Description

Technical Field

[0001] This utility model relates to the field of crystallizer copper tube technology, specifically a rapid unloading device for processing crystallizer copper tubes. Background Technology

[0002] The crystallizer copper tube is a core component of the continuous casting machine, responsible for the solidification and shaping of molten steel. The quality of the crystallizer copper tube significantly impacts not only the output and quality of the cast billet but also its service life. During continuous casting, the coating on the inner surface of the crystallizer copper tube comes into contact with the high-temperature molten steel, subjecting it to the combined effects of chemical corrosion, thermal erosion, and friction with the billet shell. This makes the crystallizer copper tube prone to thermal deformation and scratches on the surface coating, affecting the normal operation of the continuous casting machine, reducing casting efficiency, and deteriorating the quality of the cast billet.

[0003] During the cold rolling process of the crystallizer copper tube, a mandrel needs to be placed inside the copper tube for support and positioning. Due to the mechanical pressure, the mandrel is tightly attached to the inner wall of the copper tube, making it very troublesome to remove the mandrel. Currently, the unloading work is generally done manually, which is time-consuming and labor-intensive, thus reducing the convenience of unloading the crystallizer copper tube. Utility Model Content

[0006] Preferably, the limiting mechanism includes a limiting plate fixedly connected to the upper part of the ejector plate. A through ejector port is provided on one side of the limiting plate. Sliding grooves are provided on the inner walls of both sides of the ejector port. Two baffles slide in the cavities of the two sliding grooves respectively.

[0008] Preferably, the driving mechanism includes a threaded rod rotatably connected to the upper part of the device body, the ejector plate being threaded onto the outside of the threaded rod, a servo motor being mounted on the device body, the output shaft of the servo motor being fixedly connected to the end of the threaded rod, and the servo motor being electrically connected to a power source.

[0010] Preferably, the upper part of the device body has two first track grooves, and each of the two first track groove cavities is slidably connected to a first track block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application uses a material ejection plate and ejector rod to clamp the material. Compared with traditional material ejection devices, this structure is more convenient to use, and the material ejection process is very simple and convenient. Therefore, it reduces the labor intensity of workers and improves the working efficiency of copper tube processing in crystallizers.

[0014] 2. This application uses a limiting plate and a baffle. The limiting plate improves the stability of the baffle ejection. At the same time, the first bidirectional screw can also adjust the distance between the two baffles to adapt to different sizes of crystallizer copper tubes. It also ensures that the ejection position of the crystallizer copper tube is centered, which facilitates the precise docking of the crystallizer copper tube with the ejector rod. This improves the applicability and ejection stability of the ejection device for crystallizer copper tube processing.

This application incorporates a placement plate whose height can be adjusted according to the different sizes of crystallizer copper tubes, thereby centering the crystallizer copper tubes and placing them on the same horizontal line as the ejector rod. This avoids damage to the crystallizer copper tubes caused by misalignment of the ejector rod, thus further improving the stability and applicability of crystallizer copper tube unloading.

Detailed Implementation

[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] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a rapid unloading device for processing copper tubes in a crystallizer. It includes a device body 1, an unloading plate 3 slidably connected to the upper part of the device body 1, a drive mechanism 4 for adjusting the movement of the unloading plate 3, a first mounting plate 6 fixedly connected to the upper part of the device body 1, an ejector rod 7 fixedly connected to one side of the first mounting plate 6 located on the unloading plate 3, two baffles 5 on the upper part of the unloading plate 3, and a limiting mechanism 8 for stabilizing the baffles 5.

[0023] Place the crystallizer copper tube between the baffle 5 and the ejector rod 7, and place the core rod in the crystallizer copper tube between the two baffles 5, while the end of the ejector rod 7 abuts against the other end of the core rod. Then drive the ejector plate 3 to move towards the first mounting plate 6, so that the baffle 5 pushes the crystallizer copper tube away from the core rod.

[0024] Among them, the outer diameter of the ejector rod 7 is smaller than that of a typical core rod, which makes it easy to adapt to different sizes of crystallizer copper tubes.

[0025] like Figure 3 and Figure 4 As shown, the limiting mechanism 8 includes a limiting plate 801 fixedly connected to the upper part of the ejector plate 3. A through ejector port 802 is provided on one side of the limiting plate 801. Slide grooves are provided on both inner walls of the ejector port 802. Two baffles 5 slide in the cavities of the two slide grooves respectively. A first bidirectional screw 803 is rotatably connected between the inner walls of the two slide grooves. The two baffles 5 are threaded on the outer side of the two first bidirectional screws 803 respectively. Two mirror-symmetrical external threads are provided on the outer side of the first bidirectional screws 803. The two baffles 5 are threaded on the two external threads in the first bidirectional screws 803 respectively.

[0026] The top and bottom walls inside the chute are both formed with grooves, and the top and bottom of the baffle 5 slide in the cavities of the two grooves respectively.

[0027] The first bidirectional screw 803 is rotated according to the size of the crystallizer copper tube, so that the two baffles 5 are brought closer or further apart, and the distance between the two baffles 5 is such that the core rod can be placed, but the crystallizer copper tube cannot be placed. At this time, the end of the crystallizer copper tube abuts against the side wall of the baffle 5.

[0028] By rotating the first bidirectional screw 803, the first bidirectional screw 803 drives the two baffles 5 to interact.

[0029] like Figure 1 - Figure 4As shown, two mirror-symmetrically arranged moving rods 9 are slidably connected to the upper part of the ejector plate 3. A placement plate 10 is arranged above the moving rods 9. A cross assembly is arranged between the placement plate 10 and the two moving rods 9. The cross assembly includes inclined rods 11 that are intersected and staggered. The two ends of the inclined rods 11 are rotatably connected to the bottom of the placement plate 10 and the upper part of the moving rods 9, respectively. A second bidirectional screw 12 is rotatably connected to the upper part of the ejector plate 3. The two moving rods 9 are threaded on the outside of the second bidirectional screw 12. The outside of the second bidirectional screw 12 is provided with two mirror-symmetrical external threads. The two moving rods 9 are respectively threaded on the two external threads in the second bidirectional screw 12.

[0030] The second bidirectional screw 12 is rotated according to the size of the crystallizer copper tube, so that the two moving rods 9 move closer or further apart. At the same time, the placement plate 10 is raised and lowered by the cooperation of the cross assembly. The placement plate 10 supports the bottom of the crystallizer copper tube and lifts the crystallizer copper tube so that the center of the crystallizer copper tube is approximately on the same horizontal line as the center of the ejector rod 7, thereby increasing the stability of the ejector rod 7 ejecting the core rod.

[0031] like Figure 1 As shown, the drive mechanism 4 includes a threaded rod 13 rotatably connected to the upper part of the device body 1, a ejector plate 3 threadedly sleeved on the outside of the threaded rod 13, a servo motor 14 mounted on the device body 1, the output shaft of the servo motor 14 being fixedly connected to the end of the threaded rod 13, and the servo motor 14 being electrically connected to the power supply.

[0032] The servo motor 14 drives the threaded rod 13 to rotate, and the threaded rod 13 drives the ejector plate 3 to move towards the first mounting plate 6.

[0033] like Figure 1 and Figure 2 As shown, a second mounting plate 15 is installed on the upper part of the device body 1. A hydraulic cylinder 16 is provided on one side of the second mounting plate 15. A clamping plate 17 is fixedly connected to the output end of the hydraulic cylinder 16. Telescopic rods 2 are fixedly connected to the four corners of one side of the clamping plate 17. A telescopic groove is provided at the corresponding position of the second mounting plate 15 relative to the telescopic rod 2. The movable end of the telescopic rod 2 slides in the cavity of the telescopic groove.

[0034] The hydraulic cylinder 16 drives the clamping plate 17 to move towards the ejector rod 7, and the ejector rod 7 and the clamping plate 17 work together to clamp the two ends of the core rod, thereby increasing the stability of the copper tube unloading in the crystallizer.

[0035] like Figure 1 - Figure 4As shown, the upper part of the device body 1 has two first track grooves 19, and each of the two first track grooves 19 has a first track block 18 slidably connected in its cavity. The two first track blocks 18 are fixedly connected to the bottom of the ejector plate 3. The vertical cross section of the first track groove 19 is a convex cavity, and the vertical cross section of the first track block 18 is a convex structure.

[0036] The cooperation between the first track groove 19 and the first track block 18 can limit the range of motion of the ejector plate 3 and improve the stability of the ejector plate 3's movement.

[0037] like Figure 1 - Figure 4 As shown, the bottom of the moving rod 9 is fixedly connected to two second track blocks 21. The ejector plate 3 has a second track groove 20 at the corresponding position of each second track block 21. Each second track block 21 slides in the cavity of the four second track grooves 20. The vertical cross section of the second track groove 20 is a convex cavity, and the vertical cross section of the second track block 21 is a convex structure.

[0038] The cooperation of the second track groove 20 and the second track block 21 can limit the range of motion of the moving rod 9 and improve the stability of the moving rod 9.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
