[0031] The following further describes the present utility model in detail with reference to the accompanying drawings:

[0032] As Figure 1 shown, the present utility model provides a tooling anti-pinch mechanism, including:

[0033] A top protection plate 1, which includes a connected front top protection plate 11 and a rear top protection plate 12; the front top protection plate 11 is installed at the top end of the door panel tooling 4, and one end of the rear top protection plate 12 is connected to the front top protection plate 11, and the other end extends a certain distance towards the rear side of the door panel tooling 4;

[0034] A side protection plate 2, which is located beside the door panel tooling 4;

[0035] A rear anti-pinch plate 3, which is located at the rear side of the door panel tooling 4; a plurality of notches 31 are formed at the bottom of the rear anti-pinch plate 3, thereby forming a flexible contact portion 32, and the flexible contact portion 32 is used to contact the roller 5 of the moving door panel tooling 4;

[0036] Among them, the top protection plate 1, the side protection plate 2, and the rear anti-pinch plate 3 form a three-sided enclosing structure.

[0037] Preferably, the rear pinch - proof plate 3 is spaced from the end of the door panel tooling 4 by a certain distance.

[0038] The top protection plate 1, the side protection plates 2, the rear pinch - proof plate 3 and the door panel tooling 4 enclose a buffer space.

[0039] Preferably, the top of the side protection plate 2 is fixedly connected to the left or right side wall of the rear top protection plate 12.

[0040] The top of the rear pinch - proof plate 3 is fixedly connected to the rear side wall of the rear top protection plate 12.

[0041] The side wall of the side protection plate 2 abuts against the side wall of the rear pinch - proof plate 3.

[0042] Preferably, a top hole 111 is installed on the front top protection plate 11, and after the bolt passes through the top hole 111, the front top protection plate 11 is fixed to the top end of the door panel tooling 4.

[0043] Preferably, the flexible contact part 32 is strip - shaped.

[0044] Preferably, the length of the notch 31 is half of the length of the rear pinch - proof plate 3.

[0045] Preferably, the front top protection plate 11 and the rear top protection plate 12 are integrally formed.

[0046] Preferably, both the side protection plate 2 and the rear pinch - proof plate 3 are polyurethane plates.

[0047] To better illustrate the technical effects of the present invention, the present invention provides the following specific embodiments to illustrate the above - mentioned technical processes:

[0048] Embodiment 1: A tooling anti - pinch mechanism, as Figure 2 shown, includes a three - sided enclosing structure composed of a top protection plate 1, side protection plates 2 and a rear pinch - proof plate 3.

[0049] A hole is opened above the top protection plate 1 to form a top hole 111. After the bolt passes through the top hole 111, the front top protection plate 11 is fixed to the top end of the door panel tooling 4 to realize the positioning of this mechanism.

[0050] The anti - pinch mechanism is made of polyurethane material as a whole. When the material softens, it is beneficial for employees to detect when they accidentally touch it.

[0051] A number of notches 31 are opened at the bottom of the rear pinch - proof plate 3, thus forming a strip - shaped flexible contact part 32. The flexible contact part 32 is used to contact the roller 5 of the moving door panel tooling 4; part of the material of the rear pinch - proof plate 3 is removed, which is equivalent to local softening treatment. When the operator accidentally touches it, there is a feeling of touch, but will not be pinched.

[0052] The rear pinch protection plate 3 is spaced from the end of the door panel tooling 4 by a certain distance. The top protection plate 1, the side protection plates 2, the rear pinch protection plate 3 and the door panel tooling 4 enclose a buffer space, which is a structure with a hollow interior. Even if a person accidentally touches it, there is still space between the hand and the roller 5 and the tooling, and the hand will not be pinched.

[0053] The utility model can prevent the operator's hand from accidentally entering the gap between the chain and the tooling, causing personal injury. The utility model increases the external buffer space. When the operator accidentally touches it, there is no risk of pinching. The mechanism of the utility model adopts a soft material, which can give a tactile reminder to the operator when accidentally touched.

[0054] Example 1:

[0055] For the interior trim requirements of the Mercedes instrument (model 214) and other automotive interior manufacturing fields, the door panel tooling 4 is placed above the line conveyor chain. Through the rotation of the line chain, the plastic roller 5 rubs against the door panel tooling 4, thereby driving the upper door panel tooling 4 to move. This structure is mainly to prevent the operator's hand from accidentally touching the part between the roller 5 and the tooling, causing a risk of pinching.

[0056] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any change or replacement within the technical scope disclosed by the utility model should be covered by the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claimed rights.
