Description

Technical Field

[0001] The utility model belongs to the technical field of hot bending processing, and specifically relates to a hot bending device for processing acrylic plates. Background Art

[0002] Acrylic sheet, also known as plexiglass or PMMA (polymethyl methacrylate), is a transparent plastic material used in a wide variety of applications. Acrylic sheet has the following characteristics: High transparency: Acrylic sheet has a light transmittance of up to 92%, making it clearer than ordinary glass. Lightweight: Compared to glass, acrylic sheet is lighter, making it easier to transport and install. High impact resistance: Acrylic sheet has an impact resistance more than ten times that of ordinary glass and is resistant to breakage. Easy processing: It can be processed through cutting, drilling, hot bending, and other methods to meet different needs. Weather resistance: Its excellent weather resistance makes it suitable for outdoor use.

[0003] Acrylic sheet hot bending is a commonly used processing method. After heating the acrylic sheet to a certain temperature, it will become soft and can then be bent into shape. There are many different types of hot bending devices on the market, but the structural design of most hot bending devices is too simple. In actual use, they can usually only complete linear heating. After heating is completed, the acrylic sheet is manually bent and shaped in the heating part. The overall function is relatively simple. When the acrylic sheet needs to be bent as a whole, special flat heating equipment is generally required, which increases the production and processing costs. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a hot bending device for processing acrylic plates.

[0005] The technical solution adopted to solve the above technical problems is: a hot bending device for processing acrylic plates, comprising a planar hot bending mechanism for heating the acrylic plate to be processed, the rear end of the planar hot bending mechanism being rotatably connected to a heat preservation mechanism via a hinge, and the front end of the planar hot bending mechanism being fixedly connected to a heat insulation protection mechanism;

[0006] A linear heat bending mechanism is installed at the inner center of the heat preservation mechanism for linear heating of the acrylic plate to be processed;

[0007] Support pads are fixedly connected to the bottom corners of the planar hot bending mechanism and the rear end corners of the heat preservation mechanism.

[0008] Furthermore, the planar hot bending mechanism includes a support frame, a heat insulating pad is fixedly connected to the middle of the support frame, an electric heating tube disc is installed above the heat insulating pad, and a heating panel is fixedly installed on the top of the support frame.

[0009] By the technical scheme, the planar thermal bending mechanism can complete overall heating of the to-be-processed acrylic plate, so that the to-be-processed acrylic plate can be bent and shaped as a whole. In specific work, when the electric heating tube disc is connected to the power supply, the electric heating tube disc starts to heat, and the heat is conducted to the heating panel through the air. At this time, the to-be-processed acrylic plate can be heated by being placed horizontally on the heating panel, so that the to-be-processed acrylic plate is softened, and subsequent bending and shaping can be performed.

[0010] Further, the support rack rear end is provided with a heat dissipation hole.

The heat preservation cover inner side is provided with a groove, and when the heat preservation cover is rotated and closed above the planar thermal bending mechanism, it will not affect the to-be-processed acrylic plate. At the same time, since the distance between the heat preservation cover and the planar thermal bending mechanism is small, better heat preservation effect can be achieved.

[0014] Further, the heat insulation protection mechanism includes a heat insulation guard fixed to the front end of the support rack, one side of the heat insulation guard is provided with a wiring socket, and the front end of the heat insulation guard is provided with a control switch electrically connected with the electric heating tube disc.

[0017] By the above technical scheme, the linear heat bending mechanism can complete independent linear heating, when the to-be-processed acrylic plate needs to be linearly bent, the heat preservation mechanism can be adjusted to a horizontal state, when the linear electric heating pipe is connected to the power supply, the linear electric heating pipe will quickly heat up, because the center of the cover plate is provided with the heating hole, the heat dissipated by the linear electric heating pipe can be concentrated and dissipated through the heating hole, therefore, when the to-be-processed acrylic plate is horizontally placed in the groove and the heating position is adjusted, the heat dissipated at the heating hole can quickly complete the linear heating of the to-be-processed acrylic plate, so as to facilitate subsequent bending and shaping, in addition, a plurality of internal thread holes are arranged in the groove, a detachable limiting component can be additionally arranged on the groove according to the bending position requirement, so as to quickly complete the accurate positioning of the to-be-processed acrylic plate, so as to ensure the processing precision and processing efficiency.

[0018] Further, two through holes are arranged at the outer side of the heat preservation cover and penetrate the water cooling interface and the back-shaped heat dissipation cavity.

[0019] By the above technical scheme, the external cooling water pipe can be connected through the two water cooling interfaces, and the cooling water can be injected into the back-shaped heat dissipation cavity, so as to complete the cooling and temperature reduction of the heating assembly, and prevent a large amount of heat from being conducted to the heat preservation mechanism.
