Description

Technical Field

[0001] This utility model relates to the field of crystallizer copper tube processing and forming technology, specifically to a crystallizer copper tube forming device that reduces corner wear. Background Technology

[0002] The processing and forming of copper tubes for crystallizers is one of the important steps in the production of copper tubes for crystallizers. The processing and forming of copper tubes for crystallizers includes cold drawing, reverse extrusion forming, cutting and shaping, internal cavity shape processing, and surface treatment processes. Cold drawing involves repeatedly cold drawing oxygen-free copper tubes through a cold drawing machine to reduce the tube diameter and increase the strength and hardness of the copper tube. Cold drawing is a common method for forming copper tubes. It uses stretching and compression to make the copper tube reach the required size and shape. The cutting and shaping process is required after the copper tubes are cold drawn or reverse extruded. The copper tubes are cut to the required length, and the end faces of the copper tubes are ground and shaped to ensure that they meet the requirements of the continuous casting machine. Cutting and shaping equipment and grinding and shaping equipment are the most commonly used processing equipment in the cutting and shaping process.

[0003] In current technologies, grinding and forming equipment is used to grind the cut copper tubes to remove burrs or protrusions generated after cutting, thus ensuring that the cut copper tubes are smooth and free of protrusions. In this process, workers need to use hand-held grinders to grind the cut surfaces of the copper tubes flat, which makes the labor intensity of the workers relatively high and time-consuming. Therefore, a crystallizer copper tube forming device that reduces corner wear is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a crystallizer copper tube forming device that reduces corner wear. It has the advantage of facilitating efficient and automatic grinding of the cut copper tube, solving the problem of using grinding and forming equipment to grind the cut copper tube to remove burrs or protrusions after cutting, thus ensuring a smooth cut without protrusions. In this process, workers need to use a hand-held grinder to grind the cut surface of the copper tube flat, which results in high labor intensity and is time-consuming.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crystallizer copper tube forming device for reducing corner wear, comprising a grinding and forming fixture, a copper tube positioning platform provided on the grinding and forming fixture, a control machine platform provided on one side of the grinding and forming fixture, and a grinding structure and a control structure provided on the grinding and forming fixture.

[0006] The grinding structure includes an annular frame mounted on a grinding forming fixture. Two mounting frames are slidably installed inside the annular frame. A feed component for controlling the movement of the two mounting frames is provided on the annular frame. Grinding components for grinding burrs on the cross-section of copper tubes are fixedly installed inside the two mounting frames. Connecting blocks are fixedly installed on the back of the two mounting frames. A guide rod with one end penetrating through the two connecting blocks is fixedly installed between the inner top wall and the inner bottom wall of the annular frame.

[0007] Furthermore, the control structure includes a mounting platform fixedly installed on the top of the grinding and forming fixture, the annular frame being rotatably installed inside the mounting platform, an asynchronous motor being fixedly installed on one side of the mounting platform, and a transmission component for driving the annular frame to rotate being provided at one end of the asynchronous motor.

[0008] Furthermore, the copper tube positioning platform is fixedly installed on the top of the grinding and forming fixture, and the control machine is fixedly installed on the right side of the grinding and forming fixture.

[0009] Furthermore, the feeding assembly includes two electric push rods, and the top and bottom of the annular frame are provided with circular grooves. The two electric push rods are respectively fixedly installed inside the two circular grooves, and the telescopic ends of the two electric push rods are respectively fixedly connected to the two mounting frames.

[0010] Furthermore, both of the grinding components include a three-phase motor and a grinding head. The two three-phase motors are respectively fixedly installed inside the two mounting frames, and the two grinding heads are respectively fixedly installed on the outer surface of the output shafts of the two three-phase motors.

[0011] Furthermore, both connecting blocks have through holes inside, and one end of the guide rod passes through the two through holes. The inner walls of the two through holes are slidably connected to the outer surface of the guide rod.

[0012] Furthermore, the mounting platform has an internal mounting groove, and two bearings are fixedly mounted on the inner peripheral wall of the mounting groove. The outer peripheral wall of the annular frame is fixedly connected to the inner peripheral walls of the two bearings respectively.

[0013] Furthermore, the transmission assembly includes a bevel gear and a bevel gear ring, the outer surfaces of the bevel gear and the bevel gear ring meshing with each other, the bevel gear being fixedly mounted on the outer surface of the output shaft of the asynchronous motor, and the bevel gear ring being fixedly mounted on the outer peripheral wall of the annular frame.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This crystallizer copper tube forming device for reducing corner wear incorporates a grinding structure and a control structure. It utilizes a feeding assembly to control the movement of two grinding assemblies to opposite sides, thereby controlling the grinding heads in the two grinding assemblies to contact the copper tube cross-section. A three-phase motor controls the rotation of the grinding heads, allowing them to grind the copper tube cross-section. An asynchronous motor serves as the drive source, mechanically controlling the rotation of a ring frame, which in turn drives the two grinding assemblies to rotate synchronously, further controlling the synchronous rotation of the two grinding heads. This achieves efficient grinding of burrs and protrusions on the annular copper tube cross-section, replacing manual grinding. This not only reduces the labor intensity of workers but also improves grinding efficiency, enhancing the practicality of this crystallizer copper tube forming device for reducing corner wear.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This embodiment provides a crystallizer copper tube forming device for reducing corner wear. The device includes a grinding and forming fixture 1, a copper tube positioning platform 2, and a control platform 3 on one side of the grinding and forming fixture 1. The grinding and forming fixture 1 is equipped with a grinding structure and a control structure. The copper tube positioning platform 2 is fixedly installed on the top of the grinding and forming fixture 1, and the control platform 3 is fixedly installed on the right side of the grinding and forming fixture 1.

[0023] Example 1: Please refer to Figures 1 to 4 In this embodiment, the grinding structure includes an annular frame 41 mounted on the grinding forming fixture 1. Two mounting frames 42 are slidably installed inside the annular frame 41. A feed assembly 43 for controlling the movement of the two mounting frames 42 is provided on the annular frame 41. The feed assembly 43 includes two electric push rods. Circular grooves are provided at the top and bottom of the annular frame 41. The two electric push rods are respectively fixedly installed inside the two circular grooves. The telescopic ends of the two electric push rods are respectively fixedly connected to the two mounting frames 42, facilitating control of the two mounting frames 42 to move to opposite sides or away from each other. Both mounting frames 42 are fixedly installed with grinding components 44 for grinding burrs on the cross-section of copper tubes. Each grinding component 44 includes a three-phase motor and a grinding head. The two three-phase motors are fixedly installed inside the two mounting frames 42 respectively, and the two grinding heads are fixedly installed on the outer surface of the output shafts of the two three-phase motors respectively, so as to facilitate the rotation of the grinding heads by the three-phase motors and use the rotating grinding heads to grind the cross-section of copper tubes. A connecting block 45 is fixedly installed on the back of each of the two mounting frames 42. A guide rod 46 with one end penetrating through the two connecting blocks 45 is fixedly installed between the inner top wall and the inner bottom wall of the annular frame 41.

[0024] Both connecting blocks 45 have through holes inside, and one end of the guide rod 46 passes through the two through holes. The inner walls of the two through holes are slidably connected to the outer surface of the guide rod 46, thereby restricting the connecting blocks 45 to move up and down only on the outer surface of the guide rod 46, thus restricting the trajectory of the grinding assembly 44 to move up and down.

[0025] By adopting the above technical solution, the two electric push rods in the feed assembly 43 are activated, thereby controlling the two mounting frames 42 to move to opposite sides. This, in turn, controls the grinding heads in the two grinding assemblies 44 to contact the copper tube cross-section, starts the three-phase motor and drives the grinding heads to rotate, so that the rotating grinding heads grind the burrs on the copper tube cross-section. Then, the control structure drives the annular frame 41 to rotate, so that the rotating annular frame 41 drives the grinding heads in the grinding assembly 44 to rotate through the mounting frame 42, thereby using the two rotating grinding heads to grind and level the copper tube cross-section.

[0026] Example 2: Please refer to Figures 1 to 4In this embodiment, the control structure includes a mounting platform 47 fixedly installed on the top of the grinding and forming fixture 1. An annular frame 41 is rotatably installed inside the mounting platform 47 to facilitate the rotation of the annular frame 41. An asynchronous motor 48 is fixedly installed on one side of the mounting platform 47. One end of the asynchronous motor 48 is provided with a transmission assembly 49 for driving the annular frame 41 to rotate. The transmission assembly 49 includes a bevel gear and a bevel gear ring. The outer surfaces of the bevel gear and the bevel gear ring mesh with each other. The bevel gear is fixedly installed on the outer surface of the output shaft of the asynchronous motor 48, and the bevel gear ring is fixedly installed on the outer peripheral wall of the annular frame 41, so that the asynchronous motor 48 can drive the output shaft to rotate and use the bevel gear and the bevel gear ring in the transmission assembly 49 to drive the annular frame 41 to rotate inside the mounting platform 47.

[0027] The mounting platform 47 has an internal mounting groove, and two bearings are fixedly installed on the inner circumferential wall of the mounting groove. The outer circumferential wall of the annular frame 41 is fixedly connected to the inner circumferential walls of the two bearings respectively. The catfish uses the bearings to support the rotation of the annular frame 41.

[0028] By adopting the above technical solution, the output shaft is driven to rotate by the asynchronous motor 48, so that the rotating output shaft drives the ring frame 41 to rotate inside the mounting platform 47 through the bevel gear and bevel gear ring in the transmission assembly 49.

[0029] The working principle of the above embodiments is as follows:

[0030] In this crystallizer copper tube forming device for reducing corner wear, when in use, the two electric push rods in the feeding assembly 43 are activated, thereby controlling the two mounting frames 42 to move to opposite sides, thereby controlling the grinding heads in the two grinding assemblies 44 to contact the copper tube cross-section. The three-phase motor is started and drives the grinding heads to rotate, so that the rotating grinding heads grind the burrs on the copper tube cross-section. Then, the output shaft is driven to rotate by the asynchronous motor 48, so that the rotating output shaft drives the annular frame 41 to rotate inside the mounting platform 47 through the bevel gear and bevel gear ring in the transmission assembly 49. In turn, the rotating annular frame 41 drives the grinding heads in the grinding assembly 44 to rotate through the mounting frame 42, thereby using the two rotating grinding heads to grind and level the copper tube cross-section.
