The telescopic end of the electric push rod 103 passes through the top wall of the inner cavity of the fixing frame 102 and is fixedly connected with a pushing frame 104. The pushing frame 104 is used to push and bend the plate. Bend, the top wall of the inner cavity of the shell 100 is evenly fixedly connected with a clamping spring 105, which facilitates pushing the support frame 106 through the clamping spring 105, and the clamping spring 105 adopts a hard spring, and the top wall of the clamping spring 105 is fixedly connected with the support frame 106, which facilitates clamping and limiting the plate through the support frame 106, and the front and rear side walls of the inner cavity of the shell 100 are provided with sliding grooves, which facilitate the movement of the support frame 106 to limit and guide the movement, and the support frame 106 is located in the inner cavity of the sliding groove, and the top wall of the support frame 106 is provided with a heating rod 107, which facilitates heating the plate through the heating rod 107, which facilitates subsequent bending.
[0021] The plate is then heated and softened by heating rod 107, and the plate is pushed downward by electric push rod 103, and the plate is bent by cooperation of support roller 101 and push frame 104. The bending angle is adjusted by adjusting the downward pressure position of push frame 104, which can make the device convenient for clamping and limiting the plate during bending to avoid deviation, and is beneficial for the device to bend the designated position of polycarbonate flame retardant plate.
[0022] The left side of the front and rear side walls of the inner cavity of the shell 100 are rotatably connected to the double-headed screw 108, which can easily drive the two sets of limit plates 109 to move toward or away from each other. The front and rear sides of the outer wall of the double-headed screw 108 are screwed to the limit plates 109, which can facilitate the limitation of the plates. The top walls of the limit plates 109 are evenly provided with grooves, and the limit plates 109 are located between the left support rollers 101.
