Description

Technical Field

[0001] The utility model belongs to the technical field of stamping machines, and particularly relates to an aluminum profile stamping machine. Background Art

[0002] Stamping is a forming process that applies external forces to sheets, strips, tubes, profiles, etc. by a press and a die, causing them to undergo plastic deformation or separation, so as to obtain workpieces (stamped parts) with the required shapes and dimensions. Stamping and forging both belong to plastic processing (or pressure processing).

[0003] Traditional stamping machines are provided with relevant protective structures. However, most of the downward pressure protection is to manually open and close the protective door or protective plate. Many workers often do not close the protective door or protective plate when operating the stamping machine in order to save time, and irreversible injuries are caused during the stamping process; if the aluminum profile is cut off and flies out during the stamping process, it is easy to cause injuries to the operators. Therefore, improvements are now made to an aluminum profile stamping machine. Summary of the Utility Model

Specific embodiments

[0024] As Figure 1 And Figure 3 And Figure 4As shown in the figure, an embodiment of the utility model provides an aluminum profile stamping machine, which includes a workbench 1. Support legs 2 are provided at the four corners of the bottom of the workbench 1. A horizontal plate 3 is connected to the outside of the support legs 2. A trolley 5 is slidably arranged at the bottom of the workbench 1. A support frame 7 is arranged at the top of the workbench 1. A stamping assembly is arranged inside the support frame 7. The stamping assembly includes a hydraulic cylinder 8 fixedly sleeved inside the support frame 7. Two limiting plates 11 are arranged inside the support frame 7. A first connecting block 13 and a second connecting block 29 are respectively slid on the opposite sides of the two limiting plates 11. A lower pressing plate 9 is fixedly connected between the first connecting block 13 and the second connecting block 29. A stamping head 10 is arranged at the bottom of the lower pressing plate 9. Movable blocks 14 are fixedly installed on the outside of the first connecting block 13 and the second connecting block 29 and the two limiting plates 11. First connecting rods 15 and second connecting rods 16 are respectively rotatably connected to the outside of the movable blocks 14. The centers of the outside of the first connecting rod 15 and the second connecting rod 16 are rotatably connected. The second connecting rod 16 is connected with a protective net 17.

[0025] As Figure 3 and Figure 5 shown in the figure, a blanking port is opened on the outside of the workbench 1. A guiding plate 18 is rotatably connected to the outside of the blanking port. An L-shaped fixing block 19 is installed at the bottom of the blanking port. A damping block 20 is installed at the top of the L-shaped fixing block 19. A damping spring 21 is arranged at the top of the damping block 20. The damping spring 21 is fixedly connected with the guiding plate 18. At this time, the aluminum profile on the stamping plate 30 falls from the guiding plate 18, so that the damping spring 21 and the guiding plate 18 cooperate with each other to offset the force when the aluminum profile falls, preventing the aluminum profile from being damaged when it falls.

[0026] As Figure 3 shown in the figure, a stamping plate 30 is installed at the center of the workbench 1. Stamping holes 26 are opened on the opposite sides of the stamping plate 30 and the workbench 1, so that the waste materials generated during stamping fall out from the stamping holes 26, which facilitates subsequent collection.

[0027] As Figure 6 shown in the figure, a first cylinder 22 is vertically installed on the workbench 1. The output shaft of the first cylinder 22 is fixedly connected with a U-shaped pushing plate 24. The U-shaped pushing plate 24 is slidably connected with the stamping plate 30. A pushing groove 23 is opened inside the U-shaped pushing plate 24. The pushing groove 23 fits the outer surface of the stamping plate 30. During the movement, the U-shaped pushing plate 24 slides along the sliding groove 25. Furthermore, when moving, the pushing groove 23 passes through the surface of the stamping plate 30 to push the aluminum profile on the stamping plate 30.

[0028] As Figure 2As shown in the figure, two second cylinders 27 are horizontally installed on the top of the workbench 1, and the output shafts of the two second cylinders 27 are fixedly connected with fixing plates 28. The aluminum profiles on the 30 are fixed through the fixing plates 28 to prevent the aluminum profiles from shifting when the punching head 10 punches the aluminum profiles.

[0029] As Figure 1 shown in the figure, a limiting frame 4 is provided on the top of the cross plate 3, and a limiting groove 6 is provided on one side of the trolley 5 close to the limiting frame 4. The limiting groove 6 is slidably connected with the limiting frame 4. Through the mutual cooperation between the limiting groove 6 and the limiting frame 4, the trolley 5 can move, which is convenient for the transportation of aluminum profile scraps.

[0030] As Figure 4 and Figure 6 shown in the figure, guide grooves 12 are formed on the opposite sides of the two limiting plates 11. The first connecting block 13 and the second connecting block 29 are slidably connected with the guide grooves 12 to improve the stability when the output shaft of the hydraulic cylinder 8 pushes the lower pressing plate 9 to move. A sliding groove 25 is formed inside the workbench 1, and the end of the U-shaped pushing plate 24 is slidably connected with the sliding groove 25 to improve the stability when the output shaft of the first cylinder 22 pushes the U-shaped pushing plate 24 to move, so that the U-shaped pushing plate 24 can smoothly push the aluminum profiles on the 30.

[0031] Working principle:

[0032] The operator places the aluminum profile to be stamped on the stamping plate 30. Subsequently, by connecting to an external power source, the output shaft of the second cylinder 27 pushes the fixed plate 28 towards the stamping plate 30, so that the fixed plate 28 fixes the corners of the aluminum profile. Then, the hydraulic cylinder 8 is started, and the output shaft of the hydraulic cylinder 8 drives the lower pressing plate 9 to move. Further, the lower pressing plate 9 slides downward inside the guiding groove 12 through the first connecting block 13 and the second connecting block 29. During the downward sliding process, it drives the first connecting rod 15 to rotate. Furthermore, when the first connecting rod 15 rotates, it pushes the connected second connecting rod 16 to rotate, and then drives the protective net 17 fixed on the second connecting rod 16 to rotate synchronously to the left. At this time, the stamping head 10 contacts the aluminum profile on the stamping plate 30, effectively protecting the aluminum profile during the stamping process, saving the stamping time and avoiding irreparable harm to personnel. The waste materials fall into the inside of the trolley 5 through the punching holes 26 for collection. At this time, the output shaft of the hydraulic cylinder 8 drives the lower pressing plate 9 to move upward, and then the first connecting rod 15 pulls the second connecting rod 16 to fold the protective net 17 on the second connecting rod 16, thus completing a stamping process. At this time, the output shaft of the first cylinder 22 drives the U-shaped pushing plate 24 to move. During the movement, the U-shaped pushing plate 24 slides along the sliding groove 25. Furthermore, when moving, the pushing groove 23 passes through the surface of the stamping plate 30. At this time, the aluminum profile on the stamping plate 30 falls from the guiding plate 18. The shock-absorbing spring 21 and the guiding plate 18 cooperate with each other to offset the force when the aluminum profile falls, preventing the aluminum profile from being damaged when falling.
