Description

Technical Field

[0001] The utility model relates to the field of stamping dies, in particular to a stamping die for a vacuum cleaner impeller. Background Art

[0002] The impeller refers to the wheel with moving blades, which is a component of the impulse turbine rotor. It can also refer to the general term for the wheel and the rotating blades installed on it. The impeller can be classified according to its shape and opening and closing conditions. The upper cover of the impeller is mostly formed by stamping, and then docked with the lower cover and impeller plate. The stamping die is a special process equipment for processing materials into parts in cold stamping. Stamping is performed at room temperature using a die installed on a press to apply pressure to the material to cause separation or plastic deformation.

[0003] However, since the raised position of the cover plate after stamping and flanging will be limited and stuck inside the perforation of the mold, it is often necessary to use rods to lift the material when unloading, which can easily cause damage to the components at the lifted position. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a vacuum cleaner impeller stamping die, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a vacuum cleaner impeller stamping die, comprising a stamping die, the stamping die comprising an upper die and a lower die, a mold being installed on the upper surface of the lower die, a discharge hole being provided on one side of the die, a discharge hole being provided on the side of the die away from the discharge hole, a stamping hole being provided on the upper surface of the die, a picking mechanism being installed at a position corresponding to the stamping hole inside the discharge hole, the picking mechanism comprising: an arc-shaped baffle and a pull rod, a hook rod being provided below the arc-shaped baffle, limiting sliders being installed on both side ends of the arc-shaped baffle, a movable slide being provided on the outer side of the limiting slider located inside the discharge hole.

[0006] As a further solution of the present invention: a limiting guide rail is installed below the hook rod and located on the outside of the mold, and a rotating ear plate is provided on the outside of the hook rod and located on the lower surface of the arc baffle.

[0007] As a further solution of the present invention: a reset rod is installed on the lower surface of the upper die at a position corresponding to the punching hole, and a guide rod is connected between the upper die and the lower die.

[0008] As a further solution of the present invention: the arc-shaped baffle is connected to the movable sliding groove in a limited sliding manner through the limiting sliding block, and the pull rod is fixedly connected to the arc-shaped baffle.

[0009] As a further solution of the present invention: the material discharge perforation and the material discharge perforation are arranged through each other, and the punching hole and the mold are arranged through each other.

[0010] As a further solution of the present invention: an elastic rotating shaft is connected between the hook rod and the rotating ear plate.

[0011] As a further solution of the present invention: the discharge perforation is a T-shaped structural component.

[0012] As a further solution of the present invention: a punching head is installed at the lower end of the reset rod, and the upper die is movably connected to the guide rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] After the stamping is completed and reset, the hook rod will be reset upward under the reset action of the elastic rotating shaft. Then, by pulling the pull rod outward, the raised position of the hook rod will hook the cover plate flange and pull it outward to unload the material, and the formed cover plate will be taken out from the discharge perforation position.

[0015] The arc-shaped baffle on the material-retrieving mechanism is pushed toward the inner position of the mold through the limiting slider under the action of the moving slide groove, so that the arc-shaped baffle moves to the innermost position as a whole. Then, the inner side of the arc-shaped baffle and the punching hole form a complete arc as a whole, which can ensure the stamping forming of the cover plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-5 As shown, this embodiment provides a vacuum cleaner impeller stamping die, including a stamping die 1, the stamping die 1 includes an upper die 2 and a lower die 3, the upper surface of the lower die 3 is installed with a die 6, one side of the die 6 is provided with a discharge perforation 8, the die 6 is located on the side away from the discharge perforation 8 and is provided with a discharge perforation 9, the discharge perforation 9 is a T-shaped structural component, the discharge perforation 8 and the discharge perforation 9 are arranged through, the upper surface of the die 6 is provided with a stamping hole 7, the stamping hole 7 and the die 6 are arranged through, and the inside of the discharge perforation 9 corresponds to the position of the stamping hole 7. It is equipped with a material picking mechanism 10, which includes: an arc-shaped baffle 1001 and a pull rod 1004. The pull rod 1004 is fixedly connected to the arc-shaped baffle 1001. A hook rod 1003 is provided below the arc-shaped baffle 1001. The hook rod 1003 is an L-shaped structural component. Limiting sliders 1002 are installed on both side ends of the arc-shaped baffle 1001. The outer side of the limiting slider 1002 is located inside the discharge perforation 9 and a movable slide groove 902 is provided. The arc-shaped baffle 1001 is slidingly connected to the movable slide groove 902 through the limiting slider 1002.

[0024] like Figure 2-3 As shown, in this embodiment, a limiting guide rail 901 is installed on the outside of the mold 6 below the hook rod 1003, and a rotating ear plate is provided on the lower surface of the arc baffle 1001 on the outside of the hook rod 1003. An elastic rotating shaft is connected between the hook rod 1003 and the rotating ear plate. A reset rod 5 is installed at the position of the punching hole 7 corresponding to the lower surface of the upper die 2, and a punching head is installed at the lower end of the reset rod 5. A guide rod 4 is connected between the upper die 2 and the lower die 3, and the upper die 2 is movably connected to the guide rod 4.

[0025] The working principle of the present invention is as follows: when in use, the arc baffle 1001 on the material taking mechanism 10 is pushed to the inner position of the mold 6 through the limiting slider 1002 under the action of the moving slide 902, so that the arc baffle 1001 is moved to the innermost position as a whole. Then, the inner side of the arc baffle 1001 and the punching hole 7 form a complete arc as a whole. After the cover plate to be punched is filled into the interior of the mold 6 through the position of the discharge perforation 8, the upper die 2 is guided above the guide rod 4 and then moved downward as a whole, so that the punch at the lower end of the reset rod 5 is pressed. After the punching head passes through the punching hole 7 as a whole and contacts the cover plate, the punching head will contact the hook rod 1003 after punching, and push the hook rod 1003 to rotate and be stored inside the material-taking mechanism 10 under the action of the elastic rotating shaft by using the ear plate. When the punching head continues to move downward, the cover plate will pass through as a whole and then be flanged downward. After resetting after punching, the hook rod 1003 will be reset upward under the resetting action of the elastic rotating shaft. Then, by pulling the pull rod 1004 outward, the raised position of the hook rod 1003 will hook on the flange of the cover plate and pull it outward to unload, and the formed cover plate will be taken out from the position of the discharge perforation 9.
