Description

Technical Field

[0001] This application relates to the field of automotive body panel stamping die technology, and more particularly to an automotive body panel stamping die with rapid positioning. Background Technology

[0002] Body panels are thin-walled sheet metal parts that make up the body or cab of a car, covering the engine and chassis, and serving both aesthetic and structural functions. Examples include the hood, inner and outer door panels, fenders, and roof. The function of stamping dies is to use a press to plastically deform the sheet metal within the die cavity, ultimately forming the body panel that meets design requirements.

[0003] When using stamping dies, the positioning of the cover part mainly relies on manual labor. The worker first places the cover part blank on the lower die of the die. Then, using the shallow engraving lines, fixed stop pins / side blocks or special positioning templates preset in the lower die as a reference, the worker visually observes the relative position of the cover part's edge and hole positions with the reference. The worker then pushes the cover part directly by hand or taps the edge lightly with a rubber hammer for fine adjustment. For complex parts, it is necessary to repeatedly compare the fitting gap between the cover part and the template. After confirming that the cover part is visually aligned with the reference, the stamping is started.

[0004] However, manual positioning is slow and can easily lead to longer production cycles. Utility Model Content

[0005] To solve or partially solve the problems existing in the related technologies, this application provides a stamping die for automotive body panels with rapid positioning.

[0024] The above description is merely an optional embodiment of this application and is not intended to limit this application.

[0025] To make the objectives, technical solutions, and beneficial effects of this application clearer, the preferred embodiments of this application will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding by those skilled in the art.

[0026] Example 1: See Figures 1 to 3 A stamping die for automotive body panels with rapid positioning includes a stamping part 1, a top plate 2, a bottom plate 3, a support rod 4, and a mounting plate 5, and further includes: The wedge-shaped guide block 6 is movably disposed on both sides along the length of the mounting plate 5, and the bottom surface of the wedge-shaped guide block 6 slides in contact with the end face of the mounting plate 5; The slide groove 7 is formed on both sides of the width of the mounting plate 5, and a positioning slide rod 8 is slidably connected in it. The bottom of the positioning slide rod 8 is provided with a driving mechanism.

[0027] Specifically, the top plate 2 and the bottom plate 3 are connected by a support rod 4. The stamped part 1 is mounted on the axis of the top plate 2 and located above the mounting plate 5. The mounting plate 5 is fixed to the bottom plate 3 by a support member and is used to place the cover part. The drive mechanism is mounted on the bottom plate 3. The wedge-shaped guide blocks 6 are movably disposed on both sides of the length of the mounting plate 5, and the bottom surface of the wedge-shaped guide blocks 6 slides in contact with the end face of the mounting plate 5 so that the two opposing wedge-shaped guide blocks 6 can move closer or further away from each other. The slide grooves 7 are opened on both sides of the width of the mounting plate 5, and the two slide grooves 7 are arranged opposite each other. Each slide groove 7 is slidably connected to two positioning slide rods 8, and a total of four positioning slide rods 8 can position the cover part. The bottom of the positioning slide rods 8 is provided with a drive mechanism, which is fixed to the bottom plate 3.

[0028] During use, the operator places the automotive body panel to be stamped on the mounting plate 5 and drives the wedge-shaped guide block 6 to move along the length of the mounting plate 5. Because the bottom surface of the wedge-shaped guide block 6 slides in contact with the end face of the mounting plate 5, and the two sets of wedge-shaped guide blocks 6 are set opposite each other, under the power drive, the two sets of wedge-shaped guide blocks 6 approach each other from both sides along the length of the mounting plate 5. When the wedge-shaped structure of the wedge-shaped guide block 6 contacts the body panel, it will push the body panel towards the center of the mounting plate 5 through the guiding force to complete the centering, laying the foundation for subsequent precise positioning. The drive mechanism mounted on the base plate 3 provides power to the positioning slide rod 8; the slide grooves 7 on both sides of the mounting plate 5 in the width direction provide sliding tracks for the positioning slide rod 8. The drive mechanism drives the two sets of positioning slide rods 8 (a total of four sets) in each slide groove 7 to slide along the slide groove 7. The four sets of positioning slide rods 8 respectively come from both sides of the mounting plate 5 in the width direction to fit the edge of the cover in the width direction, clamping and fixing the cover in the aligned position to avoid displacement during stamping. The top plate 2 and the bottom plate 3 are connected by a support rod 4 to form a stable stamping frame; the stamping part 1 at the axis of the top plate 2 moves downward in the vertical direction under the power (such as hydraulic or pneumatic); the stamping part 1 is precisely pressed against the pre-positioned cover part on the mounting plate 5, and the cover part is pressed into the preset shape of the car cover part through the mold cavity.

[0029] Traditional stamping dies rely primarily on manual positioning of the cover parts. Workers first place the cover part blank on the lower die, then use pre-set shallow lines on the lower die, fixed stop pins / side blocks, or a dedicated positioning template as a reference. They visually inspect the relative positions of the cover part's edges and holes to the reference, manually pushing the cover part or lightly tapping the edges with a rubber mallet for fine adjustments. For complex parts, the fit gap between the cover part and the template needs to be repeatedly checked. Once the cover part is visually aligned with the reference, stamping begins. However, manual positioning is slow and can easily extend the production cycle.

[0030] In this application, the wedge-shaped guide block 6 can automatically approach under power drive, and with the guiding effect of the wedge-shaped inclined surface, it can quickly guide the cover to the center of the mounting plate 5, saving the time spent on repeated manual fine-tuning of the center; secondly, the four sets of positioning slide rods 8 in the slide groove 7 are driven by the drive mechanism to slide along the slide groove 7, quickly fitting the edge of the cover to achieve clamping and positioning; the entire positioning process does not require manual intervention, which greatly shortens the time spent on positioning the cover once, thereby avoiding the extension of the production cycle caused by the slow speed of manual operation.

[0031] Example 2: See Figures 1 to 3 Based on Embodiment 1, optionally, the driving mechanism includes: Gear 9 is rotatably mounted in the middle of the base plate 3. Racks 10 are meshed with both sides of gear 9 in the radial direction. A slider 11 is provided at the end of rack 10 away from the base plate 3. A movable seat 12 is provided at the end of slider 11 away from rack 10. The end of movable seat 12 away from slider 11 is connected to positioning slide rod 8.

[0032] Specifically, gear 9 is driven by a motor (not shown in the figure), rack 10 is slidably mounted on base plate 3, slider 11 is fixedly connected to the end of rack 10 away from base plate 3, the end of slider 11 away from rack 10 is fixedly connected to movable seat 12, and the end of movable seat 12 away from slider 11 is fixedly connected to positioning slide rod 8. Thus, the motor drives gear 9 in the middle of base plate 3 to rotate around its own axis. Since the two racks 10 are respectively meshed on the radial sides of gear 9, the rotation of gear 9 will drive the two racks 10 to move synchronously in opposite directions. The end of rack 10 away from base plate 3 transmits power sequentially through slider 11 and movable seat 12, ultimately driving positioning slide rod 8 connected to movable seat 12 to slide along the groove 7 on mounting plate 5, achieving positioning and clamping of the cover. In this application, the precise movement of four positioning slide rods 8 can be achieved with a single motor, ensuring stable positioning accuracy.

[0033] Optionally, the base plate 3 is provided with a slide block 13 along its length, and the slide block 13 is slidably connected to the end of the slider 11 away from the positioning slide rod 8.

[0034] Specifically, the slide block 13 is fixed on the base plate 3 and extends along the length of the base plate 3. The sliding engagement with the slider 11 can strictly limit the movement trajectory of the slider 11 (only moving in a straight line along the length direction), preventing the slider 11 from deviating or tilting due to the lateral force or stamping reaction force transmitted by the rack 10. This ensures that when the slider 11 drives the positioning slide rod 8 through the moving seat 12, the positioning slide rod 8 can slide precisely along the slide groove 7 of the mounting plate 5, ultimately ensuring the accurate positioning of the cover. The sliding engagement between the slide block 13 and the slider 11 can reduce the frictional resistance of the slider 11 during movement, avoid jamming, and ensure efficient power transmission of the gear 9 and rack 10.

[0035] Optionally, the movable seat 12 is provided with support plates 14 on both sides along its length, and the mounting plate 5 is covered on the upper end of the support plates 14.

[0036] Specifically, in Embodiment 1, the support member is a support plate 14, which is fixed on the base plate 3. The support plate 14 supports the mounting plate 5 and stabilizes the mounting plate 5 at a preset height through its own rigid structure. It can not only bear the weight of the mounting plate 5 and the cover, but also bear the vertical pressure transmitted by the stamping part 1 during the stamping process and evenly distribute the load to the base plate 3, while avoiding motion interference of the drive mechanism to the mounting plate 5.

[0037] Optionally, the base plate 3 is fixed with mounting seats 15 on both sides along its length, and the mounting seats 15 are provided with a first electric telescopic rod 16, the movable end of the first electric telescopic rod 16 being connected to the wedge-shaped guide block 6.

[0038] Specifically, the mounting base 15 provides a rigid mounting carrier for the first electric telescopic rod 16, preventing the telescopic rod from swaying or shifting due to reaction force during telescopic movement, ensuring that its axis is consistent with the movement direction of the wedge-shaped guide block 6 (the length direction of the mounting plate 5), and laying a stable driving foundation; the movable end of the first electric telescopic rod 16 is connected to the wedge-shaped guide block 6, and the position of the guide block can be precisely adjusted through telescopic movement, improving the consistency and accuracy of the alignment of the cover.

[0039] Optionally, the gear 9 is provided with a second electric telescopic rod 17 along its axial direction, and the mounting plate 5 has a hole at its axis that allows the movable end of the second electric telescopic rod 17 to pass through, so that the movable end of the second electric telescopic rod 17 can rotate and pass through the hole.

[0040] Specifically, the second electric telescopic rod 17 is installed on the gear shaft. After stamping, the second electric telescopic rod 17 extends and lifts the formed cover from below, assisting the operator to quickly remove the part and shorten the removal time.

[0041] Optionally, a third electric telescopic rod 18 is installed at the axis of the top plate 2, and the movable end of the third electric telescopic rod 18 is connected to the stamping part 1.

[0042] Specifically, as the direct driving source of the stamping action, the third electric telescopic rod 18 can drive the stamping part 1 to move precisely in the vertical direction through the telescopic action. When it extends, it pushes the stamping part 1 downward to apply pressure and complete the stamping of the cover. When it shortens, it pulls the stamping part 1 upward to reset and detach it from the cover to avoid the space for taking out the part.

[0043] It should be noted that the structures and / or installation methods not detailed in this application are those that can be known by those skilled in the art in combination with common knowledge and / or prior art, and are not the focus of this application, and will not be elaborated further here.

[0044] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
