Technical Field
[0001] The utility model relates to the technical field of expansion joint processing, in particular to a bellows expansion joint processing device. Background Art
[0002] Metal bellows are pipes with a regular wave-like appearance. Commonly used metal bellows include carbon steel, stainless steel, steel with plastic lining, aluminum, and others. They are primarily used for applications requiring a very small bending radius, non-concentric axial transmission, irregular turns, expansions, or to absorb thermal deformation of pipes, or for connecting pipes to other pipes or equipment where fixed elbows are inconvenient to install. During the production process, metal bellows are often clamped onto the metal pipe using two blocks with semicircular grooves. The heated metal pipe is then extruded by an external extrusion device and blocked by the blocks, forming an expansion joint on the metal pipe.
[0003] Usually a hydraulic cylinder is needed to extrude the heated metal pipe. During the extrusion process, the hydraulic cylinder will be exposed to the heat of the metal pipe. Prolonged heating can easily cause damage to the hydraulic cylinder, so it can be improved. Utility Model Content

[0026] The fixing unit 100 includes a base 101, a side plate 102 is slidably mounted on the top of the base 101, a clamping assembly 103 is provided on the top of the base 101, a metal tube 104 is attached to one side of the side plate 102, the metal tube 104 supports the expansion joint by heating and pressing, and a bottom support 105 is attached to the bottom of the metal tube 104;
[0027] The extrusion unit 200 includes a hydraulic cylinder 201, which provides pressing power. The hydraulic cylinder 201 is fixedly installed on the top of the base 101. A water plate 202 is fixedly installed at one end of the hydraulic cylinder 201. An elastic tube 203 is fixedly connected to one side of the water plate 202. The elastic tube 203 provides retractability and provides movement space for the side plate 102. One end of the elastic tube 203 is fixedly connected to a pipe 204. A water pump 205 is fixedly installed at the bottom of the pipe 204. One side of the water pump 205 is fixedly connected to a water tank 206. One side of the water tank 206 is fixedly connected to a connecting pipe 207. A fan group 208 is rotatably installed on the top of the water tank 206. The fan group 208 dissipates heat for the water inside the water tank 206. An auxiliary heat dissipation component 209 is provided at one end of the connecting pipe 207. A cooler 210 is fixedly installed inside the water tank 206 to cool the water inside the water tank 206 through the cooler 210.
[0028] Among them, a slide plate is fixedly installed on the top of the base 101, and the side plate 102 is slidably installed on the inner wall of the slide plate. The side plate 102 is fixedly installed on one side of the water plate 202. The slide plate can limit the dislocation of the side plate 102 and guide the movement of the side plate 102.
[0029] Furthermore, the clamping assembly 103 includes a connecting plate 103a, which is fixedly installed on the top of the base 101. A threaded sleeve 103b is fixedly installed inside one end of the connecting plate 103a, and a threaded rod 103c is threadedly installed inside the threaded sleeve 103b. A clamping plate 103d is rotatably installed at the bottom of the threaded rod 103c. The clamping plate 103d is pushed by rotating the threaded rod 103c to clamp the metal tube 104, thereby facilitating fixing the position of the metal tube 104.

[0033] During use, the metal tube 104 is first placed on the top of the bottom support 105, and then the handle at the top of the threaded rod 103c is rotated to push the clamping plate 103d to clamp the metal tube 104. After the clamping of the clamping plate 103d is completed, the metal tube 104 is heated, and the hydraulic cylinder 201 pushes the water plate 202 and the side plate 102 to push the metal tube 104, pushing the heated metal tube 104 to deform it, thereby preliminarily forming an expansion joint.
[0034] After the side panel 102 contacts the heating position of the metal tube 104, the heat can be transferred through the water plate 202 to dissipate the heat of the side panel 102. The water inside the side panel 102 is sucked out by the water pump 205 and enters the water tank 1 206. Then, the fan group 1 208 rotates to dissipate the heat of the water inside the water tank 1 206. After that, the water enters the water tank 2 209a through the connecting pipe 207, and is further dissipated by the fan group 2 209b. Then, the water returns to the water plate 202 through the pipe 2 209c and the elastic tube 2 209d.
