[0026] Figures 1-5In one embodiment of this utility model, a bending device for a spacer bar in insulating glass includes a base 1. The base 1 has two sets of symmetrically distributed positioning rods 2 and pushers 5 corresponding to the gaps between the two sets of positioning rods 2. The base 1 also has an adjustment mechanism 3 for synchronously adjusting the angles of the two sets of positioning rods 2, and a pushing mechanism 4 for driving the pushers 5. The adjustment mechanism 3 includes two sets of symmetrically distributed first racks 303 slidably installed within the base 1. Both sets of positioning rods 2 are rotatably connected to the base 1 via mounting shafts 301, and both sets of mounting shafts 301 are fitted with first gears 302. The two sets of first racks 303 are respectively corresponding to the two sets of first gears 302, and the two sets of first racks 303 are meshed with their respective first gears 302. The two sets of first racks 303 are fixedly connected by a connecting frame 315. A lead screw 304 is rotatably installed within the base 1. 4. A through-connector 315 is threadedly connected to the connecting frame 315. The base 1 is equipped with two sets of angle sensors 305 corresponding to the positioning rods 2. The mounting shafts 301 on the two sets of positioning rods 2 are fixedly connected to the rotation shafts of the corresponding angle sensors 305. It adopts a synchronous linkage double positioning rod 2 structure and an adjustable pusher 5 system, which can realize stepless adjustment of the bending angle of the spacer strip, significantly improving the processing flexibility and applicability. The second gear 310 and the second rack 309 on the positioning rod 2 are driven by the clamping mechanism of the first spring 308 and the second spring 314, which not only ensures the bending accuracy but also avoids material damage. The modular push assembly can accurately control the bending force and stroke through the screw 404 and the solenoid 406 dual-stage transmission. This device is not only suitable for the batch processing of conventional rectangular spacer strips, but also meets the special bending requirements of irregularly shaped insulating glass, greatly reducing the mold replacement frequency.
[0027] In this embodiment, reference Figure 2As shown, the propulsion mechanism 4 includes a fixed rod 401 fixedly mounted on the base 1, a first push rod 402 slidably mounted inside the fixed rod 401, a second push rod 403 slidably mounted inside the first push rod 402, a push frame 5 movably engaging with the second push rod 403, a screw 404 rotatably mounted inside the fixed rod 401, and a screw tube 406 rotatably mounted inside the first push rod 402. The screw 404 passes through the first push rod 402 and is threadedly connected to it, while the screw tube 406 passes through the second push rod 402. 03 is threadedly connected to the second push rod 403. Two sets of symmetrically distributed keyways 405 are provided inside the screw rod 404. Two sets of symmetrically distributed key blocks 407 are provided inside the screw tube 406, with the key blocks 407 corresponding to the keyways 405. The screw tube 406 is slidably sleeved with the screw rod 404 through the key blocks 407 and keyways 405. The spacer strip to be bent is placed between the two positioning rods 2 and the pusher 5. Different angle pushers 5 can be selected according to the actual bending angle required. The motor in the fixed rod 401 drives... During the rotation of the screw 404, the first push rod 402 slides under the limiting action of the fixed rod 401. The first push rod 402 drives the screw tube 406 to slide synchronously. Under the limiting action of the key block 407 and the keyway 405, the screw tube 406 rotates synchronously with the screw 404. Therefore, under the limiting action of the first push rod 402, the second push rod 403 slides in the first push rod 402, causing the push frame 5, which is engaged with the second push rod 403 at a specific angle, to move towards the two sets of positioning rods 2. The motor drives the lead screw 304 in the base 1 to rotate. Under the limiting action of the base 1, the connecting frame 315 drives the two sets of first racks 303 to slide synchronously in the base 1. With the help of the two sets of first gears 302, the two sets of mounting shafts 301 drive the two sets of positioning rods 2 and the spacer fixed on the positioning rods 2 to bend synchronously. During this process, the angle sensor 305 monitors the rotation angle of the two sets of mounting shafts 301 in real time. With the help of the pusher 5 to squeeze the spacer, the bending process of the spacer at different angles is completed.
[0028] In this embodiment, reference Figure 3 and Figure 5As shown, two sets of symmetrically distributed slides 306 are slidably mounted on each of the two sets of positioning rods 2. A first spring 308 is sleeved on each of the two sets of slides 306, with both ends of the first spring 308 fixedly connected to the slide 306 and the positioning rod 2, respectively. Clamping plates 307 are fixedly mounted on each of the two sets of slides 306, and the clamping plates 307 are distributed on both sides of the positioning rod 2. Two sets of slides 313, corresponding to the slides 306, are fixedly mounted in the positioning rod 2. A second rack 309 is fixedly mounted on each of the two sets of second racks 309, and a second gear 310 is provided between the two sets of second racks 309. The second gear 310 meshes with the two sets of second racks 309, and the second gear 310 is rotatably connected to the positioning rod 2 via a handle 311. A torsion spring 312 is sleeved on the handle 311, with both ends of the torsion spring 312 fixedly connected to the second gear 310 and the positioning rod 2, respectively. The slide bar 313 is slidably connected to the corresponding slide rod 313, and two sets of symmetrically distributed second springs 314 are sleeved on the slide rod 313. The two ends of the two sets of second springs 314 are fixedly connected to the slide 306 and the positioning rod 2, respectively. When the handle 311 on the positioning rod 2 is rotated, it drives the second gear 310 to rotate, which, together with the two sets of second racks 309, pushes the two sets of slides 306 outward synchronously, thereby driving the two sets of clamps 307 to slide outward synchronously away from the corresponding positioning rod 2. At this time, spacers of different models can be placed between the clamps 307 and the positioning rod 2. After releasing the handle 311, the spacers are fixed between the clamps 307 and the positioning rod 2 under the action of the torsion spring 312, the first spring 308 and the second spring 314. This fixing method will not damage the spacers, and allows the spacers to slide on the positioning rod 2 during the bending process, ensuring the smooth progress of the bending work.
[0029] In this embodiment, the spacer strip to be bent is placed between the two positioning rods 2 and the pusher 5. The pusher 5 can be selected at different angles depending on the actual bending angle required. During the rotation of the screw 404 driven by the motor in the fixed rod 401, the first pusher 402 slides under the limiting action of the fixed rod 401. The first pusher 402 drives the screw tube 406 to slide synchronously. Under the limiting action of the key block 407 and the keyway 405, the screw tube 406 rotates synchronously with the screw 404. Therefore, under the limiting action of the first pusher 402, the second pusher 403 slides in the first pusher 402, causing the pusher 5, which is engaged with the second pusher 403 at a specific angle, to move towards the two sets of positioning rods 2. Simultaneously, the motor drives the lead screw 304 in the base 1 to rotate. Under the limiting action of the base 1, the connecting frame 315 drives the two sets of first racks 303 to slide synchronously in the base 1. This, combined with the two sets of first gears 302, causes the two sets of mounting shafts 301 to drive the two sets of... The positioning rod 2 and the spacer strip fixed on the positioning rod 2 are bent synchronously. During this process, the angle sensor 305 monitors the rotation angle of the two sets of mounting shafts 301 in real time. With the pusher 5 pressing the spacer strip, the bending process of the spacer strip at different angles is completed. When the handle 311 on the positioning rod 2 is rotated, it drives the second gear 310 to rotate. With the help of the two sets of second racks 309, the two sets of slides 306 are pushed outward synchronously. This drives the two sets of clamps 307 to slide outward synchronously away from the corresponding positioning rod 2. At this time, spacer strips of different models can be placed between the clamps 307 and the positioning rod 2. After releasing the handle 311, the spacer strip is fixed between the clamps 307 and the positioning rod 2 under the action of the torsion spring 312, the first spring 308 and the second spring 314. This fixing method will not damage the spacer strip and allows the spacer strip to slide on the positioning rod 2 during the bending process, ensuring the smooth progress of the bending work.
