[0026] As a further implementation scheme of this scheme, the punching knife 321 and the pre-punching block 322 are arranged directly above the range of the punching groove 42, and the punching knife 321 and the limiting arc plate 41 are spatially displaced, which facilitates the punching knife 321 and the pre-punching block 322 to punch and cut the water pump guide vane raw material into primary water pump guide vanes.
[0027] As a further implementation scheme of the present scheme, a limiting arc plate 41 is arranged between the punching knife 321 and the secondary stamping block 63, and the arc center of the limiting arc plate 41 and the arc surface axis center of the stamping groove 42 are on the same axial line. The limiting arc plate 41 can prevent the water pump guide vane from warping due to the punching force when the punching knife 321 cuts the water pump guide vane raw material.
[0028] As a further implementation scheme of the present scheme, the pre-punching block 322 has the same shape as the secondary punching block 63. The pre-punching block 322 and the secondary punching block 63 are located on the same vertical plane and can be spatially offset and parallel. Before punching the water pump blades, the pre-punching block 322 can pre-punch the water pump raw material to be punched into the required shape, and after the water pump blades are punched, the secondary punching block 63 can punch and shape the punched water pump blades.
[0029] As a further implementation scheme of the present invention, there are two limit rods 61, which are symmetrically arranged on the outside of the sliding column 6. The two ends of the limit rod 61 are respectively fixedly connected to the circular plate 62 and the secondary stamping block 63, which can ensure that the secondary stamping block 63 fixedly connected to the sliding column 6 always keeps moving in the vertical direction.

[0031] As a further implementation scheme of the present invention, the punching knife 321, the pre-punching block 322 and the secondary punching block 63 can be engaged in the punching groove 42. The curvature of the blade of the punching knife 321 is the same as the curvature of the arc surface of the punching groove 42, which can ensure that the water pump guide vane punched and cut by the punching device has a better forming effect.
[0032] Working process: During use, the equipment is powered by an external power supply. When the water pump guide vane punching device is used to punch and cut the water pump guide vane raw material, the water pump guide vane raw material is continuously conveyed from the conveying device 5 fixedly connected to the device box 1 to the bearing plate 4, and then the punching machine 3 fixedly connected to the inner side of the device box 1 is started, and the telescopic rod 31 in the punching machine 3 is controlled to move vertically downward, so that the pressing plate 32 fixedly connected to the outer side of the telescopic rod 31 moves toward the bearing plate 4, and at the same time, the punching knife 321 fixedly connected to the pressing plate 32 and the pre-punching block 322 gradually move toward the bearing plate 4. The punching groove 42 opened on the inner side of the table 4 is approached until the pre-punching block 322 enters the punching groove 42, and the pre-punching block 322 can punch the raw material of the water pump guide vane into the shape of the arc set by the punching groove 42, and then under the continuous conveying thrust of the conveying device 5 on the water pump guide vane, the water pump guide vane punched into a fixed shape can be continuously conveyed to the bottom of the punching knife 321, so that under the pressure of the telescopic rod 31 on the pressing plate 32, the punching knife 321 on the pressing plate 32 can punch and cut the part of the raw material of the water pump guide vane punched by the pre-punching block 322, and under the punching knife During the punching process of 321, part of the raw material of the water pump guide vane is directly below the limiting arc plate 41 fixedly connected to the base plate 4, so that the primary water pump guide vane punched by the punching knife 321 is not easy to produce a large warping edge, and the deformation of the primary water pump guide vane after punching is small. After the primary water pump guide vane is punched into an independent individual, the primary water pump guide vane is still under the continuous conveying of the water pump guide vane raw material by the conveying device 5, and the primary water pump guide vane is pushed to the bottom of the secondary punching block 63. At this time, in the process of the telescopic rod 31 pushing the cutting plate 32 close to the base plate 4, the cutting plate 32 is fixed. The connected fixed block 323 gradually approaches the base plate 4, and at the same time, the circular plate 62 tightly attached to the outer side of the fixed block 323 moves tightly against the fixed block 323 until the secondary stamping block 63 suspended above the stamping groove 42 contacts the inner side of the stamping groove 42, and then with the movement of the cutting plate 32, the sliding column 6 of the fixed block 323 and the outer side of the limiting rod 61 slide. After the fixed block 323 and the secondary stamping block 63 are tightly attached together, the secondary stamping block 63 can perform secondary stamping on the primary water pump guide vane in the stamping groove 42, so that the primary water pump guide vane has a good molding effect and practical use effect.
