The upper part of the mold cavity has an opening for the upper knife mold 4012 to enter. The fixed mold 404 and the movable mold 405 is provided with a workpiece positioning tool 419 at the opening. The feeding mechanism 3 transfers the workpiece to the workpiece positioning tool 419. In the clamping state, the lowering device 4011 drives the upper die 4012 to descend, and the sheet-shaped workpiece Press into the mold cavity to complete the bending. At this time, the movable mold 405 is in a locked state; the mounting platform 403 is provided with a blanking port 420, which is set under the mold cavity, and is in a locked state , The movable mold 405 closes the blanking port 420. After the bending is completed, the upper die 4012 is lifted up, and the movable mold 405 is driven by the clamping mechanism 406 to move away from the fixed mold 404, exposing the lower blanking port 420, bending The workpiece falls into the collecting trough 5 below the blanking port 420 to complete collection.
[0027]Such asFigure 3-4As shown, in this embodiment, the loading mechanism 2 includes a loading tool 201 and a jacking device. The loading tool 201 is provided on the body 1, and the loading tool 201 has a workpiece containing cavity. The workpiece to be bent is placed in the workpiece accommodating cavity. The lifting device includes a lifting motor 202, a lifting screw 203, and a lifting plate 204 arranged on the lifting screw 203 through a nut. The lifting motor 202 is passed through a timing belt. 205 drives the lifting screw 203 to rotate, the lifting plate 204 is provided with a plurality of lifting columns 206, the lifting columns 206 penetrate the bottom of the loading tool 201 and extend into the workpiece accommodating cavity. The top of the lifting column 206 is provided with a lifting plate 207, and the workpiece is lifted on the lifting plate 207. When the lifting motor 202 rotates, the lifting screw 203 is driven to rotate by the timing belt 205, thereby driving the lifting plate 204 to rise and lift the workpiece upward The lifted workpiece is fed into the bending mechanism 4 by the feeding mechanism 3.
[0028]Such asFigure 5 As shown, in this embodiment, the feeding mechanism 3 is set on the body 1 through a mounting base 301, and the movement mechanism includes a timing belt sliding table 302 fixed on the mounting base 301 and a timing belt sliding table 302. The lifting and reclaiming mechanism includes a reclaiming arm 303 and a lifting drive device 304. The rear end of the reclaiming arm 303 is slidably connected to the timing belt slide 302 through a guide rail, and the lifting drive The moving end of the device 304 is connected to the reclaiming arm 303 through a connecting block, and the workpiece suction mechanism 305 is provided at the front end of the reclaiming arm 303. Specifically, the workpiece suction mechanism 305 may be a cross bar with a suction cup, which is driven by the timing belt sliding table 302 to reciprocate between the workpiece positioning tool 419 and the workpiece receiving cavity to complete the transfer of the workpiece.
[0029]In this embodiment, the clamping mechanism 406 is asFigure 6 As shown, it includes a slide plate 408 slidably mounted on the mounting platform 403 through a slide plate guide rail 407, a slide plate driving device 409, and a toggle mechanism 410 provided on both sides of the slide plate 408. The toggle mechanism 410 includes an angle bracket 411 , The first connecting rod 412 and the second connecting rod 413, the angle bracket 411 has a first hinge point 414, a second hinge point 415 and a third hinge point 416, wherein the first hinge point 414 at the bottom through a fixed pin It is hinged to the mounting platform 403. The two ends of the first link 412 are hinged to the sliding plate 408 and the second hinge point 415 respectively. The two ends of the second link 413 are hinged to the third hinge point 416 and the movable mold 405 The side. The specific movement mode of the clamping mechanism 406 is: in the mold opening state (Figure 7 ), the movable mold 405 and the fixed mold 404 are far away from each other, the sliding plate 408 is in a position far from the movable mold 405, the first connecting rod 412 pulls the angle bracket 411 to rotate a certain angle, so that the first hinge point 414 and the third hinge point 416 between The connecting line and the second connecting rod 413 have a small included angle (for the convenience of the following description, the included angle is named α); when clamping (Figure 8 ), the sliding plate 408 moves in the direction of the sliding plate guide rail 407 toward the movable mold 405, and the angle bracket 411 rotates outward under the push of the first connecting rod 412, so that α becomes larger, so that the second connecting rod 413 pushes the movable mold 405 Move in the direction of the fixed mold 404, and finally the movable mold 405 and the fixed mold 404 abut against each other. Preferably, when the movable mold 405 and the fixed mold 404 collide, α is 180°. At this time, the angle bracket 411 and the second connecting rod 413 are shared The movable mold 405 is pressed against the fixed mold 404, and the mold clamping is firmer. The two toggle link mechanisms 410 are set to act on the two ends of the movable mold 405 respectively. They have the advantages of uniform force, stable mold opening speed, stable mold clamping force, and low power required. The distance between the two toggle mechanisms 410 It depends more on the length of the two first connecting rods 412. Therefore, by providing a longer-length first connecting rod 412, a longer-length movable mold 405 can be smoothly locked.
[0030]In order to ensure the smooth movement of the movable mold 405, the mounting platform 403 is also provided with a movable mold guide rail 417, the movable mold 405 is slidingly fitted with the movable mold guide rail 417, and the mounting table 403 is mounted on the movable mold 405 Both ends are also provided with mold positioning blocks 418, the mold positioning blocks 418 are provided with an embedded groove, and both ends of the movable mold 405 are provided with embedded blocks, and the embedded blocks are slidably embedded in the embedded grooves.
