[0054] For the steel material combined processing equipment of the above embodiment, the present invention provides a processing method of the steel material combined processing equipment, such as Fig.13 As shown, the following steps are included:

[0055] Step S1, firstly, the fin tube 1000 is screwed into the protective tube 102, and then the fin tube 1000 is clamped by the clamping mechanism, and then the first cutting motor 108 is started, and the first linear drive mechanism drives the first cutting knife of the first cutting motor 108 to move down into the cutting groove 104, and then the second linear drive mechanism drives the first cutting motor 108 to move horizontally to cut the spiral fins of the fin tube 1000, and the cutting grooves 1001 distributed in a plane are processed on the spiral fins of the fin tube 1000;

[0056] Step S2, the first linear drive mechanism drives the first cutter of the first cutting motor 108 to move upward and away from the cutting groove 104, and then the clamping motor 202 drives the clamping plate 109 to rotate by a set angle, and while the clamping plate 109 rotates, the third linear drive mechanism drives the clamping seat 201 to move toward the protective tube 102;

[0057] Step S3, the first linear drive mechanism drives the first cutting motor 108 to move the first cutter downward into the cutting groove 104, and then the second linear drive mechanism drives the first cutting motor 108 to move horizontally to cut the spiral fins of the fin tube 1000, and processes the cutting grooves 1001 distributed in another plane on the spiral fins of the fin tube 1000;

[0058] Step S4, repeating step S2 and step S3 until all the grooves 1001 on the spiral fins of the fin tube 1000 are processed.

[0059] After the processing is completed, the clamping disk 109 is released, and then the fin tube 1000 is rotated to separate the fin tube 1000 from the protection tube 102.

[0060] In the above embodiment, since the fin tube 1000 needs to move one pitch to the left for one rotation, the clamping plate 109 also needs to move one pitch to the left for one rotation. If the rotation angle of the clamping plate 109 is α, the distance the clamping plate 109 needs to move to the left is α / 360°*pitch.

[0061] Embodiment 3

[0062] In both the first and second embodiments, the fin tube 1000 needs to be screwed into the protective tube 102, which can be done manually. In order to improve the automation of the processing, the fin tube 1000 is automatically screwed into the protective tube 102. This embodiment provides a steel combination processing device, such as Figure 10-12 As shown, different from the second embodiment, a second cutter 301 is provided on the left side of the clamping plate 109, the second cutter 301 is connected to the second slide 303 through a bearing, and the second cutter 301 is connected to the output end of the second cutting motor 302, the second slide 303 is connected to the second column 304 through a slide rail, and the second column 304 is provided with a fourth linear drive mechanism for driving the second slide 303 to move longitudinally;

[0063] A semicircular material trough is provided on the clamping seat 201 on the right side of the clamping disk 109, and a pushing block 305 is provided in the material trough and is coaxially arranged with the material trough. The pushing block 305 is connected to the output shaft of the pushing motor 306, and the pushing motor 306 is connected to the fifth linear drive mechanism 307. The fifth linear drive mechanism 307 is used to drive the pushing motor 306 and the pushing block 305 to move horizontally to the left.

[0064] In the embodiment of the present invention, the fourth linear drive mechanism includes a fourth ball screw pair, both ends of the screw of the fourth ball screw pair are connected to the second column 304 through bearings, the nut of the fourth ball screw pair is connected to the second slide 303, and one end of the screw of the fourth ball screw pair is connected to the fourth linear drive motor through a bearing. The fourth linear drive motor outputs torque and drives the second slide 303 to move longitudinally through the fourth ball screw pair.

[0065] In an embodiment of the present invention, the left end of the pusher block 305 is tapered, and the diameter of the left end of the pusher block 305 is smaller than the inner diameter of the fin tube 1000. The tapered pusher block 305 can be inserted into the fin tube 1000. In order to increase the friction between the pusher block 305 and the fin tube 1000, a plurality of plugs slidably connected to the pusher block 305 are arranged on the outer periphery of the pusher block 305, and a jack matching with the plug is arranged on the pusher block 305, and the jack is arranged along the radial direction of the pusher block 305. A first spring is arranged in the jack, and the first spring connects the pusher block 305 and the plug. After the plug is inserted into the fin tube 1000, the pressure between the plug and the fin tube 1000 can be provided by the first spring.

[0066] In the embodiment of the present invention, the fifth linear drive mechanism 307 is a cylinder or a hydraulic cylinder.

[0067] In the embodiment of the present invention, a distance sensor 308 is provided on the second slide seat 303 below the second cutter 301 .

[0068] Different from the second embodiment, the transmission mechanism and the clamping motor 202 are arranged inside the clamping seat 201, a cylinder is connected to the right end of the clamping disk 109, and the driven gear ring 204 of the transmission mechanism is arranged on the cylinder.

[0069] For the steel material combined processing equipment of the above embodiment, the process of screwing the fin tube 1000 into the protective tube 102 is as follows:

[0070] First, the fin tube 1000 is placed in the material trough, and then the fourth linear drive mechanism drives the second slide 303 to move downward, so that the distance sensor 308 of the second slide 303 moves to the height of the spiral fins of the fin tube 1000;

[0071] The fifth linear drive mechanism 307 pushes the fin tube 1000 to move leftward, so that the left end of the fin tube 1000 extends out of the clamping plate 109, until the distance sensor 308 detects that the distance between the spiral fin and the distance sensor 308 reaches a predetermined value;

[0072] Then the second cutting motor 302 drives the second cutter 301 to rotate, and the fourth linear drive mechanism drives the second cutter 301 to move downward to cut the left end of the fin tube 1000; then the fourth linear drive mechanism drives the second cutter 301 to reset;

[0073] Since the fin tube 1000 has a processing allowance, the purpose of cutting the left end of the fin tube 1000 is to remove the processing allowance at the left end of the fin tube 1000;

[0074] Then the fifth linear drive mechanism 307 pushes the fin tube 1000 to the left for a predetermined distance, so that the left end of the fin tube 1000 is inserted into the protective tube 102, and the spiral fins of the fin tube 1000 contact the spiral grooves 103 of the protective tube 102; since the horizontal distance between the distance sensor 308 and the protective tube 102 is determined, after the distance between the spiral fins and the distance sensor 308 reaches a predetermined value, the distance between the spiral fins and the protective tube 102 is also determined. At this time, the fifth linear drive mechanism 307 pushes the fin tube 1000 to the left for a predetermined distance, so that the spiral fins of the fin tube 1000 can contact the spiral grooves 103 of the protective tube 102.

[0075] Then, while the push motor 306 rotates, the fifth linear drive mechanism 307 pushes the fin tube 1000 to the left, so that the fin tube 1000 is screwed into the protective tube 102, and then the fifth linear drive mechanism 307 drives the push block 305 to reset.

[0076] The processed fin tube 1000 can be taken out by reversing the push motor 306 and cooperating with the fifth linear drive mechanism 307 to move rightward.

[0077] Furthermore, a buffer mechanism is provided between the push motor 306 and the fifth linear drive mechanism 307. The buffer mechanism includes two buffer seats respectively connected to the push motor 306 and the fifth linear drive mechanism 307. A telescopic rod is provided between the buffer seats, and a second spring is provided on the telescopic rod. Since the spiral fins of the fin tube 1000 may not be screwed into the spiral groove 103 of the protective tube 102 when they contact, the fin tube 1000 needs to be rotated a certain angle before the spiral fins can be screwed into the spiral groove 103 of the protective tube 102. At this time, the fifth linear drive mechanism 307 pushes the fin tube 1000 to move, which may cause excessive pressure between the spiral fins and the protective tube 102 and cause deformation. By providing a buffer mechanism for buffering, even if the spiral fins cannot be screwed into the spiral groove 103 immediately when the contact begins, the buffer mechanism can also be used to avoid excessive pressure between the spiral fins and the protective tube 102.

[0078] The embodiment of the present embodiment is described above in conjunction with the accompanying drawings, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present embodiment, ordinary technicians in this field can also make many forms without departing from the purpose of the present embodiment and the scope of protection of the claims, all of which are within the protection of the present embodiment.
