Description

Technical Field

[0001] The invention belongs to the technical field of punching machines, and in particular relates to an aluminum single plate safety punching machine. Background Art

[0002] A punch press is a mechanical device used to process metal materials. It mainly uses a punch to impact, shear, and form metal materials to achieve the purpose of processing. Punches are widely used in the metal processing industry, such as manufacturing parts, punching, cutting, and drilling of metal plates. Aluminum veneer is a thin plate material made of aluminum alloy, which is usually used for building decoration and exterior wall decoration. It has a light weight and excellent strength. In the production process, it is often necessary to process it through a punch press to make the aluminum veneer into the desired shape.

[0003] However, there are some potential dangers in the use of punching machines. During the operation of the punching machine, the movement speed between the upper and lower molds is fast and the pressure is high. If the operator's body parts enter the working area, it is easy to be pinched. Most of the existing punching machines need to rely on manual loading and unloading. For materials that can be absorbed by magnets, you only need to use the punching machine safety hand to avoid body parts entering the working area. However, aluminum panels cannot be absorbed by magnets and still need to be manually loaded and unloaded, which poses a large number of safety hazards. Summary of the invention

At the same time, the use of the clutch plate can prevent the driven gear from continuing to drive the crankshaft to rotate when foreign matter appears between the upper mold and the lower mold, causing the upper mold to be forced to move downward and cause damage to the mold, thereby effectively protecting the mold.

[0007] Furthermore, a display screen is fixedly connected to the control box, a plurality of buttons are fixedly connected to the control box, a first protective shell is fixedly connected to one side of the frame, a second protective shell is fixedly connected to the side of the frame away from the first protective shell, a fixed plate is fixedly connected to the side of the frame close to the second protective shell, a second hydraulic rod is fixedly connected to the fixed plate, a second brake block is fixedly connected to the output end of the second hydraulic rod, third guide rods are fixedly connected to both sides of the upper surface of the second brake block, and the third guide rods pass through the slidably connected fixed plate.

[0008] Through the above technical solution, the second brake block can be pushed by the second hydraulic rod to stop the rotation of the brake wheel and quickly stop the rotation of the crankshaft.

[0013] Furthermore, a motor fixing frame is fixedly connected to one side of the side plate, a second motor is fixedly connected to the motor fixing frame, a first gear is fixedly connected to the output end of the second motor, a second gear is provided on the side of the side plate close to the first gear, the first gear and the second gear are meshed with each other, the first gear and the second gear respectively drive the rotating roller to rotate, flexible racks are fixedly connected to both sides of the second belt, a plurality of tooth grooves are provided on both sides of the extrusion transport roller, the tooth grooves and the flexible racks are meshed with each other, a plurality of flexible scrapers are fixedly connected to the second belt, and a pair of rubber friction sleeves are fixedly provided on the extrusion transport roller.

[0014] Through the above technical scheme, the aluminum veneer can be placed between the second belts and pushed toward the lower mold, so that a pair of extrusion transport rollers clamp the aluminum veneer and extrude it toward the lower mold to complete the loading. At this time, the rotating roller and the extrusion friction roller rotate in opposite directions, so that the belt is flipped away from the lower mold, thereby pushing the fingers of the worker away to avoid extrusion accidents. Through the use of the first hydraulic rod and the lifting frame, after the stamping operation is completed, the workpiece is tilted and lifted to allow the workpiece to be unloaded through the lower slide. During the entire production process, there is no need for the worker's body parts to enter between the upper mold and the lower mold, which effectively avoids potential safety hazards in the production process and prevents high-speed rotating machinery from injuring the worker.

[0016] Through the above technical solution, after the stamping operation is completed, the first hydraulic rod is extended to flip the lifting frame upward, and the workpiece is tilted and lifted, so that the workpiece is separated from the lower mold and unloaded through the lower slide. The aluminum sheet is transported to the top of the lower mold and is blocked by the baffle bar to stop moving.

[0017] The cam is provided with a plurality of second slide rails, the clutch plate outer sleeve is provided with a ring, the inner side of the ring is fixedly connected to a limit ring, and the two sides of the ring are fixedly connected with a protrusion, and the upper surface of the bottom of the frame is rotatably connected with a pedal, and the end of the pedal away from the frame is slidably connected with a fixing rod, the fixing rod is fixedly connected with a fixing frame, the fixing frame is fixedly connected with a pull rod, one side of the frame is fixedly connected with a baffle, the baffle is slidably connected with a second guide column, the second guide column outer sleeve is provided with a third spring, the upper end of the second guide column is fixedly connected with the moving frame, the first brake block is fixedly connected with the lower upper surface of the moving frame, guide grooves are provided on both sides of the moving frame, the protrusion penetrates the sliding connection guide groove, the lower end of the moving frame is fixedly connected with the pull rod, the pull rod penetrates the sliding connection baffle, the upper surface of the bottom end of the frame is rotatably connected with a rotating shaft, and the upper end of the rotating shaft is fixedly connected with a pressing block.

[0018] Through the above technical solution, after the pedal is stepped on, the movable frame drives the clutch disc to approach the driven gear, and through the cooperation of the pin and the locking groove, the driven gear drives the clutch disc to rotate, and the clutch disc drives the crankshaft to rotate. The crankshaft drives the upper slider to move back and forth up and down through the connecting rod, thereby performing the stamping operation. At the same time, it is only necessary to rotate the pressure block to the top of the pedal to press the pedal and keep the pedal in the stepped state to maintain the continuous operation of the punch press. When the pedal is no longer stepped on or stuck, the third spring pushes the movable frame upward to move the clutch disc away from the driven gear, and at the same time, the first brake block presses the brake disc, thereby quickly stopping the crankshaft while disconnecting the power, thereby avoiding inertia causing the crankshaft to continue to rotate, causing the upper slider to continue to move up and down, and posing a safety hazard to production.

[0019] Furthermore, the clutch disc includes a sliding disc slidably connected to the second sliding rail, the sliding disc is provided with a plurality of sliding grooves, the sliding grooves and the second sliding rail slidably cooperate with each other, the sliding disc is provided with a first limiting groove outside, the first limiting groove and the limiting ring rotatably cooperate with each other, the brake disc is provided with a plurality of through holes, the through holes are fixedly connected with a fixing ring, the through holes are slidably connected with a pin, the pin is provided with a second limiting groove, the second limiting groove and the fixing ring slidably cooperate with each other, one end of the pin is fixedly connected with a fourth spring, the end of the fourth spring away from the pin is fixedly connected with a bolt, the bolt is threadedly connected to the through hole, and the pin and the locking groove are engaged with each other.

[0020] Through the above technical solution, by using the clutch disc, when the pin enters the locking groove, power is transmitted to the crankshaft. When there is foreign matter between the upper mold and the lower mold, causing the movement of the upper mold to be stuck, the pin breaks through the thrust of the fourth spring and returns to the through hole, thereby preventing the driven gear from continuing to drive the crankshaft to rotate, causing the upper mold to be forced to move downward and cause damage to the mold. By turning the bolt, the compression amount of the fourth spring is changed, so that the force required for the pin to break through the fourth spring can be adjusted, thereby avoiding the situation where the downward pressure of the upper mold is insufficient to complete the stamping operation.

[0021] The beneficial effects of the present invention are as follows: (1) The present invention sets up a clutch mechanism. When the power mechanism is started, the upper slider does not move. Only when the pedal is stepped on, the moving frame drives the clutch plate to approach the driven gear. Through the cooperation of the pin and the locking groove, the driven gear drives the clutch plate to rotate, and the clutch plate drives the crankshaft to rotate. The crankshaft drives the upper slider to move up and down through the connecting rod, thereby performing a punching operation. At the same time, the pressing block only needs to be rotated to the top of the pedal to press the pedal and keep the pedal in the stepped state to maintain the continuous operation of the punch press. When the pedal is stepped on, the upper slider moves up and down to press the pedal. When the plate is no longer stepped on or stuck, the third spring pushes the moving frame upward, so that the clutch plate is away from the driven gear, and at the same time the first brake block presses the brake plate, so that the crankshaft stops quickly while the power is disconnected, avoiding inertia causing the crankshaft to continue to rotate, causing the upper slider to continue to move up and down, and bringing safety hazards to production; (2) The present invention uses a clutch plate, and when the pin enters the locking groove, the power is transmitted to the crankshaft. When foreign matter is present between the upper mold and the lower mold, causing the movement of the upper mold to be stuck, the pin breaks through the thrust of the fourth spring and retreats into the through hole, This prevents the driven gear from continuing to drive the crankshaft to rotate, causing the upper mold to be forced to move downward and cause damage to the mold. By turning the bolt, the compression amount of the fourth spring is changed, so that the force required for the pin to break through the fourth spring can be adjusted, thereby avoiding the situation where the downward pressure of the upper mold is insufficient to complete the stamping operation; (3) The present invention uses a transportation mechanism. When the operator loads the material, the aluminum sheet is placed between the second belts and pushed toward the lower mold, so that a pair of extrusion transport rollers clamp the aluminum sheet and squeeze it toward the lower mold to complete the loading. At this time, the rotating roller and the extrusion friction roller rotate in opposite directions, so that the belt is flipped away from the lower mold, thereby pushing the fingers of the staff away to avoid extrusion accidents. After the stamping operation is completed, the workpiece is tilted and lifted by using the first hydraulic rod and the lifting frame, so that the workpiece is unloaded through the lower slide. During the entire production process, there is no need for the body of the staff to enter between the upper mold and the lower mold, which effectively avoids the potential safety hazards in the production process. At the same time, the use of the first protective shell and the second protective shell can prevent the high-speed rotating machinery from injuring the staff. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, since the diameter of the extrusion and transport roller 58 is larger than that of the rotating roller 56, the second belt 59 does not touch the aluminum veneer, but clamps the aluminum veneer through a pair of extrusion and transport rollers 58 through the rubber friction sleeve 511 and transports it to the top of the lower mold 61 and is blocked by the baffle 66 to stop moving.

[0034] The working principle of this embodiment is as follows: the first motor 31 is started, the first motor 31 drives the active roller 32 to rotate, the active roller 32 drives the driven roller 33 to rotate through the first belt 34, the driven roller 33 drives the active gear 36 to rotate through the transmission shaft 35, and the active gear 36 drives the driven gear 37 to rotate. At this time, the pedal 716 is stepped on, the pedal 716 drives the fixed frame 714 to move downward through the fixed rod 715, the fixed frame 714 drives the moving frame 710 to move downward through the pull rod 713, and the guide on the moving frame 710 The groove 712 cooperates with the protrusion 76 to drive the collar 74 to move toward the driven gear 37, and the limiting ring 75 on the collar 74 cooperates with the first limiting groove 82 to make the collar 74 drive the clutch plate 8 close to the driven gear 37. At this time, the pin 86 enters the locking groove 311 and engages with each other, and the driven gear 37 drives the clutch plate 8 to rotate. The clutch plate 8 cooperates with the sliding groove 83 and the second slide rail 73 to drive the crankshaft 38 to rotate, and the crankshaft 38 drives the first mounting seat 22 to reciprocate up and down along the first slide rail 21 through the connecting rod 39; The staff puts the aluminum sheet between the second belts 59. At this time, the second motor 53 drives the first gear 54 to rotate, the first gear 54 drives the second gear 55 to rotate, the first gear 54 and the second gear 55 both drive the rotating roller 56 to rotate, the rotating roller 56 drives the second belt 59 to rotate, and the second belt 59 drives the extrusion and transportation roller 58 to rotate through the flexible rack 512 and the tooth groove 510. The rotation direction of the extrusion and transportation roller 58 is opposite to that of the rotating roller 56. At this time, since the diameter of the extrusion and transportation roller 58 is larger than the rotating roller 56, the second belt 59 does not touch the aluminum sheet, but clamps the aluminum sheet through a pair of extrusion and transportation rollers 58 through the rubber friction sleeve 511 and transports it to the top of the lower mold 61 to be The stop bar 66 blocks the movement. During the transportation of the aluminum veneer, the movement direction of the second belt 59 is opposite to that of the aluminum veneer. The surface of the aluminum veneer can be cleaned by the flexible scraper 513 on the second belt 59, so that the stamping effect is better. When the aluminum veneer reaches the lower mold 61, the first mounting seat 22 drives the upper mold 23 to move downward for stamping. At this time, the pressing plate 27 first cooperates with the lower mold 61 to clamp and fix the workpiece, and then the first spring 25 is compressed, and the upper mold 23 is pressed downward for stamping. After the stamping operation is completed, the first mounting seat 22 moves upward, and then the first hydraulic rod 64 is extended to turn the lifting frame 63 upward, tilt the workpiece and lift it, so that the workpiece is separated from the lower mold 61 and discharged through the lower slide 65; After the blanking is completed, the first hydraulic rod 64 is shortened to make the lifting frame 63 return to the groove 62. The upper surface of the lifting frame 63 is flush with the upper surface of the lower mold 61, which will not interfere with the stamping operation. When the rotating shaft 717 is rotated to make the pressing block 718 always located above the pedal 716, the pedal 716 can be locked in the stepped state. After the pressing block 718 is rotated, the pedal 716 is not locked, and the third spring 79 pushes the moving frame 710 to move upward. The moving frame 710 drives the clutch plate 8 away from the driven gear 37 through the collar 74, thereby disconnecting the power. At the same time, the first brake block 711 moves upward to press the brake disc 71 to prevent the crankshaft 38 from continuing to rotate under the action of inertia. When an emergency occurs, the second brake block 16 can also be pushed by the second hydraulic rod 14 to stop the brake wheel 310 from rotating, so that the crankshaft 38 stops rotating quickly. During the stamping operation, when foreign matter appears between the upper mold 23 and the lower mold 61, causing the movement of the upper mold 23 to be stuck, the pin 86 breaks through the elastic force of the fourth spring 88 and returns to the through hole 84, thereby preventing the driven gear 37 from continuing to drive the crankshaft 38 to rotate, causing the upper mold 23 to be forced to move downward and cause damage to the mold. By rotating the bolt 89, the compression amount of the fourth spring 88 is changed, so that the force required for the pin 86 to break through the fourth spring 88 can be adjusted, thereby preventing the downward pressure of the upper mold 23 from being insufficient to complete the stamping operation.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
