Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline thermal insulation, and in particular relates to a pipeline tee thermal insulation layer wire cutting processing device and a use method thereof. Background Art

[0002] There are two main processing methods for the existing polyurethane insulation structure at the tee of the pipeline. Method 1: The two components of polyurethane A and B are mixed in a specific proportion and directly injected into a mold pre-installed on the outside of the tee pipe fitting or a special mold shell. The mixed raw materials undergo a chemical reaction in the mold, foaming, expanding and solidifying to form an insulation layer that fits tightly to the tee pipe fitting; Method 2: The tee polyurethane insulation structure is prepared by using a segmented prefabrication and precision assembly process. First, the polyurethane insulation layer of the straight pipe section is prefabricated, and then the insulation layer of the straight pipe section is cut, and finally assembled using a bevel splicing process.

[0003] Disadvantages and reasons of the above two processing methods of polyurethane insulation structure of three-way pipe: 1. Method 1: The existing polyurethane insulation structure foaming process has extremely stringent requirements for the construction environment. It must be carried out in a clean, dust-free, dry and ventilated environment with a temperature maintained at 15-35°C. However, in actual projects, the pipeline laying scenarios are complex and changeable. Whether it is the natural conditions such as wind, sand, rain and snow faced by outdoor municipal pipeline construction, or the humid and dusty working environment inside industrial plants, it is difficult to meet the conditions required by the foaming process, which can easily lead to quality defects such as pores, cracks, and uneven density in the polyurethane foam. In addition, for tee structures with different pipe diameters, angles and connection forms, the traditional prefabrication processing method requires the separate design and manufacture of special molds, which is expensive to customize. At the same time, non-standard molds have poor versatility and low reuse rate, resulting in resource waste, significantly increasing the production cost of pipe tee insulation structures, and seriously restricting the economic efficiency and construction efficiency of pipe insulation construction projects. 2. Method 2: When prefabricating the polyurethane insulation layer of the pipe tee elbow, if the cutting accuracy is not well controlled, the cutting surface will be uneven or the angle will be inaccurate, which may cause the gap at the joint of the polyurethane insulation layer of the pipe tee to be too large or too small, making it difficult to achieve seamless docking, affecting the overall performance of the pipe tee insulation structure; To this end, we propose a pipeline tee insulation layer wire cutting processing device and its use method.

[0014] A method for using a pipeline tee insulation layer wire cutting processing device includes the following steps: A. Positioning and clamping: Place the polyurethane insulation pipe shell on the loading platform, start the clamping servo motor, drive the clamping screw shaft to rotate, and connect the clamping screw shaft to the two slider connecting rods through the built-in reverse threaded bearings, so that the two slider connecting rods move inward synchronously, thereby driving the positioning sliders at both ends of the two slider connecting rods to move in the positioning slide grooves toward the two sides of the polyurethane insulation pipe shell, thereby clamping and fixing the polyurethane insulation pipe shell, and the clamping servo motor stops working; B. Adjust cutting position: According to the requirements of the cutting position of the polyurethane insulation pipe shell, the position of the frame moving mechanism is adjusted. At this time, the moving servo motor starts, drives the moving screw shaft to rotate, and causes the threaded seat to move on the fixed base plate through the thread transmission with the moving screw shaft, thereby driving the moving frame to move on the guide rail through the moving slider, so that the moving frame drives the wire cutting mechanism to move to the cutting position of the polyurethane insulation pipe shell, and the moving servo motor stops working; C.

At this time, the spring pressure plate moves in the sealing frame, causing the pressure in the sealing frame to change. At this time, the pressure gauge detects that the pressure in the sealing frame increases or decreases. The operator adjusts the state of the cutting line according to the pressure value detected by the pressure gauge, and according to the size requirements of the polyurethane insulation pipe shell to be cut, the cutting line is moved in the upper slide and the lower slide respectively through the upper slide and the lower slide, so that the cutting line is close to the outside of the polyurethane insulation pipe shell and maintains a natural tight state to meet the wire cutting process requirements; D.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with a wire cutting mechanism. When in use, the cutting servo motor drives the spur gear and the gear shaft to engage and transmit, driving the upper cutting table to rotate in the upper frame, and driving the cutting wire to rotate, so that the cutting wire drives the lower cutting table to rotate in the lower frame, thereby making the upper cutting table, cutting wire and lower cutting table perform circular motion synchronously, so that the cutting wire cuts a precise circular wire cutting on the polyurethane insulation pipe shell, so that the circular wire cutting of the polyurethane insulation pipe shell meets the size requirements of the pipe tee insulation layer. Compared with traditional manual cutting, the cross-section cut by the wire cutting mechanism of the present invention is more neat and has a higher fit, thereby improving the cutting accuracy of the pipe tee insulation layer and greatly improving the insulation effect of the polyurethane insulation pipe shell at the pipe tee. 2. The present invention is provided with a wire adjustment mechanism, which adjusts the working state of the cutting wire before the wire cutting process. When the cutting wire is tilted, tightened or relaxed, the force on the cutting wire will be transmitted to the spring pressure plate and the spring through the roller, causing the spring to be compressed or naturally extended. At this time, the spring pressure plate moves in the sealing frame, causing the pressure in the sealing frame to change. At this time, the pressure gauge detects that the pressure in the sealing frame increases or decreases. The operator adjusts the state of the cutting wire according to the pressure value detected by the pressure gauge, and moves the cutting wire in the upper slide groove and the lower slide groove respectively according to the size requirements of the polyurethane thermal insulation pipe shell to be cut, so that the cutting wire is close to the outside of the polyurethane thermal insulation pipe shell and maintains a natural tight state to meet the wire cutting process requirements. The cutting wire can be adjusted according to the real-time state of the cutting wire (loose, tight, deflected) to keep the cutting wire in a vertically tight state, thereby ensuring the accuracy of wire cutting and improving the adjustment and use efficiency of wire cutting. 3. The present invention is provided with a frame moving mechanism. When in use, the position of the frame moving mechanism is adjusted according to the cutting position requirement of the polyurethane thermal insulation pipe shell. The moving servo motor drives the moving screw shaft to rotate, so that the threaded seat moves on the fixed base plate through the thread transmission with the moving screw shaft, and then drives the moving frame to move on the guide rail through the moving slider, so that the moving frame drives the wire cutting mechanism to move to the cutting position of the polyurethane thermal insulation pipe shell. The frame moving mechanism can drive the wire cutting mechanism to adjust and move on the bearing base mechanism, so as to achieve the adjustment of any cutting position of the polyurethane thermal insulation pipe shell, facilitate the use of wire cutting position adjustment, and improve the convenience of use. 4. The present invention is provided with a bearing base mechanism and a positioning clamping mechanism. When in use, the clamping servo motor drives the clamping screw shaft to rotate, and the clamping screw shaft is connected to the two slider connecting rods through a built-in reverse threaded bearing, so that the two slider connecting rods move inward synchronously, thereby driving the positioning sliders at both ends of the two slider connecting rods to move toward both sides of the polyurethane insulation pipe shell in the positioning slide groove, thereby clamping and fixing the polyurethane insulation pipe shell, avoiding the problems of offset and inaccurate positioning of the polyurethane insulation pipe shell during online cutting processing, and enabling the polyurethane insulation pipe shell to be accurately positioned on the stage, thereby improving the stability, reliability and accuracy of the online cutting processing of the polyurethane insulation pipe shell.

When the cutting line 507 is tilted, tensioned or relaxed, the force on the cutting line 507 is transmitted to the spring pressure plate 604 and the spring 605 through the roller 603, causing the spring 605 to be compressed or naturally stretched. At this time, the spring pressure plate 604 moves in the sealing frame 606, causing the pressure in the sealing frame 606 to change.

Positioning and clamping: The polyurethane heat-insulating pipe shell (2) is placed on the loading platform (103), the clamping servo motor (304) is started, and the clamping screw shaft (303) is driven to rotate. The clamping screw shaft (303) is connected to the two slider connecting rods (302) through the built-in reverse threaded bearings, so that the two slider connecting rods (302) move inward synchronously, thereby driving the positioning sliders (301) at both ends of the two slider connecting rods (302) to move in the positioning chute (104) toward both sides of the polyurethane heat-insulating pipe shell (2), thereby clamping and fixing the polyurethane heat-insulating pipe shell (2), and the clamping servo motor (304) stops working; B.
