Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy castings, in particular to a trimming device for processing aluminum die castings. Background Art

[0002] Aluminum alloy die castings refer to equipment and devices made of pure aluminum or aluminum alloys by casting. They are widely used in various fields such as automobiles and aviation due to their advantages such as beautiful appearance, high strength, light weight and corrosion resistance. When processing aluminum alloy die castings, trimming is one of the essential steps.

[0003] After searching, the China Patent Network disclosed a trimming device for aluminum die-casting processing, with the publication number CN217474814U. Although the trimming device for aluminum die-casting processing is coordinated with a cutter, a nozzle, a water tank and a connecting pipe, when trimming the die-casting, the debris is processed in time while avoiding excessive heat accumulation during trimming, which affects the die-casting process, effectively ensuring the stability of the trimming. At the same time, through the coordination of the filter plate and the connecting pipe, the recycling of water resources is realized, effectively reducing the waste of resources. Since the cutter is prone to wear during use, and the cutter in the patent is not easy to disassemble, it is not easy to maintain the cutter, which affects the trimming efficiency of the die-casting.

[0004] Therefore, a trimming device for processing aluminum die castings is proposed. Utility Model Content

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0040] Example 1:

[0041] See also Figure 1-5 , the utility model provides a technical solution: in order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a trimming device for aluminum die casting processing, comprising: a workbench 1; an L-shaped seat 2 is fixed on the top of the workbench 1; a first hydraulic cylinder 4 and a second hydraulic cylinder 7 are installed at the bottom of the L-shaped seat 2, and a first hydraulic rod 5 and a second hydraulic rod 8 are installed at the bottom of the first hydraulic cylinder 4 and the second hydraulic cylinder 7 respectively; a cutter 6 is installed at the bottom of the first hydraulic rod 5; a fixing plate 9 is fixed to the bottom of the second hydraulic rod 8; a water injection cavity is opened inside the cutter 6, and an overflow hole 30 is opened on the outer wall of the cutter 6; a connecting pipe 31 connected to the water injection cavity is installed on the outer wall of the cutter 6, and one end of the connecting pipe 31 is connected to the external cold water pipe; a first mounting groove 10 is opened on the top of the workbench 1, and a second mounting groove 11 is opened on the right outer wall of the workbench 1, and a box 12 is installed in the first mounting groove 10 and the second mounting groove 11; a U A water storage tank 14 is provided on the top of the box body 12; a limit frame 15 is fixed on the inner wall of the water storage tank 14, a filter plate 16 is placed in the water storage tank 14, and the bottom of the filter plate 16 abuts against the top of the limit frame 15; a connecting sleeve 18 is fixed on the top of the cutter 6, and an internal thread 19 is provided on the inner wall of the connecting sleeve 18, and an external thread 17 is provided on the outer wall of the first hydraulic rod 5; the connecting sleeve 18 is threadedly connected to the outer wall of the first hydraulic rod 5 through the internal thread 19 and the external thread 17, and the first hydraulic rod 5 is provided with an external thread 17. An L-shaped bar 20 is fixed to the outer wall of a hydraulic rod 5, a first clamping hole 21 is opened on the outer wall of the L-shaped bar 20, a second clamping hole 22 is opened on the outer wall of the connecting sleeve 18, and a fixing rod 23 is clamped in the first clamping hole 21 and the second clamping hole 22; an auxiliary plate 24 is fixed to one end of the fixing rod 23, a receiving plate 25 is fixed to the outer wall of the fixing rod 23, and a spring 26 is provided on the outer wall of the fixing rod 23, one end of the spring 26 is fixed to the L-shaped bar 20, and the other end of the spring 26 is fixed to the receiving plate 25.

[0042] Specifically, since the connecting sleeve 18 is threadedly connected to the outer wall of the first hydraulic rod 5 through the internal thread 19 and the external thread 17, the cutter 6 can be disassembled by simply rotating the cutter 6 and the connecting sleeve 18 in the opposite direction along the threaded connection direction of the external thread 17 and the internal thread 19. Compared with the existing ones, the present invention facilitates the disassembly and maintenance of the cutter 6, thereby improving the trimming efficiency of the die casting.

[0043] And under the action of the spring 26, the fixing rod 23 is driven to move. When one end of the fixing rod 23 is engaged with the inside of the second engaging hole 22, the connecting sleeve 18 and the cutter 6 can be fixed, thereby preventing the cutter 6 from loosening and deflecting during operation, thereby improving the efficiency and accuracy of trimming the die casting.

[0044] It should be noted that before disassembling the cutter 6, it is necessary to pull the fixing rod 23 through the auxiliary plate 24. At this time, the spring 26 will perform a stretching movement. After one end of the fixing rod 23 is disengaged from the second clamping hole 22, the cutter 6 can be disassembled. The purpose is to prevent the fixing rod 23 from preventing the connecting sleeve 18 and the cutter 6 from rotating.

[0045] Example 2:

[0046] See also Figure 1 、 6 The utility model provides a technical solution: a trimming device for processing aluminum die-castings, a threaded part 27 is fixed to the outer wall of the right side of the workbench 1, and a rotating ring 28 is movably connected to the outer wall of the threaded part 27, and a fixing bar 29 is fixed to the outer wall of the rotating ring 28, and one end of the fixing bar 29 abuts against the outer wall of the right side of the box body 12, and the outer wall of the threaded part 27 is threadedly connected to a limiting ring 3, and one end of the limiting ring 3 abuts against the rotating ring 28.

[0047] Specifically, by rotating the limit ring 3 and making the limit ring 3 non-contact with the rotating ring 28, the rotating ring 28 can be moved and the fixing bar 29 can be non-contacted with the right outer wall of the box body 12. At this time, the box body 12 can be disassembled. On the one hand, it is convenient to recycle the water in the water storage tank 14 of the box body 12. On the other hand, it is convenient to clean the debris of the die-cast part on the top of the filter plate 16, which is relatively simple to use.

[0048] Working principle:

[0049] First, place the die-casting on the top of the workbench 1, then start the second hydraulic cylinder 7, which will drive the fixing plate 9 to move downward through the second hydraulic rod 8. After the fixing plate 9 abuts against the die-casting, the die-casting can be fixed;

[0050] Then, the first hydraulic cylinder 4 is activated, which activates the cutter 6 to descend through the first hydraulic rod 5. After the cutter 6 contacts the die-casting, the die-casting can be trimmed. At the same time as the first hydraulic cylinder 4 is activated, cold water from the external cold water pipe enters the water injection cavity of the cutter 6 through the connecting pipe 31 and drips onto the die-casting through the overflow hole 30, thereby achieving the purpose of cooling the die-casting and the cutter 6.

[0051] The cold water used to cool the die castings and slices will then enter the water storage tank 14, and the trimmings of the die castings will also enter the top of the filter plate 16;

[0052] Secondly, since the connecting sleeve 18 is threadedly connected to the outer wall of the first hydraulic rod 5 through the internal thread 19 and the external thread 17, the cutter 6 can be disassembled by simply rotating the cutter 6 and the connecting sleeve 18 in the opposite direction along the threaded connection direction of the external thread 17 and the internal thread 19. Compared with the existing ones, the present invention facilitates the disassembly and maintenance of the cutter 6, thereby improving the efficiency of trimming the die casting.

[0053] And under the action of the spring 26, the fixing rod 23 is driven to move. When one end of the fixing rod 23 is engaged with the inside of the second engaging hole 22, the connecting sleeve 18 and the cutter 6 can be fixed, thereby preventing the cutter 6 from loosening and deflecting during operation, thereby improving the efficiency and accuracy of trimming the die casting.

[0054] It should be noted that before removing the cutter 6, it is necessary to pull the fixing rod 23 through the auxiliary plate 24. At this time, the spring 26 will stretch. After one end of the fixing rod 23 is disengaged from the second clamping hole 22, the cutter 6 can be removed. The purpose is to prevent the fixing rod 23 from preventing the connecting sleeve 18 and the cutter 6 from rotating.

[0055] Finally, by rotating the limit ring 3 and making the limit ring 3 non-contact with the rotating ring 28, the rotating ring 28 can be moved and the fixing bar 29 can be non-contacted with the right outer wall of the box body 12. At this time, the box body 12 can be disassembled. On the one hand, it is convenient to recycle the water in the water storage tank 14 of the box body 12. On the other hand, it is convenient to clean the debris of the die-casting on the top of the filter plate 16, which is relatively simple to use.
