Computer monitor local medium frequency hot induction pipe bending machinehydraulic push curved elbow

Local Intermediate Frequency Induction Heating Machine hydraulic push angled bend. It uses a pressure, temperature, speed, angle of bend sensor monitoring process. By the central processing computer system for processing data for each sensor input, to achieve simultaneous monitoring of the entire bending process, simultaneous recording of data, alarm indication is given when necessary. IF Bend process according to specifications, using this device elbow bend processing equipment to ensure the quality and safety of the elbow. Existing methods technically bend can be divided into two kinds; one is cold-formed technique, i.e., at room temperature for pipe bending, bending stress in the pipe reaches suffered plastic deformation conditions, the tube is bent; another is bending technology, high-temperature heating of a thermoplastic tube bending under the conditions. IF induction heating pipe technology is a partial bending technology. US Patent No. 4596.128,4412.442 involved is such a local medium frequency induction heating pipe technology. IF Bend elbows process specifications for frequency heating process to make provision, which provides for the heating temperature during bending, forward speed, cooling and other restrictions. Only strictly follow the process specification of requirements in order to ensure the quality of the elbow, so that the elbow does not produce will affect their life, can cause accidents hairline. Whether there are hairline in the elbow, and there is no damage to non-destructive testing methods have not bend forming tube. So IF Bend strict compliance process specifications, is to make the bend quality to meet the requirements, so that the only guarantee hairline does not exist. Implementation of a device and method which can monitor bending process parameters, so that bending process meets the requirements of process specifications IF Bend to elbow bending quality; real-time monitoring tool IF Bend the force parameters and IF electrical parameters of the power supply in order to ensure that the equipment efficient and safe operation.

Simple hydraulic pipe bender hydraulic pipe bending machine

Simple hydraulic pipe bender hydraulic pipe bending machine

A simple hydraulic bending machine, bending machine comprises a frame, hydraulic cylinders, hydraulic control systems, mold and push plate, the bracket for the tripod, the tripod top of the hydraulic cylinder is fixed, tripod top has the support beams, Die push plates are fixed to the support beam; piston rod connected to the push plate, the push plate biasing member as a tube, the tube is fixed to the mold, the hydraulic cylinder is controlled by a hydraulic control system, through hydraulic cylinder piston, complete tube bending work. Tripod has three legs, the three legs secured together at the top of the disc seat. This kind of simple hydraulic pipe bender, simple structure, easy to operate, easy to manufacture, for most types of pipe bending can be implemented as long as the replacement of the corresponding mold to complete. Existing bender general structure is more complicated, the general horizontal, bottom features a docking station. The higher the weight of the base, and difficult to move. The utility model relates to a simple hydraulic pipe bender, characteristic of this kind of simple type bender is relatively simple structure, in the case of a need to move, easy removal and installation, but does not affect the normal operation of the bender . A simple hydraulic bending machine, the bending machine comprises a frame, a hydraulic cylinder, the hydraulic control system, the mold and push plate, said bracket tripod, a hydraulic cylinder fixed to the top of the tripod, the tripod top has to be supported beam, the mold and the push plate are fixed to the support beam; piston rod connected to the push plate, the push plate biasing member as a tube, the tube is fixed to the mold, the hydraulic cylinder by the hydraulic control system, through hydraulic cylinder piston complete pipe bending work.

A multi-angle hydraulic pipe bender hydraulic pipe bending machine

A multi-angle hydraulic pipe bender hydraulic pipe bending machine

Provides a multi-angle hydraulic pipe bender, belongs to the mechanical technology. It solves the existing pipe benders were unable to question the work of the multi-angle bend. The hydraulic multi-angle bending machine comprises a frame, provided with a horizontal hydraulic cylinder on the frame, is provided at the front end of the platen and the hydraulic cylinder piston rod disposed parallel to the upper and lower ends of the two is located between the two platen, two platens There is rotated between the two blocks and the two rotation mass symmetrically disposed on both sides of the piston rod, to open a plurality of positioning holes symmetrically provided on both the pressure plate and in a side plate with positioning holes arranged in a plurality of inclined parallel columns, Solid block rotation of upper and lower ends, respectively, inserted in the corresponding positioning holes and can be rotated circumferentially in a rack attached to the side of the guide rod and the guide rod is provided in the stopper, and when the pipe through the gap between the platen When the pipe end portion can abut against the stopper. The present invention has a simple structure, convenient and practical, can multi-angle bend pipe advantages. Hydraulic pipe bending machine is a new tool has elbow function and function from the top, with a reasonable structure, safe, easy to operate, reasonable price, fast loading, easy to carry and so many advantages in the domestic hydraulic pipe bender occupy a large market share, mainly used in factories, warehouses, docks, construction, railway, automobile and other piping installation and repair. In addition to its elbow functions, but also remove the elbow parts (cylinder) from the top as a separate hydraulic machine. However, the existing hydraulic pipe bender can not be multi-angle bend, can not meet the specifications for a variety of materials and multi-angle bends industry-specific requirements, which greatly limits the use of bender. There is an existing technology for the above problem, a simple, practical and convenient, can multi-angle bend pipe hydraulic pipe bender. A hydraulic multi-angle bending machine, comprising a frame, provided with a horizontal hydraulic cylinder on the frame, characterized in that the platen is provided in the front end of the cylinder and the piston rod end portion disposed in parallel to both the upper and lower located two between the plate with two blocks and two rotational tilt rotation block symmetrically arranged on both sides of the hydraulic cylinder piston rod, the creation of multiple symmetrical positioning holes provided in the plate and positioned on the same side of the plate between the two holes on the two platens arranged in a plurality of parallel columns, the rotation block is inserted solid upper and lower ends, respectively, in the corresponding positioning holes in the circumferential direction and can rotate, at one side of the frame I and the guide bar is mounted on the guide rod has a stopper, and when the pipe through the gap between the two ends of the pressure plate pipe can abut against the stopper.
