Description

Technical Field

[0001] This utility model relates to the field of PTFE welding equipment technology, specifically a PTFE hot and cold switching welding machine. Background Technology

[0002] The most prominent feature of PTFE membrane is its high strength. A medium-strength PTFE membrane is only 0.8 mm thick, but its tensile strength has reached the level of steel. Moreover, its low modulus of elasticity is conducive to forming complex curved shapes. It has a wide applicable temperature range, and can be used in the temperature range of -70℃ to 230℃. PTFE membrane needs to be welded during production.

[0003] For example, Chinese Patent Publication No. CN11161913A describes a PTFE membrane welding machine. This technical solution includes a base, a top box, and a limiting plate. The limiting plate is slidably connected to the top of the base, and there are two limiting plates arranged in parallel. Each of the two limiting plates has a fixing mechanism on its outer side for fixing the limiting plate. The top box is located above the base, and an L-shaped bracket is welded to one end of the top of the base. The top box is welded to one end of the top of the L-shaped bracket, and a first connecting rod and a second connecting rod are slidably connected to the bottom of the long side of the L-shaped bracket. A sliding plate is slidably connected inside the top box, and a lifting mechanism for raising and lowering the sliding plate is provided inside the top box.

[0004] However, the above-mentioned existing technical solutions have the following drawbacks: the technical solutions cannot cool the weld seam, and require an independent cooling machine to cool the weld seam, which reduces the finished product efficiency of PTFE membrane welding.

[0005] Therefore, we propose a PTFE hot and cold switching welding machine to solve the problems mentioned above. Utility Model Content

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.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a PTFE hot and cold switching welding machine, including: a support frame 1, an upper hoisting and lifting mechanism 4 on the support frame 1, an upper welding mechanism 5 connected to the lifting part of the lifting mechanism 4, a material carrier plate 3 and a lower welding mechanism 6 at the bottom of the support frame 1, the upper welding mechanism 5 including an upper hot mold 51 and an upper cold mold 52 that are mechanically driven to switch, and the lower welding mechanism 6 including a lower cold mold 63 and a lower hot mold 64 that can be switched. The upper hot mold 51 and the lower hot mold 64 cooperate to complete the welding of PTFE material, and the upper cold mold 52 and the lower cold mold 63 cooperate to complete the cooling after welding.

[0023] Specifically, the lifting mechanism 4 includes two symmetrical first linear slide rails 44. The upper end of the first linear slide rail 44 is fixedly connected to the upper end of the support frame 1. A rack 45 is slidably connected to the first linear slide rail 44. The lower end of the rack 45 is fixedly connected to the lifting seat 42. Two symmetrical first linear cylinders 41 are arranged between the lifting seat 42 and the support frame 1. The first linear cylinders 41 drive the lifting seat 42 to rise and fall. The lower end of the lifting seat 42 is rotatably connected to the upper welding mechanism 5. An upper hot and cold mold switching drive structure 49 is arranged between the lifting seat 42 and the upper welding mechanism 5.

[0024] A fixing plate 48 is symmetrically fixedly installed on the upper end of the support frame 1. A connecting rod 46 is rotatably connected between the two fixing plates 48. Two gears 47 are installed on the connecting rod 46. The gears 47 mesh with the rack 45. When the first linear cylinder 41 drives the lifting seat 42 to rise and fall, the rack 45 moves up and down, driving the gears 47 to rotate. The two gears 47 are synchronized through the connecting rod 46, thereby making the two racks 45 move up and down synchronously, maintaining the horizontality of the lifting seat 42 during the lifting process.

[0025] A second lifting bracket 521 is fixedly installed on the upper cold mold 52, and a first lifting bracket 511 is fixedly installed on the upper hot mold 51. The second lifting bracket 521 and the first lifting bracket 511 are coaxially and integrally fixedly connected, and the second lifting bracket 521 and the first lifting bracket 511 form a 45° angle. By driving the rotation of the second lifting bracket 521 and the first lifting bracket 511, the upper hot mold 51 and the upper cold mold 52 are switched.

[0026] The upper hot and cold mold switching drive structure 49 is mainly composed of a second linear cylinder 491. The upper end of the second linear cylinder 491 is rotatably connected to the lifting seat 42, and the telescopic end of the second linear cylinder 491 is rotatably connected to the first hoisting bracket 511. The telescopic drive of the second linear cylinder 491 drives the first hoisting bracket 511 and the second hoisting bracket 521 to rotate 45° relative to the lifting seat 42 to switch between hot and cold molds.

[0027] The lower welding mechanism 6 includes a base plate 62, on which a second linear slide rail 66 is provided. A sliding seat 65 is slidably connected to the second linear slide rail 66. A lower cold mold 63 and a lower hot mold 64 are arranged in parallel on the sliding seat 65. The sliding seat 65 is connected to a third linear cylinder 61. The third linear cylinder 61 drives the sliding seat 65 to move on the second linear slide rail 66, thereby realizing the linear movement of the lower cold mold 63 and the lower hot mold 64 and switching between the lower cold and hot molds.

[0028] Working principle: PTFE material is placed in the material carrier plate 3, and the welding joint is fixed between the upper welding mechanism 5 and the lower welding mechanism 6. First, the upper hot mold 51 and the lower hot mold 64 are aligned. The lifting mechanism 4 drives the upper welding mechanism 5 to descend. The upper hot mold 51 and the lower hot mold 64 clamp the material for welding. After welding is completed, the lifting mechanism 4 drives the upper welding mechanism 5 to rise, and the upper cold mold 52 and the lower cold mold 63 are aligned. The lifting mechanism 4 drives the upper welding mechanism 5 to descend again. The weld is cooled by the upper cold mold 52 and the lower cold mold 63 clamping the weld.
