When the sunroof frame body is placed in the upper die profiling cavities and the lower die profiling cavities, the burrs on the inner mouth edge of the sunroof frame body are folded downward by the upper die and the lower die clamping extrusion.

[0006] Further, the upper die profiling cavities are provided with extrusion grooves for extruding the inner mouth edge, one side of the extrusion groove has a profiling surface for abutting the upper surface of the sunroof frame body, and the other side has a downward pressing surface for directly pushing the burrs to fold.

[0007] Further, the downward pressing surface is an arc surface so as to push the burrs to fold in a rounded corner shape.

[0008] Further, the lower die profiling cavities are provided with a supporting step for abutting the lower side of the inner mouth edge, and the supporting step is the positioning reference of the sunroof frame body.

[0009] Further, the upper die is fixed to the bottom of the pressing plate, the lower die is fixed to the base, the base and the pressing plate are connected through a guide mechanism, and the pressing plate is driven by the guide mechanism to approach / far away from the base along the vertical direction.

[0010] Further, the guiding mechanism is any one of a pneumatic or hydraulic mechanism.

[0011] The utility model discloses the beneficial effect lies in:

[0012] The burr processing frock for skylight frame body provided by the utility model changes the direction of burr extension through up and down mold closing frock and forms a fillet at the inner mouth edge of skylight frame body to avoid scratching the passenger, and the subsequent burr polishing work can be implemented with the inner mouth edge as a reference, thereby reducing construction difficulty and preventing the formation of a wavy edge.

[0019] In the description of the utility model, it needs to be explained that the orientation or position relation indicated by the terms "upper", "lower", "left", "right", "inner", "outer" and the like is based on the orientation or position relation shown in the drawings, and the above description is simplified for the convenience of describing the utility model, and does not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as the limitation of the utility model.

[0020] The singular form "a", "said" and "the" used in the specification contains plural form unless it is clearly indicated, and the words "include", "contain" and "have" used in the specification indicate the existence of the claimed characteristics, but do not exclude the existence of one or more other characteristics.

[0021] The exemplary embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood, however, that the application can be presented in many different forms and are not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all the drawings, the same reference numerals represent the same or functionally similar elements.

[0022] Figure 2 and Figure 3 The overall structure of the burr processing tool for the sunroof frame is shown, mainly including the lower die 40 arranged on the base 21 and the upper die 50 arranged on the lower side of the pressing plate 22, and at least three guide mechanisms 30 arranged between the base 21 and the pressing plate 22 to control the vertical lifting of the pressing plate 22 relative to the base 21, thereby realizing the opening and closing of the upper die 50 relative to the lower die 40.

[0023] Figure 4 and Figure 5 The partial structure of the mold when the mold is closed is shown. The lower side of the upper die 50 is provided with an upper die profiling cavity 51 for substantially conforming to the upper surface 13 of the sunroof frame 10, and the upper side of the lower die 40 is provided with a lower die profiling cavity 41 for substantially conforming to the lower surface 11 of the sunroof frame 10. Since the inner lip edge 12 of the sunroof frame 10 extends obliquely from the outer side of the frame inwardly and upwardly, a supporting step 42 is correspondingly arranged in the lower die profiling cavity 41 for contacting the lower side of the inner lip edge 12, and the supporting step 42 is close to the processing site and can be used as the main positioning during the processing of the sunroof frame 10. The position of the inner lip edge 12 in the upper die profiling cavity 41 is provided with an extrusion groove 52, one side of the extrusion groove 52 has a profiling surface 53 that conforms to the upper surface of the inner lip edge 12 when the upper die 50 is pressed down, and the other side has a pressing surface 54 that directly acts on the inner lip edge 12 to extrude and fold the edge burr downward. Further, the pressing surface 54 and the extrusion groove 52 form a downwardly curved arc surface as a whole, so that the burr is pushed downward to form a rounded edge during the extrusion of the burr. After the burr is folded, the tool is used to polish and remove the burr along the inner lip edge 12.

[0024] In one embodiment, an auxiliary positioning step 43 shaped like the sunroof frame 10 can be arranged on the outer side edge of the lower die profiling cavity 41, which is used together with the main positioning in the positioning system.

[0025] In another embodiment, the guide mechanism 30 can be any one of a pneumatic or hydraulic drive mechanism.
