According to the search results, the fin tube machine can roll and compound aluminum tubes of different specifications lined with copper tubes or steel tubes (also known as base tubes) through the cutter in the unit, and extrude fins at one time to achieve the effect of increasing the heat exchange area.

[0003] When a fin tube rolling machine in the prior art processes a steel tube, one end of the steel tube cannot be fixed for guidance, which causes the steel tube to shake significantly during processing and easily results in fin processing deviation. To address the above problem, an adjustable fin positioning device for a tube rolling machine is provided. Utility Model Content

The setting of the anti-skid layer makes the clamping blocks clamp the steel pipe more stably. The steel pipe fins will rotate and move during processing. During the rotational movement, since one end of the steel pipe is fixed inside the auxiliary component, the setting of the bearing can allow the steel pipe to drive the mounting block to rotate inside the fixed plate, thereby driving the fixed plate to slide on the slider guide rail, so that the entire auxiliary component drives one end of the steel pipe to move along the guide rail, thereby achieving the effect of auxiliary guiding the steel pipe. When the auxiliary component is driven to move to one end of the guide rail, the two groups of first push rod machines are started to drive the clamping blocks to loosen to complete the processing of a group of steel pipe fins, thereby avoiding the problem of large vibration frequency of the steel pipe affecting the processing accuracy during the processing of the steel pipe fins.

[0016] (2) The utility model starts the second push rod machine to drive the load-bearing plate to move, and the movement of the load-bearing plate drives the second telescopic rod to extend and retract at the same time, thereby increasing the stability of the movement of the load-bearing plate. The movement of the load-bearing plate can adjust the contact position between the fin extrusion wheel and the steel pipe to adapt to the processing of steel pipes of different sizes. The fin extrusion wheel rotates under the drive of the motor to perform fin forming processing on the clamped steel pipe.

[0030] By starting the second push rod machine 5 to drive the carrying plate 6 to move, the carrying plate 6 moves and drives the second telescopic rod 7 to extend and retract, so that the stability of the movement of the carrying plate 6 is increased. The movement of the carrying plate 6 can adjust the contact position between the fin extrusion wheel 9 and the steel pipe to adapt to the processing of steel pipes of different sizes. The fin extrusion wheel 9 rotates under the drive of the motor 10 to perform fin forming processing on the clamped and fixed steel pipe;

[0031] The steel pipe with the sleeve connected is passed through the two groups of clamping blocks 307 and placed between the three groups of fin extrusion wheels 9, and then the two groups of first push rod machines 305 are started to mobilize the two groups of clamping blocks 307 to move.

When the extrusion wheel 9 rotates to perform fin processing on the steel pipe, the processed part of the steel pipe will be driven by the fin extrusion wheel 9 for transportation, thereby driving the entire steel pipe for transportation. During the rotation and movement of the steel pipe, since one end of the steel pipe is fixed inside the auxiliary component 3, the setting of the bearing 303 can allow the steel pipe to drive the mounting block 304 to rotate inside the fixed plate 301, thereby driving the fixed plate 301 to slide the slider 302 on the guide rail 2, so that the entire auxiliary component 3 drives one end of the steel pipe to move along the guide rail 2, thereby achieving the effect of auxiliary guiding the steel pipe. When the auxiliary component 3 is driven to move to one end of the guide rail 2, the two groups of first push rod machines 305 are started to drive the clamping block 307 to loosen to complete the processing of a group of steel pipe fins, thereby avoiding the problem of large vibration frequency of the steel pipe affecting the processing accuracy during the processing of the steel pipe fins;

[0034] A water guide box 14 is fixedly mounted on the lower surface of the workbench 1, and the water guide box 14 is connected to the two groups of through holes 103;

[0035] A water collecting box 15 is provided on the upper surface of the placement plate 102, and the water collecting box 15 is provided just below the output end of the water guide box 14;

[0036] A drain pipe 16 is provided on one side of the water collecting tank 15 , and a valve 17 is provided on the outer surface of the drain pipe 16 .

[0037] When in use, firstly, the steel pipe with the sleeve connected to it is passed through the two groups of clamping blocks 307 and placed between the three groups of fin extrusion wheels 9, and then the two groups of first push rod machines 305 are started to mobilize the two groups of clamping blocks 307 to move, and the clamping blocks 307 can move to clamp and fix the steel pipe to be processed, and the first telescopic rod 306 is set to make the clamping blocks 307 move more smoothly, and the anti-slip layer 308 is set to make the clamping blocks 307 clamp the steel pipe more stably, and then the second push rod machine 5 is started to drive the bearing plate 6 to move, and the bearing plate 6 is fixed to the bearing plate 6. The movement of the carrier plate 6 drives the second telescopic rod 7 to extend and retract, which can increase the stability of the movement of the carrier plate 6. The movement of the carrier plate 6 can adjust the contact position between the fin extrusion wheel 9 and the steel pipe to adapt to the processing of steel pipes of different sizes. The fin extrusion wheel 9 rotates under the drive of the motor 10 to perform fin forming processing on the clamped steel pipe. When the fin extrusion wheel 9 rotates to perform fin processing on the steel pipe, the processed part of the steel pipe will be driven by the fin extrusion wheel 9 for transportation, thereby driving the entire steel pipe to be transported. The steel pipe rotates and moves During the movement, since one end of the steel pipe is fixed inside the auxiliary component 3, the setting of the bearing 303 allows the steel pipe to drive the mounting block 304 to rotate inside the fixed plate 301, thereby driving the fixed plate 301 to slide the slider 302 on the guide rail 2, so that the entire auxiliary component 3 drives one end of the steel pipe to move along the guide rail 2, thereby achieving the effect of auxiliary guidance of the steel pipe. When the auxiliary component 3 is driven to move to one end of the guide rail 2, the two groups of first push rod machines 305 are started to drive the clamping block 307 to loosen to complete a group of steel pipe fin processing, avoiding the problem of large steel pipe jitter frequency affecting processing accuracy during steel pipe fin processing. During processing, the water outlet pipe 12 sprays coolant to the processing area through the through groove 401 to cool and lubricate the steel pipe and fin extrusion wheel 9 during processing to improve processing quality and equipment life. The processed coolant flows into the water guide box 14 through the through hole 103, and then flows into the water collecting tank 15. After the water collecting tank 15 is full, the valve 17 is opened to discharge the cooling water from the drain pipe 16.
