Description

Technical Field

[0001] This utility model relates to the technical field of gold target smelting equipment, and in particular to a gold target smelting equipment. Background Technology

[0002] Gold sputtering targets are a key material used to prepare thin films or coatings, providing a reliable material basis for the preparation of high-performance thin films and coatings. Gold sputtering targets are usually produced by melting and drawing high-purity metallic gold into gold sheets using a continuous casting machine, and then cutting and processing them.

[0003] The existing continuous casting machine (announcement number: CN207787644U) has at least the following drawbacks: After the metal material is melted into a sheet, the metal sheet is held by two feed rollers, and then the feed rollers rotate to pull out the metal sheet. However, since gold is a soft metal with extremely low hardness, it is very easy to undergo local plastic flow under the stress of roller pressing, which will form obvious indentations or scratches on the surface, thus affecting the production quality of gold sputtering material. Therefore, this utility model is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gold target smelting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gold target smelting device includes a continuous casting machine. The bottom surface of the casting furnace of the continuous casting machine is provided with a material pulling assembly for pulling gold plates. The material pulling assembly includes a material pulling bin located below the casting furnace of the continuous casting machine. A bidirectional lead screw is rotatably connected inside the material pulling bin. Two clamping seats are threadedly connected to the outer wall of the bidirectional lead screw. An extension hole is opened at the middle position of the top and bottom surfaces of the material pulling bin. The extension hole corresponds vertically to the position of the discharge hole at the bottom of the casting furnace of the continuous casting machine. A drive lead screw is rotatably connected between the casting furnace of the continuous casting machine and the base of the continuous casting machine. The material pulling bin is threadedly connected to the outer wall of the drive lead screw.

[0007] As a further embodiment of this utility model, a first motor is fixed on the left side of the feeding bin, the output shaft of the first motor extends into the interior of the feeding bin, and sprockets are fixed on both the output shaft end of the first motor and the outer wall of the bidirectional lead screw. The two sprockets are linked by a chain. A second motor is fixed on the top surface of the base of the continuous casting machine, and the output shaft of the second motor is fixed to the bottom end of the drive lead screw.

[0008] As a further embodiment of this utility model, four first support rods are fixed between the casting furnace of the continuous casting machine and the base of the continuous casting machine. The material pulling bin is slidably disposed with the outer wall of the first support rods. A second support rod is fixed on one side of the inside of the material pulling bin, and the clamping seat is slidably disposed with the outer wall of the second support rod.

[0009] As a further embodiment of this utility model, a guide bucket is fixed on the top surface of the material pulling bin, the guide bucket is connected to the extension hole, and the inner bottom surface of the material pulling bin is a conical structure.

[0010] As a further embodiment of this utility model, a tempered glass plate is embedded and fixed on the front side of the feeding bin.

[0011] As a further embodiment of this utility model, a water collection tank is placed on the top surface of the bottom surface of the continuous casting machine, and the water collection tank corresponds to the upper and lower positions of the extension hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting two clamping seats inside the feeding bin, the feeding template is clamped and fixed by the two clamping seats. After the feeding template cools and adheres to the gold sheet, the feeding bin is then driven to move down and pull the feeding template, thereby pulling the molten and cooled gold sheet out of the continuous casting machine. During this process, the clamping seats do not come into contact with the gold sheet and will not cause compression to the gold sheet, effectively preventing deformation of the gold sheet and indentation on the surface, thus increasing the production quality of gold sputtering targets.

[0022] like Figures 1-4 As shown, a gold target smelting device includes a continuous casting machine 1. The bottom surface of the casting furnace of the continuous casting machine 1 is provided with a material pulling assembly for pulling gold plates. The material pulling assembly includes a material pulling bin 2 located below the casting furnace of the continuous casting machine 1. A bidirectional lead screw 201 is rotatably connected inside the material pulling bin 2. Two clamping seats 202 are threadedly connected to the outer wall of the bidirectional lead screw 201. An extension hole 203 is opened at the middle position of the top and bottom surfaces of the material pulling bin 2. The extension hole 203 corresponds vertically to the position of the discharge hole at the bottom of the casting furnace of the continuous casting machine 1. A drive lead screw 204 is rotatably connected between the casting furnace of the continuous casting machine 1 and the base of the continuous casting machine 1. The material pulling bin 2 is threadedly connected to the outer wall of the drive lead screw 204.

[0023] like Figures 2-4As shown, in this embodiment, a first motor 205 is fixed on the left side of the feeding bin 2. The output shaft of the first motor 205 extends into the interior of the feeding bin 2. A sprocket is fixed to both the output shaft end of the first motor 205 and the outer wall of the bidirectional lead screw 201. The two sprockets are linked by a chain. A second motor 206 is fixed to the top surface of the base of the continuous casting machine 1. The output shaft of the second motor 206 is fixed to the bottom end of the drive lead screw 204. By passing the feeding template through the extension hole 203 and inserting it into the discharge port of the smelting furnace of the continuous casting machine 1, the first motor 205 is started. A sprocket is fixed to both the output shaft end of the first motor 205 and the outer wall of the bidirectional lead screw 201. Under the linkage of the two sprockets via the chain, the bidirectional lead screw 201 rotates. The clamping seat 202 and the bidirectional lead screw 204... Under the action of the threaded connection on the outer wall of the lead screw 201, the two clamping seats 202 move closer to each other and clamp the pulling template. Then, the second motor 206 is started to drive the lead screw 204 to rotate. Under the action of the threaded connection on the outer wall of the pulling chamber 2 and the drive lead screw 204, the pulling chamber 2 slowly descends and pulls the pulling template down. During this process, the gold plate that is adhered to the pulling template moves down with the pulling template. When the gold plate is completely pulled out, the clamping seats 202 can be released to remove the pulling template and the gold plate. Then, the gold plate is cut and processed to make a gold target. During the pulling of the gold plate, the clamping seats 202 do not contact the gold plate and will not squeeze the gold plate, effectively preventing the gold plate from deforming and the surface from being squeezed out, thus increasing the production quality of the gold target.

[0024] like Figures 2-4 As shown, in this embodiment, four first support rods 3 are fixed between the casting furnace of the continuous casting machine 1 and the base of the continuous casting machine 1. The material pulling bin 2 is slidably disposed on the outer wall of the first support rods 3. A second support rod 301 is fixed on one side of the inside of the material pulling bin 2. The clamping seat 202 is slidably disposed on the outer wall of the second support rod 301. The first support rods 3 can provide limiting support for the material pulling bin 2 during lifting and lowering. The second support rods 301 can provide limiting and support for the clamping seat 202 during movement.

[0025] like Figures 2-4 As shown, in this embodiment, a guide bucket 4 is fixed on the top surface of the material pulling bin 2. The guide bucket 4 is connected to the extension hole 203. The inner bottom surface of the material pulling bin 2 is a conical structure. By setting the guide bucket 4 and the inner bottom surface of the material pulling bin 2 to be a conical structure, when the cooling system of the continuous casting machine 1 continuously injects water along the outer wall of the gold sheet for cooling, the cooling water can flow along the outer wall of the gold sheet to the guide bucket 4, be guided by the guide bucket 4 to the interior of the material pulling bin 2, and then be discharged from the extension hole 203 along the conical structure of the material pulling bin 2.

[0026] like Figures 2-4As shown in this embodiment, a tempered glass plate 5 is embedded and fixed on the front side of the material pulling bin 2. By setting the tempered glass plate 5, it is convenient for the staff to observe the position of the material pulling template and to facilitate the material pulling template to enter the discharge port of the continuous casting machine 1.

[0027] like Figures 2-4 As shown in this embodiment, a water collection tank 6 is placed on the top surface of the bottom surface of the continuous casting machine 1. The water collection tank 6 corresponds to the vertical position of the extension hole 203. By setting the water collection tank 6, the coolant discharged from the cooling system of the continuous casting machine 1 can be collected in a centralized manner.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, when it is necessary to melt gold sheet material, the gold material is placed in the melting furnace of the continuous casting machine 1 and the parameters are set before melting begins. During this process, the pulling template is inserted through the extension hole 203 and connected to the discharge port of the melting furnace of the continuous casting machine 1. At this time, the first motor 205 is started. Sprockets are fixed at the output shaft end of the first motor 205 and the outer wall of the bidirectional lead screw 201. The two sprockets are linked by the chain, causing the bidirectional lead screw 201 to rotate. Under the action of the threaded connection between the clamping seat 202 and the outer wall of the bidirectional lead screw 201, the two clamping seats 202 move closer to each other and clamp the pulling template. Then, the second motor 206 is started to drive the drive screw 204 to rotate. Under the action of the threaded connection on the outer wall of 204, the pulling chamber 2 slowly descends and pulls the pulling template down. During this process, the gold sheet that is adhered to the pulling template moves down with the pulling template. During this process, the cooling system of the continuous casting machine 1 continuously injects water along the outer wall of the gold sheet for cooling. The cooling water flows along the outer wall of the gold sheet to the guide bucket 4 and is guided by the guide bucket 4 to the inside of the pulling chamber 2. Finally, it is discharged from the extension hole 203 into the inside of the water collection tank 6 for centralized collection. When the gold sheet is completely pulled out, the clamping seat 202 can be released to remove the pulling template and the gold sheet. Then, the gold sheet is cut and processed to make a gold target. During the pulling of the gold sheet, the clamping seat 202 does not contact the gold sheet and will not squeeze the gold sheet, effectively preventing the gold sheet from deforming and the surface from being squeezed out, thus increasing the production quality of the gold target.
