Abstract
Description
Technical Field
[0001] This utility model relates to the field of acrylic sheet processing technology, and more specifically, to an acrylic sheet hot bending forming device. Background Technology
[0002] Acrylic is a general term for acrylic and methacrylic chemicals. It includes monomers, sheets, granules, resins, and composite materials. Acrylic sheets are polymerized from methyl methacrylate monomer (MMA), i.e., polymethyl methacrylate (PMMA) sheets, a type of plexiglass processed with special techniques. It is known as the "Queen of Plastics." The research and development of acrylic has a history of over a hundred years. Acrylic sheets are heated and bent into different angles according to requirements.
[0003] However, existing devices typically use templates with fixed angles to bend acrylic sheets during the bending process. But the bending angle of acrylic sheets varies depending on the application requirements, so multiple fixed templates are needed, which increases the processing cost. Therefore, we propose an acrylic sheet hot bending forming device to solve the above-mentioned problems. Utility Model Content
[0004] 1. Technical problems to be solved
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an acrylic sheet hot bending forming device. It can use the control host to precisely control the angular displacement of the stepper motor. While the shaft head and the frame rotate, the rotating seat is driven to flip, thereby hot bending and deforming the acrylic sheet. The pressure plate can be hot bent into different angles according to the requirements, reducing the production cost.
[0006] 2. Technical Solution
[0007] To solve the above problems, the present invention adopts the following technical solution.
[0008] An acrylic sheet hot bending forming device includes a frame, a first electric heating plate mounted on the frame, a rotating seat mounted on one side of the first electric heating plate, and a second electric heating plate mounted on the rotating seat. The rotating seat has a shaft head welded to its side wall near the first electric heating plate, which is rotatably connected to the frame. A stepper motor with a power output end connected to the shaft head is mounted on the outer side wall of the frame.
[0009] The outer side walls of the frame and the rotating seat are fixedly connected with adjustment plates, and the adjustment plates have adjustment holes through a straight line structure.
[0010] Both the first electric heating plate and the second electric heating plate are fitted with pressure plates. Both ends of the pressure plates are fitted with hexagonal bolts that pass through the adjustment holes. Locking nuts that abut against the lower surface of the adjustment plate are screwed onto the hexagonal bolts.
[0011] Below the rotating base is a mounting base that is fixedly connected to the frame, and a control host and a temperature controller are respectively mounted on the mounting base.
[0012] Furthermore, the initial position of the second electric heating plate is on the same horizontal plane as the first electric heating plate.
[0013] Furthermore, a bearing is installed at the junction of the shaft head and the frame, and the power output shaft of the stepper motor is connected to the shaft head via a coupling.
[0014] Furthermore, the outer diameter of the hexagonal bolt is adapted to the width of the adjusting hole.
[0015] Furthermore, the pressure plate is made of alumina ceramic.
[0016] Furthermore, a gap is left between the first electric heating plate and the second electric heating plate.
[0017] Furthermore, the output terminal of the control host is electrically connected to the input terminal of the stepper motor;
[0018] The input terminals of both the first and second electric heating plates are electrically connected to the output terminal of the temperature controller.
[0019] 3. Beneficial effects
[0020] Compared with existing technologies, the advantages of this utility model are:
[0021] (1) In this solution, by using the control host to precisely control the angular displacement of the stepper motor, the shaft head rotates in conjunction with the frame, while driving the rotating seat to flip, thereby hot bending and deforming the acrylic sheet. The pressure plate can be hot bent into different angles according to the requirements, thus reducing the production cost.
[0022] (2) In this solution, the hexagonal bolts installed at the end of the pressure plate are used to slide in conjunction with the adjustment holes opened on the adjustment plate so that the end of the pressure plate corresponds to the end of the acrylic sheet. Then, the hexagonal bolts are tightened with locking nuts, and the acrylic sheet is pressed by the pressure plate. This solution is applicable to acrylic sheets of different lengths and improves applicability. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0031] Example:
[0032] Please see Figure 1-5 An acrylic sheet hot bending forming device includes a frame 1, a first electric heating plate 2 mounted on the frame 1, a rotating seat 3 mounted on one side of the first electric heating plate 2, and a second electric heating plate 4 mounted on the rotating seat 3. The rotating seat 3 has a shaft head 5 welded to the side wall near the first electric heating plate 2, which is rotatably connected to the frame 1. A stepper motor 6 with a power output end connected to the shaft head 5 is installed on the outer side wall of the frame 1.
[0033] Adjustment plates 7 are fixedly connected to the outer side walls of the frame 1 and the rotating seat 3 respectively. Adjustment plates 7 have adjustment holes 8 through a straight line structure.
[0034] Pressure plates 9 are attached to both the first electric heating plate 2 and the second electric heating plate 4. Hexagonal bolts 10 with through-holes 8 are installed at both ends of the pressure plates 9. Locking nuts 11 that abut against the lower surface of the adjustment plate 7 are screwed onto the hexagonal bolts 10.
[0035] Below the rotating base 3 is a mounting base 12 that is fixedly connected to the frame 1. The control host 13 and the temperature controller 14 are respectively mounted on the mounting base 12.
[0036] It should be noted that when using this acrylic sheet hot bending forming device, the working temperature of the first electric heating plate 2 and the second electric heating plate 4 is first adjusted and controlled by the temperature controller 14. Then, the acrylic sheet to be bent is placed on the first electric heating plate 2 and the second electric heating plate 4. Then, the hexagonal bolts 10 installed at the end of the pressure plate 9 slide in conjunction with the adjustment holes 8 opened on the adjustment plate 7, so that the end of the pressure plate 9 corresponds with the end of the acrylic sheet. Then, the hexagonal bolts 10 are tightened by the locking nut 11, and the acrylic sheet is pressed by the pressure plate 9. Then, the angular displacement of the stepper motor 6 is precisely controlled by the control host 13. While the shaft head 5 rotates in conjunction with the frame 1, it drives the rotating seat 3 to rotate, thereby hot bending and deforming the acrylic sheet.
[0037] like Figure 1 As shown, the initial position of the second electric heating plate 4 is on the same horizontal plane as the first electric heating plate 2, and there is a gap between the first electric heating plate 2 and the second electric heating plate 4.
[0038] It should be noted that by ensuring that the initial position of the second electric heating plate 4 is horizontal with that of the first electric heating plate 2, the bending accuracy of the acrylic sheet can be guaranteed. At the same time, the second electric heating plate 4 avoids interference with the first electric heating plate 2 during the folding process.
[0039] like Figure 3 , Figure 4 As shown, a bearing is installed at the junction of the shaft head 5 and the frame 1, and the power output shaft of the stepper motor 6 is connected to the shaft head 5 through a coupling.
[0040] It should be noted that the friction between the shaft head 5 and the frame 1 is reduced, while ensuring that the power transmitted by the stepper motor 6 can be transmitted to the shaft head 5 to drive the rotating seat 3 to rotate.
[0041] like Figure 4 , Figure 5 As shown, the outer diameter of the hexagonal bolt 10 is matched with the width of the adjusting hole 8;
[0042] It should be noted that the stability of the pressure plate 9 during the positioning process of the acrylic sheet must be ensured.
[0043] like Figure 5 As shown, pressure plate 9 is made of alumina ceramic.
[0044] It should be noted that preventing the pressure plate 9 from conducting heat facilitates manual adjustment of the pressure plate 9 by the workers.
[0045] The output terminal of the control host 13 is electrically connected to the input terminal of the stepper motor 6;
[0046] The input terminals of the first electric heating plate 2 and the second electric heating plate 4 are both electrically connected to the output terminal of the temperature controller 14.
[0047] In use: First, use the thermostat 14 to adjust and control the working temperature of the first electric heating plate 2 and the second electric heating plate 4. Then, place the acrylic sheet to be bent on the first electric heating plate 2 and the second electric heating plate 4. Then, slide the hexagonal bolt 10 installed at the end of the pressure plate 9 in conjunction with the adjustment hole 8 opened on the adjustment plate 7 so that the end of the pressure plate 9 corresponds with the end of the acrylic sheet. Then, tighten the hexagonal bolt 10 with the locking nut 11 and use the pressure plate 9 to press the acrylic sheet. Then, use the control host 13 to precisely control the angular displacement of the stepper motor 6. While the shaft head 5 rotates with the frame 1, it drives the rotating seat 3 to flip, thereby deforming the acrylic sheet by heat bending.
[0048] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
