Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy die casting equipment, and in particular to a novel fully automatic straightening and shaping machine for aluminum alloy die castings. Background Technology

[0002] In aluminum alloy die casting, the product deforms during the process of cooling from a hot to a cold state, making it impossible to achieve the ideal dimensions. Special forming fixtures are used in the manufacturing process to physically shape the product, ensuring it reaches the desired size.

[0003] Traditional forming methods rely on manual pressing, which is prone to errors due to inconsistent pressure, leading to product scrap and rising labor costs. This inefficiency results in products lacking competitiveness. To address these issues, we propose a novel fully automated straightening and forming machine for aluminum alloy die castings. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a new type of fully automatic straightening and shaping machine for aluminum alloy die castings, which reduces the shaping cycle time of die casting products, reduces the input of personnel, improves the automation level of the entire shaping process, improves production efficiency, improves product yield, ensures the safety of employees, and saves the company's production costs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a novel fully automatic straightening and shaping machine for aluminum alloy die castings, comprising a frame, a support fixed inside the frame, and a pressure plate platform fixed at the center of the support, including: a shaping mechanism fixed on the pressure plate platform, a pneumatic module fixed on the top of the frame to servo-correspond to the shaping mechanism, the shaping mechanism including a cuboid enclosure, shaping blocks, and positioning columns, the top of the enclosure being hollowed out and slides fixed at both ends of the hollowed-out inner wall, the shaping blocks including two symmetrical about the center of the enclosure, the two shaping blocks being slidably connected at one end to two... On the slide platform, the outer edge of the other pair of ends is spaced apart from the inner wall of the enclosure. The two shaping blocks have an inclined slope on their opposite side, and the slope structure corresponds to the structure of the external workpiece. The positioning column includes two columns, which are respectively located at the center of the gap between the ends of the two shaping blocks. Each positioning column has a vertically fixed sliding column at both ends. Each shaping block is slidably connected to the sliding column and is fitted with a first return spring in the same position. The pneumatic module is used to pneumatically press down the top of the workpiece. The pressure plate platform also has a vertically sliding top rod at the bottom of the corresponding external workpiece. The outer wall of the top rod is fitted with a second return spring for axial return.

[0006] Furthermore, the pneumatic module includes a servo cylinder, a sliding guide rod, and a lower pressure plate. The servo cylinder is fixed to the top of the frame, and its output end is axially limited by the sliding guide rod and fixedly connected to the lower pressure plate at the output end. The lower pressure plate has four symmetrically fixed first limiting posts at its bottom corners, and a second limiting post is fixed to the outside of one pair of the first limiting posts. The pressure plate platform has a third limiting post vertically fixed at the corresponding first and second limiting posts.

[0007] Fourth limit post.

[0008] Furthermore, when the bottom surface of the lower pressure plate contacts the top of the external workpiece, the second limiting post connects with the fourth limiting post. When the external workpiece is pressed down to the maximum depth, the fourth limiting post is embedded in the second limiting post, and simultaneously the first limiting post and the third limiting post come into contact.

[0009] Furthermore, an adjusting column is vertically fixed on the pressure plate platform, and multiple adjusting blocks are sleeved on the adjusting column. Each adjusting block can be movably fixed on the top of the third limiting column to match different types of external workpieces.

[0010] Furthermore, the two shaping blocks are fixed with a fixing plate on their opposite sides, and multiple nylon blocks are evenly distributed on the outer side of the fixing plate to contact the enclosure.

[0011] Furthermore, fixing blocks are fixed to the outer sides of the two slides to connect and fix them to the surrounding plate.

[0012] Furthermore, the frame has an opening on one side and a laser safety device is installed at the opening.

[0013] Furthermore, the frame integrates an electrical cabinet on one side of its opening, and a workbench is fixed below the electrical cabinet.

[0014] Furthermore, a forklift opening is provided at the bottom of the frame.

[0015] Compared with the prior art, the beneficial effects of this utility model include:

[0016] The pneumatic module drives the lower pressure plate to press down the workpiece, providing the necessary external driving force. After the workpiece is pressed down, the two shaping blocks can be pushed synchronously on the slide table by the slope to slide relative to each other, with the stroke controlled within 8.5mm. The back of the shaping block is connected to a nylon block by a fixing plate to contact the surrounding plate. After the workpiece is removed, the shaping block can be reset by the sliding column on the positioning column and the first return spring. Similarly, the top rod placed in the center of the pressure plate platform can also support the bottom of the workpiece and reset by the second return spring for the workpiece to be removed. The shaping process is the squeezing effect of the two shaping blocks on one side of the workpiece's outer edge. The overall squeezing and shaping process is stable and reliable, and is not easy to cause wear on the workpiece surface. Attached Figure Description

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] According to one embodiment of the present invention, in conjunction with Figures 1-4 As shown.

[0026] In this embodiment, a novel fully automatic straightening and shaping machine for aluminum alloy die castings includes a frame 1. A support 2 is fixed inside the frame 1, and a pressure plate platform 3 is fixed at the center of the support 2. The machine includes a shaping mechanism fixed on the pressure plate platform 3. A pneumatic module 4 is fixed to the top of the frame 1 to servo-correspond with the shaping mechanism. The shaping mechanism includes a cuboid enclosure 5, shaping blocks 6, and positioning columns 7. The top of the enclosure 5 is hollowed out, and slides 8 are fixed at both ends of the hollowed-out inner wall. Two shaping blocks 6 are included and are symmetrical about the center of the enclosure 5. One end of each of the two shaping blocks 6 is slidably connected to one of the two slides 8. The outer edge of the opposite end is spaced apart from the inner wall of the enclosure 5. The two shaping blocks 6 have an inclined slope 9 recessed on their opposite side, and the structure of the slope 9 corresponds to the structure of the external workpiece. The positioning post 7 includes two and is located at the center of the gap between the ends of the two shaping blocks 6. Each positioning post 7 has a sliding post 10 vertically fixed at both ends. Each shaping block 6 is slidably connected to the sliding post 10 and is fitted with a first return spring 11 in the same position. The pneumatic module 4 is used to pneumatically press down the top of the workpiece. The pressure plate platform 3 also has a top rod 12 vertically sliding at the bottom of the corresponding external workpiece. The outer wall of the top rod 12 is fitted with a second return spring 13 for axial return.

[0027] Furthermore, the pneumatic module 4 includes a servo cylinder 14, a sliding guide rod 15, and a lower pressure plate 16. The servo cylinder 14 is fixed to the top of the frame 1, and its output end is axially limited by the sliding guide rod 15 and fixedly connected to the lower pressure plate 16 at the output end. The lower pressure plate 16 has four symmetrically fixed first limiting posts 17 at its bottom corners, and a second limiting post 18 is fixed to the outside of one pair of the first limiting posts 17. The pressure plate platform 3 has a third limiting post 19 and a fourth limiting post 20 vertically fixed at the corresponding first limiting posts 17 and second limiting posts 18, respectively. When the bottom surface of the lower pressure plate 16 contacts the top of the external workpiece, the second limiting post 18 and the fourth limiting post 20 are connected. When the external workpiece is pressed down to the maximum depth, the fourth limiting post 20 is embedded in the second limiting post 18, and the first limiting post 17 and the third limiting post 19 are simultaneously in contact.

[0028] With the above structure, during the actual shaping process, the pneumatic module 4 can drive the lower pressure plate 16 to press down the workpiece to provide the required external driving force. When the bottom surface of the lower pressure plate 16 contacts the top of the external workpiece, the second limiting post 18 is connected to the fourth limiting post 20 (not embedded). When the external workpiece is pressed down to the maximum depth, the fourth limiting post 20 is embedded in the second limiting post 18, and the first limiting post 17 and the third limiting post 19 are in contact simultaneously. The overall stroke can be controlled within 40mm (i.e., the distance between the first limiting post 17 and the third limiting post 19).

[0029] After the workpiece is pressed down, the two shaping blocks 6 can be pushed synchronously on the slide table 8 by the slope 9 to slide relative to each other, with the stroke controlled within 8.5mm. The back of the shaping block 6 is connected to the nylon block 24 by the fixing plate 23 to contact the surrounding plate 5. After the workpiece is removed, the shaping block 6 can be reset by the sliding column 10 on the positioning column 7 and the first return spring 11. Similarly, the top rod 12 placed in the center of the pressure plate platform 3 can also support the bottom of the workpiece and reset by the second return spring 13 for the workpiece to be removed. The shaping process is the squeezing effect of the two shaping blocks 6 on one side of the workpiece. The wedge-shaped squeezing method is stable and reliable and does not easily cause wear on the surface of the workpiece.

[0030] Similarly, an adjusting column 21 is vertically fixed on the pressure plate platform 3. Multiple adjusting blocks 22 are sleeved on the adjusting column 21. Each adjusting block 22 can be movably fixed on the top of the third limiting column 19 to match different types of external workpieces.

[0031] To further improve the overall stability of the forming mechanism during the extrusion and shaping of the external workpiece by the forming blocks 6, this design includes fixing plates 23 on opposite sides of the two forming blocks 6. Multiple nylon blocks 24 are evenly distributed on the outer side of the fixing plates 23 to contact the surrounding plate 5. Fixing blocks 25 are respectively fixed to the outer sides of the two sliding tables 8 to connect and fix them to the surrounding plate 5.

[0032] Furthermore, one side of the frame 1 has an opening, and a laser safety device is installed at the opening. When an operator enters the frame 1, the entire machine can be automatically shut down to prevent accidental injury. An electrical cabinet 26 is integrated into the opening side of the frame 1, and a workbench 27 is fixed below the electrical cabinet 26. The electrical cabinet 26 is electrically connected to the electrical module. Operators can uniformly control the pneumatic servo operating amplitude and frequency through the electrical cabinet 26. Similarly, a forklift bay 28 is provided at the bottom of the frame 1 for external forklift transportation operations.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
