Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing and processing, in particular to a pressure rod crossbeam forming mold. Background Art

[0002] In the metal processing and forming industry, stamping die forming is a common process used to manufacture various metal parts and components, such as automobile body structures, industrial machinery parts, etc. The press beam forming die is the key tool in this process. It is usually composed of upper die, lower die and machine tool parts, and it molds the metal material into the desired shape, such as curves, convexities, etc. by applying pressure.

[0003] However, there are some problems with traditional stamping dies, mainly including the following aspects:

[0004] 1. Low production efficiency: The bottom of the traditional stamping die is generally fixed directly on the machine tool by bolts and nuts. Adjusting and replacing the die is time-consuming and labor-intensive, resulting in low production efficiency and limiting the improvement of production capacity.

[0005] 2. Unstable product quality: In the process of traditional stamping die pressing down to stretch the metal, due to the excessive impact force of the upper die, this usually causes the metal material to produce plastic deformation, uneven stretching and other drawing defects, resulting in product shape distortion or unstable size.

[0006] 3. Short mold life: Due to the pressure applied and the high strength of metal materials, traditional stamping molds are susceptible to wear and damage, have a limited service life, and require frequent replacement and maintenance, which increases production costs.

[0007] In summary, the traditional stamping forming dies have a series of limitations and problems, which need to be continuously improved and optimized to improve production efficiency, stabilize product quality, extend the service life of the dies, etc. Therefore, we designed a press rod crossbeam forming die to solve the problems of the existing technology. Utility Model Content

[0008] The technical problem to be solved by the utility model is to solve the deficiencies of the above-mentioned prior art and provide a pressure rod crossbeam forming die.

[0009] In order to solve the above technical problems, the utility model adopts the following technical solutions: a pressure rod beam forming mold, including an upper mold, a lower mold and a buffer plate, the upper mold and the lower mold are placed along the height direction, the upper mold is a concave mold, the lower mold is a convex mold, the upper mold is located above the lower mold, and a mold cavity is formed between the upper mold and the lower mold. The buffer plate is located above the lower mold, and a buffer component is provided between the buffer plate and the lower mold, and the buffer component can drive the buffer plate to move toward or away from the lower mold.

[0010] Compared with the problems of unstable product quality and short mold life in the prior art, the technical principle and technical effect of this solution are as follows: during operation, the upper mold exerts downward pressure to gradually fill the raw materials or semi-finished products into the mold cavity, and obtains the required shape and size according to the design shape of the mold; during the downward pressure of the upper mold, the upper mold first contacts the buffer plate. At this time, the buffer plate will absorb part of the impact energy to avoid the impact caused by the sudden contact of the upper mold with the lower mold, thereby reducing the risk of damage to the mold and the workpiece. The buffer plate can also adjust the stretching speed of the metal material during this process to avoid problems such as uneven stretching or excessive stretching caused by too fast or too slow stretching speed. At the same time, the buffer plate also provides smoother pressure transfer during this process, thereby improving the precision and quality of material forming.

[0011] Furthermore, the buffer component is four spring columns, which are located at the four corners of the buffer plate. The top ends of the spring columns are connected to the buffer plate. The lower mold is provided with four grooves corresponding to the spring columns. The spring columns extend into the grooves. A spring is provided in the groove. One end of the spring is connected to the bottom of the groove, and the other end is connected to the spring column.

[0012] The technical principle and technical effect of this solution are: when the buffer plate is under pressure, the buffer plate transfers the pressure to the spring through the spring column, and the spring deforms downward and absorbs and transfers the stress through its own elasticity; when the pressure on the buffer plate disappears, the spring returns to its original state through its own elasticity, and in the process provides supporting force to the buffer plate through the spring column, so that the buffer plate returns to its original position.

[0013] Furthermore, it also includes a base, which is located at the bottom of the lower mold and is used to support the lower mold.

[0014] The technical principle and technical effect of this solution are: the base provides support for the lower die, which helps to reduce the vibration and deformation of the lower die during operation and improves the stability and accuracy of processing.

[0015] Furthermore, it also includes a grid platform and a fastening component, the grid platform is fixed to the outside of the base, the grid platform is radially opened with a plurality of strip-shaped grooves, the fastening component includes a pressure plate, a threaded column and a fixing column, one end of the threaded column is fixed in the groove of the grid platform, and the other end is provided with a threaded groove, one end of the fixing column is provided with a square iron sheet, the square iron sheet is located on the upper surface of the grid platform, the other end of the fixing column is connected to the pressure plate, the pressure plate extends to the upper surface of the lower mold, and is used to fix the lower mold, the pressure plate is provided with an opening for the threaded column to pass through, the threaded column passes through the opening and is threadedly connected to the bolt and fixed to the pressure plate.

[0016] With respect to the problem of low production efficiency existing in the prior art, the technical principle and technical effect of the present scheme are as follows: the fastening component is used to fix the position of the pressure plate, and the pressure plate is used to fix the position of the lower mold. The installation method of the fastening component will cause the pressure plate to exert a downward pressure on the lower mold. When the lower mold is subjected to the pressure of the upper mold and is about to move, the pressure of the pressure plate on the lower mold will increase the friction between the pressure plate and the lower mold, preventing the movement of the lower mold and thus playing a role in fixing the position of the lower mold. When the lower mold is replaced, the combination of the fastening components is disassembled, and the pressure plate fixing the lower mold is removed and the lower mold can be replaced. The design of the grid table and the fastening components makes the mold more flexible and can adapt to different production needs and product specifications, reducing production downtime and improving production efficiency.

[0017] Furthermore, it also includes two limiting columns, which are arranged diagonally between the lower mold and the upper mold.

[0018] The technical principle and technical effect of this solution are as follows: the limit column ensures the precise alignment of the upper and lower dies when the upper die is pressed down to facilitate stamping processing. The limit column also plays a certain supporting role, so that the mold remains stable during operation without offset or vibration. The accurate positioning and stable support of the limit column can ensure the accuracy and stability of the upper die during the pressing process, thereby improving the accuracy and product quality of the stamping process. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is the front view of the utility model. DETAILED DESCRIPTION

[0020] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0021] The reference numerals in the drawings of the specification include: upper die 1, limiting column 2, threaded column 3, buffer plate 4, pressure plate 5, fixed column 6, lower die 7, spring column 8, grid platform 9, spring 10, base 11.

[0022] See also Figure 1 As shown, the installation method of the pressure rod beam forming mold in the embodiment includes an upper mold 1, a lower mold 7 and a buffer plate 4. The upper mold 1 and the lower mold 7 are placed along the height direction. The upper mold 1 is a concave mold, and the lower mold 7 is a convex mold. The upper mold 1 is located above the lower mold 7. A mold cavity is formed between the upper mold 1 and the lower mold 7. The buffer plate 4 is located above the lower mold 7. A buffer component is provided between the buffer plate 4 and the lower mold 7. The buffer component can drive the buffer plate 4 to move toward or away from the lower mold 7.

[0023] During operation, the upper mold 1 applies downward pressure to gradually fill the raw materials or semi-finished products into the mold cavity, and obtain the required shape and size according to the design shape of the mold; during the downward pressure of the upper mold 1, the upper mold 1 first contacts the buffer plate 4. At this time, the buffer plate 4 will absorb part of the impact energy to avoid the impact caused by the upper mold 1 suddenly contacting the lower mold 7, thereby reducing the risk of damage to the mold and the workpiece. The buffer plate 4 can also adjust the stretching speed of the metal material during this process to avoid problems such as uneven stretching or excessive stretching caused by too fast or too slow stretching speed. At the same time, the buffer plate 4 also provides a smoother pressure transfer during this process, thereby improving the accuracy and quality of material forming.

[0024] The buffer components are four spring columns 8, which are located at the four corners of the buffer plate 4. The top ends of the spring columns 8 are connected to the buffer plate 4. The lower mold 7 is provided with four grooves corresponding to the spring columns 8. The spring columns 8 extend into the grooves. A spring 10 is provided in the grooves. One end of the spring 10 is connected to the bottom of the groove, and the other end is connected to the spring column 8.

[0025] When the buffer plate 4 is under pressure, the buffer plate 4 transfers the pressure to the spring 10 through the spring column 8. The spring 10 deforms downward and absorbs and transfers the stress through its own elasticity. When the pressure on the buffer plate 4 disappears, the spring 10 restores its original state through its own elasticity, and in the process provides supporting force to the buffer plate 4 through the spring column 8, so that the buffer plate 4 returns to its original position.

[0026] The pressure rod crossbeam device also includes two limit columns 2, which are diagonally arranged between the lower mold 7 and the upper mold 1. The limit columns 2 ensure the precise alignment of the upper and lower molds 7 when the upper mold 1 is pressed down to facilitate stamping processing. The limit columns 2 also play a certain supporting role, so that the mold remains stable during operation without offset or vibration. The accurate positioning and stable support of the limit columns 2 can ensure the accuracy and stability of the upper mold 1 during the pressing process, thereby improving the accuracy and product quality during the stamping process.

[0027] The pressure rod crossbeam device also includes a base 11, a grid platform 9 and a fastening component. The base 11 is located at the bottom of the lower mold 7 and is used to support the lower mold 7. The grid platform 9 is fixed to the outside of the base 11. The grid platform 9 is radially provided with a plurality of strip-shaped grooves. The fastening component includes a pressure plate 5, a threaded column 3 and a fixing column 6. One end of the threaded column 3 is fixed in the groove of the grid platform 9, and the other end is provided with a threaded groove. One end of the fixing column 6 is provided with a square iron sheet, and the square iron sheet is located on the upper surface of the grid platform 9. The other end of the fixing column 6 is connected to the pressure plate 5. The pressure plate 5 extends to the upper surface of the lower mold 7 and is used to fix the lower mold 7. The pressure plate 5 is provided with an opening for the threaded column 3 to pass through. The threaded column 3 passes through the opening and is threadedly connected to the bolt and fixed on the pressure plate 5.

[0028] The fastening component is used to fix the position of the pressing plate 5, and the pressing plate 5 is used to fix the position of the lower mold 7. The installation method of the fastening component will cause the pressing plate 5 to exert a downward pressure on the lower mold 7. When the lower mold 7 is subjected to the pressure of the upper mold 1 and is about to move, the pressure of the pressing plate 5 on the lower mold 7 will increase the friction between the pressing plate 5 and the lower mold 7, preventing the lower mold 7 from moving, thereby playing a role in fixing the position of the lower mold 7. When the lower mold 7 is replaced, the combination of the fastening components is disassembled, and the pressing plate 5 fixing the lower mold 7 is removed, and the lower mold 7 can be replaced. The design of the grid platform 9 and the fastening component makes the mold more flexible and can adapt to different production needs and product specifications, reducing production downtime and improving production efficiency.
