Summary of the Utility Model

[0004] The problem solved by the utility model is that in the prior art, flattening and punching operations usually need to be carried out using different dies.

[0005] To solve the above problems, the utility model provides a stamping die for flattening and punching wind power pipe sleeves, which includes: a workpiece fixing part for fixing the workpiece to be processed; a flattening part arranged on one side of the workpiece fixing part, and the flattening part moves towards the workpiece fixing part to apply a force to the workpiece and flatten at least part of the workpiece; a punching unit including a punch needle arranged towards the workpiece fixing part, and the punching unit drives the punch needle to move towards the workpiece fixing part to punch the workpiece.

[0006] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The workpiece to be processed is arranged on the workpiece fixing part, and a force is applied to the workpiece through the flattening part, so as to flatten at least part of the workpiece. The punching unit drives the punch needle to move towards the workpiece fixing part to realize the punching operation of the workpiece. The combined use of the punching unit and the flattening part enables the flattening and punching operations to be continuously completed on one die, improving the production efficiency. The workpiece directly completes the flattening and punching operations on the workpiece fixing part, avoiding deformation or displacement of the workpiece during the transportation process from the flattening die to the punching die, thereby ensuring the accuracy of the punching position and improving the processing precision.

[0007] Furthermore, the stamping die includes: an upper die provided with a punching unit; a lower die with a workpiece fixing part arranged on the side close to the upper die; a guide rod, one end of which is slidably connected to the upper die and the other end is fixedly connected to the lower die; wherein, when the upper die moves along the axial direction of the guide rod, it drives the punching unit to move towards or away from the workpiece fixing part.

[0008] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: When the upper die moves along the axial direction of the guide rod, it drives the punching unit to move, thereby completing the punching of the workpiece and improving the processing efficiency.

[0009] Further, the flattening part includes: a pressure plate disposed between the upper die and the lower die, the pressure plate sleeved on the guide rod and slidably connected to the guide rod; a transmission shaft, one end of the transmission shaft passing through the upper die and fixedly connected to the pressure plate, and the transmission shaft driving the pressure plate to move in a direction close to or away from the workpiece fixing part.

[0010] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The transmission shaft drives the pressure plate to move, realizing precise control of the flattening operation and ensuring that the deformation amount and deformation position of the wind power pipe sleeve during the flattening process meet the design requirements.

[0011] Further, the stamping die includes: an elastic component, one end of the elastic component connected to the upper die and the other end connected to the pressure plate.

[0012] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By arranging an elastic component between the upper die and the pressure plate, when the pressure plate performs a flattening operation on the workpiece, the elastic component can absorb part of the impact energy, preventing noise, vibration and workpiece damage caused by the direct contact between the pressure plate and the workpiece. In addition, the elastic component can buffer the upper die when the upper die drives the punching unit to perform a punching operation, avoiding workpiece deformation or damage caused by excessive instantaneous impact force. Then, the elastic component can also reset the upper die after the upper die drives the punching unit to perform a punching operation, thereby improving the production efficiency.

[0017] Furthermore, the workpiece fixing part includes: a base, which is fixedly connected to the lower die; a stop part, which is arranged on the base; wherein, when the workpiece is arranged on the workpiece fixing part, at least part of the stop part abuts against one end of the workpiece in the axial direction, and the base abuts against the side surface of the workpiece in the radial direction.

[0018] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The base is fixedly connected to the lower die, providing a stable basic support for the workpiece. The stop part enables precise positioning of the workpiece in the axial direction. At least part of the stop part abuts against one end of the workpiece in the axial direction, ensuring that the workpiece will not shift or slide axially during the processing. When the workpiece is placed on the workpiece fixing part, the base closely abuts against the side surface of the workpiece in the radial direction, effectively preventing the movement of the workpiece during the processing. The combined design of the base and the stop part can adapt to workpieces of different sizes and shapes, enhancing the versatility of the stamping die and reducing the equipment investment cost.

[0019] Furthermore, the workpiece fixing part further includes: a bracket, which is arranged on the lower die; wherein, when the workpiece is arranged on the workpiece fixing part, the bracket abuts against the side surface of the workpiece in the radial direction.

[0020] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The setting of the bracket enables the workpiece to be supported in the radial direction. When the workpiece is placed on the base, the bracket abuts against the side surface of the workpiece in the radial direction, effectively preventing the shaking and movement of the workpiece during the processing, enhancing the stability of the workpiece during the processing, and ensuring the processing accuracy and efficiency.

[0021] Furthermore, a second through hole is provided at a position of the base corresponding to the punching unit; when the punching unit drives the punch to move in the direction close to the workpiece fixing part, at least part of the punch passes through the second through hole.
