Abstract
Description
Technical Field
[0001] This application relates to the technical field of automobile manufacturing, specifically to a blanking die stock support, and further to a blanking die including the stock support. Background Art
[0002] The stock support of a conventional blanking die has a brush or roller structure. The steel side wall single plate of a vehicle is relatively heavy, for example, more than 40 catties. After the trimming stop edge and the front and rear door openings are cut off, the center of gravity position will show a downward collapse trend. During the blanking process, as the sheet metal is transmitted at high speed along the feeding direction, the collapsed trimming stop edge and the guiding roller of the stock support have an alternating cutting movement, resulting in frequent cutting wear of the guiding roller. Due to the oil film on the sheet metal itself, a part of the cut-off roller debris is carried out with the high-speed transmitted sheet metal and remains on the side wall or surface of the sheet metal, affecting the stamping production efficiency.

[0027] Figure 1 FIG. shows a schematic diagram of a blank holder 1 of a blanking die according to an embodiment of the present application, in which the outline of a vehicle panel 2 (such as a vehicle side panel) is also schematically shown. The blank holder 1 is used to transport raw materials of the vehicle panel for manufacturing the vehicle panel 2 on the blanking die. The blank holder 1 includes a plurality of blank holding rollers 10 extending along the transportation direction of the raw materials of the vehicle panel on the blanking die (such as Figure 1 the direction from left to right in the figure). The raw materials of the vehicle panel are placed on the blank holder 1 and move along the transportation direction as the rollers rotate. It should be understood that Figure 1 FIG. shows a plurality of tracks arranged in parallel and extending horizontally, but each blank holding roller is not labeled for the purpose of clarity.
[0028] Referring to Figure 2 the schematic diagram of a blank holding roller 10 shown, it can be seen that the blank holding roller 10 includes a roller body 11 and an introduction end 12 located upstream of the roller body 11 along the transportation direction. The introduction end 12 is configured to be inclined downward from the roller body 11. A number of blank holding rollers 110 and a number of introduction rollers 120 made of metal (such as copper) are provided on the blank holding roller 10. The number of introduction rollers 120 are arranged in sequence from the introduction end 12 to the roller body 11 along the extension direction of the blank holding roller 10. A number of blank holding rollers 110 are arranged in sequence to connect to the introduction rollers 120 on the roller body 11. The blank holding rollers 110 can be made of polyurethane material, for example, to reduce manufacturing costs.
[0029] In such an arrangement, the stock support 1 described in this article effectively adapts to the situation of the edge collapse of the vehicle panel raw material caused by gravity during transportation (including the collapse of the edge of the original sheet raw material contour, the collapse of the edge of the cut contour, and / or the collapse of the edge of the internal styling notch) by setting the upstream end of the stock roller track 10 as a downwardly inclined inlet end 12, which plays a good guiding role. Moreover, it effectively weakens the impact and cutting effect of the edge of the vehicle panel raw material on the inlet roller 120, ensures the good appearance quality of the edge of the vehicle panel, reduces the damage rate of the inlet roller 120, and extends its service life. In addition, the inlet roller 120 is made of metal, which improves the stiffness and hardness of the inlet roller 120, avoids the roller slag falling caused by the cutting of the vehicle panel raw material on the inlet roller 120, so that the formed vehicle panel will not adhere to the roller debris, ensures the cleanliness of the vehicle panel raw material, saves the subsequent cleaning steps, and improves the production efficiency of the vehicle panel; at the same time, the stock support 1 will not accumulate roller debris, ensuring the cleanliness of the stock support 1 and improving the service life of the stock support 1.
[0030] The following will introduce the further specific implementation, refinement or improvement process of the stock support through exemplary explanations, so as to further improve its working efficiency, reliability or for other improvement considerations.
[0031] In one implementation, the end of the inlet end 12 is located 5 mm to 15 mm below the track main body 11. Alternatively, the inlet end 12 can be configured to be inclined downward 5 degrees to 30 degrees from the track main body 11.
[0032] In a further implementation, at least one of the plurality of inlet rollers 120 is provided on the inlet end 12, and at least one of the plurality of inlet rollers 120 is provided on the track main body 11. By partially extending the arrangement range of the inlet rollers 120 to the track main body 11, the cutting effect of the vehicle panel raw material on the rollers in the transition area between the inlet end 12 and the track main body 11 is further weakened, and the problem of roller slag falling is reduced. In a specific implementation, one of the plurality of inlet rollers 120 can be provided on the track main body 11, and the remaining inlet rollers 120 of the plurality of inlet rollers 120 are provided on the inlet end 12, so as to control the cost of setting the inlet rollers 120. For example Figure 2 As shown in, three inlet rollers 120 are provided on a stock roller track 10, one of the inlet rollers 120 is provided on the track main body 11, and the other two inlet rollers 120 are provided on the inlet end 12. In other implementations, the number and distribution of the inlet rollers 120 can also be determined according to actual requirements.
[0033] In a preferred implementation, as Figure 3 andFigure 4 As shown, the edge of the guiding roller 120 can be configured as a rounding structure 121, which can include an arc-shaped rounding structure, an elliptical arc-shaped rounding structure, or other structures with a smooth curved surface. The rounding structures 121 at the two edges of the guiding roller 120 can be designed as a symmetric structure as shown in Figure 3 or an asymmetric structure as shown in Figure 4 (that is, the rounding degree at one edge is larger and the rounding degree at the other edge is smaller, which will be further described in detail below in combination with the following description). In a preferred embodiment, a similar rounding structure can also be provided for the material supporting roller 110 to achieve smooth contact between the edge of the material supporting roller 110 and the vehicle body panel stock.
[0034] Return to reference Figure 1 , multiple areas of the material supporting frame 1 and the distribution of the material supporting raceways 10 in the material supporting frame 1 can be seen. At the same time, in combination with its distribution, the specific structure of the rounding structure 121 of the guiding roller 120 can be further described. As shown in Figure 1 , the material supporting frame 1 includes a feeding area 101 located upstream in the transportation direction and a discharging area 102 located downstream. The first set of the material supporting raceways 10 among the multiple material supporting raceways 10 are arranged in parallel in the feeding area 101, and the second set of the material supporting raceways 10 among the multiple material supporting raceways 10 are arranged in parallel in the discharging area 102. And the material supporting frame 1 further includes one or more tool edge-entry areas 103, and the tool edge-entry areas 103 are configured to match the shape of the area to be cut of the vehicle body panel stock. The area to be cut can include the area to be cut at the outer contour of the vehicle body panel stock, and after cutting, the outer contour of the vehicle body panel 2 can be formed, or it can also include the area to be cut inside the vehicle body panel stock, and after cutting, a styling notch inside the vehicle body panel 2 can be formed, such as a door opening inside the side panel. The third set of the material supporting raceways 10 among the multiple material supporting raceways 10 are arranged in parallel along the downstream edge (the edge located downstream in the transportation direction) of the tool edge-entry area 103 and extend downstream of the tool edge-entry area 103. It should be understood that the division of the areas in the figure is only schematic, and different area division situations can exist according to the specific shape of the vehicle body panel and the specific arrangement of the material supporting frame. Figure 5 is a schematic view of the tool edge-entry area 103 of the material supporting frame 1, in which the left structure is a schematic view of the blanking knife block 3 of the blanking die. The vehicle body panel stock is blanked at the blanking knife block to cut off the area to be cut, and then moves downstream and is guided onto the material supporting raceway 10 by the guiding roller 120 of the material supporting raceway 10.
[0035] Figure 1The positions of the leading ends 12 of the respective stock supporting raceways 10 are marked by circles. In the feeding area 101, when the edge of the vehicle body panel stock contacts the leading rollers 120, it is perpendicular to the transportation direction, that is, the edge of the vehicle body panel stock slides across the surface of the leading rollers 120 parallel to the axis of the leading rollers 120. In this case, the edges on both sides of the leading rollers 120 can be provided with rounded structures of the same size. In the tool entry area 103, for example Figure 1 in the first tool entry area 1031, the second tool entry area 1032, the third tool entry area 1033, the fourth tool entry area 1034, and the fifth tool entry area 1035 shown in, when the edge of the vehicle body panel stock contacts the leading rollers 120, the angle between it and the transportation direction is not 90 degrees, that is, the edge of the vehicle body panel stock is not parallel to the axis of the leading rollers 120. During transportation, the edge of the vehicle body panel stock contacts the first edge of the leading rollers 120 earlier and cuts more of the first edge 1201 of the leading rollers 120 (that is, the edge on the side where the edge of the vehicle body panel stock forms an acute angle with the transportation direction), and contacts the second edge 1202 axially opposite to the first edge later and less (that is, the edge on the side where the edge of the vehicle body panel stock forms an obtuse angle with the transportation direction). In this case, referring to Figure 4 , the degree of rounding of the rounding structure 121 at the first edge 1201 of the leading rollers 120 can be designed to be larger than that of the rounding structure 121 at the second edge 1202, for example, a rounded structure with a larger radius can be adopted to weaken the collision and cutting between the first edge 1201 and the incoming material. In addition, for the leading rollers 120 that guide multiple different edges of the vehicle body panel stock in sequence, for example Figure 1 the first three of the four leading ends 12 downstream of the discharging area 102 shown in, the leading rollers 120 therein will contact the outer contour edge of the vehicle body panel stock, the door opening edge at the third tool entry area 1033, the door opening edge at the second tool entry area 1032, etc. in sequence. When the multiple different edges have different extension angles, the first edge 1201 and the second edge 1202 of the leading rollers 120 may respectively serve as the edges that contact the incoming material earlier (that is, the edges that are cut more). In this case, the first edge 1201 and the second edge 1202 can both be designed with a rounding structure 121 with a larger degree of rounding. In the actual implementation, the contact position and shape between the vehicle body panel stock and the rollers can be checked by using Prussian blue inspection, and then the rounding design of the roller edges can be carried out according to the contact situation.
[0036] The above examples mainly illustrate the stock support of the blanking die and the blanking die of the present application. Although only some embodiments of the present application have been described, those of ordinary skill in the art should understand that the present application can be implemented in many other forms without departing from its gist and scope. Therefore, the examples and embodiments shown are regarded as illustrative rather than restrictive, and the present application may cover various modifications and substitutions without departing from the spirit and scope of the technical solution of the present application.
