[0007] Compared with prior art, the stripper of the permanent magnet rotor punching piece magnetic steel waste of the utility model prevents adhesion during operation by setting anti-adhesion unit. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 It is the sectional structure schematic diagram in the stripper of the permanent magnet rotor punching piece magnetic steel waste of the utility model.

[0009] In the diagram, 1 is the stripper block; 2 is the mounting post; 3 is the upper convex ring; 4 is the lower convex ring; 5 is the spring; and 6 is the stripper sleeve. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] like Figure 1 As shown, the descraping device for scrap permanent magnet rotor laminations includes a descraping block 1. The lower end face of the descraping block 1 has several axially recessed holes. A descraping assembly is connected to the descraping block 1 at the recessed holes to prevent laminations from adhering to the descraping block 1. This descraping assembly includes an anti-sticking unit to prevent lamination adhesion and a mounting unit connected to the descraping block 1 and cooperating with the anti-sticking unit. The mounting unit includes a mounting column 2. 2. An upper protruding ring 3 with a radially outward protrusion and a thread is provided on the outer peripheral wall of the inner end, and a lower protruding ring 4 with a radially outward protrusion and an outer diameter smaller than the outer diameter of the upper protruding ring 3 is provided on the outer peripheral wall of the outer end of the mounting post 2. The inner end of the recessed hole is provided with a thread that mates with the upper protruding ring 3. After the upper protruding ring 3 and the stripping block 1 are connected by threads, a gap is left between the inner wall of the upper protruding ring 3 and the inner wall of the recessed hole. The lower end face of the mounting post 2 is flush with the lower end face of the stripping block 1.

[0012] In the aforementioned device for removing scrap permanent magnet rotor laminations, the anti-sticking unit includes a spring 5 and a stripping sleeve 6. Both the spring 5 and the stripping sleeve 6 are sleeved on the mounting post 2, and the two ends of the spring 5 respectively abut against the upper convex ring 3 and the stripping sleeve 6. The inner wall of the stripping sleeve 6 is provided with a radially inward protrusion, which cooperates with the lower convex ring 4 and prevents it from detaching from the inner convex ring of the mounting post 2. The inner convex ring is in sliding cooperation with the mounting post 2. When pressed down, the stripping sleeve 6 retracts into the recessed groove through the laminations. When it is lifted, the spring 5 controls the stripping sleeve 6 to reset, thereby separating the adhered laminations.

[0013] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0014] Although this document uses terms such as "etc." extensively, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
