Description

Technical Field

[0001] The present application relates to the technical field of string knobs, and in particular to a flexible casting production line of coated sand. Background Art

[0002] With the advancement of production technology, the casting production mode has shifted to a more automated assembly line production mode, and its production efficiency, quality and cost have been greatly improved compared with the traditional production mode.

[0003] In the prior art, as shown in the attached Figure 1 As shown, in the existing industrial casting automated production line 17, each production step is connected in series through a transmission device to form a reciprocating production line, and the internal steps are closely connected and coordinated to achieve efficient production. However, between the single-line series production steps, if one of the links fails, or the processing and production of one of the links takes a long time, the upstream production steps and the downstream production steps have to stop and wait. For example, when the sand mold shell is set in the casting box, there is a lack of positioning device, and it is easy to tip over or overturn during the casting of molten steel. After that, the whole production line needs to be stopped and cleaned again, which greatly reduces the efficiency. Summary of the invention

[0004] In view of the above problems, the present application proposes a coated sand flexible casting production line, which realizes the positioning and stabilization function of the sand mold shell placed in the casting box by arranging a certain number of small steel balls or a smaller and more numerous steel sand in the casting box; the coated sand flexible casting production line is specifically realized by the following technical solutions:

[0005] A coated sand flexible casting production line comprises: a hoisting device, a track, a power device, a casting box, a sand mold shell and a box turner, wherein the hoisting device and the box turner are both connected to the track, the power device is transmission-arranged at various parts of the track, the casting box is arranged on the track, the sand mold shell is arranged in the casting box, and a positioning piece for stabilizing the sand mold shell is arranged in the casting box.

[0006] It is further configured that the positioning member is configured as two or more small steel balls. Through this configuration, the small steel balls fill the gap between the casting box and the sand mold shell to make the whole more stable, and the small steel balls are easier to collect and clean than steel sand.

[0007] It is further arranged that the small steel ball is arranged under the sand mold shell to control the height of the sand mold shell in the casting box. Through this arrangement, it is convenient to control the height of the sand mold shell placed in the box.

[0008] Further setting: The small steel balls also cover and surround the outer periphery of the sand mold shell, which is used to control the stable position of the sand mold shell in the pouring box. Through this setting, the spatial position of the sand mold shell placed in the box is stabilized, making the whole more stable.

[0009] Further setting: The track includes a conveying track and a return track. Both the conveying track and the return track are set to be multiple, and the multiple conveying pipelines and multiple return tracks are arranged in parallel. And a transfer track is arranged between the conveying track and the return track, and is connected in parallel through the transfer track. Through this setting, each conveying track will surely be adjacent to a return track, shortening the distance for the transfer vehicle to transfer an object from the conveying track to the return track, and improving the overall production efficiency of the production line.

[0010] Further setting: The transfer track includes a front transfer track and a rear transfer track. Both the front transfer track and the rear transfer track are perpendicular to the conveying pipeline and the return track. And the front transfer track is connected to the front ends of the conveying pipeline and the return track, and the rear transfer track is connected to the rear ends of the conveying track and the return track, so that the front and rear ends of each conveying track and return track are respectively connected together by the front transfer track and the rear transfer track to form a set of production loops. Through this setting, a loop is formed between the transfer track and the conveying track and the return track, facilitating the return use of the pouring box, realizing cyclic production, and improving production efficiency.

[0011] Further setting: It also includes a transfer vehicle, which is arranged on the transfer track, and the transfer vehicle carries the pouring box and can move along the extending direction of the transfer track. Through this setting, the transfer function of the pouring box between the conveying track, the return track and the pouring track is realized.

[0012] Further setting: It also includes a pouring track. The pouring track is set to be multiple and the pouring track is parallel to the conveying track and the return track. One end of the pouring track is connected to the other side of the front transfer track relative to the conveying track and the return track, and a steelmaking furnace for storing molten steel is arranged at the other end of the pouring track. Through this setting, the pouring box can efficiently receive the pouring of the molten steel in the steelmaking furnace, and multiple steelmaking furnaces and multiple pouring tracks greatly improve the pouring efficiency.

[0013] In summary, for the coated sand flexible casting production line, by setting a certain number of small steel balls or more steel sands with smaller volume in the pouring box, the positioning and stabilizing function of the sand mold shell placed in the pouring box is realized.

[0024] Please refer to Figures 2 to 3 , in this embodiment, the positioning members are set as more than two small steel balls; the small steel balls are arranged under the sand mold shell to control the height of the sand mold shell in the pouring box; the small steel balls also cover and surround the outer periphery of the sand mold shell to control the position stability of the sand mold shell in the pouring box. In addition, it should be noted that the small steel balls mainly play a role in stabilizing the sand mold shell. Due to the round outer surface of the steel balls, the advantage is that they are round and not easy to scratch the sand mold shell, and the disadvantage is that they are difficult to collect when they fall and roll. In addition, steel sand or square steel blocks can also be used, etc. Other shapes and other materials only need to meet the characteristics of small volume, high temperature resistance, and high hardness. The tracks include a conveying track and a return track. The conveying track and the return track are both set as multiple, and multiple conveying pipelines and multiple return tracks are arranged in parallel, and a transfer track is arranged between the conveying track and the return track and is connected in parallel through the transfer track; the transfer track includes a front transfer track and a rear transfer track. The front transfer track and the rear transfer track are both perpendicular to the conveying pipeline and the return track, and the front transfer track is connected to the front ends of the conveying pipeline and the return track, and the rear transfer track is connected to the rear ends of the conveying track and the return track, so that the front and rear ends of each conveying track and return track are respectively connected together by the front transfer track and the rear transfer track to form a set of production loops. Such a setting makes each conveying track necessarily adjacent to a return track, shortens the distance for the transfer vehicle to transfer the object from the conveying track to the return track, improves the overall production efficiency of the production line, and the transfer track forms a front-to-back connected circular production loop with the conveying track and the return track, greatly facilitating the reciprocating transportation of the pouring box on the track, reducing the handling work, and improving the work efficiency; there is also a transfer vehicle, the transfer vehicle is arranged on the transfer track, and the transfer vehicle carries the pouring box and can move along the extension direction of the transfer track; there is also a pouring track, the pouring track is set as multiple and the pouring track is parallel to the conveying track and the return track, one end of the pouring track is connected to the other side of the front transfer track opposite to the conveying track and the return track, and the other end of the pouring track is provided with a steelmaking furnace for storing molten steel.

[0025] Please refer to Figure 2 , in this embodiment, the overall production line work process is as follows: multiple pouring boxes are lined up on the conveying track( Figure 2There are 4 conveying tracks), and a box-pushing oil cylinder is arranged at the right end of the conveying track. Through the action of the box-pushing oil cylinder, the casting boxes arranged in line on the conveying track can move forward as a whole. A hoisting device is arranged on the conveying track to first place small steel balls at the bottom of the casting box to adjust the height of the casting to be suitable for pouring. For smaller castings, more small steel balls are laid, and for larger castings, fewer small steel balls are laid. Then, the sand mold shell is hoisted into the casting box, and small steel balls are laid around the sand mold shell. Except for the riser, the entire sand mold shell is buried in the small steel balls to reinforce the sand mold shell and prevent the sand mold shell from cracking when pouring molten steel.

[0026] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
