Description

Technical Field

[0001] This utility model relates to the field of stamping die technology for processing automotive body sheet metal parts, specifically a stamping die for processing automotive body sheet metal parts. Background Technology

[0002] Automotive body sheet metal parts refer to the metal outer shell and internal structural components of a car body, typically made from thin metal sheets through processes such as stamping, welding, and bending. These parts not only constitute the car's appearance but also serve to protect the occupants and internal components.

[0003] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Currently, stamping dies serve the purpose of processing materials into parts.

[0004] However, in the prior art, when stamping automotive body sheet metal parts, due to the stamping process, some of the processed plates will get stuck on the processing table on the lower template. After processing, the workers often need to manually pull them upwards to remove the processed plates in order to continue working. This is inconvenient and also makes it easy to bend the processed plates. Therefore, we provide a stamping die for processing automotive body sheet metal parts to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a stamping die for processing automotive body sheet metal parts, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stamping table, wherein a lower die is fixedly installed in the middle of the stamping table, and a telescopic groove is provided around the inner side of the lower die, wherein a stripping template is elastically connected in the telescopic groove, and a top support plate is hinged to the middle of both sides of the stripping template through a hinge shaft.

[0007] Preferably, a hydraulic cylinder is provided on the top of the stamping table, and a telescopic rod is inserted into the bottom of the hydraulic cylinder. The bottom of the telescopic rod is fixedly connected to the upper mold.

[0008] Preferably, the upper die is parallel to the lower die located in the middle of the stamping table, and the stamping column at the bottom of the upper die is parallel to the stamping groove opened on the lower die.

[0009] Preferably, a spring is provided in the telescopic groove, the bottom of the spring is connected to the inner wall of the ejector plate, the top of the spring is connected to the ejector plate, and the top of the ejector plate is parallel to the inner surface of the lower mold.

[0010] Preferably, the top support plate, which is hinged to the side of the stripping template by a hinge shaft, extends out from the lower mold, and the stamping table has grooves on both sides of the lower mold that are parallel to the stripping template, with the bottom of the other end of the stripping template inserted into the groove.

[0011] Preferably, the slide groove has retaining grooves on both sides, and the part of the top support plate that is inserted into the slide groove has retaining blocks on both sides, the retaining blocks are inserted into the retaining grooves, and the bottom of the part of the top support plate that is inserted into the slide groove has rollers.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention discloses a stamping die for processing automotive body sheet metal parts. When stamping automotive body sheet metal parts, the parts are first placed in the lower die. Then, a hydraulic cylinder drives the bottom telescopic rod to extend and retract the upper die. The upper die, along with the stamping column at its bottom, begins to stamp the automotive body sheet metal parts. After stamping, the hydraulic cylinder drives the telescopic rod to raise the upper die. Then, it pushes the top support plate against the inside of the lower die. The top support plate then presses against the ejector plate through the hinge shaft at its top, causing the ejector plate to rise. As the ejector plate rises, it simultaneously raises the stamped automotive body sheet metal parts on the lower die, allowing the parts to separate from the lower die. This completes the rapid demolding of the automotive body sheet metal parts. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a stamping table 1, a lower mold 5 fixedly installed in the middle of the stamping table 1, a telescopic groove 6 opened around the inner perimeter of the lower mold 5, a stripping plate 8 elastically connected in the telescopic groove 6, and a top support plate 10 hinged to the middle of both sides of the stripping plate 8 via a hinge shaft 9; a hydraulic cylinder 2 is installed at the top of the stamping table 1, a telescopic rod 3 is inserted into the bottom of the hydraulic cylinder 2, and an upper mold 4 is fixedly connected to the bottom of the telescopic rod 3; the upper mold 4 is parallel to the lower mold 5 installed in the middle of the stamping table 1, and the stamping column installed at the bottom of the upper mold 4 is parallel to the stamping groove opened on the lower mold 5; a spring 7 is installed in the telescopic groove 6, and the bottom of the spring 7... The top of the spring 7 is connected to the inner wall of the ejector plate 8, and the top of the ejector plate 8 is parallel to the inner surface of the lower mold 5. The top support plate 10, which is hinged to the side of the ejector plate 8 by the hinge shaft 9, extends out of the lower mold 5. The stamping table 1 has a sliding groove 11 on both sides of the lower mold 5 parallel to the ejector plate 8. The bottom of the other end of the ejector plate 8 is inserted into the sliding groove 11. The sliding groove 11 has a retaining groove 12 on both sides. The part of the top support plate 10 inserted into the sliding groove 11 is provided with retaining blocks 14 on both sides. The retaining blocks 14 are inserted into the retaining groove 12. The bottom of the part of the top support plate 10 inserted into the sliding groove 11 is provided with a roller 13.

[0021] In practical use, when stamping automotive body sheet metal parts, the automotive body sheet metal parts are first placed in the lower mold 5. Then, the hydraulic cylinder 2 drives the bottom telescopic rod 3 to extend and retract the upper mold 4, causing the upper mold 4 to move and press the stamping column at its bottom to stamp the automotive body sheet metal parts. After stamping is completed, the hydraulic cylinder 2 drives the telescopic rod 3 to raise the upper mold 4, which then pushes the top support plate 10 through the inside of the lower mold 5. This causes the top support plate 10 to press against the release plate 8 through the hinge shaft 9 at the top of the top support plate 10, thus releasing the release plate. As the template 8 rises, the ejector template 8 simultaneously lifts the stamped car body sheet metal parts on the lower mold 5, causing the car body sheet metal parts to detach from the lower mold 5; this completes the rapid demolding of the car body sheet metal parts. The outer bottom of the slide 11 is held in the holding grooves 12 on both sides of the slide 11 by the holding block 14, preventing the outer bottom of the top support plate 10 from detaching from the slide 11. Rollers 13 are provided on the outer bottom of the top support plate 10, which enable the top support plate 10 to slide quickly in the slide 11 when pushed.

[0022] Although the illustrative specific embodiments of this application have been described above to enable those skilled in the art to understand this application, this application is not limited to the scope of the specific embodiments. For those skilled in the art, all applications utilizing the concept of this application are protected as long as various variations are within the spirit and scope of this application as defined and determined by the appended claims.
