Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die with protective function. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. They are called cold stamping dies. When stamping materials, continuous operation is usually required, which poses safety hazards.

[0003] Patent CN212190981U discloses a stamping die for metal sheet processing. Although the stamping die can prevent the finished product and waste from accumulating by dropping them onto the worktable and can prevent the waste and finished product from mixing by setting different collection boxes, the above patent still has some defects in actual use. When using the above patent to stamp the die, the die cannot be protected. As a result, when the sheet metal is placed in the die, the die moves downward to stamp the sheet metal, which can easily cause injury to the worker's hands.

[0004] Therefore, there is an urgent need to provide a stamping die with protective functions, which uses handles, pull rods and locking blocks to protect the hands. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned patent in that the mold cannot be protected during the stamping process, and the mold moves downward to stamp the sheet metal during the process of placing the sheet metal, which can easily cause injury to the workers' hands, this utility model provides a stamping mold with protective function. The stamping mold achieves the purpose of protecting the hands by setting handles, pull rods and locking blocks.

[0006] This utility model is achieved through the following technical means: a stamping die with protective function, including guide rods, a first die, a second die and a limiting frame. Four guide rods are connected to the first die, and the second die is slidably arranged on the four guide rods. The second die can be inserted into the first die. Multiple limiting frames are provided on the first die, and it also includes a handle, a pull rod and a locking block. A pull rod is slidably arranged on the limiting frame, a handle is connected to the pull rod, and a locking block is connected to the pull rod.

[0007] In a preferred embodiment of the present invention, the invention further includes a movable rod, a movable plate, a push plate, and a first elastic element. The push plate is slidably disposed on the first mold, the movable rod is connected to the push plate, the movable plate is connected to the movable rod, and the first elastic element is sleeved on the movable rod. The two ends of the first elastic element are respectively connected to the first mold and the movable plate.

[0008] In a preferred embodiment of the present invention, the invention further includes a fixing block, a limiting rod, a knocking block, and a second elastic element. Two fixing blocks are provided on the second mold. A limiting rod is slidably provided on the fixing block. A knocking block is connected to the limiting rod. A second elastic element is sleeved on the limiting rod. The two ends of the second elastic element are respectively connected to the fixing block and the knocking block.

[0009] In a preferred embodiment of the present invention, a protective pad is also included, with the same protective pad being uniformly connected on the first mold and the second mold.

[0010] In a preferred embodiment of the present invention, a third elastic element is further included. The third elastic element is sleeved on the pull rod, and both ends of the third elastic element are connected to the limiting frame and the pull rod, respectively.

[0011] In a preferred embodiment of the present invention, a collection frame is also included, and the first mold is provided with a collection frame.

[0012] Based on the above description of the structure of this utility model, the design starting point, concept, and advantages of this utility model are as follows:

[0013] 1. By operating the second mold to move downward and contact the clamping block, the clamping block supports the second mold, thereby preventing injury to the worker's hands during the stamping process.

[0014] 2. The second mold moves upward and contacts the moving plate, pressing it upward. The moving plate drives the moving rod to move upward, and the first elastic element deforms accordingly. The moving rod drives the push plate to move upward, and the push plate drives the sheet metal to move upward, thereby making the sheet metal detach from the first mold, thus facilitating material removal.

[0015] 3. The second mold drives the fixed block to move downward, the fixed block drives the limit rod to move downward, the limit rod drives the hammer block to move downward, so that the hammer block contacts the sheet metal and squeezes it, thereby achieving the purpose of quickly removing the edges and corners of the sheet metal.

[0021] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0022] Example 1

[0023] A stamping die with protective function, see Figures 1-2 As shown, the device includes guide rods 1, a first mold 2, a second mold 3, a limiting frame 4, protective pads 16, a third elastic element 17, and a collection frame 18. Four guide rods 1 are welded onto the first mold 2 in a rectangular arrangement. The second mold 3 is slidably mounted on the four guide rods 1, allowing it to engage with the first mold 2. Limiting frames 4 are symmetrically mounted on the upper part of the first mold 2 via bolts. Identical protective pads 16 are evenly connected to both the first mold 2 and the second mold 3 for protective purposes. To prevent damage caused by contact and friction between the first mold 2 and the second mold 3, a third elastic element 17 is sleeved on the pull rod 6. The two ends of the third elastic element 17 are connected to the limit frame 4 and the pull rod 6 respectively. The third elastic element 17 is used to reset the pull rod 6. A collection frame 18 is provided on the first mold 2 by bolts. The collection frame 18 is used to collect the stamped sheet metal. It also includes a handle 5, a pull rod 6 and a locking block 7. The pull rod 6 is slidably provided on the limit frame 4. The handle 5 is provided on the pull rod 6 by welding. The locking block 7 is provided on the pull rod 6 by welding.

[0024] When the operator needs to use this device to stamp sheet metal, the operator will not install it in the appropriate position. Instead, the operator will place the sheet metal to be stamped on the first mold 2. After placement, the operator will operate the second mold 3 to move downwards and contact the locking block 7, thereby allowing the locking block 7 to support the second mold 3 and prevent injury to the operator's hands during the stamping process. After the operator places the second mold 3 in the appropriate position, the operator will grasp and pull the handle 5 outwards. The handle 5 will drive the pull rod 6 to move outwards, and the third elastic element 17 will deform accordingly. The locking block 7 of the pull rod 6 will move outwards, so that the locking block 7 is no longer in contact with the second mold 3. This will allow the second mold 3 to continue to move downwards and contact the sheet metal for stamping. After stamping is completed, the operator will operate the second mold 3 to move upwards to reset, so that the second mold 3 is no longer in contact with the sheet metal. At the same time, the operator will release the handle 5. The third elastic element 17 will drive the pull rod 6 to move in the opposite direction to reset, the pull rod 6 will drive the locking block 7 to move in the opposite direction to reset, and the locking block 7 will drive the handle 5 to move in the opposite direction to reset. Then the operator will remove the stamped sheet metal.

[0025] Example 2

[0026] Based on Example 1, see [link to Example 1] Figure 3 As shown, it also includes a movable rod 8, a movable plate 9, a push plate 10 and a first elastic element 11. The push plate 10 is slidably arranged in the middle position inside the first mold 2. The movable rod 8 is provided at the bottom of the push plate 10 by welding. The movable plate 9 is provided at the lower part of the movable rod 8 by welding. The first elastic element 11 is sleeved on the movable rod 8. The two ends of the first elastic element 11 are connected to the first mold 2 and the movable plate 9 respectively.

[0027] See Figure 3 and Figure 4 As shown, it also includes a fixing block 12, a limiting rod 13, a knocking block 14, and a second elastic element 15. The fixing block 12 is symmetrically installed on the upper rear part of the second mold 3 by bolts. The limiting rod 13 is slidably installed on the fixing block 12. The knocking block 14 is installed at the bottom of the limiting rod 13 by welding. The second elastic element 15 is sleeved on the limiting rod 13. The two ends of the second elastic element 15 are connected to the fixing block 12 and the knocking block 14 respectively.

[0028] After the second mold 3 finishes stamping the sheet metal, the operator moves the second mold 3 upward to contact the moving plate 9 and press it upward. The moving plate 9 drives the moving rod 8 upward, and the first elastic element 11 deforms accordingly. The moving rod 8 drives the push plate 10 upward, and the push plate 10 drives the sheet metal upward, thereby making the sheet metal detach from the first mold 2, thus facilitating material removal. After removal, the operator pushes the sheet metal backward, causing the stamped sheet metal to move backward. At the same time, the operator operates the second mold 3 downward again to continue stamping the sheet metal. The second mold 3 drives the fixing block 12 downward, the fixing block 12 drives the limiting rod 13 downward, and the limiting rod 13 drives the knocking block 14 downward, thus making the knocking block 14 contact the sheet metal and press it, thereby quickly removing the edges of the sheet metal. The sheet metal with the edges removed falls into the collection frame 18, which collects the sheet metal for easy removal later. At the same time, the edges move forward and are discharged. After the sheet metal stamping is completed, the operator operates the second mold 3 upward to reset it.
