Description

Technical Field

[0001] The present invention relates to the technical field of hot-dip galvanized alloy ingots, and particularly to an automated continuous production process for large hot-dip galvanized alloy ingots. Background Art

[0002] The automated production process for large zinc alloy ingots requires the use of an automated continuous production line. The existing automated continuous production line for large zinc alloy ingots consists of a disk ingot casting machine, a conveyor line, a gantry crane, a demolding device, and a robotic slag skimming device. The ingots are cast using the disk ingot casting machine and then transported to the robotic slag skimming device for slag skimming. Subsequently, they are transported to the gantry crane, where the mold is lifted onto the conveyor line and transported to the demolding device. Then, it is moved to the demolding device by the gantry crane at the demolding device for demolding. The empty mold after demolding is then lifted by the gantry crane onto the empty mold conveyor line and transported back to the disk ingot casting machine, and then lifted onto the disk ingot casting machine.

[0003] In this way, the continuous automated production of large zinc alloy ingots is achieved, greatly improving production efficiency and saving labor. However, when it is in use, there are still certain problems with the structure of the gantry crane. The existing gantry crane for the continuous production of large zinc alloy ingots only has one lifting tool when in use. It is necessary to lift the empty mold from the automatic demolding machine onto the return conveyor belt and then come back to load the full mold onto the automatic demolding machine, and it is impossible to perform the loading and unloading of the molds on the automatic demolding machine simultaneously. Moreover, the gantry crane lifting tool on the existing continuous automated production line for large zinc alloy ingots needs to be equipped with two finger clamps separately to complete the lifting work of the mold, increasing the production and operation costs of the equipment, and there is also a problem that it cannot clamp in time during operation, resulting in unstable factors.

[0004] Therefore, it is necessary to provide a new automated continuous production process for large hot-dip galvanized alloy ingots to solve the above technical problems. Summary of the Invention

Detailed implementation manners

[0036] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0038] Please refer to Figures 1 to 9, An automated continuous production process for hot-dip galvanized alloy ingots provided by an embodiment of the present invention includes:

[0039] 1), melting zinc blocks into zinc liquid using an electric furnace and then flowing it into the inner side of the transfer ladle;

[0040] 2), adding alloy to the inner side of the transfer ladle and stirring it with the zinc liquid;

[0041] 3), flowing the zinc alloy liquid onto the mold 102 on the disk ingot casting machine 101 for pouring;

[0042] 4), after the pouring is completed, using the skimming robot 103 to remove the slag on the zinc alloy liquid in the mold 102, and then the disk ingot casting machine 101 continues to rotate the mold 102 to the blanking station of the mold 102;

[0043] 5), using the gantry moving device 104 at the blanking station on the disk ingot casting machine 101 to move the mold 102 together with the ingot onto the outgoing conveyor line 107 and convey it to one side of the automatic demolding machine. During the conveying process, the ingot is heated and cooled in sequence using the heating device 105 and the cooling device 106;

[0044] 6), using the gantry moving device 104 on one side of the automatic demolding machine to convey the mold 102 loaded with the ingot onto the moving trolley 108, moving the mold 102 through the moving trolley 108 to the automatic demolding machine 109 to demold the ingot, and then the moving trolley 108 moves the empty mold 102 back to its original position. Again, using the gantry moving device 104 on one side of the automatic demolding machine to convey the empty mold 102 onto the return conveyor line 1010 and convey it to one side of the disk ingot casting machine 101, and then using the gantry moving device 104 on one side of the disk ingot casting machine 101 to move the empty mold 102 onto the disk ingot casting machine 101;

[0045] Among them, the gantry moving device 104 in step 5) and step 6) is composed of a main frame 1, two moving boxes 2 that are sequentially slidably connected to the main frame 1, a lifting mechanism 3 installed at the bottom of the moving box 2, a lifting plate 4 installed at the moving end of the lifting mechanism 3, a grasping mechanism 5 symmetrically installed on the lifting plate 4, and a driving mechanism 6 installed on the two moving boxes 2 for driving the two moving boxes 2 to move simultaneously. The grasping mechanism 5 is composed of a grasping component 51 fixed on the lifting plate 4 and a matching component 52 fixed on the top of the mold 102. Slide rails 7 are symmetrically fixed at the top of the main frame 1, and slide bars 8 are symmetrically fixed at the bottom of the moving box 2. The slide bars 8 are slidably connected to the outer wall of the slide rails 7.

[0046] Compared with the prior art, the present application realizes the effect of simultaneously transferring the mold 102 on the delivery conveyor line 107 to the mobile cart 108 and moving the mold 102 on the mobile cart 108 to the return conveyor line 1010 by setting two groups of mobile boxes 2, thereby greatly further improving the production efficiency. The clamping mechanism 5 set up makes the action of clamping and putting down the mold 102 mechanically linked with the lifting and lowering of the lifting plate 4, and there is no need to set up a separate driving device to drive the clamping and putting down work, thereby improving the stability and timeliness of the clamping and putting down work of the mold 102, avoiding the time difference between clamping and putting down, and since there is no need to set up a separate power driving device, the production and operation costs of the equipment are greatly reduced.

[0047] The driving mechanism 6 includes a connecting plate 61, a motor 62, a gear 63 and a rack 64. Two connecting plates 61 are symmetrically fixed between the two moving boxes 2, and a motor 62 is fixed on the top of one of the connecting plates 61. The motor 62 is a reduction motor 62. A gear 63 is fixed on the output end of the motor 62. A rack 64 is fixed on the outer surface of one side of the upper end of the main frame 1. The gear 63 is meshed and connected with the rack 64. The lifting mechanism 3 includes a hydraulic cylinder 31, a lower rotating rod 32 and an upper rotating rod 33. A hydraulic cylinder 31 is fixed to the middle part of the moving box 2. The protruding end of the hydraulic cylinder 31 is fixed to the top of the lifting plate 4. The four corners of the top of the lifting plate 4 are rotatably connected to the lower rotating rod 32 through an axle pin. The upper end of the lower rotating rod 32 is rotatably connected to the upper rotating rod 33 through an axle pin. The top of the upper rotating rod 33 is rotatably connected to the outer wall of the moving box 2 through an axle pin.

[0048] The cooperation of the driving mechanism 6 and the lifting mechanism 3 can complete the movement of the lifting plate 4, ensuring that the lifting plate 4 moves to the position corresponding to the delivery conveyor line 107, the return conveyor line 1010 and the mobile trolley 108. In the initial state shown in the figure, the lifting plate 4 is lowered by driving the hydraulic cylinder 31 to extend, and the mold 102 is automatically grabbed by the grabbing mechanism, and then the hydraulic cylinder 31 is driven to contract to drive the lifting plate 4 to rise, and then the motor 62 can be driven to rotate, driving the gear 63 to rotate, and the gear 63 drives the rack 64 to make the two mobile boxes 2 slide horizontally, so that the fully loaded mold 102 is moved to the top of the mobile trolley 108, and the empty mold 102 is moved to the return conveyor line 1010, and then the hydraulic cylinder 31 is extended again to put down the mold 102, and then the lifting plate 4 is raised and the motor 62 is driven again to reverse the motor 62, so that the lifting plate 4 is reset to prepare for the next conveying work.

[0049] The grasping component 51 includes a sleeve 511, a locking block 512, a support sleeve 513 and a spring 514. The bottom of the lifting plate 4 is symmetrically fixed with the sleeve 511. The locking block 512 is symmetrically and slidably connected to the side wall of the sleeve 511 through a sliding hole. Support sleeves 513 are symmetrically fixed on both sides of the lifting plate 4. One end of the locking block 512 is slidably connected to the inner wall of the support sleeve 513. The lower part of the end of the locking block 512 located inside the sleeve 511 is inclined. A spring 514 is sleeved on the end of the locking block 512 away from the sleeve 511. One end of the spring 514 is fixed to the outer wall of the locking block 512, and the other end of the spring 514 is fixed to the outer wall of the support sleeve 513. The matching component 52 includes a pull rod 521, a lifting block 522, a transition ring 523 and a limiting strip 524. Pull rods 521 are symmetrically fixed on the top of the mold 102. The lifting block 522 is fixed on the top of the pull rod 521. The lifting block 522 is frustum-shaped. The upper end of the pull rod 521 is slidably connected to the transition ring 523. The transition ring 523 is an inverted frustum-shaped. Limiting strips 524 are symmetrically fixed on the outer wall of the lower end of the pull rod 521. The bottom of the transition ring 523 contacts the top of the limiting strip 524. A chamfer is provided at the intersection of the hole and the lower end face of the sleeve 511, which is more conducive to the insertion of the sleeve 511 to the outside of the lifting block and the transition ring 523. The outer diameter of the top surface of the transition ring 523 is larger than the outer diameter of the bottom of the lifting block 522. The limiting strip 524 and the pull rod 521 are integrally formed.

[0050] After the positions of the lifting plate 4 and the template are aligned, drive the lifting plate 4 to descend until the sleeve 511 is sleeved outside the lifting block 522. Then, as the sleeve 511 continues to descend, the inclined surface of the locking block 512 is squeezed and slides inwards by the lifting block 522. Then, as the sleeve 511 continues to descend, after the locking block 512 passes over the lifting block 522, it is reset under the action of the resilience of the spring 514. The locking block 512 is stuck at the bottom of the lifting block 522. Then, the lifting plate 4 can be driven to rise, so that the locking block 512 drives the lifting block 522, thereby lifting the entire mold 102 upwards to complete the work of removing the mold 102. When it is necessary to lower the mold 102, drive the lifting plate 4 to descend. After the template descends in place, the sleeve 511 continues to descend, so that the inclined surface of the locking block 512 contacts the transition ring 523. Then, blocked by the transition ring 523, the locking block 512 is forced to slide and give way again until the locking block 512 passes over the top surface of the transition ring 523. Under the elastic force of the spring 514, the locking block 512 abuts against the lower outer wall of the transition ring 523. Then, the lifting plate 4 can be driven to rise. After that, the locking block 512 can push the transition ring 523 to slide upwards until the transition ring 523 contacts the bottom of the lifting block 522. After that, the transition ring 523 cannot continue to move upwards, while the locking block 512 moves upwards along the outer wall of the transition ring 523, and the locking block 512 gradually contracts and gives way. Finally, the locking block 512 passes over the transition ring 523 to a position above the bottom surface of the lifting block 522. Then, the locking block 512 continues to move upwards and will not get stuck with the lifting block 522, so that the sleeve 511 is separated from the pull rod 521 to complete the work of lowering the mold 102.

[0051] The circuits and controls involved in the present invention are all prior arts and will not be elaborated here.

[0052] The above are only embodiments of the present invention and do not limit the patent scope of the present invention accordingly.
