Description

[0002] In the modern industrial manufacturing process, punching operation is a common and important process, which is widely used in the processing of metal, plastic, wood and other materials. The fully automatic double-head punching machine is a processing equipment that integrates automation, intelligence and high efficiency. It is designed for precise punching of various bars and other materials. It is often used in metal processing, woodworking, plastic products and building materials. It has a double-head working mode and can perform punching operations at two different positions or on both sides of the same workpiece at the same time, greatly improving processing efficiency.

[0003] A Chinese patent discloses: a double-head punching machine, patent announcement number: CN221134133U, the patent "This utility model relates to the technical field of punching machines, and discloses a double-head punching machine, including a machine table, the upper end of the machine table is fixedly connected with a mounting seat and a mounting frame, the upper end of the mounting seat is fixedly connected with a stepper motor, the output end of the stepper motor is fixedly connected with a lead screw, the circumferential surface of the lead screw is threadedly connected with a fixed seat, the fixed seat and the mounting seat are slidably connected by a guide rail, a punching mechanism is arranged on the upper end of the fixed seat, a support frame is fixedly connected to the lower end of the mounting frame, a gap is left between the support frame and the mounting frame, through holes are provided on the surface of the mounting frame and the support frame, a slide groove is provided in the support frame, and a pull-out positioning module is slidably connected in the slide groove".

[0004] Although the equipment adopts the method of avoiding air so that the aluminum chips generated during punching will fall down and be discharged through the chip removal channel, the double-head punching machine lacks the automatic loading and unloading function, which leads to the reliance on manual labor to place and remove materials during the production process, which brings many limitations and problems. First of all, since the speed of manual operation is much lower than the punching efficiency of the equipment, the high-efficiency performance of the equipment cannot be fully utilized, the entire production cycle is extended, and the overall production capacity is directly reduced. Especially in large-scale production, the speed of manual loading and unloading becomes the bottleneck of the production line. Secondly, inaccurate positioning is prone to occur during manual loading and unloading, causing the material to deviate from the correct position before punching, which in turn causes deviation in the drilling position, affecting the processing quality and consistency of the product. In addition, the manual loading and unloading process with high repetitiveness requires long-term operation, which not only wastes human resources, but also easily leads to reduced production efficiency and errors due to worker fatigue, affecting production efficiency.

[0016] Beneficial effects of the present invention:

[0017] 1. The fully automatic double-head punching machine uses the loading and unloading mechanism. The punching motor pushes or pulls the push block when it is away from or close to the punching table. The push block pushes the loading and unloading blocks to slide upward through the rollers. When the loading and unloading blocks slide upward, the punched rods are pushed out into the punching limit slots. During the pushing process, the loading and unloading blocks will lift the rods inside the loading inclined plate into the punching limit slots, so that the loading and unloading operations can be performed, achieving automatic loading and unloading, which is not restricted by the speed of manual operation, ensuring the consistency of the punching process, and reducing the dependence on manual operation, saving time and effort, significantly improving the efficiency of the production line, and solving the problem that the speed of manual operation is far lower than the punching efficiency of the equipment, directly reducing the overall production capacity, and avoiding human error. Inaccurate positioning is prone to occur during the loading and unloading process, causing the material to deviate from the correct position before punching. Manual loading and unloading has high repetitiveness, and it is easy to reduce production efficiency and errors due to worker fatigue. The loading and unloading mechanism effectively automates the placement and removal of bar materials, avoids the tedious operation of manual intervention, significantly improves production efficiency, can give full play to the processing capacity of the double-head punching machine, shortens the production cycle, and ensures consistency in the punching process without manual loading and unloading, reducing rework and scrap rate caused by positioning errors. At the same time, automatic loading and unloading also reduces labor costs, saves time and effort, avoids fatigue and reduced efficiency caused by long-term repetitive operations, and improves overall work efficiency.

[0018] 2. The fully automatic double-head punching machine, when the punching plate in the vibration mechanism moves downward or upward, drives the tooth plate to move, and then drives one end of the hammer to repeatedly knock on the side wall of the storage box, causing the storage box to vibrate. Through this knocking action, it effectively prevents the accumulation of multiple bars, causing the upper bars to squeeze the lower bars and then block the discharge port of the storage box, ensuring that the bars can be discharged from the storage box smoothly through the roller, preventing production stagnation due to blockage, and improving production continuity and efficiency.

[0019] 3. The fully automatic double-head punching machine also drives the incomplete gear to rotate through the tooth groove when the push plate drives the push block to slide, thereby driving the sliding plate and the porous water spray pipe to slide left and right, thereby increasing the impact area of ​​the water spray from the hole water spray pipe, and cleaning the impurities on the workbench in time. The cleaning process can cover a larger area of ​​the workbench to ensure comprehensive cleaning. The cleaning water can be returned to the water tank again after filtration, realizing the reuse of water resources, greatly reducing the water consumption in the production process, and complying with the concept of energy conservation and environmental protection.

[0036] For further information, see Attachment Figures 1 to 7 As shown, the loading and unloading mechanism includes a loading plate 14 fixedly connected to the side wall of the punching table 9, a slope inclined toward the punching table 9 is provided on the top of the loading plate 14, unloading connecting grooves 15 are provided on both sides of the top of the punching table 9, and slide grooves 16 are provided on both sides of the inner wall of the punching table 9. Upper and lower material blocks 17 are slidably connected between the slide grooves 16 through sliders. The shapes of the two sides of the upper and lower material blocks 17 are concave, and the shapes of the top two sides of the upper and lower material blocks 17 are provided with inclined parts 18. The two sides of the upper and lower material blocks 17 extend into the unloading connecting groove 15 respectively, and the bottom of the upper and lower material blocks 17 is fixedly connected with rollers. Wheel 19, the top of the workbench 2 is slidably connected with a pushing block 20 near the bottom of the upper and lower material blocks 17, the outer wall of the roller 19 is in contact with the top of the pushing block 20, and the pushing blocks 20 are fixedly connected with pushing plates 21 on both sides, one end of the pushing plates 21 is respectively fixedly connected to the top of the carrying plate 5, and the bottom of the storage box 22 is fixedly connected with a loading inclined plate 23, and the loading inclined plate 23 is close to the punching table 9. Both sides are provided with loading grooves 24, and the two opposite surfaces of the loading inclined plate 23 are fixedly connected with an anti-drop block 25, and the side wall of the punching table 9 is fixedly connected with a material unloading inclined plate 26;

[0037] When the loading and unloading mechanism is in use, firstly, the bar material to be punched is placed into the storage box 22, and the bar material will roll into the loading inclined plate 23 by gravity, and the bar material in the loading inclined plate 23 is limited by the anti-drop block 25 to prevent the bar material behind from being squeezed out of the loading inclined plate 23, and then the power is turned on, and the first electric telescopic rod 8 is started at both ends of the top of the workbench 2, and the first electric telescopic rod 8 drives the bearing plate 5 and the slider 4 to slide to the side away from the punching table 9, and when the bearing plate 5 slides, it will pull the push plate 21, and the push plate 21 drives the push block 20 to slide on the top of the workbench 2, and the push block 20 squeezes the roller 19 by its own inclination, and the roller 19 slides on the top of the push block 20 and squeezes the loading and unloading block 17, and when the loading and unloading block 17 slides, it will pass through the loading The through slot 24 lifts up the rod at the top of the loading through slot 24. When the rod is lifted up, it will roll to the top of the loading plate 14 and contact the other side of the upper and lower material blocks 17. When drilling, the first electric telescopic rod 8 pushes the supporting plate 5 and the punching motor 6 to move in the direction of the punching table 9. When the supporting plate 5 moves, it will push the pushing block 20 through the pushing plate 21. At this time, the roller 19 will gradually move downward through the slope of the side wall of the pushing block 20. Then, through the gravity of the upper and lower material blocks 17, the upper and lower material blocks 17 will also move downward and shrink back into the unloading connecting groove 15, thereby releasing the limit on the rod. The rod will roll into the punching limit groove 13, and then the second electric telescopic rod 11 will be started. The second electric telescopic rod 11 drives the limit punching plate 12 to move downward and contact the top of the punching table 9. The first electric telescopic rod 8 is in contact with the punching motor 6, thereby fixing and limiting the rod material in the punching limit groove 13. After limiting, the first electric telescopic rod 8 continues to extend to drive the punching motor 6 to move toward the punching table 9. At this time, the punching head 7 will synchronously contact the two ends of the rod material, and then start the punching motor 6. The punching motor 6 drives the punching head 7 to rotate and perform a punching operation on the rod material. After the punching is completed, the first electric telescopic rod 8 contracts and drives the punching motor 6 to move away from the punching table 9 through the supporting plate 5. Then the supporting plate 5 will repeat the operation and push the roller 19 and the upper and lower material blocks 17 upward through the pushing block 20. When the upper and lower material blocks 17 move upward, they will extend out of the unloading connecting groove 15 through one side of the upper and lower material blocks 17 and push the punched rod material to leave the punching limit groove 13. Then the rod material The rods will roll onto the unloading inclined plate 26, and a container can be placed at the bottom of one end of the unloading inclined plate 26, so that the rods can be rolled into the container through the unloading inclined plate 26, and then the unloading operation is completed. At the same time, the rods are lifted up again through the other side of the loading and unloading block 17 for loading and unloading operation. Through the unloading and unloading mechanism, the punching motor 6 will push or pull the pushing block 20 when it is away from and close to the punching table 9, and the pushing block 20 pushes the unloading and unloading block 17 to slide upward through the roller 19. When the unloading and unloading block 17 slides upward, the punched rods will be pushed out into the punching limit groove 13. During the pushing process, the unloading and unloading blocks 17 will lift the rods inside the loading inclined plate 23 into the punching limit groove 13, so that the loading and unloading operation can be performed, achieving automatic loading and unloading, and is not restricted by the manual operation speed.It ensures consistency in the punching process, reduces reliance on manual operation, saves time and effort, significantly improves production line efficiency, solves the problem that the speed of manual operation is far lower than the punching efficiency of the equipment, directly reduces overall production capacity, and avoids the problem of inaccurate positioning during manual loading and unloading, which causes the material to deviate from the correct position before punching. The manual loading and unloading has high repetitiveness, which is easy to cause reduced production efficiency and errors due to worker fatigue. This loading and unloading mechanism effectively automates the placement and removal of bar materials, avoids the tedious operation of manual intervention, significantly improves production efficiency, can give full play to the processing capacity of the double-head punching machine, shortens the production cycle, and ensures consistency in the punching process without manual loading and unloading, reduces rework and scrap rate caused by positioning errors, and automatically loads and unloads materials to reduce labor costs, save time and effort, avoid fatigue and reduced efficiency caused by long-term repeated operations, and improve overall work efficiency. ,

[0038] For further information, see Attachment Fig. 9 As shown, the vibration mechanism includes a striking hammer 27 rotatably connected to the top of the support platform 10, a connecting groove 28 is opened on the top of the support platform 10, and the two sides of the top of the connecting groove 28 are fixedly connected to the inner side of the supporting vertical plate 29, and the rotating top block 30 is rotatably connected between the opposite surfaces of the supporting vertical plate 29, and the shaft portion of the rotating top block 30 is fixedly connected to the outside with a gear 31, and the bottom of the striking hammer 27 is fixedly connected to a semicircular block 32 near the top of the rotating top block 30, and the bottom of one end of the striking hammer 27 near the storage box 22 is fixedly connected to a tension spring 33, and one end of the tension spring 33 is fixedly connected to the top of the support platform 10, and the side wall of the limiting punching plate 12 is fixedly connected to a toothed plate 34, and one end of the toothed plate 34 passes through the connecting groove 28 and meshes with the side wall of the gear 31.

[0039] When the vibration mechanism is in use, when the second electric telescopic rod 11 drives the limit punching plate 12 to move downward or upward, the limit punching plate 12 will drive the tooth plate 34 to move, thereby driving the gear 31 to rotate. When the gear 31 rotates, it drives the rotating top block 30 to rotate, and the rotating top block 30 contacts the outside of the semicircular block 32, and repeatedly lifts the percussion hammer 27. Whenever the percussion hammer 27 is lifted, the tension spring 33 will be pulled, and then the tension spring 33 will shrink and pull the percussion hammer 27 to rotate, and one end of the percussion hammer 27 will repeatedly knock on the side wall of the storage box 22 to vibrate the storage box 22. Through this knocking action, it is effectively prevented that the upper layer of bars squeezes the lower bars due to the accumulation of multiple bars, thereby blocking the discharge port of the storage box 22, and ensuring that the bars can be smoothly discharged from the storage box 22 through the roller.

[0040] For further information, see Attachment Figure 8 and Fig.10As shown, a baffle plate 35 is fixedly connected to the top of the workbench 2, a sliding plate 36 is slidably connected to one side of the baffle plate 35 and the punching table 9, a porous water spray pipe 37 is fixedly connected to the bottom of the sliding plate 36, a telescopic rod 38 is rotatably connected to the side wall of the sliding plate 36, one end of the telescopic rod 38 is fixedly connected to an incomplete gear 39, the shaft of the incomplete gear 39 is rotatably connected to the top of the workbench 2, a plurality of equidistant and uniform tooth grooves 40 are provided on the side wall of the push plate 21, the outer wall of the incomplete gear 39 is meshed with the outer part of the tooth groove 40, a water tank 41 is fixedly connected to the side wall of the support frame 1, a water suction pump 42 is fixedly connected to the side wall of the water tank 41, a water delivery pipe 43 is fixedly connected to the output end of the water suction pump 42, one end of the water delivery pipe 43 passes through the top of the workbench 2 and is interconnected with one end of the porous water spray pipe 37, and a gear 43 for discharging water is fixedly connected between the inner walls of the water tank 41. The filter screen 44 for filtering impurities in the water will cause more impurities to fall onto the top of the workbench 2 when holes are punched. The water suction pump 42 is started, and the water suction pump 42 pumps water into the water pipe 43. The water pipe 43 delivers water to the porous water spray pipe 37, and the impurities on the top of the workbench 2 are flushed into the water tank 41 through the porous water spray pipe 37. When the push plate 21 moves, the tooth groove 40 of the side wall engages with the incomplete gear 39 to drive the incomplete gear 39 to rotate. When the incomplete gear 39 rotates, the telescopic rod 38 is driven to rotate. When the telescopic rod 38 rotates, the sliding plate 36 and the porous water spray pipe 37 are driven to slide on the inside of the shielding plate 35, thereby increasing the impact area of ​​the porous water spray pipe 37 when flushing water. The water mixed with impurities will pass through the filter screen 44 to filter out the impurities in the water, so that the water flows back into the filter screen 44, and then it can be reused, saving the waste of water resources.

The cooling water spray pipe 46 sprays water onto the contact surface between the punching head 7 and the rod material for cooling, so as to avoid the situation where the temperature of the punching head 7 is too high when punching, causing the punching head 7 to be worn or deformed.

[0042] For further information, see Attachment Fig. 9 As shown, the side wall of the percussion hammer 27 is fixedly connected with a flexible pad and contacts the outer wall of the material storage box 22. By providing the flexible pad, the percussion hammer 27 is in flexible contact with the material storage box 22, thereby increasing the service life of the percussion hammer 27.

[0043] For further information, see Attachment Figure 6As shown, the inner wall of the punching limit groove 13 is fixedly connected with a plurality of anti-skid protrusions which are evenly and equidistantly arranged. The anti-skid protrusions increase the friction of the rod inside the punching limit groove 13 to prevent the rod from slipping during punching.
