Description

Technical Field

[0001] The present invention relates to a stamping machine, and in particular to a stamping machine for aluminum profile production. Background Art

[0002] A stamping machine for aluminum profile production is a mechanical device specifically used for stamping aluminum bars into various specifications and shapes of aluminum profiles. It drives the upper die to move downward through a hydraulic cylinder to cooperate with the lower die, applying pressure to the aluminum bar placed between the two dies to cause plastic deformation, thereby achieving the required product shape.

[0003] However, some existing stamping machines for aluminum profile production have certain limitations. For example, during the aluminum profile forming process, it is necessary to manually take the aluminum bar to the lower die, and then start the stamping machine to stamp the aluminum bar. After the aluminum bar is stamped and formed, it is necessary to manually take out the stamping finished product 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

[0027] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0028] A stamping machine for aluminum profile production, as Figures 1 - 10As shown in the figure, it includes a base 1, a fixing 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 connecting member 7, a connecting frame 8, a storage box 801, a rotating frame 9, a gear 11, a rack 12 and a top-receiving linkage mechanism 17. On the right side of the top of the base 1, there is a fixing frame 2. The fixing frame 2 is composed of four cylindrical tubes and a square plate. The upper mold 3 is slidably connected to the fixing frame 2 and slides on the four cylindrical tubes of the fixing frame 2. Trapezoidal push rods 301 are connected to the four corners of the upper mold 3. In the middle of the top of the fixing frame 2, there is a hydraulic cylinder 5, and the push rod of the hydraulic cylinder 5 is connected to the upper mold 3. On the right side of the top of the base 1, there is a lower mold 4. Guide plates 6 are symmetrically arranged on the left and right sides of the top of the lower mold 4. The guide plates 6 slide on the lower mold 4. Pull rods 604 are symmetrically arranged in the front and back on the top of the two guide plates 6, and the pull rods 604 are all in contact with the trapezoidal push rods 301. The trapezoidal push rod 301 is composed of four round rods, and the bottom round rod is an inclined rod, and the inclined rod has a certain inclination angle with the horizontal plane. Racks 12 are arranged at the tops of the left pull rods 604. On the left side of the top of the base 1, there is a connecting frame 8. On the left side of the top of the connecting frame 8, there is a storage box 801 for storing aluminum rods to be processed, ensuring the supply of aluminum rod raw materials. The left side of the top of the connecting frame 8 is rotatably connected to a rotating frame 9. The rotating frame 9 is composed of a long rod and two discs. Arc-shaped notches are circumferentially spaced on the two discs, and the arc-shaped notches are used to receive aluminum rod raw materials. Gears 11 are arranged on the front and back sides of the rotating frame 9. The transmission mode between the gear 11 and the rotating frame 9 is one-way transmission, that is, a one-way bearing is provided between the gear 11 and the rotating frame 9. When the two guide plates 6 move away from each other, during the meshing process of the gear 11 and the rack 12, under the action of the one-way bearing, the rotating frame 9 remains stationary. When the two guide plates 6 move closer to each other, the gear 11 and the rack 12 mesh again, and at this time the gear 11 will drive the rotating frame 9 to rotate. On the rear side of the top of the base 1, there is a top-receiving linkage mechanism 17.

[0029] As Figures 8 - 10As shown in the figure, the top-receiving linkage mechanism 17 includes a top block 401, a second elastic member 402, a push plate 13, and a cylinder 15. Cylinders 15 are symmetrically arranged on the left and right at the rear side of the top end of the base 1. A push plate 13 is connected to the air rods of the two cylinders 15. An installation hole 403 is provided inside the lower die 4. The rear end and the top end of the lower die 4 communicate with the installation hole 403. Second elastic members 402 are arranged at intervals at the inner bottom end of the installation hole 403. The top ends of the second elastic members 402 are connected to a top block 401. The top rear end of the top block 401 abuts against the push plate 13. The top block 401 is installed in the installation hole 403. One end of the top block 401 is connected to a convex block, and an inclined surface is provided on the convex block. The inclined surface is used in cooperation with the push plate 13. When the cylinder 15 pushes the push plate 13 to move forward, at this time, the lower side part at the front end of the push plate 13 will no longer press the top block 401, and the second elastic member 402 changes from the compressed state to the relaxed state. Under the action of the second elastic member 402, the top block 401 moves upward and jacks up the die-cast aluminum rod. When the cylinder 15 pulls the push plate 13 to reset backward and the push plate 13 contacts the convex block again, the push plate 13 will make the top block 401 reset downward by pressing the inclined surface on the convex block. During this process, the second elastic member 402 also returns to the compressed state again.

[0030] As Figures 5 - 7 shown, it further includes a stop baffle 605 and a stop tube 10. The top end of the left guide plate 6 is connected to the stop baffle 605. The left end of the fixed frame 2 is connected to the stop tube 10. The lower end opening of the stop tube 10 is adapted to the stop baffle 605. The left end opening of the stop tube 10 is close to the rotary frame 9. When the aluminum rod on the rotary frame 9 falls onto the stop baffle 605 in the stop tube 10, at this time, the two guide plates 6 are approaching each other, and the stop baffle 605 is also moving away from the stop tube 10. The stop baffle 605 plays a limiting role on the aluminum rod to prevent the aluminum rod from falling onto the left guide plate 6 in advance and then rolling outside the stamping machine. 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 limit plates 601.

[0031] As Figure 3 and Figure 4 shown, it further includes limit plates 601 and a blocking plate 602. Limit plates 601 are symmetrically arranged at the front and rear of the top ends of the two guide plates 6. Rectangular notches 603 are opened at one end where the two guide plates 6 contact each other. The two rectangular notches 603 form a rectangular through hole. A channel is formed between the two limit plates 601, enabling the aluminum rod to roll into the rectangular through hole smoothly. A blocking plate 602 is provided near the rectangular notch 603 on the right guide plate 6. The blocking plate 602 blocks the aluminum rod coming from the left to prevent the aluminum rod from rolling out of the right guide plate 6 and then falling to the ground.

[0032] As Figures 1 - 4As shown in the figure, the connection includes a connecting rod 701, a first elastic member 702, and a connecting pipe 703. The bottom ends of the two guide plates 6 are symmetrically provided with connecting rods 701 at the front and rear. The left and right ends of the lower die 4 are symmetrically provided with connecting pipes 703 on the left and right. The connecting rod 701 is sleeved in the connecting pipe 703, and a first elastic member 702 is connected between the connecting rod 701 and the connecting pipe 703. Both the first elastic member 702 and the second elastic member 402 are springs.

[0033] As Figure 1 shown in the figure, it further includes a collection box 16 and a handle 1601. A collection box 16 is provided at the front side of the top end of the base 1. A handle 1601 is connected to the front end of the collection box 16. The collection box 16 is used to receive the aluminum materials that have completed stamping and forming. The handle 1601 facilitates the operator to carry and move the collection box 1.

[0034] As Figure 5 、 Figure 9 and Figure 10 shown in the figure, it further includes a guide frame 8011 and a demolding spray head 14. A guide frame 8011 is connected to the lower outlet of the storage box 801. The guide frame 8011 is composed of two short rods and two long rods. The lower sides of the two long rods both have a structure that bends upward and folds. 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 through 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, at the position of the structure where the two long rods bend upward and fold. The arc-shaped notch will receive the aluminum rod here and rotate to the top of the rotating frame 9. A demolding spray head 14 is provided on the push plate 13, and the top end of the demolding spray head 14 can be externally connected to a device storing demolding liquid.

[0035] Initially, place a circular aluminum rod at the rectangular through-hole formed by the two guide plates 6. Load a certain amount of aluminum rods into the storage box 801. Under the action of gravity, the aluminum rods in the storage box 801 will slide onto the guide frame 8011 and contact the rotating frame 9. Place an aluminum rod on the two arc-shaped notches on the upper side of the rotating frame 9. After starting the hydraulic cylinder 5, the push rod of the hydraulic cylinder 5 drives the upper die 3 to move downward. The trapezoidal push rods 301 at the four corners of the upper die 3 also descend and squeeze the pull rods 604. The trapezoidal push rods 301 force the pull rods 604 to drive the two guide plates 6 to move away from each other. The aluminum rod at the rectangular through-hole falls onto the lower die 4 and stays on the lower die 4. During the movement of the two guide plates 6, the connecting rod 701 follows the guide plate 6 to move, and the first elastic member 702 changes from the initial state to the stretched state. Initially, the inclined rod at the bottom end of the trapezoidal push rod 301 squeezes the pull rod 604. During this process, the rack 12 approaches the gear 11 and meshes with the gear 11. The gear 11 rotates, and the rotating frame 9 remains stationary. The stop baffle 605 approaches the stop pipe 10 and finally stays at the lower opening of the stop pipe 10 (For the state diagram of the stop baffle 605 close to the stop pipe 10, reference can be made toFigure 7 ), when the vertical round rod of the trapezoidal push rod 301 squeezes the pull rod 604, the two guide plates 6 are no longer away from each other, and the positions of the two guide plates 6 do not change. Figure 7 , the hydraulic cylinder 5 drives the upper mold 3 to continue to move downward, and finally the upper mold 3 contacts the lower mold 4 and extrude the aluminum rod. Then, the hydraulic cylinder 5 drives the upper mold 3 to continue to move upward. When the upper mold 3 moves upward a certain distance and the distance between the upper mold 3 and the lower mold 4 can accommodate the push plate 13 to pass through, the cylinder 15 is started, and the cylinder 15 gas rod pushes the push plate 13 forward. The push plate 13 no longer conflicts with the top block 401, and the second elastic member 402 pushes the top block 401 upward to push the formed aluminum part out of the lower mold 4. At this time, the top of the top block 401 is flush with the top of the lower mold 4, and the push plate 13 moves forward and pushes the aluminum part into the collection box 16. When the demolding nozzle 14 is located directly above the mounting hole 403, the demolding nozzle 14 sprays the demolding liquid into the mounting hole 403. Then, the cylinder 15 drives the push plate 13 to reset, and the top block 401 moves downward back to its original position. At the same time, the hydraulic cylinder 5 drives the upper mold 3 to continue When the left guide plate 6 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, causing the rotating frame 9 to rotate 90 degrees. The aluminum rod initially placed on the rotating frame 9 falls onto the stopping baffle 605 through the stopping tube 10, and the aluminum rod passes through the channel between the two limit plates 601 on the left guide plate 6 and rolls into the rectangular through hole. During the rotation of the rotating frame 9, the rotating frame 9 picks 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, stamp the aluminum rod, and push the stamped aluminum rod into the collection box 16.
