Description

Technical Field

[0001] This utility model relates to the field of metal ingot forming technology, specifically to a slag removal device for metal ingots. Background Technology

[0002] Metal casting is the process of pouring molten metal into a mold and cooling it to form a solid shape. Smelting is a fundamental step in metal processing. Through processes such as melting and purification, liquid metal that meets the requirements is obtained. The qualified liquid metal is poured into a specific mold and then solidified by natural or forced cooling to form a metal ingot of a predetermined shape. After solidification, the ingot is demolded and impurities on its surface are cleaned.

[0003] To prevent oxide slag and molten slag from appearing on the surface of the molten metal ingot after casting, it is necessary to remove the oxide slag and molten slag floating on the surface of the molten metal in the mold, thereby avoiding quality defects in the cast metal ingot. Current technology for removing oxide slag and molten slag from the surface of molten metal typically involves manual removal using a handheld net. This method is physically demanding for workers, and due to the high temperature of the molten metal, splashing during the casting process can easily cause injury to workers. Summary of the Invention

[0004] This invention addresses the problems of high labor intensity and potential injury caused by splashing molten metal when manually removing oxide slag and molten slag from the surface of liquid metal in existing technologies. It provides a slag removal device for metal ingots that effectively removes oxide slag and molten slag from the surface of liquid metal while reducing the labor intensity of workers, preventing injury from splashing high-temperature molten metal, and ensuring worker safety.

[0005] To achieve the above objectives, the technical solution of this utility model is: a slag removal device for metal ingot casting, comprising a drive mechanism and a slag removal mechanism. The drive mechanism includes a support and a drive component disposed inside the support. The upper end of the drive component is hinged to the support and is used to drive the slag removal mechanism to rotate around the lower end of the support. The support is fixed to the end of a six-axis robot. The six-axis robot drives the slag removal mechanism to extend into the mold through the drive mechanism, thereby achieving the effect of the slag removal mechanism cleaning out the oxide slag and molten slag from the surface of the liquid metal. The drive component is used to drive the movement of the slag removal mechanism to throw out the oxide slag and molten slag removed by the slag removal mechanism.

[0006] The slag removal mechanism includes an elbow, a slag removal connecting plate, and a slag removal plate. The elbow has a "Z"-shaped structure, with its upper end hinged to the lower end of the driving component and the support. The lower end of the elbow is connected to the slag removal connecting plate. At least one slag removal plate is provided on the slag removal connecting plate, which includes a slag removal frame and a slag removal net disposed within the frame. The frame is connected to the connecting plate. The driving component drives the connecting plate via the elbow, causing it to move and eject the removed oxide slag and molten slag.

[0007] Furthermore, a connecting plate is fixedly installed on the top of the support, and a reinforcing plate located on one side of the drive component is also fixedly installed inside the support; an upper pin and a lower pin are respectively installed at the upper and lower ends inside the support. The connecting plate serves to connect the six-axis robot, and the reinforcing plate provides stable support for the support.

[0008] Furthermore, the driving component is a cylinder, with a lug plate connected to the top of the cylinder body and a fisheye connector connected to the end of the piston rod. The lug plate is rotatably sleeved on the upper pin shaft; the purpose of this is to facilitate the cylinder to drive the elbow seat to move.

[0009] Furthermore, a slot is provided at the upper end of the elbow seat, and a fixing pin is fixedly installed in the slot; the piston rod of the cylinder is hinged to the upper end of the elbow seat through a fisheye joint and a fixing pin, so that the piston rod of the cylinder can extend to drive the elbow seat to rotate.

[0010] Furthermore, the upper corner of the elbow seat is hinged to the support via a lower pin; the lower end of the elbow seat is detachably connected to the middle of the slag removal plate, enabling quick replacement of the slag removal plate, thereby enabling quick replacement of the slag removal plate.

[0011] Furthermore, the slag-removing connecting plate has a "U"-shaped structure, and the slag-removing plate is fixedly installed at the end of the slag-removing connecting plate. The movement of the slag-removing connecting plate drives the slag-removing plate to move simultaneously, so as to achieve the effect of the slag-removing plate removing oxide slag and molten slag from the surface of liquid metal or throwing out oxide slag and molten slag.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] This utility model has a reasonable structure and good performance. It can effectively remove oxide slag and molten slag from the surface of liquid metal, thereby avoiding the problem of substandard quality of the metal ingots after molding. At the same time, it replaces manual labor by having the functions of slag removal and slag throwing, which can effectively reduce the labor intensity of operators and prevent the splashing high-temperature liquid metal from causing injury to operators, thereby ensuring the safety of operators.

[0014] This invention connects to the end effector of a six-axis robot via a support. The six-axis robot extends a slag-removing mechanism into the mold, simulating manual operation to remove oxide and molten slag from the surface of the liquid metal using its slag-removing plate. This effectively cleans the molten metal surface of oxide and molten slag, reducing the labor intensity of operators. The six-axis robot arm can position the slag-removing plate downwards, and a cylinder drives the slag-removing plate via an elbow, thus throwing off the oxide and molten slag from the plate.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1-3 As shown, a slag removal device for metal ingots includes a drive mechanism and a slag removal mechanism. The drive mechanism includes a support 1 and a drive component disposed inside the support 1. The upper end of the drive component is hinged to the support 1 and is used to drive the slag removal mechanism to rotate around the lower end of the support 1. In this embodiment, the upper end of the support 1 is fixed to the end of a six-axis robot. The six-axis robot drives the slag removal mechanism to move through the drive mechanism, extending the slag removal mechanism into the mold to simulate the removal of oxide slag and molten slag from the surface of liquid metal by manual labor, thereby replacing manual slag removal. When the six-axis robot moves above the slag hopper, the robot arm rotates to make the slag removal mechanism face downwards, and the drive component drives the slag removal mechanism to rotate, achieving the effect of throwing out the oxide slag and molten slag on the slag removal mechanism.

[0021] The slag removal mechanism includes an elbow seat 3, a slag removal connecting plate 4, and slag removal plates. The elbow seat 3 has a "Z"-shaped structure. The upper end of the elbow seat 3 is hinged to the lower end of the driving component and the support 1. The lower end of the elbow seat 3 is connected to the slag removal connecting plate 4. At least one slag removal plate is provided on the slag removal connecting plate 4. The slag removal plate includes a slag removal frame 5 and a slag removal net 6 disposed in the slag removal frame 5. The slag removal frame 5 is connected to the slag removal connecting plate 4. In this embodiment, there are two slag removal plates on the slag removal connecting plate 4. The slag removal connecting plate 4 and the slag removal frame 5 are integrally formed. The slag removal net 6 is fixedly installed in the slag removal frame 5. The slag removal net 6 is used to remove oxide slag and molten slag from the surface of the liquid metal in the mold. The driving component drives the elbow seat 3 to rotate relative to the support 1. The elbow seat 3 drives the slag removal connecting plate 4 to rotate, so as to throw off the oxide slag and molten slag scooped up by the slag removal net 6.

[0022] A connecting plate 101 is fixedly installed on the top of the support 1, and a reinforcing plate 102 located on one side of the drive component is also fixedly installed inside the support 1; an upper pin 103 and a lower pin 104 are respectively provided at the upper and lower ends inside the support 1. In this embodiment, a strip-shaped opening for installing the drive component is opened on the support 1, the drive component is installed inside the strip-shaped opening, the connecting plate 101 is used for bolt connection with the end of the six-axis robot arm, and the reinforcing plate 102 plays a role in stabilizing and reinforcing the support 1.

[0023] The driving component is a cylinder 2. The top of the cylinder body of the cylinder 2 is connected to a lug plate 201, and the end of the piston rod is connected to a fisheye connector 202. The lug plate 201 is rotatably mounted on the upper pin 103. The lug plate 201 has a pin hole that matches the pin 103. The lug plate 201 is rotatably mounted on the pin 103 through the pin hole, so that the piston rod of the cylinder 2 can extend and retract, driving the elbow to move.

[0024] The elbow seat 3 has a slot 301 at its upper end, and a fixing pin 302 is fixedly installed in the slot 301. The piston rod of the cylinder 2 is hinged to the upper end of the elbow seat 3 through a fisheye connector 202 and the fixing pin 302. In this embodiment, the fisheye connector 202 cooperates with the fixing pin 302 so that the piston rod of the cylinder 2 can drive the elbow seat 3 to rotate when it extends or retracts.

[0025] The upper corner of the elbow seat 3 is hinged to the support 1 via a lower pin 104; the lower end of the elbow seat 3 is detachably connected to the middle of the slag removal plate 4. In this embodiment, a pin hole matching the lower pin 104 is provided at the corner of the elbow seat 3, and the lower end of the elbow seat 3 is detachably connected to the slag removal plate 4 via bolts and wing nuts, enabling quick replacement of the slag removal plate 4 and the slag removal plate.

[0026] The slag removal plate 4 has a "U" shaped structure. The slag removal plate is fixedly installed at the end of the slag removal plate 4, and there are two slag removal plates fixed on the slag removal plate 4.

[0027] The working principle of this utility model is as follows: The ingot casting machine drives the mold to move forward continuously.

Simulating manual labor, the slag removal net 6 of the slag removal plate removes the oxide slag and molten slag from the surface of the liquid metal in the mold. Then, the six-axis robot can move this device above the slag hopper, and the robotic arm of the six-axis robot rotates so that the slag removal net faces downward. Then, the cylinder is controlled to move. The piston rod of the cylinder drives the elbow seat 3 to rotate. The elbow seat 3 drives the slag removal plate 4 to move. The slag removal plate 4 drives the slag removal plate to move to throw off the oxide slag and molten slag on the slag removal net 6. The oxide slag and molten slag fall into the slag hopper and are collected by the slag hopper. Then, the six-axis robot drives this device to move to the initial position to perform the next slag removal action.
