[0002] Copper tube bending can be achieved through methods such as using a tube bender, heat annealing, manual bending, sand-filled bending, and lead-filled bending.

[0003] However, existing square-groove copper tube bending devices have the following problems during use: When processing square-groove U-shaped copper tubes in the traditional way, the U-shaped square-groove copper tube is usually disassembled into two parts, upper and lower. The copper block is used for machining to remove the water passage and square groove dimensions inside the copper tube. Then, it is welded together using high temperature welding. The welding time is long and the component cost is high. In addition, the press press does not have shock absorption and buffer, which can easily lead to damage to the copper tube. Utility Model Content

[0004] The purpose of this utility model is to provide a square-groove copper tube bending device to solve the related problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a square-groove copper tube bending device, comprising a base, a lower fixing seat, and a press. The lower fixing seat is installed at the top of the base, and a guide rod is installed at the top of the lower fixing seat. An upper fixing seat is installed at the top of the guide rod, and a press is installed at the top of the upper fixing seat. A push block penetrating the guide rod is installed at the output end of the press. An aluminum alloy upper die is installed inside the push block. A slide rail is installed at the top of the lower fixing seat, and a moving block is installed inside the slide rail. An aluminum alloy bottom die is installed at the top of the moving block, and a transverse groove is formed on the inner wall of the aluminum alloy bottom die. A U-shaped groove is formed on the inner wall of the aluminum alloy bottom die. A hydraulic groove is formed inside the lower fixing seat, and a shock-absorbing mechanism for buffering the pressure at the aluminum alloy bottom die is provided inside the hydraulic groove. An installation groove is formed inside the push block, and an installation mechanism for fixing the aluminum alloy upper die is provided inside the installation groove.

[0006] This technical solution provides a square-groove copper tube bending device, wherein a second spring is sleeved on the outer wall of the guide rod.

[0007] This technical solution provides a square-groove copper tube bending device. The shock absorption mechanism includes a holding column and a floating plate. The holding column is connected to the moving block inside the hydraulic groove. The bottom end of the holding column is equipped with a floating plate that is adapted to the inner wall of the hydraulic groove. The top end of the hydraulic groove is equipped with a sealing gasket that fits against the outer wall of the holding column. The outer wall of the holding column is fitted with a first spring.

[0008] This technical solution provides a square-groove copper tube bending device, wherein the floating plate has through holes inside.

[0009] This technical solution provides a square-groove copper tube bending device, wherein rubber blocks are installed on the outer walls of the push block and the moving block.

[0010] This technical solution provides a square-groove type copper tube bending device. The installation mechanism includes a movable groove and a pull rod. Movable grooves are provided at both ends of the installation groove, and a pull rod that penetrates the upper aluminum alloy mold is provided inside the movable groove. A third spring is sleeved on the outer wall of the pull rod.

[0011] Compared with the prior art, this utility model provides a square groove copper tube bending device, which has the following beneficial effects:

[0012] 1. This utility model uses a rubber block moving within the slide rail to compress the first spring. Simultaneously, the holding column moves the float downwards, causing hydraulic oil in the hydraulic groove to flow upwards through the through hole. Since the sealing gasket can seal the hydraulic groove, it achieves a good sealing effect. Because the first and second springs are both elastic elements, they can achieve a shock absorption effect under their own elastic force. Furthermore, the float plate floats within the hydraulic groove, which further enhances the buffering and shock absorption effect.

[0013] 2. In this utility model, the upper aluminum alloy mold is inserted into the mounting groove, thereby pressing the position of the pull rod and causing the third spring to tighten. When the upper aluminum alloy mold moves to the position of the outer wall groove aligned with the pull rod, the pull rod is fixed to the outer wall of the upper aluminum alloy mold under the elastic force of the third spring, which facilitates the installation and fixation of the upper aluminum alloy mold in the position of the push block.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1, such as Figure 1-2As shown, this utility model provides a technical solution: a square-groove copper tube bending device, including a base 1, a lower fixing seat 2, and a press 7. The lower fixing seat 2 is installed at the top of the base 1, and a guide rod 5 is installed at the top of the lower fixing seat 2. An upper fixing seat 6 is installed at the top of the guide rod 5, and a press 7 is installed at the top of the upper fixing seat 6. A push block 8 penetrating the guide rod 5 is installed at the output end of the press 7. An aluminum alloy upper die 10 is provided inside the push block 8. A slide rail 3 is installed at the top of the lower fixing seat 2. The internal part of the device includes a movable block 4, with an aluminum alloy bottom mold 11 mounted on its top. The inner wall of the aluminum alloy bottom mold 11 has a transverse groove 12 and a U-shaped groove 13. The lower fixed seat 2 has a hydraulic groove 16 inside, and a shock-absorbing mechanism for buffering pressure at the aluminum alloy bottom mold 11 is installed inside the hydraulic groove 16. A second spring 22 is sleeved on the outer wall of the guide rod 5. The shock-absorbing mechanism includes a pressure-holding column 17 and a floating plate 18. The hydraulic groove 16 has a pressure-holding column connected to the movable block 4 inside. 17. A float plate 18 adapted to the inner wall of the hydraulic groove 16 is installed at the bottom of the holding column 17. A sealing gasket 19 that fits against the outer wall of the holding column 17 is installed at the top of the hydraulic groove 16. A first spring 20 is sleeved on the outer wall of the holding column 17. A through hole 21 is opened inside the float plate 18. Rubber blocks 15 are installed on the outer walls of the push block 8 and the moving block 4. When the press machine 7 is started, the upper aluminum alloy mold 10 pushes the push block 8 to press the copper ring 14 in the U-shaped groove 13. Then the second spring 22 is compressed downward and then moves downward. The moving block 4 moves within the slide rail 3 via the rubber block 15, causing the first spring 20 to contract. At the same time, the holding column 17 drives the float plate 18 to move downward, causing the hydraulic oil in the hydraulic groove 16 to flow upward from the through hole 21. Since the sealing gasket 19 can seal the hydraulic groove 16, it achieves a good sealing effect. Since the first spring 20 and the second spring 22 are both elastic elements, they can play a shock-absorbing role under their own elastic force. The float plate 18 floats within the hydraulic groove 16, which facilitates the improvement of the buffering and shock-absorbing effect.

[0021] Example 2, as Figure 1-4 As shown, this utility model provides a technical solution: a square-groove copper tube bending device, including a push block 8 with an installation groove 9 inside, and an installation mechanism for fixing an aluminum alloy upper mold 10 inside the installation groove 9. The installation mechanism includes a movable groove 23 and a pull rod 24. Movable grooves 23 are provided at both ends of the installation groove 9, and a pull rod 24 that penetrates the aluminum alloy upper mold 10 is provided inside the movable groove 23. A third spring 25 is sleeved on the outer wall of the pull rod 24. The aluminum alloy upper mold 10 is inserted into the installation groove 9, and then the aluminum alloy upper mold 10 squeezes the pull rod 24, causing the third spring 25 to contract. Then, under the elastic force of the third spring 25, the pull rod 24 is fixed to the outer wall of the aluminum alloy upper mold 10, which facilitates the fixing of the position of the aluminum alloy upper mold 10 in the push block 8.

[0022] Working principle: First, connect the external power supply. The operator inserts the aluminum alloy upper mold 10 into the mounting groove 9, thereby pressing the position of the pull rod 24, causing the third spring 25 to contract. When the aluminum alloy upper mold 10 moves to the position of the outer wall groove aligned with the pull rod 24, the pull rod 24 is fixed to the outer wall of the aluminum alloy upper mold 10 under the elastic force of the third spring 25, which facilitates the fixation of the aluminum alloy upper mold 10 in the position of the push block 8. At this time, the operator places the copper ring processing part 14 into the aluminum alloy bottom mold 11. Then, the press 7 is started to push the aluminum alloy upper mold 10 at the push block 8 to press the copper ring processing part 14 into the U-shaped groove 13. The press 7 slowly presses the copper ring processing part 14 into the U-shaped groove 13 at a pressure of 50 N / s. The square-groove copper tube is slowly pressed into a square-groove U-shaped copper tube. At the same time, the push block 8 squeezes the second spring 22, causing the second spring 22 to contract downwards. Then, the downward moving block 4 moves within the slide rail 3 via the rubber block 15, causing the first spring 20 to contract. Simultaneously, the holding column 17 drives the float plate 18 to move downwards, causing the hydraulic oil in the hydraulic groove 16 to flow upwards from the through hole 21. Since the sealing gasket 19 can seal the hydraulic groove 16, it achieves a good sealing effect. Since the first spring 20 and the second spring 22 are both elastic elements, they can achieve a shock absorption effect under their own elastic force. The float plate 18 floats within the hydraulic groove 16, which facilitates the improvement of the buffering and shock absorption effect.

[0023] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
