Description

Technical Field

[0001] This invention belongs to the field of casting technology, and specifically relates to an extrusion device for aluminum bronze rods. Background Technology

[0002] Bronze rods refer to rods formed from bronze billets into rods of certain specifications. According to the production method, they can be divided into drawn rods and extruded rods. According to the shape, they can be divided into round, square, hexagonal and irregular shapes. According to the material, they can be divided into rods of tin bronze, aluminum bronze, beryllium bronze, silicon bronze, cadmium bronze, etc.

[0003] Existing aluminum bronze rod extrusion devices generally lack auxiliary stirring rods during the softening process. This results in slow softening, as the temperature in the casting furnace only begins to rise from the point of contact with the high-temperature heat-conducting furnace wall. Furthermore, existing auxiliary stirring rods have a simple structure and limited function, only capable of stirring and unable to scrape and clean the copper slag adhering to the furnace wall after casting. The extrusion tubes in existing aluminum bronze rod extrusion devices are mostly fixed to the device with mounting nuts, requiring disassembly tools and making disassembly cumbersome. This also hinders the repair and replacement of damaged extrusion tubes. Therefore, we propose an aluminum bronze rod extrusion device. Summary of the Invention

[0015] 1. The design incorporates a furnace structure, a shrinkage fixing mechanism, a stirring rod, a stirring heating rod, a scraper, a positioning block, a limiting connecting plate, a shrinkage cavity, a shrinkage limiting groove, a first magnetic plate, a second magnetic plate, a slide rail groove, a fixing pin groove, a shrinkage rod, a slide rail block, a receiving cavity column, a fixing pin, and a return spring. During use, the aluminum bronze billet is placed into the casting tank located inside the furnace body. The device is then powered on, and the heat radiated from the heating pipes inside the casting tank and the heat-conducting furnace wall preheats and softens the aluminum bronze billet. During the softening process, the first motor drives the stirring rod and stirring heating rod to rotate. The heat-conducting stirring rod and stirring heating rod stir the aluminum bronze billet, allowing it to soften evenly. During scraping, the positioning block is pulled, causing the shrinking rod to slide along the inner side of the receiving cavity column to the top of the inner side of the receiving cavity column. This causes the fixing slot at the bottom of the positioning block to separate from the outer side of the top of the fixing slot. Then, the scraper is pulled, causing the limiting connecting plate fixedly connected to one end of the scraper to move outward along the shrinking cavity synchronously. This causes the shrinkage limiting block, fixedly connected to the bottom of the limiting connecting plate, to move outward along the inner side of the shrinkage limiting groove. Once the scraper has slid properly, the positioning block is pushed, causing the slide rail groove fixedly connected to the bottom of the positioning block to slide back to its original position along the outer side of the slide rail block. This ensures the adjusted position of the scraper remains unchanged. Then, the tension on the positioning block is released, and under the action of the return spring, the positioning block is pressed down, causing the fixing pin groove fixedly connected to the bottom of the positioning block to engage with the outer side of the top of the fixing pin, thus fixing the adjusted position of the scraper and preventing the scraper from... The position changes, and then the first motor drives the stirring rod and stirring heating rod to rotate, which in turn drives the scraper blade, which can be adjusted and attached to the inner wall of the casting tank, to rotate. The rotating scraper blade scrapes and cleans the aluminum bronze fragments adhering to the inner wall of the casting tank, which helps to improve the casting efficiency of copper material and makes it easy to put the scraper blade in place and fix it. Thus, the stirring and scraping cleaning are integrated, which can achieve the goal of stirring the copper material to accelerate the casting efficiency and facilitate the scraping and cleaning of the inner side of the casting tank after casting is completed.

[0016] 2. Through the designed installation and fixing structure, extruded tube installation structure, and extruded tube structure, during installation, the corresponding model of shrink-fit tube is inserted into the first clamp arc-shaped groove fixedly connected to one end of the bottom inner side of the main body. Then, the protruding clamp installation tube is pushed, causing the sliding block fixedly connected to the middle of the outer side of the clamp installation tube to move along the sliding groove provided on the inner side of the shrink-fit tube towards the clamp tube. This causes one end of the outer side of the clamp installation tube to slide and engage with the inner side of the clamp tube. Then, the fixing block is pressed, causing the limiting block fixedly connected to the middle of one end of the fixing block to move down along the inner side of the limiting groove, so that the bottom end of the fixing block engages with the positioning groove, fixing the position of the clamp installation tube. Finally, the sealing installation cover is attached to the main body. The sealing block and the second clamp arc groove, which are fixedly connected to the bottom of the sealing installation cover, are respectively engaged in the sealing groove and the first clamp arc groove. The second clamp arc groove and the first clamp arc groove cooperate to clamp the outside of the shrink clamp tube, fixing the position of the shrink clamp tube after installation. Then, the installation clamp plate on the outside of the sealing installation cover is engaged in the installation clamp post on the top of the outside of the main body. The sliding clamp arc plate allows the clamp arc plate to slide steadily along the inner side of the limiting groove and the outer side of the limiting fixing block and engage with the inner side of the clamp arc groove, fixing the position of the sealing installation cover. This facilitates the installation and disassembly of the extrusion tube in the casting device and the repair and replacement of damaged extrusion tubes. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-10 The present invention provides a technical solution: an extrusion device for aluminum bronze rods, comprising a main body 1, a sealing groove 7 fixedly connected to the top end of the main body 1, a sealing mounting cover 2 snapped onto the top end of the sealing groove 7, a melting furnace structure 3 provided at one end of the top end of the sealing mounting cover 2, an air injection hole 8 fixedly connected to the top end of the middle part of one end of the main body 1, an extrusion tube mounting structure 5 provided at one end of the bottom inner side of the main body 1, an extrusion tube structure 6 snapped onto the inner side of the extrusion tube mounting structure 5, and an installation fixing structure 4 provided on the outer side of the sealing mounting cover 2;

[0030] The casting furnace structure 3 includes a casting furnace body 31. A secondary gear 32 is provided in the middle of one side of the casting furnace body 31. A first motor 33 is provided in the middle of one side of the secondary gear 32. A main gear 34 is meshed with the bottom end of the secondary gear 32. A second motor 35 is provided in the middle of one side of the main gear 34. A casting tank 36 is fixedly connected in the middle of the other side of the secondary gear 32. The casting tank 36 is located in the middle of the inner side of the casting furnace body 31. A stirring rod 37 is fixedly connected to the output end of the first motor 33. Multiple sets of stirring heating rods 38 are fixedly connected to both ends of the stirring rod 37. A scraper 39 is snapped into one end of the stirring heating rod 38. A positioning block 310 is snapped into the middle of one end of the top of the stirring heating rod 38. A shrinkage fixing mechanism 9 is fixedly connected to one end of the inner side of the stirring heating rod 38.

[0031] In this embodiment, through the designed casting furnace structure 3, when in use, the aluminum bronze billet is placed into the casting tank 36 provided inside the casting furnace body 31. The device power is turned on, and the heat emitted by the heating pipes and heat-conducting furnace wall provided inside the casting tank 36 preheats and softens the aluminum bronze billet in the casting tank 36. During the softening process, the first motor 33 drives the stirring rod 37 and the stirring heating rod 38 to rotate. The heat-conducting stirring rod 37 and the stirring heating rod 38 stir the aluminum bronze billet, so that the aluminum bronze billet can be heated and softened evenly, which is beneficial to improving the casting efficiency of copper material.

[0032] Specifically, the shrinking and fixing mechanism 9 includes a shrinking cavity 91. The outer side of the shrinking cavity 91 is fixedly connected to one end of the inner side of the stirring heating rod 38. A shrinking limiting groove 92 is fixedly connected to one side of the bottom end of the inner side of the shrinking cavity 91. A limiting connecting plate 94 is slidably connected to one end of the inner side of the shrinking cavity 91. A second magnetic piece 95 is fixedly connected to one end of the limiting connecting plate 94. A first magnetic piece 93 is fixedly connected to the other end of the inner side of the shrinking cavity 91. A slide rail groove 96 is fixedly connected to the middle of the bottom end of the positioning block 310. Fixed locking post grooves 97 are fixedly connected to both ends of the bottom end of the positioning block 310. A receiving cavity column 910 is fixedly connected to the middle of the top end of the limiting connecting plate 94. A shrinking rod 98 is slidably connected to the inner side of the receiving cavity column 910. A slide rail block 99 is fixedly connected to the middle of the top end of the shrinking rod 98. A fixed locking post 911 is provided on one side of the receiving cavity column 910. A return spring 912 is provided on the outer side of the shrinking rod 98.

[0033] In this embodiment, through the designed shrinkage fixing mechanism 9, during scraping, pulling the positioning block 310 causes the shrinkage rod 98 to slide along the inner side of the receiving cavity column 910 to the top of the inner side of the receiving cavity column 910, thereby causing the fixing pin groove 97 fixedly connected to the bottom end of the positioning block 310 to separate from the outer side of the top end of the fixing pin 911. Then, pulling the scraper 39 causes the limiting connecting plate 94 fixedly connected to one end of the scraper 39 to move outward along the shrinkage cavity 91, and simultaneously causes the shrinkage limiting block fixedly connected to the bottom end of the limiting connecting plate 94 to move outward along the inner side of the shrinkage limiting groove 92. After the scraper 39 has slid properly, pushing the positioning block 310 causes the slide rail groove 96 fixedly connected to the bottom end of the positioning block 310 to slide back to its original position along the outer side of the slide rail block 99, while ensuring adjustment. The position of the adjusted scraper 39 remains unchanged. Then, the tension on the positioning block 310 is released. Under the action of the return spring 912, the positioning block 310 is pressed down, causing the fixing slot 97 fixedly connected to the bottom of the positioning block 310 to lock onto the outer side of the top of the fixing slot 911, thus fixing the adjusted position of the scraper 39 and preventing the scraper 39 from moving. Then, the first motor 33 drives the stirring rod 37 and the stirring heating rod 38 to rotate, thereby driving the scraper 39, which can be adjusted to fit against the inner wall of the casting tank 36, to rotate. The rotating scraper 39 scrapes and cleans the aluminum bronze fragments adhering to the inner wall of the casting tank 36. It is convenient to retract and fold the scraper and extend and open it, so as to facilitate scraping and cleaning the inner side of the casting tank after casting is completed.

[0034] Specifically, the mounting and fixing structure 4 includes a mounting clamp plate 41. A mounting clamp hole 42 is fixedly connected to the bottom of the middle part of one side of the mounting clamp plate 41. A mounting clamp post 43 is engaged inside the mounting clamp hole 42. A clamp arc groove 44 is fixedly connected to one side of the middle part of one end of the mounting clamp post 43. A clamp arc plate 45 is engaged inside the clamp arc groove 44. A limit block is fixedly connected to one side of the clamp arc plate 45. A limit groove 47 is slidably connected to the outer side of the limit block. A limit fixing block 46 is slidably connected to the inner side of the clamp arc plate 45. The limit fixing block 46 is located at the top of the mounting clamp hole 42.

[0035] In this embodiment, the installation and fixing structure 4 is designed to attach the mounting clamp plate 41 on the outer side of the sealing cover 2 to the mounting clamp post 43 on the top outer side of the main body 1. The sliding clamp arc plate 45 allows the clamp arc plate 45 to slide steadily along the inner side of the limiting groove 47 and the outer side of the limiting fixing block 46 and be fixed to the inner side of the clamp arc groove 44, thus fixing the position of the sealing cover 2. This makes it easier to install and remove the sealing cover 2, and the installation and removal are more convenient and labor-saving.

[0036] Specifically, the extruded tube installation structure 5 includes a clamp tube 51, one end of which is slidably connected to a fixing block 52, the middle of one end of the fixing block 52 is fixedly connected to a limiting block 53, the outer side of the limiting block 53 is slidably connected to a limiting groove 54, the outer side of the bottom end of the fixing block 52 is connected to a positioning groove 55, one end of the bottom inner side of the main body 1 is fixedly connected to a first clamp arc-shaped groove 56, the top of the first clamp arc-shaped groove 56 is connected to a second clamp arc-shaped groove 57, the top of the second clamp arc-shaped groove 57 is fixedly connected to the bottom end of the sealing installation cover 2, and the extruded tube structure 6 includes a clamp installation tube 61, the middle of the outer side of the clamp installation tube 61 is fixedly connected to a sliding block 62, the outer side of the sliding block 62 is slidably connected to a sliding groove 63, and the outer side of the sliding groove 63 is fixedly connected to a shrink clamp tube 64.

[0037] In this embodiment, through the designed extruded tube installation structure 5 and extruded tube structure 6, during installation, the corresponding model of shrink clamp tube 64 is clamped into the first clamp arc-shaped groove 56 fixedly connected to one end of the bottom inner side of the main body 1. Then, the protruding clamp installation tube 61 is pushed, so that the sliding block 62 fixedly connected to the middle of the outer side of the clamp installation tube 61 moves along the sliding groove 63 provided on the inner side of the shrink clamp tube 64 towards the clamp tube 51, thereby driving one end of the outer side of the clamp installation tube 61 to slide and clamp onto the inner side of the clamp tube 51. Then, the fixing block 52 is pressed, so that the limiting block 53 fixedly connected to the middle of one end of the fixing block 52 moves along the limiting block. The inner side of the groove 54 moves downward so that the bottom end of the fixing block 52 is engaged in the positioning groove 55, fixing the position of the clamp installation tube 61. Then, the sealing installation cover 2 is engaged on the main body 1, so that the sealing block and the second clamp arc groove 57, which are fixedly connected to the bottom end of the sealing installation cover 2, are engaged in the sealing groove and the first clamp arc groove 56, respectively. The second clamp arc groove 57 and the first clamp arc groove 56 cooperate with each other to clamp the outside of the shrink clamp tube 64, fixing the position of the shrink clamp tube 64 after installation. This facilitates the installation and disassembly of the extrusion tube in the casting device and the repair and replacement of damaged extrusion tubes.

[0038] Specifically, one end of the clamp mounting tube 61 is fixedly connected to the positioning groove 55, the inner side of the sliding block 62 is provided with a sliding hole, the middle of the inner side of the sliding groove 63 is provided with a limiting sliding rod, the inner side of the sealing groove 7 is fitted with a sealing block, the top of the sealing block is fixedly connected to the bottom of the sealing mounting cover 2, the size of the inner side of the sealing groove 7 matches the size of the outer side of the sealing block, there are two sets of fixing blocks 52, four sets of limiting blocks 53, four sets of limiting grooves 54, and two sets of positioning grooves 55.

[0039] In this embodiment, the designed sliding groove 63, sliding block 62, sliding hole, and limiting slide rod allow for the following operation: When the protruding clamp mounting tube 61 is pushed, the sliding block 62, which is fixedly connected to the middle of the outer side of the clamp mounting tube 61, slides along the sliding groove 63 provided on the inner side of the shrink clamp tube 64. At the same time, the sliding hole, which is fixedly connected to the inner side of the sliding block 62, moves along the outer side of the limiting slide rod provided on the middle of the inner side of the sliding groove 63 towards the clamp tube 51. This helps prevent the clamp mounting tube 61 from shaking during the sliding movement and improves the stability of the clamp mounting tube 61 during sliding.

[0040] Working principle: During installation, the corresponding model of shrink clamp tube 64 is inserted into the first clamp arc-shaped groove 56 fixedly connected to one end of the bottom inner side of the main body 1. Then, the protruding clamp mounting tube 61 is pushed, causing the sliding block 62 fixedly connected to the middle of the outer side of the clamp mounting tube 61 to move along the sliding groove 63 provided on the inner side of the shrink clamp tube 64 towards the clamp tube 51, thereby causing one end of the outer side of the clamp mounting tube 61 to slide and engage with the inner side of the clamp tube 51. Then, the fixing block 52 is pressed, causing the limiting block 53 fixedly connected to the middle of one end of the fixing block 52 to move down along the inner side of the limiting groove 54, so that the bottom end of the fixing block 52 engages with the positioning groove 55, fixing the position of the clamp mounting tube 61. Finally, the sealing mounting cover 2 is inserted into the main body 1, so that the seal is engaged. The sealing block and the second clamp arc groove 57, which are fixedly connected to the bottom of the mounting cover 2, are respectively snapped into the sealing groove and the first clamp arc groove 56. The second clamp arc groove 57 and the first clamp arc groove 56 cooperate to clamp the outside of the shrink clamp tube 64, fixing the position of the shrink clamp tube 64 after installation. Then, the mounting clamp plate 41 provided on the outside of the sealing mounting cover 2 is snapped into the mounting clamp post 43 provided at the top of the outside of the main body 1. The clamp arc plate 45 is slid so that the clamp arc plate 45 slides steadily along the inner side of the limiting groove 47 and the outer side of the limiting fixing block 46 and is snapped into the inner side of the clamp arc groove 44, fixing the position of the sealing mounting cover 2. When in use, the aluminum bronze billet is placed into the melting and casting tank 3 provided on the inner side of the melting and casting furnace main body 31. 6. The device is powered on. Heat radiated from the heating pipes inside the casting tank 36 and the heat-conducting furnace wall preheats and softens the aluminum bronze billet in the casting tank 36. During the softening process, the first motor 33 drives the stirring rod 37 and the stirring heating rod 38 to rotate. The heat-conducting stirring rod 37 and the stirring heating rod 38 stir the aluminum bronze billet, ensuring it is evenly heated and softened. After the aluminum bronze billet has softened to a certain extent, the second motor 35 drives the main gear 34 to rotate, which in turn drives the secondary gear 32, which meshes with the main gear 34, to rotate. This causes the casting tank 36 to rotate 180 degrees. The softened aluminum bronze billet inside the casting tank 36 falls vertically into one end of the main body 1 under gravity, and is then driven by the second motor 35... The main gear 34 rotates, thereby driving the secondary gear 32, which meshes with the main gear 34, to rotate. This causes the casting tank 36 to rotate 180 degrees in the opposite direction, moving it back to its original position. Then, an air pump installed at one end of the air injection hole 8 continuously injects gas into the inside of the main body 1. Under the pressure of the air, the softened aluminum bronze billet is squeezed into the clamp mounting tube 61 of the extrusion tube structure 6. The clamp mounting tube 61 performs preliminary shaping of the copper rod. After preliminary shaping, the shaped aluminum bronze billet moves under the action of air pressure into the copper rod mold installed at one end of the clamp mounting tube 61 for the next step. After the device is used up, the positioning block 310 is pulled, causing the retraction rod 98 to slide along the inside of the receiving cavity column 910 to the top of the inside of the receiving cavity column 910.This causes the fixing slot 97, which is fixedly connected to the bottom of the positioning block 310, to separate from the outer side of the top of the fixing slot 911. Then, the scraper 39 is pulled, causing the limiting connecting plate 94, which is fixedly connected to one end of the scraper 39, to move outward along the shrinkage cavity 91. Simultaneously, the shrinkage limiting block, which is fixedly connected to the bottom of the limiting connecting plate 94, moves outward along the inner side of the shrinkage limiting groove 92. After the scraper 39 has slid properly, the positioning block 310 is pushed, causing the slide rail groove 96, which is fixedly connected to the bottom of the positioning block 310, to slide back to its original position along the outer side of the slide rail block 99, while ensuring that the adjusted position of the scraper 39 remains unchanged. Then, the pulling force on the positioning block 310 is released. Under the action of the return spring 912, the positioning block 310 is pressed down, causing the fixing slot 97, which is fixedly connected to the bottom of the positioning block 310, to engage with the outer side of the top of the fixing slot 911. This fixes the adjusted position of the scraper 39, preventing it from moving. Then, the first motor 33 drives the stirring rod 37 and the stirring heating rod 38 to rotate, thereby rotating the scraper 39, which can now be attached to the inner wall of the casting tank 36. The rotating scraper 39 scrapes and cleans the aluminum bronze fragments adhering to the inner wall of the casting tank 36, preventing the fragments from adhering to the inner wall of the device for a long time and affecting the efficiency of the next operation.

[0041] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
