Description

TECHNICAL FIELD

[0001] The utility model belongs to metal processing technical field, concretely relates to a cooling device for RTO type twist guide. BACKGROUND

[0002] In the steel rolling production process, guide tooling is one of the key equipment, and the guide tooling is installed before and after the roll pass to help the rolled piece to enter and guide the roll pass accurately and stably in the established direction and state during the profile steel rolling process. Its normal operation is directly related to the orderly development of production and the stability of product quality. Especially in the bar and wire rod rolling process, the use of twist guide is particularly important, and its function is to guide the rolled piece and perform twist operation on it to meet the specific rolling requirements. However, in actual production, the cooling system of the RTO type twist guide has obvious problems, which leads to frequent equipment damage and seriously restricts the production efficiency and product quality. Specifically, the water eye of the original guide water pipe is designed to be too small, which is easy to be blocked by impurities or scale, resulting in that the cooling water cannot flow normally. In this case, the cooling effect of the guide roller of the guide is seriously insufficient, which easily causes the guide roller to be locked and cracked, seriously affects the production efficiency and product quality, and also has certain safety hazards.

[0003] The patent CN204448844U twist guide device changes the internal structure of the twist guide, sets the water injection hole structure for injecting water into the first guide channel on the first guide channel, and cools the inner wall of the first guide channel in time. However, this setting of improving the internal structure of the twist guide is easy to be blocked after being used for a period of time due to the dirty site of the steel rolling production. CONTENT OF THE UTILITY MODEL

[0004] The technical problem to be solved by the utility model is to provide a cooling device for RTO type twist guide, which can cool the guide roller.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme:

[0006] A cooling device for RTO type twist guide, comprising a concave-shaped pipe frame matched with the width of the guide roller frame and a water pipe joint in communication with the pipe frame, and water outlets are arranged on the two side pipes of the pipe frame.

[0007] The further improvement of the utility model technical scheme is that the pipe frame comprises a horizontal pipe and side pipes arranged at the two ends of the horizontal pipe, and the side pipes and the horizontal pipe are in communication.

[0008] The further improvement of the utility model technical scheme is that the water pipe joint is arranged in the middle of the horizontal pipe, and the water pipe joint is arranged at an obtuse angle with the plane formed by the concave-shaped pipe frame.

[0009] The further improvement of the technical scheme of the utility model lies in that the bottom end of the side pipe is closed, and a plurality of water outlets are arranged on the two side pipes and the opening direction of the water outlet on each side pipe forms an angle of 0-30° with the plane perpendicular to the concave-shaped pipe frame.

[0010] The further improvement of the technical scheme of the utility model lies in that the water pipe joint is an eccentric handle type quick joint.

[0011] Thanks to the above technical scheme, the technical progress achieved by the utility model is that:

[0012] The cooling device is matched with the shape of the twist guide, is convenient to use, and a quick joint is designed on the device, so that the problem of too small water hole of the original water pipe of the twist guide is avoided, and the possibility of blockage is reduced; on the other hand, the water outlet arranged on the side pipe of the cooling device can make the cooling water more accurately act on the guide roller, effectively reducing the risk of guide roller seizure and cracking. This improvement not only improves the operation stability of the equipment, but also prolongs the service life of the guide, provides a powerful guarantee for efficient production of rolled steel rods and wires. The structure of the device is simple, easy to install and maintain, and is suitable for high-temperature and high-pressure environment of a rolled steel workshop. BRIEF DESCRIPTION OF DRAWINGS

[0017] The utility model will be further described in detail in combination with examples:

[0018] A cooling device for RTO type twist guide, comprising a concave-shaped pipe frame matched with the width of the guide roller frame and a water pipe joint 1 communicated with the pipe frame, and a water outlet 2 arranged on the two side pipes of the pipe frame. The pipe frame comprises a horizontal pipe 4 and side pipes 3 arranged at both ends of the horizontal pipe respectively, and the side pipes 3 and the horizontal pipe 4 are communicated. As shown in Figure 1 、 2 The connection of the horizontal pipe 4 and the two side pipes 3 can have two forms, one is that the end of the horizontal pipe 4 is directly connected with the side pipe 3, and the other is that the end of the horizontal pipe 4 is blocked, and the side pipe 3 is connected below the horizontal pipe 4, the side pipe 3 and the horizontal pipe 4 are internally communicated, and the water flow is facilitated.

[0019] Water pipe joint 1 is arranged in the middle of horizontal pipe 4, and water pipe joint 1 is arranged at an obtuse angle with the plane formed by the concave-shaped pipe frame. Since the cooling device of the application is placed on the guide roller frame of the twisting guide, the obtuse angle arrangement is more convenient for connecting the water pipe to the water pipe joint 1. In a preferred embodiment, the water pipe joint 1 is an eccentric handle type quick connector, which can quickly connect the water pipe and realize the rapid access of the external water source. This design not only improves the water passing capacity of the water pipe, but also avoids the problems of water leakage or inconvenient connection caused by unreasonable design of the water pipe joint.

[0020] The bottom end of the side pipe 3 is closed, and a plurality of water outlets 2 are arranged on the two side pipes 3, and the opening direction of the water outlet 2 on each side pipe 3 forms an angle of 0-30° with the plane perpendicular to the concave-shaped pipe frame. That is, the cooling water sprayed from the water outlet 2 on the side pipe 3 is aligned with the direction of the guide roller, which can directly cool it. The cooling water can directly impact the guide roller, forming a high-efficiency cooling effect. This design not only improves the coverage range of the cooling water, but also ensures that the cooling water can uniformly act on the surface of the guide roller, avoiding the situation of local overheating or insufficient cooling.

[0021] One embodiment of the application uses DN20 steel pipe as the water pipe material of the concave-shaped pipe frame. Compared with the smaller pipe diameter of the original water pipe, the diameter of the DN20 steel pipe is larger, effectively reducing the limitation of water flow and reducing the probability of water pipe blockage. The concave-shaped pipe frame is designed according to the structural characteristics of the twisting guide, forming a shape that matches the guide. This design not only ensures good adaptability of the water pipe device, but also provides more reasonable space for subsequent cooling water distribution.

[0022] Method for use:

[0023] Place the cooling device of the application on the guide roller frame of the twisting guide, align the water outlets on the two side pipes 3 with the direction of the guide roller, connect the water pipe of the external water source with the water pipe joint 1, open the water source, and the cooling water will be sprayed from the water outlet to directly cool the guide roller. When not in use, the cooling device of the application can be removed.
