Therefore, a full-automatic bending device for precision hardware processing is proposed for the above problems.

When the hardware is bent, the hardware is pressed into the die bracket through the bending bracket to bend the hardware. The bending angle of the hardware is the same as the angle of the die bracket, but the bending angle of the hardware cannot be changed, and the hardware cannot be bent to any angle, so the practicability is relatively low.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0027] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0028] A fully automatic bending device for processing precision hardware parts, as Figures 1-4 shown, includes a housing 100. The top end of the inner wall of the housing 100 is fixedly connected with a cylinder 101. The output end of the cylinder 101 is provided with a bending abutting rod 102. The bottom end of the inner wall of the housing 100 is fixedly connected with a workbench 103. The top of the workbench 103 is provided with a bending mechanism 200;

[0029] The bending mechanism 200 includes a first bracket 201. Two groups of first brackets 201 are fixedly connected to the top end of the workbench 103. Two groups of rotating shafts 202 are rotatably connected to the sides of the two groups of first brackets 201 close to each other. Folding plates 203 are fixedly sleeved on the outer walls of the two groups of rotating shafts 202. The front ends of the two groups of rotating shafts 202 extend to the outside of one group of first brackets 201. First gears 204 are fixedly connected to the front ends of the two groups of rotating shafts 202, and the two groups of first gears 204 mesh with each other. A worm gear 205 is fixedly connected to the outer wall of one group of first gears 204. A second bracket 206 is fixedly connected to the front end of the workbench 103. A motor 207 is fixedly connected to the side wall of the second bracket 206. A worm 208 is fixedly connected to the output end of the motor 207, and the worm 208 meshes with the worm gear 205. A third bracket 209 is fixedly connected to the side wall of the workbench 103, and one end of the worm 208 is rotatably connected to the side wall of the third bracket 209. Fixed seats 210 are fixedly connected to the outer walls of the two groups of folding plates 203 away from each other. Clamping plates 211 are slidably connected to the inner walls of the two groups of fixed seats 210. Lead screws 212 are rotatably connected to the inner walls of the two groups of fixed seats 210, and the inner walls of the two groups of clamping plates 211 are respectively threadedly connected to the outer walls of the two groups of lead screws 212. Rotating handles 213 are fixedly connected to the tops of the two groups of lead screws 212, and the tops of the two groups of rotating handles 213 respectively extend above the two groups of fixed seats 210. Chute grooves 214 are formed in the outer walls of the two groups of fixed seats 210. Sliders 215 are fixedly connected to the outer walls of the two groups of clamping plates 211 away from each other, and the outer walls of the two groups of sliders 215 are respectively slidably connected to the inner walls of the two groups of chute grooves 214. Limit blocks 216 are fixedly connected to the outer walls of the two groups of sliders 215 away from each other, and the two groups of limit blocks 216 are respectively slidably connected to the outer walls of the two groups of fixed seats 210.

[0030] When it is necessary to bend the hardware, just place the hardware on the two folding plates 203, place the two ends of the hardware under the two clamping plates 211 respectively, and then rotate the rotating handle 213 to drive the lead screw 212 to rotate. The lead screw 212 can drive the clamping plate 211 to move downward to clamp the two ends of the hardware. The arrangement of the slider 215 and the limit block 216 improves the stability of the clamping plate 211 during movement. After the two ends of the hardware are clamped, start the cylinder 101 to drive the bending abutting rod 102 to move downward to press the bending part of the hardware, and then start the motor 207 to drive the worm 208 to rotate. The worm 208 drives the worm gear 205 to rotate. The worm gear 205 can drive the right first gear 204 to rotate. The right first gear 204 can drive the left first gear 204 to rotate in the opposite direction, so that the two folding plates 203 fold upward simultaneously to bend the hardware. The arrangement of the worm gear 205 and the worm 208 improves the torque of the folding plate 203 during rotation.

[0031] Please refer specifically to Figure 1, a protective door 104 is hinged to the outer wall of the housing 100, and a door lock is provided on the outer wall of the protective door 104.

[0032] The setting of the protective door 104 can prevent the hardware from breaking and flying out during bending, thereby improving the safety of the device.

[0033] Please refer specifically to Figure 1 , a through hole is opened on the outer wall of the protective door 104, and a viewing window 105 is fixedly connected to the inner wall of the through hole.

[0034] The viewing window 105 is made of tempered glass, and the bending state of the hardware inside the housing 100 can be observed through the viewing window 105.

[0035] Please refer specifically to Figure 5 , a replacement mechanism 300 is provided at the top of the bending abutting rod 102. The replacement mechanism 300 includes a mounting seat 301. The top of the bending abutting rod 102 is fixedly connected to the mounting seat 301. The outer wall of the output end of the cylinder 101 is slidably connected to the inner wall of the mounting seat 301. Two sets of sliding grooves are opened on the inner wall of the mounting seat 301, and two sets of clamping blocks 302 are slidably connected to the inner walls of the two sets of sliding grooves. The outer walls of the two sets of clamping blocks 302 facing away from each other are fixedly connected with limiting springs, and the two ends of the two springs facing away from each other are respectively fixedly connected to the inner walls of the two sets of sliding grooves. Two sets of clamping grooves are opened on the outer wall of the output end of the cylinder 101, and the two sets of clamping grooves are respectively fitted with the two sets of clamping blocks 302. Two sets of sliding grooves are opened on the outer wall of the mounting seat 301, and two sets of push rods 304 are slidably connected to the inner walls of the two sets of sliding grooves. Two sets of second gears 303 are rotatably connected to the inner wall of the mounting seat 301. The top of the push rod 304 and the bottom of the clamping block 302 are both fixedly connected with racks 305, and the two sets of racks 305 are both engaged with the second gears 303.

[0036] When the bending abutting rod 102 is damaged and needs to be replaced, only need to push the two push rods 304 towards each other at the same time. The two push rods 304 drive the two second gears 303 to rotate through the two racks 305 below. The rotation of the two second gears 303 can drive the two clamping blocks 302 to move away from each other through the two racks 305 above, so that the clamping blocks 302 are separated from the clamping grooves. At this time, the mounting seat 301 can be separated from the output end of the cylinder 101, thus completing the disassembly. When installing the bending abutting rod 102, only need to insert the mounting seat 301 into the output end of the cylinder 101. The output end of the cylinder 101 can squeeze the clamping block 302 into the sliding groove 214 through the inclined surface of the clamping block 302. When the clamping block 302 moves to the position of the clamping groove, the limiting spring can push the clamping block 302 to reset into the clamping groove. At this time, the installation of the bending abutting rod 102 is completed.

[0037] When in use, when it is necessary to bend the hardware, only need to use the clamping plate 211 to clamp both ends of the hardware, start the cylinder 101 to push the bending abutting rod 102 to move downward to abut against the bending part of the hardware. At this time, start the motor 207 to drive the two folding plates 203 to approach each other to bend the hardware. The folding angle of the two folding plates 203 can be set according to the number of turns of the worm 208, and the hardware can be bent to different angles, with high practicability. The parts not involved in this device are the same as the prior art or can be implemented by using the prior art.
