Description

Technical Field

[0001] The present invention relates to the technical field of molds, and more particularly to a processing mold for aluminum profiles. Background Art

[0002] A mold is a forming tool used in industrial production for processes such as injection molding, blow molding, extrusion, die casting, forging, etc. Its core function is to process a blank into a product with a specific shape and size through changes in physical state (such as melting, cooling, stamping, etc.); when processing aluminum profiles, a mold is used.

[0003] In the existing processing mold, the buffer structure has been improved. After improvement, it can achieve the adjustment of the buffer force and can automatically lock after adjustment. Specifically as follows: First, since the head end and the tail end of the elastic member are respectively in contact with the stamping seat and the adjusting plate, and the limit sliding rod, the adjusting plate, and the elastic member together form the elastic shock absorption structure of the stamping seat, the stamping impact force of the stamping seat can be alleviated.

[0004] However, in the actual processing process, an aluminum plate is placed on the stamping seat for stamping processing. After processing, the processed aluminum profile needs to be removed from the stamping seat. And when removing, since the aluminum profile is squeezed and clamped in the stamping seat, it is rather troublesome to remove the aluminum profile. When continuing the processing, it is necessary to place the aluminum profile on the stamping seat again for continuous processing. Such operation is time-consuming and laborious, reducing the work efficiency. Summary of the Invention

[0029] The following further elaborates on the present invention in conjunction with the attached Figures 1 - 8 drawings.

[0030] Refer to Figures 1 - 8, an embodiment of the present invention discloses a processing die for aluminum profiles, including a workbench 1 and a stamping seat 2. A blanking groove 21 is opened in the middle of the upper surface of the workbench 1. Two stamping seats 2 are arranged above the blanking groove 21 on the upper surface of the workbench 1 through a first moving structure. A first placement groove 3 is opened at the upper edge of each stamping seat 2. A feeding plate 26 is arranged at the rear side of the upper surface of the workbench 1 through a second moving structure. A second placement groove 27 is opened at the front side of the upper surface of the feeding plate 26. A driving structure is arranged between the stamping seat 2 and the first moving structure. A collecting structure is arranged in the middle of the lower surface of the workbench 1. A stockpiling structure is arranged on the left side of the workbench 1 near the feeding plate 26;

[0031] The driving structure includes four groups of convex blocks 4 respectively arranged on the mutually remote side surfaces of the two stamping seats 2. A vertical rod 5 is connected between each group of two convex blocks 4. A switching bar 6 is movably sleeved on each group of two vertical rods 5. A switching structure is arranged between the switching bar 6 and the workbench 1. A fixing bar 7 is connected to the rear end surface of the switching bar 6. The fixing bar 7 is in a U shape. Plug rods 8 are fixedly passed through both ends of the fixing bar 7. Two groups of connecting rods 13 are respectively fixedly connected to the left and right sides of the rear side surface of the workbench 1. A vertical plate 12 is movably sleeved on each group of two connecting rods 13. A blocking bar 11 is connected to the end of each group of two connecting rods 13 away from the workbench 1. A driving plate 9 is connected to the upper surface of the vertical plate 12. A first driving groove 10 is opened on the upper surface of the driving plate 9. A second driving groove 14 is opened on the lower surface of the driving plate 9;

[0032] A shielding edge 41 is connected to the rear edge of the upper surface of the stamping seat 2. A through groove 42 is opened below the shielding edge 41;

[0033] The second moving structure includes a longitudinal groove 23 opened in the middle of the rear side of the upper surface of the workbench 1. A first fixing rod 24 is connected between the two end walls of the longitudinal groove 23. A second moving block 25 is slidably arranged in the longitudinal groove 23. The bottom end of the feeding plate 26 is fixedly connected to the second moving block 25. The second moving block 25 is connected to the driving plate 9 through a connecting bar;

[0034] The first moving structure includes transverse grooves 20 opened on the upper surface of the workbench 1 at the front and rear sides of the stamping seat 2. Bottom blocks 15 are connected to the left and right side surfaces of the workbench 1 near both ends of each transverse groove 2 ten. A bidirectional screw rod 16 is rotatably connected between the two front bottom blocks 15. A cross bar is connected between the two rear bottom blocks 15. The thread directions of the left and right two sections on the bidirectional screw rod 16 are opposite. Two first moving blocks 18 are movably sleeved on the bidirectional screw rod 16 and the cross bar near the middle respectively. Thread grooves for the bidirectional screw rod 16 to pass through are opened on the two front first moving blocks 18. Through holes for the cross bar to pass through are opened on the two rear first moving blocks 18. A moving plate 19 is connected to the middle of the upper surface of each first moving block 18. The moving plate 19 movably passes through the transverse groove 20. The top end of the moving plate 19 is fastened to the stamping seat 2 by screws. A motor 17 is installed on one of the front bottom blocks 15. The output shaft of the motor 17 is connected to one end of the bidirectional screw rod 16;

[0035] The collection structure includes a collection box 22 arranged directly below the blanking chute 21. Connecting plates 28 are connected to the middle of the front and rear sides of the upper surface of the collection box 22. The upper ends of the connecting plates 28 pass through a hanging rod 29 movably. Side plates 30 are movably sleeved on both ends of the hanging rod 29. The top end of each side plate 30 is connected to the workbench 1.

[0036] The switching structure includes a through groove 34 opened in the middle of the left and right sides of the workbench 1. Guide strips 35 are provided on the front and rear side walls of the through groove 34. The guide strips 35 are in the shape of a parallelogram. A bottom plate 32 is inserted into the through groove 34 near the punching seat 2. The bottom end of the bottom plate 32 fixedly passes through the second fixing rod 33. The front and rear ends of the second fixing rod 33 are attached to the two side walls of the through groove 34. The top end of the bottom plate 32 is connected to the middle of the lower surface of the switching bar 6. Two springs 31 are sleeved on each vertical rod 5. The two ends of each spring 31 are respectively connected to the switching bar 6 and the convex block 4. After the aluminum profiles are punched in the two punching seats 2, the motor 17 is started to drive the bidirectional screw rod 16 to rotate. The two first moving blocks 18 move synchronously in opposite directions on the rotating bidirectional screw rod 16. The moving plate 19 is used to drive the two punching seats 2 to move, so as to open the two punching seats 2, so that the processed aluminum profiles in the punching seats 2 can directly fall from the blanking groove 21 into the collection box 22 for blanking and collection. And during the process of the two punching seats 2 moving away from each other, the punching seat 2 drives the bottom plate 32 on the switching bar 6 to move. The end of the second fixing rod 33 on the bottom plate 32 presses one inclined surface of the guide strip 35. The bottom plate 32 pulls the switching bar 6 to move downward on the vertical rod 5, driving the spring 31 to deform. And the downward movement of the switching bar 6 on the vertical rod 5 drives the insertion rod 8 at the upper end of the fixed strip 7 to move downward and insert into the first driving groove 10. In this way, when the two punching seats 2 are completely separated and the punching seats 2 continue to move, the end of the insertion rod 8 can be driven to press the groove wall of the first driving groove 10, so as to drive the driving plate 9 to move on the connecting rod 13. The connecting strip drives the second moving block 25 to move on the first fixing rod 24, so as to drive the feeding plate 26 to move toward the blanking groove 21. When the feeding plate 26 completely moves to directly above the blanking groove 21, the second fixing rod 33 on the bottom plate 32 moves to the other end of the guide strip 35. Under the elastic force of the spring 31, the switching bar 6 and the second fixing rod 33 as a whole move upward and reset. At this time, the motor 17 drives the bidirectional screw rod 16 to rotate in the reverse direction. The first moving block 18 drives the two punching seats 2 to move toward each other. Using the guiding effect of the other inclined surface of the guide strip 35 on the second fixing rod 33, the punching seat 2 drives the second fixing rod 33 to slide along the upper surface of the guide strip 35, pushing the switching bar 6 to move upward on the vertical rod 5, so as to drive the insertion rod 8 at the lower end of the fixed strip 7 to move upward and insert into the second driving groove 14. In this way, when the two punching seats move to the feeding plate 26 to support the aluminum profile, by the extrusion of the insertion rod 8 on the groove wall of the second driving groove 14, the driving plate 9 is pushed to move in the reverse direction and reset, and the feeding plate 26 is driven to move in the reverse direction. Using the shielding of the shielding edge 41 on the punching seat 2 for the aluminum profile, when the feeding plate 26 moves in the reverse direction, the aluminum profile still stays in the first placement groove 3 on the punching seat 2. After the two punching seats 2 are completely spliced, the processing work of the aluminum profile can be continued.

[0037] See Figure 1 andFigure 2 , the stock storage structure includes a storage plate 36 connected to the left side surface of the workbench 1 near the loading plate 26. A storage frame 37 is arranged on the storage plate 36. Feeding openings 38 are formed at the lower parts of the left and right side surfaces of the storage frame 37. A pushing structure is arranged on the loading plate 26;

[0038] The pushing structure includes a cylinder 39 installed at the lower part of the left side surface of the storage plate 36. One end of the output shaft of the cylinder 39 is connected to a pushing plate 40. The pushing plate 40 is inserted into the left feeding opening 38. During feeding, the cylinder 39 is started to drive the pushing plate 40 to move, and the pushing plate 40 pushes the aluminum profiles in the storage frame 37 onto the loading plate 26 to perform automatic feeding work.

[0039] The implementation principle of a processing die for aluminum profiles in an embodiment of the present invention is as follows: First, start the air cylinder 39 to drive the pushing plate 40 to move. The pushing plate 40 pushes the aluminum profiles in the storage frame 37 onto the loading plate 26. Then, start the motor 17 to drive the bidirectional screw 16 to rotate. The two first moving blocks 18 move synchronously in opposite directions on the rotating bidirectional screw 16, and drive the two stamping seats 2 to move through the moving plate 19, thereby opening the two stamping seats 2, so that the processed aluminum profiles in the stamping seats 2 can directly fall from the blanking groove 21 into the collection frame 22 for blanking and collection. Moreover, during the process of the two stamping seats 2 moving away from each other, the stamping seats 2 drive the bottom plate 32 on the switching bar 6 to move. The end of the second fixed rod 33 on the bottom plate 32 presses one inclined surface of one end of the guiding bar 35. The bottom plate 32 pulls the switching bar 6 to move downward on the vertical rod 5, causing the spring 31 to deform. And the downward movement of the switching bar 6 on the vertical rod 5 drives the insertion rod 8 at the upper end of the fixed bar 7 to move downward and insert into the first driving groove 10. In this way, when the two stamping seats 2 are completely separated and continue to move, the end of the insertion rod 8 can be driven to press the groove wall of the first driving groove 10, thereby driving the driving plate 9 to move on the connecting rod 13, driving the second moving block 25 to move on the first fixed rod 24 through the connecting bar, and thus driving the loading plate 26 to move toward the blanking groove 21. When the loading plate 26 completely moves to directly above the blanking groove 21, the second fixed rod 33 on the bottom plate 32 moves to the other end of the guiding bar 35. Under the elastic force of the spring 31, the switching bar 6 and the second fixed rod 33 as a whole move upward and reset. At this time, the motor 17 drives the bidirectional screw 16 to rotate in the reverse direction. The first moving block 18 drives the two stamping seats 2 to move toward each other. By using the guiding effect of the inclined surface at the other end of the guiding bar 35 on the second fixed rod 33, the stamping seats 2 drive the second fixed rod 33 to slide along the upper surface of the guiding bar 35, pushing the switching bar 6 to move upward on the vertical rod 5, thereby driving the insertion rod 8 at the lower end of the fixed bar 7 to move upward and insert into the second driving groove 14. In this way, when the two stamping seats 2 move to the loading plate 26 to support the aluminum profiles, by using the extrusion of the insertion rod 8 on the groove wall of the second driving groove 14, the driving plate 9 is pushed to move in the reverse direction and reset, and the loading plate 26 is driven to move in the reverse direction. By using the shielding edge 41 on the stamping seat 2 to shield the aluminum profiles, when the loading plate 26 moves in the reverse direction, the aluminum profiles still stay in the first placement groove 3 on the stamping seat 2. After the two stamping seats 2 are completely spliced, the processing work of the aluminum profiles can continue, and the working efficiency is higher.

[0040] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
