrected in time, once put into production, they will cause a chain reaction such as increased product defect rate and equipment damage, further exacerbating the loss of production efficiency and increased costs. To address these problems, this utility model adopts the method of installing spring arc plates. When workers install stamping dies, once the arc groove of the stamping die reaches the spring arc plate, the spring arc plate quickly releases elastic potential energy and embeds into the arc groove, fixing the stamping die. At the same time, it provides feedback to workers, indicating that the installation is in place, thereby improving work efficiency. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0025] Reference Figure 1-4A precision die structure for high-speed stamping includes a stamping equipment 1 and a stamping die 101. The stamping die 101 has a bottom retaining groove 102 at its bottom. A horizontal circular groove 201 is formed on the inner wall of the stamping equipment 1. A top post 205 is fixed to the top of the stamping equipment 1. Both the inner wall of the top post 205 and the inner wall of the stamping equipment 1 have vertical circular grooves 204. A vertical rod 209 is slidably connected to the inner wall of the vertical circular groove 204. The top of the vertical rod 209 has a cylindrical groove. A fixing cap 206 is fixed to the top of the inner wall of the vertical circular groove 204. A return spring 207 is fixed to the bottom of the cap 206. The bottom of the return spring 207 is fixed to the bottom of the inner wall of the cylindrical groove. A column groove 208 is opened in the middle of the vertical rod 209 and the bottom of the top column 205. A pressure rod 2010 is rotatably connected to the inner wall of the column groove 208. An inclined groove is opened at the bottom of the vertical rod 209. An inclined surface 203 is slidably connected to the inner wall of the inclined groove. A push rod 202 is fixed at one end of the inclined surface 203. The circumference of the push rod 202 is slidably connected to the inner wall of the horizontal circular groove 201. The push rod 202 is driven by the drive cylinder 2. The stamping die 101 has limited ladder grooves 3 on both sides, and ladder slides 301 are fixed on both sides of the inner wall of the stamping equipment 1. The surface of the ladder slides 301 is slidably connected to the inner wall of the limited ladder grooves 3. The stamping die 101 usually has a large volume and weight, which significantly increases the difficulty of operation during the installation process. Once shaking occurs during the installation or adjustment stage, due to inertia, it is difficult to quickly and accurately control the movement trajectory of this heavy die, which makes it very easy to accidentally collide with the inner wall of the stamping equipment 1. Such collisions not only damage the die itself, but more seriously, they cause scratches, dents or other forms of wear to the inner wall of the equipment, thereby affecting the overall accuracy and operating efficiency of the equipment. In addition, if the stamping die 101 is not firmly fixed in place at the start of production, Even slight lateral vibrations can be amplified under the repeated action of high-speed stamping. This continuous vibration can cause abnormal wear on the components between the mold and the equipment. For example, key components such as guide columns, fixing fixtures, and even stamping heads suffer unnecessary damage. Over time, this wear will gradually accumulate, eventually leading to a significant reduction in the service life of the equipment, increasing maintenance costs and downtime, and posing a direct threat to the company's production efficiency and economic benefits. The solution is to install a ladder slide 301. When the operator installs the stamping mold 101 into the stamping equipment 1, the ladder groove 3 is aligned with the ladder slide 301 and slid in, thereby preventing shaking during installation and shaking and wear during production, thus improving the service life of the equipment.

[0026] Both sides of the bottom end of the stamping die 101 are provided with arc-shaped grooves 4, and a spring arc plate 401 is fixed to one bottom end of the ladder slide 301. During the installation of the stamping die 101, the workers face a significant challenge: it is difficult to quickly and accurately determine whether the die has been correctly and properly installed on the stamping equipment 1. This problem mainly stems from several aspects. First, the physical characteristics of the heavy die make manual adjustment and confirmation of its position extremely difficult. Second, the tiny gaps or incomplete matching between the die and the equipment contact surface are not easily detected by the naked eye, but are enough to affect the subsequent production quality. Third, the lack of intuitive and effective auxiliary tools or indicator systems increases the difficulty of judgment. The difficulty of installation directly leads to a decrease in work efficiency. Furthermore, if improperly installed molds are not detected and corrected in time, they can cause a chain reaction of increased product defect rates and equipment damage once put into production, further exacerbating the loss of production efficiency and increased costs. This is solved by installing a spring-loaded arc plate 401. When the worker installs the stamping die 101, once the arc groove 4 of the stamping die 101 reaches the spring-loaded arc plate 401, the spring-loaded arc plate 401 quickly releases its elastic potential energy and embeds itself into the arc groove 4, fixing the stamping die 101 in place. Simultaneously, it provides feedback to the worker, indicating that the installation is correct, thus improving work efficiency. A positioning groove 5 is provided at the bottom of the stamping die 101, and a positioning pin 501 is fixed at the top of the stamping equipment 1. The cooperation between the positioning pin 501 and the positioning groove 5 further ensures the accuracy of installation, thereby improving the stability of equipment use. A rectangular groove 6 is formed at one end of the inner wall of the horizontal circular groove 201. A limiting end 601 is slidably connected to the inner wall of the rectangular groove 6. One end of the limiting end 601 is fixed to one end of the inclined surface 203, thereby limiting the movement trajectory of the components and improving the stability of the equipment. A side sinking groove 7 is formed on the side of the stamping equipment 1. A drive cylinder 2 is fixed to the inner wall of the side sinking groove 7, ensuring that the drive cylinder 2 does not exceed the surface of the equipment, preventing collisions during use and extending the service life of the equipment. A rubber pad is fixed to the bottom of the stamping equipment 1 to reduce equipment vibration and noise, thereby improving the user experience.

[0027] The working principle of this utility model is as follows: Before production begins, the operator slides the stamping die 101 into the stamping equipment 1. Then, the drive cylinder 2 is activated, causing the push rod 202 to move to one end. This causes the inclined surface 203 to move upward by cooperating with the inclined groove, pushing the vertical rod 209 upward. The vertical rod 209 pushes one end of the pressing and fixing rod 2010 upward at the column groove 208. The pressing and fixing rod 2010 rotates about the rotational connection with the top column 205 as an axis, so that the other end of the pressing and fixing rod 2010 presses against the bottom retaining groove 102 of the stamping die 101. At the wall, the stamping die 101 and the stamping equipment 1 are fixed by clamping, which can effectively limit the up and down shaking of the die and reduce its wear. At the same time, the clamping point can be well adapted to the hollow blanking die to prevent its deformation and can meet the bottom fixing requirements of the deep drawing die. When the operator needs to change the die, the drive cylinder 2 is started again to pull back the push rod 202. At the same time, the return spring 207 releases the elastic potential energy to reset the vertical rod 209, and the pressing and fixing rod 2010 rotates in the opposite direction to release the fixation, which makes it convenient for the operator to change the die.
