Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in 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] Reference Figures 1-3 An embodiment provided by the utility model: a steel roll stamping processing die quick replacement mechanism, including two connecting covers 3, the inner wall of opposite side of two connecting covers 3 is rotatably connected with first tension spring 4, the adjacent end of two first tension springs 4 is rotatably connected with control block 5, two control blocks 5 are rotatably connected between two connecting covers 3, the surface of adjacent side of two connecting covers 3 is provided with triangular groove 6, the inside of two triangular grooves 6 is provided with triangular block 7, two triangular blocks 7 are fixedly connected between two connecting covers 3, the rear side of upper connecting cover 3 is fixedly connected with clamping plate 2, the front side of lower connecting cover 3 is fixedly connected with punch 1, the bottom of punch 1 is provided with lower die holder 22, the left side of lower die holder 22 is provided with self-adapting material guiding assembly, and the self-adapting material guiding assembly is used for adapting different models of steel rolls.

[0025] Specifically, the left control block 5 is forced to rotate by applying an external force to the left control block 5, and the rotation of the left control block 5 drives the right control block 5 to rotate synchronously. In the process of rotating the control block 5, the first tension spring 4 connected to the control block 5 is pulled to cause elastic deformation of the first tension spring 4 and store elastic potential energy. When the control block 5 rotates to a parallel state with the connecting cover 3, the limiting effect of the connecting cover 3 on the control block 5 disappears, and at this time the two connecting covers 3 can be separated. With the separation of the connecting cover 3, the triangular block 7 on the connecting cover 3 is separated from the triangular groove 6 opened on the other connecting cover 3. Since the limiting effect of the triangular groove 6 on the triangular block 7 disappears, the connection constraint between the punch 1 and the connecting cover 3 is released, so that the punch 1 can be quickly removed. Finally, the force of the tank control block 5 resets the control block 5 to prepare for installing the punch 1. When the punch 1 needs to be installed, it only needs to be aligned with the connecting cover 3 to quickly replace the punch 1, solving the problem of delaying the production plan due to replacing the punch 1.

[0026] With reference to Figure 1 , Figure 4 and Figure 5 , the self-adapting material guiding assembly comprises a connecting block 8 fixedly connected between the lower die frame 22 and the top of the connecting block 8 is provided with two clamping blocks 10, the adjacent side of each of the two clamping blocks 10 is rotatably connected with a first rotating disc 13, the adjacent side of each of the two first rotating discs 13 is rotatably connected with two second rotating discs 14, the adjacent side of each of the four second rotating discs 14 is rotatably connected with a third rotating disc 15, and the second tension spring 11 is fixedly connected between the two clamping blocks 10.

[0027] Specifically, the two clamping blocks 10 are pulled apart, and in the process of pulling apart the clamping blocks 10, the clamping blocks 10 pull the second tension spring 11 connected between them, so that the second tension spring 11 is stretched and stores elastic potential energy. Then the steel coil is placed between the two clamping blocks 10, and then the clamping blocks 10 are loosened. At this time, the second tension spring 11 will restore to its original state due to elastic deformation, pull the two clamping blocks 10 towards each other, reset the clamping blocks 10 and clamp the steel coil. When the third rotating disc 15 contacts the steel coil, the steel coil will generate a reaction force on the third rotating disc 15. Under the action of the reaction force, the third rotating disc 15 will rotate slightly to find the most suitable position to adapt to the steel coil. Since the first rotating disc 13, the second rotating disc 14 and the third rotating disc 15 are rotatably connected, they can be adjusted cooperatively, so that the whole self-adapting material guiding assembly can adapt to different types of steel coils, thereby solving the problem of material feeding deviation.

[0032] With reference to Figure 1 and Figure 4 , the inner part of each of the two clamping blocks 10 is slidably connected with two control rods 9, and the top of each of the two clamping blocks 10 is fixedly connected with a limiting plate 12.

[0033] Specifically, the control rod 9 is used for controlling the left horizontal sliding of the clamping block 10, and the limiting plate 12 is used for limiting the coiled steel.

[0037] Specifically, the outer guide column 20 is used for accurate positioning.

[0038] With reference to Figure 1 , the top of the lower die holder 22 is fixedly connected with a lower die plate 21, and the lower die plate 21 is located at the bottom of the punch 1.

[0039] Specifically, the lower die holder 22 is used for fixing the lower die plate 21, and the lower die plate 21 is located directly below the punch 1 to ensure the stamping precision.

[0040] Working principle: when the punch 1 needs to be replaced, an external force is applied to the left control block 5 to make it rotate, and since the two control blocks 5 rotate synchronously, the right control block 5 also rotates, in the process of rotating the control block 5, the first tension spring 4 is pulled and elastically deformed to store elastic potential energy, when the control block 5 rotates to be parallel to the connecting cover 3, the limiting of the connecting cover 3 to the control block 5 disappears, at this time, the two connecting covers 3 can be separated, with the separation of the connecting cover 3, the triangular block 7 is separated from the triangular groove 6, the connection constraint between the punch 1 and the connecting cover 3 is removed, so that the punch 1 can be quickly removed, then the external force on the control block 5 is removed, the first tension spring 4 resets the control block 5, preparing for the next installation of the punch 1, when installing the punch 1, only the connecting cover 3 needs to be aligned by sliding to complete the quick installation, so as to achieve the purpose of quickly replacing the punch 1, effectively avoiding the delay of production plan due to replacing the punch 1;

[0041] Before feeding, first pull open the two clamping blocks 10, in this process, the second tension spring 11 is stretched and stores elastic potential energy, then put the coil steel between the two clamping blocks 10, after loosening the clamping blocks 10, the second tension spring 11 restores to its original shape due to elastic deformation, pulling the two clamping blocks 10 to move towards each other, thereby clamping the coil steel, when the third turntable 15 contacts the coil steel, the coil steel generates a reaction force on it, making the third turntable 15 rotate slightly to find the most suitable position to adapt to the coil steel, and because the first turntable 13, the second turntable 14 and the third turntable 15 are rotationally connected, they can adjust cooperatively, so that the whole self-adaptive material guiding assembly can adapt to different types of coil steels, solving the problem of feeding deviation;

[0042] When the stamping operation is performed, the upper die holder 18 moves downward under the action of the press, driving the clamping plate 2 and the punch 1 to move downward, the inner guide column 16 moves downward with the clamping plate 2, playing a guiding role to ensure the accuracy of the stamping process, the ejection plate 19 plays a role in ejecting the workpiece from the punch 1 after the stamping is completed, the lower die holder 22 is fixed with the lower die plate 21, the coil steel is accurately fed to the lower die plate 21 through the self-adaptive material guiding assembly, the punch 1 moves downward to stamp the coil steel, completing the stamping work of the coil steel.
