Description

A mold mechanism for flanging and side forming of automotive stamping parts Technical Field

[0001] This utility model relates to the field of automotive cold stamping die technology, specifically to a die mechanism for flanging and side shaping of automotive stamping parts. Background Technology

[0002] In automotive cold stamping production, the flanges in the automotive stamping part shown in Figure 1 are to be flanged and side-shaped to form the automotive stamping part shown in Figure 2. Traditional processes typically divide flanging and side-shaping into two separate steps, increasing the number of stamping steps, production cycle, and mold costs. To meet the automotive industry's demand for cost reduction and efficiency improvement, innovative mold mechanisms are needed to reduce the number of processes. Summary of the Invention

[0003] The purpose of this invention is to provide a mold mechanism for flanging and side shaping of automotive stamping parts, which solves the shortcomings of existing technology where flanging and side shaping are two separate processes.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A mold mechanism for flanging and side shaping of automotive stamping parts includes an upper mold and a lower mold for processing automotive stamping parts that are L-shaped in shape. The automotive stamping parts include a flanging section and a non-processing section. The flanging section has a flap to be flanged. The lower mold is provided with a station for the flanging section and a shaping mechanism provided on the side of the station to complete the flanging and side shaping of the automotive stamping parts in one step.

[0006] The shaping mechanism includes a guide block set on the workstation side, and a flange insert, a slider, a drive block, and a reset component for controlling the resetting of the flange insert arranged sequentially along the direction of the guide block; one side of the flange insert abuts against the wing piece to be flanged, and the other side abuts against the slider. The flange insert and the slider abut against each other and slide together on the guide block. The drive block is set between the reset component and the slider.

[0007] The upper mold is provided with a bottom block that extends from the upper mold to the lower mold. The lower end of the bottom block abuts against the upper end of the drive block and squeezes the drive block to move downward.

[0008] The bottom of the side of the flanged insert that abuts against the wing to be flanged is a shovel-shaped part extending towards the bottom of the wing, and this shovel-shaped part of the flanged insert transitions in an arc shape with the side edge on the same side.

[0009] The slider is in the shape of a right trapezoid, and its hypotenuse and the reset component form the sliding space of the drive block. The drive block is in the shape of a right trapezoid, and the inclined surface of the drive block abuts against the inclined surface of the slider.

[0010] The reset component includes a fixed plate vertically mounted on the lower mold and a reset spring, which is connected to the slider.

[0011] The upper mold is equipped with a flange limiting block, which extends from the upper mold to the lower mold. The flange limiting block and the flange insert are clamped on both sides of the flanged wing.

[0012] The length of the bottom block of the upper mold is adjustable.

[0013] The advantages of this utility model are: 1. This utility model can complete the flanging and side shaping in one step, which simplifies the process, saves time, and saves mold costs; 2. The bottom block set in the upper mold can convert the downward pressure of the upper mold into the driving force of the driving block, and the side shaping angle can be accurately adjusted by adjusting the length of the bottom block; 3. The flanging limit block set in the upper mold can ensure the accuracy of the wing flap flanging angle. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent.

[0021] To simplify the description of this embodiment, some components that are well-known to those skilled in the art but are not related to the main content of this invention may be omitted in the accompanying drawings or description. Additionally, for ease of description, some components in the drawings may be omitted, enlarged, or reduced, but these do not represent the actual product dimensions or the complete structure.

[0022] This utility model discloses a mold mechanism for flanging and side shaping of automotive stamping parts, used to process the automotive stamping part 1 shown in Figure 1 into the automotive stamping part 1 shown in Figure 2.

[0023] As shown in Figures 3 and 4, it includes an upper die A and a lower die B, used to process an L-shaped automotive stamping part 1. As shown in Figures 1 and 2, the automotive stamping part 1 includes a flanging section 11 and a non-processing section 12. The flanging section 11 has a flap 111 to be flanged. The lower die B is provided with a station for the flanging section 11, and a forming mechanism provided on the station side to complete the flanging and side forming of the automotive stamping part 1 in one step.

[0024] As shown in Figure 3, the shaping mechanism includes a guide block 2 disposed on the workstation side, and a flange insert 3, a slider 4, a drive block 5, and a reset member for controlling the reset of the flange insert 3 arranged sequentially along the direction of the guide block 2; one side of the flange insert 3 abuts against the wing piece 111 to be flanged, and the other side abuts against the slider 4. The flange insert 3 and the slider 4 abut against each other and slide together on the guide block 2. The drive block 5 is disposed between the reset member and the slider 5.

[0025] Furthermore, as shown in Figure 4, the slider 4 is in the shape of a right trapezoid, and its hypotenuse and the reset member form a sliding space for the drive block 5. Correspondingly, the drive block 5 is in the shape of a right trapezoid, and the inclined surface of the drive block 5 abuts against the inclined surface of the slider 4.

[0026] The reset component includes a fixed plate 61 vertically mounted on the lower mold B and a reset spring 62, which is connected to the slider 4. After the machining process is completed, the reset spring 62 resets the slider 4.

[0027] The upper mold A is provided with a bottom block 7, which extends from the upper mold A to the lower mold B. The lower end of the bottom block 7 abuts against the upper end of the drive block 5 and presses the drive block 5 to move downward.

[0028] When processing automotive stamping part 1, the upper die A moves to the lower die B, pressing the drive block 5 downwards against the bottom block 7, pressing the slider 4 against the flanging insert 3, thereby pushing the flanging insert 3 against the wing 111, and then folding the wing 111 in the horizontal direction upwards along the side of the flanging insert 3 until it is folded to a preset angle. The upper die A continues to press down on the lower die B, and the flanging insert 3 pushes the flanging processing section 11 of the automotive stamping part 1 for side shaping. The upper die A and the lower die B close together, and the side shaping is completed.

[0029] Preferably, referring to Figures 5 and 4, the bottom of the side of the flanged insert 3 that abuts against the wing 111 to be flanged is a shovel-shaped portion 31 extending towards the bottom of the wing 111, and this shovel-shaped portion 31 of the flanged insert 3 transitions to the side edge 32 on the same side in an arc shape. When the flanged insert 3 is pressed against the wing 111, the shovel-shaped portion 31 extends into the bottom of the wing 111, and the wing 111 folds upward along the arc transition between the shovel-shaped portion 31 and the side edge 32. This design allows for a smoother flanged flange of the wing 111.

[0030] To ensure the accuracy of the flanging angle, as shown in Figure 4, a flanging limiting block 8 is set on the upper mold A. The flanging limiting block 8 extends from the upper mold A to the lower mold B. When the upper mold A moves to the lower mold B, the flanging limiting block 8 and the flanging insert 3 are located on both sides of the wing 111 respectively. After the flanging is completed, the flanging limiting block 8 and the flanging insert 3 are clamped on both sides of the flanged wing 111. This can ensure that the wing 111 will not be over-folded.

[0031] The side forming angle of the automotive stamping part 1 depends on the distance the flanging insert 3 moves, which in turn depends on the distance the driving block 5 is pressed downward by the bottom block 7, and ultimately on the length of the bottom block 7. Therefore, in order to accommodate the different requirements of the automotive stamping part 1 for the side forming angle, the length of the bottom block 7 of the upper die A is adjustable.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made within the scope of the claims of this utility model should be considered within the technical scope of this utility model.
