WQJY-400 Section bending machine belongs to the hydraulic symmetrical profile bending machine. It is a general-purpose equipment specially designed for bending and forming of profiles. It can adapt to the coiling of some models of angle steel, flat iron, round steel, channel steel, square tube and round pipe. It is widely used. Boiler, chemical, mining, construction, shipbuilding and other machinery industries.

The electrical equipment used in the equipment is brand-name quality products, and the electrical components are strictly tested before installation and ensure reliable operation.

The equipment runs smoothly, has flexible control, no jamming, oil leakage and abnormal noise. The surface of the paint is flat and bright, the thickness of the paint is uniform, and there are no defects such as flow marks and leakage.


Mold diameter: φ180mm

Upper shaft diameter: φ70mm

Lower shaft diameter: φ70mm

Plate yield limit: 245MPA

Rolling speed: 4.5m/min

Main motor power: 1.5Kw

working principle

The mold on the WQJY-50 profile bending machine is driven, and the vertical movement is carried out by the hydraulic cylinder. The lower mold is circularly moved by the output torque of the motor, the reducer and the gear, and the structure is compact, and the operation and maintenance are convenient.

The transmission of the lower mold is realized by the motor through the reducer, and the gear of the output shaft end of the reducer and the gear of one end of the mold are meshed and transmitted to the lower mold, thereby driving the rotation of the lower mold.

The realization of the upper mold lifting movement is realized by the rotation of the handle.

The unloading is performed after the workpiece is rolled, the metal rod is rotated to raise the upper mold and the rolled member is taken out from between the upper and lower molds.


The WQJY-50 profile bending machine consists of two parts, the working part and the transmission part welded on the integral chassis. The working part consists of a bracket, three moulds and some auxiliary parts. The bending function of the profile is achieved by adjusting the height of the upper mould. The transmission part consists of a hydraulic station, a motor, gears and other auxiliary parts.

Hydraulic system

The main function of the hydraulic system is to drive the cylinder to make the upper roller move up and down.

The electro-hydraulic reversing valve can control the lifting movement of the upper roller; the hydraulically controlled check valve can make the working roller stay at any position.

The entire hydraulic system is designed to be reliable and reliable, and equipped with high-precision oil suction and return filters to ensure the cleanliness of the system fluid. The hydraulic oil pipe joint adopts the quick-connect joint for coal mine to ensure that the whole system has no leakage.

The main valve groups in the hydraulic system are made of quality products from Japan Oil Research. The pumps, oil filters and seals are all made by domestic famous brand manufacturers or Sino-foreign joint ventures with advanced performance and reliable quality. All hydraulic components have undergone rigorous testing and screening before entering the factory, so as to eliminate hidden troubles in advance.

The system piping is neatly arranged, convenient to operate, flexible in operation, and has an overload protection device.


Lubricating parts are required for each friction part of the machine to keep the machine running and prolong its service life.

Inject the lubricating oil into the gearbox, generally using the mechanical oil of the grade HJ-40. Grease must be applied regularly on the gears.
