Description

Technical Field

[0001] This invention relates to a stamping machine, and more particularly to a stamping machine for producing aluminum profiles. Background Technology

[0002] A stamping press for aluminum profile production is a type of mechanical equipment specifically used to stamp aluminum bars into various specifications and shapes. It uses a hydraulic cylinder to drive an upper die downwards to engage with a lower die, applying pressure to the aluminum bar placed between the two dies, causing it to undergo plastic deformation and achieve the desired product shape.

[0003] However, some existing stamping machines used in aluminum profile production have certain limitations. For example, during the aluminum profile forming process, the aluminum rod needs to be manually lifted onto the lower die before the stamping machine is started to stamp the rod. After the rod is formed, it needs to be manually removed again. This series of operations not only increases the labor intensity of workers but also affects the production efficiency of aluminum materials. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing stamping machines for aluminum profile production mentioned above, which have low automation, the purpose of this invention is to provide a stamping machine for aluminum profile production.

[0005] The technical solution of the present invention is as follows: a stamping machine for producing aluminum profiles, comprising a base, a fixed frame, an upper die, a trapezoidal push rod, a lower die, a hydraulic cylinder, a guide plate, a tie rod, a connector, a connecting frame, a storage box, a rotating frame, gears, a rack, and a top-and-retract linkage mechanism. A fixed frame is provided on the right side of the top of the base, and the upper die is slidably connected to the fixed frame. Trapezoidal push rods are connected to the four corners of the upper die. A hydraulic cylinder is provided in the middle of the top of the fixed frame, and the push rod of the hydraulic cylinder is connected to the upper die. A lower die is provided on the right side of the top of the base. Guide plates are symmetrically arranged on the left and right sides of the top of the lower die. Tie rods are symmetrically arranged on the top of both guide plates, and the tie rods are in contact with the trapezoidal push rods. A rack is provided on the top of the left tie rod. A connecting frame is connected to the left side of the top of the base. A storage box is connected to the left side of the top of the connecting frame. A rotating frame is rotatably connected to the left side of the top of the connecting frame. Gears are provided on both the front and rear sides of the rotating frame, and the gears can mesh with the rack. A top-and-retract linkage mechanism is provided on the rear side of the top of the base.

[0006] In a preferred embodiment of the present invention, the top-retracting linkage mechanism includes a top block, a second elastic element, a push plate, and a cylinder. Cylinders are symmetrically arranged on the left and right sides of the rear top of the base. The push plate is connected to the air rods of the two cylinders. The lower mold has an installation hole inside. The rear end and the top of the lower mold are connected to the installation hole. The bottom inner end of the installation hole is provided with a second elastic element at intervals. The top of the second elastic element is connected to the top block. The rear top of the top block abuts against the push plate.

[0007] In a preferred embodiment of the present invention, a stopping baffle and a stopping tube are also included. The top end of the left guide plate is connected to the stopping baffle, and the left end of the fixing frame is connected to the stopping tube. The lower end opening of the stopping tube is adapted to the stopping baffle, and the left end opening of the stopping tube is close to the rotating frame.

[0008] In a preferred embodiment of the present invention, a limiting plate is also included. The top ends of the two guide plates are symmetrically provided with limiting plates. The ends of the two guide plates that are in contact with each other are provided with rectangular notches. The two rectangular notches are combined to form a rectangular through hole.

[0009] In a preferred embodiment of the present invention, a baffle plate is also included, wherein the baffle plate is provided near the rectangular notch on the right guide plate.

[0010] In a preferred embodiment of the present invention, the connector includes a connecting rod, a first elastic element, and a connecting tube. The connecting rods are symmetrically arranged at the bottom ends of the two guide plates, and the connecting tubes are symmetrically arranged at the left and right ends of the lower mold. The connecting rod is sleeved inside the connecting tube, and the first elastic element connects the connecting rod and the connecting tube.

[0011] In a preferred embodiment of the present invention, a collection box and a handle are also included. The collection box is provided on the front side of the top of the base, and the handle is connected to the front end of the collection box.

[0012] In a preferred embodiment of the present invention, a guide frame is also included. The guide frame is connected to the lower outlet of the storage box. The guide frame is composed of two short rods and two long rods. The lower side of the two long rods has a curved and upward folding structure.

The transmission method between the gear and the rotating frame is unidirectional transmission.

[0014] In a preferred embodiment of the present invention, a demolding nozzle is also included, and the demolding nozzle is provided on the push plate.

[0015] The beneficial effects of this invention are as follows: the rotating frame is driven to rotate by the meshing of gears and racks, transferring aluminum rods from the storage box to the guide plate, and then falling into the rectangular through hole through the channel between the two limiting plates, thus realizing automatic feeding of aluminum rods. The invention is designed with a top-and-collection linkage mechanism, in which the top block pushes the stamped aluminum material out of the lower mold, and the push plate pushes the formed aluminum material into the collection box, realizing the integrated operation of aluminum material stamping, ejection and collection, reducing manual intervention, improving production efficiency, effectively solving the problem of frequent manual intervention required by existing equipment, significantly improving production efficiency and reducing the labor intensity of workers.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] A stamping machine for producing aluminum profiles, such as Figures 1-10As shown, the system includes a base 1, a fixed frame 2, an upper mold 3, a trapezoidal push rod 301, a lower mold 4, a hydraulic cylinder 5, a guide plate 6, a pull rod 604, a connector 7, a connecting frame 8, a storage box 801, a rotating frame 9, a gear 11, a rack 12, and a top-and-retract linkage mechanism. The fixed frame 2 is located on the top right side of the base 1. The fixed frame 2 consists of four cylindrical tubes and a square plate. The upper mold 3 is slidably connected to the fixed frame 2, and slides on the four cylindrical tubes of the fixed frame 2. Trapezoidal push rods 301 are connected to each of the four corners of the base 1. A hydraulic cylinder 5 is located at the top center of the fixed frame 2. The push rod of the hydraulic cylinder 5 is connected to the upper mold 3. A lower mold 4 is located on the right side of the top of the base 1. Guide plates 6 are symmetrically arranged on the top of the lower mold 4. The guide plates 6 slide on the lower mold 4. Pull rods 604 are symmetrically arranged at the top of the two guide plates 6. The pull rods 604 are in contact with the trapezoidal push rods 301. The trapezoidal push rods 301 are composed of four round rods, and the round rods at the bottom are inclined rods. The horizontal surface has a certain angle of inclination. The top of the left tie rod 604 is equipped with a rack 12. The top left of the base 1 is connected to a connecting frame 8. The top left of the connecting frame 8 is connected to a storage box 801. The storage box 801 is used to store aluminum rods to be processed, ensuring the supply of aluminum rod raw materials. The top left of the connecting frame 8 is rotatably connected to a rotating frame 9. The rotating frame 9 consists of a long rod and two discs. The two discs have arc-shaped notches spaced circumferentially. The arc-shaped notches are used to receive aluminum rod raw materials. Gears 11 are provided on both the front and rear sides of the rotating frame 9. The transmission method between the gears 11 and the rotating frame 9 is unidirectional transmission. That is, there is a one-way bearing between the gears 11 and the rotating frame 9. When the two guide plates 6 are far apart, the gears 11 and rack 12 mesh with each other. Under the action of the one-way bearing, the rotating frame 9 remains stationary. When the two guide plates 6 are close together, the gears 11 and rack 12 mesh again. At this time, the gears 11 will drive the rotating frame 9 to rotate. The top rear side of the base 1 is equipped with a top-retraction linkage mechanism.

[0029] like Figures 8-10As shown, the top-retracting linkage mechanism includes a top block 401, a second elastic element 402, a push plate 13, and a cylinder 15. Cylinders 15 are symmetrically arranged on the rear side of the top of the base 1. Push plates 13 are connected to the air rods of the two cylinders 15. The lower mold 4 has mounting holes 403 inside. The rear end and top end of the lower mold 4 communicate with the mounting holes 403. Second elastic elements 402 are spaced apart at the bottom inner end of the mounting holes 403. The top of the second elastic element 402 is connected to the top of the second elastic element 402. The rear top of the top block 401 abuts against the push plate 13. The top block 401 is installed in the mounting hole 403. One end of the top block 401 is connected to... The protrusion has a bevel, which works in conjunction with the push plate 13. When the cylinder 15 pushes the push plate 13 forward, the lower part of the front end of the push plate 13 will no longer press the top block 401. The second elastic element 402 changes from a compressed state to a relaxed state. Under the action of the second elastic element 402, the top block 401 moves upward and lifts the die-cast aluminum rod. When the cylinder 15 pulls the push plate 13 back to its original position, and the push plate 13 contacts the protrusion again, the push plate 13 will press the bevel on the protrusion to make the top block 401 return to its original position downward. During this process, the second elastic element 402 also returns to a compressed state.

[0030] like Figures 5-7 As shown, it also includes a stop baffle 605 and a stop tube 10. The top of the left guide plate 6 is connected to the stop baffle 605, and the left end of the fixing frame 2 is connected to the stop tube 10. The lower opening of the stop tube 10 is adapted to the stop baffle 605. The left opening of the stop tube 10 is close to the rotating frame 9. When the aluminum rod on the rotating frame 9 falls onto the stop baffle 605 in the stop tube 10, the two guide plates 6 are moving closer to each other, and the stop baffle 605 is also moving away from the stop tube 10. The stop baffle 605 restricts the aluminum rod and prevents it from falling onto the left guide plate 6 in advance, thus rolling out of the press. When the stop baffle 605 no longer blocks the aluminum rod, the aluminum rod falls onto the left guide plate 6 and rolls into the rectangular through hole through the channel between the two limiting plates 601.

[0031] like Figure 3 and Figure 4 As shown, it also includes a limiting plate 601 and a blocking plate 602. The tops of the two guide plates 6 are symmetrically provided with limiting plates 601. The ends of the two guide plates 6 that are in contact with each other are provided with rectangular notches 603. The two rectangular notches 603 are combined to form a rectangular through hole. A channel is formed between the two limiting plates 601, so that the aluminum rod can roll smoothly into the rectangular through hole. The right guide plate 6 is provided with a blocking plate 602 near the rectangular notch 603. The blocking plate 602 blocks the aluminum rod from the left side to prevent the aluminum rod from rolling out of the right guide plate 6 and falling to the ground.

[0032] like Figures 1-4As shown, the connector 7 includes a connecting rod 701, a first elastic element 702, and a connecting tube 703. The connecting rods 701 are symmetrically arranged at the bottom ends of the two guide plates 6. The connecting tubes 703 are symmetrically arranged at the left and right ends of the lower mold 4. The connecting rods 701 are sleeved inside the connecting tubes 703. The first elastic element 702 is connected between the connecting rods 701 and the connecting tubes 703. Both the first elastic element 702 and the second elastic element 402 are springs.

[0033] like Figure 1 As shown, it also includes a collection box 16 and a handle 1601. The collection box 16 is provided on the front side of the top of the base 1. The handle 1601 is connected to the front end of the collection box 16. The collection box 16 is used to receive aluminum materials that have been stamped and formed. The handle 1601 makes it convenient for operators to carry and move the collection box 1.

[0034] like Figure 5 , Figure 9 and Figure 10 As shown, it also includes a guide frame 8011 and a stripping nozzle 14. The guide frame 8011 is connected to the lower outlet of the storage tank 801. The guide frame 8011 is composed of two short rods and two long rods. The lower side of the two long rods has a curved upward folding structure. When the rotating frame 9 rotates, the arc-shaped notch on the left side of the rotating frame 9 will rotate to the top. When the arc-shaped notch passes the guide frame 8011, the aluminum rod will fall from the upper part of the guide frame 8011 to the lower part of the guide frame 8011, located at the curved upward folding structure of the two long rods. The arc-shaped notch will receive the aluminum rod here and rotate to the top of the rotating frame 9. The push plate 13 is provided with a stripping nozzle 14. The top of the stripping nozzle 14 can be externally connected to a device storing stripping liquid.

[0035] Initially, a round aluminum rod is placed in the rectangular through-hole formed by the two guide plates 6. A certain amount of aluminum rods are loaded into the storage box 801. Under the action of gravity, the aluminum rods in the storage box 801 will slide down onto the guide frame 8011 and come into contact with the rotating frame 9. An aluminum rod is placed on the two arc-shaped notches on the upper side of the rotating frame 9. After the hydraulic cylinder 5 is activated, the push rod of the hydraulic cylinder 5 drives the upper mold 3 to move downward. The trapezoidal push rods 301 on the four corners of the upper mold 3 descend accordingly and squeeze the pull rod 604. The trapezoidal push rods 301 force the pull rod 604 to move the two guide plates 6 away from each other, and the rectangular through-hole... The aluminum rod falls onto the lower mold 4 and remains there. As the two guide plates 6 move, the connecting rod 701 moves with the guide plates 6. The first elastic element 702 changes from its initial state to a stretched state. Initially, the inclined rod at the bottom of the trapezoidal push rod 301 presses against the pull rod 604. During this process, the rack 12 approaches the gear 11 and meshes with it. The gear 11 rotates, the rotating frame 9 remains stationary, and the stopping baffle 605 approaches the stopping tube 10 and finally stops at the lower opening of the stopping tube 10 (see the diagram of the stopping baffle 605 close to the stopping tube 10 for reference). Figure 7 During the process of the trapezoidal push rod 301 pressing the vertical round rod against the pull rod 604, the two guide plates 6 do not move away from each other, and the positions of the two guide plates 6 do not change. (Refer to...) Figure 7 Hydraulic cylinder 5 drives upper mold 3 to continue moving downwards until it contacts lower mold 4, extruding the aluminum rod. Then, hydraulic cylinder 5 drives upper mold 3 to continue moving upwards. When upper mold 3 moves upwards a certain distance, and the distance between upper mold 3 and lower mold 4 is sufficient to allow push plate 13 to pass through, cylinder 15 is activated. The air rod of cylinder 15 pushes push plate 13 forward, and push plate 13 no longer contacts top block 401. Second elastic element 402 pushes top block 401 upwards, ejecting the formed aluminum part from lower mold 4. At this time, the top of top block 401 is flush with the top of lower mold 4. Push plate 13 moves forward and pushes the aluminum part into collection box 16. When demolding nozzle 14 is directly above mounting hole 403, demolding nozzle 14 sprays demolding liquid into mounting hole 403. Then, cylinder 15 drives push plate 13 to reset, and top block 401 moves downwards back to its original position. At the same time, hydraulic cylinder 5 drives upper mold 3 to continue moving upwards. As the push rod in the trapezoidal push rod 301 moves upward, the first elastic element 702 gradually resets when the pressing rod changes from a vertical rod to an inclined rod. The first elastic element 702 pulls the connecting rod 701 and the guide plate 6 on it to move, so that the two guide plates 6 move closer to each other and eventually return to the initial position. When the guide plate 6 on the left side starts to move, the rack 12 at the top of the left pull rod 604 meshes with the gear 11 on the rotating frame 9 again, so that the rotating frame 9 rotates 90 degrees. The aluminum rod initially placed on the rotating frame 9 falls onto the stop baffle 605 through the stop tube 10. The aluminum rod rolls into the rectangular through hole through the channel between the two limit plates 601 on the left guide plate 6. During the rotation of the rotating frame 9, the rotating frame 9 lifts up an aluminum rod on the guide frame 8011 and rotates it to the top of the rotating frame 9. After that, the equipment will repeat the above operation to stamp the aluminum rod and push the stamped aluminum rod into the collection box 16.
