Description

Technical Field

[0001] This utility model relates to the field of metal ingot technology, specifically to a metal ingot cold shut and impurity grinding device. Background Technology

[0002] Cold shuts are a very common surface defect in metal ingots cast using the conventional direct water-cooling casting method. The surface typically shows joints where metal flows meet or overlap without fusion, with smooth edges at the junctions. Cold shuts occur because the meniscus of the liquid phase is retained on the ingot surface due to insufficient molten material replenishment. Rapid cooling, unstable liquid levels, and low casting speeds and temperatures make this process highly susceptible to cold shuts. Furthermore, impurities in the metal also become visible on the ingot surface, causing roughness and unevenness, affecting the ingot's smoothness. Therefore, grinding is necessary to eliminate cold shuts and impurity defects. However, existing grinding equipment can only grind one surface (the top) of the ingot simultaneously, making it inefficient and impacting the ingot processing progress. Utility Model Content

[0003] In order to overcome the problems existing in the background art, the present invention provides a metal ingot cold shut and impurity grinding device to solve the technical problem that the existing grinding device in the background art can only grind one surface of the ingot at the same time when grinding the surface of the ingot, and cannot grind multiple surfaces at the same time, thus resulting in low efficiency and affecting the ingot processing progress.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A cold shut and impurity grinding device for metal ingots includes a machine body 1 and a top grinding wheel assembly 2 mounted on the machine body 1; it also includes side grinding components 3 mounted on both sides of the machine body 1. The side grinding components 3 include grinding wheels 4, a transverse moving mechanism 5, a lifting mechanism 6, and a hidden groove 7. The grinding wheels 4 are mounted at the end of the transverse moving mechanism 5, the transverse moving mechanism 5 is mounted at the upper end of the lifting mechanism 6, the lifting mechanism 6 is mounted at the bottom of the hidden groove 7, and the hidden groove 7 is fixedly connected to the side wall of the machine body 1.

[0006] Preferably, the grinding wheel 4 is rotatably mounted in the mounting groove 41 provided at the end of the transverse moving mechanism 5, and is connected to the motor I 42 mounted on the transverse moving mechanism 5 via gear 43.

[0007] Preferably, the lateral movement mechanism 5 includes a telescopic rod 51, a lead screw I 52, and a motor II 53. The grinding wheel 4 is rotatably installed in the mounting groove 41 opened at the end of the telescopic rod 51. The motor I 42 is installed on the telescopic rod 51. The rear end of the telescopic rod 51 is slidably inserted into the sliding hole 54 opened in the upper side wall of the lifting mechanism 6 and is threadedly connected to the lead screw I 52 rotatably installed in the sliding hole 54. The lead screw I 52 is drively connected to the motor II 53 installed on the side wall of the lifting mechanism 6.

[0008] Preferably, the lifting mechanism 6 includes a lifting column 61, a support sleeve 62, a lead screw II 63, and a motor III 64; the lower end of the support sleeve 62 is fixedly installed at the bottom of the hidden groove 7, the lifting column 61 is lifted and sleeved in the support sleeve 62, and is threadedly connected to the lead screw II 63 installed at the bottom of the support sleeve 62, the motor III 64 is installed at the bottom of the hidden groove 7, and is connected to the lead screw II 63 via belt drive, the belt passes through the through hole 65 provided in the side wall of the support sleeve 62, and the telescopic rod 51 is installed in the sliding hole 54 opened in the side wall of the lifting column 61.

[0009] Preferably, the upper end of the hidden groove 7 is hinged with a cover plate 71 that can cover the upper opening of the hidden groove 7.

[0010] The beneficial effects of this utility model are as follows: This utility model, through the side grinding components set on both sides of the machine body, can simultaneously grind both sides of the ingot, while the top grinding wheel unit grinds the top surface of the ingot. Thus, this device can simultaneously grind the top surface and both sides of the ingot, avoiding multiple disassembly and assembly of the ingot, reducing the number of disassembly and assembly times, improving the grinding efficiency for defects such as cold shuts and impurities in the ingot, and accelerating the ingot processing progress. Furthermore, the side grinding components can be moved into a hidden slot for concealment via a lateral moving mechanism and a lifting mechanism. The side grinding components 3 can be selected for use depending on the actual situation. When only one surface needs to be ground, the side grinding components can be stored away, and only the top grinding wheel unit is needed for grinding, increasing the applicability of this device.

[0016] like Figure 1-4 As shown, this utility model provides a metal ingot cold shut and impurity grinding device, including a machine body 1 and a top grinding wheel unit 2 installed on the machine body 1; it also includes side grinding components 3 installed on both sides of the machine body 1. The side grinding components 3 include grinding wheels 4, a transverse moving mechanism 5, a lifting mechanism 6, and a hidden groove 7; the grinding wheels 4 are installed at the end of the transverse moving mechanism 5, the transverse moving mechanism 5 is installed at the upper end of the lifting mechanism 6, the lifting mechanism 6 is installed at the bottom of the hidden groove 7, and the hidden groove 7 is fixedly connected to the side wall of the machine body 1. In use, the ingot is first installed on the magnetic platform of the working platform of the machine body 1. Then, the top grinding wheel unit 2 is operated to contact the upper surface of the ingot. The specific structure and working principle of the top grinding wheel unit 2 are existing technologies and will not be described in detail. Then, the grinding wheel 4 is moved and lifted from the hidden slot 7 by the transverse moving mechanism 5 and the lifting mechanism 6, and moves to contact the side plate of the ingot. The grinding wheel 4 rotates, and then the ingot is slowly moved laterally, thereby grinding the top surface and two sides of the ingot simultaneously. The specific working principle of the transverse movement of the ingot on the working platform of the machine body 1 is existing technology and will not be described in this application. The device can simultaneously grind the top surface and two sides of the ingot, avoiding multiple disassembly and assembly of the ingot, reducing the number of disassembly and assembly times, improving the grinding efficiency of defects such as cold shuts and impurities in the ingot, and speeding up the ingot processing progress. The side grinding component 3 can also be moved to the hidden slot 7 for concealment by the transverse moving mechanism 5 and the lifting mechanism 6. The side grinding component 3 can be selected for use or not according to the actual situation. When only one surface needs to be ground, the side grinding component 3 can be stored, and only the top grinding wheel unit 2 can be used for grinding, which increases the application range of the device.

[0017] The grinding wheel 4 is rotatably mounted in the mounting groove 41 at the end of the transverse moving mechanism 5, and is connected to the motor I 42 mounted on the transverse moving mechanism 5 via gear 43. When the grinding wheel 4 is working, the motor I 42 drives the grinding wheel 4 to rotate through the gear 43, thereby grinding the active surface.

[0018] The lateral movement mechanism 5 includes a telescopic rod 51, a lead screw I 52, and a motor II 53. The grinding wheel 4 is rotatably installed in the mounting groove 41 at the end of the telescopic rod 51. The motor I 42 is installed on the telescopic rod 51. The rear end of the telescopic rod 51 is slidably inserted into a sliding hole 54 on the upper side wall of the lifting mechanism 6, and is threadedly connected to the lead screw I 52 rotatably installed in the sliding hole 54. The lead screw I 52 is drively connected to the motor II 53 installed on the side wall of the lifting mechanism 6. When the lateral movement mechanism is working, the motor II 53 drives the lead screw I 52 to rotate threadedly in the telescopic rod 51, thereby driving the telescopic rod 51 to move in the sliding hole 54 on the lifting mechanism 6, thereby driving the grinding wheel 4 at the end of the telescopic rod 51 to move laterally and contact the side wall of the ingot, thereby grinding the side wall of the ingot.

[0019] The lifting mechanism 6 includes a lifting column 61, a support sleeve 62, a lead screw II 63, and a motor III 64. The lower end of the support sleeve 62 is fixedly installed at the bottom of the hidden groove 7. The lifting column 61 is lifted and sleeved in the support sleeve 62 and threadedly connected to the lead screw II 63 installed at the bottom of the support sleeve 62. The motor III 64 is installed at the bottom of the hidden groove 7 and connected to the lead screw II 63 via belt drive. The belt passes through a through hole 65 provided in the side wall of the support sleeve 62. The telescopic rod 51 is installed in a sliding hole 54 opened in the side wall of the lifting column 61. When the lifting mechanism 6 is working, the motor III 64 drives the lead screw II 63 to rotate threadedly in the lifting column 61 via belt drive, thereby driving the lifting column to rise in the support sleeve 62, thereby driving the grinding wheel 4 to rise. Then, driven by the transverse movement mechanism 5, the grinding wheel 4 moves laterally to contact the side wall of the ingot, thereby grinding the side wall of the ingot.

[0020] The upper end of the hidden groove 7 is hinged with a cover plate 71 that can cover the upper opening of the hidden groove 7. When the side grinding assembly 3 is not in use, the grinding wheel 4 is stored in the hidden groove 7 by means of the lifting mechanism 6 and the lateral moving mechanism 5, and then the cover plate 71 is placed on the upper end of the hidden groove 7, thereby storing and hiding the side grinding assembly 3 to avoid affecting the handling operation of the workpiece.

[0021] Work process:

[0022] In use, the ingot is first installed on the working platform of the machine body 1. Then, the top grinding wheel unit 2 is operated to contact the upper surface of the ingot. The specific structure and working principle of the top grinding wheel unit 2 are existing technologies and will not be described in detail. Then, the grinding wheel 4 is moved and lifted from the hidden slot 7 by the lateral moving mechanism 5 and the lifting mechanism 6, and moves to contact the side plate of the ingot. The grinding wheel 4 rotates, and then the ingot is slowly moved laterally, thereby grinding the top surface and two sides of the ingot simultaneously. The specific working principle of the lateral movement of the ingot on the working platform of the machine body 1 is existing technology and will not be described in detail in this application. Description: This device can simultaneously grind the top surface and two sides of the ingot, avoiding multiple disassembly and assembly of the ingot, reducing the number of disassembly and assembly times, improving the grinding efficiency for defects such as cold shuts and impurities in the ingot, and accelerating the ingot processing progress; the side grinding component 3 can also be moved to the hidden slot 7 for concealment by the transverse moving mechanism 5 and the lifting mechanism 6. The side grinding component 3 can be selected for use or not according to the actual situation. When only one surface needs to be ground, the side grinding component 3 can be stored, and only the top grinding wheel unit 2 can be used for grinding, which increases the application range of the device.
