Description

Technical Field

[0001] The invention relates to the field of trimming of blister plastic parts, in particular to a trimming device for producing automobile blister plastic parts. Background Art

[0002] With the global push for sustainable development, the automotive industry is not immune from its environmental responsibilities. Compared to other manufacturing methods, thick sheet blistering can be more energy-efficient, thereby reducing the overall carbon footprint of automotive production.

[0003] Roof luggage boxes are common auto parts. Currently, the upper and lower parts of roof luggage boxes are generally produced by blister forming. After production, they are assembled after trimming, grinding, painting and other processes. After the blister parts of the roof luggage boxes are produced and cooled, for thicker plastics, a trimming knife is generally used to reciprocate multiple times to cut off a circle of plastic around them. It is currently difficult to control the amount of cutting of the trimming knife each time. Too deep a cutting depth will affect the smooth movement of the trimming knife, resulting in an uneven edge of the blister body, and the debris generated by reciprocating multiple times will also reduce the trimming accuracy of the trimming knife. Currently, it is necessary to repeatedly adjust the position of the blister body so that the blister body can be accurately aligned with the trimming knife. During the trimming process, the blister body is also prone to displacement, which will further reduce the trimming accuracy of the blister body. Summary of the invention

When the sliding frame 5 moves toward the direction away from the blister body 6, it drives the sliding frame 11, the compression spring 12 and the pressing frame 13 to move upward, and the pressing frame 13 no longer presses the edge of the blister body 6 that needs to be cut off.

[0049] When the sliding frame 5 moves toward the direction approaching the blister body 6, it drives the pressing frame 14 and the vertical spring 15 to move downward. Under the action of the vertical spring 15, the pressing frame 14 can be closely attached to and pressed against the middle part of the blister body 6. When the sliding frame 5 moves in the direction away from the blister body 6, it drives the pressing frame 14 and the vertical spring 15 to move upward. The pressing frame 14 no longer presses the middle part of the blister body 6. The pressing frame 13 is closely attached to and pressed against the edge that needs to be cut off on the blister body 6, and then the middle part of the blister body 6 is closely attached to and pressed against by the lower pressing frame 14. In this way, the displacement of the blister body 6 during the trimming process and the resulting scrapping can be reduced, thereby further improving the trimming accuracy of the blister body 6 by the trimming knife 76.

[0050] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
