Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and more specifically, to a high-efficiency cooling mechanism for cladding the inner wall of a pipe. Background Technology

[0002] Cladding equipment refers to devices used for cladding processes on the surface of parts, mainly including laser cladding equipment, plasma cladding equipment, and arc cladding equipment. In many industrial applications, materials are transported inside pipes, such as transporting ore particles in the mining industry or coal powder in the power industry. The flow of these materials constantly erodes the inner wall of the pipe, causing wear. By cladding the inner wall, a cladding layer with excellent wear resistance can be formed. After cladding with wear-resistant materials such as nickel-based alloys, it can effectively resist the erosion of materials and greatly extend the service life of the pipe.

[0003] During the cladding process on the inner wall of pipes, rapid cooling of the high-temperature molten pool is crucial for obtaining a good cladding layer quality and reducing deformation in the heat-affected zone. Traditional cooling methods often suffer from uneven cooling and low efficiency, leading to unstable cladding layer quality and even affecting the overall performance of the pipe. Therefore, we propose a highly efficient cooling mechanism for cladding the inner wall of pipes. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a high-efficiency cooling mechanism for pipe inner wall cladding, so as to solve the technical problems of uneven cooling, low efficiency and poor pipe forming quality of the current cladding device.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a high-efficiency cooling mechanism for cladding the inner wall of a pipe, comprising a drive frame and a limiting mechanism. The front end of the drive frame is provided with a cladding head, and side plates are installed on both sides of the upper end face of the drive frame. A side groove is opened on the upper side of the side plate, and an adjustment groove is opened inside the side groove. The limiting mechanism is installed between the side grooves of the two side plates, and the limiting mechanism is composed of a first clamping plate and a second clamping plate.

[0006] The utility model discloses a cooling device for laser cladding head, including drive frame, the side plate of drive frame, the cladding head of drive frame, the bottom connecting pipe of drive frame, the support pipe of drive frame and the top connecting pipe of drive frame, the bottom connecting pipe, the support pipe and the top connecting pipe of drive frame are connected with the cladding head, and the bottom connecting pipe, the support pipe and the top connecting pipe are connected with the side plate of drive frame.

[0007] Preferably, the rear end of the drive frame is provided with a material pipe on both sides, the upper side of the rear end of the drive frame and the inner side of the side plate are provided with a flow cavity, and a cover plate is installed at the opening of the flow cavity.

[0008] Preferably, the outer side of the cover plate and the cladding head are provided with a pipe joint, the pipe joints of the drive frame and the cladding head are connected by the bottom connecting pipe, the side plate is designed in a U shape, and the two ends of the side plate are provided with a pipe joint, and the two pipe joints of the side plate are connected with the pipe joint of the cladding head by the support pipe and the top connecting pipe.

[0009] Preferably, the front end of the support pipe passes through the lower side of the top connecting pipe to complete the support, and the inner end of the material pipe is connected with the flow cavity of the side plate.

[0010] Preferably, the two ends of the first clamping plate are provided with a side sliding block, and a side box is slidingly connected on the side sliding block, the side box is slidingly installed in the corresponding adjusting groove, a spring is arranged in the side box, and the outer end of the spring is fixed on the side sliding block.

[0011] Preferably, the two ends of the second clamping plate are rotatably installed in the side groove by a rotating shaft, the connecting end of the first clamping plate and the second clamping plate is provided with a convex surface and a concave surface, and the convex surface and the concave surface are mutually butted.

[0012] Preferably, the connecting part of the first clamping plate and the second clamping plate is provided with a clamping opening, and the clamping opening clamps the middle part of the support pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model designs a flow cavity, through which coolant is introduced into the flow cavity of one side plate via a material pipe. Then, through the bottom pipe, support pipe, and top pipe, the coolant circulates within the corresponding flow cavity and the internal cavity of the cladding head. The built-in flowing coolant rapidly dissipates the high-temperature heat of the device, and then discharges it outward through the material pipe of the other side plate to complete the circulation. The cover plate is snapped on to seal the flow cavity, facilitating subsequent disassembly and cleaning. The bottom pipe, support pipe, and top pipe work together to achieve the flow of coolant between the drive frame and the cladding head, allowing the heat in the working area to be rapidly reduced through heat exchange, ensuring processing efficiency and quality.

[0015] 2. This utility model also incorporates a limiting mechanism. The distribution of the support tube and top pipe is complex, and existing devices lack effective pipe limiting. The messy pipework makes it easy for the pipe to come into contact with the inner wall of the pipe when the device is inserted, leading to damage. During assembly, the support tube is passed between the first and second clamping plates, aligning the support tube with the clamping opening. Then, the first clamping plate is pushed backward, compressing the spring and increasing the distance between the first and second clamping plates. The second clamping plate is then rotated to close, aligning the convex and concave surfaces of the first and second clamping plates. At this point, the support tube is clamped and positioned within the limiting mechanism. The outward extension of the support tube passes through the lower side of the top pipe, supporting and limiting the top pipe. This limiting mechanism tidies up the pipe distribution, ensuring pipe safety during processing. Attached Figure Description
