Description

Technical Field

[0001] This application belongs to the field of automotive stamping die technology, specifically relating to a wedge flanging mechanism. Background Technology

[0002] With the continuous development of the automobile industry, the number of automobile models is increasing, and the assembly process of the body-in-white is becoming more and more complex. Many exterior body panels, such as side panels, fenders, roofs, and hood panels, have negative angle flanges to increase the clamping force of the stamped parts and improve the body strength. However, the negative angle flanges on body parts correspondingly increase the complexity of the mold structure. To smoothly remove the stamped parts after the negative angle flange forming is completed, a slider-type wedge mechanism is generally used in the mold structure. The wedge mechanism is a mechanical mechanism that transforms vertical motion into horizontal or inclined motion through the cooperation of a wedge and a slider. It converts the vertical force of the machine tool into an inclined force. In other words, the die portion with the negative angle flange forming is made into a trolley mechanism. After the side flange forming is completed, the die and the trolley retract together to a certain distance from the inner edge of the negative angle of the stamped part, allowing the stamped part to be easily removed.

[0003] When machining complex parts, adjusting the angle of the wedge mechanism mold is quite complicated and requires certain modifications to the mold structure. It cannot achieve automated and mechanized operation, resulting in the consumption of more human resources and reduced machine efficiency. Furthermore, traditional machining methods have certain technical requirements for operators and are somewhat dangerous. Summary of the Invention

[0031] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

Figure 2 As shown, the workpiece to be processed is a vehicle roof 100. The roof 100 has pre-drilled holes for installing windows. The side of the roof 100 is a first processing edge 110 to be flanged, and the window holes have a second processing edge 120 to be flanged. The flange angles of the first processing edge 110 and the second processing edge 120 are different. Figure 1 and Figure 3As shown, the wedge flanging mechanism is used to flanging a workpiece on a stamping die. The flanging mechanism includes: a first wedge assembly 200, which is slidably connected to the lower die 720 of the stamping die in a first direction, and the first wedge assembly 200 is used to abut against the first processing edge 110 of the workpiece; the first direction is angularly set to the stamping direction of the stamping die; and a first flanging assembly 300, which is slidably connected to the upper die 710 of the stamping die in a first direction, and the first flanging assembly 300 is used to abut against the first processing edge 110 of the workpiece. A first processed edge 110 on a wedge assembly 200 is flanged; a second wedge assembly 400 is slidably connected to the first wedge assembly 200, and the second wedge is used to abut against the second processed edge 120 in a second direction; a second flange assembly 500 is slidably connected at one end to the second wedge assembly 400 in a second direction, and the other end of the second flange assembly 500 is located above the second processed edge 120; an upper die drive assembly 600 is fixedly connected to the upper die 710 of the stamping die, so as to be driven by the upper die 710. The upper die 710 moves along the stamping direction. The upper die transmission assembly 600 is provided with a first transmission member 610, a second transmission member 620, and a third transmission member 630. Along the stamping direction, the first transmission member 610 and the second transmission member 620 are at the same position and both are lower than the third transmission member 630. During the first stroke of the upper die 710 moving along the stamping direction, the first transmission member 610 moves to abut against the side of the first wedge assembly 200, thereby pushing the first wedge assembly 200 to move to abut against the first processing edge 110. The abutting position; the second transmission member 620 moves to abut against the side of the second wedge assembly 400 to push the second wedge assembly 400 relative to the first wedge assembly 200 to abut against the second processing edge 120; during the second stroke of the upper die 710 moving along the stamping direction, the third transmission member 630 drives the second flanging assembly 500 to move relative to the first wedge assembly 200 to flang the second processing edge 120, while the first flanging assembly 300 simultaneously flangs the first processing edge 110. By setting a second wedge assembly 400 on the first wedge assembly 200 and a second flap 510 assembly on the second wedge assembly 400, when the upper mold 710 is pressed down, the first processing edge 110 of the workpiece to be processed can be flapped in the first direction and the second processing edge 120 of the workpiece to be processed can be flapped in the second direction. Under the condition of limited space, the two completely different wedge flapping actions in two directions can be completed, which simplifies the process of the part and makes the mold more efficient. The process is simplified and the number of molds for the part is reduced. The structure of this mechanism is compact and easy to install, which greatly reduces the mold development cost and improves the mold production efficiency.

[0033] In some embodiments, both the first direction and the second direction are perpendicular to the stamping direction of the stamping die, and the first direction and the second direction are at an angle to each other. In other embodiments, the mounting position and mounting angle of the second wedge assembly 400 can be adjusted to achieve simultaneous flanging of various multi-angle wedges.

[0050] In some embodiments, the first transmission member 610, the second transmission member 620, and the third transmission member 630 protrude toward the stamping direction relative to the upper die 710; the first transmission member 610 and the second transmission member 620 are transmission guide plates. During the first stroke, when the first transmission member 610 pushes the first filler 220 to abut against the first processing edge 110, the side of the first transmission member 610 slides relative to the side of the first filler 220, without obstructing the downward pressing of the upper die 710; when the second transmission member 620 pushes the second drive member 410 to abut against the second processing edge 120, the side of the second transmission member 620 slides relative to the side of the second drive member 410, without obstructing the downward pressing of the upper die 710; the third transmission member 630 is a transmission casting, and the tilt angle of the bottom of the third transmission member 630 is the same as the tilt angle of the third drive guide plate 520. The third transmission member 630 directly drives the second flip plate 510 assembly to flip the plate. Two first transmission members 610 are provided. By providing two first transmission members 610, the force on the first transmission member 610 when driving the first filler 220 is more even. In other embodiments, the first transmission member 610 may also be provided as three, four or more.

[0051] The second aspect of this embodiment provides a method for processing a wedge flange mechanism, the method comprising the following steps:

[0052] S1: Place the top cover 100 to be processed into the mold;

[0053] S2: The upper die 710 moves along the stamping direction into the first stroke, and the first transmission member 610 moves to abut against the side of the first filler 220 to push the first filler 220 to abut against the first processing edge 110; the second transmission member 620 moves to abut against the side of the second driving member 410, and the second driving member 410 pushes the second filler 420 relative to the first wedge assembly 200 to abut against the second processing edge 120.

[0054] S3: The upper die 710 continues to move along the stamping direction into the second stroke. The third transmission member 630 abuts against the third drive guide plate 520 to drive the second flip plate 510 to move relative to the first wedge assembly 200, and cooperate with the second filler 420 to flip the second processed edge 120. The first flip plate 320 presses down and cooperates with the first filler 220 to flip the first processed edge 110, thus completing the simultaneous flipping of the first processed edge 110 and the second processed edge 120.

[0055] S4: The upper mold 710 retracts, the first flap 320 disengages from the first filler 220, the third transmission component 630 disengages from the second flap 510, and the second flap 510 rebounds under the spring force of the third retraction spring 540 until it abuts against the third stop block 225 to reset.

[0056] S5: The upper mold 710 continues to retract to its reset position. The second transmission component 620 disengages from the second drive component 410. Under the spring force of the first return spring 414, the second drive component 410 rebounds to retract and abut against the second stop block 224. The second filling component abuts against the first stop block 223 under the spring force of the second return spring 424. The first transmission component 610 disengages from the first filling component 220. The first filling component 220 retracts under the drive of the return spring on the lower mold 720 and abuts against the stop block on the lower mold. At this time, the first wedge component 200 and the second wedge component 400 on the lower mold 720 have completed their retraction. The part is removed, and the processing is completed.

[0057] The processing method in this application completes two completely different wedge flanging actions under limited space, which simplifies the process of the workpiece and makes the mold more efficient. The simplified process reduces the number of molds required for the workpiece. The mechanism is compact and easy to install, which greatly reduces the mold development cost and improves the mold production efficiency. At the same time, by setting a return spring, the wedge automatically resets after processing, and the workpiece can be directly removed, which is convenient for processing and simplifies the processing steps.

[0058] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0059] This application discloses a wedge flanging mechanism. By setting a second wedge assembly on a first wedge assembly and a second flap assembly on the second wedge assembly, when the upper die is pressed down, the first edge of the workpiece to be processed can be flanged in a first direction, and the second edge of the workpiece to be processed can be flanged in a second direction. This allows for the completion of two completely different wedge flanging actions in a space-constrained environment, simplifying the process steps of the workpiece and making the mold more efficient. The simplified process reduces the number of molds required for the workpiece. The mechanism has a compact structure, is easy to install, greatly reduces mold development costs, and improves mold production efficiency.
