Window frame cutting device for both corner cutting and its cutting method with space utilization and dimensional precision secured

摘要

The present invention relates to a window frame frame cutting device for both corner cutting and a cutting method for securing space utilization and dimensional precision, and it is possible to use not only the lengthwise straight cut of the window frame frame, but also corner cutting and simultaneous use, and is mainly in the form of a quadrangular cross section. Preventing damage to the outer surface of the window frame frame caused by surface friction by installing front and rear guide support units each equipped with rollers that rub against the outer four sides of the window frame frame, respectively, without a worktable that rubs against the surface when cutting the formed window frame frame. At the same time, it is possible to reduce the installation space of the work table, and by providing the upper, lower, left, and right fixing parts that are in close contact with the outer four surfaces of the window frame frame between the front and rear guide support parts, In order to ensure dimensional precision, the rear end of the window frame 2 seated on the transfer roller 7 spaced apart from each other in the horizontal direction is fixed with a holder 12, and is moved to the rear side of the holder 12. The ball screw 14 connected to the motor 16 is fixed to be positioned in a straight line with the window frame 2 and fixed to the holder 12 by rotation of the ball screw 14 connected to the motor 16 A transfer unit 10 for moving the window frame 2 forward in the horizontal direction; It is provided spaced apart on the front side in the moving direction of the window frame 2, and rubs against the outer 4 surfaces of the window frame 2 on the upper, lower, left, and right sides of the passage space of the window frame 2, respectively. A rear guide support portion 20 provided with guide support rollers 21, 22, 23, and 24; It is provided spaced apart on the front side in the moving direction of the window frame 2 of the rear guide support part 20, and the outer side of the window frame 2 on the upper, lower, left, and right sides of the passage space of the window frame 2 An intermediate guide support part 30 provided with guide support rollers 31, 32, 33 and 34 rubbing against each of the four surfaces; It is provided between the rear guide support portion 20 and the intermediate guide support portion 30, the upper surface, the lower surface of the window frame 2 located between the rear guide support portion 20 and the intermediate guide support portion 30, The middle upper fixing part 210, the middle lower fixing part 220, and the middle left fixing part 230 each provided with a pair of pressing pads 211, 221, 231, 241 that are frictionally fixed while being moved back and forth toward the left and right sides, respectively. And middle right fixing part 240; It is provided between the pair of pressing pads (211, 221, 231, 241) each provided, moving forward and backward, and cutting the window frame frame 2 fixed by pressure by the pair of pressing pads 211, 221, 231, 241 vertically in the longitudinal direction of the window frame frame 2 A straight cutting blade 83; It is provided between the middle upper fixing part 210, the middle lower fixing part 220, the middle left fixing part 230, and the middle right fixing part 240 and the rear guide support part 20, the middle upper fixing part (210), the middle lower fixing part 220, the middle left fixing part 230 and the middle right fixing part 240 and the upper surface, the lower surface of the window frame 2 located between the rear guide support part 20, The rear upper fixing part 110, the rear lower fixing part 120, and the rear left fixing part 130, each provided with a pair of pressing pads 111, 121, 131, 141, each provided with a pair of pressing pads (111, 121, 131, 141) that are frictionally moved back and forth toward the left and right sides, respectively. And rear right fixing part 140; A window frame frame 2 is provided between the press pads 111, 121, 131, 141 and a pair of press pads 211, 221, 231, 241 and moves back and forth while pressing the press pads 111, 121, 131, 141 and a pair of press pads 211, 221, 231, 241 and a window frame frame 2 A first inclined cutting blade 81 for cutting in the first inclined direction in the longitudinal direction of ); The straight cutting blade 83 and the first inclined cutting blade 81 are selectively used according to the shape of the window frame frame 2 to be cut, and the window frame frame 2 of the intermediate guide support part 30 is moved forward. A detection sensor 57 provided spaced apart from the side to detect the approach of the window frame 2 passing through the intermediate guide support 30; It is provided spaced apart from the front side of the window frame 2 of the detection sensor 57 in the moving direction, and the stopper 51 is vertically lowered according to the detection signal of the detection sensor 57 and rubs against the front surface of the window frame 2 It characterized in that it comprises a; front stop portion 50 for stopping the movement of the front side of the frame (2).
