[0023] In order to make the technical scheme of the utility model more clear, the following will be combined with the drawings of the specific embodiments of the utility model to make a clear and complete description of the technical scheme of the embodiments of the utility model. The same reference signs in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] With reference to Figs. 1-3 The utility model discloses a hardware stamping die with protection function, including the stamping box 1, the middle part of stamping box 1 is equipped with stamping chamber 2, the inside of stamping chamber 2 is equipped with the stamping head 3 through the hydraulic mechanism, the stamping head 3 is equipped with the driving mechanism 4 on both sides of stamping chamber 2 and the stamping box 1, the driving mechanism 4 is equipped with the baffle 5, the downside of stamping head 3 is equipped with the stamping workbench 6, the upper surface of stamping workbench 6 is equipped with the stamping template 7.

[0025] With reference to Figs. 1-3 The driving mechanism 4 includes two first fixed plates 41 fixed on the same side of the stamping head 3 and two second fixed plates 42 fixed on the same side of the stamping box 1, the opposite side of the two first fixed plates 41 is rotatably installed with the movable plate 43, the opposite side of the two second fixed plates 42 is rotatably installed with the push plate 44, the other end of the movable plate 43 is movably connected with the push plate 44, when the stamping head 3 is driven by the hydraulic mechanism to carry out the stamping operation, the first fixed plate 41 fixed on both sides of the stamping head 3 goes down, drives the movable plate 43 to rotate around the rotation point of the first fixed plate 41, since the other end of the movable plate 43 is movably connected with the push plate 44, the movable plate 43 will push the push plate 44 to rotate around the rotation point of the second fixed plate 42 during the rotation, so that when the stamping head 3 goes down, the push plate 44 is synchronously unfolded to the outside under the pushing of the movable plate 43, so that the protection action is synchronized with the stamping stroke, ensures that before the stamping head 3 contacts the workpiece, the baffle 5 has been completely unfolded and pushes the limbs of the staff outward, completely isolates the possibility of personnel limbs from entering the dangerous area.

[0026] With reference to Figs. 1-3The baffle 5 is installed between the two push plates 44. The baffle 5 is transparent and made of polycarbonate or tempered glass. The baffle 5 is fixed between the two push plates 44 and unfolds synchronously with the push plates 44 during the stamping process to form a closed observation window. The transparent design allows the operator to observe the alignment of the stamping head 3 and the stamping template 7 and the workpiece forming process in real time, while effectively blocking metal debris from flying. The edges of the baffle 5 are treated with rubber edging and are connected to the push plates 44 by a snap-on quick-release structure. The snap-on quick-release structure is existing technology and will not be described in detail here. It facilitates quick replacement after damage.

[0027] Reference Figs. 1-3 The maximum diameter of the push plate 44 rotating around the second fixed plate 42 is less than the distance between the push plate 44 and the stamping worktable 6. When the push plate 44 rotates around the second fixed plate 42, the rotation trajectory of the push plate 44 is arc-shaped. The maximum diameter of this rotation trajectory is less than the vertical distance between the push plate 44 and the stamping worktable 6. This ensures that the push plate 44 avoids contact with the stamping worktable 6 during the unfolding process, avoids mechanical interference, and ensures that the effective protective height of the baffle 5 always covers the range of motion of the operator's hands. The uppermost end of the baffle 5 is located below the junction of the movable plate 43 and the push plate 44, and the lowermost end of the baffle 5 is aligned with the lowermost end of the push plate 44. The uppermost end of the baffle 5 is located below the connection point between the movable plate 43 and the push plate 44, which can prevent the baffle 5 from rubbing against the movable plate 43 during the unfolding or retraction process. The design that the lowermost end of the baffle 5 is flush with the bottom edge of the push plate 44 allows the baffle 5 to form the largest protective blocking area when fully unfolded.

[0028] The specific implementation method is as follows: During use, after the worker places the workpiece into the stamping template 7 during the stamping process, the hydraulic mechanism drives the stamping head 3 to press down. During the pressing process of the stamping head 3, the first fixed plate 41 descends synchronously with the stamping head 3. Then, the movable plate 43 is movably connected with the push plate 44. During the pressing process, the movable plate 43 will rotate around the rotation point of the first fixed plate 41 as the center, thereby pushing the push plate 44 outward. At this time, the push plate 44 can rotate around the rotation point of the second fixed plate 42 as the center. Then, the baffle 5 can push the worker's limbs out of the stamping area and form a transparent barrier area, so that the worker's limbs can no longer stay in the stamping area, avoiding injury during the stamping process. At the same time, the transparent barrier area formed by the baffle 5 can also prevent the workpiece or waste from splashing during the stamping process, greatly improving the overall safety.
