Description

Technical Field

[0001] This utility model relates to the field of square mesh manufacturing technology, specifically a metal square mesh rolling tool for casting molten aluminum. Background Technology

[0002] When manufacturing motorcycle wheels, the wheels are mainly formed by casting an appropriate amount of molten aluminum. At the same time, considering the need to filter impurities in the molten aluminum and reduce the impact force when pouring the molten aluminum during the motorcycle wheel hub casting process, commonly used auxiliary tools include casting square mesh.

[0003] Currently, more than half of the products in the workshop require the use of square mesh in production (to reduce splashing of molten aluminum during the pouring process). However, each employee has different skills in making square mesh, and many of them are not sealed and have different shapes, which fails to prevent splashing of molten aluminum. The products still have many pits and slag holes. In addition, making square mesh is easy to prick the hands, so employees are not very enthusiastic about making and using it. Therefore, in order to solve the above problems, a metal square mesh rolling tool for casting molten aluminum is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a metal square mesh rolling tool for casting molten aluminum, in order to solve the problems mentioned in the background art, such as the ease with which it is easy to prick hands and the low enthusiasm of employees for making and using square mesh.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] A metal square mesh rolling tool for casting molten aluminum includes a right disc 1. A connecting rod 2 is fixedly connected to the left side of the right disc 1. A left disc 3 is fixedly connected to the left side of the connecting rod 2. A limiting chuck 5 is fixedly connected to the right side of the right disc 1. An inner tube 6 is rotatably connected to the middle of the right side of the limiting chuck 5. A first slit 7 is opened at the top of the inner tube 6. An outer tube 8 is sleeved on the outside of the inner tube 6 and engages with the limiting chuck 5. A second slit 9 is opened at the top of the outer tube 8. A fixed support 12 is sleeved on the outside of the outer tube 8 and is fixedly connected to the limiting chuck 5. A support ring 10 is fixedly connected to the right side of the inside of the fixed support 12. A fixing pin 11 is inserted into the right side of the outer tube 8.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, the connecting rods 2 are arranged in a circular array along the center point of the right disc 1. The right disc 1 and the left disc 3 are both disc-shaped. The three connecting rods 2 mainly serve to connect the right disc 1 and the left disc 3. The operating lever 4 passes through the center of the right disc 1. The operating lever 4 passes through the interior of the limiting chuck 5 and is fixedly connected to the inner tube 6. The operating lever 4 passes through the interior of the left disc 3. The operating lever 4 has a "Z" shaped structure. When operating the entire tool to make a square net, the "Z" shaped design of the operating lever 4 makes the manual crank operation more effortless and convenient. The bottom of the left disc 3 and the right disc 1 are respectively fixedly connected to the uprights 16. The bottom end of the uprights 16 is fixedly connected to the fixed boss 17. The bottom end of the fixed boss 17 is fixedly connected to the fixed base 23.

[0025] like Figure 1 , Figure 2 and Figure 5 As shown, pressure blocks 19 are respectively engaged at the four corners of the fixed boss 17. A movable outer ring 18 is fixedly connected to the outside of the pressure block 19. A guide rod 20 that passes through the fixed base 23 is fixedly connected to the bottom four corners of the movable outer ring 18. A suction cup 21 is fixedly installed at the bottom of the guide rod 20. A spring 22 is sleeved on the upper outer side of the guide rod 20. The spring 22 is fixedly connected to the movable outer ring 18 and the fixed base 23 respectively. After the fixed base 23 is placed flat on the horizontal platform, the suction cup 21 can be pressed down and adjusted so that it can perform adsorption.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the gap size of the first slit 7 is smaller than that of the second slit 9, the length of the inner tube 6 is smaller than that of the outer tube 8, the fixed support 12 has a semi-circular structure, and the right side of the fixed support 12 has a slot for mounting the fixing pin 11. The inner side of the outer tube 8 is fixedly connected to the inner sleeve 15. After the inner tube 6 and the outer tube 8 are fitted together, the inner tube 6, the outer tube 8 and the fixed support 12 will form a curling space, so that the entire tool can achieve the curling and shaping of the net by shaking. The bottom of the support ring 10 has a fastening sleeve 13 that passes through the fixed support 12. The bottom of the fastening sleeve 13 is threaded with a fastening bolt 14. The fastening bolt 14 and the inner sleeve 15 are set together. When the outer tube 8 is fitted, the support ring 10 mainly plays an auxiliary supporting role. At the same time, with the use of the fastening bolt 14 and the inner sleeve 15, the outer tube 8 can be fastened and limited after it is installed.

[0027] Workflow: During the casting and processing of motorcycle wheels, a casting square mesh needs to be made for filtering molten aluminum. First, place the tool flat on the platform using the fixed base 23. After ensuring the platform is clean, press down the movable outer ring 18 repeatedly to compress the spring 22, creating a negative pressure suction between the suction cup 21 and the platform. The multiple suction cups 21 will then firmly adhere to the platform, allowing the two fixed bases 23 to support the entire tool for stable placement. Next, align the outer tube 8 with the pre-drilled groove inside the limiting chuck 5 and place it on the support ring 10. Push the outer tube 8 from right to left towards the inside of the fixed support 12. Once it has moved to the left, the outer tube 8 will engage with the limiting chuck 5 and fit snugly onto the outside of the inner tube 6. Then, align the slot and insert the fixing pin 11 into the inside of the outer tube 8 for a final fixation. Finally, tighten the fastening bolt 1 upwards. 4. Insert the top of the fastening bolt 14 through the support ring 10 and into the inner sleeve 15 for secondary confinement. At this point, the combination of the inner and outer sleeves is complete. Then, insert the square mesh to be rolled into the first slit 7. Under the connection and confinement of the right disc 1, connecting rod 2 and left disc 3, shake the operating lever 4 so that the square mesh can be relatively rolled and shaped as the inner tube 6 rotates. After shaking for 2 revolutions, the square mesh will be rolled and shaped in the curling space formed by the inner tube 6, the outer tube 8 and the fixed support 12. Finally, pull out the fixed pin 11 and turn the adjusting fastening bolt 14 downward to separate the fastening bolt 14 from the inner sleeve 15. Then, pull out the outer tube 8 from the fixed support 12 and take out the rolled square mesh. The single square mesh rolling operation can be completed. In the future, just follow the above operation steps to facilitate the batch production of square mesh.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
