Description

Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to a stamping forming die. Background Art

[0002] Stamping is a forming process that uses a press and die to apply external forces to sheet metal, strip, tube, or profiles, causing them to plastically deform or separate, thereby obtaining the desired shape and size. Stamping materials are primarily hot-rolled and cold-rolled steel sheets and strips. Stamping dies are specialized equipment used in cold stamping to form parts. Currently, some materials require perforation.

[0003] At present, when the existing stamping die performs stamping processing on different workpieces, the corresponding stamping head needs to be replaced to complete the corresponding work. However, when the existing stamping die replaces the stamping head, there are complicated steps, which makes it very time-consuming, making the replacement operation time-consuming and labor-intensive, and thus reducing the overall work efficiency. Therefore, corresponding improvements need to be made based on the above problems. Utility Model Content

[0008] Preferably, the outer diameter of the magnet rod is adapted to the inner diameter of the fixing hole, and the bottom ends of the magnet rods extend into the interior of the fixing hole and are engaged therewith in a position-limiting manner.

[0009] Preferably, the six groups of limit plates are arranged in pairs, and the six groups of limit plates are arranged in a central symmetrical manner with the center point of the mounting plate as the center point.

[0010] Preferably, the width of the limiting plate is adapted to the distance between the inner walls on both sides of the limiting groove, and the limiting plate and the limiting groove are arranged in a limiting snap-fit arrangement.

[0011] Preferably, the three groups of fixing plates are centrally symmetrically arranged with the center point of the fixing disk as the center point.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By setting up components such as mounting plate, mounting slot, limit plate, mounting block, electric push rod, connecting plate, magnet rod, mounting ring, mounting column, fixing plate, punching head, fixing plate, limit slot and fixing hole, the problem of complicated steps when replacing the punching head of the existing stamping die can be effectively solved, which makes the replacement operation time-consuming and labor-intensive, thereby reducing the overall work efficiency.

[0014] Under the operation of the three groups of electric push rods, the corresponding connecting disks can be moved upward, so that the corresponding magnet rods can be moved upward in the corresponding fixing holes respectively, so that the bottom ends of the corresponding magnet rods can be separated from the inner walls of the bottom ends of the corresponding fixing holes. Due to the setting of the mounting ring, it is always possible to ensure that the three groups of connecting disks and the three groups of magnet rods can move upward synchronously. When the three groups of magnet rods are moved upward from the inside of the corresponding fixing holes, the user can move the punching head downward, so that the fixing disk and the mounting column can be moved downward accordingly, so that the three groups of fixing plates can be moved downward accordingly, so that the three groups of fixing plates can be separated from the corresponding two groups of limit plates respectively. When the mounting column is moved out of the inside of the mounting groove, the disassembly between the punching head and the mounting disk can be completed. Then, according to the above operation, the reverse operation can be performed, and the new punching head can be installed on the mounting disk. At this time, the punching head can be used normally by the electric hydraulic rod, so that the mold can be stamped. BRIEF DESCRIPTION OF THE DRAWINGS
