[0036] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0037] like Figure 1 or Figure 2 As shown, in some embodiments, the utility model provides a 3D curved material self-weight forming and bending device, including a shell 1, a heating cavity 2, a controller 3 and a first electric wire. The cavity surrounded by the shell 1 is the heating cavity 2. A first heating element 5 and a detachable mold assembly 6 are arranged in the heating cavity 2. The detachable mold assembly 6 is arranged on the bottom wall 7 in the heating cavity 2 and is detachably connected to the bottom wall 7 of the heating cavity 2. The first heating element 5 is arranged on the top wall 4 in the heating cavity 2. The controller 3 is connected to the outside of the shell 1, and the first heating element 5 and the detachable mold assembly 6 are connected to the controller 3 through a first electric wire.

[0038] The utility model provides a detachable mold assembly 6 on the bottom wall 7 of the heating chamber 2, and the detachable mold assembly 6 can be adjusted as needed, so that the 3D curved surface material self-weight forming and bending equipment can flexibly prepare 3D curved surface materials with different curvatures.

[0039] There are many ways to connect the detachable mold assembly 6 and the bottom wall 7 in the present invention. For example, in some embodiments, Figure 3 As shown, it can be a snap connection, the bottom wall 7 of the heating chamber 2 is provided with one or more snap grooves 8, the bottom of the detachable mold assembly 6 is provided with one or more corresponding snap parts 9, and the detachable mold assembly 6 is snap-connected with the bottom wall 7 of the heating chamber 2. It can also be a magnetic connection, for example, in some embodiments, such as Figure 4As shown, the bottom wall 7 of the heating chamber 2 is provided with one or more first magnetic attraction parts 10, and the bottom of the detachable mold assembly 6 is provided with one or more corresponding second magnetic attraction parts 11, and the detachable mold assembly 6 is magnetically connected to the bottom wall 7 of the heating chamber 2. In addition, in actual production, the detachable mold assembly 6 can also be bolted to the bottom wall 7. The working temperature of the heating chamber 2 of the utility model is generally 500~700 degrees Celsius. When the utility model adopts magnetic connection, the magnetic attraction part generally selects a magnetic material that can withstand a high temperature of at least 700 degrees without demagnetization, such as a ferrite magnet (the demagnetization temperature reaches above 800 degrees Celsius).

[0040] In order to meet more flexible production needs and produce 3D curved surface materials with different curvatures, the utility model not only adopts a detachable mold assembly 6, but also can design the detachable mold assembly 6 as a mold assembly with adjustable curvature, thereby achieving more flexible adjustment of the curvature of the detachable mold assembly 6. In some embodiments, such as Figure 5 As shown, the detachable mold assembly 6 includes a flexible arc surface 12 and an adjustable frame. The flexible arc surface 12 covers the surface of the adjustable frame, and a clamping hoop is provided on one side of the flexible arc surface 12. The adjustable frame includes a plurality of retractable connectors 13. One end of the retractable connector 13 is connected to a rotatable shaft 14, and the other end is connected to the flexible arc surface 12. The retractable connector 13 includes a first element and a second element that are sleeved. One end of the second element is connected to the rotatable shaft 14, and the other end is sleeved to the first element. The first element supports the flexible arc surface 12 and is fixed by the clamping hoop. The function of the clamping hoop of the utility model is to fix the flexible arc surface 12 and the adjustable frame so that the flexible arc surface 12 can fit the adjustable frame after the adjustable frame is adjusted. In addition, in some embodiments, the aforementioned adjustable frame is generally a cross-section on one side such as Figure 5 The rib structure shown in the figure can change the curvature of the flexible arc surface 12 by different supporting angles of multiple retractable connecting members 13. In order to finely adjust the curvature of the flexible arc surface 12, the retractable connecting member 13 can be a sheet-like supporting structure, such as a structure similar to the blades of a fan, or a thorn-like supporting structure. Specifically, Figure 5 The structure can be a fan-shaped structure, in which each connecting member is perpendicular to the direction of the rotation plane, or a fan-shaped structure composed of multiple thorn-shaped connecting rods.

[0041] In the production process of 3D curved surface materials, temperature control is very important. If the curved surface material is heated unevenly, it is very easy to affect the properties of the curved surface material, such as the curvature, such as the mechanical properties of the material. In order to ensure the uniformity of heating of the 3D curved surface material on the mold, in some embodiments, such as Figure 6As shown, the flexible curved surface 12 is a multi-layer composite structure, which includes a strength support base 15, a heat-conducting mesh 16 and a flexible layer 17 from bottom to top; wherein the strength support base 15 includes a high-temperature resistant alloy grid structure, and the high-temperature resistant alloy grid includes a plurality of mutually nested high-temperature resistant alloy units; the heat-conducting mesh 16 is connected to the strength support base 15 on one side and to the flexible layer 17 on the other side; the flexible layer 17 is an elastic heat-conducting and heat-resistant material. The strength support base 15 and the heat-conducting mesh 16 are both flexible materials, which can change the curvature to a certain extent, and the flexible layer 17 is generally a high-temperature resistant polymer material, which can withstand at least 700 degrees of high temperature without changing its properties, such as ceramic fiber or high-temperature resin material.

[0042] In some embodiments, the number of heating chambers 2 can be one or more. When the number of heating chambers 2 is more than one, such as Figure 7 As shown, multiple heating chambers 2 are arranged inside the housing 1 and are in a stacked structure. This enables multiple 3D curved surface materials to be processed simultaneously, which can greatly improve production efficiency.

[0043] In some embodiments, a plurality of temperature sensors are arranged inside the heating chamber 2, and the temperature sensors are distributed on the top wall 4 and the side wall of the heating chamber 2, and the temperature sensors are connected to the controller 3 through the first wire. The temperature sensor is generally a temperature probe, and when the temperature in the heating chamber 2 detected by the temperature sensor does not reach the temperature set by the controller 3, the controller 3 will control the first heating element to heat, and when the temperature in the heating chamber 2 reaches the set temperature, the temperature sensor will sense it and transmit a signal to the controller 3, and the controller 3 will automatically stop the first heating element 5 from heating. In this way, the preparation temperature of the 3D curved surface material can be controlled more accurately, and the quality of the material can be improved.

[0044] In some embodiments, Figure 1 As shown, in order to reduce heat loss during the heating process, the heating chamber 2 has an upper and lower snap-fit ​​structure and includes a cylinder telescopic machine 18.

[0045] A cylinder telescopic machine 18 is connected to the top of the shell 1. The cylinder telescopic machine 18 includes a cylinder and a telescopic rod. The cylinder is connected to the top of the shell, one end of the telescopic rod is connected to the cylinder, and the other end is connected to the top wall 4.

[0046] The upper and lower buckled structures can ensure that as little heat as possible is transferred to the outside through the air in the heating chamber 2. The cylinder telescopic machine 18 functions to lower the top wall 4, thereby turning the heating chamber 2 into a closed environment.

[0047] like Figure 8As shown, in some embodiments, in order to ensure the cleanliness of the heating chamber 2, a cleaning dust suction device 19 is further provided inside the heating chamber 2. The cleaning dust suction device 19 is detachably connected to the housing 1, and includes a dust suction head 1901, a dust suction pipe 1902, and a dust suction motor body 1903. One end of the dust suction head 1901 is connected to the dust suction pipe 1902, and can penetrate into the heating chamber 2. The other end of the dust suction pipe 1902 is connected to the dust collector motor body 1903, and the dust collector motor body 1903 is detachably connected to the housing 1. At the same time, the dust collector motor body 1903 is connected to the controller 3. When a batch of 3D curved surface materials is completed, after the heating chamber 2 is cooled, the dust suction head 1901 can be inserted into the heating chamber 2 to absorb dust impurities in the heating chamber 2.

[0048] In some embodiments, the dust suction tube 1902 is a retractable device. Specifically, a first through hole can be set in the outer shell, and it can be manually retractable or automatically retractable. The dust suction tube 1902 passes through the first through hole. The dust suction tube 1902 has a multi-layer sleeve structure. For example, when it is a double-layer sleeve, the dust suction tube 1902 includes a first sleeve and a second sleeve. One end of the first sleeve is connected to the vacuum cleaner motor body 1903, and the other end is socketed in the second sleeve. The other end of the second sleeve is connected to the dust head 1901.

[0049] In some embodiments, the controller 3 includes a control panel and a display screen, the control panel is provided with a main power switch of the device, a first heating element control button, a second heating element control button, a cylinder telescopic machine control button and a cleaning and vacuuming device control button, and the display screen displays the current temperature in the heating chamber 2. In some embodiments, a control program is implanted in the controller 3, which can automatically control the heating, cleaning, temperature detection and other working contents in the heating chamber 2.

[0050] The working principle of the utility model is:

[0051] by Figure 1 Taking the equipment as an example, a suitable detachable mold assembly 6 is installed, and then the 3D curved surface material raw material to be processed is placed in the heating chamber 2. It can be placed manually, or an automatic conveying roller can be installed in front of the heating chamber 2 (the automatic conveying roller is also connected to the controller 3) to automatically place the 3D curved surface material raw material in the heating chamber 2, so that the 3D curved surface material raw material is placed on the upper side of the detachable mold assembly 6, and the controller 3 is started to heat the 3D curved surface material raw material, and wait for it to deform in the high temperature environment of the heating chamber 2, so that it is heated and deformed by its own weight and then fits the detachable mold assembly 6. The heating temperature during this period is accurately controlled by the controller 3. When the set process is completed, the 3D curved surface material finished product is taken out.
