The induction heating pipe bending machine is a new type of pipe bending tool with pipe bending function and jacking function. It has many advantages, such as reasonable structure, safe operation, convenient operation, reasonable price, fast loading and unloading, and multiple functions. It has a large market share in the country. Before the machine operation of the pipe bending equipment, promise no-load operation. After the normal operation is recognized, the pipe bend is set. The pipe mold should be selected according to the processed pipe diameter and placed in order. During operation, non-operating and auxiliary personnel are not allowed to stay and watch near the machine. After the operation, the power supply should be blocked, the electrical box should be locked, and the well should be well maintained.　　
The initial interval between the machining jaws of induction heating pipe bending machine is slightly larger than the sum of the jaw interval after upsetting, the top stroke of the pipe bending machining and the burning allowance. It is generally said that the thickness of the steel strip produced by pipe bending is larger, and the initial gap between the jaws is also larger; the width of the steel strip is larger, and the initial gap between the jaws is also larger. The gap between the jaws of the pipe bending machine is selected according to the thickness of the strip. If the machining interval of the pipe bending is too large, it will simply cause lap welding and change. If the interval is too small, the temperature difference along the welding section will be large. The thinner the steel strip processed by the pipe bending machine is, the smaller the jaw interval should be after upsetting. Regarding steel strips with a thickness of 2-4.5 mm, pipe bending machining usually selects an upsetting jaw spacing of 12-18 mm.

How to operate the pipe bending machine to make the arc thinner in daily operations? Believe that this problem has always plagued everyone, the following pipe bender manufacturer-Zhongsi Technology Xiaobian will share with you the arc thinning technique of the lower pipe bending machine.
The speed of boost and push is determined according to the actual situation of the pipe bending, so that it matches the speed of the hydraulic pipe bender. At the same time, it should be checked whether the advance of the mandrel installation is appropriate, and adjustments should be made when it is inappropriate. Based on the bending and cracking of the outer arc of the pipe, the reasons should be carefully analyzed. First, ensure that the pipe has a good heat treatment state, and the weld of the seam steel pipe should not be in the force direction of F1 and F2, that is, do not clamp it directly Die and bending wheel die; Check whether the pressure of the compression die is too large after removing the factors of the pipe material, and adjust it to make the pressure appropriate. For the newly used mandrel, check whether its diameter is too large. If the diameter is too large, it should be ground and ensure that the mandrel and the inner wall of the pipe have good lubrication to reduce the resistance of the elbow and the friction between the inner wall of the pipe and the mandrel. Take appropriate measures to avoid machine jitter. For wrinkling on the inside of the arc, corresponding measures should be taken according to the wrinkling position. If the front tangent point is wrinkled, the mandrel position should be adjusted forward to make the mandrel advance appropriately to achieve reasonable support for the pipe when the pipe is bent; When the rear cutting point is wrinkled, an anti-wrinkle block should be installed, and the anti-wrinkle block should be installed in the correct position, and it can be attached to the platform with the pipe bending machine. Adjust the pressure of the compression mold (wheel) to make the pressure appropriate.

Our country’s pipe bender equipment is also mature and stable in terms of quality and technology for hydraulic pipe benders, automatic pipe benders, pipe cutting machines, and pipe shrinking machines. The birth of new products and technologies, we are all in a state of groping, so the performance of the machine is relatively fragile, but today’s pipe processing equipment is stable and routine, so after purchasing the machine tool, you only need to maintain it carefully. A good machine tool can be used for a long time.

But what problems often occur in daily use of pipe bending opportunities? Usually there is a problem with the hydraulic area, because when the machine is bending the pipe, the pipe is cut with a metal circular saw, which will leave a lot of small iron pins. If these iron pins are not cleaned up, they will be taken directly to the pipe bending machine to process the pipe. Many pipe bending machine molds have mandrels to bend, because they are afraid that the fullness is not high enough, they will wrinkle or collapse. And other phenomena.       In this way, these small iron pins will fall out when the pipe bender inserts the pipe into the mandrel, and the iron pins that have not been cleaned will fall into the oil tank inside the fuselage. We all know that the hydraulic pipe bender uses an oil pump to input hydraulic pressure. The oil relies on solenoid valves to provide hydraulic power. Therefore, after these iron pins enter the fuel tank, most of them will be filtered out by the filter in our oil inlet pipe, but a small part of the iron pins will enter the oil pump, so that the iron pins sucked into the oil pump will enter the electromagnetic Inside the valve, and these iron pins cannot flow in the solenoid valve, causing the hydraulic solenoid valve to be blocked, and the hydraulic oil cannot flow. This will cause a corresponding action failure and cause the hydraulic pipe bender to fail to work normally.       Even if this phenomenon occurs, there is no need to panic. Just manually press a certain action according to the buttons on the control panel, and then look at the indicator light on the solenoid valve to see which solenoid valve is not working, and then close the movie. Then use a 4mm Allen key to remove the solenoid valve fixed on the oil separator plate. After cleaning the solenoid valve with clean kerosene, blow the inside with an air gun to clean the iron pins inside, and then install it to solve the problem.

Before operation, first check whether the smooth points of the pipe bender are short of oil, whether the movement mechanism can be loosened, and whether the safety protection installation can be securely installed. It is to be confirmed that the front can be operated. Start the elbow oil pump, whether the system pressure can be maintained within the specified range, if it is high, it will damage the hydraulic components and waste the power supply, if it is too low, it will affect the work. Adjust the required position and angle of the parts. Adjust the positioning of the machine to the required length. Adjust the vertical lifting rail so that the guide mold pressing cylinder can clamp the iron pipe tightly. The clamping cylinder can clamp the iron pipe.       

The normal operation is to put the workpiece into the bending mold, and the front end is contacted and positioned, and the foot switch is stepped on to complete. When operating the pipe bender, you must concentrate your mind and stop putting your hands or other objects in the work area. In case of emergency, press the emergency stop button, and then turn the rotary switch to the manual position and reset it manually. If something goes wrong, promptly Repair. After the work is finished, cut off the power supply and do a good job of cleaning and smoothing. The CNC pipe bender is mainly used for electric power construction, highway and railway construction, boiler, bridge, ship, furniture, decoration and other aspects of pipe laying and repair. It has the advantages of multiple functions, reasonable structure, simple operation, convenient movement, and fast installation.       

In addition to the pipe bending function, this machine can also use the oil cylinder as a hydraulic jack. Relative to the CNC pipe bending equipment, it is inexpensive and easy to use, occupying the leading product position in the domestic pipe bending machine market. Numerical control pipe bending machine, can stop one bending radius (single-mode) or two bending radii (dual-mode) winding bending of pipes in cold state. It is widely used in the bending of various pipe fittings and wires in automobile, air-conditioning and other industries. . The pipe bending machine is mainly used for plastic forming of pipes.

How to deal with the overheated bearing of automatic pipe bender?

① Too much or too little grease in the bearing of pipe bender;

The boosting and pushing speeds are determined according to the actual situation of the pipe bending to match the speed of the hydraulic pipe bending machine. At the same time, check whether the advance of mandrel installation is appropriate, and adjust if not. Based on the outside bending crack of pipe arc, the reason should be analyzed carefully. First, the pipe should be in good heat treatment state. The weld of seam steel pipe should not be in the stress direction of F1 and F2 as far as possible, that is, not facing the clamping die and bending wheel die. After eliminating the factors of pipe, check whether the pressure of pressing die is too large, and adjust the pressure to make it appropriate.For the newly used mandrel, it is necessary to check whether its diameter is too large. When the diameter is too large, it is necessary to grind it, and ensure that the mandrel and the inner wall of the pipe have good lubrication, so as to reduce the resistance of the elbow and the friction between the inner wall of the pipe and the mandrel. At the same time, appropriate measures are taken to avoid the shaking of the machine tool. For the inner wrinkle of the circular arc, corresponding measures should be taken according to the wrinkling position. If the front point is wrinkled, the position of the mandrel should be adjusted forward so as to make the mandrel advance ahead of time, so as to achieve the reasonable support for the pipe when bending. If the back tangent point is wrinkled, an anti wrinkle block should be added to make the installation position of the anti wrinkle block correct, which can be attached to the die of the pipe bender, and the pressure of the pressing die (wheel) should be adjusted to make the pressure appropriate.
