The structure of the mechanical three-roller symmetrical bending machine is three-roller symmetrical, the upper roller in the central symmetrical position of the two lower rollers for vertical lifting movement, through the screw screw female worm drive and obtained, the two lower rollers for rotary movement, through the output gear of the reducer and the lower roller gear meshing, for rolling plate to provide torque. The disadvantage of this machine is that the plate end needs to be prebent by other… Read More »Mechanical three-roller symmetrical plate winding machine

Preparation before starting: check whether all parts are correct, fastening screws (caps) shall not be loose Hydraulic three - roller symmetrical bending machine. The brake should be normal and reliable. The distance of the drum shall be adjusted strictly according to the thickness of the plate, and overload operation shall not be allowed. Can not roll the workpiece which is higher than the mechanical performance defined category. Overdetail in operation: it is necessary to put the workpiece safely, check each… Read More »Hydraulic three - roller symmetrical bending machine using skills

The friction parts of the three-roller rolling machine mechanical symmetrical bending machine must always keep good lubrication, the lubrication requirements of the components of the three-roller mechanical symmetrical bending machine are as follows: 1. Upper roller journal lubrication, oil condition liquid injection. The oil cup is placed on the top of the fixed end of the upper roller hinge seat. Before starting each shift, the mechanical oil is injected into the oil until it flows into both sides and spills… Read More »The friction parts of the three-roller rolling machine mechanical symmetrical bending machine must always keep good lubrication

Three-roll plate machine has mechanical and hydraulic: mechanical three-roll plate machine is divided into symmetric and asymmetric. The sheet metal can be rolled into a circle, arc and cone within a certain range The workpiece. Rolling bearing is a precision part of the three-roller bending machine, so it is required to be cautious when using it. The correct use can not only achieve the desired performance effect, but also It can prolong the running time of the bearing of the… Read More »The bearing of three-roller plate winder improves service life

The specific method of installing Jude bending machine mold on the durmapress punch press is as follows: 1) Before installation, check whether the edge of the mold is sharp, whether there is a collapse, whether the punch is missing Angle. Problems should be dealt with in a timely manner durmapress punch press. 2) Before closing the mold, a silicon steel sheet should be placed between the upper and lower molds to prevent scratches during handling. 3) Before the bending machine… Read More »The specific method of installing Jude bending machine mold on the durmapress punch press is as follows

1, oil pump noise is too large (too fast heating), oil pump damage, blockage, oil dirty, oil pump suction and other problems. We also need to check if the pump speed is too high. We must choose the motor speed according to the higher rotary speed specified by the pump Hydraulic CNC bending machine . 2. Check whether the viscosity of the oil is too high. If so, be sure to replace the oil with the specified viscosity immediately Hydraulic… Read More »Hydraulic CNC bending machine running noise is too large

1, first of all, you can directly through the industrial and commercial Bureau website, query the company name 2, in order to ensure that the customer's trust is higher, you can choose to come to the bending machine company field trip. This is relatively safe. 3, to the bending machine manufacturer, we will see the strength of the company, CNC bending machine manufacturer, you can see the quality of the bending machine. Agree with the truth, if you consult the… Read More »How to judge a bending machine manufacturer is not a regular manufacturer, how to do? Today xiaobian to share their experience.

Working principle of four-roller profile bending machine: Volume of arc mode under profile bending machine, the machine of two side roll roll, can also be three or four work roll roll, the roll fixed position, two side roll around because of the rotary center for arc lifting move, hydraulic control, the displacement of the liquid crystal display, is helpful to control profile forming process, high on both sides of the roller device, to ensure the rolling quality of asymmetrical section.… Read More »Application and working principle of four-roll profile bending machine

The upper and lower working rollers of the machine are active rollers. This can avoid the possible asynchronism in the process of rolling. The linear speeds of the upper and lower working rollers are automatically matched by the hydraulic system during the rolling process. The rotary movement of the equipment is equipped with a brake device to ensure the accurate positioning of the working coil. The device runs smoothly and the winding is flexible and reliable LDW-24S profile bending machine.… Read More »Overview of LDW-24S profile bending machine
