4results about How to "Improve pipe bending efficiency" patented technology

The present invention discloses a fully automatic loading and unloading pipe bending production line, comprising: a pipe bending machine; an automatic loading mechanism; a feeding device, the feeding device comprising a fixed feeding rack, a movable feeding rack and a feeding control device; a feeding manipulator, the feeding manipulator is used to transfer the workpiece bent by the pipe bending machine to the fixed feeding rack. Since the feeding device adopts a structure composed of a fixed feeding rack, a movable feeding rack and a feeding control device, the feeding manipulator can place the workpiece bent by the pipe bending machine on the fixed feeding rack, and when the workpiece placed on the fixed feeding rack reaches the limit, the feeding control device controls the workpiece to move from the fixed feeding rack to the movable feeding rack, and the feeding manipulator can continue to place the workpiece bent by the pipe bending machine on the fixed feeding rack. At this time, the user can replace a new movable feeding rack or take away the workpiece placed on the movable feeding rack, and the pipe bending machine does not need to stop operating, thereby realizing continuous operation of the pipe bending machine, greatly improving the pipe bending efficiency of the pipe bending machine.

The invention discloses a pipe bending tool for an underwater Christmas tree electro-hydraulic traversing device, and relates to the technical field of underwater Christmas tree electro-hydraulic traversing devices, the pipe bending tool comprises a pipe bending tool body, a fixing mechanism and a rotating mechanism, the pipe bending tool body is provided with a bending guide rail, and the bending guide rail spirally surrounds the pipe bending tool body; the fixing mechanism is arranged on the pipe bending tool body and can fix the first end of the hydraulic pipeline to the bending starting end of the bending guide rail. The rotating mechanism comprises a sleeve and a rotating rod, the pipe bending tool body is rotationally sleeved with the sleeve, the inner side of the sleeve is connected with the bending guide rail through a guide assembly, and the guide assembly can move along the bending guide rail so that the sleeve can move and rotate along the pipe bending tool body; one end of the rotating rod is fixedly connected with the sleeve, the other end of the rotating rod can move along the bending guide rail through the pulley, and a bending channel allowing the second end of the hydraulic pipeline to penetrate is formed between the pulley and the bending guide rail so that the hydraulic pipeline can be bent along the bending guide rail.

A handheld portable electric hydraulic bar bending machine comprises an oil cylinder, a piston arranged in the oil cylinder and a pressure gathering groove formed in the center of the side wall of the left side of the piston, the side wall of the left side of the piston is attached to the inner wall of the left side of the oil cylinder, an oil hole communicated with the pressure gathering groove is formed in the outer wall of the piston, and the left portion of the oil cylinder is sleeved with a handle shell matched with the oil cylinder. A fixing seat is arranged in the handle shell, and the outer wall of the left side of the oil cylinder is attached to the right end face of the fixing seat; a limiting groove is formed in the center of the inner wall of the left side of the oil cylinder. A through hole communicated with the limiting groove is formed in the center of the outer wall of the left side of the oil cylinder; a fastening screw hole coaxial with the penetrating hole is formed in the right end face of the fixing base. The handheld portable electric hydraulic bar bending machine can be moved easily, straight pipes in different places can be bent conveniently, the bending requirements of the straight pipes of different sizes can be met, and the overall bending efficiency can be effectively improved.

This utility model relates to the field of furnace tube processing technology, and in particular to a high-efficiency bending equipment for industrial furnace tubes. It includes a processing table with a support plate fixedly connected to its center. The outer wall of the support plate has an installation groove, within which a support rod is installed. The support rod extends to the outside of the processing table and is connected to a bending mold. The outer wall of the bending mold has a circular groove, within which a furnace tube is clamped. This equipment achieves "heating and bending simultaneously" by embedding a heating coil within the bending mold and directly heating the area of ​​the furnace tube to be bent in real time via a high-frequency power supply box. This avoids heat loss during the transfer process. The heating coil directly transfers heat to the furnace tube through heat-conducting holes, and the temperature sensor provides real-time feedback, improving heating efficiency. For traditional natural cooling methods that result in insufficient hardness in the bent section of heat-resistant steel furnace tubes, and the risk of cracking from direct water cooling, this equipment avoids cracking by spraying coolant through atomizing nozzles, thus reducing the scrap rate.
