Description

Technical Field

[0002] In the manufacturing process of refrigeration equipment (such as refrigerators, air conditioners, etc.), the condenser is a key heat exchange component. Its bending forming accuracy directly affects the heat dissipation efficiency and service life of the equipment. The condenser needs to be bent during production. The advantage of the bent condenser is that it can increase the cooling contact area, extend the steam residence time, adapt to limited space and slight turbulence may be generated at the bend, breaking the laminar state of the steam and enhancing heat exchange.

[0003] The condenser can be bent in two ways: manually or automatically. With the advancement of technology, manual bending has gradually been replaced by automated bending equipment, which can place the condenser at the bending position and bend the condenser to a specific arc with the assistance of a push rod and a clamp.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-14 As shown, the present invention is a bending device for a condenser tube used in a refrigeration device, including: a hydraulic pressing push rod 1, a hydraulic bending push rod 2 provided on one side of the hydraulic pressing push rod 1, a push rod support plate 3 connected to the bottoms of the hydraulic pressing push rod 1 and the hydraulic bending push rod 2, and a functional base 4 and a rotating frame 5 placed in front of the hydraulic pressing push rod 1 and the hydraulic bending push rod 2. Among them, tracks are provided on the tops of the two groups of push rod support plates 3, and a moving slide 6 is slidably connected to the tracks, so that the moving slide 6 is connected to the output ends of the hydraulic pressing push rod 1 and the hydraulic bending push rod 2. The front section of the push rod support plate 3 at the bottom of the hydraulic bending push rod 2 is fixed to the surface of the rotating frame 5, and a rotation driving structure is provided at the bottom of the rotating frame 5. This rotation driving structure is a prior art. Through the rotation driving structure, the use angles of the hydraulic bending push rod 2 and the moving slide 6 at the front end of the hydraulic bending push rod 2 can be adjusted. The moving slide 6 connected to the hydraulic pressing push rod 1 is used to press the condenser tube against the side of the bending template 8 to keep the condenser tube stable during the bending process; As Figure 8 and Figure 9 shown, different from the prior art, the applicant internally installs an electric push rod in the functional base 4. The electric push rod can push the template assembly plate 9 on the top of the rotating frame 5 to move longitudinally. The position of the electric push rod does not conflict with the rotation driving structure connected to the rotating frame 5. Multiple groups of bending templates 8 can be stacked vertically on the template assembly plate 9, and the bending arcs of each group of bending templates 8 are different. Therefore, when the condenser tube is placed on the sides of the bending templates 8 at different positions, it can be bent into different arcs; For the bending of the condenser tube, template jacks 10 adapted to the condenser tube are provided on the side of each group of bending templates 8. After the condenser tube extends into the template jack 10 from the opening of the template jack 10 and reaches the bending position, the front end of the hydraulic pressing push rod 1 laterally presses the condenser tube at the template jack 10, while the front end of the hydraulic bending push rod 2 abuts against the bending part of the condenser tube to form a bend. At the front end of the moving slide 6, a pressing head plate 7 adapted to the bending of the condenser tube is attached, and the pressing head plate 7 and the moving slide 6 are connected by U-shaped parts for easy disassembly and assembly work later.

[0025] The discharge bin 23 is arranged on one side of the hydraulic pressing push rod 1. A closing bottom plate 24 is attached to the bottom port of the discharge bin 23. It should be noted that the bottom opening of the discharge bin 23 is inclined, and the closing bottom plate 24 is inclined upward at an angle when pressed against the opening of the discharge bin 23, as Figure 3 shown. The length of the closing bottom plate 24 is greater than the opening depth of the closing bottom plate 24. Therefore, the closing bottom plate 24 not only inclines upward, but also the front end of the closing bottom plate 24 will protrude from the opening of the closing bottom plate 24 to one side. The closing bottom plate 24 can be separated from the opening of the discharge bin 23 by pressing the exposed part by the long plate 28. The condenser tubes are longitudinally arranged in the discharge bin 23. At the same time, a storage bin 22 is provided at the top of the discharge bin 23 to increase the storage capacity of the condenser tubes. The condenser tubes fall along the inside of the discharge bin 23 under the action of gravity. The discharge bin 23 is integrally U-shaped and wraps the condenser tubes inside. At the same time, in order to prevent the condenser tubes from detaching from the front of the discharge bin 23, symmetric and inward extending parts are fixedly provided at the front end of the discharge bin 23. The extending parts can play a limiting role, and at the same time, one side of the discharge bin 23 is in a relatively open state, which is convenient for the operator to directly obtain the storage capacity of the condenser tubes in the discharge bin 23 from the side.

[0026] In order to make the closing bottom plate 24 stick to the bottom opening of the discharge bin 23 without external force to prevent the condenser tubes from falling off, the design is as Figure 6 and Figure 7As shown, a rotating sleeve column 25 is fixed to the back of the discharge bin 23, and an insert column extending into the cavity of the rotating sleeve column 25 is fixed at the end of the closed bottom plate 24. An arc spring portion 27 is installed in the cavity of the rotating sleeve column 25, and an adjustment bar 26 that fits with one end of the arc spring portion 27 is fixed on the surface of the closed bottom plate 24 extending into the cavity of the rotating sleeve column 25. The rotating sleeve column 25 is machined on the surface of the discharge bin 23 by bolts. Two groups of rotating sleeve columns 25 are provided, and concave cavities are provided on the opposite surfaces of the rotating sleeve columns 25. Two groups of insert columns are fixed at both ends of the closed bottom plate 24, and two groups of symmetrically distributed adjustment bars 26 are fixed on the surface of the insert columns. A rotating hole embedded in the front end of the closed bottom plate 24 is also provided in the cavity of the rotating sleeve column 25. The closed bottom plate 24 is fully extended to the rotating The movable sleeve column 25 is provided with one end of the arc spring portion 27 being hooked or fixed on the surface of the adjusting bar 26, and the other end of the arc spring portion 27 being connected to the convex plate extending inwardly in the cavity of the rotating sleeve column 25 in the same manner. When the arc spring portion 27 is not deformed, the closed bottom plate 24 is attached to the bottom opening of the discharge bin 23. When the closed bottom plate 24 is driven by an external force to separate from the bottom opening of the discharge bin 23, the adjusting bar 26 applies pressure to the arc spring portion 27 through the rotation of the closed bottom plate 24, so that the arc spring portion 27 gives the adjusting bar 26 a reverse driving force. After the external force of the closed bottom plate 24 disappears, the closed bottom plate 24 is pushed to a position attached to the bottom opening of the discharge bin 23 under the drive of the arc spring portion 27.

[0027] In order to peel off the closed bottom plate 24 and separate the condenser pipe in the discharge bin 23 from the opening, the design is as follows: Figure 3 , Figure 4 as well as Figure 5 As shown, a long toggle plate 28 is provided at a certain distance on one side of the closed bottom plate 24, and a short bearing plate 38 is fixedly provided at the bottom of the long toggle plate 28, and the short bearing plate 38 and the long toggle plate 28 are L-shaped as a whole, and the length of the short bearing plate 38 is shorter than the length of the long toggle plate 28, and in order to maintain the stability of the long toggle plate 28, a stabilizing cross bar 31 and a servo motor 30 are respectively connected to the side of the connection between the long toggle plate 28 and the short bearing plate 38, and the stabilizing cross bar 31 is rotated and intercepted, and the output end of the servo motor 30 is fixed to the long toggle plate 28, and the long toggle plate 28 can be rotated by the drive of the servo motor 30, and the stabilizing cross bar 31 is used as the support of the other side to maintain stability; For the transfer of the condenser tube, the toggle long plate 28 is rotated towards the closing bottom plate 24 by the drive of the servo motor 30. Since the front end of the closing bottom plate 24 is exposed, after the toggle long plate 28 rotates, its front end will abut against the exposed part of the closing bottom plate 24, and the toggle long plate 28 does not contact the discharge bin 23. The closing bottom plate 24 is pressed down by the toggle long plate 28 so that the toggle long plate 28 moves below the opening of the discharge bin 23. And when the toggle long plate 28 is at an inclined angle below the opening of the closing bottom plate 24, the condenser tubes in the discharge bin 23 naturally fall off and slide into the space between the toggle long plate 28 and the bearing short plate 38. Subsequently, the toggle long plate 28 rotates in the reverse direction to draw out the condenser tubes; During the above process, the closing bottom plate 24 and the bearing short plate 38 always remain in contact. When the toggle long plate 28 moves away from below the discharge bin 23, the closing bottom plate 24 returns to the position where it adheres to the bottom opening of the discharge bin 23, and the next group of condenser tubes can be blocked within the opening of the discharge bin 23 in time to complete the transfer of the condenser tubes.

[0028] The base of the servo motor 30 is connected to the connecting arm 29. After being bent, the connecting arm 29 is fixed to the outer wall of the discharge bin 23. Similarly, the stabilizing crossbar 31 is fixed to the outer wall of the discharge bin 23 after being bent, and the toggle long plate 28 is stably mounted on one side of the closing bottom plate 24. A set of disc support rods 35 is fixedly sleeved outside the stabilizing crossbar 31, and a linkage disc 34 is connected to the bottom end of the disc support rod 35. A jack is provided at the center of the linkage disc 34, and a part of the disc support rod 35 extends into the jack so that the linkage disc 34 can rotate freely; To assist in improving the stability after the condenser tubes are placed, as designed in Figure 4 and Figure 5As shown, a disk body positioning hole 36 is opened on the surface of the linkage disk 34, and an auxiliary support plate portion 37 is inserted into the groove of the disk body positioning hole 36. A connecting ear 32 is fixedly provided on the surface of the long plate 28, and an active rod 33 is rotatably connected to the surface of the connecting ear 32, and the auxiliary support plate portion 37 and the active rod 33 are respectively located on both sides of the linkage disk 34, and after the auxiliary support plate portion 37 is inserted through the disk body positioning hole 36, the threaded portion at the end is locked and fixed by a nut, and an arc portion is arranged on the top of the auxiliary support plate portion 37, which mainly plays the role of lifting the bottom of the condenser tube upward, wherein the bottom end of the active rod 33 is rotatably connected to the connection point of the linkage disk 34, and the active rod 33 is connected to the linkage The connection of the disk 34 is at the same position as the outer ring of the linkage disk 34. When the linkage disk 34 rotates, the long plate 28 can be synchronously rotated under the connection of the active rod 33. Under the active rotation of the long plate 28, the stabilizing cross bar 31 drives the active rod 33 to rotate. After the rotation of the linkage disk 34, the auxiliary support plate part 37 can be rotated to rotate from the lower end position attached to the condenser tube and separate from the condenser tube. When the auxiliary support plate part 37 is separated from the bottom of the condenser tube, it is worth noting that its stop position after leaving does not affect the normal front-to-back radial movement of the drive chamber 17 and the tube body side pressure plate 20 and the tube body bottom support plate 21 connected to the drive chamber 17. A push plate 15 is provided on one side of the discharge bin 23, and an electric screw rod 16 is installed at the bottom of the push plate 15, and the electric screw rod 16 is externally connected to the main support frame 14, and the push rod support plate 3 at the bottom of the hydraulic pressing push rod 1 is fixed to the surface of the main support frame 14, wherein the bottom of the push plate 15 can be moved laterally along the track on the main support frame 14 by the drive of the electric screw rod 16, so that the push plate 15 can move toward the template assembly plate 9 with the condensation pipe in front, and the track of the forward and backward movement of the push plate 15 is unobstructed; The design is shown in the template jack 10, wherein the drive bin 17 has a cavity, and the cavity is provided with a positive and negative threaded screw 18 and a screw outer bin 19 with a spacing distribution, wherein the screw outer bin 19 also has another set of positive and negative threaded screws 18 built in, so that the moving sleeves of the two sets of positive and negative threaded screws 18 are respectively connected to the two sets of tube bottom supporting plates 21 and the two sets of tube side pressure plates 20, so that the two sets of tube bottom supporting plates 21 and the tube side pressure plates 20 can be adjusted relative to each other, and the tube side pressure plates 2 0 is not fixed to the top of the tube bottom support plate 21, and the tube side pressure plate 20 is placed above the tube bottom support plate 21, and the bottom of the condenser tube is supported by the tube bottom support plate 21, and the arc-shaped groove area on the side of the two sets of tube side pressure plates 20 clamps the side of the condenser tube, so that one end of the condenser tube falling from the bearing short plate 38 is restricted between the two sets of tube side pressure plates 20, and the other side of the condenser tube is supported by the front arc portion of the auxiliary support plate portion 37. After the loading is completed, the bearing short plate 38 is moved away, and the auxiliary support plate portion 37 is also moved away to provide space for the movement of the push plate 15.

[0029] In order to achieve rapid adjustment of different bending angles, the design is as follows Figure 9 As shown, multiple groups of bending templates 8 are longitudinally stacked on the top of the template assembly plate 9, and the arcs of the bending points of each group of bending templates 8 are different. The surface of the template assembly plate 9 is provided with jacks. The upper end of the template assembly plate 9 is attached to the bending template 8. A positioning insertion rod 12 inserted into the jack is fixedly provided at the bottom of the bending template 8. A positioning hole 11 identical to the jack is provided at the top of the bending template 8. Corresponding locking holes 13 are provided on the surface of the template assembly plate 9 and the bending template 8. The stacked bending templates 8 are positioned by inserting the positioning insertion rod 12 into the positioning hole 11, so that the positions of the template jacks 10 of the stacked bending templates 8 are in the same vertical direction. Finally, a screw rod is longitudinally inserted into the locking hole 13. The locking hole 13 on the surface of the template assembly plate 9 has a threaded portion, which is adapted to the thread of the screw rod. Therefore, the positioning and installation of multiple groups of bending templates 8 are completed by the screw rod; In actual operation, the height of the bending template 8 can be adjusted by the electric push rod at the bottom of the template assembly plate 9, so that the template assembly plates 9 on different surfaces are placed at the bending height position of the condensate pipe, and different bending effects on the condensate pipe can be quickly adjusted.

[0030] In order to more accurately control the placement position of the condensate pipe, the design is as shown in the positioning hole 11 - the main support frame 14. A material plate opening 40 is provided on the side ground of the discharge bin 23. The inner wall of the discharge bin 23 is rotatably connected with a limit inner baffle 39 through a bearing short plate 38. The bottom of the limit inner baffle 39 is rotatably connected with an auxiliary vertical rod 42 through an auxiliary arm 41. An auxiliary cross bar 43 is fixedly provided at the top of the auxiliary vertical rod 42. An electric lead screw two 44 connected to the auxiliary cross bar 43 is installed on the surface of the discharge bin 23. The end position of the limit inner baffle 39 is the placement width of the condensate pipe, and it can also be adjusted according to the bottom spacing of the limit inner baffle 39, so that the device is applicable to different pipe lengths within a certain range. In order to adjust the end spacing of the limit inner baffle 39, the auxiliary cross bar 43 is synchronously driven to move longitudinally under the drive of the electric lead screw two 44. The longitudinal movement of the auxiliary cross bar 43 will pull the auxiliary vertical rod 42 to move. One end of the auxiliary arm 41 is rotatably connected to the opening at the bottom of the limit inner baffle 39, and the other end passes through the material plate opening 40 and is rotatably connected to the auxiliary vertical rod 42 outside. Therefore, under the connection of the auxiliary arm 41, the angle adjustment of the limit inner baffle 39 can be realized.

[0031] In order to assist in discharging, the front end of the discharge inclined plate 45 is placed at the front lower position of the pipe body bottom support plate 21. The two groups of pipe body bottom support plates 21 are far away from the condensate pipe after the rear bending and naturally fall onto the discharge inclined plate 45, and are discharged from the device through the inclination angle of the discharge inclined plate 45. And the vertical rod part of the pushing table plate 15 is located on the side of the pipe body bottom support plate 21 away from the discharge inclined plate 45. Therefore, the use of the discharge inclined plate 45 will not cause an obstructive influence on the radial movement of the pushing table plate 15.
