[0036] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.
[0037] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
[0038] Example 1
[0039] like Figure 1-6 As shown, Figure 1 The schematic diagram of the embossed plate 1 with reinforcing ribs is composed of a panel 101, a panel embossed surface 102, pressure ribs 103 and a supporting bottom surface 104. Figure 3It is a schematic diagram of a rolling fixture for embossed plates with reinforcing ribs, which consists of a grid-shaped rolling fixture seat 2 and a support block 3. The bottom surface 201 of the rolling fixture is used to contact the support roller 9, and the first support surface 301 is used to support the support bottom surface 104. Figure 5 It is a combination of a ribbed embossed plate 1, a grid-shaped rolling fixture seat 2, and a support block 3. The first support surface 301 abuts against the support bottom surface 104, and the rib bottom surface 105 contacts the upper plane of the grid-shaped rolling fixture seat 2. Figure 6 It is a combination of an embossed plate 1 with reinforcing ribs, a grid-shaped rolling fixture seat 2, and a support block 3. The embossed surface 102 of the panel is pressed by the embossing roller 8. The outer cylindrical surface of the embossing roller 8 is a set pattern mold. The supporting force of the support roller 9 acts on the first supporting surface 301 through the bottom surface 201 of the rolling fixture, supporting the bottom surface 104, so that the embossed surface 102 of the panel is pressed out with a desired pattern under the action of the embossing roller 8. There is a small gap between the support block 3 and the reinforcing rib cavity. Due to the supporting effect of the reinforcing rib, the rolling force can make the deformation of the embossed surface 102 of the panel very small.
[0040] Example 2
[0041] Different from the first embodiment, the grid-shaped rolling fixture seat 2 and the support block 3 can float. Fig.15 As shown, Fig.15 The middle positioning screw 14 is tightened in the screw hole of the floating support block 302 to form a blocking opening H1, the diameter of which is D1. Fig.16 The floating support block 302 has a blocking opening height H2 and a diameter D2. D1, half of the difference and greater than the thermal shrinkage size formed by heated rolling, D3>D2, this embodiment is suitable for heated rolling patterns of light alloy strip grid-shaped reinforcing ribs. When the length is relatively long, generally above 2000mm, taking aluminum alloy as an example, the thermal shrinkage reaches more than 4mm for every 100℃. The general warm forging temperature is around 400℃-500℃. The temperature must be reduced by at least 200℃ from the final forging to the die. Taking 300℃ as an example, there must be a maximum shrinkage of 12mm in the length direction, and the floating amount of the floating support block 302 must be greater than the maximum shrinkage.<h1>
[0042] Example 3
[0043] Different from Example 1, Figure 8 As shown, each support surface can float the roller clamp, and each support surface can float the roller clamp base 4 ( Figure 7), each supporting surface can be floated on the roller-pressing fixture base 4 with a plurality of floating support rod holes 401, the floating support rod hole 401 is perpendicular to the embossed surface, wherein there is a floating support rod 5, the shape of the floating support rod 5 can slide up and down in the floating support rod hole 401, the upper part of the floating support rod 5 has a support head 7, there is an elastic layer 6 between the support head 7 and the floating support rod 5, the upper part of the support head 7 has a second support surface 701, which is used to contact the support bottom surface 104 or the pressure rib bottom surface 105, and the floating support rod 5 also has a limit pin 10, which is used to limit the lower limit of the floating support rod 5, Fig. 9 The floating support rod 5 moves downward under the action of gravity, and the limit pin 10 and each support surface can contact the upper plane of the floating rolling fixture base 4. At this time, the second support surface 701 does not contact the support bottom surface 104. The lower part of the floating support rod 5 has a floating support rod support flange 501, and the end of the floating support rod support flange 501 is the floating support rod support roller contact surface 502. The rolling relationship diagram is shown in Fig.10 As shown, during rolling, part of the support head 7 supports the bottom surface 105 of the pressure rib, and the rolling position relationship is as follows: Fig.17 As shown, the support roller 9 and the floating support rod support roller contact surface 502 contact to make the floating support rod 5 rise, and the second support surface 701 presses against the support bottom surface 104, so that the panel embossed surface 102 is bitten by the embossing roller 8, and the distance between the floating support rod support roller contact surface 502 and the panel embossed surface 102 is constant, and the distance between the embossing roller 8 and the support roller 9 is adjustable, so that the embossing roller 8 can emboss the pattern on the surface of the panel embossed surface 102 with a suitable embossing depth.
[0044] Compared with the first embodiment, the inconsistency of the embossing depth caused by the unevenness of the supporting bottom surface 104 of each reinforcing rib can be avoided. The shape of the floating support rod support roller contact surface 502 at the bottom of each floating support rod 5 is as follows: Fig.12 As shown, when the staggered support rollers 9 are in operation, at least one row of floating support rods 5 is supported at any position, and two rows of floating support rods 5 are supported simultaneously in the staggered area of the floating support rod support roller contact surface 502, ensuring continuous support force during the entire embossing process. Fig. 9 The floating support rod 5 moves downward under the action of gravity, and the limit pin 10 and each support surface can contact the upper plane of the floating rolling fixture base 4. At this time, the second support surface 701 does not contact the support bottom surface 104.
[0045] Fig.13 1 is a top view of a roller mill with supporting rollers. In the figure, a double-sided roller mill support 11 is a roller mill frame, with an embossing roller 8 in the middle. A support roller 9 is provided at the lower part of the embossing roller 8, and a plurality of supporting roller shafts 12 and supporting rollers 13 are provided on both sides. The supporting roller shafts 12 are fixed on the roller mill support 11, and the supporting rollers 13 can rotate freely. The lower parts of both sides of the floating roller clamp base 4 are in contact with the supporting rollers 13 during pressing. The relative contact positions of the floating roller clamp base 4 and the supporting rollers 13 are shown in FIG. Fig.14 As shown, on both sides are the rolling mill brackets 11. It can be seen that the floating roll - rolling fixture base 4 with each support surface is supported by several freely rotatable supporting wheels 13 on both sides. When rolling, the embossing roll 8 and the supporting roll 9 are respectively in contact with the embossing surface 102 of the panel and the contact surface 502 of the floating support rod supporting roll. When the embossing roll 8 and the supporting roll 9 rotate, in addition to the pressure acting on the embossing surface 102 of the panel and the contact surface 502 of the floating support rod supporting roll, there is also a driving force parallel to the embossing surface 102 of the panel. This driving force pushes the embossed plate 1 with reinforcing ribs and the entire floating roll - rolling fixture with each support surface forward, while the weight of the floating roll - rolling fixture base 4 with each support surface is supported by the supporting wheels 13. The floating support head support surface 7031 abuts against the supporting bottom surface 104, and the second support surface 701 in Embodiment 3 abuts against the bottom surface 105 of the pressure - strengthening rib without change.
[0046] Embodiment 4
[0047] Different from Embodiment 3, in combination with the hot - rolling situation of Embodiment 2, the support head 7 supporting the supporting bottom surface 104 is set as Fig.18 the double - layer structure shown. The floating support head support seat 702 is fixed relative to the floating support rod 5, and the floating support head 703 is installed on the upper part of the floating support head support seat 702 and can float freely relative to the floating support head support seat 702. As Fig.19 shown, the positioning screw 14 in the figure is tightened in the screw hole of the floating support head 703 to form a blocking port H1, and the diameter of this section is D1. Fig. 20 This is the floating support head support seat 702, which has a blocking port height dimension of H2 and a diameter D2, H4 < H3, enabling the floating support head combination composed of the floating support head 703 and the positioning screw 14 to move freely. D2 > D1, and half of the difference is greater than the thermal shrinkage dimension generated by hot - rolling, D3 > D2.
[0048] Embodiment 5
[0049] Different from Embodiment 3 and Embodiment 4, as Fig.11 shown, the difference is that the floating roll - rolling fixture base 4 with each support surface is divided into upper and lower layers, namely the base upper plate 402 and the base lower plate 403, which can make the supporting distances at both ends of the floating support rod 5 larger, make the floating support rod 5 more stable, and at the same time reduce the weight of the floating roll - rolling fixture base 4 with each support surface and improve the stability.
[0050] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
