Description

Technical Field

[0001] The utility model relates to the technical field of 625 hose expansion joint processing, in particular to a processing device for 625 hose expansion joints. Background Art

[0002] 625 hose expansion joint is a kind of pipe connection workpiece made of nickel-based alloy steel. Expansion joint is also called compensator or expansion joint. It can compensate for the additional stress of pipeline caused by temperature difference and mechanical vibration. It is a flexible structure, which mainly uses the expansion and contraction deformation of the bellows to absorb the dimensional changes of the pipeline caused by stress.

[0003] A patent with announcement number CN 219520120 U discloses a metal bellows expansion joint forming and processing device, in which a first high heat dissipation clamping plate is inserted into an upper extruded workpiece, a second high heat dissipation clamping plate is installed at the bottom of the first high heat dissipation clamping plate, heat dissipation ports are distributed on the first high heat dissipation clamping plate and the second high heat dissipation clamping plate, a telescopic heat dissipation cavity is opened at the connection between the upper extruded workpiece, the lower extruded workpiece, the first high heat dissipation clamping plate and the second high heat dissipation clamping plate, an upper electric telescopic rod and a lower electric telescopic rod are installed on an operating device, and after being fixed, the lower piston rod and the upper piston rod are positioned and connected to the first high heat dissipation clamping plate and the second high heat dissipation clamping plate, and heat can be dissipated through the heat dissipation ports during use to prevent the service life of the cylinder from being shortened due to high temperature during processing, and the first high heat dissipation clamping plate and the second high heat dissipation clamping plate greatly reduce the cost for easy disassembly and replacement.

[0004] However, since the existing expansion joint forming and processing device replaces the cylinder with an electric telescopic rod, and the piston rod action end of the electric telescopic rod is directly installed on the high-heat dissipation support plate, the heat during the expansion joint processing will still be transmitted to the electric telescopic rod through the high-heat dissipation support plate and the piston rod.

[0036] During operation, since the existing expansion joint forming and processing device replaces the cylinder with an electric telescopic rod, and the piston rod action end of the electric telescopic rod is directly installed on the high heat dissipation supporting plate, the heat during the expansion joint processing will still be transmitted to the electric telescopic rod through the high heat dissipation supporting plate and the piston rod. The heat accumulation after long-term use will cause aging of the circuit inside the electric telescopic rod, and the heat dissipation effect of the high heat dissipation clamping plate is poor, which will still affect the service life of the electric telescopic rod.

When the ends of the two tilting rods 11 opposite to the pull rods 9 are squeezed inwardly at the same time, the connecting ends of the two tilting rods 11 and the two pull rods 9 will swing outwardly with the rotation connection with the two support rods 10 as the axis, thereby driving the two pull rods 9 to slide outwardly in the through hole 8, thereby driving the two inner clamping plates 5 to expand outwardly, and when the two inner clamping plates 5 expand outwardly, they will squeeze the spring 7 outwardly to shrink it, and after the spring 7 shrinks, the two inner clamping plates 5 will slide in the limiting hole 3 through the limiting rod 4.

[0037] Working principle: in the initial state, the spring 7 located in the opening of the two U-shaped fixing frames 1 will always push the two inner clamps 5 inwards so that the two inner clamps 5 fit together and the slots 12 opened between the two inner clamps 5 fit together, and at the same time, the two inner clamps 5 pull the two pull rods 9 inwards at the same time, so that the two tilting rods 11 respectively carried by the two pull rods 9 swing through the rotating connection with the support rod 10, so that the two tilting rods 11 are tilted outwards at the ends opposite to the pull rods 9, and the two U-shaped fixing frames 1 are fixedly installed in the equipment, and the limit rod 4 is set in the limit hole 3, and the spring 7 is set on the limit rod 4, the two inner clamping plates 5 are respectively installed on the ends of the limit rods 4 in the openings of the two U-shaped fixing frames 1, the pull rod 9 is installed on the side of the inner clamping plate 5 through the through hole 8, and the tilting rod 11 is rotated and installed on the pull rod 9, and the end of the support rod 10 is rotated and connected to the tilting rod 11, and then the two electric telescopic rods 14 are horizontally installed on the equipment through the positioning sleeve 2, and the roller 15 at the end of the electric telescopic rod 14 is opposite to the end of the tilting rod 11 and the pull rod 9. When working normally, by controlling the extension of the two electric telescopic rods 14, the two electric telescopic rods 14 will drive the two rollers 15 to squeeze the outer tilting ends of the two tilting rods 11 inward. When the ends of the two tilting rods 11 and the pull rods 9 opposite to each other are squeezed inward at the same time, the connection ends of the two tilting rods 11 and the two pull rods 9 will swing outward with the rotation connection points with the two support rods 10 as the axis, thereby driving the two pull rods 9 to slide outward in the through holes 8, thereby driving the two inner clamping plates 5 to expand outward, and when the two inner clamping plates 5 expand outward, they will squeeze the spring 7 outward to shrink it, and after the spring 7 shrinks, the two inner clamping plates 5 will slide in the limiting hole 3 through the limiting rod 4, and when the two inner clamping plates 5 are separated, the processed pipe fittings can be set between the two inner clamping plates 5, and after the pipe fittings are set, the two electric The movable telescopic rod 14 contracts. When the two electric telescopic rods 14 contract, under the action of the spring 7, the two inner clamping plates 5 will be squeezed inward, thereby fixing the pipe fittings, and the ends of the tilting rods 11 on both sides will tilt outwards again, thereby fixing the pipe fittings, and pouring coolant into the cooling chamber 13 can effectively reduce the heat transfer of the pipe fittings. By preventing the electric telescopic rod 14 from directly contacting the inner clamping plates 5, heat transfer to the electric telescopic rod 14 is avoided, and the expansion joint processing and fixing effect is achieved. Compared with the traditional expansion joint forming processing device, the heat insulation effect is better, and the service life of the electric telescopic rod is effectively guaranteed.
