[0036] Example:
[0037] See also Figure 1-6A hot bending machine for plastic products includes a hot bending machine body 1, a heating mechanism 101 is provided on the hot bending machine body 1, and a curvature adjustment mechanism 102 is installed at the front end of the hot bending machine body 1, and a first frame 103 and a second frame 104 are provided at the rear end of the hot bending machine body 1, which are used to place the workpiece located on the heating mechanism 101 and extending out of the upper part of the hot bending machine body 1, and a distance adjustment component is provided between the first frame 103 and the second frame 104 to adjust the placement position, and side plates 105 are provided on both sides of the second frame 104, and the side plates 105 are connected by a width adjustment component.
[0038] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:
[0039] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The hot bending machine of the present application is combined with a hot bending machine body 1, a heating mechanism 101 and a curvature adjustment mechanism 102. After the hot bending machine body 1 is started to heat the glass cover plate on the heating mechanism 101, the workpiece is on the plane of the hot bending machine body 1. After the bending part is located on the cover plate, the end of the workpiece tail extending out of the hot bending machine body 1 is provided with a first frame 103 and a second frame 104, which are flush with the upper end surface of the hot bending machine body 1. The placement position of the extended workpiece is adjusted by the distance adjustment component so that the corners on both sides of the workpiece fit on the side plate 105. The side plate 105 is designed to be bent to 90 degrees, so that when the heated part of the workpiece is on the heating mechanism 101, the extended part is flush with the side plate 105 to prevent left and right deviation. The side plates 105 on both sides are connected by the width adjustment component, and the distance between the two can be adjusted. In the above case, when the workpieces are of different sizes and have different lengths and widths, the adjustment range is adjusted according to actual needs, so that the workpiece extending out of the hot bending machine body 1 is limited.
[0040] During the specific implementation process, the first frame 103 is located at the rear part of the hot bending machine body 1, and the second frame 104 is located at the rear part of the first frame 103. The sides between the two are connected by a distance adjustment component, wherein the reverse screw 109 is movably installed on one side of the first frame 103 through a bearing, so that the end of the second frame 104 corresponding to the first frame 103 is threadedly connected to the reverse screw 109, and the distance between the side plate 105 and the second frame 104 is adjusted by rotating the reverse screw 109, so as to adjust the placement position of the workpiece extending out of the hot bending machine body 1 and on the first frame 103 and the second frame 104.
[0041] The side plates 105 are designed on both sides inside the second frame 104, and are symmetrically designed to limit the corners of the workpiece at the extension. The width adjustment component is connected to the side plates 105 in the second frame 104 by the pitch adjusting screw 108. The pitch adjusting screw 108 is horizontally installed in the rear part of the second frame 104 through a bearing, and the side plates 105 are threadedly connected to both sides of the pitch adjusting screw 108. By simply turning the handle outside the pitch adjusting screw 108, the pitch adjusting screw 108 can be driven to rotate, so that the side plates 105 on both sides can be moved away from or close to each other. The positioning spacing is adjusted according to the actual workpiece width.
[0042] The present application also provides a positioning shaft 110, which is installed on the other side of the first frame 103. The second frame 104 is slidably connected to the positioning shaft 110 on one side corresponding to the first frame 103, and then when the distance between the second frame 104 and the first frame 103 is adjusted, the other end is driven to move in the same direction on the positioning shaft 110. The positioning shaft 110 is T-shaped and can limit the adjustment range to ensure the stability of the second frame 104 when moving.
[0043] See also Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 8 In the present application, a positioning plate 106 is also provided for limiting the position of the workpiece above so as to better press the heated part of the workpiece onto the upper surface of the heating mechanism 101. The side plate 105 is connected to the positioning plate 106 by a positioning structure. When the tail of the workpiece is located on the side plate 105 and fits in, it is pushed in from the opening of the side plate 105. The opening of the side plate 105 is connected to a roller 107 by rotation. The outer layer of the roller 107 is made of rubber. The support plate 202 is slidably connected to the inside of the slot 2. The support plate 202 and the positioning plate 106 are integrated. The structure is designed in this way. When it drives the workpiece into the positioning pressure plate 106, the force it brings can make the support plate 202 slide on the slide bar 201, stretch the positioning spring 203, and allow the workpiece to fully enter. When it leans against the side plate 105, the force disappears, and the workpiece extending out of the hot bending machine body 1 can be positioned, so that the heated part of the workpiece can be better pressed against the upper surface of the heating mechanism 101 to be heated to prevent it from running away. At the same time, the distance between the positioning pressure plate 106 and the hot bending machine body 1 is designed to be less than the minimum thickness of the workpiece.
[0044] See also Figure 2 , Figure 3 and Figure 7In some embodiments, the present application installs a securing plate 3 below the first frame 103 against the outer wall of the hot bending machine body 1, and installs a limiting frame 301 at the rear end of the hot bending machine body 1. After the first frame 103 is installed and the securing plate 3 is driven into the limiting frame 301, the first frame 103 can be tightly attached to the outer wall of the hot bending machine body 1. After being flush with the upper end surface of the hot bending machine body 1, the securing plate 3 and the limiting frame 301 can be threadedly connected using fastening bolts 302 to install the first frame 103 as a whole on the hot bending machine body 1, and disassemble and relocate according to usage requirements.
[0045] The present application also provides an anti-skid bottom plate 303, which is located at the bottom of the hot bending machine body 1. A plurality of groups of anti-skid strips made of rubber are provided at the bottom of the anti-skid bottom plate 303, which are located on the placement surface of the hot bending machine body 1. When the hot bending machine body 1 is placed on the operating platform, the friction of the contact surface can be increased, thereby improving the stability during placement.
