[0054] The following further elaborates on this application Figure 1-12 in conjunction with the accompanying drawings.

[0055] The embodiment of this application discloses a processing device for hinges and its forming process.

[0056] Refer to Figure 1 , the processing device includes a first punching machine 1, a second punching machine 2, a first forming die 11 and a second forming die 21. The first forming die 11 is installed on the first punching machine 1, and the second forming die 21 is installed on the second punching machine 2. The hinge is stamped and formed through the first forming die 11 and the second forming die 21.

[0057] Refer to Figure 1 and Figure 2 , both the first punching machine 1 and the second punching machine 2 have a punching seat 3 and a punching head 4. The punching head 4 is located above the punching seat 3, and the punching head 4 is driven by a hydraulic cylinder to move downward in a direction close to or away from the punching seat 3.

[0058] Refer to Figure 3 , the first forming die 11 includes a first lower die 12, a first upper die 13, a punching component 14 and a pre-bending component 15. The workpiece completes steps such as blanking, punching, and pre-bending on the first forming die 11.

[0059] Refer to Figure 3 and Figure 4, the first lower die 12 is fixedly installed on the stamping seat 3 of the first stamping machine 1. The first lower die 12 is provided with a forming groove 121, and the forming groove 121 is formed by die-casting of the first lower die 12. The shape of the forming groove 121 is the same as that of the workpiece; the first upper die 13 is fixedly connected to the stamping head 4. When blanking, the metal sheet is placed on the first lower die 12, and then the first upper die 13 moves in the direction close to the first lower die 12 driven by the stamping head 4, and the first upper die 13 stamps on the first lower die 12. Through the action of the first upper die 13 and the first lower die 12, the metal sheet is punched into the shape of the forming groove 121, and the product in the forming groove 121 is named the workpiece.

[0060] The punching assembly 14 includes a forming stud 141 and a first vertical driving member 142. The forming stud 141 is slidably penetrated through the first lower die 12, and in this embodiment, two forming studs 141 are provided; the first vertical driving member 142 is located at the bottom of the stamping seat 3. The first vertical driving member 142 can be a hydraulic cylinder or a pneumatic cylinder. In this embodiment, the first vertical driving member 142 is a hydraulic cylinder, and the piston rod of the first vertical driving member 142 is fixedly connected to the forming stud 141, so that the first vertical driving member 142 drives the forming stud 141 to move vertically in the forming groove 121.

[0061] In the blanking step, the top of the forming stud 141 is flush with the bottom of the forming groove 121; when punching the workpiece, the first vertical driving member 142 drives the forming stud 141 to move vertically upward in the forming groove 121, so that the forming stud 141 rises, and the forming stud 141 ejects the workpiece from the forming groove 121. Then the first upper die 13 is pressed against the first lower die 12 driven by the stamping head 4, so that the workpiece punches out a through hole through the forming stud 141.

[0062] The punching assembly 14 further includes a forming rib 143 and a second vertical driving member 144. The forming rib 143 is slidably penetrated through the first lower die 12, and in this embodiment, two forming ribs 143 are provided; the second vertical driving member 144 is located at the bottom of the stamping seat 3. The second vertical driving member 144 can be a hydraulic cylinder or a pneumatic cylinder. In this embodiment, the second vertical driving member 144 is a hydraulic cylinder, and the piston rod of the second vertical driving member 144 is fixedly connected to the forming rib 143, so that the second vertical driving member 144 drives the forming rib 143 to move vertically in the forming groove 121.

[0063] When the workpiece is punched with a through hole, the top of the forming rib 143 is flush with the bottom of the forming groove 121; after the through hole is punched in the workpiece, the second vertical driving member 144 drives the forming rib 143 to move vertically upward in the forming groove 121, causing the forming rib 143 to rise. The forming rib 143 ejects the workpiece from the forming groove 121, and then the first upper die 13 is pressed against the first lower die 12 driven by the punching head 4, so that the workpiece punches out the side groove through the forming rib 143.

[0064] See Figure 5 、 Figure 6 and Figure 7 , the pre-bending assembly 15 includes a cushion block 151, a horizontal driving member 152 and a vertical lifting block 153. The cushion block 151 horizontally slides through the first lower die 12; the horizontal driving member 152 is fixedly connected to the punching seat 3. The horizontal driving member 152 can be a hydraulic cylinder or a pneumatic cylinder. In this embodiment, the horizontal driving member 152 is a hydraulic cylinder. The piston rod of the horizontal driving member 152 is fixedly connected to one end of the cushion block 151, and the cushion block 151 is driven by the horizontal driving member 152 to slide on the first lower die 12; the vertical lifting block 153 is located at the bottom of the cushion block 151, and a lifting hydraulic cylinder 154 is arranged at the bottom of the punching seat 3. The piston rod of the lifting hydraulic cylinder 154 is fixedly connected to the vertical lifting block 153, and the vertical lifting block 153 is driven by the lifting hydraulic cylinder 154 to move vertically. The top of the vertical lifting block 153 has a rounded corner.

[0065] When the workpiece is being punched, the top surface of the cushion block 151 is flush with the bottom of the forming groove 121, and the vertical lifting block 153 is located on the top of the cushion block 151; after the workpiece punching is completed, the horizontal driving member 152 drives the cushion block 151 out of the forming groove 121, and then the lifting hydraulic cylinder 154 drives the vertical lifting block 153 to move upward, so that the rounded corner of the vertical lifting block 153 is smoothly connected to the bottom of the forming groove 121. At this time, one end of the workpiece close to the vertical lifting block 153 is lifted, and then the first upper die 13 is pressed against the first lower die 12 driven by the punching head 4, so that the workpiece punches out the bent edge through the vertical lifting block 153.

[0066] See Figure 8 , the second forming die 21 includes a second lower die 22, a second upper die 23, a curling assembly 24 and a bending assembly 25. The workpiece completes steps such as curling and bending on the second forming die 21.

[0067] See Figure 9 and Figure 10, the second lower die 22 is installed on the stamping seat 3 of the second stamping machine 2. The second lower die 22 includes a fixing plate 221, a rotating seat 222 and a rotating cylinder 223. The fixing plate 221 is fixedly connected to the stamping seat 3. The rotating seat 222 is rotatably connected to the stamping seat 3, and there is a distance between the fixing plate 221 and the rotating seat 222, so that a clamping cavity is formed between the fixing plate 221 and the rotating seat 222. The rotating cylinder 223 is located on the side of the rotating seat 222 away from the fixing plate 221. One end of the rotating cylinder 223 is hinged to the stamping seat 3, and the other end is hinged to the rotating seat 222. Moreover, the rotating seat 222 has a rotating edge, and the rotating seat 222 is hinged to the stamping seat 3 through the rotating edge.

[0068] When the workpiece is curled, the workpiece completed by the first forming die 11 is clamped between the fixing plate 221 and the rotating seat 222. The workpiece is clamped by the second lower die 22, and then the second upper die 23 punches on the bent edge to curl the workpiece. Among them, when the second lower die 22 clamps the workpiece, the rotating cylinder 223 drives the rotating seat 222 to rotate away from the fixing plate 221 along the rotating edge, so that the clamping cavity expands. After the workpiece is placed in the clamping cavity, the rotating cylinder 223 drives the rotating seat 222 to rotate towards the fixing plate 221, so that the rotating seat 222 and the fixing plate 221 clamp the workpiece.

[0069] See Figure 10 , Figure 11 and Figure 12 , the curling assembly 24 includes a first clamping rod 241, a second clamping rod 242 and a curling rod 243. The curling rod 243 is located between the first clamping rod 241 and the second clamping rod 242, and one end of the curling rod 243 is fixedly connected to the first clamping rod 241, and the other end is connected to the second clamping rod 242. When the workpiece is curled, the curling rod 243 is abutted against the workpiece. When the second upper die 23 punches on the bent edge, the bent edge of the workpiece is curled on the curling rod 243, making the curling of the workpiece more complete.

[0070] To facilitate the workpiece to slide out from the curling rod 243, the curling rod 243 is inserted into the second clamping rod 242. A fixing block 244 is provided at the end of the second clamping rod 242, and the fixing block 244 is provided with an insertion hole 245 for the curling rod 243 to be inserted.

[0071] The top surface of the rotating seat 222 is provided with a first bending groove 224, and the workpiece after curling is bent through the first bending groove 224. To enable the workpiece after curling to enter the bending step, a first telescopic cylinder 31 and a second telescopic cylinder 32 are arranged on the punching seat 3 of the second punching machine 2. The first clamping rod 241 is connected to the piston rod of the first telescopic cylinder 31, and the second clamping rod 242 is connected to the piston rod of the second telescopic cylinder 32. The first telescopic cylinder 31 and the second telescopic cylinder 32 drive the first clamping rod 241 and the second clamping rod 242 to move, thereby moving the workpiece. When the workpiece is located behind the first bending groove 224, the punching head 4 of the second punching machine 2 drives the second upper die 23 to move downward, so that the second upper die 23 bends the workpiece.

[0072] The rotating seat 222 is further provided with a second bending groove 26. After the workpiece is bent through the first bending groove 224, the workpiece is placed in the second bending groove 26, and the workpiece is further bent through the second bending groove 26.

[0073] To enable the workpiece to enter the second bending groove 26, the punching seat 3 is provided with a moving component 27. The moving component 27 includes a moving seat 271, a rotating motor 272 and a rotating lead screw 273. The moving seat 271 is provided with a sliding groove 274. The rotating motor 272 is fixedly connected to one end of the moving seat 271. The rotating lead screw 273 is located in the sliding groove 274. Both ends of the rotating lead screw 273 are rotatably connected to the moving seat 271, and one end of the rotating lead screw 273 is fixedly connected to the output shaft of the rotating motor 272, so that the rotating motor 272 drives the rotating lead screw 273 to rotate.

[0074] The first telescopic cylinder 31 is located in the sliding groove 274. The first telescopic cylinder 31 is sleeved on the rotating lead screw 273, and the first telescopic cylinder 31 is threadedly connected to the rotating lead screw 273. When the rotating motor 272 drives the rotating lead screw 273 to rotate, the first telescopic cylinder 31 moves along the length direction of the rotating lead screw 273 in the sliding groove 274.

[0075] To enable the first telescopic cylinder 31 to move more smoothly in the sliding groove 274, two parallel guide rods 275 are arranged in the sliding groove 274 of the moving seat 271. Both guide rods 275 are slidably inserted into the first telescopic cylinder 31. Through the guiding action of the two guide rods 275, the first telescopic cylinder 31 moves more stably in the sliding groove 274.

[0076] The second telescopic cylinder 32 is also located within the sliding groove 274 and is also slidably sleeved on the rotating lead screw 273, enabling the second telescopic cylinder 32 to also slide within the sliding groove 274. The difference between the second telescopic cylinder 32 and the first telescopic cylinder 31 is that the first telescopic cylinder 31 is threadedly connected to the rotating lead screw 273, while the second telescopic cylinder 32 is merely sleeved on the rotating lead screw 273. The hole in the second telescopic cylinder 32 through which the rotating lead screw 273 passes is larger than the diameter of the rotating lead screw 273, meaning that when the rotating lead screw 273 rotates, it does not drive the second telescopic cylinder 32 to move.

[0077] The moving seat 271 is provided with a partition plate 276 at the middle of the sliding groove 274. The rotating lead screw 273 rotates and passes through the partition plate 276, and the two guide rods 275 are fixedly passed through the partition plate 276. The first telescopic cylinder 31 and the second telescopic cylinder 32 are respectively located on the two sides of the partition plate 276, such that the partition plate 276 separates the first telescopic cylinder 31 and the second telescopic cylinder 32.

[0078] To make it easier for the curling rod 243 to be inserted into the second clamping rod 242, a compression spring 277 is sleeved on the rotating lead screw 273. One end of the compression spring 277 abuts against the second telescopic cylinder 32, and the other end abuts against the groove wall of the sliding groove 274. Through the action of the compression spring 277, the second telescopic cylinder 32 has a tendency to always move closer to the first telescopic cylinder 31.

[0080] Step S1: Install and debug the first forming die 11;

[0081] Step S2: The manipulator places the metal plate above the first forming die 11, and the metal plate abuts against the first forming die 11. When the sensor detects the metal plate, the blanking punch 4 of the stamping machine punches on the metal plate;

[0082] Step S3: The groove block of the first forming die 11 sinks, and the first upper die 13 punches on the workpiece;

[0083] Step S4: The horizontal driving member 152 drives the forming pad 151 to move outward, the front end of the first forming die 11 is lifted, and the bent end of the workpiece is driven to rise;

[0084] Step S5: The pre-bending punch 4 of the stamping machine punches on the workpiece;

[0085] Step S6: The gripping member moves the workpiece from the first forming die 11 to the second forming die 21. The first forming die 11 clamps the workpiece, and the curling punch 4 of the stamping machine punches the workpiece;

[0086] Step S7: The rounding rod 243 is inserted into the shaft hole, and the circular stamping head 4 of the stamping machine stamps the workpiece;

[0087] Step S8: The rounding rod 243 drives the workpiece to move into the first bending groove 224 of the second forming die 21, and the second upper die 23 stamps the workpiece;

[0088] Step S9: The rounding rod 243 drives the workpiece to move out of the first bending groove 224 and drives the workpiece to move into the second bending groove 26;

[0089] Step S10: The second upper die 23 stamps the workpiece in the second bending groove 26, thereby bending the workpiece.

[0090] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
