Description

Technical Field

[0001] The invention relates to the technical field of crimping machine blanking, in particular to an automatic crimping machine blanking device and method. Background Art

[0002] As a key piece of metal sheet processing equipment, hemming machines are widely used in fields such as automotive manufacturing and home appliance production. Their core function is to shape and reinforce the edges of sheet metal through hemming. After the hemming process is completed, an automatic unloading device must efficiently transfer the finished product to the next workstation. Its stability and reliability directly affect production efficiency and product quality. However, traditional hemming machine unloading devices face the following technical bottlenecks in long-term operation: Existing unloading devices often use a multi-roller synchronous conveying structure, with power transmitted through a gear set to drive the conveyor rollers. However, long-term gear meshing can easily lead to tooth surface wear, increased noise, and even seizure due to insufficient lubrication. Traditional lubrication methods rely on regular manual oiling or a single-direction automatic oil dripping system, which suffers from problems such as incomplete coverage and oil waste. Especially during high-speed continuous operation, lubricating oil has difficulty penetrating the tooth root area, resulting in localized lubrication failure and shortened gear life. Most equipment uses an independent power source to drive the lubrication system, lacking a linkage mechanism with the conveying action. This leads to two possible problems: first, the mismatch between lubrication frequency and conveying speed, resulting in over-lubrication or under-lubrication; second, the additional power source increases energy consumption and equipment complexity. The linear lubrication track with a fixed stroke can only cover the gear tooth top area, and there are still lubrication blind spots on the tooth side and tooth root. Summary of the Invention

The rotating motor 7 drives the second rotating rod 8 on the far right, and transmits power to the first gear 14 through the third rotating rod 15. The reciprocating screw 19 and the limit rod 18 pass through the fourth and fifth connecting holes of the movable plate 301 to realize the lateral reciprocating motion of the movable plate. The rotating motor 7 drives the second rotating rod 8 to rotate, and the conveying roller 9 rotates synchronously to convey the material. The first gear 14 drives the adjacent second gear 17 through meshing to form a continuous transmission chain. The reciprocating screw 19 is driven to rotate by the first bevel gear 23, and the movable plate 301 moves laterally under the constraints of the screw and the limit rod.

[0017] An oil leakage groove 24 is formed through the top of the third support plate 13. The surface of the limit rod 18 is fixedly connected to the limit block 21. The reciprocating screw rod 19 is located inside the limit block 21 and does not contact the limit block 21. The limit block 21 is close to the first bevel gear 23. The surface of the reciprocating screw rod 19 is fixedly connected to the second bevel gear 25. The first bevel gear 23 meshes with the second bevel gear 25.

The oil leakage groove 24 diverts excess oil to the recovery box 4, and the limit block 21 prevents the movable plate 301 from excessive movement, causing it to hit the second bevel gear 25 and cause damage to the second bevel gear 25.

[0018] A third gear 310 is fixedly connected to the bottom of the first rotating rod 309, which meshes with the gear plate 20. A driven rod 314 is fixedly connected to the back surface of the moving block 312. A cylindrical cam 313 is fixedly connected to the top of the first rotating rod 309. The surface of the cylindrical cam 313 is provided with a return groove connected end to end. The driven rod 314 is slidably connected to the groove wall of the cylindrical cam 313. The vertical distance between the return groove is equal to the vertical distance from the oil box 307 to the bottom of the first support plate 5. The third gear 310 is engaged with the gear plate 20, and the cylindrical cam 313 cooperates with the driven rod 314 through the return groove to drive the oil box 307 to move vertically. When the movable plate 301 moves horizontally, the third gear 310 rolls along the gear plate 20, driving the first rotating rod 309 to rotate. The return groove of the cylindrical cam 313 pushes the driven rod 314 to move up and down, so that the oil box 307 periodically contacts the gear surface.

[0019] A recovery box 4 is fixedly connected to the front side of the front support frame 1, and a sensor 6 is fixedly connected to the top of the first support plate 5; The recovery box 4 is installed on the front support frame 1, and the sensor 6 is set on the top of the first support plate 5 to detect the material. After the sensor 6 detects the material, it triggers the rotation motor 7 to start. The oil dripping during the lubrication process flows into the recovery box 4 through the oil leakage groove 24, and can be re-injected into the oil box 307 after filtration.

[0020] The automatic unloading method of the crimping machine adopts the automatic unloading device of the crimping machine, comprising the following steps: S1. Material conveying: When the sensor 6 detects an object on the surface of the conveying roller 9, the rotary motor 7 is started, and the second rotary rod 8 is driven by the rotary motor 7 to drive the conveying roller 9 to rotate synchronously, and a continuous conveying plane is formed by the first gear 14 and the second gear 17 that mesh with each other; S2, lubrication synchronization: When the conveying roller 9 rotates, the third rotating rod 15 drives the first gear 14 to rotate, and the fifth rotating rod 22 and the first bevel gear 23 drive the reciprocating screw 19 to rotate, so that the movable plate 301 moves back and forth laterally along the limit rod 18; S3, Adaptive lubrication: When the movable plate 301 moves laterally, the engagement between the third gear 310 and the toothed plate 20 drives the first rotating rod 309 to rotate, and the cooperation between the cylindrical cam 313 and the driven rod 314 causes the oil box 307 to generate vertical reciprocating motion; S4, cyclic lubrication: When the oil box 307 descends, it contacts the first gear 14 and the second gear 17 through the sponge 308 and applies oil to the surface. When it rises, it separates from the tooth surface to complete a single lubrication cycle; S5, residual oil recovery: the oil dripping during the lubrication process flows into the recovery box 4 through the oil leakage groove 24 for recycling; The movement path of the oil box 307 is a wavy linear motion, which is the same as the path formed on the upper surface of the gear set. By coordinating vertical motion and linear motion, the oil box 307 completes the wavy linear motion, achieving close lubrication of the gear set and preventing the second gear 17 from being insufficiently lubricated. After the material triggers the sensor 6, the conveying roller 9 starts to rotate, and the gear transmission drives the reciprocating screw 19. While the oil box 307 moves laterally, it is lifted and lowered vertically through the cylindrical cam 313, forming a wave path to smear the oil. The waste oil is recycled through the recovery box 4. When the conveying roller 9 rotates, the power is transmitted to the reciprocating screw 19 through the bevel gear, driving the oil box 307 to move laterally; the third gear 310 engages with the tooth plate 20 to drive the cylindrical cam 313 to rotate, and the driven rod 314 moves along the return groove, causing the oil box 307 to lift and lower vertically. The two combine to form a wave motion, and the sponge 308 forms a uniform oil film on the gear surface.

[0021] In the present invention, when the sensor 6 detects the presence of material on the surface of the conveyor roller 9, it triggers the rotation motor 7 to start, and the motor output shaft drives the second rotating rod 8 on the far right to rotate through the coupling, thereby driving the conveyor roller 9 fixed on its surface to rotate; the eleven second rotating rods 8 are arranged in a linear array, and the front end of each rotating rod is fixed to the first gear 14 through the third rotating rod 15, and the adjacent first gears 14 are meshed and connected by the second gear 17. This design allows power to be transmitted step by step from the right motor end to the left, forming a continuously meshing gear transmission chain, ensuring the synchronous rotation of the eleven conveyor rollers 9 and forming a stable material conveying plane. During the conveying process, the meshing accuracy of the gear set 14 / 17 directly affects the transmission smoothness, and the intervention of the lubrication system ensures the long-term stable operation of the gears. The lubrication action forms a mechanical linkage with the conveying system. When the first gear 14 on the far right rotates with the second rotating rod 8, the fifth rotating rod 22 at its front end drives the first bevel gear 23 to rotate. The first bevel gear 23 meshes with the second bevel gear 25 on the reciprocating screw 19, converting the horizontal rotational motion into vertical screw rotation. The thread of the reciprocating screw 19 cooperates with the fourth connecting hole 302 of the movable plate 301, and under the constraint of the limit rod 18, drives the lubrication component 3 to reciprocate laterally along the tooth plate 20. The lateral movement of the mobile plate 301 triggers a dual action: Transverse motion synchronization: The third gear 310 fixed to the movable plate 301 engages with the toothed plate 20, driving the first rotating rod 309 to rotate; Vertical reciprocating motion: The cylindrical cam 313 at the top of the first rotating rod 309 has a folding groove connected end to end on its surface. The driven rod 314 is embedded in the groove and moves up and down as the cam rotates. The vertical stroke of the folding groove precisely matches the height of the gear meshing surface, driving the second L-shaped plate 306 and the oil box 307 to perform vertical reciprocating motion. The combined motion of lateral movement and vertical lifting causes the oil cartridge 307 to form a wavy trajectory, completely covering the tooth tops and roots of the first and second gears 14 and 17. As the oil cartridge 307 descends, the sponge 308 is pressed into contact with the gear surfaces, evenly applying the absorbed lubricant. As the cartridge 307 ascends, it disengages the meshing area to prevent over-lubrication. This design ensures that every gear meshing surface is fully covered in a single stroke, eliminating the dead angle problem associated with traditional linear lubrication. During the lubrication process, excess oil drips from the gear surface into the oil leakage groove 24 of the third support plate 13 and is then diverted into the front recovery box 4. The recovery box has a built-in filter layer that can separate impurities such as metal debris. The purified oil can be re-injected into the oil box 307 through the oil filling port, forming a closed circulation system. The sensor 6 monitors the material status in real time and automatically cuts off the motor power supply when there is no material, and the lubrication operation is stopped simultaneously, further reducing energy consumption and oil loss. Reciprocating screw and limit block: The limit block 21 is fixed to the surface of the limit rod 18 to limit the maximum stroke of the movable plate 301 and prevent it from excessive movement causing the second bevel gear 25 to collide with the first bevel gear 23; Cylindrical cam precision control: The vertical stroke of the return groove is equal to the distance from the highest point of the oil box 307 to the contact gear surface, ensuring that the sponge 308 contacts the tooth surface with constant pressure, avoiding insufficient lubrication or oil splashing due to uneven pressure; Gear group power distribution: Eleven first gears 14 and ten second gears 17 are alternately meshed to form a stable power distribution network. Even the far-end conveying roller can still maintain the same speed as the motor end, eliminating the risk of material conveying jams.

[0022] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of the invention.
