Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile part stamping, in particular to a stamping method and system for a top cover outer plate sky screen area of an automobile. BACKGROUND

[0002] The conventional stamping process for the sky screen area of the top cover outer plate part is mainly realized through processes such as drawing, local trimming, punching, trimming, cutting, flanging and shaping. The glass sky screen size of the part is large, the part hollow area is large, and the part formability is prone to be insufficient, which can cause local concave of the part, and the flange width of the sky screen area is large, generally about 25 mm, and the coplanar precision of the flange area is 0.3 mm, which is difficult to achieve.

[0003] In a current scheme for stamping the sky screen area of the top cover outer plate, the waste material in the middle sky screen area of the top cover outer plate part is separated from the part in two processes, and the middle flange area is shaped at the same time when the third process is completely separated. Since the shaping content starts first, the trimming edge starts trimming after the shaping of about 7 mm, so that the waste material is separated, and then the shaping is continued to the end. At the beginning of the shaping, the material flow-in condition of the unseparated waste material connection is different from that of the material of the trimming completed in the previous process, which can cause the material flow-in of the unseparated part to be blocked, and a part of the material is forced to flow in from the appearance side of the part product, causing the appearance of the ridge line of the sky screen area to be not smooth, and the coplanar precision of the flange of the sky screen area not to meet the quality requirements.

[0004] In another scheme, the middle skylight area of the top cover outer plate part is not compensated in shape, and the waste material in the middle is separated from the part in two processes, and the middle flange area is shaped at the same time when the third process is completely separated. Since the middle is not compensated, the part body is separated from the waste material first, and then the shaping is started, which ensures the consistency of the material flow-in of the entire flange area, but the sinking step drawing process of the skylight area is not compensated, and is completely realized by the shaping of the later process. The material flow-in amount of the part in the shaping process in this area is large, which can cause the appearance ridge line around the skylight to slide downward, causing the risk of local appearance defects, and the springback caused by the excessive material flow-in amount, which is easy to cause the quality of the part to be substandard

[0005] Therefore, the existing scheme is prone to cause the quality precision of the part to not meet the requirements in the implementation process, and needs to be improved. SUMMARY

[0042] In order to make the person skilled in the art better understand the scheme of the present application, the technical scheme in the embodiment of the present application will be described clearly and completely in combination with the drawings in the embodiment of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor are within the scope of protection of the present application.

[0043] The embodiment of the application provides a stamping method and system for a sunroof area of an automobile roof outer plate, which can solve the problem of poor quality precision of the sunroof area of the automobile roof outer plate caused by using the current stamping process.

[0044] The automobile roof sunroof is usually referred to as an automobile sunroof or a panoramic sunroof, is a large transparent glass installed on the roof of an automobile, and does not have an opening function, and therefore is often referred to as a fixed sunroof. Compared with an openable panoramic sunroof, the main characteristics of the sunroof lie in its fixity and light transmission. The sunroof cannot be opened through a key or the like, but can provide sufficient light and a field of view for the interior of the automobile. However, the central hollow area 2 of the sunroof area of the automobile roof outer plate can also be made into a sunroof. The difference between the sunroof and the sunroof lies in that the sunroof can be opened and closed, and the sunroof cannot be opened and is fully enclosed. However, whether it is the sunroof or the sunroof, the central part of the automobile roof outer plate needs to be cut to form the central hollow area 2, and then the glass is assembled. How to recycle the part of the material in the central hollow area 2 is required for the panoramic sunroof and the panoramic sunroof. Therefore, in the present application, the sunroof area of the automobile roof outer plate should be understood in a broad sense, that is, the sunroof area of the automobile roof outer plate 1 does not only refer to the sunroof, but excludes the sunroof, and should be understood as including the sunroof and the sunroof.

[0045] Referring to Figures 1 to 13 In a first aspect, the embodiment of the application provides a stamping method for a sunroof area of an automobile roof outer plate, which comprises the following steps.

[0046] 101: drawing forming is performed on the sunroof area of the automobile roof outer plate 1, and process compensation is performed on the central hollow area 2 of the sunroof area;

[0047] 102: the sunroof area is ring-cut and shaped, the automobile roof outer plate 1 is separated from the shaped waste material, and a consistent sunroof area trimming profile is obtained;

[0048] 103: the sunroof area is shaped to form a shaped material inflow space;

[0049] 104: the sunroof area is punched.

[0050] In the application, first, the canopy area of the top cover outer plate 1 is drawn and formed, and the hollow area 2 in the middle of the canopy area is process compensated, then the shape waste of the canopy area is ring cut and shaped, the top cover outer plate 1 is separated from the shape waste, and a consistent canopy area trimming profile is obtained, then the canopy area is shaped to form a shaped material inflow space, and finally the canopy area is punched. By process compensating the canopy area, the draw forming fullness of the product is increased; by ring cutting the shape waste of the canopy area, it is ensured that the part and the waste are completely separated and pulled apart by a certain distance to facilitate process transfer, and the consistency of the shaped material inflow in the subsequent process is also ensured, avoiding a series of quality defects caused by the untrimmed part in the traditional process when shaping the canopy area, which can improve the product precision and is beneficial to the transfer between part processes and the collection of tail waste, and the shape waste is shaped to shrink the shape waste peripheral profile edge line and reduce the circumference, avoiding the collision between the part and the shape waste due to the small gap between the waste ring cutting and the shape waste during the process transfer, causing appearance defects of the part; by shaping the canopy area, the quality precision of the product is further improved.

[0051] In step 101: the canopy area of the top cover outer plate 1 is drawn and formed, and the hollow area 2 in the middle of the canopy area is process compensated, the specific steps include step 1011 to step 1012:

[0052] Referring to Figure 2 The canopy area mainly includes two parts, which are divided into an installation area and a waste area. The installation area will form the installation position of the glass canopy through subsequent shaping, and the waste area forms the hollow area 2 on the top cover outer plate 1 part semi-finished product after cutting, and the cut material is recycled.

[0053] Step 1011: Pre-drawing the canopy area of the top cover outer plate 1.

[0054] First, the canopy area of the top cover outer plate 1 is pre-drawn to ensure the draw forming process, and the part made by the draw forming process has high dimensional accuracy and low surface roughness. In the draw forming process, part of the material is first flowed into the canopy area to avoid insufficient inflow of the shaping material in the subsequent process.

[0055] Step 1012: Hollow shape is set in the hollow area 2 in the middle of the canopy area, and process compensation is performed.

[0056] Before pre-drawing the canopy area, the hollow shape is designed in advance, so that the draw shape of the middle hollow area 2 is process compensated after pre-drawing the canopy area of the top cover outer plate 1, and the error caused by assembly or processing is partially offset or processed to achieve the required accuracy, which is convenient for draw forming fullness.

[0057] In the process of process compensation, the distance between the waste area of the awning area and the product unfolding line on the awning product area of the awning area is greater than or equal to the first design value. In this embodiment, the first design value is set to 10 mm. It should be noted that the first design value is not fixed and can be adjusted as needed in other embodiments. In this embodiment, the distance between the waste area of the awning area and the product unfolding line on the awning product area of the awning area is greater than or equal to 10 mm, which can ensure that the edge of the subsequent process has sufficient strength and avoid affecting the edge strength due to the shape of the compensation.

[0058] On the basis of the above-mentioned embodiments, in this embodiment, the shape waste of the awning area is ring-cut and shaped to separate the top cover outer plate 1 from the waste and obtain a consistent awning area trimming profile, specifically comprising steps 1020 to 1021:

[0059] Step 1020: Ring-cut the shape waste of the waste area of the awning area along the product unfolding line to obtain a consistent awning area trimming profile.

[0060] Specifically, referring to Figure 3 , the shape waste of the waste area is completely cut along the circumference of the glass awning area to form a consistent awning area trimming profile on the circumference of the awning area. The consistent awning area trimming profile here is that the flange face area of the awning area trimming profile has the same coplanarity, and the appearance edge line of the awning area has the same round corner. Since the shape waste of the waste area is completely cut, the shape waste is also complete, which is convenient for subsequent collection. Among them Figure 3 , X1 represents the ring-cut line, and X2 is the shaped shape waste boundary line.

[0061] Step 1021: Shape the shape waste to separate the awning area of the top cover outer plate 1 from the shape waste.

[0062] After step 1020 is completed, the shape waste and the awning area are not completely separated, so the shape waste needs to be shaped. Referring to Figure 5 and Figure 6 , the dashed line in Figure 5 and Figure 6 is the shape of the shape waste after ring-cutting without waste before shaping the shape waste. The distance between the top cover outer plate 1 part and the shape waste is zero. If the shape waste is not shaped, it is easy to cause the part profile of the awning area to be deformed by knocking during process transfer; after the shape waste is shaped, the shape waste profile is contracted and reduced, and the top cover outer plate 1 part is pulled away from the shape waste by a certain distance, avoiding the top cover outer plate 1 part from being knocked during process transfer, and ensuring the quality of the top cover outer plate 1 part.

[0063] In the embodiment, when the shape scrap is reshaped, the reshaping shrinkage of the shape scrap is greater than or equal to the second design value. The second design value is set to 5 mm, which ensures that there is sufficient safety allowance during the process transfer to avoid the problem of appearance quality caused by the collision between the top cover outer plate 1 part and the shape scrap.

[0064] On the basis of the above embodiment, in the embodiment, in step 103, the sky region is reshaped to form a reshaping material inflow space, in particular:

[0065] Since the shape scrap has been completely separated from the sky region in step 102, the sky region is trimmed to have a consistent trimming profile by trimming the shape scrap, as shown in Figures 7 to 11 When the sky region is reshaped in this process, the consistent reshaping material inflow condition is obtained from the complete trimming profile to form a consistent reshaping material inflow space. The material inflow space is a key element in the reshaping process of the automobile top cover, which directly affects the forming quality and production efficiency of the top cover. The consistent material inflow space can ensure that the process parameters of the top cover outer plate 1 are consistent during the drawing process, which can optimize the forming quality and production efficiency of the top cover outer plate 1. The inconsistent reshaping material inflow phenomenon caused by the simultaneous trimming and edge trimming of the traditional process in this process part position avoids the out-of-tolerance problem of the flange surface area of the sky region and the appearance of the sky region. At the same time, by reshaping the sky region, the distance between the top cover outer plate 1 and the shape scrap is further increased.

[0066] In Figure 8 , X4 is the complete and consistent trimming profile of the sky region, and X3 is the trimming profile edge line of the sky region after reshaping. In Figure 10 and Figure 11 , Y1 represents the pre-drawing shape of the sky region, and Y2 represents the shape of the sky region after reshaping, which can be directly observed that the appearance of the sky region is adjusted during reshaping.

[0067] On the basis of the above embodiment, in the embodiment, in step 104, the sky region is punched, in particular:

[0068] The positioning hole is punched on the intermediate sky installation table. When the sky region is punched, the shape scrap is moved along the vehicle coordinate system Z direction by the transfer end picker between the third process and the fourth process to separate the automobile top cover outer plate 1 from the shape scrap. In the embodiment, the Z direction height position of the shape scrap of the sky region is adjusted downward by a set value along the vehicle coordinate system Z direction, which can be 15 mm in the embodiment, to separate the automobile top cover outer plate 1 from the shape scrap, as shown in Figure 13 Figure 13 ​Z1 is the Z-direction height position of the shape scrap before adjustment, and Z2 is the Z-direction height position of the shape scrap after adjustment. When the tail-end robot transfers the automobile roof outer plate 1 and the shape scrap to the belt conveyor, the shape scrap is ensured to fall on the belt conveyor first, and the automobile roof outer plate 1 falls on the belt conveyor later, so that the automobile roof outer plate 1 and the shape scrap are managed in layers, and collision between the automobile roof outer plate 1 and the shape scrap is avoided, and the automobile roof outer plate 1 and the shape scrap can be better collected respectively.

[0069] It should be noted that after the shape of the sky region is adjusted to form a shape scrap, the Z-direction height position of the shape scrap in the sky region area can be first adjusted downward by a set value, and the shape scrap and the automobile roof outer plate 1 are transferred separately in step 104. Since the process in step 104 is simple, the Z-direction height position of the shape scrap in the sky region area is adjusted downward by a set value when the sky region is punched as preferred.

[0070] In summary, in the process, through the ingenious process design of the roof outer plate 1 part, the consistency of the material flow into the sky region of the roof outer plate 1 is ensured, the quality precision of the roof outer plate 1 is ensured, and the excess available scrap of the intermediate sky region is obtained. Specifically, the first process increases the shape process compensation in the sky region to increase the draw forming fullness of the part, the second process circles and shapes the shape scrap in the scrap area, ensures that the roof outer plate 1 and the shape scrap are separated and pulled apart by a certain distance for process transfer, and facilitates the third process to shape the sky region to ensure the consistency of the material flow into the sky region; in the third process, the sky region is shaped to achieve the required part quality precision; in the fourth process, through process transfer and structural design, the shape scrap in the sky region is lowered by 15mm, the shape scrap and the roof outer plate 1 are managed in layers when the part tail, and the part is prevented from being knocked around. Through the reasonable arrangement of a series of process contents, good flange surface coplanar precision of the sky region and available scrap tail collection are obtained. In addition, the intermediate shape scrap in the trimming process is circled to separate the scrap from the sky region, an open material flow into the trimming profile of the sky region is obtained, the consistency of the material flow into the sky region is ensured, and a series of quality defects caused by the untrimmed part in the traditional process are avoided; and the shape scrap is shaped around, so that the shape scrap contour line is contracted, the circumference is reduced, and collision between the roof outer plate 1 and the shape scrap caused by the small gap between the untrimmed scrap and the shape scrap during process transfer is avoided, and appearance defects of the part are caused.

[0071] In a second aspect, the embodiments of the present application provide a stamping system for a roof outer panel sky region, comprising: a first module, a second module, a third module and a fourth module, the first module is used for drawing forming the sky region of the roof outer panel 1, and process compensation is performed on the hollow region 2 in the middle of the sky region; the second module is used for ring cutting and shaping the shape waste of the sky region, separating the roof outer panel 1 from the waste, and obtaining a consistent sky region trimming profile; the third module is used for shaping the sky region to form a shaped material inflow space; and the fourth module is used for punching the sky region.

[0072] In the present application, the process compensation is performed on the sky region to increase the drawing forming sufficiency of the product; the shape waste of the sky region is ring cut to ensure that the part and the waste are completely separated and pulled apart by a certain distance for convenient process transfer, and also to ensure the consistency of the shaped material inflow in the subsequent process, avoid a series of quality defects caused by the untrimmed part in the sky region shaping in the traditional process, improve the product precision, facilitate the transfer between part processes and the collection of tail waste, shape the shape waste to shrink the waste peripheral profile edge line, reduce the circumference, avoid the collision between the part and the shape waste in the process transfer process due to the small gap between the waste ring cutting and the shape waste, and cause the appearance defects of the part; the sky region is shaped to further improve the quality precision of the product.
