Abstract
Description
Technical Field
[0001] The utility model relates to a plate forming device with a heating function, belonging to the technical field of building material forming equipment. Background Art
[0002] Sheet metal bending is a common processing method used in various industries and for a variety of products.
[0003] During the plate bending process, due to the rebound phenomenon of the material after bending, it is difficult to ensure the forming accuracy of the plate after bending, or the bending operation needs to be repeated many times. Due to the need for multiple bending, it is difficult to improve production efficiency, and the accuracy of the material after bending is difficult to ensure.
[0004] Therefore, how to be efficient and ensure the accuracy of bending forming is an urgent issue that needs to be solved.
[0005] The skin tensioning machine is the closest technology to this utility model. Figure 1 and Figure 2 As shown, the main components of the skin tensioning machine of the traditional sheet forming equipment include a lifting mechanism 1, a tooling table 2, a mold 3, and a bandage 5. The working principle of the skin tensioning machine is: the mold 3 is placed on the tooling platform 2 and fixed, and then the sheet 4 to be bent is placed on top of the mold 3 which is made in advance and meets our surface requirements. The tooling table 2 is pushed by the lifting mechanism 1 so that the mold 3 can move upward until the sheet 4 is tightly clamped between the fixed bandage 5 and the mold 3 and fits tightly with the mold surface, thereby bending the sheet 4 into the curved surface shape we need. However, after removing the fixed bandage 5, the sheet will rebound due to the disappearance of pressure, such as Figure 3 Therefore, it is necessary to continuously adjust the curvature of the mold bending surface to perform multiple bending. Summary of the invention
[0006] The purpose of the utility model is to design a plate forming device with a heating function in order to solve the bending and springback phenomenon of the plate in the prior art.
[0007] The technical solution implemented by the utility model is as follows: a plate forming device with a heating function, including a jacking mechanism, a tooling table, a temperature-resistant bandage and an upper mold base; the device also includes a mold with a groove, a flexible insulation material and a flexible heating belt.
[0008] The grooved mold is placed and fixed on the tooling platform; a layer of flexible heat-insulating material is laid on the upper surface of the grooved mold; the flexible heating belt is arranged on the flexible heat-insulating material at the groove position of the grooved mold; the plate to be bent is placed above the grooved mold with the flexible heat-insulating material and the flexible heating belt laid; below the tooling platform is a lifting mechanism that pushes the tooling table to move upward. The lifting mechanism pushes the tooling table to cause the grooved mold to move upward until the plate is tightly clamped between the fixed heat-resistant bandage and the grooved mold and fits tightly with the surface of the grooved mold. After the fitting is completed, the heating belt is powered on and heated until the temperature of the heated plate reaches the temperature required to complete the molding and is maintained for a certain period of time. Thereby, the plate is bent into the curved shape we need.
[0009] The grooves in the grooved mold can accommodate the thickness of the flexible heating tape and the flexible thermal insulation material.
[0010] The flexible heating belt is separated from the mold groove by a flexible heat insulating material, and the flexible heating belt is in close contact with the bent plate.
[0011] One end of the flexible heating belt is connected to a heating power source.
[0012] The beneficial effect of the utility model is that the utility model improves the mold form and uses flexible heat insulation materials and flexible heating belts to make innovative designs on traditional processing methods, and uses high-temperature heating to make the plate achieve the purpose of plastic deformation, and completes good forming requirements under the action of mechanics. Through this principle, the plate reaches a soft state during the heating process, and then is bent and formed by the action of external force. The plate after being bent by the utility model has a small rebound, which not only improves the precision of plate forming, but also greatly improves the efficiency of plate forming.

[0020] The specific implementation of the utility model is as follows Figure 4-Figure 6 shown.
[0021] This embodiment provides a plate forming device with a heating function, comprising a lifting mechanism 1, a tooling table 2, a mold with grooves 3, a temperature-resistant bandage 5, a flexible heat-insulating material 6 and a flexible heating belt 7.
[0022] The grooved mold 3 is placed and fixed on the tooling platform 2; a layer of flexible heat-insulating material 6 is laid on the upper surface of the grooved mold 3; the flexible heating belt 7 is arranged on the flexible heat-insulating material 6 at the groove position of the grooved mold 3; the plate 4 to be bent is placed above the grooved mold 3 on which the flexible heat-insulating material 6 and the flexible heating belt 7 are laid; and the lower part of the tooling table 2 is a lifting mechanism 1 that pushes the tooling table upward. The lifting mechanism 1 pushes the tooling table 2 to move the grooved mold 3 upward until the plate 4 to be bent is tightly clamped between the heat-resistant bandage 5 fixed by the upper mold seat and the grooved mold 3 and fits tightly with the surface of the grooved mold 3. After the fitting is completed, the flexible heating belt 7 is powered on and heated until the temperature of the heated plate 4 reaches the temperature required for completing the forming and is maintained for a certain period of time. Thus, the plate is bent into the curved shape we need.
[0023] The resistivity of the flexible heating belt in this embodiment is 18.2Ω / m, the power is 150w / m, the voltage is 220V, and the maximum temperature is 350°C. The heat-resistant bandage can withstand a temperature of 350°C.
[0024] The diameter of the mold groove is 10-20mm.
[0025] The working principle of the equipment in this embodiment is as follows: place the grooved mold 3 on the tooling platform 2 and fix it, lay a layer of flexible thermal insulation material 6 on the upper surface of the mold and arrange the flexible heating belt 7 on the flexible thermal insulation material 6 at the groove position of the grooved mold 3, and then place the plate 4 to be bent on the grooved mold 3 with the flexible thermal insulation material 6 and the flexible heating belt 7. The tooling table 2 is pushed by the lifting mechanism 1 so that the grooved mold 3 can move upward until the plate 4 is tightly clamped between the fixed heat-resistant bandage 5 and the grooved mold 3 and fits tightly with the surface of the grooved mold 3, and the edge of the plate 4 can contact the heating belt on the groove. After the fitting is completed, the heating belt 7 is powered on and heated until the temperature of the heated plate 4 reaches the temperature required to complete the molding and then maintained for a certain period of time. Thereby, the plate 4 is bent into the curved shape we need, such as Figure 6shown.
