Description

Technical Field

[0001] The utility model relates to the technical field of in-furnace rollers, and particularly relates to an in-furnace roller for a quenching furnace. Background Art

[0002] A quenching furnace is a furnace for heating workpieces before quenching, mainly used in the heat treatment process of metal materials. By means of high-temperature heating and rapid cooling, the organizational structure of the material is changed to improve its hardness and strength. At the same time, internal stress is eliminated, and the toughness and durability of the material are improved.

[0003] The in-furnace roller is a key component in the quenching furnace. It is mainly used to support and convey workpieces during the quenching process to ensure that the workpieces can move stably during the heating and cooling processes. During the process of conveying the workpieces, the in-furnace roller will generate friction with the workpieces and will be slightly deformed. It is necessary to unload the in-furnace roller from the quenching furnace and perform grinding processing. At this time, a handling mechanism is required. Therefore, this application document provides an in-furnace roller handling device for a quenching furnace. Summary of the Utility Model

[0004] The utility model specifically adopts the following technical solutions to achieve the above purposes:

[0005] An in-furnace roller for a quenching furnace includes a roller body. Circular plates are respectively welded at both ends of the roller body. A connection mechanism is arranged on the circular plates. Left and right clamping plates are arranged outside the roller body. A bottom clamping mechanism is arranged at the bottom between the left and right clamping plates, and a top clamping mechanism is arranged at the top between the left and right clamping plates. The bottom clamping mechanism at the bottom and the top clamping mechanism at the top achieve multi-point clamping of the roller body, which can ensure that the roller body is firmly fixed during handling and reduce the risk of damage caused by shaking or slipping.

[0006] Further, the roller body is cylindrical, and being cylindrical is the main object to be clamped.

[0007] Further, clamping grooves are arranged on the left and right clamping plates, and the clamping grooves can clamp the roller body.

[0008] Further, fixing blocks are fixed on the left and right clamping plates, and hanging holes are symmetrically arranged on the fixing blocks, and the hanging holes facilitate handling.

[0009] Further, the connection mechanism includes a connection block fixedly installed on the circular plate, and a connection roller is welded on the connection block. The connection mechanism prevents loosening or falling off during use.

[0010] Further, the bottom clamping mechanism includes a left bottom plate fixed to the bottom of the left clamping plate and a right bottom plate fixed to the bottom of the right clamping plate. Symmetrically fixed on the left bottom plate are screw rods, and the screw rods pass through the right bottom plate and are threadedly connected with limiting nuts.

[0011] Further, the left bottom plate and the right bottom plate are arranged at the bottom of the roller body, and arranging them at the bottom of the roller body facilitates clamping.

[0012] Further, the top clamping mechanism includes a plurality of round holes provided on the left bottom plate and the right bottom plate. Inserted in the round holes are round rods, and both ends of the round rods pass through clamping plates. Threadedly connected to the ends of the round rods are abutting nuts, and adjustment holes are provided on the clamping plates.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, the two ends of the roller body are welded and fixed by round plates, which not only enhances the overall strength of the roller body but also makes it difficult for the roller body to deviate axially or radially during the handling process. The design of the left clamping plate and the right clamping plate, in cooperation with the bottom clamping mechanism at the bottom and the top clamping mechanism at the top, realizes multi-point clamping of the roller body, ensuring that the roller body is firmly fixed during the handling process, reducing the risk of damage caused by shaking or slipping. At the same time, the bottom clamping mechanism and the top clamping mechanism can be finely adjusted according to the actual size and shape of the roller body, improving the clamping accuracy and adaptability.

[0015] 2.

Detailed implementation mode

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] This application provides an in-furnace roller for a quenching furnace, mainly used to solve the problem that the in-furnace roller will rub against the workpiece and slightly deform, and it is necessary to remove the in-furnace roller from the quenching furnace and perform grinding processing. At this time, a handling mechanism is required, and the following technical solutions are provided and will be described in detail below:

[0024] Embodiment 1:

[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 shown, in some embodiments, it includes a roller body 1. Circular plates 2 are welded to both ends of the roller body 1. A connecting mechanism 3 is provided on the circular plates 2. A left clamping plate 4 and a right clamping plate 5 are arranged outside the roller body 1. A bottom clamping mechanism 6 is arranged at the bottom between the left clamping plate 4 and the right clamping plate 5, and a top clamping mechanism 7 is arranged at the top between the left clamping plate 4 and the right clamping plate 5. The roller body 1 is cylindrical. The bottom clamping mechanism 6 includes a left bottom plate 601 fixed to the bottom of the left clamping plate 4 and a right bottom plate 602 fixed to the bottom of the right clamping plate 5. Screw rods 603 are symmetrically and fixedly installed on the left bottom plate 601. The screw rods 603 penetrate through the right bottom plate 602 and are threadedly connected with limiting nuts 604. The left bottom plate 601 and the right bottom plate 602 are arranged at the bottom of the roller body 1. The top clamping mechanism 7 includes a plurality of circular holes 701 provided on the left bottom plate 601 and the right bottom plate 602. Circular rods 702 are inserted into the circular holes 701. Clamping plates 703 penetrate through both ends of the circular rods 702. Abutting nuts 704 are threadedly connected to the ends of the circular rods 702. Adjusting holes 705 are provided on the clamping plates 703.

[0026] Specifically: By welding and fixing both ends of the roller body 1 with the circular plate 2, not only the overall strength of the roller body 1 is enhanced, but also the roller body 1 is not prone to axial or radial displacement during handling. The design of the left clamping plate 4 and the right clamping plate 5, in cooperation with the bottom clamping mechanism 6 at the bottom and the top clamping mechanism 7 at the top, realizes multi-point clamping of the roller body 1, ensuring that the roller body 1 is firmly fixed during handling, reducing the risk of damage caused by shaking or slipping. At the same time, the bottom clamping mechanism 6 and the top clamping mechanism 7 can be finely adjusted according to the actual size and shape of the roller body 1, improving the clamping accuracy and adaptability.

[0027] The working principle here is as follows: The roller body 1 is cylindrical and is the main object to be clamped. The circular plate 2 is welded to both ends of the roller body 1, providing a basis for connection and fixation. First, place the roller body 1 between the left bottom plate 601 and the right bottom plate 602, and adjust the limit nut 604 on the screw 603 to ensure that the bottom clamping mechanism 6 firmly clamps the bottom of the roller body 1. Then, insert the round rod 702 into the round hole 701, and adjust the clamping force of the top clamping mechanism 7 through the clamping plate 703 and the abutting nut 704. When both the limit nut 604 and the abutting nut 704 are properly tightened, the bottom clamping mechanism 6 and the top clamping mechanism 7 work together to firmly clamp the roller body 1 from the upper and lower directions. This clamping method not only prevents the roller body 1 from moving in the horizontal direction but also prevents its movement in the vertical direction, ensuring the stability of the roller body 1 in subsequent operations. By adjusting the positions of the limit nut 604 and the abutting nut 704, and the adjustment hole 705, this clamping device can adapt to roller bodies 1 with different diameters and lengths, having high adaptability and flexibility.

[0028] As Figure 1 、 Figure 2 shown, in some embodiments, the connecting mechanism 3 includes a connecting block 301 fixedly installed on the circular plate 2, and a connecting roller 302 is welded on the connecting block 301. The working principle here is as follows: The connecting roller 302 is welded to the connecting block 301 and becomes a key component for connecting the connecting mechanism 3 with other devices or structures. The installation of the connecting block 301 should ensure firmness and reliability, avoiding loosening or falling off during use. The welding quality of the connecting roller 302 should meet relevant standards and requirements to ensure the connection strength and sealing performance.

[0029] As Figure 1 、 Figure 2 shown, in some embodiments, clamping grooves 8 are provided on the left clamping plate 4 and the right clamping plate 5, and the clamping grooves 8 can clamp the roller body 1.

[0030] Embodiment 2:

[0031] The solution in Embodiment 1 will be further introduced below in combination with the specific working method, as described in detail below:

[0032] As Figure 1 , Figure 2 , Figure 3 shown, in some embodiments, fixing blocks 9 are fixed on the left clamping plate 4 and the right clamping plate 5, and hanging holes 10 are symmetrically arranged on the fixing blocks 9. The working principle here is that the hanging holes 10 are specifically designed to connect hoisting equipment (such as cranes, hoists, etc.). By threading a lifting rope or chain through these hanging holes 10, the entire roller 1 clamping device and the roller 1 it clamps can be lifted and moved or transported. The hanging holes 10 are symmetrically arranged on the fixing blocks 9, which can ensure the balance during the hoisting process. When the lifting rope or chain is connected through the hanging holes 10 and a pulling force is applied, due to the symmetry of the hanging holes 10, the pulling force will be evenly distributed on the left clamping plate 4 and the right clamping plate 5, thus avoiding skew or distortion during the hoisting process.

[0033] Working step one: The bottom clamping mechanism 6 and the top clamping mechanism 7 apply clamping forces from the bottom and top directions of the roller 1 by adjusting their respective clamping components (such as the screw 603, the limiting nut 604, the round rod 702, the abutting nut 704, etc.), ensuring that the roller 1 is firmly clamped between the left clamping plate 4 and the right clamping plate 5. This multi-point clamping design improves the clamping accuracy and stability, reducing the shaking and slipping of the roller 1 during processing, transportation, or storage. When it is necessary to move or transport the entire roller 1 clamping device and the roller 1 it clamps, the symmetrically arranged hanging holes 10 on the fixing blocks 9 can be utilized. By threading a lifting rope or chain through these hanging holes 10 and connecting it to hoisting equipment (such as cranes, hoists, etc.), the hoisting of the entire device can be achieved. The symmetric arrangement of the hanging holes 10 ensures the balance during the hoisting process and avoids the occurrence of skew or distortion.

[0034] Working step two: The connecting mechanism 3 (such as the connecting block 301 and the connecting roller 302) is responsible for connecting the roller 1 clamping device to other equipment or structures. Through the connecting roller 302, power, torque, or other forms of energy can be transmitted to achieve the rotation, movement, etc. of the roller 1. At the same time, the connecting mechanism 3 also plays a role in supporting and fixing, ensuring the firm connection between the roller 1 clamping device and other components. During the entire working process, each part such as the clamping mechanism and the connecting mechanism 3 works together to jointly ensure the firm clamping, safe hoisting, and effective connection of the roller 1. This collaborative effect improves the working efficiency, safety, and reliability of the entire roller 1 clamping device.

[0035] The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
