Description

Technical Field

[0001] The present invention relates to the technical field of solar collector production devices, and particularly to a fin processing device and a fin processing method. Background Art

[0002] Currently, a special processing device for processing semi-circular heat-absorbing fins is disclosed. The special processing device for the semi-circular heat-absorbing fins of a solar collector is composed of a pressure roller arranged on a frame, and is used for processing a solar heat collecting sheet composed of a heat collecting tube and fins. The special processing device is composed of a pair of mutually cooperating pressure rollers. The upper pressure roller has a pressing groove with a semi-circular cross-section sunken inward, and the diameter of the pressing groove is equal to the sum of the outer diameter of the heat collecting tube and the fin thickness. The lower pressure roller has a supporting groove with a semi-circular cross-section sunken inward, and the diameter of the supporting groove is equal to the diameter of the heat collecting tube. The pair of pressure rollers rotate at an equal linear speed driven by a motor. This device can press into a semi-circular shape that closely fits the outside of the heat collecting tube, increasing the heat exchange area between the fins and the heat collecting tube. However, in this manufacturing process, plugs and pressure heads need to be installed at both ends of the heat collecting tube respectively, and the pressing position of the fins needs to be positioned, all of which require manual operation. Therefore, the production is very troublesome. Summary of the Invention

Below the fins and the heat collecting tube, there is an installation box. The front side, rear side, and left side of the installation box are all synchronously and slidably installed with limiting plates. The limiting plates on the front side and rear side of the installation box are both installed with fixing plates for supporting the fins. On the limiting plate on the left side of the installation box, a plug is fixedly installed coaxially with the heat collecting tube. On both sides of the plug, baffles for cooperating with the left side wall of the fin are fixedly installed. Horizontally and elastically connected to the top of the plug is a pressing plate for cooperating with the fin. On the right side of the fins and the heat collecting tube, there is an installation seat for the rotation of a first screw rod and a second screw rod. A first receiving plate and a second receiving plate that move horizontally left and right are respectively screwed on the first screw rod and the second screw rod. On the first receiving plate, a pressure head that cooperates coaxially with the heat collecting tube is fixedly installed. On the second receiving plate, a support frame is fixedly installed. At the opening of the support frame, clamping plates for cooperating with the right sides of the fins and the heat collecting tube are respectively slidably installed. Inside the support frame, a push plate controlled by a cylinder moves. At both ends of the push plate, sliding sleeves for controlling the clamping plate on the same side through a first transmission plate are respectively slidably installed. Each sliding sleeve is also connected to the corner of the adjacent support frame through a second transmission plate.

[0006] A further preferred embodiment of the present invention: V-shaped plates are fixedly installed on both sides of the lower pressing roller, and both ends of the opening of the V-shaped plate are fixedly installed with the first support groove and the second support groove respectively.

[0007] A further preferred embodiment of the present invention: The limiting plate on the left side of the installation box is located below the front limiting plate and the rear limiting plate of the installation box. A double-layer gear is also rotatably installed in the installation box. A transmission rack is installed on each limiting plate. The limiting plate on the left side of the installation box is meshed with the bottom of the double-layer gear through the transmission rack, and the front limiting plate and the rear limiting plate of the installation box are respectively meshed with both sides of the top of the double-layer gear through the transmission rack.

[0011] A processing method for fins of a fin processing device includes the following steps:

[0012] S1: Place the heat collecting tube in the first support groove of the V-shaped plate, place the fin on the heat collecting tube, and the fixing plate supports both ends of the fin. Start the motor controlling the first lead screw to rotate forward. The first lead screw drives the first receiving plate to move leftward. The pressing head on the first receiving plate is inserted into the heat collecting tube, and then the partition plate and the pressing head push the fin and the heat collecting tube to continue moving leftward;

[0013] S2: The left sides of the heat collecting tube and the fin respectively contact the plug and the baffle. The plug is inserted into the left end of the heat collecting tube, and the fin contacts the baffle; control the motor of the first lead screw to continue rotating forward, the first receiving plate continues to move leftward, the partition plate and the pressing head push the fin and the heat collecting tube to continue moving leftward, and the limiting plate on the left side of the installation box moves leftward. The limiting plate on the left side of the installation box drives the double-layer gear to rotate through the transmission rack;

[0014] S3: The front limiting plate and the rear limiting plate of the installation box will be driven by the double-layer gear to move towards the middle at the same time, so that the front limiting plate and the rear limiting plate of the installation box fix the front and rear sides of the fin, and the pressing plate fixes the left end of the fin through the ball. At this time, the motor of the first lead screw is turned off;

[0015] S4: Start the cooperating upper pressure roller and lower pressure roller, and move the upper pressure roller and the lower pressure roller to the left simultaneously. When the upper pressure roller and the lower pressure roller move to the middle of the heat collecting pipe and the fin, control the motor of the second lead screw to rotate forward. The second receiving plate drives the support frame to move leftward to the designated position, and the air cylinder pushes the push plate to start working. The sliding sleeves on the push plate move towards the middle simultaneously. Limited by the second transmission plate, the first transmission plate is controlled to drive the clamping plates to move towards the middle simultaneously to fix the right ends of the heat collecting pipe and the fin.

[0016] S5: The upper pressure roller and the lower pressure roller continue to move to the left simultaneously until they both move to the leftmost ends of the heat collecting pipe and the fin. Control the motor of the first lead screw to reverse. The first receiving plate drives the partition plate and the pressing head to move rightward, so that the partition plate and the pressing head are separated from the fin and the heat collecting pipe respectively. Then, control the motor of the second lead screw to reverse again, so that the first receiving plate and the second receiving plate move rightward at the same speed, separating the plug and the baffle from the fin and the heat collecting pipe. After moving to the designated position, control the air cylinder to drive the sliding sleeves on the push plate to move towards the upper and lower ends simultaneously, and the clamping plates are separated from the workpiece at the same time, and the work is completed.

[0017] The present invention has the following beneficial effects:

[0018] 1. By placing the heat collecting pipe in the first support groove of the V-shaped plate, the present invention can simply fix and position the heat collecting pipe. By controlling the movement of the heat collecting pipe and the fin, the installation box is controlled to work to fix the fin, solving the problem of manual positioning, improving the work efficiency, and reducing the labor intensity.

[0019] 2. The present invention drives the first lead screw to rotate through the motor, thereby controlling the pressing head to move into the heat collecting pipe. Then, by controlling the pressing head to drive the heat collecting pipe to move, the plug is installed in the heat collecting pipe, solving the problems of manual installation of the plug and the pressing head, improving the work efficiency, and reducing the labor intensity.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] As shown in Figures 1-6, a fin processing device includes a cooperating upper pressing roller 1 and a lower pressing roller 2. Between the upper pressing roller 1 and the lower pressing roller 2, fins 4 and a heat collecting tube 3 are arranged vertically. Below the fins 4 and the heat collecting tube 3, there is an installation box 5. On the front, rear, and left sides of the installation box 5, limiting plates 6 are synchronously and slidably installed in cooperation. Fixed plates for supporting the fins 4 are installed on the limiting plates 6 on the front and rear sides of the installation box 5. On the limiting plate 6 on the left side of the installation box 5, a plug 26 is coaxially and fixedly installed with the heat collecting tube 3. On both sides of the plug 26, baffles 27 for cooperating with the left side wall of the fin 4 are fixedly installed. Horizontally and elastically connected to the top of the plug 26 is a pressing plate for cooperating with the fin 4. Such a setting enables control and movement through the control board 11 on one side of the upper pressing roller 1 to separate the pressing plate from the fin 4. On the right side of the fin 4 and the heat collecting tube 3, there is an installation seat 12 for the rotation of the first lead screw 13 and the second lead screw 29. Threaded connections are respectively provided on the first lead screw 13 and the second lead screw 29 with a first receiving plate 23 and a second receiving plate 22 that move horizontally left and right. Through holes are respectively opened in the middle of the first receiving plate 23 and one end of the second receiving plate 22. The sizes of the through holes are larger than the diameters of the first lead screw 13 and the second lead screw 29.

The first receiving plate 23 and the second receiving plate 22 are respectively threadedly connected to the first lead screw 13 and the second lead screw 29 through the threaded holes. Sliding holes for slidably installing on the limiting rods are respectively opened at one end of the first receiving plate 23 and on the second receiving plate 22. The first receiving plate 23 can only be controlled by the first lead screw 13 controlled by the motor 28, and the second receiving plate 22 can only be controlled by the second lead screw 29 controlled by the motor 28. The motors 28 in the application are all self-locking motors that can rotate forward and backward. This is prior art and will not be elaborated further. A pressing head 25 coaxially cooperating with the heat collecting tube 3 is fixedly installed on the first receiving plate 23. A support frame 15 is fixedly installed on the second receiving plate 22. Clamping plates 18 for cooperating with the right sides of the fins 4 and the heat collecting tube 3 are respectively slidably installed at the openings of the support frame 15. Inside the support frame 15, a push plate 16 controlled by a cylinder 14 moves.

A double-layer gear 30 is also rotatably installed in the installation box 5. Such a setting can make the limiting plate 6 on the left side of the installation box 5, the front limiting plate 6 of the installation box 5, and the rear limiting plate 6 of the installation box 5 move synchronously when the double-layer gear 30 rotates. A transmission rack 31 is installed on each limiting plate 6.

[0034] Two partition plates 24 are fixedly installed on the first receiving plate 23. A pressing head 25 is fixedly installed between the tops of the two partition plates 24. One side of the partition plate 24 cooperates with the right side of the fin 4. Such a setting can position the fin 4 and determine the position where the fin 4 is pressed.

[0035] A processing method for fins 4 of a fin 4 processing device includes the following steps:

[0036] S1: Place the heat collecting tube 3 in the first support groove of the V-shaped plate 10. Place the fin 4 on the heat collecting tube 3. The fixing plate supports both ends of the fin 4. Start the motor 28 that controls the first lead screw 13 to rotate forward. The first lead screw 13 drives the first receiving plate 23 to move leftward. The pressing head 25 on the first receiving plate 23 is inserted into the heat collecting tube 3. Then, the partition plate 24 and the pressing head 25 push the fin 4 and the heat collecting tube 3 to continue moving leftward;

[0037] The pressing head 25 on the receiving plate 23 is inserted into the heat collecting tube 3, and then the partition plate 24 and the pressing head 25 push the fin 4 and the heat collecting tube 3 to continue moving leftward;

[0038] S2: The left sides of the heat collecting pipe 3 and the fin 4 respectively come into contact with the plug 26 and the baffle 27. The plug 26 is inserted into the left end of the heat collecting pipe 3, and the fin 4 is in contact with the baffle 27. Control the motor 28 of the first lead screw

[0039] 13 to continue rotating forward. The first receiving plate 23 continues to move leftward. The partition plate 24 and the pressing head

[0040] 25 push the fin 4 and the heat collecting pipe 3 to continue moving leftward. The limit plate 6 on the left side of the installation box 5 moves leftward. The limit plate 6 on the left side of the installation box 5 drives the double-layer gear

[0041] 30 to rotate through the transmission rack 31;

[0042] S3: The front limit plate 6 and the rear limit plate 6 of the installation box 5 will be driven by the double-layer gear 30 to move towards the middle at the same time, so that the front limit plate 6 and the rear limit plate 6 of the installation box 5 fix the front and rear sides of the fin 4. The pressing plate fixes the left end of the fin 4 through the ball 9. At this time, the motor 28 of the first lead screw 13 is turned off;

[0043] S4: Start the cooperating upper pressure roller 1 and lower pressure roller 2, so that the upper pressure roller 1 and the lower pressure roller 2 move leftward at the same time. When the upper pressure roller 1 and the lower pressure roller 2 move to the middle of the heat collecting pipe 3 and the fin 4, control the motor 28 of the second lead screw 29 to rotate forward. The second receiving plate 22 drives the support frame 15 to move leftward to the specified position. The air cylinder 14 pushes the push plate 16 to start working. The sliding sleeve 19 on the push plate 16 moves towards the middle at the same time. The sliding sleeve 19 is limited by the second transmission plate 21, and controls the first transmission plate 20 to drive the clamping plate 18 to move towards the middle at the same time to fix the right ends of the heat collecting pipe 3 and the fin 4;

[0044] S5: The upper pressing roller 1 and the lower pressing roller 2 continue to move to the left simultaneously until they both reach the leftmost end of the heat collecting pipe 3 and the fin 4. Then, reverse the motor 28 of the first lead screw 13. The first bearing plate 23 drives the partition plate 24 and the pressing head 25 to move to the right, separating the partition plate 24 and the pressing head 25 from the fin 4 and the heat collecting pipe 3 respectively. Again, reverse the motor 28 of the second lead screw 29 to make the first bearing plate 23 and the second bearing plate 22 move to the right at the same speed, separating the plug 26 and the baffle 27 from the fin 4 and the heat collecting pipe 3. After moving to the designated position, control the air cylinder 14 to drive the sliding sleeve 19 on the push plate 16 to move upward and downward simultaneously, and the clamping plate 18 is separated from the workpiece at the same time, and the work is completed.
