Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing technology, and in particular relates to a sheet metal stamping and forming equipment for automotive parts manufacturing. Background Technology

[0002] Automotive sheet metal refers to metal or non-metal sheets used to manufacture various structural and functional parts for automobiles. It has specific strength, toughness, and formability to meet the performance requirements of automobiles. The reason for using stamping equipment is that it can apply pressure to the sheet metal through molds to cause plastic deformation, efficiently and accurately mass-produce parts with complex shapes and consistent dimensions, while ensuring material utilization and structural strength, which meets the large-scale and high-quality production requirements of the automotive manufacturing industry.

[0003] However, existing stamping equipment makes it difficult to remove the stamped sheet metal during use, resulting in deformation, scratches, and other damage to the sheet metal, thereby reducing the quality of automotive parts production and affecting the efficiency of automotive parts production. Utility Model Content

By setting up a demolding part, it solves the problem that existing stamping and forming equipment is not easy to remove the stamped sheet metal during use, which leads to deformation, scratches and other damage to the sheet metal, thereby reducing the quality of automotive parts production and affecting the efficiency of automotive parts production.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a sheet metal stamping and forming equipment for automotive parts production, comprising a base and support legs fixedly connected to the bottom of the base, and further comprising: a demolding part installed at the bottom of the base; a stamping part installed at the top of the base; the demolding part including a demolding assembly installed at the top of the base; and a mold assembly disposed at the top of the base; the demolding assembly including a trapezoidal groove formed at the bottom of the base, a trapezoidal plate provided at the bottom of the base, the top of the trapezoidal plate extending into the trapezoidal groove, the trapezoidal plate being slidably connected to the trapezoidal groove, and two rectangular holes formed on the trapezoidal plate; a power component is provided on the base; and its... In the middle, two rectangular holes provide guidance. The power component includes two limiting slide grooves opened on the base. A slider is slidably connected in each of the two limiting slide grooves. The slider located on the front side is fixedly connected to the second lower mold, and the slider located on the rear side is fixedly connected to the first lower mold. A drive rod is fixedly connected to the bottom of each of the two sliders. The two drive rods extend into the two rectangular holes respectively and contact the two rectangular holes respectively. A fixed bracket is fixedly connected to the bottom of the base. An electric telescopic rod is fixedly connected to the fixed bracket. The output shaft of the electric telescopic rod is fixedly connected to the trapezoidal plate. The telescopic movement pushes the trapezoidal plate to move, thereby realizing the opening and closing action of the lower mold.

[0007] Furthermore, the stamping part includes a support assembly mounted on top of the base; and a stamping assembly mounted on the support assembly.

[0008] Furthermore, the mold assembly includes a lower mold 1 disposed on the top of the base, the lower mold 1 having two grooves on its front side, a lower mold 2 disposed on the top of the base, and two protrusions fixedly connected to the rear side of the lower mold 2. The two protrusions are respectively adapted to the two grooves to improve the stability of mold splicing, thereby ensuring the stability of stamping.

[0009] Furthermore, the support assembly includes several support rods fixedly connected to the top of the base, a fixed plate fixedly connected to the top of the support rods, a movable plate slidably connected to the support rods, and an upper mold fixedly connected to the bottom of the movable plate; wherein, four support rods are provided, and the upper mold is adapted to the lower mold one and the lower mold two to ensure that the movable plate moves smoothly, thereby ensuring the stability of the upper mold during stamping.

[0010] Furthermore, the stamping assembly includes a hydraulic cylinder fixedly connected to the top of the fixed plate. The output shaft of the hydraulic cylinder is fixedly connected to a bidirectional hinge block. Two hinge rods are hinged on the bidirectional hinge block, and hinge elements are provided on the two hinge rods. The output shaft of the hydraulic cylinder passes through the fixed plate and is slidably connected. The bidirectional hinge block is located below the fixed plate. The hinge elements include two connecting rods respectively hinged to the two hinge rods. Two hinge blocks are fixedly connected to the bottom of the fixed plate and the top of the movable plate. Several hinge blocks are respectively hinged to several connecting rods. Several hinge blocks are located between the fixed plate and the movable plate to provide power for the stamping of the upper die.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up a demolding section, the electric telescopic rod is activated to push the trapezoidal plate to the left, causing the two drive rods to drive the slider and the corresponding lower mold one and lower mold two to move closer to each other. After the protrusion and groove are spliced, the plate is placed for stamping. When unloading, the reverse rotation is used to move the two molds away from each other, and the stamped plate can be taken out. This reduces the difficulty and labor intensity of manual demolding, improves demolding efficiency, and reduces the risk of deformation, scratches and other damage to the plate due to improper force during demolding. It protects the integrity and surface quality of the stamped plate.

[0013] 2. By setting up a stamping section, during stamping, the hydraulic cylinder is activated to push the bidirectional hinge block downward, which drives the two hinge rods to move, causing the two hinge rods to rotate on the corresponding connecting rods and move away from each other. This, in turn, squeezes several connecting rods, causing them to rotate on the hinge block and move away from each other, pushing the moving plate down along several parallel support rods, and driving the upper die to stamp the sheet metal. The reverse operation drives the upper die away from the lower die, avoiding local stress concentration, reducing uneven deformation of the sheet metal and die wear, extending die life, ensuring uniform stamping pressure, and improving stamping quality.

[0028] A specific application of this embodiment is as follows: During use, the electric telescopic rod 218 is activated. The electric telescopic rod 218 pushes the trapezoidal plate 212 to the left within the trapezoidal slide groove 211. At this time, the trapezoidal plate 212, through two rectangular holes 213, causes the two drive rods 216 to move closer together. The two drive rods 216 then drive the two sliders 215 to slide and move closer together within corresponding limit slide grooves 214. The two sliders 215 then drive the lower mold 1 221 and the lower mold 223 to move closer together. The lower mold 223 is then joined by two protrusions 224 and two grooves 222 on the lower mold 1 221. The sheet metal is then placed on the lower mold 1 221 and the lower mold 223 for stamping. Through the reverse operation process, the lower mold 1 221 and the lower mold 223 are moved away from each other, thus removing the stamped sheet metal. During stamping, the hydraulic cylinder 321 is activated, which pushes the bidirectional hinge block 322 downward. The bidirectional hinge block 322 then moves the two hinge rods 323. The two hinge rods 323 rotate on their respective connecting rods 324 and move away from each other. The two connecting rods 324 then press against their respective connecting rods 324, causing several connecting rods 324 to rotate on their respective hinge blocks 325 and move away from each other. This pushes the moving plate 313 to slide downward on several support rods 311. The parallel design of the support rods 311 ensures the smooth movement of the moving plate 313. The moving plate 313 then drives the upper mold 314 to stamp the sheet metal. Through the reverse operation process, the upper mold 314 moves away from the lower mold 1 221 and the lower mold 2 223.
