[0031] Example 1

[0032] The waste cutting device for the cast aluminum rotor is provided with a positioning structure, which can accurately position the product 2. Specifically:

[0033] The upper template 21 is fixedly connected to the upper plate of the vertical press by screws. It also includes a lower template 13, which is fixedly connected to the lower plate of the vertical press by screws. The upper template 21 is slidably connected to a third guide post 22. A guide sleeve 5 is slidably installed on the outer surface of the third guide post 22. The lower end of the third guide post 22 is connected to the lower template 13 through a stop block 12. The lower template 13 is connected with a positioning structure, which can quickly position and place the product 2 through the cooperation of a bottom support 10 and a positioning part 9. The positioning structure includes a bottom support 10 installed on the upper surface of the lower template 13. The product 2 is provided with an opening, which corresponds to the core shaft 1. The core shaft 1 is placed on the upper surface of the bottom support 10. A balance column is correspondingly arranged above the product 2, and the balance column is connected to the positioning part 9;

[0034] When in use, the waste cutting device for the cast aluminum rotor is a whole and is used to be installed on a vertical press with an up-and-down stroke. The upper template 21 and the lower template 13 are respectively installed on the upper and lower plates of the press through their waist-shaped slots using pressing plate screws. The upper template 21 and the lower template 13 are slidably connected by the third guide post 22 and the guide sleeve 5 for positioning the up-and-down structure. The third guide post 22 is installed on the upper surface of the lower template 13 through a stop block 12. The operator manually places the product 2 with the opening facing down on the bottom support 10. The inner diameter of the product 2 is matched with the core shaft 1 for placement. The balance columns on the product 2 and the 6 positions of the positioning part 9 are randomly matched for placement. Since the balance column is a drawing structure, a corresponding structure is opened on the positioning part 9 for matching and positioning. The balance column is made of aluminum. In order to prevent the balance column from being damaged during the positioning process, the positioning part 9 is made of pure copper with a lower hardness.

[0035] Embodiment 2

[0036] The waste cutting device for the cast aluminum rotor is also provided with a pressing structure. The small spring 4 and the large spring 7 cause the second guide post 27 and the first guide post 26 to move to press the product 2. Specifically:

[0037] The upper template 21 is connected with a clamping structure, which can clamp the product 2 by the cooperation of the small spring 4 and the large spring 7. The clamping structure includes a cutter head 14, which is mounted on the lower surface of the positioning plate 20 through a connecting piece 17. The positioning plate 20 is mounted on the lower surface of the connecting plate 19, and the connecting plate 19 is mounted on the lower surface of the mounting plate 18. Four guide pillars 26 are mounted on the lower surface of the mounting plate 18, and the guide pillars 26 slide through the upper surface of the connecting plate 19. The lower end of the guide pillar 26 passes through the lower surface of the connecting plate 19. A discharge plate 15 is connected through the bearing-large 25, and a guide column 27 is connected through the upper surface of the discharge plate 15 through the bearing-small 24, and the upper end of the guide column 27 slides through the lower surface of the connecting plate 19 and is fixedly connected to the mounting plate 18. A large spring 7 is installed in a surrounding manner on the outer surface of the guide column 16, and a small spring 4 is installed in a surrounding manner on the outer surface of the guide column 27. Washers 13 and 28 are respectively provided at the bottom of the large spring 7 and the small spring 4. A core rod-V 6 is installed in the middle of the cutter head 14, and the front end of the core rod-V 6 is set as a V-shaped structure. A cushion block 16 is installed on the lower surface of the upper template 21, and a limiting column 11 is installed on the upper surface of the lower template 13. The upper end of the limiting column 11 corresponds to the cushion block 16, and the positioning member 9 is made of pure copper with relatively low hardness.

[0038] The cutter head 14 is installed on the positioning plate 20 through the connecting piece 17, and then the three are installed on the connecting plate 19 and the mounting plate 18 as a whole. Since the product 2 is a cast aluminum part, in order to prevent the product 2 from being damaged when pressed, the pressing structure uses the small spring 4 and the large spring 7 to press the product 2. The pressures of the small spring 4 and the large spring 7 need to be large enough to hold down the product 2, and at the same time, it needs to be large enough after pressing to enable the mechanism to rebound smoothly and prevent jamming. Therefore, the small spring 4 and the large spring 7 are used in combination. Since the downward pressing length is relatively large, if only the large spring 7 is used, it will exceed the pressing limit, and if only the small spring 4 is used, the pressing force will be insufficient. The small spring 4 and the large spring 7 are respectively sleeved on the second guide post 27 and the first guide post 26. The third guide post 22 is installed upside down on the mounting plate 18 and is precisely positioned through the hole on the connecting plate 19 and the third guide post 22. The blanking plate 15 is suspended below the pressing structure, and its function is to hold down the product 2 when cutting the waste. The linear bearings - large 25 and the linear bearings - small 24 are installed at the bottom of the blanking plate 15. The function of the linear bearings is to guide the up and down movement of the third guide post 22. The third guide post 22 is fixed below through the retaining ring 23. Washers 1 - 3 and washers 2 - 8 are respectively padded at the bottoms of the small spring 4 and the large spring 7 to level the bottom 6 and prevent deformation and damage when pressing. A mandrel - V6 with a cut middle hole is installed in the middle of the cutter head 14. The front end of the mandrel - V6 is designed as a V shape to prevent the edge of the waste product 2 from being cut and collapsed when the flat cutting force is too large. When in use, after the operator positions and places the product 2 on the positioning part 9, the operator operates the press to press down. When the pressing reaches the contact between the cushion block 16 on the upper template 21 and the limit post 11, it stops. The waste is cut off. Since the headquarters of the mechanism is a hollow structure, the waste falls to the waste collection box at the bottom of the press through the headquarters structure. Since it is not very convenient to adjust the length of the limit post 11 alone, the downward pressing height can be adjusted by adjusting the thickness of the cushion block 16.

[0039] Working principle: When using this cast aluminum rotor waste cutting device, a positioning structure is provided, which can enable the product 2 to be quickly positioned, and then through the cooperation of the small spring 4 and the large spring 7 of the pressing structure, it can be quickly cut, improving the cutting efficiency and increasing the overall practicality.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
