Technical Field

[0001] The utility model relates to the field of die core replacement, in particular to an improved structure for rapid die change of a stamping progressive die. Background Technique

[0002] A stamping die is a tool used to produce parts during the stamping process, mainly used to process metal sheets into required shapes and sizes. It is one of the essential and important equipment in stamping processing. There are various types of stamping dies, and different types have different uses. Stamping dies play a crucial role in modern industrial production. Their functions not only lie in producing parts, but also in effectively reducing costs and improving production efficiency. Using high-precision stamping dies can not only ensure the accuracy and stability of production, but also greatly improve production efficiency, speed up the production rhythm, and meet the market demand. The die core is the central part of the product in the die. What shape and specification of the product is stamped depends on what kind of die core is installed.

[0003] Due to the miscellaneous part numbers of auto parts, small order quantities, frequent switching of stamping machine types, and many products being similar, the original die parts products cannot be utilized after the machine type is switched. At the same time, the manufacturing cost of the die is relatively high, so the cost is relatively large when stamping different parts and products, and it is not competitive in the industry.

[0004] Therefore, it is necessary to invent an improved structure for rapid die change of a stamping progressive die to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an improved structure for rapid die change of a stamping progressive die to solve the problems mentioned in the above background technique, that is, due to the miscellaneous part numbers of auto parts, small order quantities, frequent switching of stamping machine types, many products being similar, the original die parts products cannot be utilized after the machine type is switched, and at the same time, the manufacturing cost of the die is relatively high, so the cost is relatively large when stamping different parts and products, and it is not competitive in the industry.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An improved structure for rapid die change of a stamping progressive die includes an upper die, the upper die and the lower die are symmetrically distributed up and down, and installation grooves are opened inside both the upper die and the lower die. Die cores are fitted and installed inside both installation grooves. Activity cavities are opened inside both the upper die and the lower die, and the activity cavities are communicated with the channel grooves. A rotating rod is rotatably connected inside the activity cavity, and a first thread is arranged on the outer circle of the rotating rod. A moving block is threadedly connected to the outer circle of the first thread. A vertical rod is threadedly connected inside the moving block, and the vertical rod is rotatably connected to a clamping plate through a connecting short rod. The clamping plate is used for clamping the die core.

[0007] Preferably, the same end of the two rotating rods extends to the area outside the upper mold and the lower mold, and the rotating rod is rotatably connected to the internal through-openings of the upper mold and the lower mold through bearings, and a turntable is fixedly connected to the end of the rod body of the rotating rod located outside the upper mold and the lower mold, which facilitates the rotation of the rotating rod and the movement of the clamping plate, thereby facilitating the clamping and separation and replacement of the mold core.

[0008] Preferably, the number of threads 1 on the outer ring of a rotating rod is two, and the two threads 1 are symmetrically distributed, and the thread directions of the two threads 1 are different, so that when the rotating rod rotates and the two moving blocks are threadedly connected to the threads 1 in different directions, the two moving blocks can move towards each other or move apart.

[0009] Preferably, two moving blocks are arranged inside one active cavity, and the side walls of the moving blocks are in contact with and slidably connected to the inner walls of the active cavity, thereby ensuring stable movement of the moving blocks.

[0010] Preferably, the vertical rod slides inside the groove, and a second thread is provided at one end of the vertical rod away from the clamping plate, and the second thread is threadedly connected to a thread groove provided at one end of the moving block close to the groove, so as to facilitate subsequent replacement of the clamping plate.

[0011] Preferably, the connecting short rod is composed of a circular disc and a short rod with a diameter smaller than the circular disc and fixedly connected to the circular disc, and the end of the short rod is also fixedly connected to the clamping plate, and the circular disc and the short rod rotate inside a rotating groove provided inside the vertical pole, and the inner wall of the rotating groove fits with the outer wall of the circular disc and the short rod. In this way, after the vertical pole is twisted to achieve threaded connection with the threaded groove, the angle of the clamping plate can be adjusted, which is convenient for clamping the mold core when the clamping plate is subsequently moved to fit the two side ends of the mold core.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] 1. The utility model twists the turntable fixedly connected to the end of the rotating rod so that the two movable blocks threadedly connected with the two threads at the outer ring of the rotating rod can move in directions toward or away from each other under the limiting action of the movable cavity, which is convenient for clamping the two side ends of the mold core installed in the installation groove, and convenient for the subsequent installation and replacement of the mold core. At the same time, the vertical rod rotatably connected to the clamping plate is threadedly connected to the movable block, so that the clamping plate can be removed by twisting the vertical rod to replace different types of clamping plates and then install and clamp different types of mold cores, which is convenient for the subsequent use of the entire mold. In this way, the same machine model can perform stamping processing on products of different shapes and specifications;

[0014] 2. Meanwhile, the clamping plate and the vertical rod are rotatably connected through a connecting short rod. In this way, after the vertical rod is twisted and threadedly connected to the thread groove, the angle of the clamping plate is adjustable. At the same time, when the clamping plate moves and fits the two end parts of the die core, the self-limitation of the clamping plate can be realized. At this time, the clamping plate will not rotate, which is convenient for the subsequent clamping of the die core end by the clamping plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will further introduce the present invention in detail with reference to the drawings.

[0023] The present invention provides as Figures 1-4An improved structure for rapid die change of a stamping progressive die shown, including an upper die 1, the upper die 1 and the lower die 2 are symmetrically distributed up and down, and installation grooves 3 are opened inside both the upper die 1 and the lower die 2, and die cores 4 are fitted and installed inside the two installation grooves 3. Activity cavities 5 are opened inside both the upper die 1 and the lower die 2, and the activity cavities 5 are communicated with the channel 6. A rotating rod 8 is rotatably connected inside the activity cavity 5, and a first thread 9 is arranged on the outer ring of the rotating rod 8, and a moving block 7 is threadedly connected to the outer ring of the first thread 9. A vertical rod 10 is threadedly connected inside the moving block 7, and the vertical rod 10 is rotatably connected to a clamping plate 13 through a connecting short rod 14, and the clamping plate 13 is used for clamping the die core 4.

[0024] The same end parts of the two rotating rods 8 extend to areas outside the upper die 1 and the lower die 2, and the rotating rods 8 are rotatably connected to the through holes inside the upper die 1 and the lower die 2 through bearings, and a turntable is fixedly connected to the rod end parts of the rotating rods 8 located in the areas outside the upper die 1 and the lower die 2, which is convenient for rotating the rotating rods 8, and further realizes the movement of the clamping plate 13, and is convenient for clamping and separating and replacing the die core 4.

[0025] The number of the first threads 9 on the outer ring of one rotating rod 8 is set to two, and the two first threads 9 are symmetrically distributed, and the thread directions of the two first threads 9 are different. In this way, during the rotation of the rotating rod 8, when the two moving blocks 7 are threadedly connected to the first threads 9 in different directions, the two moving blocks 7 can move towards each other or move away from each other.

[0026] Two moving blocks 7 are arranged inside one activity cavity 5, and the side walls of the moving blocks 7 are attached to and slidably connected to the inner walls of the activity cavity 5 to ensure the stable movement of the moving blocks 7.

[0027] The vertical rod 10 slides inside the channel 6, and a second thread 11 is arranged at the end part of the vertical rod 10 away from the clamping plate 13, and the second thread 11 is threadedly connected to a thread groove 12 arranged at the end part of the moving block 7 close to the channel 6, which is convenient for the subsequent replacement of the clamping plate 13.

[0028] The connecting short rod 14 is composed of a disc and a short rod with a diameter smaller than the disc and fixedly connected to the disc, and the end part of the short rod is also fixedly connected to the clamping plate 13, and the disc and the short rod rotate inside a rotating groove 15 arranged inside the vertical rod 10, and the inner wall of the rotating groove 15 is attached to the outer walls of the disc and the short rod. In this way, after the vertical rod 10 is twisted and threadedly connected to the thread groove 12, the angle of the clamping plate 13 is adjustable, which is convenient for clamping the die core 4 when the clamping plate 13 moves and fits the two end parts of the die core 4 subsequently.

[0029] Working principle: When using a stamping progressive die with an improved structure for quick die change, first, the turntable fixedly connected to the end of the rotating rod 8 is twisted to make the two moving blocks 7 threadedly connected to the two differently oriented threads 9 on the outer ring of the rotating rod 8 move in opposite or away directions under the limiting action of the inner wall of the movable cavity 5, facilitating the clamping of both end parts of the die core 4 installed inside the installation groove 3, thus facilitating the subsequent installation and replacement of the die core 4. At the same time, the two clamping plates 13 move synchronously towards each other, making the final die core 4 in the middle position during the clamping process of the die core 4. In this way, the installation positions of the die core 4 in the upper die 1 and the lower die 2 are the same, facilitating the subsequent use of the die and eliminating the need for manual alignment and installation of the die core 4, with convenient operation;

[0030] Meanwhile, the vertical rod 10 rotatably connected to the clamping plate 13 is threadedly connected to the moving block 7. Thus, by twisting the vertical rod 10, the clamping plate 13 can be removed and different types of clamping plates 13 can be replaced to install and clamp different types of die cores 4 (the vertical rod 10 can be twisted by passing the thumb and index finger through the channel 6 on both sides of the clamping plate 13). The clamping plate 13 and the vertical rod 10 are rotatably connected through a connecting short rod 14. In this way, after the vertical rod 10 is twisted and threadedly connected to the threaded groove 12, the angle of the clamping plate 13 is adjustable, facilitating the clamping of the die core 4 when the clamping plate 13 moves to fit the two end parts of the die core 4 subsequently. When the clamping plate 13 fits the end wall of the die core 4, self-limitation of the clamping plate 13 can be achieved. At this time, the clamping plate 13 will not rotate, facilitating the subsequent firm clamping of the end part of the die core 4 by the clamping plate 13.

[0031] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
