《CNC plate rolling machine》

Hydraulic plate rolling machine divided into three and four rolls:

This machine is hydraulic type three-roll plate coiling machine, the upper prebending and coil plate can be formed at one time, the coil plate precision is high.

This machine roller can be lifted vertically, can also move horizontally, vertical lifting for hydraulic transmission, through the hydraulic oil in the hydraulic cylinder acting on the piston rod to obtain. Horizontal movement through the worm gear box, worm gear and screw screw master mechanism to transfer torque, the lower roller is provided with a roller and can be adjusted, the upper roller is a drum shape, improve the straightness of the product.

Due to continuous bending, and high precision end prebending, resulting in superior precision products; In addition, the upper roller is shaped like a drum, and the supporting roller is adjusted to roll the ideal product from a wide range of thin and thick plates. Rich bending shapes: The large upper roll CNC universal winding machine has different shapes such as O type, U type, and multi-section R.

High precision end prebending: When the end is prebending, the straight side length can be set freely, and the high precision end prebending can be implemented under certain pressure when the upper roll is pressed.

Prebending is achieved by moving the upper roll horizontally so that the upper roll is in an asymmetric position relative to the lower roll. When rolling, the motor and reducer drive two lower rollers. Due to the constant elevation of the lower roller, it is easy to feed and operate.

It is used to roll low carbon steel (such as Q235-B, 20kg, 20R) and low alloy steel into a cylindrical shape at normal temperature. Widely used in petroleum, chemical, boiler, shipbuilding, hydropower, metal structure and machinery manufacturing industries.

What are the main functions of the universal plate rolling machine?

Universal plate rolling machine is a continuous point bending of the plate molding machine, the ordinary symmetrical three-roll plate rolling machine in the plate, the general plate at both ends will leave a certain width of the dead edge, so that after the roll into the cylinder, the pre-bending function is to deal with the dead edge, combined into a cylinder. The workpiece rolled out by the plate rolling machine has more straight edges at both ends and needs to be welded together and then rolled up takes time and reduces the work efficiency.

Main components of universal plate rolling machine:

(1) The upper and lower roller of the plate rolling machine: it is an important part of the plate rolling machine, and the material is forged high-quality carbon steel.

(2) Plate rolling machine frame: divided into the left and right frame each, the frame is equipped with lower roller bearings. The frame is provided with a square buckle rod, and the upper end of the screw rod is hinged with the bearing seat at both ends of the upper roll. A worm gear pair and a spiral pair are arranged in its lower part. The nut in the worm gear rotates to cause the upper roll to rise or fall.

(3) Reducer: The ZSY280 hard-tooth surface reducer is installed on the channel steel base together with the cushion height.

(4) The unloading device of the plate rolling machine: installed on the side of the reducer for balancing the upper roll when unloading; Unloading and recovery by cylinder.

(5) Base: welded by section steel and steel plate. The frame, reducer, motor, etc. are installed on it to form a whole.

(6) Electrical part: all installed in a control box, easy to operate.

The electronic control system of universal winding machine equipment consists of electric control cabinet and operation console. Power supply 380V/50HZ. The main switch has the function of short protection and overload protection of the main motor. The forward and reverse rotation of the motor is controlled by AC contactor; The control circuit adopts relay control, reliable operation and long life. Finished product control button and indicator light are provided on the control table to complete the operation and working state control of the whole machine.

Universal plate rolling machine products are widely used in boiler, shipbuilding, petroleum, woodworking, metal structure and other machinery manufacturing industries, universal plate rolling machine as a special machine, it occupies an important position in industrial basic processing. All steel molding for cylindrical type, almost all with a rolling machine roll. It is used in automobile, military and other aspects. According to different requirements, it can roll out steel columns that meet the requirements, and it is a very practical instrument.
