Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production, in particular to a shaping device and a mold. Background Art

[0002] The tail structure of the car's roof panel is deep and usually concave, which makes it have a negative angle in the vertical stamping direction of the mold and cannot be directly stamped. Therefore, in the production process of the tail structure of the current car roof panel, it is generally first drawn out of the approximate shape through a stamping process with a vertical downward stamping direction to prefabricate a drawn part. This drawn part includes a top large surface, a drawn tail drawn side surface, and a drawn fillet that transitions between the top large surface and the tail drawn side surface, wherein the tail drawn side surface has no negative angle in the stamping direction.

[0003] After the drawn part is processed, the side shaping process is then used to shape the drawn part into place, so as to shape the tail drawn side surface into a product tail side surface with a negative angle in the vertical stamping direction, and also shape the drawn fillet into the final product fillet. In the above-mentioned existing side shaping process, the drawn part is shaped to the final product profile by moving downward at an angle of 40°-50° to the vertical stamping direction. The inclined wedge will generate a horizontal component force during the movement in the inclined direction, which often causes quality problems such as the product fillet arching upward, uneven size, and unevenness. Utility Model Content

[0004] The utility model aims to improve the quality of the rounded corner of the rear end of the outer plate of the roof cover.

[0005] In order to solve the above problems, the utility model provides a shaping device for shaping a roof cover outer panel drawn part, the roof cover outer panel drawn part includes a tail drawn side and a drawn fillet, the shaping device includes a positive shaping insert and a side shaping insert, the positive shaping insert is used to act on the drawing fillet along the vertical direction to shape the drawing fillet into a product fillet, the side shaping insert is used to move along a set inclined direction and act on the tail drawn side to shape the tail drawn side into a product tail side.

[0006] Compared with the prior art, the plastic surgery device provided by the utility model has but is not limited to the following technical effects:

[0007] When producing the outer panel of the vehicle roof cover, the drawn part of the vehicle roof cover outer panel can be processed first as in the prior art, and the drawn part of the vehicle roof cover outer panel also includes a top large surface, a rear drawn side surface, and a drawn fillet that transitionally connects the two. The difference from the prior art is that when shaping the drawn part of the vehicle roof cover outer panel, the shaping device provided by the utility model can first be used to move the positive shaping insert vertically and act on the drawn fillet to shape the drawn fillet into the required product fillet. During the process of the positive shaping insert acting on the drawing fillet or after the positive shaping insert acts to form the product fillet, its front side surface is vertically attached to the product fillet. At this time, the side shaping insert can be moved along the set inclined direction and act on the rear drawn side surface to make the rear drawn side surface concave and then shaped into the required product rear side surface, and at the same time, the product rear side surface is transitionally connected to the top large surface through the product fillet. Since the positive shaping insert moves along the vertical stamping direction when the roof cover outer panel is formed, no horizontal force component is generated, so the product fillet will not cause quality defects such as upward arching and unevenness. Compared with the product fillet directly formed by moving downward at an oblique angle of 40°-50° with the vertical stamping direction, this embodiment can ensure the quality of fillet forming. Moreover, in the process of the side shaping insert performing side shaping on the tail drawn side along the oblique direction, the front side of the positive shaping insert can be close to and press the product fillet that has been processed or is being processed, which plays a protective role in the quality of the product fillet, and ensures that the product fillet is not easy to deform (for example, upward arching) when the side shaping insert is side shaping. In addition, when the product fillet is processed and formed one step ahead of the product tail side, the product fillet at this time will produce greater work hardening due to plastic deformation, making it less likely to be deformed by the oblique movement of the side shaping insert, which can further avoid the deformation of the product fillet caused by the side shaping of the side shaping insert, thereby further ensuring the quality of the product fillet.

[0008] Furthermore, an inclined surface is provided on the rear side of the positive shaping insert, the bottom end of the inclined surface is located in front and below the top end of the inclined surface, and the bottom end of the inclined surface is the lowest point of the positive shaping insert.

[0009] Furthermore, the shaping device also includes a positioning mechanism, and the positioning mechanism is used to fix the drawn part of the roof cover outer panel.

[0010] The utility model also provides a mold, comprising the shaping device as mentioned above.

[0011] Since the technical improvement and technical effect of the mold are the same as those of the shaping device, the mold will not be described in detail.

[0012] Furthermore, the mold also includes an upper mold base, and the positive shaping insert of the shaping device is installed on the upper mold base, and the positive shaping insert is used to move vertically with the upper mold base.

[0013] Furthermore, the mold also includes a lower mold base and an inclined wedge seat, the upper mold base is provided with a first guide device, and the lower mold base is provided with a second guide device, the guiding direction of the second guide device is parallel to the set inclination direction, and the distance between the second guide device and the first guide device increases from the back to the front direction, the side shaping insert of the shaping device is installed on the inclined wedge seat, the inclined wedge seat is slidably connected to the first guide device, and the inclined wedge seat is used to move along the guiding direction of the second guide device.

[0014] Furthermore, a front end height of the first guide device is higher than or equal to a rear end height.

[0015] Furthermore, the positioning mechanism of the shaping device includes a pressing plate and a telescopic member, one end of the telescopic member is connected to the upper die base, and the other end of the telescopic member is connected to the pressing plate, and the pressing plate is used to press on the top large surface of the drawn part of the roof cover outer panel.

[0016] Further, the telescopic member is an elastic member with vertical telescopic capability, or the telescopic member is a nitrogen cylinder.

[0017] Furthermore, the pressing plate is arranged close to the side wall of the positive shaping insert and in a gap with the positive shaping insert. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] It should also be noted that the aforementioned X-axis and Z-axis are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] See also Figure 1-4 A shaping device according to an embodiment of the utility model is used to shape a roof cover outer panel drawn part 1, wherein the roof cover outer panel drawn part 1 includes a rear drawn side surface 12 and a drawn fillet 13, and the shaping device includes a positive shaping insert 2 and a side shaping insert 3. The positive shaping insert 2 is used to act on the drawn fillet 13 along the vertical direction to shape the drawn fillet 13 into a product fillet 14, and the side shaping insert 3 is used to move along a set inclined direction and act on the rear drawn side surface 12 to shape the rear drawn side surface 12 into a product rear side surface 15.

[0029] In this embodiment, when producing the roof cover outer panel, the roof cover outer panel drawn part 1 can be first processed in the same way as in the prior art. The roof cover outer panel drawn part 1 also includes a top large surface 11, a rear drawn side surface 12 and a drawn fillet 13 transitionally connecting the two. The difference from the prior art is that, when shaping the roof cover outer panel drawn part 1, the shaping device provided by the utility model can be used to first move the positive shaping insert 2 vertically and act on the drawing fillet 13 to shape the drawing fillet 13 into the required product fillet 14. During the process of the positive shaping insert 2 acting on the drawing fillet 13 or after the product fillet 14 is formed, its front side surface is vertically abutted against the product fillet 14. At this time, the side shaping insert 3 can be moved along the set inclined direction and act on the rear drawing side surface 12 to make the rear drawing side surface 12 concave and then shaped into the required product rear side surface 15, while realizing the transition connection between the product rear side surface 15 and the top large surface 11 through the product fillet 14.

[0030] It should be noted that the front side and the rear side of the roof cover outer panel drawn part 1 refer to the side facing the front of the vehicle and the side facing the rear of the vehicle when the roof cover outer panel drawn part 1 is applied to the vehicle body; in this embodiment, the front side (front end) and the rear side (front end) of the shaping device or each part structure in the mold refer to the side that corresponds to the front side and the rear side of the roof cover outer panel drawn part 1 respectively when the roof cover outer panel drawn part 1 is processed. For example, when the shaping device is used for processing the roof cover outer panel drawn part 1, the front side of its positive shaping insert 2 and the front side of the roof cover outer panel drawn part 1 are both facing the same side, and the rear side of its positive shaping insert 2 and the rear side of the roof cover outer panel drawn part 1 are both facing the same side.

[0031] In this embodiment, since the positive shaping insert 2 moves along the vertical stamping direction when the roof cover outer panel drawn part 1 is formed, no horizontal force component will be generated, so the product fillet 14 will not cause quality defects such as upward arching and irregularity. Compared with the product fillet 14 that is directly formed by moving downward at an angle of 40°-50° to the vertical stamping direction, this embodiment can ensure the quality of fillet forming. Moreover, in the process of the side shaping insert 3 shaping the tail drawn side surface 12 along the oblique direction, the front side surface of the positive shaping insert 2 can be close to and press the product fillet 14 that has been processed or is being processed, which protects the quality of the product fillet 14 and ensures that the product fillet 14 is not easily deformed (for example, arched upward) when the side shaping insert 3 is shaping the side. In addition, when the product fillet 14 is processed and formed ahead of the product tail side 15, the product fillet 14 at this time will produce greater work hardening due to plastic deformation, making it less likely to be deformed by the oblique movement of the side shaping insert 3, and can further avoid deformation of the product fillet 14 caused by side shaping of the side shaping insert 3, thereby further ensuring the quality of the product fillet 14.

[0032] Alternatively, see Figure 1 and 3 An inclined surface 21 is provided on the rear side of the positive shaping insert 2 , and the bottom end of the inclined surface 21 is located in front and below the top end of the inclined surface 21 , and the bottom end of the inclined surface 21 is the lowest point of the positive shaping insert 2 .

[0033] In this embodiment, an inclined surface 21 is provided on the rear side of the positive shaping insert 2, and the bottom end of the inclined surface 21 is located at the lowest point of the positive shaping insert 2, which is equivalent to cutting off a part of the rear side of the positive shaping insert 2 in an inclined direction to form the inclined surface 21. In this way, the side shaping insert 3 can be avoided. That is, when the side shaping insert 3 acts on the tail drawing side surface 12 from the rear side, the setting of the inclined surface 21 can ensure that the positive shaping insert 2 will not hinder or interfere with the movement of the side shaping insert 3.

[0034] Optionally, the shaping device further comprises a positioning mechanism, and the positioning mechanism is used to fix the roof cover outer panel drawn part 1.

[0035] In this embodiment, before the drawn roof cover outer panel part 1 is shaped, the drawn roof cover outer panel part 1 can be fixed by a positioning mechanism to prevent the drawn roof cover outer panel part 1 from moving during shaping, especially to prevent movement during side shaping of the side shaping insert 3.

[0036] Another embodiment of the utility model provides a mold, comprising the shaping device as described above.

[0037] Since the technical improvement and technical effect of the mold are the same as those of the shaping device, the mold will not be described in detail.

[0038] Alternatively, see Figure 1 and Figure 3 The mold also includes an upper mold base 4, and the positive shaping insert 2 of the shaping device is installed on the upper mold base 4, and the positive shaping insert 2 is used to move vertically with the upper mold base 4.

[0039] In this embodiment, the positive shaping insert 2 is installed on the upper die base 4 , and the positive shaping insert 2 can move with the vertical movement of the upper die base 4 to achieve the shaping of the drawn fillet 13 into the product fillet 14 .

[0040] It should be noted that the power source for the vertical movement of the upper die base 4 can come from a press commonly used in the die field.

[0041] Alternatively, see Figure 1 and Figure 3The mold also includes a lower mold base 5 and an inclined wedge seat 6. A first guide device 7 is provided on the upper mold base 4, and a second guide device 8 is provided on the lower mold base 5. The guiding direction of the second guide device 8 is parallel to the set tilting direction. In the direction from back to front, the distance between the second guide device 8 and the first guide device 7 increases gradually. The side shaping insert 3 of the shaping device is installed on the inclined wedge seat 6. The inclined wedge seat 6 is slidably connected to the first guide device 7, and the inclined wedge seat 6 is used to move along the guiding direction of the second guide device 8.

[0042] In this embodiment, the lower die seat 5 can be used to place the roof cover outer panel drawn part 1, that is, the roof cover outer panel drawn part 1 can be placed on the lower die seat 5, and then it can be positioned by the aforementioned positioning mechanism, and then subsequent shaping can be carried out.

[0043] In this embodiment, a first guide device 7 is also installed on the upper mold base 4. The first guide device 7 extends along the front-to-back direction and can be tilted at a small angle. The side shaping insert 3 is slidably fitted on the first guide device 7 through the inclined wedge seat 6, that is, the inclined wedge seat 6 is relatively fixed to the side shaping insert 3, the inclined wedge seat 6 can move along the first guide device 7, and the inclined wedge seat 6 always maintains a sliding connection relationship with the first guide device 7, that is, the inclined wedge seat 6 will not fall off the first guide device 7; at the same time, a second guide device 8 is also provided on the lower mold base 5, and the guiding direction of the second guide device 8 is parallel to the set tilting direction, that is, it extends obliquely downward in the direction from back to front, and the distance between the second guide device 8 and the first guide device 7 increases from back to front, and the inclined wedge seat 6 and the side shaping insert 3 can be arranged between the first guide device 7 and the second guide device 8.

[0044] In this way, through the setting of the above structure, after the positioning mechanism positions and fixes the roof cover outer panel drawn part 1, as the upper die seat 4 moves downward, the positive shaping insert 2 gradually moves downward and approaches the drawing radius 13, and at the same time, the inclined wedge seat 6 and the side shaping insert 3 also gradually move downward. When the positive shaping insert 2 just contacts the drawing fillet 13, the side shaping insert 3 can be in a state of just contacting the tail drawing side 12, and the inclined wedge seat 6 is in a state of just contacting the second guide device 8; as the upper die seat 4 continues to move downward, the positive shaping insert 2 continues to move downward and shapes the drawing fillet 13 into a product fillet 14 (for example, the fillet radius is 1-2mm). During the process of the positive shaping insert 2 shaping the drawing fillet 13, the inclined wedge seat 6 slidingly fitted on the first guide device 7 also contacts the second guide device 8 and begins to move obliquely downward along the second guide device 8, so that the side shaping insert 3 also begins to shape the tail drawing side 12 until it is shaped into the final product tail side 15, and the mold is closed (or mold closing). In this process, since the positive shaping insert 2 presses the product fillet 14 to play a protective role, the product fillet 14 is not easy to deform during the side shaping, ensuring the quality of the appearance fillet.

[0045] During the shaping process, the positive shaping insert 2 parallel to the stamping direction can exceed the product fillet 14 by a distance of L1 (L1 is 1mm-2mm) when the mold is closed to ensure that the product fillet 14 is completely processed, and the safety distance with the side shaping insert 3 is L2 (L2 is 0.5mm-1mm) to ensure that the mold does not interfere with each other. Moreover, since the positive shaping insert 2 will continue to exceed 1mm-2mm downward after processing the product fillet 14, the movement of the positive shaping insert 2 in this process can ensure that the side shaping insert 3 has enough oblique movement stroke to process the side surface 15 of the product tail in place; at the same time, in the process of the positive shaping insert 2 exceeding the product fillet 14 downward, the product fillet 14 has been completely formed and hardened in advance, and is not easy to be deformed due to the side shaping that has not been completely completed, and the positive shaping insert 2 cooperates with the protective effect of the product fillet 14 at this time to ensure that the side shaping movement that has not been completed will not cause the product fillet 14 to deform.

[0046] In this embodiment, the movement of the front shaping insert 2 and the movement of the side shaping insert 3 are both driven by the upper die base 4. Since they are completed in the same die, the use of one die is reduced, saving die development costs.

[0047] See also Figure 1 Specifically, the front end height of the first guide device 7 is higher than or equal to the rear end height.

[0048] In this embodiment, the front end height of the first guide device 7 is higher than or equal to the rear end height, ensuring that when the upper mold base 4 rises to the highest position after mold opening, the inclined wedge seat 6 is at the initial position of the rear end of the first guide device 7 under its own weight, and before the mold closing movement and the inclined wedge seat 6 does not contact the second guide device 8, the inclined wedge seat 6 will not move forward under its own weight (ensuring that the side shaping insert 3 has a subsequent moving stroke for side shaping); the inclined wedge seat 6 can only move downward along the second guide device 8 toward the front side under the guidance of the second guide device 8 after the upper mold base 4 moves downward and contacts the second guide device 8, so that the side shaping insert 3 can be side shaped. Among them, the front end height of the second guide device 8 is lower than the rear end height, so as to ensure that the inclined wedge seat 6 and the side shaping insert 3 can move in the oblique downward direction, and also ensure that there is no negative stamping angle when the side shaping insert 3 is side shaped in this direction.

[0049] Specifically, the inclined wedge seat 6 is respectively provided with a first guide matching structure and a second guide matching structure, the first guide matching structure is slidably matched with the first guide device 7, and the second guide matching structure is used to contact with the second guide device 8 and move along the guide direction of the second guide device 8.

[0050] See also Figure 1 Optionally, the positioning mechanism of the shaping device includes a pressing plate 9 and a telescopic member 10, one end of the telescopic member 10 is connected to the upper die base 4, and the other end of the telescopic member 10 is connected to the pressing plate 9, and the pressing plate 9 is used to press on the top large surface 11 of the roof cover outer panel drawn part 1.

[0051] In this embodiment, after the mold is opened (or called after the mold is opened), the telescopic part 10 can be extended to allow the pressing plate 9 to move downward to press and fix the top large surface 11. When the mold is closed, the upper mold base 4 gradually compresses the telescopic part 10 to ensure the closing of the mold.

[0052] Optionally, the telescopic member 10 is an elastic member with vertical telescopic capability, or the telescopic member 10 is a nitrogen cylinder.

[0053] The telescopic part 10 can be an elastic part. After the mold is opened, the pressing plate 9 can be lifted up and the elastic part can be compressed. Then the roof cover outer panel drawing part 1 can be placed on the lower mold base 5, and then the pressing plate 9 can be released. Then the pressing plate 9 presses the top large surface 11 under the action of the elastic part. When the mold is closed, the elastic part is compressed to ensure the closing of the mold. The telescopic part 10 can also be a nitrogen cylinder. After the mold is opened, the signal to the nitrogen cylinder is disconnected, the valve is opened, and the nitrogen cylinder starts to return to drive the pressing plate 9 to move downward to compress and fix the top large surface 11. When the mold is closed, a signal is given to the nitrogen cylinder to close the valve, and the nitrogen cylinder is controlled to be only compressed but not rebounded, so as to ensure that the nitrogen cylinder is gradually compressed to ensure the normal closing of the mold.

[0054] The top large surface 11 of the drawn roof panel 1 is pressed by the pressing plate 9 to ensure that all positions of the drawn roof panel 1 are positioned, thereby preventing the drawn roof panel 1 from molecular movement and affecting the shaping accuracy.

[0055] Optionally, the pressing plate 9 is arranged close to the side wall of the positive shaping insert 2 and in a gap with the positive shaping insert 2 .

[0056] In this embodiment, a gap is set between the rear side wall of the pressure plate 9 and the front side wall of the positive shaping insert 2 to ensure that there is no contact between the two, thereby facilitating the debugging of the mold and preventing the pressure plate 9 and the positive shaping insert 2 from interfering with each other during movement.

[0057] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0058] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
