Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and specifically to a shaping device applied to a navigation host mounting bracket. Background Technology

[0002] As automobiles become increasingly sophisticated, the requirements for automotive parts are also rising. These requirements extend beyond the quality of the parts themselves to include stricter control over the manufacturing process. Currently, the manufacturing of automotive door hinge components typically employs single-die stamping, meaning each process requires a separate die. For example, punching requires a specialized punching die, trimming requires a specialized trimming die, bending requires a specialized bending die, side shearing requires a specialized die, and shaping requires a specialized shaping die. Deburring, on the other hand, is done manually. This results in a large number of stamping presses and workers, more safety accidents, a high product defect rate, low efficiency, and high die development costs.

[0003] For example, patent document with patent application number 201821774746.8 and publication date of June 11, 2019 discloses a continuous stamping die for automobile door hinges. The upper die base and the lower die base are provided with a punching positioning hole part, a trimming part, a deburring part, a bending forming part, a side half-shearing part, a punching part and a shaping part in sequence according to the product processing order. The trimming part includes a lower die cutting edge and a trimming punch. The trimming punch is installed in the upper die base and the lower die cutting edge is installed in the lower die base.

[0004] This document discloses a continuous stamping die that can complete the stamping of a workpiece with a single die. However, existing continuous stamping dies, such as those in this document, are fixed directly to the die or by a fixing device. Therefore, replacement is quite troublesome. Furthermore, if the workpieces in the same batch may have different dimensional requirements, it will take a lot of time to replace the stamping parts. Summary of the Invention

[0005] This utility model provides a shaping device for a navigation host mounting bracket, which can be changed according to the required bending angle of the workpiece, so that the bending angle of the workpiece can be guaranteed, and only the bending component needs to be replaced, without replacing the entire mold.

[0006] To achieve the above objectives, the present invention provides a shaping device for a navigation host mounting bracket. The shaping device is mounted on the lower die plate of a stamping mold and driven by the upper die plate. The shaping device includes a shaping mounting base, a shaping fixing block, and a shaping slider. The shaping mounting base is fixedly mounted on the lower die plate. A shaping fixing block is fixed on the lower die plate on one side of the shaping mounting base. The shaping slider is slidably positioned between the shaping mounting base and the shaping fixing block, forming a shaping interval between them. When the upper die plate moves downwards, it drives the shaping slider closer to the shaping fixing block, thereby shaping and bending the workpiece located within the shaping interval. A shaping inclined surface is provided on the side of the shaping slider near the shaping fixing block, tilting downwards and inwards from the top of the shaping slider. The tilt angle of the shaping inclined surface corresponds to the bending angle of the workpiece.

[0007] The above setup, through the inclusion of a shaping device, allows for a single shaping of the workpiece after bending, ensuring that the bending angle remains within acceptable tolerances and improving the quality of the final product. During bending and shaping, since the inclination angle of the shaping slider corresponds to the bending angle of the workpiece, the workpiece can be bent simply by driving the shaping slider downwards via the upper template. The structure is simple and reliable. Furthermore, when changing to workpieces of different sizes, the shaping slider can be easily replaced by simply removing it and replacing it with the one corresponding to the current workpiece. This ensures that the device can be easily changed according to the required bending angle of the workpiece.

[0008] Furthermore, a reset component is provided on the lower template below the shaping slider, which drives the shaping slider to move upward and reset.

[0009] The above settings allow the upper template to move upwards easily, and the resetting component enables the shaping slider to be reset more effectively.

[0010] Furthermore, the shaping mounting base extends downward and outward from the top of the shaping mounting base to form a guide slope on the side near the shaping fixing block. The shaping slider slides along the guide slope. When the upper template moves downward, it drives the shaping slider to slide along the guide slope, thereby approaching the shaping fixing block and shaping and bending the workpiece located in the shaping area.

[0011] The above setup, through the design of the guide ramp, ensures that the upper template can drive the shaping slider to move closer to the shaping fixing block, resulting in a simple and effective structure.

[0012] Furthermore, the reset assembly includes a reset pin and a reset spring. A reset pin hole is provided on the lower template below the shaping slider. One end of the reset spring is connected to the bottom of the reset pin hole, and a reset pin is provided on the other end of the reset spring. When the upper template moves the shaping slider downward, it pushes the reset pin to move and compresses the reset spring. When the upper template moves upward, the elastic force of the reset spring lifts the shaping slider up, thereby resetting the shaping slider.

[0013] The above settings, by setting a reset pin, enable the shaping slider to reset after shaping, thereby ensuring that it will not affect the next shaping.

[0014] Furthermore, a limiting groove is provided on the guide slope of the shaping mounting base, and a limiting block corresponding to the limiting groove is provided on the shaping slider. The limiting block is slidably positioned within the limiting groove.

[0015] The above settings, through the setting of the limiting groove, make it difficult for the shaping slider to detach from the shaping mounting base, thereby ensuring that misalignment will not occur during shaping.

[0016] Furthermore, the two sides of the limiting groove are inclined towards the center to form a dovetail groove, and the two sides of the limiting block are provided with dovetails corresponding to the dovetail groove.

[0017] The above settings, through the dovetail groove, ensure that the shaping slider is confined to the shaping mounting base and will not detach. This guarantees that the shaping slider is not directly connected to the shaping mounting base while restricting its movement along the guide slope, thus facilitating the replacement of the shaping slider.

[0018] Furthermore, the shaping and fixing block is pushed by the shaping push block. The end of the shaping push block near the shaping and fixing block is provided with a first inclined surface, and the shaping and fixing block is provided with a second inclined surface corresponding to the first inclined surface.

[0019] The above configuration, by setting a first inclined surface on the shaping and fixing block, allows the shaping pusher to easily move the shaping and fixing block.

[0020] Furthermore, a third inclined surface is provided on the upper end of the shaping fixing block near the shaping slider, a vertical surface is provided on the lower end of the shaping fixing block, a shaping inclined surface is provided on the side of the shaping slider near the third inclined surface, the inclination angles of the third inclined surface and the shaping inclined surface are matched, and a shaping interval is formed between the fourth inclined surface and the vertical surface.

[0021] The above settings allow the vertical surface to accommodate the product's bent edge, while the third inclined surface corresponds to the shaping inclined surface, enabling easy bending to form the second inclined edge.

[0022] Furthermore, a receiving cavity is provided on the lower mold, a groove is provided at the bottom of the receiving cavity, a sliding block is provided on the groove, an elastic element is provided at one end of the shaping push block near the upper mold inside the groove, one end of the elastic element is fixedly connected to the inner side wall of the groove, the other end of the elastic element is fixedly connected to one end of the sliding block, and a shaping fixing block is fixedly provided on the sliding block.

[0023] The above settings, through the inclusion of elastic elements and sliding grooves, allow the shaping and fixing block to slide within the grooves when pressed down. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1-4 As shown, a shaping device 4 for a navigation host mounting bracket is provided. The shaping device 4 is mounted on the lower template 2 of a stamping die and driven by the upper template (not shown). The shaping device 4 includes a shaping mounting base 41, a shaping fixing block 42, and a shaping slider 43. The shaping mounting base 41 is fixedly mounted on the lower template 2. The shaping fixing block 42 is fixed on one side of the lower template 2. The shaping slider 43 is slidably disposed between the shaping mounting base 41 and the shaping fixing block 42, forming a shaping area between the shaping fixing block 42 and the shaping slider 43. When the upper template moves downward, it drives the shaping slider 43 to approach the shaping fixing block 42, thereby shaping and bending the workpiece (not shown in the figure) located in the shaping interval 40. When the upper template moves upward, a reset component is provided on the lower template 2 below the shaping slider 43. The reset component drives the shaping slider 43 to move upward and reset. On the side of the shaping slider 43 near the shaping fixing block 42, there is a shaping inclined surface 432 that is inclined downward and inward from the top of the shaping slider 43. The inclination angle of the shaping inclined surface 432 corresponds to the bending angle of the workpiece (not shown in the figure).

[0031] In this embodiment, the end face of the shaping fixing block 42 is flush with the end face of the lower template 2; a workpiece limiting platform 45 is provided on the lower template 2 on the side of the shaping fixing block 42 away from the shaping mounting base 41, the bending surface of the workpiece is located within the shaping interval 40, and the other end of the workpiece is placed on the station limiting platform 45. This arrangement allows the workpiece to be restricted on the shaping device 4, thereby facilitating the shaping of the workpiece.

[0032] like Figure 5 As shown, the shaping mounting base 41 extends downward and outward from the top of the shaping mounting base 41 near the shaping fixing block 42 to form a guide slope 411. The shaping slider 43 is slidably disposed along the guide slope. When the upper template moves downward, it drives the shaping slider 43 to slide along the guide slope 411, thereby approaching the shaping fixing block 42 and shaping and bending the workpiece located in the shaping interval 40. The guide slope 411 ensures that the upper template can drive the shaping slider 43 to move towards the shaping fixing block 42, resulting in a simple and effective structure.

[0033] In this embodiment, when the upper template moves downward, the lower template contacts the shaping slider 43 and pushes the shaping slider 43 to slide downward along the guide slope 411 of the shaping mounting base 41, thereby driving the shaping slider 43 and the shaping fixing block 42 to cooperate with each other to shape the bending surface of the workpiece.

[0034] The reset assembly includes a reset pin 44 and a reset spring (not shown in the figure). A reset pin hole 401 is provided on the lower template 2 below the shaping slider 43. One end of the reset spring is connected to the bottom of the reset pin hole 401, and the other end of the reset spring is provided with the reset pin 44. When the upper template moves the shaping slider 43 downwards, it pushes the reset pin 44 to move and compresses the reset spring. When the upper template moves upwards, the elastic force of the reset spring lifts the shaping slider 43, thus resetting it. By setting the reset pin 44, the shaping slider 43 can be reset after shaping, thereby ensuring that it will not affect the next shaping operation.

[0035] A limiting groove 412 is provided on the guide slope 411 of the shaping mounting base 41, and a limiting block 431 corresponding to the limiting groove 412 is provided on the shaping slider 43. The limiting block 431 is slidably disposed within the limiting groove 412. The limiting groove 412 prevents the shaping slider 43 from easily disengaging from the shaping mounting base 41, thereby ensuring that misalignment does not occur during shaping.

[0036] like Figure 2As shown, the two sides of the limiting groove 412 are inclined towards the center to form dovetail grooves 413, and the two sides of the limiting block 431 are provided with dovetails 433 corresponding to the dovetail grooves 413. The dovetail grooves 413 ensure that the shaping slider 43 can be restricted on the shaping mounting base 41 and will not detach. This ensures that the shaping slider 43 is not directly connected to the shaping mounting base 41, while restricting the movement of the shaping slider 43 along the guide slope, thus facilitating the replacement of the shaping slider 43.

[0037] In this embodiment, as Figure 3 As shown, the lower mold 2 is provided with a receiving cavity 201, and the bottom of the receiving cavity 201 is provided with a sliding groove 202. A sliding block 203 is provided on the sliding groove 202. An elastic element (not shown in the figure) is provided at one end of the shaping push block 101 near the upper mold in the sliding groove. One end of the elastic element is fixedly connected to the inner sidewall of the sliding groove 202, and the other end of the elastic element is fixedly connected to one end of the sliding block 203. A shaping fixing block 42 is fixedly provided on the sliding block 203. In this embodiment, a fixing screw is provided on the sliding block 203 and fixedly connected to the shaping fixing block 42. The elastic element is a spring. When the upper mold is pressed down, the elastic element extends. When the upper mold moves up, the elastic element returns to its original shape, thereby causing the shaping fixing block 42 to reset to the corresponding position, so that the shaping fixing block 42 can slide in the sliding groove 202.

[0038] like Figure 4 As shown, the shaping push block 101 has a first inclined surface 1011 at one end near the shaping fixing block 42, the shaping fixing block 42 has a second inclined surface 421 corresponding to the first inclined surface 1011, the upper end of the shaping fixing block 42 near the shaping slider 43 has a third inclined surface 422, the lower end of the shaping fixing block 42 has a vertical surface, the shaping slider 43 has a shaping inclined surface 431 near the third inclined surface 422, the inclination angles of the third inclined surface 422 and the shaping inclined surface 431 are matched, and the fourth inclined surface 431 and the vertical surface form a shaping interval 40. The upper die moves downward, causing the shaping push block 101 to contact the second inclined surface 414 on the shaping fixing block 42, and the upper die to contact the top of the shaping slider 43. As the upper die continues to move downward, the shaping push block 101 causes the shaping fixing block 42 to move to one side of the shaping slider 43, and the shaping slider 43 moves downward. At the same time, the shaping inclined surface 431 on the shaping slider 43 contacts the third inclined surface 422, thereby allowing the workpiece between the shaping slider 43 and the shaping fixing block 42 to be further shaped.

[0039] like Figure 5As shown, the shaping device 4 can shape the pre-bent product. The final product includes a horizontal plate 01, a reinforcing rib 014, a first inclined edge 012, a second inclined edge 013, and a bent edge 0121. The shaping device 4 is used to shape the first inclined edge 012. The second inclined edge 012 is pre-bent first, and then the second inclined edge 012 is placed into the shaping interval 40 of the shaping device. Then, the upper die drives the shaping fixing block 41 to move towards the shaping slider 43. At the same time, the shaping slider 43 moves towards the lower die under the pressure of the upper die, thereby reducing the shaping interval 40 between the shaping fixing block 41 and the pre-shaping slider 43. The second inclined edge 012 is shaped between the third inclined surface 422 and the pre-shaping inclined surface 431. After the shaping is completed, the upper die or other pressing mechanism moves upward, and the shaping fixing block 41 returns to its original position under the action of the elastic element. The shaping slider 43 is reset under the action of the reset component.

[0040] The working principle of this utility model is as follows: By setting up a shaping device 4, after the workpiece is bent, the shaping device 4 shapes the workpiece once, so that the bending angle of the workpiece can be guaranteed to be within the allowable deviation range, thereby improving the quality of the final product. During bending and shaping, since the inclination angle of the shaping slope 432 of the shaping slider 43 corresponds to the bending angle of the workpiece, the shaping slider 43 can be bent simply by driving the upper template to move it down. The structure is simple and reliable. At the same time, when it is necessary to change to a workpiece of different sizes, it is only necessary to take out the shaping slider 43 and replace it with the shaping slider 43 corresponding to the current workpiece to realize the quick replacement of the shaping device 4. This ensures that it can be replaced according to the required bending angle of the workpiece, and the replacement is convenient, thereby making the bending efficiency higher.
