Description

Technical Field

[0001] This invention relates to the field of crystallizer technology, specifically to a manufacturing process for ultra-large-scale crystallizer copper tubes. Background Technology

[0002] Crystallizer copper tubes are a type of material used to manufacture crystallizers, typically used in laboratories or industrial production. They possess excellent thermal conductivity and corrosion resistance. Current technologies for producing ultra-large crystallizer copper tubes involve plate rolling and welding or ring forming. Copper tubes produced by plate rolling and welding or ring forming suffer from insufficient internal material grain size and numerous weld pores. Additionally, the copper tubes exhibit overall shrinkage and are prone to cracking during use, thereby reducing their overall service life. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a manufacturing process for ultra-large-scale crystallizer copper tubes, thereby solving the problems of insufficient grain size in the internal material structure, numerous welding pores, overall shrinkage and loosening of the copper tube, and easy cracking during use, which in turn reduces the overall service life of the copper tube.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a manufacturing process for an ultra-large specification crystallizer copper tube, wherein the manufacturing process for the ultra-large specification crystallizer copper tube is as follows: S1. Prepare the electrolytic copper ingot material for processing copper tube assemblies.

[0005] S2. Start the semi-continuous casting unit, put the copper ingot into the semi-continuous casting unit and form it through continuous casting. The weight of the finished copper tube assembly is at least 5T.

[0006] S3. After the copper tube assembly processed by the semi-continuous casting unit is cooled, it is transported to the interior of the hydraulic press unit by a transport device. The hydraulic press unit has a processing extrusion force of at least 8000T and performs secondary extrusion processing on the copper tube assembly.

[0007] S4. After the copper tube assembly is processed by the hydraulic press, it is cooled and then extruded again by the extrusion press.

[0008] S5. The formed copper tube assembly is transported to the interior of the curved box-type heating furnace. The copper tube assembly is heated and processed by the curved box-type heating furnace. After processing, the copper tube assembly is rapidly cooled down by the curved box-type heating furnace. Then, the copper tube assembly is tempered and heated by the curved box-type heating furnace. Finally, the copper tube assembly is uniformly cooled down by the curved box-type heating furnace.

[0009] S6. The copper tube assembly, heated and cooled by the curved box-type heating furnace, is transported to the interior of the high-precision Fanuc gantry five-axis machining center. The copper tube assembly is then machined by the high-precision Fanuc gantry five-axis machining center to ensure that all dimensions of the machined copper tube fully meet the requirements of the drawings.

[0010] S7. The copper tube assembly, which has been machined by the high-precision Fanuc gantry five-axis machining center, is lifted by a crane and placed into the interior of an ultra-large automated electroplating tank. The workpiece is then electroplated using the ultra-large automated electroplating tank.

[0011] A semi-continuous casting unit is used for the continuous casting of copper tube assemblies.

[0012] The hydraulic press unit is used for the initial extrusion molding of copper tube assemblies.

[0013] The extrusion unit is used for secondary extrusion processing of copper tube assemblies.

[0014] Curved box-type heating furnace is used for heating and cooling copper tube assemblies.

[0015] The high-precision Fanuc gantry five-axis machining center is used for cutting and finishing copper tube assemblies.

[0016] An ultra-large automated electroplating tank is used for electroplating copper tube assemblies.

[0017] The ultra-large automated electroplating tank includes a box body, a load-bearing plate is slidably connected inside the box body, blocks are slidably connected at equal intervals on the top of the load-bearing plate, a short arm is fixedly connected to the bottom of the blocks, a diagonal rod is hinged to the bottom of the short arm, and a base is hinged to the bottom of the diagonal rod. The outside of the base is connected to the inside of the box body.

[0018] Preferably, the top of the load-bearing plate is provided with horizontal grooves at equal intervals. The inside of the horizontal grooves is slidably connected to the outside of the short arm. The horizontal grooves facilitate the transmission of the short arm and guide the short arm to make it move in a straight line.

[0019] Preferably, the end of the block furthest from the inside of the copper tube assembly is connected with bristles at equal intervals. The bristles are long polyimide bristles, which prevents the solution from affecting the bristles' ability to remove air bubbles.

[0020] Preferably, the load-bearing plate is a square plate, and the load-bearing plate is slidably connected to the box body. The load-bearing plate can be guided by the box body and then move linearly inside the box body.

[0021] Preferably, the bottom of the load-bearing plate is connected with springs at equal intervals, and the bottom of the springs is connected to the bottom of the box body. The springs can drive the load-bearing plate to return to its original position after movement.

[0023] Compared with the prior art, the present invention provides a manufacturing process for ultra-large crystallizer copper tubes, which has the following beneficial effects: The manufacturing process of this ultra-large crystallizer copper tube improves the density of the copper tube assembly and reduces problems such as shrinkage porosity and shrinkage voids in the copper tube assembly; The manufacturing process of this ultra-large crystallizer copper tube utilizes the powerful 8000T press of the hydraulic press unit to rapidly reverse-extrude and form the copper tube assembly before the temperature drops, ensuring that the copper tube assembly is free of cracks, has a uniform grain structure, and high surface hardness. The manufacturing process of this ultra-large crystallizer copper tube eliminates residual internal stress and improves processing accuracy during the processing of the copper tube assembly; The manufacturing process of this ultra-large crystallizer copper tube improves the accuracy and capability of the copper tube assembly through the ultra-large automated electroplating tank, ensuring electroplating requirements are met. The manufacturing process of this ultra-large crystallizer copper tube utilizes an ultra-large automated electroplating tank. During the electroplating process of the copper tube assembly, air bubbles generated on the outside of the copper tube assembly are automatically removed, preventing air bubbles from adhering to the outside of the copper tube assembly. This avoids air bubbles affecting the electroplating effect of the copper tube assembly and improves the quality of the finished copper tube assembly. Attached Figure Description

[0042] The interior of the transverse groove 721 is slidably connected to the exterior of the short arm 74.

[0045] The first step in this plan is to prepare the copper ingot material for processing copper tube assembly 1; Start the semi-continuous casting unit 2, put the copper ingot into the interior of the semi-continuous casting unit 2 and form it by continuous casting. The weight of the finished copper tube assembly 1 is at least 5T. After the copper tube assembly 1 processed by the semi-continuous casting unit 2 is cooled, it is transported to the interior of the hydraulic press unit 3 by a transport device. The processing extrusion force of the hydraulic press unit 3 is at least 8000T. The copper tube assembly 1 is subjected to secondary extrusion processing by the hydraulic press unit 3.

After the copper tube assembly 1 is heated and cooled by the curved box-type heating furnace group 5, it is transported to the interior of the high-precision Fanuc gantry five-axis machining center group 6.

The copper tube assembly 1, which has been machined by the high-precision Fanuc gantry five-axis machining center assembly 6, is lifted by a crane and placed into the interior of the ultra-large automated electroplating tank 7. The workpiece is then electroplated using the ultra-large automated electroplating tank 7. When the copper tube assembly 1 is lowered onto the top of the load-bearing plate 72 by the crane, the ultra-large automated electroplating tank 7 is activated to electroplat the copper tube assembly 1 through the internal solution. When the copper tube assembly 1 is lowered by the crane, it drives the load-bearing plate 72 to descend. The descending load-bearing plate 72 drives the inclined rod 75 to drive the short arm 74 to move. The moving short arm 74 drives the block 73 to move. The moving block 73 scrapes against the copper tube assembly 1 to remove the bubbles generated by the electroplating on the outside of the copper tube assembly 1. By repeatedly lifting and lowering the copper tube assembly 1 by the crane, the blocks 73 can clean all the bubbles on the outside of the copper tube assembly 1.
