AI Technical Summary
Traditional straight seam welded pipe grinding equipment has low cooling efficiency, high water consumption, and the welded pipe is prone to sinking during the grinding process, resulting in poor weld grinding effect.
Water spray pipes are installed on both the front and rear sides of the grinding wheel to form a water curtain for cooling, and support rollers are installed under the grinding wheel to stabilize the welded pipe, thereby reducing water consumption and improving the stability of the welded pipe.
It achieves efficient cooling, saves water resources, and improves the stability and quality of welded pipe grinding.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of production equipment, and in particular to a precision straight seam welded pipe grinding and cooling device. Background Technology
[0002] During the production and processing of straight seam welded pipes, steel plates are usually joined and welded together using high-frequency heating. After welding, the weld seam of the straight seam welded pipe needs to be ground to make its surface smoother and burr-free. In traditional straight seam welded pipes, a water spray pipe is fixedly installed behind the grinding wheel for water cooling when the pipe is ground by a grinding wheel. This method can only cool the straight seam welded pipe once and requires a large amount of water, which is not conducive to saving production costs and water resources. In addition, when grinding straight seam welded pipes with traditional grinding devices, the pipes are prone to sinking downwards due to the downward pressure of the grinding wheel, resulting in poor grinding effect of the grinding wheel on the weld seam. Therefore, improvements are still needed. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a precision straight seam welded pipe grinding and cooling device, comprising a fixed frame and a grinding wheel. The fixed frame has a U-shaped groove, and the grinding wheel is disposed within the U-shaped groove. A motor is mounted at the rear end of the grinding wheel and is installed on the fixed frame. Water spray pipes are provided on both the front and rear sides of the fixed frame, and are located on the left and right sides of the U-shaped groove. Each water spray pipe has several spray nozzles. A water supply pipe is connected to the rear side of each water spray pipe, and a water pump is installed on the water supply pipe and mounted on the fixed frame. Two support wheels are located below the grinding wheel, positioned on the left and right side walls of the U-shaped groove of the fixed frame.
[0004] Preferably, a fixing block is provided on the rear side of the supporting wheel and is installed on the left and right side walls of the U-shaped through groove of the fixing frame through the fixing block.
[0005] Preferably, a viewing window is provided on one side of the fixing frame, and a hinge is provided between the viewing window and the fixing frame and the hinge is used for connection. A limit block is provided on the viewing window.
[0006] Preferably, the fixing frame is provided with a limit strip.
[0007] The beneficial effects of this utility model are: the structure of this utility model is reasonable and easy to use. By setting water curtains on the front and rear sides of the grinding wheel, the straight seam welded pipe can be cooled while reducing water consumption and saving water resources. In addition, the setting of the support wheel can support the straight seam welded pipe, thereby making the straight seam welded pipe more stable during grinding and improving the production quality of the straight seam welded pipe.

[0008] This utility model will be described by way of example and with reference to the accompanying drawings, wherein: Figure 1 This is a schematic diagram of the overall structure of this utility model; Figure 2 This is a side view structural diagram of the present invention; In the diagram: 1. Fixing frame; 2. Motor; 3. Water pump; 4. Grinding wheel; 5. Water pipe; 6. Spray nozzle; 7. Spray pipe; 8. Supporting wheel; 9. Fixing block; 10. Viewing window; 11. Hinge; 12. Limiting strip; 13. Limiting protrusion. Detailed Implementation
[0009] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.
[0010] Unless otherwise stated, any feature in this specification may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is merely one example of a series of equivalent or similar features.
[0011] like Figure 1 , 2 The precision straight seam welded pipe grinding and cooling device shown includes a fixed frame 1 and a grinding wheel 4. The fixed frame 1 has a U-shaped through groove, and the grinding wheel 4 is disposed in the U-shaped through groove. A motor 2 is disposed at the rear end of the grinding wheel 4 and is mounted on the fixed frame 1. Water spray pipes 7 are disposed on the front and rear sides of the fixed frame 1 and are disposed on the left and right sides of the U-shaped through groove. Several water spray nozzles 6 are disposed on the water spray pipes 7. A water supply pipe 5 is connected to the rear side of the water spray pipe 7 and a water supply pump 3 is installed on the water supply pipe 5 and is mounted on the fixed frame 1. Two support wheels 8 are disposed below the grinding wheel 4 and are disposed on the left and right side walls of the U-shaped through groove of the fixed frame 1.
[0012] The rear side of the supporting wheel 8 is provided with a fixing block 9, which is installed on the left and right side walls of the U-shaped through groove of the fixing frame 1.
[0013] A viewing window 10 is provided on one side of the fixing frame 1. A hinge 11 is provided between the viewing window 10 and the fixing frame 1 and the hinge 11 is used for connection. A limit block 13 is provided on the viewing window 10.
[0014] The fixing frame 1 is provided with a limit strip 12.
[0015] During use, the water pump 3 pressurizes the water in the water pipe 5 and delivers it to the water spray pipe 7, which is then sprayed out through the water spray nozzle 6 to form a water curtain. When the straight seam welded pipe passes through the grinding device, it will first pass through the water curtain in front of the fixed frame 1 for cooling when it enters the U-shaped through groove of the fixed frame 1. After that, the straight seam welded pipe will pass between the grinding wheel 4 and the support wheel 8. The support wheel 8 will support the straight seam welded pipe when the grinding wheel 4 grinds the straight seam welded pipe, thereby improving the grinding quality of the straight seam welded pipe.
[0016] The viewing window 10 is designed to facilitate observation of the grinding process of the straight seam welded pipe; the hinge 11 is designed to facilitate opening the viewing window 10 for maintenance or replacement of the grinding wheel 4; the limiting strip 12 and the limiting block 13 are designed to facilitate fixing the viewing window 10 when it is closed.
[0017] The beneficial effects of this utility model are: the structure of this utility model is reasonable and easy to use. By setting water curtains on the front and rear sides of the grinding wheel, the straight seam welded pipe can be cooled while reducing water consumption and saving water resources. In addition, the setting of the support wheel can support the straight seam welded pipe, thereby making the straight seam welded pipe more stable during grinding and improving the production quality of the straight seam welded pipe.
