FRP is fiber reinforced plastic, which generally refers to reinforced plastics with glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, with glass fiber or its products as reinforcement materials, called glass fiber reinforced plastic, or FRP, which is different from tempered glass;

[0003] During the steel plate processing, some fiberglass skirt panels need to be bent, and the required bending angle will also change depending on the usage scenario. The existing bending mechanism is not convenient for adjusting the bending angle when in use, resulting in a low bending application range for the fiberglass skirt panels. Utility Model Content

[0004] In view of this, the utility model provides a skirt plate processing and bending device, which is used to solve the technical problem that the bending angle of the bending mechanism is not convenient to be adjusted when in use, resulting in a low application range.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a skirt plate processing and bending device, which has a supporting base, wherein two lower hinged seats are symmetrically fixedly installed on the supporting base, the fixed end of the lifting cylinder is hinged on the lower hinged seat, the movable end of the lifting cylinder extends upward and the end is hinged with an upper hinged seat, and the upper hinged seat is fixedly installed with a bending table;

[0007] The two bending tables are hingedly arranged at one end close to each other, and each of the two bending tables is provided with a group of first pressing roller assemblies, and two rows of first mounting holes are transversely opened on the bending tables, and the first pressing roller assemblies are connected to the bending tables through the first mounting holes;

Two rows of second mounting holes are vertically opened on the fixed plates, and the second pressure roller assembly is connected to the fixed plates through the second mounting holes.

[0009] On the basis of the above technical solution, the skirt plate processing and bending device of the utility model can also be improved as follows:

[0010] Furthermore, a group of the first pressure roller assemblies includes two bearing seats, each of which has a first bearing fixedly installed therein, and a first rotating roller fixedly installed therein, and one end of the first rotating roller extends forward to the outside of the first bearing.

[0011] Furthermore, first screw holes are provided on both sides of the first pressure roller assembly, and the first screw holes are connected to the corresponding first mounting holes through a first connecting member.

[0012] Furthermore, the second pressure roller assembly includes a lifting plate, and second bearings are fixedly mounted on the two lifting plates. A second rotating roller is fixedly mounted between the two second bearings, and both ends of the second rotating roller extend to the outside of the second bearings.

[0013] Furthermore, second screw holes are provided on both sides of the second pressure roller assembly, and the second screw holes are connected to the corresponding second mounting holes through second connecting members.

[0014] Furthermore, an adjusting wheel for rotating the second rotating roller is fixedly mounted on the rear end of the second rotating roller, and a positioning block is fixedly mounted on the front end of the second rotating roller, wherein a limiting plate is engaged in the positioning block.

[0032] like Figure 1-4 As shown, the utility model provides a skirt plate processing and bending device, which has a support base 1, wherein two lower hinge seats 41 are symmetrically fixedly installed on the support base 1, and the fixed end of the lifting cylinder 4 is hinged on the lower hinge seat 41, and the movable end of the lifting cylinder 4 extends upward and the end is hinged with an upper hinge seat 42, and the upper hinge seat 42 is fixedly installed with a bending table 2;

[0033] The two bending tables 2 are hingedly arranged at one end close to each other, and a group of first pressing roller assemblies 5 are respectively arranged on the two bending tables 2. Two rows of first mounting holes 3 are horizontally opened on the bending tables 2, and the first pressing roller assemblies 5 are connected to the bending tables 2 through the first mounting holes 3;

[0034] Fixed plates 12 are fixedly installed on the front and rear walls of the support base 1. The two fixed plates 12 are slidably connected to the second pressure roller assembly 6 on the side away from the bending table 2. Two rows of second mounting holes 13 are vertically opened on the fixed plates 12, and the second pressure roller assembly 6 is connected to the fixed plates 12 through the second mounting holes 13.

[0035] Optionally, in the above technical solution, a group of first pressure roller assemblies 5 includes two bearing seats 51, each of which has a first bearing 52 fixedly installed therein, and a first rotating roller 53 fixedly installed therein, and one end of the first rotating roller 53 extends forward to the outside of the first bearing 52.

[0036] Optionally, in the above technical solution, first screw holes 50 are opened on both sides of the first pressure roller assembly 5 , and the first screw holes 50 are connected to the corresponding first mounting holes 3 through a first connecting member 54 .

[0037] Optionally, in the above technical solution, the second pressure roller assembly 6 includes a lifting plate 61, and second bearings 62 are fixedly installed on the two lifting plates 61, and a second rotating roller 63 is fixedly installed between the two second bearings 62, and both ends of the second rotating roller 63 extend to the outside of the second bearings 62.

[0038] Optionally, in the above technical solution, second screw holes 60 are opened on both sides of the second pressure roller assembly 6 , and the second screw holes 60 are connected to the corresponding second mounting holes 13 through second connecting members 64 .

[0039] Optionally, in the above technical solution, an adjusting wheel 65 for rotating the second rotating roller 63 is fixedly mounted at the rear end of the second rotating roller 63 , and a positioning block 66 is fixedly mounted at the front end of the second rotating roller 63 , and a limiting plate 67 is engaged in the positioning block 66 .

[0040] The second rotating roller 63 is rotatably connected to the lifting plate 61.

[0041] The front end of the first rotating roller 53 is fixedly mounted with an anti-slip sleeve 55, which can abut against the limit plate 67. The clamping arrangement facilitates the removal of the limit plate 67 from the positioning block 66.

[0042] During processing, the limiting plate 67 is removed so that the rotation of the second rotating roller 63 is not restricted. When not processing, the limiting plate 67 is installed on the second rotating roller 63. Both the two first rotating rollers 53 can limit the limiting plate 67 to avoid accidentally hitting the second connecting member 64 so that the second rotating roller 63 drives the limiting plate 67 to rotate too much.

[0043] The greater the upward movement of the movable end of the lifting cylinder 4, the greater the degree to which the skirt plate is bent;

[0044] The height of the second rotating roller 63 should be as low as possible while ensuring that the skirt plate can pass through, so that the lifting height required by the lifting cylinder 4 is as small as possible, reducing the lift of the lifting cylinder 4 and ensuring the bending processing efficiency.

[0045] Working principle:

[0046] In the initial state, the bending tables 2 on both sides are parallel to the ground, and the first pressing roller assembly 5 and the second pressing roller assembly 6 are adjusted to a suitable position. When the distance between the first rotating rollers 53 on both sides is larger, the bending radius of the skirt plate is larger, and when the distance between the first rotating rollers 53 on both sides is smaller, the bending radius of the skirt plate is smaller.

[0047] During processing, one end of the skirt piece is passed through the lower side of the second rotating roller 63 and the upper side of the first rotating roller 53, so that both ends of the skirt piece are overlapped on the first rotating roller 53. At this time, the skirt piece is clamped by the first rotating roller 53 and the second rotating roller 63 on both sides;

[0048] The lifting cylinder 4 is started to move its movable end upward, driving the bending tables 2 on both sides to rotate upward in an arc around the hinged end. The upward rotation of the bending tables 2 causes the first rotating rollers 53 on both sides to lift the skirt plate parts and bend them upward, thereby bending the skirt plate parts.

[0049] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
