Description

Technical Field

[0001] The present application relates to the technical field of glass fiber manufacturing, and in particular to a device for rapidly welding cooling fins. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance. Glass fiber is made by melting a variety of mineral raw materials at high temperature into liquid glass, and the liquid glass flows into the drawing device for drawing. After that, it is also made through processes such as winding and weaving. During the glass fiber drawing process, the glass fiber filaments flow out from the nozzle and pass between the two cooling fins of the leak plate cooler for cooling. The glass fiber filaments transfer heat to the cooling fins by radiation, and the glass fiber filaments are quickly cooled.

[0003] The leak plate cooler includes cooling fins and copper square tubes. The cooling fins are welded on the copper square tubes. The cooling fins transfer heat to the copper square tubes through heat transfer, and the copper square tubes take away the heat through coolant. In the existing technology, the welding between the cooling fins and the copper square tubes is mainly manual welding. If workers are required to quickly weld the cooling fins, it is inevitable that the spacing between the two cooling fins after welding will be uneven. The distance between the glass fiber yarn and the two cooling fins will affect the cooling effect of the glass fiber yarn. The uneven spacing between the cooling fins will cause the fiber roots at the leak nozzle to produce "pulsation" or "flash flow" when the glass fiber yarn passes between the two cooling fins, thereby reducing the product yield.

[0004] In view of the above problems, a device for quickly welding cooling fins is now designed. Summary of the Invention

[0039] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] An embodiment of the present application provides a device for quickly welding cooling fins, which can solve the problem of uneven welding of cooling fins in the related art.

[0041] See also Figures 1 to 9, a device for quickly welding cooling fins, comprising: a copper square tube 1, a placement block 3, a plurality of guide tubes 6 and a guide block 8, the copper square tube 1 is provided with a plurality of placement slots 2 for placing cooling fins, the placement block 3 is provided with a detachable baffle 4, the placement block 3 and the baffle 4 form a positioning area for placing the copper square tube 1, two support rods 5 are provided on both sides of the top of the placement block 3, one end of the plurality of guide tubes is connected to a furnace 7, the other end of the plurality of guide tubes 6 is located in the positioning area, the guide tube 6 is used to guide the silver-based solder into the placement slot 2 into the guide block 8, the guide block 8 is mounted between the two support rods 5, the guide block 8 has a plurality of mounting through holes 9 arranged evenly in sequence, and the guide block 8 is provided with a plurality of regular structures 10, the regular structure 10 including: two clamping plates 101 and two extension plates 102, the two clamping plates 101 are relatively slidably connected in the mounting through holes 9, there is a guide space between the two clamping plates 101 for guiding the cooling fin to be inserted into the placement slot 2, the clamping plates 101 are provided with an extension slot 11, the two extension plates 102 correspond to the two clamping plates 101 one by one, and the extension plates 102 are slidably connected in the extension slot 11, and there is an auxiliary space between the two extension plates 102 to continue the function of the guide space;

[0042] During implementation, a guide block 8 is installed on the support rod 5, and the spacing between the two clamping plates 101 is adjusted according to the thickness of the cooling fin to be welded as needed, that is, the size of the guide space is adjusted so that the cooling fin can just enter the guide space from top to bottom. After entering the guide space, the cooling fin is inserted into the placement groove 2 along the direction in which the guide space extends. Since the mounting through holes 9 are arranged evenly in sequence, the guide spaces are arranged evenly on the guide block 8 in sequence. When multiple cooling fins are inserted into multiple guide spaces, the multiple cooling fins are all inserted into the placement groove 2 along the direction in which the guide space extends and all the cooling fins are evenly arranged. At this time, the multiple cooling fins are pressed to fix the multiple cooling fins in the position of the placement groove 2. The silver-based solder is melted into liquid by the melting furnace 7. The guide tube 6 guides the silver-based solder into the placement groove 2, and the silver-based solder welds the multiple cooling fins to the copper square tube 1.

[0043] It should be pointed out that the extension plate 102 slides out from the clamping plate 101 according to the thickness of the cooling fin. When the cooling fin to be welded is too thin and the guide space is far away from the placement slot 2, the cooling fin will deviate from the extension direction of the guide space when inserted into the placement slot 2. When the extension plate 102 is extended, the auxiliary space is equivalent to extending the length of the guide space, which better helps the cooling fin to be evenly inserted into the placement slot 2.

[0044] Specifically, in this embodiment, the regular structure 10 further includes two connecting rods 103, two sliders 104 and a rotating disk 105;

[0045] The two connecting rods 103 are connected to the two sliders 104 in a one-to-one correspondence, and the two connecting rods 103 are connected to the two clamping plates 101 in a one-to-one correspondence. The rotating disk 105 is provided with a chute 12 for synchronously driving the two clamping plates 101 to move away from or approach each other at the same time, and the two sliders 104 are slidably connected in the chute 12;

[0046] The connecting rod 103 drives the clamping plate 101 to move in the installation hole 9, and the sliding groove 12 is shown on the rotating disk 105 as follows. Figure 5 As shown in the shape, when the rotating disk 105 rotates, the two sliders 104 slide in the slide groove 12 and the two sliders 104 slide synchronously. When the sliders 104 drive the two connecting rods 103 and the splint 101 to move, the two splints 101 can move away from or approach each other at the same time.

[0047] More specifically, in this embodiment, the regular structure 10 further includes a first gear 106 and a second gear 107;

[0048] The first gear 106 is meshed with the second gear 107 , the first gear 106 is connected to the rotating disk 105 , and the second gears 107 are connected via a round rod 13 , which is driven by a motor;

[0049] The round rod 13 is connected to the output end of the motor, and the motor drives the round rod 13 to rotate. The round rod 13 drives the plurality of second gears 107 to rotate synchronously, so that the first gear 106 is driven to rotate by the second gear 107. Since the plurality of second gears 107 rotate synchronously, the plurality of first gears 106 rotate synchronously. That is, the rotation of the round rod 13 can be controlled by the motor, and the plurality of splints 101 and the plurality of extension plates 102 can be further controlled and adjusted according to the thickness of the cooling fin.

[0050] Furthermore, in this embodiment, the regular structure 10 further includes two threaded rods 108 and two sleeves 109;

[0051] The two threaded rods 108 are connected to the two extension plates 102 in a one-to-one correspondence, and the two threaded rods 108 are connected to the two sleeves 109 in a one-to-one correspondence. The threaded rods 108 are threadedly connected to the sleeves 109;

[0052] The extension plate 102 cannot be separated from the clamping plate 101 and the threaded rod 108 is connected to the extension plate 102 . The threaded rod 108 can be controlled to extend and retract by rotating the sleeve 109 , thereby controlling the extension plate 102 to slide on the clamping plate 101 .

[0053] Furthermore, in this embodiment, a driving structure is provided in the clamping plate 101 , and the driving structure drives the sleeve 109 to rotate. The driving structure includes a third gear 141 and a gear slot 142 ;

[0054] The inner side surface of the mounting through hole 9 is provided with a rack groove 15, the gear groove 142 is located on the side surface of the clamping plate 101, the third gear 141 is installed in the gear groove 142, and the third gear 141 is meshed with the rack groove 15;

[0055] When the clamping plate 101 moves in the mounting through hole 9 , the third gear 141 also moves in the gear slot 142 and the third gear 141 rotates according to the movement amplitude of the clamping plate 101 .

[0056] Preferably, in this embodiment, the driving structure further includes a first track wheel 143, a second track wheel 144 and a track 145;

[0057] The first track wheel 143 is connected to the sleeve 109 , the second track wheel 144 is connected to the third gear 141 , and the first track wheel 143 and the second track wheel 144 are connected via a track 145 ;

[0058] The second track wheel 144 drives the first track wheel 143 to rotate through the track 145. When the splint 101 moves, the third gear 141 drives the second track wheel 144 to rotate, and then the second track wheel 144 drives the first track wheel 143 to rotate, and the first track wheel 143 drives the sleeve 109 to rotate, that is, the extension plate 102 will synchronously extend and retract during the movement of the splint 101. Specifically, when the two splints 101 are close to each other, that is, the cooling fins are thinner, the extension plate 102 will synchronously extend; when the two splints 101 are away from each other, that is, the cooling fins are thicker, the extension plate 102 will synchronously retract.

[0059] In a preferred embodiment, a pressure plate 16 is provided above the guide block 8, and the pressure plate 16 is slidably connected to the two support rods 5. The pressure plate 16 is provided on the support rods 5 to squeeze the cooling fins and fix the cooling fins at a limiting position;

[0060] After the cooling fins are inserted into the placement groove 2 , the pressing plate 16 squeezes the cooling fins so that the cooling fins are tightly attached to the bottom of the placement groove 2 , making it convenient to subsequently weld the cooling fins to the copper square tube 1 using silver-based solder.

[0061] In this embodiment, the top of the support rod 5 is provided with a thread and the support rod 5 is rotatably connected to the placement block 3, and the support rod 5 is threadedly connected to the pressure plate 16;

[0062] The top of the support rod 5 is provided with a socket 17, and a detachable knob 18 is provided in the socket 17;

[0063] The support rod 5 is driven to rotate by the knob 18 . After a plurality of cooling fins are inserted into the placement slot 2 , the pressing plate 16 is pressed onto the plurality of cooling fins by rotating the two support rods 5 , thereby fixing the plurality of cooling fins in the placement slot 2 .

[0064] In this embodiment, a plug 19 is connected to the bottom of the knob 18, the socket 17 is non-cylindrical and the plug 19 can be inserted into the socket 17;

[0065] The socket 17 is a non-cylindrical opening. When the pin 19 is inserted into the socket 17, the knob 18 rotates to drive the support rod 5 to rotate. After the pressure plate 16 is installed on the support rod 5, the pin 19 is inserted into the socket 17 and rotated to avoid the situation where the pressure plate 16 and the support rod 5 cannot be disassembled.

[0066] Here's how this application works:

[0067] During implementation, a guide block 8 is installed on the support rod 5, and a motor is used to adjust the distance between the two clamping plates 101 and the extension plate 102 according to the thickness of the welded cooling fins as needed, that is, the size of the guide space is adjusted so that the cooling fins can just enter the guide space from top to bottom. After entering the guide space, the cooling fins are inserted into the placement groove 2 along the direction in which the guide space extends. Since the mounting through holes 9 are evenly arranged in sequence, the guide spaces are evenly arranged on the guide block 8 in sequence. When multiple cooling fins are inserted into multiple guide spaces, the multiple cooling fins are all inserted into the placement groove 2 along the direction in which the guide spaces extend, and all cooling fins are evenly arranged.

[0068] At this time, the pressure plate 16 is installed on the support rod 5, and then the plug 19 is inserted into the socket 17. The plug 19 rotates to drive the support rod 5. The pressure plate 16 presses on the cooling fins, so that the cooling fins are fixed in the position of the placement groove 2. The silver-based solder is melted into liquid by the melting furnace 7. The guide tube 6 guides the silver-based solder into the placement groove 2. The silver-based solder solder welds the cooling fins to the copper square tube 1;

[0069] It should be noted that when the cooling fin to be welded is too thin and the guide space is far away from the placement slot 2, the cooling fin may deviate from the direction in which the guide space extends when inserted into the placement slot 2. When the extension plate 102 is extended, the auxiliary space is equivalent to extending the length of the guide space, which better helps the cooling fin to be evenly inserted into the placement slot 2.

[0070] The extension plate 102 adjusts its telescopic length synchronously according to the movement of the clamping plate 101. Specifically, when the two clamping plates 101 are close to each other, that is, the cooling plate is thinner, the extension plate 102 will extend synchronously; when the two clamping plates 101 are away from each other, that is, the cooling plate is thicker, the extension plate 102 will retract synchronously.
