Description

Technical Field

[0001] The invention belongs to the technical field of aluminum veneer processing equipment, and specifically relates to automatic punching equipment for aluminum veneer production. Background Art

[0002] Aluminum veneer is a plate made of aluminum alloy, usually used in building exterior wall decoration, billboard production, interior decoration and other fields. It is generally flat, with high surface flatness and finish, light weight, high strength, easy processing, good decorative properties, etc., which can meet different design needs and environmental requirements. When processing aluminum veneer, punching is also one of the indispensable steps. The punching methods include laser punching and mechanical punching. Laser punching: using laser technology to punch aluminum veneer, laser punching can achieve finer holes and complex patterns, suitable for projects with high customization requirements; mechanical punching: using a special aluminum plate punching machine or punching machine for mechanical punching, this method is suitable for mass production and precise control of hole size and position requirements.

[0003] When punching holes in aluminum veneers, the existing aluminum veneer punching equipment first places the aluminum veneer on a machine tool and fixes it with a clamp on the machine tool. However, the punching needle moves up and down repeatedly and cannot move. The fixed aluminum veneer is driven to move by the movement of the clamp to achieve punching holes in different areas of the aluminum veneer. Although this punching method can achieve mass production, it still has some shortcomings. After each punching of the aluminum veneer is completed, the clamp needs to be manually operated to load and unload the material, which greatly affects the processing efficiency. At the same time, when punching holes in large quantities of aluminum veneers, the holes cannot be punched at one time. The punching method of punching holes one by one or in rows is inefficient and cannot punch large quantities of aluminum veneers within a limited time. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an automatic punching equipment for the production of aluminum veneer.

[0005] The technical solution adopted to solve the above technical problems is: an automatic punching device for aluminum single plate production, comprising a support mechanism, a feeding mechanism is provided on one side of the support mechanism;

[0006] A driving mechanism is installed at the central top of the support mechanism, and a feeding mechanism is installed on the support mechanism at an upper position on one side close to the feeding mechanism;

[0007] A punching die assembly is installed at the center of the support mechanism, a punching mechanism is installed on the driving mechanism and close to the upper position of the punching die assembly, and a linkage mechanism is installed at the rear end of the support mechanism;

[0008] A feeding rack is fixedly connected to the other side of the supporting mechanism, and a plurality of aluminum single plate bodies are arranged on the feeding mechanism.

[0009] Furthermore, the support mechanism comprises a support base frame, the top of the support base frame is fixedly connected to a mounting frame, and the inner walls of the front and rear ends of the mounting frame are fixedly connected to limit strips.

[0010] Through the above technical solution, the stability of the punching mechanism when moving up and down is improved, thereby improving the punching accuracy of the aluminum single plate body.

[0011] Furthermore, the feeding mechanism includes a feeding rack arranged on one side of the supporting base frame, a conveyor belt is installed on the feeding rack, and a plurality of feeding troughs are opened on the conveyor belt.

[0012] Through the above technical scheme, it is necessary to punch holes in the main body of the aluminum veneer. The staff will place multiple main bodies of the aluminum veneer into the feeding trough on the conveyor belt one by one, and transport them to the loading mechanism through the conveyor belt, so that the loading mechanism can load the main bodies of the aluminum veneer into the die assembly in turn to realize punching thereof.

[0013] Furthermore, the driving mechanism includes a first rotating shaft rotatably connected to the center of the mounting frame, a driven wheel is fixedly connected to the rear end of the outer wall of the first rotating shaft, a driving motor is fixedly connected to the top rear end of the supporting frame, a driving wheel is fixedly connected to the outer wall of the output shaft of the driving motor, and a synchronous belt is directly connected to the driving wheel and the driven wheel.

[0014] Through the above technical solution, the drive motor is started, and the drive motor drives the drive wheel to rotate through the output shaft, and drives the driven wheel to rotate with the synchronous belt, thereby driving the first rotating shaft to rotate, and then driving the feeding mechanism, the die assembly, the punching mechanism and the linkage mechanism. Through the drive of a drive motor, the steps of loading, punching and unloading the aluminum single plate body are completed, which greatly reduces the stamping cost of the equipment.

[0015] The cam is connected with the first end of the support frame, and the cam is connected with the second end of the support frame by the first and second connecting rods.

[0016] Through the above technical solution, when the aluminum single plate body is conveyed to one end of the conveyor belt, the first rotating shaft rotates to drive the first rotating ear to rotate, so that the first rotating ear rotates to drive the movable seat to rotate, and then drives the connecting rod to swing, so that the connecting rod drives the second rotating ear to rotate, and the second rotating ear rotates to drive the first connecting shaft to rotate, so that the first connecting shaft drives the two swing arms to swing, and then drives the loading rack to rotate. When the contact point between the movable seat and the connecting rod is close to the highest point, the loading rack is rotated to the top of the aluminum single plate body. At this time, the multiple first suction cups on the loading rack are just in contact with the aluminum single plate body. The first air pump is started at this time, and air is sucked to the multiple first suction cups through the third connecting pipe and the second connecting pipe, so as to suck the aluminum single plate body. The first rotating shaft continues to rotate, and drives the second rotating ear to swing downward, thereby driving the two swing arms to swing toward the die assembly through the first connecting shaft, and then drives the sucked aluminum single plate body to rotate toward the die assembly. When the feeding rack rotates back and forth, the connected movable shaft slides up and down in the connecting sleeve to play a limiting role. The whole process does not require manual feeding by the staff, and the device automatically feeds, which greatly improves the punching efficiency.

[0017] Furthermore, the die assembly includes a second rotating shaft rotatably connected to the center of the supporting base frame, the outer wall of the second rotating shaft is fixedly connected to a polygonal bottom mold, the outer wall of the polygonal bottom mold is provided with a plurality of evenly distributed positioning grooves, the interior of the polygonal bottom mold is provided with a plurality of discharge cavities, a plurality of punching grooves are provided on the polygonal bottom mold and located in the plurality of positioning grooves, the plurality of punching grooves respectively penetrate the corresponding discharge cavities, the four corners of the plurality of positioning grooves are fixedly connected with second suction cups, the plurality of second suction cups are fixedly connected with corresponding fourth connecting pipes, a second air pump is fixedly installed on the top front end of the supporting base frame, and a fifth connecting pipe is fixedly connected between the second air pump and the plurality of fourth connecting pipes.

[0018] Through the above technical scheme, when the aluminum veneer body is sent to the positioning groove on the inclined surface of the polygonal bottom mold, the second air pump starts to work, and the second air pump exhausts the multiple second suction cups connected through the fifth connecting pipe and the fourth connecting pipe, so that the multiple second suction cups suck the fitted aluminum veneer body, and the polygonal bottom mold continues to rotate, and the sucked aluminum veneer body is rotated to the bottom of the punching mechanism, and it is punched by the punching mechanism. The punched aluminum sheet falls into the connected discharge cavity through the punching groove. When the polygonal bottom mold continues to rotate, it is convenient to drive the aluminum sheet in the discharge cavity to be discharged outward. At the same time, after punching, the multiple second suction cups at the bottom of the aluminum veneer body stop exhausting, so that the aluminum veneer body falls onto the unloading rack due to gravity, completing the punching process. While the polygonal bottom mold is rotating, a new aluminum veneer body is sucked and punched, and the work is reciprocating.

[0019] Furthermore, the punching mechanism includes a plurality of eccentric wheels fixedly connected to the outer wall of the first rotating shaft, a movable plate is provided in the mounting frame and near the lower position of the plurality of eccentric wheels, the front and rear ends of the movable plate are fixedly connected to the limiting slide seat, the four corners of the top of the movable plate are fixedly connected to the limiting column, the top of the movable plate and the corresponding outer wall position of the limiting column are fixedly connected with a first spring, the four corners of the bottom of the movable plate are fixedly connected with a connecting column, a pressure plate is fixedly connected between the bottom ends of the plurality of connecting columns, the top of the pressure plate and the corresponding outer wall position of the connecting column are fixedly connected with a second spring, the bottom of the movable plate is fixedly connected with a plurality of evenly distributed punching needles, and the top of the pressure plate is provided with through holes corresponding to the plurality of punching needles.

[0020] Through the above technical scheme, when the polygonal bottom mold drives the aluminum veneer body to rotate to just below the pressure plate, the first rotating shaft rotates to drive the multiple eccentric wheels to rotate, so that the multiple eccentric wheels rotate to extrude the movable plate, so that the movable plate extrude the pressure plate through the multiple connecting columns, so that the pressure plate presses the aluminum veneer body. At this time, when the multiple eccentric wheels continue to rotate, they drive the multiple punching needles to punch the aluminum veneer body and penetrate the corresponding through holes. At this time, the multiple eccentric wheels are the lowest point for extruding the movable plate. When the multiple eccentric wheels continue to rotate, the multiple first springs drive the movable plate to slowly reset, and then drive the multiple punching needles to slowly reset. At the same time, the multiple second springs drive the pressure plate to slowly reset, so as to punch the next aluminum veneer body.

[0021] Furthermore, the two limit slides are slidably connected to the corresponding limit strips, and the top ends of the plurality of limit columns penetrate the top of the mounting frame. In the assembled state, the plurality of punching needles respectively penetrate the corresponding through holes and punching grooves.

[0022] Through the above technical solution, by designing the limiting slide, limiting strip and limiting column, the stability of multiple punches during punching is greatly improved, thereby improving the punching quality.

[0023] Furthermore, the linkage mechanism includes a first gear fixedly connected to the rear end of the outer wall of the first rotating shaft, the rear end outer wall of the mounting frame is rotatably connected to the first mounting shaft near the lower position of the first gear, the outer wall of the first mounting shaft is fixedly connected to the second gear, the rear end outer wall of the mounting frame is rotatably connected to the second mounting shaft near the lower position of the second gear, the outer wall of the second mounting shaft is fixedly connected to the third gear near the lower position of the second gear, the rear end of the outer wall of the second mounting shaft is fixedly connected to a rotating sleeve, a movable head is fixedly connected to the rotating sleeve, a movable groove is provided on the outer wall of the rotating sleeve near the movable head, and the rear end of the outer wall of the second rotating shaft is fixedly connected to a partition plate, and the partition plate is provided with a plurality of evenly distributed notches.

[0024] Through the above technical scheme, the rotation of the first shaft drives the first gear to rotate, the rotation of the first gear drives the second gear to rotate, the rotation of the second gear drives the third gear to rotate, and then drives the second installation shaft to rotate, so that the rotation of the second installation shaft drives the rotating sleeve to rotate, and the rotation of the rotating sleeve drives the movable head to rotate. When the movable head rotates to a nearby slot, it drives the partition plate to rotate. When the partition plate rotates, the contact point with the movable head moves in the movable slot, and thus does not affect the rotation of the partition plate. When the partition plate is rotated by a certain angle through the movable head, the arc surface on the partition plate fits with the outer wall of the rotating sleeve, thereby limiting the partition plate to prevent the partition plate from reversing, thereby improving the stability of the polygonal bottom mold.

[0025] Furthermore, the first gear is meshed with the second gear, and the second gear is meshed with the third gear.

[0026] Through the above technical solution, the rotation directions of the first gear and the third gear are the same, so that when the polygonal bottom mold rotates, it is not only convenient for the loading mechanism to load materials, but also convenient for unloading the punched aluminum single plate body.

[0027] The beneficial effects of the present invention are as follows: (1) The present invention designs a feeding mechanism, a loading mechanism, a die assembly and a unloading rack, and the device can automatically load the aluminum veneer on the conveyor belt. After the punching is completed, the device can unload the material by its own gravity without manual loading and unloading, which not only reduces the labor cost but also improves the punching efficiency; (2) The present invention designs a driving mechanism and a linkage mechanism, and drives the entire device to load, punch and unload materials through a motor, and the operation of each mechanism in the whole process is compact, which not only reduces the operation cost of the equipment but also improves the punching efficiency of the aluminum veneer; (3) The present invention designs a punching mechanism, and a plurality of punching needles are installed on the movable plate, which can punch a plurality of holes in the aluminum veneer at one time, meeting the needs of large-scale production with high efficiency.

[0043] like Figure 1-4As shown, a feeding mechanism 4 is installed on the upper position of the support mechanism 1 and close to the feeding mechanism 2. The feeding mechanism 4 includes a first rotating ear 401 fixedly connected to the front end of the outer wall of the first rotating shaft 301, a movable seat 402 is rotatably connected to the first rotating ear 401, and a connecting rod 403 is connected to the bottom end of the movable seat 402.

When the contact point between the movable seat 402 and the connecting rod 403 is close to the highest point, the loading rack 407 is rotated to the top of the aluminum single plate body 9. At this time, the multiple first suction cups 411 on the loading rack 407 are just in contact with the first suction cups 411 on the loading rack 407. The aluminum single plate body 9 is fitted, and the first air pump 413 is started at this time.

The whole process does not require manual loading by the staff. The device automatically loads materials, which greatly improves the punching efficiency.

The punched aluminum sheet falls into the connected discharge cavity 504 through the punching groove 505. When the polygonal bottom mold 502 continues to rotate, it is convenient to drive the aluminum sheet in the discharge cavity 504 to be discharged outward. At the same time, the multiple second suction cups 506 at the bottom of the aluminum veneer body 9 after punching stop pumping, so that the aluminum veneer body 9 falls onto the unloading rack 8 due to gravity, completing the punching process on it. While the polygonal bottom mold 502 is rotating, a new aluminum veneer body 9 is sucked and punched, and the work is reciprocating.

[0045] like Figure 1-9As shown, a punching mechanism 6 is installed on the driving mechanism 3 and near the upper position of the die assembly 5, and the punching mechanism 6 includes a plurality of eccentric wheels 601 fixedly connected to the outer wall of the first rotating shaft 301, and a movable plate 602 is provided in the installation frame 102 and near the lower position of the plurality of eccentric wheels 601, and the front and rear ends of the movable plate 602 are fixedly connected to the limiting slide 603, and the four corners of the top of the movable plate 602 are fixedly connected to the limiting columns 604, and the top of the movable plate 602 and the outer wall positions of the corresponding limiting columns 604 are fixedly connected to the first spring 605, and the movable plate 6 The bottom four corners of the movable plate 602 are fixedly connected with connecting columns 606, and the bottom ends of the multiple connecting columns 606 are fixedly connected with a pressing plate 607. The top of the pressing plate 607 and the outer wall of the corresponding connecting column 606 are fixedly connected with a second spring 608. The bottom of the movable plate 602 is fixedly connected with multiple evenly distributed punching pins 609. The top of the pressing plate 607 is provided with through holes 610 corresponding to the multiple punching pins 609. When the polygonal bottom mold 502 drives the aluminum single plate body 9 to rotate to the bottom of the pressing plate 607, the first rotating shaft 301 rotates to drive the multiple eccentric wheels 6 01 rotates, so that the multiple eccentric wheels 601 rotate and squeeze the movable plate 602, so that the movable plate 602 squeezes the pressure plate 607 through the multiple connecting columns 606, so that the pressure plate 607 presses the aluminum single plate body 9. At this time, when the multiple eccentric wheels 601 continue to rotate, they drive the multiple punching needles 609 to punch the aluminum single plate body 9 and penetrate the corresponding through holes 610. At this time, the multiple eccentric wheels 601 are the lowest point of squeezing the movable plate 602.

When the movable head 707 rotates to the adjacent notch 710, it drives the partition plate 709 to rotate. When the partition plate 709 rotates, the contact point with the movable head 707 is movable in the movable groove 708, so as not to affect the rotation of the partition plate 709. After a certain angle, the arc surface on the dividing plate 709 fits with the outer wall of the rotating sleeve 706, thereby limiting the dividing plate 709 to prevent the dividing plate 709 from reversing, thereby improving the stability of the polygonal bottom mold 502, and the first gear 701 is meshed with the second gear 703, and the second gear 703 is meshed with the third gear 705, so that the rotation directions of the first gear 701 and the third gear 705 are the same, so that when the polygonal bottom mold 502 rotates, it is not only convenient for the loading mechanism 4 to load the material, but also convenient for unloading the punched aluminum single plate body 9.

[0047] The working principle of this embodiment is as follows: the staff places multiple aluminum single plate bodies 9 into the feeding trough 203 on the conveyor belt 202 one after another, and then transports them through the conveyor belt 202. When the aluminum single plate body 9 is transported to one end of the conveyor belt 202, the driving motor 303 is started, and the driving motor 303 drives the driving wheel 304 to rotate through the output shaft rotation, and cooperates with the synchronous belt 305 to drive the driven wheel 302 to rotate, thereby driving the first rotating shaft 301 to rotate, and the rotation of the first rotating shaft 301 drives the first rotating ear 401 to rotate, so that the rotation of the first rotating ear 401 drives the movable seat 402 to rotate, and then drives the connecting rod 403 to swing, so that the connecting rod 403 drives the second rotating ear 405 to rotate, and the rotation of the second rotating ear 405 drives the first connecting shaft 404 to rotate, so that the first connecting The shaft 404 drives the two swing arms 406 to swing, thereby driving the loading rack 407 to rotate. When the contact point between the movable seat 402 and the connecting rod 403 is close to the highest point, the loading rack 407 is rotated to the top of the aluminum single plate body 9. At this time, the multiple first suction cups 411 on the loading rack 407 are just in contact with the aluminum single plate body 9. At this time, the first air pump 413 is started, and the multiple first suction cups 411 are evacuated through the third connecting pipe 414 and the second connecting pipe 412, thereby sucking the aluminum single plate body 9. The first rotating shaft 301 continues to rotate, which drives the second rotating ear 405 to swing downward, thereby driving the two swing arms 406 to swing toward the die assembly 5 through the first connecting shaft 404, thereby driving the sucked aluminum single plate body 9 to be transported to the positioning groove 503 on the inclined surface of the polygonal bottom mold 502;

[0048] When the aluminum single plate body 9 is fitted into the positioning groove 503 on the inclined surface of the polygonal bottom mold 502, the second air pump 508 starts to work, and the second air pump 508 evacuates the connected multiple second suction cups 506 through the fifth connecting pipe 509 and the fourth connecting pipe 507, so that the multiple second suction cups 506 suck the fitted aluminum single plate body 9;

[0049] At this time, the rotation of the first rotating shaft 301 will also drive the first gear 701 to rotate, the rotation of the first gear 701 will drive the second gear 703 to rotate, the rotation of the second gear 703 will drive the third gear 705 to rotate, and then drive the second installation shaft 704 to rotate, so that the rotation of the second installation shaft 704 drives the rotating sleeve 706 to rotate, and the rotation of the rotating sleeve 706 drives the movable head 707 to rotate, and when the movable head 707 rotates to the adjacent notch 710, it drives the dividing plate 709 to rotate, and then drives the second rotating shaft 501 and the polygonal bottom mold 502 to rotate;

[0050] When the sucked aluminum veneer body 9 is rotated to the right below the pressing plate 607 through the polygonal bottom mold 502, the first rotating shaft 301 rotates to drive the multiple eccentric wheels 601 to rotate, so that the multiple eccentric wheels 601 rotate to squeeze the movable plate 602, so that the movable plate 602 squeezes the pressing plate 607 through the multiple connecting columns 606, so that the pressing plate 607 presses the aluminum veneer body 9. At this time, when the multiple eccentric wheels 601 continue to rotate, they drive the multiple punching needles 609 to punch the aluminum veneer body 9 and penetrate the corresponding through holes 610. The punched aluminum sheet falls into the connected discharge cavity 504 through the punching groove 505, completing the punching of the first aluminum veneer body 9;

[0051] When the first rotating shaft 301 continues to rotate, it drives the entire feeding mechanism 4 to reset, and continues to suck the aluminum single plate body 9 to be transported on the conveyor belt 202, and at the same time drives the polygonal bottom mold 502 to continue to rotate, so that the multiple second suction cups 506 at the bottom of the aluminum single plate body 9 stop pumping air after punching, so that the aluminum single plate body 9 falls onto the unloading rack 8 due to gravity, and the punching process is completed. At the same time, when the first rotating shaft 301 continues to rotate, it drives the multiple eccentric wheels 601 to continue to rotate, and the multiple first springs 605 drive the movable plate 602 to slowly reset, and then drive the multiple punching needles 609 to slowly reset, and at the same time, the multiple second springs 608 drive the pressure plate 607 to slowly reset, so as to punch the next aluminum single plate body 9.

[0052] 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.
