[0034] like Figure 1-7As shown, the present invention proposes a copper tube shaping machine, including a workbench 1, a shaping mechanism 2, a blocking component 3, a clamping mechanism 4 and a guide shaft 5. A driving mechanism 6 is provided on one side of the workbench 1; the driving mechanism 6 adopts a gas-liquid booster cylinder, which is fixed on the workbench 1 by bolts, and the clamping mechanism 4 is arranged on the workbench 1 and is connected with the driving mechanism 6 in a transmission manner. A panel 7 is arranged on the workbench 1, and a controller 8 arranged on the panel 7 is electrically connected with the driving mechanism 6. The present invention pushes the clamping mechanism 4 to move through the driving mechanism 6, so that the clamping mechanism 4 acts on the shaping mechanism 2, thereby extruding and shaping the copper tube. The structure is compact and the volume is small. A semi-automatic method is adopted, which reduces the intensity of manual operation and improves the shaping efficiency. The shaping mechanism 2 and the clamping mechanism 4 are limitedly installed through the guide shaft 5 to improve the shaping accuracy.

[0035] In this embodiment, if Figure 1-5 As shown, the shaping mechanism 2 is placed on the workbench 1, and the shaping mechanism 2 includes a partition 201 and a pressure plate 202. A plurality of partitions 201 and a plurality of pressure plates 202 are alternately arranged left and right along the length direction of the workbench 1, wherein both ends of the shaping mechanism 2 are pressure plates 202, and the blocking assembly 3 and the clamping mechanism 4 are respectively against the pressure plates 202 on both sides; the upper end surface of the pressure plate 202 protruding upward from the partition 201 is provided with a shaping protrusion 9, so that a shaping cavity 10 is formed between two adjacent shaping protrusions 9 and the upper end surface of the partition 201, and the copper tube to be shaped is placed in the shaping cavity 10, and the guide shaft 5 passes through the guide groove 11 provided on the partition 201 and the pressure plate 202 to fix the position of the shaping mechanism 2 on the workbench 1.

[0036] like Figure 3 As shown, the present invention comprises a plurality of partitions 201 and a plurality of pressing plates 202 which are alternately arranged, and a shaping cavity 10 for placing the copper tube is formed between the shaping protrusions 9 arranged on two adjacent pressing plates 202 and the upper end surface of the partition 201, so that copper tubes of different lengths can be shaped by adding partitions 201 or pressing plates 202 or reducing partitions 201 or pressing plates 202, and pressing plates 202 and partitions 201 of different widths can also be replaced to achieve the effect of shaping copper tubes of different widths and different pitches.

[0037] like Figure 2 As shown, the blocking assembly 3 is arranged on the workbench 1, and the blocking assembly 3 includes a blocking seat 301 and a sealing plate 302. The blocking seat 301 is fixed to the workbench 1 and fits with the rightmost pressure plate 202. A slot 12 is provided along the length direction of the blocking seat 301, and the sealing plate 302 is arranged on the outer side of the blocking seat 301 and seals the slot 12. The end of the guide shaft 5 inserted in the inner position of the slot 12 is tightly pressed against the sealing plate 302, and the other end of the guide shaft 5 passes through the guide groove 11 of the partition 201 and the pressure plate 202, and the slot 12 is coaxially arranged with the guide groove 11.

[0038] like Figure 2 As shown, the clamping mechanism 4 includes a clamping seat 401, a pressure cover 402, a slider 403 and an adjusting pressure block 404. The pressure cover 402 passes through the telescopic rod of the driving mechanism 6 and is locked by setting a ball head nut 405. The pressure cover 402 is fixedly connected to the clamping seat 401. The pressure cover 402 is fixed to the telescopic rod of the driving mechanism 6 by the ball head nut 405, and then the pressure cover 402 is fixedly connected to the clamping seat 401, thereby ensuring the stability of the connection between the telescopic rod and the clamping seat 401, and facilitating the disassembly and replacement of components; the workbench 1 is located at the shaping mechanism 2 is provided with guide rails 406 on both sides, the slider 403 is slidably connected to the guide rails 406, the pressing seat 401 is fixedly connected to the slider 403, and the adjusting pressing block 404 is arranged between the pressing seat 401 and the shaping mechanism 2, so that the adjusting pressing block 404 is pressed by the pressing seat 401 to press the shaping mechanism 2, and the force is transmitted to the adjusting pressing block 404 through the pressing seat 401, and then the shaping mechanism 2 is squeezed by the adjusting pressing block 404, so that the pressure plate 202 and the partition plate 201 are evenly stressed during squeezing, thereby improving the shaping accuracy and achieving the purpose of copper tube shaping.

[0039] Furthermore, in order to facilitate the assembly of the adjusting block 404, a U-shaped groove 13 is provided at the position of the adjusting block 404 corresponding to the guide shaft 5. Through this structure, after the guide shaft 5 is inserted into the clamping seat 401, the U-shaped groove 13 of the adjusting block 404 can be placed corresponding to the guide shaft 5.

[0040] The end of the guide shaft 5 extending out of the shaping mechanism 2 is inserted into the clamping seat 401. The clamping seat 401 is provided with a slot 14 at the radially movable position opposite to the guide shaft 5, so that the guide shaft 5 moves in the slot 14 when the clamping seat 401 moves, avoiding position interference between the guide shaft 5 and components, so that the guide shaft 5 can move more smoothly.

[0041] The workbench 1 is provided with a groove 15 at the position where the clamping seat 401 moves radially, and the clamping seat 401 is extended into the groove 15 and provided with an extension portion 16. This structure increases the contact area between the clamping seat 401 and the adjusting block 404, and at the same time makes the adjusting block 404 more evenly subjected to the force of the clamping seat 401.

[0042] In this embodiment, the shaping protrusion 9 extends from the end of one side of the pressure plate 202 in the length direction to the other side. Through this structure, the bending parts at both ends of the copper tube can be placed outside the shaping cavity 10, which is convenient for checking the placement of the copper tube and avoiding position interference during operation.

[0043] Furthermore, the guide shaft 5 is clearance-matched with the guide grooves 11 of the pressure plate 202 and the partition 201. Meanwhile, the guide groove 11 of the pressure plate 202 has a circular cross-section, while the guide groove 11 of the partition 201 has a runway cross-section. This structure allows sufficient movement between the pressure plate 202 and the partition 201 when they are squeezed.

[0044] Exemplarily, the blocking seat 301 is provided with at least two slots 12, and a guide shaft 5 is inserted in each slot 12, each guide shaft 5 is inserted into the clamping seat 401, the front and rear end surfaces of the pressure plate 202 and the partition 201 are arranged flush, and the slots 12 are symmetrically distributed around the center of the pressure plate 202 and the partition 201, so that the positioning effect of the pressure plate 202 and the partition 201 is guaranteed by multiple guide shafts 5, and at the same time, the position stability of the clamping seat 401 and the pressure block when they are moved under force is ensured, thereby ensuring the clamping effect of the pressure plate 202 and the partition 201.

[0045] When in use, the S-shaped copper tube to be shaped is placed in the shaping cavity 10 formed by the shaping protrusions 9 of the two adjacent pressing plates 202 and the upper end surface of the partition 201. At this time, the partition 201 and the pressing plate 202 are in a loose state, and the different deformed parts of the copper tube will open a certain gap between the partition 201 and the two pressing plates 202, so that the shaping cavity 10 is in an irregular state. After placing the copper tube, it is necessary to press the two controllers 8 on the panel 7 with both hands at the same time, and the gas-liquid booster cylinder will work; then the telescopic rod of the gas-liquid booster cylinder pushes the clamping seat 401 to move on the guide rail 406, and when the clamping seat 401 moves to a certain position, it pushes the adjusting block 40 4 moves, and the leftmost pressing plate 202 is squeezed by the adjusting pressing block 404, while the rightmost pressing plate 202 is blocked by the blocking seat 301 and does not move. Finally, as the adjusting pressing block 404 continues to move, the pressing plate 202 and the partition 201 are squeezed, so that the pitch of the copper tube becomes the center distance between the pressing plate 202 and the partition 201, so as to achieve the effect of shaping the copper tube. The copper tubes of different lengths can be shaped by adding partitions 201 or pressing plates 202 or reducing partitions 201 or pressing plates 202. At the same time, the pressing plates 202 and partitions 201 of different widths can also be replaced to achieve the effect of shaping copper tubes of different widths and different pitches.

[0046] In another embodiment, Figure 7 As shown, the workbench 1 is provided with a protective cover 17 to cover the clamping mechanism 4, wherein the adjusting pressure block 404 passes through the groove provided in the protective cover 17 to extrude the shaping mechanism 2; the clamping mechanism 4 is protected by the protective cover 17, and at the same time, personal injury caused by misoperation of extending into the clamping mechanism 4 is avoided, thereby improving the safety of use.

[0047] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
