Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a crystallizer copper tube extrusion and stretching machine. Background Technology

[0002] The copper tube of the crystallizer is a core component in the continuous casting process of steel. It is installed inside the crystallizer of the continuous casting machine and comes into direct contact with the high-temperature molten steel. It is responsible for the rapid cooling and initial solidification of the molten steel, and its performance directly affects the quality of the cast billet, production efficiency and equipment life.

[0003] In existing technologies, lubricant needs to be manually applied before expanding and extending the steel pipe. This is inefficient and makes it difficult to ensure the uniformity and integrity of the lubricant application. Areas that are missed or unevenly coated are prone to occur, leading to increased local frictional resistance, damage to the inner wall of the copper pipe, and affecting the quality of the finished product. Utility Model Content

[0004] This utility model discloses a crystallizer copper tube extrusion and stretching machine, which aims to solve the technical problems of low efficiency and difficulty in ensuring the uniformity and integrity of lubricant application by manual application.

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

[0006] A crystallizer copper tube extrusion and stretching machine includes a base;

[0007] An extruder body, wherein the extruder body is disposed on top of the base;

[0008] Mounting bracket, which is fixedly connected to the top of the base;

[0009] A hydraulic cylinder, which is fixedly connected inside the mounting base;

[0010] Mounting bracket, which is disposed on the top of the base;

[0011] The uniform operation module is located on the mounting base. The uniform operation module includes a fixed ring frame, which is fixedly connected to one side of the outer wall of the mounting base. A movable ring frame is movably connected to the side of the fixed ring frame away from the mounting base. An annular tube is fixedly connected to the movable ring frame. Multiple nozzles are equidistantly arranged on the annular tube.

[0012] The rinsing auxiliary module is located on the base and mounting bracket. It includes two fixed pipes, both fixedly connected to the top of the mounting bracket. Multiple spray arc pipes are fixedly connected to both fixed pipes at equal intervals, and multiple nozzles are circumferentially arranged on each spray arc pipe. The uniform operation module also includes a delivery pump, fixedly connected to the top of the mounting base. A delivery pipe is fixedly connected to the output end of the delivery pump, and the end of the delivery pipe away from the delivery pump is connected to an annular pipe. A liquid storage tank is fixedly connected to the top of the mounting base, and the input end of the delivery pump is connected to the liquid storage tank. A toothed ring is fixedly connected to the outside of the movable ring frame, and an electric telescopic rod is fixedly connected to the side of the fixed ring frame closest to the mounting base. A toothed rod is fixedly connected to the drive end of the electric telescopic rod, and the toothed rod meshes with the toothed ring.

[0013] By incorporating a uniform operation module, as the hydraulic cylinder extends, a delivery pump is activated to pump lubricant from the storage tank into the annular pipe via a delivery pipe, which is then sprayed out through nozzles. Simultaneously, an electric telescopic rod is activated to reciprocate the push-pull of the gear rack. Through the meshing of the gear rack and the gear ring, the movable ring frame and the annular pipe rotate reciprocally. This allows for continuous, all-around automatic spraying of the outer surface during the extension of the hydraulic cylinder, ensuring uniform lubricant coverage. This replaces manual brushing, improves work efficiency, and avoids damage to the inside of the copper pipe caused by uneven lubrication leading to increased local frictional resistance.

[0014] In a preferred embodiment, the rinsing auxiliary module further includes a suction pump, which is fixedly connected to the top of the base. A connecting pipe is fixedly connected to the output end of the suction pump, and a diverter pipe is fixedly connected to the end of the connecting pipe furthest from the suction pump. Both outlet ends of the diverter pipe are connected to corresponding fixed pipes. A water collection tank is provided above the base, and a condenser is provided on the water collection tank. A sliding groove is provided on the water collection tank, and a filter plate is slidably connected within the sliding groove. The input end of the suction pump is connected to the water collection tank. Multiple rotating holes are equidistantly provided on the mounting frame, and rotating rollers are rotatably connected within each of the multiple rotating holes. Two mounting holes are provided on the mounting frame, and hydraulic rods are fixedly connected within each of the two mounting holes. The drive ends of the two hydraulic rods are fixedly connected to the same upper pressure component, and a lower pressure component is fixedly connected to the mounting frame, located below the upper pressure component.

[0015] Equipped with a rinsing auxiliary module, the suction pump pumps clean water from the collection tank into the fixed pipes on both sides via connecting pipes and branch pipes. Then, the water enters the spray arc pipe and is sprayed onto the extruded thick-walled copper tube through the nozzles, allowing the water flow to cool the thick-walled copper tube evenly. At the same time, the water flow impacts the outside of the thick-walled copper tube, washing away surface impurities and scum. The rinsed water falls through the gaps between the rotating rollers, passes through the filter plate to remove impurities and scum, and returns to the collection tank. The condenser cools the water in the collection tank. The circulating water spray achieves uniform cooling and surface cleaning of the extruded copper tube. Meanwhile, the use of filter plate filtration and condenser cooling ensures the recycling of water resources.

[0016] As can be seen from the above, the crystallizer copper tube extrusion and stretching machine provided by this utility model can automatically spray the outer surface of the tube continuously and in all directions during the process of the hydraulic cylinder extending end, so that the lubricant is evenly covered, replacing manual brushing, improving work efficiency, and avoiding damage to the inside of the copper tube caused by uneven lubrication and increased local friction resistance.
