Description

Technical Field

[0001] The present invention relates to the technical field of stamping processing, and particularly relates to a telescopic and rotating scaffolding connecting piece and a production device thereof. Background Art

[0002] A scaffolding is a working platform used for construction erection. It can be divided into external and internal types according to the erection position, into wooden, bamboo, steel, etc. according to different materials, and into vertical pole type, bridge type, portal type, etc. according to different functions; with the continuous development of the construction industry, the word 'efficient' has become a key term in construction, and the loading and unloading method of the scaffolding has also changed. From the initial connection of each pipe and each piece, to the folding type, and then to the quick installation and disassembly method, the work efficiency has been greatly increased. In ordinary construction operations, most of the scaffolding connecting pieces are made of steel. The scaffolding connecting pieces in the prior art usually need to be processed in multiple processes, involving re-transfer and transfer of loading and unloading, with cumbersome operations, low automation degree, and poor continuity. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: A production device for a telescopic and rotating scaffolding connecting piece, including a conveying mechanism for conveying a steel plate. The conveying mechanism includes a processing box, and a blanking mechanism for punching and blanking the steel plate and a stamping mechanism for stamping and forming are arranged on the conveying mechanism; The blanking mechanism includes a punching seat and a punching head slidably installed in the processing box. A transmission wheel is rotatably installed on the processing box. A pushing module is arranged in the punching head, a clamping module is arranged in the punching seat, an energy storage spring is arranged between the punching seat and the processing box, and three punching heads are fixedly installed below the punching seat.

[0004] Further, the conveying mechanism includes a horizontal shaft rotatably installed on the processing box. The transmission wheel drives the horizontal shaft to rotate through belt transmission. Two front conveying wheels are rotatably installed on the processing box, and a front conveyor belt is wound around the two front conveying wheels. Two rear conveying wheels are rotatably installed on the processing box, and a rear conveyor belt is wound around the two rear conveying wheels. The horizontal shaft drives the front conveying wheels and the rear conveying wheels to rotate through gear transmission.

[0005] During use, the steel plate is inserted between the front conveyor belt and the processing box. The transmission wheel drives the horizontal shaft to rotate through belt transmission. The horizontal shaft drives the front conveying wheels and the rear conveying wheels to rotate through gear transmission. The front conveying wheels drive the front conveyor belt to rotate, and the steel plate is pushed into the processing box through the front conveyor belt. Each time the transmission wheel rotates once, the steel plate advances one station. The rear conveying wheels drive the rear conveyor belt to rotate and send out the used steel plate.

[0006] Further, the blanking mechanism further includes a punching gear and a blanking gear rotatably mounted on the processing box. A punching column is fixedly mounted below the punching gear. A punching bidirectional screw is slidably mounted on the punching column. The punching bidirectional screw is provided with external threads on both sides. A punching convex ball is provided on the processing box. The punching convex ball slides in the external threads on both sides of the punching bidirectional screw. A blanking column is fixedly mounted below the blanking gear. A blanking bidirectional screw is slidably mounted on the blanking column. A blanking convex ball is provided on the processing box. The blanking convex ball slides in the external threads on both sides of the blanking bidirectional screw. A reset spring is provided between the punching seat and the processing box.

[0007] Further, the clamping module includes a chuck fixedly mounted below the punching bidirectional screw. A clamping groove is provided on the punching seat. Two clamping blocks are slidably mounted on the punching seat. The clamping blocks are provided with slopes. A clamping block spring is provided between the clamping blocks and the punching seat. A pushing ring is provided inside the processing box.

[0008] Further, the pushing module includes a guide post slidably mounted inside the blanking head. A pushing plate is fixedly mounted on the guide post. A pushing spring is provided between the pushing plate and the blanking head. The blanking bidirectional screw is rotatably mounted with the blanking head.

[0009] Further, a motor is fixedly mounted on the processing box. A toothless gear, an internal transmission gear, and an external transmission gear are rotatably mounted on the processing box. The motor drives the toothless gear to rotate through a belt drive. The toothless gear meshes with the internal transmission gear. The toothless gear meshes with the external transmission gear. The internal transmission gear drives the punching gear and the blanking gear to rotate through a belt drive. The external transmission gear drives the transmission wheel to rotate through a gear drive.

[0010] The motor drives the toothless gear to rotate through a belt drive. When the toothless gear meshes with the inner transmission gear, the toothless gear disengages from the outer transmission gear. When the toothless gear meshes with the outer transmission gear, the toothless gear disengages from the inner transmission gear. When the outer transmission gear meshes with the toothless gear, it drives the transmission wheel to rotate. When the toothless gear meshes with the inner transmission gear, it drives the punching gear and the blanking gear to rotate through the belt drive. The rotation of the punching gear drives the punching column to rotate, thereby driving the punching double-headed screw to rotate. Under the action of the punching convex ball, it drives the punching double-headed screw and the chuck to descend relative to the punching column. When the chuck descends into the card slot and contacts the slope of the block, it will push the block to slide outwards relative to the card slot, and the block spring is stretched. When the chuck passes through the block, the block spring rebounds, causing the chuck to reach below the block. At this time, the punching double-headed screw and the chuck descend to the lowest point. Since the punching double-headed screw has double threads, when the punching gear continues to rotate, the punching double-headed screw and the chuck start to rise, driving the punching seat to rise. The energy storage spring is compressed and the reset spring is stretched. As the punching seat rises, when the slope of the block contacts the pushing ring, the pushing ring pushes the block to slide outwards, and the block spring is stretched. At this time, the energy storage spring rebounds, driving the punching seat and the punching head to punch downwards, and punching the steel plate below through the punching head.

[0011] Meanwhile, the blanking gear drives the blanking column to rotate, thereby driving the blanking double-headed screw to rotate. Under the action of the blanking convex ball, the blanking double-headed screw descends relative to the blanking column, thereby driving the blanking head to descend. First, the pushing plate contacts the steel plate below it, causing the pushing spring to be compressed. Subsequently, the blanking head contacts the steel plate, and the steel plate is blanked through the blanking head to obtain a blanked part. The blanked part is still located in the steel plate. Since the blanking double-headed screw has double threads, when the blanking head descends to the lowest point, the blanking gear continues to rotate, driving the blanking head to rise. At this time, the pushing spring rebounds, causing the pushing plate to press on the blanked part to prevent the blanked part from being lifted by the blanking head. Subsequently, the blanking head returns to its initial position.

[0012] Furthermore, the stamping mechanism includes an electric cylinder fixedly installed on the processing box. A stamping frame is fixedly installed on the output end of the electric cylinder. A stamping head is slidably installed on the stamping frame. A high-strength spring is provided between the stamping head and the stamping frame. A side stamping head is slidably installed on the stamping head. A side spring is provided between the side stamping head and the stamping frame.

[0013] Furthermore, a lower die is fixedly installed below the processing box. A pushing rod is rotatably installed on the lower die. A torsion spring is provided between the lower die and the torsion spring.

[0014] When the steel plate with the cut piece reaches below the stamping head, the electric cylinder extends, driving the stamping frame to descend. The cut piece is ejected from the steel plate onto the lower die by the stamping head. The ejecting rod is pressed down and the torsion spring is twisted. First, the stamping head forms an arc on the cut piece. When the stamping head moves to the lowest end, the high-strength spring is compressed and the side spring is compressed. The side stamping head flattens both sides of the cut piece to complete the forming operation. The obtained scaffolding connector is located on the lower die. Subsequently, the electric cylinder contracts, driving the stamping frame, stamping head and side stamping head to rise. When the stamping head disengages from the scaffolding connector, the torsion spring rebounds, causing the ejecting rod to rotate and push out the scaffolding connector for automatic discharging.

[0015] The beneficial effects of the present invention compared with the prior art are as follows: (1) The punching mechanism and stamping mechanism provided in the present invention cooperate to realize automatic punching, blanking, stamping and discharging of the scaffolding connector, with high processing efficiency; (2) When the toothless gear provided in the present invention meshes with the outer transmission gear, the steel plate advances once, moving one station each time. The part of the steel plate below the punching head moves below the blanking head, the part of the steel plate below the blanking head moves below the stamping head, and the part of the steel plate below the stamping head moves outside. When the toothless gear meshes with the inner transmission gear, the punching head punches the part of the steel plate below the punching head, the blanking head blanks the part of the steel plate below the blanking head, and the stamping head and side stamping head perform stamping forming on the part of the steel plate below the stamping head, with high automation and good continuity; (3) When the blanking module drives the blanking head to rise, the ejecting spring rebounds and presses on the cut piece through the ejecting plate to prevent the cut piece from being lifted by the blanking head.

Detailed implementation manners

[0029] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0030] Example: Refer to Figures 1 - 12 , a production device for a telescopic and rotatable scaffolding connector, including a conveying mechanism for conveying the steel plate 4, the conveying mechanism includes a processing box 101, and a blanking mechanism for punching and blanking the steel plate 4 and a stamping mechanism for stamping and forming are provided on the conveying mechanism; The blanking mechanism includes a punching seat 215 and a blanking head 211 slidably installed in the processing box 101. A transfer wheel 224 is rotatably installed on the processing box 101. A pushing module is arranged inside the blanking head 211, a clamping module is arranged inside the punching seat 215, an energy storage spring 216 is arranged between the punching seat 215 and the processing box 101, and three punching heads 217 are fixedly installed below the punching seat 215.

[0031] As Figure 2 shown in the figure, the conveying mechanism includes a horizontal shaft 102 rotatably installed on the processing box 101. The transfer wheel 224 drives the horizontal shaft 102 to rotate through belt drive. Two front conveying wheels 103 are rotatably installed on the processing box 101, a front conveyor belt 104 is wound outside the two front conveying wheels 103. Two rear conveying wheels 105 are rotatably installed on the processing box 101, a rear conveyor belt 106 is wound outside the two rear conveying wheels 105, and the horizontal shaft 102 drives the front conveying wheels 103 and the rear conveying wheels 105 to rotate through gear drive.

[0032] During use, the steel plate 4 is inserted between the front conveyor belt 104 and the processing box 101. The transfer wheel 224 drives the horizontal shaft 102 to rotate through belt drive. The horizontal shaft 102 drives the front conveying wheels 103 and the rear conveying wheels 105 to rotate through gear drive. The front conveying wheel 103 drives the front conveyor belt 104 to rotate, and the steel plate 4 is pushed into the processing box 101 through the front conveyor belt 104. Every time the transfer wheel 224 rotates once, the steel plate 4 advances one station. The rear conveying wheel 105 drives the rear conveyor belt 106 to rotate, and the used steel plate 4 is sent out.

[0033] As Figures 3 - 8 shown in the figure, the blanking mechanism further includes a punching gear 203 and a blanking gear 207 rotatably installed on the processing box 101. A punching column 204 is fixedly installed below the punching gear 203. A punching bidirectional screw 205 is slidably installed on the punching column 204. The punching bidirectional screw 205 is provided with a bidirectional external thread. A punching convex ball 206 is arranged on the processing box 101. The punching convex ball 206 slides in the bidirectional external thread of the punching bidirectional screw 205. A blanking column 208 is fixedly installed below the blanking gear 207. A blanking bidirectional screw 209 is slidably installed on the blanking column 208. A blanking convex ball 210 is arranged on the processing box 101. The blanking convex ball 210 slides in the bidirectional external thread of the blanking bidirectional screw 209. A reset spring 218 is arranged between the punching seat 215 and the processing box 101.

[0034] As Figures 3 - 8 shown in the figure, the clamping module includes a chuck 223 fixedly installed below the punching bidirectional screw 205. A card slot 220 is arranged on the punching seat 215. Two clamping blocks 221 are slidably installed on the punching seat 215. The clamping blocks 221 are provided with slopes. A clamping block spring 222 is arranged between the clamping blocks 221 and the punching seat 215. A pushing ring 219 is arranged inside the processing box 101.

[0035] As Figures 3 - 8 shown, the pushing-out module includes a guide post 213 slidably installed in the blanking head 211. A pushing-out plate 212 is fixedly installed on the guide post 213. A pushing-out spring 214 is arranged between the pushing-out plate 212 and the blanking head 211. The blanking bidirectional stud 209 is rotatably installed with the blanking head 211.

[0036] As Figures 3 - 8 shown, a motor 201 is fixedly installed on the processing box 101. A toothless gear 202, an inner transmission gear 225 and an outer transmission gear 226 are rotatably installed on the processing box 101. The motor 201 drives the toothless gear 202 to rotate through a belt drive. The toothless gear 202 meshes with the inner transmission gear 225, and the toothless gear 202 meshes with the outer transmission gear 226. The inner transmission gear 225 drives the punching gear 203 and the blanking gear 207 to rotate through a belt drive. The outer transmission gear 226 drives the transmission wheel 224 to rotate through a gear drive.

[0037] The motor 201 drives the toothless gear 202 to rotate through a belt drive. When the toothless gear 202 meshes with the inner transmission gear 225, the toothless gear 202 is disengaged from the outer transmission gear 226. When the toothless gear 202 meshes with the outer transmission gear 226, the toothless gear 202 is disengaged from the inner transmission gear 225. When the outer transmission gear 226 meshes with the toothless gear 202, it drives the transmission wheel 224 to rotate. When the toothless gear 202 meshes with the inner transmission gear 225, it drives the punching gear 203 and the blanking gear 207 to rotate through a belt drive. The rotation of the punching gear 203 drives the punching post 204 to rotate, thereby driving the punching bidirectional stud 205 to rotate. Under the action of the punching convex ball 206, it drives the punching bidirectional stud 205 and the chuck 223 to descend relative to the punching post 204. When the chuck 223 descends to enter the card slot 220 and contacts the slope surface of the block 221, it will push the block 221 to slide outwards relative to the card slot 220, and the block spring 222 is stretched. When the chuck 223 passes through the block 221, the block spring 222 rebounds, so that the chuck 223 reaches below the block 221. At this time, the punching bidirectional stud 205 and the chuck 223 descend to the lowest point. Since the punching bidirectional stud 205 has a double-thread on it, at this time, the punching gear 203 continues to rotate, and the punching bidirectional stud 205 and the chuck 223 start to rise, driving the punching seat 215 to rise. The energy storage spring 216 is compressed, and the return spring 218 is stretched. As the punching seat 215 rises, when the slope surface of the block 221 contacts the pushing-away ring 219, the pushing-away ring 219 pushes the block 221 to slide outwards, and the block spring 222 is stretched. At this time, the energy storage spring 216 rebounds, driving the punching seat 215 and the punching head 217 to punch downwards, and punching the steel plate 4 below through the punching head 217.

[0038] Meanwhile, the blanking gear 207 drives the blanking column 208 to rotate, thereby driving the blanking bi-directional screw 209 to rotate. Under the action of the blanking convex ball 210, the blanking bi-directional screw 209 descends relative to the blanking column 208, thereby driving the blanking head 211 to descend. First, the pushing plate 212 contacts the steel plate 4 below it, causing the pushing spring 214 to be compressed. Subsequently, the blanking head 211 contacts the steel plate 4, and the steel plate 4 is blanked by the blanking head 211 to obtain the blanked part 5. The blanked part 5 still remains in the steel plate 4. Since the blanking bi-directional screw 209 has a double-thread, when the blanking head 211 descends to the lowest point, the blanking gear 207 continues to rotate, driving the blanking head 211 to rise. At this time, the pushing spring 214 rebounds, causing the pushing plate 212 to press on the blanked part 5 to prevent the blanked part 5 from being lifted by the blanking head 211. Subsequently, the blanking head 211 returns to its initial position.

[0039] As Figures 9 - 11 shown, the stamping mechanism includes an electric cylinder 301 fixedly installed on the processing box 101. A stamping frame 302 is fixedly installed on the output end of the electric cylinder 301. A stamping head 303 is slidably installed on the stamping frame 302. A high-strength spring 304 is provided between the stamping head 303 and the stamping frame 302. A side stamping head 305 is slidably installed on the stamping head 303. A side spring 306 is provided between the side stamping head 305 and the stamping frame 302.

[0040] As Figures 9 - 11 shown, a lower die 307 is fixedly installed below the processing box 101. A pushing rod 308 is rotatably installed on the lower die 307. A torsion spring 309 is provided between the lower die 307 and the torsion spring 309.

[0041] When the steel plate 4 with the blanked part 5 reaches below the stamping head 303, the electric cylinder 301 extends, driving the stamping frame 302 to descend. The blanked part 5 is ejected from the steel plate 4 onto the lower die 307 through the stamping head 303. The pushing rod 308 is pressed down, and the torsion spring 309 is twisted. First, the stamping head 303 forms an arc on the blanked part 5. When the stamping head 303 moves to the lowest end, the high-strength spring 304 is compressed, and the side spring 306 is compressed. The two sides of the blanked part 5 are flattened by the side stamping head 305 to complete the forming operation. The obtained scaffolding connector 6 is located on the lower die 307. Subsequently, the electric cylinder 301 contracts, driving the stamping frame 302, the stamping head 303, and the side stamping head 305 to rise. When the stamping head 303 is separated from the scaffolding connector 6, the torsion spring 309 rebounds, causing the pushing rod 308 to rotate and eject the scaffolding connector 6 for automatic discharging.

[0042] As Figure 12As shown in the figure, for the scaffolding connector produced by a telescopic and rotary scaffolding connector production device, the steel plate 4 is obtained by punching and blanking to get the cut piece 5, and the cut piece 5 is stamped by the stamping head 303, the side stamping head 305 and the lower die 307 to obtain the scaffolding connector 6.

[0043] The working principle of a production device for a telescopic and rotary scaffolding connector disclosed in the present invention is as follows: When in use, a steel plate 4 is inserted between the front conveyor belt 104 and the processing box 101. The motor 201 drives the toothless gear 202 to rotate through belt drive. When the toothless gear 202 meshes with the inner transmission gear 225, the toothless gear 202 disengages from the outer transmission gear 226. When the toothless gear 202 meshes with the outer transmission gear 226, the toothless gear 202 disengages from the inner transmission gear 225. When the outer transmission gear 226 meshes with the toothless gear 202, it drives the transmission wheel 224 to rotate. The transmission wheel 224 drives the cross shaft 102 to rotate through belt drive. The cross shaft 102 drives the front conveyor wheel 103 and the rear conveyor wheel 105 to rotate through gear drive. The front conveyor wheel 103 drives the front conveyor belt 104 to rotate, and pushes the steel plate 4 into the processing box 101 through the front conveyor belt 104. Each time the transmission wheel 224 rotates, the steel plate 4 advances one station. The rear conveyor wheel 105 drives the rear conveyor belt 106 to rotate, and sends out the used steel plate 4. When the toothless gear 202 meshes with the inner transmission gear 225, it drives the punching gear 203 and the blanking gear 207 to rotate through belt drive. The rotation of the punching gear 203 drives the punching column 204 to rotate, thereby driving the punching double screw 205 to rotate. Under the action of the punching convex ball 206, it drives the punching double screw 205 and the chuck 223 to descend relative to the punching column 204. When the chuck 223 descends to enter the card slot 220 and contacts the slope of the card block 221, it will push the card block 221 to slide outwards relative to the card slot 220, and the card block spring 222 is stretched. When the chuck 223 passes through the card block 221, the card block spring 222 rebounds, causing the chuck 223 to reach below the card block 221. At this time, the punching double screw 205 and the chuck 223 descend to the lowest point. Since the punching double screw 205 has a double thread, when the punching gear 203 continues to rotate, the punching double screw 205 and the chuck 223 start to rise, driving the punching seat 215 to rise. The energy storage spring 216 is compressed, and the reset spring 218 is stretched. As the punching seat 215 rises, when the slope of the card block 221 contacts the pushing ring 219, the pushing ring 219 pushes the card block 221 to slide outwards, and the card block spring 222 is stretched. At this time, the energy storage spring 216 rebounds, driving the punching seat 215 and the punching head 217 to punch downwards, and punching the steel plate 4 below through the punching head 217.Meanwhile, the blanking gear 207 drives the blanking column 208 to rotate, thereby driving the blanking two-way screw 209 to rotate. Under the action of the blanking convex ball 210, the blanking two-way screw 209 descends relative to the blanking column 208, thereby driving the blanking head 211 to descend. First, the pushing plate 212 contacts the steel plate 4 below it, causing the pushing spring 214 to be compressed. Subsequently, the blanking head 211 contacts the steel plate 4, and the steel plate 4 is blanked by the blanking head 211 to obtain the blanked part 5. The blanked part 5 still remains in the steel plate 4. Since the blanking two-way screw 209 has double threads, when the blanking head 211 descends to the lowest point, the blanking gear 207 continues to rotate, driving the blanking head 211 to rise. At this time, the pushing spring 214 rebounds, causing the pushing plate 212 to press on the blanked part 5 to prevent the blanked part 5 from being lifted by the blanking head 211. Subsequently, the blanking head 211 returns to its initial position. When the steel plate 4 with the blanked part 5 reaches below the stamping head 303, the electric cylinder 301 extends, driving the stamping frame 302 to descend. The blanked part 5 is ejected from the steel plate 4 onto the lower die 307 by the stamping head 303. The ejecting rod 308 is pressed down, and the torsion spring 309 is twisted. First, the stamping head 303 forms an arc on the blanked part 5. When the stamping head 303 moves to the lowest end, the high-strength spring 304 is compressed, and the side spring 306 is compressed. The side stamping head 305 flattens both sides of the blanked part 5 to complete the forming operation. The obtained scaffolding connector 6 is located on the lower die 307. Subsequently, the electric cylinder 301 contracts, driving the stamping frame 302, the stamping head 303, and the side stamping head 305 to rise. When the stamping head 303 disengages from the scaffolding connector 6, the torsion spring 309 rebounds, causing the ejecting rod 308 to rotate and eject the scaffolding connector 6 for automatic discharging.

[0044] That is, when the toothless gear 202 meshes with the outer transmission gear 226, the steel plate 4 advances once, advancing one station each time. The part of the steel plate 4 below the punching head 217 moves below the blanking head 211, the part of the steel plate 4 below the blanking head 211 moves below the stamping head 303, and the part of the steel plate 4 below the stamping head 303 moves outside. When the toothless gear 202 meshes with the inner transmission gear 225, the punching head 217 punches the part of the steel plate 4 below the punching head 217, the blanking head 211 blanks the part of the steel plate 4 below the blanking head 211, and the stamping head 303 and the side stamping head 305 perform stamping forming on the part of the steel plate 4 below the stamping head 303.

[0045] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. 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, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
