Description

Technical Field

[0001] The present invention relates to the technical field of bending forming, and particularly relates to a forming device for a bearing mesh. Background Art

[0002] A bearing mesh is a container used for sintering and forming components such as silver, electronic ceramic components, and ceramic resistor components. It has strong high-temperature resistance and will not cause the components to adhere to the container during the sintering process, thereby improving the quality of the sintered products. The bearing mesh is usually cut from a whole sheet of mesh, and then the cut mesh is folded and bent on four sides, and then the bent parts are compacted. The forming process of the bearing mesh can be carried out manually or by special equipment. The traditional bearing mesh forming equipment first cuts the original mesh, and then folds each side in turn, and the forming efficiency is very low, greatly affecting the production efficiency. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: a forming device for a bearing mesh, including a main body device for cutting a whole bearing mesh into a specified length. The main body device includes a pushing frame, and an upper bending device and a lower bending device for bending and forming the four sides of the bearing mesh are arranged on the main body device. The upper bending device includes side columns, and the side columns are fixedly installed on the side of the pushing frame. The lower bending device includes a receiving plate, and the receiving plate is fixedly installed with the pushing frame;

[0004] The main body device includes a moving frame, on which a lower pressing triangular block, a jacking triangular block, and a lower pressing arc plate are fixedly installed. The moving frame is slidably installed with the side columns, and a lower gear is rotatably installed on the moving frame, and an upper gear is fixedly installed on the lower gear;

[0005] The upper bending device includes a top seat, on which a lifting frame is slidably installed. An inner slope is arranged in the lifting frame, and a lower pressing spring is arranged between the lifting frame and the top seat.

[0006] Further, the main body device further includes a sliding rail fixedly installed on the pushing frame. A vertical rod is arranged beside the pushing frame, and an electric cylinder is fixedly installed on the vertical rod. The vertical rod is fixedly installed with the top seat. The lower pressing triangular block is slidably installed with the inner slope, and the moving frame is fixedly installed with the output end of the electric cylinder. The moving frame is slidably installed with the sliding rail.

[0007] Further, a cutting knife is slidably installed on the pushing frame. Lower pressing side blocks are fixedly installed on both sides of the cutting knife. The lower pressing side blocks cooperate with the lower pressing arc plate, and a cutting knife spring is arranged between the lower pressing side blocks and the pushing frame.

[0008] In use, first place the firing tray on the pushing frame, and push the firing tray towards the vertical rod until the firing tray reaches the end of the pushing frame. In the initial state, the pressing arc plate is located outside the pressing side block, the cutting knife is in the raised state, the electric cylinder contracts, driving the pressing arc plate to retract. The pressing arc plate presses down the pressing side block and the cutting knife, compressing the cutting knife spring. The cutting knife cuts the firing tray, and at the same time, the moving frame retracts, driving the cutting knife to retract. The pressing spring that was originally in the stretched state rebounds, causing the lifting frame to rise.

[0009] Furthermore, the upper bending device further includes four side columns fixedly installed on the top seat. A fixed column is fixedly installed on the top seat. A pressing plate is fixedly installed below the lifting frame. Four track plates are fixedly installed on the pressing plate. A rotating frame is slidably installed on the track plates. A docking gear is fixedly installed on the rotating frame. The rotating frame rotates around the fixed column and can slide up and down along the fixed column. A magnet is fixedly installed at the bottom of the pressing plate. A top motor is fixedly installed on the top seat. A motor gear is fixedly installed on the motor shaft of the top motor.

[0010] Furthermore, four corner lifting columns are slidably installed on the pushing frame. A corner cutting knife is fixedly installed below the corner lifting columns. A cutting knife holder is fixedly installed on the corner lifting columns. The cutting knife holder is slidably installed with the lifting frame. A pressing frame is fixedly installed below the cutting knife holder. Four extending frames are fixedly installed on the lifting frame. Long grooves are provided on the extending frames. A rotating rod is rotatably installed on the side column. Long grooves are provided on the corner lifting columns. The rotating rod is rotatably installed with the long grooves on the extending frames and the long grooves on the corner lifting columns.

[0011] Furthermore, a side pressing plate is slidably installed on the track plate. The side pressing plate is provided with a rounded corner. A pressing plate spring is provided between the side pressing plate and the track plate. A rotating rod is rotatably installed on the rotating frame. The rotating rod is rotatably installed with the side pressing plate.

[0012] When the lifting frame rises, it drives the extending frame to rise, thereby driving the rotating rod to rotate, which in turn drives the four-corner lifting columns, the cutter frame, the four-corner cutters, and the pressing frame to descend. The four-corner cutters first contact the four corners of the bearing mesh, and the four corners of the bearing mesh are cut off by the four-corner cutters. Subsequently, the moving frame continues to retract, and the lifting frame continues to descend. The pressing frame contacts the bearing mesh. At this time, the triangular block is lifted, which in turn lifts the docking slope block. The four sides of the bearing mesh are erected by the mesh-lifting plate. Subsequently, the electric cylinder starts to extend, thereby driving the lifting frame to start descending by pressing down the triangular block. The compression spring is stretched. The descending of the lifting frame drives the pressing frame, the four-corner lifting columns, and the four-corner cutters to rise. The lifting frame drives the rotating frame, the docking gear, and the pressing plate to descend. The upper surface of the bearing mesh is pressed tightly by the pressing plate. And when the electric cylinder extends to its maximum length, the upper gear meshes with the motor gear, and the lower gear meshes with the docking gear. The top motor drives the motor gear to rotate, which in turn drives the upper gear and the lower gear to rotate, thereby driving the docking gear and the rotating frame to rotate. The side pressing plates slide inward through the rotating rod, and the pressing plate springs are compressed. The four erected sides of the bearing mesh are pressed flat inward by the four side pressing plates, realizing the bending and forming of the four sides of the bearing mesh to form the product. Subsequently, the electric cylinder starts to contract, and the compression spring starts to drive the lifting frame and the pressing plate to rise. The formed product is adsorbed by the magnet at the bottom of the pressing plate and rises together with the formed product. At this time, the subsequent bearing mesh is continuously pushed forward to the end of the pushing-in frame for the next processing, and so on.

[0013] Further, the lower bending device includes four push sliders slidably mounted on the receiving plate. Side push plates are fixedly mounted on the push sliders. Four mesh-lifting plates are rotatably mounted on the receiving plate, and lifting plates are fixedly mounted on the mesh-lifting plates.

[0014] Further, a lifting link is rotatably mounted on the push slider, a docking slope block is rotatably mounted on the lifting link, a lower spring is provided between the docking slope block and the receiving plate. The bottom of the docking slope block is a slope surface, and the docking slope block cooperates with the jacking triangular block.

[0015] After the jacking triangular block contacts the docking slope block, the moving frame continues to retract. The jacking triangular block drives the docking slope block to rise, the lower spring is compressed. The docking slope block drives the four lifting links to rotate, thereby driving the push sliders and the side push plates to slide outward. After the side push plates contact the lifting plates, the mesh-lifting plates are pushed to rotate through the lifting plates. The mesh-lifting plates rotate ninety degrees to erect the four sides of the cut-off bearing mesh.

[0016] The beneficial effects of the present invention compared with the prior art are as follows: (1) The main device provided by the present invention can automatically cut the whole sintering mesh into a specified size, and during the telescopic movement of the electric cylinder, it can automatically realize the cutting, four-corner cutting, four-side bending, four-side pressing and discharging actions of the sintering mesh, with high automation and good continuity; (2) When the lifting frame provided by the present invention descends, it first cuts the four corners of the cut sintering mesh, and then drives the four mesh-lifting plates to turn upwards. When turning, the upper surface of the sintering mesh is pressed by the pressing frame, thereby ensuring the stability of the sintering mesh during the process of standing up the edges; (3) When the rotating frame provided by the present invention rotates, it drives the four side pressing plates to move inwards synchronously, realizing the pressing down and forming of the four erected flanges. At the same time, during this process, the upper surface of the sintering mesh is pressed by the pressing plate to improve the forming effect; (4) After the pressing plate and the side pressing plate cooperate to form the sintering mesh, when the lifting frame rises next time, the formed sintering mesh is lifted by the magnet. At this time, the unprocessed whole sintering mesh can be pushed forward continuously, and the sintering mesh adsorbed by the magnet can be taken off to realize continuous processing.

[0032] As Figure 2 shown, a cutting knife 111 is slidably installed on the pushing frame 101. Two downward pressing side blocks 112 are fixedly installed on both sides of the cutting knife 111. The downward pressing side blocks 112 cooperate with the downward pressing arc plate 107, and a cutting knife spring 113 is arranged between the downward pressing side blocks 112 and the pushing frame 101.

[0033] During use, first place the firing support net 4 on the pushing frame 101, and push the firing support net 4 towards the direction of the vertical rod 103 until the firing support net 4 abuts against the end of the pushing frame 101. In the initial state, the downward pressing arc plate 107 is located outside the downward pressing side block 112, and the cutting knife 111 is in the lifted state. The electric cylinder 104 contracts, driving the downward pressing arc plate 107 to retract. The downward pressing arc plate 107 presses down the downward pressing side block 112 and the cutting knife 111, and the cutting knife spring 113 is compressed. The firing support net 4 is cut by the cutting knife 111. At the same time, the moving frame 105 retracts, driving the cutting knife 111 to retract, and the downward pressing spring 221 in the original stretched state rebounds, causing the lifting frame 212 to rise.

[0034] As Figures 3 - 7 shown, the upper bending device further includes four side columns 208 fixedly installed on the top seat 202. A fixed column 207 is fixedly installed on the top seat 202. A pressing plate 218 is fixedly installed below the lifting frame 212. Four track plates 216 are fixedly installed on the pressing plate 218. A rotating frame 205 is slidably installed on the track plates 216. A docking gear 206 is fixedly installed on the rotating frame 205. The rotating frame 205 rotates around the fixed column 207, and the rotating frame 205 can slide up and down along the fixed column 207. A magnet 219 is fixedly installed at the bottom of the pressing plate 218, and a top motor 203 is fixedly installed on the top seat 202. A motor gear 204 is fixedly installed on the motor shaft of the top motor 203.

[0035] As Figures 3 - 7As shown, four corner lifting columns 210 are slidably mounted on the pushing frame 101. A corner cutter 211 is fixedly mounted below the corner lifting columns 210. A cutter holder 214 is fixedly mounted on the corner lifting columns 210. The cutter holder 214 is slidably mounted with the lifting frame 212. A pressing frame 220 is fixedly mounted below the cutter holder 214. Four extending frames 213 are fixedly mounted on the lifting frame 212. Long grooves are provided on the extending frames 213. A rotating rod 209 is rotatably mounted on the side column 208. Long grooves are provided on the corner lifting columns 210. The rotating rod 209 is rotatably mounted with the long grooves on the extending frames 213 and the rotating rod 209 is rotatably mounted with the long grooves on the corner lifting columns 210.

[0036] As Figures 3 - 7 shown, a side pressing plate 215 is slidably mounted on the track plate 216. The side pressing plate 215 is provided with rounded corners. A pressing plate spring 217 is provided between the side pressing plate 215 and the track plate 216. A rotating rod 223 is rotatably mounted on the rotating frame 205. The rotating rod 223 is rotatably mounted with the side pressing plate 215.

[0037] When the lifting frame 212 rises, it drives the extending frame 213 to rise, thereby driving the rotating rod 209 to rotate, and then driving the four-corner lifting columns 210, the cutter frame 214, the four-corner cutters 211, and the pressing frame 220 to descend. The four-corner cutters 211 first contact the four corners of the bearing net 4, and the four corners of the bearing net 4 are cut off by the four-corner cutters 211. Subsequently, the moving frame 105 continues to retract, and the lifting frame 212 continues to descend. The pressing frame 220 contacts the bearing net 4. At this time, the top triangular block 106 is lifted to lift the docking slope block 307, and the four sides of the bearing net 4 are erected by the net-lifting plate 305. Subsequently, the electric cylinder 104 starts to extend, so as to drive the lifting frame 212 to start descending by pressing down the triangular block 110. The pressing spring 221 is stretched. The descent of the lifting frame 212 drives the pressing frame 220, the four-corner lifting columns 210, and the four-corner cutters 211 to rise. The lifting frame 212 drives the rotating frame 205, the docking gear 206, and the pressing plate 218 to descend. The upper surface of the bearing net 4 is pressed tightly by the pressing plate 218. And when the electric cylinder 104 extends to the longest, the upper gear 109 meshes with the motor gear 204, and the lower gear 108 meshes with the docking gear 206. The top motor 203 drives the motor gear 204 to rotate, thereby driving the upper gear 109 and the lower gear 108 to rotate, and then driving the docking gear 206 and the rotating frame 205 to rotate. The side pressing plates 215 are driven to slide inwards by the rotating rod 223, and the pressing plate springs 217 are compressed. The four erected sides of the bearing net 4 are pressed flat inwards by the four side pressing plates 215, realizing the bending and forming of the four sides of the bearing net 4 to form the product. Subsequently, the electric cylinder 104 starts to contract, and the pressing spring 221 starts to drive the lifting frame 212 and the pressing plate 218 to rise. The formed product is adsorbed by the magnet 219 at the bottom of the pressing plate 218 and rises together with the formed product. At this time, the subsequent bearing net 4 is continuously pushed forward to the end of the pushing-in frame 101 for the next processing, and so on.

[0038] As Figure 8 , Figure 9 shown, the lower bending device includes four push sliders 302 slidably installed on the receiving plate 301. Side push plates 303 are fixedly installed on the push sliders 302. Four net-lifting plates 305 are rotatably installed on the receiving plate 301. Lifting plates 304 are fixedly installed on the net-lifting plates 305.

[0039] As Figure 8 , Figure 9 shown, a lifting link 306 is rotatably installed on the push slider 302. A docking slope block 307 is rotatably installed on the lifting link 306. A lower spring 308 is arranged between the docking slope block 307 and the receiving plate 301. The bottom of the docking slope block 307 is a slope surface, and the docking slope block 307 cooperates with the top triangular block 106.

[0040] After the jacking triangular block 106 contacts the docking slope block 307, the moving frame 105 continues to retract. The jacking triangular block 106 drives the docking slope block 307 to rise, the lower spring 308 is compressed, and the docking slope block 307 drives the four lifting link rods 306 to rotate, thereby driving the push slider 302 and the side push plate 303 to slide outwards. After the side push plate 303 contacts the lifting plate 304, the lifting plate 304 is used to push the net-lifting plate 305 to rotate. The net-lifting plate 305 rotates 90 degrees to erect the four sides of the cut bearing net 4.

[0041] The working principle of a forming device for a firing mesh disclosed in the present invention is as follows: When in use, first place the firing mesh 4 on the pushing frame 101, and push the firing mesh 4 towards the vertical rod 103 until the firing mesh 4 abuts against the end of the pushing frame 101. In the initial state, the downward pressing arc plate 107 is located outside the downward pressing side block 112, the cutting knife 111 is in the raised state, the electric cylinder 104 contracts, driving the downward pressing arc plate 107 to retract. The downward pressing arc plate 107 presses down the downward pressing side block 112 and the cutting knife 111, and the cutting knife spring 113 is compressed. The firing mesh 4 is cut by the cutting knife 111. At the same time, the moving frame 105 retracts, driving the cutting knife 111 to retract, and the downward pressing spring 221 that was originally in a stretched state rebounds, causing the lifting frame 212 to rise. When the lifting frame 212 rises, it drives the extending frame 213 to rise, thereby driving the rotating rod 209 to rotate, and then driving the four-corner lifting columns 210, the cutting knife frame 214, the four-corner cutting knives 211, and the pressing frame 220 to descend. The four-corner cutting knives 211 first contact the four corners of the firing mesh 4, and the four corners of the firing mesh 4 are cut off by the four-corner cutting knives 211. Subsequently, the moving frame 105 continues to retract, and the lifting frame 212 continues to descend. The pressing frame 220 contacts the firing mesh 4. When the top-up triangular block 106 contacts the docking slope block 307, the moving frame 105 continues to retract, and the top-up triangular block 106 drives the docking slope block 307 to rise. The lower spring 308 is compressed, and the docking slope block 307 drives the four lifting link rods 306 to rotate, thereby driving the push slider 302 and the side push plate 303 to slide outwards. After the side push plate 303 contacts the lifting plate 304, the lifting plate 304 is pushed to drive the net-lifting plate 305 to rotate. The net-lifting plate 305 rotates by ninety degrees to erect the four sides of the cut-off firing mesh 4. Subsequently, the electric cylinder 104 starts to extend, thereby driving the lifting frame 212 to start descending through the downward pressing triangular block 110. The downward pressing spring 221 is stretched. The descent of the lifting frame 212 drives the pressing frame 220, the four-corner lifting columns 210, and the four-corner cutting knives 211 to rise. The lifting frame 212 drives the rotating frame 205, the docking gear 206, and the pressing plate 218 to descend. The upper surface of the firing mesh 4 is pressed tightly by the pressing plate 218. And when the electric cylinder 104 extends to the longest, the upper gear 109 meshes with the motor gear 204, and the lower gear 108 meshes with the docking gear 206. The top motor 203 drives the motor gear 204 to rotate, thereby driving the upper gear 109 and the lower gear 108 to rotate, and then driving the docking gear 206 and the rotating frame 205 to rotate. The side pressing plates 215 slide inwards through the rotating rod 223, and the pressing plate spring 217 is compressed. The four erected sides of the firing mesh 4 are pressed flat inwards by the four side pressing plates 215 to form the product by bending the four sides of the firing mesh 4. Subsequently, the electric cylinder 104 starts to contract, and the downward pressing spring 221 starts to drive the lifting frame 212 and the pressing plate 218 to rise. The formed product is adsorbed by the magnet 219 at the bottom of the pressing plate 218 and rises together with the formed product. At this time, the subsequent firing mesh 4 is continuously pushed forward to the end of the pushing frame 101 for the next processing, and so on.

Any person skilled in the art within the technical scope of the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
